Abstract
A vent and fluid transfer fitment (30) for sealing and trans- ferring a fluid from an inverted fluid-filled container (16) without premature leakage to a receiver attachment (22), has a transfer check valve (12) and a venting check valve (13) which are preferably duck- bill valves. The transfer check valve is attached to the fitment for allowing fluid to be transferred from the container when the receiver attachment engages the transfer check valve. The venting check valve is also attached to the fitment for allowing air to displace the fluid as the fluid exits the container, wherein both the transfer check valve and the venting check valve have an inherent sealing pressure created by the static pressure of the fluid within the container. In addition, the inherent sealing pressure of the venting check valve is less than the inherent sealing pressure of the transfer check valve which allows air to enter the container due to the pressure differen- tial created as the fluid is displaced.

INTEGRATED VENT AND FLUID TRANSFER FITMENT
Field of the Invention The present invention relates to an improved vent and fluid transfer fitment, and more particularly, to a vent and fluid transfer fitment for a fluid-filled ~5 container that allows the contents of the container to be vented while bein g transferred ve~ithout the contents spilling when the container is inverted.
Background of the Invention Conventional vent and fluid transfer systems utilize a non-inverted 20 container having a dip tube for transferring fluid from the container. The containee is ypically vented using a hole in the top of the container. Hoevever, the fluid within these systems leak evhen the container is in an inverted orientation.
Another approach has been to use vented trigger sprayers to dispense fluids From a container. These systems typically use a switch mechanism to close the vent 25 except when the unit is dispensing. However, leakage ran occur if the unit is actuated when the container is in a sideways or inverted orientation.
A third approach has been to provide a container with walls that are sufficiently thin such that they collapse under the vacuum pressure created by the removal of the container's contents. This type of system eliminates the need to allow air into the 3o container to displace the fluid that is dispensed from the container.
However, the system does not alloy;~ a steady fluid flow from the container as the fluid flow will decrease as the Vacuum pressure within the container increases.
Therefore, ~a~hat is needed is an improved vent and fluid transfer fitment that allows fluid to be uniformly transferred from an inverted container without leaking 35 and evhich vents the container such that the displaced fluid is replaced by air.

3 Referring to FIGS. i and 2, the pxeferred vent and fluid transfer ~tnnent 10 comprises a transfer fitment 11 having a transfer check valve 12 and a venting check valve 13 and is shown in an unassembled (FIG. i) and an assembled (FIG. 2) configuration. The transfer fitment 1 I is preferably a single molded part that contains both the transfer check valve 12 and the venting check valve ,13 (FIGS. la and 1b).
However, the fitment 11 rnay include a cap or closure I4 in which a separate transfer check valve 12 and venting check valve I 3 are inserted (FIG. 1 c) without deviating from the intent of the invention.
In addition, the preferred transfer fitment 1 I may have support ribs 1 S
which add stability to the transfer fitment 1 I and particularly to the transfer check valve 12 as shown in FIGS. 1 a and 1 b. The transfer check valve 12 and the venting check valve 13 are preferably duckbill valves which have an inherent sealing pressure and which are oriented in the same direction. However, the valves 12 and 13 may comprise a variety of valves without deviating from the intent of the invention. For example, the check valves 12 and 13 may comprise umbrella valves, ball and spring check valves or a slit valve. In addition, the venting check valve 13 may be located elsewhere on the bottle 1 b and/or in a different orientation without deviating from the intent of the invention. The fitment 11, the transfer check valve 22, and the venting check valve 13 preferably comprise am elastomeric material.
The preferred transfer duckbill valve 12 has an open end 12a and a closed "beak" end 12b which remains in a closed position when the transfer duckbill valve 12 is in the relaxed state (FIG. 1 a). The preferred venting duckbill valve 13 also has an open end 13a and a closed ''beak" end 13b which remains in a closed position when the venting duckbill valve 12 is in the relaxed state (FIG. la).
The preferred fitment 11 is attached to a fluid f lied bottle 1 G, specifically an opening 17, by snapping a snap bead i8 of the fitment 1I into a snap rim 19 of the bottle 16. However, the fitment 1 I may be attached to the bottle 16 using screw threads 20 on a bottle finish 21 as is well known in the art. After attaching the preferred fitment 11 to the bottle 16, the battle 16 may be inverted without allowing the contents of the 3o fluid within the hottle 16 to exit due to the valves 12 and 13 being in the relaxed state as seen in FIG. 1 a and the ends 12b and 13b remaining closed.
