Bag with an elastic exterior pocket

Abstract

A carrying bag comprises an exterior pocket which includes a back wall, a front wall, an elastic side wall and a zipper assembly. At least the lower half portion of the peripheral of the back wall is seamed with the back edge of the elastic side wall. At least the lower half portion of the peripheral of the front wall is seamed with the front edge of the elastic side wall. The zipper assembly encircles the back wall and the front wall. When the zipper assembly is completely unlocked, the thickness of the exterior pocket is resiliently expandable to accommodate articles of various thicknesses, including an ordinary drink bottle.

AI Technical Summary

Benefits of technology

[0015]The advantage of this invention is that the exterior pocket of the bag provided herewith protrudes from the surface of the bag's main body only to a minimum degree when the exterior pocket is empty or is loaded only with thin and flat articles such as a mobile phone, a booklet, a Personal Digital Assistant device or a pocket sized digital camera. In addition, the front wall of the exterior pocket can be of a flat shape and with a simple contour. These characteristics are beneficial for maintaining a simple, tidy and elegant overall appearance of the bag. And when there is a need to carry an article with a greater thickness such as a drink bottle, the exterior pocket can be resiliently expanded outwards to fit the thickness of that article.

Problems solved by technology

It is difficult to design an exterior pocket of a carrying bag that not only looks tidy and neat but also can carry thicker articles such as a cylindrical bottle.

The outer wall of an exterior pocket of this type has many corrugations which may be harmful to the overall aesthetics of the bag, especially for one of a plain and tidy fashion.
