Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention stores makeup sticks such as lip balm in a pour-on type, and allows the inner tray tube supporting the makeup sticks to be raised and lowered by operating an elevating device. In a cosmetic stick container, a structure that prevents the cutting waste of the cosmetic stick generated when the inner plate tube is raised and lowered from staining the outer periphery of the container, and a structure that prevents the cosmetic stick from breaking when applying it to the lips with the cosmetic stick. This invention relates to the structure of an inner plate tube that has the effect of increasing force.

[Conventional technology]

Cosmetic sticks such as lip balm are currently molded by pouring molten raw material into a cylindrical container and cooling it to solidify. That is, as shown in FIG. 1, a flat cylindrical base 1 and a base cylinder 2 protruding from the center of the upper surface of the base 1 are provided.
and a connecting wing 3 which is enlarged and formed on the upper surface of the base cylinder 2.
and a threaded rod 4 protruding from the center of the upper surface of the connecting blade 3.
and an outer cylinder 5 having a length that is sufficient to accommodate the screw rod 4 and having the same diameter as the pedestal, and a center of the inner bottom of the outer cylinder 5,
A plurality of coupling pieces 7 are provided protruding from the bottom periphery toward the center so that a coupling hole 6 having the same diameter as the base cylinder 2 is formed.
and a vertical lifting strip 8 protruding from the inner peripheral surface of the outer cylinder 5.
, an inner plate cylinder 9 that can be housed without any gap in the outer cylinder 5 and can slide; a bottom face 10 formed at the middle part of the inner plate cylinder 9; and a screw rod 4 inserted into the center of the bottom face 10. It is made up of a screw hole 11 formed in a manner that is possible to do so, and a lifting groove 12 formed in the outer circumferential surface of the inner plate tube 9 so as to be able to fit into the lifting strip 8.

Since it is configured in this way, the connecting blade 3 is connected to the connecting hole 6.
The threaded rod 4 is positioned above the connecting piece 7 through the screw rod 4.
After inserting into the outer cylinder 5, the lifting groove 12 is inserted into the lifting strip 8.
If the inner tray tube 9 is housed in the outer tube 5 while the screw rod 4 is screwed into the screw groove 11, even if the melted cosmetic stick raw material is poured into the container, it will not leak from the bottom of the container. Since the outer cylinder 5 above the dish cylinder 9 can be filled with it, the decorative stick 13 can be formed by cooling and solidifying it.

Then, if the base 1, that is, the screw rod 4 is rotated while holding the outer cylinder 5, the inner plate cylinder 9, which is prevented from rotating because the elevating groove 12 is fitted with the elevating strip 8, will be moved.
Instead of rotating, it rises or falls, but at this time,
Since there are dimensional errors in the molding of both the screw rod 4 and the inner plate cylinder 9, their rotation and vertical movement are always accompanied by wobbling.

However, since the cosmetic stick 13 has the same diameter as the inner diameter of the outer cylinder 5, there is no particular problem when ascending, but when descending, the outer cylinder 5 is attached to the side periphery of the cosmetic stick 13. The upper edge of the blade will dig in and be cut as it descends. Since the fine cutting chips 14 are fine, they are melted by even slight heat such as the sliding heat of the cosmetic stick 13 or the body temperature of the fingers holding the outer cylinder. The dye melts due to the so-called dropical phenomenon, and eventually spreads thinly over the entire outer circumference from the upper edge of the outer cylinder 5, resulting in a situation that impairs the usability of the container. Also, since the cosmetic stick 13 such as lip balm is softer than lipstick, as shown in FIG.
When applying No. 3, it often breaks if strong pressure P is applied in the lateral direction.
The broken surface is broken as if rotating, and the broken surface is formed so as to cut the decorative stick 13 along the upper edge surface of the inner tray cylinder 9.

That is, this type of conventional cosmetic stick container has two drawbacks: the outer periphery of the outer cylinder 5 may become soiled during use, and the cosmetic stick 13 is easily broken.

[Summary of the idea]

The present invention relates to a cosmetic stick container structure in order to minimize the above-mentioned defects such as staining and breakage, and by increasing the inner diameter of the upper part of the outer cylinder 5, the side circumferential surface of the cosmetic stick 13 and the inner diameter of the outer cylinder 5 are made large. Cutting debris 1 is present between the inner peripheral surface of the outer cylinder 5.
4 is formed, and the upper edge surface of the inner plate tube 9 is inclined to increase the resistance against breakage of the decorative stick 13.

[Example of idea]

Below, the structure of the cosmetic stick container according to this invention will be explained with reference to the drawings. Part 1 is as shown in Fig. 2.
The inner diameter is expanded to an appropriate depth from the upper edge of the outer cylinder 5, and then the inner diameter is further reduced to an appropriate depth while forming a gentle slope, and the inner diameter is returned to the inner diameter before expansion. Enlarged inner peripheral surface and cosmetic stick 13
A gap 15 is formed between the intermediate side circumferential surfaces.

The second type is as shown in FIG. 4, in which the upper edge surface of the inner plate tube 9 is inclined at an appropriate angle.

[Effect of the invention] Since the outer cylinder 5 of the cosmetic stick container according to this invention is configured as described above, the head of the cosmetic stick 13 is enlarged, and the head cannot be raised or lowered. Since the distance is short and the cutting material is used first, even if cutting waste is generated, the amount is small and does not pose much of a problem. And the important cosmetic stick 13 below the enlarged head
Unlike the angular upper edge of the outer cylinder 5, even if the side circumference is shaken, it will be in contact with the lower part of the gently sloped surface, so it will be difficult to cut it, and even if cutting waste 14 is generated, the side circumference of the decorative rod 13 will be cut off. The cutting waste 14 is accommodated in the gap 15 formed between the upper enlarged inner circumferential surface of the outer cylinder 5 and the cutting waste 14 hardly spills out onto the outer circumference of the outer cylinder 5. Furthermore, the breakage phenomenon of the cosmetic stick 13 is caused by the adhesive force of the component molecules of the cosmetic stick 13, that is, the combined adhesive force between the upper and lower component molecular surfaces of the cosmetic stick 13 whose boundary is the upper edge surface of the inner tray tube 9. This occurs when the pressure force P becomes smaller than P, so in order to resist the pressing force P and make it difficult to break, it is necessary to In other words, it is sufficient to increase the overall adhesive force between the two, and for this purpose, it is sufficient to increase the area of the upper edge surface of the inner plate tube 9.

That is, in the case of the conventional inner plate cylinder 9 whose upper edge surface is horizontal, the diameter of the inner plate cylinder 9 is increased to increase the area of the upper edge surface, that is, the decorative stick 13 is made thicker to increase the resistance against breakage. However, this cannot be easily done due to financial considerations and aesthetic balance of the shape of the design.

However, in the present invention, since the upper edge surface of the inner tray tube 9 is formed obliquely, the diameter of the inner tray tube 9 remains the same as before, and the area of the upper edge surface of the inner tray tube 9, that is, the component molecule of the decorative stick 13 Since the surface area can be increased, the integrated adhesive strength of the surface increases, and the resistance to breakage becomes stronger.

Incidentally, if the angle of inclination of the upper edge surface of the inner tray tube 9 is too large, the force for holding the decorative stick 13 will become too weak, and there is a risk that the decorative stick 13 may fall out of the inner tray tube 9, so please take this into consideration. However, if the angle of inclination is set to 45 degrees,
Since the area of the upper edge surface is approximately 1.5 times that when it is horizontal, the resistance force against the same pressing force P is also strengthened approximately 1.5 times by simple calculation.
