Description

Packaging and packaging manufacturing methods

This invention relates to a method of making packaging and packaging.

Various types of packaging have been developed in the packaging used to package the packaged articles. When the packaged object is, for example, a cigarette, the package is configured to prevent the odor from adhering to the cigarette or the cigarette to be damp, and the package is sealed by sealing the cigarette. The package is not limited to cigarettes, and a package that can be sealed by contact with air or the like is also required.

For example, in the conventional cigarette package, a cigarette as a packaged article is packaged by paper or the like, and the outer side of the cigarette package is sealed by a gas barrier plastic film or the like, or a gas-resistance plastic film is used. The cigarette is sealed and sealed, and the outer surface is packaged and protected by paper or the like (for example, refer to Patent Document 1 and Patent Document 2). In other words, conventional cigarettes are packaged in two layers by packaging of paper or the like and packaging of a plastic film or the like.

A package in which the conventional packaging has been simplified is known in which a cigarette is packaged using only one layer of packaging (for example, refer to Patent Document 3 and Patent Document 4). Patent Document 5).

The second opening 37 communicates with a first opening 36 (see FIG. 8 ) which is formed between the front surface portion 22 and the upper surface portion 21 .

Next, as shown in FIG. 8, the first folding portion 27 and The second folding portion 28 is folded back toward the upper surface portion 21, and the package 20 is changed to the second state. In the second state, the first side end seal portion 33 and the second side end are provided When the portion sealing portion 34 is pressed toward the direction in which the portions are close to each other, that is, in the direction toward the central portion of the package 20, the first folded portion 27 and the second folded portion 28 are deflected, and the second opening 37 is opened. .

As shown in FIG. 9, in the state in which the second opening 37 is opened, The cigarette as the packaged object can be taken out through the first opening 36 and the second opening 37. Further, since the second reflexed central portion 28c, the second reflexed first side surface portion 28a, and the second reflexed second side surface portion 28b are formed of a transparent or translucent sheet, the inside of the package 20 can be easily recognized. And it is easy to take out the cigarette 40 from the package 20.

As shown in Fig. 10, after the cigarette 40 is taken out from the package 20, By folding the first folding portion 27 and the second folding portion 28 toward the front portion 22, the package 20 is changed to the state in which the first opening 36 is closed, that is, the first state is changed.

Next, the package 20 of the present embodiment has The role is explained. The package 20 of the present embodiment has a first folded-back central portion 27c, a first folded-back first side surface portion 27a, and a first folded second second side surface portion 27b. Therefore, in a state in which the state of the package 20 is extended upward from the first folding portion 27 shown in FIGS. 8 and 9 (second state), the first folding portion 27 is folded back toward the front side. When the first folding portion 27 shown in FIG. 10 is folded back toward the front side (the first state), the first folding portion 27 is directed in the opposite direction to the direction of the folding, and is subjected to the first reaction. The resistance generated by the tension of the first side surface portion 27a and the first folded second side surface portion 27b is folded. Therefore, the package 20 of the present embodiment has an effect of maintaining the second state.