The preferred fitment I l and bottle I6 assembly is connected to a receiver attachment 22 which has a probe tip' 23 and an air vent groove 24. The probe tip 23 has a first and second open end 23a and 23b, respectively. The first open end 23a of the probe tip 23 deforms and opens the "beak" end 12b of the transfer duckbill valve 12 upon insertion into the open end 12a (FIG. 2). The second open end 23b of the probe 23 is WO 00/27746 PC'T/t1S99I25576 ~ :~:'
However, the fitment 11 rnay include a cap or closure I4 in which a separate transfer check valve 12 and venting check valve I 3 are inserted (FIG. 1 c) without deviating from the intent of the invention.
In addition, the preferred transfer fitment 1 I may have support ribs 1 S
which add stability to the transfer fitment 1 I and particularly to the transfer check valve 12 as shown in FIGS. 1 a and 1 b. The transfer check valve 12 and the venting check valve 13 are preferably duckbill valves which have an inherent sealing pressure and which are oriented in the same direction. However, the valves 12 and 13 may comprise a variety of valves without deviating from the intent of the invention. For example, the check valves 12 and 13 may comprise umbrella valves, ball and spring check valves or a slit valve. In addition, the venting check valve 13 may be located elsewhere on the bottle 1 b and/or in a different orientation without deviating from the intent of the invention. The fitment 11, the transfer check valve 22, and the venting check valve 13 preferably comprise am elastomeric material.
The preferred transfer duckbill valve 12 has an open end 12a and a closed "beak" end 12b which remains in a closed position when the transfer duckbill valve 12 is in the relaxed state (FIG. 1 a). The preferred venting duckbill valve 13 also has an open end 13a and a closed ''beak" end 13b which remains in a closed position when the venting duckbill valve 12 is in the relaxed state (FIG. la).
The preferred fitment 11 is attached to a fluid f lied bottle 1 G, specifically an opening 17, by snapping a snap bead i8 of the fitment 1I into a snap rim 19 of the bottle 16. However, the fitment 1 I may be attached to the bottle 16 using screw threads 20 on a bottle finish 21 as is well known in the art. After attaching the preferred fitment 11 to the bottle 16, the battle 16 may be inverted without allowing the contents of the 3o fluid within the hottle 16 to exit due to the valves 12 and 13 being in the relaxed state as seen in FIG. 1 a and the ends 12b and 13b remaining closed.
The preferred fitment I l and bottle I6 assembly is connected to a receiver attachment 22 which has a probe tip' 23 and an air vent groove 24. The probe tip 23 has a first and second open end 23a and 23b, respectively. The first open end 23a of the probe tip 23 deforms and opens the "beak" end 12b of the transfer duckbill valve 12 upon insertion into the open end 12a (FIG. 2). The second open end 23b of the probe 23 is WO 00/27746 PC'T/t1S99I25576 ~ :~:'
4 preferably connected to a 'tube 25 for guiding the fluid from the bottle 16 to a purxrp or reservoir (not shown). However, the tube 25 and receiver attachment 22 may be formed as a single piece without deviating from the intent of the invention.
When the bottle 16 is in an inverted orientation {FIG. 1 a), the internal static pressure acting against the "beak" end 12b and I3b of the duckbill valves 12 and 13, respectively, will seal the valves 12 and I3 tightly. Therefore, the valves I2 and 13 prevent fluid from prematurely flowing out of the inverted bottle I6 until the probe 23 of the receiver attachment 22 in inserted within the transfer duckbill valve 12 Upon insertion of the receiver attachment's probe 23 into the transfer duckbill valve 12, the fluid is transferred by gravity through the probe tip 23 as it deforms and opens the transfer duckbill valve 12. As a result, a vacutun (sub-atmospheric) pressure is created within the bottle 16. When the vacuum is sufficient to overcome the sealing pressure on the venting valve I3, a bubble of air will be drawn into the bottle I6 along an air flow path 26 (FIG. 2) which quickly relieves the vacuum pressure created within the bottle 16 by the fluid exiting and resumes the sealing pressure.
Preferably, the sealing pressure of the venting duckbill valve 13 is less than the sealing pressuxe of the transfer duckbill valve 12. As a result, the vacuum (sub-atmospheric) pressure created within the bottle 16 will cause the venting duckbill valve 13 to open and not the transfer duckbill valve 12 beyond the opening created by the displacement of the valve 12 due to the probe 23.
