Abstract

PROBLEM TO BE SOLVED: To provide a package in which a closing lid can be easily opened, the closing lid is not closed by the repulsive force of a synthetic resin when a knob part is released from the hand after the closing lid was opened, and a wrinkle can be prevented from occurring when the package is re-sealed.SOLUTION: An opening/closing label 30A for covering an opening 22, through which wet tissue 11 is extracted, comprises: a knob part 32 disposed on one end side of a longitudinal direction; a body part 31; and a basement part 33 fixed on a packaging bag 20 by a first cut line 34 formed widthwise on the other end side of the longitudinal direction. Thus, the opening/closing label 30A is folded at the first cut line 34 and opened by pinching and peeling the knob part 32 on the one end side. The opening/closing label 30A has a construction, in which a surface resin layer 35, at least one intermediate resin layer 36, and a reverse face resin layer 37 are laminated in the recited order, and the reverse face resin layer 37 is formed with a second cut line 39A passing through at least the reverse face resin layer 37.

Description

  The present invention relates to a package that can accommodate a wet tissue and can be taken out from an opening, and can be resealed after being taken out.

Conventionally, for example, a packaging body that contains a wet tissue in which a fiber material is impregnated with a cleaning liquid such as alcohol or a lotion, is resealed after taking out the wet tissue, and is consumed repeatedly while preventing drying. (For example, refer to Patent Document 1).
As shown in FIG. 14, the package 100 described in Patent Document 1 includes an encapsulating bag 101 that is formed of a flexible sheet having air tightness and liquid tightness, and in which a wet tissue is enclosed. The enclosing bag 101 has a take-out port 102 for taking out the wet tissue and an open / close lid 103 covering the take-out port 102. The take-out port 102 is formed by cutting along a cutting notch 106 formed in the enclosing bag 101.

The wet tissue can be repeatedly taken out from the enclosing bag little by little without being consumed at once, and can be used. The open / close lid 103 can be resealed any number of times. The opening / closing lid 103 is formed separately from the enclosing bag 101 and is attached to the enclosing bag 101 with a pressure-sensitive adhesive so as to cover the take-out port 102.
The open / close lid 103 is provided with, for example, a semicircular knob 104 at both ends. Further, a notch 105 is provided on the inner side of the knob 104 in the opening / closing lid 103 over the entire width of the opening / closing lid 103.

Therefore, by picking the knob 104 at one end of the opening / closing lid 103 and opening the opening / closing lid 103 to the notch 105 at the other end, the take-out port 102 is exposed, so that the wet tissue can be taken out.
Further, after the wet tissue is taken out, the wet tissue can be prevented from being dried and stored by resealing it so as to cover the take-out port 102 with the opening / closing lid 103. By repeating this, the wet tissue can be taken out and used any number of times.

Japanese Patent No. 3182114 (FIG. 1)

In the conventional package as described above, an adhesive label made of a synthetic resin is usually used for the opening / closing lid. If the opening / closing lid does not have a certain degree of thickness and rigidity, when it is resealed after opening the opening / closing lid once, the opening / closing lid or the package becomes difficult to seal, so a label with higher rigidity is preferable.
However, when a highly rigid opening / closing lid is used, the repulsive force when opened is strong and the label tends to return more easily.
For this reason, when the hand is released from the knob after opening, there is a problem that the opening / closing lid is closed by the repulsive force of the synthetic resin and it is difficult to take out the wet tissue.
In addition, when a highly rigid opening / closing lid is used, there is a problem in that it is difficult to form a gap between the opening / closing lid and the enclosing bag and because the rigidity is high, it is difficult to open the opening / closing lid.

  The present invention has been made to solve the conventional problems, and can easily open and close the lid, and when the hand is released from the knob after opening the lid, the lid is opened and closed by the repulsive force of the synthetic resin. An object of the present invention is to provide a package that does not close the lid and can prevent wrinkles from occurring when resealed.

