Abstract

The present disclosure provides a flexible container. In an embodiment, the flexible container includes (A) a front panel, a rear panel, a first gusseted side panel, and a second gusseted side panel. The gusseted side panels adjoin the front panel and the rear panel along peripheral seals to form a chamber. (B) Each peripheral seal has (i) a body seal inner edge (BSIE) with a bottom end and an opposing top end, (ii) a bottom tapered seal inner edge (b-TSIE) extending from the BSIE bottom end, and (iii) a top tapered seal inner edge (t-TSIE) extending from the BSIE top end. (C) The t-TSIE has a length that is at least 1.1 times greater than the length of the BSIE (in mm).

First claim

The invention claimed is:

1. A flexible container comprising:
(A) a front panel, a rear panel, a first gusseted side panel, and a second gusseted side panel, the gusseted side panels adjoining the front panel and the rear panel along peripheral seals to form a chamber;
(B) each peripheral seal having
(i) a body seal inner edge (BSIE) with a bottom end and an opposing top end,
(ii) a bottom tapered seal inner edge (b-TSIE) extending from the BSIE bottom end;
(iii) a top tapered seal inner edge (t-TSIE) extending from the BSIE top end to a neckpoint; and

(C) the t-TSIE has a length that is at least two times greater than a length of the BSIE (in mm);
wherein each BSIE top end has a top point; and
a plane containing all four BSIE top points defines a lower container volume, the lower container volume is at least 51% of a total volume of the flexible container.

2. The flexible container of claim 1 wherein the length of the t-TSIE is from to 10 times greater than the length of the BSIE.

3. The flexible container of claim 2 wherein the flexible container comprises four BSIEs and each BSIE has a respective t-TSIE extending from the BSIE top end.

4. The flexible container of claim 1 comprising a handle.

5. The flexible container of claim 1 comprising a top handle and a bottom handle.

6. The flexible container of claim 5 wherein the top handle is a stand-up top handle.

7. The flexible container of claim 1 wherein each t-TSIE is a top arcuate tapered seal inner edge (t-ATSIE) having a radius of curvature, Rc, from 1.0 mm to 300 mm.

8. The flexible container of claim 1 having an aspect ratio from 2.0:1 to 3.0:1.

9. A flexible container comprising:
(A) a front panel, a rear panel, a first gusseted side panel, and a second gusseted side panel, the gusseted side panels adjoining the front panel and the rear panel along peripheral seals to form a chamber, a portion of each panel terminates at a neck;
(B) each peripheral seal having
(i) a body seal inner edge (BSIE) with a bottom end and an opposing top end,
(ii) a bottom tapered seal inner edge (b-TSIE) extending from the BSIE bottom end;
(iii) a top tapered seal inner edge (t-TSIE) extending from the BSIE top end to the neck; and

(C) the t-TSIE has a length (in mm) that is from two to 10 times greater than a length of the BSIE.

10. The flexible container of claim 9 wherein each BSIE top end has a top point; and
a plane containing all four BSIE top points defines a lower container volume, the lower container volume is at least 51% of the total volume of the flexible container.
