However, the above-described conventional technology has the following problems.
In the container having the above-described conventional re-adhesive lid seal, the lid can be capped even after being opened once, and it is difficult to distinguish whether it is unopened or not. Therefore, in order to reveal that the lid seal has not been opened, a seal body called a virgin seal that is torn along with the peeling of the lid seal from the bag body is stuck across the boundary between the lid seal and the bag body surface. Is widely practiced. Thereby, it is an unopened mark that the virgin seal is not broken.
However, this virgin seal also requires material costs and manufacturing man-hours, and further has a burden of causing production loss due to failure to attach the virgin seal.

  The present invention has been made in view of the above problems in the prior art, and an object of the present invention is to add an unopened revealing function to a re-adhesive lid seal that covers an outlet for taking out the contents.

The invention according to claim 1 for solving the above-mentioned problems has a bag body having an accommodation space for a wet sheet therein and provided with an outlet for taking out the contained wet sheet;
A lid seal having an opening and closing portion that adheres to a peripheral portion of the outlet of the bag body in order to repeatedly close and open the outlet;
In a wet sheet container comprising:
The lid seal has an adjacent portion that is adjacent to the opening and closing portion and attached to the bag, and an easy tear portion that is formed at a boundary between the opening and closing portion and the adjacent portion.
The adjacent part adheres to the bag more strongly than the adhesive force of the opening / closing part to the bag,
The material of the lid seal is cut and opened at the easy tear portion as the adjacent portion is left attached to the bag body and the opening / closing portion is peeled off from the bag body. It is a wet sheet container.

  According to the first aspect of the present invention, unopened is revealed by the fact that the easy tearing portion at the boundary between the opening / closing portion and the adjacent portion of the lid seal is not cut.

  The invention according to claim 2 is the wet sheet container according to claim 1, wherein the adjacent portion extends along an edge of the outlet and adheres to the bag body. .

  According to the invention of claim 2, even when the opening / closing part of the lid seal is peeled from the bag body and the outlet is opened, the adjacent part is attached to the bag body extending along the edge of the outlet. Since it remains, this edge is reinforced, making it difficult to twist and sealing again without creating a gap between the bag body surface when the lid seal opening / closing part is attached to the peripheral edge of the outlet again. Becomes easier.

The invention described in claim 3 adheres to the peripheral portion of the outlet of the container in order to repeatedly close and open the outlet of the container provided with the outlet for taking out the contents. In lid seals with possible opening and closing parts,
An adjacent portion that is adjacent to the opening / closing portion and adheres to the container, and an easy tear portion formed at a boundary between the opening / closing portion and the adjacent portion,
The adjacent part has an adhesive layer having an adhesive force stronger than the adhesive force of the opening and closing part,
The lid seal material is cut at the easy tearing portion so that it can be opened when the opening / closing portion is peeled off from the housing while the adjacent portion remains attached to the housing. The lid seal is characterized.

  If the lid seal of the invention according to claim 3 is applied to the outlet of a container such as a bag body, unopened is revealed by the fact that the easy tearing portion at the boundary between the opening and closing portion of the lid seal and the adjacent portion is not cut. Is done.

  According to a fourth aspect of the present invention, in the lid seal according to the third aspect, the adjacent portion is formed to extend to a side portion of the opening / closing portion.

  If the lid seal of the invention according to claim 4 is applied to the outlet of the bag body, even when the opening / closing portion of the lid seal is peeled off from the bag body and the outlet is opened, the adjacent portion is removed along the edge of the outlet. Since this edge is reinforced, it becomes difficult to twist, and when the lid opening / closing part is attached to the peripheral part of the outlet again, It becomes easy to seal without generating a gap between them.

  According to the present invention, the virgin seal is abolished because an unopened revealing function is added to the re-adhesive lid seal that covers the outlet of the container such as a bag that contains the container such as a wet sheet. As a result, the cost associated with the virgin seal can be reduced and the production efficiency can be improved.

