1. Field of the Invention
Embodiments of the invention relate to dip tube connectors and dip tube connection systems for connecting pumps with containers or bottles having dip tubes integrated therewith.
2. State of the Art
Conventional pump spray systems, such as trigger sprayers or fine mist sprayers, typically employ dip tubes as a means for transporting fluid or product from an interior of a container or bottle to the pump sprayer. While the use of dip tubes is predominant in the industry, there have been attempts to eliminate the dip tube. For example, U.S. Pat. No. 4,863,071, which is incorporated herein by reference, discloses a container and pump unit where the container is formed with an integral liquid supply tube in lieu of a dip tube. Similarly, United States Patent Application 2010/0096415A1, which is incorporated herein by reference, discloses a fluid dispensing container having a bottle and fluid withdrawing assembly for liquids wherein the bottle includes an integral dip tube and the fluid dispensing mechanism may be aligned to allow a direct connection between the integral dip tube and the fluid dispensing mechanism. In each of these examples, the connection between the blown-in dip tube of the bottle or container and the pump spray systems appear to be simple tubes. For instance, the trigger supply lines (34 and 46) described and illustrated in U.S. Patent App. 2010/0096415A1 appear to be nothing more than a tube which slides into a blown-in dip tube.
While the simple engagement of a trigger supply line with a blown-in dip tube may be useful, there may be other instances where more robust fitments between a blown-in dip tube and pump system are needed. In addition, configurations or adaptations which may allow a container or bottle having a blown-in dip tube to be fitted with a traditional trigger sprayer or pump system may be advantageous. Furthermore, improvements in a fitment between a pump sprayer system and a blown-in dip tube may be advantageous.
According to certain embodiments of the invention, a pump system for pumping a liquid through a container or a bottle having a blown-in dip tube may include an improved blown-in dip tube connector. An improved blown-in dip tube connector may include a flexible blown-in dip tube connector. An improved blown-in dip tube connector may also be configured to snap fit or otherwise attach to a valve body of a pump system, to a valve retainer of a pump system, or to a combination of a valve retainer and valve body. In some embodiments, a connection between the blown-in dip tube connector and a blown-in dip tube of a bottle or container may include one or more features configured to retain the blown-in dip tube connector in a blown-in dip tube or to improve a seal between the blown-in dip tube connector and a blown-in dip tube.
For instance, according to certain embodiments of the invention, a blown-in dip tube connector may include a fluid inlet at one end configured to mate with a blown-in dip tube. The blown-in dip tube connector may include one or more dip tube lips configured to mate with a portion of the blown-in dip tube and to provide an improved seal between the blown-in dip tube and blown-in dip tube connector.
In other embodiments of the invention, a blown-in dip tube connector may include one or more seal rings configured to facilitate a seal between a blown-in dip tube connector and a blown-in dip tube when the blown-in dip tube connector is mated with a blown-in dip tube. The one or more seal rings may sit on a seat formed in the blown-in dip tube and may be further retained in position by lips, detents, or other features configured to facilitate a sealed connection between the blown-in dip tube connector and blown-in dip tube. According to certain embodiments of the invention, a seal ring may be bi-injected with the blown-in dip tube connector or may be formed or attached to the blown-in dip tube connector during an assembly process. In some embodiments of the invention, a seal ring material may include a plastic, elastomer, or flexible material. In some embodiments, for example, a seal ring may be made of a thermoplastic elastomer, a thermoplastic urethane or polyurethane, silicon, rubber, or other material.
In still other embodiments of the invention, a blown-in dip tube connector may include one or more dip tube locks which may mate with a detent, lip, or other feature of a blown-in dip tube. A dip tube lock may include a recess, lip, or combination thereof formed in a portion of the blown-in dip tube connector near a fluid inlet thereof. The recess, lip, or combination may be configured to snap lock with a feature on a blown-in dip tube.