  (1) One aspect according to the present invention is a package having a packaging bag having an opening for storing a wet tissue and taking out the wet tissue, and an opening / closing label that is releasably bonded around the opening. The open / close label has a structure in which a front surface resin layer, at least one intermediate resin layer, and a back surface resin layer are laminated in this order, a knob portion provided on one end side in the longitudinal direction, a main body portion, A first cut line provided in the width direction on the other end side in the longitudinal direction and penetrating the intermediate resin layer and the back resin layer; a base portion fixed to the packaging bag by the first cut line; and a first cut line A package including a second cut line provided in the width direction on the side of the knob portion and penetrating at least the back surface resin layer is provided.

  (2) In the package of (1), the second score line penetrates the intermediate resin layer and the back surface resin layer and is formed at an interval of 0.5 mm to 2.0 mm from the first score line. It may be what was done.

  (3) Moreover, in the package of said (1), the 2nd cut line may penetrate the back surface resin layer, and may be formed in the boundary of a main-body part and a knob | pick part.

  (4) In the package of any one of (1) to (3), the surface resin layer may be formed from a polypropylene resin having a thickness of 15 μm or more and 30 μm or less.

  (5) Moreover, in the package of any one of (1) to (4), the intermediate resin layer and the back surface resin layer may have a total thickness of 80 μm or more and 300 μm or less.

  (6) In the package of any one of (1) to (5), the intermediate resin layer may have a thickness of at least one layer of 40 μm or more and 200 μm or less.

  In the present invention, the open / close label has a structure in which a front surface resin layer, at least one intermediate resin layer, and a back surface resin layer are laminated in this order, and is provided with a second score line penetrating at least the back surface resin layer. For this reason, since a back surface resin layer can be easily bent in a 2nd cut line, the packaging body which has the effect that an open / close label can be opened easily can be provided.

  Further, in the present invention, since the opening / closing label is easily folded and folded over by providing the second cut line, a rigid surface resin layer can be used, so that a more durable label and The package which has the effect that it can do can be provided.

(First embodiment)
Hereinafter, the packaging body of 1st Embodiment which concerns on this invention is demonstrated using drawing.
As shown in FIGS. 1 and 2, the packaging body 10 </ b> A according to the first embodiment of the present invention has a packaging bag 20 for storing the wet tissue 11.
The packaging bag 20 is formed in a flat cylindrical shape from a sheet having liquid tightness, air tightness, and the like, and is tightly joined (joined portion 21) at both ends in the longitudinal direction.
In addition, a gusset portion 202 is provided on the side surface of the packaging bag 20 so as to cope with a change in the thickness of the packaging bag 20.

The upper surface 201 of the packaging bag 20 is provided with an opening 22 for taking out the wet tissue 11 accommodated therein.
The opening 22 can be provided by cutting out the upper surface 201 of the packaging bag 20 from the beginning, but a cut 221 that can be easily cut out may be provided in the upper surface 201. When the cut 221 is provided, the opening 22 is formed by being cut when the opening / closing label 30A described later is first opened.

The shape of the opening 22 is not particularly limited. Here, a narrow oval opening 22 is provided.
Note that a reinforcing label 23 for reinforcing the periphery of the opening 22 can be provided on the upper surface 201 of the packaging bag 20. The reinforcing label 23 is provided with an opening 231 corresponding to the opening 22 of the upper surface 201 of the packaging bag 20. The reinforcing label 23 is preferably formed of PET (polyethylene terephthalate) resin having a thickness of 60 μm to 150 μm.
Thereby, wrinkles can be prevented from occurring around the opening 22 in the upper surface 201 of the packaging bag 20.

On the upper surface 201 of the packaging bag 20, a substantially rectangular or substantially elliptical opening / closing label 30 </ b> A covering the opening 22 is provided so as to be opened and closed.
2A and 3A, the opening / closing label 30A includes a main body 31 that covers the opening 22, a knob 32 provided on one end in the longitudinal direction, and the other end in the longitudinal direction. And a base portion 33 that supports the opening / closing label 30A during opening and closing.
Between the base part 33 and the main-body part 31, the 1st cut line 34 is provided in the width direction of the opening / closing label 30A.

