Description
- 1. Technical Field
- The present invention relates generally to valves used in conjunction with fluid containers or tubing, and more specifically to a valve associated with a fluid container and being actuated by a vacuum.
- 2. Background Prior Art
- Fluid containers are widely used throughout the world and come in many forms. Such fluid containers are made from a variety of materials and are used for numerous purposes. For example, containers are commonly used to contain fluids such as water, soft drinks, sports drinks, alcoholic beverages and the like for individual consumer use and consumption. Fluid containers are also widely used in other applications such as in a medical setting. For example, fluid containers are used in hospitals to provide nutritional fluids to patients who cannot eat solid food. Also fluid containers contain a variety of material used in industry and various mechanical arts such as engines and the like.
- A drawback to using such containers is the contents of the container can be easily spilled and, therefore, wasted. Not only are the contents lost but fluid spills can damage the surface the fluid contacts. Spilling of fluid contents is a particularly common occurrence for patients in a hospital setting. The patients can be under sedation or other medication that causes drowsiness or disorientation. The patients can also often drift into an involuntary unconscious state while consuming the nutritional products. This can result in spillage of the nutritional product over the patients' bedding requiring changing of the bedding and cleaning of the spillage.
FIG. 1 shows a variety of settings where fluid spills can occur. For example, fluids contained in drink pouches or drink boxes popular with children can be spilled through the straw supplied with the containers. Additionally, one is familiar with the problems arising with fluid spills in an industrial setting, wherein the spill of a caustic or dangerous chemical causes significant clean-up expense as well as placing workers in a potentially hazardous position. - Some fluid containers may be supplied with a closure such as a threaded cap. Such closures, however, normally must be open and/or closed manually by hand. This makes it difficult for consumers to use during certain activities such as running or cycling, or if consumers are carrying several other items that cannot be put down. Other closures have been developed that can be automatically actuated but are difficult to use. Such containers are also not economical to manufacture to be used with disposable fluid containers.
- The present invention is provided to solve these and other problems.
- The present invention provides a vacuum demand flow valve capable of dispensing a flowable material. In one preferred embodiment, the vacuum demand flow valve is attached to a drink container.
- According to one aspect of the invention, a vacuum demand flow valve has a member subject to a first force operative to keep the valve closed. The member is sensitive to an index pressure. The valve has an outlet at a second pressure, the index pressure provides a second force in opposition to said first force when a differential between the second pressure and the index pressure is provided to open the valve when the second pressure is sufficiently less than the index pressure to overcome the first force.
- According to another aspect of the invention, the valve provides a flowable material delivery device. The device has a first chamber at a first pressure wherein the first chamber defines an outlet in communication with said first chamber. The device has a second chamber at a second pressure at least substantially equal to the first pressure. The device has a valve member, indexed against a third pressure, operating to selectively place the first chamber into communication with the second chamber. The stop is operative to connect the second chamber to said first chamber when the first pressure is less than the third pressure.
- According to another aspect of the invention, a vacuum demand flow valve has a housing defining a passageway for a flowable material to pass therethrough. The passageway has a first volume when in a first position wherein the flowable material is not allowed to pass through the passageway. The passageway has a second volume less than the first volume when in a second position wherein the flowable material is allowed to pass through the passageway. The passageway is moveable from the first position to the second position by a vacuum applied through the passageway, wherein the difference between the volumes associates with the first position and the second position providing for the flowable material to retreat from the outlet of the valve and therefore be retained in the passageway.
- According to another aspect of the invention, the housing has a port member defining an external opening in communication with the passageway. The port member is adapted to be covered by a mouth of a user to apply the vacuum through the passageway. When the vacuum is applied, a force is applied to the housing in a first direction in response to the vacuum thereby placing the passageway in the second position, wherein flowable material flows through the passageway in a second direction. The vacuum can also be applied by a syringe or a pump in communication with the passageway.
- According to another aspect of the invention, a volume transition in the passageway between the second position and the first position causes flowable material to retreat into the passageway. An outlet is in communication with the passageway wherein the volume transition causes the flowable material to retreat from the outlet.
- According to another aspect of the invention, the port member has an orifice. The orifice is sized such that surface tension associated with the flowable substance across the orifice prevents the flowable material located within the passageway from passing through the orifice when the vacuum is removed from the passageway. The port member can also have a venturi structure defining the external opening.
