Description

FIELD

The present disclosure relates generally to liquid dispensing systems and more specifically to liquid dispensing systems having a reusable dispensing fixture and a reusable spray dispenser.

BACKGROUND

Various configurations of reusable container bottles or vessels, coupled with reusable delivery systems, for carrying and dispensing liquid compositions, particularly pest control compositions, such as insecticides, insect repellents, fungicides and/or herbicides, designed for easy manual portability and non-commercial/consumer use, are known.

Older technology has included a generally cylindrical container vessel coupled with a removable/replaceable top fixture. The top fixture sealingly fits about a top opening in the vessel, and is equipped with a hand-operated air pump and check valve system, configured to pump air into the vessel and thereby pressurize it. The top fixture also typically includes an attached dip tube configured to extend from an inside opening in the top fixture, to a distal intake end. The dip tube typically has a length such that the intake end will be disposed proximate the bottom of the interior of the vessel, when the top fixture is completely installed on the vessel. The proximal end of the dip tube is connected to an underside of the top fixture, and a further liquid passageway goes from the connection, through and out the fixture, to and through a suitably convenient length of flexible delivery hose or tube, and then to a dispensing wand having a hand-operable liquid release valve and a rigid spray tube, ending at a dispensing nozzle. Upon pressurization of the vessel via operation of the hand air pump, liquid is forced under pressure up the dip tube, through and out the top fixture, and out to the wand.

Variations of newer technology have included a non-pressurized bottle coupled with a dispensing fixture and a liquid pump. The liquid pump may be operably fluidly connected with a dispensing fixture, or alternatively, with a dispensing wand. The dispensing fixture may include a trigger and dispensing nozzle, or may be connected to a dispensing wand by a suitably convenient length of flexible delivery hose or tube. In some examples the liquid pump is disposed inside a handle of the dispensing wand. In some examples the pump is manually operated; in other examples it is driven by an electric motor. The liquid pump may be activated to pump liquid from the bottle, by a control mechanism such as a trigger, button or switch, disposed on the dispensing fixture or on the wand.

Although these known systems can be useful and effective for dispensing liquid compositions, such as liquid pest control compositions, they also have shortcomings, leaving room for improvements.

Description of Examples of Features

Referring to FIGS. 1 and 2, a liquid dispensing system as contemplated herein may include a bottle 20, a removable/reattachable dispensing fixture 100 and a spray wand 300 or some other type of spray dispenser, such as a trigger spray dispenser 500. The dispensing fixture 100 may comprise a front wall 100a, a rear wall 100b opposite the front wall, and side walls 100c extending between the front wall 100a and the rear wall 100b, where at least one of the side walls 100c comprises a protrusion 130.

Either the bottle or the dispensing fixture may be provided with a carry handle 110, configured to allow a user to carry the system conveniently with one hand. The carry handle may be separately formed and attached, or may be integrally formed with the bottle or the dispensing fixture. In another example, the bottle may be devoid or free of a carry handle. Spray wand 300 or trigger spray dispenser 500 may be fluidly connected to the dispensing fixture by a flexible outflow tube 65 of a suitably convenient length, whereby a user may carry the bottle with one hand and use the spray wand 300 or trigger spray dispenser 500, to dispense liquid drawn from the bottle to surrounding application sites within a reasonably convenient distance therefrom, with the other hand. The spray wand 300 may include a substantially rigid spray tube 305 terminating in a distal spray nozzle end structure 311, which receives liquid supplied through the wand housing via supply from the outflow tube 65. The trigger spray dispenser 500 may include a spray nozzle 504, which receives liquid supplied through the trigger spray dispenser housing 502 via supply from the outflow tube 65, a trigger spray actuator 506, and a handle 508 comprising a front wall 508a, a rear wall 508b opposite the front wall, and side walls 508c extending between the front wall 508a and the rear wall 508b. The trigger spray dispenser housing 502 may comprise a pump.

The spray dispenser need not be a trigger spray dispenser 500, as shown in FIGS. 34A-34G. The spray dispenser may be any other suitable spray dispenser available in the art. Similarly, the spray dispenser may comprise any type of spray actuator (not just a trigger spray actuator), such as a button (e.g., push-button) actuator, a lever actuator, a toggle actuator, or a knob actuator.

As reflected in FIGS. 2, 26 and 27, the wand 300 and spray tube may be configured such that spray tube 305 may be placed in folded/stowed (e.g., as shown in FIGS. 2, 26) and extended/deployed (e.g., as shown in FIG. 27) positions. The dispensing fixture 100 and/or the bottle 20 may be provided with an attached wand stowing fixture 350 configured to hold and store the wand 300 closely thereto when the system is not in use. The wand 300 may be provided with a spray button, switch or trigger 320, wherein the wand 300 and/or dispensing fixture 100 is/are configured to be activated to deliver liquid from the bottle to the nozzle, upon engagement/operation of the button, switch or trigger 320 by a user.

As reflected in FIGS. 34A-34G, the dispensing fixture 100 and/or the bottle 20 (not shown) may be provided with a protrusion 130 configured to hold and store the trigger spray dispenser 500 closely thereto when the system is not in use. The dispensing fixture 100 may comprise a front wall 100a, a rear wall 100b opposite the front wall, and side walls 100c extending between the front wall 100a and the rear wall 100b, where at least one of the side walls 100c comprises a protrusion 130. The handle 508 of the trigger spray dispenser 500 may comprise a front wall 508a, a rear wall 508b opposite the front wall, and side walls 508c extending between the front wall 508a and the rear wall 508b, where at least one of the side walls 508c comprises a recess 512 complementary to the protrusion 130 in at least one of the side walls 100c of the dispensing fixture 100. The recess 512 in the at least one side wall 508c of the trigger spray dispenser 500 handle 508 and the protrusion 130 in the at least one side wall 100c of the dispensing fixture 100 may be any shape or size, provided that the recess 512 is of complementary shape and size to the protrusion 130. The complementary shape and size of the recess and the protrusion allows for an intuitive, user-friendly, and secure way to store the trigger spray dispenser close to the bottle. The protrusion 130 and the recess 512 may also be configured such that the trigger spray dispenser 500 may be placed and stored in a number of different orientations. As such, the user need not precisely and painstakingly orient the trigger spray dispenser in order to securely store it with the bottle. In order to further prevent the trigger spray dispenser from shifting during storage or shipment, the surface of the recess and the surface of the protrusion may be provided with cooperating mating features to limit separation between the recess and the protrusion.

The cross section (taken parallel to the side walls 508c) of the recess 512 may be a circle, an ellipse, an oval, a star, a square or other polygon, or an irregular shape. Similarly, the cross section (taken parallel to the side wall 100c) of the protrusion 130 may be a circle, an ellipse, an oval, a star, a square or other polygon, or any other suitable shape. The recess 512 may be a through opening extending through the handle 508, as shown in FIGS. 34A-34G. The shape of the through opening may also be circular, elliptical, oval, triangular, square, rectangular, or other polygonal shape, or any other suitable shape. The recess 512 and the protrusion 130 may have symmetrical shapes. Preferably, the recess 512 and the protrusion 130 have a symmetrical, elliptical shape, as shown in FIGS. 34A-34G. The shape of the recess 512 and the protrusion may be same as the shape of the handle 110 of the dispensing fixture 100.

Alternatively (not shown), the protrusion may be provided on at least one side wall 508c of the trigger spray dispenser 500 handle 508. At least one side wall 100c of the dispensing fixture 100 may then be provided with a recess complementary to and configured to receive the protrusion.

The bottle 20 may be formed or molded from any suitable material including but not limited to metal (e.g., brass, copper, stainless steel), glass, or polymer/plastic. For reasons of material cost, manufacturing efficiency, durability and avoidance of fouling, corrosion and/or reactivity with liquid compositions contemplated herein, it may be preferred that the bottle be manufactured from plastic, preferably a plastic formulated predominantly, or entirely, of a polyethylene such as HDPE (high density polyethylene), or a polyester such as polyethylene terephthalate (PET), modified extrusion-grade PET (EPET), or polypropylene (PP), or combinations thereof. Where high clarity and transparency are desired, PET or EPET may be preferred.

The bottle 20 may be formed of a substantially colorless, translucent or transparent material (for example, PET or EPET) to allow a user to visually ascertain the quantity of liquid product remaining in the bottle 20. In some examples, a substantially colorless, translucent and/or transparent bottle may be desired for the purpose of implying a message of transparency to the consumer/user, with respect to disclosure and/or safety of contents, particularly when the liquid product is also substantially colorless and/or clear. For purposes herein, there term “substantially colorless,” with respect to a plastic bottle, means that that plastic from which the bottle is formed has less than 1 percent by weight, to, preferably, substantially 0 percent by weight, inorganic pigmenting agent(s) added to the plastic resin formulation from which the bottle is formed. For purposes herein, the terms “clear” and “substantially colorless,” with respect to a liquid product, have the meanings ascribed to those terms in co-pending U.S. provisional patent application Ser. No. 63/355,134, the disclosure of which is incorporated herein by reference.

