DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag for packaging roll paper (mainly for toilets).

[0002]

2. Description of the Related Art Conventionally, roll paper wrapping bags are generally formed by wrapping roll paper in, for example, four or six one-tiered sheets and stacking them in two or three tiers. The packaging bag used for this packaging is, for example,
As shown in FIG. 10, a bag main body 4 is formed below the seal portion 2 where the tubular film is welded flat, as a boundary.
It has a structure in which a grip portion 3 is formed on the upper side. In this case, the bag body 4 accommodates the roll paper R in a stacked state. In order to form an outlet for the roll paper R, conventionally, a cut-out dashed line is formed on the upper portion of the bag body 4. 8 is formed in a curved shape. Therefore, by opening the cut-out dashed line 8, it is possible to form a take-out opening in the upper portion of the bag body 4, and the roll paper R is taken out from this opening.

[0003]

However, in the conventional packaging bag, the take-out opening can be formed only within the range of the cut-off broken line 8, so that the opening range of the take-out opening is narrow, and in particular, the grip portion 3 has Since the gripping portion 3 remains as it is over the entire length of the bag, there is a problem that the opening of the take-out opening cannot be widened because the grip portion 3 is in the way. Conventionally, when the used packaging bag is used as a garbage bag after taking out all the roll paper R, the gripping portion 3 remains as it is over the entire length of the bag as described above. It is difficult to tear off part 3 by hand. As described above, since the upper end of the packaging bag is left closed by the gripping portion 3, it is inconvenient to use it as a garbage bag as it is. Therefore, in order to use the used packaging bag as a garbage bag, a time-consuming operation such as cutting off the grip portion 3 including the seal portion 2 with scissors and opening the upper portion of the bag body portion 4 is necessary. become.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. When an opening for taking out roll paper is opened, the opening can be cut open so that the opening range is widened. It is an object of the present invention to provide a roll paper packaging bag that can be easily used as a garbage bag when the used packaging bag is used as a garbage bag. I have.

[0005]

Means for Solving the Problems In order to solve the above problems, a packaging bag for roll paper of the present invention (claim 1) comprises:
A bag is bounded by the seal where the tubular film is welded flat.
A main body, and a gripper with a notch for finger hooking at the center
Is formed, and a reinforcing piece is provided on the grip portion.
First, the gripping portion is vertically cut from the upper edge of the gripping portion, and further a cut-out dashed line is formed extending beyond the sealing portion to the upper portion of the bag body portion , and the reinforcing piece is vertically extended from the upper edge to the lower edge.
The vertical broken line to be cut was formed .

In this case, the cut-out dashed line is formed by one line (claim 2). The cut-out dashed line is formed by one line from the upper edge of the grip portion to the middle of the grip portion, and branched from the tip to two lines. (Claim 3), an embodiment in which the cut-off dashed line is formed by one piece from the grip portion to beyond the seal portion, and is branched into two pieces from the tip (Claim 4). Further, there is a mode in which two cut-out broken lines are formed (claim 5). Further, in a case where the cut-out dashed line is branched into two at the grip portion and when two cut-out dashed lines are formed, a connection cut-out dashed line whose both ends are continuous with the two cut-out dashes is formed in the bag body ( There is claim 6).

In the roll paper packaging bag of the present invention, when the roll paper is taken out, a cut-out dashed line is cut open, whereby the gripping portion is cut longitudinally and a cut is made in the upper portion of the bag body continuously. It is formed.
In a packaging bag for roll paper, a reinforcing piece is provided to reinforce the gripping portion in order to support the weight of the roll paper with the gripping portion. Then, when the grip portion is to be longitudinally cut, it is necessary to vertically cut the reinforcing piece at the same time, but since a vertical broken line is also formed for this reinforcing piece, it is possible to vertically cut the reinforcing piece along the vertical broken line. it can. Therefore, it is possible to easily longitudinally cut the grip portion while reinforcing the grip portion with the reinforcing piece. Then, when the two gripped portions that have been cut vertically are opened to be pulled to both sides, the upper portion of the bag main body portion is opened left and right with this, and the opened portion can be used as an outlet for the roll paper. In this manner, the grip can be cut longitudinally, and the cut can be formed in the upper portion of the bag body continuously to the vertical cut, so that the upper surface of the packaging bag can be opened in a wide range. Therefore, the roll paper can be taken out smoothly.

