Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing a stick-shaped cosmetic such as lipstick, and more specifically,
The present invention relates to a stick-shaped cosmetic container in which a cosmetic is directly filled in a sleeve.

[0002]

2. Description of the Related Art Conventionally, various types of containers have been proposed for accommodating a stick-shaped cosmetic such as lipstick. Of this,
The structure in which the feeding mechanism for sliding the stick-shaped cosmetic up and down is arranged in the lower part of the container has a drawback that the mechanism part is not arranged around the stick-shaped cosmetic, so that the total length becomes long, but the outer diameter of the container is made thin. I was able to do something. As a specific configuration, a sleeve is fixed to the upper portion of the feeding mechanism, and a holding cylinder that slides up and down by the feeding mechanism is provided inside the sleeve. Then, by relatively rotating the sleeve and the base of the feeding mechanism, the feeding mechanism is operated and the holding cylinder is slid up and down.

Further, since only the holding cylinder is installed inside the sleeve, a method has been taken in which the melted cosmetic is directly filled into the sleeve and solidified in the sleeve to form a stick-shaped cosmetic. As a result, the solidified stick-shaped cosmetic is
The lower end is held by the holding cylinder, and the upper and lower parts of the sleeve are projected and retracted by the raising and lowering movement of the holding cylinder, so that the process of mounting the stick-shaped cosmetic material on the container can be automated.

This sleeve was molded from aluminum or an aluminum alloy because of its easy decoration and good moldability. Then, the surface was improved by imparting luster to the surface by a polishing process and performing an anodized film treatment to form an anodized film layer.

[0005]

However, when the sleeve was directly filled with the cosmetic, the solidified stick-shaped cosmetic was in contact with the inner wall of the sleeve. If the holding cylinder and the stick-shaped cosmetic are moved up and down by operating the feeding mechanism in this state, the stick-shaped cosmetic moves up and down while being in contact with the inner wall of the sleeve, so that stress is applied to the stick-shaped cosmetic and the stick-shaped cosmetic is broken. There was a risk of it.

[0006]

[Means for Solving the Problems] A feeding mechanism A is arranged below a holding cylinder 3 for holding a stick-shaped cosmetic 2, and the holding cylinder 3 and a sleeve 1 in which the holding cylinder 3 is housed are independent of other portions. The sleeve 1 has a structure in which a melted cosmetic can be directly filled by providing a storage space for the stick-shaped cosmetic 2
The resin layer 22 is provided on at least the inner wall of the above to improve the slipperiness of the stick-shaped cosmetic material 2.

In this sleeve 1, a base material 20 is formed of aluminum or its alloy, and an anodized film layer 21 is formed on the surface by anodized film treatment. The surface of the anodized film layer 21 remains unsealed. Electrodeposition coating is applied to form a resin layer 22 on the surface of the sleeve 1.

[0008]

In order to store the stick-shaped cosmetic 2 in the stick-shaped cosmetic container of the present invention, the cosmetic is heated and melted, and the melted cosmetic is directly filled in the sleeve 1 and then cooled and solidified to form a stick-shaped cosmetic. Set to 2. At this time, since the cosmetic material has entered the holding cylinder 3 and solidified, the holding cylinder 3 holds the lower end of the stick-shaped cosmetic material 2. Here, the feeding mechanism A
When the holding cylinder 3 is moved back and forth by operating, the stick-shaped cosmetic material 2 also projects from the sleeve 1. At this time, the stick-shaped cosmetic material 2 advances and retreats while making sliding contact with the inner wall of the sleeve 1, but since the resin layer 22 is provided on the inner wall of the sleeve 1 to improve the slidability with respect to the stick-shaped cosmetic material 2, sliding resistance is generated. Without doing so, stress is not concentrated on the stick-shaped cosmetic material 2 to prevent the stick-shaped cosmetic material 2 from being damaged.

[0009]

EXAMPLES First, the sleeve 1 of the present invention can be implemented as long as it is arranged below the stick-shaped cosmetic material 2 in which the feeding mechanism A is housed. This will be described below.

The stick-shaped cosmetics 2 such as lipstick and eye shadow are
It is held by the holding cylinder 3. Below the holding cylinder 3,
The screw rod 4 is hanging down. On the outer wall of this screw rod 4,
A male screw 5 is screwed. Further, a pair of flat portions 6 are provided on the side wall of the screw rod 4, and the male screw 5 is divided into two. Further, the lower end of the screw rod 4 is provided with an abutting portion 7 which projects outward from the screw rod 4.

The screw rod 4 penetrates the guide cylinder 8. A through hole 9 through which the screw rod 4 penetrates is formed in the center of the guide cylinder 8. The through hole 9 corresponds to the cross section of the screw rod 4 provided with the flat surface portion 6, and guides the guide cylinder 8 and the screw rod 4 so as to be non-rotatable and vertically slidable.

