Abstract

A storage bag includes first and second sidewalls that are directly connected without a pleat between the sidewalls at a bottom of the bag. The bag includes a plurality of shift regions at bottom portions of the sidewalls. The bag can be moved about the shift regions such that the bag is shiftable between a flat configuration with the first and second sidewalls positioned adjacent to each other and a stand-up configuration with the first and second sidewalls separated from each other. In the stand-up configuration, the bag is shifted about the shift regions such that a substantially flat base is formed for the bag. The stand-up configuration is thereby achieved without a pleat being provided between the sidewalls at a bottom of the bag. The bag further includes a cuff region that is disposed below the top of the bag for cuffing of the top of the bag.

First claim

We claim:

1. A storage bag comprising:
a first sidewall having a top portion and a bottom portion, and including (i) at least one shift region about which the bag is capable of shifting, the at least one shift region being provided in the bottom portion of the first sidewall, and the at least one shift region comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall, (ii) a first closure structure extending from a first side of the first sidewall to a second side of the first sidewall, and (iii) a cuff line disposed below the first closure structure;
a second sidewall directly connected to the first sidewall along three sides of the bag to form an interior of the bag with an opening thereto, the second sidewall having a top portion and a bottom portion, and including (i) at least one shift region about which the bag is capable of shifting, the at least one shift region being provided in the bottom portion of the second sidewall, and the at least one shift region comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall, (ii) a second closure structure extending from a first side of the second sidewall to a second side of the second sidewall, the second closure structure being configured to interlock with the first closure structure and thereby seal the opening of the bag, and (iii) a cuff line disposed below the second closure structure; and
a cuff region disposed below a top edge of the first sidewall and a top edge of the second sidewall, the cuff region extending from a point below each of the top edges of the first and second sidewalls to the cuff line of each of the first and second sidewalls, and the cuff region comprising a textured patterned band to provide a visual cue to a user as to where to fold and to cuff the bag,
wherein the bag shifts:
(a) between (i) a flat configuration with the first and second sidewalls positioned adjacent to each other, and (ii) a stand-up configuration with the first and second sidewalls separated from each other, such that, in the stand-up configuration, the bag has a substantially flat base, and
(b) about the cuff line of each of the first and second sidewalls such that the bag can be shifted to a cuffed position with the bag being folded over the cuff line of each of the first and second sidewalls and the cuff region forming the opening to the bag.

2. A storage bag according to claim 1 , wherein, on the first sidewall, the cuff region extends from the first interlocking closure structure of the first sidewall to the cuff line of the first sidewall, and
wherein, on the second sidewall, the cuff region extends from the second interlocking closure structure of the second sidewall to the cuff line of the second sidewall.

3. A storage bag according to claim 1 , wherein the first sidewall further includes a third interlocking closure structure disposed below the first interlocking closure structure, and the second sidewall further includes a fourth interlocking closure structure disposed below the second interlocking closure structure, wherein the third interlocking closure structure is configured to interlock with the fourth interlocking closure structure to seal the opening of the bag.

4. A storage bag according to claim 3 , wherein, on the first sidewall, the cuff region extends from the third interlocking closure structure of the first sidewall to the cuff line of the first sidewall, and
wherein, on the second sidewall, the cuff region extends from the fourth interlocking closure structure of the second sidewall to the cuff line of the second sidewall.

5. A storage bag according to claim 1 , wherein the cuff line of each of the first and second sidewalls comprises a straight line that extends from a first edge to a second edge of the respective sidewall.

6. A storage bag according to claim 1 , wherein the cuff line of each of the first and second sidewalls comprises a dashed line that extends from a first edge to a second edge of the respective sidewall.

7. A storage bag according to claim 1 , wherein the cuff line of each of the first and second sidewalls comprises a curved line that extends from a first edge to a second edge of the respective sidewall.

8. A storage bag according to claim 1 , wherein the patterned band is formed by embossing.

9. A storage bag according to claim 1 , wherein the bottom portion of at least one of the first sidewall and the second sidewall comprises a patterned area.

10. A storage bag according to claim 9 , wherein at least one of the patterned band and the patterned area is formed by embossing.

11. A storage bag according to claim 9 , wherein the patterned band comprises a pattern that is the same as the pattern of the patterned area.

12. A storage bag according to claim 9 , wherein the patterned band comprises a pattern that is different from the pattern of the patterned area.

13. A storage bag according to claim 1 , wherein each of the first sidewall and the second sidewall comprises a patterned area that extends from a point below each of the top edges of the first and second sidewalls to at least the bottom portion of each of the first and second sidewalls,
wherein the patterned area of each of the first and second sidewalls is included for at least one of (i) disguising the cuff line of each of the respective first and second sidewalls, (ii) disguising the at least one shift region of each of the respective first and second sidewalls, (iii) adding stiffness to each of the first and second sidewalls, and (iv) providing a visual cue to a user as to where to fold and to cuff the bag.

14. A storage bag according to claim 13 , wherein the patterned area is formed by embossing.

15. A storage bag according to claim 1 , wherein the at least one shift region of the first sidewall includes (i) shift regions that extend from near a first corner of the first sidewall and (ii) shift regions that extend from near a second corner of the first sidewall, and
wherein the at least one shift region of the second sidewall includes (i) shift regions that extend from near a first corner of the second sidewall and (ii) shift regions that extend from near a second corner of the second sidewall,
wherein, in the stand-up configuration, the bag is shifted about each of the shift regions of the first sidewall and about each of the shift regions of the second sidewall such that the substantially flat base is formed for the bag.

16. A storage bag according to claim 1 , wherein the at least one shift region of the first sidewall includes (i) a first shift region that extends from near a first corner of the first sidewall, (ii) a second shift region that extends from near the first corner of the first sidewall, (iii) a third shift region that extends from near a second corner of the first sidewall, and (iv) a fourth shift region that extends from near the second corner of the first sidewall, and
the at least one shift region of the second sidewall includes (i) a first shift region that extends from near a first corner of the second sidewall, (ii) a second shift region that extends from near the first corner of the second sidewall, (iii) a third shift region that extends from near a second corner of the second sidewall, and (iv) a fourth shift region that extends from near the second corner of the second sidewall,
wherein, in the stand-up configuration, the bag is shifted about the first, second, third, and fourth shift regions of the first sidewall and about the first, second, third, and fourth shift regions of the second sidewall suc
