Pump style soap dispensers have been in use for quite some time. Dispensers of this type are used until the soap is completely used up or sufficiently depleted so that it can no longer be pumped to the outlet for use. At such time, these dispensers are discarded and replaced with a new dispenser. In these conventional systems, the entire dispenser is discarded together as a single unit, which results in more waste than is necessary. Alternatively, users may refill their dispensers by manually pouring an additional amount of the soap or other liquid from a large refill container into the dispenser. This process typically results in at least some of the liquid product being spilled onto the countertop or floor, thereby creating an undesirable mess. A final problem with existing dispensers is that a significant amount of the product cannot be evacuated from the container. Thus, there is a need for a convenient and mess-free system that allows for replenishment of the liquid product that can be easily achieved by persons of all ages and dexterity and that enables some components of the system to be used with multiple replenishment cartridges, thereby reducing waste. Furthermore, there is a need for a dispenser of liquid product that enables a greater amount, and preferably all, of the liquid product to be dispensed for use.
The invention is directed to a system for dispensing a fluid, such as a hand soap or the like. The system includes a dispenser and/or a refill cartridge. The dispenser includes a dispenser body having a refill cavity, a dispenser lid configured to be coupled to the dispenser body, and a pump sub-system mounted to the dispenser lid. The pump sub-system includes a first dip tube, a dispensing orifice, and a pump. The refill cartridge includes a cartridge body having a fluid cavity, a store of a fluid in the fluid cavity, and a second dip tube extending into the store of the fluid. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

The dispenser body 110 may be formed from an injection molded plastic and the cartridge body 210 may be formed from a blow molded plastic. More specifically, the cartridge body 210 may be a thin wall blown polyethylene terephthalate (PET). In some embodiments, the dispenser body 110 may have a first rigidity and the cartridge body 210 may have a second rigidity such that the first rigidity is greater than the second rigidity. Thus, the dispenser body 110 may be formed of a harder material than the cartridge body 210. In some embodiments, the vertical force that occurs during pumping and dispensing may be fully or almost fully (i.e., 90% of the force) imparted onto the dispenser body 110 so as not to damage the cartridge body 210 during such pumping and dispensing.
As shown in
Thus, the dispenser body 110 forms an outer container of the system 1000 and the refill cartridge 200 forms an inner container of the system 1000. The refill cartridge 200 can be replaced when the fluid 205 contained therein is depleted or when it is desired to swap the fluid 205 out for a different personal care fluid. For example, if a user no longer enjoys the scent of a particular soap, the user can remove the refill cartridge 200 that is currently located in the dispenser body 100 and replace it with a different refill cartridge having a different personal care fluid therein. The dispenser 100 (including the dispenser body 110, the dispenser lid 140, and the pump sub-system 170) may be reused with multiple refill cartridges 200. The refill cartridge 200 does not have its own pump, but rather only works when coupled to the pump sub-system 170 of the dispenser 100.
Referring to
The dispenser body 110 comprises an outer surface 111 and an inner surface 112 opposite the outer surface 111. The inner surface 112 of the dispenser body 110 defines the refill cavity 113 that is sized and configured for receiving the refill cartridge 200 therein as described in more detail herein below. In the exemplified embodiment, the refill cavity 113 has an open top end 114 located at a top edge 117 of the dispenser body 110 and an open bottom end 115 located at a bottom edge 116 of the dispenser body 110. Of course, the bottom end 115 need not be open in all embodiments. In the exemplified embodiment, the dispenser body 110 has a circular transverse cross-sectional shape such that the top edge 117 of the dispenser body 110 is circular. However, the invention is not to be so limited in all embodiments and the dispenser body 110 may have a square, rectangular, triangular, or other shaped transverse cross-section in other embodiments. In some embodiments, the shape of the dispenser body 110 or the shape of the refill cavity 113 thereof should match or correspond with the shape of the cartridge body 210 so that the cartridge body 210 can be inserted into the refill cavity 113.
The dispenser body 110 extends along a dispenser axis A-A from the top edge 117 to the bottom edge 116. Thus, the dispenser body 110 of the exemplified embodiment is a tube-like container that is open on both opposing ends thereof. The refill cavity 113 may have a constant transverse cross-sectional area along its length and the transverse cross-sectional area may be circular (as shown) or rectangular or square. Of course, in other embodiments only the top end 114 may be open and the bottom end 115 may be closed. However, forming the dispenser body 110 with the open top and bottom ends 114, 115 eases manufacturing of the dispenser body 110 via an injection molding operation/process. Generally, the refill cartridge 200 is inserted into (and removed from) the refill cavity 113 via the open top end 114 of the dispenser body 110. In the exemplified embodiment, the refill cartridge 200 cannot be inserted into the refill cavity 113 via the open bottom end 115 because it does not fit, but the cartridge body 210 and/or the dispenser body 110 could be reconfigured so that the cartridge body 210 fits through the bottom end of the dispenser body 110 in other embodiments.
