Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a composite container for containing a slurry such as miso, in which the mouth body is a molded product and the bag body is a plastic film.

(Conventional technology) When plastic bags are used to store muddy substances such as miso, lard, and boiled beans, the mouth of the bag is difficult to open wide, so the contents tend to stick to the inside of the bag's mouth when the bag is stored or taken out. In addition, due to the disadvantage of getting one's hands dirty when storing or taking out a bag, the inventor of the present invention published Utility Model Application No. 56-177350 (Utility Model Publication No. 61-3800), in which a flange is formed at right angles to the flange of a hard plastic bag frame. We proposed a method in which the mounting part was glued to the edge of the bag.

(Problems to be solved by the invention) According to the above, it was possible to obtain a flexible packaging container that allows the opening of the bag to be opened wide and does not stain hands, etc. However, since the bag body is made of plastic and is a flexible packaging container, the center of the bag tends to bulge out and does not retain its shape, making it inconvenient to pack a large number of items in a box. It is difficult to maintain the bag in an upright position, and therefore filling the bag with slurry and removing it from the bag is not always convenient.

The object of the present invention is to obtain a composite container that is convenient for filling a bag with slurry and removing it therefrom, and has shape-retaining properties.

(Means for Solving the Problems) In order to achieve the above objects, the present invention provides a composite container consisting of the following bag body and molded product.

In other words, a bag attachment part is provided below the rectangular mouth edge of the mouth part body made of a molded product, and the four corners are vertically sealed on this part to provide the mouth part of the bag body made of plastic film with great buckling strength. This is a composite container consisting of a bag with adhesive edges and a molded product.

(Function) The present invention is a composite container consisting of a plastic injection molded product, or a draw molded product made of aluminum or tin plate, and a bag body made of plastic film or a sheet, so that the bag retains its shape even when the contents are filled. In order to maintain the shape, the four corners are sealed, so that even when used in an upright position, it does not buckle and retains its shape well.

(Example) The drawings will be explained below.

A composite container A according to the present invention consists of a mouth body a and a bag body b, as shown in FIG.
The mouth main body a has a rectangular mouth rim and consists of a mouth rim 1 and a mounting part 2 for attaching the bag body b below, and is made of plastic injection molding, aluminum or tin. It is a draw-molded product. Bag body b is a multilayer plastic film or sheet (hereinafter referred to as plastic film) having barrier properties, and has a back seal 3 forming bag body b.
In addition, the four corners are vertically corner-sealed 4 so as to match the square corners of the bag attachment part 2 of the mouth body a; Since it is welded to the mounting portion 2 of the holder, only this welded portion 4' is not corner sealed 4. The bottom of such a bag b is of course sealed, and at the unsealed corner 4' of the mouth, it is fitted into the attachment part 2 below the mouth main body a and heat welded. Install it.

To corner seal 4 the four corners of bag b, fold it inward from both sides in a pleated shape and do this along the folded edges on the outside, as shown in Figure 2. This is done in the bag making process.

The spout body a may be a plastic injection molding as shown in FIGS. 3 and 4, or sometimes a draw molding of aluminum or tin as shown in FIG.

The one shown in Fig. 3 is the mouth part body a shown in Fig. 1.
The upper surface of the mouth rim 1 is made of paper/
It is sealed with Al/sealant or a sheet having barrier properties (hereinafter referred to as barrier sheet) 5.

The one shown in FIG. 4 is called an ultra-lock system, in which a protrusion 7 is provided on a part of the mouth edge 6 of the mouth body a, and this part has a thinner part 8 from below. The lid 9 is attached to the bag attachment part 10 of the mouth body a.
The flange 11 of the flange 11 is bonded to the protrusion 7 of the mouth edge 6. When opening the lid, the protruding part 7 is pinched and separated from the thin wall part 8. However, since the lid 9 is slid together with the bag attachment part 10 of the mouth edge 6, it is difficult to open the lid after opening. It can also be covered well.

The one shown in FIG. 5 is a draw-molded product made of aluminum or tinplate, and the bottom plate 12 has an opening 13, which is sealed with a barrier sheet 14.

As mentioned above, the mouth main body a can have various structures such as injection molded plastic or draw molded aluminum or tin, but the main point is that the mouth of the molded product can be formed as shown in Figure 1. On main body a, 4
The present invention is characterized by a composite container A for holding slurry such as miso, which is equipped with a bag body b whose corners are sealed 4 to provide buckling strength.

Such a composite container is commercially available and filled with a slurry such as miso.

(Effects of the invention) The present invention is a composite container with the above structure, but when the contents are filled and sealed, the center part bulges out because the four corners of the bag body are corner-sealed. It has better shape retention than conventional plastic bags filled with contents and sealed, and is convenient when packing a large number of items in a box.

In addition, the user can easily take out the contents with a spoon, spatula, chopsticks, etc. after opening the mouth part of the mouth part body, and even after taking out the contents, the rim of the mouth can be easily removed like a conventional squeezer. Since there is not much adhesion to the inside, it feels clean and hygienic.

Moreover, since the bag body is given buckling strength by corner seals, it can remain upright as a container even when the contents are low.
It is extremely convenient to use in combination with the mouth part body of the molded product.