In still other embodiments of the invention, a blown-in dip tube connector having one or more dip tube locks may also be fitted with an o-ring or other feature to secure a fluid inlet of the blown-in dip tube connector with a blown-in dip tube. For instance, an o-ring may be seated about a dip tube lock such that when the fluid inlet end of a blown-in dip tube connector is inserted in a blown-in dip tube of a container or bottle, the o-ring may form a seal with the sides of the blown-in dip tube. The seal formed between an o-ring and the side of the blown-in dip tube may provide an improved seal between the blown-in dip tube connector and the blown-in dip tube.
According to various embodiments of the invention, a blown-in dip tube connector may be made of a plastic material. For example, a blown-in dip tube connector may be molded using a high-density polyethylene or medium-density polyethylene. Other materials may also be used as desired.
In various embodiments of the invention, a blown-in dip tube connector may be attached to, or assembled with, a pump system in any number of ways. In some embodiments, for example, a blown-in dip tube connector may include one or more connector lips which may mate with one or more connectors of a valve body to secure the blown-in dip tube connector to the valve body. In other embodiments of the invention, a blown-in dip tube connector may be mated with a valve retainer, or ball retainer, such that the blown-in dip tube connector and valve retainer form a unitary part that may be assembled with a valve body. In such instances, the valve body may be configured to secure the valve retainer, the blown-in dip tube connector, or both.
According to certain embodiments of the invention, a pump system may include a one piece blown-in dip tube connector connected to a valve body of a trigger sprayer and to a blown-in dip tube of a bottle. The one piece blown-in dip tube connector may provide a fluid path between a blown-in dip tube and a trigger sprayer. A one piece blown-in dip tube connector may retain a valve, such as a ball or other type of valve, in a valve body of a trigger sprayer and may be connected thereto. The one piece blown-in dip tube connector may also include a port which may be connected to a blown-in dip tube of a bottle and may fluidly seal with the blown-in dip tube such as with a seal ring, a dip tube lock, an o-ring, a dip tube lip, flange, or other sealing feature.
According to still other embodiments of the invention, a blown-in dip tube connector may include a flexible tube which may act as a direct connection between a blown-in dip tube in a bottle and a trigger sprayer. In some embodiments of the invention, one end of a flexible tube—such as a flexible dip tube—may be inserted into a trigger sprayer or tube retainer of a trigger sprayer in a conventional manner. The opposite end may be inserted into a blown-in dip tube of a bottle and the trigger sprayer connected to the bottle, such as through a conventional bayonet connection or threaded screw connection. The opposite end may seal against or with the blown-in dip tube such that a fluid path is formed between the blown-in dip tube and the trigger sprayer. The flexible tube may bend, curve, or otherwise be positioned such that the connection between the blown-in dip tube and the trigger sprayer is accomplished regardless of whether or not the blown-in dip tube opening and the fluid supply line to the trigger sprayer are in alignment or are offset.
According to other embodiments of the invention, a funnel may be used with a pump system. A funnel may be positioned in a bottle having a blown-in dip tube such that a path to an opening in the blown-in dip tube is created. Assembly of a trigger sprayer having a flexible dip tube to the bottle may then be accomplished in an in-line position such that the trigger sprayer may be assembled in a straight line with the bottle. During assembly, a flexible dip tube will encounter the funnel and be guided into the opening of the blown-in dip tube where a fluid tight seal may be achieved, connecting the blown-in dip tube to the trigger sprayer through the flexible dip tube. In some embodiments of the invention, a funnel may also include one or more openings or slots in the funnel such that a bottle may be filled or refilled through the funnel.
According to still other embodiments of the invention, a blown-in dip tube connector may include a swivel adapter, or rotatable connector, which creates a fluid path from a blown-in dip tube of a bottle to a trigger sprayer. In some embodiments of the invention, a swivel adapter may include a body or head which may be attached to a valve body, tube retainer, or valve retainer of a trigger sprayer. A port may extend away from the head or body of the swivel adapter and may be configured to mate with and seal in an opening of a blown-in dip tube of a bottle. The swivel adapter may be configured such that the swivel adapter can rotate relative to a trigger sprayer to which it is attached so that rotation of the trigger sprayer—for example to remove it from a bottle—will not rotate the swivel adapter when connected to a blown-in dip tube. The rotational feature of the swivel adapter with respect to the trigger sprayer, allows a trigger sprayer to be connected and disconnected to a bottle having a blown-in dip tube on repeated occasions so that the bottle may be refilled as desired.
