Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a cosmetic packaging tube for press-operated use. Background Technology

[0002] With rising living standards, cosmetics have become indispensable items in daily life. To meet diverse consumer needs, existing cosmetic packaging tubes come in various shapes and sizes, generally including a central core, a base, and a top cap. The central core comprises a storage element for holding the cosmetics, a guiding element, and a driving element. The driving element rotates in conjunction with the guiding element and has internal spiral grooves. When the driving element rotates relative to the guiding element, the spiral grooves drive the storage element to move axially within the guiding element. Consumers can unscrew the cosmetics from the central core by rotating or pressing. In existing press-type packaging tubes, pressing is typically used to rotate the storage element, allowing the cosmetics to be unscrewed. However, when using this type of packaging tube, the unscrewing of the cosmetics from the storage element is not stable enough. Summary of the Invention

[0003] This invention provides a cosmetic packaging tube for press-operated use, which solves the problem of unstable cosmetic dispensing in the prior art.

[0004] This application provides a cosmetic packaging tube for press-operated use, comprising:

[0005] The middle core includes a storage element, a guide element, and a drive element. The storage element is used to store cosmetics. The drive element is rotatably engaged with the guide element and has a spiral groove inside that is rotatably engaged with the storage element. When the drive element rotates relative to the guide element, the spiral groove drives the storage element to move axially within the guide element.

[0006] The base is inserted and fitted with the middle core, and has an axially extending channel inside. The inner wall of the channel is provided with a plurality of protrusions arranged circumferentially, and an axially extending slide is formed between adjacent protrusions.

[0007] The pressing component is movably disposed within the channel of the base and is provided with multiple protruding teeth arranged circumferentially and cooperating with the slide rail.

[0008] A transmission component is provided with a transmission structure between itself and the driving element or the guiding element, which allows the two to move relative to each other axially while restricting circumferential movement. The transmission component is provided with transmission teeth that cooperate with the slide rail and mesh with the convex teeth.

[0009] An elastic element, with both ends abutting against the transmission element and the driving element or guiding element, is used to drive the transmission element to reset;

[0010] In use, the pressing member moves axially within the channel, driving the transmission member to move axially. After the transmission teeth disengage from the slide, the transmission member is driven to rotate circumferentially, thereby driving the driving element or the guiding element to rotate synchronously.

[0011] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0012] Optionally, the end of the protrusion has a guide ramp that guides the transmission member to rotate into the next slide.

[0013] Optionally, the storage element includes a cylinder and a transmission rod, the guide element has a positioning hole, the cylinder is hidden inside the guide element, and the transmission rod passes through the positioning hole and engages with the spiral groove.

[0014] Optionally, the driving element includes a helical segment with a helical groove, a first transition segment that is clearance-fitted with the transmission rod, and a first diameter-expanding segment, wherein a first step is formed at the junction of the first diameter-expanding segment and the first transition segment.

[0015] Optionally, the transmission component includes a second transition section and a second expansion section, wherein a second step is formed at the junction of the second expansion section and the second transition section, and the elastic element is installed between the first step and the second step.

[0016] Optionally, the second diameter expansion section has an isolation sleeve at its middle position that connects with the second transition section, and the elastic element is arranged around the isolation sleeve.

[0017] Optionally, the first diameter-expanding section is movably fitted within the second diameter-expanding section.

[0018] Optionally, the transmission structure includes a positioning groove disposed on the inner wall of the second expanded diameter section and a positioning rib located on the first expanded diameter section and cooperating with the positioning groove.

[0019] Optionally, the pressing member includes a connector and a pressing cap axially fixed to the connector, and the protruding teeth are disposed on the connector.

[0020] Optionally, the inner wall of the base is provided with an annular step to restrict the connector from dislodging, and the protrusion extends to the annular step.

[0021] Optionally, the pressing member has a hollow structure, and the transmission rod extends into the connecting member.

[0022] When the cosmetic packaging tube of this application is used, the pressing element moves axially within the channel, driving the transmission element to move axially. After the transmission teeth disengage from the slide, the transmission element is driven to rotate circumferentially, thereby driving the driving element or the guiding element to rotate synchronously. Compared with the prior art, the storage element of this application does not need to rotate and move up and down, making the cosmetic pressing more stable. Attached Figure Description

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. 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.