The bottle 20 may have an interior volume 22 configured to contain from about 800 g to about 4,500 g, or from about 1,000 g to about 2,500 g or from about 1,500 g to about 2,000 g of a liquid composition. The bottle 20 may have a maximum width from about 80 mm to about 250 mm, or from about 100 mm to about 200 mm or from about 140 mm to about 180 mm. The bottle 20 may have a maximum depth from about 50 mm to about 150 mm, or from about 60 mm to about 120 mm, or from about 60 mm to about 100 mm. The bottle 20 may have a width to depth ratio from about 4:1 to about 1.1:1, or form about 3:1 to about 1.25:1, or from about 2:1 to about 1.5:1. The bottle 20 may have a height from about 150 mm to about 400 mm, from about 175 mm to about 350 mm, or from about 225 mm to about 275 mm. The dimensions of the bottle may be selected to hold a sufficient amount/weight of liquid composition (enough composition to treat one or multiple target areas/surfaces of varying sizes, once or multiple times, e.g., multi-use product), while still being easily manipulated by a consumer, especially when the bottle is devoid of a handle or through hole.

The dispensing fixture 100 may include a main housing 101 (see, e.g., FIG. 6), and the wand 300 may include a wand housing 300a (see, e.g., FIGS. 20, 21), each being formed to hold, and accommodate any required constrained movement, of other operable components of the respective dispensing fixture 100 and spray wand 300, in suitable positions with respect thereto. It may be preferred that the main housing 101 and wand housing 300a also be made of plastic, for reasons identified above. For greater rigidity, toughness and retention of structural integrity through extended and repeated use, it may be preferred that these housings be formed from a more rigid, tougher plastic such as acrylonitrile butadiene styrene (ABS), polypropylene, polycarbonate, and mixtures thereof, and preferably ABS.

Starter Package Security, and Convenient Bottle Replacement Features

It has been learned to be desirable that a liquid dispensing system provided with a filled bottle 20, dispensing fixture 100 and spray wand 300 or other type of spray dispenser (e.g., trigger spray dispenser 500) that are protected from accidental or unintended activation, or leakage of liquid product in the bottle, prior to consumer purchase. Accordingly, a starter package may be configured and assembled as described below.

Referring to FIGS. 3-5, a bottle 20 defining and enclosing an interior volume 22 may be provided and filled with liquid product/composition. A main portion of bottle 20 may have extending therefrom a neck 25, which terminates with a rim 26. The neck may have an inner diameter of from about 25 mm to about 60 mm, or from about 30 mm to about 55 mm, or from about 35 mm to about 50 mm. The neck may have an outer diameter of from about 25 mm to about 60 mm, or from about 30 mm to about 55 mm, or from about 35 mm to about 50 mm. The neck may have a height from about 10 mm to about 35 mm, from about 15 mm to about 30 mm or from about 18 mm to about 25 mm. Rim 26 substantially occupies a single plane 26p to facilitate efficient sealing thereagainst, and circumscribes and defines a main opening in the bottle, to the interior volume 22. The main opening and/or the rim 62 may have a circular configuration (e.g., when viewed from above in the non-limiting examples depicted) to facilitate efficient sealing thereagainst, and to accommodate and facilitate operation/fastening/removal of a screw-on or snap-on cap, where desired.

Below or spaced from the rim 26 the neck may have a first retaining feature 28. In some examples, first retaining feature 28 may be a configuration of outwardly projecting helical screw threads 28 formed about the neck, as suggested in the figures. Alternatively, first retaining feature 28 may be one or more outward projections adapted to cooperate, e.g., with a snap-on cap or fitted cap, e.g., a single circumferential ridge structure, or a series of circumferentially arranged ridge or projecting structures (not shown). In other examples, first retaining feature 28 may be a configuration of inward grooves, in the form of negative screw thread grooves or other circumferentially arranged grooves. In other examples, first retaining feature(s) 28 may be disposed inside the neck, spaced from the rim, and have the form of helical threads projecting radially inwardly from internal neck profile 25i, circumferentially-arranged ridge or projecting structures projecting radially inwardly from internal neck profile 25i, or even negative threads in the form of helical grooves projecting radially outwardly from inner neck profile 25i, or circumferentially-arranged grooves or cavities projecting radially outwardly from internal neck profile 25i. These arrangements, and others not specifically described but contemplated herein, may be configured to cooperate with cooperating/mating features of a suitable cap, to hold the cap in place in sealing configuration over the rim 26 and/or within the main opening, and seal the main opening such that liquid contents of the bottle are securely retained therein without leakage, even when the bottle is laid on its side or inverted.

As suggested above, the filled bottle may be provided with a cap 50 configured to sealingly fit and/or be secured over the rim and/or within the main opening. In the particular non-limiting example shown, cap 50 may be provided with interior, inwardly projecting helical threads (not specifically shown) adapted to cooperate with first retaining feature 28 (as shown, in the form of outwardly projecting helical threads), such that cap 50 may be screwed onto the neck, over the rim. If needed or desired, cap 50 may be provided with an inside gasket (not shown) to facilitate sealing against rim 26. In the configuration shown in FIG. 5, the cap may be uncrewed to open the bottle. In other configurations, as suggested above, first retaining feature 28 and cap 50 may be configured to seal and close the main opening via other features, such as a ring-snap configuration, etc.

As reflected in FIGS. 4 and 5, neck 25 may be provided with a second retaining feature 29. Second retaining feature 29 may have the form of a circumferential ridge, or circumferentially arranged series of formations, projecting radially outwardly from outer neck profile 25o. The second retaining feature 29 may have a height measured along the longitudinal axis of the bottle 20 of from about 1 mm to about 4 mm, or from about 1.25 mm to about 3 mm or from about 1.5 mm to about 2.5 mm. The second retaining feature 29 may project from about 2 mm to about 8 mm, or from about 2.5 mm to about 6 mm, or from about 3 mm to about 5 mm radially outward from the neck. The second retaining feature 29 may be from about 1.5 mm to about 6 mm, or from about 2 mm to about 5 mm, or from about 2.5 mm to about 4 mm above the bottom of the neck 25. The second retaining feature 29 may be from about 10 mm to about 35 mm, or from about 15 mm to about 30 mm, or from about 18 mm to about 25 mm below the rim 26. Cap 50 may be provided with an effectively similarly shaped and size third retaining feature 51, projecting radially outwardly from the main outer side surfaces of the cap. In some examples, the third retaining feature 51 and the second retaining feature 29 have identical shapes and/or dimensions. In other examples, second retaining feature 29 and third retaining feature 51 may be radially inwardly-projecting grooves or cavities, rather than outwardly-projecting ridges or formations.

The functions of second retaining feature 29 and third retaining feature 51 will become apparent now as follows, with reference to FIGS. 6-9. In a starter package, the liquid dispensing system may be provided with a suitably shaped and sized spacer 120, disposed between the bottle 20 and a dispensing fixture 100. The dispensing fixture 100 may be provided with one or more latching jaws 105, positioned and configured to latchably engage third retaining feature 51, when a cap 51 is present, and thereby hold the dispensing fixture 100 to the bottle via latching to the cap 50. The spacer 120 may be made of any material sufficient to provide suitable structural integrity and may be formed to be a visual extension of or visual complement to the shapes of the bottle and the dispensing fixture 100. It may be formed of a material that is tinted, pigmented or printed in one or more colors selected to visibly contrast with color(s) of the bottle and/or the dispensing fixture, to make it visually distinct from the bottle and dispensing fixture. It may be made of paper, paperboard, cardboard or other cellulose pulp-based material, for purposes of manufacturing and cost efficiency and also for purposes of conveying an implicit message to the consumer that it is disposable upon setup/activation of the system.

The one or more latching jaws 105 may be housed and held within main body 101 of dispensing fixture 100, which may have tracks 108 or other features therein that provide for suitably constrained movement of latching jaws 105 between latched and unlatched positions. One or more latching jaws 105 may be biased in a latched position by one or more latch spring(s) 107, acting directly or indirectly on the latching jaw 105 and on the main body 101. The dispensing fixture may be further provided with actuators 106 for one or more, or all, of the latching jaws included, by which a user may cause a latching jaw 105 to move from a latched position to an unlatched position. As suggested in FIG. 8, the dispensing fixture may be provided with at least two substantially opposing latching jaws 105, operably linked to two opposing latch actuators 106 via latch actuator connectors 106a, whereby a user may conveniently opposingly press or squeeze actuators 106 toward each other with a single hand, to move corresponding opposing latching jaws 105 away from each other, to unlatched positions, and if needed, using the other hand to hold or steady bottle 20 and/or wand 300.

Referring to FIG. 6, thus, a user may move latching jaw(s) 105 to unlatched position(s) to enable the dispensing fixture to be lifted and removed from the bottle 20 and cap 50 in a simple and easy way. The user may then lift and remove spacer 120 and remove cap 50 from bottle 20 (in that order, or alternatively, remove the cap first, and then the spacer). Referring to FIG. 7, the user may then lower dispensing fixture 100 over the neck and urge it downwardly, whereupon latching jaws 105 may be urged open to unlatched positions (if e.g., they are biased in closed/latched positions as described above) via engagement of second retaining feature 29 with radiused lower edges, or chamfers 105a, on latching jaws 105. Urging of latching jaw(s) 105 to unlatched positions upon downward force and movement, with respect to bottle 20, may be facilitated by inclusion of a rounded/radiused and/or chamfered upper edge 29a on second retaining feature 29 (illustrated in, e.g., FIG. 5.) Where the latching jaw(s) 105 are biased toward a latching position, e.g., by spring(s), once they are urged down over a retaining feature 29 on the neck of the bottle, with an appropriately shaped retaining feature 29 they will emit an audible snap or click sound as they move to the latching position(s), indicating to the user that latching has been accomplished. To provide or enhance this function, as well as to provide more secure latching, second retaining feature 29 may be formed with a non-graduating or abrupt/sharp lower transition 29b at a lower edge thereof, to a lower surface of the retaining feature, such that once the upper edges of latching jaw(s) 105 are moved downwardly and clear lower transition 29b, they are free to snap to the latched position toward which they are biased, similar to the manner in which an ordinary spring-biased door latch bolt snaps into latched position when an ordinary door in a house is pushed into its frame without turning the door knob, and the latch bolt clears the proximate edge of the opening in the strike plate.