Referring to
In this embodiment, there is a first coupling element 124 provided on the outer surface 123 of the neck portion 121 of the dispenser body 110. Of course, it may be possible for the first coupling element 124 to be located on the inner surface 122 of the neck portion 121 of the dispenser body 110 or at other locations along the dispenser body 110 in other embodiments. In the exemplified embodiment, the first coupling element 124 comprises a plurality of angled protuberances arranged about the neck portion 121. However, the invention is not to be so limited and the first coupling element 124 could take on other structures. The first coupling element 124 is intended to interact or mate with coupling elements on the dispenser lid 140 so that the dispenser lid 140 can be coupled to the dispenser body 110. In some embodiments, this coupling may be achieved by mating protuberances/recesses as shown, but in other embodiments this coupling may be achieved by an interference fit, a snap fit, hooks, clips, locking mechanisms, or the like. Thus, the exact structure of the first coupling elements 124 and the manner in which the dispenser lid 140 is coupled to the dispenser body 110 is not intended to be limiting of the invention in all embodiments.
Referring to
In the exemplified embodiment, the neck 142 is threaded and terminates in a distal end 144 having an opening 145 to facilitate coupling of the pump sub-system 170 to the dispenser lid 140. The main body 141 has a top portion 146 that slopes downwardly in an angled manner from the neck 142 and a flange 147 that extends from the top portion 146 to a terminal edge 148. In the exemplified embodiment, the flange 147 has a circular or round shape that matches the shape of the top edge 117 of the dispenser body 110, although the invention is not to be so limited in all embodiments.
The flange 147 comprises a plurality of coupling elements 151 that are configured to engage/mate with the coupling elements 124 of the dispenser body 110 to couple the dispenser lid 140 to the dispenser body 110 (see
The dispenser lid 140 is configured to be alterable between: (1) a first state in which the top end 114 of the refill cavity 113 is open so that the refill cartridge 200 can be slid into and out of the refill cavity 113 (see
In some embodiments, the coupling of the dispenser lid 140 to the dispenser body 110 creates an audible “click” as the coupling elements 151 of the dispenser lid 140 become fully engaged with the coupling elements 124 of the dispenser body 110. Specifically, referring to
Typically, containers similar to the cartridge body 210 that house the fluidic material that is to be dispensed are blow molded and have thin walls that can be squeezed. The invention described herein allows this thin-walled cartridge body 210 to be housed within the thicker, more rigid structure of the dispenser body 110 to such an extent that no part of the cartridge body 210 can be seen by a person using the system 1000 to dispense the fluid. This may be done to provide a desired aesthetic, to make the dispensing system appear more robust, or for any number of other consumer-focused reasons. It may also reduce costs because a consumer need only replace the refill cartridge 200, which does not include a pump system at all. The pump sub-system 170, which may be the most expensive component of the system 1000, can be reused with multiple refill cartridges 200 which can reduce costs and waste.
As mentioned briefly above, the pump sub-system 170 comprises the first dip tube 171, the dispensing orifice 172, the dosage housing 185, and the pump 173. The pump sub-assembly 170 also comprises a collar 174 and an actuator 175. The collar 174 has a threaded inner surface that is configured to mate with the threads on the neck 142 of the dispenser lid 140 to couple/mount the pump sub-system 170 to the dispenser lid 140. In that regard, the collar 174 has a greater diameter than the neck 142 to enable the collar 174 to surround the neck 142 during coupling. An outer surface of the collar 174 may be covered with a cap or other coating that matches the cap member described previously to provide for a seamless aesthetic.
In the exemplified embodiment, the first dip tube 171 terminates in a distal end 177 that is angled relative to the axis A-A. In other embodiments, the first dip tube 171 may taper in a direction towards the distal end 177 to form a point at the distal end 177. This enables the first dip tube 171 to be used to puncture a film or other cover that may be place atop the refill cartridge 200, as described in more detail below. The first dip tube 171 may extend further than that which is shown in the exemplified embodiment. Furthermore, distal end 177 of the first dip tube 171 may be flat and horizontally oriented in other embodiments rather than coming to a point.
