[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a trash bag in a case used as a trash bag for business or household use.

[0002]

[Prior Art]

 Conventionally, the following is known as a garbage bag housed in a case. That is, as shown in FIG. 13, one end edge (right side in the drawing) of the inflation film 12 in the length direction (left and right direction in the drawing) is cut, and the other end edge is heat-welded to form a welded portion 12a. Then, the dust bag 11 is formed by being cut on the outside thereof.

That is, as shown in FIG. 15, one end edge in the length direction is in an open state, and the other end edge is provided with a welded portion 12 a and is in a sealed state. Further, as shown in FIG. 16, both sides in the width direction are integrally formed. Then, as shown in FIG. 13, the dust bag 11 thus produced is folded in four in the width direction. As shown in FIG. 14, this rubber bag 11 is folded in two in the width direction at the portion indicated by the chain double-dashed line in FIG.

Then, as shown in FIG. 11, the dust bags 11 are accommodated in a rectangular box-shaped case 13 in a vertically stacked state. As shown in FIG. 12, an outlet port 14 is opened at one end of the upper portion of the case 13. Then, the garbage bags 11 can be taken out one by one from the take-out port 14 and used.

[0005]

[Problems to be solved by the device]

 However, as shown in FIG. 11, the conventional garbage bag 11 is folded in two inside the case 13 and is housed in a vertically stacked state. Therefore, the garbage bag 11 is taken out from the outlet 14 of the case 13. At this time, as shown by the chain double-dashed line in the figure, the weight of the dust bag 11 is added to the portion of the dust bag 11 that is taken out and located in the lower part of the case 13. Therefore, there is a problem that it is difficult to remove the dust bag 11 from the case 13. In addition, since the dust bag 11 is folded in two and housed in the case 13, the case 13 becomes long in the length direction, and there is a problem that a space for placing the case 13 is required accordingly. It was

Further, since the dust bag 11 is cut at one end in the length direction and sealed at the other end, it is folded in half in the width direction and housed in the case 13, so that it can be used. When the trash bag 11 is opened by opening the trash bag 11 as shown in FIG. 17, the welding portion 12a at the bottom of the trash bag 11 becomes a straight line, which makes it uncomfortable to sit and There was a problem that the load was applied only to the linear seal part and the strength was low.

The present invention has been made to solve the above problems, and the purpose thereof is to easily remove a dust bag in a case and to adjust the space for storing the case. , When the garbage is put in the garbage bag, the bottom part expands so that it is comfortable to sit in, and it is to provide a strong garbage bag in a case.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, the inflation film is folded into a plurality of pieces along the length direction, and in that state, one end edge in the length direction is cut and the other end edge is sealed and cut into a garbage bag. The gist is a case-shaped waste bag that is housed in a box-shaped case that has an opening formed in the top and has a take-out opening that opens in the upper part, and is housed in a vertically stacked manner so that it does not weigh and does not have its own weight.

[0009]

[Action]

 The garbage bags are stacked vertically so that they meander in the case and do not apply their own weight.Therefore, when removing the garbage bags from the outlets on the top of the case, the garbage bags are loaded in order from top to bottom. Since it can be taken out, it is easy to take out the dust bag from the case. Further, since the garbage bag is stored in the case in a folded state, the shape of the case can be adjusted and the case can be shaped according to the storage location.

Furthermore, since one edge of the garbage bag is cut and the other edge is sealed in the folded state, when the garbage bag is opened during use, its bottom is flat and comfortable to sit on. At the same time, wrinkles are formed that extend radially around the center of the bottom surface, thus improving the strength of the bottom.

【Example】

 One embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIG. 1, the case-containing dust bag 1 of this embodiment is made of polyethylene with a thickness of 0.02 mm, and is stacked in a rectangular parallelepiped case 2 in a meandering direction in the left-right direction in the figure. It is housed. Since the garbage bag 1 is housed in a meandering state, three ridges are formed in the upper part and both ends thereof are in the lower position. Then, as shown in FIG. 2, the dust bag 1 is easily picked out from the take-out port 3 which is opened at the ridge of the case 2. It should be noted that about 100 garbage bags 1 for business use and about 30 household bags are housed in the case 2, and usually 10 to 100 garbage bags are housed in the case 2.

