Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a bag made of a synthetic resin sheet such as a garbage bag or a packaging bag, and is particularly configured so that it can be closed by tying its mouth and convenient for carrying.

[0002]

[Prior art]

 As shown in Fig. 4, a conventional garbage bag made of synthetic resin sheet is obtained by cutting a tubular synthetic resin sheet 2 into a certain length and sealing one cut end 5 to form a bag 10. There is. When putting the garbage in such a garbage bag 10 and sealing the mouth, a string was wrapped around and tied.

Further, in a packaging bag 11 made of a conventional synthetic resin sheet, a tubular synthetic resin sheet 2 is bent inward at two symmetrical points as shown in the perspective view of FIG. 7) Cut into fixed lengths, as shown in the perspective view of FIG. 5, one cut end 5 is closed to form a bag, and the other cut end 8 is closed, and then cut into a ω shape. , Two rings c for carrying are formed, and two tongue pieces d for connecting and sealing are formed.

[0004]

[Problems to be solved by the device]

 Thus, the conventional garbage bag 10 shown in FIG. 4 requires a string for closing the mouth, and the conventional packaging bag 11 shown in FIG. 5 has two rings c and two tongues. Since the piece is cut into an omega shape to form the piece d, a large amount of waste of the synthetic resin sheet is generated, and a lot of labor and cost are spent for the disposal.

Therefore, the bag made of the synthetic resin sheet of the present invention is conceived in order to solve the problems of the conventional bag.

[0006]

[Means for Solving the Problems]

 In the bag of synthetic resin sheet of the present invention, a tubular synthetic resin sheet 2 is cut into a certain length, one cut end 5 is sealed to form a bag 1, and the other cut end 6 has a longitudinal direction. In addition to forming four perforations 3 on each side, a hole 4 having no corners is formed at the end of each perforation 3.

[0007]

[Embodiment of device]

 As shown in the perspective view of FIG. 1, the bag of the synthetic resin sheet of the present invention is formed by cutting a tubular synthetic resin sheet 2 into a certain length and sealing one cut end 5 to form the bag 1. , The other cut 6 has four perforations 3 formed in the vertical direction from the opening, and the perforations 3 have holes 4 with no corners, such as circular and elliptical. is there.

The perforations 3 and the non-cornered holes 4 are processed by flattening out a tubular synthetic resin sheet 2 to form two overlapping perforations 3 as shown in FIG. A hole 4 having no two corners, which is overlapped with the end portion of the perforation, is formed in the hole. If the two perforations 3 are formed at a distance of ¼ from both ends and the distance is set to ½, the distance between adjacent perforations 3 can be made equal.

When closing the mouth 1 of the bag constructed in this manner, the tongues 3 can be torn to form four tongue pieces a, b, a, b. The tongue pieces a, a and b, b can be easily sealed by tying them in a cross shape.

In addition, when carrying a bag, it suffices to connect adjacent tongue pieces a and b to form a ring. At the end of each perforation 3, there is a hole 4 having no corners. Since it is preliminarily drilled, even if it is forcibly torn, the progress of fracture can be stopped at the portion of the hole 4 having no corner.

(Other Embodiments) As shown in the perspective view of FIG. 6, two symmetrical places are bent inward (7) and cut into a certain length, and then one of the cuts 5 is sealed. Form the bag 1. Then, as shown in FIG. 3, the tubular synthetic resin sheet 2 is spread flat to form two overlapping perforations 3 and two corners overlapping the end of the perforation 3 are formed. Do not drill hole 4.

The position of the two perforations 3 may be set so that the entire circumference of the mouth is divided into quarters.

Note that the intervals between the perforations do not necessarily have to be equal to each other in practical use, and may be set appropriately.

[0014]

[Effect of device]

 As is clear from the above description based on the embodiment of the invention, the bag of the synthetic resin sheet of the invention can easily seal the mouth and easily form a ring convenient for carrying. You can
