Definitions
- Sunscreen lotion dispensers are well known in the prior art.
- sunscreen lotion is provided in a squeezable tube or container having a simple construction of a deformable reservoir and a discharge opening.
- portions of the tube or the container are squeezed to deform against contents of the reservoir, resulting in lotion being displaced therefrom.
- the resulting rate or amount of dispensed product may not be well controlled with prior art designs.
- maximum depletion of the reservoir may be difficult because of inability to fully urge contained contents out of the reservoir. Users also may inefficiently focus pressure on a portion of the tube or container without maximally exhausting the reservoir.
- Sunscreen lotion is typically applied to the skin by the hands and digits. After the sunscreen lotion is applied, an unwanted residue of sunscreen lotion typically remains on the hands and digits.
- a dispenser for dispensing flowable material, such as sunscreen lotion, including a resiliently deformable body encompassing a closed volume to accommodate flowable material wherein deformation of the body from a natural state causes a reduction of volume of the closed volume.
- a discharge element is also provided having at least one discharge opening defined therein, and at least one valve for regulating the flow of the flowable material.
- a vent is formed to communicate atmosphere outside of the body with the closed volume. The vent allows for introduction of air into the closed volume to facilitate restoration of the body to the natural state after being deformed.
- the body is configured so that a threshold amount of deformation of the body causes sufficient reduction in volume of the closed volume so that flowable material is urged from the closed volume through the discharge opening via the at least one valve.
- the closed volume of the body may serve as a reservoir to hold the flowable material.
- the flowable material in the reservoir is urged from the closed volume through the discharge opening via the at least one valve.
- a flexible pouch formed to accommodate the flowable material, is disposed in the closed volume.
- the body is configured so that a threshold amount of deformation of the body causes sufficient reduction in volume of the closed volume to increase pressure of the closed volume acting on the flexible pouch sufficiently so that flowable material accommodated in the flexible pouch is urged therefrom through the discharge opening via the at least one valve.
- the dispenser of the subject invention allows for generated pressure to be applied to the flexible pouch to cause dispensing therefrom.
- a dispenser for dispensing flowable material, including: a body; a reservoir to accommodate flowable material; a spatula-shaped applicator having opposing faces joined by, and terminating at, a free edge; and, at least one discharge opening defined in one of the faces in proximity to the free edge, the at least one discharge opening being in communication with the reservoir.
- flowable material refers to any generally incompressible material which may be caused to flow under pressure, such as a lotion, ointment, cream, suspended product or slurry.
- FIGS. 1-2 are perspective views of a dispenser formed in accordance with the subject invention.
- FIG. 3 are exploded views of a dispenser formed in accordance with the subject invention.

- FIG. 24 shows an overcap useable with the subject invention.
- a dispenser 10 is shown useable for dispensing flowable material.
- the dispenser 10 may be used for various flowable materials, but is particularly well-suited for use with sunscreen lotion.
- the dispenser 10 generally includes a resiliently deformable body 12 encompassing a closed volume 14 , an optional flexible pouch 16 in the closed volume 14 ; a discharge element 18 having at least one discharge opening 20 defined therein; at least one valve 22 regulating flow to the discharge opening 20 from the closed volume 20 or the flexible pouch 16 as appropriate; and, a vent 24 formed to communicate atmosphere outside of the body 12 with the closed volume 14 .
- the body 12 may be of various configurations including being a unitary construction or a compilation of elements joined together.
- the body 12 may include a cup-shaped piece having a base 26 and a side wall 28 extending upwardly therefrom. Portions of the body 12 , such as portions of the side wall 28 , are formed to be resiliently deformable from an at-rest natural state.
- the at-rest natural state is an unstressed condition.
- the body 12 may be formed to be resiliently deformable by being formed with a constituent material having sufficient inherent memory to return to a natural state upon being released from a deformed state.
- the body 12 may be formed from one or more thermoplastic materials, elastomeric materials, or combinations thereof, to allow for such resilient deformation.
- the volume of the closed volume 14 is caused to be decreased. This, in turn, causes the pressure within the closed volume 14 to increase (as represented by the small arrows within the closed volume 14 ).
- Deformation of the body 12 may be caused by various techniques, including manual application pressure of the body 12 . Release of such pressure allows for the body 12 to return generally to its natural state.
