Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging container technology, specifically to a loose powder container with a liftable and replaceable inner liner. Background Technology

[0002] As loose powder is a common cosmetic product, its packaging is crucial for maintaining product quality, hygiene, and user experience. Most loose powder containers on the market today have a fixed structure, mainly consisting of a container, an internal powder puff, and an inner liner or powder compartment containing the loose powder. Users open the lid, use the powder puff to apply the loose powder, and then set their makeup.

[0003] However, traditional powder containers have many inconveniences and drawbacks: First, the powder puff is usually fixed to the lid or placed directly on top of the powder, making it difficult to disassemble for thorough cleaning. Long-term use can lead to the accumulation of bacteria, dead skin cells, and residual cosmetics, posing hygiene risks. Second, once the powder is used up, the entire package is often discarded, resulting in waste and contradicting environmental principles. Third, the fixed inner liner cannot be raised or lowered, making it extremely inconvenient to retrieve powder later in use. Furthermore, the product is prone to leakage during transport due to shaking, causing powder to leak from the gaps between the powder puff and the liner, contaminating items in the bag. Therefore, it is necessary to design a new, retractable powder container with a replaceable inner liner to solve these problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a liftable and replaceable inner liner for powder containers, in order to solve at least one technical problem existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A loose powder container with a liftable and replaceable inner liner includes an upper cover, an inner cover, a powder puff, a sealing mechanism, a liftable inner liner mechanism, and an outer container. The upper cover is detachably connected to the outer container. The inner cover is disposed inside the upper cover and connected to the upper cover. The powder puff is fixed inside the upper cover by the inner cover. The liftable inner liner mechanism is disposed inside the outer container. The liftable inner liner mechanism includes an inner liner, a tray, and an elastic component. The tray is disposed below the inner liner. The elastic component is disposed between the tray and the bottom of the outer container. The inner liner is supported inside the outer container by the elastic component and moves downward when pressure is applied and returns to its original position upward after pressure is released.

[0007] A sealing mechanism is provided above the inner liner, and the sealing mechanism is connected in sequence to the inner cover, the liftable inner liner mechanism and the outer tank.

[0008] Preferably, the sealing mechanism includes a shoulder sleeve, a retaining ring, and a plug. The shoulder sleeve is fixed to the upper part of the inner wall of the outer can. The retaining ring is installed on the outer can, and its top is engaged with the shoulder sleeve to limit the upward limit position of the inner liner. The plug is located at the top opening of the inner liner and is connected to the bottom of the powder puff.

[0009] Preferably, the elastic component is one of a spring or a sheet spring.

[0010] Preferably, the shoulder sleeve is fixed to the upper part of the inner wall of the outer tank, and the retaining ring is engaged with the shoulder sleeve and limits the upper limit position of the inner liner.

[0011] Preferably, the inner liner is a replaceable, independent component whose shape is adapted to the internal shape of the outer can.

[0012] Preferably, the top cover is detachably connected to the outer can by either a thread or a snap fastener.

[0013] Preferably, the inner cover and the upper cover are detachably connected by either threads or snaps.

[0014] Preferably, the powder puff is detachably attached to the top cover by means of Velcro, snaps, or magnetic adsorption.

[0016] Compared with the prior art, the powder container with a liftable and replaceable inner liner provided by this utility model has the following beneficial effects:

[0017] 1. By designing the powder puff as a detachable connection, users can easily remove the powder puff for thorough cleaning or regular replacement, effectively avoiding bacterial growth caused by dirt and grime accumulating in the powder puff, ensuring skin health, and improving the safety and hygiene of use.

[0018] 2. By setting up elastic components, the inner liner achieves intelligent lifting and lowering functions through an elastic support structure provided by either a spring or a sheet spring.

[0019] 3. By setting shoulder sleeves and retaining rings, the lifting stroke of the inner liner is precisely limited, ensuring stable operation.

[0020] 4. By featuring replaceable, independent inner containers, users only need to purchase replacement inner containers when the loose powder inside runs out, eliminating the need to discard the entire container. This not only reduces long-term usage costs for consumers but also significantly reduces waste of materials such as plastic, making it more environmentally friendly. Furthermore, users can easily change inner containers containing different shades or textures of loose powder to meet diverse makeup needs.

[0021] 5. By setting the diameter of the tray to match the inner diameter of the outer tank, the tray can move stably up and down along the inner wall of the outer tank. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Please see the appendix Figure 1-5As shown, this embodiment provides a loose powder container with a liftable replaceable inner liner, including an upper cover 1, an inner cover 2, a powder puff 3, a sealing mechanism 4, a liftable inner liner mechanism 5, and an outer container 6. The upper cover 1 is detachably connected to the outer container 6. The inner cover 2 is disposed inside the upper cover 1 and connected to the upper cover 1. The powder puff 3 is fixed inside the upper cover 1 through the inner cover 2. The liftable inner liner mechanism 5 is disposed inside the outer container 6. The liftable inner liner mechanism 5 includes an inner liner 51, a tray 52, and an elastic component 53. The tray 52 is disposed below the inner liner 51. The elastic component 53 is disposed between the tray 52 and the bottom of the outer container 6. The inner liner 51 is supported inside the outer container 6 by the elastic component 53 and moves downward when pressure is applied and returns to its original position when pressure is released. The elastic component 53 is a spring.

