Description

Technical Field

[0001] The utility model relates to the technical field of packaging containers, and mainly relates to a square cosmetic packaging bottle with a replaceable inner liner. Background Art

[0002] A cosmetic packaging bottle is a container for storing cosmetics. In the existing market, double-layer packaging bottles are widely used in cosmetic packaging bottles, but their outer bottles and inner liners usually have structures that are not easy to disassemble or cannot be disassembled. When consumers use up the cosmetics in the inner liner, they can only throw away the outer packaging together. The outer packaging is often made of materials with high prices and long service lives, which will cause waste of packaging materials for the outer packaging, increase the purchase cost of consumers, and because some packaging bottles are made of non-environmental protection materials, non-environmental protection materials are difficult to degrade and will pollute the environment if discarded casually. Content of the Utility Model

[0003] The utility model aims to solve the problem that the outer bottle and the inner liner in the prior art are usually not easy to disassemble or cannot be disassembled. For this reason, the purpose of the utility model is to provide a square cosmetic packaging bottle with a replaceable inner liner, which can flexibly disassemble the inner liner from the outer bottle to replace the inner liner, thereby effectively saving costs and conforming to the concept of energy conservation and environmental protection.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

The partition divides the installation groove into two parts. A vertical stop condition is provided above one part of the installation groove. The partition and the stop condition enclose a card slot cavity. An insertion ear extending downward is provided on the outer wall of the top of the inner liner. A first barb is provided on the inner wall of the bottom of the insertion ear, and the first barb can be snapped into the card slot cavity to form a snap-fit.

[0006] Preferably, both side surfaces of the partition are arc surfaces.

[0007] Preferably, a support ring extending downward is provided at the bottom of the inner liner.

[0008] Preferably, the partition and the stop condition are of an integral structure.

[0028] Please refer specifically to Figures 1-5 , a square cosmetic packaging bottle with a replaceable inner container, including an outer bottle 1, an inner container 2 and an end cap 3. A receiving cavity is provided in the outer bottle 1, and the inner container 2 is detachably installed in the receiving cavity. Two mounting grooves 11 are provided on the outer wall of the outer bottle 1 at its bottle mouth. The two mounting grooves 11 are arranged opposite to each other. A vertical partition 12 is provided in the mounting groove 11. The partition 12 divides the mounting groove 11 into two parts. A vertical stop 13 is provided above one part of the mounting groove 11. The partition 12 and the stop 13 are of an integral structure. The partition 12 and the stop 13 enclose a card slot cavity 14. An insertion ear 21 extending downward is provided on the outer wall of the inner container 2 at its top. A first barb 22 is provided on the inner wall of the bottom of the insertion ear 21. The first barb 22 can be snapped into the card slot cavity 14 to form a snap-fit. The partition 12 and the stop 13 limit the first barb 22 and prevent the inner container 2 from moving arbitrarily.

[0029] Further, both side surfaces of the partition member 12 are arc surfaces, and the arc surfaces play a role in smooth transition, facilitating the entry or exit of the first barb 22 into or from the card slot cavity 14.

[0030] Further, a support ring 23 extending downward is provided at the bottom of the inner container 2, and the support ring 23 supports the inner container 2, making the height of the inner container 2 match the height of the accommodation cavity.

[0031] Further, a through hole 31 is provided at the inner top of the end cap 3, a clamping step 32 is provided above the through hole 31, a sealing cover 33 is installed in the through hole 31, a second barb 34 is provided below the sealing cover 33, and the second barb 34 extends into the through hole 31 and is clamped with the clamping step 32.

[0032] In this embodiment, a galvanized layer is attached to the outer surface of the sealing cover 33, making the end cap 3 look more beautiful.

[0033] Further, notches 35 are provided on opposite sides of the clamping step 32, and a plurality of positioning members 36 are provided on opposite sides of the sealing cover 33. The positioning members 36 are installed in the notches 35, and the positioning members 36 play a positioning role and can be aligned with the notches 35 during installation, facilitating the accurate installation and positioning of the sealing cover 33.

[0034] Further, the outer bottle 1 and the end cap 3 are square structural members.

[0035] Further, the outer bottle 1 and the end cap 3 are threadedly connected. A limiting member 15 is provided at the end of the thread of the outer bottle 1. The design of the limiting member 15 terminates the thread, preventing the end cap 3 from being over-tightened, and enabling the outer bottle 1 and the end cap 3 to just form a square structure.

[0036] When the inner container 2 needs to be replaced: The consumer first opens the end cap 3, then holds the inner wall of the inner container 2 and rotates the inner container 2 to screw the first barb 22 out of the card slot cavity 14 into another part of the installation slot 11, takes out the inner container 2, and the insertion ear 21 is separated from the installation slot 11 to complete the disassembly of the inner container 2. Replace with a new inner container 2, insert the insertion ear 21 into the installation slot 11, rotate the inner container 2 in the reverse direction, and screw the first barb 22 into the card slot cavity 14 to complete the replacement of the inner container 2.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
