[0046] 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 technical features indicated. 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, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0047] In this application, the terms "comprises" and "comprising" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or apparatus comprising a list of elements is not necessarily limited to those elements expressly listed but may include other elements not expressly listed or inherent to such products or apparatuses.

[0048] See also Figures 1 to 4 An embodiment of the present application provides a cosmetic packaging tube for pressing, including a middle bundle core 100, a base 200, a pressing member 300, a transmission member 400 and an elastic member 500.

[0049] The center bundle core 100 includes a storage element 110, a guide element 120, and a drive element 130. The storage element 110 is used to store cosmetics. The drive element 130 rotatably engages with the guide element 120 and is internally provided with a spiral groove 132 that rotatably engages with the storage element 110. When the drive element 130 rotates relative to the guide element 120, the spiral groove 132 drives the storage element 110 to move axially within the guide element 120. To protect the center bundle core 100, the cosmetic packaging tube also includes a top cover 600, which is flush with the outer surface of the base 200, enhancing the appearance.

[0050] There are various mid-beam core structures applicable to the present application. For example, a protrusion may be provided on the storage element 110 , and a corresponding axial guide groove may be provided on the guide element 120 . The protrusion extends out of the guide groove and cooperates with the spiral groove 132 of the driving element 130 .

[0051] For another example, the storage element 110 includes a cylinder 111 and a transmission rod 112 . A positioning hole 121 is provided in the guide element 120 . The cylinder 111 is hidden in the guide element 120 . The transmission rod 112 passes through the positioning hole 121 and cooperates with the spiral groove 132 .

[0052] Furthermore, the base 200 is plugged into and matched with the middle beam core 100, and a channel 210 extending in the axial direction is provided inside. The inner wall of the channel 210 is provided with a plurality of protrusions 220 arranged in the circumferential direction, and a slide 230 extending in the axial direction is formed between adjacent protrusions 220. Of course, the number of slides 230 can be set according to needs. For example, in this embodiment, the number of slides 230 is 8, and they are evenly distributed in the circumferential direction.

[0053] The pressing member 300 is movably disposed in the channel 210 of the base 200 and is provided with a plurality of protruding teeth 311 arranged along the circumferential direction and matched with the slideway 230 . Accordingly, the number of the protruding teeth 311 is eight.

[0054] A transmission structure is provided between the transmission member 400 and the driving element 130 or the guiding element 120, which allows the two to move axially relative to each other while restricting circumferential movement. The transmission member 400 is provided with transmission teeth 411 that cooperate with the slideway 230 and mesh with the convex teeth 311. Considering the stability of the structure during use, the number of transmission teeth 411 is provided at least 2, and in this embodiment, specifically 4 are provided, and are evenly arranged along the circumference.

[0055] Two ends of the elastic member 500 abut against the transmission member 400 and the driving element 130 or the guiding element 120 to drive the transmission member 400 to reset.

[0056] During specific use, the pressing member 300 moves axially in the channel 210, driving the transmission member 400 to move axially. After the transmission tooth 411 disengages from the slide 230, the transmission member 400 is driven to rotate circumferentially, thereby driving the driving element 130 or the guide element 120 to rotate synchronously (so that the storage element 110 climbs and moves upward in the spiral groove 132). Compared with the prior art, the storage element 110 of the present application does not need to rotate up and down, and the cosmetic pressing is more stable.

[0057] For ease of explanation, the diagrams in this application illustrate the above-mentioned storage element with a transmission rod, and in use, the transmission member 400 drives the driving element 130 to rotate. Other mid-beam core structures will not be described in this application.

[0058] See also Figure 3 In this embodiment, the protruding tooth 311 includes a base 312 and an extension portion 313 arranged axially around the outer periphery of the base 312 (the extension portion 313 is located in the middle position of the base 312, and the tops of the two form a tooth tip). The bases 312 of multiple protruding teeth 311 form a gear ring, and the extension portion 313 can move axially in the slide 230.

[0059] In this embodiment, see Figure 4 The bottom of the transmission tooth 411 is inclined, preferably at the same angle as the inclined surface of the protruding tooth 311, making the structure more stable during use. In order to ensure that the transmission member 400 can rotate smoothly when pressed, the end of the protrusion 220 has a guide inclined surface 221 to guide the transmission member 400 to rotate into the next slide 230.

[0060] See also Figures 5a to 5e, is a schematic diagram showing the cooperation between a transmission tooth 411, a slideway 230 and a protruding tooth 311 during the axial movement of the pressing member 300 to the reset state. Figure 5a In the initial state, the transmission tooth 411 abuts against the convex tooth 311 in the slideway 230. Due to the circumferential limit of the slideway 230, the transmission tooth 411 cannot rotate relative to the convex tooth 311. When the pressing member 300 moves axially (see Figure 5b ), the convex teeth 311 push the transmission teeth 411 to make axial movement, and then when the transmission teeth 411 continue to move axially to disengage the slideway 230 (see Figure 5c ), the circumferential direction is no longer restricted, and it can rotate relative to the convex tooth 311 until it abuts against the root of the convex tooth 311 (base 312). Then, after the force is withdrawn, the pressing member 300 is reset under the action of the elastic member 500. During this process, the convex tooth 311 moves downward, and the bottom of the transmission tooth 411 abuts against the guide slope 221 of the slide 230. Then, the transmission tooth 411 rotates along the guide slope 221 to enter the next slide 230, completing one press (multiple presses can be performed according to actual needs). The structure of the present application is unidirectional rotation, which can push out the cosmetics and cannot be withdrawn, reducing the pollution of the cosmetics and being more environmentally friendly and hygienic.