During assembly, the first dip tube 171 is inserted into and through the opening 145 in the neck 142 of the dispenser lid 140 until the threads of the collar 174 engage the threads of the neck 142. At this time, the collar 174 is rotated relative to the neck 142 so that the threads mate to couple the pump sub-system 170 to the dispenser body 140. The first dip tube 171 extends entirely through the dispenser lid 140 so that it can engage features of the refill cartridge 200 as described more fully below. Once assembled, the personal care fluid can be pumped from the refill cartridge 200 to the orifice 172 in the pump sub-system 170 for dispensing into a user's hand or the like by pressing downwardly on the actuator 175 in the direction of the axis A-A and then releasing the actuator 175. This action, which is the conventional operation for dispensing containers of this type, pumps the personal care fluid to the outlet 172, as described in greater detail below. In other embodiments, the sequence of inserting the first dip tube 171 into the opening of the refill cartridge 200 can happen concurrently with the coupling of the dispenser lid 140 to the dispenser body 110 or even after the dispenser lid 140 is coupled to the dispenser body 110. For example, the pump sub-system 170 may not be mounted to the dispenser lid 140 as the dispenser lid 140 is coupled to the dispenser body 110. The pump sub-system 170 may be mounted to the dispenser lid 140 only after the dispenser lid 140 is coupled to the dispenser body 110 so that the first dip tube 171 penetrates into the refill cartridge 200 only after the dispenser lid 140 and dispenser body 110 are coupled together. Thus, variations in the assembly procedure are possible and can be determined by the consumer.
The first dip tube 171 does not extend to or even near the bottom of the fluid cavity 213 of the refill cartridge 200. Rather, the first dip tube 171 extends to a location that is approximately 25%-40% into the length of the fluid cavity 213. However, the second dip tube 250 of refill cartridge 200 extends to near or at the bottom of the fluid cavity 213. The first and second dip tubes 171, 250 are fluidly coupled together when the dispenser lid 140, with the pump sub-system 170 mounted thereon, is coupled to the dispenser body 110 and the refill cartridge 200 is positioned within the refill cavity 113. As a result, the liquid/fluid in the fluid cavity 213 is able to flow up the second dip tube 250 and then into the first dip tube 171 where it can then be dispensed through the dispensing orifice 172 of the pump sub-system 170.
Referring to
The cartridge body 210 of the refill cartridge 200 has an inner surface 211 and an outer surface 212 opposite the inner surface 211. The inner surface 211 of the cartridge body 210 defines the fluid cavity 213 that contains the store of the fluid 205 (shown in
The cartridge body 210 comprises an upper neck portion 292 and a lower reservoir portion 291. The upper neck portion 292 comprises the top end 215 of the cartridge body and the lower reservoir portion 291 is the portion within which the fluid 205 is stored. The cartridge body 210 also comprises a shoulder 218 that, in the exemplified embodiment, is located along the lower reservoir portion 291 of the cartridge body 210. The lower reservoir portion 291 of the cartridge body 210 comprises a first portion 293 that extends from the bottom end 214 of the cartridge body 210 to the shoulder 218 and a second portion 294 that extends from the shoulder 218 to a top end 295 of the reservoir portion 291.
In the exemplified embodiment, the shoulder 218 is a downward facing surface of the cartridge body 210 that circumscribes or surrounds the cartridge axis C-C. The shoulder 218 extends continuously about the entire circumference of the cartridge body 210. The shoulder 218 projects radially outwards from the outer surface of the first portion 293 of the lower reservoir portion 291 to form a surface that can be used to engage the top edge 117 of the dispenser body 110 to suspend the refill cartridge 200 within the refill cavity 113. In the exemplified embodiment, the shoulder 218 is oriented at an oblique angle relative to the cartridge axis C-C (and relative to the dispenser axis A-A when the cartridge body 210 is supported within the refill cavity 113 of the dispenser body 110). As discussed in greater detail below, the shoulder 218 of the cartridge body 210 rests atop the top edge 117 of the dispenser body 110 when the cartridge body 210 is supported in the refill cavity 113 of the dispenser body 110. In the exemplified embodiment, the shoulder 218 and the top edge 117 are oriented at the same oblique angle to create a clean and flush interface between those two surfaces/edges.
