[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a slide type makeup brush and its slide structure.

[0002]

[Prior art]

 Conventionally, the application part (ear tip) of a makeup brush is attached to a slide shaft, and the slide shaft is urged by a spring element and stored in a makeup brush body having both ends opened. When not in use, the body is stored according to the bias of the spring element. And a cap enclosing the extrusion shaft is covered, and when used, the cap is pushed in from the base end side opening of the makeup brush main body to push out the slide shaft in the main body against the bias of the spring element. A sliding makeup brush is known in which a tip attached to the tip of the slide shaft projects from an edge of the tip of the main body. The extrusion shaft contained in the cap is supported by the inside of the top surface of the cap and protrudes in the axial direction.

Here, the slide structure has a characteristic configuration for holding the slide shaft biased by the spring element in a reciprocating manner.

[0004] For example, a slide shaft having a tip attached to a tip thereof, a sleeve for accommodating the slide shaft, and a coil spring which is pressed into a clearance between the slide shaft and the sleeve and biases the slide shaft in the retreating direction toward the base end. A makeup brush body consisting of a cylindrical body to which both ends are opened and sleeves are fitted and fixed together with a slide shaft, and a cap that contains an extrusion shaft protruding in the axial direction. The cap is opened at the base end side of the makeup brush body. The slide shaft is pushed out of the main body by pushing in from the main body, and the tip attached to the front end of the slide shaft is configured to protrude from the rim on the main body front end side.

[0005]

[Problems to be solved by the invention]

 However, it is necessary to structurally improve the stability of the repetitive operation (movement) concerning the press-fitting of the coil spring and the definition (limitation) of the reciprocating range of the slide shaft, and the workability of assembling the slide shaft and the sleeve. There was a point. In this case, simplification and robustness of the structure are also required.

[0006] In particular, the problem of structural deterioration before the life of the brush due to repeated use, such as the spring jumping out of the main body during use, or the fact that a part of the tip is entangled with the spring and bent and the tip of the Problems were often pointed out, such as damage to the part) or the rattling of the slide axis gradually.

[0007]

[Problems to be solved by the invention]

 SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and aims to solve the above-described problems and provide a slide-type makeup brush that can be easily and stably used repeatedly and a slide structure thereof. .

The inward flange is locked and the rear end is locked by a protruding piece to limit the range of expansion and contraction. The sleeve is held in a retractable manner, and the sleeve guides the projection and has a slide hole defining a reciprocating range of the slide shaft including the projection, and is housed in the cylinder body. The tip is opened so that the tip can protrude and retract from the edge, and the outward flange of the sleeve base end opening is locked to the base end opening edge. It is characterized by being covered so as to cover the edge.

In the slide structure, the slide shaft is made of resin and is formed in a bat shape having a constricted portion having a gradually decreasing cross-sectional diameter partially directed toward the base end side, and a protrusion is formed on the constricted portion. The piece is integrally molded, a coil spring is wound around the body part, the front end of which is locked to the inward flange of the opening on the tip side of the sleeve, and the rear end is locked by a protruding piece to limit the range of expansion and contraction. The spike is reciprocally movable in the sleeve against or against the bias of the coil spring, and the ear tip is held so as to be able to protrude and retract from the main body. The sleeve is made of resin and guides the protruding piece. A slide hole that defines the range of reciprocation of the slide shaft including the projecting piece is housed in the cylindrical body. When the slide shaft and the sleeve are assembled, a slide spring on which a coil spring is wound is used. The insertion shaft is inserted from the base end side opening of the sleeve, and the opening edge of the sleeve is elastically deformed to press-fit the protruding piece, floated and locked in the slide hole, housed in the sleeve and fixed. It is characterized in that the expansion and contraction range of the spring is limited within the sleeve.