- the closed volume 14 must be sufficiently closed so as to allow for pressure increase therein with a reduction in volume. With the closed volume 14 being closed, restoration of the body 12 to the natural state may not be properly achieved without venting of the closed volume 14 .
- the vent 24 allows for introduction of air into the closed volume 14 to facilitate restoration of the body 12 to the natural state after being deformed.
- the vent 24 may be a one-way vent, configured to permit flow of air into the closed volume 14 and to restrict reverse flow therefrom. Any known configuration may be utilized for the vent 24 including a one-way vent, for example, a duckbill-type valve.
- the vent 24 may in the alternative be open (i.e., not one-way), e.g., defined by one or more interfaces between components of the dispenser 10 through which air may pass into the closed volume 14 .
- a portion of the body 12 may be formed as a removable cap 30 , as shown in the Figures. This allows for a more efficient placement of the flowable material into the closed volume 14 , directly or with the flexible pouch 16 .
- the cap 30 is secured to other portions of the body 12 , such as the side wall 28 , using any known technique, including, but not limited to, mechanical interactions (e.g., interlocking features such as snap engagement detents and grooves, threads, cooperating bayonet locking elements), adhesion, fusion, and so forth.
- the vent 24 may be located on the cap 30 ( FIG. 4A ) and/or defined between the cap 30 and other portions of the body 12 . Alternatively, or additionally, the vent 24 may be located on a different part of the body 12 , such as the base 26 ( FIG. 4B ).
- the flexible pouch 16 may be provided to accommodate a sufficient quantity of the flowable material and may be formed of any flexible film or sheet material which is sufficiently flexible to be responsive to pressure applied thereto as described below.
- the flexible pouch 16 may be formed of a thermoplastic material, e.g., by blow molding.
- the flexible pouch 16 will not be properly vented; this will allow the flexible pouch 16 to contract in response to flowable material being discharged therefrom.
- the closed volume 14 of the body 12 may act as a reservoir for the flowable material.
- the flexible pouch 16 is not required. Deformation of the body 12 may be used to urge the flowable material from the closed volume 14 .
- the flexible pouch 16 includes an opening 32 secured to a portion of the body 12 , such as the cap 30 , through which flowable material may be urged.
- a discharge passage 34 is positioned in the dispenser 10 to receive flowable material discharged from the opening 32 or the closed volume 14 .
- the flexible pouch 16 may be placed into the closed volume 14 during the step of securing the cap 30 to other portions of the body 12 .
- the flowable material may be disposed into the closed volume 14 with the cap 30 thereafter being secured to other portions of the body 12 .
- the discharge passage 34 is defined to pass through a portion of the body 12 , such as the cap 30 .
- the discharge passage 34 may be defined by one or more secondary members, such as a portion of the body 12 (e.g., the cap 30 ), a portion of the discharge element 18 and/or an extension 35 .
- the extension 35 may extend between portions of the body 12 and the discharge element 18 .
- the valve 22 is situated to regulate flow of flowable material from the pouch 16 or the closed volume 14 .
- the valve 22 may be a one-way valve which permits flow from the pouch 16 or the closed volume 14 but restricts flow in a reverse direction.
- the valve 22 may be an adjustable valve which can be selectively adjustable between open and closed states to selectively communicate the opening 32 or the closed volume 14 with the discharge opening 20 .
- the valve 22 may be kept in the closed state when not in use to limit ingress of air and other possible contaminants into the flowable material.
- the valve 22 may be a ball type valve which is rotatable between open and closed states.
- the valve 22 may be a plunger type valve with a rotatable plunger 22 a that is selectively seated in a valve seat 22 b to seal the opening 32 or the closed volume 14 from the discharge opening 20 .
- the plunger 22 a may be formed on the cap 30 with one or more discharge apertures 22 c being formed through the plunger 22 a to permit flow therethrough of the flowable material.
- the valve seat 22 b may be formed on the discharge element 18 . With the plunger 22 a seated in the valve seat 22 b ( FIG. 21 ), the discharge opening 20 is sealed from, and out of communication with, the opening 32 or the closed volume 14 .
- the plunger 22 a may be separated from the valve seat 22 b so as to permit flow of the flowable material to the discharge opening 20 .
- the positioning of the plunger 22 a and the valve seat 22 b on the cap 30 and the discharge element 18 may be reversed.
- more than one valve may be used, e.g., two valves arranged in series; the valves may be of different types (e.g., one-way valve and adjustable valve) or of the same type.