[0031] A sealing mechanism 4 is provided above the inner liner 51, and the sealing mechanism 4 is connected in sequence to the inner cover 2, the liftable inner liner mechanism 5 and the outer tank 6.

[0032] The inner cover 2 and the upper cover 1 are detachably connected by either threads or snap fasteners.

[0033] The powder puff 3 is detachably attached to the top cover 1 by means of Velcro, snaps, or magnetic adsorption.

[0034] In this embodiment, the powder puff 3 is designed to be detachable, allowing users to easily remove it for thorough cleaning or periodic replacement. This effectively prevents bacterial growth caused by dirt and grime accumulating on the powder puff, ensuring skin health and improving safety and hygiene. An elastic component 53, through a spring-supported elastic structure, enables the intelligent lifting function of the inner liner 51.

[0035] In a specific embodiment, such as Figure 1-2 As shown, the sealing mechanism 4 includes a shoulder sleeve 41, a retaining ring 42, and a plug 43. The shoulder sleeve 41 is fixed to the upper part of the inner wall of the outer can 6. The retaining ring 42 is installed on the outer can 6, and its top is engaged with the shoulder sleeve 41, limiting the upper limit position of the inner liner 51. The plug 43 is located at the top opening of the inner liner 51 and is connected to the bottom of the powder puff 3. The shoulder sleeve 41 is fixed to the upper part of the inner wall of the outer can 6, and the retaining ring 42 is engaged with the shoulder sleeve 41 and limits the upper limit position of the inner liner 51.

[0036] In this embodiment, a shoulder sleeve 41 is provided, which is pressed into the top opening of the outer tank 6 and fixed to the upper part of the inner wall of the outer tank 6. Then, a retaining ring 42 is inserted into the annular groove on the inner side of the shoulder sleeve 41. The inner diameter of the retaining ring 42 is smaller than the flange or outer diameter of the top of the inner liner 51, thereby mechanically limiting the upward stroke of the inner liner 51 and the tray 52, preventing them from being ejected from the tank by the elastic component 53, such as a spring. By setting the shoulder sleeve 41 and the retaining ring 42, the lifting stroke of the inner liner 51 is precisely limited, ensuring stable operation.

[0037] In a specific embodiment, such as Figure 1-2 As shown, the inner liner 51 is a replaceable independent component, and its shape is adapted to the internal shape of the outer can 6.

[0038] In this embodiment, a replaceable independent inner container 51 is provided. When the loose powder in the inner container 51 is used up, the user only needs to purchase a replacement inner container 51, without having to discard the entire container. This not only reduces the long-term usage cost for consumers but also significantly reduces the waste of materials such as plastic, making it more environmentally friendly. At the same time, users can also easily replace the inner container 51 with different shades or textures of loose powder according to their makeup needs, meeting diverse requirements.

[0039] In a specific embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the upper cover 1 and the outer can 6 are detachably connected by either a thread or a snap fastener.

[0040] In this embodiment, when the user needs to use the product, he / she can separate the outer can 6 and twist the top cover 1 to separate the top cover assembly from the can body.

[0041] In a specific embodiment, such as Figure 1 As shown, the diameter of the tray 52 is adapted to the inner diameter of the outer tank 6.

[0042] In this embodiment, the diameter of the tray 52 is adapted to the inner diameter of the outer can 6, so that the tray 52 can move stably up and down along the inner wall of the outer can 6.

[0043] like Figure 4-5 As shown, the working principle or process of this utility model is as follows:

[0044] In closed, sealed state: When the upper cover 1 is placed on the outer can 6, the tray 52 and the inner liner 51 are pushed upwards by the spring until the stopper 43 at the top of the inner liner 51 is blocked by the retaining ring 51. At this time, the stopper 43 or opening at the top of the inner liner 51 comes into close contact with the lower surface of the powder puff 3 inside the upper cover 1, forming the first seal. Simultaneously, the powder puff 3 itself has a certain amount of elastic compression, further ensuring the reliability of the seal and effectively preventing leakage of loose powder during transportation and carrying.

[0045] Powder dispensing mode: When the user needs to use the powder, grasp the outer can 6 and twist the top cover 1 to separate the top cover assembly from the can body. When applying loose powder, the user presses the inner container 51 downwards with the powder puff 3. The inner container 51, under pressure, pushes the tray 52 downwards, compressing the spring. The inner container 51 descends, separating the stopper 6 at its top opening from the powder puff 3, exposing the loose powder for even application by the powder puff 3. After releasing the pressure, the spring's restoring force immediately pushes the inner container 51 back to its original position, restoring the seal.

[0046] Powder puff cleaning and replacement: Users can easily remove the powder puff 3 from the top cover 1 by unscrewing or prying open the inner cover 2, and then clean or replace it with a new one, ensuring hygiene during use.

[0047] Inner liner replacement: When the powder in the inner liner 51 is used up, the user only needs to open the top cover 1 and take the old inner liner, along with the tray 51, out of the outer container 6. Then, the new inner liner 51, filled with powder, is installed on the tray 52, and the assembly is put back into the outer container 6 to replace the inner liner. This method is economical and environmentally friendly.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
