Spray dispensing device with nozzle closure

Abstract
In accordance with embodiments of the present invention, an apparatus includes an actuator with a spray nozzle and an opening adjacent the spray nozzle. The actuator dispenses spray through an orifice in the spray nozzle when the actuator is depressed to operate a pump or an aerosol valve. A wall including the spray opening at least partially surrounds the actuator and the spray nozzle is aligned with the spray opening during dispensing whereby spray exiting the spray nozzle orifice passes through the spray opening. Also included is a nozzle closure, with a first projection and a second projection. The first projection, forming a sealing rim with an inner recess, fits into the opening adjacent the spray nozzle thereby sealing the spray nozzle. The nozzle closure has a hinge allowing pivotal movement of the nozzle closure from a closed position, at which the first projection fits into the opening in the wall adjacent the spray nozzle and the nozzle closure closes the spray opening, to an open position, where the spray opening is open to permit the spray to pass through the spray opening when the actuator is depressed. The second projection fits within the inner recess of the first projection, and, when the nozzle closure is in a closed position, the second projection sealingly engages the orifice of the spray nozzle and displaces any spray deposits that may have accumulated therein. In another embodiment, a third projection may also be provided on the nozzle closure. The third projection may be located on the closure between the hinge and the first projection and may fit in a recess in the actuator, engaging the recess when the nozzle closure is in a closed position and preventing actuation of the actuator when the nozzle closure is closed.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a spray dispensing device with a closure for the spray nozzle. In particular, the present invention relates to a nozzle closure which includes structure to provide a seal for a dispensing actuator to prevent air or contaminants from causing clogging, which may lock the dispensing actuator when not in use and which may provide a measure of child-resistance. The present invention may also include structure to provide evidence of tampering with the nozzle closure.




2. Description of the Prior Art




In U.S. Pat. No. 5,158,211 (the “'211 patent”), issued Oct. 27, 1992, a mechanism is disclosed for sealing the outlet nozzle of a spray actuator when the dispenser is not in use to prevent accidental discharge of liquid. The mechanism for sealing the dispensing orifice prevents drying of the contents of the container in the spray orifice, thereby preventing clogging of the spray orifice. However, the device disclosed in the '


211


patent requires that the actuator be rotated to a non-dispensing position for the sealing device to seal the orifice. Furthermore, this device has a removable tab for the dispensing position. Such a removable tab leaves an opening in the actuator shroud which can be the repository for dirt or dust, which can interfere with operation of the actuator or nozzle.




In the applications listed above, embodiments of nozzle closures which are mounted for pivoting movement from a closed to an open position are used with a spray dispensing device. In the open position, the nozzle closure moves away from the spray nozzle on an actuator and a spray opening in a surrounding wall, allowing fluid to dispensed through the nozzle, as the actuator is depressed. In the closed position, the nozzle closure pivots into a position where a projection enters at least partially into the spray nozzle. The projection acts to seal the spray nozzle against air, thereby preventing drying of any fluid in the nozzle and reducing the chance that the spray nozzle will become clogged. The nozzle closure in these embodiments also serves to provide resistance against depression of the actuator, to prevent accidental discharge from the spray nozzle.




Although, these embodiments have proven effective, in some cases the projection does not provide sufficient resistance against accidental discharge, for example, in the case where the source of material for the spray nozzle is an aerosol valve, or, in the case of undesired actuation by children. Thus, there is a need for a better nozzle closure which more positively prevents accidental discharge.




SUMMARY OF THE INVENTION




In accordance with embodiments of the present invention, an apparatus includes an actuator with a spray nozzle and an opening adjacent the spray nozzle. The actuator dispenses spray through an orifice in the spray nozzle when the actuator is depressed to operate a pump or an aerosol valve. A wall including the spray opening at least partially surrounds the actuator and the spray nozzle is aligned with the spray opening during dispensing whereby spray exiting the spray nozzle orifice passes through the spray opening. Also included is a nozzle closure, with a first projection and a second projection. The first projection, forming a sealing rim with an inner recess, fits into the opening adjacent the spray nozzle thereby sealing the spray nozzle. The nozzle closure has a hinge allowing pivotal movement of the nozzle closure from a closed position, at which the first projection fits into the opening in the wall adjacent the spray nozzle and the nozzle closure closes the spray opening, to an open position, where the spray opening is open to permit the spray to pass through the spray opening when the actuator is depressed. The second projection fits within the inner recess of the first projection, and, when the nozzle closure is in a closed position, the second projection sealingly engages the orifice of the spray nozzle and displaces any spray deposits that may have accumulated therein. In another embodiment, a third projection may also be provided on the nozzle closure. The third projection may be located on the closure between the hinge and the first projection and may fit in a recess in the actuator, engaging the recess when the nozzle closure is in a closed position and preventing actuation of the actuator when the nozzle closure is closed.

