[0001] The utility model relates to the technical field of cosmetic packaging containers, and particularly to a pressing lip pencil. Background Art

[0002] In the field of cosmetics, lip gloss, as a commonly used beauty product for modern women, not only has the functions of moisturizing and protecting the lips, but also can significantly enhance the beauty of the face. With the continuous progress of technology and the diversification of consumer demands, the packaging design of lip gloss is also constantly innovating. Among them, the lip gloss pressing pen is favored because of its convenient use method. However, the existing lip gloss pressing pens generally adopt the end-pressing method in design, which is particularly inconvenient when the capacity of the lip pencil is large.

[0003] Specifically, when the capacity of the lip pencil increases, in order to accommodate more lip gloss liquid, the pen body often needs to be designed longer. At this time, the limitations of the traditional end-pressing method are exposed. When using, the user needs to adjust the hand posture to be able to reach and press the end of the pen body. This operation is not only laborious, but also may cause instability during use, thus affecting the uniform application of the lip gloss. Content of the Utility Model

[0029] Referring to Figures 1 to 3 , the following embodiments are made for the pressing lip pen of the present utility model:

[0030] The pressing lip pen includes a hollow pen barrel 100, and a vacuum bottle body 200, a pumping assembly 300, and a liquid outlet assembly 400 are sequentially arranged in the hollow pen barrel 100 from bottom to top. The vacuum bottle body 200 is used to store liquid, the pumping assembly 300 is used to pump the liquid from the solvent chamber to the liquid outlet assembly 400 to achieve quantitative liquid outlet. The hollow pen barrel 100 is provided with a pressing hole, and a pressing button is arranged at the position of the pressing hole for pressing and driving the pumping assembly 300 to pump liquid. The solvent chamber 200 is arranged in the vacuum bottle body 200, the solvent chamber 200 is a hollow structure, and a solvent chamber piston 210 is slidably arranged inside the solvent chamber 200. In some other embodiments, the solvent chamber 200 can be directly arranged inside the hollow pen barrel 100 and integrally arranged.

[0031] A long pen cap 110 is arranged at the upper end of the hollow pen barrel 100, and a short pen cap 120 is arranged at the lower end of the hollow pen barrel 100. The long pen cap 110 plays a role in protecting the liquid outlet assembly 400 to prevent the liquid outlet assembly 400 from being soiled by foreign substances, and the short pen cap 120 plays a role in protecting the solvent chamber. Both the long pen cap 110 and the short pen cap 120 can be snap-connected to the hollow pen barrel 100, or both can be thread-connected to the hollow pen barrel 100.

[0032] The pumping assembly 300 includes a pump core valve body 310 that is fixedly arranged in the hollow pen barrel 100 by threads. The inlet end of the pump core valve body 310 is connected to the bottle mouth of the vacuum bottle body 200. A one-way valve 320 is arranged at the inlet end. The one-way valve 320 only allows liquid to flow from the bottle mouth of the vacuum bottle body 200 into the pump core valve body 310. The one-way valve 320 is a prior art and will not be elaborated in the present utility model.

[0033] The bottle mouth of the vacuum bottle body 200 is detachably connected to the inlet end of the pump core valve body 310.

[0034] After the vacuum bottle is used up, a new vacuum bottle filled with liquid can be replaced. The vacuum bottle is inserted into the hollow pen barrel 100 from the lower end of the hollow pen barrel 100. The outer side wall of the vacuum bottle is provided with internal and external threads, and the corresponding position of the hollow pen barrel 100 is provided with external threads. The vacuum bottle is threadedly connected to the hollow pen barrel 100 to fix the vacuum bottle, making the connection between the vacuum bottle and the pump core valve body 310 more secure.

[0035] A pump core piston 330 is movably arranged up and down in the pump core valve body 310, and a lock cover 340 is also provided. The lock cover 340 is used to be snap-fitted and fixed to the pump core valve body 310. The lock cover 340 is sleeved in the pump core valve body 310, the pump core piston 330 is sleeved in the lock cover 340, and the pump core lower pump rod 350 is sleeved in the pump core piston 330. The outer diameter of the lock cover 340 gradually increases from top to bottom. As the pump core lower pump rod 350 moves downward, the lock cover 340 is snap-fitted into the pump core valve body 310, and at the same time, it blocks the pump core piston 330 from continuing to move downward, and the liquid outlet 351 of the pump core lower pump rod 350 is exposed.

[0036] The lower end of the pump core upper pump rod 360 is sleeved on the upper end of the pump core lower pump rod 350. The pump core upper pump rod 360 abuts against the pump core piston 330. The pump core lower pump rod 350, the pump core piston 330, the pump core valve body 310, and the check valve 320 form a vacuum chamber. The lower end of the pump core lower pump rod 350 is a closed end, and the closed end is provided with a clamping block 352 that abuts against the pump core piston 330. In this embodiment, the clamping block 352 is frustum-shaped. The closed end is beneficial to forming a vacuum chamber, and the clamping block 352 fixes the pump core lower pump rod 350 in the pump core piston 330.

[0037] The side surface of the pump core lower pump rod 350 is provided with a liquid outlet 351. The outer peripheral wall of the pump core upper pump rod 360 is provided with a limiting step 361. The elastic member includes a spring 370. The spring 370 is sleeved on the pump core upper pump rod 360 and abuts against the limiting step 361 and the pump core piston 330 at the same time. The elastic member makes the pump core upper pump rod 360 away from the pump core piston 330. In other embodiments, the elastic member is an elastic sheet.