- the valve(s) 22 is/are located on a portion of the body 12 , such as the cap 30 .
- the discharge element 18 is situated to have the discharge opening 20 in communication with the discharge passage 34 and may be formed of various configurations.
- the discharge element 18 may include an applicator 37 .
- the applicator 37 may be spatula-shaped with opposing faces 36 joined by, and terminating at, free edge 38 and with the discharge opening 20 being located in proximity to the free edge 38 .
- the free edge 38 may be utilized to spread sunscreen lotion on the skin of a user.
- the applicator 37 is formed of a compliant material, such as silicon and/or thermoplastic elastomer (TPE), to provide comfort to a user for such application.

Abstract
Description
- Sunscreen lotion dispensers are well known in the prior art. Typically, sunscreen lotion is provided in a squeezable tube or container having a simple construction of a deformable reservoir and a discharge opening. To dispense sunscreen lotion, portions of the tube or the container are squeezed to deform against contents of the reservoir, resulting in lotion being displaced therefrom. There are several drawbacks of this design. The resulting rate or amount of dispensed product may not be well controlled with prior art designs. In addition, maximum depletion of the reservoir may be difficult because of inability to fully urge contained contents out of the reservoir. Users also may inefficiently focus pressure on a portion of the tube or container without maximally exhausting the reservoir. Sunscreen lotion is typically applied to the skin by the hands and digits. After the sunscreen lotion is applied, an unwanted residue of sunscreen lotion typically remains on the hands and digits.
- In one aspect, a dispenser is provided herein for dispensing flowable material, such as sunscreen lotion, including a resiliently deformable body encompassing a closed volume to accommodate flowable material wherein deformation of the body from a natural state causes a reduction of volume of the closed volume. A discharge element is also provided having at least one discharge opening defined therein, and at least one valve for regulating the flow of the flowable material. A vent is formed to communicate atmosphere outside of the body with the closed volume. The vent allows for introduction of air into the closed volume to facilitate restoration of the body to the natural state after being deformed. The body is configured so that a threshold amount of deformation of the body causes sufficient reduction in volume of the closed volume so that flowable material is urged from the closed volume through the discharge opening via the at least one valve.
- The closed volume of the body may serve as a reservoir to hold the flowable material. When the body is deformed, the flowable material in the reservoir is urged from the closed volume through the discharge opening via the at least one valve. Alternatively, a flexible pouch, formed to accommodate the flowable material, is disposed in the closed volume. The body is configured so that a threshold amount of deformation of the body causes sufficient reduction in volume of the closed volume to increase pressure of the closed volume acting on the flexible pouch sufficiently so that flowable material accommodated in the flexible pouch is urged therefrom through the discharge opening via the at least one valve. Advantageously, the dispenser of the subject invention allows for generated pressure to be applied to the flexible pouch to cause dispensing therefrom. This avoids deformation of a tube or bottle directly against a flowable material, such as with the prior art. The generation of pressure within the closed volume allows for a generally isobaric environment to be created which acts evenly about the flexible pouch, rather than certain portions thereof. This allows for a more even application of pressure acting against, and a more complete depletion of the flexible pouch.
- In a further aspect, a dispenser is provided herein for dispensing flowable material, including: a body; a reservoir to accommodate flowable material; a spatula-shaped applicator having opposing faces joined by, and terminating at, a free edge; and, at least one discharge opening defined in one of the faces in proximity to the free edge, the at least one discharge opening being in communication with the reservoir.
- As used herein, the term “flowable material” refers to any generally incompressible material which may be caused to flow under pressure, such as a lotion, ointment, cream, suspended product or slurry.
- These and other features of the invention will be better understood through a study of the following detailed description and accompanying drawings.

