Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to a self-cleaning cosmetic packaging bottle. Background Technology

[0002] In the cosmetics industry, liquid cosmetics (such as foundation, serum, and lotion) widely adopt pump-type packaging due to the need for convenient use and controllable dosage. These bottles mainly consist of a bottle body, a liquid reservoir, a pump head assembly, and a dispensing tube. When in use, pressing the pump head utilizes the internal pressure change to draw the liquid cosmetic from the bottle along the dispensing tube, thus achieving a measured dispensing.

[0003] However, traditional pump-type cosmetic bottles generally suffer from unavoidable technical defects during long-term use: after each pump dispensing, some liquid cosmetic inevitably remains on the inner wall of the dispensing tube. Since the dispensing tube is in direct contact with the outside air, this residue is prone to drying and solidifying. On the one hand, with increased use, the dried cosmetic gradually accumulates on the inner wall of the dispensing tube, which can narrow the dispensing channel, reducing subsequent dispensing volume and causing uneven dispensing; on the other hand, it can completely block the dispensing tube, preventing the pump from dispensing properly, directly affecting the functionality of the bottle and shortening the overall product lifespan. Furthermore, the dried residue cannot be effectively reused, resulting in unnecessary waste of cosmetic ingredients and increasing the cost for consumers. Utility Model Content

[0004] The main purpose of this invention is to provide a self-cleaning cosmetic packaging bottle, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a self-cleaning cosmetic packaging bottle, comprising: Packaging bottles; A connecting cap, the connecting cap being threaded onto the top of the packaging bottle; The pump body is fixedly installed inside the connecting cap, and the lower end of the pump body is connected to a suction pipe; The outlet pipe is slidably inserted into the upper side wall of the connecting cap and extends into the pump body; A connecting tube, which is slidably inserted into the outlet tube; The pressing head is fixedly installed at the upper end of the connecting tube, and the pressing head is provided with a liquid outlet.

[0016] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-5This utility model provides a self-cleaning cosmetic packaging bottle, including: a packaging bottle 1, a connecting cap 2, a pump body 3, a liquid outlet tube 4, a connecting tube 5, a pressing head 6, and a self-cleaning mechanism 7. The packaging bottle 1 is the core storage component for cosmetics, forming a sealed liquid storage space inside to hold liquid cosmetics such as foundation, serum, and lotion, providing the basic support for the entire packaging bottle and serving as the core carrier for cosmetic storage. The connecting cap 2 is connected to the top of the packaging bottle 1 via threads, enabling the packaging bottle 1 and the upper components such as the pump body 3 to be detachably fixed, facilitating subsequent maintenance of the pump body 3 or replenishment of cosmetics into the packaging bottle 1. The pump body 3 is fixedly installed inside the connecting cap 2 and is the core power component for extracting cosmetics. The suction tube 31 is connected to the lower end of the pump body 3, and its lower end extends to the bottom of the packaging bottle 1, transporting the liquid cosmetics in the packaging bottle 1 into the pump body 3, providing a raw material channel for subsequent liquid dispensing. The outlet tube 4 is slidably inserted into the upper side wall of the connecting cap 2 and extends into the pump body 3. It is the key channel for conveying cosmetics from the pump body 3 to the outside. Cosmetics inside the pump body 3 can flow upward through the outlet tube 4, and its internal space also provides installation and movement space for the self-cleaning mechanism 7 and the connecting tube 5. The connecting tube 5 is slidably inserted into the outlet tube 4, serving to connect the outlet channel of the pump body 3 and the pressing head 6, and can convey cosmetics in the outlet tube 4 to the pressing head 6. The pressing head 6 is fixed to the upper end of the connecting tube 5 and is the direct part operated by the user. The user drives the pump body 3 to work by pressing the pressing head 6, and the outlet 61 in the pressing head 6 is connected to the connecting tube 5, so that the cosmetics are finally discharged from the outlet 61 for the user to use. The self-cleaning mechanism 7 consists of a scraping unit and a magnetic suction unit. It is the core component of this utility model to realize the "self-cleaning" function. It can scrape and clean the cosmetic residue on the inner wall of the dispensing tube 4 each time the user presses to take out the cosmetic, so as to avoid the dry accumulation of the cosmetic residue, which would cause poor dispensing or blockage. At the same time, it can recycle the cosmetic residue and reduce waste.