As shown in FIG. 3B, the opening / closing label 30A is formed by laminating a front surface resin layer 35 and a back surface resin layer 37. Between the front surface resin layer 35 and the back surface resin layer 37, at least one intermediate resin layer 36 (here, the case of one layer is illustrated) is provided. An adhesive layer 38 (381) is provided between the layers and on the inner surface of the back surface resin layer 37. As a method for laminating the front surface resin layer 35, the intermediate resin layer 36, and the back surface resin layer 37, a method by co-extrusion, a method of bonding together with an adhesive, or the like can be used. From the viewpoint of cost and productivity, a method of bonding through an adhesive is preferable.
A first cut line 34 is provided between the base portion 33 and the main body portion 31. The first score line 34 is provided except for the front surface resin layer 35, and is provided through the intermediate resin layer 36, the back surface resin layer 37, and the adhesive layer 38.

The adhesive layer 381 applied to the inner surface of the back surface resin layer 37 is formed of an adhesive that can be peeled off from the upper surface 201 of the packaging bag 20. Thereby, the opening / closing label 30 </ b> A is detachably bonded to the upper surface 201 of the packaging bag 20.
Note that the adhesive layer 381 is not provided on the inner surface of the knob 32 in the back surface resin layer 37. For this reason, since the knob | pick part 32 is not adhere | attached on the upper surface 201 of the packaging bag 20, it can lift easily.

The surface resin layer 35 is desirably formed of a polypropylene resin having a thickness of 15 μm or more and 30 μm or less. Furthermore, it is more desirable that the thickness is 20 μm.
If the thickness is less than 15 μm, breakage tends to occur at a position corresponding to the first cut line 34 that is a connecting portion during repeated opening and closing. On the other hand, if the thickness is greater than 30 μm, the repulsive force of the surface resin layer 35 is increased, and the opening / closing label 30A may be returned by the repulsive force when the knob 32 is released at the time of opening.

The length of the connection portion, that is, the width direction length (connection width) b (see FIG. 3A) of the opening / closing label 30A in the base portion 33 is preferably 15 mm or more and 70 mm or less.
If the connection width is narrower than 15 mm, the strength is weak, and if it is larger than 70 mm, the repulsion by the surface resin layer 35 is too strong.

The total thickness of the intermediate resin layer 36 and the back resin layer 37 is preferably 80 μm or more and 300 μm or less. Furthermore, it is more desirable that it is 150 μm or more and 250 μm or less.
When the total thickness is less than 80 μm, the rigidity of the entire opening / closing label 30A is low, and it is easy to bend and difficult to open and close. On the other hand, if the thickness is 300 μm or more, the thickness becomes more than necessary, resulting in wasted material.

It is desirable that at least one of the intermediate resin layers 36 is formed of a resin layer having a thickness of 40 μm or more and 200 μm or less. Furthermore, it is more desirable that the thickness is 80 μm or more and 150 μm or less.
The intermediate resin layer 36 desirably has higher rigidity than the back surface resin layer 37. This is because when the back surface resin layer 37 has higher rigidity than the intermediate resin layer 36, delamination (delamination) is likely to occur between the layers.

As shown in FIGS. 1 to 3, a second cut line 39 </ b> A is provided in parallel to the first cut line 34 on the side of the knob 32 from the first cut line 34.
The second score line 39 </ b> A is provided through the intermediate resin layer 36 and the back surface resin layer 37.
That is, since the first cut line 34 and the second cut line 39A are not provided in the surface resin layer 35, they are continuous and have a constant rigidity.

The second cut lines 39A are preferably formed in parallel with the first cut lines 34 at intervals of 0.5 mm or more and 2.0 mm or less.
FIG. 4 shows a state in which the opening / closing label 30A is opened. When the opening / closing label 30 </ b> A is opened, the opening / closing label 30 </ b> A is bent upward from the first cut line 34 provided at one end of the base portion 33 fixed to the upper surface 201 of the packaging bag 20. At this time, since only the front surface resin layer 35 is continuous, the back surface resin layer 37 and the intermediate resin layer 36 are cut at the first cut line 34, or at least the rigidity is greatly reduced. Bend to.
Furthermore, similarly, since only the surface resin layer 35 is continuous in the second cut line 39A, it is easily bent.
Thereby, the opening / closing label 30 </ b> A can be easily opened and closed, and is not easily closed only by the repulsive force of the surface resin layer 35.

