Child-deterrent packaging having a barrier to protect contents from surrounding environment

A resealable assembly for joining opposing first and second sidewalls of an enclosure, the first sidewall having a slit and forming an entry section, the resealable assembly comprising:

• a first zipper portion configured to be affixed to the first sidewall;
• a second zipper portion configured to be affixed to the second sidewall, the first and second zipper portions shaped to mate and unmate with each other to enclose and provide access to, respectively, an interior cavity of the enclosure, wherein a force is required to release the first and second zipper portions, and wherein the force is greater when the force is applied to the enclosure above and between the first and second zipper portions and the entry section than when the force is applied to the enclosure on the side of the zipper portions opposite the entry section and below the zipper portions;
• and
• a peel seal one or more of:
• coupling the entry section of the first sidewall with the first zipper portion, coupling the entry section of the first sidewall with another portion of the first sidewall, or coupling the first zipper portion with the second zipper portion such that the peel seal provides greater resistance to rupture when a transverse force is applied to the enclosure above and between the first and second zipper portions and the entry section than when the force is applied to the enclosure on the side of the zipper portions opposite the entry section and below the zipper portions.

An enclosure comprising:

• first and second sidewalls coupled with each other, the first sidewall having an entry section extending away from the first sidewall to an outer edge;
• a zipper assembly coupled with the first and second sidewalls and disposed between the second sidewall and the entry section of the first sidewall, the zipper assembly configured to enclose an interior cavity between the first and second sidewalls and open to provide access to the interior volume wherein a force is required to release the first and second zipper portions, and wherein the force is greater when the force is applied to the enclosure between the first and second zipper portions and the entry section than when the force is applied to the enclosure above and on the side of the zipper portions opposite the entry section and below the zipper portions;
• and
• a peel seal one or more of:
• disposed between and coupling the entry section of the first sidewall with the zipper assembly, disposed between and coupling the entry section of the first sidewall with another portion of the first sidewall, or disposed between and coupling opposing surfaces of the zipper assembly with each other such that the peel seal provides greater resistance to rupture when a transverse force is applied to the enclosure between the first and second zipper portions and the entry section than when the force is applied to the enclosure above and on the side of the zipper portions opposite the entry section and below the zipper portions.
