The bottle and can are substantially identical in structure, and the following description refers to the bottle. Taking operation steps of a traditional bottle: holding the bottle body with one hand, unscrewing the bottle cap with the other hand, and putting down the bottle cap. The common spoon or quantitative spoon is generally used for scooping the articles in the bottle by extending into the bottle mouth. Then put down the ladle, hold the body of bottle with one hand again, the lid is covered to one hand, and whole process needs both hands to operate. The situation of manual and manual mess often occurs when a plurality of bottles are opened and the articles in the bottles are taken out simultaneously. A plurality of spoons sometimes need to be cleaned and stored, and are not favorable for users to carry outside. In addition, some seasoning bottles exist in the current market, and the bottle cap is provided with a spoon, so that the trouble of finding the spoon is avoided. However, when the bottle is filled with dense granular articles and is full, the spoon on the bottle cap is inserted into the bottom of the bottle, which is hard, and the bottle cap is easy to be not closed and cannot be sealed. Moreover, the length of the spoon on the bottle cap is a certain distance away from the bottle bottom, so that when the amount of articles at the bottle bottom is small, the bottle is inconvenient to ladle and is very laborious to take.