Next, the effect of the package 10A of the present invention will be described.
The package 10 </ b> A of the present invention includes a packaging bag 20 having an opening 22 for storing the wet tissue 11 and taking out the wet tissue 11, and an opening / closing label 30 </ b> A covering the opening 22. The opening / closing label 30 </ b> A includes a knob portion 32 provided on one end side in the longitudinal direction, a main body portion 31, and a base portion 33 that is fixed to the packaging bag 20 and supports the opening / closing label 30 </ b> A. Between the base part 33 and the main-body part 31, the 1st cut line 34 is provided in the width direction of the opening / closing label 30A.

Therefore, the opening / closing label 30A is bent at the first cut line 34 by opening the opening / closing label 30A and then removing the main body 31 of the opening / closing label 30A. Thereby, since the opening part 22 is exposed, the wet tissue 11 can be taken out.
Further, when the opening / closing label 30A is opened, it is bent at the first cut line 34 due to the weight of the opening / closing label 30A, so that the open state is maintained. For this reason, even if the hand is released from the knob 32, the opening / closing label 30A does not return due to the repulsive force, so that the wet tissue 11 can be easily taken out.

Further, in the package 10A of the present invention, the second cut lines 39A are formed at intervals of 0.5 mm or more and 2.0 mm or less from the first cut lines 34.
For this reason, the cooperation of the first cut line 34 and the second cut line 39A allows the opening / closing label 30A to be easily folded and opened, and the repulsive force to return after opening is small. It becomes difficult to return even if you let go.
Thereby, the wet tissue 11 can be taken out easily.
Further, since the surface resin layer 35 having a certain degree of rigidity can be used, the durability of the opening / closing label 30A can be improved.

Further, in the package 10A of the present invention, the surface resin layer 35 was formed from a polypropylene resin having a thickness of 15 μm or more and 30 μm or less.
If the surface resin layer 35 is thicker than 30 μm, the repulsive force at the root portion is increased, and the opening / closing label 30 </ b> A is easily closed when the hand is released from the knob 32, making it difficult to remove the wet tissue 11.
On the other hand, if the thickness is less than 15 μm, the repulsive force at the base portion is small, and it tends to break when repeatedly opened and closed.

Further, in the package 10A of the present invention, the total thickness of the intermediate resin layer 36 and the back surface resin layer 37 is set to be 80 μm or more and 300 μm or less.
Thereby, the rigidity of the entire opening / closing label 30A can be sufficiently secured, and it is possible to prevent the opening / closing label 30A from being swung.
Moreover, since it is not too thick, waste of material can be prevented.

Furthermore, in the package 10A of the present invention, at least one layer of the intermediate resin layer 36 is formed from a resin having a thickness of 40 μm or more and 200 μm or less.
Thereby, the opening / closing label 30A can ensure a suitable rigidity. As the base material for the intermediate resin layer, a thermoplastic resin is desirable, and a polyethylene terephthalate resin is more desirable.

Note that the package 10A of the first embodiment according to the present invention can be appropriately modified and improved.
For example, in the packaging body 10A described above, the case where the reinforcing label 23 is provided on the upper surface 201 of the packaging bag 20 is illustrated, but the reinforcing label 23 is provided on the inner surface of the packaging bag 20 as shown in FIG. Is also possible.
Even if it does in this way, it can prevent that a wrinkle generate | occur | produces around the opening part 22 in the upper surface 201 of the packaging bag 20 at the time of opening and closing of the opening / closing label 30A.
Moreover, since the opening / closing label 30A can be easily bent at the first cut line 34 and the second cut line 39A, the open / close label 30A can be easily opened and closed.

