## 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).

## Claims

### Claim 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; and
C. the t-TSIE has a length that is at least 1.1 times greater than the 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 the total volume of the flexible container.

### Claim 2 (depends on 1)

The flexible container of claim 1 wherein the length of the t-TSIE is from 1.1 to 10 times greater than the length of the BSIE.

### Claim 3 (depends on 2)

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.

### Claim 4

(canceled)

### Claim 5 (depends on 1)

The flexible container of claim 1 comprising a handle.

### Claim 6 (depends on 1)

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

### Claim 7 (depends on 6)

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

### Claim 8 (depends on 1)

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.
