Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to characters and figures made of ink which cannot be erased with an eraser, such as handwriting of a ball-point pen and a marking pen, and printing marks of an ink-jet printer and a dot impact printer. The present invention relates to a correction tool containing a correction liquid that can be rewritten after being hidden and dried, and particularly to a correction tool using a correction liquid in which titanium oxide is dispersed in a hydrocarbon solvent.

[0002]

2. Description of the Related Art Heretofore, correction fluids have been prepared by dissolving a white pigment such as titanium oxide zinc oxide, a hydrocarbon-based organic solvent such as methylcyclohexane, cyclohexane or isooctane which does not dissolve oily or aqueous handwriting, and a water-soluble organic solvent. It contains at least a fixing agent such as an acrylic resin or an alkyd resin. As a white pigment, titanium oxide having particularly high concealing properties is often used.

[0003] As a correction tool, the above-mentioned correction liquid is adjusted to a viscosity of several tens to several hundreds mPa · s, and is used by filling it into a container provided with a brush or a container provided with a valve type applicator.

[0004]

At present, most correction fluids using commercially available hydrocarbon solvents are filled in containers such as nylon. The correction liquid easily adheres to this container, and it is difficult to use all of the filled correction liquid. Further, even if the container is transparent or translucent due to the adhesion, there is a problem that the remaining amount of the correction liquid cannot be confirmed. Therefore, the present invention minimizes the possibility that the correction liquid adheres to the container, and can use all of the filled amount.Furthermore, when a transparent or translucent container is used, a correction tool that can check the remaining amount is used. The purpose is to provide.

[0005]

That is, the present invention has an application section for applying a correction liquid as a content liquid at the tip, and a concealing agent is provided on a side of the application section in a tank containing the correction liquid. A correction liquid comprising at least a hydrocarbon solvent having a boiling point of 40 to 150 ° C. and a film-forming agent soluble in the solvent is accommodated, and comes into contact with a rear interface of the correction liquid to form a hydrocarbon-based solvent of the correction liquid. The gist of the present invention resides in a correction tool containing at least a backflow preventive body composed of an insoluble or hardly soluble organic solvent and / or water, a viscosity modifier and a surfactant.

The details will be described below. The application portion of the correction liquid is of a conventionally used type such as a tip valve type or a brush type, and can be used without any problem as long as the condition that the discharge amount of the correction liquid to be used can be ensured. For example, in the tip valve type, the coating portion supports a ball or a cylindrical valve body with a spring, and forms a valve by closely contacting the valve with the inner edge of the tip pipe portion.
The structure is such that evaporation of the solvent of the correction fluid is suppressed. As the material of the valve body, a resin such as polyacetal or polybutylene terephthalate, or a metal such as stainless steel or brass can be used.

[0007] The correction liquid tank to which the above-mentioned coated body is attached is
A transparent or translucent material capable of confirming the remaining amount of ink is preferable. Examples of the material include nylon, polyethylene terephthalate, polypropylene, polyethylene, and Teflon (registered trademark). Nylon and polyethylene terephthalate are preferable in consideration of solvent resistance. Further, in order to further suppress the adhesion of the correction liquid to the correction liquid tank, the inner wall surface of the housing pipe has an arithmetic average roughness (Ra) of 500.
nm or less, and the maximum height difference (PV) is preferably 5000 nm or less in surface roughness (JIS B0601). Further, the shape of the correction fluid tank is preferably a cylindrical body having a circular cross section like a general synthetic resin extruded pipe, but the inner diameter may be different depending on the portion, or the cross section may be a square or the like. It may be an injection molded product having a square shape or any other shape.

[0008] The correction liquid is a liquid for concealing and correcting handwritings and designs, and comprises at least a concealing agent such as titanium oxide, a hydrocarbon-based solvent having a boiling point of 40 to 150 ° C, and a film-forming agent soluble in the solvent. It is.

In order to ensure the anti-reflux function of the anti-reflux agent, and to enhance the anti-drying function and anti-reflux function of the anti-drying body made of the liquid composition, the anti-reflux agent may be located inside the anti-reflux body. Floats can also be placed. The float may be arranged on each of the backflow preventive body and the drying preventive body made of the liquid composition, or on only one of them. Alternatively, a common float may be arranged on both sides. When a solid anti-drying member is used, the function of a float can be provided by arranging the tip portion inside the anti-reflux member. Examples of the shape of the float include a column shape, a ball shape, a board shape, a polygonal column shape, and a cup shape.

[0020]

It is not clear why the correction liquid according to the present invention does not adhere to the correction liquid tank, but the solvent used for the correction liquid and the solvent used for the backflow preventer do not mix with each other. The liquid is repelled at the interface of the backflow preventer. In addition, the backflow preventive gelled by the viscosity modifier has a higher viscosity when it is allowed to stand still due to its gel structure, and furthermore, the surface tension of the backflow preventer decreases due to the addition of a surfactant, so that the backflow can be prevented. The wettability between the preventing body and the correction liquid tank is improved, and the correction liquid attached to the correction liquid tank is easily scraped off. It is presumed that for these reasons, the correction fluid is less likely to adhere to the correction fluid tank.
