Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic sheet bag used as a garbage bag or a shopping bag. [0002] Conventionally, when a plastic sheet bag is used as, for example, a garbage bag, the garbage bag is
After packing the garbage in the bag, the mouth is tied and placed in the garbage depot, where it is collected by a garbage truck. At the time of its collection,
The worker grasps the knot of the garbage bag containing the garbage and lifts it.When seeing this garbage bag placed in the garbage storage area, the knot falls down and turns over, It is placed very messyly. In this case, the knot cannot be grasped, so the work must be done by grasping the trunk of the garbage bag.However, heavy, wet, and sharp objects are forced into dangerous work due to heavy labor. I have. In order to solve such a problem, the present inventor has developed a garbage bag that is safe and can be easily carried even if the garbage bag containing the garbage falls down and the knot is lowered. This garbage bag was formed of a plastic sheet, and had a structure in which a sheet piece protruded from the bottom of the garbage bag. [0003] The garbage bag having a sheet piece protruding from the bottom edge of the garbage bag, as described above, has a sheet piece even if the garbage bag falls down and the knot is lowered. Because it comes to the upper side, it can grasp and lift the protruding part of this sheet piece, and even if it is heavy or has a sharp object inside, it has no body by holding both the knot and the sheet piece Therefore, there is a great advantage that work can be performed safely and without difficulty. However, when the garbage bag is normally gripped and transported with a knot, if the protruding portion of the sheet piece is long, the garbage bag may hang down and drag, resulting in a poor appearance. It is also conceivable that the user steps on the vehicle. In addition, for the poor appearance by dragging the above-mentioned sheet pieces and the problem of stepping, in a manufacturing method in which a long sheet material is continuously formed by cutting the long sheet material, it is possible to simultaneously form only a short sheet piece. The hand strap will also be shortened, and for example, it will not be possible to lock the hand strap to the ear of a garbage can. The present invention has been made in view of these problems. As described above, when the garbage bag containing the garbage falls down and the knot is lowered, or the garbage bag is heavy or sharp inside, Even if things are included, it is not necessary to hold the torso, leaving the advantage of being able to work safely and reasonably, without impairing the appearance when carrying,
It is an object of the present invention to provide a safer garbage bag that is safer and can have a wide opening without being trampled. [0005] In order to solve the above-mentioned problems, in the plastic sheet bag of the present invention , gussets are provided on both side edges.

The upper edge of the opening provided between the handbags,
The structure is provided from the lateral position avoiding the gusset to the bottom edge . The plastic sheet bag of the present invention is provided with a sheet piece protruding from the bottom edge of the bag body and a cut line extending a hand portion protruding upward from the opening. Therefore, when used as a garbage bag, even if the garbage bag containing the garbage is turned upside down with the knot down, a sheet piece is protruded from the bottom edge that faces upward. The protrusion can be carried as a clue. In addition, the handle part protruding from the opening and the cut line extending the hand part allow the opening part to be wider than usual even if the hand part is short, for example, the hand part on the ear of a garbage can. If it is used by hanging it, the garbage bag can be prevented from shifting, and the garbage can be easily tied even when the garbage is discharged because the lengths of the hand-held portions at both ends have a margin. FIG. 1 is a front view showing a plastic sheet bag according to an embodiment. 2, 3, and 4 are perspective views illustrating a use state of the embodiment. As shown in FIG. 1, the plastic sheet bag 1 is a plastic sheet having gussets 2 formed on both sides, and a bag body 1a is formed by upper and lower heat welding portions 3. In order to provide the opening 4 at the upper edge of the bag body 1a, short hand-held portions 6 are formed at both left and right ends of the bag body 1a,
The inside is cut out by a cutout 5. The notch 5 is formed inside the handle 6 so that U-shaped notches 5a cut into a substantially U-shape so as to cover the gussets 2 are connected to each other in a gentle arc. Since the handle portion 6 is cut out so as to cover the gusset portion 2, it is opened in the horizontal direction, and, for example, it is easy to pass through the arm or to lock it to a projection. A cut line 7 is provided at the bottom 5b of the U-shaped notch 5a for extending the hand-held portion. A cut hole 7a is opened at the end of the cut line 7 at the end. Further, a short sheet piece 9 having the same shape as the cutout portion 5 formed on the opening side from the thermally welded bottom edge protrudes from the bottom edge portion 8. As an example of using the garbage bag 1 of this embodiment, as shown in FIG. 2, first, the left and right end portions of the hand-held portion 6 are respectively outwardly opened to cut the broken broken line 7.
Then, as shown in FIG. 3, the garbage can 20 is put into the garbage can 20 with the opening 4 facing upward, and the handhold portion 6 is attached to the garbage can ear 20a.
And dust is introduced from the opening 4. When the garbage is collected, the garbage is taken out of the garbage can, the both hand parts are tied and the opening is closed, and the knot 6a formed at this time is held as a clue and taken out to a predetermined place. Reference numeral 21 in FIG. 3 denotes a lid of a garbage can. [0010] As shown in FIG.
