Description

  The present invention relates to a plastic outer bag that can easily open a takeout opening and can take out one by one easily even when a plastic bag such as a garbage bag is accommodated.

2. Description of the Related Art Conventionally, a plurality of plastic bags used for garbage bags and the like are sold in a plastic outer bag.
The plastic outer bag is provided with a perforation so as to overlap the same part of both the front and back sides in a substantially semicircular shape toward the inside starting from the bottom of the outer bag, or either the front or back of the outer bag Perforations are provided in a substantially circular shape on the surface.
In order to take out the plastic bag, the film is first cut out from the perforation to form a takeout port, and then the plastic bag is pinched from the takeout port with a finger and pulled out.
To form the outlet, the film near the perforation of the outer bag is pulled to cut the perforation, but if the outer bag and the plastic bag overlap, only the outer bag near the perforation is pulled. It was difficult to pull the plastic bag stored at the same time. Also, if there is no space between the outer bag and the plastic bag assembly, it is difficult to separate the plastic bag into a single bag even if it is attempted to take out only one plastic bag. I had to take out the plastic bag. The plastic bag will be pulled out while maintaining a substantially conical shape with the pinched part as the top, but if multiple sheets are pulled together, the film mass pulled out will be larger than the size of the opening, There was a problem that the exterior bag was broken from the take-out port, and the body as an exterior bag was not formed until the stored plastic bag was used up.

Therefore, in order to easily take out the plastic bags one by one, the plastic bags are partially rolled up while being overlapped with each other, or the plastic bags are folded in two and the adjacent ones are pointed opposite each other. There has been proposed a method of storing the paper in a rectangular parallelepiped paper case (Patent Document 1). However, if a paper case is used, it can be easily taken out one by one, and although it can be printed beautifully, the paper case is much more expensive than the plastic bag that is stored, and it can be crushed during transportation and storage. There is also. Therefore, although there is a problem that it is difficult to take out, cheap plastic outer packaging bags are still frequently used.
Japanese Utility Model Sho 60-163275

  An object of the present invention is to provide a plastic outer bag in which a take-out port for taking out a plastic bag is easily formed, and the plastic bags can be easily taken out one by one.

As a result of intensive studies, the present inventors have found that the above problems can be solved by providing an oblique guide wire with a seal near the take-out port of the plastic outer bag, and have reached the present invention. That is, according to the present invention,
(1) A perforation 3 is provided at the center of the bottom so that the base 6 is a starting point and an ending point, and overlaps the same place on both the front and back sides toward the inside.
Provided is a plastic packaging outer bag 1 for bag storage, characterized in that two seal lines 4 are provided obliquely in a direction away from the base 6 from the vicinity of the base toward the side 7.
(2) The plastic outer bag 1 for storing a bag according to (1), wherein the perforation 3 provided in the center of the bottom is provided so as to draw a substantially semicircular shape,
(3) A plastic bag storing exterior bag 1 according to (1) or (2), wherein a predetermined number of plastic bags 2 are stored.

  The plastic outer bag 1 of the present invention can easily form the takeout port of the plastic bag 2, the plastic bags 2 can be taken out one by one reliably, and the plastic outer bag 1 is not torn from the takeout port.

The present invention will be described below.
For the plastic outer bag of the present invention, a soft thermoplastic resin that can be heat-sealed, such as low-density polyethylene, high-density polyethylene, linear low-density polyethylene, and polypropylene, is used. These soft thermoplastic resins may be used singly or in combination, and may be a single layer or a multilayer.
As a method for forming these soft thermoplastic resins into a film, a known method such as an inflation method or a casting method may be used.

  As a method of processing the soft thermoplastic resin film obtained by the above method into a bag shape, the tube-like film obtained by the inflation method may be cut to a suitable length and the openings at both ends may be sealed. Alternatively, one rectangular film may be folded in half to seal three sides other than the mountain fold, or two rectangular films may be stacked to seal four sides.

  In addition, the surface of the plastic outer bag 1 may be printed as necessary, such as the standard of the plastic bag 2 accommodated and the number of containers.

Hereinafter, the present invention will be specifically described with reference to the drawings.
FIG. 1 is a schematic front view showing an example of a plastic outer bag 1 for bag storage according to the present invention.

  The plastic outer bag 1 is formed by heat sealing the upper and lower ends of a tubular plastic film cut to a predetermined length.

In FIG. 1, the perforation 3 is formed so that the bottom 6 of the plastic outer bag 1 starts and ends and overlaps with the same place on both the front and back surfaces toward the inside of the plastic outer bag 1 and draws a substantially semicircular shape. Is provided.
The size of the portion where the perforation 3 is provided is not particularly limited as long as the plastic bag 2 can be taken out one by one. The shape may be a triangle or a quadrangle as well as a substantially semicircular shape, but is preferably a substantially semicircular shape that does not have a corner portion that tends to be the starting point of film breakage of the plastic outer bag 1.

