[Detailed description of the invention] The present invention relates to an IJ type stick-shaped cosmetic container body having a feeding mechanism, and in particular prevents damage to the stick-shaped cosmetic by preventing the feeding mechanism from working when not in use. The present invention relates to a cartridge-type rod-shaped cosmetic container body.

A conventional cartridge-type rod-shaped cosmetic container has a single cylindrical structure, consisting of a main body with a pipe with a spiral groove installed therein, and a block fixed to one end of the grooved pipe including a push rod having a protrusion that engages with the groove. When the user grips the block and rotates the main body, the push rod is extended and the bar-shaped cosmetic material in the cartridge inserted into the block is pushed and exposed.

In conventional cosmetic containers like this, even when the cap is inserted into the block when not in use, the block and main body rotate relative to each other! However, the cosmetic has the drawback that the cosmetic is dispensed into the cap, and the cosmetic may rub against the cap and be damaged.

Furthermore, since the flock is exposed to the outside, stress such as twisting and bending occurs at the joint between the block and the groove pipe.

Furthermore, in such a cosmetic container, since the block is exposed, the feeding mechanism operates even without a cartridge being inserted, which can lead to malfunctions.

Therefore, an object of the present invention is to provide a cartridge-type bar-shaped cosmetic container body in which a block fixed to a groove pipe is installed inside the body, and a feeding mechanism operates only when a cartridge is inserted. It is.

Furthermore, another object of the present invention is to provide a cartridge-type bar-shaped cosmetic container main body in which the dispensing mechanism does not operate when the cap is inserted when the container is not in use.

Furthermore, another object of the present invention is to provide a cartridge type rod-shaped cosmetic container main body which does not cause any strain on the joint between the block into which the cartridge is inserted and the groove pipe.

The present invention basically consists of a cylindrical main body having a dispensing function therein, and a cartridge having a bar-shaped cosmetic material that is rotatably engaged with the main body when inserted therein.
It consists of a block completely installed inside the main body, a push rod having a protrusion that constitutes a feeding function, and a push rod inserted into the main body.
Among a grooved pipe having a vertical groove from which a protrusion protrudes, and a cylindrical pipe having a spiral groove on the inner peripheral wall that engages with the protrusion, one end of the grooved pipe is fixed to a block, and the cylindrical pipe is fitted into the main body. The block is fixed, and the block and the cylindrical pipe are rotatably engaged with each other about an axis.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a cartridge-type rod-shaped cosmetic container main body having a dispensing mechanism according to the present invention.

The main body 1 is cylindrical with an opening on only one side.
A cap 2 is fitted into the opening.

The cap 2 is removably fitted to a cap (not shown), and furthermore, when the cartridge 20 (see FIG. 2) is inserted into the main body 1, the cap 2 is connected to the outer circumferential wall of the container 21 and the This is to engage with the inner circumferential wall of the cap 2 to prevent the container 21 from wobbling.

A vibro, which has a spiral groove 7 threaded on its inner peripheral wall, is fitted and fixed on the inner wall of the main body 1 toward the bottom.

A groove pipe 5 containing a push rod 3 having a protrusion 8 is inserted inside the vibro.

The grooved pipe 5 has a grooved hole 4 in the axial direction, from which a projection 8 projects.

Therefore, the push rod 3 does not rotate relative to the groove pipe, but can reciprocate in the axial direction.

Inside the cylinder 1, a block 12 rotatably engaged with the vibro includes a cylinder part 17 with a leaf spring 15 mounted along its inner circumferential wall, and a cylinder part 17 with its leaf spring 15 mounted in a hole 16 at one end of the vibro. It consists of a small diameter cylindrical body 13 that rotatably fits into the vibro.

The cylindrical body 13 has a hole 14 passing through the center in the axial direction, and is inserted and fixed into the hole 14 of the groove pipe 5.

Therefore, the groove pipe 5 becomes rotatable relative to the vibro.

The other end of the groove pipe 5 has an expanded portion 9, and a washer 10 and a spring 11 are arranged between the expanded portion 9 and the other end of the vibro so as to surround the groove pipe.

Therefore, the block 12 is pressed toward the vibro, and the block 12 and the vibro are reliably engaged.

However, in order to more securely engage the block 12 and the vibro, an annular projection is provided on the outer circumferential wall of the small diameter cylinder 13, an annular groove is provided on the inner circumferential wall of the vibro hole 16, and they are fitted together. Good too.

Since the block 12 is rotatable with respect to the vibro, it is also rotatable with respect to the main body 1.

The cartridge inserted into the opening of the main body 1 is a cartridge that is inserted into the opening of the main body 1.
(Refer to Utility Model Application Publication No. 56-54021) (October 1972)
Any cartridge may be used as long as it has the structure disclosed in the Japanese Patent Application No. 3, 2006 (filed on September 3, 2013).

A longitudinal sectional view of a cartridge having the same structure is shown in FIG.

A rod 23 is housed in a container 21 having a partition 22 in the center and openings at both ends, passing through the center of the partition 22 so as to be slidable in the axial direction.

The outer end of the rod body 23 has a holding portion 2 for storing the rod-shaped cosmetic material 4.
8, and the other end engages with the end A of the push rod 3 protruding from the bottom of the block 12 via a spring 25, and the engagement member slides inside the container 21. Part 25
have.

This spring 26 applies pressure outward in the axial direction to the engaging portion 25 in order to store the bar-shaped cosmetic in the container 21 when not in use.

In this container 21, the holding part 27 and the inner peripheral wall of the container 21 slide, the inner peripheral wall of the hole in the partition part 22 and the rod 23 slide, and the engaging part 25 and the inner peripheral wall of the container 21 slide. This movement allows the rod 23 to reciprocate in the axial direction without wobbling within the container.

FIG. 3 shows the cartridge 20 inserted and the bar-shaped cosmetic 2
FIG. 4 is a cross-sectional view of the cosmetic container showing a state in which cosmetic container No. 4 is drawn out by the amount to be used.

When the cartridge 20 is inserted into the main body 1 through the base 2, the container 2 is
