Description

  The present invention has a continuous belt-like bag body in which a large number of bag bodies are continuously connected in series, such as a garbage bag or a shopping bag (a plastic bag), and the continuous roll bag obtained by winding the continuous belt-like bag body into a roll. In particular, the present invention relates to a simple packaging technique for the roll-shaped continuous bag body.

  Since the roll-shaped continuous bag body is a roll-shaped continuous bag body made of a series of a large number of bag bodies, the terminal portion of the belt-shaped continuous bag body is conventionally attached with an adhesive label. A device that is fastened to a main body roll portion is known (see Patent Document 1).

  In the above-mentioned conventional technology, since it can be packed into a packaging state without using packaging materials compared to the conventional one in which a roll-shaped continuous bag body is packaged with a dedicated packaging bag, resource saving and cost reduction, There is an advantage of reducing garbage.

However, when the terminal portion is fastened to the main body roll portion with the adhesive label as described above, the adhesive label needs to be directly attached to the belt-like continuous bag body.
Therefore, when the adhesive label is peeled off with use, there is a problem that the belt-like continuous bag body is torn or soiled due to the adhesive force.
In addition, since the adhesive label is only applied from above so as to straddle the terminal part and the main body roll part, there is a problem that the fastening of the terminal part is likely to be unstable and the winding state of the belt-like continuous bag body is likely to be disturbed. It was.
In addition, since the adhesive label uses synthetic adhesive paste, there is a problem that extra carbon dioxide is generated during incineration, and the amount of processing increases by the amount of the synthetic adhesive paste, which places a burden on the environment. Moreover, since the adhesive label uses adhesive paste, there is also a problem that it is difficult to recycle.

Therefore, conventionally, as shown in FIGS. 10 and 2, a simple packaging technique is known in which the terminal portion 1 a of the belt-like continuous bag body 1 is wound around the main body roll portion 1 b via the wrapping paper piece 2.
In this case, the wrapping paper piece 2 is simply a paper piece formed in a rectangular shape, and a sandwiching part 2a (shown by parallel diagonal lines in the figure) sandwiched between the terminal part 1a and the main body roll part 1b, A winding portion 2b extending from the sandwiching portion 2a and wound around the main body roll portion 1b at least once, and by adhering 2c the winding end portion of the winding portion 2b to the outer surface of the winding portion 2b, It is formed so that the terminal portion 1a of the belt-like continuous bag body 1 is wound around the main body roll portion 1b through the wrapping paper piece 2.

When such a wrapping paper piece is used, the winding end portion of the winding portion is bonded to the outer surface of the winding portion, so that it is not directly bonded to the belt-like continuous bag body.
Therefore, when the adhesive is peeled off, the belt-like continuous bag body is not torn or soiled by the adhesive force.

  In addition, the sandwiching part is sandwiched between the terminal part and the main body roll part, and then the winding part is wound around the main body roll part. The body does not slip or fall off, the winding with the wrapping paper pieces is stable, and the winding state of the belt-like continuous bag body is less likely to be disturbed.

However, such a wrapping paper piece is discarded as garbage, and it is preferable to reduce the area as much as possible from the viewpoint of reducing the amount of garbage.
At this time, it is necessary not to impair the winding function of the wrapping paper piece.
JP 2001-2082 A

  The present invention uses a simple packaging technique using a wrapping paper piece, reduces the area of the wrapping paper piece without impairing the winding prevention function of the wrapping paper piece, and can reduce the amount of dust. The problem is to provide a continuous bag.

In order to solve the above problems, the roll-shaped continuous bag of the present invention (Claim 1)
A continuous belt-like continuous bag body is formed by connecting a large number of bag bodies by a broken broken line, and this continuous belt-like bag is rolled up into a roll shape,
The terminal part of the belt-like continuous bag body is fastened to the main body roll part via a wrapping paper piece,
The wrapping paper piece includes a sandwiching part that is sandwiched between the terminal part and the main body roll part, and a winding part that extends from the sandwiching part and is wound around the main body roll part by at least one turn,
By adhering the winding end of the winding part to the outer surface of the winding part, the terminal part of the belt-like continuous bag body is formed so as to be wound around the main body roll part via the wrapping paper piece,
A cutting part for reducing the area of the sandwiching part is formed in the sandwiching part of the wrapping paper piece.

  In the roll-shaped continuous bag body according to claim 1, there is an aspect (invention 2) in which the cut portion is formed by notching a wrapping paper piece in the sandwiching portion.

  In the roll-shaped continuous bag body according to claim 1 or 2, there is an aspect (invention 3) in which the cut portion is formed by making a hole in the wrapping paper piece in the sandwiching portion.

  FIG. 1 is a perspective view of a rolled continuous bag according to an embodiment of the present invention in a state in which a terminal portion is unfolded, and FIG. 2 is an explanatory side view of a state in which the rolled continuous bag is wound with a wrapping paper piece. It is.