- According to a further aspect of the invention, a valve has a port member defining an outer opening. The valve has a base member extending from the port member wherein the base member has an inner opening. A diaphragm extends between and is connected to the port member and the base member wherein a passageway is defined between the base member and diaphragm. The passageway is in communication with the outer opening and the inner opening. A stop member is connected to the diaphragm and has a plug that obscures the inner opening. The diaphragm is flexible from a first position wherein the passageway has a first volume and a second position wherein the passageway has a second volume. The plug is displaced from the inner opening in response to the movement of the diaphragm to the second position wherein a flowable substance can pass through the inner opening and passageway and outer opening.
- According to a further aspect of the invention, the valve is connected to a container having at least one flexible sidewall, a portion of the flexible sidewall comprises the diaphragm. An end of the base member is connected to an underside surface of the flexible sidewall.
- According to yet another aspect of the invention, a diaphragm is provided which is flexible so as to be responsive to a vacuum applied through the passageway. The diaphragm can also be flexible in response to an external force applied to the diaphragm to deflect the diaphragm.
- According to another aspect of the invention, the housing has a port member defining an external opening in communication with the passageway wherein the port member is adapted to be covered by a user's mouth to apply the vacuum.
- According to another aspect of the invention, the vacuum demand flow valve is attached in an opening of a fluid container.
- According to yet another aspect of the invention, a method of delivering a flowable material is disclosed. A first chamber is provided defining an outlet. A second chamber is provided that acts as a fluid reservoir. A valve index pressure is also provided. An opening is provided connecting the first chamber and the second chamber, and a valve is positioned in the opening. A first pressure is applied to the first chamber, the first pressure being less than the index pressure, wherein the valve moves from a closed position to an open position wherein flowable material flows through the outlet.
- According to a further aspect of the invention, a method of delivering a flowable material provides a housing defining a passageway for the flowable material to pass therethrough. The passageway has a first volume when in a first position wherein the flowable material is not allowed to pass through the passageway. The passageway has a second volume less than the first volume when in a second position wherein the flowable material is allowed to pass through the passageway. A vacuum is applied through the passageway wherein the passageway is moveable from the first position to the second position wherein the return of the passageway from the second position to the first position serves to retain the flowable material within the passageway by causing the flowable material to retreat up the passageway.

Theflange 68 cooperates with thelip 58 of theannular rim 56. Thediaphragm 14 is slightly under-sized as compared to theannular rim 56 wherein the elastomeric properties of thediaphragm 14 ensure a seal between thediaphragm 14 and therim 56. Once connected, thediaphragm 14 can be considered a portion of thehousing 12 that is flexible and deflectable from a first position to a second position to open thevalve 10 as described below as well as being capable of being biased towards the first position due to either the structural properties of the assembly or the mechanical properties of thediaphragm 14. Thus, in a preferred embodiment, thediaphragm 14 comprises the flexible portion of thehousing 12. - As also shown in
FIG. 5 , thestop member 18 is generally a plug member having aflange 70 at one end. Thestop member 18 depends from a central portion 64 of thediaphragm 14 and extends through theinternal opening 50. Theflange 70 abuts theunderside 52 of the intermediate wall 48 to define a closed valve position. Theflange 70 can be considered a plug that is radially extensive from thestop 18 and sized to close theinner opening 50. The plug, orflange 70 can be considered to be located toward an upstream side of the valve from the stop. The upstream side of the valve can be considered generally at thesecond chamber 42 and the downstream side of the valve can be generally considered at thefirst chamber 40. In a preferred embodiment, thestop member 18 and thediaphragm 14 can be integrally molded together so as to form the valve member aforedescribed. As described in greater detail below, the resiliency of thediaphragm 14 biases thestop member 18 against theinternal opening 50 to define a closed valve position. Theflange 70 abuts theunderside surface 52 of the internal wall 48. - In one preferred embodiment, the
