[0043] The technical solutions of the present utility model will be elaborated in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and features of the present utility model are more easily understood by those skilled in the art. Obviously, the described embodiments of the present application are only a part of the embodiments of the present application, rather than all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.
[0044] The following descriptions regarding orientations such as up, down, left, right, front, back, inside, and outside are all defined with reference to the orientations observed by the user when the cosmetic packaging container is placed normally and the lid of the container inner liner is covered on the box body. The purpose is only to clearly elaborate the relative positional relationship of the cosmetic packaging container.
[0045] Embodiment 1
[0046] See Figures 1 to 3 A cosmetic packaging container as shown, which includes a container inner liner 100 for containing cosmetics, an outer shell 200, and an outer lid 300. Among them, the container inner liner 100 is installed in the outer shell 200, and the outer lid 300 can be cooperatively covered on the outer shell 200. In this embodiment, the outer shell 200 and the outer lid 300 are connected by a hinge, and the cosmetic packaging container can be opened or closed by flipping the outer lid 300. The outer shell 200 and the outer lid 300 protect the container inner liner 100 from being damaged. In some embodiments, the container inner liner 100 is detachably connected to the outer shell 200. When the cosmetics are used up, the container inner liner 100 can be replaced without discarding the entire cosmetic packaging container, thereby realizing the recycling of resources and avoiding waste.
[0047] See Figures 4 to 6A container inner liner 100 as shown includes a box body 1, a box cover 2 and a sealing ring 3. The box cover 2 can be fittingly covered above the box body 1. The box body 1 has a receiving cavity 11 with an upward opening, and cosmetics are contained in the receiving cavity 11. The box body 1 further includes a mounting groove 12 provided circumferentially outside the receiving cavity 11 with an upward opening. The sealing ring 3 is fixedly arranged in the mounting groove 12 and can be sealingly connected with the box cover 2, so as to prevent the cosmetics from leaking out and prevent external objects from entering the receiving cavity 11 to contaminate the cosmetics. The sealing ring 3 has a first ring body 31 and a second ring body 32 fixedly arranged with each other. The first ring body 31 is fixedly inserted into the mounting groove 12, and the first ring body 31 is in sealing contact with the groove wall of the mounting groove 12. At least part of the second ring body 32 is located above the mounting groove 12. The lower part of the box cover 2 has an annular cover ring 23. When the box cover 2 is covered above the box body 1, the second ring body 32 is in sealing contact with the cover ring 23.
[0048] Through the sealing fit between the first ring body 31 and the box body 1, and the sealing fit between the second ring body 32 and the box cover 2, while realizing the connection between the box body 1 and the box cover 2, the sealing between the box body 1 and the box cover 2 is achieved, ensuring that the cosmetics in the receiving cavity 11 will not leak outwards and will not be contaminated.
[0049] In this embodiment, the box cover 2 and the box body 1 are connected by a hinge, and the box cover 2 can be opened and closed by turning the box cover 2 up and down. In other embodiments, the box cover 2 and the box body 1 can be connected by a covering method to realize the connection between the box cover 2 and the box body 1.
[0050] In this embodiment, when the box cover 2 is covered above the box body 1, the cover ring 23 is located inside the circumferential direction of the second ring body 32, and the outer circumferential surface of the cover ring 23 is in sealing contact with the inner circumferential surface of the second ring body 32. In some embodiments, when the box cover 2 is covered above the box body 1, the cover ring 23 is located outside the circumferential direction of the second ring body 32, and the inner circumferential surface of the cover ring 23 is in sealing contact with the outer circumferential surface of the second ring body 32.
[0051] In this embodiment, the second ring body 32 includes a support portion 321 and a sealing portion 322. The sealing portion 322 is fixedly arranged inside the support portion 321, and the hardness of the sealing portion 322 is less than that of the support portion 321. When the box cover 2 is covered above the box body 1, the sealing portion is in sealing contact with the cover ring 23. Since the hardness of the sealing portion 322 is small, it can undergo greater elastic deformation, so as to obtain a better sealing effect.
