Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage collection bag, and more particularly to a garbage collection bag that can easily close a storage port even when a full garbage is stored in the bag.

[0002]

2. Description of the Related Art Generally, when a storage port of a garbage collection bag storing garbage is closed, two opposite sides of a peripheral portion of the storage port are closed.
After pulling the place and making the periphery of these two places a string,
A method is used to combine them.

[0003] However, in such a method, when a large amount of dust is stored in the dust collection bag such that the upper surface of the dust reaches the vicinity of the periphery of the storage opening, the periphery is tied to the periphery at the two locations. There is no room for a knot for matching.

[0004] Therefore, the capacity of the garbage to be stored must be reduced in advance, and the internal volume of the garbage collection bag cannot be maximized.

Therefore, conventionally, when an amount of dust close to the maximum internal volume of the dust collection bag is to be stored and closed, an adhesive tape is applied to the periphery of the storage opening, and the bag is closed and closed. Has been taken.

In addition, without reducing the amount of garbage,
As a thing that can be closed easily, the peripheral part of the storage opening is bent several centimeters over the entire circumference, the tip of this bent part is adhered to the main body to create a cylindrical space,
There has also been proposed a configuration in which a string or the like different from the bag body is passed through the space, and a garbage collection bag that can pull the string and close it like a drawstring.

[0007]

However, in the above-mentioned method of sealing with an adhesive tape, when closing,
You must always have the adhesive tape within easy reach or carry it with you. Therefore, it is troublesome and the work efficiency is poor.

[0008] Further, in the above-mentioned garbage collection bag which can be closed in the form of a drawstring, the production cost is high.
This is a major problem for mass-produced garbage collection bags.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a garbage collection bag that can easily close the storage opening even when storing an amount of garbage close to the maximum internal volume of the bag and that does not require any production cost. is there.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the overall configuration of an embodiment of the present invention. The garbage collection bag is constituted by a polymer resin sheet using polyethylene (hereinafter, referred to as a “sheet”).

First, the bag body 1 is made by cutting a long tubular body (not shown) formed from the above-mentioned sheet into a predetermined length. One end of the tubular sheet is closed by heat fusion or the like to become the bottom 2 of the bag body 1, and the other end of the tubular sheet opposite to this becomes an openable storage port 3.

FIG. 1 shows a garbage collection bag before use. The bag body 1 has creases on both sides of the sheet.
It is folded flat like a double sheet.

The above is the same as the configuration of the conventional garbage collection bag, but the garbage collection bag of this embodiment further has the following configuration.

A break line 5 is formed near the peripheral edge 4 of the storage opening 3 in parallel with the peripheral edge 4, but this break line 5 is not provided at both ends of the bag, and is an interrupted portion 5a, 5b. . A dividing line 6 reaching the peripheral edge 4 is formed substantially at the center of the breaking line 5.

The breaking line 5 is formed by making an intermittent cut such as a perforation in the sheet, and the outside portion 7 is held by a person by simply grasping the outer portion 7 of the breaking line 5 and pulling it lightly. This is for enabling the bag to be separated from the bag body 1. Further, the dividing line 6 is also provided with an intermittent cut like the breaking line 5. However, this dividing line 6
May be a continuous cut. In this intermittent cutting, the length of the cutting and the pitch of the cutting are set according to the material to be used and the like, and are not particularly limited.

The breaking line 5 and the dividing line 6 also penetrate the double back sheet of the bag body 1, and the outer portion 7 can be separated as a double sheet. it can.

FIG. 2 is a view showing a state in which the outer portion 7 is cut off to form string portions 7a and 7b. Break line 5 above
When the dividing line 6 is cut and the outer portion 7 is separated from the bag body 1, a string portion 7a connected to the bag body 1 at the interrupted portion 5a and a string portion 7b connected at the interrupted portion 5b are formed.

The string portions 7a and 7b are composed of two sheets, a back side and a front side. Therefore, after separation, the sheet is divided into two sheets from the leading end, which makes it difficult to handle. Therefore, as shown in FIG.
Are knotted at these tip portions by using a knot 7c such as a corner knot.

