Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic bottle caps, in particular to a rotary snap-type cosmetic bottle cap. Background Art

[0002] A cosmetic bottle is a packaging container for carrying the physical form of cosmetics. It not only ensures the safety and stability of the product but also reflects the brand image and product quality. After the cosmetic is filled with the internal liquid, it can be sealed by the end bottle cap, so as to be able to encapsulate the internal liquid of the cosmetic.

[0003] However, most of the existing cosmetic bottle caps are opened by means of threads or end snap-on methods. When there is a large amount of liquid in the soft bottle body and the end snap-on method is used to open and squeeze the liquid, a large amount of liquid is likely to seep into the bottle cap and the bottleneck, which cannot be cleaned, resulting in oxidation and deterioration of the cosmetic at the bottleneck. When there is less liquid in the bottle body and the bottle cap is opened by threads to squeeze the liquid in the soft bottle body, the operation of rotating the threads for multiple circles to disassemble and assemble the bottle cap is cumbersome, so there are certain problems in the use of the cosmetic bottle cap during the opening of the service life, affecting the experience. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rotary snap-type cosmetic bottle cap, which can be conveniently operated when opening the bottle cap during the service life of a soft cosmetic bottle body, improving the use experience.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a rotary snap-type cosmetic bottle cap, including a bottle body and a bottle cap. On the inner wall of the bottle cap near the bottom circumference, positioning blocks are integrally formed at equal intervals. On one side of the top of the bottle cap, an end cover is hinged. On the top of the bottle body, a bottleneck is integrally formed. On the outer circumference of the bottleneck, wedge-shaped guide blocks are integrally formed at equal intervals. On the top of the bottleneck, an elastic corrugated section is integrally formed.

[0006] Preferably, anti-slip patterns are provided on the outer circumferential surface of the bottle cap.

[0007] Preferably, the wedge-shaped guide block is an L-shaped structure, and an arc chamfer matching the positioning block is provided at the top corner of the wedge-shaped guide block. The positioning blocks on the inner circumference of the bottle cap are slidably engaged in the chamfers at the corners of the corresponding wedge-shaped guide blocks.

[0008] Preferably, a sealing block is integrally formed in the middle of the bottom surface of the end cover, and a bottle mouth is integrally formed on the top of the elastic corrugated section.

[0009] Preferably, the sealing block on the bottom surface of the end cover and the bottle mouth on the top of the elastic corrugated section are mutually clamped.

[0010] Preferably, a convex block is integrally formed on one side of the circumferential surface of the end cover away from the hinge part.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] When there is a large amount of cosmetic aqueous solution in the soft bottle body of the present utility model, the sealing block at the bottom of the end cap can be separated from the bottle mouth at the top of the elastic corrugated section and opened. The elastic corrugated section can extend out from the opening of the end cap, so that the elastic corrugated section can be squeezed, and the internal cosmetic aqueous solution overflows from the bottle mouth. In this way, when there is a large amount of cosmetic aqueous solution in the bottle body, it can be used by gently squeezing the relatively small amount of cosmetic aqueous solution remaining in the elastic corrugated section, avoiding the problem of a large amount of cosmetic aqueous solution being squeezed out during the early use when there is a large amount of cosmetic aqueous solution in the bottle body. At the same time, the elastic corrugated section can extend out from the top opening of the end cap, preventing excess cosmetic aqueous solution from entering the bottleneck, where it cannot be cleaned, resulting in deterioration and affecting the use experience.

[0013] In the present utility model, the bottle cap can be rotationally locked into the arc chamfer of the wedge-shaped guide block outside the bottleneck by the positioning block for one full turn. In this way, when opening the bottle cap and squeezing and using the remaining cosmetic aqueous solution in the bottle body, the positioning block can be disengaged from the arc chamfer at the corner of the wedge-shaped guide block by turning the bottle cap forcefully for one full turn, making it faster and more convenient to open the bottle cap.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a rotary snap-type cosmetic bottle cap, including a bottle body 1 and a bottle cap 2. On the inner wall of the bottle cap 2 near the bottom circumference, positioning blocks 22 are integrally formed at equal intervals by die pressing. One side of the top of the bottle cap 2 is hinged with an end cap 3;

[0021] At the top of the bottle body 1, a bottleneck 4 is integrally formed by die pressing. On the outer circumference of the bottleneck 4, wedge-shaped guide blocks 41 are integrally formed at equal intervals by die pressing. At the top of the bottleneck 4, an elastic corrugated section 5 is integrally formed by die pressing;