valve 10 utilizes thediaphragm cover 20. Thediaphragm cover 20 is positioned over thediaphragm 14. Thediaphragm cover 20 has acollar 65 that fits around theflange 68 of thediaphragm 14. Thediaphragm cover 20 can fit within thegroove 62 at a front portion of thevalve 10. Thediaphragm cover 20 is sized to assist in the compression of thediaphragm 14 around theannular rim 56. Thediaphragm cover 20 helps protect thevalve 10 from accidental activation. As shown inFIGS. 2 and 3 , if desired, thevalve 10 can also be equipped with thecap 21 that is press-fit over theport member 44. A tamper evident sealingmember 72 can also be included. The tamper evident sealingmember 72 seals thecap 21 to thehousing 12 and gives a visual indication of whether thevalve 10 has been tampered with or previously manipulated. It is understood that the valve components can be connected through a variety of processes including radio frequency or ultrasonic welding as well as solvent bonding or other methods as appropriate for the materials used. - As discussed, in one preferred embodiment, the
valve 10 is attached to afluid container 11. The container may either be formed from a single web or may have a flexiblefirst sidewall 22 and flexiblesecond sidewall 24. In the configuration and as shown inFIGS. 2, 3 , and 4, thevalve 10 is inserted between peripheral edges of thesidewalls lower wall 34 is generally connected to thesecond sidewall 24. - As shown in
FIG. 5 , thecontainer 11 is shown in a configuration having a single circumferential sidewall as may be formed by blow molding and the like. - Prior to operation of the
valve 10 thecap 21 is secured to thehousing 12 by the tamperevident strip 72. As shown inFIGS. 3 and 4 , the tamperevident strip 70 is peeled away and thecap 21 removed to expose theport member 44. -
FIGS. 5-7 disclose operation of thevalve 10 In an initial state, and as shown inFIG. 5 , thevalve 10 is in a closed position wherein thestop member 18 is biased against theunderside surface 52 to close theinner opening 50. The valve member is subject to a first force operative to keep thevalve 10 closed. In this first position, thefirst chamber 40 of thepassageway 26 has a first volume V1. An external surface 15 of thediaphragm 14, and therefore the combination of thediaphragm 14, thestop 18, and theflange 70, which in combination can be referred to as a valve member, is generally subject to, and is sensitive to, an index pressure PI. The index pressure could be, for example, ambient pressure with thecap 20 being vented, or some other pressure resident in the interstice between thediaphragm 14 and thecap 20. The valve member is indexed against this index pressure PI. Thefirst chamber 40 is also generally subjected to a pressure P1 which could be approximately equal to or greater than the index pressure PI. - The
second chamber 42 and thecontainer 11 may also be at an ambient pressure, or at some pressure substantially at or above the index pressure PI. The pressure in thesecond chamber 42 andcontainer 11 may be referred to as PC. The pressure in thecontainer 11 will not be substantially less than the pressure in thefirst chamber 40. As shown inFIG. 6 , a user places their mouth over theport member 44 and reduces the pressure through thefirst chamber 40 of thepassageway 26. This reduced pressure can be referred to as P2. The partial vacuum provides a pressure less than the index pressure. As shown inFIG. 6 , the vacuum acts on a lower surface 74 of thediaphragm 14 causing the index pressure on the upper surface of the diaphragm to apply a force on thediaphragm 14 equal to the difference between the index pressure and the pressure of the partial vacuum times the area of thediaphragm 14, drawing it downwards. This moves thestop member 18 downwards in the direction of arrow A, and into thesecond chamber 42 towards thecontainer 11. Theflange 70 is spaced away from theinner opening 50 thus opening thevalve 10. This occurs when the force applied overcomes a first force associated with thediaphragm 14 that maintains thestop member 18 to close theinternal opening 50. This force may be, preferedly, a resilient spring force associated with the diaphragm structure or, in other embodiments, be due to an index pressure substantially below the initial pressure in the first chamber acting on thediaphragm 14; or a force due to pressure in thecontainer 11 acting on the area ofplug 70; or may be applied by an external means as exemplified by thespring 164 inFIG. 18 . In this second position, thefirst chamber 40 of thepassageway 26 has a second volume V2. The second volume V2 is less than the first volume V1 as thediaphragm 14 is moved closer to the intermediate wall 48. It is also understood the area between thediaphragm 14 and thecover 20 increases to a volume of V3 in this position. In this position, the flowable material such as a drink fluid, as shown, is allowed to flow from thecontainer 11, through theinner opening 50 in the direction of arrow B, through thepassageway 26 and out thefirst opening 28 to be consumed by the user. Thus, when a vacuum is applied, a force is applied to thehousing 46 in a first direction (arrow A) in response to the vacuum thereby placing the passageway 48 in the second position, wherein fluid flows through the passageway in a second direction generally shown as arrow C inFIG. 6 . Thus, when a differential between the second pressure and the index pressure is provided to the valve member, thevalve 10 opens when the second pressure is sufficiently less than the index pressure to overcome the first force operative on the valve member. Thecontainer 11 is adapted to supply constant pressure when thevalve 10 is open, such as aflexible container 11 or a rigid container having a vent. It is understood thevalve 10 is operable even if thecontainer 11 is pressurized. - It can be further understood that the valve member is subject to a first force, as described hereabove, operative to keep the
