Description

[0001] DESCRIPTION [0002] Detachable inner bag in a dual bag [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag which can be separated and combined, and more particularly to a detachable inner bag of a double bag structure including an inner bag and an outer bag.

Currently, the market offers bags of various uses and designs of various materials. In general, bags differ in design and materials depending on the application, and each bag varies in size and design depending on the type and type of object stored so that it can be efficiently used for one purpose.

The bag can be divided into a shoulder bag, a clutch, a backpack, a briefcase, a carrier, etc., depending on the shape and method of use. In other words, the use of the bag has been determined, and the utilization rate of the bag has been substantially lowered, and it has been necessary to provide different kinds of bags for each use.

Due to the low utilization rate of the bag, the user's cost burden due to the purchase of the bag suitable for each application is increased for various purposes, and a space for storing such a plurality of bags must be provided. In addition, And it is practically difficult to change it according to the convenience of the user.

In order to overcome such limitations by increasing the utilization of conventional conventional bags, Korean Utility Model No. 0465652 provides a multipurpose bag capable of variously changing the external appearance of the bag in accordance with the use purpose or function of the bag. It is possible to change the shape of the bag by changing the shape of the bag from the crepe shape to the principle of different folding style. In actuality, however, the more the bag of the crepe bag is folded, There is still a limit to the utilization because the storage space that can be stored is reduced.

In addition, there is a problem that as the connecting means is easily operated, the supporting force of the lower portion of the receiving space is reduced in the connecting means provided to easily change the outer shape. For example, when the heavy items are put into the storage space, the lower floor of the storage space functions as an important supporting function. At this time, when the connection means can not sufficiently support the shape of the lower floor, There is a high probability that the articles contained in the space are poured through the lower part by gravity. Therefore, a bag having such a structure is limited in the articles that can be stored.

Japanese Patent Application Laid-Open No. 2002-325615 provides a bag comprising a plurality of storage spaces which can be separated and combined to enhance utilization of the bag. A plurality of bags having individual storage spaces are attached to each other, thereby forming a single bag, and the overall size and the number of storage spaces can be adjusted. In addition, it is possible to use a bag, a backpack, a shoulder bag or the like by attaching a bag strap or a handle to any one of the storage spaces.

Although the number of the storage spaces can be adjusted in this manner, the utilization efficiency is higher than that of the conventional bag. However, when the storage spaces are attached to each other by the attachment means such as a zipper, such attachment means are inevitably visible. And each storage space is independent, so that even if a plurality of storage spaces are attached together, it is not extended to one space.

The utilization of the conventional bag is very limited, and there is a problem that the bags provided for overcoming this are not balanced between the design aspect and practicality. In addition, it is still difficult to find a bag that can be easily changed for the sake of user's convenience in design, and can have various uses.
