点があった。2. Description of the Related Art Conventionally, as a metal tube for preventing the contents from dripping, for example, there is one as shown in FIG. Generally, in the case of a metal tube made of a metal such as aluminum, when the body of the tube is pressed in order to pour out a certain amount of contents (such as adhesive), press the body once. When deformed, in order to maintain the state of the body as it is, even after a certain amount of content is poured out from the mouth, it is continuously poured out from the mouth. Then, a phenomenon occurs in which the contents drip at the mouth. In particular, when the body portion is largely deformed by an excessive pressing force by mistake, there is a disadvantage that a necessary amount of content is instantaneously poured out from the mouth portion.
