Description

Technical Field

[0001] This utility model relates to the field of emulsion bottle technology, specifically to an emulsion bottle that facilitates convenient squeeze-type quantitative dispensing. Background Technology

[0002] Lotion bottles are containers specifically designed for holding skincare lotions, typically made of lightweight plastic or durable glass. Their hallmark feature is a precision pump dispenser, allowing for accurate dispensing with a light press, combining hygiene and convenience. The bottle body is often transparent or frosted, making it easy to observe the remaining amount; the narrow neck and leak-proof inner stopper effectively prevent air from entering and slowing down ingredient oxidation. As a core carrier for daily chemical products, it needs to balance functionality and aesthetics, with a streamlined shape that fits the curve of the hand, and the surface can be printed with brand logos and usage instructions. Modern lotion bottles place greater emphasis on sustainability, using some recyclable materials and optimizing the structure to reduce material consumption.

[0003] As the core packaging for daily chemical products, emulsion bottles need to balance sealing, dispensing, and portability. Traditional bottles often use screw caps with tilting or single pump head structures, allowing users to dispense liquid by squeezing or pressing. However, during travel, the pump head is prone to leakage due to accidental contact, and repeated pressing often causes radial slippage, resulting in inconsistent liquid volume, making it difficult to meet precise dosage requirements. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an emulsion bottle for easy squeeze-type quantitative dispensing, including a bottle body. An externally threaded tube is fixedly connected to the top of the bottle body. An internally threaded tube is threadedly connected to the surface of the externally threaded tube. A conical pedestal is fixedly connected to the top of the internally threaded tube. A limiting sleeve is fixedly connected to the top of the conical pedestal. A limiting hole is formed on the surface of the limiting sleeve. A positioning post is fixedly connected inside the limiting hole. A pump body is installed inside the conical pedestal. A pump head is installed at the output end of the pump body. A limiting block is fixedly connected to the surface of the pump head. A collar is fixedly connected to the end of the limiting block away from the pump head. A through hole is formed at the top of the limiting block.

[0005] The above technical solution utilizes the spiral fit between the external and internal threaded tubes to fix the pump body assembly and the bottle body together. Disassembly and assembly only require rotation and no additional tools are needed. At the same time, the guide and limit system composed of the limiting sleeve, limiting hole, positioning post, limiting block, collar, and through hole ensures that the pump head can only slide vertically along the axial direction throughout the entire pressing process. This prevents radial slippage and ensures a constant stroke, thus enabling stable and quantitative liquid dispensing with one hand and significantly reducing the fluctuation of liquid dispensing volume caused by sway.

[0006] As a further improvement to the above solution, four limiting holes are provided, and the four limiting holes are evenly distributed on the surface with respect to the center of the top of the limiting sleeve.

[0007] Through the above technical solution, the four centrally symmetrical limiting holes ensure that the limiting block is subjected to uniform force, eliminate lateral torque, and the sleeve remains straight even after long-term pressing, thus extending the pump head's lifespan.

[0008] As a further improvement to the above solution, the bottom of the pump head is located inside the positioning column.

[0009] With the above technical solution, the bottom of the pump head is always located inside the positioning column, forming a hidden internal guide to prevent dust from entering the friction surface and maintain smooth sliding.

[0010] As a further improvement to the above scheme, the number of the limiting blocks is set to four, and the four limiting blocks are evenly distributed symmetrically around the center of the bottom of the pump head.

[0011] Through the above technical solution, the four sets of limiting blocks correspond one-to-one with the limiting holes to form a four-point positioning. When pressed, the pump head is simultaneously subjected to force around it, which further suppresses swaying and improves the consistency of liquid output.

[0012] As a further improvement to the above solution, the limiting block passes through the limiting hole, and the collar is concentric with the limiting sleeve.

[0013] Through the above technical solution, the collar and the limiting sleeve are set concentrically to provide a second radial support for the pump head. The double concentric structure ensures that the compression path of the reset spring coincides with the pump body axis, reducing the risk of jamming.

[0014] As a further improvement to the above solution, the positioning post penetrates through the through hole.

[0015] Through the above technical solution, the positioning column penetrates the through hole, so that the limiting block is accurately guided throughout the entire lifting stroke. The pressing end position is unique, ensuring that the discharge volume is the same each time and realizing the quantitative function.

[0016] As a further improvement to the above solution, the pump head is provided with a liquid outlet, the bottle body is fixedly connected with a threaded strip, and the threaded strip is threadedly connected with a cap.

[0017] As a further improvement to the above solution, the threaded strip is located below the externally threaded tube.

