Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a case for storing and carrying articles.

(Prior Art) Conventionally, as this type of article storage case, backpack bags made of natural leather or artificial leather, such as so-called school bags, are known.

Since the bag has excellent shape retention and is durable, it is used to store books and the like when commuting to school.

However, since the bag is made of relatively hard leather, it is not only difficult to mold and cut at the manufacturing stage, but also has many seams, making it time-consuming to sew. Furthermore, the bag itself is heavy and becomes difficult to carry, especially when it contains heavy items such as books. Furthermore, although the bag has a high shape retention property, it lacks flexibility, which causes an inconvenient feeling when it comes into contact with the body when carried.

In addition, it is conceivable to manufacture this type of backpack from hard synthetic resin that is easy to mold. Stored items may be damaged. Furthermore, the bag made of hard synthetic resin lacks flexibility, similar to the leather bag, and does not solve the problem of feeling uncomfortable when it comes into contact with the body when carried.

On the other hand, for the above-mentioned backpacks, there are known article storage cases such as so-called nap bags, which are a type of backpack. The nutmeg is
It is made of cotton or chemical fiber woven fabric sewn into a bag shape, and the manufacturing process is relatively easy.

Furthermore, the nappies are originally used for day trips, but in recent years they have been widely used for any purpose due to their ease of use.

However, while these nappies are lightweight because they are made of woven fabric, they are hardly made of shape-retaining material, and when heavy items such as books are stored, the outer shape deforms significantly and becomes difficult to carry. . Furthermore, when the napkin sack is subjected to an external impact, the external force is not absorbed and has an inconvenient effect on the items stored inside.

(Problems to be solved by the invention) In order to solve these inconveniences, the present invention provides an easy-to-manufacture article storage case that is lightweight and does not damage stored items without compromising its excellent durability and shape retention. The purpose is to provide.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a back surface formed into a roughly bowl shape from a soft synthetic resin closed-cell foam covered with a woven fabric, and a roughly lower half of the back surface. and a front portion of the closed-cell foam material formed into a roughly bowl shape corresponding to the above, butted against each other at their respective edges, and continuous from one end of the abutted portion through the bottom to the other end. A second reinforcing member is provided along the edge of approximately the upper half of the back surface portion, and a first reinforcing member is provided along the edges of the upper half of the back portion, and a storage portion for storing the article is formed into a bag shape by fixing both edges to each other. The first
A lid part that can be freely opened and closed is provided at both ends of the reinforcing member and closes the opening of the storage part, and a protective member made of hard synthetic resin having a shape corresponding to the bottom part of the storage part is attached and fixed to the bottom part. It is characterized by what it did.

(Function) Examples of the soft synthetic resin include polyurethane and polyvinyl chloride. These soft synthetic resin closed cell foam materials are lightweight and highly elastic, and can be molded into molds as easily moldable materials. The surface of the soft synthetic resin is coated with a woven fabric to prevent it from being scratched or torn.

The article storage case of the present invention is made of the closed-cell foam material of the soft synthetic resin, and when manufacturing the case, the back section, the front section, and the lid section are individually molded in advance. Further, it is possible to manufacture the above-mentioned parts simply by fixing or connecting them to each other at their respective predetermined positions.

Furthermore, a first reinforcing member is provided at the abutting portion of the edges of the back surface portion and the front surface portion, and a first reinforcing member is provided continuously at both ends of the first reinforcing member along the edge edge of substantially the upper half of the back surface portion. Then, a second reinforcing member is provided to form a picture frame-like frame structure. This reinforces the soft synthetic resin and prevents deformation due to stretching of the soft synthetic resin when an article is stored in the storage section.

Further, a hard synthetic resin such as polypropylene having a shape corresponding to the bottom part is attached and fixed to the bottom part of the storage part, so that the storage part is deformed by external force and deformed by the weight of articles stored inside. ,
The bottom part is grounded to prevent damage to the bottom part when placed.
