Packaging container for stick cosmetic product

Abstract

This application discloses a packaging container for stick-shaped cosmetics, including a central core, a base rotatably connected to the central core, a first anti-reverse mechanism, and a second anti-reverse mechanism. The central core includes a supporting element, a drive element with internal threads, and a guide element rotatably connected to the drive element. The guide element has a limiting portion. During relative rotation of the drive element and the guide element, the drive element drives the supporting element to move axially. The first anti-reverse mechanism prevents the drive element from rotating relative to the guide element in a first direction, but allows the drive element to rotate in the opposite second direction. The second anti-reverse mechanism prevents the central core from rotating relative to the base in the second direction, but allows the central core to rotate relative to the base in the opposite first direction. When the packaging container of this application rotates in the second direction, the stick-shaped cosmetic is unscrewed. When rotating in the first direction, the central core rotates as a whole, and the unscrewed position of the stick-shaped cosmetic remains unchanged, overcoming the problem of not being able to rotate in the opposite direction, and the structure is more novel.

Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a packaging container for stick-shaped cosmetics. Background Technology

[0002] Traditional lipstick tubes can be screwed on and off. However, due to the formula, some lipsticks are relatively soft, and screwing them back on after they've been unscrewed can affect their next use. To address this, lipstick tubes with unidirectional rotation have been introduced. For example, document CN214317287U discloses a unidirectional rotating core, including a spiral, beads, a middle sleeve, and a chuck fixed to the outer circumference of the spiral. The spiral has internal threads, and the bottom of the beads extends into the spiral, with the extended portion engaging with the internal threads. The middle sleeve rotates and is fitted around the outer circumference of the spiral, limiting its axial movement. When the spiral rotates relative to the middle sleeve, the middle sleeve guides the beads to move along the axial direction of the core. A unidirectional rotating structure exists between the chuck and the middle sleeve to restrict the rotation direction of the middle sleeve.

[0003] The aforementioned core can only rotate in one direction. That is, the cream can be twisted out when rotating in the forward direction, but it cannot be rotated in the reverse direction. When consumers are unaware of the structure of the core and try to rotate it in the opposite direction, the structure is easily damaged. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a packaging container for stick-shaped cosmetics.

[0005] Packaging containers for stick-shaped cosmetics, including:

[0006] The middle core includes a support element for carrying and storing the rod-shaped cosmetic, a drive element with internal threads, and a guide element rotatably connected to the drive element. The guide element has a limiting portion that prevents the support element from rotating. A portion of the support element passes through the guide element and engages with the internal threads. During the relative rotation of the drive element and the guide element, the drive element drives the support element to move axially.

[0007] The base is rotatably connected to the driving element or the guiding element;

[0008] A first anti-reverse mechanism prevents the drive element from rotating relative to the guide element in a first direction, while allowing the drive element to rotate in the opposite second direction;

[0009] The second anti-reverse mechanism prevents the middle core from rotating relative to the base in a second direction, while allowing the middle core to rotate relative to the base in the opposite first direction.

[0010] 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.

[0011] Optionally, the middle core is detachably connected to the base.

[0012] Optionally, the first anti-reverse mechanism includes a first toothed ring and a first ratchet. The first toothed ring includes a plurality of first anti-reverse teeth arranged circumferentially. The first ratchet meshes with the first anti-reverse teeth to prevent the drive element from rotating relative to the guide element in a first direction, while allowing the drive element to rotate in the opposite second direction.

[0013] One of the first toothed ring and the first ratchet is fixedly connected to the drive element, and the other is fixedly connected to the guide element.

[0014] Optionally, the first ratchet includes a first base, a first engaging portion that engages with the first anti-reverse tooth, and a first elastic portion that drives the first engaging portion to reset.

[0015] Optionally, the first elastic portion is located between the first base portion and the first engaging portion.

[0016] Optionally, the second anti-reverse mechanism includes a second toothed ring and a second ratchet. The second toothed ring includes a plurality of second anti-reverse teeth arranged circumferentially. The second ratchet meshes with the second anti-reverse teeth to prevent the middle core from rotating relative to the base in a second direction, while allowing the middle core to rotate relative to the base in the opposite first direction.

[0017] One of the second toothed ring and the second ratchet is fixedly connected to the central core, and the other is fixedly connected to the base.

