Claims13
A resealable closure comprising:
- a male profile comprising a head defined by a head sidewall;
- a female profile comprising a restraining member adapted to restrainably engage the head of the male profile defined by a restraining member sidewall;
- and
- a sealant material disposed within a channel formed in at least one of the female profile and the male profile, and spaced apart from the corresponding at least one of the head sidewall and the restraining, member sidewall, wherein the sealant material flows out of the channel upon application of a sufficient force.

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 formed within 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 with a sufficient force, the sidewall at least partially ruptures, thereby allowing the sealant material to flow out of the channel.
