Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a double bag having two chambers each having a separate opening and containing powdered or liquid food, and the double bag. Relating to a method of manufacturing.

[Conventional technology]

In this particular field, it is known that food products are stored in a dry, powdered form, so that they can be prepared immediately by heating or cooking in a suitable liquid, such as water. In some cases, the store contains two different foods prepared in two successive steps, each of which is placed in both chambers of the double bag. However, this bag has only one opening that uses two chambers at the same time. As a result, all of the food is used at once, and one of the two cannot be stored separately.

Using this type of double bag, it is not possible to separate two doses of the same food or the same type of product at different times, and the second dose is kept in the storage state before opening the first chamber. cannot be kept.

[Problem of invention]

The object of the invention is to overcome the above-mentioned difficulties by providing a double bag with separate openings for each chamber, which is compact in shape and is easy and economical to manufacture and fill.

Furthermore, another object of the present invention is to provide a method for manufacturing the above-specified double bag.

[Means to solve problems]

The structure of the invention of this application to solve the above problems will be explained using FIGS. 1 to 3 corresponding to the embodiments. In a double bag with separate openings, the inner wall and the outer wall are formed of a thin film-like sheet sealed at their edges B, B. , this bag is constituted by a first sheet which is folded at a folding edge A-A to form two outer walls, said outer walls 3, 4 being symmetrical with respect to the edge A-A and
- two auxiliary folds 8 folded opposite to A;
9, the auxiliary folds form two tongues, and the inner walls 5, 5a, 5b are formed by a second sheet and have two sealing lines extending parallel to the edges A-A. 6, 7 to the outer walls 3, 4, and after the portions of the inner walls 5, 5a, 5b outside the sealing lines 6, 7 are inserted inside the two tongues, respectively. , at least one of its outer parts is folded back at a fold 10 and extends between the outer walls 3, 4 to partition the two chambers 1, 2, said two tongues are connected to both sealing lines 6, 7 and to both auxiliaries. Between the folds 8 and 9 there are breaks D1 and D2 for the two chambers 1 and 2, respectively, parallel to the edge A-A. Also,
The invention of the method for manufacturing a double bag of this application is, in the method for manufacturing a double bag, placing the first sheet forming the outer walls 3 and 4 on a flat surface to determine a folding edge A-A; The second sheet forming the inner walls 5, 5a, 5b is sealed against the outer wall by two sealing lines 6, 7, the outer wall and the inner wall are folded at the edge A-A,
Further, the first sheet is folded back symmetrically with respect to the edge A-A at auxiliary folds 8 and 9 in a direction opposite to the edge A-A to form the two tongue portions, and then an edge B perpendicular to the edge A-A is formed. , B to seal both sheets.

〔Effect of the invention〕

An advantage of the present invention is that, with the above-described configuration, the openings can be provided separately in the two chambers, and the openings can be easily created by the broken portion, and the food in the two chambers can be selectively used. In addition, the leftover food can be completely undamaged and maintained in its original storage state until the next use.

Furthermore, since the structure is simple, the manufacturing method is easy and continuous manufacturing is possible.

〔Example〕

The features and advantages of the invention will now be explained in more detail with reference to the accompanying drawings.

In the embodiment shown in FIGS. 1 and 2, the double bag according to the invention consists of two chambers 1, 2 separated by an outer wall 3, 4 and an inner wall 5a, 5b, said inner wall being common to the two chambers. It is. The outer walls 3 and 4 are folded edges A-
It consists of a single first sheet folded along A. Further, the outer wall has two auxiliary folds 8, 9 that are symmetrical with respect to the edge A-A and folded oppositely to the edge A-A, and the auxiliary folds 8, 9
It forms two tongues.

The inner walls 5a, 5b are formed of a second sheet and are sealed to the outer walls 3, 4 by two sealing lines 6, 7 extending parallel to the ridge A-A. The outer parts of the sealing lines 6 and 7 are respectively inserted inside the two tongues, and the fold line 1
0, and its extension extends between the outer walls 3 and 4 to form double inner walls 5a and 5b to partition the two chambers 1 and 2. The bag with the general symbol 11 is, for example, rectangular, and the edges B, B of the sheet forming this rectangle are glued or welded by a known method. Between the sealing lines 6, 7 of the tongues on both sides and the auxiliary folds 8, 9 there are breaks D1, D2 for the two chambers 1, 2, respectively, parallel to the ridge A-A; Cuts 12 are provided in each of the portions D1 and D2 so that openings can be easily created.

In another embodiment, shown in FIG. The distal end of the folded and folded sheet is inserted into the tongue on the side of the other auxiliary fold 9.

To make a double bag according to the invention, one first sheet forming the outer wall is placed on a flat surface, a folding edge A-A is defined, and two seals parallel to the edge A-A are placed. The second sheet forming the inner wall is sealed to the first sheet by means of the sealing lines 6,7. Next, fold both the first and second sheets along the edges A-A,
Furthermore, the first sheet is folded symmetrically with respect to the edge A-A in the direction opposite to the edge A-A at auxiliary folds 8 and 9 to form the two tongue portions, and then the edge B perpendicular to the edge A-A is folded back. , B, both sheets are sealed. In this state, the bottom of the double bag has broken parts D1 and D2.
Since the chambers 1 and 2 are formed by the sections 1 and 2, each of the chambers 1 and 2 can be filled with contents. After filling, the side opposite to the ridge A-A is filled by an appropriate means.
For example, the sealing can be done by folding the ends of the inner wall and the ends of one outer wall 3 over the ends of the other outer wall 4 along the folds 15.

These walls are made of a suitable sheet material, such as impermeable paper, metallic paper, or metal or plastic material. In the case of plastic materials, the sealing is done by heat welding. When the bag is filled and sealed, it is more convenient for storage if the folded portion 15 is also formed at the bottom of the bag.

According to this invention, after one or the other chamber is opened, the food in the closed chamber can be maintained in its original storage state until it is used. Particularly in the case of cooked foods, the invention enables safe consumption guaranteed by the packaging description (ingredients, directions for use, storage conditions, labeling and marking);
Enclosed food remains intact until it is used.

The foregoing description is merely for the purpose of illustrating the present invention, and the present invention is not limited to what is shown in the drawings, and modifications particularly useful in the same technical field may be made without departing from the gist of the invention. Of course it is possible.