The tip of the screw rod 4 is inserted into the female screw cylinder 10. Further, the guide cylinder 8 is rotatably connected to the female screw cylinder 10 so as not to fall off. This female screw cylinder 10
A female screw 11 that is screwed into the male screw 5 of the screw rod 4 is screwed on the inner wall of the upper part of the. Below the female screw 11, the inner diameter is enlarged to form a step portion 12 at the lower end of the female screw 11. As a result, when the guide cylinder 8 and the female screw cylinder 10 are rotated relative to each other, the screw rod 4 is screwed into the female screw cylinder 10 in a state in which the rotation is blocked by the guide cylinder 8, and therefore the screw rod 4 is held by the screwing action. The cylinder 3 moves forward and backward. Further, the abutting portion 7 of the screw rod 4 comes into contact with the step portion 12 in the female screw cylinder 10 to prevent the holding cylinder 3 from rising. Further, the lower portion of the female screw cylinder 10 has an enlarged outer diameter to form a base portion 13, and an upper portion of the base portion 13 forms a connecting portion 14. A groove 15 is formed around the outer wall of the connecting portion 14.

The connecting portion 14 of the holding cylinder 3, the screw rod 4, the guide cylinder 8 and the female screw cylinder 10 is housed inside the sleeve 1. Of these, the guide cylinder 8 is fixed to the inner wall of the sleeve 1, and the female screw cylinder 10 is rotatable by engaging an engaging rib 16 provided on the inner wall of the lower end of the sleeve 1 with a groove 15 of the connecting portion 14. It is permanently connected. As a result, the sleeve 1
When the female screw cylinder 10 is relatively rotated, the holding cylinder 3 moves forward and backward.

The lower portion of the sleeve 1 is inserted into the outer cylinder 17, and the base portion 13 of the female screw cylinder 10 is fixed to the outer cylinder 17. The cap 1 is attached to the upper outer wall of the outer cylinder 17.
A fitting portion 19 is provided so that 8 can be detachably fitted.

The present invention can be implemented if the feeding mechanism A for advancing and retracting the stick-shaped cosmetic material 2 is arranged below the stick-shaped cosmetic material 2. Further, the feeding mechanism A can also be used as a spiral feeding mechanism, a pushing mechanism, or a sliding mechanism as long as the bar-shaped cosmetic material 2 can be moved forward and backward.

Next, a general filling method of the stick-shaped cosmetic material 2 in the stick-shaped cosmetic material container according to the embodiment of the present invention will be described. The stick-shaped cosmetic container of the present invention constitutes a kind of room for storing the stick-shaped cosmetic 2 in the sleeve 1 above the holding cylinder 3. Therefore, fill this room with cosmetics that have been melted by overheating,
The stick-shaped cosmetic material 2 can be constituted by cooling and solidifying. Further, as shown in FIG. 3, a hole 23 penetrating the bottom surface of the holding cylinder 3, the screw rod 4, and the bottom surface of the outer cylinder 17 is bored, and the cosmetic is filled in the sleeve 1 through the hole 23 on the bottom surface of the outer cylinder 17. You can also In this case, the hole 23 on the bottom of the outer cylinder 17 exposed to the outside is the product name,
It can be hidden by attaching the label 24 that describes the price and the like.

Next, details of the sleeve 1 of the stick-shaped cosmetic container of the present invention will be described. The sleeve 1 is formed by pressing a base material 20 from an aluminum or aluminum alloy plate, and performs an anodizing film treatment through a polishing process and a degreasing process to impart gloss to the surface to form an anodized film layer 21 on the surface. ing. Then, after dyeing with a predetermined color, a transparent electrodeposition coating is performed through a washing process without performing the sealing treatment of the anodized film layer 21 to form the resin layer 22 on the outer surface and the inner surface of the sleeve 1. As a result, when the sleeve 1 is filled with the cosmetic material to form the stick-shaped cosmetic material 2, since the resin layer 22 is interposed between the stick-shaped cosmetic material 2 and the sleeve 1, when the stick-shaped cosmetic material 2 advances and retracts. The slidability of the stick-shaped cosmetic material 2 and the sleeve 1 is improved.

[0018]

As described above, according to the present invention, since the resin layer 22 having a good sliding property for the cosmetic is provided on the inner wall of the sleeve 1, the melted cosmetic is filled in the sleeve 1 and solidified. Even in the case of the stick-shaped cosmetic material 2 that has been made to act, the resistance between the stick-shaped cosmetic material 2 and the inner wall of the sleeve 1 that occurs when the stick-shaped cosmetic material 2 moves back and forth is reduced by the resin layer 22.
Can be relaxed, the stress applied to the stick-shaped cosmetic material 2 can be reduced, and an accident that damages the stick-shaped cosmetic material 2 can be prevented.

As described in the embodiment, the sleeve 1 is made of aluminum or its alloy as the base material 20, and the anodic oxide coating layer 21 is formed on the surface thereof. In the structure in which the resin layer 22 is provided on the surface by coating, the resin layer 22 is provided inside and outside the sleeve 1, and therefore, the effect of protecting the anodized film layer 21 is also achieved. Also,
Since the resin layer 22 is provided in a state where the anodized film layer 21 is not sealed, the adhesiveness of the resin layer 22 is improved and the resin layer 22 is prevented from peeling off.
