Description

Package and package manufacturing method

The present invention relates to a package and a method for manufacturing the package.

Conventionally, various types of packages have been developed as packages for packaging an object to be packaged. When the packaged object is, for example, a cigarette, the package is configured so that the cigarette can be hermetically sealed in order to prevent odor from adhering to the cigarette, moisture absorption of the cigarette, and the like. There is a need for a package that can be hermetically sealed and packaged even for objects to be packaged whose properties can be changed by contact with an air atmosphere or the like without being limited to cigarettes.

For example, in a conventional cigarette package, a cigarette that is an object to be packaged is wrapped with paper or the like, and the outside is wrapped and sealed with a plastic film having a gas barrier property, or the cigarette is sealed with a plastic film having a gas barrier property or the like. It is packaged and sealed, and its outer surface is packaged and protected with paper or the like (see, for example, Patent Document 1 and Patent Document 2). That is, the conventional cigarette is double-wrapped by packaging of paper or the like and packaging of plastic film or the like.
As a simplified package of conventional packaging, it is known to package a cigarette only by a single package (see, for example, Patent Document 3, Patent Document 4, and Patent Document 5).

Located in. Here, an intersection point of the second side surface portion 29b, the upper surface portion 21, and the front surface portion 22 is defined as an intersection point P3. When the linear distance between the arbitrary point P1 and the intersection point P3 is x and the linear distance between the intersection point P3 and the arbitrary point P2 is y, the length of the connecting member 41 is the length x and the length. It is configured to be smaller than the sum of y.

In the package 20 ′ configured as shown in FIG. 11, when trying to fold the first folded center portion 27 c upward, that is, when changing from the first state to the second state, the connection member 41 The tension T1 is generated in the direction substantially opposite to the direction in which the first folded center portion 27c is pulled. Therefore, the package 20 'exerts an action to maintain the first state by the tension T1.

As shown in FIG. 12, when the package 20 ′ in the second state is about to change to the first state, the connection member 41 is substantially opposite to the direction in which the first folded center portion 27c is pulled. A tension T2 directed in the direction is generated. Therefore, the package 20 'exerts an action for maintaining the second state by the tension T2.

If the length of the connecting member 41 is equal to or greater than the sum of the length x and the length y, the connecting member 41 will bend and the tension T1 and tension T2 shown in FIGS. 11 and 12 will not be generated. Or very weak. The package 20 shown in FIGS. 1 to 10 has the connection member 41 shown in FIGS. 11 and 12 in a first folded first side surface portion 27a, a first folded second side surface portion 27b, and a second folded first side surface portion. 28a and a part of the second folded second side surface portion 28b. For this reason, the package 20 has the effect | action which tries to maintain a 1st state and a 2nd state.

Covered by the portion 24, the back surface portion 23, and the upper surface portion 21. Subsequently, the bottom-side first side surface portion 24a is folded back with respect to the first side surface of the packaged object to cover at least a part of the first side surface of the packaged object. Similarly, the bottom side second side surface portion 24b is folded back with respect to the second side surface of the packaged object to cover at least a part of the second side surface of the packaged object.

Subsequently, the upper surface side first side surface portion 21a is folded back with respect to the first side surface of the packaged object to cover at least a part of the first side surface of the packaged object. Similarly, the upper surface side second side surface portion 21b is folded back with respect to the second side surface of the packaged object to cover at least a part of the second side surface of the packaged object. Further, the front side first side surface portion 22a is brought into close contact with the bottom side first side surface portion 24a, the back side first side surface portion 23a, and the upper surface side first side surface portion 21a, for example, by heat sealing. This closely contacted portion corresponds to the first side seal portion 31. Similarly, the front surface side second side surface portion 22b is brought into close contact with the bottom surface side second side surface portion 24b, the back surface side second side surface portion 23b, and the upper surface side second side surface portion 21b by, for example, heat sealing. This closely contacted portion corresponds to the second side seal portion 32.

