Abstract

PROBLEM TO BE SOLVED: To provide a coating film transfer tape adapted so that its pressure- sensitive adhesive layer can be exactly cut without using any cutter and can be transferred. SOLUTION: A pressure-sensitive adhesive tape 12 is composed of a pressure- sensitive adhesive layer 3 and a base tape 5. A plurality of parallel protruding streaks 8 rectangular to the winding direction on the upper surface of the tape 5, and thin-coated parts 11 coinciding with the streaks 8 are formed on the surface on the side of the tape 5 of the layer 3 applied thereto. When in use, the adhesive is pressed against the surface of e.g. paper, whereupon the adhesive can be cut easily and exactly at the thin-coated part of any desired position and the area of contact between the base tape containing the related protruding streak and the pressure-sensitive adhesive increases to heighten the force of holding both. The protruding streaks on the bottom of the pressure-sensitive tape prevents the tape from blocking to the pressure-sensitive adhesive tape laid thereon.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator tape for applying an adhesive glue or transferring a correction coating film.

[0002]

2. Description of the Related Art Conventionally, this type of applicator is provided with an adhesive glue layer on one surface of a base tape (base material) wound in a tape shape, and discharging the tape from one end, for example, through a roller. Or, it is folded back with a tongue-shaped head, pressed against the paper, etc. to form a glue layer (coating) on the paper, and then glued to each other and other things with this glue layer, and a sticky note on the paper And so on. Then, in order to provide an adhesive layer on the base tape, a transfer film (adhesive layer) is formed on the base tape (base material) by forming an irregular uneven surface finely (Japanese Utility Model Publication No. 8-4320). Alternatively, a device has been proposed in which a groove is provided in the space between the pressure-sensitive adhesive layer and the surface of the adherend so as not to generate air bubbles (Japanese Utility Model Application No. 3-67043).

[0003]

However, the above-mentioned conventional one uses a tape having a particularly strong adhesive force.
When a glue layer is formed on the paper surface and the edge is cut at a predetermined position, the glue is poorly cut, resulting in a so-called stringing state.The glue cannot be cut at the predetermined position, and the surrounding glue is pulled. The cutting may take a considerable amount of skill. In addition, as described in the above-mentioned publication, an irregular uneven surface is formed to provide an adhesive layer on the base tape, thereby improving the adhesion between the two, or forming a groove up to the edge to generate bubbles. However, in any case, if it is attempted to cut the tape at a predetermined position, it is difficult to cut the tape at that position.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and makes it easy to separate an adhesive layer from a base tape and to prevent the adhesive layer from being formed in a dump at a predetermined position. It is designed to be cut substantially perpendicular to the winding direction.

[0005]

For this purpose, the present invention relates to a glue tape (adhesive tape) or a correction coating film transfer tape comprising a base tape and an adhesive layer formed thereon, wherein the adhesive layer Is formed by forming a thin portion from the one side edge to the other side edge on the back surface of the adhesive layer by a ridge provided at an interval substantially perpendicular to the winding direction of the tape to be wound. In addition, a release layer is formed on both sides of the base tape to separate the base tape and the adhesive layer.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the present invention has the above-mentioned structure, a film tape such as polyethylene terephthalate resin (PET) or glassine paper is used as a base tape, and a release film is appropriately formed on the surface of the tape. Is to apply a sticky material via At this time, ridges are formed on the base tape at regular intervals substantially perpendicular to the longitudinal direction (winding direction), and an adhesive film is applied thereon. At this time, in the manufacture, the dimensional control of the application thickness of the adhesive film is performed using the thickness including the base tape, and a thin wall from one edge parallel to the back surface of the adhesive layer (the base tape side) to the other edge is used. Unit is configured. When this tape is pressed and adhered to the surface to be adhered, for example, by a roller or a tongue-shaped head portion, only the adhesive layer is transferred onto the paper surface, and the base tape is wound around a take-up portion (take-up reel). Will be taken. Note that a correction coating film can be used as the adhesive film.