The neck portion 292 of the cartridge body 210 is free of threads or other connection features because the dispenser lid 140 is not coupled to the cartridge body 210, but it is instead coupled to the dispenser body 110 as described above. The neck portion 292 comprises an inner surface 281 that comprises a ledge 282. The ledge 282 is a horizontal surface that projects from the inner surface 281 of the neck portion 292 so that the fluid delivery component 270 can rest atop the ledge 282, as described in more detail below.
The neck portion 292 of the cartridge body 210 comprises a lower portion 283 located between the ledge 282 and the reservoir portion 291 and an upper portion 284 located between the ledge 282 and the upper edge 215 of the cartridge body 210. In the exemplified embodiments, the ledge 282 is located equidistant between the top end of the reservoir portion 291 and the upper edge 215, although the invention is not to be so limited in all embodiments. Furthermore, in the exemplified embodiment the upper portion 284 of the neck portion 292 has a greater transverse cross-sectional area than the lower portion 283 of the neck portion 292. The ledge 282 is a horizontal surface that is recessed below the upper edge 215 of the cartridge body 210. As will be discussed below, the fluid delivery component 270 rests atop the ledge 282 such that the fluid delivery component 270 is located entirely within the fluid cavity 213 of the cartridge body 210.
In some embodiments, the cartridge body 210 may be manufactured by an injection stretch blow molding process. The cartridge body 210 can take on various shapes and sizes. As described more fully herein below, the cartridge body 210 (or more specifically the fluid cavity 213) is either vented or the cartridge body 210 may contain or be formed by a collapsible bag that holds the store of the fluid 205 therein to enable proper dispensing operations until the fluid 205 is substantially depleted. The cartridge body 210 may be transparent in some embodiments, although the invention is not to be so limited and it may be translucent or opaque in other embodiments. In embodiments in which the cartridge body 210 is transparent, the store of the fluid 205 contained in the fluid cavity 213 of the cartridge body 210 may comprise a color that is visible through the cartridge body 210 and through the dispenser body 110 to create a desired aesthetic and impart information regarding the scent or the like of the fluid 205 to a user or potential purchaser. The cartridge body 210 may also be decorated in ways similar to the described herein for the dispenser body 110.
As mentioned above, the fluid delivery component 270 comprises the second dip tube 250 and the basket 254. The fluid delivery component 270 extends from a bottom end 271 to a top end 272 along a fluid delivery axis (which is the same as the dispenser body and cartridge body axes A-A, C-C noted in
The second dip tube 250 comprises an inner surface 247 that defines the passageway (or interior) 252. Furthermore, the second dip tube 250 comprises at least one protuberance 246 extending from the inner surface 247 and into the passageway 252. In the exemplified embodiment, the at least one protuberance 246 is an annular protuberance that circumscribes an axis of the fluid delivery member 270. However, in other embodiments the at least one protuberance 246 could comprise a plurality of spaced apart protuberances. In the exemplified embodiment, the protuberance 246 is a nub-like projection having a rounded outer surface, although again the invention is not to be limited to this structure and appearance in all embodiments. In the exemplified embodiment, the at least one protuberance 246 is intended to couple the first dip tube 171 of the pump sub-system 170 to the second dip tube 150 of the refill cartridge 100, which provides a coupling between the pump sub-system 170 and the refill cartridge 100 as described further below. Of course, in some embodiments the protuberance 246 could be omitted and the diameters of the first and second dip tubes 171, 250 could be modified to ensure that when the first dip tube 171 is located within the passageway 252 of the second dip tube 250, the first and second dip tubes 171, 250 are coupled together with a friction-type fit.
The fluid delivery component 270 also comprises the basket 254 extending upward from the second dip tube 250. The protuberance 246 is located along the second dip tube 250 at a location that is adjacent to the basket 254. As a result, the first dip tube 171 does not need to extend very far into the second dip tube 250 for the frictional coupling to be achieved between the two. In the exemplified embodiment, the basket 254 and the second dip tube 250 are an integral structure referred to herein as the fluid delivery component 270. In other embodiments, the basket 254 could be separate and distinct component from the second dip tube 250.
