A reclosable fastener having a one-way valve interposed between first and second sets of interlocking members permits fluid flow in one direction through the fastener and blocks fluid flow in an opposite direction through the fastener.
Claims13
A reclosable fastener, comprising:
- a. a first set of interlocking members;
- b. a second set of interlocking members;
- c. a one-way valve interposed between the first set of interlocking members and the second set of interlocking members, the valve comprising a resilient flap and an opposed seat, said flap being held against the seat to provide fluid sealing in one direction and permitting fluid flow in the opposite direction when at least one of said first or second set of interlocking members is in the interlocked condition.
A reclosable fastener, comprising:
- a. a first set of interlocking members;
- b. a second set of interlocking members;
- c. a one-way valve interposed between the first set of interlocking members and the second set of interlocking members, the valve comprising a resilient flap and an opposed seat, said flap being held against the seat to provide fluid sealing in one direction and permitting fluid flow in the opposite direction when at least one of said first or second set of interlocking members is in the interlocked condition;
- the reclosable fastener further comprising a first base portion and a second base portion, wherein the first set of interlocking members comprises first and second spaced apart interlocking members extending from the first base portion, and a contact surface extending from the first base portion;
- and wherein the second set of interlocking members comprises third and fourth spaced apart interlocking members extending from the second base portion, said flap of said valve extending from the second base portion;
- wherein a first cavity is formed between the first base portion and the second base portion, and between the first and third interlocking members and the valve;
- wherein a second cavity is formed between the first base portion and the second base portion, and between the second and fourth interlocking members and the valve;
- and
- at least one first orifice formed in a first interlocking member of the first set of interlocking members, and at least one second orifice formed in a second interlocking member of the first set of interlocking members.
