Description

Technical Field

[0001] This invention relates to the field of cosmetic packaging container technology, specifically to a multifunctional vacuum replacement dropper container for precise, slow-drip liquid dispensing with multiple leak-proof features. Background Technology

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are applied to any part of the human body surface, such as skin, hair, nails, lips, and teeth, by means of smearing, spraying, or other similar methods, to achieve the effects of cleansing, maintenance, beautification, modification and alteration of appearance, or correction of body odor and maintenance of a pleasant condition. Cosmetics need to be packaged in bottles for user use. Essential oil-based cosmetics generally use dropper containers as packaging bottles; however, dropper containers currently have some shortcomings in their use. 1. Because essential oils are highly fluid, traditional dropper containers cannot create a vacuum, making leakage very easy and resulting in contamination and waste. 2. Products stored in conventional dropper containers are very easily exposed to air. Exposure to air can cause oxidation in cosmetics, affecting their freshness. 3. Existing dropper containers are prone to accidental pressing during use, which can lead to liquid leakage, waste of essential oil cosmetics, and pollution. They can also spray out liquid, which can cause waste. Therefore, we have proposed a multi-functional vacuum replacement dropper container with precise quantitative slow-drip liquid and multiple leak-proof features. Summary of the Invention

[0010] Preferably, a positioning ring is fixedly connected to the side of the replacement locking member. The positioning ring is used to limit the shoulder sleeve, and the diameter of the shoulder sleeve is the same as the diameter of the lower cover.

[0011] Preferably, the outer side of the cap is fixedly connected to an arc-shaped locking point, and the inner wall of the outer bottle is provided with an arc-shaped positioning groove, the arc-shaped locking point being adapted to the arc-shaped positioning groove. This invention provides a multifunctional vacuum replacement dropper container for precise, slow-drip liquid dispensing with multiple leak-proof features, offering the following advantages: 1. This multi-functional vacuum replacement dropper container for precise, slow-drip liquid dispensing with multiple leak-proof features, achieved by adding a piston and sealing it against the inner wall of the inner liner, minimizes liquid residue. This application provides multiple leak-proof effects, including press-lock leak prevention, leak prevention in case of accidental pressure, and leak prevention during inverted replacement. By adding a replacement cap and a sealing post to the existing inner liner structure, the replacement cap supports the one-way valve on the inner liner, thus preventing spillage when the inner liner is inverted, while also ensuring forward flow of material and guaranteeing the safety of the inner liner during transportation. During the drop, the one-way valve plate is tightly pressed by the sealing column, thus ensuring the airtightness of the replacement inner liner, preventing liquid leakage, improving leak-proof performance, and avoiding the leakage that occurs during transportation and drop of traditional replacement packs. The material is isolated from the air throughout the process, achieving the purpose of preservation and anti-oxidation. The liquid outlet at the bottom of the liquid outlet is connected to the inner cavity of the W-shaped sealing block and fits snugly. With the use of the W-shaped sealing block, if the user forgets to lock the button after use, the button may be accidentally pressed, causing accidental pressure. The W-shaped sealing block at the bottom of the inner cavity of the lower cover and the inner and outer rings of the liquid outlet on the liquid outlet fit tightly to ensure a seal, thus preventing liquid leakage and waste and pollution.

[0012] 2. This multi-functional vacuum replacement dropper container, which provides precise quantitative slow-drip dispensing and multiple leak-proof features, controls the dispensing state by selecting a mesh of appropriate density according to the consistency of the material, thereby preventing material spraying and aiding in material filtration.

[0013] 3. This multi-functional vacuum replacement dropper container for precise, slow-drip liquid dispensing with multiple leak-proof features a self-lifting arc surface and connecting protrusions. When replacing the inner liner, the connecting protrusions engage with the inner cavity of the self-lifting arc surface and rotate, causing the connecting protrusions to rise along the inner cavity of the self-lifting arc surface, thus creating a self-lifting motion.

