Description

[Detailed Description of the Invention] The present invention relates to an extruded container for storing bar-shaped cosmetics such as lipsticks, and is aimed at achieving exposure and storage of bar-shaped cosmetics with an extremely simple structure.

A push-out container for bar-shaped cosmetics such as lipstick must completely contain and hold the stored bar-shaped cosmetics, and must expose the bar-shaped cosmetics in a usable state safely and without damage.

Conventionally, this type of extruded container had a structure in which the bar-shaped cosmetics were moved up and down relative to the cylinder housing the bar-shaped cosmetics to take them in and out. Since the cosmetic product itself has a structure in which it is moved up and down, the part that holds the bar-shaped cosmetic product tends to be loose when assembled with the container body, and this backlash causes the inconvenience that the bar-shaped cosmetic product is damaged.

Although various measures have been taken to prevent the occurrence of wobbling in the cosmetic holding portion, the structure of the extruded container has become complicated.

In addition, since conventional extruded containers extrude and displace cosmetics from within the container body to expose them, if an unauthorized rotational displacement occurs between the container body and the cosmetics, the stored cosmetics may be damaged. is pressed against the cap, causing damage. Because so-called "heading" occurs, it is necessary to provide a means to prevent this "heading".

The present invention was devised to fundamentally eliminate the drawbacks of the conventional examples described above, and instead of holding the bar-shaped cosmetic product immovably in the container body, a cylindrical body for storing the bar-shaped cosmetic product is attached to the container body. It is constructed so that it can move up and down.

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

The extruded container according to the present invention has an outer cylindrical body 1 and an inner cylindrical body 7.
and an intermediate cylinder 1 which is a movable part.
2 and a cap 16.

The outer cylindrical body 1 has a structure in which a locking step 4 is formed at the upper end of the inner peripheral surface of a cylindrical body 2 having a linear cylindrical shape, and provides the outer surface of the container.

In the illustrated embodiment, this outer cylinder 1 is a cylinder 2
A stepped portion 5 is formed at the upper end of the outer peripheral surface of the cylindrical body 2, and the upper end of the cylindrical body 2 is made into a fitting cylindrical piece 3 having a small outer diameter, and the cap 16 is configured to fit into this fitting cylindrical piece 3. There is.

The inner cylindrical body 7 has a cylindrical body 8 in the shape of a straight cylinder, which is disposed coaxially within the outer cylindrical body 1 and spaced apart from the outer cylindrical body 1. The upper end of the inner circumferential surface of the cylindrical body 8 is provided with vertical stripes and threaded grooves 11 for locking and holding the cosmetic bar, and the upper end of the cylindrical body 8 serves as a cosmetic bar holder 10. The inner cylindrical body 7 and the outer cylindrical body 1 are integrally joined at their lower ends by a bottom plate 6 to form a main body portion having a double cylindrical wall structure.

An intermediate cylinder 12 constituting a movable part of the main body consisting of the outer cylinder 1 and the inner cylinder 7 moves the cylinder wall into the space between the outer cylinder 1 and the inner cylinder 7. A threaded piece 15 that is threaded into the threaded groove 9 is provided protrudingly on the lower end of the inner circumferential surface of a straight cylindrical cylindrical body 13 that is assembled coaxially with the outer cylindrical body 1 and the inner cylindrical body 7, and the cylindrical body A locking protrusion 14 is provided on the lower end of the outer peripheral surface of the body 13 to lock the locking step 4 from below, and when the body 13 is at the upper limit with respect to the main body, When the locking protrusion 14 is locked to the locking step portion 4, the upper end can be positioned slightly above the upper end of the unused bar-shaped cosmetic held by the holding portion 10. It has a height.

The cap 16, which has a capped cylindrical shape, is detachably assembled by fitting its open lower end into the upper end of the outer cylinder 1. Needless to say, the height is such that the unconsumed bar-shaped cosmetic held in the holding part 10 does not collide with the holding part 10 when the holding part 10 is held.

In the case of the illustrated embodiment, a stepped portion 5 having a width approximately equal to the wall thickness of the cylindrical wall of the cap 16 is formed at the upper end of the outer peripheral surface of the outer cylindrical body 1. Since the cylindrical piece 3 is formed, the cap 16 holds the fitting cylindrical piece 3 until its lower end comes into contact with the stepped part 5.
As a result, the appearance of the container with the cap 16 attached is extremely simple.

Since the present invention is structured as described above,
From the illustrated state, the cap 16 is removed from the outer cylinder 1, the intermediate cylinder 12 is rotated in a predetermined direction with respect to the outer cylinder 1, and the intermediate cylinder 12 is moved downward, thereby holding the inner cylinder 7. The stick-shaped cosmetic held at 10 is exposed and used.

After use, the intermediate tube 12 is rotated relative to the outer tube 1 in the opposite direction to the above and displaced upward, the cosmetic is positioned within the intermediate tube 12, and the cap 16 is assembled to the outer tube 1. To achieve storage and retention of bar-shaped cosmetics.

In this way, when using and storing the bar-shaped cosmetic, the bar-shaped cosmetic does not move up and down relative to the main body at all, and only the intermediate tube 12 moves up and down, so that the bar-shaped cosmetic does not wobble with respect to the main body. There is no inconvenience such as wobbling of the assembled posture during the lifting/lowering displacement operation, and therefore no special structure is required for stabilizing the assembled posture of the bar-shaped cosmetic with respect to the main body part.

Furthermore, since the mutual positional relationship between the cap 16 assembled to the outer cylinder 1 and the bar-shaped cosmetic product is always constant regardless of the vertical position of the intermediate cylinder 12, accidents of "top-hitting" of the bar-shaped cosmetic product may occur. There is no need to worry about this, so you can use it with peace of mind.

Further, an outer cylinder 1, an inner cylinder 7 and an intermediate cylinder 12
Because it is a complete cylinder with no grooves, etc., and is assembled concentrically, it can exhibit high mechanical strength as a container and can be assembled with high precision, which allows for smooth assembly. It is possible to obtain suitable operation.

Furthermore, a main body portion consisting of an outer cylinder body 1 and an inner cylinder body 7 that can be considered as one body, and an intermediate cylinder 12.
Since its main parts are made up of , the structure is extremely simple and the assembly operation is also extremely simple.

As is clear from the above description, the extruded container according to the present invention has an extremely simple structure, allows for the insertion and removal of bar-shaped cosmetics extremely smoothly and safely, and has high strength as a container. It has many excellent functions and effects.
