Description

[Detailed Description of the Invention] The present invention relates to an extrusion container for bar-shaped cosmetics, and its purpose is to prevent the bar-shaped cosmetics contained therein from being twisted or destroyed by the extrusion operation.

The container is used as a molding space for bar-shaped cosmetics, and the molten bar-shaped cosmetic material is injected and filled into the space formed by the storage cylinder and the saucer of this extrusion container as a molding space, and then cooled and solidified. There are extruded containers that can simultaneously form and store bar-shaped cosmetics by
This type of extrusion container must be moved up and down without rotationally displacing the tray with respect to the storage cylinder of the container to prevent the bar-shaped cosmetics from twisting or collapsing during the extrusion operation, so the tray must be pressed directly with the fingertips. It was structured in such a way that it was raised upwards.

That is, like a general bar-shaped cosmetic container, the storage cylinder part and the saucer part are screwed together so that they can rotate relative to each other, and the saucer part is rotated relative to the storage cylinder part by rotating the saucer part with respect to the storage cylinder part. If the extrusion container has the function of moving up and down, the bar-shaped cosmetics molded using the storage tube as a mold must rotate relative to the storage tube during extrusion. Because it is in a state that is perfectly resistant to wear,
This is because if the cosmetic bar tries to rotate with respect to the cylindrical storage part together with the saucer, the shape of the soft cosmetic bar will be distorted due to the frictional force between the cosmetic cylindrical container and the cylindrical storage part.

In this way, extruded containers for bar-shaped cosmetics that are molded using a storage cylinder part and a saucer part as molds and stored at the same time have a structure in which the bar-shaped cosmetics are pushed out by pushing up the saucer directly with a fingertip. Since it is extremely inconvenient to use extruded containers with such a structure, it is preferable to use a container with a structure in which the saucer part is rotated with respect to the storage cylinder part and the saucer part is moved up and down with respect to the storage part using threaded engagement. It was desired to obtain convenience of use.

The present invention was devised in order to meet the above-mentioned needs of the conventional example, and includes a saucer mounted in the housing cylinder part of the outer cylinder so as to be movable up and down, and an upper end of the leg which is screwed and assembled to the outer cylinder. The legs are rotatably but non-removably assembled on a saucer, and a rotating means is provided for rotating the legs relative to the outer cylinder.Hereinafter, one embodiment of the present invention will be described. The explanation will be given according to the drawings shown.

In the figure, reference numeral 1 denotes an outer cylinder forming a storage cylinder part 10 that directly stores bar-shaped cosmetics (not shown). By providing a screw tube 12 on a concentric axis via a dividing plate 14 at a height position, the upper part of the interior becomes a storage cylinder part 10 and the lower part becomes a function cylinder part 11.
It is divided into

The spiral tube 12, which is arranged concentrically in the center of the cylindrical body that is the parent body by the dividing plate 14, has a short cylindrical shape,
A thread 13 is formed on its inner peripheral surface.

Inside the storage cylinder part 10 of the outer cylinder 1, a hanging cylinder 22 having a short cylindrical shape from the bottom surface of a saucer formed by a cylinder wall 20 and a bottom wall 21 and having a short cylindrical shape with a bottom is provided. A holder 2 having a ring-shaped flange 23 protrudingly provided on the lower end of the inner circumferential surface of the holder 2 is assembled so as to be movable up and down.

That is, the cylindrical wall 20 of the saucer has its outer peripheral surface connected to the storage cylindrical portion 1.
By almost exactly contacting the inner peripheral surface of 0,
A molding space for bar-shaped cosmetics is formed by the saucer and the storage cylinder part 10.

In the illustrated embodiment, the hanging cylinder 22 is formed by extending the cylinder wall 20 of the saucer downward as it is.

In addition, a thread 31 is provided on the outer peripheral surface of the outer cylinder 1 to engage with the thread 13 of the threaded cylinder 12. A leg 3 is rotatably attached to the upper end of the holder 2 and has a disk-shaped top plate 32 whose peripheral end is located between the receiving plate of the holder 2 and the flange 23.

That is, the top plate 32 has a diameter larger than the inner diameter of the hanging cylinder 22 and larger than the inner peripheral end diameter of the flange 23,
It has a flat disk shape with a thickness smaller than the distance between the lower surface of the bottom wall of the saucer and the upper surface of the flange 23, and its peripheral end is positioned opposite the upper surface of the flange 23 from above.

Therefore, even if the leg 3 rotates relative to the outer cylinder 1 and the leg 3 moves up and down with respect to the outer cylinder 1, the holding body 2 remains the same as the leg 3. Although it moves up and down, it does not rotate at the beginning.

Although the holding body 2 and the leg body 3 are assembled in such a way that they do not rotate idly, it is desirable that the frictional resistance between the holding body 2 and the leg body 3 is as small as possible. The most necessary force applied from the legs 3 to the holder 2 is the force that moves the holder 2 upward relative to the outer cylinder 1; The top plate 32 is designed to effectively apply push-up force with low frictional resistance.
As shown in FIG. 4, it is preferable to provide a circumferential protrusion 33 around the upper surface of the holder.

