Description

[0002] Packing bottle, as the main container of liquid, milk body and other fluid substances, is widely used in food, cosmetics, medicine and other fields. Its design not only concerns the storage and transportation safety of products, but also directly affects the use experience of consumers. Traditional packing bottles mostly adopt simple screw cover or press type nozzle design. These designs meet the basic sealing and use requirements to a certain extent, but still have deficiencies in some specific scenarios.

[0003] In the existing packing bottle technology, a significant problem is the insufficient sealing performance. Especially when the pressure in the bottle increases (such as due to temperature change, collision during transportation, etc.), the traditional sealing structure often cannot effectively resist the pressure, leading to leakage problems. This not only may damage the product, but also may cause inconvenience to consumers, and even cause safety hazards.

[0004] In addition, the existing packing bottle often lacks the function of limiting the amount of fluid substance when taking. Whether it is directly poured through the screw cover or sprayed through the press type nozzle, it is difficult to accurately control the amount taken.
