DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag having a handle in a bag made of synthetic resin, and more specifically, a handle extending from one side to the other side of the bag. At the time of installation, the both sides of the bag body are fused together with both sides of the hand of the bag together, and the inclined fusion section or the inclined adhesion section has the surface of the bag body and the inclined side and is fused or adhered to the surface of the bag body. And a bag having a synthetic resin carrying hand.

[0002]

2. Description of the Related Art Conventionally, a bag made of a synthetic resin is provided with a hole on a side surface of the bag itself so that a hand can be inserted, thereby forming a holding hand. Alternatively, when the side portion of the bag is heat-sealed at the time of bag-making, a synthetic resin-made hand is also heat-sealed together to arrange the bag-hand.

[0003]

In this case, if a bag is first made by providing a hole in the side surface of the bag, the cost can be reduced. However, the capacity of the bag is reduced, and the portion of the hole is reduced. It had a drawback that it was difficult to hold into the hands. In particular, when a heavy object is put into the bag, a force is applied to the periphery of the hole on the side surface of the bag, which not only disturbs the shape of the bag, but also causes the bag to elongate and tear. Instead, use a synthetic resin long tape or long wide tape as a hand on the bag itself, and heat-seal the sides of the film sheets that constitute the bag body during bag making. In some cases, both ends of the tape are fused together with heat fusion of the side portions to form a bag.

In this case, since the hand is made of tape, it is easy and convenient to hold it by hand when holding it by hand, and the weight of the bag is applied to both sides forming the bag, and holes are formed in the side of the bag. The deformation of the bag body can be prevented more than the bag body provided with. On the other hand, if a heavy object is put in the bag, the weight will concentrate on the heat-sealed portion of the side of the tape bag, and this fused portion will peel or tear, causing the bag itself to tear. Had the disadvantage that Therefore, only light-weight items can be put in the bag. For example, when a product with a certain weight or more, such as a plastic bottle or can beer, is put into a synthetic resin bag for sale or transportation, a certain amount or more is used. A synthetic resin bag having high strength was used, and a hole was formed in the side surface of the bag. This has the disadvantage that the cost is not only expensive but also that the peripheral portion of the hole bites into the hand when held by hand, making it extremely difficult to hold. Therefore, some solution has been demanded.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks and prevent the bag from being damaged even when a heavy object is put in the bag, the invention according to the first aspect of the present invention is directed to a handle having a longitudinal shape in the opening direction of the bag.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view showing an embodiment of the present invention for explaining an embodiment of the present invention. The bag 1 is a bag made by thermally fusing a thermoplastic sheet at both sides 1a thereof, and the bottom 1b is formed of a square bottom bag. In the opening 1c of the bag, a hand 2 made of a long tape is provided. This hand 2 has both ends sandwiched between thermoplastic sheets during the thermal fusion of the side 1a of the bag, and is fused simultaneously with the thermal fusion of the side 1a of the bag. is there. In addition, the side portion 1a
The one surface of the bag and the hand 2 are heat-sealed obliquely from the fused portion to the bag opening 1c.

The heat-sealing of this portion is performed by
From the bag body bottom 1b direction to the opening 1c direction of the fusion part with the b part, the fusion is performed obliquely so that the fusion width gradually increases,
It constitutes the inclined fusion part 3 and has the inclined fusion part 3 having the inclined side 3a. With this configuration, when carrying the carrying hand 2 in a state in which a heavy object is put in the bag body 1, the carrying hand 2
Is lifted at both ends along the obliquely fused portion. As a result, the weight in the bag 1 is applied to the entire oblique side 3a of the obliquely fused portion 3 and the weight applied to the fused portion between the hand 2 and the bag 1 is dispersed. The portion is not peeled off, and the force is not directly applied to the fused portion of the side portion 1a of the bag body 1 itself, so that the bag body 1 can be prevented from being torn.
In particular, when only the thermoplastic tape is fused as the hand 8 to the side 7a of the conventional bag 7 when the bag is lifted, the weight of the bag when the bag is lifted is the thermoplastic tape 8 and the bag side 7a.
All of the fused portions are concentrated at one point in the direction toward the inside of the bag 1, and there is a disadvantage that if a heavy object is put into the bag 7, the fusion at this portion is peeled off.

