Abstract

The utility model discloses an improved telescopic lipstick casing, which comprises a rotary body, a lipstick base and an outer cover. The telescopic lipstick casing is characterized in that the outer cover has an internal thread, the helix angle of which is smaller than 22 DEG, and a convex nail of the lipstick base goes through a passing through of the rotary body and is matched with the internal thread. Compared with the existing lipstick body of the same class, the utility model has the characteristic that a lipstick can be positioned at any position of a rising and falling area, and the utility model has the advantages of easy use and simple structure.

Description

Lipstick telescopic case

The utility model belongs to the housing of a kind of shell of cosmetics, particularly scalable lipstick.

The scalable lipstick of present common use, its structure comprise rotary body and are installed on the lipstick base in it and are placed in its outer overcoat three parts formation.Control lipstick base in a rotating body oscilaltion by rotating rotary body during use.Because the reasons in structure of this housing, lipstick has only two kinds of states in use: the one, be fully retracted in the shell, the one, and be raised to peak, if be in other position in lifting zone, lipstick one stressed will down contracting automatically, this has brought inconvenience to use, and the while lipstick is in the extreme higher position and wrecks easily.

The purpose of this utility model provides a kind of housing of improved scalable lipstick, and its lipstick all can be located in any position in lifting zone, can overcome the shortcoming of prior art, and structure is simpler.

The utility model is achieved in that a kind of housing of scalable lipstick; Comprise rotary body and be installed on the lipstick base in it and be placed in its outer overcoat, it is characterized in that this is with a helical angle smaller or equal to 22 ° internal thread outward, and lipstick base passes thorough cut and described screw-internal thread fit on the rotary body by its protruding nail in outside.

The overcoat of such scheme adopts the internal thread smaller or equal to 22 ° of helical angles, and the thorough cut that the protruding nail of lipstick base passes rotary body is mated, frictional force in the time of can making protruding nail be subjected to responsive to axial force like this is greater than its sliding force, so lipstick can be located automatically in any position in lifting zone, thereby reach purpose easy to use, that the lipstick rate that wrecks greatly reduces, simultaneously because thorough cut two ends of rotary body need not to set bit architecture, so structure is also comparatively simple.

Below in conjunction with accompanying drawing the utility model is done to describe more specifically.

Fig. 1 is the vertical profile schematic diagram of a kind of scheme of the utility model, and Fig. 2 is that the overcoat of Fig. 1 separates stereogram, and Fig. 3 is the sectional side elevation of overcoat.

With reference to Fig. 1～Fig. 3, the housing of this scalable lipstick, comprise rotary body 1 and be installed on its interior lipstick base 2 and the overcoat 3 that is placed in outside it, feature is the internal thread 4 that this overcoat 3 has pitch angle alpha will≤22 °, and lipstick base 2 is cooperated with described internal thread 4 by the

thorough cut

7 and 8 that the protruding

nail

5 and 6 in the outside passes rotary body 1 respectively.During use, laying lipstick in the lipstick base 2, when rotating the bottom of rotary body 1, the protruding

nail

5 and 6 that is limited in

thorough cut

7 and 8 will rise or descend along internal thread 4, thereby realizes the flexible of lipstick.In this case, except that rotating rotary body 1, lipstick can not be subjected to axial force and under contract.

Claims

A kind of housing of scalable lipstick, comprise rotary body and be installed on its interior lipstick base and the overcoat that is placed in outside it, it is characterized in that this outer is with a helical angle smaller or equal to 22 ° internal thread, and lipstick base passes thorough cut and described screw-internal thread fit on the rotary body by its protruding nail in outside.