valve 10 closed. The valve member, i.e., the combination of thediaphragm 14, thestop 18, and theflange 70, supplies this biasing force as aforesaid. The valve member is sensitive to the index pressure. Theoutlet 28 of thevalve 10 is subject to a second pressure. The index pressure provides a second force in opposition to the first force when a differential between the second pressure and the index pressure is provided to open the valve such that the second pressure is sufficiently less than the index pressure, multiplied by the area of the valve member, to overcome the first force. As shown inFIG. 6 , the vacuum acts on a lower surface 74 of thediaphragm 14 causing the index pressure on the upper surface of the diaphragm to apply a force on thediaphragm 14 equal to the difference between the index pressure and the pressure of the partial vacuum times the area of thediaphragm 14, drawing it downwards. This moves thestop member 18 downwards in the direction of arrow A, and into thesecond chamber 42 towards thecontainer 11. Theflange 70 is spaced away from theinner opening 50 thus opening thevalve 10. This occurs when the second pressure is sufficiently less than the index pressure wherein the force applied overcomes the resilient spring force or other sources of the force associated with thediaphragm 14 that biases thestop member 18 to close theinternal opening 50. - As shown in
FIG. 7 , once the vacuum is removed, thevalve 10 returns to the first or closed position. Thus, when the second pressure is substantially equal to or greater than the index pressure, thevalve 10 closes. The resiliency of thediaphragm 14 biases thestop member 18 against theunderside surface 52 of the intermediate wall 48 to close theinner opening 50 and therefore thevalve 10. Fluid that passes through theport member 44, after the vacuum has been removed, is consumed by the user. The change between the first volume V1 and the second volume V2 provides for an action that serves to withdraw the fluid from theoutlet 28 back into theoutlet passageway 29 such that the linear distance the fluid is withdrawn into theoutlet passageway 29 is equal to the difference between the volume V2 and the volume V1 divided by the area of theoutlet 28 which is sufficient to draw the fluid toward thepassageway 26 and away from theoutlet 28. Fluid that remains in thepassageway 26 at the reduceddiameter orifice 46 when the vacuum is removed, however, does not drip from thevalve 10. Theorifice 46 is sized in theport member 44 such that surface tension ST of the fluid across theorifice 46 maintains the fluid in the passageway 48 once the vacuum is removed. The molecules of the fluid will experience an inward force from the other fluid molecules wherein the fluid will act like an elastic sheet across theorifice 30. Molecules at the edges of the orifice will be attracted to the surfaces of thehousing 12 defining theorifice 30. Thus, due to surface tension ST of the fluid, the fluid already in thepassageway 26 cannot pass through theorifice 46 until a vacuum is again applied. - It can be understood that in this valve configuration as disclosed in
FIGS. 2-7 , thesecond chamber 42 of thepassageway 26 of thevalve 10 is in communication with thecontainer 11. Thesecond chamber 42 can include thecontainer 11. Thestop member 18 and theinner opening 50 can define a simple valve. In an initial state, the upper surface 15 of thediaphragm 14 is subject to an index pressure PI. In one embodiment, the index pressure PI can be ambient pressure. Also in the initial state, thefirst chamber 40 of thepassageway 26 could also be under some different first pressure PI or the index pressure PI. Thesecond chamber 42 would be under a second pressure PC which also could typically be ambient pressure. Thecontainer 11 is also initially under the container pressure PC. This pressure could be ambient pressure. When a partial vacuum is applied, thefirst chamber 40 is now under a second pressure P2 that is less than the index pressure PI. In this state, the valve moves from a closed position to an open position wherein the fluid is allowed to flow through theouter opening 50. Thus, the valve operates to selectively place thefirst chamber 40 into communication with thesecond chamber 42. Accordingly, a differential pressure is applied across thediaphragm 14 causing thevalve 10 to open and allow fluid to pass through theopening 50. In one preferred embodiment, the pressure differential occurs from ambient pressure, wherein the index pressure is at ambient pressure and the housing chamber is subjected to a negative pressure. Thus, thevalve 10 is actuated by