[0036] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0037] It is also necessary to explain here that, in order to avoid obscuring the present application due to unnecessary details, only the device structure and / or processing steps closely related to the scheme according to the present application are shown in the accompanying drawings, while other details that are not very relevant to the present application are omitted.

[0038] The disclosure below provides a plurality of different embodiments or examples for implementing the present application. In order to simplify the disclosure of the present application, the components and methods of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the present application.

[0039] In the related art, when the packaging assembly mentioned in the background technology section is in use, the lower part of the tube, the lower part of the sleeve and the lower part of the cylinder are all located in the receiving groove of the base. In order to ensure that the tube can rotate relative to the base, there needs to be a gap between the tube, the sleeve and the receiving groove of the base. Since the outer diameter of the cylinder is usually larger than the outer diameters of the sleeve and the tube, in order to ensure that the lower part of the tube, the lower part of the sleeve and the lower part of the cylinder are all arranged in the receiving groove of the base, the radial dimension of the receiving groove is usually larger, which results in a larger gap between the receiving groove of the base and the tube.

[0040] In order to solve the above technical problems, an embodiment of the present application provides a packaging assembly.

[0041] Figure 1 is a schematic structural diagram of a packaging assembly according to an embodiment of the present application; Figure 2 yes Figure 1 Schematic diagram of the exploded packaging components shown. Figure 1 and Figure 2 As shown, the packaging assembly of the embodiment of the present application includes: a tube 11, a container 12, a cylinder 13 and an inner tube 14.

[0042] The pipe fitting 11 comprises an upper pipe section 111 and a lower pipe section 112 connected to the upper pipe section 111 . A guide groove 1121 extending in the axial direction is formed on the pipe wall of the lower pipe section 112 .

[0043] The container 12 is arranged radially inside the upper tube section 111, and defines a container groove with an opening on the top for accommodating rod-shaped materials. The cylinder 13 is sleeved radially outside the lower tube section 112, and the radial inner wall of the cylinder 13 is provided with a spiral guide groove 131 extending in an axial spiral direction.

[0044] The inner tube 14 is connected to the receiving member 12 . The inner tube 14 enters the lower tube section 112 from the bottom of the receiving member 12 downwards. The inner tube 14 forms a guide matching portion 141 that matches the spiral guide groove 131 .

[0045] See also Figure 3 The guide fitting portion 141 can pass through the guide groove 1121 and cooperate with the spiral guide groove 131, so that when the cylinder 13 rotates relative to the pipe 11, the accommodating member 12 can move axially in the pipe 11 through the cooperation between the guide fitting portion 141 and the spiral guide groove 131.

[0046] In the packaging assembly of the embodiment of the present application, the pipe 11 is configured to include an upper pipe section 111 and a lower pipe section 112, and the cylinder 13 having the spiral guide groove 131 is integrally arranged on the radial outer side of the lower pipe section 112, and the guide groove 1121 extending in the axial direction is arranged in the lower pipe section 112, so that the guide matching portion 141 of the inner pipe 14 can pass through the guide groove 1121 and match with the spiral guide groove 131, so that while ensuring that the container 12 can move in the axial direction of the pipe 11 in the pipe 11, the cylinder 13 can be moved in the axial direction of the pipe 11. Fig. 9 When the base 16 shown is assembled, since the cylinder 13 is arranged at the outermost side, the cylinder 13 is completely arranged in the receiving groove of the base. At this time, only the bottom end of the upper pipe section 111 of the pipe 11 is located in the receiving groove, which is beneficial to reduce the gap between the receiving groove of the base and the pipe 11.

[0047] In the embodiment of the present application, the tube 11 can rotate relative to the cylinder 13 to drive the container 12 to move in the axial direction of the tube 11, so that the container 12 can move in the axial direction from the first position where the rod-shaped material is inside the tube 11 to the second position where the rod-shaped material can be used. For example, when the tube 11 rotates relative to the cylinder 13 in a first direction, the container 12 can move from the first position to the second position in the tube 11; when the tube 11 rotates relative to the cylinder 13 in a second direction opposite to the first direction, the container 12 moves from the second position to the first position in the tube 11.

