Description

  The present invention relates to a refill bag containing liquid detergent or the like.

  For example, in the field of liquid detergent used in a bottle equipped with an applicator for application to a clothing collar, the liquid detergent is put in a refill bag and sold, and the bottle is refilled and used. Conventionally known.

  In such a refill bag, when the liquid detergent as the contents is refilled into the bottle, it is preferable to provide a small spout for easily and reliably injecting the liquid detergent from the mouth of the bottle.

On the other hand, due to the problem of garbage disposal, the refill bag after all the liquid detergent has been poured into the bottle needs to be washed away with water before it is discarded. Sometimes.
In that case, injecting water from the small spout for refilling the bottle to wash away the remaining liquid is inferior in workability. In addition, liquid detergent compositions containing surfactants are easy to foam when the remaining liquid is washed away, difficult to wash, and when the liquid detergent composition adheres to the hand, the hands become sticky, and even after washing, the hand smells. There was a problem of remaining. Therefore, it is preferable to provide another large opening and wash away the remaining liquid using this.

An example of a refill bag (pouch) having such a configuration is disclosed in Patent Document 1. FIG. 1 shows a refill bag disclosed in Patent Document 1. The refill bag 10 is formed into a hollow bag shape by stacking two sheet materials and sealing the entire periphery thereof.
By breaking the broken line 11, a small spout is formed, and the liquid detergent or the like as the contents can be transferred from here to another bottle (not shown). Moreover, when washing away the remaining liquid before discarding the bag, a large opening can be formed by breaking the broken line 12.

JP 2004-43000 A

However, in the refill bag 10 shown in FIG. 1, since the two break lines 11 and the break line 12 can be opened in any order, the break line 12 may be unintentionally opened first.
In that case, it is difficult to perform the operation of pouring the liquid detergent into the mouth of the bottle, and the detergent may spill.

  Accordingly, an object of the present invention is to provide a refill bag that can be easily transferred to a bottle and cleaned inside, and that does not accidentally form a large opening for internal cleaning. Is to provide.

The present invention has been made in order to effectively solve the above problems, and provides a refill bag having the following features.
That is, the refill bag of the present invention is a refill bag configured by sealing the periphery of two opposing sheet materials, and is “a first break line that is broken to form a refill opening. And “a second break line that is broken to form an opening for internal cleaning” and “a guide line that extends from the first break line to the second break line in the peripheral seal region”.
And the 2nd fracture line has a starting point in the position which put the fixed distance from the outer edge within the circumference seal field.

In the present invention, the “breaking line” means a “linear portion having a low breaking strength” that extends along the line when it is desired to break the sheet material along a desired line. Illustratively, it is as follows, but is not limited thereto.
For example, when the sheet material has a laminated structure, a “break line” can be obtained by breaking one of the sheets along the line. Moreover, it can also be set as a "break line" by irradiating a laser beam to a sheet material, and cutting a part of the thickness width, without penetrating the said sheet material. Furthermore, if a sheet material having “tearability” that can be easily torn only in a specific direction (tear direction) is used, a “break line” is formed by bringing the tear direction along the line to be broken. be able to.

Further, in the present invention, the “guide line” is a linear portion for guiding a break that proceeds on the first break line toward the second break line. Illustratively, it is as follows, but is not limited thereto.
For example, a cut line that penetrates the peripheral seal region, a perforation formed in the peripheral seal region, a half-cut line, or the like can be used as the “guide line”.

  In the refill bag of the present invention having the above-described configuration, the starting point of the second break line is located at a position away from the outer edge in the peripheral seal region. That is, the starting point does not reach the outermost edge of the bag. Therefore, the second break line can only be started after the first break line is broken (thus forming a refilling opening) and the starting point is located at the outer peripheral edge. That is, it is unlikely that the second cleaning line is broken by mistake and the internal cleaning opening is formed before the refilling opening is formed.

