[Action]

 According to the first aspect of the present invention, the synthetic resin film material on the back side is slightly thickened to improve the shape retention rigidity of the bag, so that the bag does not become deformed even when it is leaned against the display shelf and a good appearance is obtained. In addition, the contents can be prevented from being deformed or damaged.

Since it is one article, raw materials can be easily procured and processed, and it is easy to handle. Also, the work of storing the contents can be performed in a single process, and the packing work is easy and requires no labor. As a result, the total cost can be reduced. The storage space is also small, the waste does not become bulky, and the energy required for incineration is small.

According to the second aspect of the invention, by embossing the inner surface of the synthetic resin film material on the back side, it is possible to give a frictional resistance to the food and to obtain a non-slip effect. Even the movement of food can be prevented.

According to the third aspect of the present invention, by providing the gussets on the three sides of the synthetic resin film material on the front side, it is possible to store a bulky article and improve the appearance.

[0016]

[Embodiment of device]

 An embodiment of the food storage bag of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a vertical sectional view of the food storage bag 1 displayed in a leaning state, and FIG. 2 is an external perspective view thereof. In these figures, reference numeral 2 is a thin flexible skin film (a synthetic resin film material on the front side) made of, for example, a composite of a biaxially stretched film of polypropylene and an unstretched film, and 3 is the skin film 2 Made of the same material as, but slightly thicker and with moderate rigidity, a backing film (backside synthetic resin film material), 4 is food stored inside (shiitake mushroom dry matter), 5 is a display shelf, and 6 is a horizontal rail. . When the food 4 is a delicacy or a high-grade knob, it is preferable to use a saran-coated polypropylene film, nylon film or the like as the material for the skin film 2 and the back film 3.

It is appropriate that the thickness of the above-mentioned skin film 2 is 30 to 100 μm and the thickness of the back skin film 3 is about 100 to 200 μm, so that a suitable thickness can be selected depending on the kind of food to be stored. Preferably.

The food storage bag 1 is provided by heat-sealing h as the three sides of the outer skin film 2 and the back skin film 3 are joined together, and the remaining one side is sealed after the contents (food) 4 are packed. Therefore, both vacuum packing and semi-vacuum packing are possible, and it is also possible to pack without vacuuming.

Before the contents 4 are packed, it is one article, is not bulky, requires a small space for storage, is easy to handle, and can be easily set up during packing. It is not bulky and requires less energy when incinerated.

Since the filling operation of the contents 4 described above is a single article, it may be a single step of just filling the contents as it is, and it can be easily and quickly carried out without any trouble. The cost required for the work is low, and the total cost can be greatly reduced in addition to the fact that it is one item.

In the state in which the contents 4 are packed, the rigidity of the backing film 3 causes the entire food storage bag 1 to have an appropriate shape-retaining rigidity, and it deforms even when displayed in a leaning state as shown in FIG. It is possible to obtain a good appearance and prevent the contents from being deformed or damaged.

3A and 3B show different embodiments. In this case, the inner surface of the backing film 3 is embossed to prevent the contents 4 from moving. In the embossing process, it is preferable to form an emboss (protrusion or ridge) of, for example, about 0.3 mm, but the emboss may be set to an appropriate height depending on the contents, and The embossed pattern may be appropriately selected from a lattice pattern, a diamond pattern, a turtle shell pattern, and the like. By the way, it is preferable that the lattice pattern has a mesh size of about 2 mm x 2 mm.

FIGS. 4 (A) and 4 (B) show another embodiment, in which a gusset 7 is formed on three sides of the skin film 2 so that the bulky contents 4 can be stored without difficulty and a good appearance is obtained. It was made possible to obtain. In this case, it is preferable to provide a slightly larger protrusion by embossing.

[0024]

[Effect of device]

 As described above, according to the first aspect of the invention, the thickness of the synthetic resin film material on the back side is set to the extent that the shape-retaining rigidity can be appropriately obtained with the food stored inside. Since it is thicker than the material, it does not deform even if it is leaned against the display shelf, and it has a good appearance and prevents the contents from being deformed or damaged.

Since it is one article, raw materials can be easily procured and processed, and it is easy to handle. Also, the work of storing the contents can be performed in a single process, and the filling work is easy and hassle-free. As a result, the total cost can be reduced. It also requires a small storage space, does not become bulky as garbage, and requires less energy when incinerated.

According to the second aspect of the present invention, by embossing the inner surface of the synthetic resin film material on the back side made of a thick synthetic resin film material, a friction resistance is provided between the synthetic resin film material and a food product to prevent slipping. It is possible to prevent the movement of food even when leaning against it.

In the device according to the third aspect, by providing the gussets on the synthetic resin film material on the front side, it is possible to store a bulky article and improve the appearance.
