Abstract

The present disclosure provides a flexible container. In an embodiment, the flexible container include (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 from a chamber. (B) Each peripheral seal has (i) an arcuate body seal inner edge (ABSIE) with opposing ends, (ii) a tapered seal inner edge (TSIE) extending from each end of the body seal. (C) The flexible container includes at least one ABSIE having a radius of curvature, Rc, from 1.0 mm to 300.0 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) an arcuate body seal inner edge (ABSIE) with opposing ends,
(ii) a tapered seal inner edge (TSIE) extending from each end of the body seal;

C. the flexible container comprises at least one ABSIE having a radius of curvature, Rc, from 1.0 mm to 300.0 mm;
D. wherein each ABSIE has a peak arc point; and
a plane through all four of the peak arc points defines a lower chamber volume that is greater than 50% of the total volume to the container.

2. The flexible container of claim 1 wherein the flexible container has an aspect ratio from 1:1 to 3:1.

3. The flexible container of claim 1 wherein the flexible container comprises four ABSIEs, each ABSIE having a Rc from 3.0 mm to 100.0 mm.

4. The flexible container of claim 3 wherein each ABSIE has an Rc from 3.0 mm to 100.0 mm and an aspect ratio from 1.2 to 3.0.

5. The flexible container of claim 4 wherein the flexible container has a volume from 0.5 L to 30.0 L.

6. The flexible container of claim 1 comprising a bottom apex and an oversea) in the apex.

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

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

9. The flexible container of claim 8 wherein the top handle is a stand-up top handle.

10. The flexible container of claim 1 wherein a top end section of each panel is sealed to a spout.

11. The flexible container of claim 10 wherein each panel extends to a bottom apex portion.

12. The flexible container of claim 1 comprising a corner arc extending between each ABSIE end an respective TSIE.

13. The flexible container of claim 12 wherein the peak arc point is not a corner arc.

14. 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) an arcuate body seal inner edge (ABSIE) with opposing ends,
(ii) a tapered seal inner edge (TSIE) extending from each end of the body seal
(iii) a corner arc extending between each ABSIE end and respective TSIE;

C. the flexible container comprises at least one ABSIE having a radius of curvature, Rc, from 1.0 mm to 300.0 mm;
D. wherein each ABSIE has a peak arc point; and
a plane through all four of the peak arc points defines a lower chamber volume that is greater than 50% of the total volume to the container.