[0052] In this embodiment, the inner circumferential surface of the sealing portion 322 has a first convex ring 323 that protrudes inward and extends. The first convex ring 323 is provided with one or a plurality of spaced apart in the up and down directions. When the lid 2 is placed on top of the box body 1, the first convex ring 323 abuts against the outer circumferential surface of the lid ring 23, thereby forming a seal. When sealing, along the radial direction of the sealing ring 3, the lid ring 23 presses the sealing portion 322 outward. At this time, the support portion 321 located outside the sealing portion 322 can play a supporting role to limit the outward displacement of the sealing portion 322 and ensure a good sealing effect. In this embodiment, the support portion 321 and the first ring body 31 are made of the same material and are integrally formed, so that the support portion 321 can provide more stable support. In some preferred embodiments, the support portion 321 is also integrally formed with the sealing portion 322. In this way, the first ring body 31 and the second ring body 32 are integrally injection molded, which is simple to prepare.
[0053] In this embodiment, through the cooperation between the first convex ring 323 and the lid ring 23, while realizing the sealing function, the up and down displacement of the lid 2 is restricted by the mutual extrusion between the first convex ring 323 and the lid ring 23, thereby realizing the connection between the lid 2 and the sealing ring 3, and further realizing the connection between the lid 2 and the box body 1. The mutual extrusion between the first convex ring 323 and the lid ring 23 also provides a force to prevent the lid 2 from being opened, thereby avoiding the lid 2 from being accidentally touched and opened, and preventing cosmetics from leaking out.
[0054] In this embodiment, refer to Figure 7 , Figure 8 As shown, the lid 2 includes an upper lid body 21, and the lid ring 23 extends downward from the bottom surface of the upper lid body 21. When the lid 2 is placed on top of the box body 1, the upper lid body 21 is placed on top of the second ring body 32, and the bottom surface of the upper lid body 21 is in sealing contact with the second ring body 32. Specifically, the upper part of the sealing portion 322 has a second convex ring 324 that protrudes upward. The second convex ring 324 is provided with one or a plurality of spaced apart along the radial direction of the sealing ring 3. When the lid 2 is placed on top of the box body 1, the second convex ring 324 abuts against the lower part of the upper lid body 21. The sealing cooperation between the upper lid body 21 and the second ring body 32 further improves the sealing effect of the container inner liner 100.
[0055] Refer to Figure 8 As shown, in this embodiment, the upper part of the sealing portion 322 is provided with one second convex ring 324, and two first convex rings 323 are spaced apart on the inner circumferential surface of the sealing portion 322. When the lid 2 is placed on top of the box body 1, three seals are formed between the lid 2 and the sealing ring 3, which can provide a good sealing effect.
[0056] In this embodiment, there is a gap between the second convex ring 324 and the support portion 321. In this way, during the process of the lid 2 being closed downward, the upper cover body 21 presses the second convex ring 324 downward, and the second convex ring 324 can deform inward along the radial direction of the sealing ring 3, thereby driving the sealing portion 322 to deform inward, causing the first convex ring 323 to tightly squeeze the lid ring 23 inward, and further improving the squeezing effect between the sealing portion 322 and the lid ring 23 and enhancing the sealing performance.
[0057] In this embodiment, the lid 2 further includes a lower cover body 22. The lower cover body 22 extends downward from the upper cover body 21. The lid ring 23 is disposed around the outer side of the lower cover body 22 and is spaced apart from the lower cover body 22. When the lid 2 is placed on top of the box body 1, the lower cover body 22 is received inside the second ring body 32. Since there is a gap between the lid ring 23 and the lower cover body 22 in the radial direction of the lid 2, it provides space for the radial deformation of the lid ring 23, thereby enabling the sealing function to be better achieved.