[0020] Further explanation: The scraping unit includes four connecting rods evenly arranged around the inner wall of the outlet pipe 4. One end of each rod is fixed to the inner wall of the outlet pipe 4, and the other end connects to the support 71, forming a stable fixed support structure. The support 71 serves as the mounting base for the first spring 73, and its position remains fixed, ensuring that the force direction and deformation state of the first spring 73 remain stable during the movement of the scraper 72, providing reliable support for the scraper 72 to reset and scrape. The scraper 72 is located above the support 71, with its outer wall tightly fitted to the inner wall of the outlet pipe 4, allowing it to slide up and down along the inner wall. The first spring 73 connects the scraper 72 and the support 71, and in its natural state, it is slightly extended, keeping the scraper 72 in its initial low position. When the scraper 72 is driven upward by magnetic force, the first spring 73 is stretched and stores energy; when the magnetic force is less than the spring tension, the first spring 73 releases its elastic force, pulling the scraper 72 downward, completing the scraping action on the inner wall of the outlet pipe 4.

[0021] Further explanation: The magnetic attraction unit includes an annular magnet 74 embedded in the lower end of the connecting tube 5. The annular magnet 74, embedded in the lower end of the connecting tube 5, is the key power source for driving the scraper 72. It acts on the ferromagnetic scraper 72 through magnetic attraction. When the connecting tube 5 moves up and down, the annular magnet 74 moves synchronously. By changing the distance between it and the scraper 72, the magnetic force is adjusted to achieve the switching between "attracting and moving the scraper upward" and "weakening the magnetic force and releasing the scraper". The first annular boss 75 is fixed to the upper part of the outer wall of the connecting tube 5, and cooperates with the upper end of the liquid outlet tube 4 to form the installation space of the second spring 76. The second spring 76 is sleeved on the outside of the connecting tube 5, with its two ends connected to the first annular boss 75 and the upper end of the liquid outlet tube 4, respectively. In its natural state, it is in an extended state, supporting the connecting tube 5 and the pressing head 6 to maintain the initial high position. When the user presses the press head 6, the connecting tube 5 moves downward, and the first annular boss 75 compresses the second spring 76 to store energy; after the user releases the press head 6, the second spring 76 releases its elastic force to push the connecting tube 5 back to its original position, providing power for the reciprocating motion of the connecting tube 5.

[0022] To further explain, the scraper 72 is equipped with multiple liquid passage holes 721 on its upper ring to ensure normal delivery of cosmetics. The liquid passage holes 721 allow the cosmetics delivered by the pump body 3 to pass smoothly through the scraper 72 and enter the connecting pipe 5, achieving compatibility between the "cleaning" and "liquid dispensing" functions without affecting the scraping action of the scraper 72, ensuring normal use by the user.

[0023] To further explain, the two symmetrical guide grooves 41 opened on the inner wall of the discharge pipe 4, together with the two matching guide blocks 722 fixed on the outer wall of the scraper 72, form a guide structure. During the up-and-down movement of the scraper 72, the guide blocks 722 always slide along the guide grooves 41, which can strictly limit the movement direction of the scraper 72, prevent the scraper 72 from rotating or deviating, and ensure that the outer wall of the scraper 72 is always fully in contact with the inner wall of the discharge pipe 4.

[0024] To further explain, the lower end of the outlet pipe 4 is provided with multiple inlet holes 42, the lower part of the outer wall of the outlet pipe 4 is fixedly connected with a second annular boss 43, the lower end of the outlet pipe 4 is fixedly connected with an inlet pipe 44, the pump body 3 is provided with a piston 8 inside, the piston 8 is sleeved on the outside of the outlet pipe 4, the lower end of the pump body 3 is provided with a ball 9, and a third spring 10 is provided between the inlet pipe 44 and the ball 9.

