Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll-on type external preparation for external application for applying a liquid or fluid semi-solid skin treatment agent to the skin.

[0002]

2. Description of the Related Art Conventionally, a roll-on type external preparation for skin intended to be applied to the skin such as deodorant lotion has been known.

As a container structure for such a roll-on type external preparation for skin, as shown in FIG.
In addition, the spherical roll 83 for adjusting the discharge amount of the skin treatment agent 82
It is known that they are fitted together. In the case of the roll-on type external preparation for skin having the container structure of FIG. 8, the container 81 is inverted and the skin treatment agent 82 is supplied to the gap between the spherical roll 83 and the opening A by gravity or surface tension, and in that state, the spherical roll 83 Is pressed against the skin and the container is moved along the skin to continuously apply the skin treatment agent to the skin.

As another container structure for a roll-on type external preparation for skin, as shown in FIG. 9, a spherical roll 93 for adjusting the discharge amount of the skin treatment agent 92 is fitted into the opening A of the container 91, Further, a tube 94 for attaching a skin treatment agent to the gap between the opening A and the spherical roll 93 is attached to the opening A, and the tip of the tube 94 is immersed in the skin treatment agent 92. Are known. In the case of the roll-on type external preparation for skin having the container structure of FIG. 9, the outer wall 91a of the container 91 is manually pressed, and the skin treatment agent 92 is supplied to the gap between the opening A and the spherical roll 93 through the tube 94 by the pressure. Then, in this state, the spherical roll 93 is pressed against the skin, and the skin treatment agent 92 is continuously applied to the skin by moving the container along the skin.

[0005]

However, in the case of the roll-on type external preparation for skin having the container structure shown in FIG. 8, unless the container 81 is inverted, the skin treatment agent, which is the content, is added to the spherical roll 8.
However, there is a problem in that it is very difficult to apply the skin treatment agent to the back side of the lower jaw, the axilla and other downward facing portions. In addition, when the content has a high viscosity, the roll is not smoothly driven, and it is difficult to uniformly apply it to the skin.

Further, in the case of the roll-on type external preparation for skin having the container structure shown in FIG. 9, since this was originally developed for the purpose of uniformly applying the emulsion, the content is more than that of the emulsion. In the case of a highly viscous gel, cream or paste, a high grip force is required for pressing, and there is a problem that it is very difficult for an infant, a woman or an elderly person with a small grip force to handle. There is also a problem that the contents cannot be supplied to the spherical roll when the container 91 is inverted.

The present invention is intended to solve the problems of the prior art as described above, and a roll-on type external preparation for skin has a relatively high viscosity regardless of whether the container is in an upright state or an inverted state. The purpose of the present invention is to make it possible to easily apply a high skin treatment agent.