[0058] In this embodiment, one of the first ring body 31 and the installation groove 12 is provided with an annular first protrusion 121, and the other is provided with an annular second protrusion 311. Refer to Figure 8 As shown, in this embodiment, the first protrusion 121 extends inwardly from the outer sidewall of the installation groove 12, and the second protrusion 311 extends inwardly from the inner circumferential surface of the first ring body 31. The first protrusion 121 tightly abuts against the outer circumferential surface of the first ring body 31, and the second protrusion 311 tightly abuts against the inner sidewall of the installation groove 12, thereby achieving the sealing between the first ring body 31 and the installation groove 12. In some embodiments, there is one first protrusion 121 and one second protrusion 311 respectively. In other embodiments, the first protrusion 121 and the second protrusion 311 respectively include a plurality of spaced apart in the vertical direction. In this embodiment, as shown in Figure 8 As shown, the outer sidewall of the installation groove 12 is provided with one first protrusion 121, and the inner circumferential surface of the first ring body 31 is provided with two second protrusions 311 spaced apart, forming three seals between the groove wall of the installation groove 12 and the first ring body 31.
[0059] In this embodiment, refer to Figure 8 As shown, the sealing ring 3 further includes a third ring body 33. The first ring body 31, the second ring body 32, and the third ring body 33 are fixedly arranged with each other. The third ring body 33 extends from the upper part of the first ring body 31 towards the accommodation cavity 11, and at least a part of the third ring body 33 is blocked above the accommodation cavity 11. In this embodiment, the third ring body 33, the first ring body 31, and the second ring body 32 are integrally formed, and the first ring body 31, the support portion 321, and the third ring body 33 are made of the same material.
[0060] In this embodiment, a sealing structure is provided between the third ring body 33 and the box body 1. Specifically, the third ring body 33 includes a ring main body 331 extending radially along the sealing ring 3 and an abutting portion 332 extending downward from the ring main body 331. The third ring body 33 extends from the installation groove 12 to above the accommodation cavity 11, and the abutting portion 332 extends downward into the accommodation cavity 11. A seal is formed between the abutting portion 332 and the cavity wall of the accommodation cavity 11 to prevent the cosmetics in the accommodation cavity 11 from entering the installation groove 12. In this embodiment, the sealing structure between the third ring body 33 and the box body 1 not only realizes the sealing function but also stably fixes the sealing ring 3 and the box body 1 together.
[0061] Embodiment 2
[0062] See Figure 9 and Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the cover ring 23 extends obliquely outward along the radial direction of the box cover 2 from top to bottom. In this way, during the process of closing the box cover 2, the cover ring 23 will extrude the sealing portion 322 outward, so as to obtain a better tightening effect and thus a better sealing effect. In this embodiment, see Figure 10 As shown, an avoidance groove with an upward opening is provided in the upper part of the first ring body 31. When the box cover 2 is covered on the box body 1, the lower part of the cover ring 23 is inserted into the avoidance groove. At the same time, in this embodiment, only one first convex ring 323 is provided on the inner circumferential surface of the sealing portion 322, and there is no gap between the second convex ring 324 and the supporting portion 321. During the process of the box cover 2 being closed downward, the sealing portion 322 is squeezed between the cover ring 23 and the supporting portion 321.
[0063] Embodiment 3
[0064] See Figure 11 and Figure 12 As shown, the main difference between this embodiment and Embodiment 2 is that in this embodiment, the second ring body 32 is made of the same material, and the hardness of the second ring body 32 is less than that of the first ring body 31, so that it can better undergo elastic deformation and thus obtain a better sealing effect. Specifically, the inner circumferential surface of the second ring body 32 has a third convex ring 325 protruding inward, and the upper part of the second ring body 32 has a fourth convex ring 326 protruding upward. When the box cover 2 is covered on the box body 1, the third convex ring 325 is in sealing contact with the outer circumferential surface of the cover ring 23, and the fourth convex ring 326 is in sealing contact with the lower part of the upper cover body 21.
[0065] See Figure 12 As shown, in this embodiment, two fourth convex rings 326 are provided at intervals on the upper part of the second ring body 32, and a third ring body 325 is provided on the inner circumferential surface of the second ring body 32. When the box cover 2 is covered on the box body 1, three seals are formed between the box cover 2 and the sealing ring 3.
