The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

The following disclosure provides many different embodiments or examples for implementing the application. To simplify the disclosure of the present application, specific example components and methods are described below. Of course, they are merely examples and are not intended to limit the present application.

As shown in fig. 1 to 4, a cosmetic container 100 of an embodiment of the present application includes: flexible inner bottle 10, shoulder sleeve 50, bottle cap 20, bottle sleeve 30, and outer sleeve 40.

Referring to fig. 5, the flexible inner bottle 10 includes a bottle body 11 and a bottle mouth 12 at the top of the bottle body 11, and the sidewall of the bottle body 11 is provided with at least one protrusion 111 protruding outward. It will be readily appreciated that for the flexible inner bottle 10, which is made of a flexible material, the side walls of the bottle body 11 are pressed inwardly to deform when the boss 111 is pressed.

In some embodiments, the flexible inner bottle 10 may be made of soft glue, for example. In other embodiments, the flexible inner bottle 10 can be made of other flexible materials commonly used in the art.

Bottle cap 20 is used to open or close bottle opening 12. The flexible inner bottle 10 is formed with threads on the outside of the mouth 12, and the cap 20 is correspondingly threadedly coupled to the mouth 12.

The shoulder sleeve 50 is sleeved outside the bottle mouth 12 of the flexible inner bottle 10. The bottle sleeve 30 is sleeved outside the bottle body 11 of the flexible inner bottle 10, and the bottle sleeve 30 is connected with the shoulder sleeve 50. It will be readily appreciated that the vial socket 30, shoulder socket 50 and flexible inner vial 10 are assembled together by the connection of the vial socket 30 with the shoulder socket 50.

Referring to fig. 6, the sidewall of the bottle sleeve 30 is provided with at least one relief notch 311 for the passage of the at least one boss 111 of the flexible inner bottle 10. The relief notch 311 of the vial set 30 is disposed opposite the boss 111 of the flexible inner vial 10. Referring to fig. 8, each of the protrusions 111 is located in a corresponding one of the relief notches 311 and protrudes outward from a sidewall of the bottle sleeve 30.

The outer sleeve 40 is disposed outside the bottle sleeve 30. Referring to fig. 9 and 10, the side wall 42 of the outer sleeve 40 is oppositely provided with two slots 41 that are opened downward from the upper end of the outer sleeve 40, so that the side wall 42 of the outer sleeve 40 can be deformed when being pressed. The slots 41 and the protrusions 111 are circumferentially offset from each other so that when the side wall 42 of the outer sleeve 40 is deformed under pressure, the protrusions 111 of the flexible inner bottle 10 can be pressed inward to deform the side wall of the bottle body 11 by being pressed, thereby extruding the cosmetic from the flexible inner bottle 10.

It is easy to understand that the slots 41 and the protrusions 111 are circumferentially offset from each other, which means that the slots 41 and the protrusions 111 are not circumferentially coincident, i.e., the slots 41 and the protrusions 111 neither face each other, nor the slots 41 can be located directly above or below the protrusions 111. It will also be appreciated that in order to be able to press the projections 111 of the flexible inner bottle 10 inwardly when the side wall 42 of the outer sleeve 40 is deformed under pressure, the projections 111 should be covered by the side wall 42 of the outer sleeve 40.

In the embodiment of the present application, the side wall of the outer sleeve 40 is provided with the slot 41, so that the outer sleeve 40 has a deformation space; by providing the convex portion 111 in the flexible inner bottle 10 and providing the relief notch 311 in the bottle cover 30, the external sleeve 40 is pressed to transmit the acting force to the convex portion 111 of the flexible inner bottle 10, so that the cosmetics in the flexible inner bottle 10 can be squeezed out. Since only the protrusion 111 is actually applied to the pressing portion of the flexible inner bottle 10 when the outer sleeve 40 is pressed, the pressing area is reduced, and an excessive amount of liquid can be prevented from being discharged when the outer sleeve is pressed. In addition, this application embodiment extrudes cosmetics through pressing flexible interior bottle 10 indirectly, is similar to pressing the clip during the operation, can bring new experience for the user.

In some embodiments, the number of the protrusions 111 may be two, and two protrusions 111 are oppositely disposed on the sidewall of the bottle body 11. Accordingly, the number of yield slots 311 is also two; two relief notches 311 are provided on the side wall of the bottle sleeve 30 opposite each other.

In order to better transmit the forces to the lobes of the flexible inner bottle, each slot 41 may be located circumferentially in the middle of two lobes 111. In other words, the two slots 41 and the two protrusions 111 may be equally spaced in the circumferential direction.

The cross-section of the outer sleeve 40 may have an oval shape. The two slots 41 are located in the major axis direction of the ellipse, and the two protrusions 111 are located in the minor axis direction of the ellipse, thereby improving the comfort of the user's hand. In use, the two slots 41 may be located on the left and right sides to facilitate the pressing operation by the user.

In some embodiments, the slot width of the slot 41 is gradually reduced from top to bottom, thereby increasing the deformation of the sidewall 42 of the outer sleeve 40.
