Washable, waterproof, sealable and reusable storage bags
Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

7. The storage bag of claim 5 , wherein the elongated member of the first half of the double-locking closure mechanism has a narrowest locking point, wherein the channel of the first half of the double-locking closure mechanism has pressure contact points, wherein the pressure contact points define a channel opening that is not greater than the narrowest locking point of the elongated member of the first half of the double-locking closure mechanism.
8. The storage bag of claim 1 , wherein the double-seal has a minimum width and wherein the gusset has a width that is approximately not less than three times the minimum width of the double-seal.
9. The storage bag of claim 1 , wherein the first portion and the second portion are made of same thermoplastic material.
10. The storage bag of claim 1 , wherein the first portion and the second portion are made of different thermoplastic materials.
11. A storage bag, comprising:
a first sidewall consisting of a first portion and a second portion, the first portion having a first half of a double-locking closure mechanism, the second portion having a flat or substantially flat surface, the first portion and the second portion affixed edge to edge to each other, forming a seam along a base of the first half of the double-locking closure mechanism;
a second sidewall consisting of a complementary first portion and a complementary second portion, the complementary first portion having a second half of the double-locking closure mechanism, the complementary second portion having a flat or substantially flat surface, the complementary first portion and the complementary second portion affixed edge to edge to each other, forming a seam along a base of the second half of the double-locking closure mechanism, wherein the first portion of the first side wall and the complementary first portion of the second side wall have different heights or widths; and
a double-seal traversing along three sides of the first sidewall and the second sidewall, leaving an opening through the double-locking closure mechanism, the double-seal comprising a gusset between the double-seal and also traversing along the three sides of the first sidewall and the second sidewall.
12. The storage bag of claim 11 , further comprising:
a first seal joining a first corner of the first sidewall, a first corner of the second sidewall, and a first end of the double-locking closure mechanism; and
a second seal joining a second corner of the first sidewall, a second corner of the second sidewall, and a second end of the double-locking closure mechanism, wherein the first seal, the second seal, and the double-locking closure mechanism have same thickness.
13. The storage bag of claim 12 , wherein at least one of the first seal or the second seal has an L-shaped profile, a box-shaped profile, a half-elliptical shaped profile, or a half-moon shaped profile.
14. The storage bag of claim 11 , wherein at least one of the first sidewall or the second sidewall is textured with a pattern.
15. The storage bag of claim 11 , wherein the first half of the double-locking closure mechanism has an elongated member extending along the base of the first half of the double-locking closure mechanism, wherein the second half of the double-locking closure mechanism has a channel extending along a base of the second half of the double-locking closure mechanism.
