Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0037] In this application, the terms "comprises" and "has" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those units explicitly listed, but may include other units not explicitly listed or inherent to these products or devices.

[0038] See also Figure 1 to Figure 6 An embodiment of the present application provides a packaging tube for improving the operating feel, including a storage element 100, a driving element 200, a guiding element 300 and a damping element 400.

[0039] The storage element 100 is used to store cosmetics, wherein the cosmetics specifically refer to pastes such as lipsticks and lip glosses. The driving element 200 is a tubular structure, and the inner wall is provided with a spiral groove 210 for driving the storage element 100. The guiding element 300 partially extends into the driving element 200 and rotates therewith, and is used to guide the storage element 100 to move axially when the two rotate relative to each other. The damping element 400 is a tubular structure, rotatably inserted on the driving element 200, and a positioning mechanism is provided between the damping element 400 and the guiding element 300 to limit the relative rotation of the two. One of the damping element 400 and the driving element 200 is provided with a ring gear 220, and the other is provided with an elastic clamping tooth 410 that cooperates with the ring gear 220.

[0040] When the guiding element 300 and the driving element 200 are rotated relative to each other, the elastic latch 410 and the gear ring 220 switch between engagement and mutual extrusion, which has a certain damping feeling, thereby improving the feel of use and the user experience of consumers. On the other hand, compared with the prior art, fewer parts are used, which not only reduces costs but also facilitates assembly.

[0041] In this embodiment, an elastic latch 410 is provided at the bottom of the damping element 400, and a corresponding driving element 200 is provided with a gear ring 220. Considering the stability of the structure when the two cooperate, the number of the elastic latch teeth 410 is multiple and evenly arranged along the circumferential direction. In the figure, the number of the elastic latch teeth 410 is 2 and they are symmetrically arranged.

[0042] See also Figure 1 and Figure 5In order to make the elastic tooth 410 have greater elasticity, a through-wall hole 420 (the through-wall hole 420 extends along the circumferential direction) is provided on the damping element 400, and an elastic strip 430 is formed between the through-wall hole 420 and the bottom of the damping element 400, and the elastic tooth 410 is provided on the elastic strip 430. Preferably, the elastic tooth 410 is located in the middle position of the elastic strip 430.

[0043] See also Figure 3-4 , a radially enlarged convex ring 310 is provided on the guide element 300, and the driving element 200 and the damping element 400 are both against the lower end surface of the convex ring 310. In order to prevent the damping element 400 and the guide element 300 from circumferential movement, in this embodiment, the positioning mechanism includes a positioning block 311 provided on the lower end surface of the convex ring 310 and a positioning groove 440 provided on the damping element 400 and cooperating with the positioning block 311, wherein the positioning groove 440 is provided on the top of the damping element 400, and the number thereof can be set according to demand. In the figure, the number is 6, and they are evenly arranged along the circumference.

[0044] See also Figure 3 to Figure 6 In order to limit the circumferential movement of the storage element 100 relative to the guide element 300, the guide element 300 is provided with a guide groove 320 arranged along the axial direction, and the outer wall of the storage element 100 is provided with a protrusion 121 that passes through the guide groove 320 and cooperates with the spiral groove 210. The protrusion 121 is located at the bottom end of the storage element 100, and the outer surface is provided with an external thread that cooperates with the spiral groove 210. In order to make the circumferential force more uniform, the number of the guide groove 320 and the protrusion 121 are respectively 2, and they are symmetrically arranged.

[0045] The storage element 100 includes a cylinder 110 and a transmission rod 120 with a protrusion 121. The transmission rod 120 is a hollow structure connected to the cylinder 110. When the driving element 200 rotates relative to the guiding element 300, the storage element 100 is driven to slide axially along the guide groove 320 of the guiding element 300.

[0046] Furthermore, the cylinder 110 and the transmission rod 120 are connected by a clamping connection, for example Figure 6 In the figure, the cylinder 110 has an annular protrusion 111 and an axially arranged groove 112 (the number of the grooves 112 is multiple and evenly arranged along the circumferential direction), and the top of the transmission rod 120 is provided with a groove 122 that cooperates with the annular protrusion 111 and a positioning rib 123 that cooperates with the groove 112. The groove 122 cooperates with the annular protrusion 111 to achieve axial limitation, and the groove 112 cooperates with the positioning rib 123 to achieve circumferential limitation.

[0047] The packaging tube of the present application also includes a decorative element 500 fixedly connected to the guide element 300 and gap-matched with the storage element 100 (the storage element 100 is hidden in the decorative element 500 and axially slides), and the decorative element 500 abuts against the upper end surface of the convex ring 310. Since the top of the existing decorative element 500 is generally an oblique opening, in order to determine the direction of the oblique opening in the packaging tube, a positioning protrusion 330 is provided on the upper end surface of the convex ring 310, and correspondingly, a notch 510 adapted to the positioning protrusion 330 is provided at the bottom of the decorative element 500. Among them, the outer surfaces of the decorative element 500, the convex ring 310 and the damping element 400 are flush, making the overall shape more beautiful and improving the ornamental value.

[0048] When assembling the packaging tube, the protrusion 121 of the transmission rod 120 can be first extended into the guide groove 320 of the guide element 300 to form the first part, and then the damping element 400 and the driving element 200 are matched to form the second part. Then the first part and the second part are assembled, and then the cylinder 110 and the transmission rod 120 are clamped together. Finally, the decorative element 500 and the guide element 300 can be matched and fixed by dotting, and the assembly is completed.

[0049] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0050] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