In the case where the cut dashed line is branched into two in the middle of the grip portion or when the cut dashed line is formed in two lines, the seal remains in a bridge shape between the cut dashed lines. Since the bridge seal portion remains in a state in which the central portion of the opening is closed, it functions as a dust remover during storage until the roll paper is completely removed. When using the packaging bag as a garbage bag after use,
This bridge seal will be torn.

Further, when the cut-out dashed line is formed by one line or when the cut-out dashed line is branched into two in the bag main body, the bridge seal portion does not remain. You can widen the opening over it,
It can be used as a garbage bag as it is. In addition, in the case where the connection cut-out dashed line is formed, if the connection cut-out dashed line is cut in from the beginning, the bridge seal portion can be cut off, so that the opening can be widened widely and used as it is as a garbage bag. Conversely, the bridge seal portion may be left at first by leaving the connection cut-out dashed line without cutting, and after using the roll paper, the connection cut-out dashed line may be cut off to cut off the bridge seal portion.

Further, in the present invention, there is a mode (claim 7) in which the broken broken line of the grip portion and the broken vertical broken line of the reinforcing piece are shifted in position. When the position of the cut dashed line of the grip portion and the position of the vertical broken line of the reinforcing piece match, there is a risk of being cut off from the position of the cut dashed line and the vertical broken line due to the tensile load applied when carrying, but if the positions of both broken lines are shifted, it will be added when carrying. The tensile load can be dispersed and cutting can be prevented. Therefore, it is possible to easily longitudinally cut the grip portion while reinforcing the grip portion with the reinforcing piece.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a cutaway front view showing a packaging bag according to a first embodiment of the present invention, FIG. 2 is a perspective view showing a packaging bag in which roll paper is stored, and FIG. 3 is a packaging having a take-out opening opened. It is a perspective view showing a bag.

The packaging bag A is manufactured by using the tubular film 1, and gussets 10, 10 which are folded inward are formed at both ends of the tubular film 1.
A boundary seal portion 2 formed by flatly welding the cylindrical film 1 is formed in a portion near the upper end of the cylindrical film 1, and a grip portion 3 is formed on an upper side of the boundary seal portion 2, and a lower side is formed. A bag body 4 is formed at the bottom. The central portion of the grip 3 is reinforced by superimposing a reinforcing piece 3a. An upper edge seal portion 35 is formed along the upper edge 30 of the grip portion 3, and vertical seal portions 31, 31 are provided between the upper edge seal portion 35 and the boundary seal portion 2 on both side portions. In addition, vertical seal portions 32, 32 and a horizontal seal portion 33 are formed in a central portion, and cuts 34, 34 for finger hanging are formed. The lower end of the cylindrical film 1 is opened at first, and closed by a seal after the roll paper R is stored in the bag body 4.

The packaging bag A has an upper edge 3
A cut-off broken line 5 is formed which extends longitudinally from 0 to the gripping portion 3 and further extends beyond the boundary seal portion 2 to the upper portion forming the upper surface of the bag body portion 4. The cut-off dashed line 5 extends downward from the upper edge 30 of the grip portion 3 and is formed by a single dashed line portion 5a up to the middle of the grip portion 3 and branches from the point into two branched dashed line portions 5b, 5b. Each extension is formed so as to extend obliquely outward and then downward, and at the extended end thereof, there are formed notches 50 and 50 for stop holes for preventing tearing.