FIG. 6 is a plan view (a) and a plan view (b) in a half-open state of a lid seal according to another embodiment of the present invention.

  An embodiment of the present invention will be described below with reference to the drawings. The following is one embodiment of the present invention and does not limit the present invention.

A wet sheet container 1 according to an embodiment of the present invention includes a bag body 2 having a storage space for a wet sheet therein and provided with an outlet 2a for taking out the stored wet sheet, and an outlet 2a. In order to repeatedly close and open, the lid 2 is configured to include an opening / closing part 31 that adheres to the peripheral edge of the outlet 2a of the bag body 2 and can be re-adhered.
The bag body 2 is long in one direction and is formed in a rectangular shape in plan view. The outlet 2 a is formed on the surface 2 b of the bag body 2. The outlet 2a is formed in an oval shape that is long in the longitudinal direction of the bag body 2 and has rounded corners. A wet sheet such as a wet tissue containing alcohol or a liquid medicine is accommodated in the bag body 2.

The lid seal 3 is attached to the surface 2b of the bag body 2, and the opening / closing part 31 is arranged so as to cover the outlet 2a and its peripheral part. An adhesive layer is formed on the surface region of the opening / closing portion 31 that is aligned with the peripheral edge of the outlet 2a, and can be repeatedly peeled and re-adhered, and thus the outlet 2a can be repeatedly closed and opened.
The base end portion 32 and both side adjacent portions 34 and 35 of the lid seal 3 are attached to the surface 2 b of the bag body 2. The base end portion 32 is fixed with an adhesive or the like with a fixing force higher than the adhesive force of the opening / closing portion 31 so as not to be easily peeled off when the opening / closing portion 31 is peeled off.
The opening / closing part 31 is peeled off from the distal end part 33 opposite to the base end part 32. The tip 33 is provided with a knob 33a for the user to pick when the opening / closing part 31 is peeled off. The knob 33 a does not have an adhesive surface and does not adhere to the bag body 2. The knob portion 33a is formed to protrude outward at the tip portion 33, and is easy to float from the surface of the bag body 2, so that it is easy to pick.

The lid seal 3 has both side adjacent portions 34 and 35 adjoining the surface 2b of the bag body 2 adjacent to the opening / closing portion 31. Furthermore, the lid seal 3 has perforation lines 34a and 35a as easy tearing portions formed at the boundary between the opening / closing portion 31 and both side adjacent portions 34 and 35.
When opening the take-out port 2a, the user opens the take-out port 2a by picking the handle 33a by hand and peeling the opening / closing unit 31 away from the surface 2b of the bag body 2. The opening / closing part 31 can be peeled from the closed state of the outlet 2a in FIG. 3 (a) to the fully opened state in FIG. 3 (b).

When opening the outlet 2a for the first time from the unopened state, that is, when opening the user, the user picks the knob portion 33a by hand and peels the opening / closing portion 31 away from the surface 2b of the bag body 2, while on the other hand Both side adjacent portions 34 and 35 remain attached to the bag body 2. As the opening / closing portion 31 is peeled off from the bag body 2, the material of the lid seal 3 is cut and opened at the perforation lines 34 a and 35 a. Therefore, the both side adjacent portions 34 and 35 are fixed to the bag body 2 with an adhesive or the like with a fixing force that is at least enough to prevent the opening / closing portion 31 from peeling off from the bag body 2. The both side adjacent portions 34 and 35 adhere to the bag body 2 more strongly than the adhesive force of the opening and closing portion 31 to the bag body 2, and for this reason, the both sides adjacent portions 34 and 35 on the application surface of the lid seal 3 have an opening and closing portion. The adhesive layer which consists of an adhesive agent etc. which has stronger adhesive force than the adhesive force of the adhesion layer formed in the part of 31 is formed.
FIG. 4A shows the perforation lines 34a and 35a in the unopened state, and the portion e between the perforations m1 and m1 is connected. After opening, the cutting line d can be visually confirmed between the perforations m1, m1 as shown in FIG. 4 (b).
Therefore, if the cutting line d appears, it indicates that the package has been opened, and the cutting line d does not appear, that is, it is not cut along the perforation lines 34a, 35a.