After dispensing fixture 100 is lowered to a position in which latching jaw(s) 105 may cooperate with and clear second retaining feature 29 and move to latched position(s), dispensing fixture 100 is latched to bottle 20, as suggested in FIG. 7. The dispensing fixture and the bottle may be formed with cooperating/mating features that facilitate accurate alignment and secure positioning and seating of the dispensing fixture on the bottle and neck.

Utilizing a system having the features described above, a user may conveniently affix the dispensing fixture to a first bottle that is new and filled with liquid product, in a simple and easy way. When the first bottle is emptied of liquid product through operation of the dispensing system, the user may unlatch the dispensing fixture from the bottle in the same manner it was first unlatched from the cap 50 as described above, procure a second (replacement) bottle filled with liquid product and having a neck configuration that is provided with a retaining feature identical or substantially similar to that of the first bottle, remove a cap therefrom, and latch the dispensing fixture to the second bottle (e.g., refill bottle) in a convenient and easy way, with minimized chance that the user will be required to have hand or skin contact with the liquid product.

As suggested in FIGS. 1, 2 and 7, it may be desired that dispensing fixture main body 101 and bottle 20 be imparted with cooperating mating features and outer shape profiles that provide substantial shape profile continuity where the two components meet at and along surface abutment 99, when they are assembled together, over a majority of the path of abutment 99 along/about the outer surface of the assembled package. This may be desired for reasons of esthetics, ergonomics, intuitive non-verbal guidance to a user concerning how the dispensing fixture and bottle are designed to fit together, and/or efficient package volume/use of shipping and storage space. “Substantial shape profile continuity” means that there is no substantial step change in surface contour at the surface abutment 99, other than a minor ridge or groove thereat, having a width less than 5 mm, resulting from variations within manufacturing tolerances and/or minor fit imperfections.

As will be explained in more detail below, the dispensing fixture 100 may be provided with a liquid outlet coupling 60 that is configured to engage the bottle and neck about the main opening. In a starter package prior to removal of spacer 120 and cap 50, liquid outlet coupling is prevented from engaging the bottle neck, by cap 50. After removal of spacer 120 and cap 50 as described above, however, upon proper alignment and seating, liquid outlet coupling 60 may engage the bottle neck at the main opening, as reflected in FIG. 7.

Vacuum Relief Features

As liquid product is removed from the interior volume 22 of bottle 20 through use of the dispensing system by a user, a vacuum will develop inside the bottle, unless the system includes a vacuum relief system. A vacuum inside the bottle will reduce the ability of a pump to draw liquid from the bottle.

Referring now to FIGS. 10A-10C, 11A-11B, 12, 13, 14A-14B, bottle 20 may be provided with a vacuum relief system that allows ambient air to be drawn into the bottle, to occupy the portion of the interior volume 22 vacated by withdrawn liquid product. A vacuum relief system may include a vacuum relief port 41, providing fluid communication between the interior volume 22 and the outside environment, optionally accompanied by an automatic one-way valve such as a check valve. The optional automatic one-way valve may be located so as to be operably associated with the vacuum relief port and be configured to automatically permit air to flow from the outside environment, through the vacuum relief port 41, into the interior volume, upon development of a vacuum (i.e., pressure within the interior volume 22 that is lower than ambient pressure). At the same time, the optional automatic one-way valve may be configured to automatically restrict or prevent fluid flow from the interior volume 22 out through the vacuum relief port 41, in the event that pressure at the valve is greater at the interior side than at the outside of the automatic one-way valve and/or port 41, as might occur when for example, bottle 22 is overturned such that liquid within the bottle and under pressure of its weight contacts the valve and/or port 41. In some examples, the optional automatic one-way valve may have the form of a gravity- or spring-operated check valve (not shown). In some examples, the automatic one-way valve may have the form of a flap check valve, including a movable flap disposed over the port 41 at its interior opening. The vacuum relief port 41 may be provided in the bottle 20 itself, e.g., through a wall thereof, preferably a wall along a top or upper region where the interior opening of the port will not be below the level of liquid in the filled, upright bottle.

A vacuum relief port 41 or system of ports and/or an optional associated automatic one-way valve (e.g., check valve) can be provided with, in and/or through any component(s) of the system where a port or ports can be configured to provide fluid communication between the interior volume 22 of bottle 20, and the outside environment. To ensure proper functioning of each, the fluid pathway of the vacuum relief port 41 or system of ports is separate and distinct from, i.e., not in fluid communication with, liquid passageway(s) provided to convey liquid product out of the bottle via activation of a pump (with the exception, however, that vacuum relief port(s) 40 and liquid dispensing passage 43 may each be in fluid communication with the interior volume 22 of bottle 20).

In some examples, a vacuum relief and/or optional check valve system may be provided in a component provided with the bottle. For example, a filled bottle 20 may be supplied with a fluid passage fitting 40. A fluid passage fitting 40 may be adapted and formed to fit over the rim and/or within the main opening of the bottle (i.e., within the neck). Fluid passage fitting 40 may be adapted to screw onto the neck 25, to press/friction fit within the neck and main opening, or (as shown in FIG. 13) to snap fit over the rim via e.g., engagement of a rim attachment structure on fitting 40, with a rim lip 27 on the neck.

Fluid passage fitting 40 may be provided with a fluid inhibiting element 70, which may be disposed on top of the liquid dispensing passage 43 of the fluid passage fitting 40. The fluid inhibiting element may inhibit the (vertical) expulsion of fluid through the liquid dispensing passage 43 and out of the bottle, when the bottle 20 is uncapped and squeezed by a consumer-user, e.g., as the consumer-user grips the bottle 20 to pick it up (particularly a bottle that is devoid of a carry handle). A fluid inhibiting element 70 is particularly preferred for liquid pesticide products, to minimize the chances of accidental contact with a consumer-user.

Fluid passage fitting 40 may be provided with a coupling receptacle 40a in fluid communication with a liquid dispensing passage 43 through a draw bib 46. The fluid passage fitting 40 may be provided with one or more vacuum relief ports 41 with interior openings 42, providing for fluid communication between the interior volume 22 of the bottle 20 and the outside environment. As suggested above, the one or more vacuum relief ports 41 may each be operably associated with a check valve. In a more particular example, a check valve structure may be provided in the form of a flexible sealing gasket 30a.

Gasket 30a may be formed of or include a flexible, elastic, resilient material and have a first portion 31 effectively disposed so as to provide for sealing between fluid passage fitting 40 and neck 25 about the main opening, and a second portion 32 suitably sized, shaped and configured to cover the interior openings 42 of vacuum relief ports 41, as suggested in FIG. 13. As suggested in FIG. 14A, gasket 30a and/or second portion 32 thereof, may be configured to be flexible, and thereby flex inwardly (i.e., toward the interior volume 22) upon development of a vacuum within interior volume 22, and thereby allow ambient air to enter interior volume 22 through vacuum relief ports 41, as suggested by the dotted-line arrows in FIG. 14A. When the vacuum is relieved, the elasticity of the gasket material will cause it to return to its original position covering the openings 42, where it will prevent outflow of fluid through ports 41.

In some examples, the vacuum relief and/or an optional check valve system may be provided in a component(s) provided with the top fixture 100. The main body 101 of dispensing fixture 100 may be formed with a coupling cavity 112 to accommodate and retain in position a liquid outlet coupling 60. In some examples, the liquid outlet coupling 60 of the dispensing fixture 100 may be provided with one or more vacuum relief ports 67 having interior openings, as shown in FIG. 16B. When the top fixture 100 (shown in FIG. 15) is affixed to the bottle 20, the vacuum relief port 67 (shown in FIG. 16B) of liquid outlet coupling 60 may be in fluid communication with the interior openings 42 of the vacuum relief 41 port of the fluid passage fitting 40, providing fluid communication between the interior volume 22 of the bottle 20 and the outside environment. The one or more vacuum relief ports 67 of the liquid outlet coupling 60 may each be operably associated with a check valve 69, such as a duck bill valve, which may be disposed on top of the vacuum relief port 67.

A flexible sealing gasket 30b may be disposed on the bottom surface of the liquid outlet coupling 60, e.g., the bottom surface of the bending springs 61a of the liquid outlet coupling 60. The gasket 30b may be formed of or include a flexible, elastic, resilient material. When the dispensing fixture 100 is affixed to the bottle 20 (e.g., latch to the second retaining feature 29), a fluid seal may be formed between the rim 26 of the bottle 20 and the flexible sealing gasket 30b of the liquid outlet coupling 60. Preferably, in such embodiments, the fluid passage fitting 40 may be adapted to press/friction fit within the neck 25 and main opening of the bottle (rather than over the rim 26 of the bottle 20 as shown in FIG. 18), the fluid passage fitting 40 need not have a rim attachment structure 45, and/or the bottle 20 need not have a rim lip 27. The liquid outlet coupling 60 and fluid passage fitting 40 may be formed and adapted to cooperatively fit together upon assembly of the complete dispensing fixture onto the bottle 20, as reflected in FIG. 19B.

