Abstract

A flexible container is provided. The flexible container includes four panels. The four panels form (i) a body portion; (ii) a neck portion, and a flare portion that extends from the neck portion; (iii) a tapered transition portion between the body portion and the neck portion; and (iv) the neck portion has a reduced width. The flare portion has an expanded end. The width of the flare portion gradually increases from the neck portion to the expanded end.

First claim

The invention claimed is:

1. A flexible container comprising:
four panels, all four panels forming
(i) a body portion;
(ii) a neck portion, and an open flare portion that extends from the neck portion;
(iii) a tapered transition portion between the body portion and the neck portion;
(iv) the neck portion having a reduced width, the open flare portion having an expanded end;
(v) a top handle extending over the open flare portion, the top handle comprising a horizontal upper portion with two spaced apart legs extending therefrom;

the open flare portion defining a frustoconical-shaped inner volume whereby the width of the open flare portion gradually increases from the neck portion to the expanded end, and wherein the open flare portion is unsealed;
each panel includes a bottom face comprising two opposing peripheral tapered seals, each peripheral tapered seal extending from a respective peripheral seal, each peripheral tapered seal comprising an inner edge, the peripheral tapered seals converging at a bottom seal area;
the front panel bottom face comprises a first line defined by the inner edge of the first peripheral tapered seal and a second line defined by the inner edge of the second peripheral tapered seal inner edge, the first line intersecting the second line at an apex point in the bottom seal area;
the front panel bottom face has a bottom distalmost inner seal point on the inner edge; and
the apex point is separated from the bottom distalmost inner seal point by a distance from greater than 0 mm to less than 8.0 mm.

2. The flexible container of claim 1 wherein the expanded end has a width that is greater than the width of the neck portion.

3. The flexible container of claim 1 wherein the expanded end has a width that is from 1.1 times to 8.0 times greater than the width of the neck portion.

4. The flexible container of claim 1 wherein the panels are formed from a multilayer film having a seal layer comprising a polymer.

5. The flexible container of claim 1 , wherein the flexible container comprises the top handle and a bottom handle.

6. The flexible container of claim 5 , wherein the bottom handle is formed from all four bottom faces sealed together.

7. The flexible container of claim 1 , wherein the neck portion is centered between the legs of the top handle.

8. The flexible container of claim 1 comprising a single top handle formed from all four panels sealed together.

9. The flexible container of claim 1 comprising
an overseal in the bottom seal area and only within the peripheral tapered seals, wherein each panel is sealed to a portion of every other panel in the overseal; and
the apex point is separate from and does not contact the overseal.

10. The flexible container of claim 9 , wherein a distance between the apex point and a top edge of the overseal is from greater than 0 mm to 15.0 mm.

11. The flexible container of claim 9 , wherein the bottom distalmost inner seal point is separated from and does not contact the overseal.

12. The flexible container of claim 11 , wherein the apex point and the bottom distalmost inner seal point are located above the overseal.

13. The flexible container of claim 1 , wherein each panel comprises a flexible multilayer film comprising
a seal layer comprising an olefin-based polymer having a first melt temperature (Tm 1 ) that is less than 105° C.;
an outer layer comprising a polymeric material having a second melt temperature (Tm 2 );
ΔTm=Tm 2 −Tm 1 ; and
ΔTm is greater than 40° C.
