Description

Technical Field

[0001] The utility model relates to a packaging bottle, in particular to a packaging bottle with a replaceable inner liner. Background Art

[0002] At present, people pay more and more attention to their appearance, especially women, who often need to put on makeup when going out, or touch up their makeup on the way. The cosmetics packaging bottle is a container for storing cosmetics. The cosmetics on the market are single-layer bottles, that is, the cosmetics are directly placed in the outer shell, which is suitable for cosmetics with low storage requirements. However, most cosmetic bottles are double-layer bottles, including an outer shell and an inner liner. The outer shell and the inner liner are often inconvenient to disassemble or cannot be disassembled. When the user finishes using the cosmetics, they can only connect the outer shell packaging and throw it away together. In order to ensure its transportation and storage needs, the external packaging is often made of more expensive materials with a longer service life. Throwing it away directly not only causes waste of materials, but also pollutes the environment due to its difficult-to-degrade characteristics. Therefore, it is urgent to propose a packaging bottle with a replaceable inner liner. Utility Model Content

[0005] The limiting platform is distributed on the top of the movable groove, and the limiting platform and the side wall of the movable groove are left empty to form an air avoidance area.

[0006] The cross-sectional width of the rotating plate is smaller than the cross-sectional width of the air avoidance zone.

[0007] The locking platform is distributed below the limiting platform.

[0008] A baffle is bent outwardly from the top of the inner container, and rotating plates are distributed on both sides below the baffle; the baffle is clamped on the top of the outer shell.

[0009] The beneficial effects of the utility model are as follows: 1. The structure is simple, the production cost is low, and the market competitiveness is improved. 2. The inner liner is easy and convenient to screw in, with low difficulty and high efficiency, and the connection of the inner liner is firm and stable. 3. The inner liner can be effectively replaced, thereby saving the cost of the packaging bottle, which conforms to the modern concept of environmental protection and energy saving. Users can replace the inner liner at any time according to the skin condition and needs at different periods, and choose more suitable cosmetics for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described in detail below with reference to the accompanying drawings. A packaging bottle with a replaceable liner, comprising an outer shell 1, an inner liner 2 embedded in the inner shell 1, the upper part of the inner liner 2 is bent downward to form a rotating plate 21, a space is left between the rotating plate 21 and the inner liner 2 to form an installation area 3, and the outer shell 1 is clamped in the installation area 3, characterized in that: the rotating plate 21 and the outer shell 1 are connected and installed by a screw-in structure 4, the screw-in structure 4 comprises a guide platform 41 provided on the inner wall of the protruding rotating plate 21, and an active groove 42 provided on the outer wall of the recessed outer shell 1, the guide platform 41 is buckled into the active groove 42, and is clamped under the limit platform 5 of the active groove 42; a locking groove 7 is formed through the guide platform 41, and the locking groove 7 clamps the locking platform 6 of the active groove 42 therein, so as to realize the rapid screw-in locking of the inner liner 2.

[0017] The limiting platform 5 is distributed on the top of the movable groove 42, and the limiting platform 5 and the side wall of the movable groove 42 are left empty to form an escape zone.

[0018] The cross-sectional width of the rotating plate 21 is smaller than the cross-sectional width of the air avoidance area.

[0019] The locking platform 6 is distributed below the limiting platform 5 .

[0020] A baffle 8 is bent and extended outward from the top of the inner container 2 , and the rotating plates 21 are distributed on both sides below the baffle 8 ; the baffle 8 is clamped on the top of the outer shell 1 .

[0021] Working principle: Different from the traditional non-detachable structure of the inner liner, the inner liner and the outer shell in this case are connected and installed by a screw-in structure. The screw-in structure includes a guide table set on the inner wall of the rotating plate protruding the inner liner, and a movable groove set on the outer wall of the outer shell. When the rotating plate extends into the movable groove, the guide table rotates along the movable groove until the guide table is clamped under the limit table of the movable groove. The setting of the limit table limits the axial movement of the inner liner.

[0022] In order to further lock the inner liner, a locking groove is formed through the guide platform. During the rotation of the rotating plate, the locking groove can clamp the locking platform in the movable groove therein, thereby achieving limited locking of the inner liner in the lateral direction.

[0023] In order to facilitate the disassembly and installation of the inner liner, the limit platform is distributed at the top of the movable groove. The limit platform and the side wall of the movable groove are left empty to form an avoidance area. At the same time, the cross-sectional width of the avoidance area is smaller than the cross-sectional width of the rotating plate of the inner liner. Therefore, the rotating plate of the inner liner can be easily disassembled and assembled through the avoidance area.

[0024] The inner liner and the outer shell are detachably connected, and the screw-in structure is simple, the manufacturing cost is low, the screw-in operation is simple and convenient, the difficulty is low, and the efficiency is high. At the same time, there are multi-directional limit locks, and the connection of the inner liner is stable and firm. In addition, the inner liner can be effectively replaced, thereby saving the cost of packaging bottles. When the product in the inner liner is used up, it can be replaced with a refill, which is in line with the modern concept of environmental protection and energy saving. Users can also replace the inner liner at any time according to the skin condition and needs at different periods, and choose more suitable cosmetics to use, so it can be widely promoted.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