[0066] In this embodiment, a sixth convex ring 231 protruding and extending outward is provided at the lower part of the cover ring 23. When the lid 2 is placed on the upper part of the box body 1, the sixth convex ring 231 is in sealing contact with the inner circumferential surface of the second ring body 32. Specifically, when the lid 2 is placed on the upper part of the box body 1, the third convex ring 325 and the sixth convex ring 231 are arranged in sequence in the up-down direction. Specifically, the third convex ring 325 is located above the sixth convex ring 231. The third convex ring 325 abuts against the outer circumferential surface of the cover ring 23, and the sixth convex ring 231 abuts against the inner circumferential surface of the sealing part 322. Such a setting can not only obtain a better sealing effect, but also provide greater resistance to the relative movement between the cover ring 23 and the second ring body 32, ensuring the firmness of the lid 2 when it is closed.
[0067] Embodiment 4
[0068] See Figure 13 and Figure 14 As shown, the main difference between this embodiment and Embodiment 1 is that in this embodiment, the second ring body 32 is an integral body. The first ring body 31, the second ring body 32 and the third ring body 33 are made of the same material, and the first ring body 31, the second ring body 32 and the third ring body 33 are integrally formed, so the manufacturing of the sealing ring 3 is simple. In this embodiment, when the lid 2 is placed on the upper part of the box body 1, the cover ring 23 is in hard contact with the second ring body 32. See Figure 14 As shown, a seventh convex ring 327 protruding and extending inward is provided on the inner circumferential surface of the second ring body 32. The cover ring 23 extends obliquely outward in the radial direction of the lid 2 from top to bottom at the same time. A sixth convex ring 231 is provided at the lower part of the cover ring 23. When the lid 2 is placed on the upper part of the box body 1, the seventh convex ring 327 abuts against the outer circumferential surface of the cover ring 23, and the sixth convex ring 231 abuts against the inner circumferential surface of the second ring body 32, and the upper part of the second ring body 32 does not form a sealing contact with the upper cover body 21.
[0069] See Figure 14 As shown, in this embodiment, the lid 2 is fixedly provided with an annular snap ring 24. The snap ring 24 is arranged on the inner side of the circumferential direction of the cover ring 23, and the hardness of the snap ring 24 is less than that of the lid 2. When the lid 2 is placed on the upper part of the box body 1, the lower part of the snap ring 24 is in sealing contact with the sealing ring 3. In this embodiment, the snap ring 24 is provided with a fifth convex ring 241. The fifth convex ring 241 protrudes and extends downward from the lower part of the snap ring 24. When the lid 2 is placed on the upper part of the box body 1, the fifth convex ring 241 elastically abuts against the sealing ring 3. Specifically, when the lid 2 is placed on the upper part of the box body 1, the fifth convex ring 241 elastically abuts against the upper part of the third ring body 33, thereby forming a seal. In this embodiment, the snap ring 24 and the lid 2 are integrally injection-molded, which is convenient for manufacturing.
[0070] In this embodiment, the fifth convex rings 241 include two that are arranged at intervals along the radial direction of the box cover 2. A V-shaped groove 242 with an opening away from the box cover is formed between the two fifth convex rings 241. During the process of the box cover 2 closing downward, the two fifth convex rings 241 diverge relatively, which is used to increase the contact area with the sealing ring 3, thereby improving the sealing effect. In this embodiment, an annular groove 333 is provided in the upper part of the third ring body 33. When the box cover 2 is placed above the box body 1, the fifth convex ring 241 is inserted into the annular groove 333, and the fifth convex ring 241 elastically abuts against the groove wall of the annular groove 333.
[0071] The features of the above embodiments can be combined with each other to form new embodiments. The container inner liner 100 of all the above embodiments can be used as an air cushion core, and the cosmetic packaging container with the above container inner liner 100 can be used as a powder compact.