applying a pressure less than ambient pressure. It is understood that a pressure differential could also be applied from an initial pressure not equal to ambient pressure. One could also consider the index pressure a third pressure wherein the first chamber is subject to a first pressure and the second chamber is subject to a second pressure at least substantially equal to the first pressure. The valve is indexed against the third pressure. The valve operates to selectively place the first chamber into communication with the second chamber when the first pressure is less than the third pressure, or index pressure.FIG. 8 further illustrates the pressures, and forces associated with the pressures, that act on the valve member during operation of thevalve 10. The index pressure exerts an index force FI on an outer surface of thediaphragm 14. Prior to operation, the first chamber has a first pressure P1 and a first force F1 acting on an inner surface of thediaphragm 14 serving to balance the remaining forces acting on the valve. The container pressure PC and container force FC also acts on the valve member at theplug 70. A biasing force FB also acts on the valve member and is, in certain embodiments, supplied by the structure ofdiaphragm 14. When the first pressure P1 is reduced to a new pressure P2, a force F2 (less than F1) is applied to thediaphragm 14. The resultant force acting on thediaphragm 14 to open thevalve 10 can be represented by the following vector formula: FR (resultant force)=AD(PI−P2)−AP(PC)−FB wherein AD is the area of thediaphragm 14 and AP is the area of theplug 70. - It is understood that the
valve 10 can operate without utilizing thediaphragm cover 20.FIG. 8 discloses a simplified version of thevalve 10 wherein adiaphragm cover 20 is not used. Thediaphragm 14 can comprise a flexible portion of thehousing 12. Upon actuation, this housing portion would flex to move thestop member 18 away from theinner opening 50. - It is further understood that the vacuum to actuate the
valve 10 is typically applied by a user reducing the pressure through thepassageway 26. The vacuum could also be applied by other means such as asyringe 51 as shown inFIG. 9 . A vacuum could also be applied by a pump or other mechanical means. Finally, it is understood that the designations of “first” and “second” with respect to the chambers, pressures and valve positions can be interchanged. - In an alternative method of valve actuation, a user can depress the
diaphragm 14 through thecover 20 to move thestop member 18 away from theinner opening 50. Fluid is then allowed to pass through thepassageway 26 and out theouter opening 28. - It is understood that the
valve 10 can be incorporated into a tubing. A portion of the tubing can be flexible and provide thediaphragm 14. An opposite portion of the tubing can be provided with theopening 50 to be communication with thecontainer 11. Thestop member 18 can be provided between thediaphragm 14 andopening 50. - It is further understood that the
valve 10 could be constructed with multiple chambers and diaphragms or connected to a manifold designed to be in communication with separate chambers of a multi-chambered container. Different fluids, stored separately, could then be consumed together. - The valve components can be made from a variety of materials. The materials can be selected based on the intended use of the
valve 10. In one embodiment, such as the valve being used with drink containers, the valve components can be made from a variety of polymers or other structurally suitable materials. Other materials are also possible. The choice of materials is only related to the fluid and use the valve is to be applied to. For example, should this valve be used in the fuel or oxidizer supply section of a rocket engine with an injection pump providing a partial vacuum and the index pressure externally applied; the valve member and housing may be made out of stainless steel. -

Thevalve 150 is operated as described above. -
FIGS. 21-25 disclose yet another embodiment of the vacuum demand valve of the present invention. This valve, generally referred to with thereference numeral 200, is shown attached to a flexiblefluid container 211. It is understood that thevalve 200 can be used with various types of containers that contain a flowable material or substance. The structure of thevalve 200 will first be described followed by a description of the operation of thevalve 200. - As shown in
FIG. 24 , thevalve 200 generally includes aport member 212, a first member ordiaphragm member 214, a second member orbase member 216, astop member 218, adiaphragm cover 220 and acap 221. Thevalve 200 is adapted to be connected to thecontainer 211 that has afirst sidewall 222 and asecond sidewall 224. Thevalve 200 allows for dispensing flowable materials from thecontainer 211. As discussed in greater detail below, thediaphragm member 214 is a flexible member that can be actuated by a user through the use of a vacuum pressure or a positive, external force. - As further shown in