The liquid outlet coupling 60 may be provided with an O-ring 63 or any other suitable gasketing/sealing mechanism to cause it to have effectively sealed fluid communication and connection with fluid passage fitting 40, when the two are assembled together. Liquid outlet coupling 60 may have outlet passage 64 therethrough, continuing from an inlet opening out through an outlet bibb 62. The draw tube 47/liquid dispensing passage 43 may fluidly communicate with the outlet passage 64 of the liquid outlet coupling 60. The O-ring 63 or any other suitable gasketing/sealing mechanism of the liquid outlet coupling 60 may prevent fluid communication (either air or liquid composition) between the draw tube 47/liquid dispensing passage 43 and the interior openings 42 of the vacuum relief 41 port of the fluid passage fitting Preferably, the draw tube 47/liquid dispensing passage 43 only fluidly communicates with the outlet passage 64 of the liquid outlet coupling 60, when the dispensing fixture 100 is affixed to the bottle 20.

When the bottle 20 is capped, the interior openings 42 of the vacuum relief port 41 of the fluid passage fitting 40 may be in fluid communication with the draw tube 47/liquid dispensing passage 43. When the cap 50 is removed and the top fixture 100 is affixed to the bottle 20, the O-ring 63 (or any other suitable gasketing/sealing mechanism) of the liquid outlet coupling 60 forms a fluid seal with the interior wall of the coupling receptacle 40a of the fluid passage fitting thereby preventing fluid communication (either air or liquid composition) between the draw tube 47/liquid dispensing passage 43 and the interior openings 42 of the vacuum relief 41 port of the fluid passage fitting 40.

As discussed above, the liquid outlet coupling 60 of the dispensing fixture 100 may be provided with one or more vacuum relief ports 67 having interior openings. When the top fixture 100 is affixed to the bottle 20, the vacuum relief port 67 is in fluid communication with the interior openings 42 of the vacuum relief 41 port of the fluid passage fitting 40, providing fluid (air) communication between the interior volume 22 of the bottle 20 and the outside environment. As discussed above, the top fixture 100 may include a gasket 30b that forms a fluid seal with the rim 26 of the neck 25 of the bottle 20, when the top fixture 100 is affixed to the bottle 20. When the gasket 30b forms a fluid seal with the rim 26 of the neck 25 of the bottle 20, the interior openings 42 of the vacuum relief port 41 of the fluid passage fitting 40 are preferably only in fluid communication with the interior openings of the one or more vacuum relief ports 67. This may prevent or reduce leakage of the liquid composition out through the interior openings 42 of the vacuum relief port 41 of the fluid passage fitting 40.

It may be appreciated that the examples described and depicted provides a simple, effective and inexpensively manufactured vacuum relief system. The fluid passage fitting 40 may be formed of any suitable polymeric/plastic material such as polypropylene or HDPE. The sealing gasket 30a/30b may be formed of a suitably resilient and elastic polymeric or cellulose-based plastic material suitable for gasket sealing applications, such as, by way of non-limiting example, polyethylene foam, silicone rubber, other natural or synthetic rubbers, cork, pulp/cellulose-based materials, etc.

Referring to FIG. 14B, in other examples, a fluid passage fitting 40 may be configured (in some examples, with formed circumferential sealing fins, rings or ridges (not specifically shown) or an O-ring thereabout (not specifically shown)) to sealingly press-fit inside bottle neck 25, in the manner of a bottle stopper, without the need for a sealing gasket over the rim. In such examples, a vacuum relief port 41 may be provided through fitting 40, as noted above, separate from liquid dispensing passage 43. A check valve may be disposed and operably associated with vacuum relief port 41, such as a flap check valve 33, configured to allow fluid (e.g., air) to flow through port 41 into the bottle, but to prevent fluid from flowing out port 41. In such examples, the fluid passage fitting 40 may be held within the bottle neck by friction alone, or alternatively or supplementally, by an included rim attachment structure 45 (for example, as shown in FIG. 10A).

Additional Features of Dispensing Fixture and Assembly

Referring now to FIGS. 15-19, main body 101 of dispensing fixture 100 may be formed with a coupling cavity 112 to accommodate and retain in position a liquid outlet coupling 60. Liquid outlet coupling 60 and fluid passage fitting 40 may be formed and adapted to cooperatively fit together upon assembly of the complete dispensing fixture onto the bottle 20, as reflected in FIG. 19. Liquid outlet coupling 60 may be provided with an O-ring 63 or any other suitable gasketing/sealing mechanism to cause it to have effectively sealed fluid communication and connection with fluid passage fitting 40, when the two are assembled together. Liquid outlet coupling 60 may have outlet passage 64 therethrough, continuing from an inlet opening out through an outlet bibb 62. An outflow tube 65 may be fluidly connected to outlet bibb 62 and lead out of the main body 101 and thereby out of the dispensing fixture. As previously noted, outflow tube 65 may be, or may be fluidly connected with, a suitably convenient length of flexible tubing, leading and connecting to a spray wand. A draw tube 47 may be provided with the bottle and/or fluid passage fitting 40, and be fluidly connected to draw bibb 46 included on or as part of fluid passage fitting 40. Draw tube 47 is preferably of a length sufficient for a distal end thereof to reach to a location proximate the bottom of the interior volume 22 of the bottle 20, so as to be positioned to continue to draw liquid product from the bottle when liquid product has been depleted to a low level (i.e., so that substantially all of the liquid product supplied in the bottle may be drawn out by the system, for use). For purposes of providing vacuum relief to the bottle, for example, as described above, it may be desired that an airflow passage or cavity 102 be provided in the main body 101 between fluid passage fitting 40 and the outside environment, to allow fluid communication (i.e., air passageway) from the outside environment to the vacuum relief system.

Dispensing fixture 100 may be provided with a suspension system that allows liquid outlet coupling 60 to move slightly within and with respect to main body 101. This feature may be desired to accommodate imperfect fit between liquid outlet coupling 60 and fluid passage fitting 40, when the two are brought together, while still ensuring sealing via a sealing member such as O-ring 63. In some examples, the suspension system may include one or more coupling springs forming a part of or all of the suspension system, which holds liquid outlet coupling 60 within main body 101. In some examples, such coupling springs may have the form of bending springs 61a, configured to flex to allow coupling 60 to move upwardly and downwardly within main body 101. In some examples bending springs 61a may be integrally formed with coupling extending in a cantilever configuration, radially outwardly from the main portion of coupling to spring seats 109 formed in main body. (See FIG. 17.) In such configuration, there are preferably at least two such bending springs 61a radially oppositely disposed on coupling 60. In an alternative configurations, three or more bending springs 61a may be included, and may be disposed about coupling 60 at equal angles with respect to each other. Bending springs 61a are preferably discrete, and do not form a continuous body circumscribing the main portion of coupling 60. Providing a coupling 60 with a suspension system in the form of integrally formed bending spring members as described provides for cost-effective and efficient parts manufacturing, supply and assembly, in that no discrete, separate spring members need be included. The suspension system may also be configured to permit slight horizontal direction adjusting movement as well, to accommodate imperfect vertical alignment between coupling 60 and fluid passage fitting 40 and/or the main opening of bottle neck 25.

It may be appreciated that, in some examples, operable features and functions of fluid passage fitting 40 and liquid outlet coupling 60 might be combined in a single-piece component or unitized combination of parts forming a single component, which includes a fluid passageway and a separate vacuum release port therethrough, wherein the single component might be sealingly press-fit into the bottle neck upon placement of dispensing fixture 100 over neck 25. Where the liquid product provided in the bottle to be dispensed, however, is a product with which consumer-users may wish to minimize chances of hand or skin contact (such as the liquid product compositions identified and contemplated herein), a two-piece coupling system including separate fluid passage fitting 40 and liquid outlet coupling 60 as described herein may be preferred. This is because a separate fluid passage fitting 40 provided with a bottle filled with product may be provided with an included and pre-connected draw tube 47 (for example, as shown in FIG. 19), and the user will not need to make any conduit/fluid connections, either on the upstream side of dispensing fixture 100, on the downstream/outlet side of the dispensing fixture 100, other than bringing dispensing fixture 100 over bottle 20 and neck 25 and pushing it downwardly to latch it onto the bottle neck, as described herein.

It will be appreciated that the components of a dispensing fixture and bottle having the features described herein enable quick, simple and easy placement and latching of the dispensing fixture onto the bottle, and simultaneously and in the same single motion, establishment of a leak-free fluid connection providing access to liquid product in the bottle by a pump and product delivery system (examples described below), with provision of a vacuum relief system that allows ambient air to enter the bottle upon removal of liquid product from the bottle by the pump and delivery system.

It will be appreciated that for ease of manufacturing and assembly and effective fluid sealing, it may be preferable that cooperating features of components of the system including bottle neck 25, cap 50, bottle neck rim 26 and the main opening to bottle interior volume 22 defined thereby, fluid passage fitting 40, gasket 30a/30b, and portions of liquid outlet coupling adapted to cooperatively fit with fluid passage fitting 40 and or the main opening to bottle interior volume 22 defined by the rim 26, have cross sections and/or inner and/or outer profiles that are substantially circular, when viewed along a direction orthogonal to the plane 26p along which rim 26 lies.