FIG. 24 shows an overcap useable with the subject invention. - With reference to the Figures, a
dispenser 10 is shown useable for dispensing flowable material. As will be appreciated by those skilled in the art, thedispenser 10 may be used for various flowable materials, but is particularly well-suited for use with sunscreen lotion. - The
dispenser 10 generally includes a resilientlydeformable body 12 encompassing a closedvolume 14, an optionalflexible pouch 16 in the closedvolume 14; adischarge element 18 having at least one discharge opening 20 defined therein; at least onevalve 22 regulating flow to the discharge opening 20 from the closedvolume 20 or theflexible pouch 16 as appropriate; and, avent 24 formed to communicate atmosphere outside of thebody 12 with the closedvolume 14. - The
body 12 may be of various configurations including being a unitary construction or a compilation of elements joined together. By way of non-limiting example, as shown in the Figures, thebody 12 may include a cup-shaped piece having abase 26 and aside wall 28 extending upwardly therefrom. Portions of thebody 12, such as portions of theside wall 28, are formed to be resiliently deformable from an at-rest natural state. The at-rest natural state is an unstressed condition. Thebody 12 may be formed to be resiliently deformable by being formed with a constituent material having sufficient inherent memory to return to a natural state upon being released from a deformed state. For example, thebody 12 may be formed from one or more thermoplastic materials, elastomeric materials, or combinations thereof, to allow for such resilient deformation. - As shown in
FIG. 12 , with deformation of thebody 12, the volume of the closedvolume 14 is caused to be decreased. This, in turn, causes the pressure within the closedvolume 14 to increase (as represented by the small arrows within the closed volume 14). Deformation of thebody 12 may be caused by various techniques, including manual application pressure of thebody 12. Release of such pressure allows for thebody 12 to return generally to its natural state. - The closed
volume 14 must be sufficiently closed so as to allow for pressure increase therein with a reduction in volume. With the closedvolume 14 being closed, restoration of thebody 12 to the natural state may not be properly achieved without venting of the closedvolume 14. Thevent 24 allows for introduction of air into the closedvolume 14 to facilitate restoration of thebody 12 to the natural state after being deformed. Thevent 24 may be a one-way vent, configured to permit flow of air into the closedvolume 14 and to restrict reverse flow therefrom. Any known configuration may be utilized for thevent 24 including a one-way vent, for example, a duckbill-type valve. Thevent 24 may in the alternative be open (i.e., not one-way), e.g., defined by one or more interfaces between components of thedispenser 10 through which air may pass into the closedvolume 14. - To ease manufacturing and assembly, a portion of the
body 12 may be formed as aremovable cap 30, as shown in the Figures. This allows for a more efficient placement of the flowable material into the closedvolume 14, directly or with theflexible pouch 16. Thecap 30 is secured to other portions of thebody 12, such as theside wall 28, using any known technique, including, but not limited to, mechanical interactions (e.g., interlocking features such as snap engagement detents and grooves, threads, cooperating bayonet locking elements), adhesion, fusion, and so forth. Thevent 24 may be located on the cap 30 (FIG. 4A ) and/or defined between thecap 30 and other portions of thebody 12. Alternatively, or additionally, thevent 24 may be located on a different part of thebody 12, such as the base 26 (FIG. 4B ). - In one embodiment, the
flexible pouch 16 may be provided to accommodate a sufficient quantity of the flowable material and may be formed of any flexible film or sheet material which is sufficiently flexible to be responsive to pressure applied thereto as described below. For example, theflexible pouch 16 may be formed of a thermoplastic material, e.g., by blow molding. In a preferred embodiment, theflexible pouch 16 will not be properly vented; this will allow theflexible pouch 16 to contract in response to flowable material being discharged therefrom. - Alternatively, the
closed volume 14 of thebody 12 may act as a reservoir for the flowable material. With this arrangement, theflexible pouch 16 is not required. Deformation of thebody 12 may be used to urge the flowable material from theclosed volume 14. - The
flexible pouch 16 includes anopening 32 secured to a portion of thebody 12, such as thecap 30, through which flowable material may be urged. Adischarge passage 34 is positioned in thedispenser 10 to receive flowable material discharged from theopening 32 or theclosed volume 14. By utilizing thecap 30, theflexible pouch 16 may be placed into theclosed volume 14 during the step of securing thecap 30 to other portions of thebody 12. Alternatively, the flowable material may be disposed into theclosed volume 14 with thecap 30 thereafter being secured to other portions of thebody 12. - The
