Description

[Detailed description of the invention] The present invention relates to a dispensing container for stick-shaped cosmetics such as lipstick, foundation, and blush. Another object of the present invention is to provide a container for dispensing a cosmetic bar that prevents the cosmetic bar from breaking or falling out.

Conventionally, the filling and forming methods for bar-shaped cosmetics are as follows:
There are various methods, but in recent years, the method has been to set a mold in the middle tube, fill it with molten cosmetics, mold it, hold it in the middle tube, and fit the middle tube with a receiving tube having a protrusion. A method of obtaining a stick-shaped cosmetic dispensing container using this fact has been implemented. however,
The method of fitting the middle cylinder and the receiver is, for example, by forming a locking groove in the middle cylinder and forming a locking protrusion in the receiver, or by forming a locking protrusion on the outer wall of the middle cylinder. A common method for fitting the grooves is to form a plurality of vertical ribs on the inner wall of the receiving cylinder so that the grooves fit into each other in a so-called vertical rib format.

However, in the conventional method, when the inner tube and the receiving tube are fitted together, the inner tube is bent inward due to the stress of the fitting, which often results in deformation or breakage of the bar-shaped cosmetic material. Furthermore, when attempting to weaken the fitting stress to prevent deformation or breakage of the rod-shaped cosmetic, problems such as falling out may occur due to insufficient fitting between the inner tube and the receiving tube. Even in the case of the vertical rib type, it is extremely difficult to set the fitting stress appropriately from a design standpoint.

The present invention is an extremely useful bar-shaped cosmetic dispensing container that eliminates the above-mentioned drawbacks and also simplifies the setting process.

Hereinafter, embodiments of the present invention will be described based on the drawings. In FIG. 1, reference numeral 1 denotes an inner cylindrical body, which has a vertical hole 2 at a position facing the peripheral wall, and a base 3 for rotational operation having a somewhat larger outer diameter is connected to the lower part. Reference numeral 4 denotes an outer cylinder body which is rotatably fitted into the inner cylinder body 1, and has a spiral groove 5 formed therein. Reference numeral 6 denotes a receiving cylinder, which has a protrusion 7 that engages into a spiral groove 5 formed in the outer cylinder 4 through a vertical hole 2 formed in the inner cylinder 1. That is, by rotating the base 3 with respect to the outer cylinder body 4, the receiver cylinder 6 is configured to move up and down. Furthermore, as shown in FIG. 2, this receiving cylinder 6 has a locking pawl 8 on the inner circumferential wall and notches 9 at both ends of the locking pawl 8. In the embodiment shown in FIG. 2, two locking claws 8 are provided, but the receiving tube 6
The number may be set as appropriate depending on the material, shape, etc. Further, the shape of the notches 9 formed at both ends of the locking pawl 8 may be any shape as long as it imparts elasticity to the locking pawl 8. Furthermore, if the receiving tube 6 is made into a bottomed shape,
This is convenient since the bar-shaped cosmetic does not fall into the container.
10 is a middle cylinder, and as shown in FIG.
1 and a locking stepped portion 12, which are configured to lock with a locking pawl 8 formed on the receiving cylinder 6. As for the shape of the middle tube 10, it is convenient if the upper outer diameter is the same as the outer diameter of the receiver tube 6, since it becomes integral with the receiver tube 6 when fitted. 13 is a stick-shaped cosmetic such as lipstick, foundation, cheek blush, etc. held firmly in the inner tube 10, and 14 is a cap.

Next, a method for filling and forming a bar-shaped cosmetic and a method for setting it into a dispensing container will be explained together with its functions and effects.

First, as shown in FIG.
When the inner tube 10 is inserted into the inner tube 10, turned upside down, and filled with molten cosmetics such as lipstick, foundation, cheek blush, etc. from the bottom of the inner tube 10 and cooled and solidified, the inner tube 10 holding the bar-shaped cosmetic 13 is formed. can get. Next, the receiving tube 6 set in advance at the upper end of the feeding container
, the inner tube 10 holding the rod-shaped cosmetic 13 is placed in the mold tube 1.
It is sufficient to insert it with 5 still fitted (Fig. 5). At this time, the locking pawl 8 formed on the receiving tube 6
Climb over the locking step 12 formed in the middle cylinder 10,
Although it is locked in the locking groove 11, since notches 9 are formed at both ends of the locking pawl 8, elasticity is imparted to the locking pawl 8, so that it can smoothly climb over the locking stepped portion 12. Thus, the receiving tube 6 and the middle tube 10 can be easily fitted together. That is, the locking pawl 8 of the receiving tube 6 only deforms outward, and the middle tube 10 does not deform at all. Therefore, since no external force is applied to the bar-shaped cosmetic material 13 firmly held in the inner tube 10, the bar-shaped cosmetic material 13 will not be deformed or broken. Next, grasp the outer cylinder 4 from the state shown in FIG.
When the receiving cylinder 6 is moved downward, the lower end 15a of the mold cylinder 15 comes into contact with the upper end 4a of the outer cylinder 4, the mold cylinder 15 is removed, and the bar-shaped cosmetic is fed out together with the inner cylinder 10 into the container. is stored in.

As described above, the present invention not only facilitates the setting of molded bar-shaped cosmetics into a dispensing container, but also
This is an extremely useful bar-shaped cosmetic dispensing container that prevents the bar-shaped cosmetic from breaking or falling out.
