Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a liquid cosmetic container suitable for using a liquid cosmetic such as mascara, eyeliner, and nail enamel.

(Prior Art) Conventionally, a coating shaft having a coating portion is attached to a cap, the coating shaft is inserted into a container main body, liquid coating material is contained in the coating portion, and the coating shaft is pulled out together with the cap and held in the coating portion. A liquid cosmetic container capable of applying the above-mentioned cosmetic to a required site is known.

The cap of such a known liquid cosmetics container is generally attached to the container body by means such as screwing or fitting, but in any case, in order to change the cap from the closed state to the open state, the container body and the cap are There is a relative desorption distance between and, and it is necessary to move the cap a certain distance outward relative to the container body.
Therefore, when the cap is formed so that the tip of the coating shaft reaches the bottom of the container when the cap is removed from the container body, it becomes impossible to close the cap. This means that the dimension of the coating shaft must be shortened by the attachment / detachment distance of the cap. As a result, when the cap is taken out from the container body and used, as shown in FIG. There is a drawback in that the tip of the shaft cannot reach the bottom of the container body, and a considerable amount of liquid cosmetic remains in the container in an unusable state.

(Problems to be Solved by the Invention) This invention makes it possible to advance or retract the coating shaft by advancing or retracting the coating shaft by rotating the cap when the cap is mounted or removed, thereby enabling the coating shaft to move forward or backward. In some cases, the coating shaft is moved back and forth so that the coating shaft does not interfere with the mounting of the cap.
The purpose is to reduce the residual amount of cosmetics as much as possible and prevent damage to the threads.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by the present invention are
At the mouth of the container (1), a cap (2) equipped with a coating shaft (3) having a coating part (4) at its tip is detachably mounted,

A spiral groove (5) is formed on the inner peripheral surface of the, and a projection (6) that engages with the spiral groove (5) is provided at the base of the coating shaft (3). In the illustrated embodiment, the spiral groove (5) is formed on the inner peripheral surface of the screw cylinder (7) which is separate from the cap (2), and the screw cylinder (7) is inserted into the cap (2). Insert it again
The protrusion (6) projects outward from the inside of the ring (8) fixed to the base of the coating shaft (3) by the elastic force of the spring (9), and can elastically move in and out of the spiral groove (5). It is composed of a pin that engages with, but is not limited to this.
For example, the spiral groove (5) may be directly formed on the inner surface of the cap (2), or the protrusion (6) may be directly integrated and projected on the outer peripheral surface of the ring (8) as shown in FIG. In addition, any structure or means for providing other spiral operation may be used.

However, as shown in FIG. 3, when the protrusions (6) are elastically engaged with each other by the spring (9), the protrusions (6) at the end of the spiral groove (5) do not resist the spring (9). Then, it becomes a retracted state, the overrun of the projection can be prevented, and the damage of the screw thread can be prevented.

A rotation stopping part (10) that allows the axial movement of the coating shaft (3) while engaging with each other inside the container body (1) and the coating shaft (3) to prevent relative rotation. (11) is provided, and when the cap (2) is rotated for loading and unloading from the container body (1), the cap (2) and the coating shaft (3) are screwed onto the coating shaft (3). Rotational force is applied, but since the rotation of the coating shaft (3) is blocked by the engagement of the rotation stoppers (10) and (11), only forward or backward movement in the axial direction is allowed.

Rotation stoppers (1) provided on the container body (1) and the coating shaft (3)
0) (11) is a corresponding non-circular cross section, for example a square cross section,
It is formed to have an elliptical cross section or the like, or a structure such as a key and a key groove, and engages both rotation stop parts (10) (11) in a state in which relative rotation is impossible.

With reference to FIGS. 2 to 4, the coating shaft (3) is formed in a prismatic portion having a diameter slightly larger than its lower portion from its base portion to a middle portion, and a lower portion of the prismatic portion is a cylindrical body having a diameter slightly smaller than this. It is formed, and the prismatic portion constitutes the rotation stopping portion (10). Detent (10)
The shape is not limited to this, and the whole may be formed in a prismatic shape. Further, the prismatic portion is not limited to the hexagonal cross-section shown in the drawing, and various other shapes such as a rectangular cross-section or an ellipse can be selected. Then, the inner peripheral surface of the mouth of the container body (1) is formed into a square cylindrical rotation stopping portion (11) corresponding to the prismatic rotation stopping portion (10) of the coating shaft (3).

The cap (2) and the container body (1) are screw means (12).
The application shaft (3) and the cap (2) are screwed together by the screw means (12) so that the application shaft (3) relatively advances when the cap is removed corresponding to the removal and attachment of the cap (2) by the screw means (12). ) And form a screw means. Therefore, when the cap (2) is unscrewed from the container body (1),
As shown in the figure, since the coating shaft (3) is in the non-rotating state due to the engagement with the rotation stoppers (10) (11), the relative screw movement between the spiral groove (5) and the protrusion (6) , The relative action of the rotation of the cap and the rotation stop of the mouth portion causes the advance of the coating shaft (3), and the dimension of the coating shaft (3) is substantially expanded.
Thus, as shown in FIG. 14A, with the cap (2) removed, the application part (4) can reach the bottom of the container body (1), and the cosmetic on the bottom of the container can be applied (4). It is possible to reduce the residual amount of unusable cosmetics because it can be used by adhering to ().

On the contrary, when the cap (2) is attached, the cap is rotated in the opposite direction to the above, so that the coating shaft (3) is relatively moved by the relative screw movement between the spiral groove (5) and the protrusion (6). 13A, the dimension is shortened substantially as shown in FIG. 13A. Therefore, the coating shaft (3) is inserted into the container body (1) without any trouble, and the cap (2) is attached. It can be closed.
