Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a rod-shaped cosmetic dispensing container that is a cartridge type cosmetic product.

``Prior art'' This type of dispensing container has an upper half of the main cylinder as a medium cylinder with a small outer diameter, a rotary cylinder fitted on the outer surface of this medium cylinder, and a tray for holding cosmetics that can be raised and lowered in the medium cylinder. This saucer is inserted into the inner cylinder through a longitudinal guide hole provided in the middle cylinder using a protrusion, and is engaged with the screw groove on the inner surface of the rotating cylinder, and the main cylinder and the rotating cylinder are rotated in relatively opposite directions to dispense cosmetics. Carrying out and feeding operations.

Several cartridge-type containers for cosmetics have been proposed as containers of this type. A typical example is that instead of holding cosmetics directly on the tray,
This saucer is held through an inner plate that is removably engaged with the inner plate, and the inner cylinder of the main cylinder is provided with a guide hole for the inner plate at the upper end in addition to the one for the saucer. The structure is such that the inner plate is forcibly moved further from the lower end retracting position to disengage the inner plate, and then the saucer is fed out to the upper end to push the inner plate outward, and the inner plate is replaced in this state. be.

``Problems to be Solved by the Invention'' The above-mentioned conventional method is a system in which the inner tray, which directly holds the cosmetics and is fitted into the receiver tray, is replaced. In this case, the following points become a problem.

That is, since the inner tray is required to operate integrally with the saucer at all times, it is firmly fitted into the saucer. For this reason, when replacing the new inner plate, the new inner plate must be forcibly pushed into the saucer and fitted, but since the saucer can be raised and lowered, the main cylinder and rotating cylinder must be firmly held to prevent the tray from descending. , the exchange operation becomes troublesome.

In addition to the saucer guide hole, a pair of medium plate guide holes are drilled in the middle cylinder, but since this medium plate guide hole is passed through to the upper end of the middle cylinder, the top middle cylinder is divided into two, and as described above. There is a risk that the inner tube may become deformed due to strong pushing when replacing the inner plate.

The object of the present invention is to provide a novel cartridge-type, rod-shaped cosmetic dispensing container that solves these problems.

"Means for Solving the Problems" The bar-shaped cosmetic dispensing container of the present invention has a middle cylinder 7 with a slightly smaller outer diameter standing upright from a lower base cylinder part 6, and a middle cylinder 7 with a slightly smaller outer diameter on both sides of the middle cylinder 7. The main cylinder 1 has elongated guide holes 8, 8 leading to it, and a screw 9 on the inner periphery of the upper part.
Two symmetrical threaded grooves 10, 10 are formed on the inner surface of the lower half, and are fitted onto the outer surface of the middle cylinder 7 and extend upward from this, relative to the main cylinder 1 when dispensing and feeding the cosmetics. Rotating tube 2 that is rotated in the opposite direction
and an elevating tube 3 in which engaging protrusions 11, 11 protruding from both sides of the outer surface are engaged with the screw grooves 10, 10 through the guide holes 8, 8, and rise when dispensing cosmetics and descend when feeding cosmetics; A reinforcing cylinder 4 is removably screwed onto the inner surface of the upper part of the rotary cylinder 2, like an upward extension of the middle cylinder 7, and a reinforcing cylinder 4 is housed inside the auxiliary cylinder 4 so as to be movable up and down, and is normally pushed downward by a spring 12. It consists of a receiving tray 5 for holding cosmetics 13 which is pushed up by the elevating cylinder 3 which is biased and rises against the spring 12 when being fed out.

"Function" In the above, the elevator cylinder 3 is normally used as shown in Figure 1.
is retracted into the middle cylinder 7, and the saucer 5 is pushed down to the lower end of the auxiliary cylinder 4 by the spring 12, and in this state the cosmetics 13 are stored in the auxiliary cylinder 4.

Here, when applying makeup, the main cylinder 1 and the rotary cylinder 2 are relatively rotated in a predetermined direction. Then, in the elevating tube 3, the protrusions 11, 11 are aligned with the screw grooves 10, 10.
However, since the protrusions 11 and 11 are simultaneously engaged with the guide holes 8 and 8 of the middle cylinder 7, the elevating cylinder 3 eventually moves upward due to the above relative rotational movement. This movement pushes up the saucer 5 and therefore the cosmetics 13 upward against the spring 12.
Extend the auxiliary cylinder 4 outward. After applying makeup, the operation can be performed in the opposite manner to the above.

However, when the cosmetic product 13 becomes worn out or broken, the auxiliary cylinder 4 can be screwed back from the rotary cylinder 2 and removed, and the assembly of the auxiliary cylinder 4, the saucer 5, and the spring 12 can be replaced.

``Example'' The example shown in Figures 1 and 2 is the same as that described in the ``Means for solving the problem'' mentioned above, and in order to avoid duplication, this previously described part is Explanation will be omitted, and only matters not mentioned above will be explained.

The base cylinder 6 of the main cylinder 1 is cup-shaped, and a large number of shallow grooves 14 are provided on the outer surface in the circumferential direction to prevent slippage. Incidentally, the height of the middle cylinder 7 is approximately half that of the rotary cylinder 2.

The rotary cylinder 2 is attached so that the groove on the inner periphery of the lower end engages with the protrusion 15 on the outer periphery of the lower end of the middle cylinder 7 so as not to come off.

The elevating tube 3 has dimensions such that its upper end is approximately the same as the upper end of the middle tube 7 when it is retracted.

The auxiliary cylinder 4 connects the screw 16 on the upper outer surface with the screw 9.
It is screwed onto the inner surface of the upper half of the rotary cylinder 2, and there are locking protrusions 17 and 18 on the inner circumference and the lower end.
is established.

The saucer 5 is installed inside the auxiliary cylinder 4 by a locking protrusion 19 on the outer periphery of the lower part, and is constantly urged downward by a coil spring 12 inserted between this protrusion 19 and a protrusion 17 at the upper end of the auxiliary cylinder 4. , located directly above the elevator tube 3.

The assembly of the auxiliary cylinder 4, saucer 5, and spring 12 becomes a replacement part. In the figure, 20 is a cap, and 21 is a virgin seal, which are glued so as to close the opening at the upper end of the auxiliary cylinder 4. It is preferable that this virgin seal 21 be transparent, but it is of course not necessary to provide it.

Each of the above parts, except for the screw 12, is molded and manufactured from a synthetic resin material.

"Effect of the invention" As described above, in the present invention, the auxiliary cylinder 4 is removably installed in the upper part of the rotating cylinder 2, and the spring 1 is attached to the auxiliary cylinder 4.
Receiver 5 for holding cosmetics 13 by pressing down with 2
is arranged so that it can be raised and lowered, and this saucer 5 is pushed up against a spring 12 and pushed out to the outside by an elevating cylinder 3 that is raised and lowered by the relative rotation between the main cylinder 1 and the rotating cylinder 2. Feeding and loading the cosmetics 13 is basically the same operation as for general products and is simple, and when replacing the cosmetics, the auxiliary tube 4 can be removed from the rotary tube 2 with a screw and reinstalled, so it is easy and convenient.
No hassle. In addition, unlike conventional products, there is no need to provide a guide hole for the inner plate to split the inner tube 7 into two, and there is no need for strong force to be applied during replacement and installation, so the rotary tube 2, the inner tube 7, etc. are not deformed. There are no concerns at all.
