Description

Technical Field

[0001] This utility model relates to the technical field of syringe-type squeeze eye cream bottles, and in particular to a syringe-type squeeze eye cream bottle. Background Technology

[0002] As a refined skincare product targeting the delicate skin around the eyes, the packaging design of eye cream is not only crucial for ensuring product quality and maintaining the activity of the cream, but also a vital element directly impacting the user experience and convenience. With the growing acceptance of environmental protection and sustainable consumption concepts, a packaging solution that is both practical and economical, effectively reducing resource waste and lowering user costs, has become an inevitable trend driving brand development and meeting market demands.

[0003] However, in current technology, eye cream packaging generally adopts an integrated design of the bottle body and pump head or cap, with a tightly packed and inseparable structure. This design means that once the eye cream is used up, the entire packaging unit becomes unusable and can only be discarded as disposable waste. This not only causes serious resource waste and environmental pollution, contradicting the trend of green and environmentally friendly consumption, but also forces consumers to continuously pay for the packaging itself, significantly increasing the long-term cost of the product and making it economically unsound.

[0004] Therefore, those skilled in the art have provided a syringe-type squeeze eye cream bottle to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a syringe-type squeeze eye cream bottle. This bottle features a threaded interface and a snap-fit ​​connection that allows for modular replacement of the vacuum tube. Once the eye cream is used up, users can easily replace it by simply twisting and pulling it out. This not only solves the problem of traditional packaging being difficult to disassemble but also enables the reuse of packaging, reducing plastic waste at the source and significantly improving the product's economic and environmental value.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A syringe-type squeeze eye cream bottle includes an outer shell, a vacuum tube disposed inside the outer shell, a piston sliding inside the vacuum tube, a threaded cylinder threaded to one end of the vacuum tube via a threaded connector, a ball valve disposed inside the threaded cylinder, one end of the ball valve being inside the vacuum tube, and the other end extending to the outside of the threaded cylinder; A push block is provided on one side of the inner side of the outer shell, and a locking block is provided on one side of the push block. A locking groove is provided on one side of the inner side of the vacuum tube, and the locking groove engages with the locking block. One end of the outer shell is externally engaged with a connector, an injection head is internally engaged with the connector, one end of the injection head extends to the outside of the connector, and an end cap is fitted onto the outside of the connector. Through the above technical solution, the vacuum tube can be modularly replaced by threaded interface and snap-fit ​​connection. After the eye cream is used up, the user can easily replace it by simply twisting and pulling. This not only solves the drawback of traditional packaging being difficult to disassemble, but also realizes the reuse of packaging, reduces plastic waste from the source, and significantly improves the economic and environmental value of the product.

[0007] Furthermore, two guide grooves are provided on one side of the inner side of the outer shell, and guide blocks are fixedly connected to the upper and lower ends of the outer side of the push block. The two guide blocks are slidably connected to the corresponding guide grooves. Through the above technical solution, the sliding cooperation between the guide groove and the guide block provides precise linear guidance for the movement of the push block. This ensures a smooth and stable pressing process and effectively prevents the push block from deviating or jamming when force is applied. This ensures that the internal piston can stably and accurately complete the pumping and pushing actions, improving the reliability of operation and the overall service life of the product.

[0008] Furthermore, two locking blocks are fixedly connected to the upper and lower outer ends of the connector, and two locking grooves adapted to the locking blocks are opened on the inner wall of the end cap, and the two locking grooves are engaged with the two locking blocks. Through the above technical solution, the second locking block on the connector and the second locking groove inside the end cap are connected by a locking mechanism, realizing the quick and reliable installation of the end cap and the connector. When in use, the user can easily pull out the end cap to expose the injection head. After use, the end cap can be conveniently snapped back and locked. The operation is simple and efficient, greatly facilitating the user's daily carrying and use.

[0009] Furthermore, the ball valve includes a valve body and a valve ball disposed inside the valve body. The valve body has a through hole for the valve ball to move, and one end of the valve body is in contact with one end of the injection head. Through the above technical solution, the ball valve with the ball structure uses the pressure difference between the ball's own weight and the liquid to achieve automatic opening and closing. When pressed, the liquid pressure pushes the ball open to release the liquid. When the pressing stops, the ball automatically returns to its original position and fits tightly, forming a reliable one-way seal. This effectively prevents leakage or backflow of the contents when not in use, ensuring the hygiene of the product and the activity of the ointment.

[0010] Furthermore, a sealing ring is provided between the piston and the inner wall of the vacuum tube; By using the above technical solution, a sealing ring is set between the piston and the inner wall of the vacuum tube, which greatly enhances the airtightness when the piston moves. This ensures that when the piston is pushed, the eye cream can be effectively prevented from flowing back or leaking sideways, thereby stably and efficiently pushing out the eye cream in the vacuum tube completely, significantly improving the utilization rate of the liquid and the user experience.

