[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a garbage bag and a continuous body thereof. In particular, it relates to a garbage bag and its continuum that can be easily closed.

[0002]

[Prior art]

 When closing the opening of the garbage bag, it is general to use another closure such as a string, or to tie the ends of the opening in a string shape, or to tie the openings together and tie them in a node shape. The method of tying the opening is simpler than the method of using another closure, but since the opening of the conventional garbage bag is straight, it is difficult to tie it and it can be solved even if tied overnight. It was easy.

In some cases, after sealing the upper side of the bag, the upper part of the bag is cut into a U-shape or W-shape, and the cross-sections on both sides are used as a handle, which is the same shape as a so-called “register bag”. Garbage bags are used. With such a garbage bag, it is easy to tie the opening when using the handle part, but such a closing method does not have a sufficient function to close the bag, and the contents may spill if the bag falls. was there.

[0004]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to provide a trash bag and a continuous trash bag body that can easily and surely close the opening.

[0005]

[Means for Solving the Problems]

 As means for solving the above problems, there is provided a dust bag 1 having four protrusions 2 in an opening 4, and a seal portion 5 and a perforation 8 are provided at regular intervals. The flattened tubular film 7 is provided, and the perforations 8 are substantially W-shaped, and the tubular film 7 is cut by the perforations 8 so that the opening 4 and the projection 2 of the dust bag 1 are formed. A continuous waste bag body 9 characterized by being formed is provided, and furthermore, a flattened tubular film 7 having gusset portions 3 on both sides and having seal portions 5 and perforations 8 provided at regular intervals. The continuous perforation bag is characterized in that the perforation 8 is substantially concave, and the opening 4 and the protrusion 2 of the dust bag 1 are formed by cutting the tubular film 7 with the perforation 8. 9 is provided.

That is, in the case of tying and closing the opening portion of the bag, attention is paid to the fact that the closing function is remarkably improved when the bag is tied twice in a taxi shape as compared with the case of tying it once. We propose a garbage bag with four protrusions.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a garbage bag 1 according to the present invention. Like the commonly used garbage bags, the garbage bag 1 is preferably made of a thermoplastic resin from the viewpoint of productivity, and particularly when a polyethylene resin is used, the garbage bag 1 can be manufactured at low cost. It is preferable because it can be manufactured. Further, in order to reduce the calories burned in the garbage bag, it is possible to mix calcium carbonate or to add various other additives.

The garbage bag 1 according to the present invention has four protrusions 2 in the opening. These protrusions 2 ensure that the garbage bag is closed by tying the two of the four protrusions 2 that face each other first when trash is thrown, and then tying the remaining two in the same way. And prevent the dust from leaking when the dust bag falls. The shape of the protrusion 2 is not particularly limited, and various shapes can be adopted as shown in FIG. However, if the protruding length is too short, it will hinder the knotting, and if it is too long, it will be an obstacle, so it is preferable that the length is about 7 cm to 25 cm depending on the size and material of the bag. . Further, when the garbage bag 1 has the gusset portion 3 on the side surface, the width of the garbage bag 1 is narrow for the capacity, and the storage space is not required.

FIG. 2 is a plan view showing an embodiment of the continuous dust bag 9 according to the present invention. The continuous trash bag body bag refers to a series of trash bags that are not separated into individual trash bags, but can be obtained by cutting them at a perforation line immediately before use. . Pre-cut garbage bags can be messy or lost during storage, but continuous garbage bags are easy to manage without such concerns. Further, the continuous garbage bag may be rolled or folded from the end for easier handling, and may be put in a case such as a paper box if necessary.

In the continuous dust bag 9 of the present invention, the tubular film 7 has the seal portion 5 and the perforation 8 at regular intervals, and when the film is cut at the perforation 8, the seal portion 5 is used. As a result, a dust bag 1 having a bottom and an opening and four protrusions 2 formed by perforations 8 is obtained. Therefore, the seal portion 5 is provided from one side end of the tubular film 7 to the other side end. Further, as the shape of the perforation 8 capable of forming the four protrusions 2 in the opening 4, two shapes, that is, a substantially W shape and a substantially concave shape are proposed. When the sealing portion 5 and the perforations 8 are provided in a state where the tubular film 7 is simply folded flat, the perforations 8 may be formed in a substantially W shape as shown in FIG. 2 (A).

