Integrated vent and fluid transfer fitment
First Claim
1. A vent and fluid transfer assembly for transferring a fluid from an inverted fluid-filled bottle comprising:
- a fluid filled bottle having an opening;
a fitment removably attached to said opening of said bottle, said fitment having a vent opening and a fluid transfer opening;
a venting check valve connected to said fitment, said venting check valve having an inherent sealing pressure wherein said venting check valve is in fluid communication with said vent opening;
a receiver attachment, said receiver attachment having a substantially disk shape having a top surface and a bottom surface;
a tubular member connected to said receiver attachment, said tubular member having an upper portion with an upper opening and a lower portion with a lower opening, said upper opening being located substantially above said top surface of said receiver attachment, said lower opening being located substantially below said bottom surface of said receiver attachment wherein said upper opening is in fluid communication with said lower opening and wherein said lower opening of said tubular member is in fluid communication with a tube such that when said bottle is inverted and when said upper opening of said tubular member extends beyond said fluid transfer opening, said fluid flows by gravity from said upper opening to said lower opening within said tubular member and said fluid flows by gravity from said lower opening to said tube.

Abstract
A vent and fluid transfer fitment for sealing and transferring a fluid from an inverted fluid-filled container without premature leakage to a receiver attachment, has a transfer check valve and a venting check valve which are preferably duckbill 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 differential created as the fluid is displaced.

10. A method of transferring a fluid from a fluid container, said method comprising the steps of:
-
providing a container filled with a fluid, said container having an opening;
attaching a fluid transfer device to said opening of said container, said fluid transfer device comprising;
a fitment removably attachable to said opening of said bottle, said fitment having a vent opening and a fluid transfer opening;
a venting check valve connected to said fitment, said venting check valve having an inherent sealing pressure wherein said venting check valve is in fluid communication with said vent opening;
a receiver attachment, said receiver attachment having a substantially disk shape having a top surface and a bottom surface;
a tubular member connected to said receiver attachment, said tubular member having an upper portion with an upper opening and a lower portion with a lower opening, said upper opening being located substantially above said top surface of said receiver attachment, said lower opening being located substantially below said bottom surface of said receiver attachment wherein said upper opening is in fluid communication with said lower opening and wherein said lower opening of said tubular member is in fluid communication with a tube such that when said container is inverted and when said upper opening of said tubular member extends beyond said fluid transfer opening, said fluid flows by gravity from said upper opening to said lower opening within said tubular member and said fluid flows by gravity from said lower opening to said tube inverting said container; and
pushing said receiver attachment and said tubular member such that said upper opening of said tubular member extends beyond said fluid transfer opening and said fluid flows by gravity from said upper opening to said lower opening within said tubular member and said fluid flows by gravity from said lower opening to said tube. - View Dependent Claims (11, 12, 13, 14, 15)
