Abstract

A storage bag includes first and second sidewalls that are directly connected, and 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.

First claim

We claim:

1. A storage bag comprising:
a first sidewall having a top edge and a bottom edge, and including a plurality of shift regions about which the bag is capable of shifting, at least one of the plurality of shift regions comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall starting from near a corner of the bottom edge of the first sidewall, wherein the at least one of the plurality of shift regions of the first sidewall comprising a score line extends across and intersects with another of the plurality of shift regions of the first sidewall comprising a score line, to facilitate the shifting of the bag; and
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 edge and a bottom edge, and including a plurality of shift regions about which the bag is capable of shifting, at least one of the plurality of shift regions comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall starting from near a corner of the bottom edge of the second sidewall, wherein the at least one of the plurality of shift regions of the second sidewall comprising a score line extends across and intersects with another of the plurality of shift regions of the second sidewall comprising a score line, to facilitate the shifting of the bag,
wherein the bag shifts 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.

2. A storage bag according to claim 1 , wherein the plurality of shift regions of the first sidewall includes at least three shift regions, with one of the shift regions extending across two other shift regions.

3. A storage bag according to claim 2 , wherein the plurality of shift regions of the second sidewall includes at least three shift regions, with one of the shift regions extending across two other shift regions.

4. A storage bag according to claim 1 , wherein the plurality of shift regions of the first sidewall includes at least three shift regions, with one of the shift regions extending across three other shift regions, and
wherein the plurality of shift regions of the second sidewall includes at least three shift regions, with one of the shift regions extending across three other shift regions.

5. A storage bag according to claim 1 , wherein the plurality of shift regions of the first sidewall includes at least four shift regions, with two of the shift regions extending across two other shift regions, and
wherein the plurality of shift regions of the second sidewall includes at least four shift regions, with two of the shift regions extending across two other shift regions.

6. A storage bag according to claim 1 , wherein the shift regions are one of changes in elevation and changes in thickness in portions of the first and second sidewalls of the bag.

7. A storage bag comprising:
a first sidewall having a top edge and a bottom edge, and including (i) a first plurality of shift regions about which the bag is capable of shifting, at least one of the first plurality of shift regions comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall starting from near the bottom edge of the first sidewall, and (ii) a second plurality of shift regions about which the bag is capable of shifting, each of the second plurality of shift regions having a beaded shape and comprising material added to the first sidewall, and each of the second plurality of shift regions extending along the first sidewall starting from near a first side of the first sidewall to near a second side of the first sidewall; and
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 edge and a bottom edge, and including (i) a first plurality of shift regions about which the bag is capable of shifting, at least one of the first plurality of shift regions comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall starting from near the bottom edge of the second sidewall, and (ii) a second plurality of shift regions about which the bag is capable of shifting, each of the second plurality of shift regions having a beaded shape and comprising material added to the second sidewall, and each of the second plurality of shift regions extending along the second sidewall starting from near a first side of the second sidewall to near a second side of the second sidewall,
wherein the bag shifts about the first plurality of shift regions and the second plurality of shift regions of the first and second sidewalls such that the bag can be shifted 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.

8. The storage bag according to claim 7 , wherein the second plurality of shift regions of the first sidewall are offset from the second plurality of shift regions of the second sidewall so as to not be positioned directly adjacent to each other when the bag is in the flat configuration.

9. The storage bag according to claim 7 , wherein the second plurality of shift regions of the first sidewall is about two to about twenty times thicker than the rest of the first sidewall, and
wherein the second plurality of shift regions of the second sidewall is two to about twenty times thicker than the rest of the second sidewall.

10. The storage bag according to claim 7 , wherein at least one of the first plurality of shift regions and the second plurality of shift regions of the first sidewall and at least one of the first plurality of shift regions and the second plurality of shift regions of the second sidewall form edges of the base of the bag when the bag is in the stand-up configuration.

11. A storage bag comprising:
a first sidewall having a top edge and a bottom edge, and including a plurality of shift regions about which the bag is capable of shifting, at least one of the plurality of shift regions comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall starting from near the bottom edge of the first sidewall, wherein the at least one of the plurality of shift regions of the first sidewall comprising a score line extends across and intersects with another of the plurality of shift regions of the first sidewall comprising a score line, to facilitate the shifting of the bag;
a first closure structure extending from a first side of the first sidewall to a second side of the first sidewall;
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 edge and a bottom edge, and including a plurality of shift regions about which the bag is capable of shifting, at least one of the plurality of shift regions comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall starting from near the bottom edge of the second sidewall, wherein the at least one of the plurality of shift regions of the second sidewall comprising a score
