Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage bag for storing kitchen waste and the like.

Garbage bags are usually stuffed with garbage such as kitchen waste and then disposed of by closing the opening. However, since the opening edge of a conventional garbage bag is straight, the opening is tied with a string or a rubber band, and opposing positions of the opening edge are tied together to close the bag.

As a result, the volume of garbage in the garbage bag becomes small, making it impossible to store a large amount of garbage. Moreover, it takes time and effort to close the opening, and it is difficult to lower the clogged garbage bag. There are drawbacks.

The purpose of the present invention is to solve the above-mentioned drawbacks, to eliminate any material loss during manufacturing as with conventional garbage bags, to be able to manufacture efficiently, and to easily close the opening. We provide garbage bags with a large storage capacity.

To achieve this objective, the present invention involves cutting a flat cylindrical film whose ends are closed by heat welding into a wavy shape with alternating peaks and valleys, and using the cut edges for binding. It has a structure in which a protruding piece is formed.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 3, the openings at both ends of the cylindrical film 10 made of a synthetic resin film such as nylon or polyethylene are as follows.
It is closed by forming a linear heat welded part 11.

The cylindrical film 10 is cut into three equal parts in the longitudinal direction into a waveform shape in which peaks and valleys are alternately continuous.

The shape of the above-mentioned cutting line is arbitrary. For example, if the cutting line 12 is made up of three chevron lines and two valley lines that are alternately continuous, as shown by the chain line in FIG. The waste packaging bodies 1, 1 as shown in the figure can be formed at the same time. A pair of protrusions 2 are attached to the opening edges of these garbage container bodies 1, 1.
, 2 are formed, and when the opposing protrusions 2 are tied together, the opening of the waste container body 1 can be closed, as shown in FIGS. 4 and 5.

As shown in FIG.
When the opening edge of the garbage container 20 is folded back to the outside of the garbage can 20, the opening of the garbage container main body 1 is held in a circular open state, making it easy to put garbage inside. Since the protruding pieces 2 hang down on the outside, the protruding pieces 2 can be easily tied together.

In addition, there is no inconvenience that the protrusions are soiled by the garbage put inside the waste container main body 1, and as a result, the protrusions 2 can be tied together without getting your hands dirty, and by tying the protrusions 2 together, you can This makes it easier to take out the waste packaging main body 1 from the waste bin 20.

Now, a flat blown film is sent towards a pair of linear hot plates arranged in parallel with a required interval, and when the hot plates are lowered after the film stops, the films are thermally welded. By cutting the film along the hot-melt neck at the rear of the leek film in the transport direction, the third
A cylindrical film 10 as shown in the figure can be formed. In the forming apparatus for such a cylindrical film 10,
A cutter with a wave-shaped cutting edge is disposed between a pair of hot plates, and by lowering this cutter immediately after the hot plates are lowered, the cylindrical film 10 is simultaneously formed and removed from the cylindrical film 10 as shown in FIG. Also, two garbage packaging bodies 1 as shown in FIG. 2 can be easily formed.

As described above, in the present invention, a cylindrical film whose both ends are closed by heat welding is cut into three equal parts in the length direction into a wavy shape in which peaks and troughs continue alternately. It is possible to simultaneously form two garbage packaging bodies with pieces, and there is no loss of material, resulting in a great effect on the effective use of materials.

In addition, by connecting the projecting pieces of the waste container body to each other, the opening edge of the waste container main body can be easily closed.
Compared to conventional garbage bags with straight opening edges, this allows for a larger space for storing garbage.

Furthermore, by tying the projecting pieces together, it becomes easier to handle and transport when discarded.

In addition, since the manufacturing method shown in the examples can be adopted, the garbage bag can be easily manufactured.