DETAILED DESCRIPTION





FIG. 14

show a container


402


with a mounting cap


417


which includes a first embodiment of the nozzle closure of the present invention. Details of the container


402


and mounting cap are described in U.S. Pat. No. 5,875,932 and 5,620,113, the disclosures of which patents are incorporated herein by reference. The mounting cap


417


shown in

FIGS. 1-4

is particularly effective in ensuring a leakproof and easy-to-assemble mounting of pump


12


onto container portion


402


without the need for complicated molding of container portion


402


.




Mounting cap


417


includes an interior piston portion


480


, which slides in and seals against an interior sealing surface of container portion


402


. Actuator


6


includes a downwardly extending projection


7


, In fluid communication with spray nozzle


9


, which sealingly engages an upwardly projecting stem


8


of pump


12


.




Container portion


402


also includes, at its upper end, an angled snap rim extending around the entire circumference of container portion


402


. The snap rim includes a lower snap surface, and mounting cap


417


includes an exterior snap flange


486


which is used to secure and seal mounting cap


417


to container portion


402


. The container portion


402


may include a bottom closure


217


with an inner piston portion


200


and an exterior snap flange


286


.





FIGS. 2-4

show the details of the first embodiment of spray nozzle closure for sealing the nozzle


9


on actuator


6


. An upstanding wall


403


on mounting cap


417


has mounted thereon, by way of a vertical hinge


440


, a sealing finger


404


. Hinge


440


can be of any known type, including a molded pin on upstanding wall


403


fitting within a hole in the cylindrical portion


441


of sealing finger


404


. Through the mounting described above, since it is part of the mounting cap


417


, wall


403


is mounted to container portion


402


. This arrangement allows the sealing finger


404


to be detachably connected to the wall


403


, which remains fixed to container portion


402


. Cylindrical portion


441


of sealing finger


404


fits within a semi-circular recess


442


in actuator


6


. The fit between cylindrical portion


441


and recess


442


ensures that actuator


6


may not be rotated such that spray nozzle


9


is not aligned with spray opening


425


in upstanding wall


403


. Sealing finger


404


also includes a tapered projection


446


. Actuator


6


has a matching recess


448


.




Sealing finger


404


, when it is desired to dispense fluid, in the form of spray, from container portion


402


, is pivoted away from the spray nozzle


9


, to the position shown in

FIGS. 2 and 4

. Thereafter, the actuator is depressed, and spray exits the spray nozzle


9


through spray opening


425


. After dispensing, the sealing finger


404


is pivoted towards spray nozzle


9


, so that a projection in the form of an annular sealing rim


445


engages in an opening adjacent the spray nozzle


9


. This engagement seals the nozzle


9


from the encroachment of air or other debris into spray nozzle


9


, thereby preventing clogging of the nozzle


9


between dispensing strokes. In the closed position, shown in

FIG. 3

, the sealing finger


404


completely covers spray opening


425


. In this closed position the engagement of projection


446


with recess


448


acts to prevent the actuator


6


from being depressed, thereby locking the actuator


6


against accidental discharge. In this embodiment the hinge rotates about an axis parallel to the direction of actuation.




