ABSTRACT:
In a process for making a filled and closed container of heat-sealable plastic hose, in one work operation, the hose is expanded to become a container body, the body is filled and the upper part of the container is shaped when the container is closed. After the filling process and before closing, the upper part of the container is closed by a rubber stopper. An apparatus to carry out the process includes a container-molding appliance having a lower and upper mold parts, with a mold holding fixture in each of the upper parts which can be displaced in the direction of movement of the upper mold part and be moved automatically opposite the upper mold part, and with a holding device inside the plastic hose which can be moved vertically. The holding device releasably holds the rubber stopper for insertion into the completed container body. The holding device is attached to a cross slide which permits horizontal movement, so that the rubber stopper can be moved from a receiving location to the container being formed.