Moreover, as shown in FIG. 6, when the opening / closing label 30A is opened, the outer frame portion 40 remaining in the package 10A can be provided integrally with the opening / closing label 30A. That is, the outer frame portion 40 is a remaining portion obtained by cutting out the main body portion 31 and the knob portion 32 of the opening / closing label 30 </ b> A, and the base portion 33 is also the outer frame portion 40.
Thereby, at the time of opening and closing of the opening and closing label 30A, the upper surface 201 of the packaging bag 20 is less likely to be wrinkled, and the opening and closing label 30A can be opened and closed smoothly.
Moreover, since the back surface resin layer 37 can be easily bent at the first cut line 34 and the second cut line 39A, the open / close label 30A can be easily opened.

Furthermore, as shown in FIG. 7, curved stoppers can be formed in the vicinity of the first cut line 34 and the second cut line 39A.
FIG. 7A shows a case where the stopper 41A is provided in the above-described package 10A, and a curved cut 42A is provided in the main body portion 31 continuously to the first cut line 34. FIG.
FIG. 7B shows a case in which the stopper 41B is provided when the outer frame portion 40 is provided (see FIG. 6), and a curved cut 42B is provided in the outer frame portion 40 continuously to the first cut line 34. It was.
Thereby, even when the opening / closing label 30 </ b> A is vigorously opened, it can be reliably folded back along the first cut line 34.

(Second Embodiment)
Next, the packaging body of 2nd Embodiment which concerns on this invention is demonstrated.
In addition, suppose that the same code | symbol is attached | subjected to the site | part common to 10 A of package bodies which concern on 1st Embodiment mentioned above, and the overlapping description is abbreviate | omitted.
As shown in FIG.8 and FIG.9, in the package 10B of 2nd Embodiment, the 2nd cut line 39B was formed in the boundary of the main-body part 31 and the knob | pick part 32 in the opening / closing label 30B.

As shown in FIG. 10B, the second cut line 39B is provided through the back surface resin layer 37. Further, the adhesive layer 381 is not applied to the knob 32 in the back surface resin layer 37.
For this reason, the knob | pick part 32 can be easily bent in the 2nd cut line 39B. Further, since the knob portion 32 is not provided with the adhesive layer 381, the knob portion 32 can be easily picked and the opening / closing label 30B can be easily opened.

  When the second cut line 39B of the knob 32 is formed so as to penetrate to the intermediate resin layer 36, the breakage occurs between the surface resin layer 35 and the intermediate resin layer 36 when the opening / closing label 30B is opened. And easily cause delamination.

(Example)
Hereinafter, the present invention will be described specifically by way of examples. However, this invention is not restrict | limited at all by these Examples. Evaluation of the packaging bodies obtained in Examples and Comparative Examples was performed as follows. For any of the evaluation methods, a four-step evaluation was performed in the order of high evaluation: ◎, ○, Δ, ×.

<Rigidity of the open / close label>
The rigidity of the open / close label was evaluated based on the ease of wrinkling on the label due to the lack of rigidity when the label was actually opened and closed.

<Rebound and return of opening / closing label>
The rebound return of the open / close label was evaluated by whether or not the label naturally returned due to the repulsion of the synthetic resin when the hand was released from the picking portion 32 after the label was actually opened.

<Ease of picking open / close labels>
The ease of picking the open / close label was evaluated by conducting a questionnaire survey for practical use.

<Delamination of each layer of the open / close label>
The delamination of the open / close label was repeatedly opened and closed over 20 times, and it was visually evaluated whether delamination (delamination) occurred between the layers.

  In Example 1, PP (polypropylene) resin having a thickness of 20 μm was used for the surface resin layer 35. The intermediate resin layer 36 is a single layer, and a PET (polyethylene terephthalate) resin having a thickness of 120 μm was used. A PP resin with a thickness of 100 μm was used for the back surface resin layer 37. Moreover, the 1st cut line 34 and the 2nd cut line 39B were provided. Each layer was adhered with an adhesive, and an adhesive layer 381 was provided on the back surface resin layer 37 to produce an opening / closing label 30B, which was used to obtain a package. Table 1 shows the configuration of each layer (material, thickness, presence or absence of score lines) and evaluation results. As a result of Example 1, there was no problem with the rigidity and rebound of the opening / closing label 30B and delamination between the respective layers, and a good effect was obtained with respect to the ease of picking the opening / closing label 30B.

