Abstract
Description
Technical Field
[0001] This application relates to the field of cosmetic packaging, and in particular to a lid for a cosmetic packaging container and a cosmetic packaging container. Background Technology
[0002] As consumers demand higher levels of hydration from cosmetics, existing lipsticks are gradually becoming liquid, which in turn places higher demands on the airtightness of cosmetic packaging tubes.
[0003] Currently, the overall airtightness of cosmetic packaging tubes on the market is poor, which can lead to serious loss of cosmetic product. Furthermore, when cosmetic packaging tubes are made of plastic, the small molecules in the lipstick product have smaller gaps than the molecules in the plastic component. These small molecules can easily penetrate the plastic component and be discharged outside the lipstick tube, exacerbating the loss of cosmetic product. Therefore, there is an urgent need to improve cosmetic packaging tubes. Utility Model Content

[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] See Figures 1-2 One embodiment of this application provides a cosmetic packaging container, including a base 200, a storage component 300 whose bottom is inserted into the base 200 and has an opening at the top, and a cover 100 that cooperates with the base 200 and surrounds the storage component 300. The storage component 300 can employ existing technology; for example, the storage component 300 includes a storage element, a guiding element, a driving element, and a decorative element. The storage element includes a cylindrical body for holding cosmetics and a transmission rod connecting the cylindrical body, wherein the cosmetics refer to cream-like cosmetics such as lipsticks and lip glosses. The driving element has a tubular structure, and its inner wall is provided with a spiral groove that cooperates with the transmission rod to drive the storage element. The guiding element is rotatably engaged with the driving element, restricting the rotation of the storage element when the driving element rotates relative to it. The decorative element is fixedly threaded onto the guiding element.
[0041] See Figures 1-5 This application pertains to a cap 100 for a cosmetic packaging container. The cap 100 includes a first metal cylinder 110 (metal is chosen because of its superior sealing performance) that is closed at the top and open at the bottom. An annular groove 111 is formed by recesses in the inner wall of the first metal cylinder 110, and a sealing ring 113 is fitted within the annular groove 111. Of course, to further improve sealing performance, the number of annular grooves 111 can be adaptively selected according to requirements, for example, see [reference needed]. Figure 5 In the axial direction, there are two annular grooves 111, and each annular groove 111 is equipped with a sealing ring 113.
[0042] To enhance the overall aesthetics of the cosmetic packaging container, the cap 100 of this application further includes a first outer shell 120, with a first metal cylinder 110 concealed and fixed within the first outer shell 120 (forming a sandwich between the two). Furthermore, both the first outer shell 120 and the first metal cylinder 110 are formed from metal sheets, preferably with a thickness of 0.30mm to 0.45mm. The first metal cylinder 110 undergoes partial deformation to form an annular groove 111 on its inner wall, and correspondingly, a convex ring 112 is formed on its outer wall near the inner wall of the first outer shell 120 (the sandwich accommodates the convex ring 112). The cross-sectional shape of the convex ring 112 can be adapted to meet specific requirements; this application does not impose special requirements, for example, see [reference needed]. Figure 4 Four embodiments are shown. In this embodiment, considering that the sealing ring 113 needs to cooperate with the base 200, the annular groove 111 is set near the bottom of the first metal cylinder 110 for easy cooperation.
[0043] When the cosmetic packaging container is not in use, the top opening of the storage component 300 extends into the first metal cylinder 110, and the sealing ring 113 engages with the base 200 to isolate the opening from the atmosphere. Because the sealing ring 113 provides a strong seal when engaged with the base 200, there is a possibility that the base 200 may pop out.
[0044] Therefore, to overcome this problem, the cover 100 of this application further includes a locking member 130 disposed at the opening of the first outer shell 120, wherein the locking member 130 has a ring-shaped structure and is clamped between the first outer shell 120 and the first metal cylinder 110 (located within the interlayer). One end of the locking member 130 is close to the bottom of the first outer shell 120, and the other end extends to the protruding ring 112.
