Method of forming flexible container with gussets

Abstract

The present invention provides a method of forming a flexible container having a gusset comprising successive Z-folding and reverse Z-folding movements of a continuous film followed by continuous V-folding of the longer extension of the Z-fold , and move the sides of the web into adjacent positions.

Description

technical field [0001] The present disclosure relates generally to flexible containers, and in particular to methods of forming flexible containers with gussets. Background technique [0002] Fluid products include liquid products and / or pourable solid products. In various embodiments, a container can be used to receive, contain and dispense one or more fluid products. Also, in various embodiments, containers may be used to receive, hold and / or dispense individual articles or separately packaged portions of products. A container may contain one or more product spaces. The product space is configured to be filled with one or more fluid products. When filling the product space of the container, the container receives a fluid product. Once filled to the desired volume, the container can be configured to hold the fluent product in its product space until the fluent product is dispensed. The container holds the fluent product by providing a barrier around the fluent product....

AI Technical Summary

Problems solved by technology

Both types of manufacturing are energy-intensive processes that may require complex equipment

[0008] Second, some conventional rigid containers for fluid products may require significant amounts of material

This may require a significant amount of material, which increases the cost of the container and makes its disposal difficult

[0009] Third, some conventional rigid containers for fluid products can be difficult to decorate

The size, shape (e.g. curved surface) and / or material of some rigid containers make it difficult to print directly on their outer surface

Labeling requires additional materials and handling, and limits the size and shape of decorations

Packaging provides a large decorative area, but also requires additional materials and handling, often at significant cost

[0010] Fourth, some conventional rigid containers used for flowable products may be prone to certain types of damage

If a rigid container is pressed against a hard object, the container can become dented, which can make it look unsightly

And if the rigid container is dropped, the container may break, which can cause loss of its fluid product

[0011] Fifth, some fluid products in conventional rigid containers can be difficult to dispense

Other users may need to apply so much hand force that they cannot easily control the degree to which the container is deformed; these users may dispense more fluid product than they desire

[0012] Sixth, when using conventional rigid containers, it may be difficult for manufacturers to change such containers from one product size to another

Unfortunately, making a new size of the container can be costly, time consuming and difficult to coordinate