  In Example 2, two intermediate resin layers 36 were provided. Table 1 shows the configuration of each layer (material, thickness, presence or absence of score lines) and evaluation results. As a result of Example 2, good effects were obtained with respect to the rigidity and rebound of the opening / closing label 30B, the ease of picking the opening / closing label 30B, and the delamination between the layers.

  In Example 3, two intermediate resin layers 36 thicker than the intermediate resin layer 36 of Example 2 were provided. Table 1 shows the configuration of each layer (material, thickness, presence or absence of score lines) and evaluation results. The result of Example 3 was slightly inferior to that of Example 2 in the rebound return of the open / close label 30B and the ease of picking.

  In Example 4, the surface resin layer 35 was formed of 20 μm thick PP resin, the intermediate resin layer 36 was formed of 60 μm thick PP resin, and the back surface resin layer 37 was formed of 150 μm thick highly rigid PET resin. . Table 1 shows the configuration of each layer (material, thickness, presence or absence of score lines) and evaluation results. As a result of Example 4, the ease of picking of the opening / closing label 30B was good, but some delamination occurred.

  In the comparative example, the first cut line 34 and the second cut line 39B were not formed, and two intermediate resin layers 36 were provided. Table 1 shows the configuration of each layer (material, thickness, presence or absence of score lines) and evaluation results. As a result of the comparative example, the opening / closing label 30 </ b> B was repelled and not easily picked.

As described above, according to the package 10B of the second embodiment described above, the second cut line 39B is formed at the boundary between the main body 31 and the knob 32 of the opening / closing label 30B.
For this reason, since the knob | pick part 32 bends easily with respect to the main-body part 31, when opening the opening / closing label 30B, the knob | pick part 32 can be easily picked and the opening / closing label 30B can be opened easily.

Note that the package 10B according to the second embodiment of the present invention can be appropriately modified and improved.
For example, in the packaging body 10B described above, the case where the reinforcing label 23 is provided on the upper surface 201 of the packaging bag 20 is illustrated, but the reinforcing label 23 is provided on the inner surface of the packaging bag 20 as shown in FIG. Is also possible.
Even if it does in this way, it can prevent that a wrinkle generate | occur | produces around the opening part 22 in the upper surface 201 of the packaging bag 20 at the time of opening and closing of the opening / closing label 30B.
Moreover, since the knob | pick part 32 can be bent easily in the 2nd cut line 39B, the knob | pick part 32 can be easily picked and the opening / closing label 30B can be opened easily.

Further, as shown in FIG. 12, it is possible to integrally provide the outer frame portion 40 remaining in the package 10B on the opening / closing label 30B when the opening / closing label 30B is opened. That is, the outer frame portion 40 is a remaining portion obtained by cutting out the main body portion 31 and the knob portion 32 of the opening / closing label 30B, and the base portion 33 is also the outer frame portion 40.
Thereby, when opening / closing the opening / closing label 30B, the upper surface 201 of the packaging bag 20 is less likely to be wrinkled, and the opening / closing label 30B can be opened and closed smoothly.
Moreover, since the knob | pick part 32 can be bent easily in the 2nd cut line 39B, the knob | pick part 32 can be easily picked and the opening / closing label 30B can be opened easily.

Further, as shown in FIG. 13, a curved stopper can be formed in the vicinity of the first cut line 34.
FIG. 13A shows a case where the stopper 41A is provided in the packaging body 10B described above, and a curved cut 42A is provided in the main body 31 continuously to the first cut line 34. FIG.
FIG. 13B shows a case where the stopper 41B is provided when the outer frame portion 40 is provided (see FIG. 12), and a curved cut 42B is provided in the outer frame portion 40 continuously to the first cut line 34. It was.
Thereby, even when the opening / closing label 30B is opened with force, it can be reliably folded back along the first cut line 34.

The package of the present invention is not limited to the above-described embodiments, and appropriate modifications and improvements can be made.