In order to advantageously impart a measure of child resistance to the operation of the nozzle closure, a degree of opening resistance can be provided for the sealing finger


404


. A child may be required to use both hands to overcome the opening resistance and operate the sealing finger


404


from the closed position to the open position, e.g., by grasping container portion


402


in one hand while operating the sealing finger


404


with the other hand. For example, in order to operate the sealing finger


404


from the closed position to the open position, a predetermined amount of force can be required to overcome the friction developed between the contacting edges of the sealing finger


404


and the wall


403


. In this case, a press fit can be created, between the sealing finger


404


and the wall


403


, by slightly oversizing the sealing finger


404


relative to the spray opening


425


. In another example, a predetermined amount of force can be required to overcome the friction developed between the contacting edges of the annular sealing rim


445


and the actuator


6


. In this case, a press fit can be created between the annular sealing rim


445


and the actuator


6


by slightly oversizing the annular sealing rim


445


relative to the opening adjacent the spray nozzle


9


. And, in a further example, a predetermined amount of force can be required to overcome the friction developed between the contacting edges of the projection


446


and actuator


6


. In this case, a press fit can be created between the projection


446


and actuator


6


by slightly oversizing the projection


446


relative to the recess


448


. Thus, a range of opening resistances can easily be created by varying the relative dimensions of the appropriate combinations of components.





FIGS. 5-9

show the features of a second embodiment of a nozzle closure with a spray orifice sealing device of the present invention. Upstanding wall portion


3


of a mounting cap or integral container has mounted thereon, on opposite sides of the spray opening


25


, a bearing in the form of lugs


905


. Lugs


905


have a front opening


906


through which the sealing finger


904


lower end may be inserted. Sealing finger


904


includes a hinge


907


mounted on a front surface


908


of sealing finger


904


. This arrangement allows the sealing finger


904


to be detachably connected to the wall


3


. Hinge


907


includes a flattened surface


909


, and other than flattened surface


909


, is cylindrical in shape. Lugs


905


define an opening which is cylindrical in shape, except for a flattened section


910


. Hinge


907


therefore rotates in the opening in lugs


905


, but snap-locks into the position shown as


904


when the flattened surface


909


interacts with flattened section


910


. In this embodiment the hinge rotates about an axis perpendicular to the direction of actuation. Sealing finger


904


includes a closure projection


911


which is shaped so as to sealingly fit within the opening surrounding the spray orifice on the actuator. Accordingly, in the position shown as


904


in

FIG. 5

, the closure portion


911


projects into, and seals, the opening around the spray orifice, preventing air from entering the spray orifice and drying out the liquid in the dispenser. This sealing prevents any potential clogging of the spray orifice. In the position shown as


904


′ in

FIG. 5

, the sealing finger


904


is snapped into a position away from the spray orifice, where the sealing finger


904


will not interfere with the spray from the spray orifice. At the same time the engagement of a projection


915


with a recess


917


acts to prevent the actuator


6


from being depressed, thereby locking the actuator


6


against accidental discharge.




Sealing finger


904


is designed so that front surface


908


lies flush with the outer surface of upstanding wall


3


. In addition, sealing finger


904


is easily inserted into lugs


905


, thereby allowing easy interchangeability of sealing finger


904


onto upstanding wall


3


, so that sealing fingers


904


having different colors, different closure portion


911


sizes and shapes, etc., may be placed on upstanding wall


3


. Furthermore, sealing finger


904


completely fills the spray opening


25


when closure portion


911


is engaged with the spray orifice opening on the actuator so that dirt, sand, or lint does not dog spray opening


25


. As with the embodiment of

FIGS. 1-4

, the embodiment of

FIGS. 5-9

, as noted above, also locks the actuator


6


against accidental discharge, upon insertion of projection


915


into recess


917


. Of course, a degree of opening resistance can be provided for sealing finger


904


in a manner similar to that discussed above for sealing finger


404


in order to impart a measure of child resistance to the present invention.





FIGS. 10-11

are perspective views of a third embodiment which is a variation of the embodiment of

FIGS. 5-9

. Upstanding wall portion


103


of a mounting cap


117


includes a spray opening


125


. This mounting cap


117


may be mounted on a container as shown in FIG.


1


. Alternatively, mounting cap


117


may be a screw-on cap as shown in FIG.


12


. As illustrated the inside portion of the cap


117


may contain threads


151


for screwing onto a container having a threaded neck.




Sealing finger


104


includes a horizontal hinge


107


disposed at the base of a slots


199


formed in wall portion


103


at opposing sides of opening


125


. A bump


197


, past which hinge


47


must be pressed prevent the hinge from coming out of the slot once it is pushed into place. Hinge


107


therefore allows sealing finger


104


to rotate relative to wall portion


103


from an open position (

FIG. 10

) to a closed position (FIG.


