Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic storage pens, in particular to an air-proof lip glaze pen. Background Technique

[0002] Existing lip glaze pastes usually use PE tubes as packaging containers. When in use, users need to press the PE tube to squeeze out the lip glaze paste. However, due to design deficiencies, the amount of lip glaze paste squeezed out each time is often difficult to control, which not only causes great waste but also affects the user experience. More seriously, when the user releases the PE tube, the PE tube will inevitably inhale air during the process of restoring deformation. This not only provides a breeding ground for bacteria but also when squeezing next time, the user needs to first expel the gas in the PE tube, which undoubtedly further increases the difficulty of controlling the extrusion amount of the lip glaze paste.

[0003] In addition, after the lip glaze paste tube is used up, since its design allows refilling, this provides an opportunity for unscrupulous merchants.

[0004] Therefore, we propose an air-proof lip glaze pen to solve the above problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an air-proof lip glaze pen.

[0006] An air-proof lip glaze pen provided by the utility model includes a pen barrel. One end of the pen barrel is fixedly embedded with a discharge plug. An installation plate is fixed inside the pen barrel. A piston is slidably connected inside the pen barrel. One side of the piston is rotatably connected with a lead screw. A threaded hole threaded with the lead screw is provided in the middle of the installation plate. One end of the pen barrel away from the discharge plug is rotatably embedded with a rotary cap, and the lead screw is slidably connected with the rotary cap. Tooth-shaped card slots are evenly provided at one end of the rotary cap located at the pen barrel. An elastic arm is integrally provided at the edge of the installation plate, and a card part matching with the tooth-shaped card slots is provided on the elastic arm.

[0007] Preferably, a vertical edge for preventing the rotary cap from rotating in the reverse direction is provided on the tooth-shaped card slots.

[0008] Preferably, a fixed sleeve is provided inside the rotary cap. Notches are symmetrically provided on the side wall of the lead screw, and the notches are slidably matched with the inner wall of the fixed sleeve.

[0009] Preferably, a discharge through hole is provided on the discharge plug. An installation groove is provided on the outer side of the discharge plug. A discharge head is embedded and installed in the installation groove. A receiving groove is provided at one end of the discharge head. A spherical groove is provided on the outer side of the discharge plug opposite to the discharge through hole. A blocking ball is installed in the spherical groove. A spring is provided in the receiving groove, and the two ends of the spring are respectively connected with the blocking ball and the discharge head.

[0010] Preferably, an annular convex portion is provided inside the receiving groove, and one end of the spring is sleeved outside the annular convex portion.

[0011] Preferably, an inclined surface for cooperating with the lips is provided at the end of the discharge head.

[0012] Preferably, anti-slip lines are provided on the outer side of the rotary cap.

[0013] Preferably, a sealing cover is sleeved outside the discharge head.

[0014] Compared with the related art, the present utility model has the following beneficial effects:

[0015] Anti-air intake design: Through the unique rotary cap and lead screw structure, in cooperation with the elastic arm and the engaging portion, the one-way rotation of the lip glaze pen is achieved, effectively preventing air from entering the inside of the pen barrel, thereby avoiding the oxidation and deterioration of the lip glaze paste and extending the service life of the product. The plug ball and spring design on the discharge plug head achieve the one-way sealing of the discharge through hole, effectively preventing the accidental outflow of the lip glaze paste under its own gravity or shaking, improving the portability and safety of the product; the anti-air intake design reduces the contact opportunity between the lip glaze paste and air, thereby reducing the possibility of bacterial growth.

[0016] Accurate discharge: Each time the rotary cap is rotated, the cooperation between the engaging portion and the toothed card slot will make a sound, prompting the user that the rotary cap has rotated a specific angle, and the piston has also moved a specific distance accordingly, thereby extruding a specific amount of lip glaze paste. This design enables the user to more accurately control the usage amount of the lip glaze and avoid waste.

[0017] Preventing reverse installation: The setting of the vertical side effectively prevents the reverse rotation of the rotary cap, thereby avoiding the risk of reverse installation of the lip glaze paste. This design not only protects the interests of users from being damaged (preventing the use of unqualified or deteriorated lip glaze paste), but also reduces the risk of pirated products.

