Abstract

A container blank having an article handling feature for handling the container blank as well as the flexible packages made therefrom during manufacture, and method of making flexible packages using such a feature are described herein. Also described herein is an array of flexible packages containing a common article handling feature provided by such a method.

First claim

What is claimed is:

1. A flexible container blank comprising:
a flexible material structure having a first side and an opposing a second side joined to said first side by a second seal comprising a first portion and a second portion spaced apart to define the size and configuration of the product volume, wherein said first and second sides each comprise two layers of flexible material, wherein said two layers comprise an inner layer and an outer layer, wherein the inner layer of each of the first and second sides of the flexible material structure define said product volume between said first side and said second side of said flexible material structure, and said product volume is configured for holding a fluent product, at least one inflatable structural support volume, wherein said structural support volume comprises a portion of said flexible material structure, and said structural support volume is located adjacent to said product volume, and a dispensing valve in fluid communication with said product volume; and
an article handling feature joined to said flexible material structure and comprising the first portion and second portion, wherein said article handling feature comprises one or more portions that are configured to be held by equipment used to make said container blank into a stand up flexible container and removed proximate to but offset outwardly from the first portion and second portion prior to sale of the container blank, wherein the article handling feature is configured to be universally adaptable to allow the handling of the container blanks having different features.

2. The flexible container blank of claim 1 wherein the article handling feature is integral with said flexible material structure.

3. The flexible container blank of claim 1 wherein said flexible container blank has a width, and said flexible container blank is approximately planar, and said article handling feature has a thickness that is measured perpendicular to the first and second sides of the flexible container blank, wherein the thickness of the article handling feature of the flexible container blank is substantially uniform along the width of the flexible container blank.

4. The flexible container blank of claim 1 , wherein said dispensing valve comprises a portion of said flexible material structure.

5. The flexible container blank of claim 1 wherein said different features of said container blanks are selected from the group consisting of: product volume, container shape; container size; and container appearance.

6. The flexible container blank of claim 1 having a top and a bottom, wherein the article handling feature aligns with a consumer functional element of the container so that the consumer functional element is located between the article handling feature and the bottom of the flexible container blank.

7. The flexible container blank of claim 6 wherein the consumer functional element is a dispensing valve.
