Description

[Detailed Description of the Invention] The present invention relates to an extrusion container for bar-shaped cosmetics, and its purpose is to enable smooth and stable extrusion operations.

The most common configuration of extruded containers for storing bar-shaped cosmetics such as lipsticks is an outer cylinder, an inner cylinder that is assembled into the outer cylinder so that they can rotate freely and cannot be removed, and a container that can be moved up and down into the inner cylinder. The main component is a saucer body on which a rod-shaped cosmetic product is placed, which can be assembled in a movable manner.

That is, a shaft piece is positioned protruding from the outside of the saucer body, and this shaft piece passes through a vertically elongated hole bored in the wall of the inner cylinder body, and its tip is engraved on the circumferential surface of the outer cylinder body. They are assembled by engaging with the threaded grooves, and the receiving tray body is moved up and down by rotating the outer cylinder body and the inner cylinder body relative to each other.

In this structure, since the shaft piece engages with the vertical hole and the threaded groove, the saucer body tends to wobble when the saucer body is raised and lowered, and the saucer body moves up and down with extremely weak rotational force. Since there is no resistance, the cosmetic product may protrude too much and cause it to break, or it may rotate naturally when not in use and damage the cosmetic tip.Furthermore, it may cause pressure on the cosmetic tip when in use. In addition, there was an inconvenience that the saucer body would descend.

The present invention relates to an extruded container for bar-shaped cosmetics devised to eliminate the above-mentioned conventional drawbacks and inconveniences, and the present invention relates to an extruded container for cosmetics in the form of a bar, which is provided on one side of a bullet plate that is integrally connected to the lower end of the cylinder of the saucer body via a hinge piece. It has a structure in which a protruding shaft piece is inserted from the inside into a hole opened in the cylindrical part.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes an inner cylindrical body, which has a configuration in which a short cylindrical rotating grip portion 3 having a slightly larger outer diameter than the cylindrical wall 2 is connected to the lower end of a straight cylindrical cylindrical wall 2. A stepped portion 4 is formed on the outer periphery of the continuous portion between the cylinder wall 2 and the rotating gripping part 3, and a pair of vertically elongated holes 5 are bored in the cylinder wall 2 facing each other from the upper end to the lower end.
Further, a locking strip 6 is provided around the outer periphery of the upper end of the cylinder wall 2.

The outer cylindrical body 7 is a straight cylindrical body having almost the same length as the cylindrical wall 2, and has an inner diameter equal to the outer diameter of the cylindrical wall 2. Spiral grooves 9 are formed facing each other.

Therefore, the outer cylindrical body 7 is assembled to the inner cylindrical body 1 with its lower end mounted on the stepped portion 4 of the inner cylindrical body 1 and its upper end engaged with the lower surface of the locking strip 6. and the outer cylindrical body 7 are assembled so that they can rotate freely and cannot be removed.

Next, the saucer body 10 is a cylindrical body having an outer diameter approximately equal to the inner diameter of the inner cylinder body 1, and has a bottom plate 11 in the center.
The lower part of the bar-shaped cosmetic is placed and stored in the upper part.

A through hole 13 is opened in the lower part of the cylindrical portion 12 which is lower than the bottom plate 11.
A hinge piece 14 is provided at the lower end of the cylindrical portion 12 facing the
A bullet plate 15 of a predetermined length is integrally connected through the bullet plate 15, and a shaft piece 16 is protruded from one side of the bullet plate 15.

Then, this bullet plate 15 is bent inward at the hinge piece 14, reversely curved, and fitted into the lower part of the cylindrical part 12.The shaft piece 16 is inserted into the through hole 13 from the inside, and the shaft piece 16 is inserted into the cylindrical part. It is made to protrude outward from 12.

In other words, the bullet plate 15 is curved within the cylindrical portion 12 so that one surface on which the shaft piece 16 protrudes is located near the cylindrical portion 12 where the through hole 13 is formed.
Therefore, the shaft piece 16 inserted into the through hole 13 projects outward from the cylindrical part 12 and is always urged outward, so that the bullet plate 15
The length of the shaft piece 16 is set so that the shaft piece 16 can be inserted into the through hole 13 and sufficient elasticity can be obtained by curving the shaft piece 16 so that the above-mentioned urging force can be applied.

A shaft piece 17 is integrally provided on the outer surface of the portion of the cylindrical portion 12 facing the through hole 13, and a plurality of slits are cut out in the lower portion of the cylindrical portion 13, so that the through hole 1
3 and the shaft piece 17 are provided with a tongue piece 18 that can be deformed outwardly.

The saucer body 10 having the above-described configuration is assembled into the inner cylinder body 1. That is, the shaft pieces 16 and 17 protruding from the through hole 13 are passed through the longitudinal hole 5 of the inner cylinder 1 and engaged in the threaded grooves 9 of the outer cylinder 7 to be assembled, respectively. The tip is pressed against the bottom surface of the threaded groove 9 under the force of the bullet plate 15, causing the outer cylindrical body 7 and the inner cylindrical body 1 to mutually rotate to rotate the shaft pieces 16, 17. When the tray body 10 is moved up and down by being guided by the elongated hole 5 and the threaded groove 9, it is subjected to a moderate amount of frictional resistance.

In addition, the bullet plate 15 with the shaft piece 16 protruding from the receiving plate body 1
Since it is integrally connected to a part of the tray body 10, it is easy to curve and fit it into the lower part of the tray body 10, and since no separate member is required, assembly and molding are extremely easy.

As is clear from the above description, in the rod-shaped cosmetic extrusion container of the present invention, the shaft piece of the saucer body is always urged outward via the bullet plate, and the tip of the shaft piece is attached to the threaded groove of the outer cylinder body. Since it is pressed against the bottom of the groove, it is possible to avoid unforeseen situations such as the tray body shaking or naturally moving up and down due to vibration, etc., and protect the cosmetics. The present invention has many excellent effects, such as being easy to use, easy to assemble, and easy to mold.
