Description

[Detailed description of the invention] (Industrial field of application) The present invention is used in the technical field of manufacturing and selling packaging materials with a simple structure, which are mainly used as shopping bags in daily life.

(Prior art) Conventionally, sheet-like packaging materials such as wrapping paper and furoshiki have been most commonly and widely used as packaging materials for carrying circular-shaped items while maintaining their horizontal state. However, in both cases, not only is it time-consuming and complicated manual work to hold the packaged items horizontally, but especially in the case of wrapping paper, it is difficult to carry them horizontally after wrapping. There were problems with poor workability, such as the need to tie the string in a well-balanced manner.

In order to deal with the above problem, the inventors of the present invention conducted various researches and found that they first layered two sheets of plastic film, cut them into a circular shape, welded and sealed the cut line, and An application for a packaging material in which two side hand pieces and two opposing fixing pieces are formed by making an X-shaped cut in the side material, and an opening for insertion of fingers is formed in each side hand piece. No. 56-50438), the above problems were solved at once, and the packaging of circular objects was facilitated.
It has succeeded in ensuring that it can be carried while maintaining a horizontal position, and has achieved great popularity and results.

However, in the case of the above-mentioned packaging material, since the cuts are cut in an X shape, the straight cuts tend to tear from the ends, and the disadvantage is that it is difficult to carry heavy items by inserting the fingers into the finger insertion opening. When the device is opened, the thin plastic film material becomes like a thin string and bites into the hands and fingers, causing severe itching and making it difficult to carry. It has been confirmed that there are drawbacks in that the packaged items can easily escape and foreign objects can easily get inside.

(Purpose of the present invention) The present invention was completed in order to eliminate one of the three drawbacks mentioned above. When the device is pressed, the extra portion above the finger rest is regulated so that it is naturally positioned flat, and is configured so that it comes into contact with the fingers widely, making it soft and comfortable to carry without causing any itchiness. The purpose is to provide a carrier bag with advantages.

(Structure of the present invention) In the present invention, the main body of the carrier bag is constructed by bonding the peripheral edges of two overlapping circular plastic film materials, and the upper material has a cut along the diameter direction. In a carrier bag in which the left and right carrier pieces are divided by the cut, and each carrier piece is provided with a finger hook, the required range of each adhesive peripheral edge of the multilayer material facing both ends of the cut is The present invention relates to a carrier bag characterized by being formed in a straight line.

(Function of the present invention) When the article to be packaged A is stored in a carrier bag and hung, the lower material 4 is pushed down. At this time, a force _P1 that tries to shrink the outer periphery of the upper and lower materials 3 and 4 as a whole is generated in a direction (centripetal direction) perpendicular to the adhesive periphery of the materials, as shown in Figure 3, and this force Due to _P1 , the upper material 3 tends to shrink toward the center and wrinkles occur, and at the same time, the left and right hand pieces 6, 6 come together toward the center.

On the other hand, the multilayer material 3 facing both ends of the cut 5,
Since the required range of each bonding peripheral part 4 is formed in a straight line, the force P2 applied to the straight part ₂ is equal to the edge of the straight part 2, as shown in FIG. They act parallel to each other in orthogonal directions. Therefore, the upper part 7 from the finger hook part 8,
In the portion 7, the wrinkles that occur when the upper material 3 tries to shrink toward the center due to the force P ₁ are stretched by the force P ₂ , and as a result, the remaining pieces 7, 7 portion The wrinkles will be removed and the flat state will be maintained.

(Embodiments of the present invention) Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. 1 is a carrier bag body, which is made of multilayered polyethylene films, and has a required range of opposing peripheral edges ( It is constructed by gluing the peripheries of two irregularly circular plastic film materials 3 and 4, each of which has a linear portion (required dimension length) and has linear portions 2, 2 facing each other. In this case, the two wide sheets of the materials 3 and 4 are layered, cut into the above irregular circular shapes at multiple locations, and at the same time, the periphery is welded and sealed, thereby producing a large number of carrier bag bodies 1 at the same time. It is something. Reference numeral 5 denotes a cut cut along the diameter direction in the material 3 above the carrier bag main body 1, with both ends of the cut facing each other at intermediate positions of the linear parts 2, 2. In this embodiment, two gently curved cuts 5a, 5a are cut so as to intersect in the center in a cross-shaped manner, and arc-shaped cuts 5b, 5b are formed at both ends of both cuts 5a, 5a. By providing a cut 5 in a state in which they are connected to each other, the cut portion is removed from the material 3. Thus, the cut 5 consisting of the cuts 5a and 5b divides the left and right hand pieces 6, 6 into the material 3, and at the same time, an extra piece 7, is formed on the upper edge of the central part of each hand piece.
7 remains and finger hooks 8, 8 made of through holes, cuts, perforations, etc. are provided to constitute a carrier bag.

Note that the shape of the cut 5 is not limited to that of the above embodiment, and although not shown, the shape of the cut 5 is not limited to the shape of the material 3.
A single linear cut may be provided in the diametrical direction, and the cut may be a perfect circular cut that curves outward of the material and is continuous at both ends of the linear cut. In short, the arcuate cuts are made at both ends of the cut along the diameter of the material and curved outwards of the material, effectively reducing the tearing force applied to the ends of the cut when carrying the material. It should be of a type that can be absorbed into the body.

(Effects of the present invention) The carrier bag according to the present invention configured as described above has both hand pieces 6, 6 opened on both sides from the cut 5, and a required circular cover is placed on the lower material 4. After inserting and storing the package A, the two-hand holding piece 6,
It is carried and used using the finger hooks 8, 8 of 6, and its unique structure makes it possible to wrap (storage) circular items horizontally compared to the wrapping paper and wrapping paper mentioned above. This makes it much easier and more reliable to carry the package while keeping it in the same position, and when carrying it, it is possible to carry the packaged item while maintaining it in an extremely stable horizontal position, as shown in Figure 2. In addition, since the upper and lower substantially circular materials 3 and 4 can naturally follow the cylindrical circumferential side of the packaged object, the appearance and horizontal stability are improved compared to the aforementioned U-shaped and V-shaped cross-sectional carrying bags. In addition to being extremely excellent in retention, it is easy to manufacture and can be mass-produced at low cost.

Furthermore, in addition to the above-mentioned effects, the present invention also has the following advantages:
As shown in Fig. 2, the required area of each adhesion peripheral edge of the multi-layered material facing both ends of the cut is formed in a straight line to provide a straight line. When carrying with one's fingers on the finger rest, the extra parts 7, 7 above the finger rest can be regulated to naturally lie flat, and the extra parts are wide enough to fit the fingers. Since the device comes into contact with the device, it has the great advantage of being soft and easy to carry without causing any itching in the hands or fingers.