While the specification concludes with claims particularly pointing out and distinctly claiming particular embodiments of the present invention, various embodiments of the invention can be more readily understood and appreciated by one of ordinary skill in the art from the following descriptions of various embodiments of the invention when read in conjunction with the accompanying drawings in which:
According to various embodiments of the invention, a blown-in dip tube connector may be fitted to, integrated with, or otherwise assembled with a pump sprayer to facilitate the use of the pump sprayer with a container or bottle having a blown-in dip tube. The integration or fitment of the blown-in dip tube connector with a pump sprayer may allow the pump sprayer to be removed from the container or bottle. The integration or fitment of the blown-in dip tube connector with a pump sprayer may also allow the pump sprayer to be removed from the container or bottle and then refitted to the container or bottle as desired. Thus, various embodiments of the invention may be used with pump systems designed to be used on refillable bottles or containers.
A pump system 100 according to various embodiments of the invention is illustrated in
A cross-sectional view of an assembled pump systems 100 according to various embodiments of the invention is illustrated in
As illustrated in
A valve body 150 for a pump system 100 according to embodiments of the invention may include any conventional valve body. Examples of valve bodies 150 which may be used with various embodiments of the invention are illustrated in
A valve body 150 used with embodiments of the invention may include a vent. According to some embodiments, a vent may include a vent connection 152 as illustrated in
A valve body 150 may also include a fluid passageway 156. According to some embodiments of the invention, fluid passing through a blown-in dip tube connector 160 may pass into the fluid passageway 156 and into the piston chamber 151. In other embodiments of the invention, a fluid passageway 156 may be configured to accept and hold or retain a ball retainer 140 assembled with the valve body 150. In such instances, fluid passing from a container through the blown-in dip tube connector 160 may pass through that portion of the ball retainer 140 assembled in the fluid passageway 156.
In some embodiments of the invention, a valve body 150 may include one or more connectors 159. The one or more connectors 159 may be configured to mate with, snap with, fix, or otherwise retain a blown-in dip tube connector 160 with the valve body 150. In some embodiments, the one or more connectors 159 may fit with corresponding features of a blown-in dip tube connector 160 such that the blown-in dip tube connector 160 is maintained in a fixed position with respect to the valve body 150. In other embodiments of the invention, the one or more connectors 159 may fit with corresponding features of a blown-in dip tube connector 160 such that the blown-in dip tube connector 160 may rotate or swivel relative to the valve body 150. For example, the one or more connectors 159 may include a snap ring configured to retain one or more connector lips 165 or connector tabs 175. In other instances, the one or more connectors 159 may include one or more latches as illustrated in
According to various embodiments of the invention, a valve for the pump system 100 may include a ball valve 130 moveably fixed on an interior of the valve body by a ball retainer 140 as illustrated in
In some embodiments of the invention, the ball retainer 140 may also be configured as a dip tube retainer such that a conventional dip tube may be retained by the ball retainer 140 as well. In such configurations, a blown-in dip tube connector 160 would not be utilized. However, the option to dual purpose a ball retainer 140 as both a retainer for the ball valve 130 and as a dip tube retainer may allow a single part to be made for pump systems 100 being used with both traditional dip tube systems and for systems employing containers or bottles having blown-in dip tubes.