11


). Sealing finger


104


includes a projection in the form of an annular sealing rim


145


which is shaped so as to sealingly fit within the opening


147


surrounding the spray orifice


109


on the actuator


6


. Sealing finger


104


also includes a tapered projection


146


which is shaped so as to tightly fit within an opening


148


on the actuator


6


to positively prevent accidental discharge when the sealing finger


104


is in the closed position.




Accordingly, in the position shown in

FIG. 11

, the annular sealing rim


145


projects into, and seals, the opening around the spray orifice


109


, preventing air from entering the spray orifice


109


and drying out the liquid in the dispenser. This sealing prevents any potential clogging of the spray orifice


109


. At the same time, in the position shown in

FIG. 10

, the sealing finger


104


is moved to a position away from the spray orifice


109


, where the sealing finger


104


will not interfere with the spray from the spray orifice and does not block the spray opening


125


.




Sealing finger


104


is designed so that front surface


108


lies flush with the outer surface of upstanding wall


103


. As a result of the insertion of the hinge of the sealing finger into slots, sealing finger


104


is easily inserted into, and removed from, the mounting cap or cap


117


, thereby allowing easy interchangeability of sealing finger


104


, so that sealing fingers


104


having different colors, different annular sealing rim


145


sizes and shapes, etc., may be placed on the mounting cap


117


. This arrangement allows the sealing finger


104


to be detachably connected to the wall


103


. Furthermore, sealing finger


104


completely fills the spray opening


125


when annular sealing rim


145


is engaged with the spray orifice


109


opening on the actuator


6


so that dirt, sand, or lint does not clog spray opening


125


.




As noted above, the embodiment of

FIGS. 10-12

also includes a feature for positively locking the actuator


6


against accidental discharge. Sealing finger


104


includes a locking projection


146


which fits in a recess


148


of actuator


6


when the sealing finger


104


is in the closed position (FIG.


11


). The locking projection


146


in this position therefore prevents the actuator


6


from being depressed downwardly, thereby preventing accidental discharge from the spray orifice


109


. In the open positions shown in

FIGS. 10

, the locking projection


146


moves away from the actuator


6


, thereby allowing depression of the actuator


6


and spray dispensing through the spray orifice


109


. Of course, a degree of opening resistance can be provided for sealing finger


104


in a manner similar to that discussed above for sealing finger


404


in order to impart a measure of child resistance to the present invention.





FIG. 15A

is a cross-sectional view of a variation of the embodiment of

FIGS. 10-12

. An extension


609


can be mounted on the upwardly projecting stem


608


of pump


12


to sealingly engage the downwardly extending member


607


of actuator


606


and the upwardly projecting stem


608


. The extension


609


can be made of different lengths to adapt the actuator


606


for use with various pre-existing containers, pumps, and pump stems not originally designed for use with the present invention. The mounting cap


617


includes a rim


619


extending around the entire circumference of the upper end of the mounting cap


617


. The wall


603


includes an interior flange


620


and an exterior flange


621


, both the interior flange


620


and the exterior flange


621


extend around the entire circumference of the lower end of the wall


603


. A press fit can be established between rim


619


and interior flange


620


to secure the wall


603


to the mounting cap


617


. The inside portion of mounting cap


617


may include interior threads


618


to secure the mounting cap


617


to the container.




The embodiment of

FIG. 1

is directed to a pump. However, the actuators with spray nozzles described herein may also be used with aerosol valves. A specific example of an embodiment of the present invention used with an aerosol valve is shown in

FIGS. 13 and 14

.





FIGS. 13 and 14

show an aerosol container


502


with a mounting cap


517


which includes an embodiment of the nozzle closure of the present invention of the general nature shown in

FIGS. 10 and 11

. The mounting cap


517


shown in

FIGS. 13 and 14

includes a cylindrical skirt


519


which engages a beaded rim


523


of a mounting cup


521


, at the top of the aerosol container


502


, with a press fit attaching mounting cap


517


, and with it wall


503


, to container


502


.




Container


502


includes, at its upper end, a beaded rim


523


extending around its entire circumference. In conventional fashion, this is part of mounting cup


521


. Mounting cup


521


contains an aerosol valve


525


with an upwardly projecting stem


526


, and has, as its purpose, mounting the aerosol valve


525


and stem


526


to the top of container


502


.