  Moreover, since the 1st broken line and the 2nd broken line are connected via the guide line, an appropriate distance can be put between the 1st broken line and the 2nd broken line. In such a case, when the consumer tries to break the second break line, the contents such as the detergent attached to the area near the first break line that has already been broken adhere to the consumer's hand and are opened. It can be prevented from becoming staggered (soiled hands).

  Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 2 shows a refill bag 20 according to the first embodiment of the present invention.

≪First breaking line 21≫
The refill bag 20 is configured in a bag shape by sealing the periphery of two opposing sheet materials. A region 30 indicated by hatching in the drawing is a surrounding seal region.
The first break line 21 extends from the recessed portion 31 to the recessed portion 32 on the peripheral seal region 30 so as to cross the corner portion of the bag, and a refilling opening is formed by breaking the first broken line 21. The first break line 21 is formed on both of the two opposing sheet materials.
FIG. 3 shows a state after the first break line 21 is broken. The contents can be transferred from the refill opening thus formed to a bottle (not shown) or the like.

≪Second breaking line 22≫
The second break line 22 extends from the recess 32 on the peripheral seal region 30 in the lateral direction (that is, the width direction of the bag). The 2nd breaking line 22 is for forming the opening for internal washing larger than the said opening for refilling by breaking this.
That is, after all the contents are transferred to another bottle or the like, before the refill bag 20 is discarded, the second break line 22 is broken to form a large opening (internal cleaning opening), Wash out any residue using the cleaning opening.
The second break line 22 is also formed on both of the two opposing sheet materials. The second breaking line 22 has a starting point 22a at a position in the peripheral seal region 30 at a certain distance from the outer edge thereof. In other words, the starting point 22a does not reach the outermost edge of the bag.
Further, the second break line 22 has an end point 22 b on the inner side of the surrounding seal region 30. That is, the end point 22b does not reach the surrounding seal region 30 (see FIG. 2).

≪Guide line 25≫
In the refill bag of the present invention, a guide line 25 extending from the first break line 21 to the second break line 22 is provided on the peripheral seal region 30. In the example shown in FIGS. 2 and 3, the guide line 25 is formed by a cut line that penetrates the peripheral seal region 30.
Further, the guide line 25 has a V-shape that is pointed toward the inner side of the bag in the vicinity of the second break line 22. And the starting point 22a of the 2nd fracture | rupture line 22 has rested on the vertex of the said V shape.
As a result, after the corner portion 20a is separated, the outer edge shape of the peripheral seal region 30 in the vicinity of the start point 22a of the second fracture line 22 becomes a notch shape recessed toward the start point 22a. Thereby, the opening start operation | work of the 2nd broken line 22 becomes easy.

≪Action≫
The procedure for actually opening the refill bag 20 described above and the operation of each line in that case will be described below.

  When the first break line 21 is broken from the start point 21a toward the end point 21b, the intersection of the first break line 21 and the guide line 25 is reached on the recess 32 of the peripheral seal region 30 (note that the guide line The starting point 25a of 25 may be slightly away from the first break line 21). Since the guide line 25 is constituted by a cut line that penetrates the peripheral seal region 30, the breakage proceeds from the guide line 25 and finally the corner portion 20a of the bag is separated from the bag (see FIG. 3). In order to ensure this, the end point 25b of the guide wire 25 is preferably terminated toward the outside of the bag.

The starting point 22 a of the second break line 22 is on the guide line 25. For this reason, as shown in FIG. 3, the start point 22a exists on the outer peripheral edge of the bag only after the corner portion 20a is separated from the bag body.
That is, by breaking the first break line 22 (this forms a refill opening), the starting point 22a is located at the outer peripheral edge of the bag, and for this reason, the second break line 22 is only begun to break. be able to. Therefore, it is unlikely that the second cleaning line 22 is accidentally broken to form the internal cleaning opening before the refilling opening is formed.