[0022] When there is a large amount of cosmetic liquid in the soft bottle body 1, the end cap 3 can be opened by separating the sealing block 31 at the bottom of the end cap 3 from the top of the elastic corrugated section 5. The elastic corrugated section 5 can extend out from the opening of the end cap 3. Thus, the elastic corrugated section 5 can be squeezed, so that the internal cosmetic liquid overflows from the bottle mouth 51. In this way, when there is a large amount of cosmetic liquid in the bottle body 1, the less cosmetic liquid remaining in the elastic corrugated section 5 can be used by gently squeezing, avoiding the problem that a large amount of cosmetic liquid overflows during the initial use when there is a large amount of cosmetic liquid in the bottle body 1. At the same time, the elastic corrugated section 5 can extend out from the top opening of the end cap 3, avoiding the entry of excess cosmetic liquid into the bottleneck 4, which cannot be cleaned and causes deterioration, affecting the use experience;

[0023] The bottle cap 2 can be rotationally snapped into the arc chamfer of the wedge-shaped guide block 41 outside the bottleneck 4 by the positioning block 22 rotating one circle and clamped and fixed. In this way, when opening the bottle cap 2 and squeezing and using the remaining cosmetic liquid in the bottle body 1, the positioning block 22 can be disengaged from the arc chamfer at the corner of the wedge-shaped guide block 41 by turning the bottle cap 2 forcefully for one circle, making it faster and more convenient to open the bottle cap 2.

[0024] Among them, anti-slip patterns 21 are provided on the outer circumference of the bottle cap 2. By turning the bottle cap 2, the wedge-shaped guide block 41 is an L-shaped structure, and an arc chamfer matching the positioning block 22 is provided at the top corner of the wedge-shaped guide block 41. The positioning block 22 on the inner circumference of the bottle cap 2 is slidably engaged in the chamfer at the corresponding corner of the wedge-shaped guide block 41. The anti-slip patterns 21 prevent slipping when applying force. In this way, the positioning block 22 can be disengaged from the arc chamfer at the corner of the wedge-shaped guide block 41 by turning the bottle cap 2 forcefully for one circle, making it faster and more convenient to open the bottle cap 2.

[0025] Among them, a sealing block 31 is integrally formed by die pressing in the middle of the bottom surface of the end cap 3, and a bottle mouth 51 is integrally formed by die pressing at the top of the elastic corrugated section 5. The sealing block 31 on the bottom surface of the end cap 3 is engaged with the bottle mouth 51 at the top of the elastic corrugated section 5. A convex block 32 is integrally formed by die pressing on one side of the circumferential surface of the end cap 3 away from the hinge part. By separating the sealing block 31 at the bottom of the end cap 3 from the bottle mouth 51 at the top of the elastic corrugated section 5 and opening it, the elastic corrugated section 5 can extend out from the opening of the end cap 3. Thus, the elastic corrugated section 5 can be squeezed, so that the internal cosmetic liquid overflows from the bottle mouth 51. In this way, when there is more cosmetic liquid in the bottle body 1, the less cosmetic liquid remaining in the elastic corrugated section 5 can be gently squeezed for use, avoiding the problem that when there is more cosmetic liquid in the bottle body 1, more cosmetic liquid overflows during the initial use. At the same time, the elastic corrugated section 5 can extend out from the top opening of the end cap 3, preventing excess cosmetic liquid from entering the bottleneck 4 and being unable to be cleaned up.

[0026] Working principle: During use, when there is more cosmetic liquid in the soft bottle body 1, the sealing block 31 at the bottom of the end cap 3 can be separated from the bottle mouth 51 at the top of the elastic corrugated section 5 and opened. The elastic corrugated section 5 can extend out from the opening of the end cap 3. Thus, the elastic corrugated section 5 can be squeezed, so that the internal cosmetic liquid overflows from the bottle mouth 51. In this way, when there is more cosmetic liquid in the bottle body 1, the less cosmetic liquid remaining in the elastic corrugated section 5 can be gently squeezed for use, avoiding the problem that when there is more cosmetic liquid in the bottle body 1, more cosmetic liquid overflows during the initial use. At the same time, the elastic corrugated section 5 can extend out from the top opening of the end cap 3, preventing excess cosmetic liquid from entering the bottleneck 4 and being unable to be cleaned up, resulting in deterioration and affecting the use experience.

[0027] After use, the elastic corrugated section 5 can be released, so that the internal cosmetic liquid drops down into the bottle body 1 by gravity. In this way, by pressing down the end cap 3, the elastic corrugated section 5 can be restored inside the bottle cap 2. After being compressed, it can be fixed by the engagement of the bottle mouth 51 at the top and the sealing block 31.

[0028] When there is not much cosmetic liquid left in the bottle body 1, the bottle cap 2 can be rotated one circle through the positioning block 22 and snapped into the arc chamfer of the wedge-shaped guide block 41 outside the bottleneck 4 for fixing. In this way, when opening the bottle cap 2 and squeezing and using the remaining cosmetic liquid in the bottle body 1, the positioning block 22 can be disengaged from the arc chamfer at the corner of the wedge-shaped guide block 41 by twisting the bottle cap 2 forcefully for one circle, making it faster and more convenient to open the bottle cap 2.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes and modifications can be made to these embodiments without departing from the principle of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
