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.

First claim

We claim:

1. A storage bag comprising:
(A) a first sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the bottom portion being adjacent to the bottom edge of the first sidewall, and the bottom portion including at least a first shift region and at least a second shift region about which the bag is capable of shifting, each of the shift regions comprising a score line formed into the first sidewall, each of the score lines extending a distance along the first sidewall starting from near a corner of the bottom edge of the first sidewall; and
(B) a second sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the second sidewall being directly connected to the first sidewall along the bottom edge of the first sidewall and the bottom edge of the second sidewall, the bottom portion being adjacent to the bottom edge of the second sidewall, and the bottom portion including at least a first shift region and at least a second shift region about which the bag is capable of shifting, each of the shift regions comprising a score line formed into the second sidewall, each of the score lines extending a distance along the second sidewall starting from near a corner of the bottom edge of the second sidewall,
wherein the bag shifts between (a) a flat configuration with the first and second sidewalls positioned adjacent to each other, and (b) 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 that is (i) formed by the bottom portion of the first sidewall and the bottom portion of the second sidewall, and (ii) outlined by each of the shift regions of the first sidewall and each of the shift regions of the second sidewall, and
wherein (a) an angle α is defined between (i) the first shift region of the first sidewall and an adjacent edge of the bag, and (ii) the first shift region of the second sidewall and an adjacent edge of the bag, and (b) an angle β is defined between (i) the second shift region of the first sidewall and the bottom edge of the bag, and (ii) the second shift region of the second sidewall and the bottom edge of the bag, such that (i) each angle α relates to a respective angle β to facilitate the shifting of the bag between the flat configuration and the stand-up configuration, and (ii) each angle α differs from each angle β.

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

3. A storage bag according to claim 1 , wherein (i) the at least a first shift region of the first sidewall includes shift regions that extend from near a first corner of the bottom edge of the first sidewall, and (ii) the at least a second shift region of the first sidewall includes shift regions that extend from near a second corner of the bottom edge of the first sidewall, and
wherein (i) the at least a first shift region of the second sidewall includes shift regions that extend from near a first corner of the bottom edge of the second sidewall, and (ii) the at least a second shift region of the second sidewall includes shift regions that extend from near a second corner of the bottom edge of the second sidewall.

4. The storage bag according to claim 1 , wherein the first sidewall further includes an interlocking closure structure and the second sidewall further includes an interlocking closure structure, wherein the interlocking closure structure of the first sidewall is configured to interlock with the interlocking closure structure of the second sidewall to seal the opening of the bag.

5. A storage bag comprising:
(A) a first sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the bottom portion being adjacent to the bottom edge of the first sidewall, and the bottom portion including (i) a first shift region about which the bag is capable of shifting, the first shift region comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall starting from a first corner of the bottom edge of the first sidewall, (ii) a second shift region about which the bag is capable of shifting, the second shift region comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall starting from the first corner of the bottom edge of the first sidewall, (iii) a third shift region about which the bag is capable of shifting, the third shift region comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall starting from a second corner of the bottom edge of the first sidewall, and (iv) a fourth shift region about which the bag is capable of shifting, the fourth shift region comprising a score line formed into the first sidewall, the score line extending a distance along the first sidewall starting from the second corner of the bottom edge of the first sidewall; and
(B) a second sidewall having (a) a top edge, (b) a bottom edge, and (c) a bottom portion, the second sidewall being directly connected to the first sidewall along the bottom edge of the first sidewall and the bottom edge of the second sidewall, the bottom portion being adjacent to the bottom edge of the second sidewall, and the bottom portion including (i) a first shift region about which the bag is capable of shifting, the first shift region comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall starting from a first corner of the bottom edge of the second sidewall, (ii) a second shift region about which the bag is capable of shifting, the second shift region comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall starting from the first corner of the bottom edge of the second sidewall, (iii) a third shift region about which the bag is capable of shifting, the third shift region comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall starting from a second corner of the bottom edge of the second sidewall, and (iv) a fourth shift region about which the bag is capable of shifting, the fourth shift region comprising a score line formed into the second sidewall, the score line extending a distance along the second sidewall starting from the second corner of the bottom edge of the second sidewall,
wherein the bag shifts between (a) a flat configuration with the first and second sidewalls positioned adjacent to each other, and (b) a stand-up configuration with the first and second sidewalls separated from each other, such that in the stand-up configuration, the bag has substantially flat base that is (i) formed by the bottom portion of the first sidewall and the bottom portion of the second sidewall, and (ii) outlined by the first, second, third, and fourth shift regions of the first sidewall and the first, second, third, and fourth shift regions of the second sidewall, and
wherein (a) an angle α is defined between (i) the first shift region of the first sidewall and an adjacent edge of the bag, (ii) the third shift region of the first sidewall and an adjacent edge of the bag, (iii) the first shift region of the second sidewall and an adjacent edge of the bag, and (iv) the third shift region of the second sidewall and an adjacent edge of the bag, and (b) an angle β is defined between (i) the second shift region of the first sidewall and the bottom edge of the bag, (ii) the fourth shift region of the first sidewall and the bottom edge of the bag, (iii) the second shift reg