However, it may be further appreciated that for purposes of efficient utilization of space in packing and shipping multiple packages, and efficient utilization of shelving space, a main portion of bottle 22 may be imparted with a horizontal outer profile having a shape that accommodates close horizontal spacing of adjacent packages and efficient utilization of space, with respect to a ratio of volume of liquid product provided, to shipping or storage space utilized by multiple packages shipped or stored. Thus, it may be desired that bottle 22 be imparted with a horizontal outer profile shape that is non-circular, and has two or more sides that are substantially straight to provide for efficient horizontal space utilization, e.g., square, rounded square, rectangle, rounded rectangle, stadium-shape, triangle, rounded triangle, hexagon, rounded hexagon, etc., when a plurality of bottles/packages are shipped or stored in close proximity with each other.

Trigger Spray Dispenser Configuration

The dispensing system may be provided with a trigger spray dispenser 500 (see, e.g., FIGS. 34A-34G). The trigger spray dispenser 500 may be fluidly connected to the dispensing fixture 100 via a suitably convenient length of flexible outflow tube 65.

The trigger spray dispenser 500 may include or be operably fluidly connected with a pump configured to draw and drive liquid product from the interior volume 22 of bottle 20, through the dispensing fixture 100, out through outflow tube 65, through the trigger spray dispenser and out nozzle 504, for delivery to a desired application site.

In some examples, the pump may be a manually operated, manually driven pump, similar in operation to known spray/trigger pumps found on many household products.

In some examples, the pump may be an electromechanical device including an electric motor driving a liquid pump mechanism. In some examples, the liquid pump mechanism may be a gear or lobe pump, which may be preferred for applications contemplated herein, where simplicity, adaptability to small size/compactness, pulse-free fluid delivery and relatively robust pressure development relative to size are desired, for purposes of enabling thorough dispersion of liquid product through a spray nozzle for efficient uniform application of product to application sites, without a need for a large motor or large electrical energy input. In some examples, the electromechanical pump with a gear pump driven by an electric motor, may be powered by one or more batteries housed within the housing 502 of the trigger spray dispenser 500. For consumer convenience the pump may be configured to operate for a relatively lengthy period of time, e.g., sufficient to completely drain the liquid content from at least one filled bottle, more preferably at least two bottles, and still more preferably at least three bottles, on power supplied by commercially available, consumer-grade, replaceable batteries. In other examples the battery(ies) may be of the rechargeable type such as found in many types of consumer products, consumer electronic devices, small appliances, cordless tools, etc.

The trigger spray dispenser 500 may include a housing 502 and a handle 508, imparted with any shape deemed suitable for purposes of ergonomic gripping and actuating by the user, with one hand, while having suitable internal space and configuration to suitably house and hold in position operable internal components. The trigger spray dispenser 500 may include a trigger spray actuator 506, with operable components included therewith to effectuate activation of a pump, to pump liquid product through the wand.

Suitable trigger spray dispensers are disclosed in U.S. Pat. No. 6,367,665 and available from Silgan Dispensing under the Mixor® HP tradename.

Wand Configuration, Activation and Locking Features

The dispensing system may be provided with a spray wand 300 (see, e.g., FIG. 1). Spray wand 300 may be fluidly connected to the dispensing fixture 100 via a suitably convenient length of flexible outflow tube 65.

Spray wand 300 may include or be operably fluidly connected with a pump configured to draw and drive liquid product from the interior volume 22 of bottle 20, through the dispensing fixture 100, out through outflow tube 65, through wand 300, out through spray tube 305 (see FIGS. 2 and 26), and out nozzle 310, for delivery to a desired application site.

In some examples, the pump may be a manually operated, manually driven pump, similar in operation to known spray/trigger pumps found on many household products.

In some examples, the pump may be an electromechanical device including an electric motor driving a liquid pump mechanism. In some examples, the liquid pump mechanism may be a gear or lobe pump, which may be preferred for applications contemplated herein, where simplicity, adaptability to small size/compactness, pulse-free fluid delivery and relatively robust pressure development relative to size are desired, for purposes of enabling thorough dispersion of liquid product through a spray nozzle for efficient uniform application of product to application sites, without a need for a large motor or large electrical energy input. In some examples, the electromechanical pump with a gear pump driven by an electric motor, may be powered by one or more batteries housed within a housing 300a of wand 300. For consumer convenience the pump may be configured to operate for a relatively lengthy period of time, e.g., sufficient to completely drain the liquid content from at least one filled bottle, more preferably at least two bottles, and still more preferably at least three bottles, on power supplied by commercially available, consumer-grade, replaceable batteries. In other examples the battery(ies) may be of the rechargeable type such as found in many types of consumer products, consumer electronic devices, small appliances, cordless tools, etc.

Referring now to FIGS. 20-27, a spray wand 300 may include a housing 300a, imparted with any shape deemed suitable for purposes of ergonomic gripping and actuating by the user, with one hand, while having suitable internal space and configuration to suitably house and hold in position operable internal components. Wand 300 may include a spray trigger or switch 320, with operable components included therewith to effectuate activation of a pump, to pump liquid product through the wand.

The wand 300 may include a receiving bibb 303a to be fluidly connected to an outflow tube 65 (see e.g., FIGS. 2, 24), and an exit bibb (303b) to be fluidly connected to a spray nozzle 310, in some examples, via a relatively rigid spray tube 305 (see e.g., FIGS. 2, 27).

In some examples, wand 300 may include a discrete lock switch 321, accessible to the user and operable via a mechanism within the housing to alternately allow or prevent actuation of spray trigger 320, or otherwise operable to alternately allow or prevent activation of the pump. In some examples lock switch 321 may be a sliding switch, slidable between a locking position 322b and an unlocking position 322a. In some examples (not specifically shown), locking and unlocking functions, respectively, may be mechanically linked, within housing 300a, to positioning of exit bibb 303b and/or exit fitting 303c in folded/stowed and extended/deployed positions, respectively (the respective positions are illustrated in FIGS. 26 and 27).

In some particular examples, the pump activation and locking functions may be provided by components schematically illustrated in FIGS. 22A and 23 (or alternatively FIG. 22B) which may be securely fitted and held in position within handle housing 300a.

FIG. 22A illustrates a non-limiting example of a configuration of components in a locked, pump-deactivated configuration. A valve 335, for example, a spool valve, having an axially sliding stem actuator 336 may be blocked in a closed configuration by direct or indirect mechanical communication with a lock switch 321, which may be configured to slide within the handle, disposed in a locking position within a lock switch track 322 formed in the housing. On the other end of the valve, valve stem actuator 336 blocks inward movement or depression of spray trigger 320, which may be configured to otherwise pivot inwardly into the wand housing about trigger pivot 323, within a trigger track 324 formed in the housing. Trigger 320 is mechanically linked to pump power switch 340 and prevented by the blocked valve stem actuator 336 from closing switch 340, and thereby prevented from causing electrical current to flow from a power source 342 to pump 330, through power supply line 343 (as previously suggested, power source 342 may be a battery or batteries). Thus, in the configuration schematically shown in FIG. 22A, valve 335 is closed, switch 340 is open, and pump 330 is deactivated, and liquid product will not pass through the wand, i.e. from inflow conduit 302a to outflow conduit 302b. In some examples, valve stem actuator 336 and/or spray trigger 320 and/or power switch 340 may be spring-biased in valve-closed, switch-open and/or un-activated positions as illustrated, by way of example, in FIG. 22A.

In some examples, such as schematically illustrated in FIG. 22B, a valving system may be simplified. Rather than having a user-operated valve such as illustrated in FIG. 22A, the system may include, for example, a simplified, automatic valve 335c. Automatic valve 335c may be configured fluidly in line with inflow conduit 302a, pump 330, and outflow conduit 302b. In some examples, automatic valve 335c may be a check valve configured to permit flow out and prevent backward/inflow, having a cracking pressure that is high enough to prevent the system from leaking liquid product via gravity or syphoning outflow during storage or otherwise when pump 330 is not activated, but low enough such that the valve may be forced open to allow outflow in response to pressure generated by pump 330 when activated. In some examples, automatic valve 335c may be a solenoid valve that is configured to open when pump 330 is connected to a power supply, e.g., via power switch 340. In such examples, a lock switch 321 preventing actuation of spray trigger 320 may be configured in direct or indirect operable mechanical communication with spray trigger via, e.g., linkage 337.

FIG. 23 illustrates the components shown in FIG. 22A in an unlocked, pump-activated configuration. Stem actuator 336 of valve 335 is permitted to slide to an open configuration when sliding lock switch 321 is disposed in an unlocking position within a lock switch track 322 formed in the housing. On the other end of the valve, because valve stem actuator 336 is not blocked by lock switch 321, it may be moved to a valve-open position via inward movement or depression of spray trigger 320. Trigger 320, being mechanically linked to pump power switch 340 and now free to be depressed, upon depression causes pump power switch 340 to be closed to allow current to flow from power source 342 to pump 330. Liquid product may now flow and pass through valve 335 from inflow conduit 302a to and out from outflow conduit 302b, being drawn and driven by operation of pump 330.

The configurations of components and combinations thereof described above enables a compact, easy-to-use, ergonomic, efficient and effective system, for preventing unwanted drawing or leakage and discharge of liquid product from wand 300, and alternately, triggering pumping and discharge of liquid product to, through and from wand 300. The components of the wand system may be cost effectively produced, procured and assembled.