FIG. 4 is a perspective view showing an example of a method for manufacturing the packaging bag A. In this case, while the cylindrical film 1 is being unwound, cut-out broken lines 5 are formed on the cylindrical film 1 at regular intervals. Next, the band-shaped roll film 39 serving as the reinforcing piece 3a is extended to the sealing machine 6 so as to overlap the central portion of the cylindrical film 1, and the sealing machine 6 uses the sealing sections 2, 3
5, 31, 32, and 33, and at the same time, the gripping portion 3 is formed by cutting the reinforcing piece 3a from the belt-shaped roll film 39. Thereafter, the tubular film 1 is cut into a predetermined length to form the packaging bag A. Will be manufactured. In this case, the strip-shaped roll film 39 is cut by the perforated cutter 38 into the longitudinally broken line 3.
7, the longitudinal broken line 37 and the broken line portion 5a are displaced from each other so as to disperse the tensile load applied during the carrying. As described above, since the reinforcing piece 3a is provided to reinforce the gripping portion 3, when the gripping portion 3 is to be longitudinally cut, the reinforcing piece 3a also needs to be longitudinally cut at the same time. Since the vertical broken line 37 is also formed, the reinforcing piece 3a can be longitudinally cut along the vertical broken line 37. Therefore, while reinforcing the grip portion 3 with the reinforcing piece 3a,
This gripping part 3 can be longitudinally cut without difficulty.

In the packaging bag A, when the roll paper R is taken out, the cut-out dashed line 5 and the vertical dashed line 37 are cut open, whereby the gripping portion 3 including the reinforcing piece 3a is cut longitudinally and continuously. A cut is formed in the upper part of the bag body 4. And, as shown in FIG.
When the gripped portions 3, 3 cut vertically are opened by pulling them to both sides, the upper portion of the bag body 4 is opened right and left with this, and the opened portion can be used as an outlet for the roll paper R. it can. As described above, since the notch can be formed in the upper portion of the bag main body portion 4 continuously with the grip portion 3 in a longitudinal direction, the upper surface of the packaging bag A can be opened in a wide range. Therefore, the roll paper R
Can be taken out smoothly. In particular, in this embodiment, the cut broken line 5 is divided into two branch broken line portions 5b, 5b.
And the cut is formed in two places at distant positions on the bag body 4, so that the opening can be widened by the distance of the cut.

Further, since the cut dashed line 5 is branched into two in the middle of the grip portion 3, the boundary seal 2 remains in a bridge shape between the branched dashed lines 5b. Since the bridge seal portion 2a remains in a state in which the central portion of the opening is closed, it functions as a dust remover during storage until the roll paper R is completely removed. In this storage, it is preferable to close the opening by bringing the left and right grips 3, 3, which have been cut longitudinally, to the central portion in order to secure dust removal. When the packaging bag A is used as a garbage bag after use, the bridge seal portion 2a is torn and the opening is widened over the entire upper surface of the packaging bag A. There is no need to break the bridge seal portion 2a, and the bridge seal portion 2a can be simply broken by hand.

Next, FIG. 5 is a cutaway front view of a packaging bag according to a second embodiment. In this packaging bag B, one cut-off broken line 5 extends straight downward from the upper edge 30 of the grip portion 3, and extends from the grip portion 3 beyond the boundary seal portion 2 to the bag body portion 4.
Is formed so as to extend halfway.

FIG. 6 is a cutaway front view of a packaging bag according to a third embodiment. In this packaging bag C, the cut-off broken line 5 is formed by a single broken line portion 5 a extending downward from the upper edge 30 of the grip portion 3 to the boundary seal portion 2, and the tip of the broken line portion 5 is formed in the bag body portion 4. It is formed so as to be branched into the dashed branch portions 5b, 5b and to extend diagonally outward. In this packaging bag C, since the bridge seal portion 2a does not remain, the opening can be widened over the entire upper surface of the packaging bag C, and the garbage bag can be left as it is without tearing the bridge seal portion 2a. Can be used as

FIG. 7 is a cutaway front view of a packaging bag according to a fourth embodiment. In this packaging bag D, two cut-off broken lines 5, 5 extend downward from the upper edge 30 of the grip portion 3, extend beyond the boundary seal portion 2, and extend halfway through the bag body portion 4. In this packaging bag D, two cut broken lines 5,
5, the bridge seal portion 2a remains as in the first embodiment.

