  The present invention not only makes the bottom of the garbage bag a round bottom and effectively uses the area of the bottom of the industrial plastic bucket, but also is made of a film that is thinner and stronger than the polyethylene used in conventional garbage bags. Regarding bags.

  Despite the fact that most of the conventional plastic bags have a round bottom, the square bottom sealed in the batch direction has become a classic, so the conventional garbage bag has a bottom surface when the garbage bag is opened. The area could not be used effectively. In addition, they do not fit well with business-use poly buckets, are unsanitary in the treatment of contents such as trash, and have many inconveniences such as trash bags being torn.

  In addition, conventional garbage bags are made from LDPE (Low Density Polyethylene), which has the characteristics of stretching and thinning of the bags. The uneconomical nature that leads to waste was undeniable.

  The trash bag described in Patent Document 1 is a trash bag in which other bags are put in a bag and stacked one after another. Spread the sack while covering it, cover the edges and inside of the trash container, and open the left and right knob holes. Some have been devised to fit into the left and right protrusions of a garbage container.

The garbage bag described in Patent Document 2 is devised to use synthetic resin as a raw material, stack the bags, and provide a seal part at the bottom to effectively use the area of the bottom of a business-use plastic bucket or household garbage box. Yes.

  However, in Patent Document 1, it is proposed that a protrusion is provided on the top of the business-use poly bucket and the bag is locked to the protrusion, but the bottom of the bag remains a square bottom. For example, when heavy trash or other contents are placed, the heavy trash or other contents are concentrated on the narrowed bottom part of the bottom, and the bottom bottom area is also narrowed. It is hard to say that it is effectively used for

  In addition, in Patent Document 2, it has been devised to make effective use of the area of the bottom of the business poly bucket by making the bottom of the garbage bag into a substantially circular shape. Since it is made of polyethylene only, and the polyethylene itself has stretch properties, it must be thick to prevent thinning, leading to wasted oil resources.

  Therefore, the present invention was created to solve the above-mentioned problems, and was made of a mixed resin of LDPE (low density polyethylene) and HDPE (high density polyethylene), which is not found in conventional garbage bag materials. In addition, the purpose is to provide a garbage bag that has a round bottom to make it stable, fits into a business-use poly bucket, and can effectively utilize the area of the bottom of the business-use poly bucket. is there.

  The first means of the invention is to provide a cylinder whose opening is in the shape of a gusset bag, and to form the length of the gusset of the cylinder up to the center of the cylinder width, along the longitudinal direction of the center of the width The cylinder is folded in two through the crease, and four folds are provided along the crease, and a bonded part is formed on the bottom of the cylinder by bonding the folds together to expand the bottom. In some cases, the adhesive portion is developed radially from the center of the bottom portion to form a round circular bottom.

  The second means is that the flat circular bottom portion of the garbage bag is provided in a size that matches the bottom shape of the round-bottom business bucket.

  The third means is to solve the problem by using a mixed resin of LDPE (low density polyethylene) and HDPE (high density polyethylene) as the raw material of the garbage bag.

  According to the configuration of claim 1, a cylindrical body in which the opening portion forms a gusset bag shape is provided, the length of the gusset of the cylindrical body is formed up to the center portion of the width, and the fold portion along the longitudinal direction of the width central portion The bottom of the trash bag by folding the cylinder in half, providing four folds along the crease, and providing an adhesive part at the bottom of the cylinder that is bonded together. Since it becomes a round bottom, the area of the bottom of a garbage bag can be used effectively and more things can be stored.

  According to the configuration of claim 2, the flat circular bottom portion of the garbage bag is provided in a size that matches the bottom shape of the round-bottom business-use poly bucket, so that it is easy to match the business-use poly bucket and the like and is stable in the garbage storage bag. A feeling is born, contents such as garbage can be easily collected at the time of collection, can be easily removed, and can be treated hygienically.