[0018] Optionally, the second ratchet includes a second base, a second engagement portion that engages with the second anti-reverse tooth, and a second elastic portion that drives the second engagement portion to reset.

[0019] Optionally, the second elastic portion is located between the second base portion and the second engaging portion.

[0020] Optionally, the bearing element includes a cylinder and a transmission rod, the limiting part includes a limiting hole adapted to the transmission rod, and the transmission rod has an external thread that mates with the internal thread.

[0021] Optionally, the middle core includes an extension element connected to the guide element, the cylinder being placed in the extension element and moving within the extension element during use.

[0022] The first anti-reverse mechanism employed in this application allows the driving element to rotate relative to the guiding element in a second direction, causing the cream to be unscrewed. The second anti-reverse mechanism allows the central core to rotate relative to the base in a first direction. Therefore, when the packaging container of this application rotates in the second direction, the stick-shaped cosmetic is unscrewed; when it rotates in the first direction, the central core rotates as a whole, and the unscrewed position of the stick-shaped cosmetic remains unchanged. Compared with the traditional unidirectional rotation structure, this overcomes the problem of not being able to rotate in the opposite direction, making the structure more novel.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] See Figures 1-3 This application provides a packaging container for stick-shaped cosmetics, used to store cosmetics such as lipsticks and lip glosses. It mainly includes a central core, a base 600, a cap 800, a first anti-reverse mechanism, and a second anti-reverse mechanism. The first and second directions mentioned below are relative; unless otherwise specified, the second direction refers to the direction in which the cosmetic is rotated out, and the first direction refers to the opposite direction.

[0048] The middle core includes a support element 100, a drive element 200, and a guide element 300. The support element 100 is used to support and store the stick-shaped cosmetic. The inner wall of the drive element 200 is provided with an internal thread 210. The top of the drive element 200 is inserted into the interior of the guide element 300. An axial limiting mechanism is provided between the guide element 300 and the drive element 200. The two can rotate relative to each other in the circumferential direction, but are fixed relative to each other in the axial direction.

[0049] In one embodiment, see Figure 1 , Figure 5a as well as Figure 5b The outer periphery of the driving element 200 is provided with an annular protrusion 240, and the inner wall of the guide element 300 is provided with an annular groove 340. The annular protrusion 240 and the annular groove 340 cooperate to achieve axial positioning.

[0050] The guide element 300 has a limiting part 310 that prevents the bearing element 100 from rotating. A portion of the bearing element 100 passes through the guide element 300 and engages with the internal thread 210. During the relative rotation of the drive element 200 and the guide element 300, the drive element 200 can drive the bearing element 100 to move axially, and the limiting part 310 can restrict the bearing element 100 from rotating.

[0051] In one embodiment, the supporting element 100 includes a cylindrical body 110 and a transmission rod 120. The cylindrical body 110 is used to hold cosmetics, and the transmission rod 120 is used to engage with an internal thread 210. In order for the transmission rod 120 to pass through the guide element 300 and extend into the interior of the driving element 200, the limiting part 310 includes a limiting hole 311 adapted to the transmission rod 120. The transmission rod 120 has an external thread 121 that engages with the internal thread 210. In one embodiment, the bottom end of the transmission rod 120 also has an anti-detachment part 122. When the driving element 200 and the guide element 300 rotate relative to each other, driving the supporting element 100 to move to the top position, the anti-detachment part 122 abuts against the edge of the limiting hole 311, preventing the transmission rod 120 from disengaging from the guide element 300.

[0052] In one embodiment, the middle core further includes an extension element 700 connected to the guide element 300. The extension element 700 is fixed to the outer periphery of the guide element 300, and the cylinder 110 is placed in the extension element 700 and moves within the extension element 700 during use. The extension element 700 can support the cylinder 110, maintaining a stable posture during movement. It can also protect the cylinder 110 from external interference and damage to a certain extent, such as preventing foreign objects from entering the gap between the cylinder 110 and other components, and avoiding collisions or friction to the cylinder 110.

[0053] In one embodiment, the base 600 is rotatably connected to the central core. There are various ways the base 600 and the central core can be connected, such as the base 600 being rotatably connected to the guide element 300, or the base 600 being rotatably connected to the drive element 200. This embodiment shows the base 600 being rotatably connected to the drive element 200.