[0061] In order to facilitate the installation of the elastic member 500, as Figure 6 As shown, the drive element 130 of the present application includes a helical section 131 having a helical groove 132, a first transition section 133 that is clearance-matched with the transmission rod 112, and a first expanded diameter section 134. A first step 136 is formed at the intersection of the first expanded diameter section 134 and the first transition section 133. Furthermore, an annular portion 137 is provided at the top of the helical section 131, and a corresponding groove 125 is provided on the guide element 120, and the two cooperate to achieve circumferential limiting.

[0062] The transmission member 400 includes a second transition section 410 and a second diameter-enlarging section 420 . A second step 430 is formed at the junction of the second diameter-enlarging section 420 and the second transition section 410 . The elastic member 500 is installed between the first step 136 and the second step 430 .

[0063] Of course, in order to avoid the problem that the transmission rod 112 may be interfered by the elastic member 500 when rotating, the middle position of the second expanded diameter section 420 has an isolation sleeve 412 connected with the second transition section 410, and the elastic member 500 is arranged around the isolation sleeve 412.

[0064] Preferably, the first diameter-enlarging section 134 is movably sleeved in the second diameter-enlarging section 420 , which makes the overall appearance more beautiful and can limit the upward pressing stroke of the pressing member 300 .

[0065] In this embodiment, see Figure 3 and Figure 7The transmission structure includes a positioning groove 421 provided on the inner wall of the second diameter expansion section 420 and a positioning rib 135 located on the first diameter expansion section 134 and cooperating with the positioning groove 421. Preferably, the top of the positioning groove 421 and the bottom of the positioning rib 135 are set at an angle to facilitate the plug-in fit between the two.

[0066] See also Figure 1 and Figure 3 The pressing member 300 includes a connecting member 310 and a pressing cap 320 axially fixed to the connecting member 310. The protruding teeth 311 are provided on the connecting member 310. The pressing cap 320 of the present application is partially exposed to the base 200 for easy pressing. When in use, the user can hold the base 200 tightly with one hand and press the pressing cap 320 with the thumb (this pressing can be repeated multiple times) to push out the cosmetics for use.

[0067] In one embodiment, see Figure 4 The inner wall of the base 200 is provided with an annular step 240 for limiting the connection member 310 from falling out, and the protrusion 220 extends to the annular step 240. When there is no external force pressing, under the action of the elastic member 500, the bottom of the connection member 310 is against the annular step 240.

[0068] Preferably, the pressing member 300 is a hollow structure, and the transmission rod 112 extends into the connecting member 310. This design increases the stroke of the transmission rod 112 and can load more cosmetics.

[0069] When assembling the packaging tube of the present application, the storage element 110 and the guide element 120 are first assembled, and then these assembled parts are screwed into the drive element 130, completing the assembly of the middle bundle core 100. Next, the connector 310 can be placed into the base 200, and the press cap 320 and connector 310 can be press-fitted into place. The transmission element 400 is then inserted, followed by the elastic element 500, which is then assembled with the middle bundle core 100 and covered with the top cover 600, completing the assembly of the packaging tube.

[0070] In one embodiment, see Figure 8 In order to increase the airtightness of the cosmetic packaging tube, an interference fit buckle structure is provided between the top cover 600 and the guide element 120. Furthermore, the present application also provides a sealing ring 114. For easy installation, a groove 113 is provided on the outer peripheral wall of the cylinder 111. The sealing ring 114 is installed in the groove 113 to seal the gap between the cylinder 111 and the guide element 120.

[0071] In one embodiment, see Figure 3 and Figure 9When the packaging tube is replaceable, in order to separate and disassemble the middle bundle core 100 from the base 200, an annular protrusion 201 and an axially arranged groove 202 are provided on the top of the base 200, and the guide element 120 is provided with an annular groove 123 and a rib 124. The annular protrusion 201 cooperates with the annular groove 123 to achieve axial positioning, and the groove 202 cooperates with the rib 124 to achieve circumferential positioning.

[0072] Furthermore, a convex ring 413 is provided on the isolation sleeve of the transmission member 400 . The convex ring 413 can limit the elastic member 500 from falling out, so as to avoid the problem of the elastic member 500 falling when the center beam core 100 is disassembled.

[0073] See also Figure 10 The cosmetics of the present application can be solid structures such as lipstick and lip gloss, or can be viscous liquids such as lip gloss. When the cosmetics are lip gloss, a brush head 122 can be installed and fixed on the top of the guiding element 120.

[0074] See also Figure 11 In another embodiment, the transmission rod 112 is a hollow structure, and the cylinder 111 and the transmission rod 112 are connected to enable backflow.

[0075] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they 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 deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0076] The above-described embodiments merely represent several implementation methods of the present application. 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 a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
