Description

Description: TECHNICAL FIELD The present invention relates to an encapsulating material, and in particular, for accommodating and protecting a storage item such as a delivery note and a slip attached to, for example, a delivery item. Encapsulation material.

(Prior Art) Conventionally, an adhesive bag body for storing and protecting this type of storage item is shown in Japanese Utility Model Publication No. 50-17356. This adhesive bag body has an adhesive adhesive layer formed on the lower surface of one bag portion.

(Problems to be Solved by the Invention) In such an adhesive bag body, since the bag portion is open, the stored items may fall out.

Therefore, a main object of the present invention is to provide a novel encapsulating material which can relatively easily form a bag portion only by pasting and can seal the bag portion.

(Means for Solving the Problem) The present invention relates to a base material, a sticking adhesive layer formed on one main surface of the base material, a release paper temporarily attached to the sticking adhesive layer, and a release paper. Is a first cut line formed from one end to the other end and a second cut line formed so as to be connected to two places of the first cut line.

(Operation) The release paper can peel off the portion outside the second cut, thereby exposing the sticking adhesive layer. Then, the bag can be formed between the base material and the surface of the delivered product by adhering the base material with the exposed adhesive layer to the surface of the delivered product, for example.

In addition, in the bag portion formed between the base material and the surface of the delivered product,
The storage is placed through the first cut.

Furthermore, the release paper can be peeled off the outer portion of the first cut, and when the part of the base material is adhered to the surface of the product by the adhesive adhesive layer exposed thereby, the bag part is sealed. To be done.

(Effect of the Invention) According to the present invention, an encapsulating material can be obtained in which the bag portion can be formed relatively easily by simply pasting and the bag portion can be sealed.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

(Embodiment) FIG. 1A is an exploded perspective view showing an embodiment of the present invention.
1B is a perspective view thereof, and FIG. 1C is a perspective view thereof.
FIG. 1B is a cross-sectional view taken along the line IC-IC of FIG. 1B.

The encapsulating material 10 of this embodiment includes a rectangular base material 12, for example. The base material 12 is formed of, for example, thermosensitive color recording paper. A sticking adhesive layer 14 made of an adhesive such as a pressure-sensitive adhesive is formed on one main surface of the substrate 12. A rectangular release paper 16 made of, for example, paper and a synthetic resin sheet is temporarily attached to the surface of the sticking adhesive layer 14. A release agent layer made of a release agent such as silicon is formed on the surface of the release paper 16.

Further, the release paper 16 has a first cut 18 formed therein. The cut 18 is formed linearly at one end portion in the longitudinal direction of the release paper 16 from one end to the other end in the width direction of the release paper 16. A second cut 20 having, for example, a "U" shape is formed in the central portion of the release paper 16. In this case, the second cut 20 is connected to the points 18a and 18b which are slightly spaced inward from both ends of the first cut 18. That is, the cut 20 is formed so as to extend from the points 18a and 18b of the cut 18 to the other end of the release paper 16 in the longitudinal direction.

Therefore, the release paper 16 can peel off the portion 17a on the outer side of the first cut line 18, whereby the sticking adhesive layer 14 can be exposed. Also, this release paper 16
The outer part 17b of the second incision 20 can be peeled off, thereby exposing the sticking adhesive layer 14.

This encapsulating material 10 is, for example, as shown in FIG.
At 16, the outer portion 17b of the second cut 20 is peeled off so that the adhesive layer 14 can be applied, for example, to the surface of the delivery 29. In this case, the encapsulating material 10 forms a bag portion 24 in the release paper 16 between the substantially central portion 17c (the portion inside the second cut 20) and the surface of the delivery item 29. Further, the bag portion 24 has an opening 24a formed at an intermediate portion of the first cut line 18. Therefore, in the bag portion 24 of the encapsulating material 10, the storage object 28 such as a delivery note and a slip can be stored through the opening 24a. Further, by peeling off the portion 17a outside the first cut 18 of the release paper 16, the sticking adhesive layer 14 can be exposed. Thereby, one end of the base material 12 is attached to the adhesive layer 14
For example, stick it on the surface of the delivery 29 and open the opening of the bag 24.
24a can be sealed. Therefore, the stored item 28 does not undesirably come out of the bag portion 24. That is, since the stored item 28 stored in the bag portion 24 is covered by the base material 12 and the central portion 17c of the release paper 16, the stored item 28 can be prevented from being soiled and there is no risk of loss.

After attaching the encapsulant 10 to the surface of the delivery 29,
In order to take out from the bag portion 24, the central portion of the base material 12 may be cut at the perforations 22 and peeled off. In addition, this encapsulating material 10
As an example of the storage item 28 stored in the bag portion 24 formed by sticking, in addition to the delivery note and the slip,
Examples include warranty cards, labels, labels, etc., but any flexible sheet may be used.

Further, in this encapsulating material 10, since the base material 12 is formed of a thermosensitive color recording paper, for example, "in the delivery note", "in the warranty note" and "instruction manual in" are provided on the surface thereof. The display can be colored by a thermal printer.
Further, in this embodiment, the heat-sensitive color recording paper is used as the material of the base material 12, but the material may be synthetic resin materials such as polypropylene and polyethylene other than the heat-sensitive color developing paper.
