Description

[Detailed explanation of the invention] This invention combines coffee or tea, sugar, and milk powder into one
This invention relates to a packaging bag that can be packaged as a set.

Conventional bags of this type package coffee or tea, sugar, and milk powder individually, which requires a large amount of packaging material, increases the heat sealing process, and is inconvenient to handle. Met.

This invention was devised in view of the above-mentioned circumstances, and one embodiment thereof will be described below with reference to the drawings.

A tubular bag body A for containing sugar a, which is constructed by polymerizing packaging materials 2, 2 made of two rectangular polyethylene films 1, 1 and bulging the central portions of each to the outside;
A tube-shaped coffee or tea powder container made by rolling a rectangular packaging material 6, which is laminated with polyethylene film 3 on the inside, aluminum foil 4 on the center, and paper 5 on the outside, so that the polyethylene film 3 is located on the inside. It consists of a bag body B for storing milk powder C, and a bag body C for containing milk powder C, which has the same structure as bag body B. The insides of the remaining film ends 3a, 3a are respectively polymerized, and the polymerized parts and the upper and lower openings of the bags A, B, and C are respectively heat-sealed, and a perforation 7 is carved in the center of the polymerized parts. This is a packaging bag.

Since this invention is constructed as described above, it has the following effects.

(1) Bag A for holding sugar A, bag B for holding coffee or tea soup, and bag C for holding milk powder C are in one set, so each bag is one piece. Compared to separate packaging, packaging materials can be saved and handling is convenient.

(2) A bag body A is made up of packaging materials 2 and 2 made of polyethylene films 1 and 1 in the center, and packaging materials 6 that are laminated with polyethylene film 3, aluminum foil 4, and paper 5 on both sides. Because the bags B and C are placed in the bag, sugar a, which has relatively low hygroscopicity, is placed in the center bag A, and coffee or tea powder and milk powder C, which are highly hygroscopic, are placed in the bags B and C on both sides. By storing them in C, they can be stored for a fairly long period of time.

(3) The inner sides of the remaining film ends 3a, 3a of bags B and C, that is, the polyethylene films, are polymerized on the outside of the remaining film ends 1a, Ia on both sides of bag A, so that heat sealing can be easily performed.

(4) In the case of a conventional single bag for storing coffee powder, for example, the packaging material is rolled into a tube shape, the overlapping ends of which are heat-sealed, and then the sealed portion is bent to one side and heated again to the bag surface. Since it is a so-called envelope pasting method, it is necessary to place polyethylene film on both the inside and outside of the packaging material, but with this invention, only the inside is coated with polyethylene film, which saves material costs and eliminates the heat sealing process. One step can be omitted.

(5) Bag A for holding sugar A, bag B for holding coffee or tea, and bag C for holding milk powder C are integrally formed. Since the perforations 7 are cut in between, it is easy to separate.

Thus, the packaging bag according to this invention is suitable not only for home use but also as a beverage pack for cafeterias on trains and the like.
