Description

[Detailed Description of the Invention] <Field of Application> The present invention relates to a garbage bag that is provided with a glove portion that can be easily removed from the bag itself.

<Prior art> Garbage bags are usually made by continuously drawing molten thermoplastic resin, such as polyethylene, from a circular die, blowing air inside to increase its diameter, and folding it in half in the diametrical direction. Thereafter, this was cut to a predetermined length, and one of the opening sides, which was the cut side, was sealed. Therefore, its front shape is as shown in Figures 1 and 2, front 10a and back 10.
It is a rectangular bag with two sides b in contact. Incidentally, if I explain each part of the bag, the left side 14, the right side 1
5 corresponds to the diametrically folded side during manufacturing, the opening side 12 and the bottom side 13 are the cut sides during manufacturing, and the reference numeral 11 is a seal line applied to make the cut side the base side 13. . The size of the bag is usually about 75 cm (length) x 65 cm (width), and the thickness is about 15 to 60 μm in order to save on materials, making it extremely easy to tear.

In use, of course, garbage, fallen leaves, empty cans, etc. are picked up from the opening side 12 at random, and in most cases, once they are stored to half or slightly higher height, the remaining upper half is squeezed and tied to another string. It is closed by twisting it up and tying it in a ``hitoe knot,'' or by bringing both ears together and tying it in a ``top knot.''

In any case, it is rare to fill the opening 12 to its fullest extent, and when picking up trash, workers must prepare separate work gloves to avoid getting their hands dirty. I had to.

Another prior art is disclosed in Utility Model Application Publication No. 59-13453. In this prior art, the front and back sides of the bag body are kept overlapped near the opening side of the synthetic resin film bag 1, and the periphery is heat welded to the shape of a glove, so that a pair of glove parts are made with their fingertips facing each other. The glove portion is made removable by means of perforations or the like.

In such prior art, the glove part is formed by heat welding, and the proximal end of the glove part into which the hand is inserted is also heat welded, so that it is necessary to open the proximal end when in use. There is, and it is time-consuming.
In order to prevent this heat welding of the proximal end of the glove part, it is possible to apply a non-welding ink in advance to prevent heat welding, but it is clear that this will reduce productivity. .

Moreover, in this prior art, although it is possible to use the bag as a handbag by passing the hand through the hole formed after removing the glove part, it is difficult to close the upper opening after storing garbage as a garbage bag. As mentioned above, it may be difficult to tie, or it may be necessary to separately prepare a string or the like for tying.

Problems to be Solved by the Invention The object of the present invention is to provide an improved glove-removable garbage bag in which the opening side of the garbage bag can be easily closed and a disposable glove portion can be obtained.

Means for Solving the Problems The present invention is a rectangular thermoplastic synthetic resin bag 10 with two overlapping front and back sides 10a and 10b. 1
4, 15, and the base 13 where the front and back sides are connected,
The front and back sides of the bag 10 have separate opening sides 12, and the front and back sides 10a, 10b of this bag 10 have:
A pair of glove parts 20 having the opening side 12 as a base end and finger ends extending toward the bottom side 13 are connected to left and right sides 15,
The glove parts 20 are formed with a first interval m from each other and a second interval l between the glove parts 20, so that l≒2 m, and the peripheral edge of the glove part 20 is formed with a seal line 21 on the front side.
The two back sides are heat welded, and a tear line 16 is formed on the outer periphery of the seal line 21 of the glove part 20 at a distance from the seal line 21.・It is formed by a perforation for cutting that penetrates the two sides of the back, and after the glove part 20 is separated from the bag 10 at the cutting line 16, a width equivalent to twice the first distance m is formed through the gap. ear portions 14a, 15a having the second
Central pieces A and A having a width corresponding to the distance l are left facing the opening side 12, and at least two of these ears and the central piece can be tied together to close the top of the bag 10. This is a glove-removable garbage bag that is characterized by:

Embodiment For this reason, in the present invention, from the opening side 12 of a conventional rectangular thermoplastic resin bag whose front and back surfaces are in contact, as shown in FIGS.
Two glove-shaped seal lines 2 with the side facing the bottom side 13
1 and 21 are formed at an interval l, and perforation lines 16 and 16 are formed along the outer edges of the seal lines 21 and 21, respectively.

Here, pointing the finger ends 22 toward the base 13 does not mean that all the finger ends should be pointed toward the base 13, but it must be strictly in the sense that in addition to the middle finger, the remaining four fingers should also be directed toward the base 13 as much as possible. do not.

Such glove-shaped sealing lines 21, 21 are formed by heat sealing, ie thermal welding.

Cutting lines 16, 16 are made along the sealing lines 21, 21 at intervals on the outer periphery of the glove-shaped sealing lines 21, 21. glove part 20,2
It has the role of causing 0 to leave,
This is a perforation for cutting that passes through both the front and back sides.

The two glove-shaped shapes should originally be symmetrical on the left and right, but since they will be used as disposable glove parts 20, 20 by cutting them out as described below, they will not necessarily have the shape of the left and right hands. , it is not necessary to faithfully compare the shape of each of the five fingers. The degree of deformation, the width of the interval l, the interval m between the glove part and the left 14th and right 15th sides
Since the description is redundant, I will discuss it in the next section on effects.

<Function> When using this garbage bag, the user should cut the glove part 20,
20 and remove it from the main body.

When the two glove parts 20, 20 are removed in this manner, the left and right ear parts 14a, which have a width equivalent to twice the first interval m, are attached to the main body of the bag 10 through the gap caused by the removal of the glove parts. 15a and a pair of center pieces A, A having a width equivalent to the second interval l form the opening side 12.
and left behind. Further, inter-finger tongue portions 18a and 19a are left in the vicinity of the glove portion 20 from which the finger portions are removed.

The ears and center piece thus left can be used as a tie to close the opening after containing the debris, as can be seen in FIG.
Therefore, the shape of the glove part, the interval l between the gloves, the interval m between the glove and the left 14th and right 15th sides, etc. are set on the premise that it will serve as the remaining binding string, and may be modified.

If I had to give numerical values as a concrete example of l or m, it would be about l = 50 mm' m = 30 mm, and therefore l≒2 m.

The user uses the glove parts 20, 20 as gloves to collect and store trash without getting his hands dirty, and after that, ties the front and back center pieces A, A, or ties the left and right ear parts 14A. , 15A, the opening can be closed without using any special material.

In addition, if necessary, the adjacent inter-finger tongue piece portion 18
a, 18b, 19a, and 19b are tied together to prevent dirt from leaking between these interdigital tongues.

<Effects> Since the present invention is configured as described above, the user is not required to separately prepare gloves for collecting trash or materials for open binding. This glove can be easily removed from the garbage bag and can be used as is without any modification required. The top of the garbage bag can be easily closed to prevent the garbage contained therein from spilling out.

Furthermore, since the garbage bag itself is simply a conventional bag with a glove-shaped seal and a cutting line for easy removal, the increase in manufacturing costs and labor is avoided. It's almost not enough to say.
