Description

  The present invention relates to a bag.

  When a bag is used as a packaging material, it is required that the manufacturing cost is low, the strength is high, the lifting is convenient, and the bag is clean. In addition, when the bag is used for storing a packaging object, it is required that the bag does not pollute the environment at the time of disposal and has a small volume and can be stored in a space-saving manner. In a supermarket where a vinyl bag is not used, it is common to use a flat-mouth bag to accommodate a packaging object. However, since a normal flat bag has no handle portion, it cannot be easily lifted.

  Please refer to FIG. 1 and FIG. Since the conventional flat bag 1a is easy to manufacture, the manufacturing cost can be greatly reduced. However, when used, the bag opening 2a is generally folded and the bag opening 2a is gripped by hand. However, when a heavier item is accommodated, it is necessary to fold the folding corners 21a at both ends of the bag opening 2a because the supporting force is insufficient only by folding the bag opening 2a.

  Please refer to FIG. In order to facilitate lifting of the bag, the conventional flat bag 1b is provided with a handle 4b in the vicinity of the bag opening 2b and is made of resin or paper. However, when the flat bag 1b is made of resin, the resin at the upper edge of the handle 4b is elongated and thinned when a heavy package object is stored in the flat bag 1b due to the elasticity of the resin. The mouth bag 1b is deformed and becomes difficult to store, and the flat mouth bag 1b is difficult to use again. When the flat bag 1b is made of paper, the handle 4b is provided so that the strength in the vicinity of the bag opening 2a cannot be maintained. It may be torn from 4b.

  Please refer to FIG. A conventional flat-mouth bag 1c has a rope 3c at the approximate center of the bag opening 2c fixed thereto. If it does so, since manufacturing work will become complicated, manufacturing cost will increase, and since the total weight of the packaging object accommodated in the flat-mouth bag 1c will be applied to the connection location of the bag opening 2c and the rope 3c, the bag opening 2c It becomes easy to tear. Further, when the flat mouth bag 1c provided with the rope 3c is stored or transported, the bag opening 2c is creased or the like by the rope 3c, so that the overall appearance is deteriorated.

  Please refer to FIG. The conventional flat bag 1d has a handle 4d in the vicinity of the bag opening 2d. A reinforcing sheet 41d is provided on the handle 4d in order to increase the strength of the handle 4d. However, when the reinforcing sheet 41d is provided on the handle 4d, the manufacturing operation becomes complicated and the manufacturing cost increases. Further, when a material that is not naturally decomposed is used for the reinforcing sheet 41d, the environment may be contaminated during disposal.

  The main object of the present invention is to provide a bag that is convenient, can reduce the manufacturing cost, can be stored in a small space, and has a strength as a whole.