Now referring to FIGS. 24 and 25, the bottle 20 or dispensing fixture 100 may be provided with a wand stowing fixture 350, which may be affixed to the bottle and/or the dispensing fixture by any suitable mechanism, or may be formed as part thereof. Wand stowing fixture 350 may be configured to hold wand 300 in its folded/stowed configuration (examples illustrated in FIGS. 2 and 26), at a suitable height such that no portion of the wand in its lowest-most stowed position lies below the bottom surface of bottle 20 (i.e., such that wand 300 in folded/stowed configuration will not interfere with or contact the surface upon which the bottle and package are to be stowed/stored.

Where a lock switch 321 is provided with wand 300, wand stowing fixture 350 may be provided with a lock switch engagement feature 351, configured to engage lock switch 321 upon stowing of wand 300 in or on stowing fixture 350, and move lock switch 321 to its locking position as the wand is placed in the stowed position in the stowing fixture.

As noted, in some examples, wand 300 may be configured such that it may be alternately placed in an extended/deployed configuration as suggested in FIG. 27, and alternately, in a folded/stowed configuration as suggested in FIG. 26. A folded/stowed configuration may be desired for purposes of more compact shipping/transport, retail display, and storage, and to protect the wand 300 and spray tube 305 from damage or separation from the system when not in use.

To enable such alternate configurations, wand 300 may be provided with a pivoting exit fitting 303c, which pivots about an axis 400 of one or a pair of pivot pins 304a that are seated at their outside ends within housing 300a. Referring to FIGS. 26, 27 and 28A-28C, exit fitting 303c may include, integrally, or by assembly, exit bibb 303b. Spray tube 305 may be fluidly connected to discharge end 303d of exit bibb 303b, and a flexible outflow conduit 302b (which may be disposed inside handle housing 300a) may be fluidly connected to receiving end 303r of exit bibb 303b. The exit fitting 303c may be configured such that a flexible outflow conduit 302b will flex and move across and back over pivot pin axis 400 as the wand is alternately placed in folded/stowed (e.g., FIG. 26) and extended/deployed (e.g. FIG. 27) configurations. Exit fitting 303c may include one or two conduit guides 304b that define a guide channel 304c in which outflow conduit 302b is constrained to flex substantially only along a plane that is orthogonal to pivot pin axis 400. This arrangement allows wand 300 to be constructed using relatively less internal conduit tubing, arranged in a relatively simpler configuration within wand housing 300a, than some current systems that provide for such folding/stowing configurations but require routing an outflow conduit around a pivot axis. Exit fitting 303c and housing 300a may be provided with a suitable latching or detent mechanism (not specifically shown) that releasably holds wand 300 in the respective alternate folded/stowed and extended/deployed configurations. In some examples exit fitting 303c may include conduit guide(s) 304b and exit bibb 303b in a single, integrally formed body; in other examples these components may be separately formed and joined together in any suitable manner to be made functionally unitary.

Nozzle Use Guide

In some examples, the system described herein is contemplated for use in applying liquid leaf surface active herbicide composition to application sites, e.g., leaves of weeds. Such compositions are typically formulated to be effective when applied to leaves; they do not work as designed when applied to lower stems or soil about weed roots, or to the roots themselves. It has been learned, however, that some consumer-users may attempt apply such liquid products by forcing the spray nozzle downwardly into the stems where they emerge from the soil, or into the soil itself, acting under a mistaken belief that such application is effective.

Referring to FIG. 29, many current spray wands include a bullet-shaped, capsule-shaped or otherwise tapered-end nozzle 310 at the sprayer end 309, which users may perceive to be effective for “injecting” liquid product into or about weed stems or roots, or into the soil about the roots. Some nozzle designs may further encourage this behavior by having designs that emit a consolidated stream rather, or as an alternative option to, a dispersed spray.

To disincentivize and discourage this practice, and to convey an implied message that leaf surface application is required for designed efficacy of a liquid leaf surface active herbicide composition product provided with the system, the sprayer end 309 may be reconfigured.

A physical nozzle use guide may be included with the wand. Referring to FIGS. 30-32, a spray wand may terminate in a distal spray nozzle 310, which is configured to emit a dispersed spray of liquid product delivered under pressure through spray tube 305. For a liquid leaf surface active herbicide composition, it may be desired that the spray nozzle 310 not be configured to emit a consolidated stream. Spray tube 305 will have a largest dimension or outer diameter TD. It has been learned that if nozzle 310 is accompanied and surrounded by a nozzle end structure 311 having a largest radial dimension SD, proximate the distal end of the wand, that is at least 150 percent the spray tube outer diameter TD, more preferably at least 200 percent the spray tube outer diameter TD, and even more preferably at least 300 percent the spray tube outer diameter TD, the nozzle end structure 311 will be effective for discouraging attempts to force the nozzle into the soil or to attempt to “inject” liquid product. Further, the shape of the nozzle may be fashioned to implicitly suggest that a dispersed spray pattern suited to efficient application of liquid product over exposed broad (i.e., leaf) surfaces is intended by the manufacturer. To further these purposes, the nozzle end structure may be flared outwardly toward its distal end, as suggested in the figures. The nozzle end structure may have the form of a shroud, or a cage or guard structure, or any suitable structure configured to allow a dispersed spray to pass from the nozzle without obstruction from the distal end, but frustrate attempts to force the end structure into ground/soil.

Liquid Composition

The liquid dispensing system as contemplated herein may dispense a liquid composition that is intended to be sprayed onto a target surface and/or in a target area. Non-limiting examples of liquid compositions include home care compositions, such as hard floor cleaners and conditioners, carpet cleaners and conditioners, carpet deodorizers, carpet spot cleaners, window cleaners, fabric refreshing sprays (e.g., for clothing or furniture), hard surface cleaners (e.g., for dishware, sinks, countertops), and air fresheners; car care compositions, such as upholstery cleaners and conditioners, hard surface cleaners, leather cleaners, carpet cleaners, tire cleaners, and automotive glass cleaners; pest control compositions, such as herbicides, insecticides, insect barrier products, and garden insecticides. The liquid composition may be suitable for consumer, commercial, and/or institutional use. The liquid composition may be housed within the bottle 20. The bottle may store from about 800 g to about 2000 g, or from about 1000 g to about 2000 g, or from about 1400 g to about 1900 g, of the liquid composition.

The liquid composition may have a Brookfield viscosity from about 1 cps to about 300 cps, or from about 1 cps to about 200 cps, or from about 2 cps to about 100 cps, or from about 3 cps to about 50 cps, as measured according to the method described herein. The Brookfield viscosity may enable the liquid dispensing system to dispense the composition as droplets. For some products, such as pesticide products, droplets may be preferred, particularly versus a mist, a stream, or a foam. The liquid composition may have a surface tension from about 15 mN/m to about 50 mN/m, or from about 18 mN/m to about 40 mN/m, or from about 20 mN/m to about 30 mN/m, or from about 22 mN/m to about 28 mN/m, as measured according to the method described herein. It is believed that droplets may be preferred for delivering a targeted spray, while also sufficiently covering a target area.

The liquid composition may comprise particles having an intensity mean particle size of from about 2 nm to about 500 nm, alternatively from about 4 nm to about 400 nm, alternatively from about 5 nm to about 100 nm. The liquid composition may comprise particles having an intensity mean particle size of less than about 1 micron, preferably less than about 500 nm. Mean intensity particle size can be measured according to the Particle Size Test Method described hereafter.

The liquid composition may comprise particles having a volume mean particle size ranging from about 1 nm to about 100 nm, or from about 2 nm to about 50 nm, or from about 2 nm to about nm, or from about 2 nm to about 10 nm. The liquid composition may comprise particles having a volume mean particle size of less than about 1 micron, preferably less than about 500 nm. Mean volume particle size can be measured according to the Particle Size Test Method described hereafter. Volume mean particle size may be selected to provide a transparent or translucent liquid composition, as well as to efficiently deliver an active agent to the target surface or area.

As detailed below, in the Spray Droplet Size Test Method spray droplet volume size distribution measurements comprising Spray D(50) Normalized, Spray D(90) Normalized, and Spray D(2,3) Normalized values are determined using a Malvern Spraytec 2000 laser diffraction spray droplet sizing instrument (supplied by Malvern Instruments, Worcestershire, UK). The liquid composition, when dispensed through the liquid dispensing system, may have a Spray D(90) ranging from about 100 microns to 900 microns, or from about 125 microns to about 800 microns, or from about 150 microns to about 700 microns. Spray D(90) may be selected to efficiently deliver an active agent to the target surface or area. Also, a Spray D(90) in the disclosed ranges may be perceived as capable of traveling a distance of one or more meters and depositing on a target surface or in a target area. Particles having a Spray D(90) less than 100 microns may create a spray that is too misty or a spray that does not have sufficient velocity to travel to a target surface or area.

The liquid composition may have a NTU value less than about 200, or less than about 100 or from about 0.5 to about 50, or from about 1 to about 25, as measured according to the Turbidity method described herein. A liquid composition having a NTU value in the disclosed ranges may be perceived by a consumer as being clear, transparent, or translucent, which may connote purity, quality, and/or that the composition is not likely to stain surfaces.

The liquid composition may have a b* value form about 0 to about 5, or from about 0.01 to about 4, or from about 0.05 to about 3.5, or from about 0.1 to about 3, as measured according to the method described herein. A liquid composition with a b* value according to the disclosed ranges may be perceived by a consumer as having a colorless appearance, while b* values outside the disclosed ranges, especially b* values greater than 5, may appear yellow to a consumer, which may connote that the composition contains impurities, has degraded, and/or is unsuitable for use.

