Abstract

A novel pressure-sensitive adhesive tape package easy to open and easy in application of an adhesive tape is disclosed. The pressure-sensitive adhesive tape package 10 according to the present invention includes an adhesive tape 14 that accommodates a support 18 and an adhesive agent layer 12 provided on one surface of the support 18 , and a release sheet 16 releasably attached to the adhesive agent layer 12 . Moreover, the release sheet 16 is folded with the adhesive tape 14 , and the adhesive tape 14 is sealed inside of the folded release sheet 16 . A plurality of temporary attach portions 50 to 54 spaced from each other is provided in a half of the adhesive agent layer 12 in the adhesive tape 14 to securely expose the half when the release sheet 16 is opened.

First claim

The invention claimed is:

1. A rectangular pressure-sensitive adhesive tape package accommodating an adhesive tape having a support, and an adhesive agent layer provided on one surface of the support, the pressure-sensitive adhesive tape package comprising a first portion and second portion formed of a release sheet releasably attached to the adhesive agent layer, the first portion and the second portion being layered, a periphery of the layered first portion and second portion being sealed, wherein
an entire first sealed portion along a first corresponding edge in the pressure-sensitive adhesive tape package, an entire second sealed portion extending along a second corresponding edge adjacent to the first edge and crossing the first sealed portion, and an entire third sealed portion extending along a third corresponding edge adjacent to the first edge and crossing the first sealed portion, are completely spaced from their corresponding edge;
the adhesive tape is accommodated in the pressure-sensitive adhesive tape package such that the adhesive agent layer faces outwardly in a state where the adhesive tape is folded into a first portion and a second portion;
the first portion of the adhesive tape is larger than the second portion of the adhesive tape, and has an extending portion extending from the second portion;
the extending portion is disposed adjacent to the first sealed portion, and temporarily attached with a plurality of temporary attach portions to a portion of the release sheet that is to be the second portion side of the adhesive tape; and
the plurality of the temporary attach portions is disposed along the first sealed portion, the second sealed portion, and the third sealed portion, and spaced from adjacent temporary attach portions.

2. The pressure-sensitive adhesive tape package according to claim 1 , wherein the first sealed portion, the second sealed portion, and the third sealed portion are heat-sealed portions.

3. The pressure-sensitive adhesive tape package according to claim 1 , wherein an interval between the first edge and the first sealed portion functions as a holding portion.

4. The pressure-sensitive adhesive tape package according to claim 1 , wherein a layer of the release sheet to be located inside of the pressure-sensitive adhesive tape package is formed of a thermoplastic material, and the temporary attach portions are provided by thermal bonding the layer formed of the thermoplastic material to the support of the adhesive tape.

5. The pressure-sensitive adhesive tape package according to claim 1 , wherein an adhesive force of the support of the adhesive tape to the release sheet through the temporary attach portions is larger than an adhesive force of the adhesive agent layer to the release sheet.

6. The pressure-sensitive adhesive tape package according to claim 1 , wherein means for suppressing an adhesive force that suppresses an adhesive force between the adhesive agent layer of the first portion of the adhesive tape and the release sheet is provided on at least a part of the release sheet.

7. The pressure-sensitive adhesive tape package according to claim 6 , wherein the means for suppressing an adhesive force is a silicone-treated surface provided on at least a part of a portion of the release sheet that is attached to the adhesive agent layer of the first portion of the adhesive tape.

8. The pressure-sensitive adhesive tape package according to claim 6 , wherein the means for suppressing an adhesive force is an embossed surface and/or sanded surface provided on at least a part of the portion of the release sheet that is attached to the adhesive agent layer of the first portion of the adhesive tape.

9. The pressure-sensitive adhesive tape package according to claim 1 , wherein the adhesive tape is used for a skin or a mucous membrane.

10. The pressure-sensitive adhesive tape package according to claim 1 , wherein the first portion and the second portion of the release sheet are formed by folding one release sheet.

11. The pressure-sensitive adhesive tape package according to claim 1 , wherein the first portion and the second portion of the release sheet are each formed of individual release sheets, and sealed along a fourth edge facing the first edge of the pressure-sensitive adhesive tape package.
