However, in the conventional packaging bag, since the length of the band-shaped film constituting the handle portion is constant, the handle portion of the packaging bag becomes difficult to hold when the capacity and weight of the object to be packaged become large, and the handle portion of the packaging bag becomes difficult to hold. Sometimes it is difficult to carry it with other luggage. In addition, it can be painful and burdensome to carry.

An object of the present invention is to provide a packaging bag that is easy to carry.

The first aspect according to the present invention has a main body portion in which a packaged object is housed and a handle portion formed on the top surface of the main body portion, and both ends of the handle portion are the main body. The handle portion is formed of a strip-shaped film joined to the portions, and the handle portion has a folded portion in which a part of the strip-shaped film is folded, and the folded portion joins the folded portions in the thickness direction. A packaging bag having a temporary fixing portion is provided.

In the first aspect, a part of the strip-shaped film constituting the handle portion of the packaging bag is folded at the folded portion of the handle portion, and further temporarily fixed by the temporary fixing portion of the folded portion. In such a configuration, when you want to hold the handle part as it is (for example, when you hold the handle part with your hand or finger, it is also referred to as unintended below), you can hold the handle with a part of the band-shaped film folded. You can have a part. In addition, when you want to hold the handle part for a long time (for example, when you put your arm through the handle part or hang the handle part on your shoulder, it is also referred to as the intention below), temporarily fix the temporary fixing part. The handle can be lengthened by removing (or releasing).

As a result, in the first aspect, when the capacity or weight of the packaged object is large, or when the packaged object is carried together with other luggage, the length of the handle portion is increased according to the physique and physical strength of the user who carries the package bag. You can adjust the weight. Therefore, according to the first aspect, it is possible to provide a packaging bag that is easy to carry.

By releasing the temporary fixing of the portion or the second folding portion, the length of the handle portion can be slightly increased (for example, the arm is passed through the handle portion). Further, if the temporary fixing of the first folded portion and the second folded portion is released together, the length of the handle portion can be maximized (for example, the handle portion can be hung on the shoulder). Therefore, according to the fourth aspect, the length of the handle portion can be adjusted stepwise.

A fifth aspect of the present invention provides a packaging bag in which the folded portion is composed of a first folded portion and a second folded portion that overlap in the thickness direction. In the fifth aspect, as the folding portion of the handle portion, the first folding portion or the first folding portion is formed by arranging the two folding portions including the first folding portion and the second folding portion so as to overlap each other in the thickness direction. The temporary fixing of the second folded portion can be released, and the temporary fixing of the first folded portion and the second folded portion can be released together. Therefore, also in the fourth aspect, the length of the handle portion can be adjusted stepwise.

A sixth aspect according to the present invention is that the first folded portion has an exposed portion in which the first folded portion is arranged below the second folded portion and a part of the first folded portion is exposed, and the provisional portion is provided. The stop portion includes a first temporary fixing portion formed in the exposed portion and joining the first folded portion in the thickness direction, and the first folded portion and the second folded portion in the thickness direction. Provided is a packaging bag composed of a second temporary fixing portion to be joined.

In the sixth aspect, a second temporary fixing is composed of a first folding portion and a second folding portion in which the folding portions overlap in the thickness direction, and the first folding portion and the second folding portion are temporarily fixed. A first temporary fixing portion for temporarily fixing the first folding portion to the portion is formed in the exposed portion of the first folding portion. This makes it easy to release the first temporary fixing portion of the first folding portion and the second temporary fixing portion of the second folding portion separately. Therefore, according to the sixth aspect, it becomes easier to adjust the length of the handle portion step by step.

A seventh aspect according to the present invention provides a packaging bag in which the folded portion overlaps the side surface of the main body portion. In the seventh aspect, since the folded portion of the handle portion is arranged so as to overlap the side surface of the main body portion of the packaging bag, it is difficult for the hand or finger to directly hit the folded portion when holding the handle portion. Therefore, when you want to hold the folded part while temporarily fixing it (when you do not intend), you can easily grasp the handle part. Further, since the folded portion is not grasped when holding the handle portion in this way, the temporary fixing of the folded portion is difficult to come off when it is not intended.

As a test body, five thin paper cartons (packaged body) TCs are stacked in five stages in the vertical direction, covered with a main body portion 10 (wrapping film) formed in a tubular shape, and the top and bottom thereof are sealed by caramel packaging. A stopped packaging bag 100 was prepared. A handle portion 20 formed of a strip-shaped film BF was provided on the top surface 11 of the main body portion 10 of the packaging bag 100. In the handle portion 20 (strip film BF), the end portion 21 is joined to the side surface 13a of the first side surface 13, and the end portion 22 is joined to the side surface 13a of the first side surface 13. The main body portion 10 (wrapping film) was formed of a polyethylene resin film having a thickness of 25 μm, and the handle portion 20 (belt-shaped film BF) was formed of a polyethylene resin film having a thickness of 48 μm. For the thin paper carton TC, a tissue carton (“Eliere tissue” dimensions manufactured by Daio Paper Corporation: length: about 197 mm, width: about 229 mm, height: about 62 mm, 360 sheets (180 sets)) was used.

