Description

Technical Field

[0001] This utility model relates to the field of perfume dispensing technology, specifically a leak-proof and sealed portable perfume dispensing bottle. Background Technology

[0002] Perfume portable dispensers are miniature containers used to store and carry small amounts of perfume. They are typically designed to be small, lightweight, and easy to carry, meeting the needs of individuals to dispense and use perfume in different occasions. Their core function is to prevent liquid leakage through a sealed structure, while also taking into account safety, durability, and convenience.

[0003] In existing technologies, portable perfume dispensing bottles generally suffer from problems such as simple sealing structures and insufficient leak-proof performance. Traditional dispensing bottles mostly rely on corks or simple threaded connections to achieve sealing. When the bottle is inverted or subjected to external pressure, the seal is prone to failure, leading to liquid leakage. In addition, the glass bottle is directly exposed to the outside, making it prone to breakage due to collisions during transportation or daily use. Furthermore, it lacks an effective cushioning structure. Although some products are equipped with dust caps, the nozzle is easily contaminated by accidental contact, and cleaning and maintenance are difficult. At the same time, the design of the liquid filling port of existing dispensing bottles has obvious defects: most products do not have a filter device, allowing external impurities to easily enter the bottle and contaminate the liquid; some products use complex snap-lock sealing structures, which are inefficient to disassemble and are prone to wear.

[0004] Therefore, it is necessary to propose a leak-proof and sealed portable perfume dispensing bottle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a leak-proof and sealed portable perfume dispensing bottle that features nozzle contamination prevention, quick disassembly and assembly, and one-handed operation, thus solving the problems mentioned in the background technology.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4As shown, a leak-proof and sealed portable perfume dispenser includes a sealing main component 100, a protective cap 200, a protective plastic shell 300, and a glass bottle 400. A suction mechanism 101 is fixedly installed inside the sealing main component 100. A nozzle 103 is fixedly connected to the top of the suction mechanism 101, and a suction tube 102 is fixedly connected to the bottom of the suction mechanism 101. The suction tube 102 is located inside the glass bottle 400, which is located at the bottom of the sealing main component 100. The protective plastic shell 300 is fitted onto the surface of the protective plastic shell 300. The protective cap 200 is rotatably fitted onto the surface of the nozzle 103. An inlet 401 is provided at the bottom of the glass bottle 400. The sealing main component 100 achieves unidirectional liquid flow control through the built-in suction mechanism 101, forming a double leak-proof structure. The protective cap 200 and the nozzle 103 adopt a rotating sleeve design, which facilitates the isolation of external contamination during sealed storage. The protective plastic shell 300 is installed in a wrap-around manner to enhance the overall structural stability and reduce the risk of collision during transportation. The bottom of the glass bottle 400 is provided with an inlet 401 to achieve safe liquid injection operation and avoid direct contact with the glass surface.

[0028] In a further preferred embodiment, an internally threaded cylinder 107 is fixedly connected to the inner top wall of the sealing main component 100, and a sealing rubber ring 106 is fixedly connected to the surface of the suction mechanism 101. The top of the glass bottle 400 is threadedly connected to the internally threaded cylinder 107, and the sealing rubber ring 106 is tightly fitted to the inner wall of the top opening of the glass bottle 400. The threaded engagement between the internally threaded cylinder 107 and the glass bottle 400 enables quick assembly and disassembly, improving ease of use. The sealing rubber ring 106 forms a dynamic sealing layer at the threaded connection, effectively compensating for assembly tolerances and preventing leakage.

[0029] In a further preferred embodiment, a filter plate 402 is fixedly connected to the top of the inlet 401, and a sealing plug 500 is threadedly connected to the inside of the inlet 401. A sealing rubber ring 501 is fitted onto the upper surface of the sealing plug 500, and the sealing rubber ring 501 fits tightly against the inner wall of the inlet 401. The filter plate 402 intercepts impurities in the inlet 401, ensuring the purity of the injected liquid. The sealing plug 500 and the sealing rubber ring 501 form a double-layer sealing structure, enhancing the sealing performance during storage.

[0030] In a further preferred embodiment, a shock-absorbing rib 301 is fixedly connected to the inner wall of the protective plastic shell 300. The side of the shock-absorbing rib 301 is in contact with the surface of the glass bottle 400, and a gap exists between the glass bottle 400 and the protective plastic shell 300. The shock-absorbing rib 301 forms a non-contact buffer layer inside the protective plastic shell 300 to prevent the glass bottle 400 from breaking due to drop impact. The gap between the protective plastic shell 300 and the glass bottle 400 is designed to accommodate volume expansion caused by temperature changes.

[0031] In a further preferred embodiment, a rod 105 is fixedly connected to the top of the sealing main component 100, and a slot 104 is provided at the bottom of the nozzle 103.

The sliding insertion structure between the rod 105 and the slot 104 ensures the stable installation of the nozzle 103 and prevents leakage caused by loosening during use.

[0032] Preferably, the protective cap 200 has a slot 201 on its side wall, which corresponds to the position of the nozzle on the spray head 103. The corresponding design of the slot 201 and the nozzle enables precise positioning, facilitates one-handed operation while keeping the nozzle clean, and the rotation locking mechanism of the protective cap 200 prevents accidental opening, enhancing the reliability of transportation and storage.

[0033] In a further preferred embodiment, a limiting top strip 108 is fixedly connected to the side of the sealing main component 100. The limiting top strip 108 matches the model and specifications of the slot 201. An anti-slip ring 109 is fixedly connected to the side of the sealing main component 100. The cooperation between the limiting top strip 108 and the slot 201 forms an anti-accidental contact structure, preventing the protective cap 200 from accidentally falling off during daily carrying. The anti-slip ring 109 increases hand friction and improves grip stability under different hand conditions.