[0025] To further explain, the inlet hole 42 is the only entrance for cosmetics to enter the outlet pipe 4 inside the pump body 3. When the pressure inside the pump body 3 increases, the cosmetics enter the outlet pipe 4 through the inlet hole 42, providing a channel for subsequent upward delivery to the connecting pipe 5. The diameter and number of holes must match the discharge volume of the pump body 3 to ensure stable cosmetic delivery efficiency. The second annular boss 43 cooperates with the piston 8 inside the pump body 3, limiting the range of motion of the piston 8. When the piston 8 moves up and down with the outlet pipe 4, the second annular boss 43 can prevent the piston 8 from moving excessively downward and dislodging from the outlet pipe 4, or from moving excessively upward and causing the seal inside the pump body 3 to fail, ensuring that the piston 8 always moves within the effective working range, guaranteeing the stability and sealing of the pump body 3's discharge. The inlet pipe 44 connects the outlet pipe 4 with the lower space of the pump body 3, serving as a transition channel for cosmetics to enter the outlet pipe 4 from the pump body 3. At the same time, its interior provides installation space for the third spring 10, ensuring the stable installation position of the third spring 10 and the ball 9, achieving unidirectional control of the pump body 3's inlet and outlet. Piston 8 is the core component for changing the pressure inside pump body 3. When the user presses the press head 6, the connecting pipe 5 moves the outlet pipe 4 downward, and the outlet pipe 4 pushes the piston 8 downward within pump body 3, compressing the space inside pump body 3 and increasing the pressure inside pump body 3, thus pushing the cosmetics to flow into outlet pipe 4. After releasing the press head 6, piston 8 moves upward with outlet pipe 4, the space inside pump body 3 expands, the pressure decreases, and the cosmetics are drawn from packaging bottle 1 through suction pipe 31, completing the suction and discharge cycle of pump body 3. The ball 9 fits tightly against the inner wall of pump body 3, forming a one-way sealing structure; the third spring 10 connects inlet pipe 44 and ball 9, and is in an extended state in its natural state, pushing ball 9 to seal the lower inlet of pump body 3, preventing the cosmetics inside pump body 3 from flowing back into suction pipe 31. When the pressure inside the pump body 3 increases, the pressure of the cosmetic on the ball 9 is greater than the elastic force of the third spring 10, the ball 9 moves down, and the cosmetic enters the outlet pipe 4; when the pressure inside the pump body 3 decreases and the liquid is drawn in, the external atmospheric pressure pushes the cosmetic through the suction pipe 31 to push open the ball 9 and enter the pump body 3, realizing the unidirectional flow of the cosmetic.

[0026] To further explain, the scraper 72 is made of ferromagnetic material.

[0027] To further explain, both the inner walls of the outlet pipe 4 and the inlet pipe 44 are coated with a hydrophobic coating. This hydrophobic coating is made of polytetrafluoroethylene (PTFE), which significantly reduces the adhesion between cosmetics and the pipe wall. On the one hand, this reduces the amount of cosmetic residue on the pipe wall; on the other hand, even if a small amount of cosmetic residue remains, it can be more easily scraped off by the scraper 72 thanks to the hydrophobic coating, preventing the residue from drying and hardening on the pipe wall, further improving the self-cleaning effect, and reducing cosmetic waste.