Even when the garbage bag is turned upside down and the knot 6a is down, the garbage bag 1 of the present embodiment is provided with the sheet piece 9 protruding from the bottom edge. Can have. In particular, when it is heavy or wet and it is very difficult to hold, or when there is a sharp object in the invisible type garbage bag, you can hold the knot and the sheet piece 9 with both hands. , Safe and easy to transport. Also, as described above, the opening has a broken dashed line 7.
By cutting it and widening the opening, even a small garbage bag with a short handbag can easily be put on the ears of a garbage can, improving usability. In addition, even when the cut dashed line 7 is cut open, a notch hole 7 is provided at the end point of the cut dashed line 7.
Since there is a, there is no breakage more than necessary. The garbage bag 1 is separated from the rolled continuous garbage bag 1C shown in FIG. 5C by a broken line 8, and the manufacturing process of the rolled garbage bag 1C will be described below with reference to FIG. explain. First, as shown in FIG. 5A, a continuous cylindrical plastic sheet 1A having gussets 2 formed on both sides is formed. Next, the continuous tubular plastic sheet 1
In FIG. 5A, as shown in FIG. 5 (b), two heat-welded portions 3 arranged close to each other are formed at regular intervals, and at the same time, a cutting broken line 10 for cutting is formed between the two heat-welded portions 3. It is formed. The cut dashed line is provided so as to form both ends 10a and the notch 5 continuously to both ends 10a. Then, a cut broken line 7 cut from the portion forming the bottom 5b of the U-shaped cutout portion of the cut broken line in the bottom edge direction, and a cut hole 7a is formed at the end point. Thereby, as shown in FIG. 1, a sheet piece 9 is formed on the bottom edge of the bag body 1a,
The garbage bag 1 having the opening 4 formed in the center of the upper edge and the handholds 6 formed on both sides of the upper edge is cut by a broken line 10.
To form a continuous garbage bag continuous sheet 1B. Next, the garbage bag continuous sheet 1B is wound up in a roll shape to form a roll-shaped continuous garbage bag 1C as shown in FIG. In addition, the garbage bag continuous sheet 1B has an outer portion folded inward along the longitudinal direction thereof, and is folded in three, and is wound in this three-folded state. Note that the number of folds is arbitrary.
It can be set appropriately such as folding. As described above, the garbage bag 1 of the present embodiment is formed into a continuous garbage bag continuous sheet 1B by the broken broken line 10, and the garbage bag continuous sheet 1B is wound into a roll. 1C. Therefore, if one garbage bag 1 is fed from the roll-shaped continuous garbage bag 1C and cut off from the broken broken line 10, the garbage bag 1 shown in FIG. 1 can be obtained, thereby improving the usability. Also, at the time of manufacture, since the opening 4 and the sheet piece 9 are formed at the same time by the cutting broken line 10,
Its manufacture is simplified. Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment. For example, the size and shape of the sheet piece 9 are not particularly limited, but are formed so that they can be used as clues for carrying. Further, a mark, coloring, or the like may be provided so that the sheet pieces 9 are easily conspicuous, two or more sheet pieces may be formed on the bottom edge of the bag body, or one sheet piece may be provided. Further, holes for finger hanging can be formed in the sheet piece 9. As the material of the plastic sheet, polyethylene resin, polypropylene resin, and other thermoplastic resins can be used. Further, in the embodiment, the case where the plastic sheet bag is a garbage bag has been described, but it may be a shopping bag or another storage bag. Further, the number and position of the cut dashed lines 7 are not limited, and can be arbitrarily set if there is an effect of extending the handle portion 6. For example, it may be symmetrical as shown in FIG. 6, or may be asymmetrically provided as shown in FIG. Alternatively, only one location may be used, and a cut line that does not need to be broken may be used instead of a broken line from the beginning. In this embodiment, an example has been described in which the rolls are continuously formed and used one by one at the time of use. However, they may be separated and manufactured one by one and used in a bundle. As described above, in the plastic sheet bag according to the present invention, since the sheet piece is protruded from the bottom edge of the bag body short enough to be gripped by hand, The sheet piece can be used as a clue for carrying. Therefore, for example, in the case of a garbage bag, when carrying a garbage storage garbage bag from home to a garbage storage place, or when loading the garbage storage garbage from the garbage storage place into a garbage collection vehicle, an unnecessary portion is dragged without deteriorating the appearance. In addition, it is possible to carry the portable device safely and easily without having to step on the edge of the garbage bag. Also, since a vertical cut line was provided on the opening side,
By breaking this cut dashed line and opening outward, the opening can be widened, and the handle can be made longer so that it can be easily tied when closing the garbage bag, and can be easily hooked on the ears of the garbage can. The effect of preventing slippage is also obtained.
