A new type of lip gloss pen

Abstract

This utility model relates to a novel lip gloss pen. It includes: a bottle body, a cap, a press-and-extrusion module, a hollow pen barrel, and a lip gloss sponge tip. The press-and-extrusion module consists of a suction tube, a storage cylinder, a sealing bead, a lifting cylinder, a piston, and a pressing sleeve. A spring sleeve is provided at the bottom of the lifting cylinder, and a spring is installed inside the spring sleeve. The lifting cylinder also has a limiting block and a through-hole. The vertical sliding stroke of the piston is limited between the limiting block and the spring sleeve. This utility model uses a press-and-extrusion module to replenish lip gloss to the sponge tip, offering convenient use. Furthermore, because the pump volume per press is limited, excessive dripping of lip gloss from the sponge tip is less likely, thus minimizing the risk of spillage and contamination of the product and personal items.

Description

Technical Field

[0001] This utility model relates to a lip gloss pen, and more particularly to a novel lip gloss pen. Background Technology

[0002] Lip gloss pens are everyday cosmetic products that are easy to apply to the lips. Currently, there are many different designs for lip gloss pens, but some have design flaws that prevent them from holding liquid cosmetic dyes. Even if they can, there is a possibility of spillage during carrying, making them inconvenient to use and carry. To address this, a lip gloss pen has been disclosed (Publication No.: CN204654118U), comprising a blow bottle, a brush handle, and a cap. The blow bottle has an external thread on its neck. Inside the blow bottle is a brush handle equipped with a lip gloss tip, and the handle's grip end has an internal thread. The blow bottle and brush handle are fixed together by the external and internal threads. An inner plug is fitted inside the threaded end of the brush handle, which is fitted into the grip end of the brush handle. A square connecting block is provided between the grip end and the main body of the brush handle, with raised strips on all four sides. The cap has four locking strips inside that engage with the raised strips, securing the cap to the grip end of the brush handle. The advantages of this invention are: the lip gloss tip is fully moistened inside the blow bottle; and due to the inner plug, the liquid cosmetic dye inside the blow bottle will not spill out during carrying, making it convenient to carry and use.

[0003] However, in actual use, because the nozzle needs to be repeatedly inserted and removed from the blow bottle, this process causes the lip gloss absorbed on the nozzle to stain the inner stopper. The accumulated liquid on the inner stopper can easily overflow, causing the lip gloss to easily seep out from the gaps in the cap assembly. At the same time, because the blow bottle is not sealed, if it is accidentally tipped over, it can easily lead to a large amount of lip gloss overflowing. Summary of the Invention

[0004] This invention provides a novel lip gloss pen, solving the problem in the prior art where the inner stopper easily accumulates lip gloss liquid, leading to leakage.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a novel lip gloss pen, comprising: a bottle body, a bottle cap, a pressing and extruding module, a hollow pen barrel, and a lip gloss sponge tip;

[0006] The press-extrusion module is fixed to the bottle opening of the bottle body. The press-extrusion module consists of a suction tube, a liquid storage cylinder, a sealing bead, a lifting cylinder, a piston, and a pressing sleeve. The suction tube extends into the bottom of the bottle body, and the bottom of the liquid storage cylinder is connected to the suction tube. The sealing bead is movably disposed at the bottom of the liquid storage cylinder and blocks the opening of the suction tube. The bottom of the lifting cylinder is provided with a spring sleeve, and a spring is provided inside the spring sleeve. The bottom of the spring abuts against the bottom of the liquid storage cylinder. The lifting cylinder is also provided with a limiting block and a flow hole that passes through the inside and outside. The piston is movably sleeved on the outer wall of the lifting cylinder and is tightly fitted with the inner wall of the liquid storage cylinder. The up and down sliding stroke of the piston is limited between the limiting block and the spring sleeve. When the piston abuts against the limiting block, the flow hole is exposed. When the piston abuts against the spring sleeve, the flow hole is covered by the piston. The pressing sleeve is fixed relative to the lifting cylinder.

[0007] The hollow pen barrel is vertically and conductively fixed to the top of the lifting cylinder, the lip gloss sponge head is fixed to the top of the hollow pen barrel, and the bottle cap is placed on the bottle body and covers the hollow pen barrel and the lip gloss sponge head. The bottle cap can be assembled by screwing or plugging.

[0008] The working principle of this utility model is as follows: Remove the bottle cap from the bottle body, then press down on the pressing sleeve. Simultaneously, the lifting cylinder presses down. Due to the friction of the inner wall of the storage cylinder, the piston slides to abut against the limiting block. At this point, the flow hole is exposed. As the piston moves downward, the pressure inside the storage cylinder increases. The sealing bead blocks the opening of the extraction tube, causing the lip gloss in the storage cylinder to enter the lifting cylinder only through the flow hole. It is then replenished into the lip gloss sponge head via the hollow pen barrel. Then, release the pressing sleeve. The spring pushes the lifting cylinder upward to its original position. At this time, the piston, again due to the friction of the inner wall of the storage cylinder, slides to abut against the spring sleeve. The flow hole is covered by the piston, causing the pressure inside the storage cylinder to decrease. Thus, the liquid in the bottle enters the storage cylinder through the extraction tube. The sealing bead acts as a one-way valve. Therefore, this utility model allows for continuous replenishment of lip gloss on the lip gloss sponge head by repeatedly pressing the pressing sleeve, making it convenient to use. The maximum pumping volume is controlled by designing the maximum stroke of each press. The maximum pumping volume of this invention is less than the maximum water storage capacity of the lip gloss sponge head, thus avoiding liquid leakage and dripping from the lip gloss sponge head.

