It should be understood that the spatially relative terms are intended to encompass different orientations of the components in use or operation in addition to those shown in the figure. For example, if a component in the figure is inverted, it is described as a component “above other component or structure” or “on other component or structure”. Therefore, the component will be positioned as “below other component or structure” or “under other component or structure”. Therefore, the exemplary term “above” may include both orientations “above” and “below”. The component may also be positioned in other different ways (rotated by 90 degrees or in other orientations), but the relative description of the space should be explained accordingly.


As shown in FIGS. 1-52, a cosmetic material carrier includes tube body 110 and bottom plate 120 fixedly connected to the tube body 110. Lug 111 protruding outward along a radial direction is provided on a sidewall of the tube body 110. Tab 121 for fixing a cosmetic material is provided on the bottom plate 120. The carrier 100 is configured to carry a cosmetic material, and is particularly suitable for a pasty cosmetic material, such as a lipstick, a lippie, a lip gloss, a deodorant balm and a deodorant cream. In response to filling, the cosmetic material, namely a paste, is injected into the tube body 110. The bottom plate 120 is configured to support the cosmetic material. The tab 121 on the bottom plate 120 is configured to fix the paste, prevent separation of the paste from the carrier, and prevent the paste from shaking to affect a makeup effect in use. The lug 111 on the tube body 110 cooperates with a rotatable cylindrical portion to define a moving path of the carrier 100. The carrier 100 provided by the present invention is an integrated piece. The lug 111 and the tab 121 are provided on the carrier 100. Compared with a traditional two-piece movable cylindrical portion, the present invention simplifies a manufacturing process and a mounting process, and lowers a lower production cost of the carrier 100. The lug is provided on the tube body 110. The tab 121 is provided on the bottom plate 120. The tab and the lug can be machined into any shape. The present invention solves problems of limited shapes of the tab and the lug and difficult control on a coaxiality of the tube body due to a fact that both the tab and the lug are provided on the tube body in the traditional integrated movable cylindrical portion. The coaxiality refers to an axial deviation between centers of unit circles in a cylindrical piece.


The tube body 110 includes an upper open end and a lower open end. The tube body 110 is a cylindrical structure that is open up and down and is internally hollow. In response to the filling, the paste is injected into the tube body 110 through the upper open end. In an implementation, as shown in FIGS. 1-12, the bottom plate 120 is fixedly provided at the lower open end. That is, the carrier is a hollow cylindrical structure with a lower end provided with the bottom plate 120, and an upper end being an open end. In another implementation, the bottom plate 120 is fixedly provided in the tube body 110 between the upper open end and the lower open end. Not shown in the figures, both the upper end and the lower end of the carrier are open ends, the bottom plate 120 is provided at a middle of the tube body 110 along an axial direction, and the bottom plate 120 is close to the lower open end of the tube body 110.

The second end of the tab 121 extends toward the upper open end and/or the lower open end. The second end of the tab 121 extends toward the upper open end and/or the lower open end, which at least includes the following solutions: In a first solution, when the bottom plate 120 is sealed at the lower open end, the second end of the tab 121 extends toward the upper open end. In a second solution, when the bottom plate 120 is located at the middle of the tube body 110, the second end of the tab 121 extends toward the upper open end. In a third solution, when the bottom plate 120 is located at the middle of the tube body 110, the second end of the tab 121 extends toward the lower open end. In a fourth solution, when the bottom plate 120 is located at the middle of the tube body 110, the second end of a part of the tab 121 extends toward the upper open end, and the second end of a part of the tab 121 extends toward the lower open end.


As shown in FIG. 1, a first end of the tab 121 is narrower than a second end of the tab 121. That is, a junction between the tab 121 and the bottom plate 120 is narrower than the free end of the tab 121. Optionally, the tab 121 is of a trapezoid-like structure.


The tab 121 may be provided along the axial direction of the tube body 110, and may also be inclined. Optionally, as shown in FIGS. 7-9, the tab 121 is inclined relative to an axial center of the tube body 110. That is, an included angle between the tab 121 and the bottom plate 120 is not a right angle. Optionally, the included angle between the tab 121 and the bottom plate 120 is an acute angle.


As shown in FIG. 8, the second end of the tab 121 forms bending portion 122 toward the sidewall of the tube body 110 or toward the axial center of the tube body 110. The tab 121 is inclined on the bottom plate 120, the first end of the tab 121 is narrower than the second end of the tab, and the second end of the tab 121 is provided with the bending portion 122. This further improves a strength of the tab for fixing the paste.


In an implementation, the tab 121 is fixed on an inner surface of the bottom plate 120. The tab 121 protrudes from the inner surface of the bottom plate 120. In the embodiment, the lower end of the tube body 110 is sealed by the bottom plate 120. The bottom plate 120 includes an inner surface and an outer surface opposite to each other. The tab 121 protrudes from the inner surface of the bottom plate 120. The tab 121 serves as an additional component relative to the bottom plate 120, namely the bottom plate 120 is not damaged in formation of the tab 121. The paste is carried on the inner surface of the bottom plate 120. The tab 121 on the inner surface is inserted into the paste, thereby fixing the paste.


To simplify a machining process, the tab 121 is formed by deformation of the bottom plate 120. Optionally, the tab 121 is formed by bending after punching and cutting the bottom plate 120.

In the embodiment, as shown in FIG. 50, three pairs of axisymmetric tabs 121 are provided on the bottom plate 120.


As shown in FIGS. 53-55, a cartridge core assembly includes the carrier 100, rotatable cylindrical portion 200, and spiral portion 300. The spiral portion 300 is sleeved on the rotatable cylindrical portion 200. The rotatable cylindrical portion 200 is sleeved on the carrier 100. A screw thread is provided on an inner side of the spiral portion 300. Guide groove 201 is formed in the rotatable cylindrical portion 200 along an axial direction. The lug 111 passes through the guide groove 201 and cooperates with the screw thread. When rotating relative to the rotatable cylindrical portion 200, the spiral portion 300 can drive the carrier 100 to move along the axial direction, such that the cosmetic material extends out of the cartridge core assembly or retracts back to the cartridge core assembly. The cartridge core assembly uses the carrier 100 in Embodiment 1. The carrier 100 is configured to carry the cosmetic material. In view of environmental protection, the carrier 100, the rotatable cylindrical portion 20 and the spiral portion 300 are formed by punching and cutting a metal sheet material. The metal material includes copper, iron, aluminum, etc. Optionally, the carrier 100, the rotatable cylindrical portion 20 and the spiral portion 300 are formed by punching an aluminum sheet material.
