Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator for applying a correction liquid, a paint, a paint, a liquid cosmetic, a powder cosmetic, a drug, a repairing agent, an ink and a paste.

[0002]

2. Description of the Related Art An applicator comprising a container main body having an internal coating agent accommodating chamber and a coating part attached at its tip, and a cap detachably attached to the container main body to protect the coating part,
Conventionally known. By the way, when the applicator is displayed as a product, in order to prevent the surface of the container body or the like from being scratched and the product value from deteriorating, for example, the applicator is put in a plastic bag or put in a blister container. Is being done. In recent years, such as vinyl chloride film, which shrinks when heated, the so-called
The applicator is often packaged using a heat shrinkable film. Since this heat-shrinkable film is in close contact with a product, it has almost no volume as a packaging container, and is advantageous in transportation and cost-effective, and is therefore widely used. The purpose of use of the heat-shrinkable film is to use it as a packaging container for product protection, etc., and to strip off the heat-shrinkable film during use. However,
A method of use has also been proposed in which the heat-shrinkable film is left attached to the container at the time of use by utilizing its adhesiveness. This method of use has the advantage that printing that improves the product appearance can be easily performed. That is, the container body usually has a round or elliptical cross section, and its outer wall has a curved shape. Therefore, when printing a product name, a picture, a pattern, etc. on the container main body, there is a difficulty in printing such as requiring technically high skill and having to perform printing a plurality of times. In comparison, the heat-shrinkable film is flat, so printing on it is extremely easy, and the product is completed by the process of winding the heat-shrinkable film on the container and heating it. Is as good as when printed on a container.

[0003]

However, when using a heat-shrinkable film, a step of covering the product with the heat-shrinkable film and heating it is indispensable. Although the container body and the cap go through the above heating process while being attached, the contraction degree changes depending on the conditions during cooling, and in particular, the fitting between the rear part of the container body and the cap is weakened, causing play. However, in a remarkable case, there was a problem that the cap came off. This problem is the heat shrink film,
Many occur when stripped and used. Unlike this case, in the case of the type used without using the heat-shrinkable film, the heat-shrinkable film absorbs the variation in fitting between the container body and the cap, so that it hardly occurs at the time of manufacturing. However, if the cap is repeatedly attached and detached during use, the heat-shrinkable film will be displaced from the container body, making it unattractive, and as with the above case, the fitting between the container body and the cap will be weak and play However, there is a problem that the cap may come off when it occurs. INDUSTRIAL APPLICABILITY The present invention is an applicator of a type that is used while the heat-shrinkable film is attached to the container even when used, and the appearance may be poor even after long-term use, or the fitting between the container body and the cap may be weakened. The purpose is to provide an applicator that does not.

[0004]

According to the present invention, there is provided a container main body having an interior of a coating agent accommodating chamber and having a coating portion at the tip thereof.
An applicator comprising a cap detachably attached to the container body as a protection of the application part, wherein the container body has a heat-shrinkable film wound around it, and the container body has a small-diameter part for inserting the cap at the rear part thereof. The gist is an applicator characterized in that the applicator is formed and the heat-shrinkable film is also wound around the small diameter portion.

[0005]

In the applicator according to the present invention, since the heat-shrinkable film is wound up to the small diameter portion on the rear portion of the container body, when the cap is inserted into the small diameter portion of the container body, the cap and the small diameter portion of the container body are separated from each other. Since the heat-shrinkable film is sandwiched between the heat-shrinkable film and the container body, the fitting force between the container body and the cap, which is caused by heating or cooling when the heat-shrinkable film is wound around the container body, is prevented, and the step of the container body is prevented. Depending on the part, the heat-shrinkable film does not shift, so that it is possible to prevent deterioration of appearance.
