Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to waste disposal bags that can easily dispose of waste materials such as garbage. It is.

0002

[Conventional technology]

For example, on passenger aircraft, waste is placed in each passenger seat after each flight. Waste disposal bags will be distributed, and garbage and other waste generated during the flight will be placed in the disposal bags. At the end of the flight, disposal bags are left at each seat, and cleaning staff collect and dispose of them at the end. There is. The processing bag used at this time is a paper gusset bag. The surface may be coated with a water-resistant coating or covered with a plastic film, e.g. Water resistance is imparted by laminating polyethylene film.

0003 This processing bag has one or more wires near the opening, perpendicular to the open edge of the opening. is equipped with two fasteners. This stopper is several cm long and several mm wide. It consists of a thin strip-shaped metal piece (for example, an aluminum piece), and garbage can be placed in the above-mentioned disposal bag. Then fold the opening of the bag to seal it, and place the above stopper over the folded part. When the bag opening is bent, the shape retention of the metal piece of the stopper prevents the opening of the bag from bending. The container is held in that state and the contents are prevented from coming out (for example, 7-5716).

0004

[Problem that the idea aims to solve]

The waste disposal bags are used as described above, but after the flight, the cleaning staff , only the used disposal bags are collected, and the unused disposal bags are placed on the seats (main seats). To be exact, leave it in the net-like storage compartment attached to the back of the seat in front of you and save it for your next flight. provide Therefore, it is necessary to distinguish between used and unused items, and You can easily tell by looking at the appearance if the item is swollen, but if the item in the bag is slightly swollen. In some cases, it is difficult to distinguish between used and unused items based on their appearance. Therefore, it is clear Sweepers must open all disposal bags and check whether they have been used or not. This makes the work more complicated. In addition, in the conventional processing bags mentioned above, a stopper is attached to the bag, but this is done manually. Therefore, mass production is difficult.

[0005]

[Means to solve the problem]

This invention eliminates the troublesome work of cleaning staff when using the conventional disposal bags mentioned above. We aim to provide waste disposal bags that can reduce waste and further improve the productivity of disposal bags. The porpose is to do. The present invention will be explained in detail below with reference to the attached drawings showing an example of the present invention. Ru.

[0006] Figure 1 is a schematic front view of the processing bag of the present invention, and Figure 2 shows the bag shown in Figure 1 with its upper part folded. Figure 3 shows the upper part of the longitudinal section taken along the line III-III in Figure 2. Schematic cross-sectional view. Figure 4 is a schematic cross-sectional view of the same part as Figure 3, except for the sealing zone at the top end of the processing bag. Figure 5 is a schematic cross-sectional view of the bag of Figure 1 after the area has been removed; FIG. 6 is a schematic perspective view after removing the band;

[0007] In the figure, 1 is the bag body of the bag to be processed according to the present invention, 2 is the opening at the top of the bag body 1, and 3 is the opening. 2 a closure zone at the outer edge of 2; 4 a separation line for separating the closure zone 3; 5 is the first adhesive zone, 6 is the second adhesive zone, and 7 is the fold indicated on the top of the bag body. Barbed wire 8 is a gusset part on the side of the bag body.

[0008] The bag body 1 of the present invention may be a paper bag or a plastic bag, and in the case of a paper bag, the inner surface It is best to make it water resistant by painting it with a waterproof material or laminating a plastic film. stomach. A paper bag is used and its inner surface is coated with a polyethylene layer that acts as a heat-sensitive adhesive. The upside-down version is advantageous because it can be heat-sealed when sealing the opening. It is. When the bag body is made into a gusset type as shown in Figure 5, This is preferred because it accommodates a large amount of waste.

[0009] The outer edge of the bag body 1 on the opening side of the present invention is used as a sealing zone 3 before the bag is used. be locked down. That is, as described above, the inner surface of the bag body 1 is coated with a heat-sensitive adhesive and heated. It may be sealed or sealed with conventional adhesives (pressure sensitive adhesives). bag body At the top of 1, a separation line 4 of the containment zone 3 is provided inside the containment zone 3. It will be done. This separation line 4 is formed by, for example, small holes or short cuts arranged in series at intervals. When you pinch the end of the blockade zone 3 with your fingertips and pull it, the blockade zone 3 can be easily separated.

0010 Inside the tearing line 4 there is a first adhesive zone 5 and a gap between the first adhesive zone 5 and the first adhesive zone 5. A second adhesive zone 6 is provided parallel to the inner side, and is sandwiched between the two zones. A folding line 7 of the bag body 1 is displayed in the center of the area where the bag body 1 is folded. This fold line 7 may be indicated by a solid line or a dotted line, and the bag body 1 should be folded along this line. When the first adhesive zone 5 and the second adhesive zone 6 are attached (the state shown in FIG. 2) They are arranged to overlap (Figure 3).

[0011] Then, one of the first adhesive zone 5 and the second adhesive zone 6 is bonded with an adhesive. layer (pressure-sensitive adhesive layer) and the other layer is a release agent layer (wax, higher fatty acid, silicone). The adhesive strength can be adjusted by adding oil, etc.). That is, the first adhesive zone 5 and When pressing the second adhesive zone together, the adhesive is applied with a weak force and remains as it is. It won't come apart, but if you try to peel it off and pull on one side, it will come off with a slight force. can. In the example shown in FIG. 1, the width of the first adhesive zone 5 is greater than the width of the second adhesive zone 6. However, in such a case, the first adhesive zone 5 is the release agent layer, and the second adhesive zone 6 is the mold release agent layer. becomes the adhesive layer. In other words, if this were the case, the adhesive layer would be more dense than the release agent layer. This is because it protrudes outward, resulting in strong adhesion.

0012 Next, how the above-mentioned processing bag is used will be explained. This bag should be folded according to fold line 7. Fold the top of the bag. In other words, the state shown in Fig. 1 becomes the state shown in Fig. 2, and this folding The cross-section of the bent portion is shown in FIG. are in contact and that state is maintained. Bags made in this way are placed in each seat of a passenger aircraft. Persons who are distributed and use this bag during the flight must use the folded part at the top of the bag body 1. Put it back, pinch the end of the sealing zone 3 of this bag with your fingertips, and pull it. When you do that The blockade zone 3 is easily separated along the separation line 4 and is in the state shown in FIG. becomes.

[0013] Waste such as garbage is put into the bag body 1 through the opening, and then folded again at the fold line 7. When the upper part of the bag is folded at the point, the cross section of the folded part becomes as shown in Figure 4. Thus, the entire width of the bag body 1 is sealed.

[0014] Although the disposal bag of the present invention is used as described above, it is After that, the cleaning staff goes around each seat and removes the seats that have been removed from blockade zone 3. At first glance, you can see that the one with blockade band 3 left intact is unused. Because it is easy to identify, leave unused items for the next flight and recycle only used items. All you have to do is collect it.

[0015]

[Effect of the idea]

(b) Has the disposal bag of this invention been used for waste disposal or has it not been used yet? can be immediately identified at a glance, and, for example, can be distributed to individual passengers on a passenger aircraft and disposed of. It is extremely convenient when used for material processing. (b) As in the past, a separate stopper was attached to seal the bag. The structure is suitable for mass production. (c) The opening is sealed before use, so repeat the unused one and let the user know. There is no sense of uncleanness in offering it.