While various embodiments of the invention are illustrated with a ball valve 130, it is understood that other valve systems may be incorporated with various embodiments of the invention. For example, a double valve element as described in U.S. Pat. No. 6,641,003, which patent is incorporated herein by reference in its entirety, may be employed with various embodiments of the invention. In such embodiments, the double valve element may be positioned and retained in the fluid passageway 156. In still other embodiments of the invention, a valve system such as that described and illustrated in U.S. Pat. No. 7,175,056, which patent is incorporated by reference herein in its entirety, may be used with a valve body 150 and the pump system 100 having a blown-in dip tube connector 160 may be configured appropriately to utilize such a valve system. In still other embodiments of the invention, a tube retainer having one or more integral valves as illustrated and described in WO2010/124040A2, which patent application is incorporated by reference herein in its entirety, may be used with various embodiments of the invention.
A pump system 100 according to various embodiments of the invention may also include a shroud 190 attached to the valve body 150 or other portion of the pump system 100 as conventionally known. In addition, the pump system 100 may include a nozzle 192 fitted to the valve body 150 as conventionally known.
According to various embodiments of the invention, a pump system 100 may include a blown-in dip tube connector 160. Various configurations for blown-in dup tube connections are illustrated in the Figures.
A blown-in dip tube connector 160 according to various embodiments of the invention is illustrated in
According to certain embodiments of the invention, a blown-in dip tube connector 160 may include one or more connector lips 165 about a periphery of a connector head 164 as illustrated in
According to some embodiments of the invention, the blown-in dip tube connector 160 may also include one or more seal rings 163 which may mate with, contact, or otherwise facilitate a fluid tight seal between the blown-in dip tube connector 160 and a blown-in dip tube of a bottle or container. As a comparison, prior art having tubes which are inserted or snapped directly into a blown-in dip tube may not make a sufficient seal with the blown-in dip tube. In such instances, the necessary vacuum between a pump system and the blown-in dip tube may be lost, which may result in a loss of prime for the pump system. In other instances, the loss of prime may not be recoverable if a seal between a tube and a blown-in dip tube is lost. Thus, the inclusion of one or more seal rings 163 on a blown-in dip tube connector may improve the seal of the blown-in dip tube connector 160 with a blown-in dip tube. The improved seal between the blown-in dip tube connector 160 and a blown-in dip tube may result in improved functionality and reliability of a pump system 100 utilizing a blown-in dip tube container or bottle. In addition, the inclusion of one or more seal rings 163 with embodiments of the invention allows a more robust and repeatable seal between the blown-in dip tube connector and a blown-in dip tube when pump systems 100 according to embodiments of the invention are used with refillable bottles or containers where the pump system 100 may be attached and detached from a container or bottle having a blown-in dip tube multiple times.
For example, a blown-in dip tube connector 160 mated with a blown-in dip tube 960 of a container or bottle 900 according to certain embodiments of the invention is illustrated in
As illustrated in
According to various embodiments of the invention, the one or more seal rings 163 may be made of any desirable material. For example, a seal ring may be made of a thermoplastic elastomer, a thermoplastic urethane or polyurethane, silicon, rubber, or other material. However, in many instances, selection of a material may be made such that the one or more seal rings 163 are compatible with a fluid flowing through the blown-in dip tube connector 160. In some embodiments, the one or more seal rings 163 may be bi-injected with the blown-in dip tube connector 160. In other embodiments, the one or more seal rings 163 may be sprayed on, glued, press-fit, or otherwise connected to a blown-in dip tube connector 160. In addition, in some embodiments a material compatible with the one or more seal rings 163 may be applied to the blown-in dip tube seat 963 to improve the seal between the one or more seal rings 163 and the blown-in dip tube seat 963.

A blown-in dip tube connector 260 according to certain embodiments of the invention is illustrated in
A port 262 according to various embodiments of the invention may include an inlet 261 at the end opposite the connector head 264 and an outlet 267 in the connector head 264. A fluid flow path may be defined between the inlet 261 and outlet 267. According to some embodiments of the invention, the port 262 may include one or more sealing devices located near the inlet 261. For example, the port 262 may include any of a seal ring 163, a dip tube lock 168, an o-ring 178, a dip tube lip 188, flange or other sealing feature described with respect to other embodiments of the invention. In use, a portion of the port 262 near the inlet 261 may seal against or with a blown-in dip tube 960 of a bottle 900.
