Problems solved by technology

Soft bags, although they can be agreeable in appearance and light in weight, often do not afford adequate protection to the contents against external forces.
Such rigid internal frames, however, add significantly to manufacturing costs and also increase weight.
Such bags, however, tend to be less attractive in appearance or to the touch.
Additionally, hard bags often require more complex manufacturing techniques, including the use of expensive molding techniques that require complex and expensive equipment, multiple heating and cooling steps, trimming steps, and cleaning steps to produce the luggage body.
The amount of time the molding equipment is utilized to produce a piece of luggage is a significant factor in the cost of manufacturing that piece of luggage.
Thus, the manufacture of hard bags can be expensive and time consuming compared to soft bags.

Abstract

A piece of luggage including at least one section of a stiff shell material is provided. The at least one section of the stiff shell material defines a first face of the piece of luggage and has at least one corner. A portion of the at least one section has been removed to define at least one notch proximate the at least one corner. First and second edges of the at least one section adjacent the notch are folded inward relative an inner surface of the at least one section forming first and second sides. The first and second sides define second and third faces of the piece of luggage. The piece of luggage further includes at least one rigid corner piece secured to the first and second sides proximate the at least one notch.

Description

FIELD OF THE INVENTION[0001]The disclosed subject matter relates to a system for lightweight, high-strength luggage or other bags, and for a method for the manufacture thereof.BACKGROUND[0002]In the luggage or bag field, there are generally two basic types of construction: (1) soft bags, in which the outer walls are made of a flexible material such as leather, vinyl, fabric, etc., and (2) hard bags, in which the outer walls are made of a hard plastic material such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), etc. Soft bags, although they can be agreeable in appearance and light in weight, often do not afford adequate protection to the contents against external forces. For greater resistance to deformation, rigid internal frames have been provided in soft bags to maintain the shape of the bag. Such rigid internal frames, however, add significantly to manufacturing costs and also increase weight.[0003]Hard bags have the advantage of resistance to deformation by ...