[Pendulum test]
The user can freely hang his / her finger on the handle portion 20 of the packaging bag 100 to hold the packaging bag 100 and move it back and forth 10 times like a pendulum within a range of 180 ° to temporarily fold the folding portion 30 (and the folding portion 50). It was confirmed whether the stop was released (disengaged). The test was performed 5 times for each example and comparative example, and evaluated according to the following criteria. As for the comparative example, the pendulum test was not performed because the temporary fixing was not provided (measurement impossible "-").
◯: Temporary fixing did not come off even once out of 5 times (temporary fixing was not unintentionally released)
×: Temporary fixing came off at least once out of 5 times (temporary fixing was unintentionally released)

[Easy to hold]
Regarding the packaging bag 100, it was confirmed whether the user can hold the handle portion 20 (grasping by hand, passing the arm, hanging on the shoulder, etc.) with all the temporary fixing portions 40 temporarily fixed open. It describes how you can have it.
◎: Can be hung on the shoulder ○: Cannot be hung on the shoulder, but can pass through the arm ×: Can only be grasped by hand

[Tensile strength]
The tensile strength of the test piece (packaging bag 100) was measured. In the measurement of tensile strength, a push-pull gauge (“DSP-20” manufactured by IMADA) was first attached to a tensile tester (“MX-500N” manufactured by IMADA). In addition, clips (film chuck (FC21) manufactured by IMADA) were attached to the push-pull gauge and the chuck mounting plate, respectively. Each clip was fixed to the test piece so that the width between the push-pull gauge and the clip attached to the chuck mounting plate was 30 mm. The fixed position of the clip is such that the temporarily fixed portion 40 (third fused portion 43) and the temporarily fixed portion 40 (first fused portion 41) of the test piece are arranged on the clip located below, and the clip is fixed above. The handle portion 20 (end portion 21 side) is arranged on the clip located at. Then, a clip was pulled in the direction in which the temporary fixing portion was opened at a speed of 100 mm / min, and the strength (peak) was measured. The tensile strength was measured three times, and the average value (kgf) was calculated as the tensile strength. It was evaluated as good when the average value of the tensile strength was less than 1.5 kgf. In the comparative example, since the temporary fixing was not provided, the strength (peak) when the joint portion between the end portion 21 of the handle portion 20 and the first side surface 13 of the main body portion 10 was broken was measured. In the measurement of the comparative example, the fixed position of the clip is the main body portion in which the unbonded portion of the end portion 21 of the test piece is arranged in the clip located below and the end portion 21 is joined to the clip located above. 10 (wrapping film) was arranged.

Hereinafter, Examples and Comparative Examples will be described.

In the packaging bag 100, the handle portion 20 is provided with a folded portion 30 in which a part FP of the strip-shaped film BF is folded, and a temporary fixing portion 40 for temporarily fixing the folded portion 30. Further, four fused portions 41 to 44 as temporary fixing portions 40 of the folded portion 30 are arranged at the four corners (corner portions 30c to 30d) of the folded portion 30. The packaging bag 100 was evaluated by performing a pendulum test and a tensile test. The results are shown in Table 1.

[Example 2]
The packaging bag 100 of the second embodiment shown in FIGS. 6 and 7 was prepared. In this packaging bag 100, as the folding portion 30 of the handle portion 20, two folding portions 30 including the first folding portion 30 and the second folding portion 50 are provided in the longitudinal direction (X direction) of the strip-shaped film BF. The packaging bag 100 was prepared and evaluated in the same manner as in Example 1 except that the packaging bags were arranged side by side. The results are shown in Table 1.

[Example 3]
The packaging bag 100 of the third embodiment shown in FIGS. 8 and 9 was prepared. In this packaging bag 100, the folded portion 30 is composed of a first folded portion 30 and a second folded portion 50 that overlap in the thickness direction (Z direction), and the first folded portion 30 and the second folded portion 50. Example except that the first temporary fixing portion 40 for temporarily fixing the first folding portion 30 is formed in the exposed portion EP of the first folding portion 30 with respect to the second temporary fixing portion 60 for temporarily fixing the above. A packaging bag 100 was prepared and evaluated in the same manner as in 1. The results are shown in Table 1.

[Example 4]
The packaging bag 100 of the fourth embodiment shown in FIG. 10 was prepared. In this packaging bag 100, the packaging bag is the same as in the first embodiment except that the folded portion 30 of the handle portion 20 is arranged so as to overlap the first side surface 13 (side surface 13b) of the main body portion 10 of the packaging bag 100. 100 was made and evaluated. The results are shown in Table 1.

[Comparison example]
The conventional packaging bag 100 shown in FIG. 11 was prepared. In this packaging bag 100, the packaging bag 100 was produced and evaluated in the same manner as in Example 1 except that the handle portion 20 was not provided with the folding portion 30 and the temporary fixing portion 40. The results are shown in Table 1.

From Table 1, in the packaging bag 100 in which the handle portion 20 is provided with the folded portion 30 in which a part of the band-shaped film BF is folded and the temporary fixing portion 40 for temporarily fixing the folded portion 30. In each case, the result of the pendulum test was 〇, the ease of holding was 〇 or ⊚, and the tensile strength was less than 1.5 kgf (Examples 1 to 4).

On the other hand, in the packaging bag 100 in which the handle portion 20 is not provided with the folding portion 30 and the temporary fixing portion 40, the result of the pendulum test is ○ because there is no temporary fixing, but the ease of holding is ×. Yes, the tensile strength exceeded 1.6 kgf (comparative example).

Further, from the results of the tensile test, the force required to release the temporary fixing in Examples 1 to 4 was smaller than the force at which the joint portion between the handle portion and the main body portion was broken (comparative example). ..

From these results, if it is not intended, it is possible to form a folded part in which a part of the band-shaped film is folded in the handle part of the packaging bag, and to form a temporary fixing part to be joined in the thickness direction to the folded part. It was found that the temporary fixing of the folded part is not released, and the temporary fixing of the folded part can be released only when it is intended (a packaging bag that is easy to carry can be obtained). It was also found that the temporary fixing of this folded part can be released with a weak force.

Although the embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the invention described in the claims. ..
