Abstract
A tubular body provided with a first end wall is filled through the open end thereof and sealed by a second end wall. One of these walls has a hole therethrough closed by a closing means, this wall being initially of generally concave configuration with the closing means disposed entirely inwardly of a plane passing through the rim of the wall. The concave wall is subsequently changed to a generally convex configuration with the closing means disposed at least partially outwardly of the plane.
Claims19
The method of making a filled container which comprises the steps of providing a container having an open end and an opposite end provided with an end wall of generally concave shape having an opening therein, closing the opening in said end wall, filling the container through the open end thereof with filling material while maintaining said end wall in generally concave shape, sealing the open end of the container to confine the filling material therein, and then causing said end wall to change from a generally concave shape to a generally convex shape.
The method of making a filled container which comprises the steps of forming a tubular container having an open end and an opposite end closed by a first end wall which is of generally concave configuration and which has a circumferential rim and a pouring hole therein, closing said pouring hole with a closing means and maintaining the closing means in such a position that the closing means is disposed entirely inwardly towards the center of the container with respect to a plane passing through said circumferential rim, filling the container with filling material through the open end of said container while maintaining said first end wall in generally concave configuration and said closing means in said position, sealing the open end of the container with a second end wall to seal the filling material within the container, and then causing said first end wall to be changed from a generally concave configuration to a generally convex configuration and moving said closing means at least partially outwardly of said plane.