When a predetermined portion of the adhesive layer (glue portion) is adhered to the paper surface (adhered surface) and cut at a predetermined position, the adhesive layer is easily cut at a thin portion near the predetermined position. And the back surface is stuck on the paper surface in a form cut at a right angle to the winding direction without using the adhesive layer and forming the adhesive layer into a dumpling shape. A predetermined tag, for example, can be easily attached to this surface portion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
(1) is a glue container, and a glue tape (hereinafter, referred to as “adhesive tape”) composed of a base tape (5) on which an adhesive layer (3) is applied. ] (12). A part of the container (1) is provided with an opening (9) from which a roller (2) and a holding part (10) for holding the roller (2) can protrude. The adhesive tape is provided between the supply reel (4) and the take-up reel (6), which are mounted on the roller (2) of the holding section (10) projecting from the opening section (9) and which is mounted on the glue container (1). (1
2) is passed over (FIG. 3). The base tape (5) of the adhesive tape (12) is provided in advance with ridges (8) that are substantially perpendicular to the winding direction with appropriate intervals. In the case of a slender base tape, the ridges (8) are provided substantially at right angles to the winding direction (the longitudinal direction when winding on a supply reel),
An adhesive layer (3) made of an adhesive or the like is applied on the base tape (5) via a thin layer (release film) of silicone (FIG. 4). The supply reel (4) and the take-up reel (6) are provided with gears (not shown) coaxially with each other as in a conventionally known structure, and the supply reel (4) is rotated by meshing the gears. Is transferred to the take-up reel (6), and the take-up reel (6) rotates with the supply of the adhesive tape (12), and the adhesive tape (12) from which the adhesive layer (3) has been peeled off.
Is wound on a winding tape (6).

Since the first embodiment has the above-described structure, the adhesive tape (12) which is wound on the take-up reel (6) from the supply reel (4) in the glue container (1) and abuts on the roller (2). ) Is guided so that the adhesive layer (3) comes into contact with the paper surface (the surface to be adhered), protrudes from the opening (9) of the glue container (1), and transfers the adhesive layer (3) to the paper surface. As described above, only the base tape (5) is wound on the take-up reel (6). When the adhesive layer (3) is pressed at a predetermined position on the paper surface, the adhesive layer (3) is
Is cut at the thin portion (11) of the adhesive layer (3) formed by the ridge (8). Then, since the cut surface is the thin portion (11), it can be neatly adhered almost perpendicularly in the length direction without being rounded or formed into a messy line. In addition, since the contact area between the adhesive layer (3) and the base tape (5) increases at the protruding ridge (8), the holding force of both increases, and when the coil is wound. Blocking is less likely to occur.

FIG. 5 shows a second embodiment, which differs from the first embodiment only in the method of forming the ridges (8) on the base tape (5 '). It has a configuration to perform. That is, the formation of the protrusions (8) on the base tape (5 ') is performed by pressing a roller (not shown) for providing the protrusions on the front surface from the back surface (the side without the adhesive layer) of the base tape (5'). It is formed by this. When forming the ridge (8) by this method,
When the base tape (5 ') is wound up, the adhesive portion of the adhesive layer (3), which comes into contact with the lower surface, does not adhere to the entire surface, so that the tapes can be more easily peeled off than in the first embodiment. The tape can be easily fed.

In a third embodiment shown in FIG. 6, a ridge (8) is formed on a base tape (5), and a release film (7) made of silicone or the like is formed on both surfaces thereof. With this configuration, when the adhesive tape (12) including the adhesive layer (3) and the base tape (5) is concentrically wound and overlapped, the peeling of the overlapped tapes becomes easy. Things.

In a fourth embodiment shown in FIG. 7, parallel uneven portions are formed on the front and back of the base tape (5) at appropriate intervals, and the protrusions are formed at one longitudinal edge of the base tape (5). By providing it to the other end edge, cutting can be easily performed. In addition, when wound and superimposed, the tapes are bonded to each other, that is, so-called blocking can be prevented.

[0013]

As described above, the present invention is provided with a cut portion such as a dispenser because a thin portion is formed at right angles to the winding direction of the tape on the adhesive layer coated on the base tape. It can be cut at any time without any trouble.
The cut part is not rounded and the broken part does not have irregular parts that are disturbed.Furthermore, the blocking phenomenon between the adhesive tapes when winding and overlapping can be held in the correct position with the contact part as a ridge part In addition, the ridge portion of the base tape and the adhesive layer in contact with the ridge portion have an effect of increasing the contact area or surface, thereby increasing the holding force of the two.
