Description

The present invention relates to a black ink container in which the content of the black liquid can be easily confirmed and can be appropriately taken out without the black liquid adhering to the inner wall of the container.

Conventionally, when molding a plastic of a black ink container, a high-density polyethylene and a colorant for plastic (master badge) are used as a base material of the container to form a black ink container. Regarding other liquid storage containers for calligraphy, for example, the red liquid for correction is a translucent container that is red or uncolored.

Liquid ink for calligraphy (hereinafter referred to as ink) currently on the market is made by kneading carbon black with an aqueous solution of glue or a water-soluble synthetic resin, and adding surfactants, preservatives, and fragrances as needed. It is added and dispersed with carbon black using a disperser, and prepared with water so as to have a constant viscosity and concentration. Adjustments are made according to the characteristics of the product, from ordinary ink to ultra-dense ink. The viscosity of the black ink is 5.0 mPa · s (20 ° C) for normal black liquid and 80.0 mPa · s (20 ° C) for ultra-dense black ink. The surface tension of the ink liquid is preferably 40 to 50 mN / m (20 ° C.).

Since the ink container colored with the colorant for plastic is not transparent, the content cannot be visually determined. Even if the ink is stored in an uncolored transparent or translucent container, the ink adheres to the inner wall of the immersed container by storing it for a long period of time.

Conventionally, as shown in Patent Document 1, the graduated storage container itself is already known. However, there is no storage container having a structure suitable for the ink liquid storage container. In Patent Document 1, the container is a PET bottle, and the container base material is polyethylene terephthalate. The surface tension value of polyethylene terephthalate is 41 to 43 mN / m, which is higher than the surface tension value of polyethylene 32 to 36 mN / m, so that ink is attached at an early stage. In addition, there is no mechanism to prevent the contents from remaining on the inner wall of the container, which makes it unsuitable for use as a black ink container.

In general, a liquid having a lower surface tension and a higher viscosity causes dripping because it has a higher wettability with respect to the container substrate. Therefore, even if the storage container is tilted to move the ink liquid from the attachment point, the ink liquid having the above characteristics remains on the inner wall of the container and hides the inside of the container, so that the content capacity can be visually determined. Can not.

Further, when a predetermined amount of ink is appropriately taken out from the ink storage container and used, the amount of ink to be taken out is generally adjusted by using a measuring cup or a measuring cup.

However, it is troublesome to adjust the amount of ink to be taken out from the ink storage container using the measuring cup in this way, and when taking out in an environment without a measuring cup, it is necessary to measure the amount of ink. There was a problem that it became difficult to properly take out a fixed amount of ink.

Further, even if the ink liquid is stored in a transparent or translucent storage container and the container itself is provided with a scale, there is a problem that the above-mentioned ink liquid adheres and conceals.

In the present invention, in order to solve the above-mentioned problems, a low-density polyethylene resin in which an additive having high transparency and imparting high smoothness is blended in the container base material of the ink liquid storage container is used. I decided to use it.

The ink liquid container made of low-density polyethylene with high smoothness has a lower surface tension of the container base material than the conventional ink liquid storage container made of high-density polyethylene. Wetness to the substrate was reduced, allowing the ink to not remain on the inner wall of the container.

In addition, a scale for displaying the content of the ink liquid was provided on the outside of the ink liquid storage container.

Here, when a scale indicating the above-mentioned content is provided in the ink container, it is convenient to install it on both sides of the container when molding the container because the scale portion has an anti-slip effect during use.

In the ink liquid storage container of the present invention, by using low density polyethylene having high transparency and high smoothness for the container base material, the ink liquid does not adhere to the inner wall of the container.

In addition, since it is highly transparent, the content of the ink can be easily confirmed.

Further, in the present invention, since a scale for displaying the content of the ink liquid is provided, an appropriate amount of ink liquid is provided from the ink liquid storage container in which the ink liquid is stored even when there is no measuring cup or when the scale is used. Will be able to be taken out properly.

Further, if the above scale is provided, the content of the ink liquid in the ink liquid storage container can be detected through this scale.

Then, when the scale is molded so as to be arranged on both side surfaces of the container in advance at the time of plastic molding of the container, the scale becomes an anti-slip effect when the ink liquid is taken out, and the container can be stably held.

It is a schematic front view which showed the ink liquid storage container which concerns on embodiment of this invention. It is a schematic left side view which showed the ink liquid storage container which concerns on embodiment of this invention. It is a schematic right side view which showed the ink liquid storage container which concerns on embodiment of this invention. It is a schematic slope view which showed the ink liquid storage container which concerns on embodiment of this invention.

Hereinafter, the ink liquid storage container according to the embodiment of the present invention will be specifically described with reference to the attached drawings. The shape and scale of the container according to the present invention are not particularly limited to those shown in the following embodiments, and can be changed for convenience without changing the gist thereof.

In the ink liquid storage container main body 1 in this embodiment, as shown in FIG. 1, a stroke-shaped bottle having a rounded slope of the shoulder portion 2 or a square-shaped bottle formed into a square shape may be used. In either case, a shape in which the scale can be installed on the side surface of the container is preferable.

Here, low-density polyethylene, which is characterized by high transparency, is used as the container base material of the ink liquid storage container main body 1. Moreover, since the additive that imparts high smoothness is blended, the value of the surface tension of the container base material is lowered. For example, a general low-density polyethylene has a surface tension value of 36 mN / m, but a low-density polyethylene containing an additive that imparts high smoothness is smaller than that value.

Then, in order to impart high smoothness, the inner wall of the container may be coated to impart high smoothness.

Further, a plastic colorant (master badge) may be appropriately used to the extent that the transparency of the container is not impaired during molding of the container.

In the scales 3 and 4 in this embodiment, as shown in FIGS. 2 and 3, a scale showing a well-separated capacity such as a unit of 50 ml along the vertical direction of the outer surface of the ink container and a maximum. A scale indicating a capacity of 180 ml is provided.

It should be noted that the installation location of the scale 3 and the scale 4 is preferably a narrow side surface on which the product label is not affixed.

When the scales 3 and 4 are provided in this way, they are installed so as to be formed on both side surfaces of the container in a convex shape toward the outside or a concave shape toward the inside at the time of molding the container.

When the scales 3 and 4 are installed in this way, the scales have an anti-slip effect when the container is held, and the container can be stably held.