The bag body 1 is provided with a plurality of insertion portions 8 at equal intervals below the breaking line 5 and along the peripheral edge 4 of the accommodation opening 3.
Is provided. These insertion portions 8 are cut holes penetrating the double sheet.

In using the garbage collection bag having the above structure, first, the user separates the outer portion 7 by hand to form string-like portions 7a and 7b, and then opens the double sheet to remove the trash from the storage port 3. Then, two sheets of the peripheral edge 4 are bound. Then, as shown in FIG. 3, from each end of the accommodation port 3 toward the center, each of the cord-like portions 7a and 7b is
The heavy sheet is sewn alternately from the front and back sides. Furthermore, each string-like portion 7 protruding from two insertion portions 8 at substantially the center is provided.
When a and 7b are pulled in the directions of the arrows shown in FIG. 3, respectively, as shown in FIG. 4, the accommodation opening 3 is narrowed down into a drawstring.
After that, the remaining cord portions 7a and 7b can be tied together, and the storage port 3 of the garbage collection bag can be closed.

As a method for inserting the string-like portions 7a and 7b, a method for spirally passing the strings 7a and 7b may be used as shown in FIG. According to this method, the degree of sealing of the garbage collection bag is higher than that of the above method shown in FIG.

The insertion portion 8 provided in the garbage collection bag of this embodiment is formed by cutting a double sheet, and the insertion portion 8 may have a slit shape, a round hole shape, or a cut shape. It may be in the shape of a long hole, and is not particularly limited as long as it is a shape through which the string portions 7a and 7b can be inserted.

The number and the interval of the insertion portions 8 may be reduced and the interval may be increased if importance is placed on the simplicity of the operation, and the number may be increased and the interval may be decreased if importance is placed on the tightness of the bag. Good. As described above, the shape, the number, and the interval of the insertion portions 8 may be determined by the balance of the type of dust, the strength of the sheet material, and the like, and are not particularly limited. Further, although the string portions 7a and 7b are connected to the bag main body 1 at the interrupted portions, it is possible to eliminate the interrupted portions and completely separate the string portions from the main body.

FIGS. 6 and 7 show a second embodiment of the present invention. FIG. 6 shows the entire configuration of the garbage collection bag before use. FIG. 7 shows the operation sequence from the formation of the string-shaped portion 7d to the closing of the storage port 3.

As shown in FIG.
An interruption portion 5c is provided at one location on the left end side of the bag body 1. Thus, when the outer part 7 is separated,
As shown in (a), a single cord-like portion 7d connected to the bag body 1 at the interrupted portion 5c is formed. Further, in the present embodiment, since the folded portion on the side surface of the seat is the tip portion of the string-shaped portion 7d, it is not necessary to form the knot 7c shown in FIG. 2 at the time of use. Other details of the configuration are the same as in the first embodiment.

In the order of operation, the outer portion 7 is cut off to form a string-like portion 7d as shown in (a), and after the dust is stored, the string-like portion 7d is inserted into the insertion portion 8 as shown in (b). Then, as shown in (c), the storage opening 3 is closed in a drawstring shape.

FIGS. 8 and 9 show a third embodiment of the present invention. FIG. 8 shows the entire configuration of the garbage collection bag before use. FIG. 7 shows a sequence of operations from the formation of the cord portions 7e and 7f to the closing of the storage port 3.

As shown in FIG. 8, the present embodiment has a
Are provided with two interrupted portions (an interrupted portion 5d of the top sheet and an interrupted portion of the back sheet not shown). Therefore, two outer portions 7 are formed on the peripheral edge 4. When the outer portions 7 are cut off, two string portions 7 e and 7 f connected to the bag body 1 are formed as shown in FIG. Further, as in the second embodiment, the folded portion on the side surface of the seat is the leading end of the string-shaped portions 7e and 7f, so that the knot 7c does not need to be formed at the time of use. Other details of the configuration are the same as in the first embodiment.

Next, the operation will be described in the order of operation. As shown in FIG.
After the garbage is stored, the string-like portions 7e and 7f are respectively passed through the insertion portions 8 as shown in (b), the storage opening 3 is sewn, and as shown in (c), the storage opening 3 is formed into a drawstring. Close to.

