Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bar-shaped cosmetic container, and in particular, it includes a cylindrical container made of plastic and a rotary knob disposed below the container so as to be rotatable relative to the container. a screw shaft that is erected on the rotary knob and extends upward within the container; and a saucer that is rotatable relative to the container between the screw shaft and the container, and that the screw shaft is threadedly engaged with the container. The present invention relates to a rod-shaped cosmetic container consisting of.

[Prior art and its problems] In order to store bar-shaped cosmetics in the container described above, heated and melted cosmetics are poured into the cylindrical container, water is sprayed on the sides of the container, and the interior is cooled with water. solidifies cosmetics.

In this case, cooling water may enter the container from between the lower end of the container and the upper end of the rotary knob, but this entered water is not easily drained. For this reason, the accumulated water may deteriorate the quality of the cosmetic, or it may ooze out to the outside when the cosmetic is used, causing discomfort.

In this regard, conventional containers have not taken particular consideration to watertightness. For example, Jikko 57-
As shown in FIG. 4, the container disclosed in Japanese Patent No. 53259 has an annular protrusion 2 for airtightness that protrudes inward from the inner surface of the peripheral wall near the rear end of the container 10.
, and on the other hand, the container 10 provided on the rotary knob 20
A non-tapered airtight surface 4 that comes into close contact with the annular protrusion 2 is provided on the outer circumferential surface of the insertion portion 3. Since this container simply brings the annular protrusion 2 and the non-tapered airtight surface 4 into close contact with each other, when water is sprayed onto the container, the container 10
Water may enter from between the and rotary knob 20.

In view of the above, the present invention aims to provide a bar-shaped cosmetic container that does not allow water to enter the container even when water is sprayed onto the side surface of the container.

[Means for Solving the Problems] The bar-shaped cosmetic container according to the present invention has an annular slope that slopes downward toward the outside on the shoulder of the rotary knob, and a thin annular protrusion on the lower end of the container. Vertically installed,
The tip of this annular protrusion is brought into close contact with the slope of the rotary knob.

[Function] In the bar-shaped cosmetic container of the present invention, the tip of the annular protrusion hanging down from the lower end of the container is in close contact with the annular slope provided on the shoulder of the rotary knob. In this case, the tip of the annular protrusion tries to recover inward due to the elasticity of the thin plastic, but since the slope slopes upward toward the inside, the tip of the annular protrusion is so close to the slope that water is not allowed to enter between the slope and the slope.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3, and 1 is a rod-shaped cosmetic container according to the present invention.

Reference numeral 10 denotes a plastic body of the container 1, which has a cylindrical shape elongated in the vertical direction. This condition 1
The upper end of the outer wall of 0 is formed to have a smaller diameter by one step, and a bottomed cylindrical lid 12 is crowned at this smaller diameter portion. 14 is a longitudinally long protrusion;
They are diametrically opposed on the inner wall of 0. 1
Reference numeral 6 denotes an annular engagement protrusion, which is provided at the lower end of the container 10 so as to protrude inwardly and downwardly.

Reference numeral 20 denotes a cylindrical rotary knob having a slightly larger diameter than the container 10, and has a recess 21 in the center of the lower part.
In addition, a large number of anti-slip vertical grooves 22 are provided on the outer peripheral surface.

Reference numeral 24 is a cylindrical stepped portion having a diameter slightly larger than the inner diameter of the engaging protrusion 16, and is protruded from the center of the upper surface of the rotary knob 20. Reference numeral 26 denotes an annular engagement groove, which is bored in the lower circumferential surface of the stepped portion 24, and the width of the engagement groove 26 is approximately the same as the height of the engagement protrusion 16 of the container 10. . By doing so, the engagement protrusion 16 is fitted into the engagement groove 26 of the stepped portion 24, and the stepped portion 24 and the rotation knob 20 can rotate relative to the container 10.

30 is a screw shaft provided with a thread on the circumferential surface, and is erected at the center of the upper surface of the step portion 24,
Its tip extends upwardly within the container.

40 is a tray for the rod-shaped cosmetic 32, and the container 1
It is placed inside 0. The saucer 40 has a through hole in its center, and a threaded cylinder 42 is erected around the periphery of the through hole. This screw tube 42
A screw groove is bored in the inner peripheral surface of the screw shaft 30, and the screw thread of the screw shaft 30 is screwed into the screw groove. Reference numeral 44 is a concave groove vertically bored in the diameter direction on the outer peripheral surface of the saucer 40, and has a shape corresponding to the protrusion 14 of the container 10, and engages with the protrusion 14 for relative rotation. are doing. By doing this, when the container 10 is gripped and the rotary knob 20 is rotated, the screw shaft 30 rotates in the same direction as the rotary knob 20, but the saucer 40 screwed with this screw shaft 30 is Since it has a relative rotational capacity, it does not rotate and rises. When the saucer 40 rises, the bar-shaped cosmetic material 32 placed thereon also rises, and its tip is exposed above the container 10.

In addition, in the embodiment, the rotary knob 20
Although the stepped portion 24 is interposed between the screw shaft 30 and the screw shaft 30,
This stepped portion 24 may be omitted and the screw shaft 30 may be directly installed upright on the rotating knob 20. In that case, condition 1
An engagement groove 26 with which the engagement projection 16 of No. 0 engages is provided at the lower part of the screw shaft 30, or a convex portion and a recess that engage with each other are provided on the lower surface of the container 10 and the upper surface of the rotary knob 20, respectively. It is preferable that the rotary knob 20 is provided so as to be rotatable relative to the container 10.

28 is an annular slope provided on the shoulder of the rotary knob 20, and this slope 28 is inclined downward toward the outside, and the outer end of the slope 28 reaches the outer peripheral surface of the rotary knob 20. There is.

Reference numeral 18 is a thin annular protrusion, which is attached to the container 1.
The height of this annular protrusion 18 is greater than the gap h between the lower peripheral end of the container 10 and the slope 18 directly below the lower peripheral end of the container 10. big.

Since the container 1 of the present embodiment is configured as described above, the rotary knob 20 is pressed from below to the lower end of the container 10 so that the engaging protrusion 16 of the container 10 is inserted into the engaging groove 24 of the stepped portion 24. When inserted, the tip of the annular protrusion 16 abuts the slope 28 of the rotary knob 20 and bends outward. The tip of this annular protrusion 18 tries to restore itself inward due to the elasticity of the thin plastic, but because the slope 28 slopes upward toward the inside, it is unable to restore completely. , the tip of the annular protrusion comes into close contact with the slope 28 in such a manner that it rides on the slope 28.

[Effect of the invention] In the bar-shaped cosmetic container according to the invention, the tip of the annular protrusion hanging down at the lower end of the container tries to return inward and comes into close contact with the annular slope provided on the shoulder of the rotary knob. Therefore, even if water is sprayed onto the side of the container, cooling water will not enter the container from between the container and the rotating knob.