[0045] See Figure 3 In this embodiment, the bottom of the first outer shell 120 extends downward relative to the bottom of the first metal cylinder 110, and the engaging member 130 is partially exposed outside the first metal cylinder 110. At this location, an annular groove 131 is provided on the inner wall of the engaging member 130. Preferably, the thickness of the engaging member 130 is greater than the thickness of the first metal cylinder 110 / first outer shell 120, and the thickness ratio is 1.5~2.6:1.
[0046] See Figure 1 as well as Figures 6-7 The base 200 of this application includes a second metal cylinder 210 that is closed at the bottom and open at the top, and a sealing ring 113 is sealed to the second metal cylinder 210. Accordingly, the second metal cylinder 210 is formed from sheet metal, the thickness of which is preferably 0.30mm to 0.45mm. Its top opening has an inwardly turned edge 211, which prevents the opening from being too sharp, so as to avoid cutting the sealing ring 113 when it is fitted with the first metal cylinder 110, thus preventing problems that affect airtightness.
[0047] Of course, other methods can also be used to prevent the top opening of the second metal cylinder 210 from being too sharp, for example, see Figure 7 In options b and c, a chamfer can be directly provided on the outer peripheral wall of the top of the second metal cylinder 210 (option c), or the top of the second metal cylinder 210 can be tilted inward and contracted, and a transition slope can be provided on the outer wall (option b) to avoid the sealing ring 113.
[0048] Further, see Figure 8 The base 200 also includes a second outer shell 220, with the second metal cylinder 210 partially inserted into and partially exposed. Specifically, the second outer shell 220 has a tapered snap-fit portion 221 for inserting into the second outer shell 220 and engaging with the engaging member 130. In this embodiment, the snap-fit portion 221 is provided with a plurality of circumferentially evenly arranged protrusions 222, which engage with the annular groove 131 to achieve axial positioning of the second outer shell 220 and the cover 100. Considering the overall aesthetics, the outer surfaces of the first outer shell 120 and the second outer shell 220 are flush. Preferably, the second outer shell 220 is also made of sheet metal, which not only improves the sealing performance but also facilitates recycling.
[0049] In one embodiment, see Figures 1-2 as well as Figure 6 The second metal cylinder 210 has an anti-detachment structure and an anti-rotation structure for connecting the storage component 300. The anti-detachment structure includes an anti-detachment part 212 disposed within the second metal cylinder 210. Correspondingly, a corresponding annular part 310 is disposed on the outer periphery of the storage component 300, and the annular part 310 abuts against the bottom of the anti-detachment part 212 (specifically, the anti-detachment part 212 in this application is an inwardly protruding annular structure) to restrict axial movement of both. The anti-rotation structure includes a positioning groove 213 disposed on the inner wall of the second metal cylinder 210 and arranged axially. Correspondingly, a positioning key 320 is disposed on the storage component 300 that cooperates with the positioning groove 213. The positioning key 320 and the positioning groove 213 cooperate to achieve circumferential positioning of both.
[0050] The packaging container of this application can be assembled in the following steps. For example, the base 200 and the storage component 300 can be assembled first. Specifically, glue is applied to the inner wall of the second outer shell 220, and the second metal cylinder 210 is installed into the second outer shell 220 by a pneumatic platform. Then, the second metal cylinder 210 and the storage component 300 are assembled and fixed.
[0051] Next, assemble the cover 100. Specifically, use a jig to insert the sealing ring 113 into the annular groove 111 of the first metal cylinder 110, then fit the locking piece 130, apply glue to the inside of the first outer shell 120, insert the first metal cylinder 110 that mates with the locking piece 130, and press it into place using a pneumatic press. Finally, fasten the assembled cover 100 and base 200 together to complete the assembly of the packaging container.
[0052] The lid and the cosmetic packaging container of this application have at least one of the following technical effects:
[0053] 1. The sealing ring is located inside the cover, making the overall design more aesthetically pleasing;
[0054] 2. The lid and base are made of metal, which has a good sealing effect and can prevent cosmetic molecules from penetrating the surface and being lost, so as to maintain the moisturizing effect of the cosmetic.
[0055] 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.
[0056] 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.