[0009] As the suction tube draws out the liquid, the liquid inside the bottle decreases. To ensure that the pressure inside the bottle is balanced with the external pressure, a one-way valve can be installed on the bottle, or the assembly gap between the bottle opening and the pressing and extruding module can be designed to prevent liquid from leaking out, but allow gas to be slowly replenished.

[0010] Furthermore, the pressing sleeve is fixed to the top of the lifting cylinder, and the top of the pressing sleeve is provided with a barrier ring that surrounds the hollow pen barrel. The barrier ring defines a groove for temporarily storing dripping lip gloss to prevent liquid from seeping out and dripping from the sponge tip.

[0011] Furthermore, the top of the liquid storage cylinder is provided with a sealing cap, and the lifting cylinder moves vertically through the sealing cap. When the spring returns to its original position, the limiting block will abut against the sealing cap to limit its movement. The sealing cap can provide a certain axial positioning effect for the lifting cylinder and is used to limit the lifting height of the lifting cylinder.

[0012] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model replenishes lip gloss liquid to the lip gloss sponge head by pressing and extruding the module, which is convenient to use. At the same time, since the pumping volume of each press is limited, the lip gloss sponge head is less likely to drip too much lip gloss liquid, thus avoiding the situation where the lip gloss liquid overflows and causes the product itself and personal items to be contaminated.

[0017] Example 1: See Figure 1 and Figure 2 A novel lip gloss pen includes: a bottle body 10, a bottle cap 20, a press-and-extrusion module 30, a hollow pen barrel 40, and a lip gloss sponge tip 50;

[0018] The press extrusion module is fixed at the bottle mouth. The press extrusion module consists of a suction tube 31, a liquid storage cylinder 32, a sealing bead 33, a lifting cylinder 34, a piston 35, and a pressing sleeve 36. The suction tube extends into the bottom of the bottle. The bottom of the liquid storage cylinder is connected to the suction tube. The sealing bead is movably located at the bottom of the liquid storage cylinder and blocks the opening of the suction tube. The bottom of the lifting cylinder is provided with a spring sleeve 37, and a spring 38 is provided inside the spring sleeve. The bottom of the spring abuts against the bottom of the liquid storage cylinder. The lifting cylinder is also provided with a limiting block 341 and a flow hole 342 that passes through the inside and outside. The piston is movably sleeved on the outer wall of the lifting cylinder and is tightly fitted with the inner wall of the liquid storage cylinder. The up and down sliding stroke of the piston is limited between the limiting block and the spring sleeve. When the piston abuts against the limiting block, the flow hole is exposed. When the piston abuts against the spring sleeve, the flow hole is covered by the piston. The pressing sleeve is fixed relative to the lifting cylinder.

[0019] The hollow pen barrel is vertically and fixed to the top of the lifting cylinder. The lip gloss sponge head is fixed to the top of the hollow pen barrel. The bottle cap is placed on the bottle body and covers the hollow pen barrel and the lip gloss sponge head. The bottle cap is assembled by a plug-in connection.

[0020] The operating principle of this embodiment is as follows: Remove the bottle cap from the bottle body, then press down on the pressing sleeve. Simultaneously, the lifting cylinder presses down. Due to the friction of the inner wall of the reservoir, the piston slides to abut against the limiting block, exposing the flow hole. As the piston moves downward, the pressure inside the reservoir increases, and the sealing bead blocks the opening of the extraction tube. This forces the lip gloss liquid in the reservoir to enter the lifting cylinder through the flow hole and then be supplied to the lip gloss sponge head via the hollow pen barrel. Then, release the pressing sleeve. The spring pushes the lifting cylinder upward to its original position. Again, due to the friction of the inner wall of the reservoir, the piston slides to abut against the spring sleeve, covering the flow hole. This reduces the pressure inside the reservoir, allowing the liquid in the bottle to enter the reservoir through the extraction tube. The sealing bead acts as a one-way valve. Therefore, this embodiment allows for continuous replenishment of the lip gloss liquid on the lip gloss sponge head by repeatedly pressing the pressing sleeve, making it convenient to use. The maximum pumping volume is controlled by designing the maximum stroke of each press. In this embodiment, the maximum pumping volume is less than the maximum water storage capacity of the lip gloss sponge head to avoid liquid leakage and dripping from the lip gloss sponge head.

[0021] See Figure 1 The pressing sleeve is fixed to the top of the lifting cylinder, and the top of the pressing sleeve is equipped with a barrier ring 361 that surrounds the hollow pen barrel. The barrier ring defines a groove for temporarily storing dripping lip gloss to prevent liquid from seeping out and dripping from the sponge tip. The bottom edge of the pressing sleeve is folded outwards for easy pressing with the user's fingers.

[0022] For details, see Figure 2The piston consists of an inner rubber sleeve 351, a connecting ring 352, and an outer rubber sleeve 353. The outer rubber sleeve is shaped like a <, which enhances the sealing effect of the piston.

[0023] See Figure 2 The top of the liquid storage cylinder is equipped with a sealing cap 321. The lifting cylinder moves vertically through the sealing cap. When the spring returns to its original position, the limiting block will abut against the sealing cap to limit its movement. The sealing cap can provide a certain axial positioning effect for the lifting cylinder and is used to limit the lifting height of the lifting cylinder.

[0024] See Figure 2 The top of the liquid storage cylinder is also provided with an outward flange 322, and a sealing ring 39 is placed between the outward flange and the bottle mouth of the bottle body. A compression sleeve 11 is screwed onto the bottle mouth of the bottle body, which can press the outward flange tightly onto the sealing ring. A one-way valve 12 is provided at the bottom of the bottle body for replenishing gas inside the bottle body.

[0025] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
