JPH08132789A - Functional eraser - Google Patents

Abstract

PURPOSE: To provide a low-cost functional eraser which can maintain aromatic or anti-bacterial function for a long period. CONSTITUTION: A character eraser comprises erasing material containing single or composite material of rubbers such as natural rubber, synthetic rubber, emulsion rubber or plastics such as vinyl chloride, polypropylene, filler, lubricant, plasticizer, colorant or the other matter in mixture, and granular aromatic or anti-bacterial agent mixed in erasing material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional eraser having an eraser material having an aromatic or antibacterial effect.

[0002]

2. Description of the Related Art There are some commercially available erasers having an aroma or antibacterial function. However, since the surface of the eraser is exposed to the air, the aroma or antibacterial function may be impaired for a long period of time. there were.

Further, an eraser containing an fragrance or an antibacterial agent has a fragrance function which is impaired in the melt-mixed state of about 100 ° to 160 ° C. at the time of manufacture, so that it is manufactured with a large amount of vaporized eyes. It was an eraser that smelled too much.

The composition of these erasers is composed entirely of erasers having an aroma or antibacterial function, so as not to impair the aroma or antibacterial function for a long period of time by being exposed to the air from the surface of the eraser. The eraser is wrapped with cellophane film, wrap film, or the like.

Further, there is a microcapsule in which an eraser is used as an eraser in which an aromatic substance is confined, and there is a substance in which the smell of the aromatic substance is hard to be transferred even if the eraser is directly touched with a hand.

[0006]

However, if the wrapping material such as cellophane film or wrap film is removed, the fragrance or antibacterial function is suddenly impaired. There wasn't.

Further, the eraser containing the fragrance or the antibacterial agent has a lot of eyes because the aroma function is impaired in the melt-mixed state of about 100 ° to 160 ° C at the time of production, and therefore the smell is strong. Too much and may adhere to other materials.

Further, although there is an eraser made of an eraser material in which a fragrance is contained in a microcapsule, it takes a lot of time and labor to form the eraser material, and the cost becomes high.

The present invention has been made in view of the above circumstances, and an object thereof is to provide at low cost a functional eraser capable of maintaining a fragrance or antibacterial function for a long period of time.

[0010]

[Means for Solving the Problems] The feature is that rubber such as natural rubber, synthetic rubber, emulsion rubber or the like or plastic such as vinyl chloride or polypropylene is used alone or a composite material thereof, and a filler or a lubricant. In an eraser made by blending a plasticizer, a coloring agent, etc.,
A functional eraser characterized by being formed by mixing a granular fragrance or antibacterial agent into the eraser.

[0011]

With the above construction, when using this functional eraser, it is sufficient to rub the paper surface like a normal eraser.

In particular, the functional eraser of the present invention can be used for a long period of time without rapid vaporization because a granular fragrance or antibacterial effect can be obtained by frictional heat just by rubbing the paper surface.

Further, since the scent of the fragrance does not come out from the part that is touched with the hand, the eraser can be touched with confidence.

[0014]

[Examples] This feature is characterized by rubbers such as natural rubber, synthetic rubber, emulsion rubber or vinyl chloride,
An eraser made by blending a filler, a lubricant, a plasticizer, a coloring agent, and the like with a simple substance of plastics such as polypropylene or a composite material thereof, and a granular aromatic or antibacterial agent in the eraser. It is a functional eraser characterized by being mixed, and in other words, its greatest feature is that the granular fragrance or antibacterial agent is covered with the eraser.

When producing this, natural rubber,
Synthetic rubber, emulsion rubber and other rubbers, vinyl chloride, polypropylene and other plastics alone or in combination with these materials, fillers, lubricants, plasticizers, colorants, etc., and input from the hopper of an extrusion molding machine. Then, a fragrance agent or an antibacterial agent in the form of granules is charged into the melt-mixed state at about 100 ° to 160 ° C, and the eraser material softened by the screw in the heating cylinder of the extrusion molding machine is extruded into a die. A functional eraser is produced by continuously extruding from a (die) and passing it through cooling water on the discharge port side into a desired shape (called forming), and then cutting it into a predetermined shape.

[0016]

Since the present invention is constructed as described above, it exerts a great effect as described below.

Since the granular fragrance or antibacterial agent is covered with the eraser, it is not necessary to see a large amount of vaporization, the amount is small, the cost is low, and the strong odor causes discomfort. It does not adhere to other materials.

Compared to an eraser consisting of an eraser in which a fragrance is contained in a microcapsule, the process of making the eraser requires less time and effort, and can be handled in the same way as an ordinary eraser, thus reducing costs. Also cheaper.

Since a granular fragrance or antibacterial effect can be obtained by frictional heat only by rubbing the paper surface, it can be used for a long period of time without vaporizing quickly.

Further, since the scent of the fragrance does not come out from the part that is touched by the hand, the eraser can be touched with confidence.