FIGS. 24 and 25 , theport member 212 is generally a tubular structure and defines an outlet orouter opening 226. Theport member 212 is sized such that a user's mouth can fit comfortably over theport member 212. In one preferred embodiment as shown inFIG. 23 , theport member 212 has an elliptical shape. Theport member 212 has a disk-shaped member 228 having an orifice 230 (FIG. 24 ). - The
base member 216 is an elongated member that extends from a bottom portion of theport member 212. Thebase member 216 has a first end 232 that extends from theport member 212. Asecond end 234 of thebase member 216 is connected to one end of thediaphragm 214 at anintermediate location 236 to be described in greater detail below. Thebase member 216 has aninner opening 238. Theinner opening 238 will be in communication with thefluid container 211. Thediaphragm 214 is a flexible member having oneend 240 extending from anupper portion 242 of theport member 212. Thediaphragm 214 has a second end 244 that is connected to theend 234 of thebase member 216 at theintermediate location 236. As will be discussed in greater detail below, in one preferred embodiment when thevalve 200 is attached to aflexible container 211, thediaphragm 214 will comprise a portion of one of theflexible sidewalls 222. Thebase member 216 anddiaphragm 214 collectively comprise ahousing 246 of thevalve 200. A portion of thehousing 246 is flexible from a first position to a second position to open thevalve 200. In a preferred embodiment, thediaphragm 214 comprises the flexible portion of thehousing 246. Theport member 212 could also be included as part of thehousing 246. Thebase member 216 anddiaphragm 214 also collectively define apassageway 248 of thevalve 200. - The
stop member 218 is positioned generally between thediaphragm 214 andbase member 216 within thepassageway 248. Thestop member 218 has anarm 250 and aplunger 252 having aplug 254 at a distal end of theplunger 252. Thearm 250 is hingedly connected to theport member 212 by aflexible strap 256. Theplunger 252 is connected to a distal end of thearm 250. Theplunger 252 and thearm 250 are connected to abottom surface 258 of thediaphragm 214. Theplug 254 is positioned through theinner opening 238 and abuts a bottom surface 260 of thebase member 216 to close theinner opening 238. Theplunger 252 further has a pair ofresilient members 262. Theresilient members 262 bias theplug 254 against the bottom surface 260 of thebase member 216 so that theplug 254 abuts against the bottom surface 260 to close theopening 238. - In one preferred embodiment, the
valve 200 utilizes thediaphragm cover 220. Thediaphragm cover 220 is positioned over thediaphragm 214. Thediaphragm cover 220 has a collar 264 positioned around theport member 212 and connected proximately thereto. An opposite end of thediaphragm cover 220 is connected to thediaphragm 214 at theintermediate location 236. Thediaphragm cover 220 has avent 266. If desired, thevalve 200 can also be equipped with thecap 221 that fits over theport member 212. A tamper evident sealingmember 270 can also be included. The tamper evident sealingmember 270 seals thecap 221 against the collar 264 and gives a visual indication of whether thevalve 200 has been tampered with or previously manipulated. - As discussed, in one preferred embodiment, the
valve 200 is attached to afluid container 211 having flexiblefirst sidewall 222 and flexiblesecond sidewall 224. In this configuration and as shown inFIGS. 24 and 25 , thevalve 200 is inserted between peripheral edges of thesidewalls end 234 of thebase member 216 is connected to an underside surface 272 of thefirst sidewall 222 at theintermediate location 236. Thefirst sidewall 222 extends further wherein its peripheral edge is connected to thevalve 200 proximate theport member 212. In this configuration, the portion of thefirst sidewall 222 extending from theintermediate location 236 to the connection proximate theport member 212 comprises thediaphragm 214. The bottom orsecond sidewall 224 is connected proximate thebase member 216 at theport member 212 to seal thevalve 200 to thecontainer 211. Theinner opening 238 is in communication with the inner chamber of thecontainer 211 defined by theflexible sidewalls valve 200 could have adiaphragm 214 constructed from a member separate from thesidewall 222. - Prior to operation of the
valve 200, thecap 221 is secured to thevalve 200 by the tamperevident strip 270. As shown inFIGS. 22 and 23 , the tamperevident strip 270 is peeled away and thecap 221 is removed to expose theport 212. -
FIGS. 24 and 25 generally disclose operation of thevalve 200. In an initial state, and as shown inFIG. 24 , thevalve 200 is in a closed position wherein theplug 254 is biased against the bottom surface 260 to close theinner opening 238. In this first position, thepassageway 248 has a first volume V1. The volume extends generally from the junction of thebase member 216 anddiaphragm 214 to theport member 212. A user places their mouth over theport member 212 and sucks to provide a partial vacuum through thepassageway 248. The vacuum is a pressure less than an ambient pressure. As shown inFIG. 