As shown in FIG. 3, the material for forming each of the dust bags 1 is inflation-molded, and the inflation film 4 which is tubular when opened is a long (folding diameter) 900 mm long piece. It is formed into a shape. In this state, the inflation film 4 is in an open state in the length direction (left and right direction in the figure). From this state, the inflation film 4 is folded into four along its length, and has a width of ¼, that is, 225 mm, as shown in FIG. This step is usually performed immediately after winding the inflation film 4 and immediately before winding.

Then, as shown in FIG. 5, in this state, one end edge in the length direction of the inflation film 4 is cut, and the other end edge is heated and welded at a position with a length of 1000 mm to form a welded portion 4a. Is formed and is cut outside the welded portion 4a. In this step, since the width of the inflation film 4 is 1/4 of the width of the original inflation film 4, it is possible to perform the bag-making operation with a plurality of, for example, four inflation films 4 arranged side by side. In this way, each garbage bag 1 is obtained.

Next, the operation and effect of using the case-containing dust bag configured as described above will be described. As shown in FIG. 1, when the dust bag 1 is taken out from the case 2, the dust bag 1 at the uppermost position among the dust bags 1 stacked from the take-out port 3 of the case 2 as shown by the chain double-dashed line in FIG. Grab and pull out. Then, both ends of the dust bag 1 move toward the outlet 3 side of the case 2. At this time, the garbage bags 1 are vertically stacked and folded so that the garbage bags 1 meander in the case 2 and do not receive their own weight, so that the respective garbage bags 1 can be easily pulled out sequentially.

Further, as described above, since the dust bag 1 is accommodated in the case 2 in a state where it is folded in plural so as to meander, it is folded in half and accommodated in the case 2 as in the conventional case. Unlike the above, the case 2 becomes compact and the space for storing the case 2 in the garbage bag 1 can be saved. Next, when dust is put into the dust bag 1 taken out from the case 2, as shown in FIG. 6, the dust bag 1 has a bottomed cylindrical shape, and its bottom portion is flat. Therefore, compared with the conventional bottom portion of the garbage bag 1 which is formed in a straight line, the garbage bag 1 can sit comfortably in a state where the garbage bag 1 is housed and is convenient for storage.

Moreover, a plurality of wrinkles 5 extending radially are formed at the center of the bottom of the dust bag 1 so as to overlap each other. This is because when the dust bag 1 is formed, it is previously folded into four and the other edges are heat-welded to form the welded portion 4a. That is, when dust is put into the dust bag 1 and inflated in this state, the bottom portion thereof spreads in a twisted form, and the wrinkles 5 extending radially from the center portion are formed. As a result, the strength of the wrinkle portion 5 is increased, and the strength of the bottom portion of the dust bag 1 is greatly improved as compared with the conventional one.

Furthermore, after the inflation film 4 is inflation-molded, it is folded into four pieces in the length direction and then made into bags. Therefore, it is possible to carry out a bag-making operation with a plurality of inflation films 4 arranged in parallel. Therefore, the bag manufacturing efficiency is improved, and the manufacturing cost can be reduced. The present invention is not limited to the above-described embodiments, and may be configured as follows, for example, within the scope of the invention. (1) As shown in FIG. 7, the number of peaks in the upper portion of the dust bag 1 in the case 2 may be two. In this case, as shown in FIG. 8, the length of the case 2 in the up-down direction becomes long, but the depth in the front-rear direction becomes short, which is suitable when the case 2 is stored in a place having a narrow depth. .. (2) As shown in FIGS. 9 and 10, the state in which the dust bag 1 is housed in the case 2 is formed in the same manner as in the above-mentioned embodiment, and the elongated hole-shaped outlet 3 is provided at the center of the upper surface of the case 2. Good. In this case, the dust bag 1 in the case 2 is taken out by grasping the mountain located at the center. (3) The folding of the inflation film 4 in the length direction is four in the above embodiment, but it may be two or more, three, five, or the like.