[0046] 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.

[0047] 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.

[0048] See Figures 1-4 One embodiment of this application provides a cosmetic packaging tube for pressing, including a central core 100, a base 200, a pressing component 300, a transmission component 400, and an elastic component 500.

[0049] The central 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 is rotatably engaged with the guide element 120 and has a spiral groove 132 inside 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 central core 100, the cosmetic packaging tube also includes a top cover 600, which is flush with the outer surface of the base 200, making the appearance more aesthetically pleasing.

[0050] The applicable core structure can be of various types. For example, a protrusion can be provided on the storage element 110, and a corresponding axial guide groove can be provided on the guide element 120. The protrusion extends out of the guide groove and cooperates with the spiral groove 132 of the drive element 130.

[0051] For example, storage element 110 includes cylinder 111 and transmission rod 112. Guiding element 120 is provided with positioning hole 121. Cylinder 111 is hidden in guiding element 120. Transmission rod 112 passes through positioning hole 121 and cooperates with spiral groove 132.

[0052] Furthermore, the base 200 is inserted into the middle core 100 and has an axially extending channel 210 inside. The inner wall of the channel 210 has a plurality of circumferentially arranged protrusions 220, and adjacent protrusions 220 form axially extending slides 230. Of course, the number of slides 230 can be set according to the requirements. For example, in this embodiment, there are 8 slides 230, which are evenly distributed circumferentially.

[0053] The pressing element 300 is movably disposed within the channel 210 of the base 200, and is provided with a plurality of protruding teeth 311 arranged circumferentially and cooperating with the slide rail 230. Accordingly, the number of protruding teeth 311 is 8.

[0054] A transmission structure is provided between the transmission component 400 and the drive element 130 or the guide element 120, which allows the two to move axially relative to each other but restricts circumferential movement. The transmission component 400 is provided with transmission teeth 411 that cooperate with the slide 230 and mesh with the convex teeth 311. Considering the stability of the structure during use, the number of transmission teeth 411 is at least 2. In this embodiment, 4 are specifically provided and are evenly arranged circumferentially.

[0055] The elastic element 500 abuts against the transmission element 400 and the driving element 130 or the guiding element 120 at both ends, and is used to drive the transmission element 400 to reset.

[0056] In practical use, the pressing member 300 moves axially within the channel 210, driving the transmission member 400 to move axially. After the transmission gear 411 disengages from the slide 230, it drives the transmission member 400 to rotate circumferentially, thereby driving the driving element 130 or the guiding element 120 to rotate synchronously (so that the storage element 110 climbs and moves upward within the spiral groove 132). Compared with the prior art, the storage element 110 of this application does not need to rotate and move up and down, making the cosmetic pressing more stable.

[0057] For ease of explanation, the illustrations in this application use the structure described above, where the storage element is equipped with a transmission rod, and in use, the transmission component 400 drives the drive element 130 to rotate. Other core structures will not be described in this application.

[0058] See Figure 3 In this embodiment, the protruding tooth 311 includes a base 312 and an extension 313 arranged axially around the outer periphery of the base 312 (the extension 313 is located in the middle of the base 312, and the top of both forms a tooth tip). The bases 312 of the plurality of protruding teeth 311 form a tooth ring, and the extension 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, the bottom angle is the same as that of one side of the inclined surface of the protrusion 311, making the structure more stable during use. Considering that the transmission component 400 can rotate smoothly when pressed, the end of the protrusion 220 has a guide slope 221 to guide the transmission component 400 to rotate into the next slide 230.

