Abstract

(57) [Summary] [Purpose] While being lightweight and convenient to handle, it should be able to be firmly fixed on the table during use. [Structure] The cutter body 1 is configured as a hollow shell structure in which a weight-imparting body is not loaded, and fixing adhesive pieces 5 and 5 are attached to a plurality of lower surfaces in a protruding manner on the lower surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention mainly relates to a desk-top type adhesive tape cutter used for office work.

[0002]

[Prior art]

 The table-top adhesive tape cutter is required not to move freely on the table in order to facilitate the operation of pulling out and cutting the adhesive tape with one hand. Due to such a requirement, the conventional tape cutter can prevent sloppy movement on the table by loading mortar or other weight-bearing body in the cutter body and constructing it with a considerable weight. It was normal to assume.

[0003]

[Problems to be solved by the device]

 However, the above conventional products have problems that they are not only disadvantageous in transportation due to their large weight but also high in cost and inconvenient to carry.

Therefore, the present invention aims to provide a simple adhesive tape cutter that can be manufactured at a low cost as an extremely lightweight product, and does not easily move on the table during use and has no practical problems. To aim.

[0005]

[Means for Solving the Problems]

 For the above-mentioned purpose, the present invention provides a cutter body that rotatably supports an adhesive tape wheel via a reel and has a cutting blade at one end for cutting the adhesive tape pulled out from the adhesive tape wheel. A shell body made of a synthetic resin molded product whose lower surface is open and a bottom plate closing the bottom surface of the shell body to form a hollow shell structure in which a weight-bearing body is not loaded. A gist of an adhesive tape cutter is characterized in that pressure-sensitive adhesive pieces made of a pressure-sensitive adhesive are provided in a downward projecting manner at least at two or more positions separated from each other on a lower surface of a bottom plate.

The pressure-sensitive adhesive piece uses a pressure-sensitive adhesive that repeatedly exhibits adhesive force, and has a preferable constitution with a pressure-sensitive adhesive tape made of one of rubber-based, acrylic-based, and silicone-based pressure-sensitive adhesives. Use as material.

[0007]

[Action]

 Since the cutter body is composed of a hollow shell structure, it is extremely lightweight as a whole. For example, as a tape cutter used for an adhesive tape wheel with an inner diameter of 76 mm, make a lightweight product of about 100 to 150 g. Can

On the other hand, since the bottom surface of the bottom plate is provided with a plurality of adhesive pieces at a plurality of places, the cutter body is stably held by the adhesive force of the adhesive pieces when placed on a table, and the tape is removed from the adhesive tape loop. It does not move unintentionally when pulling out or cutting the adhesive tape. Of course, since the above-mentioned adhesive piece is made of a pressure-sensitive adhesive, it repeatedly exerts its adhesive force and can be separated from the table and moved to be reused repeatedly at other places without any trouble.

【Example】

 In FIG. 1, (1) is a cutter body, (2) is a reel that is rotatably and detachably supported by the cutter body, and (3) is one end of the cutter body (1) at a position corresponding to the reel. The cutting blade is provided upward in the drawing, (4) is an adhesive tape ring mounted on the reel (2), and (4a) is an adhesive tape pulled out from the reel.

Although the above-mentioned structure is basically substantially the same as the conventional product, the adhesive tape cutter according to the present invention has a hollow and lightweight structure in which the cutter body (1) is not loaded with a weight-imparting body therein. It is characterized in that it is constructed as a shell structure and that a plurality of adhesive pieces (5) are provided on the lower surface thereof.

The cutter body (1) has a space (6) inside and a shell body (1a) made of a hard synthetic resin molded product having an open lower surface, and a hard synthetic resin body having the lower surface closed. It is composed of a bottom plate (1b) and is configured as a shell structure having a completely hollow inside. The bottom plate (1b) is forcibly fitted into the lower surface opening of the shell body (1a), and is joined to the shell body (1a) by the engaging portions (8) at a plurality of peripheral positions, and is integrated therewith. .

The bottom plate (1b) is provided with a recess (9) having a rectangular depth of about 0.1 to 0.3 mm at two locations near both ends in the length direction thereof. The adhesive piece (5) having a corresponding shape is provided so as to be fitted and to be slightly projected downward.

The pressure-sensitive adhesive piece (5) is made of a pressure-sensitive adhesive, and preferably a pressure-sensitive adhesive tape piece formed by applying the adhesive to both surfaces of a base material such as paper or non-woven fabric to form a tape shape. It The type of adhesive is not particularly limited. For example, a rubber-based, acrylic-based or silicone-based pressure-sensitive adhesive can be appropriately selected and used. However, in any case, it is necessary to select and use one having a so-called adhesive life, which has a strong adhesive force as much as possible, but which can be peeled and re-adhered while retaining the adhesive force.

[0014]

[Effect of device]

 As described above, the present invention is extremely lightweight as a whole because the cutter body is hollow inside and is configured as a shell structure that does not load heavy objects, which is advantageous for transportation and carrying, and transportation costs. It is possible to reduce the cost of products, which occupy a large percentage, and to provide them at low cost.

Since the adhesive pieces are provided on the lower surface of the cutter body at a plurality of locations, the cutter body can be firmly attached to the table with the adhesive force of the adhesive piece when it is placed on a table and used. Can be fixed. Therefore, when the adhesive tape is pulled out or cut, the cutter body does not inadvertently move and can be conveniently used with one hand.