The construction and operation of sealing finger


504


with its sealing rim


545


and its tapered projection


546


is as described in connection with

FIGS. 10 and 11

. Sealing finger


504


is shown in the open position in FIG.


13


and in the closed position in FIG.


14


.




The slots


599


in wall


503


by means of which the hinge of the sealing finger


504


is retained are visible, as is the recess


548


into which projection


546


is inserted when the sealing finger


504


is closed. The manner in which sealing rim


545


fits into the recess


547


surrounding the nozzle is shown in FIG.


14


. In this embodiment, with an aerosol valve, accidental actuation is more of a danger and the positive locking effect of projection


546


fitting into matching recess


548


is even more important. Of course, a degree of opening resistance can be provided for sealing finger


504


in a manner similar to that discussed above for sealing finger


404


in order to impart a measure of child resistance to the present invention.





FIG. 15B

is a cut-away perspective view, partially in cross-section, of a variation of the embodiment of

FIGS. 13-14

. An extension


709


can be mounted on the upwardly projecting stem


708


to sealingly engage the downwardly extending projection


707


of actuator


706


and the upwardly projecting stem


708


. The extension


709


can be made of different lengths to adapt the actuator


706


for use with various pre-existing containers, aerosol valves, and valve stems not originally designed for use with the present invention.





FIG. 16

is a perspective view of a variation of the embodiment of

FIGS. 13-14

, showing a removable tab.

FIG. 16

shows an aerosol container


802


with a mounting cap


817


including upwardly extending wall


803


, actuator


806


, and an embodiment of the nozzle closure of the present invention of the general nature shown in

FIGS. 13-14

. The construction and operation of sealing finger


804


is as described in connection with

FIGS. 13-14

, and is shown in the closed position in FIG.


16


. Removable tab


880


can be seen extending upwardly from mounting cap


817


in a position opposing the pivotal movement of sealing finger


804


from the closed position (e.g.,

FIGS. 16 and 14

) to the open position (e.g., FIG.


13


). Removable tab


880


may include a tab portion


881


which is approximately as thick as wall


803


, and a frangible portion


882


that is thinner. Before operating actuator


806


for the first time, removable tab


880


must be broken away from mounting cap


817


. For example, a user may remove the removable tab


880


by grasping aerosol container


802


in one hand and operating the sealing finger


804


from the closed position to the open position with the other hand, thereby breaking removable tab


880


. Or, the user may simply grasp aerosol container


802


in one hand and remove the removable tab


880


with the other hand. In a more skillful example, a dexterous user may grasp aerosol container


802


with one hand and either operate sealing finger


804


or break away removable tab


880


with the index or middle finger of his grasping hand. Although the removable tab


880


is shown in connection with a variation of the embodiment of

FIGS. 13-14

, it can also be employed with the other embodiments, such as that of

FIGS. 10-12

.





FIG. 17

illustrates a further embodiment of the present invention for use with a pressurized dispenser. In such dispensers, the container


1002


is typically cold filled, after which the mounting cup


1021


is crimped onto the container


1002


. This is not a precise operation and variation can occur from machine to machine, for example. The outcome could be variations in position of the actuator


1006


, with the result that the sealing rim


1045


and tapered projection


1046


on the sealing finger


1004


will not match with the recesses


1047


and


1048


, respectively, in the actuator


1006


.




To avoid this problem, the embodiment of

FIG. 17

includes a spring


1050


. The spring extends between a recess


1052


in the mounting cup


1021


and a shoulder


1054


on the bottom of the actuator


1006


. Spring


1050


biases the actuator


1006


outwardly until a projection


1056


, formed on the actuator


1006


, abuts a shoulder


1058


, formed on the sleeve


1060


, which acts as a stop. This is only given as an example of a stop; other ways of accomplishing this objective will be recognized by those of skill in the art. When an abutting relationship exists between the projection


1056


and the shoulder


1058


, the sealing rim


1045


and tapered projection


1046


are in proper alignment with the recesses


1047


and


1048


, respectively. In biasing the actuator


1006


outwardly, the downwardly extending projection


1007


may slide on the upwardly projecting stem


1026