[0018] With the above technical solution, the threaded strip is located below the external threaded tube and is independently equipped with a cap, which can lock the pump head during transportation or carrying to prevent accidental pressure; at the same time, the cap is screwed in the same direction as the bottle body thread, and can be opened and closed with one hand, taking into account both sealing and convenience.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This utility model forms a combined mechanism of axial guidance and radial limiting by setting a limiting sleeve, limiting hole, limiting block and positioning column. When pressed, the pump head can only move up and down vertically, which achieves the effects of anti-slip, anti-sway and stable liquid output.

[0020] This utility model features a quick spiral connection structure between an external threaded tube and an internal threaded tube, and an independently configured reusable cap below the pump head. During operation, the pump assembly can be disassembled and locked during transport, achieving convenient filling and recycling, and leak-proof carrying. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example: Please combine Figure 1-5 This embodiment of an emulsion bottle for easy dispensing via squeeze includes a bottle body 1. An externally threaded tube 2 is fixedly connected to the top of the bottle body 1. An internally threaded tube 3 is threadedly connected to the surface of the externally threaded tube 2. A conical platform 4 is fixedly connected to the top of the internally threaded tube 3. A limiting sleeve 5 is fixedly connected to the top of the conical platform 4. A limiting hole 6 is formed on the surface of the limiting sleeve 5. A positioning post 7 is fixedly connected inside the limiting hole 6. A pump body 8 is installed inside the conical platform 4. A pump head 9 is installed at the output end of the pump body 8. A limiting block 10 is fixedly connected to the surface of the pump head 9. A collar 11 is fixedly connected to the end of the limiting block 10 away from the pump head 9. A through hole 12 is formed at the top of the limiting block 10.

[0025] When in use, the limiting block 10 on the surface of the pump head 9 passes through the limiting hole 6, so that the pump head 9 can only move vertically during the pressing process, thus avoiding slippage when the pump head 9 is pressed, which would cause the pump head 9 to have unstable liquid output.

[0026] There are four limiting holes 6. The four limiting holes 6 are evenly distributed on the surface with the top center of the limiting sleeve 5 symmetrically. The four centrally symmetrical limiting holes 6 make the limiting block 10 evenly stressed, eliminate lateral torque, and the limiting sleeve 5 does not tilt after long-term pressing.

[0027] The bottom of the pump head 9 is located inside the positioning post 7. The bottom of the pump head 9 is always located inside the positioning post 7, forming a hidden internal guide to prevent dust from entering the friction surface and maintain smooth sliding.

[0028] There are four limit blocks 10. The four limit blocks 10 are symmetrically and evenly distributed around the bottom center of the pump head 9. The four sets of limit blocks 10 correspond one-to-one with the limit holes 6 to form a four-point positioning. When pressed, the pump head 9 is simultaneously subjected to force around its perimeter, further suppressing swaying.

[0029] The limiting block 10 passes through the limiting hole 6, and the collar 11 is concentric with the limiting sleeve 5. The concentric setting of the collar 11 and the limiting sleeve 5 provides a second radial support for the pump head 9. The double concentric structure ensures that the compression path of the reset spring coincides with the axis of the pump body 8, reducing the risk of jamming.

[0030] Positioning pin 7 penetrates through hole 12, so that the limiting block 10 is precisely guided throughout the entire lifting stroke, and the pressing end position is unique, ensuring that the discharge volume is the same each time, thus realizing the quantitative function.

[0031] The pump head 9 has a liquid outlet 13 on its surface, and a threaded strip 14 is fixedly connected to the surface of the bottle body 1. A cap 15 is threadedly connected to the surface of the threaded strip 14. The threaded strip 14 is located below the external threaded tube 2 and is independently equipped with a cap 15, which can lock the pump head 9 during transportation or carrying to prevent accidental pressure.

[0032] The threaded strip 14 is located below the externally threaded tube 2.

[0033] The implementation principle of a convenient squeeze-type quantitative emulsion bottle in this application embodiment is as follows: when using the emulsion bottle, press the pump head 9 so that the pump head 9 squeezes the pump body 8, drawing the emulsion inside the bottle body 1 into the pump head 9 and discharging it through the outlet 13.

[0034] When the pump head 9 is pressed, the limiting block 10 on the surface of the pump head 9 passes through the limiting hole 6, so that the pump head 9 can only move vertically during the pressing process, so as to avoid slippage when the pump head 9 is pressed, which would cause the pump head 9 to have unstable liquid output. The positioning post 7 passes through the through hole 12, so that when the limiting block 10 moves inside the limiting hole 6, the positioning post 7 limits the position of the limiting block 10.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