The basket 254 comprises an inner surface 256 that defines a basket cavity 257. In the exemplified embodiment, the basket 254 is formed integrally with the second dip tube 250 and the basket 254 and the second dip tube 250 extend along the cartridge axis C-C. However, the basket 254 could alternatively be formed integrally with the cartridge body 210 or it could be its own component separate from the second dip tube 250 and from the cartridge body 210. In some embodiments, the basket 254 is configured to align the first dip tube 171 with the second dip tube 250 and guide the first dip tube 171 into the second dip tube 250 as the dispenser lid 140 is being coupled to the dispenser body 110. As seen in
The basket 254 comprises a first portion 241 that is adjacent to the top end 272 of the fluid delivery member 270 and a second portion 242 that extends from the first portion 241 to the second dip tube 250. The first and second portions 241, 242 of the basket 254 are distinguishable from one another based on their diameters or transverse cross-sectional areas. Specifically, the first portion 241 has a greater diameter or transverse cross-sectional area than the second portion 242. This is important in some embodiments, particularly those that use an alternative cartridge cap as described below with reference to
In the exemplified embodiment, the basket 254 comprises one or more vent passageways 243 (visible in
In the exemplified embodiment, the fluid delivery component 270 comprises a flange 273 that extends radially from an outer surface of the fluid delivery component 270 in a direction away from the axes A-A, C-C. In the exemplified embodiment, the flange 273 is located at the top end 272 of the fluid delivery component 272 such that the flange 273 is flush with the top end 272 and/or forms the top end 272 of the fluid delivery component 272.
As mentioned above, the refill cartridge 200 also comprises the cartridge lid 260. In the exemplified embodiment, the cartridge lid 260 comprises a puncturable film 261 that is induction sealed to the top end 215 of the cartridge body 210 and a cap 262 In some embodiments, the puncturable film 261 may be referred to as an induction liner. The puncturable film 261 may be a transparent film of plastic, a foil, a heat-sealable foil laminate, a thermoplastic material, an aluminum foil, or the like. Specifically, any type of film known for use in sealing the top ends of containers (such as commonly used on pill bottles or the like) can be used as the puncturable film 261. The puncturable film 261 should be designed so that an axial force applied onto the puncturable film 261 will puncture the puncturable film 261 and provide access into the fluid cavity 213 of the cartridge body 210.
The cap 262 may be formed from a hard plastic and comprises an inner edge 263 that defines an opening 264. Thus, the cap 262 is not a fully enclosed cap and if the cap alone were coupled to the top end 215 of the cartridge body 210, the cap 262 would not seal the fluid cavity 213. Rather, the cap 262 is only used in conjunction with the puncturable film 261. In some embodiments, the cap 262 may be omitted and the puncturable film 261 by itself may form the entirety of the cartridge lid 260. The cap 262 may be referred to as being donut-shaped or ring-shaped in some embodiments.
As best seen in
It should be appreciated that the refill cartridge 200 is entirely free of a pump. Rather, it is only by fully assembling the system 1000 such that the first dip tube 171 of the pump sub-system 170 of the dispenser 100 engages the second dip tube 250 of the refill cartridge 200 that it becomes possible to dispense the fluid 205 from the refill cartridge 200. Thus, the refill cartridge 200 may be sold by itself as a personal care fluid refill container to replace one that has been depleted without having to also sell a pump along with the refill cartridge 200 because the pump sub-system 170, which is a part of the dispenser 100, can be re-used to dispense the personal care fluid from the refill cartridge 200 and any refill cartridge that it is subsequently mated with.
Referring to
Furthermore, when the refill cartridge 200 is positioned within the refill cavity 113 of the dispenser body 110, the shoulder 218 of the cartridge body 210 contacts and rests atop of the top edge 117 of the dispenser body 110 to support the refill cartridge 200 in the refill cavity 113 of the dispenser body 110. Thus, the shoulder 218 does not enter into the refill cavity 113, but rather rests directly atop the top edge 117 of the dispenser body 110. In the exemplified embodiment, the shoulder 218 and the top edge 117 are oriented at a similar, if not the same, oblique angle relative to the dispenser axis A-A, which creates a flush, smooth interface between the shoulder 218 and the top edge 117. When supported in the refill cavity 113, the outer surface 211 of the cartridge body 210 is spaced apart from the inner surface 112 of the dispenser body 110 along an entire length of the cartridge body 210 from the shoulder 218 to the bottom end of the cartridge body 210. Furthermore, the refill cartridge 200 is supported within the refill cavity 113 in a suspended manner so that a space exists below the lowermost surface/bottom end of the refill cartridge and a surface (i.e., a shelf, a countertop, a medicine cabinet, or the like) upon which a bottom end 116 of the dispenser 200 rests.
