Abstract

(57) [Summary] [Purpose] A conventional liquid applicator is made separately from a coating surface material and a cover ring for attaching the coating surface material to a container. I was attached. It is therefore an object of the present invention to provide an inexpensive and easy-to-use applicator by further improving the durability and reducing the production cost. The coating member attached to the container 1 is formed by fitting a coating surface material to a cover ring, and a plurality of needle-like protrusions such as wool are formed around the center of the top of the coating surface material. A mountain is provided, and a plurality of small holes are formed between the ridges and the valley between the ridges. The outer peripheral portion of the ridge forms a non-peripheral zone of the protrusion and the small hole. A two-color injection molding method for simultaneously or successively injection-molding the two-color or two kinds of synthetic resin raw materials with the coating surface material and the covering in a coating device for attaching a cap to a container so as to cover the coating surface material. It is characterized by being integrally molded.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a liquid applicator that is used by containing a liquid material such as glue and adhesive, shoe ink and cosmetics.

[0002]

[Prior art]

 The application surface of a conventional liquid applicator is made using a sponge of urethane or the like, a sponge in which a cloth or the like is laminated on urethane, or a sponge of a protective film for foaming. Therefore, the coated surface was worn, swelled, hydrolyzed, and had a problem in durability. Therefore, in order to improve the durability, which is the greatest weakness of the conventional product, as described above, the inventors have previously devised several cases other than Japanese Patent Application No. Hei 8-2488.

[0003]

[Problems to be solved by the invention]

 With the several ideas made earlier, we were able to provide a highly convenient applicator in addition to significantly improving the durability, which is a weak point of conventional products. However, from the perspective of providing better products, the aim is to provide an inexpensive applicator with improved durability and reduced manufacturing costs this time.

[0004]

[Means for Solving the Problems]

 The coating member attached to the container is formed by fitting a coating material to a covering, and a number of needle-like protrusions such as wool are provided around the center of the top of the coating material. A plurality of small holes are formed between the ridges and the valleys between the ridges, and the outer peripheral portion forms a peripheral zone without the ridges and the small holes. In an applicator in which a cap is attached to a container so as to cover the coated face material, a two-color injection molding method for simultaneously or continuously injection-molding the coated face material and the covering with two or two kinds of synthetic resin raw materials. It is used as a means to solve the problem by making it integrally molded.

[0005]

[Action]

 The coating surface material of the applicator according to the present invention has a large number of needle-like protruding peaks, such as wool, protruding around the center of the top, and discharges a solution between the protruding peaks and the valley between the protruding peaks. A plurality of small holes are formed, and an outer peripheral portion around the center of the top forms a protruding ridge and a peripheral zone without small holes. In the applicator in which the coated face material formed in this way is fitted to the cover ring and attached to the upper part of the container, and then a cap is attached so as to cover the coated face material, the coated face material according to the present invention includes: Since they are integrally molded by the two-color injection molding method, they can be directly mounted on the upper part of the container without any post-processing. According to this two-color injection molding method, an extremely stable molded product can be obtained because the contact surface between the coated surface material and the covering made of two different kinds of raw materials is melt-bonded at the time of molding.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall explanatory view of an applicator. A cap 2 is attached to an upper portion of a container 1 for holding a liquid application liquid, and a male screw 10 for guiding the cap to a desired position is provided around the cap. Further, on the upper portion of the male screw 10, there is provided a coating member A formed from a covering 3 and a coating surface material B integrally formed by a two-color injection molding method. The coating surface material B is provided with a large number of protruding peaks 5 having a needle-like shape such as a wool, and a plurality of small holes are formed in a valley between the protruding peaks. The outer peripheral portion around the central portion of the top is formed by a protruding ridge and a non-peripheral edge portion 4 of a small hole. A member denoted by reference numeral 2 is a cap that is attached to the container so as to cover the coating portion A, and a female screw (which is screwed to the male screw 10 provided around the upper part of the container) is provided below the inside of the cap. (Not shown) are provided around.

FIG. 2 is a view for explaining a cover ring 3 attached to the upper part of the container, and a coating surface material B integrally formed with the cover ring by two-color injection molding. The cover ring is made of a hard synthetic resin and the coated surface material is made of two materials different from the soft synthetic resin. However, since it is made by a two-color injection molding method, the contact surface 8 is melt-bonded in a stable state during molding. Have been. A female screw 7 to be screwed into the container is provided around the inner side of the cover ring, and the coated surface material is composed of a number of protruding peaks 5 having a needle-like shape such as a wool, and a valley between protruding peaks. Is formed around a central portion of a top through which a plurality of small holes penetrate, and an outer peripheral portion around the central portion of the top is formed with a peripheral portion 4 having neither a protrusion nor a small hole and a sliding surface.

FIG. 3 is a view showing a state in which a cover ring integral with the coating surface material described with reference to FIG.

[0009]

【effect】

 As described above, according to the present invention, a large number of needle-like protrusions such as wool are provided around the central portion of the top, and a plurality of small holes for discharging the solution penetrate between the protrusions. The outer surface of the coating is a two-color injection molding method that integrates the coated surface material, which is a peripheral band with no protruding ridges and small holes, and a cover ring that serves to incorporate and apply the coated surface material to the container. Since it is a molded product, it can be directly assembled into a product without any post-processing. According to the two-color injection molding method, an extremely stable molded product can be obtained because the contact surface of the coating surface material and the covering made of two different kinds of raw materials is melt-bonded at the time of molding. Not only durability is ensured, but also the work of incorporating the coating surface material and the separate covering as in the conventional product can be omitted, so that the production cost can be reduced and an inexpensive applicator can be provided.
