Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an adhesive applicator, and more particularly to an adhesive applicator useful for a surface to be applied having a curved surface such as a pipe or joint made of vinyl chloride.
[0002]
[Prior art]
When connecting pipes and fittings made of vinyl chloride with vinyl chloride adhesive, the number of brushes used for applying adhesive increases as the diameter increases because the brush application area is small. Must be applied in batches. However, since the vinyl chloride adhesive is quick-drying, it actually dries during several times of application, making it difficult to connect with the adhesive.
Also, with conventional brushes, there is a restriction on the direction of application that the brush cannot be applied unless the brush is almost upright with respect to the surface to be coated. Therefore, the brush is applied by making a round around the axis of the tube or joint. However, even when the work space is secured, it is troublesome, and when the work space is secured only on one side, there is a defect that the coating itself cannot be performed.
[0003]
[Problems to be solved by the invention]
The problem to be solved is that adhesion can be applied quickly and reliably even if the pipes and joints are thick, and even if the working space is only secured on one side, it can be applied reliably and has a superior advantage in use The object is to provide a material applicator.
[0004]
[Means for Solving the Problems]
To achieve the above object, the present invention provides an adhesive applicator that can be detachably provided in an opening of an adhesive container, wherein the applicator main body has a coaxial proximal handle portion and an intermediate plug. The handle portion is formed on the outer side of the opening portion so that it can be gripped in a state in which the handle portion is detachably provided in the opening portion, and the plug portion is formed in the opening portion. And the opening can be closed in a sealed manner , the outer diameter is made larger than the diameter of the handle, and the pushing surface is formed on the top surface of the stopper. The fiber is radially developed from the spherical center, and has a spherical shape having a large number of adhesive holding gaps between adjacent radial fibers, and the coating surface is formed by a spherical surface. .
[0005]
Here, the above-mentioned spherical center is the center of the sphere. And the applicator main body in this invention may be the same molded article except an application part, and is good also considering a pattern part and / or a plug part as a separate combination aspect. Further, the material of the applicator main body may be made of synthetic resin such as polypropylene or plastic, wooden or metal, or other materials except for the application part. For example, only the stopper may be made of rubber. The fibers forming the application part may be either straight fibers or crimped fibers, and the material is preferably a synthetic fiber such as polypropylene fiber.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 illustrates an embodiment of the adhesive applicator according to the present invention. The applicator main body 1 includes a coaxial base handle 2, an intermediate plug 3, and a front coat. 4 is configured. The handle portion 2 is formed in a rod shape that is easy to grip, and is positioned outside the opening portion 5a in a state where the plug portion 3 is detachably fitted to the opening portion 5a of the adhesive material container 5. is there. The finger pad 2a in the handle 2 may be omitted. The handle part 2, the plug part 3, and the collar part 1a are integrally molded products made of polypropylene.
[0007]
The plug portion 3 is formed in an inverted truncated cone shape that can be attached to and detached from the opening portion 5a and can close the opening portion 5a in a sealed manner. Further, the plug portion 3 has an outer diameter larger than the diameter of the handle portion 2 and is formed with a pressing surface portion 3a on the upper surface portion of the plug portion, so that a finger is pressed against the pressing surface portion 3a. The capping operation is easy.
[0008]
The coating portion 4 has a spherical shape, and a spherical surface is formed as the application surface 4a. The application surface 4a made of a spherical surface is formed at the tip of each fiber 4b that is radially expanded from the spherical center. A large number of adhesive holding gaps 4c are formed between the radially adjacent fibers 4b so as to communicate with the coating surface 4a. Each fiber 4b is made of polypropylene, and has a radial shape by being bound by a wire 4d such as a wire at a spherical center portion. The coating portion 4 is integrally fixed by fixing the wire 4d to the tip of the flange portion 1a extending from the plug portion 3 in an embedded state.
[0009]
The collar part 1a is formed in a tapered shape so that the application surface 4a formed of a spherical surface can secure the maximum area, and the length of the collar part 1a is set in a closed state so that the coating part 4 is an adhesive container. 5 is formed to have a length ratio that reaches the bottom near the bottom, so that the adhesive is surely held in the multiple adhesive holding gaps 4c between the application surface 4a and each fiber 4b at the time of closing so that it can be prepared for application. It is.
[0010]
【The invention's effect】
A. According to the first aspect, the application surface is a spherical surface, and a plurality of adhesive material holding gaps 4c that are radially developed from the vicinity of the spherical center are held between the fibers forming the application surface made of the spherical surface. Therefore, the application area of the application surface is large, and the restriction on the application direction is kept to a minimum, so that even if the pipes and joints are thick, it can be applied quickly and reliably, and the work space is reduced. Even if only one side is secured, it can be applied reliably and has a superior advantage in use.
Further, when closing the plug, the opening can be easily closed by pressing the finger against the pressing surface of the plug.