discharge passage 34 is defined to pass through a portion of thebody 12, such as thecap 30. Thedischarge passage 34 may be defined by one or more secondary members, such as a portion of the body 12 (e.g., the cap 30), a portion of thedischarge element 18 and/or anextension 35. Theextension 35 may extend between portions of thebody 12 and thedischarge element 18. - The
valve 22 is situated to regulate flow of flowable material from thepouch 16 or theclosed volume 14. In one configuration, thevalve 22 may be a one-way valve which permits flow from thepouch 16 or theclosed volume 14 but restricts flow in a reverse direction. Alternatively, thevalve 22 may be an adjustable valve which can be selectively adjustable between open and closed states to selectively communicate theopening 32 or theclosed volume 14 with thedischarge opening 20. As an adjustable valve, thevalve 22 may be kept in the closed state when not in use to limit ingress of air and other possible contaminants into the flowable material. For example, thevalve 22 may be a ball type valve which is rotatable between open and closed states. Thevalve 22 may be a plunger type valve with arotatable plunger 22 a that is selectively seated in avalve seat 22 b to seal theopening 32 or theclosed volume 14 from thedischarge opening 20. As shown inFIGS. 14-16 , theplunger 22 a may be formed on thecap 30 with one ormore discharge apertures 22 c being formed through theplunger 22 a to permit flow therethrough of the flowable material. As shown inFIGS. 17-19 , thevalve seat 22 b may be formed on thedischarge element 18. With theplunger 22 a seated in thevalve seat 22 b (FIG. 21 ), thedischarge opening 20 is sealed from, and out of communication with, theopening 32 or theclosed volume 14. Through relative movement between thedischarge element 18 and the cap 30 (e.g., relative rotation), theplunger 22 a may be separated from thevalve seat 22 b so as to permit flow of the flowable material to thedischarge opening 20. As will be appreciated by those skilled in the art, the positioning of theplunger 22 a and thevalve seat 22 b on thecap 30 and thedischarge element 18 may be reversed. In addition, more than one valve may be used, e.g., two valves arranged in series; the valves may be of different types (e.g., one-way valve and adjustable valve) or of the same type. Preferably, the valve(s) 22 is/are located on a portion of thebody 12, such as thecap 30. - The
discharge element 18 is situated to have thedischarge opening 20 in communication with thedischarge passage 34 and may be formed of various configurations. By way of non-limiting example, and as shown in the Figures, thedischarge element 18 may include anapplicator 37. Theapplicator 37 may be spatula-shaped with opposingfaces 36 joined by, and terminating at,free edge 38 and with thedischarge opening 20 being located in proximity to thefree edge 38. For example, thefree edge 38 may be utilized to spread sunscreen lotion on the skin of a user. Preferably, theapplicator 37 is formed of a compliant material, such as silicon and/or thermoplastic elastomer (TPE), to provide comfort to a user for such application. In addition, or alternatively, theapplicator 37 may be formed as a cantilevered rib of material (FIG. 5 ) which inherently has compliance. A plurality ofdischarge openings 20 may be likewise utilized, for example arranged in a particular pattern for even distribution of flowable material. - As shown in
FIGS. 5 and 17-19 , thedischarge element 18 may defineside surfaces base 37 a of theapplicator 37. Apocket 18 c, located on the same side as at least one of the discharge opening(s) 20, may be defined where the flowable material may collect during application. Thus, the flowable material may be caused to be discharged from the discharge opening(s) 20 with the material collecting in thepocket 18 c as being applied to a user's skin. Thepocket 18 c may be defined by an angular change in one or more surfaces (e.g., base 37 a being flared) and/or an interface between two or more non-coplanar surfaces (e.g., an interface between theside surface 18 a and the applicator 37). - The
discharge element 18 may be secured to thevalve 22 to cause selective adjustment thereof where thevalve 22 is an adjustable valve. For example, rotation of thedischarge element 18 may be utilized to selectively adjust thevalve 22 between open and closed states. Cooperatingthreads cap 30 and thedischarge element 18, respectively, may be provided to allow for selective rotation therebetween. - With the
