The inner cover (12) is sheathed in the lower part of the outer cover (11). A side wall of the inner cover (12) has a first sliding column (121) provided in the first sliding groove (111) in a sliding manner. An inner wall of the middle ring (13) is provided with a first spiral groove (131), and is sheathed on the lower part of the outer cover (11) in a rotating manner, so that the first sliding column (121) is provided in the first spiral groove (131) in a sliding manner. An upper edge of the bottom cover (14) is connected to a lower edge of the outer cover (11) in a fixed manner. The middle binding core (20) is stuck in an inner cavity formed by the bottom cover (14) and the inner cover (12). By rotating the middle ring (13), the middle binding core (20) is automatically ejected downwards, and can automatically return to the shell (10) by directly pressing the bottom after use, thereby breaking through the traditional method of use whereby a cover is pulled out, and increasing the overall simplicity and convenience.

Description

Cosmetic container opening and closing structure

Technical field

The utility model relates to a cosmetic container, in particular to an opening structure of a cosmetic container.

Background technique

Nowadays, the commonly used packaging containers are capable of extruding or pouring out the contents after the cover is unscrewed. This method is popular, not novel enough, and is not convenient enough to use. With the wide variety of packaging containers, consumers have also put forward novel requirements for the way they use them. The existing rotary cap packaging container can be used without unscrewing the lid, but all of the liquid is discharged from the top, and the liquid large piece remains on the top of the lid, which is liable to cause pollution. In another existing side liquid dispensing packaging container, the liquid outlet is exposed to the outside, so that the contents are easily contaminated by the outside.

For example, lipstick is a commonly used cosmetic, generally in the form of a paste. When the user wants to use lipstick, the lipstick is protruded by removing the upper cover and rotating the container body to raise the bead seat. The structure of the container of the type is simple, the style is old, the use is not convenient, the carrying is not convenient, and the whole is not simple and beautiful.

Wherein the middle beam core comprises a spiral sleeve, an inner sleeve and a bracket, the bracket is mounted in the inner sleeve, and the inner sleeve axial wall is open on the outer wall of the bracket a second guide bar is arranged to lift and match the second sliding slot, the spiral sleeve is sleeved on the outer wall of the inner sleeve, and the spiral sleeve is arranged to cooperate with the second guiding column and to make the bracket up and down Lifting the second spiral groove.

Further, the middle beam core further includes an inner bottom cover fixedly disposed at a lower end of the inner sleeve.

Further, the inner wall of the inner bottom cover is provided with a plurality of side edges that are engaged with the outer wall of the lower end of the inner sleeve.

Further, a weighting block is disposed in the inner bottom cover.

Further, the outer wall of the inner cover is provided with an arc-shaped protrusion that frictionally engages the inner wall of the outer cover.

The embodiment of the present invention has the following beneficial effects: the utility model provides a new opening and closing structure of the cosmetic device container, and the middle beam core is automatically ejected downward by rotating the middle ring during use, and It can be directly pressed back from the bottom to automatically return to the outer casing, breaking through the traditional way of using the cover, greatly increasing the simplicity and convenience in use, and bringing good fun.

detailed description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings.

Refer to the schematic diagram of the structure shown in FIG. 1.

A cosmetic container opening and closing structure according to an embodiment of the present invention includes a housing 10 and a center bundle core 20.

The housing 10 includes an outer cover 11, an inner cover 12, a middle ring 13, and a bottom cover 14. The first sliding slot 111 is disposed on the lower side wall of the outer cover 11 in the axial direction, in this embodiment. The first sliding slot 111 is preferably an open slot. Referring to the structural schematic diagram shown in FIG. 3, the inner cover 12 is disposed in the lower portion of the outer cover 11, and the side wall of the inner cover 12 is slidably disposed in the first sliding slot 111. The first sliding column 121 is provided with a first spiral groove 131 on the inner wall of the middle ring 13. The middle ring 13 is rotatably disposed on the lower portion of the outer cover 11, so that the first sliding column 121 is slidably disposed in the first spiral groove 131, and the bottom cover The upper edge of the cover 14 is fixedly connected to the lower edge of the outer cover 11. Under the rotation of the middle ring 13, the first spiral groove 131 drives the inner cover 12 to move up and down along the first sliding slot 111 of the bottom cover 14.
