Description

[Detailed Description of the Invention] The present invention relates to a garbage bag, particularly a garbage bag made of porous paper and used to store kitchen waste discharged from cooking or the like.

Currently, each household generates a large amount of kitchen waste, and it is difficult to dispose of this waste. Moreover, since these contain a large amount of water, their treatment is even more difficult. These treatments generally use a drainer basket, for example, by placing the basket in the corner of the sink, putting kitchen waste in it, leaving it there for a while, waiting for the water to drain out, and then processing. However, even if you use the above method, the water will not drain completely.
Since this was insufficient, the applicant first developed a "drainer garbage bag" in order to use a garbage bag together with the drainer basket.
(Utility Application No. 55-176026).

The above proposal is as shown in Figure 1.
The bag body 1 is made using paper with good water permeability, and there are holes 2 with some fibers left on the surface of the bag body.
It produces countless amounts of water to help drain the water. Note that the bottom portion 3 and side surfaces 4 are glue allowances, and these portions are glued.

This type of gluing generally involves squeezing out the glue with a needle. However, the squeezing process described above has the disadvantage that the speed is slow, the finished glue width is not properly determined, and when porous paper is used, the glue seeps out onto the outer surface of the paper.

The present invention has been made to solve the above-mentioned drawbacks, and aims to provide a garbage bag with increased manufacturing speed and stability.

In the present invention, the gluing is not done in a solid manner as in the past, but by using a gravure roll to form individual linear units with an inclination, arranged at intervals from each other, and by the linear units. By making the overall shape straight, it is intended to improve manufacturing speed and stability of gluing.

Examples will be described below with reference to the drawings. First of all,
Prior to explaining the examples, the technical background of the study on gluing will be explained.

That is, since squeezing out the glue with a needle during gluing has the above-mentioned drawbacks, it was decided to use a gravure roll. Therefore, a glue groove (cup) corresponding to the glue thickness was formed in the durabiya roll, and the inside of the cup was filled with glue using a vat, scraped off by a coater, and then applied to the paper surface.

Focusing on the viscosity of the glue here, it is desirable to place something with as high a viscosity as possible in the glue groove of the gravure roll, but if the viscosity of the glue is too high, it has the disadvantage that it does not fit properly into the glue groove. If the viscosity of the glue is lowered, not only will it not accumulate at the depth of the glue groove, but it will also
It has the disadvantage that it flows out even if it is attached to paper. Therefore, we considered solving the problem on the gravure roll side by lowering the viscosity to the extent that the glue would accumulate in the glue grooves, and then leaving the low-viscosity glue on the paper surface without flowing out.

What I came up with here was to separate the parts where the glue was attached, and to make them step-like. That is,
After the glued part, I placed the non-adhesive part and then added the glued part. However, it was found that the viscosity was still low and it flowed out. Furthermore, it was found that there was a difference in the degree of flow between vertical lines and horizontal lines depending on the direction in which the paper was moved for gluing. That is, the bottom part 3 in FIG.
rotates with the gravure roll while lying down,
On the other hand, the side surface 4 continues vertically. In this case, the outflow of glue is greater on the side surface 4. Therefore, the idea was to make the shape of the adhesive adhered to be in the form of slanted lines, and to provide space between the slanted lines. In this case, the problem with the bottom part 3 was solved. However, it was found that side 4 still leaked. Therefore, regarding the side surface 4, it was decided to further divide the adhesive attachment position, and the slanted adhesive shape was further divided into two parts at one line interval and separated from each other. The following embodiment has been achieved through the above study results.

FIG. 2 is a partial view showing only the adhesive shape of the garbage bag according to the present invention. In the figure, 5 indicates the glued shape of the bottom portion 3, and 6 indicates the glued shape of the side surface 4. FIG. 3 shows the glued shape on the side surface enlarged, and FIG. 4 shows the glued shape on the bottom enlarged.

In the figure, 5 ₁ and 5 ₂ are the gluing shapes (referred to as linear units) at the bottom, and show the case where the bottom is glued in two rows. and each linear unit 5
₁ are arranged diagonally adjacent to each other with a spacing of 7, and each row is arranged in parallel with a spacing of 8.

Next, numeral ₆₁ is a linear unit arranged at an angle, which is provided every other unit, and linear units ₆₂ and ₆₃ separated from each other with an interval of 9 are arranged between them. And each divided linear unit has an interval of 1
separated by 0.

In addition, although the case where the bottom part is arranged in two rows has been described, this is only a matter of strength, and it goes without saying that the bottom part may be arranged in one row.

As explained above, according to the present invention, gluing is not done in a solid manner, but is separated into linear units by a gravure roll, and each linear unit is arranged at an angle, so that the manufacturing speed is increased. ,
Moreover, an efficient garbage bag can be provided.