In this way, when the circumferential protrusion 33 is formed on the circumferential edge of the upper surface of the top plate 32, the leg body 3 is held only by the upper end edge of the circumferential protrusion 33 when transmitting the lifting force from the leg body 3 to the holding body 2. Since the body 2 is pressed against the body 2, the frictional connection area regarding the relative rotational movement between the holder 2 and the leg 3 is significantly reduced, and the rotation that is to be transmitted from the leg 3 to the holder 2 is reduced accordingly. The power will be small.

In this way, in order to move the holding body 2 up and down with respect to the outer cylinder 1 and make the bar-shaped cosmetics placed and held on the holding body 2 protrude from the inside of the storage cylinder part 10 of the outer cylinder 1, the outer cylinder Rotating means for rotating the legs 3 relative to the body 1 is required.

Various configurations are conceivable for this rotation means, but in the illustrated embodiment, it is constituted by a bottom cover body 4 that is rotatably but non-removably attached to the lower end of the outer cylinder body 1. ing.

That is, at the lower end of the outer cylinder 1, the engagement protrusion 42 is engaged with the engagement groove 15 provided around the lower end of the inner peripheral surface of the functional cylinder part 11, which is the lower part of the outer cylinder 1. Although the bottom cover body 4 is rotatable, it is assembled in such a way that it cannot be removed.

The bottom cover body 4 has an upright cylinder 41 in the shape of a short cylinder with an outer diameter equal to the inner diameter of the functional cylinder part 11 from the upper circumference of the bottom plate 40 in the shape of a flat disk that closes the lower end opening of the outer cylinder body 1. An engaging protrusion 42 that engages with the engaging groove 15 is provided around the upper end of the outer peripheral surface of the upright cylinder 41, and is screwed into the threaded cylinder 12 from the center of the upper surface of the bottom plate 40 to form a functional cylinder part. Leg 3 located within 11
A guide shaft 43 having a height approximately equal to that of the functional cylinder portion 11 fitted into the screw cylinder 30 is provided upright.

A desired number (see FIG. 3, four in the illustrated embodiment) of vertical strips 44 are provided on the outer circumferential surface of the guide shaft 43 fitted into the threaded tube 30.
is provided as a strip, which engages with a vertical groove 34 cut into the inner circumferential surface of the threaded tube 30, and the engagement between the vertical strip 44 and the vertical groove 34 causes the leg body 3 and the bottom cover body 4 to be connected to each other. are assembled so that they can be moved up and down relative to each other, but cannot be rotated.

That is, when the bottom cover body 4 is rotated with respect to the outer cylinder body 1,
This rotation of the bottom cover body 4 is directly transmitted to the leg body 3, and the leg body 3 moves up and down with respect to the outer cylinder body 1 due to this rotation, regardless of the position of the bottom cover body 4 with respect to the outer cylinder body 1. .

As described above, in the bar-shaped cosmetic extrusion container according to the present invention, the holder 2 and the legs 3 are assembled so that they can freely rotate relative to each other but move up and down together. When the bottom cover body 4 is rotated, the legs 3, which are assembled so as not to be idly rotated, become together with the bottom cover body 4 due to the engagement between the vertical strips 44 of the bottom cover body 4 and the vertical grooves 34 of the legs 3. As it rotates and is engaged with the screw tube 12, it moves up and down while rotating with respect to the outer cylinder body 1.

When the leg body 3 moves up and down while rotating with respect to the outer cylinder body 1, the holding body 2, which is assembled to the upper end of the leg body 3 and is fitted and assembled into the storage cylinder part 10, is connected to the leg body 3. Although the space between the parts can be freely rotated, it is assembled so that it cannot be moved up or down, so the outer cylinder body 1
The bar-shaped cosmetics stored in the storage cylinder part 10 is taken in and out from the storage cylinder part 10 by moving up and down together with the leg body 3 without rotating relative to the body.

At this time, since the holder 2 does not rotate relative to the outer cylinder 1, no rotational force, that is, twisting force, is applied to the bar-shaped cosmetic at all, and only a push-up or pull-down force is applied, so the storage tube There is no fear that the bar-shaped cosmetics stored in the part 10 in a state that is adhered to the inner circumferential surface of the storage cylinder part 10 will be torn or broken by the extrusion operation.

In addition, since the holding body 2 and the leg body 3 are completely separate objects,
The holder 2 may be molded with due consideration given to the fact that it serves as a mold for molding the bar-shaped cosmetic product, as an extrusion force acting part for the bar-shaped cosmetic product, and as a member that is perfectly assembled into the housing cylindrical portion 10. Since there is no need to consider the screwing function at all, there are many advantages in terms of the shape.

As is clear from the above description, the present invention has a structure in which the holding body 2 and the leg body 3 are completely separate bodies, and although both can freely rotate, they are assembled so that they can move up and down together. Stick-shaped cosmetics that easily lose their shape (ticks, lipsticks, etc.)
There is no fear that the holding body 2 will lose its shape or be twisted or crushed when it is put in and taken out from the inside of the storage cylinder 10, and without considering the operating function of the holder 2 with respect to the outer cylinder 1.
Since it can be molded into a convenient shape as a mold for bar-shaped cosmetics, it has many excellent functions and effects as an extrusion container for bar-shaped cosmetics, which is extremely advantageous for molding and storing bar-shaped cosmetics.