The portion of the cartridge body 210 above the shoulder 218 has a cross-sectional profile that does not fit through the open top end 114 of the dispenser body 110. Thus, when the cartridge body 210 is inserted into the refill cavity 113, the shoulder 218 and the second portion 294 of the reservoir portion 291 cannot pass through the open top end 114 of the dispenser body 110.
In the exemplified embodiment, when the refill cartridge 200 is suspended within the refill cavity 113, a portion of the cartridge body 210 is located within the refill cavity 113 and a portion of the cartridge body 210 protrudes from the top edge 117 of the dispenser body 110 and is not located within the refill cavity 113. More specifically, the first portion 293 of the reservoir portion 291 of the cartridge body 210 is located within the refill cavity 113 and the second portion 294 of the reservoir portion 291 and the neck portion 292 protrude from and are not located within the refill cavity 113. In some embodiments between 15% and 35%, and more specifically 20% and 30%, and still more specifically 22% and 28% of the length of the cartridge body 210 protrudes from the refill cavity 113 of the dispenser body 110 when the shoulder 218 of the cartridge body 210 rests atop the top edge 117 of the dispenser body 110.
In the exemplified embodiment, the neck portion 121 of the dispenser body 110 has an outer diameter D1 and the cartridge body 210 has an outer diameter D2 located just above the shoulder 218. The outer diameter D2 of the cartridge body 210 may be the maximum outer diameter of the cartridge body 210. In the exemplified embodiment, the outer diameter D1 of the neck portion 121 is greater than the outer diameter D2 of the cartridge body 210. This ensures that there is a small gap between the cartridge body 210 and the dispenser lid 140 when the dispenser lid 140 is coupled to the dispense body 110. Thus, the cartridge body 210 does not interfere with the coupling of the dispenser lid 140 to the dispenser body 110.
Furthermore, in the fully assembled system 1000, the first dip tube 171 of the pump sub-system 170 extends into the passageway or the interior 252 of the second dip tube 250 that is located within the fluid cavity 213. Specifically, as the dispenser lid 140 is coupled to the dispenser body 110, the first dip tube 171 of the pump sub-system 170 pierces the cartridge lid 160 and enters into the fluid cavity 213. The fluid delivery component 250 is located within the fluid cavity 213 and spans the entire width of the fluid cavity 213, thereby forcing the first dip tube 171 of the pump sub-system 170 to pass into the basket cavity 257 and then into the passageway 252 of the second dip tube 250. When fully assembled as shown in
As noted previously, the refill cartridge 200 is coupled to the pump sub-system 170 of the dispenser 100. As a result, and as described in greater detail below with reference to
In certain embodiments, the first dip tube 171 may include a resilient portion so that as the first dip tube 171 begins to contact the protuberance 246, the first dip tube 171, or a portion thereof, will flex radially inward. Thus, the force of the resilient portion of the first dip tube 171 attempting to flex back outward being applied against the protuberance 246 creates a reasonably strong frictional engagement between the first and second dip tubes 171, 250 to achieve the functionality described herein.
Referring to
Of course, it should be appreciated that in some embodiments the first dip tube 171 may be omitted. For example, in some embodiments the bottom end of the dosage housing 185 may be used to penetrate the cartridge lid 265 rather than the first dip tube 171. In such embodiments, the dosage housing 185 will be fluidly coupled to the fluid delivery member 270 of the refill cartridge 200 to ensure that the fluid 205 can still be pumped from the fluid cavity 213 to the dosage chamber 186, and from there out there the dispensing orifice 172 for use by a consumer.

The actuator 175 is also operably coupled to a spring 189 such that upon release of the actuator 175, the spring 189 will bias the actuator 175 back into its original non-actuated position. During this biasing of the actuator 175, the valve 188 opens and an amount of the fluid 205 flows from the fluid cavity 213 into the dosage chamber 186. The amount of the fluid 205 is then prepared for dispensing via the dispensing orifice 172 the next time that the actuator 175 is actuated. As mentioned previously, the basket 254 comprises vent passageways 243 that permit the flow of air from the atmosphere into the fluid cavity 213 to replace the amount of the fluid 205 that flows from the fluid cavity 213 into the dosage chamber 186. In alternative embodiments, the fluid cavity 213 could be defined by a collapsible bag such that air is not needed to replace the lost volume of the fluid 205, but instead the collapsible bag will simply collapse thereby reducing the volume of the fluid cavity 213 during dispensing.
While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope of the present invention. Thus, the spirit and scope of the invention should be construed broadly as set forth in the appended claims.
