Description

TECHNICAL FIELD

The present disclosure relates to the technical field of cosmetics, and more particularly, to a cosmetic container.

BACKGROUND

Liquid cosmetics such as aqueous cosmetics and serums on the market are generally stored in containers. When the cosmetics are in use, a dropper pipette assembly or a straw assembly is used to suck a cosmetic solution from a container, and then the cosmetic solution in the dropper pipette assembly is squeezed to drip onto a cotton pad. A cosmetic container and a dropper pipette assembly in the prior art have the following disadvantages: First, a dropper pipette assembly needs to be extended into the container every time the solution in the container is sucked, resulting in discontinuous use; especially when the solution in a bottle is less than one third, the dropper pipette assembly needs to be inserted obliquely, and the dropper pipette assembly can only suck out the solution at a certain angle with the container, which is inconvenient to operate and will cause more residual solution; second, after the solution is sucked by the dropper, the dropper pipette assembly is squeezed or pressed, the solution in the dropper pipette assembly drips out in a linear shape, and a dripping amount cannot be quantified; third, when not in use, the dropper pipette assembly might be unintentionally squeezed and leak, and thus is not convenient to carry.

SUMMARY

In view of problems existing in the prior art, the present disclosure provides a cosmetic container. The container containing a cosmetic solution is assembled with a dropper nozzle for use. A structure is simple and an operation is convenient. The solution can be quantitatively and slowly dripped out through the dropper nozzle in a water droplet form by pressing a button.

A through-hole 50 for the pressing part 42 to pass through is provided on the bottom lid 5. The bottom lid 5 is provided with a concave position 54 conforming to human engineering mechanics, and the pressing part 42 is perfectly matched in the concave position 54. The button 4 is provided with a third sealing ring 41 matched with an inner surface of the tube 3, and a contact part between the button 4 and the tube 3 is sealed by using the third sealing ring 41, to prevent the solution in the chamber 30 from seeping out of the contact part.
Referring to FIG. 1 to FIG. 3, FIG. 9, and FIG. 10, a fourth sealing ring 52 matched with an outer surface of the tube 3 is provided at the inner side of the bottom lid 5, and a contact part between the bottom lid 5 and the tube 3 is sealed by using the fourth sealing ring 52, to prevent the solution in the chamber 30 from seeping out of the contact part. Two outer snap threads 34 are uniformly distributed outside the tube 3 in the circumferential direction, inner snap threads 51 matched with the outer snap threads 34 are provided at the inner side of the bottom lip 5, six bumps 511 are uniformly distributed at one side of the inner snap threads 51 in the circumferential direction, the outer snap threads 34 are clamped into the inner snap threads 51, and the bumps 511 support the outer snap threads 34 in the circumferential direction, to prevent the bottom lip 5 and the tube 3 from being separated due to force. A fixing line 53 is further provided at the inner side of the bottom lid 5, and is configured to enhance the fixing effects of the bottom lid 5 and the tube 3.

An operating process is as follows:
After the screw cap 1, the dropper nozzle 2, and the tube 3 are assembled, an appropriate amount of cosmetic solution is poured into the chamber 30, and then the button 4 and the bottom lid 5 are assembled. When the container is in use, the pressing part 42 of the button 4 is pressed, so that the cosmetic solution in the chamber 30 can enter the nozzle cavity 20 of the dropper nozzle 2 through the tube hole 31, the nozzle cavity 20 is arranged as a buffer nozzle cavity to reduce inner pressure by temporarily storing the cosmetic solution, and the pressing part 42 of the button 4 is further pressed, so that the solution in the nozzle cavity 20 of the dropper nozzle 2 drips onto the cotton pad through the nozzle orifice 21.
This cosmetic container adopted the above technical solution, the dropper nozzle 2 and the tube 3 are assembled together and communicated with each other, and the solution can enter the dropper nozzle 2 completely and continuously through the tube 3 without needing to tilt the dropper nozzle 2 and the tube 3 by a certain angle, and the dropper nozzle 2 does not need to be extended into the container to suck the solution, which is convenient to operate and will not cause residual solution. When the pressing part 42 of the button 4 is pressed, the solution in the tube 3 can drip out quantitatively and slowly through the nozzle orifice 21 in a water droplet form. On the one hand, the user can well control a dropping amount of the solution to avoid waste; on the other hand, the solution will not splash on the clothes, which helps to improve user experience. When the container is not in use, the nozzle orifice 21 is closed by the screw cap 1, so there will be no leakage even if the pressing part 42 is pressed, thereby the container being convenient to carry.