However, in order to increase the capacity of the dust bag 1 without widening the width of the continuous dust bag 1, the continuous dust bag 1 has a gusset 3 on the side surface. If the four protrusions 2 are provided with the letter-shaped perforations 8, the widths of the protrusions 2 formed on both sides may become too wide, and it may be difficult to tie them. Therefore, when the continuous dust bag 9 has the gusset portion 3, we propose a substantially perforated shape shown in FIG. 2- (B) as a preferable shape of the perforation 8. The perforations 8 are located at the side ends of the tubular film and are parallel to each other at two points a and a ', and the distance from the seal portion 5 is greater than a and a', and the gazette is still present. It passes through two points b and b ′ located on the side of the side of the film with respect to the end 31. At this time, the portion cut off by the perforations from a to b becomes the protrusion 2 of the dust bag 1, and the difference between the distance from the seal portion 5 to a and the distance from the seal portion 5 to b (hereinafter referred to as c Is the length of the protrusion 2. As described above, the length of the protrusion is preferably about 7 cm to 25 cm, and therefore c is also preferably within this range. The shape of the perforations 8 is not particularly limited as long as the above conditions are satisfied, and the shape similar to the protruding portion 2 of the dust bag 1 shown in FIG.

Further, when the continuous garbage bag 9 is cut off at the perforations 8, the tongue piece 6 is formed at the same time as the protruding portion 2, but the tongue piece 6 may be cut off by further providing perforations. However, in order to simplify the manufacturing process, the dust bag 1 may be used in a shape as shown in FIG. 3 without being separated. Usually, the trash bag 1 is carried with a knot formed by connecting the protrusions 2, but if the tongue piece 6 is left without being separated from the trash bag 1, the trash bag 1 will fall and the knot will be difficult to hold. In addition, the dust bag 1 can be carried by holding the tongue piece 6.

【Example】

 Next, an embodiment of the garbage bag 1 and the continuous garbage bag 9 of the present invention will be shown. First, a flattened tubular film 7 having a thickness of 0.04 mm and a folding diameter of 40 cm is obtained from a low-density polyethylene resin by inflation extrusion molding. A gusset portion 3 having a width of 5 cm is provided on both sides of the tubular film 7, and heat sealing is performed at intervals of 90 cm in the width direction of the tube to form the sealing portion 5. Next, two points a, a ′ located 0.5 cm away from the seal part 5 and 15 cm away from the seal part 5 and located 1.5 cm away from the gazette end 31. Insert perforations 8 into a substantially concave shape passing through b and b '. As a result, a continuous dust bag body 9 in which the dust bags 1 having the gusset portions 3 on both sides are continuous is obtained. Further, the continuous dust bag 9 is cut off at the perforations 8 to obtain the dust bag 1 of the present invention.

Since the garbage bag 1 thus obtained has the gusset portion 3, the lateral width of the garbage bag is narrow relative to the capacity, which is convenient for storage. In addition, the garbage bag had good stability after being filled with dirt, and it was difficult to fall. In addition, even if it fell, the opening did not leak because the opening was doubled. Further, the continuous garbage bag body 9 before the garbage bag 1 was separated was easy to store because the garbage bag 1 was connected. In particular, when the continuous dust bag 9 was rolled into a box and put in a box, the dust bag 1 was easily taken out and the appearance was good.

[0015]

【effect】

 The garbage bag 1 according to the present invention can be easily closed by tying the protrusion 2 provided in the opening 4 without using a closing tool such as a cord or a rubber band. Further, since there are four protrusions 2 and they can be tied in a taxi shape, they can be securely closed. Further, by providing the gusset portion 3 on the side surface, the width of the dust bag 1 can be narrowed.

[0016] Furthermore, the continuous garbage bag body 9 in which the tubular film is flatly folded and the seal portion 5 and the perforation 8 are provided is easy to store. A garbage bag 1 having a projecting portion 2 is obtained.
