Abstract

(57) [Summary] PROBLEM TO BE SOLVED: To easily and surely close a bag mouth without using a string or a rubber band after storing garbage. SOLUTION: The garbage bag of the present invention melts a polyethylene tubular film obtained by an inflation molding method perpendicularly to the flow direction of the tubular film to form a bottom 11, The bag opening 12 is similarly cut at a suitable distance from the bottom in the flow direction and cut in the vertical direction. At a position slightly lower than the bag mouth 12, a perforation 13 is inserted from the side parallel to the bag mouth.

[Technical field to which the invention belongs]

 This invention relates to a plastic film garbage bag used in a home kitchen or office.

[0002]

[Prior art]

 A garbage bag made of plastic film used in a home kitchen, office, or the like, is a method in which a tubular film obtained by an inflation molding method is applied in a direction perpendicular to the flow direction (MD) of the tubular film. The bottom and the bag mouth are formed by fusing or cutting, and usually those having dimensions of about 300 to 1500 mm in length, 200 to 1000 mm in width, and about 8 to 100 μm in film thickness are used.

[0003] Such a garbage bag prevents odors from coming out of the stored garbage, prevents the garbage from scattering and scattering, and furthermore, makes it easier to hold the bag when the garbage is discharged. In addition, the bag mouth was closed by crossing and tying both sides of the bag mouth, by pursuing the bag mouth and tying it with a string, and by attaching rubber infusion. However, if both sides of the bag mouth of the garbage bag were tied together, there was a problem that the central portion of the bag mouth was easily opened <, and the odor of the garbage leaked out from there. -When the bag mouth is tied with a string or a rubber band is attached, a string of a suitable length or rubber transfer must be prepared separately from the garbage bag. It was troublesome.

[0004]

[Problems to be solved by the invention]

 An object of the present invention is to provide a user-friendly garbage bag in which a bag mouth can be closed easily and securely without using a string or a rubber band after storing the garbage.

[0005]

[Means for Solving the Problems]

 The garbage bag of this invention is provided with a bottom at the lower end of a cylindrical plastic film. A perforation is made near the upper edge in parallel with this, and when the film is cut along the perforation, the garbage is removed. A string connected to the bag is obtained, and this bag is used to bind the bag opening of the garbage bag.

[0006] The material of the garbage bag includes low-density polyethylene, linear low-density polyethylene, high-density polyethylene, polybutene pyrene, polyvinyl chloride, ethylene-vinyl acetate copolymer, polyethylene terephthalate. And thermoplastic resins such as polyvinyl alcohol. Further, the above two or more kinds of materials may have a laminated structure or may be used by blending. Further, a garbage bag may be made translucent or opaque by adding a pigment or an inorganic filler. Further, an adsorbent such as zeolite or a mixture of ascorbic acid and iron carbonyl is added in an amount of 0.5 to 10% by weight of the film component, or a solid weak acid such as counic acid, tartaric acid or ascorbic acid is added in 0.1%. Up to 5% by weight may be added to further improve the adsorption power of odors such as ammonia. In order to suppress the generation of static electricity and facilitate opening of the bag, an antiblocking agent such as silicon oxide or talc may be contained in an amount of 0.05 to 2% by weight. Further, the garbage bag may be stretched again to increase its strength.

The perforation position is preferably 10 to 100 mm below the upper edge (bag opening) of the bag. If it is less than 10 mm, the strength of the string formed by cutting and perforating the perforations will be weak. On the other hand, if it exceeds 100 mm, it will be difficult to wind the bag mouth with this string. The length of the string formed by tearing the perforation differs depending on the size of the garbage bag, but it is necessary that the length be small enough to be wound around the bag mouth and tied. For that purpose, a range of about 50 to 300 mm is preferable. The garbage bag is easily melted or crystallized in the direction of flow of the cylindrical film, so it is easy to tear in the longitudinal direction. Is actually difficult, and it is preferable to make perforations of the required length from the beginning. The perforations may be formed at the same time as the bag film is formed by cutting the cylindrical film with a force cutter die, or may be formed later.

The garbage bag containing the garbage is cut along the perforations to form a string, and the string is wrapped around a pursed bag opening and tied. This allows the garbage bag to be carried as it is while the bag mouth is securely closed. Therefore, as in the past, the bag mouth is in an open state and the odor of garbage does not leak from it. <It is clean and sanitary, and there is no need for a string or rubber rubber to close the bag mouth. Therefore, handling is easy.

Since the end of the string obtained by cutting the perforation is connected to the garbage bag main body, even if the string is repeatedly untied or tied every time garbage is added, the string does not exist. It's convenient because it doesn't fall.

[0010] By the way, in the present invention, the perforations are inserted in parallel with the bag mouth, but it is also conceivable to insert them at right angles to the bag mouth. Japanese Unexamined Patent Publication No. Hei 8-188202 describes a garbage bag in which a perforation is vertically cut from a bag opening of a garbage bag. It is tied up. However, since the length of the string needs to be about 20 cm, this method has a disadvantage that the effective depth of the garbage bag is reduced accordingly. On the other hand, in this invention, the perforation is parallel to the bag mouth, and even if the bag is cut along the perforation, the amount of garbage that can be stored is almost Does not decrease.

[0011] If necessary, a notch connected to a perforation may be provided on a side edge of the garbage bag. In this case, the perforation can be easily torn using the notch as a starting point.

[0012]

[Embodiment of the invention]

The garbage bag of the present invention shown in FIG. 1 is obtained by cutting a polyethylene tubular film obtained by an inflation molding method in a direction perpendicular to the flow direction of the tubular film and heat-sealing it. A bottom 11 is formed, and a bag opening 12 is formed by cutting the bottom 11 at a suitable distance in the flow direction from the bottom in the same manner as above. The size of the garbage bag is 80 cm long and 65 cm wide when spread on a flat surface.

In this garbage bag, a perforation 13 is inserted into the bag mouth from the side at a position approximately 5 cm below the bag mouth 12. For perforation, insert the two films on top and bottom at the same time. The perforation length is about 20 cm (the total of the perforations on the front and back films is about 40 cm).

As shown in FIG. 2, the garbage bag 1 is used in such a manner that a portion above the perforation 13 is gripped, the film is torn along the perforation, and a string 14 connected to the garbage bag is formed.

Next, as shown in FIG. 3 (A), the bag mouth is narrowed, the outer periphery thereof is wound around with a cord 14, and as shown in FIG. 3 (B), the leading end and the base end of the cord are tied. Match. With this, the mouth of the garbage bag is sealed, so that the unpleasant odor generated by the stored garbage does not leak out. The garbage bag can be safely stored indoors. In addition, the bag mouth tied with a string can be easily carried by hand.