25 , the vacuum acts on thelower surface 258 of thediaphragm 214 wherein the force associated with the index pressure forces thediaphragm 214 downwards. This moves theplunger 252 downwards in the direction of arrow A, wherein theplug 254 is spaced away from theinner opening 238 thus opening thevalve 200. In this second position, thepassageway 248 has a second volume V2. The second volume V2 is less than the first volume V1 as the diaphragm moved closer to thebase member 216. It is also understood the area between thediaphragm 214 and thecover 220 increases to a volume of V3 in this position. In this position, the fluid is allowed to flow from thecontainer 211, through theinner opening 238 in the direction of arrow B, through thepassageway 248 and out theorifice 230 andouter opening 226 to be consumed by the user. Thus, when a vacuum is applied, a force is applied to thehousing 246 in a first direction (arrow A) in response to the vacuum thereby placing thepassageway 248 in the second position, wherein fluid flows through the passageway in a second direction generally shown as arrow C inFIG. 25 . - Once the vacuum is removed, the
valve 200 returns to the first position. Theresilient members 262 bias theplug 254 against the bottom surface 260 of thebase member 216 to close theinner opening 238 and therefore thevalve 200. Fluid that passes through theorifice 230, after the vacuum has been removed, is consumed by the user. Fluid that remains in thepassageway 248 when the vacuum is removed, however, does not drip from thevalve 200. The change between the first volume V1 and the second volume V2 provides for an action that serves to withdraw the fluid from theoutlet 238 back into the outlet passageway 229 such that the linear distance the fluid is withdrawn into the outlet passageway 229 is equal to the difference between the volume V2 and the volume V1 divided by the area of theoutlet 238 which is sufficient to draw the fluid toward thepassageway 248. Theorifice 230 in theport member 212 is sized such that surface tension of the fluid across theorifice 230 maintains the fluid in thepassageway 248 once the vacuum is removed. The molecules of the fluid will experience an inward force from the other fluid molecules wherein the fluid will act like an elastic sheet across theorifice 230. Molecules at the edges of the orifice will be attracted to the surface of the disk-shaped member 228 defining theorifice 230. Thus, due to surface tension of the fluid, the fluid already in thepassageway 248 cannot pass through theorifice 230 until a vacuum is again applied. In an alternative embodiment shown inFIG. 25 , theport member 12 can have aventuri structure 231 generally at theport member 212. - It can be understood that in this valve configuration as disclosed in
FIGS. 21-25 , thepassageway 248 of thevalve 200 defines a first chamber while thecontainer 211 defines a second chamber. Theplug 254 andinner opening 238 define a simple valve. In an initial state, the upper surface of thediaphragm 214 is subject to a first pressure, or index pressure PI. Thepassageway 248 could also be subject to the index pressure PI or some other first pressure. In one particular embodiment, the index pressure could be ambient pressure. Thecontainer 211 is subject to a container pressure PC. The container pressure could also be at ambient pressure. When a partial vacuum is applied by a user as shown inFIG. 25 , the first chamber defined by thepassageway 248 is subjected to a second pressure P2 that is less than the index pressure PI. In this state, the valve moves from a closed position to an open position wherein the fluid is allowed to flow through theouter opening 26. In one preferred embodiment, the index pressure PI represents ambient pressure, which in an equilibrium state is present in thepassageway 248 and thecontainer 211. In this initial state (FIG. 24 ), the index pressure PI is generally under ambient pressure and theplug 254 closes theopening 238. When the second pressure P2 is applied to thepassageway 248 that is less than ambient pressure, a vacuum is present. This results in a force acting on thediaphragm 214 as explained above drawing the diaphragm downwards wherein theplug 254 moves away from theopening 238 allowing fluid to pass through theopening 238. Thus, a differential pressure is applied across thediaphragm 214 causing thevalve 200 to open and allow fluid to pass through theopening 238. In one preferred embodiment, the pressure differential occurs from an index pressure that is ambient pressure. Thus, thevalve 200 is actuated by applying a pressure less than ambient pressure. It is understood that a pressure differential could also be applied from an index pressure not equal to ambient pressure. It is also understood that the vacuum is typically applied by a user reducing the pressure through the passageway. The vacuum could also be applied by other means such as a syringe. A vacuum could also be applied by a pump or other mechanical means. Finally, it is understood that the designations of “first,” “second” and “third” with respect to the chambers, pressures and valve positions can be interchanged. - In an alternative method of valve actuation, a user can depress the
diaphragm 214 through thecover 220 to move theplug 254 away from theinner opening 238. Fluid is then allowed to pass through thepassageway 248 and out theouter opening 226. - The valve components can be made from a variety of materials. In preferred form of the invention, the valve components are made from an injection-molded process wherein the