A valve retainer 240 portion of a blown-in dip tube connector 260 according to embodiments of the invention may include a fluid inlet 241 and a fluid outlet 247. As illustrated, a fluid inlet 241 may include a path through the valve retainer 240 portion of the blown-in dip tube connector 260. In other embodiments, a path extending through the valve retainer 240 portion may be sealed, leaving only a fluid inlet 241 opening. A fluid outlet 247 according to various embodiments of the invention may include a valve seat.
According to various embodiments of the invention, a blown-in dip tube connector 260 may be assembled with a valve body 250 and other components to form a trigger sprayer or pump system 200 which may be assembled with a bottle 900 having a blown-in dip tube 960. When assembled, a portion of a port 262 of the blown-in dip tube connector 260 may seal or mate with the blown-in dip tube 960, forming a fluid tight seal. When operated, fluid may pass through the blown-in dip tube 960, into the blown-in dip tube connector 260 and into the fluid chamber 290 between the blown-in dip tube connector 260 and valve body 250. Further operation of the trigger sprayer may draw fluid from the fluid chamber 290 past the valve 230 and into the piston chamber 251 of the valve body 250 where conventional means are then used to spray such fluid. Thus, a blown-in dip tube connector 260 according to embodiments of the invention may serve as a fluid conduit or fluid flow path between a blown-in dip tube 960 of a bottle 900 and a trigger sprayer or other dispenser.
According to certain embodiments of the invention, a blown-in dip tube connector according to any of the embodiments of the invention may be made of any desirable material. For example, a blown-in dip tube connector may be made of a plastic material. In some embodiments, a blown-in dip tube connector may be made of a polyethylene material. For example, in some embodiments, a blown-in dip tube connector may be made of High-density polyethylene (HDPE). In other embodiments, a blown-in dip tube connector may be made of Medium-density polyethylene (MDPE). In still other embodiments, a blown-in dip tube connector may be made of a material that allows the blown-in dip tube connector to flex such that if a bayonet-type connection between a pump system 100 and bottle 900 is used, removal of the pump system 100 may be facilitated by the ability of the blown-in dip tube connector to flex during removal of the pump system 100 from the bottle 900. For example, as a bayonet connection is removed from a bottle 900, the valve body 150 is typically twisted off of the bottle 900. As the valve body 150 is twisted, a fluid flow path 162 portion of a blown-in dip tube connector 160 may flex allowing the valve body 150 to twist to release the bayonet connection while maintaining a seal or connection between the blown-in dip tube connector 160 and a blown-in dip tube 960.
While various embodiments of the invention are illustrated with a blown-in dip tube connector 160 mated with a valve body 150, a blown-in dip tube connector 160 may also be fitted with or retained by connection with a ball retainer 140. For example, connectors on a ball retainer 140 may mate with or fit with the connectors on the blown-in dip tube connector 160 such that the blown-in dip tube connector 160 and ball retainer 140 snap together. Assembly of the ball retainer 140 and blown-in dip tube connector 160 with a valve body 150 may be made by snap fitment of the ball retainer 140 with the valve body 150, snap fitment of the blown-in dip tube connector 160 with the valve body 150, both snap fitment of the ball retainer 140 and blown-in dip tube connector 160 with the valve body 150 or through other conventional fitment or retention systems.
A pump system 300 according to still other embodiments of the invention is illustrated in
According to certain embodiments of the invention, the use of a flexible tube 360 to create a fluid flow path between a blown-in dip tube 960 and a trigger sprayer is a solution which can be easily adapted to existing trigger sprayers having fluid flow paths that are not in-line with a blown-in dip tube 960 opening of a bottle. For example, as illustrated in
When assembled, a pump system 300 utilizing a flexible tube 360 according to embodiments of the invention provides a bent or curved fluid path from a blown-in dip tube 960 in a bottle 900 to a trigger sprayer. In some embodiments, the flexible tube 360 may provide a fluid path or supply line directly connecting a blown-in dip tube 960 in a bottle 900 to a trigger sprayer fluid supply line or fluid flow path.