The liquid dispensing system may have a spray rate ranging from about 0.5 g/s to about 5 g/s, or from about 0.75 g/s to about 4 g/s, or from about 1.25 g/s to about 3.5 g/s, or from about 1.5 g/s to about 3 g/s. The spray rate may be selected to enable targeted dispensing and delivery of the liquid composition from the liquid dispensing system, without over-spraying or spraying composition outside the target area.

Preferably, the liquid composition is a pest control composition. Pest control products and compositions may include products and compositions for managing a pest species inside and outside of a building, such as a dwelling or a business, including, but not limited to, areas such as garages, patios, balconies, screened porches, lawns, and/or gardens. Pest control products and compositions may include products and compositions for use in and/or on yards, lawns, bushes, trees, and/or outdoor plants, as well as for use on or around indoor plants. Pest control products and compositions may include selective and non-selective products and compositions, such as selective and non-selective herbicides, fungicides, and insecticides. Pest control products and compositions may also include products and compositions for topical application to humans to control or repel pest species, such as insects and other arthropods.

In particular, the market for weed control products and arthropod pest control products is growing, due to factors such as an increase in urban housing, changes in weather patterns, and an increase in home food gardening and the desire to keep lawns, flower beds, etc. looking neat and attractive. At the same time, there is increasing consumer demand for insecticide and herbicide products that are natural and non-toxic. Consumers also prefer herbicide and insecticide products that contain a limited number of ingredients and/or recognizable ingredients, as communicated by simpler ingredient statements. However, these products are still expected to be efficacious and efficiently control weeds and arthropods, comparable to traditional chemical pesticide products. Also, there are existing herbicide and insecticide products that contain natural ingredients, such as plant essential oils. However, these existing products have a number of disadvantages: some products are messy or difficult to use and some products have limited efficacy.

The liquid pest control composition may be oil-based and may comprise at least one carrier oil. The carrier oil may be a hydrocarbon oil, such as a hydrocarbon oil derived from petroleum, animal, or plant sources. An example of a suitable petroleum-derived oil is mineral oil. An example of a suitable animal-derived oil includes fish oil. Examples of suitable plant-derived oils include corn oil, soybean oil, palm oil, rapeseed oil, sesame oil, wheat oil, wheat germ oil, coconut oil, canola oil, sunflower oil, safflower oil, peanut oil, olive oil, and castor oil. The hydrocarbon oil may be paraffinic, naphthenic and/or aromatic. The liquid pest control composition may comprise a single carrier oil or a mixture of carrier oils. The liquid pest control composition may comprise greater than about 25 percent by weight of a carrier oil, or from about 30% by weight to about 99.5% by weight of a carrier oil, or from about 50% by weight to about 98% by weight of a carrier oil, or from about 80% by weight to about 95% by weight of a carrier oil or from about 85% by weight to about 95% by weight of a carrier oil. Liquid pest control compositions comprising carrier oils are described in US Pat. Pub. No. 2021/0169061A1, which is hereby incorporated by reference herein.

Alternatively, the liquid pest control compositions may be substantially free of a geologically derived (e.g., petroleum-based) carrier oils, such as mineral oil, as products containing a carrier oil may be messy to use and may leave a residue on a treated surface.

The liquid pest control compositions may comprise from about 40% to about 99% by weight of the composition of water. Such liquid pest control compositions comprising water are described in U.S. application Ser. No. 17/865,943, U.S. application Ser. No. 18/082,891, U.S. application Ser. No. 18/334,004, and U.S. Provisional App. Ser. Nos. 63/509,339 and 63/509,380, all of which are hereby incorporated by reference herein.

Suitable liquid herbicide compositions may also comprise from about 40% to about 99% by weight of the composition of water and are described in WO App. Ser. No. PCT/US23/68554 and U.S. Provisional App. Ser. No. 63/355,134, which are hereby incorporated by reference herein.

The pest control compositions of the present disclosure may comprise renewable components. The compositions disclosed herein may comprise from about 1%, or from about 5%, or from about 10%, or from about 20% or from about 30%, of from about 40% or from about 50%, to about 40%, or to about 50%, or to about 60% or to about 70% or to about 80% or to about 90%, or to about 100% by weight of renewable components. The compositions disclosed herein may be at least partially or fully bio-based, As such, the composition can comprise a bio-based carbon content of about 50% to about 100%, preferably about 70% to about 100%, more preferably about 75% to about 100%, even more preferably about 80% to about 100%, most preferably about 90% to about 100%.

The GRAS ingredient may also include, but is not limited to, agents that are generally recognized, among experts qualified by scientific training and experience to evaluate their safety, as having been adequately shown through scientific procedures (or, in the case of a substance used in food prior to Jan. 1, 1958, through either scientific procedures or through experience based on common use in food) to be safe. The use of food grade or GRAS ingredients enables the compositions disclosed herein to be used by consumers without rinsing a treated surface after use. The compositions disclosed herein may comprise ingredients that have a tolerance or tolerance exemption for use on food contact surfaces under the Federal Food, Drug, and Cosmetic Act US law (see, e.g., 40 CFR 180, November 2016, December 2015 update).

Active Ingredients

The liquid pest control composition may comprise one or more active ingredients (also referred to herein as actives). The liquid pest control composition may comprise from about to about 30%, or from about 0.05% to about 25%, or from about 0.15% to about 20%, or from about 0.5% to about 15%, or from about 1% to about 12%, or from about 2% to about 10%, by weight of the composition of one or more active ingredients.

Surfactant

The liquid pest control composition disclosed herein may be formulated with one or more surfactants. The liquid pest control composition may comprise from about 0.01% to about 15%, or from about 0.1% to about 10%, or from about 1% to about 10%, or from about 1% to about 12.5%, or from about 1% to about 15%, or from about 1% to about 8% of one or more surfactants, preferably one or more anionic surfactants, more preferably sodium lauryl sulfate.

A sprayed drop of a liquid pesticidal composition comprising an active agent is preferably able to wet a target surface and spread out or cover a target area to perform its intended function. A surfactant generally reduces the surface tension of the water on the surface of the spray drop by reducing the interfacial tension between the spray drop and target surface, e.g., exoskeleton of an arthropod. Surfactants also wet and disperse particles of active ingredient(s) in the composition prior to spraying, thereby enabling more uniform coverage and wetting of the target upon spraying. Surfactants may also function to emulsify active agents that are not easily solubilized in water, such as oils. Surfactants thus include various agents known to function as emulsifiers or wetting agents. Suitable surfactants include anionic surfactants, amphoteric surfactants, zwitterionic surfactants, nonionic surfactants, cationic surfactants, or mixtures thereof.

Anionic surfactants are surfactant compounds that contain a long chain hydrocarbon hydrophobic group in their molecular structure and a hydrophilic group, including salts such as carboxylate, sulfonate, sulfate or phosphate groups. The salts may be sodium, potassium, calcium, magnesium, barium, iron, ammonium and amine salts of such surfactants. Anionic surfactants include the alkali metal, ammonium and alkanol ammonium salts of organic sulfuric reaction products having in their molecular structure an alkyl or alkaryl group containing from about 8 to about 22 carbon atoms and a sulfonic or sulfuric acid ester group. Examples of such anionic surfactants include water soluble salts and mixtures of salts of alkyl benzene sulfonates having from about 8 to about 22 carbon atoms in the allyl group (e.g., linear alkyl benzene sulfonates, such as dodecylbenzene sulfonate and salts thereof), alkyl sulfates and alkali metal salts thereof (preferably those having from about 8 to about 22 carbon atoms in the alkyl group, e.g., sodium dodecyl/lauryl sulfate), alkyl ether sulfates having from about 8 to about 22 carbon atoms in the alkyl group and about 2 to about 9 moles of ethylene oxide (e.g., sodium laureth sulfate). Aryl groups generally include one or two rings, alkyl groups generally include from about 8 to about 22 carbon atoms, and ether groups generally comprise from about 1 to about 9 moles of ethylene oxide (EO) and/or propylene oxide (PO), preferably EO. A preferred anionic surfactant is sodium lauryl sulfate or SLS (also known as sodium dodecyl sulfate). The liquid pest control composition may comprise from about 1% to about 10%, preferably from about 2% to about 8.5%, or from about 4% to about 8%, by weight of the composition of sodium lauryl sulfate.

Anionic surfactants also include fatty acids and salts thereof. Fatty acids and salts thereof are organic molecules comprising a single carboxylic acid moiety (carboxylate anion in salts) and at least 7 carbon atoms, or from about 11 to about 22 carbon atoms, or from about 12 to about 16 carbon atoms. The salts may be sodium, potassium, calcium, magnesium, barium, iron, ammonium and amine salts of fatty acids. The salts of fatty acids are also known as soaps. Fatty acid and the salts thereof may be linear, branched, saturated, unsaturated, cyclic, or mixtures thereof. Nonlimiting examples of fatty acids and salts thereof include octanoic acid, nonanoic acid, decanoic acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, lignoceric acid, myristoleic acid, palmitoleic acid, sapienic acid, oleic acid, elaidic acid, vaccenic acid, linoleic acid, linoelaidic acid, arachidonic acid, eicosapentaenoic acid, erucic acid, docosahexaenoic acid, the sodium, calcium, potassium or zinc salts thereof, or mixtures thereof.