port member 12, base member 16 and portions of thestop member 18 are integrally molded. It is understood, however, that the valve components can be formed separately and connected to one another. - It is understood that the
valve 10 can be incorporated into a tubing. A portion of the tubing can be flexible and provide thediaphragm 14. An opposite portion of the tubing can be provided with an opening to be in communication with thecontainer 11. A stop member can be provided between thediaphragm 14 and opening. - Thus, a device 10 (as well as the other disclosed devices) is provided that is simple in construction and use. As shown in
FIG. 26 , thevalve 10 connected to acontainer 11 can be easily actuated by a user merely by applying a vacuum through theport member 12. Fluid is consumed as needed and will not drip from thevalve 10. In addition, due to the construction of thedevice 10, fluid cannot be expelled through thevalve 10 by squeezing theflexible sidewalls container 11. To the contrary, squeezing thesidewalls plug 70 is forced further against the intermediate wall of the housing. Thus, if thecontainer 11 is accidently compressed, fluid will not spray through thevalve 10. - As shown in
FIGS. 27 and 28 , thevalve 10 can be constructed wherein, for example, thediaphragm cover 20 can have a distinctive shape 180 (FIGS. 27 and 28 ) or an indicia-bearing surface 182 (FIG. 28 ) for promotional purposes or to provide for branding opportunities. - Containers utilizing the flowable material delivery device/valve of the present invention have a broad variety of uses and applications. The
valve 10 is ideal for using with hot or cold drinks, as well as non-carbonated drinks. Users can easily carry such acontainer 11 on their person (FIGS. 29 and 30 ).Containers 11 holding, for example, juice or milk, can also be used for children and infants (FIGS. 29 and 32 ). Thecontainers 11 can also have ahanger member 184 associated therewith. As shown inFIGS. 32 and 33 a, thehanger member 184 may include aclamp 186 and aband 188 connecting theclamp 186 to thecontainer 11. Theclamp 186 can be removably affixed to a support member. The support member can include a plurality of different types of members such as in a vehicle (FIG. 33 a) or a stroller (FIG. 32 ) such as for an infant. Thecontainer 11 can then be hung from the support member to be grasped by a user. As shown inFIG. 34 c, theclamp 186 can also be directly attached to thecontainer 11. Thecontainers 11 can also be utilized in a number of different recreational settings (FIGS. 31 and 35 ). Thecontainers 11 are also ideal when taking part in active sporting activities (FIGS. 34 a-d). As shown inFIG. 34 b and 34 d, thecontainer 11 could have aflexible tubing 190 attached thereto and avalve 10 attached to a distal end of thetube 190 wherein thetube 190 can be easily accessed hands-free such as when cycling or running. Thecontainer 11 can also be grasped with a single hand and the fluids consumed without further manual manipulation of the valve 10 (SeeFIG. 26 ). Thecontainers 11 are further ideal to use when traveling (FIGS. 33 a-b). - The
container 11 can further be designed to stand upright in a predetermined position. As shown inFIG. 33 b, thecontainer 11 can also have acarrier 192 that can support thecontainer 11 in a predetermined position. In one embodiment, thecarrier 192 can have a base 194 andsidewalls 196. Thecarrier 192 may also have ahandle 198. Finally, as shown inFIGS. 36 a and 36 b, thecontainer 11 can be used by patients in a hospital setting. As further shown inFIG. 36 b, anelongated tubing 199 can be attached to thecontainer 11 with thevalve 10 on the distal end of the tube. Uses also comprehended by the scope of the invention include storage and dispensing of industrial chemicals, medicaments or any other flowable material. - The
valve 10 provides several benefits. Thecontainer 11 andvalve 10 are low-cost and designed for single-use consumption wherein thecontainer 11 andvalve 10 can be discarded when thecontainer 11 is empty. Thevalve 10, however, could also be used in multi-use applications. Thevalve 10 is suction-activated wherein the user can drink through thevalve 10 as easily as with a conventional straw. The housing structure and valve function also prevent dripping from the valve. The structure of thevalve 10 prevents fluid from being drawn back into the container once through the internal opening. The structure of thevalve 10 also resists pressure from thecontainer 11 and cannot be accidently activated. Thevalve 10 is not required to be recapped once opened as thevalve 10 returns to its closed position upon non-use. The valve components are easily manufactured such as by an injection-molded process in one preferred embodiment. Because the valve can be constructed from certain injection-moldable materials, the valve can be operable through a broad range of temperatures and for extended periods of time. - It will be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. The present embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
