The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying 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 that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this application, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a system, product, or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.

[0024] See Figures 1-5 The cover of the packaging tube in this application includes an inner cover 100, an outer cover 200, and an elastic element 300.

[0025] The outer cover 200 includes a front section 210 and a rear section 220. The front section 210 and rear section 220 in this application are relative terms. For ease of explanation, please refer to... Figure 1 The section near the top of the inner cover 100 is the front section 210, and the section near the bottom is the rear section 220.

[0026] The front section 210 is fixedly connected to the inner cover 100, and the rear section 220 is rotatable relative to the inner cover 100. In one embodiment, an axial limiting structure and a circumferential limiting structure are provided between the inner cover 100 and the front section 210. As shown in the figure, the axial limiting structure includes a positioning groove 120 disposed on the inner cover 100 and a positioning block 211 disposed on the inner wall of the front section 210 and cooperating with the positioning groove 120. The circumferential limiting mechanism includes a protruding ring 130 disposed on the inner cover 100 and a slot 212 disposed on the front section 210 and cooperating with the protruding ring 130. In this application, the inner cover 100 may be made of PP material, and the front section 210 and the rear section 220 may be made of ABS material.

[0027] An elastic element 300 is arranged between the inner cover 100 and the rear section 220. The elastic element 300 abuts against the inner wall of the rear section 220 or the outer wall of the inner cover 100 to increase the rotational friction between the rear section 220 and the inner cover 100.

[0028] In one embodiment, the elastic element 300 is disposed on the outer wall of the inner cover 100 and abuts against the inner wall of the rear section 220. When rotated, the elastic element 300 provides a damping feel.

[0029] In one embodiment, there is a gap between the inner cover 100 and the rear section 220, and the elastic element 300 is arranged within the gap.

[0030] The cover of this application is configured with an outer cover 200 consisting of a front section 210 fixed to the inner cover 100 and a rear section 220 that rotates relative to the inner cover 100. An elastic element 300 is provided between the inner cover 100 and the rear section 220, allowing the rear section 220 to be rotated and played with relative to the inner cover 100. Compared with the prior art, this provides a cover that can be played with independently, bringing a new user experience to consumers.

[0031] In one embodiment, the front section 210 and the rear section 220 are joined together and their outer surfaces are flush, making the outer cover 200 more flat and smooth overall, thus improving its aesthetics. Furthermore, the inner cover 100 is hidden inside the outer cover 200, which not only allows the outer cover 200 to protect the inner cover 100 but also prevents the inner cover 100 from being exposed, further simplifying the overall visual appearance of the cover and making it more concise and unified.

[0032] In one embodiment, the elastic element 300 is a thin sheet structure protruding from the surface of the inner cover 100, which undergoes bending deformation during assembly. This ensures that the elastic element 300 remains in a bent deformation state when the rear section 220 rotates relative to the inner cover 100, increasing the rotational friction between the two and providing a damped feel.

[0033] In one embodiment, the elastic elements 300 are a plurality of those arranged at circumferential intervals. The specific number can be selected adaptively; for example, in the figure, the number of elastic elements 300 is specifically four.

[0034] In one embodiment, the elastic element 300 extends with a uniform width in the circumferential direction. This structure enables the force-bearing area of ​​each elastic element 300 in the circumferential direction to be evenly distributed, avoiding the damping feel from fluctuating due to uneven local force.

[0035] In one embodiment, the inner cover 100 includes a limiting portion 110 for axial positioning of the rear section 220, and the rear section 220 includes a plurality of spaced-apart protrusions 221 that abut against the limiting portion 110 (see...). Figure 5The protrusion 221 reduces friction when the rear section 220 rotates relative to the inner cover 100, resulting in smoother rotation. See, for example... Figure 5 There are 3 protrusions 221, which are evenly distributed around the circumference.

[0036] Regarding the limiting part 110, see, for example, [reference needed]. Figure 1 and Figure 3 The limiting part 110 is located at the bottom of the inner cover 100, for example, it can be formed by folding the bottom of the inner cover 100 outward. When assembling, the rear part 220 is put on the inner cover 100 from the top until the protrusion 221 abuts against the limiting part 110, and then the front part 210 is engaged and fixed to the inner cover 100 to realize the assembly of the cover.

[0037] In one embodiment, the outer surface of the inner cover 100 has an annular protrusion 140, which can reduce the gap between the inner cover 100 and the rear section 220, ensuring that the two remain centered and concentric during rotation.

[0038] When in use, you can apply a rotational force directly to the front section 210. At this time, the inner cover 100 moves synchronously with the outer cover 200. Alternatively, you can hold the front section 210 with one hand and apply a rotational force to the rear section 220 with the other hand. At this time, the rear section 220 will rotate relative to the front section 210, thereby achieving the play effect of the front section 210 and the rear section 220 of the outer cover rotating relative to each other.

[0039] See Figure 6 An embodiment of this application also discloses a packaging tube, including a base 400, a storage element, and a cover as described above. The storage element is fixedly connected to the base 400, and the cover and the base 400 together form a receiving cavity for accommodating the storage element.

[0040] The storage element can adopt an existing structure, such as a storage element for holding cosmetics, a drive element with a threaded inner wall and a guide element rotatably connected to the drive element. The storage element engages with the threaded part, and the guide element restricts the rotation of the storage element. During the relative rotation of the drive element and the guide element, the drive element drives the storage element to move axially.

[0041] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0042] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