  As shown in FIG. 2, the second fracture line 22 does not reach the peripheral seal region 30 and has an end point 22 b on the inner side of the peripheral seal region 30. If comprised in this way, even when the 2nd fracture | rupture line 22 is broken and the opening for internal washing | cleaning is formed, the part above the 2nd fracture | rupture line 22 will not isolate | separate from a bag main body, but it is convenient on disposal.

≪Another example of guide line 25≫
In the example shown in FIGS. 2 and 3, since the guide line 25 is formed by a cut line, the break that proceeds on the first break line 21 is reliably transferred from the first break line 21 to the guide line 25. It changes and advances on the guide line 25.
However, the guide line 25 does not necessarily need to be formed by a cut line, and may be formed by a perforation or a half cut line. In that case, it is preferable to set the breaking strength of the guide wire 25 to be weaker than that of the first breaking line 21. As a result, the break progressing along the first break line 21 is smoothly transferred onto the guide line 25.

  In addition, the above guide line 25 can be formed by irradiating the surrounding seal region 30 with a laser beam.

<< Another Example of Second Break Line 22 >>
In the example shown in FIGS. 2 and 3, the starting point of the second break line 22 is on the guide line 25. However, in the present invention, it is sufficient that the starting point 22a of the second break line 22 is located at the outer peripheral edge of the bag only after the first break line 21 is broken. Therefore, the starting point 22 a of the second break line 22 may exist at a position away from the guide line 25.
In other words, it is sufficient that the starting point 22a does not reach the outermost edge of the bag before breaking the first break line 21. That is, it suffices if the starting point 22a exists at a position in the peripheral seal region 30 at a certain distance from the outer edge.

≪Configuration in which the second break line is a cut line in the vicinity of the start point (FIG. 4) ≫
FIG. 4 is an enlarged view of a main part showing another example of the refill bag, and shows an enlarged portion near the recess 32 in the peripheral seal region 30 in FIG. 2.
In the example of FIG. 4, the second break line 22 is configured as a cut line 35 that penetrates the peripheral seal region 30 in a region near the starting point 22 a. Thereby, the opening start operation | work of the 2nd broken line 22 becomes easy.
Of course, this score line 35 extends only within the peripheral seal region 30.

≪Configuration in which the guide line and the second break line are connected via the easy break area (FIG. 5) >>
FIG. 5 is an enlarged view of a main part showing still another example of the refill bag, and shows an enlarged portion near the recess 32 of the peripheral seal region 30 in FIG.
In the example of FIG. 5, the guide wire 25 and the second break line 22 are connected via the easy break region 40. The easily breakable region 40 is obtained by, for example, irradiating a certain region in the peripheral seal region 30 with a laser to reduce the strength of the region.
When the positions of the guide line 25 and the second break line 22 are shifted, the position shift can be absorbed by connecting the two with such an easily breakable region 40.

≪Explanation of layer structure≫
As the sheet material constituting the refill bag, one having a laminated structure is preferably adopted. In that case, the laminated structure is not limited to a specific one, but some will be described as an example.
From the outer surface side of the bag toward the inner side,
(1) Laminated structure of “ base layer / printing layer / adhesive layer / thermoadhesive resin layer”.
(2) Laminated structure of “base material layer / printing layer / adhesive layer / base material layer / thermoadhesive resin layer”.
In addition, it is preferable to omit the printing layer in the laminated structure at a position where the first break line 21, the second break line 22, and the guide line 25 are provided. Since the breaking strength of the sheet material is weakened at the portion where the printing layer is omitted, the consumer can easily break it.

Here, as the base material layer, an ON film (biaxially stretched nylon), a PET film (biaxially stretched polyethylene terephthalate), and other appropriate ones can be used.
As the heat-adhesive resin layer, LLDPE (linear low density polyethylene) and other appropriate ones can be used.
Moreover, it is preferable to laminate | stack by a dry lamination (DL) method, using a urethane type adhesive as an adhesive layer.

