Description

[Detailed description of the invention] The present invention relates to an extruded container for bar-shaped cosmetics such as lipstick. This is what I did.

Bar-shaped cosmetics are made by injecting and filling liquefied cosmetic materials into a mold, which is then cooled and solidified.However, even though they are solidified, bar-shaped cosmetics are extremely soft.
Not only is the surface easily scratched, but its shape is also easily distorted by the action of a slight external force.

Therefore, the molding process and assembly into the extruded container require great care, but despite such careful work, the production speed is extremely low. There were disadvantages in that the process was slow and a large number of defective products were produced.

For this reason, conventionally, when molding this type of bar-shaped cosmetic product and assembling it into an extrusion container, a mold is assembled onto the tray of an already assembled extrusion container, and this mold and part of the tray are combined into a mold. As part of the process, a distantly related method was used in which a bar-shaped cosmetic product was molded and at the same time, the molded bar-shaped cosmetic product was attached to a saucer.

With this method, the bar-shaped cosmetic product is molded and at the same time, it is firmly attached to the tray, so there is no need to handle the molded bar-shaped cosmetic product as a single item. It has the advantage that there is no risk of inconveniences such as breakage.

However, during the molding operation and cooling solidification operation of bar-shaped cosmetics, not only the mold but also a large weight and volume extrusion container must be handled as one unit, which makes the handling more troublesome and makes the bar-shaped cosmetics difficult to handle. During cooling and solidification, the extrusion container must also be cooled and solidified, so the effect of cooling and solidifying bar-shaped cosmetics becomes extremely poor, and only limited cooling methods that do not adversely affect the extrusion container can be used. Ta.

In order to overcome the drawbacks of the conventional methods of molding bar-shaped cosmetics and assembling them into extrusion containers, we have provided a holder that can be easily fitted and assembled from above onto the tray of the extrusion container. By assembling the holder into a mold, molding a bar-shaped cosmetic only by the combination of the mold and the holder, firmly assembling the bar-shaped cosmetic to the holder, and assembling the holder to the saucer, A method has been devised in which a bar-shaped cosmetic product can be firmly attached to a receiving tray via this holder.

This method has the advantage that it is extremely easy to mold bar-shaped cosmetics because the combination of the mold and the holder can be handled separately from the extrusion container.

The present invention relates to an extrusion container for bar-shaped cosmetics that is designed to be used in the above-described method for molding and assembling bar-shaped cosmetics.Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the extruded container according to the present invention, an outer cylinder 4 having a threaded groove 5 carved on the inner peripheral surface is rotated around an inner cylinder 1 having a handle 3 formed at the lower end and a vertical hole 2 bored over almost its entire length. It is movably but not removably assembled on the exterior, and inside the inner cylinder 1,
A saucer body 6 is formed by passing a protrusion protruding from the outer peripheral surface of the cylindrical base body through the vertical hole 2 and fitting it into the screw groove 5.
The inner cylinder body 1 and the outer cylinder body 4 are assembled so that they can slide and move up and down by mutual rotation.

The above-mentioned structure is exactly the same as the structure of extrusion containers commonly used in the past, but in the case of the present invention, a locking step 8 is further formed at the lower end of the inner circumferential surface of the receiving tray body 6. In addition to the extruded container main body which is separated from the inner cylinder 1, the outer cylinder 4 and the saucer 6, there is also a cylinder part 10 that tightly fits into the open end of the mold 14 for molding the bar-shaped cosmetic product 15. An assembly cylinder 11 that fits snugly into the saucer body 6 is provided hanging from the lower end, and the locking step portion 8 is attached to the lower end of the outer peripheral surface of the assembly cylinder 11.
A locking piece 12 is provided protrudingly to lock the locking piece 12.
A holder 9 is provided with a groove 13 cut in the lower end of the assembled tube 11 which is protruded from the bottom end.

As is clear from FIG. 2, the holder 9 is used by being assembled to the saucer 6, and the cylindrical portion 10 is never larger in outer diameter than the cylindrical body that is the base of the saucer 6. The lower end surface of this cylindrical portion 10 comes into contact with the upper end surface of the saucer body 6.

That is, only when the holder 9 is assembled to the saucer body 6 in which the lower end surface of the cylindrical portion 10 comes into contact with the upper end surface of the saucer body 6, the locking piece 12 engages with the locking stepped portion 8 of the saucer body 6. It is designed to stop.

Further, the split groove 13 is formed to extend above the locking piece 12, and when the holder 9 is assembled to the saucer body 6, the lower end of the assembled cylinder 11 on which the locking piece 12 is formed. The portion is easily elastically deformed, so that the holding body 9 can be easily assembled to the receiving tray body 6.

In the case of the illustrated embodiment, an inwardly directed protrusion is provided in the continuous portion of the cylinder part 10 and the assembly cylinder 11, but this is not suitable for assembling the molded bar-shaped cosmetic 15 into the holder 9. This is to make the attachment stronger.

Since the present invention has the above-mentioned configuration, the formwork 14
The holder 9 is assembled into an inverted form, and the liquefied material is injected and filled into the inverted combination of the mold 14 and the holder 9, and this is cooled and solidified to form a bar-shaped cosmetic product 15. At the same time, the rod-shaped cosmetic product 15 is firmly attached to the holder 9.

The combination of the holding body 9, the mold 14, and the bar-shaped cosmetic 15 is handled as one unit without removing the mold 14, and the saucer body 6 is positioned at the upper limit position as shown in FIG. Attach the holder 9 to the tray body 6 along the arrows on the extrusion container body.

By assembling the holder 9 to the tray body 6, the bar-shaped cosmetic 15 is assembled to the tray body 6 via the holder 9.

By assembling the holder 9 to the tray body 6, the bar-shaped cosmetic 15 is assembled to the tray body 6 via the holder 9.

Once this assembly of the holder 9 to the tray body 6 has been achieved, the formwork 14 is assembled between the holder 9 and the bar-shaped cosmetic 1 by appropriate means.
When removing the formwork 14, which can be removed from the assembly with the formwork 5, it goes without saying that a mold release agent should be applied to the inner peripheral surface of the formwork 14 in advance. If the outer diameter of the lower end where the opening is set is larger than the inner diameter of the upper end of the inner cylinder 1, the mutual rotation of the inner cylinder 1 and the outer cylinder 4 will cause the saucer body 6 to
When the assembly of the holder 9 and the cosmetic bar 15 is lowered together, the lower end of the mold 14 butts against the upper end of the inner cylinder 1 and cannot be moved downward, thereby preventing the extrusion of the cosmetic bar 15. The mold 14 can be successfully removed from the assembly of the holder 9 and the bar-shaped cosmetic 15 by the operation of storing it in the container.

In addition, the assembly of the holding body 9 to the saucer body 6 is performed using the assembly cylinder 11.
It is only necessary to fit the holding body 9 into the saucer body 6, and the assembly of the holding body 9 and the saucer body 6 is strongly held by the locking between the locking step portion 8 and the locking piece 12. 12 makes a snapping sound when it is locked to the locking stepped portion 8, and this sound serves as a guide for the assembly work, so that efficient assembly work can be achieved.

As is clear from the above explanation, the present invention provides bar-shaped cosmetics 1
5 to the saucer body 6 can be achieved strongly and easily, and during assembly, the bar-shaped cosmetics 15 can be easily handled and there is no risk of damage. It has many excellent functions and effects, such as being able to be conveniently molded and assembled without considering attachment.
