Technical Field

[0001] The utility model relates to the field of cosmetic containers, and particularly relates to an aluminum can with a replaceable inner liner. Background Art

[0002] With the development of cosmetics, it is necessary to develop various cosmetic containers that can hold cosmetics. Generally, in order to store and use cosmetics in the form of liquid or gel, such as lotion, cream, gel, shampoo, and / or conditioner, containers with simple opening and closing functions have been used in the prior art. Correspondingly, the cosmetics are taken out of the container by using fingers or cosmetic tools such as powder puffs and applied to the skin.

[0003] For example, a replaceable cosmetic can with the publication number of CN220924873U realizes the engagement and cooperation between an inner can and an outer can, and can disassemble and replace the used inner can of cosmetics, thus saving costs.

[0004] However, in the above-mentioned prior patents, the engagement between the inner and outer cans is relatively tight. When disassembling and replacing, manual hard pulling is required. Moreover, the opening diameters of some cans are either large or small, and the palm cannot completely pinch the position where the force needs to be applied, so the disassembly is relatively difficult.

[0005] Therefore, when disassembling the inner can of cosmetics, how to achieve smooth disassembly and avoid the relatively concentrated disassembly force is a technical problem to be solved urgently. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an aluminum can with a replaceable inner liner to solve the above-mentioned deficiencies in the prior art.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figures 1 to 7 The utility model is an aluminum can with a replaceable inner liner 23, comprising: a cover assembly 1 and a bottom assembly 2 for containing cosmetics, wherein the cover assembly 1 comprises an outer cover 11 and an inner cover 12, the two are adhered to each other by a colloid, and an inner thread is arranged on the inner surface of the inner cover 12.

[0036] The bottom assembly 2 includes a bottom tank 21, and an external thread is provided at the opening of the bottom tank 21 to match the internal thread of the inner cover 12, and the two are sealed to form a tank body. A gasket 13 is placed at the opening of the bottom tank 21 to cover the opening, so as to improve the sealing of the cosmetics in the bottom tank 21 and reduce its volatilization.

[0037] A middle sleeve 22 is arranged in the bottom tank 21, and a through hole is arranged at the same axis of the bottom tank 21 and the middle sleeve 22. An inner liner 23 is located in the middle sleeve 22 and clamped therein. A push plug 24 that moves up and down is installed in the through hole. Pressing the push plug 24 forces the inner liner 23 to withdraw from the clamping state, so as to achieve replacement or removal of the inner liner 23.

[0038] As described above, the engagement between the middle sleeve 22 and the inner liner 23 ensures the stability of the inner liner 23 during normal use, and reduces the inner liner 23 from falling out of the middle sleeve 22 due to vibration or inversion. The inner liner 23 can be quickly removed or replaced by pressing the push plug 24, which also improves the convenience of operation.

[0039] The bottom of the bottom tank 21 is provided with a first through hole 211, and a stopper 212 extends inwardly from the first through hole 211. The middle sleeve 22 includes an upper tank 221 body attached to the bottom tank 21, and a lower tube 222 located at the bottom of the upper tank 221 body and having a second through hole 2223.

[0040] The lower tube 222 includes a neck portion 2221 and a flared portion 2222 having a diameter larger than the neck portion 2221 . The bottom end of the flared portion 2222 is inserted into the inner side of the stop portion 212 to position the lower tube 222 .

[0041] The flared portion 2222 of the lower tube 222 is inserted inside the resisting portion 212 to ensure accurate positioning of the middle sleeve 22 and prevent the first through hole 211 and the second through hole 2223 from being not on the same axis, which is not convenient for the subsequent assembly of the push plug 24.

[0042] In addition, a plurality of first protrusions 2211 are annularly distributed on the inner wall of the upper tank 221 body. The first protrusions 2211 are vertically arranged in a long strip shape, and both ends have slope sections 2211a, and the middle is a pressing section 2211b, so as to clamp the inner liner 23.

[0043] When the inner liner 23 is installed, when it slides downward, it first moves along the lower part of the slope section 2211a, and then moves to the upper part. Subsequently, it moves along the pressing section 2211b until the inner liner 23 is assembled. At this time, the assembled inner liner 23 can be firmly clamped. When the inner liner 23 is pushed out, the outer wall of the inner liner 23 first moves along the pressing section 2211b, and then moves from the upper part of the slope section 2211a to its lower part, making the pushing out of the inner liner 23 smoother.

[0044] In some embodiments, an annular rib that arches inward is provided on the inner wall of the middle sleeve 22. A plurality of second protrusions 231 are annularly distributed on the outer wall of the inner liner 23. The second protrusions 231 are horizontally arranged in a long strip shape and are abutted and clamped against the annular rib.

[0045] During installation, only need to press the second protrusion 231 below the annular rib, that is, against the lower end of the annular rib, then the inner liner 23 is installed at this time.

[0046] Among them, a gap is left after the middle sleeve 22 and the inner liner 23 are assembled to facilitate the pushing out of the inner liner 23. The gap between the two can reduce their direct contact or interaction force, thereby reducing the difficulty of pushing out the inner liner 23.

[0047] A third protrusion 242 is provided at the upper end of the push plug 24, which abuts against the inner wall of the neck portion 2221 to ensure that the push plug 24 will not slide freely in the non-operating state, prevent the uneven placement of the tank body, or directly push the inner liner 23 during the placement of the tank body for misoperation, and will not affect the pushing movement of the push plug 24 due to the abutment of the push plug 24 and the neck portion 2221.

[0048] In addition, a sliding space 4 is formed between the flared portion 2222 and the upper surface of the abutting portion 212. A convex ring 241 that mates with the sliding space 4 is provided at the lower end of the push plug 24 to ensure that the push plug 24 has a corresponding sliding stroke. The sliding space 4 allows the push plug 24 to move freely during operation, avoiding jamming. Moreover, the stroke of the push plug 24 is strictly controlled, making the operation of the device more precise, reducing errors. At the same time, the friction between components is reduced, wear is decreased, and rapid operation feedback is achieved.

[0049] In some embodiments, a movable push rod 3 is provided at the bottom of the middle sleeve 22. One end of the push rod 3 abuts against the bottom of the inner container 23, and the other end passes through the wall surface of the flared portion 2222 and is placed at a corresponding position above the convex ring 241. When the convex ring 241 moves upward, it drives the push rod 3 to move upward together and push out the inner container 23. By directly driving the push rod 3 when the convex ring 241 moves upward, the loss of force is reduced, the force required to push out the inner container 23 is smaller, the operation is easier, and the stability of the inner container 23 during the pushing process can be maintained, preventing the inner container 23 from tilting or jamming and improving its smoothness.

[0050] The inner container 23 is made of recyclable materials, such as aluminum, PP, PET, HDPE, PVC, etc., including but not limited to other materials, for easy environmental recycling and to avoid wasting resources.

[0051] A weight 25 is also provided in the tank body, enhancing the overall feel of the tank body and making it more comfortable and textured during use.

[0052] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