[0060] See Figures 5a-5eThis is a schematic diagram illustrating the interaction of a transmission gear 411, a slide rail 230, and a convex tooth 311 during the axial movement of the pressing component 300 to its reset position. Specifically, Figure 5a In the initial state, the transmission tooth 411 abuts against the convex tooth 311 within the slide rail 230. Due to the circumferential limiting effect of the slide rail 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 tooth 311 pushes against the transmission tooth 411 to make axial movement. Then, when the transmission tooth 411 continues to move axially until it disengages from the slide 230 (see...), Figure 5c The circumferential direction is no longer restricted, and it can rotate relative to the tooth 311 until it abuts against the root of the tooth 311 (base 312). Then, after the force is released, the pressing member 300 is reset under the action of the elastic member 500. During this process, the 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 and enters the next slide 230, thus completing one pressing (multiple pressings can be performed according to actual needs). The structure of this application is unidirectional rotation, which can push out cosmetics and cannot retract them, reducing the pollution of cosmetics and making it more environmentally friendly and hygienic.

[0061] To facilitate the installation of the elastic element 500, such as Figure 6 As shown, the driving element 130 of this application includes a helical segment 131 with a helical groove 132, a first transition segment 133 that is clearance-fitted with the transmission rod 112, and a first diameter-expanding segment 134. A first step 136 is formed at the junction of the first diameter-expanding segment 134 and the first transition segment 133. Furthermore, an annular portion 137 is provided at the top of the helical segment 131, and a corresponding groove 125 is provided on the guide element 120. The two cooperate to achieve circumferential limiting.

[0062] The transmission component 400 includes a second transition section 410 and a second expansion section 420. The junction of the second expansion section 420 and the second transition section 410 forms a second step 430. The elastic component 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 with by the elastic element 500 when it rotates, the middle position of the second expansion section 420 has an isolation sleeve 412 that connects with the second transition section 410, and the elastic element 500 is arranged around the isolation sleeve 412.

[0064] Preferably, the first expansion section 134 is movably fitted inside the second expansion section 420, making the overall appearance more aesthetically pleasing and limiting 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 disposed on the inner wall of the second expanded diameter section 420 and a positioning rib 135 located on the first expanded diameter 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 insertion and cooperation of the two.

[0066] See Figure 1 and Figure 3 The pressing component 300 includes a connector 310 and a pressing cap 320 axially fixed to the connector 310, with protruding teeth 311 disposed on the connector 310. The pressing cap 320 of this application is partially exposed on the base 200 for easy pressing. In use, the user can hold the base 200 firmly with one hand and press down on the pressing cap 320 with their thumb (pressing can be repeated multiple times) to push out the cosmetic for use.

[0067] In one embodiment, see Figure 4 The inner wall of the base 200 is provided with an annular step 240 that restricts the connector 310 from dislodging. 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 connector 310 abuts against the annular step 240.

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

[0069] During the assembly of the packaging tube of this application, the storage element 110 and the guide element 120 are first assembled, and then the assembled parts are screwed into the drive element 130, thus completing the assembly of the middle core 100. Next, the connector 310 can be placed in the base 200, the pressing cap 320 is pressed into place with the connector 310, then the transmission element 400 is placed in, and then the elastic element 500 is installed. Then it is assembled with the middle core 100, and the top cover 600 is put on, thus completing the assembly of the packaging tube.

[0070] In one embodiment, see Figure 8 To increase the airtightness of the cosmetic packaging tube, an interference fit snap-fit ​​structure is provided between the top cover 600 and the guide element 120. Furthermore, this application also provides a sealing ring 114. To facilitate installation, a groove 113 is provided on the outer peripheral wall of the cylinder 111, and 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 central core 100 from the base 200, the top of the base 200 is provided with an annular protrusion 201 and an axially arranged slot 202. The guide element 120 is provided with an annular groove 123 and a rib 124. The annular protrusion 201 and the annular groove 123 cooperate to achieve axial positioning, and the slot 202 and the rib 124 cooperate to achieve circumferential positioning.

[0072] Furthermore, the isolation sleeve of the transmission component 400 is also provided with a convex ring 413, which can restrict the elastic element 500 from falling out, so as to avoid the problem of the elastic element 500 falling off when disassembling the core 100.

[0073] See Figure 10 The cosmetic product of this application can be a solid structure such as lipstick or lip gloss, or a viscous liquid such as lip gloss. When the cosmetic product is lip gloss, a brush head 122 can be installed and fixed on the top of the guide element 120.

[0074] See 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 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.

[0076] 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.
