消耗性固形材を提供するにある。[Detailed description of the invention] This invention is a consumable material in which the outer periphery of a so-called consumable solid material such as a solid erasing material such as an eraser or a solid drawing material such as a crayon, a pass, a pencil, or a conte is wrapped with a synthetic resin film. This relates to solid materials, and its purpose is to use a synthetic resin film wrapped around the outer circumference of the consumable solid material to expose the tip of the consumable solid material when it becomes short due to use, making it easier to use. A consumable solid material that makes it possible to tear the plastic film sequentially, improves the tearability of the initial synthetic resin film, improves the strength of the consumable solid material, and prevents the consumable solid material from staining hands and fingers. is to provide.

すことが出来なくなるといつた欠点があつた。 Conventionally, a solid drawing material is wrapped around a synthetic resin film that has an adhesive layer and a tab, and the film is torn from the tab by taking advantage of the weak adhesive force between the solid drawing material and the synthetic resin film. The invention (1976-157684) was known. However, in this case, there is a drawback that when the material is torn from the grip, the nail comes into contact with the solid drawing material, which stains the nail.Also, when used as an eraser, the adhesive force between the eraser and the synthetic resin film is strong and the grip is damaged. The drawback was that it could not be easily removed from the surface.

る。 Therefore, the inventors of the present invention have conducted various studies to solve the above-mentioned drawbacks, and as a result, they have developed a synthetic resin film as a method to improve the initial tearability regardless of the strength of the adhesive strength between the consumable solid material and the synthetic resin film. Weakens the adhesive strength of the polymerized part of the film and synthetic resin film,
They discovered that the polymer can be torn at the overlapping part and completed the present invention. That is, the present invention has a synthetic resin film body in which cuts are formed at arbitrary intervals on one side edge, an adhesive layer is formed on one side of the synthetic resin film, and a release layer is formed on the other side where it overlaps with the one side edge. The gist of the present invention is a consumable solid material which is wound so that the adhesive layer is in contact with the outer periphery of the solid material body, and whose ends are polymerized with one side on which the cut is formed facing upward.

以下、図面に基づき本考案を詳細に説明する。 Hereinafter, the present invention will be explained in detail based on the drawings.

かれる。 1 to 4 show an embodiment of the present invention, in which an adhesive layer 2 is formed on one side of a synthetic resin film 1 with cuts 1a formed at arbitrary intervals on one side edge, and an adhesive layer 2 is formed on one side of the synthetic resin film 1 on the other side. A synthetic resin film body 4 with a release layer 3 formed on the portion that overlaps with the end is wound around the outer periphery of a main body 5 of a consumable solid material such as an eraser or a solid drawing material so that the adhesive layer 2 is in contact with the slit 1a. This is a consumable solid material 6 whose ends are polymerized with one formed side facing up. When the tip of the consumable solid material main body 5 of the consumable solid material 6 becomes short, the
As shown in the figure, the peeling layer 3 and the synthetic resin film 1 are separated by pulling the end of the overlapping part along the cut 1a.
Because the adhesive force between the release layer 3 and the adhesive layer 2 is weak, the release layer 3 transfers from the surface of the synthetic resin film 1 to the surface of the adhesive layer 2, so it is easily torn, and then at the cut 1a. It is torn in a circular pattern along the line.

の要旨を逸脱するものではない。 Note that the shape of the consumable solid material main body 5 is not limited to the prismatic shape as in the embodiment, but various shapes such as a cylinder and a polygonal column can be used. The release layer 3 is formed by coating or printing a release material, but if necessary, it may be a layer that has stronger adhesive force to the adhesive layer 2 than to the synthetic resin film 1.
Further, it is preferable that the release layer 3 is formed on at least all or a part of the part where the synthetic resin film body 4 is polymerized, but there is no problem with the present invention even if it is formed over the entire surface of the synthetic resin film 1 or in an area other than the part where it is polymerized. This does not deviate from the gist.

以上に示した如く、本考案の消耗性固形材は初

など多くの利点を有するものである。 As shown above, the consumable solid material of the present invention not only has the advantage of having excellent initial tearability and being able to prevent stains on hands and fingers as much as possible, but also uses an adhesive layer with relatively strong adhesive strength. Therefore, it has many advantages such as improving the strength of the consumable solid material and improving workability during winding.