Note that the first break line 21 and the second break line 22 may be “linear portions with low break strength” provided in the sheet material, and therefore when the sheet material has the above-described laminated structure, By breaking one layer (for example, an underlined layer), a “break line” can be obtained.
The first break line 21 and the second break line 22 may be configured by irradiating the sheet material with a laser beam and cutting a part of the thickness width without penetrating the sheet material.
Furthermore, if a sheet material having “tearability” that can be easily torn only in a specific direction (tear direction) is used, a “break line” is formed by bringing the tear direction along the line to be broken. be able to. In general, since a uniaxially stretched film has “tearability” in the stretching direction, it can be used as a “breaking line”.

≪Another example of refill bag≫
FIG. 6 shows another example of the refill bag of the present invention. The sheet material constituting the refill bag 50 has a laminated structure of “base layer / printing layer / adhesive layer / thermoadhesive resin layer” in order from the outer surface side to the inner side of the bag. Two such sheet materials are stacked opposite to each other, and the periphery thereof is sealed.
An ON film (biaxially stretched nylon) is used as the base material layer, and an LLDPE film (linear low density polyethylene) is used as the thermal adhesive resin layer. Further, an urethane film is used as an adhesive layer, and an ON film having a printed layer on the back surface and an LLDPE film are laminated by a dry lamination (DL) method.

  In FIG. 6, the upper side 50a of the refill bag 50 is not yet sealed. In the stage of manufacturing the refill bag, contents such as liquid detergent are put from the unsealed upper side portion. Finally, the upper side portion is also sealed and shipped as a final product.

  In FIG. 6, reference numeral 56 indicates a raised portion provided on the sheet material. The raised portions 56 are formed on both of the two sheets facing each other, and each protrudes toward the outside of the bag. The raised portion 56 constitutes a spout when the first break line 51 is broken. Of course, even if such a raised portion 56 does not exist, the spout is formed by breaking the first break line 51.

  In FIG. 6, reference numeral 59 indicates a bottom material. That is, the periphery of the bag is sealed after the folded bottom material 59 is sandwiched between two sheet materials. Thereby, the refill bag 50 is configured as a stand-pack with self-supporting property.

  In the refill bag 50 of FIG. 6, five first break lines 51 for forming the refill openings are formed in parallel, and the five first break lines are the end edges of the peripheral seal region 58. I-shaped cuts penetrating in the line region are formed, and the five first break lines relax the positional deviation from the I-shaped cuts. Further, the second break line 52 for forming the internal cleaning opening extends in the lateral direction in parallel with the upper side 50a of the bag. Of course, other configurations may be employed. The first break line 51 and the second break line 52 are both formed by cutting portions of the base material layer and the printed layer with a laser beam and weakening the break strength.

A portion of the second break line 52 in the vicinity of the start point 52a is formed as a cut line 53 that penetrates the peripheral seal region 58 to facilitate the opening start operation. The score line 53 extends only within the peripheral seal region 58.
Further, since the end point 52b of the second break line 52 is located on the inner side of the surrounding seal region 58, even when the second break line 52 is broken to form the internal cleaning opening, the second break line 52 is formed. The upper part is not separated from the bag body, which is convenient for disposal.

  The guide line 55 is formed as a cut line that penetrates the peripheral seal region 58. Therefore, the break that proceeds along the first break line 51 is reliably transferred onto the guide line 55. The guide line 55 is formed by penetrating the bag when the peripheral edge of the peripheral seal portion is cut with a punching blade, and the notch 53 is formed by irradiating the peripheral seal region 58 with a laser beam.

  Although not shown in the drawing, an arrow indicating the breaking direction, a number indicating the breaking order, etc. may be displayed along the first breaking line 51 and the second breaking line 52 for the convenience of the consumer. it can. Indications such as arrows and numbers are provided on the printed layer.