[0028] It should be noted that this utility model is a self-cleaning cosmetic packaging bottle. During use, the second spring 76 is extended, supporting the connecting tube 5 and the pressing head 6 at a high position via the first annular protrusion 75. The annular magnet 74 at the lower end of the connecting tube 5 is located above the dispensing tube 4, relatively far from the scraper 72, resulting in a weaker magnetic force. The scraper 72, slightly supported by the first spring 73, is initially positioned low within the dispensing tube 4. The guide block 722 is located below the guide groove 41, and the outer wall of the scraper 72 is tightly fitted against the inner wall of the dispensing tube 4. The third spring 10 is extended, pushing the ball 9 to seal the lower inlet of the pump body 3. A certain amount of cosmetic is stored inside the pump body 3, preparing for the first dispensing. The user presses down on the pressing head 6, causing the connecting tube 5 to slide downwards along the inside of the dispensing tube 4. The first annular protrusion 75 on the outer wall of the connecting tube 5 moves downward synchronously with the connecting tube 5, compressing the second spring 76. The second spring 76 is compressed and stores elastic potential energy, providing power for the subsequent reset of the connecting tube 5. During the downward movement of the connecting tube 5, the annular magnet 74 at its lower end moves downward as well, gradually shortening the distance between it and the scraper 72, which is initially in a low position. Since the scraper 72 is made of ferromagnetic material, the magnetic attraction of the annular magnet 74 to the scraper 72 gradually increases as the distance shortens, eventually attracting the scraper 72. At the same time, the connecting tube 5 drives the outlet tube 4 downward, and the outlet tube 4 pushes the piston 8 inside the pump body 3 downward. The space inside the pump body 3 is compressed, the pressure increases, and the cosmetics inside the pump body 3 enter the outlet tube 4 through the inlet tube 44 and the inlet hole 42 at the lower end of the outlet tube 4 in sequence. Then, it flows upward, passes through the liquid passage hole 721 on the scraper 72, enters the connecting tube 5, and is finally discharged from the outlet 61 of the pressing head 6, allowing the user to complete the use of the cosmetics. When the user releases the press head 6, the compressed second spring 76 releases its elastic potential energy, generating an upward elastic force that acts on the first annular boss 75. This pushes the first annular boss 75, causing the connecting tube 5 to slide upward along the outlet tube 4, gradually returning the connecting tube 5 to its initial high position. During the upward movement of the connecting tube 5, the lower annular magnet 74 moves upward synchronously. Since the annular magnet 74 and the scraper 72 are in an attracted state, the annular magnet 74 uses magnetic force to drive the scraper 72 upward along the outlet tube 4. The guide block 722 moves upward synchronously along the guide groove 41, preventing the scraper 72 from deviating. As the scraper 72 moves upward with the annular magnet 74, the distance between it and the support 71 gradually increases. The first spring 73 connecting the two is gradually stretched, and the elastic potential energy continuously accumulates. The downward pulling force of the first spring 73 on the scraper 72 gradually increases with the increase of the stretching degree. When the connecting tube 5 approaches the initial high position, the distance between the annular magnet 74 and the scraper 72 reaches its maximum, and the magnetic force drops to its minimum. At this time, the tension of the first spring 73 is greater than the magnetic force of the annular magnet 74, and the scraper 72 completely separates from the annular magnet 74.The first spring 73 rapidly releases its stored elastic potential energy, generating a downward pulling force that causes the scraper 72 to slide rapidly downwards along the outlet pipe 4. The outer wall of the scraper 72 fits tightly against the inner wall of the outlet pipe 4. During the downward movement, it scrapes off the cosmetic residue on the inner wall of the outlet pipe 4, and the scraped-off cosmetic residue falls to the lower part of the outlet pipe 4. Under the action of the first spring 73, the scraper 72 eventually returns to its initial low position, and the guide block 722 returns to the lower part of the guide groove 41. At the same time, the outlet pipe 4 moves upwards along with the connecting pipe 5, causing the piston 8 to move upwards within the pump body 3. The space inside the pump body 3 expands, the pressure decreases, and the cosmetic residue in the packaging bottle 1, under the action of external atmospheric pressure, pushes open the bead 9 through the suction pipe 31 and enters the pump body 3, completing the suction. After the cosmetic residue enters, the bead 9, under the elastic force of the third spring 10, reseals the lower inlet of the pump body 3, and the entire device returns to its initial state, waiting for the next press. During the next dispensing, the scraped-off cosmetic residue will be discharged along with fresh cosmetic residue, realizing the utilization of residue.
