摘要

The method for forming a container that comprises the following stages: the forming of the sidewall blank (O) from a blank by wrapping it into a form that is closed in its horizontal section and by seaming its opposite edges together; the sealing of the sidewall blank at one end with a lid member (P), which is equipped with a discharge hole (P1); the sealing of the sidewall blank at the other end with a bottom member (R); and the filling of the container. At first the lid member (P), the discharge hole (P1) of which is completely sealed with an openable closing member (P2), is inserted into the end of the sidewall blank (O). Thereafter the container is filled through the end of the sidewall blank (O) that was left open, and the container is sealed to form a tight container by sealing the end that was left open with the bottom member (R).