[0038] Guide blocks are provided on both sides of the pump core lower pump rod 350, so that the pump core lower pump rod 350 is slidably arranged on the inner side wall of the hollow pen barrel 100, improving the stability of sliding.

[0039] The liquid outlet assembly 400 includes a fixed pipe fitting 410, a liquid outlet head 420, and a connecting member 430. The lower end of the fixed pipe fitting 410 is provided at the upper end of the hollow pen barrel 100. The liquid outlet head 420 is sleeved on the lower end of the fixed pipe fitting 410. The connecting member 430 is arranged inside the fixed pipe fitting 410 and is respectively connected to the upper pump rod 360 of the pump core and the liquid outlet head 420. The liquid outlet end of the liquid outlet head 420 is provided with an inclined liquid outlet surface, which can better evenly apply the liquid to the lips, meeting the usage habits of consumers.

[0040] Both the liquid outlet head 420 and the fixed pipe fitting 410 are made of silica gel. The anti-aging property of silica gel ensures good sealing performance and durability during long-term use, effectively preventing liquid leakage. In some other embodiments, the liquid outlet head 420 can also be replaced by a liquid outlet brush. The liquid outlet brush is usually made of soft and water-absorbent bristles, which can evenly and finely apply the liquid to the target area.

[0041] The button member 500 is installed on the surface of the hollow pen barrel 100. The button member 500 includes a button connected to the upper pump rod 360 of the pump core. The button is configured to move the upper pump rod 360 of the pump core and the lower pump rod 350 of the pump core towards the solvent chamber direction to squeeze the vacuum chamber and drive the liquid outlet 351 to leak out simultaneously.

[0042] The button can be made of durable and comfortable-to-touch silica gel or ABS plastic, ensuring that users can feel good tactile feedback during use, while having good abrasion resistance and anti-aging performance. And it conforms to the ergonomic principle, facilitating single-handed operation by users. Its layout position is on the surface of the hollow pen barrel 100, which is easy to reach and does not interfere with other operations, ensuring that users can easily press it.

[0043] Specifically, the upper pump rod 360 of the pump core is provided with a guiding block, and the button is provided with an inclined guiding surface that is slidably connected to the guiding block. Specifically, the design of the button fully considers the convenience and smoothness of user operation. It can not only respond to the pressing action, but also cleverly utilize the mechanical principle to convert this simple pressing into the precise movement of the internal structure of the pump core. When the button is pressed, it does not work alone, but realizes a guiding sliding connection through cooperation with the guiding block designed on the upper pump rod 360 of the pump core. The key to this connection lies in the specially designed inclined guiding surface on the button surface, which closely fits the guiding block, ensuring smoothness and precision during the pressing process.

[0044] As the button is gradually pressed down, the interaction between its inclined guiding surface and the guiding block guides the upper pump rod 360 of the pump core to move along a predetermined trajectory towards the solvent chamber. This movement not only compresses the vacuum chamber inside the pump core, generating the necessary pressure difference, but also cleverly drives the lower pump rod 350 of the pump core and the entire pump core system to work in coordination. Ultimately, this series of precise linkage effects enables the liquid to flow smoothly out of the solvent chamber through the liquid outlet 351, meeting the actual needs of users.

[0045] The entire design process reflects the attention to details and the respect for user experience. By optimizing the pressing feel of the button, enhancing the transmission efficiency of the pump core system, and ensuring the stability and continuity of liquid outflow, this button assembly brings a more convenient, efficient, and pleasant user experience.

[0046] The vacuum bottle body 200 is provided with a solvent chamber piston 210. When filled with liquid, the solvent chamber piston 210 is located at the tail end of the vacuum bottle body 200. As the liquid flows out unidirectionally from the vacuum bottle mouth, the solvent chamber piston 210 is pushed towards the bottle body by the atmospheric pressure and continuously approaches the vacuum bottle mouth. The piston 210 is also made of elastic rubber material, which can play a good sealing role.

[0047] Press the button to drive the movement of the upper pump rod 360 of the pump core, and then drive the lower pump rod 350 of the pump core to move towards the solvent chamber, making the air pressure in the vacuum chamber less than the atmospheric pressure. The external atmospheric pressure causes the liquid in the solvent chamber to flow into the vacuum chamber, and then the liquid enters the lower pump rod 350 of the pump core, the upper pump rod 360 of the pump core, and the liquid outlet assembly 400 to flow out through the liquid outlet 351 that leaks when pressed.

[0048] When the button is released, the specific design of the liquid outlet assembly 400 makes the liquid outlet 351 that leaked when previously pressed exactly in the right position, allowing the liquid to flow out slowly under the action of gravity. This pressing type liquid outlet structure is not only easy to operate, but also can achieve quantitative liquid outflow, effectively avoiding problems such as liquid leakage and deterioration caused by excessive or improper operation. The entire liquid outflow process is both efficient and hygienic.

[0049] The utility model has the advantages of simple operation, safety and reliability, simple structure, not easy to break down, and convenient maintenance. Users only need to press the button gently to achieve the quantitative and smooth outflow of the liquid, without complex operation steps or additional tool assistance; Safe and reliable: The design of the button component 500 and the pump core system fully considers the safety issues during use. By restricting the pressing stroke and force of the button, damage or liquid leakage caused by excessive extrusion is prevented.

[0050] The preferred embodiments of the present utility model have been specifically described above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
