Description

Technical Field

[0001] This utility model relates to the field of cosmetic container technology, and in particular to a pen-shaped cosmetic dropper. Background Technology

[0002] Serums are mostly watery and contain abundant nutrients, making them ideal for bacterial growth. Therefore, cosmetic containers for serums are usually equipped with pumps or droppers. Pressing the pump to dispense the serum or using a dropper to draw it up can reduce the serum's contact with the outside world and effectively reduce product contamination.

[0003] However, pump heads have a complex structure and are difficult to install, and their production costs are high; while dropper containers are open when users draw up the essence, making it easy for the essence inside to come into contact with the outside environment and cause product contamination.

[0004] To address these technical problems, a pen-shaped cosmetic dropper is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pen-shaped cosmetic dropper that is easy to carry, reduces the contact between the liquid inside the container and the outside environment, and is low in cost.

[0006] The technical solution adopted by this utility model to solve the problem is as follows: a pen-shaped cosmetic dropper, comprising a main body, a receiving cavity provided inside the main body, a piston provided inside the receiving cavity, the piston dividing the receiving cavity into a first chamber for holding cosmetics and a second chamber for holding air, a dropper head communicating with the first chamber provided at the top of the main body, and a ring-shaped bottom cover provided at the bottom of the main body; it also includes a rubber head, the bottom cover being fitted onto the rubber head, the upper part of the rubber head abutting against the inner wall of the second chamber and forming a seal, the lower part of the rubber head passing through the bottom cover and extending to the outside of the main body; a pusher head is slidably connected to the bottom cover, the pusher head being located at the bottom of the rubber head, and both the rubber head and the pusher head are provided with through holes, the through holes communicating with the second chamber and the outside.

[0007] As a further improvement to the above technical solution, the dripper head is provided with a top cover, and a plug is provided on the inner side of the top cover, the plug sealing the liquid outlet of the dripper head.

[0008] As a further improvement to the above technical solution, the dripper head is integrally formed with the main body, the top cover is provided with an internal thread, the dripper head is provided with an external thread, and the top cover is screwed to the dripper head.

[0009] As a further improvement to the above technical solution, the drip head is detachably connected to the top of the main body, the upper part of the main body is provided with external threads, the top cover is provided with internal threads, and the top cover is screwed to the main body.

[0010] As a further improvement to the above technical solution, a downward-opening snap-fit ​​groove is provided around the top of the rubber head, and a snap-fit ​​claw is provided around the top of the bottom cover, the snap-fit ​​claw engaging with the snap-fit ​​groove.

[0011] As a further improvement to the above technical solution, a groove is provided around the inner wall of the main body, and a protrusion is provided around the outer wall of the bottom cover, the protrusion being engaged with the groove.

[0012] As a further improvement to the above technical solution, a boss extends inward around the bottom edge of the bottom cover, and a flange is provided outward around the top of the push head, the flange overlapping the boss.

[0013] As a further improvement to the above technical solution, the main body is made of PP and the rubber head is made of TPE.

[0014] As a further improvement to the above technical solution, the piston is made of PE.

[0015] The beneficial effects of this utility model are as follows: Before filling the dropper, the dropper head or bottom cap can be pre-installed. The dropper can be filled with solution either upright or upside down. The installation steps are simple. When in use, by pressing the pusher, the pusher squeezes the rubber head, thereby driving the outside air into the second chamber through the through hole, increasing the air pressure in the second chamber, thereby pushing the piston to move, so that the piston can push the solution in the first chamber to flow out to the dropper head. The user can control the liquid output according to the force and number of times the pusher head is pressed. During use, the liquid in the receiving chamber does not come into contact with air, which can effectively prevent the liquid from deteriorating. The dropper has a simple structure and low production cost. Attached Figure Description
