For example, the two elements may be electrically connected, or may be connected through an intermediate member, directly or indirectly. The specific meaning of the above terms can be understood by those of ordinary skill in the art as appropriate. In the embodiment of the present invention, if the terms "first \ second \ third" are used, similar objects are only distinguished, and do not represent a specific ordering for the objects. It is to be understood that the terms first, second, and third, where permissible, are interchangeable in particular order or sequences.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention. Also, the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained without inventive effort by a person skilled in the art according to the embodiments, are within the scope of the present invention.

One embodiment of the present invention provides a package for a lipstick. As shown in FIGS. 1-3, the package includes a lipstick cup 11, a guide tube 12 and a housing tube 13. The guide tube 12 includes at least one through slot 121 in a sidewall of the guide tube 12. The lipstick cup 11 is placed in the guide tube 12 and includes at least one driving protrusion 111 protruding out of the outer wall of the guide tube 12 through the through groove 121 so that the lipstick cup 11 can move up and down along the guide tube 12. Specifically, the driving protrusions 111 are located on the outer side wall of the lipstick cup 11. The outer casing tube 13 is sleeved outside the guide tube 12, and includes an outer wall which is smooth and is exposed during use of the lipstick, and an inner wall which includes a transmission spiral groove 131 matching with the transmission convex point 111 of the lipstick cup 11, and the depth of the transmission spiral groove 131 is smaller than the thickness between the outer wall and the inner wall.

In use, by rotating the guide tube 12, the lipstick cup 11 moves up and down along the inner wall of the housing tube 13. Because the driving protrusions 111 of the lipstick cup 11 are engaged with the driving spiral grooves 131 of the inner wall of the case tube 13 and the driving protrusions 111 are restricted by the through grooves 121.

Since the outer wall of the case tube 13 is exposed during the use of the lipstick, it is required that the appearance is beautiful, for example, the surface is required to be smooth and complete, there is no groove, gap, etc. having a structure that is bad for beauty, and therefore, the depth of the transmission spiral groove 131 is smaller than the thickness between the outer wall and the inner wall, i.e., the transmission spiral groove is not penetrated.

In the prior art, in order to achieve the purpose that the outer wall is attractive, the inner wall is provided with a transmission spiral groove, and a shell pipe is divided into an outer pipe and a spiral pipe and is assembled after being processed respectively. The outer pipe is made of high-hardness materials such as hard plastics or metal, so that the outer pipe is glossy and more attractive, and the spiral pipe is made of soft-hardness plastics and is easy to process a transmission spiral groove. However, this structure requires one more part, which increases the number of steps for machining and assembling.

Therefore, in the embodiment of the present invention, in order to simplify the structure, reduce the parts, and improve the assembly efficiency, the outer shell tube 13 integrates the functions of the outer tube and the spiral tube in the prior art, i.e. one outer shell tube 13 has the feature of beautiful outer wall, and is also convenient for processing the transmission spiral groove on the inner wall, see fig. 4-6.

In this embodiment, the material of the casing tube 13 is aluminum alloy. The outer shell pipe 13 made of aluminum alloy can meet the requirements of attractive appearance and good hand feeling, and can also directly process the transmission spiral groove 131 on the inner wall without overlapping other materials. Moreover, because the aluminum alloy has high strength, the wall thickness of the manufactured shell tube is far smaller than the superposed wall thickness of the shell tube and the spiral tube in the prior art, so that the appearance, lightness and fashionability of the shell tube 13 can be further improved, and the method is a preferred mode. Specifically, the excircle, the inner bore and the transmission spiral groove of the outer shell pipe 13 are formed by one-step processing, the efficiency is high, the yield is high, and the surface of the outer shell pipe is not easy to damage due to clamping. The spiral transmission groove 131 may be a large-pitch transmission thread or a non-standard thread.

In this embodiment, as shown in fig. 7, the package further comprises a damping ring 14, wherein the damping ring 14 is located below the guide tube 12. Thus, it is preferable to facilitate the rotation of the guide tube 12.

In this embodiment, the guide tube 12 and the damping ring 14 are integrally formed. This is preferable because the structure can be further simplified, the number of parts can be reduced, and the assembly efficiency can be improved. Specifically, the guide tube 12 and the damping ring 14 may be integrally formed by injection molding.

