JPH068081Y2 - garbage bag - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] This invention is a disposable trash that is stored in a sink when it is washed away of used tea leaves, food residue attached to tableware, etc. Regarding the bag.

[Conventional technology]

Conventionally, as this type of garbage bag,
Some are disclosed in Japanese Patent Publication. Fig. 5 and Fig. 6 show this, which is composed of a tubular net body 21 in which synthetic fiber yarn is knitted in a stocking shape, and the net body 21 requires a long tubular body knitted by a circular knitting machine for stockings. It is made by cutting it to length.

Regarding the shape of the bottom of the garbage bag, it is described that the lower end is tied when using stocking waste, but in the case of commercial products, the lower end opening is folded linearly and sewn with a sewing machine such as an overlock sewing machine. The bag bottom is created by stitching at the eye 22.

[Problems to be solved by the device]

However, in this known garbage bag, it takes a lot of time and effort to form the sewing machine seam 22 for forming the bag bottom, and there are problems that the cost is high due to lack of manpower and the sewing machine seam is easily torn. It was

The present invention has been made in view of such problems of the conventional product, and the problem is that the bag bottom is automatically created on the knitting stage of the tubular net body, that is, on the knitting machine, and is not easily torn. It is to provide a garbage bag with a bag bottom.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, in the present invention, a mouth rubber portion is provided at the upper end periphery of a tubular net body that is open at the top and bottom, and the lower end portion is twisted back around the cylinder center and the net body side surface is provided. This edge was fixed to form a double bag bottom.

[Action]

In the dust bag thus configured, the twisting direction of the outer surface and the twisting direction of the inner surface of the double bag bottom are opposite to each other, and they are squeezed to each other to tightly close the opening. Furthermore, since it has a double bottom, it has a large load resistance and is hard to break, and since it has a rubber band, it can be easily attached to a support.

〔Example〕

As shown in FIGS. 1 to 4, the tubular net body 1 is made by knitting fine and relatively coarse and hard synthetic fiber filament yarns in a circular knitting machine, and has elasticity and upper and lower layers. An opening is provided, and a circular elastic band portion 2 is provided by simultaneously knitting a polyurethane elastic yarn (commonly called spandex yarn) as a splicing yarn at the upper edge of the circular knitting machine when knitting.

Next, the lower end opening edge 3 is turned 360 degrees, that is, a state in which it is twisted by one rotation (see arrow direction A in FIG. 4) and folded back (see arrow direction B in FIG. 4). The lower end opening edge 3 is brought into contact with the side surface of the body 1 and an annular braid 4 is applied to form a double cloth-shaped bag bottom 5 (see FIG. 3).

Since such a garbage bag has large elasticity and is provided with a rubber cuff portion 2, it supports a drainage cylinder inside the garbage reservoir attached to the bottom of the water tank of the sink or a drainage receiver placed on the bottom of the water tank. It is easy to attach to the body and can be attached firmly to a slightly different size support by pulling the lip rubber outward and folding it back.

The double bag bottom 5 has a twist direction of the outer surface 6 (see arrow C in FIG. 2) and a twist direction of the inner surface 7 (see arrow D in FIG. 2) opposite to each other, and the center of the spiral on both sides. It is tightly closed and tightly closed to prevent the stored garbage from flowing out. When this garbage bag is installed inside a support and contains garbage, if the weight of the garbage is applied to the bottom of the bag, the outer and inner surfaces will be strained and the center part will be tightened further and the dust will leak. There is no such thing, and because it has a double cloth bag bottom, there is no hard work to break.

The garbage bag is formed by a circular knitting machine having an electronic patterning mechanism while knitting the tubular net body 1 while the rubber band portion 2 is formed.
And a bag bottom 5 including a twisting operation, a folding operation and a knitting stop 4.
And can be created automatically and efficiently all at once.

The rotation angle at which the lower end is twisted when forming the bag bottom can be appropriately selected according to the type of the netting yarn and the like.

[Effect of device]

In the dust bag according to the present invention, a circular knitting machine is used to create a rubber band while knitting a tubular net body, and at the same time, a double bag bottom is created through twisting operation, folding operation, and edge fixing operation. You can Therefore, labor saving and efficiency can be achieved as compared with the conventional product in which the bag bottom is created by the sewing machine stitch.

In addition, since the double bag bottom is created by twisting the bottom end around the cylinder center and folding it back, if the weight of dust is applied to this bag bottom, the center part will be tightened further and the load bearing capacity will be increased. Excellent in performance. Therefore, unlike the conventional product, since there is no sewing seam, the bottom of the bag is not inadvertently broken, and the dust can be reliably stored.

Further, since only the lower end portion is doubled, water and the like are promptly discharged from the upper single portion.