In the perforation lines 34a and 35a shown in FIG. 4, since the cutting line d and the perforation m1 are in the same direction, there is a point that is difficult to visually confirm.
In order to make it easy to confirm the cutting line d, as shown in FIG. 5, it is possible to implement an embodiment in which an easy tear portion is formed by wedge-type perforations m2, m2, m2,. The wedge-type perforations m2, m2, m2,... Are connected with their tips oriented in the same direction, so that the lines connecting the tips of the wedge-type perforations m2, m2, m2,. The cut line d appears as shown in FIG. This makes it easier to determine whether it is unopened or opened.

When the opening / closing part 31 is peeled off at the time of opening and thereafter and the outlet 2a is opened, both side adjacent parts 34 and 35 remain attached to the surface 2b of the bag body 2 as shown in FIG. As shown in FIG. 3B, the both side adjacent portions 34 and 35 are attached to the edge portion along the longitudinal direction of the outlet 2a so as to extend in the longitudinal direction. Reinforced by the portions 34 and 35, it becomes difficult to twist, and when the opening / closing portion 31 of the lid seal 3 is again bonded to the peripheral portion of the outlet 2a, it is easy without causing a gap with the surface 2b of the bag body 2. Can be sealed.
The effect of reinforcing the outlet edge by the adjacent portion provided on the side portion of the opening / closing portion 31 is effective even if the adjacent portion is provided only on one side portion of the opening / closing portion. It is preferable to provide it. Even when the adjacent portion is provided only on one side of the opening / closing portion, the unopened revealing function is exhibited and the width of the opening / closing portion can be increased.

In addition, when not aiming at the reinforcement effect of the outlet edge part by such an adjacent part, as shown in FIG. 6, the lid seal 4 which provided the adjacent parts 44 and 45 in the corner | angular part is implemented. You can also
As shown in FIG. 6, the lid seal 4 includes an opening / closing part 41, a base end part 42, a knob part 43 a, both corner adjacent parts 44 and 45, and perforation lines 44 a and 45 a. Both corner adjacent portions 44 and 45 are provided at both corner portions adjacent to the knob portion 43a. The wedge-type perforation m2 described above may be applied to the perforation lines 44a and 45a.
According to the lid seal 4, there is no adjacent portion that remains in the bag body on both sides of the opening / closing portion 41, so the width of the opening / closing portion 41 is further increased compared to the case where the adjacent portion is provided only on one side portion described above. It can be taken big.
Moreover, even if an adjacent part is provided only in one corner | angular part, an unopened revealing function is exhibited.

  The material of the bag 2 is not particularly limited as long as it does not leak the liquid inside and does not react with the liquid component, but is preferably made of a thermoplastic resin such as polyethylene or polypropylene. In combination with a synthetic resin such as polyester and polyvinyl chloride, and a layer made of aluminum or the like. The shape of the outlet 2a provided on the upper surface of the bag body 2 can be any shape such as an ellipse, a circle, a square, or a shape with rounded square corners.

  The lid seals 3 and 4 are made of a single layer or a multilayer structure made of synthetic paper or synthetic resin such as polyethylene, polypropylene, or polyester. In particular, when a relatively stretchable synthetic resin such as unstretched polypropylene (CPP) is used, when the material is cut at the perforation line, the material between the perforations is stretched and cut by plastic deformation. Therefore, the cut surface can be roughened, and visual confirmation can be facilitated.

According to the wet sheet container described above, the virgin seal is abolished because an unopened display function is added to the re-adhesive lid seals 3 and 4 that cover the outlet 2a of the bag body 2 that accommodates the wet sheet. This can reduce the cost for the virgin seal and improve the production efficiency.
Of course, the unopened revealing function of the lid seal is effective even when the container is not a wet sheet and the container is not a bag.
