Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dispensing mechanism of a solid cosmetic dispensing container.

An object of the present invention is to provide a novel container that is inexpensive, has impact resistance, and prevents damage to cosmetics by using a compression spring type coil strip in the feeding mechanism. It is something.

An embodiment of the present invention will now be described with reference to the drawings. FIGS. 1 to 3 show a first embodiment.

Reference numeral 1 indicates an outer cylinder of the cylindrical container, and reference numeral 2 indicates a locking cylinder which is press-fitted and fixed to the tip of the outer cylinder 1.

3 indicates a joint tube that is rotatably inserted into the locking tube 2.

A male thread 3b is threaded on the outer circumferential surface of the joint tube 3, and a protrusion 3c parallel to the circumferential axis direction is formed on the inner circumferential surface.

A small-diameter shaft cylinder 4 extends from the rear end of the joint cylinder 3.

The shaft cylinder 4 is cut from the rear end except for the front part to form a sliding groove 4a.

Moreover, the inner wall surface of the shaft cylinder 4 forms a sliding hole 3d.

A sliding shaft 5 is inserted into this sliding hole 3d, and its tip reaches the joint cylinder 3, and its rear end has a fixing protrusion 5a projecting laterally from the sliding groove 4a of the shaft cylinder 4. It stands out.

The fixing protrusion 5a has a spacer 7 whose rear end is supported by a snap ring 6 fitted into a circumferential groove 4b provided at the rear end of the shaft cylinder 4.
It is slidably inserted between the coil strips 8 made of a compression spring type coil spring inserted between the locking tube 2 and the locking tube 2.

Further, both ends of the coil strip 8 are engaged with the notches 2a and 7a of the locking tube 2 and the spacer 7, respectively, to prevent rotation.

A circumferential groove 5b is provided around the outer periphery of the tip of the sliding shaft 5, and a contact portion 5c at the outer end of the circumferential groove 5b is configured to have a smaller diameter than the sliding shaft 5.

On the other hand, a tail plug 10 having a protruding brush 9 is press-fitted into the other end of the outer cylinder 1, and a bottomed cylindrical cover 11 that covers the brush 9 is removable from the tail plug 10. mated.

The main body of the container is constructed as described above.

Next, the external thread 3b of the coupling tube 3 has an acid screw 12a screwed onto the inner periphery of the end of the mouth tube 12 having a tapered outer periphery.
are removably screwed together.

A cartridge barrel 13 is inserted into the mouth barrel 12 .

The cartridge barrel 13 is held within the mouthpiece 12 by locking a step 13a provided near the mouth end of the cartridge barrel 13 with a lip 12b provided around the inner periphery of the tip of the mouthpiece 12. .

The rear end of the cartridge cylinder 13 is inserted into the joint cylinder 3 so that the protrusion 3C provided in the joint cylinder 3 fits into the groove 13b provided on the rear outer periphery of the cartridge cylinder 13.

As a result, the cartridge cylinder 13 is prevented from rotating relative to the joint cylinder 3.

Reference numeral 14 denotes a core chuck, which includes a rear side piece 14b provided around the sliding plate 14a and a front side piece 14e continuous thereto with respect to several grooves 15 provided in the axial direction of the inner circumference of the cartridge cylinder 13. While being slidably fitted, the front side piece 14
One end of the rod-shaped solid cosmetic a having the same diameter or slightly smaller diameter than the core hole 13c of the IJ tube 13 is fitted into e.

A locking claw 1 is provided at the rear inner end of each rear side piece 14b.
4c, and the distance between the locking pawls 14c is normally larger than the outer diameter of the contact portion 5C of the sliding shaft 5, but smaller than the shaft diameter (see Fig. 3). At the same time, a protrusion 14d protruding from the back surface of the locking pawl 14e is connected to the groove 1.
When the core chuck 14 is pushed inward, the small protrusion 14d that comes out of the locking recess 15b is inserted into the large diameter portion 1
5a to reach the parallel portion 15C, and the rear part of the rear side piece 14b is bent inward against its elasticity.

At this time, the distance between the opposing locking claws 14c is kept smaller than the outer diameter of the contact portion 5C of the sliding shaft 5.
3. Form a cartridge body using the core chuck 14 and the cosmetic material a.

Incidentally, the large diameter portion 15a is formed in order to smoothly attach and detach the locking pawl 14c and the circumferential groove 5b.

In the container configured as described above, first, the outer cylinder 1 is rotated with respect to the joint cylinder 3, and the sliding shaft 5 is fully retracted by the screwing action of the coil strip 8 and the protrusion 5a. In order to hold the cartridge barrel 13 therein as described above (see FIG. 3),
2 is screwed into the joint tube 3, the contact portion 5C of the sliding shaft 5 enters between the engaging claws 14c, the rear end of the side piece 14b contacts the end of the sliding shaft 5, and the core chuck 14 It is slid to the left in the figure.

Therefore, the protrusion 14d comes off from the locking recess 15b, reaches the large diameter portion 15a, and fits the locking pawl 14e into the fitting groove 5b, and when it reaches the parallel portion 15c of the groove 15, it is completely fitted. Become.

In this state, when the outer cylinder 1 is rotated to the right or left, the sliding shaft 5
The core chuck 14 integrated with the core chuck 14 slides inside the cartridge cylinder 13, so that the cosmetic material a enters and exits from the core hole 13c.

When replacing the cartridge body, by removing the mouth tube 12 from the joint tube 3 and pulling it out, the lead chuck 14 moves inside the cartridge tube 13, and the protrusion 14d of the rear side piece 14b fits into the locking recess 15b. At this position, due to the elasticity of the rear side piece 14b itself, the spaces between the locking claws 140 are expanded, the locking claws 14e are disengaged from the abutment portion 5c, and the cartridge body can be taken out.

As described above, the inner shape of the groove 15 provided in the direction of the inner circumferential axis of the cartridge cylinder 13 is such that the large diameter portion 15a and the parallel portion 1
5c is formed in a stepped shape, but the large diameter portion 15a is eliminated and only the parallel portion 150 surface is provided, and the locking recess 15 is formed on this.
It is possible to form b.

In this case, when the core chuck 14 is pushed inward, the protrusion 14d that has come out of the locking recess 15b immediately rides up on the parallel portion 15C, thereby deforming the locking pawl 14c inward.

Next, FIG. 4 shows another embodiment of the present invention,
In this embodiment, the mouth tube 1 of the above embodiment is attached to the front part of the main body constituted by the joint tube 3A which is rotatable with respect to the outer tube 1.
2 and a cartridge cylinder 13) The IJ joint cylinder 13A is removably screwed together, and the cartridge body b/ is constituted by the cartridge cylinder 13A, the lead chuck 14, and the cosmetic material a.

As explained above, the feeding mechanism of the cosmetic container of the present invention is
The fixing protrusion protruding from the sliding shaft side end is screwed between the coil strips that are integral with the main body, and the sliding shaft is moved forward and backward by the screwing action, so fewer basic parts are used. The structure is extremely simple and can be produced at a low cost, and the sliding shaft absorbs shocks such as drops due to the coil strips and is held elastically, thereby preventing cosmetic breakage accidents. It is something that can be done.
