Abstract

A three-dimensional structure composed of pliable elements and having affixed seams is provided. The structure may comprise duffel bags, backpacks, shoe uppers, etc. The structure has a bottom panel with a first terminal bottom portion and a first end panel with a terminal end portion. As well, the first terminal bottom portion and the terminal end portion are affixed to each other in a flattened, two-dimensional arrangement by a variety of attachment methodologies including a thermoplastic elastomer strip. Two-dimensional construction saves time and helps to reduce manufacturing costs.

Description

technical field [0001] The present invention relates to three-dimensional structures made of flexible elements that can be assembled in two dimensions. More specifically, the present invention relates to bags having welded seams. Background technique [0002] The process of making a bag, or any three-dimensional structure made of flexible elements, is often accomplished by stitching together pieces of material. To sew multiple pieces together, the bag can be turned inside out, the seams are sewn together, and the bag is turned right side out. With or without turning inside out, the assembly of this structure requires manipulation in three dimensions. Additionally, these stitched-together seams may be prone to tearing and have limited resistance to oil, water, and other liquids or fine particles. Contents of the invention [0003] This overview is provided to introduce a selection of concepts in a simplified form that are further explained below in the detailed descripti...
