Abstract
A pouch construction has a flexible stand-up pouch having first and second opposite panels and a bottom or base gusset. The flexible pouch has a seal perimeter surrounding an open interior. In a portion of the seal perimeter, there is provided a peel seal region. The flexible pouch construction has an unsealed region, along a perimeter edge, spaced from the interior of the pouch by the peel seal region. As a result, in the unsealed region, the pouch panels can be spread apart allowing a straw or similar member to be pushed between the panels, in the region of the peel seal, to open the pouch for access to a drink contained inside. Methods of constructing such arrangements, and preferred pouch blanks that can be filled to form such arrangements are described.

A pouch construction comprising:
- (a) first and second, opposed, panel sections;
- (b) a base gusset positioned between the first and second panel sections;
- (i) the first and second panel sections and base gusset each comprising flexible film material and together forming a stand-up pouch having a perimeter edge, a closed perimeter seal defining and surrounding an open, interior, volume;
- (c) an unsealed perimeter edge region between the first and second panel sections in a region adjacent to a perimeter edge of the pouch construction whereat the first and second panel sections can be partially spread apart;
- (i) the unsealed perimeter edge region defining a perimeter area of at least 20 sq. mm;
- (ii) the unsealed perimeter edge region being defined by a seal region to have a V-shaped edge with an apex region directed toward the pouch interior;
- (A) the V-shaped edge having a truncated V-shaped apex with an apex edge thereof positioned spaced no more than 6 mm from the pouch interior;
- and
- (d) a peel seal region adjacent to the unsealed perimeter edge region and defining a base portion between the unsealed perimeter edge region and the pouch construction open interior volume.
A pouch construction comprising:
- (a) first and second, opposed, panel sections;
- (b) a base gusset positioned between the first and second panel sections;
- (i) the first and second panel sections and base gusset each comprising flexible film material and together forming a stand-up pouch having a perimeter edge, a closed perimeter seal defining and surrounding an open, interior, volume;
- (ii) the first and second panel sections defining a pouch top edge opposite the base gusset;
- (c) an unsealed perimeter edge region between the first and second panel sections in a region adjacent to a perimeter edge of the pouch construction whereat the first and second panel sections can be partially spread apart;
- (i) the unsealed perimeter edge region being defined by a seal region to have a V-shaped edge with an apex region directed toward the pouch interior;
- (A) the V-shaped edge having a truncated V-shaped apex with an apex edge thereof positioned spaced no more than 6 mm from the pouch interior;
- (ii) the pouch top edge defining a side of the unsealed perimeter edge region;
- and
- (d) a peel seal region adjacent to the unsealed perimeter edge region and defining a base portion between the unsealed perimeter edge region and the pouch construction open interior volume.
A pouch construction comprising:
- (a) first and second, opposed, panel sections;
- (b) a base gusset positioned between the first and second panel sections;
- (i) the first and second panel sections and base gusset each comprising flexible film material and together forming a stand-up pouch having a perimeter edge, a closed perimeter seal defining and surrounding an open, interior, volume;
- (ii) the first and second panel sections defining a pouch top edge opposite the base gusset;
- (c) an unsealed perimeter edge region between the first and second panel sections in a region adjacent to a perimeter edge of the pouch construction whereat the first and second panel sections can be partially spread apart;
- (i) the unsealed perimeter edge region being defined by a seal region to have a V-shaped edge with an apex region directed toward the pouch interior;
- (d) an access notch defined by the first panel section and positioned in the unsealed perimeter edge region adjacent to the pouch top edge;
- (i) the notch defining a perimeter area within the range of 40 to 80 sq. mm.;
- and
- (e) a peel seal region adjacent to the unsealed perimeter edge region and defining a base portion between the unsealed perimeter edge region and the pouch construction open interior volume.
