Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to medical, cosmetic, office, cooking,
A liquid that contains a liquid for machining, cleaning, etc., and is provided with a coating member, and can apply the liquid accurately and effectively to a portion to be coated such as a living body, office paper, a cooking tool, a machine, or a body to be cleaned. It relates to an applicator.

2. Description of the Related Art Conventionally, for example, there are a medical solution applicator that stores a solution and includes an application member, one having a brush on a cap of a container, and another having an application member in a container. In the former case, handling is cumbersome and a hard brush tip irritates the affected area, making it difficult to use. The latter is easy to handle and easy to use, but requires a certain degree of squeezing (drawing deformability) in the container body in order to enable the liquid agent to be extruded from the application member. For this reason, as a conventional medical liquid applicator, a medical liquid applicator provided with an applying member in a container formed of squeezable plastic or the like is frequently used.

However, in the medical solution applicator provided with an application member in the above-described conventional container, since the material of the container is limited to a squeezable material such as plastic, in addition to the strength against the sterilization process, volatile solvents and Prevention of evaporation of volatile chemicals,
It is not possible to use a glass container having a great advantage in terms of drug adsorption and the like.

In addition, in order to provide a small-capacity container with the squeezing characteristic of plastic, it is necessary to make the container body thinner or made of a soft material as compared with a large-capacity container. However, since the ratio of the surface area to the volume of the container is inversely proportional to the 1/3 power of the volume, the smaller the capacity, the larger the ratio of the surface area to the capacity. This means that the transpiration rate per volume is higher in the small volume container. In order to obtain the same transpiration rate, a small container with a capacity of 1 ml should have a wall thickness 2.15 times that of a large container with a capacity of 10 ml, or a container material with a lower permeability (and consequently a harder material). I have to choose. Therefore, in order to obtain a small-capacity plastic container made of squeeze, it is necessary to make the container thinner or softer than in a large-capacity container. With the contradiction that it must be made of a thicker or harder material. That is, in the medical solution applicator provided with an application member in the above-described conventional container, it is difficult to reduce the capacity of the container in order to secure a certain evaporation prevention function.

JP.U.57-184781 discloses "an applicator in which a tip valve having an applicator fixed to the tip thereof is pressed against an application liquid chamber opening so that the applicator projects." However, in this prior art, when the liquid is applied by the application body, the application body and the tip valve are always in a pressed state,
The opening of the coating liquid chamber is left open, so that the liquid continues to flow out, and more liquid than necessary is discharged. In other words, it is not possible to exude only a certain amount of liquid and apply the liquid by stretching it thinly.

The present invention uses a container made of a strong and hard material and having an arbitrary capacity to allow a liquid contained in the container to smoothly and leaching into the outer surface of the container of the coating member by a certain amount, and to accurately apply the liquid to the portion to be coated. It is intended to be able to be applied effectively.