With the construction as in the present invention, the weight of the inside of the bag 1 is reduced by the entirety of the oblique side 3a of the inclined fusion portion 3 in which one surface of the hand 2 and one surface of the bag 1 are inclined and fused. Therefore, no force is applied to the fused portion on the side 1a of the bag body 1. Therefore, even if a heavy object is put in the bag 1, the weight is dispersed, and the inclined fusion portion 3 of the hand 2 is not peeled off at all and the side 1a of the bag 1 itself is fused. There is no peeling at the part. In addition, since the fusion strength of the side portions is increased by the inclined fusion portion 3, the deformation of the bag body 1 itself is prevented. The inclined side 3a of the inclined fusion part 3 is not limited to a substantially linear one, but may be a slightly uneven side or an arc-shaped side. It includes all configurations.

Further, the carrying hand 2 made of a long tape may be narrow or wide, and is not limited to a tape-shaped one and may be a sheet-shaped one having an appropriate width. May be used. As long as the length of the hand 2 is the same as the length of the edge having the opening 1c of the bag 1, the bag can be easily manufactured and the bag 1 can be neatly folded in a folded state. Although it can be stored in the inside, it is not limited to this length and may be longer or shorter. In addition, the inclination angle of the inclined fusion part 3 may be any angle depending on the bag. That is, in the case of a bag having a narrow opening 1c, that is, a vertically long bag, the angle with the side is preferably small, and conversely, a bag having a wide opening 1c, that is, a horizontally long bag. The larger the angle with the side, the better.

For example, as one example, in one substantially square bag, for example, about 45 degrees, in another vertically long bag, about 25 degrees, and in another horizontally long bag. In this case, the angle may be appropriately determined according to the bag body, such as about 60 degrees. Therefore, regarding this angle, the aforementioned 45 degrees,
The number is not limited to a specific number such as 25 degrees and 60 degrees, and may be appropriately determined within a range of, for example, about 10 to 80 degrees or more. With respect to the arrangement of such a hand 2 on the bag 1, the hand 2 is provided between the front and back surfaces of the bag 1 in FIG. 1, but the present invention is not limited to this. The hand 2 may be configured on the outer surface. Alternatively, one end of the handgrip 2 is fused to the front surface which is one surface of the bag 1, and the other end is fused to the back surface which is the other surface of the bag, and each is fused to another surface. It may be.

On the inner surface of one side of the bag body 1 having such a configuration, a film sheet is disposed on both sides of the bag body by heat-sealing together with the side edges of the bag body. The wall 4 is formed along one inner surface. An adhesive member 5 is applied slightly below the upper side of the sheet, and the adhesive surface is covered with a release sheet 6. Therefore, a storage portion can be formed between one inner surface of the bag 1 and the wall portion 4, and the contents can be visually recognized from the outside by sandwiching, for example, a product advertisement or a catalog. In particular, by peeling off the release sheet 6 to expose the adhesive member 5, the space between one inner surface and the wall 4 can be closed in the direction of the opening 1c, so that a product advertisement or catalog sandwiched between the two. And so on.

FIG. 2 is a view showing another embodiment of the present invention. In the opening 1c of the bag 1, two carrying hands 2 made of long tape are provided. This hand 2
Both ends are sandwiched between thermoplastic sheets when the side portions 1a of the bag body 1 are heat-sealed, and are fused simultaneously with the heat-sealing of the side sides of the bag body 1. At the same time, the one hand 2 is formed such that one surface of the bag 1 and the hand 2 are heat-sealed obliquely from the fusion portion of the side portion 1a to the direction of the bag opening 1c to form an inclined fusion portion 3. are doing. Further, the other hand 2 similarly heat-fuses the other surface of the bag 1 and the hand 2 obliquely from the fusion portion of the side portion 1a to the direction of the bag opening 1c to form the inclined fusion portion 3. Make up. Therefore, one hand 2 is provided on each side of the bag 1 by fusing the two sides 1a of the bag 1 with the fusion parts and providing the inclined fusion parts 3. is there.