The air vent groove 24 in the receiver attachment 22 ensures that air can reach the venting duckbill valve 13 and be drawn into the bottle 16 when sufficient sub-atmospheric pressure is generated by the transfer of the fluid from the bottle 16. As the probe tip 23 is pushed through the transfer duckbill valve 12 (F'IG. 2), the probe 23 seals along the inside wall of the duckbill valve I2. In the fully seated position (FIG. 2), the probe 23 extends through the open end 12a of the duckbill valve 12 and provides a fluid path to the tube 25.
Referring to FIGS. 3a-3c, the first alternate vent and fluid transfer fitment preferably comprises the transfer fitment 11 having a transfer check valve 27 (FIGS. 3a 3o and 3b) and a venting check valve 28. The alternate transfer check valve 27 is preferably a septum valve and the alternate venting check valve 28 is preferably an umbrella valve, both of which have an inherent sealing pressure and which are oriented in the same direction. As in the preferred embodiment, the alternate venting check valve 2$ may be located elsewhere on the bottle 16 and/or in a different orientation without deviating from the intent of the invention. The septum valve 27 is attached to the container 16 using a fitment 30.
WO 00/27746 PCTlgJS99/25576- :~' In addition, the septum valve 27 and the umbrella valve 28 may be formed from a single piece as shown in FIG. 3c. In this way, the probe 23 is inserted through a slit 29 in the umbrella valve 28. The umbrella valve 28 has an umbrella portion 31 which sealingly covers an air vent 32. The umbrella valve 28 is attached to the bottle 16 using a
When the bottle 16 is in an inverted orientation {FIG. 1 a), the internal static pressure acting against the "beak" end 12b and I3b of the duckbill valves 12 and 13, respectively, will seal the valves 12 and I3 tightly. Therefore, the valves I2 and 13 prevent fluid from prematurely flowing out of the inverted bottle I6 until the probe 23 of the receiver attachment 22 in inserted within the transfer duckbill valve 12 Upon insertion of the receiver attachment's probe 23 into the transfer duckbill valve 12, the fluid is transferred by gravity through the probe tip 23 as it deforms and opens the transfer duckbill valve 12. As a result, a vacutun (sub-atmospheric) pressure is created within the bottle 16.

Preferably, the sealing pressure of the venting duckbill valve 13 is less than the sealing pressuxe of the transfer duckbill valve 12. As a result, the vacuum (sub-atmospheric) pressure created within the bottle 16 will cause the venting duckbill valve 13 to open and not the transfer duckbill valve 12 beyond the opening created by the displacement of the valve 12 due to the probe 23.
The air vent groove 24 in the receiver attachment 22 ensures that air can reach the venting duckbill valve 13 and be drawn into the bottle 16 when sufficient sub-atmospheric pressure is generated by the transfer of the fluid from the bottle 16. As the probe tip 23 is pushed through the transfer duckbill valve 12 (F'IG. 2), the probe 23 seals along the inside wall of the duckbill valve I2. In the fully seated position (FIG. 2), the probe 23 extends through the open end 12a of the duckbill valve 12 and provides a fluid path to the tube 25.
Referring to FIGS. 3a-3c, the first alternate vent and fluid transfer fitment preferably comprises the transfer fitment 11 having a transfer check valve 27 (FIGS. 3a 3o and 3b) and a venting check valve 28. The alternate transfer check valve 27 is preferably a septum valve and the alternate venting check valve 28 is preferably an umbrella valve, both of which have an inherent sealing pressure and which are oriented in the same direction. As in the preferred embodiment, the alternate venting check valve 2$ may be located elsewhere on the bottle 16 and/or in a different orientation without deviating from the intent of the invention. The septum valve 27 is attached to the container 16 using a fitment 30.

In this way, the probe 23 is inserted through a slit 29 in the umbrella valve 28. The umbrella valve 28 has an umbrella portion 31 which sealingly covers an air vent 32. The umbrella valve 28 is attached to the bottle 16 using a
5 fitment 33. The septum valve 27 seals the opening I7 of the bottle 16 when the bottle 16 is inverted. The slit 29 allows the probe 23 to be inserted within the septum valve 27 for the transfer of the contents within the bottle I6. When the pressure builds sufficiently within the bottle i 6, the inherent sealing pressure of the umbrella valve 28, specifically the umbrella portion 31, will release arid air will be drawn within the bottle I6 until the pressure differential is equalized.
