Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multicolor toothpaste filled in a single dispensing container such as an extruded tube, which has a clear attractive striped pattern (stripe pattern) when extruded onto a toothbrush or the like. ) Expressing multicolor toothpaste.

[0002]

2. Description of the Related Art The appearance of a striped pattern has a visual effect that makes it look beautiful and also draws attention. In the field of dentifrices, multicolor toothpaste that has a striped pattern when extruded is on the market as a product that takes advantage of such aesthetics and attractiveness. A color combination is generally composed of a white toothpaste portion and a colored toothpaste portion other than white (hereinafter referred to as a colored toothpaste portion). A white pigment such as titanium oxide is used for the white toothpaste portion, and a pigment such as ultramarine blue is used for the colored toothpaste portion.

However, even in multicolor toothpaste, an abrasive is an essential component, and a large amount of abrasive such as calcium carbonate, calcium phosphate, and silicic acid anhydride is mixed.
A dentifrice composition containing a large amount of these abrasives not only becomes opaque but also tends to largely lose the sharpness of color expected from the above-mentioned pigments. Therefore, in the conventional multicolor toothpaste, there is room for further improvement in aesthetics and the like.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a multicolor toothpaste that provides vivid colors and develops an attractive stripe pattern.

[0005]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that adding a water-soluble copper compound to a multicolor toothpaste improves the sharpness of stripes. Heading out, the present invention was completed.

[0006] That is, according to the present invention, in a multicolor toothpaste filled in a single dispensing container and comprising at least two toothpaste portions, one toothpaste portion of one of the two adjacent toothpaste portions is The transparency is 0.5 to 30 mm, the transparency of the other toothpaste portion is 0 to 0.2 mm, and at least one of the toothpaste portions of at least two colors contains a water-soluble copper compound. A multicolor toothpaste is provided.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the multicolor toothpaste of the present invention, in two adjacent colored toothpaste portions, the transparency of one colored toothpaste portion is 0.5 to 30 mm, preferably 1 to

By using these water-soluble copper compounds, there is little discoloration,
A multicolor toothpaste with good color development can be obtained. Further, these water-soluble copper compounds can be used in combination with other water-soluble colorants.

A water-soluble coloring agent can be preferably used as the coloring agent for the low-transparency toothpaste portion of the multicolor toothpaste of the present invention, but a small amount of water-insoluble coloring can be used as long as the transparency is kept within the above range. Agents (pigments) can also be used.

The multicolor toothpaste of the present invention has at least two colors. The combinations of the colors are as follows: white and blue, white and pink, white and red, white and green, white and pink. In addition to combinations of white and other colors such as colors and blue, white and red and green, combinations of colors that do not include white such as red and green, pink, green and blue, and the like are exemplified.

In the case of the present invention, as the white toothpaste portion, a low transparency toothpaste containing a small amount of white powder (white pigment) such as titanium oxide, calcium compound or magnesium compound can be preferably used. The non-white toothpaste part is a highly transparent toothpaste containing a water-soluble coloring agent or a low-transparency toothpaste containing a small amount of a water-soluble coloring agent and a transparency control agent (titanium oxide, calcium compound, magnesium compound, etc.). Etc. can be used.

The multicolor toothpaste according to the present invention is manufactured by filling a single container such as a tube so that the toothpaste portions constituting the multicolor toothpaste do not mix with each other. Such a multicolor toothpaste product can be produced by various conventionally known methods as shown below and is not particularly limited. (1) Filling one tube with multicolor toothpaste so that they do not mix, (2) Fitting a ring-shaped pocket containing toothpaste on the tube shoulder, and then base the entire tube A method of filling a toothpaste consisting of the following and discharging the toothpaste of the base to introduce another toothpaste through the hole provided in the pocket to form a stripe pattern, (3) Providing one or more partition walls on the tube, respectively. Method of filling toothpaste of different colors in the part of (4), method of adhering two or more tubes filled with toothpaste of different colors to form one tube.