Unlike the trigger supply lines illustrated in United States Patent Application 2010/0096415 which include “direct alignment” with an integral dip tube or blown-in dip tube of a bottle, the flexible tube 360 according to embodiments of the invention creates an indirect supply route from the blown-in dip tube 960 to a trigger actuator. In addition, the use of a flexible tube 360 according to embodiments of the invention allows conventional trigger sprayers having fluid supply tubes which are offset from a front portion of a bottle, or offset from the location that a blown-in dip tube 960 of a bottle 900 would be located, to be fitted with a flexible tube 360 and connected to a bottle 900 having a blown-in dip tube 960 as illustrated in
The use of a flexible tube 360 according to embodiments of the invention may also be advantageous in that shortened dip tubes may be used as a flexible tube 360. Alternatively, a trigger sprayer or pump system fitted with a conventionally sized dip tube may have that dip tube cut such that the end of the shortened dip tube may be inserted into a blown-in dip tube 960 of a bottle 900 on the filling line. This may allow conventional trigger sprayers fitted with dip tubes to be used with bottles 900 having blown-in dip tubes 960.
According to embodiments of the invention, a flexible tube 360 may be assembled to a bottle 900 on a filling line. In some embodiments of the invention, a bottle 900 having a blown-in dip tube 960 may be filled, or partially filled, with a fluid product as conventionally known. A pump system 300 fitted with a flexible tube 360 may be aligned such that the flexible tube 360 may mate with an opening in the blown-in dip tube 960 as the pump system 300 is assembled to the bottle 900 on the filling line. After reaching sufficient insertion depth, the pump system 300 may be moved and aligned with the bottle 900 opening such that the pump system 300 may be attached to the bottle 900, for example, using a conventional bayonet fitment system or twist on closure system. The resulting configuration is illustrated in
According to some embodiments of the invention, the ball valve 130 and ball retainer 140 may be substituted with a tube retainer and ball valve 130 or other conventional valve system. For example,
A flexible tube 360 according to embodiments of the invention may be made of a flexible material. For example, in some embodiments of the invention, a flexible tube 360 may be a flexible plastic material. In some particular embodiments, a low-density polyethylene (LDPE) material may be used to make a flexible tube 360 according to embodiments of the invention.
According to other various embodiments of the invention, a pump system 400 may include a funnel 470 as illustrated in
According to various embodiments of the invention, a funnel 470 may include one or more openings 472 in the side walls of the funnel 470. The one or more openings 472 in the side walls of the funnel 470 may allow a fluid to pass through the funnel 470 and fill the bottle 900. For example, a bottle 900 fitted with a funnel 470 having one or more openings 472 may be filled by directing fluid into the funnel 470. As fluid enters the funnel 470 it may pass through the one or more openings 472 and into an interior portion of the bottle 900. In some embodiments of the invention, a funnel 470 may be inserted in a bottle 900 prior to filling of the bottle 900 on a fill line and the bottle 900 filled with the funnel 470 in place. According to other embodiments of the invention, a funnel 470 may be added to a bottle 900 following a filling process; thus, a bottle 900 could be filled and a funnel 470 then inserted into the bottle 900 before a pump system 400 or trigger sprayer having a flexible tube 360 is attached to the bottle 900.
According to embodiments of the invention, a funnel 470 may help guide a flexible tube 360 into the opening of a blown-in dip tube 960. As only a portion of the funnel 470 in needed to guide a flexible tube 360, the one or more openings 472 in a funnel 470 may be quite large to allow for filling of a bottle 900 through a funnel 470 or with the funnel 470 fitted in the bottle 900.
A funnel 470 according to certain embodiments of the invention may be secured to the bottle 900 at an opening of the bottle 900, at an opening of the blown-in dip tube 960 or in any other desirable manner.