Also in this case, by holding the hand 2, the weight of the contents of the bag 1 is dispersed and applied to the inclined portions 3 a of the two inclined fusion parts 3 in the direction of both ends of each bag. Even if a heavy object is put into the bag 1, the fused portion 1a of the bag 1 is not peeled off, and the bag can be prevented from being torn or torn. A film sheet is formed on one side of the bag body 1 on the outer surface thereof by heat-sealing on both sides thereof together with the side portions 1a of the bag body 1. A film sheet is provided on the outside to constitute the wall portion 4.
An adhesive member 5 is applied between the film sheet and the surface of the bag 1 slightly below the upper side of the sheet, and the adhesive surface is covered with a release sheet 6. Thereby, it is possible to insert an advertisement or the like between the film sheet and the surface of the bag.

Further, in this figure, two carrying hands are sandwiched between the front and back surfaces of the bag 1, respectively. However, the present invention is not limited to this, and two carrying hands are provided on both outer surfaces of the bag 1. It may be provided. Alternatively, one hand 2 may be sandwiched between the front and back surfaces of the bag 1 and the other hand 2 may be provided on the outer surface of the bag 1. Next, FIG.
Is sandwiched between thermoplastic sheets at the time of thermal fusion, and is fused simultaneously with the thermal fusion of the side portion 1a of the bag 1, and the bag body opening 1c extends from the fusion portion of the side 1a. Both sides of the bag 1 and the hand 2 are heat-sealed obliquely in the direction. The thermal fusion of this portion is performed by oblique fusion so that the fusion width gradually increases from the direction of the bag bottom 1b to the direction of the opening 1c of the fusion portion with the bag side 1a of the carrying hand 2, and the gradient fusion is performed. The wearing part 3 is constituted. A slanted fusion part 3 is formed by fusing with the carrying hand 2 between both surfaces of the bag 1. Even with such a configuration, the weight in the bag body is applied to the inclined side 3a which is the inclined portion of the inclined fusion portion 3.

FIG. 4 is a view showing a state in which the carrying hand 2 of FIG. Therefore, in a normal state, the hand 2 can be held in the bag 1 as described above, and the bag 2 can be taken out of the bag opening when used. FIG.
FIG. 4 is a view showing a state in which a plastic bottle 9 of soft drink, which is a heavy material, is put in the bag body with a handle according to the present invention shown in FIG. Even when a heavy object is put in the bag 1 in this manner, the weight of the contents of the bag 1 on the carrying hand 2 can be reduced by the oblique welding of the inclined fusion portion 3 which is the contact portion with the bag 1. It is located at the boundary, and since the length is more than a certain value, the weight can be dispersed and applied. FIG. 6 is a view showing a state in which a heavy object is put in a conventional bag with a carrying hand, and the carrying hand 8 has both ends at the time of fusing the side 7a for forming the side 7a of the bag 7. Are fused together. Therefore, the weight of the contents in the bag 7 is entirely applied to the fused portion, and most of the weight is applied to a point below the fused portion of the carrying hand 8, that is, at a point in the interior of the bag 7. This can cause tearing and tearing of

Next, the bag making process according to the present invention will be described. First, a sheet constituting the bag 1 is partially folded so as to constitute a square bottom bag and is laid in the direction of the opening 1c of the bag 1. The long tape constituting the hand 2 is sandwiched, and the bag 1
Are fused on both sides 1a. After that, one side or both sides of the bag 1 and the hand 2 are fused to form the inclined fusion part 3. With this configuration, it is possible to extremely easily form the bag with the present invention. In addition, regarding the inclined fusion part 3, in addition to this, for example, after providing the inclined fusion part 3 by fusing the hand 2 on one surface constituting the bag body 1 in advance, the fusion of the both side parts 1a of the bag body 1 is performed. May be performed. Further, for example, in order to provide a wall portion 4 which is a storage portion for accommodating a product description, a label, and the like, a film sheet as the storage portion is formed between the front and back sheets of the bag when the bag is formed. The side part 1a may be fusion-bonded as a whole by sandwiching the sheet or the outside thereof.

Next, the inclined fusion portion of the bag with a handle according to the present invention is not limited to the fusion-bonding portion, and the inclined fusion portion 3 may be formed by, for example, bonding with an adhesive member. For example, the material is not limited to hot melt, and may be any material that uses an adhesive member having a certain degree of adhesive strength. That is, the weight of the contents in the bag 1 is dispersed between the hand 2 and the bag 1, and the connecting portion is inclined so that the weight is applied to the connecting portion. It is only necessary to be able to apply or fuse the inclined portion, which is the continuous portion, exactly.
