Abstract

PROBLEM TO BE SOLVED: To provide a small-sized and cutter easy to use for a pressure sensitive adhesive tape. SOLUTION: A pressure sensitive adhesive tape passing hole is provided on this side of the cutter of a simplified cutter mechanism moving along the outer periphery with a pressure sensitive adhesive tape roll held, whereby the tape is always kept in a drawn state to this side of the cutter by utilizing the frictional force of the pressure sensitive adhesive surface. This arrangement can overcome the disadvantage that the end of the pressure sensitive adhesive tape slips off the cutter mechanism and sticks to the tape roll main body. A margin to stick the tape is provided on the tape pressure sensitive adhesive surface side of the passing hole, and the pressure sensitive adhesive area can be reduced by applying a separating material or angle-cutting, so that while strong sticking is prevented, the tape can be stored without exposing the pressure sensitive adhesive surface to simply draw out the tape end in the next use.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention eliminates the problem that the end of an adhesive tape sticks to a tape winding body by providing a tape passage hole in front of a blade in a cutter mechanism which moves around the outer circumference while holding an adhesive tape winding. The present invention relates to a simple cutter in which a tape attaching margin is provided on the tape adhesive surface side of the passage hole so that the adhesive surface can be stored without exposing the adhesive surface.

[0002]

2. Description of the Related Art A simple cutter for an adhesive tape which moves around the outer periphery while gripping the adhesive tape winding is widely used because it is inexpensive and small.

In addition, a mechanism has been devised in which a pressure-sensitive adhesive tape roll is set on a roller and the pressure-sensitive adhesive tape is cut with a fixed blade, thereby improving usability.

[0004]

Since the simple tape cutter does not have a function of holding the end of the adhesive tape by the cutter mechanism, the end of the adhesive tape is easily detached from the cutter mechanism, and furthermore, the end of the adhesive tape is a tape winding main body. In many cases, it was necessary to perform a troublesome work of pulling out the tape end in the next use.

On the other hand, a mechanism for setting an adhesive tape on a roller requires not only a large amount of mechanical material but also an expensive one. It is rather difficult to use when carrying the tape to the place where it is attached.

[0006] The method of setting the adhesive tape on the roller is such that if the tape is frequently used, such as cellophane tape, the cutter can be sold separately and only the tape can be replaced. It is irrational to sell only expensive cutters separately in this type.

[0007]

As a result of intensive studies to solve the above-mentioned problems, the present invention reduces the frictional force of the tape adhesive surface by providing a tape passage hole in front of the blade of a conventional simple cutter. Utilizing the adhesive tape, the adhesive tape can always be pulled out in front of the blade.

Further, a tape attaching margin is provided on the tape adhesive surface side of the passage hole to apply a release material and reduce the adhesive area, so that strong adhesion can be prevented and the adhesive surface can be stored without exposing the adhesive surface. .

BEST MODE FOR CARRYING OUT THE INVENTION The structure and method of use of the present invention will be specifically described below, but the scope of the present invention is not limited to the examples described below. The cutter mechanism provided by the present invention comprises a blade (4), a tape passage hole (2), a tape sliding mechanism (5), a tape winding gripping part (6), and a tape sticking margin (7).

Although any material and structure can be used for the cutting tool (4) used in the present invention, it is necessary that the cutting tool (4) be safe and capable of easily cutting the adhesive tape.

Although the shape of the tape passage hole (2) is not particularly specified, a long side is wider than the width of the tape, and a short side is a rectangle larger than the tape thickness. In this case, it is easier to use the short side length to a certain extent in order to pull out the tape, but if it is too large, friction with the tape adhesive part is less likely to occur, so it is necessary to clarify the optimum value for the tape material by experiments, etc. is there.

When the present cutter mechanism is manufactured by sheet metal processing of a single sheet, a U-shaped cut is made in the sheet metal.
By folding back, the tape passage hole (2) and the tape sliding mechanism (5) can be formed simultaneously.

The tape sliding mechanism (5) prevents the tape from being damaged on the side surface of the tape passage hole, and at the same time, applies a force for the entire cutter mechanism to move on the outer periphery of the tape by the pressure generated by the tension of the tape. give. Specifically, the tape sliding mechanism is realized by a smooth surface or a roller having low friction.

The tape gripper (6) is a mechanism for the cutter mechanism to grip the tape winding and to move smoothly along the tape outer periphery. This mechanism can be realized by bending a thin metal plate and pressing the inner surface of the tape winding. Further, a roller that enters the inside of the tape may be used. These mechanisms are known to those skilled in the art and can be appropriately selected.

The tape attaching margin (7) is to prevent the adhesion of dust and the like due to the exposure of the adhesive surface by attaching the tape adhesive surface to this portion when the adhesive tape is stored, and to prevent the cutter from being attached to the end of the adhesive tape. It is intended to prevent detachment from the mechanism.

[0016] The tape attachment margin needs an area such that the cutter mechanism does not become unnecessarily large. minimum,
It is necessary to have a circumferential length greater than the distance between the blade (4) and the tape passage hole (2) and a width greater than the width of the tape.

By applying a release material to the upper surface of the tape and applying an upwardly convex shape, corrugating or meshing to the upper surface of the tape to reduce the contact area between the tape adhesive surface and the tape bonding surface, the tape end can be made strong. Prevent sticking and allow easy removal of the tape end so that it can be used for the next use.

Such a process for reducing the sticking strength is performed at a place distant from the tape passage hole (2) to a certain extent, so that an adhesive tape is stuck near the tape passage hole to provide a holding strength, and The end can be easily peeled off.

Further, the tape attaching margin (7) is formed by making the whole a convexly curved surface or a bent plane,
The end of the adhered adhesive tape becomes easier to peel off.

[0020]

According to the present invention, the disadvantage that the tape end of the simple tape cutter detaches and sticks to the tape winding body is eliminated. For this reason, a simple tape cutter having features of small size, light weight, and resource saving can be used as all kinds of adhesive tape cutters, and the cost and the resource saving of the adhesive tape including the cutter can be realized.