An embodiment of a pump system 400 including a funnel 470 is illustrated in
According to other embodiments of the invention, a pump system 500 may include a swivel adapter 560, or rotatable connector, which may provide a fluid path between a blown-in dip tube 960 and a trigger sprayer. For example, a swivel adapter 560 according to certain embodiments of the invention is illustrated in
According to some embodiments of the invention, a swivel adapter 560 or rotatable connector may be configured to rotate such that a trigger sprayer utilizing the swivel adapter 560 may be assembled to a bottle 900 having a blown-in dip tube 960 and then disassembled by twisting the trigger sprayer off of a bayonet connection with the bottle 900. A port 562 on the swivel adapter 560 may mate with and seal to an opening of a blown-in dip tube 960. When the trigger sprayer to which the swivel adapter 560 is attached is rotated, the swivel adapter may remain in one location with the port 562 sealed to the blown-in dip tube 960 opening while the rest of the trigger sprayer moves. This feature may allow the swivel adapter to maintain alignment with the blown-in dip tube 960 as the pump system 500 is removed from a bottle 900. The trigger sprayer and swivel adapter 560 may then be disconnected from the bottle 900 and the seal between the port 562 and blown-in dip tube 960 broken.
A swivel adapter 560 according to various embodiments of the invention is illustrated in
A more detailed view of a swivel adapter 560 or rotatable connector according to various embodiments of the invention is illustrated in
According to embodiments of the invention, a pump system 500 having a swivel adapter 560 may be assembled and disassembled with a bottle 900 having a blown-in dip tube 960. For example, a pump system 500 having a bayonet connection system may be assembled to a bottle 900 having a corresponding connection system as illustrated in
To disengage the pump system 500 from the bottle 900 when a removable bayonet connection exists between the bottle 900 and valve body 150, the trigger sprayer portion of the pump system 500 may be rotated from the position illustrated in 39A to the position illustrated in
To reattach a disengaged pump system 500 having a swivel adapter 560 according to various embodiments of the invention, the pump system 500 may be aligned with the bottle 900 such that the port 562 of the swivel adapter is aligned with an opening in the blown-in dip tube 960. The pump system 500 may then be lowered onto the bottle 900 as illustrated in 41 and twisted back into the attached position illustrated in
According to other embodiments of the invention, a swivel adapter 560 may also be used with a pump system 500 having a non-removable bayonet system for attaching a valve body 150 to a bottle 900. In such embodiments, the non-removable bayonet system may preclude or prevent disengagement of the trigger sprayer portion of the pump system 500 and bottle 900.
According to various embodiments of the invention, a pump system 500 having a swivel adapter 560 may be assembled as illustrated in

According to certain embodiments, a swivel adapter 560 may also include one or more snap beads 567 or other attachment features to connect the swivel adapter 560 to a valve body 150. The one or more snap beads 567 may be configured to mate with or connect a swivel adapter 560 to a valve body 150. For example, one or more snap beads 567 of a swivel adapter 560 may snap into or about one or more connectors 159 on a valve body 150 to retain the swivel adapter 560 to the valve body 150. In various embodiments of the invention, the one or more snap beads 567 may allow the swivel adapter 560 to rotate relative to the valve body 150. In other embodiments, if the rotation or swivel of a swivel adapter 560 is not desired, the one or more snap beads 567 or other attachment features may create a fixed attachment between the swivel adapter 567 and the valve body 150.
According to various embodiments of the invention, the mating of a swivel adapter 560 with a ball retainer 140 may form a fluid chamber on an interior of the two components. When assembled with a valve body 150 and mated with a blown-in dip tube 960, fluid may pass from a blown-in dip tube 960 into the swivel adapter 560 and ball retainer 140 and into a piston chamber 151 of the valve body 150 to be sprayed as conventionally known. Thus, a swivel adapter 560 may provide a fluid connection between a blown-in dip tube 960 and a trigger sprayer.
A swivel adapter 560 according to embodiments of the invention may be made of a plastic or resin material. For example, a swivel adapter 560 may be made of a polyethylene material, high-density polyethylene (HDPE), low-density polyethylene (LDPE), medium density polyethylene (MIDPE), other such material.