Specific embodiments

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Please refer to Figures 1 to 8 , an anti-intake lip glaze pen, comprising a pen barrel 1, one end of the pen barrel 1 is embedded and fixed with a discharge plug 2, and a mounting plate 3 is fixedly installed inside the pen barrel 1. Inside the pen barrel 1, a piston 4 is slidably connected, and the lip glaze paste is filled between the piston 4 and the discharge plug 2. One side of the piston 4 is rotatably connected with a lead screw 5, and a threaded hole threaded with the lead screw 5 is provided in the middle of the mounting plate 3. One end of the pen barrel 1 away from the discharge plug 2 is embedded and rotatably connected with a cap 6, and the lead screw 5 is slidably connected with the cap 6. Tooth-shaped card slots 7 are evenly arranged at one end of the cap 6 located in the pen barrel 1, an elastic arm 8 is integrally provided at the edge of the mounting plate 3, and a clamping part 9 matching with the tooth-shaped card slots 7 is provided on the elastic arm 8.

[0029] During use, by rotating the cap 6, since the lead screw 5 is slidably connected with the cap 6 relatively, the lead screw 5 will also rotate together with the cap 6. And because the lead screw 5 is threadedly connected with the threaded hole in the mounting plate 3, the lead screw 5 will slide relative to the cap 6 while rotating, thereby driving the piston 4 to squeeze the lip glaze paste inside the pen barrel 1. During the rotation of the cap 6, the clamping part 9 will be squeezed by the tooth-shaped card slots 7 at the end of the cap 6, causing the elastic arm 8 to deform. When the clamping part 9 moves to the position opposite to the next tooth-shaped card slot 7, it will be reinserted into the tooth-shaped card slot 7 under the restoring force of the elastic arm 8 and make a sound. Each time a sound is made, it means that the cap 6 has rotated a specific angle, and the piston 4 has also moved a specific distance, thereby extruding a specific amount of lip glaze paste.

[0030] In addition, a vertical edge portion 10 for preventing the rotary cap 6 from rotating in the reverse direction is provided on the toothed card slot 7. This design enables the rotary cap 6 to rotate only in one direction, which not only prevents air from entering the lip glaze paste between the piston 4 and the discharge plug 2, but also prevents the lip glaze paste from being installed in reverse, avoiding unscrupulous merchants from refilling unqualified lip glaze paste into the used lip glaze pen and reducing the risk of pirated products.

[0031] A fixing sleeve 11 is also provided inside the rotary cap 6. Notches 12 are symmetrically provided on the side wall of the lead screw 5. The notches 12 are in sliding fit with the inner wall of the fixing sleeve 11, which enables the lead screw 5 to slide stably relative to the rotary cap 6.

[0032] A discharge through hole 13 is provided on the discharge plug 2 for discharging the lip glaze paste. An installation groove 14 is provided on the outer side of the discharge plug 2. A discharge head 15 is embedded and installed in the installation groove 14. A receiving groove 16 is provided at one end of the discharge head 15. A spherical groove 17 is provided on the outer side of the discharge plug 2 opposite to the discharge through hole 13. A blocking ball 18 is installed in the spherical groove 17. A spring 19 is provided in the receiving groove 16. The two ends of the spring 19 are respectively connected to the blocking ball 18 and the discharge head 15. By pressing the blocking ball 18 with the spring 19, the discharge through hole 13 can be blocked unidirectionally, avoiding the lip glaze paste from flowing out of the discharge through hole 13 under the action of its own gravity or when the lip glaze pen is shaken.

[0033] In order to make the spring 19 more stable, an annular convex portion 20 is further provided inside the receiving groove 16. One end of the spring 19 is sleeved outside the annular convex portion 20. At the same time, an inclined surface 21 for cooperating with the lips is provided at the end of the discharge head 15, so that it can better contact and cooperate with the lips and is more comfortable to use.

[0034] Anti-slip lines 22 are provided on the outer side of the rotary cap 6 to play an anti-slip role.

[0035] A sealing cover 23 is sleeved on the outer side of the discharge head 15 to prevent bacteria from breeding.

[0036] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