[0054] See Figures 1-4 The base 600 includes an outer bottom 610 and an inner bottom 620. The inner bottom 620 partially extends into the outer bottom 610 and is fixedly connected to the outer bottom 610. The portion exposed on the outer bottom 610 engages with the cover 800 to seal and protect the central core. In one embodiment, an axial limiting mechanism and a circumferential limiting mechanism are provided between the outer bottom 610 and the inner bottom 620. The axial limiting mechanism includes an annular groove 621 disposed on the inner bottom 620 and a protruding ring 611 disposed on the outer bottom 610. The circumferential limiting mechanism includes a first positioning rib 622 disposed on the inner bottom 620 and arranged axially, and a first positioning groove 612 disposed on the outer bottom 610. The annular groove 621 and the protruding ring 611 cooperate to achieve axial limiting, and the first positioning rib 622 and the first positioning groove 612 cooperate to achieve circumferential limiting.

[0055] In one embodiment, the bottom of the outer base 610 is provided with a weight 630. The weight 630 can lower the center of gravity of the packaging container, making it more stable when placed on a table or during use, less likely to tip over, and can also improve the texture of the product and enhance the user experience.

[0056] After the cosmetics inside the packaging container are used up, considering environmental protection and reducing waste, the central core and base 600 of this application are detachably connected. For details on the connection method, please refer to... Figures 1 to 5b An axial limiting structure is provided between the outer bottom 610 and the driving element 200. Specifically, the inner wall of the outer bottom 610 has a limiting groove 614, and the driving element 200 has a limiting protrusion 250 that cooperates with the limiting groove 614. The two cooperate to achieve axial limiting. In one embodiment, the inner wall of the outer bottom 610 has a reduced diameter limiting step 615, and a protrusion 613 is arranged above the limiting step 615. The limiting groove 614 is formed between the protrusion 613 and the limiting step 615. Since the middle core of this application can be disassembled relative to the base 600, guide slopes are arranged on the upper and lower sides of the protrusion 613 to facilitate disassembly and installation. In one embodiment, there are multiple protrusions 613 to ensure the stability of the structure. For example, there are three protrusions 613 in this application, which are evenly arranged circumferentially.

[0057] See Figure 2 , Figure 6 as well as Figure 7 The first anti-reverse mechanism prevents the drive element 200 from rotating relative to the guide element 300 in a first direction, while allowing the drive element 200 to rotate in the opposite second direction. The second anti-reverse mechanism prevents the middle core from rotating relative to the base 600 in the second direction, while allowing the middle core to rotate relative to the base 600 in the opposite first direction. Therefore, the function of the first anti-reverse mechanism is to prevent the unscrewed stick-shaped cosmetic from re-screwing back into the middle core and causing contamination, while the function of the second anti-reverse mechanism is to allow the middle core to rotate in the opposite direction as a whole, but the unscrewed length of the cosmetic remains unchanged during the rotation.

[0058] When the packaging container of this application rotates in the second direction, the stick-shaped cosmetic is unscrewed out. However, when it rotates in the first direction, the central core rotates as a whole, and the unscrewed position of the stick-shaped cosmetic remains unchanged. Compared with the traditional unidirectional rotation structure, this overcomes the problem of not being able to rotate in the opposite direction, and the structure is more novel.

[0059] When the user holds the base 600 in one hand and the extension element 700 in the other hand, and rotates the base 600 relative to the extension element 700 in the second direction (the first anti-reverse mechanism allows rotation, and the second anti-reverse mechanism restricts rotation), the drive element 200 can rotate relative to the guide element 300, the bearing element 100 moves to the top, and the ointment is gradually pushed out.

[0060] When the base 600 rotates relative to the extension element 700 in the first direction (the first anti-reverse mechanism restricts the rotation, and the second anti-reverse mechanism allows the rotation), the entire middle core can rotate relative to the base 600, the axial position of the bearing element 100 remains unchanged, and correspondingly, the twist-out length of the paste also remains unchanged.

[0061] See Figures 2-8 The first anti-reverse mechanism includes a first toothed ring 320 and a first ratchet 400. The first toothed ring 320 includes a plurality of first anti-reverse teeth 330 arranged circumferentially. The first ratchet 400 meshes with the first anti-reverse teeth 330 to prevent the drive element 200 from rotating relative to the guide element 300 in a first direction, while allowing the drive element 200 to rotate in the opposite second direction.