In each of the above-mentioned embodiments, the working order in use is such that the outer portions 7 are cut off and the string-shaped portions 7 are separated.
The working order is not limited to storing the dust after the steps a, 7b, 7d, 7e, and 7f are performed. 7 and cut off each of the string portions 7a, 7b, 7
They may be used in the order of d, 7e, 7f. In particular, in the second and third embodiments, the string-like portions 7d, 7e, and 7f are configured so as not to be separated from the tip portion, and it is not necessary to form a knot 7c such as a corner knot. Absent.

With the above arrangement, each of the above embodiments can close the accommodation opening 3 in a drawstring shape. Compared with a conventional garbage collection bag that closes two places on the peripheral edge 4 of the storage opening 3, it is possible to store a large amount of garbage, that is, a garbage close to the original maximum internal volume of the bag body 1. Even if such a large amount of garbage is stored, the storage port 3 can be closed securely and easily.

Further, in the first and third embodiments, the two cord-like portions 7a, 7b, 7e, 7f are pulled and closed like a drawstring. For this reason, the storage port can be closed evenly and more evenly than in the case of the second embodiment.

Next, the process of forming the garbage collection bag will be outlined. Generally, a garbage collection bag is formed by cutting a sheet having a long cylindrical body into a predetermined length. First, this cylindrical sheet is sent to the production line as a double sheet with both sides folded and flat.

Here, the molding machine cuts the sheet in the horizontal direction at regular intervals, and at the same time, the line along the cutting line is fused (heat-sealed) by heat or the like. In this one molding process,
The open accommodation opening 3 and the bottom 2 closed by fusing the double sheet can be formed at the same time.

On the other hand, the garbage collection bag of the present embodiment has a break line 5, a division line 6, and an insertion portion 8 formed near the peripheral edge 4 of the storage port 3 during the molding. That is, a saw-like punch corresponding to the breaking line 5 and a cutter having blades provided at regular intervals corresponding to the cuts of the insertion portion 8 are prepared, and these punches and cutters are attached to both ends of the bag body. Simultaneously with the cutting, the sheet is lowered to a predetermined position near the peripheral edge 4 and formed by penetrating both sheets on the front side and the back side.

That is, in the garbage collection bag of the present invention, a punch or a cutter for forming the above-mentioned breaking line or dividing line is provided in a conventional garbage collection bag molding apparatus, and a drive system provided in the apparatus is used as it is. Production is possible.

As another forming method, the punch and the cutter may be a roll cutter or the like provided with a blade or the like on the circumference of a rotating disk, and the roll cutter or the like may be rolled on a sheet. The breaking line 5 and the insertion portion 8 may be formed.

The breaking line 5, the dividing line 6, and the insertion portion 8 in the present embodiment have a structure in which the sheet is simply cut. Therefore, since no scrap is generated from the sheet in the above-described forming step, the processing of the scrap is unnecessary.

As described above, the garbage collection bag of the present invention is suitable for mass production because of its simple configuration and simple molding, and has a small burden in terms of cost. This is particularly useful in a garbage collection bag in which an increase in mass production cost is a fatal problem.

[0043]

According to the garbage collection bag of the present invention, a break line is formed along the periphery of the storage opening, and the outer portion of the break line can be cut off as a string portion. The configuration having a plurality of insertion portions for passing the dust allows the storage port to be reliably closed even if the amount of dust near the maximum internal volume of the dust collection bag is stored. Further, there is no need to prepare a separate string or adhesive tape, and the operation is simplified. Further, since the above configuration is suitable for mass production, an increase in production cost can be suppressed.

Further, one or two or more interrupted portions are provided on the breaking line, and when the outer portion is cut off to form a string-shaped portion, the string-shaped portion is connected to the bag body at the interrupted portion. Thereby, the accommodation opening can be simply closed simply by pulling one end of each cord-shaped portion through the insertion portion.

Further, if the string-like portion has a dividing line and is divided into a plurality of cord-like portions by the dividing line, the string-like portion after insertion can be easily connected and handled. In addition, the entirety of the storage port can be closed with good balance.