dispenser 10 being assembled, apouch 16 may be loaded with flowable material and located inside theclosed volume 14 or the flowable material will be disposed directly into theclosed volume 14 without thepouch 16. For use, thedispenser 10 is initially prepared as needed. For example, thevalve 22 may be adjusted from a closed state to an open state (e.g., by rotating the discharge element 18), as shown inFIGS. 7-10 . It is noted that thedispenser 10 may be considered to be in an “off” state with thevalve 22 closed, such as the state shown inFIGS. 1 and 2 . Thedispenser 10 may be adjusted to an “on” state, such as by rotating the discharge 180 degrees relative to thebody 12. Releasable retaining arrangements may be provided to releasably retain thedischarge element 18 in the “off” and/or “on” states, such as releasable detents. For example, as shown inFIGS. 22-23 , at least onereleasable detent 100 may be provided on thecap 30 formed to nest in a cooperatingrecess 102 formed on a portion of thedischarge element 18. The point of engagement between thedetent 100 and therecess 102 may be used to define the “on” or “off” state of thedispenser 10. As shown inFIGS. 22-23 , more than onedetent 100 may be provided, with each detent, respectively, defining the “on” and the “off” states. Thus,detent 100 a may define the “off” state, while rotation of therecess 102 into engagement withdetent 100 b causes thedispenser 10 to be put into the “on” state. Asecondary recess 104 may be used to engage thedetent 100 not engaged by therecess 102 to provide additional retentive engagement. Thedetents 100 are formed to be resiliently displaceable to allow for repeated release from, and engagement with, therecess 102. As will be appreciated by those skilled in the art, the positioning of thedetents 100 on thecap 30 and therecesses discharge element 18 may be reversed in any combination. One ormore stops 106 may be provided in addition to or alternatively from thedetent 100/recess 102 arrangement. Thestop 106 may be a protrusion, e.g., ring-shaped, on thedischarge element 18 which limits travel of thecap 30 relative thereto. - In addition,
indicia 41 may be provided to provide indication that thedispenser 10 is in the “off” and/or “on” state. For example, theindicia 41 may be located on both thebody 12 and the dispensingelement 18 and configured to provide a visual indication of the present state when aligned. - With reference to
FIG. 11 , to administer product, force, e.g. by manually squeezing a portion of the body 12 (e.g., the side wall 28), is applied to thebody 12 to cause deformation thereof.Surface configurations 40, such as dimples and/or other indicia, may be provided on thebody 12 to define target area(s) for force application. Thebody 12 is configured so that a threshold amount of deformation of thebody 12 results in a target reduction in volume of theclosed volume 14. The reduction in volume of theclosed volume 14 creates a pressure increase (FIG. 12 ) sufficiently to cause flowable material to be urged from thepouch 16 or theclosed volume 14, as appropriate, and through thedischarge opening 20 via thevalve 22. Thepouch 16, if used, contracts correspondingly as flowable material is discharged therefrom. - With using the
pouch 16, it is preferred that deformed portions of thebody 12 at the threshold amount of deformation be spaced from, so as to be out of contiguous contact with, theflexible pouch 16. Thus, direct contact may be avoided. It is preferred to have the pressure increase in theclosed volume 14 create a generally isobaric environment which acts evenly about thepouch 16 with no portions of thebody 12 directly pressing against thepouch 16 during a dispensing procedure. - Once a dose of flowable material has been administered, force is removed from the
body 12, e.g., releasing the squeezing force. With the force released, thebody 12 will seek to restore to its natural state. Under such force of restoration, the volume of theclosed volume 14 is caused to increase with venting via thevent 24. With restoration to the natural state, the dosing process can be repeated as desired. Once dosing is complete, thevalve 22 may be adjusted to a closed state, as needed. - As an additional feature, a
frame 42 may be provided which is located in theclosed volume 14 about at least portions of theflexible pouch 16. Theframe 42 may be configured to restrict the amount of deformation of thebody 12. For example, theframe 42 may be positioned to limit the extent of inward deflection of theside wall 28. Also, anovercap 44 may be provided to releasably mount to thebody 12. Preferably, theovercap 44 encompasses thedischarge opening 20, and possibly theapplicator 37, when mounted to thebody 12. Theovercap 44 may be partially or fully transparent. - As shown in
FIGS. 21 and 24 , theovercap 44 may be provided with a restingsurface 44 a. Thedispenser 10 may be caused to be inverted and rest upon the restingsurface 44 a with theovercap 44 mounted thereto, particularly where the flowable material is located in theclosed volume 14 without thepouch 16. This allows for the flowable material to be urged, under force of gravity, towards thedischarge passage 34 in anticipation of administration (against thevalve 22 if closed). With this arrangement, theclosed volume 14 is preferably vented in the inverted state. - Further, the
discharge element 18 may be configured to block thevent 24 to restrict venting with thedispenser 10 being in an “off” state. This further inhibits discharge from thepouch 16 or theclosed volume 14 if thebody 12 is inadvertently deformed (e.g., by accidental application of force) in addition to thevalve 22 being in a closed state.