[0011] This utility model has the following beneficial effects: 1. This utility model proposes a syringe-type squeeze eye cream bottle. Through the design of a threaded interface and a snap-fit ​​connection, the eye cream inside the vacuum tube can be easily replaced after use. Users only need to unscrew the threaded cylinder and pull out the push block at one end to remove the empty vacuum tube and replace it with a new one, realizing plug-and-play eye cream. This design not only greatly facilitates users' subsequent replenishment and replacement, effectively avoiding the disadvantages of difficulty in replacement due to the complex bottle structure, but also realizes the reuse of packaging, reducing the generation of plastic waste from the source, and significantly improving the economic and environmental value of the product.

[0015] Reference Figure 1-5 This utility model provides a specific implementation method: A syringe-type squeeze eye cream bottle includes an outer shell 1, a vacuum tube 5 is disposed inside the outer shell 1, a piston 6 slides inside the vacuum tube 5, a threaded cylinder 8 is threaded onto one end of the vacuum tube 5 through a threaded connector, a ball valve 7 is disposed inside the threaded cylinder 8, one end of the ball valve 7 is inside the vacuum tube 5, and the other end extends to the outside of the threaded cylinder 8. A push block 4 is provided on one side of the inner side of the outer casing 1, and a locking block 13 is provided on one side of the push block 4. A slot 12 is provided on one side of the inner side of the vacuum tube 5, and the slot 12 engages with the locking block 13. One end of the outer shell 1 is externally connected to a connector 2, and an injection head 3 is internally connected to the connector 2. One end of the injection head 3 extends to the outside of the connector 2, and an end cap 9 is sleeved on the outside of the connector 2. It achieves modular replacement of vacuum tube 5 through threaded interface and snap-fit ​​connection. After the eye cream is used up, the user can easily replace it by simply twisting and pulling. This not only solves the drawback of traditional packaging being difficult to disassemble, but also realizes the reuse of packaging, reduces plastic waste from the source, and significantly improves the economic and environmental value of the product.

[0016] Two guide grooves 10 are provided on one side of the inner side of the outer casing 1. Guide blocks 11 are fixedly connected to the upper and lower ends of the outer side of the push block 4. The two guide blocks 11 are slidably connected to the corresponding guide grooves 10. The sliding cooperation between the guide grooves 10 and the guide blocks 11 provides precise linear guidance for the movement of the push block 4. This ensures a smooth and stable pressing process and effectively prevents the push block 4 from deflecting or jamming when force is applied. This ensures that the internal piston 6 can stably and accurately complete the liquid drawing and pushing actions, improving the reliability of operation and the overall service life of the product. Two locking blocks 14 are fixedly connected to the upper and lower ends of the outer side of the connector 2. Two locking slots 15 that are adapted to the locking blocks 14 are provided on the inner wall of the end cap 9. The two locking slots 15 are engaged with the two locking blocks 14. The locking blocks 14 on the connector 2 and the locking slots 15 inside the end cap 9 are engaged to achieve quick and reliable installation of the end cap 9 and the connector 2. When in use, the user can easily pull out the end cap 9 to expose the injection head 3. After use, the end cap 9 can be easily snapped back and locked, making operation simple and efficient, greatly facilitating daily carrying and use. The ball valve 7 includes a valve body and a valve ball located inside the valve body. The valve body has a through hole for the valve ball to move. One end of the valve body is attached to one end of the injection head 3. The ball valve 7, which adopts a valve ball structure, uses the pressure difference between the valve ball and the liquid to achieve automatic opening and closing. When pressed, the liquid pressure pushes the valve ball open to complete the dispensing. When the pressing stops, the valve ball automatically returns to its original position and fits tightly, forming a reliable one-way seal, effectively preventing leakage or backflow of the contents when not in use, ensuring the hygiene of the product and the activity of the ointment. A sealing ring is provided between the piston 6 and the inner wall of the vacuum tube 5. The sealing ring between the piston 6 and the inner wall of the vacuum tube 5 greatly enhances the airtightness of the piston 6 when it moves. This ensures that when the piston 6 is pushed, it can effectively prevent the eye cream from flowing back or leaking, thereby stably and efficiently pushing out the eye cream in the vacuum tube 5 completely, significantly improving the utilization rate of the dispensed liquid and the user experience.

[0017] Working Principle: In use, the user first removes the end cap 9 to expose the injection head 3. Then, the user simply presses down on the actuating block 4, which directly drives the piston 6 to move smoothly downwards within the vacuum tube 5. The movement of piston 6 pushes the eye cream forward. When the pressure of the eye cream accumulates enough to overcome the preset resistance of the ball valve 7, the ball valve 7 opens, and the eye cream is precisely and residue-free dispensed through the injection head 3. When pressing stops, piston 6 returns to its original position under internal pressure, and the ball valve 7 automatically closes, effectively preventing leakage or backflow of the cream, significantly improving the user experience and cost-effectiveness.

[0018] When the eye cream in the vacuum tube 5 is used up, the user simply unscrews the connector 2 and pulls out the push block 4 to easily remove the entire vacuum tube 5 as a replaceable inner liner and insert a new vacuum tube 5. This design not only greatly facilitates subsequent replenishment and replacement for users, effectively avoiding the drawbacks of difficulty in replacement due to the complex structure of the bottle, but also realizes the reuse of packaging, reducing the generation of plastic waste from the source and significantly improving the economic and environmental value of the product.