Further, the damping ring 14 may also be a separate member and fixed to the lower end of the guide tube 12 in an interference fit or mortise and tenon structure.

In this embodiment, the outer wall of the damping ring 14 includes at least one friction protrusion 141, and the friction protrusion 141 is in interference fit with the lower end of the inner wall of the housing tube 13. Since the damping ring 14 is made of plastic, even if the friction protrusions 141 are interference-fitted with the inner wall of the housing, the rotation is not hindered. However, the rotary damping ring 14 has a certain rotary resistance, has a better hand feeling, is more comfortable for users, and is a preferable mode. Specifically, the outer wall of the damping ring 14 includes four friction protrusions 141, which are uniformly distributed on both sides of the damping ring 14, and two friction protrusions 141 are disposed on each side, so that the rotation resistance is more uniform.

In this embodiment, the outer wall of the damping ring 14 further includes a positioning rib 142 for positioning the axial position of the outer casing tube, the positioning rib 142 surrounds the outer wall of the damping ring 14 for a circle, and the inner wall of the outer casing tube 13 is provided with a groove complementary to the positioning rib 142. In this way, it is preferable to be able to quickly locate the axial position of the housing tube 13 when assembling the product. Specifically, to facilitate injection molding, the positioning rib 142 has a mold release gap 144 formed in the circumference thereof to facilitate mold release.

In this embodiment, the guide tube 12 includes two through slots 121, and the two through slots 121 are oppositely distributed in the circumferential direction of the guide tube 12. Thus, the lipstick cup 11 is more balanced in the up and down movement, which is the preferred way. Correspondingly, the lipstick cup 11 includes two transmission protrusions 111, which are also positioned in correspondence with the through slots 121.

Further, the guide tube 12 may also include more through slots 121, the through slots 121 are uniformly distributed in the circumferential direction of the guide tube 12, and correspondingly, the transmission protrusions 111 are correspondingly disposed.

In this embodiment, as shown in FIG. 8, the driving protrusions 111 of the lipstick cup 11 are cylindrical. Thus, the matching with the transmission spiral groove 131 is more convenient, and the processing of the transmission spiral groove 131 can be simplified, which is a preferable mode.

In this embodiment, as shown in fig. 7, the upper end of one of the two or more through grooves 121 extends to and through the top end of the guide tube 12, and a fitting notch 122 for facilitating the insertion of the lipstick cup 11 into the guide tube 12 is formed at the top end of the guide tube 12. Thus, it is preferable that the lipstick cup 11 be fitted into the guide tube 12.

Further, the upper ends of two or more through grooves 121 may extend to and through the top end of the guide tube 12, which is more convenient for assembly.

In this embodiment, at least two longitudinally extending retaining ribs 112 for retaining lipstick are further disposed on the inner wall of the lipstick cup 11, and the retaining ribs 112 are uniformly distributed on the inner wall of the lipstick cup 11 in the circumferential direction. Thus, the shape of the lipstick is more easily maintained, and the lipstick can also be guided in a certain direction when inserted into the lipstick cup, which is preferable. The lipstick package according to the present invention further comprises a cap (not shown) directly fitted over the outer portion of the case tube 13 and a base (not shown) receiving the damping ring 14, when the base is rotated, the damping ring 14 and the guide tube 12 are rotated therewith. The cap is used for covering and sealing the lipstick, and the base is used for wrapping the damping ring, so that a user can hold and rotate the lipstick more conveniently, which is a preferable mode.

In this embodiment, the lower end of the outer circle of the damping ring 14 is provided with a connecting portion 143 for connecting the base. For example, the outer circle of the connecting portion 143 may include a protrusion extending in the longitudinal direction, so that after the base is sleeved in the damping ring, the base is fixed to the damping ring in the circumferential direction by the protrusion, that is, the base is rotated to drive the damping ring to rotate. In this way, a more secure connection of the base and the damping ring 14 and a simpler construction are preferred.

Further, from the viewpoint of cost saving, the base may even be eliminated. In this case, the user can rotate and lift the lipstick cup by directly rotating the coupling portion 143 of the damping ring 14. In another embodiment, the outer periphery of the connecting portion 143 of the damping ring 14 may be provided with protrusions or knurls for facilitating gripping rotation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
