Description

Technical Field

[0001] This utility model relates to the field of aromatherapy bottle caps, and in particular to a durable aromatherapy bottle cap. Background Technology

[0002] Bottle caps are widely used in bottled products because they keep the contents sealed and provide anti-theft and security features. As such, they are a key product in bottled packaging and are an upstream industry for the food, beverage, wine, chemical, and pharmaceutical industries. Early bottle cap development involved cork, tin crown caps, and screw caps. Today, continuous development has led to the creation of aluminum long-neck caps, aluminum caps for carbonated drinks, hot-fill aluminum caps, aluminum caps for injection solutions, medicine caps, flip-top ring caps, safety claw caps, and plastic bottle caps.

[0003] Aromatherapy devices consist of an aromatherapy bottle and an aromatherapy bottle cap. The aromatherapy bottle contains aromatherapy liquid, and the aromatherapy bottle cap has a vent for the aromatherapy liquid to evaporate. Usually, the bottle opening is fitted with a sealing film to prevent the aromatherapy liquid from leaking out of the vent during transportation. The sealing film can be removed before use. However, this type of aromatherapy bottle cap cannot completely seal the aromatherapy bottle, causing the aromatherapy liquid to remain in an evaporating state, which can easily lead to waste. Furthermore, if the aromatherapy bottle is bumped, the aromatherapy liquid may leak out of the vent, causing inconvenience for use.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0005] In view of the above, this utility model addresses the deficiencies of the existing technology, and its main objective is to provide a durable aromatherapy bottle cap. By providing a sealing gasket at the top of the internal thread, the aromatherapy liquid inside the bottle will not leak out from the threaded connection when the bottom cap is closed on the aromatherapy bottle, thus improving the sealing performance of the bottle cap. Furthermore, the bottom cap has multiple first vents and a waterproof and breathable membrane covering the first vents, ensuring that the aromatherapy liquid can evaporate from the first vents while preventing leakage. In conjunction with a top cap that can selectively cover multiple first vents or open at least one first vent, the top cap can seal the aromatherapy bottle when the aromatherapy is not in use, making the aromatherapy liquid more durable. The ingenious structural design and reinforced structure improve the structural strength of the top and bottom caps, making them less susceptible to impacts and scratches, further enhancing the durability of the aromatherapy bottle cap. Simultaneously, it provides friction for rotating the top and bottom caps, facilitating their rotation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