[0048] It is easy to understand that both axial ends of the pipe fitting 11 are open, that is, at both axial ends of the pipe fitting 11, except for the end faces of the pipe wall (the size of the end faces is consistent with the thickness of the pipe wall), no other end faces are provided. The pipe fitting 11 can be an integrally formed part.

[0049] The upper end of the cylinder 13 is open, and the lower end can form a lower end surface. In some embodiments, the lower end surface can be a closed surface. In some embodiments, the middle part of the lower end surface can form an opening, the size of which is smaller than the outer diameter of the inner tube 14, so as to form a limiting effect on the inner tube 14.

[0050] The lower end of the inner tube 14 may also be open. The outer diameter of the receiving member 12 is larger than the inner diameter of the lower tube section 112, and the outer diameter of the inner tube 14 is smaller than the inner diameter of the lower tube section 112 to prevent the receiving member 12 from entering the lower tube section 112. A plurality of spring pieces may be provided on the peripheral wall of the receiving member 12 to increase the connection strength with the rod-shaped material.

[0051] In some embodiments, the outer diameter of the lower tube section 112 is smaller than the outer diameter of the upper tube section 111, and the outer diameter of the cylinder 13 is the same as that of the upper tube section 111. In such an embodiment, since the outer diameter of the cylinder 13 is the same as that of the upper tube section 111, when the tube 11, the receiving member 12, the cylinder 13 and the inner tube 14 are assembled together, the upper and lower diameters of the entire assembly are consistent, which is conducive to further reducing the gap between the receiving groove of the base and the tube 11. In addition, the upper and lower diameters of the entire assembly are consistent, and when the base and the cover are manufactured, the size of the receiving groove of the base and the receiving groove of the cover can be the same, so that the receiving grooves of the base and the cover can be manufactured using the same mold, simplifying the manufacturing process and manufacturing cost.

[0052] See also Figure 4In some embodiments, the inner tube 14 is provided with openings 142 formed on the tube wall of the guide fitting portion 141 on both sides of the circumference; the two openings 142 are connected to the two circumferential ends of the guide fitting portion 141. The two circumferential sides here refer to the two sides of the guide fitting portion 141 along the circumferential direction of the inner tube 14. By providing the openings 142, the elasticity of the guide fitting portion 141 can be increased. On the one hand, it is convenient to insert the inner tube 14 into the lower tube section 112. On the other hand, it is also convenient to fine-tune the size of the guide fitting portion 141. When the size of the guide fitting portion 141 is slightly larger than the size of the spiral guide groove 131 due to processing errors, the size of the guide fitting portion 141 is slightly reduced by deformation so that it can enter the spiral guide groove 131.

[0053] In some embodiments, the number of the guide matching parts 141 is two, and the two guide matching parts 141 are arranged opposite to each other. In some embodiments, the guide matching parts 141 are arranged at the lower part of the inner tube 14 .

[0054] The edge of the tube wall of the inner tube 14 below a guide fitting portion 141 is recessed upward to form a notch 143. The notch 143 is conducive to increasing the elasticity of the bottom of the inner tube 14, thereby facilitating the insertion of the inner tube 14 into the lower tube section 112. The upper edge of the notch 143 is substantially flush with the lower edge of the opening 142, so as to improve the elasticity of the bottom of the inner tube 14 while ensuring strength.

[0055] See also Figure 3 and Figure 4 In some embodiments, the guide matching portion 141 of the inner tube 14 is a protrusion formed by radially protruding outward from the tube wall of the inner tube 14. The protrusion can enter the spiral guide groove 131 and slide along the spiral guide groove 131. The protrusion can have a shape that matches the spiral guide groove 131. Figure 7 For example, the protrusion can be arranged obliquely on the surface of the inner tube 14 , and its inclination angle is consistent with the inclination angle of the spiral guide groove 131 .

