JP2000247061A - Anti-slip tack sheet for finger - Google Patents

Abstract

PROBLEM TO BE SOLVED: To allow repetitive use of an anti-slip tack sheet by cleaning the sheet with water or the like even if dust or the like is adhered to its surface by not covering the finger with the sheet but adhering the sheet to the finger. SOLUTION: In the tack sheet, an adhesive layer 3 adherable to a finger is laminated on one side surface of a sheet base material 1, a release sheet 5 is adhered to a surface of the layer 3, an urethane adhesive layer 7 is laminated on the other side surface of the material 1 and a release sheet 8 is adhered to the layer 7. In this case, adhesive force of the layer 7 is weakened as compared with the adhesive force of the layer 3 of the one side surface of the material 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finger non-slip tack sheet used as a substitute for a finger sack used for, for example, turning pages of a book or turning a slip.

[0002]

2. Description of the Related Art Conventionally, for example, when turning over pages of a book or turning over slips, a finger cot is attached to a fingertip.

[0003]

However, in the conventional finger cot, the finger may be stuffy due to sweat, and the fingertip may have a feeling of pressure, which may cause discomfort when used.

[0004] Therefore, there is also known a sheet-like tack formed in a predetermined shape, which is attached to a finger through an adhesive. Such a tackiness is extremely inconvenient and uneconomical, since dust and the like adhere to the surface of the book together with the operation of turning over the pages of the book, so that the frictional force is reduced and the frequent replacement is required.

The present invention has been made to solve such a problem, and can be attached to a finger instead of putting it on the finger.
Moreover, it is an object of the present invention to provide a finger slip resistant tack sheet that can be repeatedly used by washing with water or the like even when dust or the like adheres to the surface.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the feature of the finger non-slip tack according to the present invention is as follows. An adhesive layer 3 that can be adhered is laminated, a release sheet 5 is adhered to the surface of the adhesive layer 3, and a urethane-based adhesive layer 7 is laminated on the other side surface of the sheet substrate 1. The release sheet 8 is adhered to the pressure-sensitive adhesive layer 7, and the pressure-sensitive adhesive strength of the urethane-based pressure-sensitive adhesive layer 7 is lower than the pressure-sensitive adhesive strength of the pressure-sensitive adhesive layer 3 on one side of the sheet substrate 1.

When a tack consisting of the sheet substrate 1, the adhesive layer 3, and the urethane-based adhesive layer 7 is attached to the finger 12 to turn over a book page or the like, the sheet substrate has Since the urethane-based pressure-sensitive adhesive layer 7 is laminated,
Due to the adhesive force of the urethane-based pressure-sensitive adhesive layer 7, a frictional force is generated between the tack and the book or the like, so that the book or the like can be turned over reliably.

In addition, when the adhesion of the urethane-based adhesive layer 7 is reduced due to the attachment of dust or the like during the turning operation of the book or the like, the surface of the urethane-based adhesive layer 7 is washed with water and dried. The adhesion can be restored a considerable number of times.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a base film (tack main body) having a predetermined thickness, which has, for example, a circular shape in plan view. On one side of the tack body 1, normal butyl acrylate, 2-ethylhexyl acrylate, acrylic acid, 2-hydroxyethyl methacrylate,
An acrylic pressure-sensitive adhesive layer 3 mainly composed of vinyl acetate or the like is laminated on the entire surface, and a release sheet 5 is adhered to the surface of the pressure-sensitive adhesive layer 3.

On the other side of the tack body 1, a urethane-based pressure-sensitive adhesive layer 7 mainly composed of urethane resin is laminated on the entire surface, and a release sheet 8 is adhered to the urethane-based pressure-sensitive adhesive layer 7. I have. The pressure-sensitive adhesive strength of the urethane-based pressure-sensitive adhesive layer 7 is lower than the pressure-sensitive adhesive strength of the pressure-sensitive adhesive layer 3 on one side surface of the sheet substrate 1, and the urethane-based pressure-sensitive adhesive layer 7 is re-adhered by washing with water or the like. Can restore sex.

The tack body 1, the acrylic pressure-sensitive adhesive layer 3 and the urethane-based pressure-sensitive adhesive layer 7 form a tack 10.
Is configured. Then, a plurality of tacks 10 are adhered to the rectangular release sheet 8 to form a finger non-slip sheet body.

[0012] As a method of manufacturing such a finger anti-slip tape, an acrylic pressure-sensitive adhesive is applied to one side of a long base film 1 and a urethane-based pressure-sensitive adhesive layer 7 is applied to the other side. I do. Then, after sticking the long release sheets 5 and 8 on both sides of the base film 1, the release sheet 5 and the tack are removed by a half-cut device so that the release sheet 8 on the urethane-based pressure-sensitive adhesive layer 7 side is left. The main body 1 and the urethane-based pressure-sensitive adhesive layer 7 are cut in half. According to such a method,
There is an advantage that the manufacturing is simple and the cost is low.

The finger non-slip tape of the present embodiment has the above-described configuration. When the finger non-slip tape is used, the tack 10 is peeled from the release sheet 8 and the release paper 5 is removed from the tack main body 1. Peel off. And tack 1
The finger sticking surface 0 (the surface of the acrylic pressure-sensitive adhesive layer 3) is stuck to, for example, the thumb 12 (see FIG. 2B).

Since the surface of the urethane-based pressure-sensitive adhesive layer 7 of the tack 10 has an appropriate sticking force, when turning a page or the like of a book,
The anti-slip effect can be secured, and the turning operation can be performed reliably. Urethane adhesive layer 7 of tack with turning work
Adhesion is weakened by the attachment of dust and the like to the surface. When the adhesive strength is weakened, the tack-slip inhibiting effect is reduced.

Therefore, the surface of the tack is washed with tap water or the like with the tack attached to the finger to remove dust and the like adhering thereto. The tackiness of the tack surface is restored by washing and drying, so that the tackiness can be recovered a considerable number of times. Therefore, the work of turning a book or the like can be performed with the tacky tackiness that has been recovered.

The present invention is not limited to the above-described embodiment, and the pressure-sensitive adhesive applied to the finger has such an adhesive strength that it does not accidentally peel off during the turning operation. If so, it may be other than the above-mentioned acrylic adhesive.

The shape of the tack may be any shape other than a circle, such as an ellipse or a polygon.

[0018]

As described above, the finger non-slip tack sheet according to the present invention has a pressure-sensitive adhesive layer that can be attached to a finger on one side of a sheet substrate, and a release sheet on the surface of the pressure-sensitive adhesive layer. Is adhered, and, on the other side of the sheet substrate, a urethane-based pressure-sensitive adhesive layer is laminated, a release sheet is adhered to the urethane-based pressure-sensitive adhesive layer, and the adhesive force of the urethane-based pressure-sensitive adhesive layer is a sheet. Since the adhesive strength of the adhesive layer on one side of the base material is weaker, the adhesive can be washed with water or the like and used repeatedly, which is very convenient and economical.