[0062] In one embodiment, one of the first toothed ring 320 and the first ratchet 400 is fixedly connected to the drive element 200, and the other is fixedly connected to the guide element 300. In the figure, the first toothed ring 320 is fixed to the bottom end of the guide element 300, and the first ratchet 400 is fixed to the drive element 200.

[0063] To enhance structural stability, the first toothed ring 320 and the guide element 300 are integrally formed. In one embodiment, see... Figure 2 The first anti-reverse tooth 330 is a one-way locking tooth, and each tooth tip has a first guide tooth surface 331 and a first anti-reverse tooth surface 332. The first guide tooth surface 331 is arranged obliquely along the second direction, and the first anti-reverse tooth surface 332 is located on the opposite side of the first guide tooth surface 331. The first tooth ring 320 has an end face perpendicular to the axis. The first anti-reverse tooth surface 332 is perpendicular to the end face of the first tooth ring 320. The first guide tooth surface 331 and the end face of the first tooth ring 320 form an acute angle α. Preferably, the angle α is 20° to 35°.

[0064] For details on the structure of the first ratchet 400, please refer to [link / reference]. Figures 2-8 The first ratchet 400 includes a first base 410, a first engagement portion 420 that engages with the first anti-reverse tooth 330, and a first elastic portion 430 that drives the first engagement portion 420 to reset.

[0065] In one embodiment, the first base 410 is generally cylindrical and fixedly connected to the driving element 200. For example, as shown in the figure, the outer periphery of the driving element 200 is provided with an axially extending positioning block 260 and a positioning ring 280. The inner wall of the first base 410 is provided with a slot 411 that mates with the positioning block 260 and a groove 412 that mates with the protrusion 613. The positioning block 260 and the slot 411 cooperate to achieve circumferential limiting, and the protrusion 613 and the groove 412 cooperate to achieve axial limiting. Preferably, multiple positioning blocks 260 and corresponding slots 411 are arranged to make the structure more stable.

[0066] In one embodiment, the first elastic portion 430 is located between the first base portion 410 and the first engaging portion 420. See also Figure 2The first engaging portion 420 is arranged obliquely in the circumferential direction, and a notch 413 is arranged at the top of the first base 410, which is located below the first engaging portion 420. Preferably, the axial distance between the first engaging portion 420 and the first base 410 is greater than the thickness of the first engaging portion 420, and the length of the notch 413 extending circumferentially is greater than the length of the first engaging portion 420 and the first elastic portion 430. When the first engaging portion 420 is engaged and pressed with the first anti-reverse tooth 330, the notch 413 can provide sufficient deformation space.

[0067] In one embodiment, during engagement, the first engaging portion 420 has a first surface that mates with the first anti-reverse tooth surface 332 and a second surface that mates with the first guide tooth surface 331. When the first ratchet 400 rotates relative to the first tooth ring 320, the first guide tooth surface 331 and the second surface press against each other. The first elastic portion 430 drives the first engaging portion 420 to move toward the notch 413 until it disengages from the locking tooth. After passing the locking tooth, the first engaging portion 420 resets under the action of the first elastic portion 430, engages with the adjacent locking tooth, and makes a "click" sound. When force is applied in the opposite direction, the first surface interacts with the first anti-reverse tooth surface 332, making relative rotation impossible.

[0068] In one embodiment, the second anti-reverse mechanism includes a second toothed ring 220 and a second ratchet 500. The second toothed ring 220 includes a plurality of second anti-reverse teeth 230 arranged circumferentially. The second ratchet 500 engages with the second anti-reverse teeth 230 to prevent the middle core from rotating relative to the base 600 in a second direction, while allowing the middle core to rotate relative to the base 600 in the opposite first direction.

[0069] In one embodiment, see Figures 3 to 5b One of the second toothed ring 220 and the second ratchet 500 is fixedly connected to the central core. In the figure, the second toothed ring 220 is fixed to the bottom end of the drive element 200. In one embodiment, the second toothed ring 220 and the drive element 200 are an integral structure, which enhances the stability of the structure.