In FIG. 1, reference numeral 1 denotes a continuous belt-like bag body, in which a large number of bag bodies 10 are connected in series by a cut broken line 11 and are continuous in a belt shape, and the cut broken line 11 extends across the entire width of a cylindrical plastic film. Are formed at regular intervals, and a bag bottom welded portion 12 is formed in the vicinity of the cut broken line 11.
And the roll-shaped continuous bag body A is formed by winding up this strip | belt-shaped continuous bag body 1 in roll shape, In this embodiment, it winds up so that the opening side of the bag body 10 may become a winding end. Yes.
In addition, in order to make the roll-shaped continuous bag body A compact, both side portions of the belt-shaped continuous bag body 1 are folded inward and wound up in a roll shape.

  And in this roll-shaped continuous bag body A, the terminal part 1a of the strip | belt-shaped continuous bag body 1 is wound around the main body roll part 1b via the wrapping paper piece 2. FIG.

The wrapping paper piece 2 includes a clamping part 2a (indicated by parallel oblique lines in the figure) sandwiched between the terminal part 1a and the main body roll part 1b, and extends from the clamping part 2a to the main body roll part 1b at least once. The winding part 2b wound above is provided.
And the end part 1a of the strip | belt-shaped continuous bag body 1 is wound around the main body roll part via the said wrapping paper piece 2 by making the winding end part of the said winding part 2b adhere 2c to the outer surface of the winding part 2b. It has become.

Thus, since the winding end portion of the winding portion 2b is adhered to the outer surface of the winding portion 2b, it is not directly adhered to the belt-like continuous bag body 1. Therefore, when the adhesion is peeled off, The belt-like continuous bag 1 is not torn or soiled by the adhesive force.
Moreover, since the winding part 2b is wound around the main body roll part 1b after the sandwiching part 2a is sandwiched between the terminal part 1a and the main body roll part 1b, the displacement movement of the wrapping paper piece 2 can be suppressed. The belt-like continuous bag body 1 is not displaced from the slip-in paper piece 2 or dropped off, and the winding stop by the curly paper piece 2 can be stabilized.

  The basic shape of the wrapping paper piece 2 is a rectangular shape as shown in the conventional example of FIG. 10, and has a width narrower than the width of the belt-like continuous bag 1 and a constant width from the sandwiching portion 2a to the winding portion 2b. The length of the sandwiching part 2a is formed to be long enough to be sandwiched between the terminal part 1a and the main body roll part 1b, and the length of the winding part 2b is longer than the circumference of the main body roll part 1b. Is formed.

The wrapping paper piece 2 is formed with a cutting portion 20 (indicated by phantom lines in the figure) for reducing the area of the holding portion 2a in the holding portion 2a.
In this case, as shown in FIGS. 1, 3, 4, and 5, the cut portion 20 can be formed by cutting out the wrapping paper piece 2, and the cut portion 20 can be wound as shown in FIGS. 7 and 8. It can be formed by making a hole in the slip-in paper piece 2 or can be formed by combining both a notch and a hole as shown in FIG.

The cutting part 20 of FIG. 1 is formed by notching the leading edge of the wrapping paper piece 2 in a mountain shape in the clamping part 2a.
The excision part 20 in FIG. 3 is formed by obliquely notching the leading edge of the wrapping paper piece 2 in the clamping part 2a.
The cutting part 20 of FIG. 4 is formed by notching both side edges of the wrapping paper piece 2 with a certain width in the clamping part 2a.
The cutting part 20 of FIG. 5 is formed by notching the central part of the wrapping paper piece 2 with a certain width in the clamping part 2a.
In addition, as shown in FIG. 6, the center part of one strip-shaped raw material paper piece 29 is cut | disconnected along the crank-shaped cutting line 29a, and the winding paper piece 2 shown in FIG. 4 and FIG. 5 show. Two wrapping paper pieces 2 can be manufactured at the same time, and the production efficiency and the yield of the strip-shaped raw paper pieces 29 can be improved.
The excision part 20 of FIG. 7 is formed by making a large number of small holes in the wrapping paper piece 2 in the clamping part 2a.
The cut part 20 of FIG. 8 is formed by making a long hole in the wrapping paper piece 2 in the clamping part 2a.
9 is a combination of FIG. 3 and FIG. 7, and is formed by cutting the leading edge of the wrapping paper piece 2 diagonally in the clamping part 2 a and making a number of small holes. .
The shape of the hole may be round, oval, square or the like.

  Thus, since the cutting part 20 was formed in the clamping part 2a of the wrapping paper piece 2, the area of the wrapping paper piece 2 can be reduced, and when the wrapping paper piece 2 after use is discarded as garbage, We can plan garbage weight loss. Needless to say, the used wrapping paper piece 2 can be used as a recycled paper raw material and processed to produce recycled paper.

  In addition, since the sandwiching portion 2a is sandwiched between the terminal portion 1a and the main body roll portion 1b, it is difficult for external force to be applied to the sandwiching portion 2a, and the strength of the sandwiching portion 2a associated with the formation of the cut portion 20 is reduced. Even if it falls, the effect | action of this clamping part 2a is not spoiled, By this, the winding stop by the wrapping paper piece 2 can be stabilized.

As mentioned above, although the Example of this invention was described with drawing, a specific structure is not restricted to this.
