Description

technical field [0001] The invention relates to an accessory of a container bottle, in particular to a bottle cap on a container bottle containing liquid. Background technique [0002] At present, the commonly used liquid bottle is generally composed of a bottle body, an upper cover and a lower cover, and one side of the upper cover and the lower cover is connected by an elastic strip, and the lower cover is fixed on the bottle body. In the liquid bottle industry, in order to ensure that the liquid in the bottle will not leak due to factors such as the transportation environment after being shipped out of the production workshop, a leak-proof device will be added. For example, a seal is added at the connection between the upper cover and the lower cover, or an aluminum foil seal is fixed at the mouth of the bottle. When consumers use it, they can use it by tearing off the seal or aluminum foil. However, for some daily necessities such as cosmetics, they are often used for ...

Problems solved by technology

However, for some daily necessities such as cosmetics, they are often used for a long time and the number of times they are used is relatively large, and they are often carried out for use. When carrying, these liquid bottles are not protected by seals and aluminum foil. The liquid in the bottle will leak out. If the road environment is bad, or if it is hit by other items, the upper cover and the lower cover will loosen, and a large amount of liquid in the bottle will leak out, which will not only waste, but also pollute other items carried.
