[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. 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 "having" 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 with improved feel in use, 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 lipstick, lip gloss and other paste-like cosmetics. 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 is sleeved on the outer periphery of the driving element 200 and rotates with it (for example, Figure 5-6 The driving element 200 is provided with an annular protrusion 220, and the guiding element 300 is provided with an annular groove 330, and the two cooperate to achieve axial limitation). When the driving element 200 rotates relative to the guiding element 300, the guiding element 300 guides the storage element 100 to move axially.

[0040] The damping element 400 is fixedly inserted into the driving element 200. For example, as shown in the figure, a limiting ring 230 is provided on the outer peripheral wall of the driving element 200, and correspondingly, a limiting groove 420 cooperating with the limiting ring 230 is provided on the inner wall of the damping element 400. The limiting ring 230 and the limiting groove 420 cooperate with each other to achieve axial limitation. In order to achieve circumferential limitation, the driving element 200 is arranged with an axially extending positioning rib 240, and the damping element 400 is arranged with a positioning groove 430 cooperating with the positioning rib 240. The two cooperate to achieve circumferential limitation.

[0041] The bottom end of the guide element 300 is provided with a gear ring 310 , and the top end of the damping element 400 has a notch 410 . An elastic part 411 is provided in the notch 410 to span both sides thereof, and a latching tooth 412 meshing with the gear ring 310 is provided on the elastic part 411 .

[0042] When the guiding element 300 rotates relative to the driving element 200 (the damping element 400 and the driving element 200 move synchronously), since the bottom end of the guiding element 300 is provided with a gear ring 310 and the damping element 400 is provided with a corresponding latch tooth 412, the two cannot rotate smoothly, and the latch tooth 412 is on the elastic part 411. The elastic part 411 is elastic and can be pressed downward (deformed), and then restore to its original position by elasticity, so the latch tooth 412 can rotate in the gear ring 310. The latch tooth 412 will make a sound every time it rotates one tooth relative to the gear ring 310. The rotation angle can be judged by the number of sounds, and the consumer can control the amount of cosmetics extruded. In addition, the structure has a damping feeling, which improves the consumer's feel when using it.

[0043] See also Figure 4-5In the figure, the elastic part 411 is specifically an arched structure. In order to cooperate with the gear ring 310, the latching tooth 412 partially exposes the notch 410, and the ratio of the height of the latching tooth 412 exposed from the notch 410 to the height of the latching tooth 412 is 0.6-0.85:1. Considering the stability of the latching tooth 412 when cooperating with the gear ring 310, the number of the latching teeth 412 is multiple. In this embodiment, the number of the latching teeth 412 is 2 and symmetrically arranged. Of course, the number of the latching teeth 412 can be adaptively selected according to the needs, and this application does not make special requirements.

[0044] In one embodiment, the storage element 100 includes a cylinder 110 and a transmission rod 120. The cylinder 110 is a cup-shaped structure. The transmission rod 120 is a hollow structure connected to the cylinder 110, and the outer wall has an external thread 121 that matches the spiral groove 210. Preferably, the external thread 121 is located at the bottom end of the transmission rod 120. In this embodiment, the transmission rod 120 and the cylinder 110 are an integrated structure.

[0045] In order to limit the circumferential rotation of the storage element 100, the top of the guide element 300 has a limiting hole 320 for the transmission rod 120 to extend into and to limit the circumferential position of the storage element 100. Of course, in order to prevent the transmission rod 120 from separating from the guide element 300 during use, the transmission rod 120 is provided with a limiting block 122 to limit the transmission rod 120 from separating from the guide element 300. Considering the problem that the limiting block 122 can smoothly extend into the limiting hole 320, the bottom of the limiting block 122 has a guiding inclined surface.

[0046] Furthermore, the packaging tube further comprises a decorative element 500 fixedly connected to the guide element 300 and loosely matched with the storage element 100. The outer surfaces of the decorative element 500, the guide element 300 and the damping element 400 are flush, making the overall shape more beautiful and improving the ornamental value.

[0047] When the packaging tube is assembled, the damping element 400 can be first inserted into the driving element 200 from below the driving element 200 and then pressed into place, and then the transmission rod 120 of the storage element 100 is extended into the limiting hole 320 of the guiding element 300. Then, the above elements are matched (that is, the transmission rod 120 is rotated to the bottom along the spiral groove 210, and the driving element 200 and the guiding element 300 are buckled together), and finally the decorative element 500 is put on the guiding element 300 and fixed with dots to complete the installation.

[0048] 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.

[0049] 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.