[0056] See also Figure 5 and Figure 6 In some embodiments, a groove 1410 is formed on the side of the protrusion facing away from the barrel 13. That is, the protrusion is formed by protruding radially outward from the entire tube wall of the inner tube 14. In other words, the tube wall of the inner tube 14 at the corresponding protrusion is the same thickness as the tube wall at other positions. By forming the groove 1410 on the side of the protrusion facing away from the barrel 13, the elasticity of the protrusion can be increased, which facilitates the insertion of the inner tube 14 into the lower tube section 112, and is also conducive to fine-tuning the size of the guide matching portion 141 so that the guide matching portion 141 can enter the spiral guide groove 131.

[0057] See also Figure 7 and Figure 8In some embodiments, the lower tube section 112 has a stopper 1122, and the cylinder 13 has a stopper matching portion 132, and the axial positioning of the cylinder 13 and the lower tube section 112 is achieved by the cooperation between the stopper 1122 and the stopper matching portion 132. In such an embodiment, the cylinder 13 and the lower tube section 112 can rotate relative to each other in the circumferential direction, but cannot move relative to each other in the axial direction, so as to prevent the cylinder 13 and the lower tube section 112 from being separated.

[0058] In some embodiments, the spiral guide groove 131 is formed on the cylinder wall 130 of the cylinder member 13 below the limiting fitting portion 132. There is a gap between the upper cylinder section 135 of the cylinder member 13 above the limiting fitting portion 132 and the pipe section of the lower pipe section 112 above the limiting portion 1122 (i.e., the lower pipe upper section 1123), and the outer diameter of the upper cylinder section 135 can be the same as the outer diameter of the upper pipe member 11. The inner wall of the upper cylinder section 135 can also be provided with a plurality of protrusions 133, and the plurality of protrusions 133 are arranged at intervals along the circumference of the upper cylinder section 135. The protrusions 133 can contact the radial outer surface of the lower pipe upper section 1123, thereby reducing the rotational friction between the upper cylinder section 135 and the lower pipe upper section 1123, and at the same time can ensure the coaxiality of the two.

[0059] In some embodiments, the upper pipe section 111 and the lower pipe section 112 of the pipe member 11 are an aluminum integral piece. In some embodiments, the receiving member 12 and the receiving member 12 are an aluminum integral piece. In some embodiments, the cylinder member 13 is an aluminum integral piece.

[0060] In some embodiments, the pipe member 11 , the receiving member 12 , the receiving member 12 , and the cylinder member 13 are all aluminum members made of aluminum.

[0061] like Fig. 9 As shown, the packaging assembly provided by the embodiment of the present application may further include: a cover body 15 and a base 16. The cover body 15 is used to form a cavity surrounding the upper pipe section 111 together with the base 16. The base 16 can form a receiving groove with an opening, the opening of the receiving groove faces the cover body 15, the cylinder 13 is installed on the base 16, and the bottom end of the upper pipe section 111 of the pipe fitting 11 is located in the receiving groove. The cover body 15 can form a receiving groove with an opening, the opening of the receiving groove faces the base 16. When using the packaging assembly, the pipe fitting 11 can be rotated while holding the base 16 to screw the rod-shaped material out of the pipe fitting 11 or screw the rod-shaped material into the pipe fitting 11.

[0062] In some embodiments, the thickness of the barrel wall 130 of the barrel 13 is uniformly set along the axial direction, and the outer surface of the barrel wall 130 protrudes radially outward at the position corresponding to the spiral guide groove 131. In such an embodiment, the groove wall of the spiral guide groove 131 forms a spirally extending rib 134 on the outer surface of the barrel wall 130. When the barrel 13 is glued to the receiving groove of the base 16 by glue, etc., these spirally extending ribs 134 and the spirally extending grooves between the ribs 134 can increase the viscosity, so that the barrel 13 is not easy to rotate relative to the base 16, thereby ensuring that when the pipe 11 is rotated relative to the base 16, the rod-shaped material can be screwed out of the pipe 11 or the rod-shaped material can be screwed into the pipe 11.

[0063] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0064] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
