Abstract
Resealable closures for use in sealing polymeric packages are provided. The resealable closures include a sealant material that restricts fluid flow into and out of the resealable closure.
Claims20
A resealable closure comprising:
- a male profile comprising a head;
- a female profile comprising a restraining member adapted to restrainably engage the head of the male profile;
- and
- a sealant material sealed within at least one of the female profile and the male profile.
1 more element
A method for forming a substantially air-tight resealable closure for use with a polymeric package, the method comprising:
- forming a male profile and a female profile of a resealable closure, the female profile being adapted to restrainably engage at least a portion of the male profile;
- creating, within at least one of the male profile and the female profile, a channel containing a sealant material;
- interconnecting the male profile and the female profile;
- and
- flowing the sealant material into a gap between the male and female profile, thereby substantially restricting gases from flowing through the gap.
2 more elements
A resealable closure comprising:
- a first complementary member;
- a second complementary member adapted to interconnect with the first complementary member;
- and
- a sealant material sealed within a channel of the first complementary member, the channel being spaced from a sidewall of the first complementary member by a distance, the distance being sufficiently small such that upon engagement of the first and second complementary members, the sidewall at least partially ruptures, thereby allowing the sealant material to flow out of the channel.