In FIG. 1, two seal lines 4 are provided symmetrically diagonally in a direction away from the base 6 starting from the middle portion of the bottom seal 5 of the plastic outer bag 1 and starting from both sides 7. .
Although the two seal lines 4 are in contact with each other at the intermediate portion of the bottom seal 5, the start points of the two seal lines 4 do not have to coincide with each other, and the start points do not have to be in contact with the bottom seal 5. Moreover, the end point does not necessarily need to intersect the side 7, and the seal line 4 may be provided so as to be close to the side 7.

FIG. 2 is a schematic front view showing another example of the plastic outer bag 1 for bag storage according to the present invention.
In FIG. 2, heat sealing is applied to both cut portions of the tubular plastic film cut to a predetermined length as in FIG. 1, but one side that is not heat sealed is defined as the base 6. . In FIG. 2, two diagonally in the direction away from the base 6 starting from the vicinity of the center of the bottom, that is, the vicinity of the perforation 3 provided so as to draw a substantially semicircular shape, and starting from the vicinity of the side 7 on the adjacent side. The seal line 4 is provided symmetrically. The starting point of the seal does not need to be in contact with the base 6, but is preferably as close to the base 6 as possible.

  The slanted seal line 4 on the bottom of the exterior bag prevents the movement of the assembly of the stored plastic bag 2, and the portion provided with the perforation 3 overlaps the assembly of the stored plastic bag 2. An incompatible space is created. Therefore, only the plastic outer bag 1 in the portion where the perforation 3 is provided can be picked with a finger, and the perforation 3 portion can be cut to easily form a take-out port. At the same time, when the plastic bag 2 is taken out, the plastic bag 2 can be separated one by one in the space between the outer bag and the assembly of the plastic bags 2, so that only one plastic bag 2 can be taken out without fail. Is possible.

  Further, since the seal line 4 serves as a guide and the plastic bag 2 moves along the seal line 4, the assembly of the plastic bag 2 is hindered from moving in the direction in which the plastic bag 2 is taken out by the seal line 4. The plastic bag 2 is reliably separated into only one sheet. Therefore, film tearing from the outlet of the plastic outer bag 1 is less likely to occur.

The distance d from the end on the side 7 side of the seal line 4 to the base 6 is preferably 10 to 50 mm.
If the distance d is smaller than 10 mm, a sufficient space cannot be obtained between the assembly of the plastic outer bag 1 and the plastic bag 2, and the portion provided with the perforation 3 and the assembly of the plastic bag 2 overlap each other. It becomes difficult to cut the eyes 3, and it becomes difficult to separate the plastic bag 2 into one sheet, which is not preferable.
On the other hand, if the distance d is larger than 50 mm, the plastic outer bag 1 is more than necessary than the assembly of the plastic bags 2 although there is an effect of preventing the separation of the plastic bag 2 and the tearing of the film from the vicinity of the outlet of the outer bag. It becomes large and is not preferable.

  The seal line 4 may be dotted or wavy as long as it has a linear appearance as a whole. The seal line 4 may be a curved line as long as the effect of the present invention is not hindered.

The plastic outer bag 1 of the present invention stores a predetermined number of plastic bags 2.
As a method for storing the plastic bag 2, it is not necessary to use any special method in the same manner as the plastic bag currently on the market. For small plastic bags 2, a predetermined number of sheets may be stacked and stored in a plastic outer bag 1, and for large plastic two bags, a predetermined number of sheets may be stacked and then folded in half. What is necessary is just to accommodate so that the base 6 of the plastic exterior bag 1 may adjoin in parallel. Also, in a larger plastic bag 2 like a garbage bag, it is folded to a predetermined width, then a predetermined number of sheets are stacked, folded again in half so as to maintain the predetermined width, and the folded mountain fold line is a plastic outer bag. What is necessary is just to accommodate so that it may adjoin to the base 6 of 1 in parallel.

  The plastic outer bag 1 containing the plastic bag 2 has a perforation 3 provided in a substantially semicircular shape at the center of the bottom that serves as an outlet for the plastic bag 2, and is inclined from the vicinity of the center of the base 6 toward the side 7. By providing two seal wires 4 on the plastic bag 2, a plastic bag 2 can be easily taken out without damaging the plastic bag 2, and the plastic bag 2 can be easily taken out without damaging the plastic bag 2. The bag 1 can be provided.

It is the schematic of the front which shows an example of the plastic exterior bag 1 for bag storage of this invention. It is the schematic of the front which shows another example of the plastic exterior bag 1 for bag storage of this invention.