[0014] 4. This multi-functional vacuum replacement dropper container with precise quantitative slow-drip dispensing and multiple leak-proof features a dispensing nozzle installed at the bottom of the replacement locking component. The top of the replacement locking component and the lower surface of the positioning ring then contact the shoulder sleeve, allowing for its installation. The inner diameter of the shoulder sleeve is the same as the diameter of the outer bottle. The shoulder sleeve fits onto the bottom of the outer bottle, and its diameter is the same as the diameter of the lower cap. When installing the lower cap, the surface of the lower cap can be parallel to the surface of the shoulder sleeve, which is not only more aesthetically pleasing but also prevents the top of the lower cap from being damaged by impacts, thus improving the stability of the dropper container.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: Refer to Figures 1-13 This invention provides a multifunctional vacuum replacement dropper container for precise, slow-drip liquid dispensing with multiple leak-proof features, comprising an outer bottle 1, an inner liner 12, and a replacement inner liner. A push-button cap 2 is installed at the top of the inner cavity of the outer bottle 1. The upper surface of the push-button cap 2 has a pressing arc surface 18, and a locking guide surface 19 is provided on the push-button cap 2. A locking stop fitting surface 20 is provided at the top of the inner cavity of the outer bottle 1, extending into the locking guide surface 19. The inner wall at the bottom of the outer bottle 1 has a self-lifting curved surface 21. The inner liner 12 is installed inside the outer bottle 1. The top of the inner liner 12 extends into the inner cavity of the button cap 2. A piston 11 is slidably installed in the inner cavity of the inner liner 12. The piston 11 is sealed to the inner wall of the inner liner 12. A bottom plate 10 is threadedly installed on the top of the inner cavity of the inner liner 12. The bottom plate 10 is located above the piston 11 and below the button cap 2, and is in contact with the top surface of the inner cavity of the button cap 2.

[0019] By adding a piston 11 and using the piston 11 to seal against the inner wall of the inner liner 12, the amount of liquid residue can be minimized.

[0020] An inner plug 13 is fitted to the bottom of the inner cavity of the inner liner 12. A one-way valve 14 is connected to the top of the inner cavity of the inner plug 13. By adding the one-way valve 14, the material can be prevented from spilling when the inner liner is replaced by inversion, while also ensuring the forward flow of the material. A replacement inner liner cap 5 is threaded onto the bottom of the inner liner 12. A vacuum pump core 3 is installed inside the cavity of the replacement inner liner cap 5. A spring 17 is fitted onto the surface of the vacuum pump core 3. A mesh 4 is provided at the bottom of the cavity of the vacuum pump core 3. The top of the vacuum pump core 3 extends into the cavity of the inner plug 13. A replacement locking member 6 is installed on the outside of the replacement inner liner cap 5. A liquid outlet 8 is snapped onto the bottom of the replacement locking member 6. A shoulder sleeve 7 is fitted onto the surface of the replacement locking member 6. Selecting a membrane 4 with the appropriate density based on the consistency of the material enables control of the liquid discharge state, thereby preventing material ejection and aiding in material filtration.

[0021] Replacement locking part 6 is snapped into the inner cavity of outer bottle 1. A connecting protrusion 22 is fixedly connected to replacement locking part 6, and the connecting protrusion 22 is located in the inner cavity of self-lifting arc surface 21.

[0022] Through the design of the self-lifting arc surface 21 and the connecting protrusion 22, when replacing the inner liner, the connecting protrusion 22 engages with the inner cavity of the self-lifting arc surface 21 and rotates. The connecting protrusion 22 then rises along the inner cavity of the self-lifting arc surface 21, forming a self-lifting motion. The replacement inner liner has the same structure as the inner liner 12. The bottom end of the replacement inner liner is threaded with a replacement cap 15. A sealing post 16 is fixedly connected to the middle of the inner cavity of the replacement cap 15. One end of the sealing post 16 extends into the inner cavity of the inner plug 13 and contacts the one-way valve plate 14. By adding a replacement cover 15 and a sealing post 16 to the existing replacement inner liner structure, the replacement cover 15 supports the one-way valve plate 14 on the replacement inner liner and holds it against the one-way valve plate 14. This ensures that the one-way valve plate 14 is tightly pressed by the sealing post 16 during transportation and drops, thereby ensuring the airtightness of the replacement inner liner, preventing liquid leakage, improving leak-proof performance, and avoiding the leakage that occurs during transportation and drops of traditional replacement devices.