[0070] See Figure 2 The second anti-reverse tooth 230 is a one-way locking tooth, and each tooth tip has a second guide tooth surface 231 and a second anti-reverse tooth surface 232. The first guide tooth surface 331 is arranged obliquely along the first direction, and the first anti-reverse tooth surface 332 is located on the opposite side of the second guide tooth surface 231. The second tooth ring 220 has an end face perpendicular to the axis. The second anti-reverse tooth surface 232 is perpendicular to the end face of the second tooth ring 220. The second guide tooth surface 231 and the end face of the second tooth ring 220 form an acute angle β. Preferably, the angle of β is 20° to 35°.

[0071] See Figures 2-4 as well as Figure 9The second ratchet 500 includes a second base 510, a second engagement portion 520 that engages with the second anti-reverse tooth 230, and a second elastic portion 530 that drives the second engagement portion 520 to reset. In one embodiment, the second ratchet 500 is fixedly connected to the outer base 610. Specifically, the second base 510 has a cylindrical structure, with an axially extending second positioning rib 511 and an annular protrusion 512 arranged on its outer periphery. The inner wall of the outer base 610 is provided with a second positioning groove 616 and an annular groove 617. The second positioning rib 511 and the second positioning groove 616 cooperate to achieve circumferential limiting, and the annular protrusion 240 and the annular groove 617 cooperate to achieve axial limiting.

[0072] In one embodiment, the second elastic portion 530 is located between the second base portion 510 and the second engagement portion 520. The second ratchet 500 is arranged obliquely in the circumferential direction. The top end of the second base portion 510 is provided with a notch 513, which is located below the second engagement portion 520. The axial distance between the second engagement portion 520 and the second base portion 510 is greater than the thickness of the second engagement portion 520. The length of the notch 513 extending circumferentially is greater than the length of the second engagement portion 520 and the second elastic portion 530. When it is pressed in conjunction with the second anti-reverse tooth 230, the notch 513 can provide sufficient deformation space for the second elastic portion 530.

[0073] In one embodiment, during engagement, the second engaging portion 520 has a first surface that mates with the second anti-reverse tooth surface 232 and a second surface that mates with the second guide tooth surface 231. When the second ratchet 500 rotates relative to the second tooth ring 220, the first guide tooth surface 331 and the second surface press against each other. The deformation of the second elastic portion 530 causes the second engaging portion 520 to move toward the notch 513 until it disengages from the locking tooth. After passing the locking tooth, the second engaging portion 520 resets under the action of the second elastic portion 530 and engages with the adjacent locking tooth, producing a "click" sound. When force is applied in the opposite direction, the first surface and the second anti-reverse tooth surface 232 interact, preventing relative rotation.

[0074] During the assembly of the packaging container of this application, the transmission rod 120 of the bearing element 100 can first be inserted into the guide element 300 along the limiting hole 311. Then, the transmission rod 120 is engaged with the internal thread 210 of the drive element 200 and rotated downward. Next, the guide element 300 and the drive element 200 are axially fixed. After the extension element 700 is fixed to the guide element 300, the transmission rod 120 is rotated downward to the limit position of the drive element 200, and then the first ratchet 400 is assembled and fixed to the drive element 200. Next, the weight 630 is installed inside the outer bottom 610. Then, the outer bottom 610 is fixedly connected to the second ratchet 500. Next, the inner bottom 620 is fixed to the outer bottom 610. Then, it is assembled with the middle core. Finally, it can be fastened to the cap 800 after cosmetic filling.

[0075] In practical use, the drive base 600 rotates relative to the extension element 700 in the second direction. At this time, the first ratchet 400 is allowed to rotate, and the second meshing part of the second ratchet 500 interacts with the second anti-reverse tooth surface 232 to restrict the rotation (the bottom of the middle core and the base 600 remain stationary in the circumferential direction). Therefore, the drive element 200 can rotate relative to the guide element 300, the bearing element 100 moves axially towards the top, and the paste is screwed out.

[0076] When the drive base 600 rotates relative to the extension element 700 in the first direction, the first engagement part 420 of the first ratchet 400 interacts with the first anti-reverse tooth surface 332 to restrict the rotation (the drive element 200 and the guide element 300 remain circumferentially stationary), while the second ratchet 500 allows rotation. Therefore, the bottom of the middle core can rotate relative to the base 600, while the axial position of the bearing element 100 remains stationary, and the length of the paste that is twisted out also remains unchanged.

[0077] 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.

[0078] 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.