Alternatively, the liquid pest control compositions may be substantially free of fatty acids, as a fatty acid may be difficult to solubilize in an aqueous composition. In particular, the liquid compositions may be substantially free of lauric acid, oleic acid, stearic acid, or a combination thereof.

Additional suitable anionic surfactants include alkyl sulfosuccinates, alkyl ether sulfosuccinates, olefin sulfonates, alkyl sarcosinates, alkyl monoglyceride sulfates and ether sulfates, alkyl ether carboxylates, paraffinic sulfonates, acyl methyl taurates, sulfoacetates, acyl lactates, and sulfosuccinamides.

Amphoteric surfactants are surface active agents containing at least one anionic group and at least one cationic group and may act as either acids or bases, depending on pH. Some of these compounds are aliphatic derivatives of heterocyclic secondary and tertiary amines, in which the aliphatic substituent(s) may be straight or branched, at least one of the aliphatic substituents contains from about 6 to about 20, or from about 8 to about 18, carbon atoms, and at least one of the aliphatic substituents contains an anionic water-solubilizing group, e.g., carboxy, phosphonate, phosphate, sulfonate, sulfate.

Zwitterionic surfactants are surface active agents having a positive and negative charge in the same molecule, where the molecule is zwitterionic at all pHs. Zwitterionic surfactants include betaines, sultaines, and lecithins. The zwitterionic surfactants generally contain a quaternary ammonium, quaternary phosphonium, or a tertiary sulfonium moiety. Zwitterionic surfactants contain at least one straight chain or branched aliphatic substituent, which contains from about 6 to 20, or from about 8 to about 18, carbon atoms, and at least one aliphatic substituent containing an anionic water-solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate or phosphonate.

Examples of suitable amphoteric and zwitterionic surfactants include the alkali metal, alkaline earth metal, ammonium or substituted ammonium salts of alkyl amphocarboxyglycinates and alkyl amphocarboxypropionates, alkyl amphodipropionates, alkyl monoacetate, alkyl diacetates, alkyl amphoglycinates, and alkyl amphopropionates, where the alkyl group has from 6 to about 20 carbon atoms. Other suitable amphoteric and zwitterionic surfactants include alkyliminomonoacetates, alkyliminidiacetates, alkyliminopropionates, alkyliminidipropionates, and alkylamphopropylsulfonates, where the alkyl group has from about 12 to about 18 carbon atoms, as well as alkyl betaines, alkylamidoalkylene betaines, alklyl sultaines, and alkylamidoalkylenehydroxy sulfonates.

The nonionic surfactant(s) may be any of the known nonionic surfactants, examples of which include condensates of ethylene oxide with a hydrophobic moiety. Nonionic surfactants include ethoxylated primary or secondary aliphatic alcohols having from about 8 to about 24 carbon atoms, in either straight or branch chain configuration, with from about 2 to about 40, or from about 2 and about 9 moles of ethylene oxide per mole of alcohol. Other suitable nonionic surfactants include the condensation products of alkyl phenols having from about 6 to about 12 carbon atoms with about 3 to about 100, or 3 to about 60, or 3 to about 30, or about 5 to about 14 moles of ethylene oxide. Nonionic surfactants also include ethoxylated castor oils and silicone surfactants, such as Silwet L-8610, Silwet L-8600, Silwet L-77, Silwet L-7657, Silwet L-7650, Silwet L-7607, Silwet L-7604, Silwet L-7600, and Silwet L-7280. Nonionic surfactants also include glyceryl esters, such as polyglyceryl oleate/stearate.

The liquid pest control compositions of the present disclosure may optionally comprise one or more cationic surfactants. Suitable cationic surfactants include quaternary ammonium surfactants and amino surfactants that are positively charged at the pH of the liquid pest control composition.

The weight ratio of surfactant, preferably anionic surfactant, more preferably sodium lauryl sulfate, to active ingredient may be from about 1:3 to about 30:1, or about 1:3 to about or about 1:1 to about 20:1, or about 1:1 to about 10:1, or about 1:3 to about 3:1, or about 1:2 to about 2:1, or about 1:1.5 to about 1.5:1, or about 1:1.2 to about 1.2:1. The weight ratio of surfactant, preferably anionic surfactant, more preferably sodium lauryl sulfate, to lemongrass oil may be about 1:1 to about 30:1 or about 2:1 to about 30:1. The weight ratio of surfactant, preferably anionic surfactant, more preferably sodium lauryl sulfate, to active ingredient, preferably an essential oil or a constituent thereof, may be from about 1:1 to about 30:1 or about 1:1 to about 20:1.

Spray Droplet Size Test Method

The term “Dv10 value” describes the average particle size where 10 vol. % of the particles have a smaller size. Similarly, the term “Dv50 value” describes the average particle size where 50 vol. % of the particles have a smaller size, and the term “Dv90 value” describes the average particle size where 90 vol. % of the particles have a smaller size. The Sauter mean diameter (D[3, 2]) is the weighted average surface diameter, assuming spherical particles of the same surface area as the actual particles:

$D\left[3,2\right]=\frac{\sum D_i^3{n}_i}{\sum D_i^2{n}_i}.$

Spray droplet volume size distribution measurements comprising Spray D(50) Normalized, Spray D(90) Normalized, and Spray D(2,3) Normalized values are determined using a Malvern Spraytec 2000 laser diffraction spray droplet sizing instrument (supplied by Malvern Instruments, Worcestershire, UK), equipped with a 300 mm lens possessing a focal length of the 150 mm, and an Air Purge System (not greater than 14.5 psi). The system is controlled with a computer and software accompanying the instrument, such as the Spraytec software version 3.20 or equivalent, utilizing Mie Theory and Fraunhofer Approximation optical theory. The system is placed in a fume hood for atmospheric control with care taken to place it directly opposite the actuation spray plume trajectory to prevent saturation, with an air flow rate of between 50-70 L/min (60 L/min was the target rate). The distance from the dispensing nozzle orifice to the laser during measurements is 30 cm. A new spray bottle is used for each sample replicate analyzed. Lighting conditions are not changed during or between the background control and test sample data collection periods. Light obscuration values below 95% are considered suitable to provide accurate results.

Samples analyzed included “example” samples, which are samples according to this disclosure, and comparative samples. All newly created example samples are tested within three hours of preparation and are measured at temperatures between 20-22° C. Deionized water is used as a standard reference spray and is labeled as the “control.”

On the Output tab, Export Option is set to “not selected”, the Derived Parameter is selected, the Use Averaging Period box is selected and set to “0.0” and “ms”. On the Average menu “Average scatter data” is selected.

Spray measurements are conducted using the following Spray Procedure: The sample is first test sprayed from the spray bottle for 1-2 seconds, to ensure that the nozzle is free flowing and not clogged; the sample is loaded into the holding device in the front of the Spraytec 2000 system. The actuator is fully depressed. The spray droplet size data are viewed and saved as “Average Scatter Data”.

a. The value obtained from each sample measurement is normalized to the control sample value in accordance with the following calculations:

The value of Spray D(50) Normalized=D(50)_Example/D(50)_Control;

The value of Spray D(90) Normalized=D(90)_Example/D(90)_Control;

The value of Spray D(3,2) Normalized=D(3,2)_Example/D(3,2)_controi;

• • wherein:
  • Spray D(50), Spray D(90), and Spray D(3,2) are values obtained from the instrument software for both the example samples and control samples separately.

Each of the Spray D(90) Normalized and Spray D(3,2) Normalized values reported for each of the samples is the average value calculated from five replicate spray plumes per sample.

Determination of the Hunter L.a.b. (CIE) b* Value

The formation of yellow color is measured using the Hunter L.a.b. (CIE) method. The b* value is determined using a HunterLab ColorFlex EZ® spectrophotometer (HunterLab, 11491 Sunset Hills Road, Reston, Virginia 20190). The methodology that is used is described in detail in the “User's Manual for ColorFlex EZ Version 2.2.”

The HunterLab ColorFlex EZ® spectrophotometer uses a xenon flash lamp to illuminate a sample. The light reflected from the sample is then separated into its component wavelengths through a dispersion grating. The relative intensities of the light at different wavelengths along the visible spectrum (400-700 nm) are then analyzed to produce a number result indicative of the color of the sample.

Turbidity Method

A turbidimeter is used to measure the turbidity of the compositions. This instrument measures the turbidity of liquids in Nephelometric Turbidity Units (NTU). The method of measuring turbidity is described in detail in the following reference: Hach 2100Q and 2100Qis User Manual, Edition 6, 08/2021, from the Hach Company. If a sample is not homogenous prior to analysis, the sample is inverted until it appears homogenous and is then poured into an analyte vile for measurement.

This method of measurement determines quantitative values of turbidity by evaluating the ratio of a primary nephelometric light scatter signal to a transmitted light scatter signal. This particular method of evaluation provides values between 0-1000 NTU, where increasing NTU values indicate more turbid compositions. In between each test sample, water controls may be measured to ensure proper equipment operation. For example, water may have a turbidity of about 1.11 NTU and isopropyl alcohol may have a turbidity of about 0.15 NTU. It is believed that improved emulsification of active ingredients, particularly hydrophobic active ingredients, yields lower NTU values.

Surface Tension Method

Surface tension is measured according to ASTM 1331-14 (Published January 2015) using an EZ-Pi tensiometer (Kibron, Parrish, Fla.), or equivalent. The instrument is calibrated according to the manufacturer instructions using DI water. Measurements are taken and values are reported in mN/m.