[0023] The bottom end of the dispensing nozzle 8 is fitted with a lower cover 9. The side of the dispensing nozzle 8 is provided with a connecting protrusion 23. The inner wall of the lower cover 9 is provided with a snap-fit ​​groove 24. The connecting protrusion 23 is slidably installed into the inner cavity of the snap-fit ​​groove 24. A W-shaped sealing block 28 is fixedly connected to the bottom of the inner cavity of the lower cover 9, and the W-shaped sealing block 28 is adapted to the dispensing port at the bottom end of the dispensing nozzle 8.

[0024] The liquid outlet at the bottom of the nozzle 8 is fitted into the inner cavity of the W-shaped sealing block 28, and they fit together. Using the W-shaped sealing block 28, if the user forgets to lock the button 2 after use, and the button 2 is accidentally pressed, the W-shaped sealing block 28 at the bottom of the lower cover 9 and the inner and outer rings of the liquid outlet on the nozzle 8 fit tightly together to ensure a seal, thus preventing liquid leakage, waste, and contamination. A positioning ring 25 is fixedly connected to the side of the replacement locking part 6. The positioning ring 25 is used to limit the shoulder sleeve 7. After the shoulder sleeve 7 is fitted onto the surface of the replacement locking part 6, the dispensing nozzle 8 is installed at the bottom end of the replacement locking part 6. Then, the top end of the replacement locking part 6 and the lower surface of the positioning ring 25 contact the shoulder sleeve 7, thereby installing the shoulder sleeve 7. The diameter of the inner cavity of the shoulder sleeve 7 is the same as the diameter of the outer bottle 1. The shoulder sleeve 7 is fitted onto the bottom end of the outer bottle 1. The diameter of the shoulder sleeve 7 is the same as the diameter of the lower cover 9. When installing the lower cover 9, the surface of the lower cover 9 can be made parallel to the surface of the shoulder sleeve 7, which is not only more aesthetically pleasing, but also prevents the top of the lower cover 9 from being hit or other forces, causing the lower cover 9 to loosen and fall off, thereby improving the stability of the dropper container.

[0025] An arc-shaped locking point 26 is fixedly connected to the outer side of the cap 2, and an arc-shaped positioning groove is opened on the inner wall of the outer bottle 1. The arc-shaped locking point 26 is adapted to the arc-shaped positioning groove. The button cap 2 has open and close markings, and the outer bottle 1 has a reference marking. When the arc-shaped locking point 26 is inserted into the arc-shaped positioning groove, the user can feel the touch. At this time, the button cap 2 is locked and cannot be pressed down.

[0026] In summary, this multi-functional vacuum replacement dropper container for precise, slow-drip liquid dispensing with multiple leak-proof features is used by rotating the cap 2 according to the opening and closing markings on the outer bottle 1. This causes the arc-shaped locking point 26 to move out of the arc-shaped positioning groove, indicating the open position. The lower cover 9 is then removed by rotating the cap. Next, pressing the pressing arc surface 18 on the cap 2 causes it to move downwards, transmitting force over a long distance to the inner liner 12. This deforms the spring 17 on the vacuum pump core 3, achieving the slow-drip function. When replacing the inner liner, rotate the shoulder sleeve 7 counterclockwise to make the connecting protrusion 22 on the replacement locking piece 6 rotate out of the inner cavity of the self-lifting arc surface 21. Remove the shoulder sleeve 7 and the dispensing nozzle 8 completely. Then, hold the inner liner 12 and rotate the shoulder sleeve 7 to separate the replacement inner liner cap 5 from the end of the button cap 2. After separation, rotate and remove the replacement cap 15 on the replacement inner liner. Then, thread the replacement inner liner to the replacement inner liner cap 5. Then, insert the replacement inner liner into the inner cavity of the outer bottle 1 and put on the top and bottom caps 9.
