Detailed Implementation
[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations.
[0037] Example 1:
[0038] This embodiment discloses a quantitative liquid dispensing press pen, such as... Figure 1 As shown, it includes a pen barrel 1, a pen cap 2, and a press-and-push assembly 3.
[0039] like Figure 3 As shown, the pen barrel 1 has a receiving cavity 11 at the front for holding cosmetics. The receiving cavity 11 has an opening 12 at its front end and a piston 13 at its rear. A pressing and pushing component 3 is located at the rear of the pen barrel 1 to push the piston 13 to move. A dispensing head 4 is located at the opening 12. The receiving cavity 11 is used to store cosmetics. The opening 12 is the outlet and inlet for the cosmetics. The dispensing head 4 can be removed from the opening 12 before use. Because the opening 12 has a large diameter, it is convenient to pour cosmetics into the receiving cavity 11. The dispensing head 4 guides the cosmetics to flow out smoothly and disperses the cosmetics evenly. The piston 13 moves within the receiving cavity 11, and driven by the pressing and pushing component 3, the cosmetics are squeezed out from the opening 12.
[0040] like Figure 2 and Figure 3 As shown, the pen barrel 1 has limiting grooves 14 on both sides, and the pressing and pushing assembly 3 has a slider 31. The slider 31 slides within the limiting grooves 14, and by limiting the distance that the pressing and pushing assembly 3 pushes the piston 13, a quantitative dispensing of liquid is achieved. The limiting grooves 14 and the slider 31 ensure the stability of the movement trajectory of the pressing and pushing assembly 3. By limiting the sliding distance of the slider 31, the movement distance of the piston 13 can be precisely controlled, thereby achieving a quantitative dispensing of cosmetics and avoiding waste.
[0041] like Figure 2 , Figure 6 and Figure 7 As shown, the pressing and pushing assembly 3 includes a tail cap 32, a transmission component 33, and a driven component 34; the tail cap 32 is sleeved on the end of the transmission component 33, and the transmission component 33 and the driven component 34 are respectively provided with a first locking connector 35 and a second locking connector 36, and the ends of the first locking connector 35 and the second locking connector 36 are provided with mutually cooperating locking teeth 37.
[0042] like Figure 6As shown, the driven member 34 has a push rod 38 at one end, and a fixing member 15 is provided inside the pen barrel 1. The push rod 38 passes through the center of the fixing member 15 and is fixedly connected to the piston 13 at its end. The slider 31 is provided on the push rod 38. A return spring 39 is provided on the push rod 38, and the two ends of the return spring 39 are respectively pressed against the fixing member 15 and the second snap-fit connector 36.
[0043] like Figure 4 , Figure 5 and Figure 8 As shown, the first card connector 35 is provided with a guide block 351, and the pen barrel 1 is provided with a guide groove 16. The guide groove 16 is set with long and short grooves. The guide block 351 and the guide groove 16 are staggered in their cooperation with the first card connector 35 and the second card connector 36.
[0044] like Figure 9 As shown, the dispensing head 4 has an insertion part 41 at the bottom that mates with the opening 12, baffles 42 on both sides, and a dispensing core 43 at the front end; the insertion part 41 has a through hole. The insertion part 41 can be inserted into the opening 12 to ensure that the dispensing head 4 is securely installed and well-sealed. The baffles 42 are used to limit the flow and prevent cosmetics from spilling during dispensing. The dispensing core 43 is made of a porous material, which allows for smooth dispensing and even distribution of cosmetics, enabling the product to be smoothly applied to the skin.
[0045] The opening 12 has a threaded part 17 on the outside and an internal thread on the inside of the pen cap 2. The pen cap 2 is detachably connected to the front end of the pen barrel 1 through the threaded part 17.
[0046] like Figure 10 As shown, the end cap 32 has a protrusion 321, and the end of the pen barrel 1 has a retaining ring 18. The inner diameter of the retaining ring 18 is smaller than the outer diameter of the protrusion 321, which is used to prevent the end cap 32 from coming off the end of the pen barrel 1.
[0047] The pen barrel 1 is made of transparent or semi-transparent material, allowing users to visually observe the remaining amount of cosmetics in the container 11, making it convenient to replenish or replace them in a timely manner.
[0048] In actual use, when a user needs to use cosmetics, they simply press the cap 32. The transmission component 33 will drive the first locking connector 35 forward. Through the engagement of the locking teeth 37, the second locking connector 36 and the driven component 34 will move forward together, thereby driving the push rod 38 to move. The movement of the push rod 38 will drive the piston 13 forward, precisely and quantitatively squeezing the cosmetics in the receiving cavity 11 through the opening 12 and the dispensing core 43 of the dispensing head 4. The user can then take an appropriate amount of cosmetics for application. After use, under the action of the return spring 39, the components of the pressing and pushing assembly 3 will automatically return to their initial positions for convenient use next time.
[0049] When cosmetics need to be replenished, first unscrew the pen cap 2, then remove the dispensing head 4 from the opening 12. At this time, the receiving cavity 11 is fully exposed, and the user can easily and quickly fill the receiving cavity 11 with cosmetics. After filling, reinstall the dispensing head 4 into the opening 12 and screw the pen cap 2 back on. The operation is simple and convenient, which helps to improve the reuse rate of the product and reduce the cost of use.
[0050] In addition, the cooperation between the limiting grooves 14 on both sides of the pen barrel 1 and the slider 31 not only ensures the stability of the pressing and pushing component 3 during the movement, but also precisely limits the movement distance of the piston 13, thereby realizing the precise quantitative dispensing of cosmetics.
[0051] In summary, the quantitative dispensing press pen provided by this utility model has the advantages of simple and reasonable structure, accurate and controllable dispensing, good sealing, and ease of use and replenishment. It can effectively meet consumers' demand for high-quality cosmetic packaging and has broad application prospects in the field of cosmetic packaging.
[0052] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