Subsequently, the side end portion of the first folded first side surface portion 27a extending from the first folded center portion 27c and extending from the upper surface side first side surface portion 21a extends from the second folded center portion 28c. And it is made to contact | adhere to the side edge part of the 2nd folding | turning 1st side part 28a extended from the front side 1st side part 22a, for example by heat sealing. This closely contacted portion corresponds to the first side end seal portion 33.

Similarly, the side end portion of the first folded second side surface portion 27b extending from the first folded center portion 27c and extending from the upper surface side second side surface portion 21b extends from the second folded center portion 28c.

This closely contacted portion corresponds to the end seal portion 35 (see FIGS. 1 to 5).

As described above, it is possible to manufacture a package 20 that can be packaged by sealing an object to be packaged, without having to cut and paste the sheet material from a single substantially rectangular sheet material. That is, the package 20 can be manufactured at low cost and at low resources.

FIG. 14 is a schematic perspective view showing a reinforcing material that can be additionally used for the package 20. After the package 20 is opened and a part of an article to be packaged such as a cigarette is taken out, a gap is formed inside. Depending on the strength of the material forming the package 20, it is difficult to maintain the shape of the package 20 due to the gap.

In order to maintain the shape of the package 20 even after a part of the package is taken out, the package 20 can additionally include a reinforcing member 50 shown in FIG. The reinforcing member 50 is made of, for example, paper having a predetermined rigidity, and is formed in a cup shape corresponding to the shape of the package 20. An article to be packaged such as a cigarette is packaged in the package 20 while being accommodated in a cup-shaped reinforcing material 50. That is, the reinforcing material 50 is packaged in the package 20 together with the packaged object. The article to be packaged packaged in the package 20 while being accommodated in the reinforcing member 50 can be taken out from the package 20 through the first opening 36 and the second opening 37 of the package 20.

It has the 1st return | turnback 1st side part 27a extended from the upper end part of 29a. Thereby, since the 1st state or the 2nd state is maintained as mentioned above, even after it is opened, the closed state can be held. As a result, with a simple configuration, it is possible to hold the non-packaged item even after opening, and to suppress contact between the air atmosphere and the non-packaged item.

The package 20 according to the present embodiment is configured to be able to be folded back toward the front surface portion 22 so that the first folded center portion 27c overlaps at least a part of the front surface portion 22, and the first folded first The side surface portion 27a is configured to be able to be folded back toward the first side surface portion 29a so as to overlap at least a part of the first side surface portion 29a. That is, it is possible to change from the state in which the first folded portion 27 extends upward (second state) to the state in which the first folded portion 27 is folded back (first state). Thereby, the package 20 can change between the first state and the second state while maintaining the first state or the second state.

Further, the package 20 according to the present embodiment has a first opening 36 for taking in and out the package between the upper end portion 22c of the front surface portion 22 and the front end portion 21c of the upper surface portion 21. Therefore, after the package 20 is opened, the package object can be easily taken in and out from the first opening 36 having a size sufficient for taking the package object in and out.

Thereby, the package 20 can have appropriate flexibility for folding the first folded portion 27 and the second folded portion 28. When the weight per unit area of the plastic film material forming the package 20 is less than 0.01 g / m ² , the rigidity of the package 20 becomes too low, so the first state and the second state are maintained. The effect is too small. In addition, when the weight per unit area of the plastic film material forming the package 20 exceeds 0.5 g / m ² , the rigidity of the package 20 becomes too high, so the first folded portion 27 and the second folded portion 28 are provided. It becomes difficult to wrap.

Further, the package 20 according to the present embodiment is formed from a sheet material having a thickness of 12 μm or more and 500 μm or less. Thereby, the package 20 can have appropriate flexibility for folding the first folded portion 27 and the second folded portion 28. When the sheet material forming the package 20 is a paper material and the thickness is less than 50 μm, and when the sheet material forming the package 20 is a plastic film material and the thickness is less than 12 μm, Since the rigidity of the package 20 becomes too low, the effect of maintaining the first state and the second state becomes too small. Further, when the sheet material forming the package 20 is a paper material or a plastic film material and the thickness thereof exceeds 500 μm, the rigidity of the package 20 becomes too high, and therefore the first folded portion 27 and the second folded portion 28. It will be difficult to wrap.
