Description

[Detailed description of the invention] The present invention has a unit structure of a cosmetic extrusion mechanism with two strong and weak springs inserted into the outer shaft cylinder serving as a holder, and the unit structure is used when using or not using cosmetics. Perform a haunting. It relates to so-called double-knot style cosmetic tools, and its purpose is to make it convenient for frequent use by allowing cosmetics to be immersed in hygienically without staining hands, and to ensure that the cosmetics remain in a state that they do not appear. Another object of the present invention is to simplify this type of extrusion mechanism and provide a trouble-free cosmetic tool.

Hereinafter, the drawings showing the embodiments of the present invention will be described. Fig. 1 is a longitudinal cross-sectional view of the entire cosmetic tool in a usage state in which the unit structure is pushed out and the cosmetic product is protruded by operating the knob, and Fig. 2 is a partial sectional view of the cosmetic tool when not in use with the unit structure recessed in the extruded state, A is the outer shaft cylinder of the cosmetic tool, B is the extrusion unit structure of the cosmetic extrusion mechanism, and C is the elastic locking piece. .

The outer barrel A is the upper barrel 1 which mainly serves as a holder.
and a tip tube 2 having a central hole at the lower end as an extrusion port 2a are connected by screwing together, press-fitting, or other appropriate fixing means. A small window hole 3 is opened in a part of the upper outer circumferential surface of the upper shaft cylinder 1, and a center hole 4 is opened in the upper end surface, respectively. The upper end is formed to protrude outward so that the cosmetic extrusion unit structure B can be pressed down from the outside.

C is an elastic locking piece with an annular part 6 at its upper end, which is forcibly fitted while abutting against the top surface of the center hole 4 of the upper shaft cylinder 1, or fixed with adhesive as appropriate; A narrow plate spring-like locking piece 6a is integrally provided at a portion of the lower edge of the portion 6 and brought into elastic contact with the inner circumferential surface of the upper shaft cylinder 1. Further, a push button 7 is provided approximately in the middle of the locking piece 6a, and this button protrudes from the small window hole 3 to the outside so that it can be retracted from the outside against the elasticity of the locking piece 6a. The locking piece 6a excluding the portion 6 is tilted inward greatly as it reaches the lower end, and is disengaged from the upper end 17 of the short tube 19, which will be described later, and is engaged with the inner bottom surface 18 of the short tube 19 to form the second
As shown in the figure, the cosmetics 21 are immersed into the tip 2.

Next, the extrusion unit structure B for cosmetics is a push-down tube 9.
The upper end of a lead chuck 11 having a chuck 11a for mounting a fastening ring 10 on the lower end thereof is fixed.The lead chuck 11 is attached by penetrating the center hole of a fixed cylinder 12 connected to the lower end of the push-down tube 9.
The fixed tube 12 has a chuck cover tube 13 fixed to the lower side of the flange 12a, and accommodates the chuck 11a with the fastening ring 10 attached in the center hole thereof, and further has a tube tube 14 of a slightly larger diameter attached to the upper side of the flange 12a. The lower end is fixed and the push-down tube 9 is installed inside, and a coil spring 15 is attached to the fixed tube 12 and the push-down tube 9 with the upper and lower ends serving as receiving portions, whereby the push-down tube 9 can be moved back and forth.
That is, the chuck 11a is provided in such a way that it can be clicked, and the chuck 11a is operated to open and close. The push-out rod 16 is formed so as to be able to protrude a certain length as the chuck 11a is opened and closed.

Such a cosmetic extrusion unit B has a short tube 19 inserted into the upper end of the tube tube 14 with a slight gap 8 between it and the inner peripheral surface of the outer barrel 1 of the cosmetic tool to allow free movement in the axial direction. The upper end 17 and inner bottom 18 of the tube 19 are alternately locked by the leaf spring locking pieces 6a of the elastic locking pieces C to maintain the cosmetic extrusion unit B in its retracted position. The cosmetic extrusion unit B thus integrally assembled is inserted into the upper shaft cylinder 1 so as to be movable in the axial direction, and the lower side of the flange 12a of the fixed cylinder 12 connected to the lower side and the tip cylinder 2 are inserted. Step part 2 of inner peripheral wall
A coil spring 20 whose upper and lower ends are received in the upper and lower ends is housed using a coil spring 20 whose elasticity is weaker than that of the coil spring 15, and the cosmetic extrusion unit structure B is always attached to the rear of the shaft by the spring action of the coil spring 20. to strengthen The role of this coil spring 20 is only to support the cosmetic extrusion unit B in the upper shaft cylinder 1 with a lower elasticity than the coil spring 15 of the cosmetic extrusion unit B, and as shown in FIG. When the push-down tube 9 is pushed down by compressing the coil spring 20, the lower end locking end 6b of the elastic locking piece C is locked to the upper end 17 of the short tube 19 to prevent it from retreating and maintain the push-out position. As shown in Fig. 2, when the push button 7 is pushed into the upper shaft cylinder 1, the locking end 6b tilts inward, so that it is forcibly removed from the upper end 17, and the cosmetic extrusion unit B is pulled out by the coil spring 20.
is pushed up above the shaft and retracted, and the locking end 6b of the elastic locking piece C locks on the inner bottom surface 18 of the short tube 19 to maintain the retracted state. In this way, the push-down operation and push-button push-in operation are repeated to push out and retract the cosmetic push-out unit B.

Next, the lower end 16a of the push-out rod 16 is a connecting part provided at the tip of the push-out rod 16, and always protrudes downward from the chuck cover tube 13, and a screw is engraved therein or a magnet piece is fixed to the receiving tube of the cosmetic 21. 21b is fixed. That is, the cosmetic product 21 is attached by using a rod-shaped solid product 21a and fitting the rear end into the receiving tube 21b. To replace the cosmetic product 21, the extrusion rod 16 is protruded from the extrusion port 2a of the tip tube 2, and the cosmetic product 21 is replaced with a spare item 22 housed in the upper end 9a of the extrusion tube 9. still,
The spare cosmetics 22 are inserted from the knob cover 23 side by arbitrarily partitioning the rear end of the push-down tube 9. 24 in the drawing is a stopper provided at the upper end of the push rod 16;
To prevent the push rod 16 from coming off. Reference numeral 25 denotes an elastic holding tube for the push rod 16, which is made of elastic rubber and is fitted and fixed into the center hole of the chuck cover tube 13, and constantly contacts the outer periphery of the push rod 16 to prevent the push rod 16 from falling under its own weight and retreating. . Further, the locking step portion 17, inner bottom surface 18, etc. of the short tube 19 described above may be provided with a cushioning material to absorb shock.

In the present invention, as described above, the extrusion unit structure B of the cosmetic product is extended and retracted by repeating the depressing operation of the push-down tube 9 and the push-in operation of the push button 7. After use, the present cosmetic device In addition, it can be stored in the shaft cylinder while attached to the receiving cylinder 21b, making it hygienic to use. It can also be used again by pushing it out as it is, and in the protruding state, the elastic locking piece C is forcibly released. The structure of the extrusion unit for cosmetics can be maintained as long as the unit is not in use, so it is robust and reliably maintained against movement in the axial direction.On the other hand, the means for releasing the locking state is also smooth and quick with a slight pushing operation of the push button 7. Body B can be immersed therein, and since the extruded unit structure B for cosmetics is formed as a unit part in advance, sufficient inspection can be performed and a product without failure can be obtained.Furthermore, the overall assembly structure can be simplified and work efficiency can be improved. There are many benefits such as increasing
