ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an applicator which contains liquids such as paste, adhesive, shoe polish, cosmetics, etc. and is used by discharging the liquid little by little from the top end with a cap removed.
2. Description of the Related Art
For general applicators, an application face material is attached to the opening of the container containing liquid such as paste, adhesive, shoe polish, cosmetics, etc. therein, and for this application face material, urethane sponge, or sponge with cloths laminated on urethane, or foam rubber sponge is used.
These sponges have effects to discharge a suited volume of a liquid contained in a container.
However, in the applicator of this kind of construction, there were defects in that the application surface was worn out, peeled off, or hydrolyzed and the durability was short.
In addition, in order to improve the durability, there was also a problem in that the manufacturing cost increased.
Furthermore, the convenience of the applicator itself should not be impaired.
Therefore, it is an object of the present invention to provide an applicator which not only provides excellent durability and convenience but also reduces the manufacturing cost by simplifying the manufacturing process.
It is the other object of the present invention to provide an applicator equipped with an application face material which discharges a suited volume of liquid discharged from the container by plastically deforming a plurality of fine filament like portions protrudably mounted on a peripheral area of the top center thereof and achieves further improved durability and smooth application.
It is another object of the present invention to provide an inexpensive applicator by improving still more durability and reducing the manufacturing cost.
Although by another previous invention related to the present invention, a durability of the conventional applicator, which is weak point thereof, had been improved some extent, in order to implement an intention for producing further better products, it is another object of the present invention to figure out the most suitable pattern and design of the fine filament like portion provided on the application face material and it's most suitable diameter or numbers of the holes for discharging the liquid, depending upon the respective applications, through experimental tests using prototype application, so as to make amount of discharged liquid suitable and to provide an applicator for smooth application of liquid.
SUMMARY OF THE INVENTION
The present invention adopts the basic technological configuration as shown below in order to achieve the above-mentioned objects. That is, a first aspect of the present invention relates to an applicator which comprises a container for containing the application liquid and an applicator member of the application liquid which is held to the opening provided at part of the container, wherein the applicator member comprising an application face material and a cover ring for engaging the application face material to the container, and further wherein at least in the center area of the external surface of the application face material, a plurality of flexible fine filament like portions being provided on and protruded from the outer surface of the application face material and at the same time, holes for discharging the application liquid being provided on at least a part of portions formed on said external surface of said application face material and among said plurality of fine filament like portions, and further wherein said application face material and the cover ring being composed of different synthetic resins
In the second aspect of the present invention, an application has such a configuration in that a tip end of the fine filament like portion is directed to the vicinity of the center portion of the applicator member.