FIG. 8 shows a fifth embodiment of the present invention, and is a cutaway front view of a packaging bag. In this packaging bag E, two cut-away broken lines 5, 5 extend downward from the upper edge 30 of the grip portion 3, extend beyond the boundary seal portion 2, and extend halfway through the bag body portion 4. Then, in the bag body 4, the connecting cut-off broken line 5 c is connected so that both ends are continuous with the two cut-off broken lines 5, 5.
Are formed. In this packaging bag E, if the connecting cut-away broken line 5c is cut from the beginning together with the cut-away broken lines 5 and 5, the bridge seal portion 2a can be cut off.
The opening can be widened over the entire upper surface of the slab, and can be used as a garbage bag as it is without tearing the bridge seal portion 2a. Also, initially, the bridge cut-off dashed line 5c is left uncut, so that the bridge seal portion 2a is left. After the use of the roll paper R, the bridge cut-off dashed line 5c is cut off to cut off the bridge seal portion 2a. You may do so. In this way, it is possible to use the connection cut broken line 5c from the beginning and to cut it later according to the user's preference.

Next, FIG. 9 is a cutaway front view of a packaging bag according to a sixth embodiment. In this packaging bag F, two cut-off broken lines 5 and 5 are formed extending obliquely outward from the center of the upper edge 30 of the grip portion 3 and beyond the boundary seal portion 2 to the middle of the bag body portion 4. I have. As in the fifth embodiment, a connecting cut-off dashed line 5c is formed in the bag body 4 so that both ends are continuous with the two cut-off dashed lines 5,5. In this case, the broken broken line 5 is a short cut 5
1 is formed so as to extend linearly while maintaining the interval 52, and the direction of the cut 51 is formed in the vertical direction. That is, when a finger is inserted into the notches 34 for finger hanging and lifted, a vertical tensile load is applied to the packaging bag by the weight of the roll paper R. At this time, break 5
If 1 is formed in a direction (oblique direction) intersecting the vertical direction, the cut 51 may be torn by the tensile load, and the direction of the cut 51 is formed in the vertical direction to prevent this tear. . In addition, as a means for preventing tearing from the cut, the gap 52 between the cuts 51 may be widened.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this.
For example, the number of roll papers accommodated in the bag body is 1
In general, the number of stages is four or six, and these are stacked and packaged in two or three stages, but the present invention is not limited to this. Further, the cut-off broken line may be formed on the upper portion forming the upper surface of the bag main body in a state in which the roll paper is accommodated, and may be extended further downward. Further, the cut line of the cut broken line may be formed by machining such as a perforated cutter, or may be formed by thermal processing.

[0023]

As described above, in the packaging bag for roll paper according to the present invention, the grip portion is longitudinally cut by a broken line, and a cut is formed in the upper portion of the bag body continuously. Therefore, the outlet for the roll paper can be opened in a wide range on the upper surface of the packaging bag. Also, when using the used packaging bag as a garbage bag,
The effect is obtained that the seal portion remaining in the bridge shape can be easily torn, or the seal portion can be used as it is as a garbage bag without being torn. In addition, since the longitudinally broken line is formed on the reinforcing piece provided to reinforce the grip portion, the reinforcing piece can be longitudinally cut along the longitudinally broken line. Therefore, it is possible to easily longitudinally cut the grip portion while reinforcing the grip portion with the reinforcing piece. Further, when the positions of the cut dashed line of the gripping portion and the vertical broken line of the reinforcing piece are shifted, the tensile load applied during carrying can be dispersed, so that breakage of the bag can be prevented.
