Description

  The present invention relates to an improvement of a bag.

In general, natural leather, synthetic leather, or cloth is widely used as a material for a bag skin material.
Among these, for example, when leather is used as a skin material, the leather itself has a predetermined weight, and thus the bag as a whole becomes heavy.

In addition, although it is possible to color leather, it is originally dyed in the process of leather making and given appropriate color, and it is impossible to color with free color from the viewpoint of improving appearance quality Met.
Furthermore, in the case of a bag made of synthetic leather as a skin material, there is a degree of freedom in coloring and pattern design compared to leather, but the synthetic resin deteriorates due to hydrolysis. There was a problem that it could not withstand long-term use.

On the other hand, when a bag is formed using a cloth material as a skin material, the weight becomes light and free pattern expression and coloring can be achieved by dip dyeing or printing, etc., and there is no possibility of hydrolysis and long-term use. Can withstand
However, the fabric itself has low rigidity, and even when the fabric is waterproofed, the waterproof performance is not high and there is a problem in terms of weather resistance.

From such a viewpoint, a waterproof bag is formed by joining a waterproof sheet by heat fusion to form a waterproof inner bag, forming a seam allowance on the outside of the heat fusion line, and attaching an outer fabric to the seam allowance to form a bag body. (See Patent Document 1).
However, such a conventional waterproof bag has a problem that the waterproof performance is improved, but the number of steps is increased and the manufacturing cost is increased.

The present invention has been made in view of the conventional problems as described above, and the problem is that there is a degree of freedom in pattern formation and coloring, and it is easy to use without being heavy and reducing rigidity while reducing the manufacturing cost. It is in providing the bag which has.

  In order to solve the above problems, the bag according to claim 1 includes a front fabric material and a hardly water-permeable backing material joined to the front fabric material, and the hardly-permeable backing material is provided on the back surface of the front fabric. It is characterized by being bonded via a heat bonding film.

The bag according to claim 2 is characterized in that the material of the front fabric is cotton.
In the bag according to claim 3, the hardly water-permeable backing material is made of a synthetic resin.

The bag according to claim 4 is characterized in that the synthetic resin contains any one material of nylon, polyurethane or polyester.
The bag according to claim 5 is characterized in that the hardly water-permeable backing material contains rubber.

The bag according to claim 6 is characterized in that the rubber is SBR rubber.

The bag according to claim 1 is provided with a front fabric material and a non-water-permeable backing material joined to the front fabric material, and the non-permeable material is a back surface of the front fabric. Is bonded to the surface fabric material side or the hardly water-permeable backing material side by an appropriate means so that it is sandwiched between the hardly water-permeable backing material and the surface fabric material. The heat-adhesive film is melted, and the above-mentioned hardly water-permeable backing material and the face cloth material can be easily and quickly bonded.
Since the bag according to the first aspect of the present invention is provided with the hardly water-permeable backing material, it is difficult to pass rainwater or the like dripped onto the surface fabric material when used, and water does not penetrate into the stored items. A bag having poor water permeability can be easily produced while reducing production costs.
Further, since the hardly water permeable backing material is disposed, the hardly water permeable backing material functions as a core material, and a bag having high rigidity can be provided as compared with the case of using only the front material.

In the bag according to the invention described in claim 2, since the material of the table cloth is cotton, the weight of the cloth itself is smaller than that of the leather cloth. An easy bag can be formed. Also, unlike leather fabric, various colors and patterns can be expressed on the fabric itself.
Further, when the design is printed on the fabric itself, unlike the leather fabric, since various colors and patterns can be expressed on the fabric itself, various designs can be freely expressed by combinations thereof.

  In the bag according to the inventions according to claims 3 and 4, since the hardly water-permeable lining material is made of a synthetic resin such as nylon, polyurethane or polyester, it is suitable for a skin material as compared with the case of only cotton fabric. Thus, a bag having the same rigidity as the case of using a leather fabric can be formed so as to be able to stand on its own when it is placed.

In the bag according to the invention described in claim 5, since the hardly water-permeable backing material contains rubber, it is possible to further improve the waterproofness inside the storage portion of the bag. Moreover, since the elasticity of the said hardly water-permeable backing material increases and it is excellent also in bending strength, a more easy-to-use bag can be provided.

  In the bag according to claim 8, since the rubber is SBR rubber, it is excellent in heat resistance, wear resistance, aging resistance, mechanical strength, etc., quality is stable and workability is good. Therefore, it is advantageous for forming the hardly water-permeable backing material.
