Abstract
A method for manufacturing a plurality of containers from a tube of flexible packaging material includes transversely severing the tube into a plurality of individual containers, each having a main body with two opposed pointed lower corners, pinching each pointed lower corner to collapse the corner into a flattened triangular shape while adding heat to the same in order to well the corner together in the flattened condition, and bending each flattened corner to lie under its respective main body, while the flattened corner still retains heat.
Claims11
A method of manufacturing a plurality of containers from a tube of flexible packaging material, the method comprising the steps:
- transversely sealing and severing the tube into a plurality of individual containers each having a main body with two opposed pointed lower corners;
- pinching each pointed lower corner to collapse the corner into a flattened triangular shape while adding heat to the same in order to weld the corner together in the flattened condition;
- and
- bending each flattened corner to lie under the main body of its respective container, while the flattened corner still retains heat and holding said flattened corner beneath the main body until it cools so that the flattened corner remains beneath the main body.
A method for the manufacture of a container possessing a main body with a pair of lower pointed corners to make the container self-supporting, the method comprising the steps:
- pinching the pointed lower corners to collapse each corner into a flattened triangular shape while adding heat to the same in order to weld the corner together in the flattened condition;
- and
- bending the flattened corners to lie under the main body, while the flattened corners still retain heat and holding said flattened corners beneath the main body until they cool so that the flattened corners remain beneath the main body.
An apparatus for the manufacture of a container possessing a main body with a pair of opposed lower pointed corners to make the container self-supporting, the apparatus comprising:
- pinching means for pinching the pointed lower corners to collapse each corner into a flattened triangular shape;
- heating means for adding heat to the collapsed corners in order to weld each corner together in a flattened condition;
- and
- bending means for bending each flattened corner to lie under the main body, while the flattened corner still retains heat and holding the flattened corner beneath the main body until it cools to that the flattened corner remains beneath the main body.
A method of forming a self-supporting fluid-filled container having a body with an internal reservoir filled with fluid and a narrow spout in fluid communication with said body, said body having two opposed pointed lower corners, said method comprising the steps of:
- pinching each pointed lower corner to collapse each corner into a flattened portion;
- heat sealing each flattened portion to weld each flattened portion in the flattened condition;
- and
- folding each flattened portion underneath the body while each flattened portion still retains heat from the heat sealing so that each flattened portion remains beneath the body when each flattened portion cools.
An apparatus for forming a self-supporting fluid-filled container having a main body with a pair of opposed lower pointed corners, the apparatus comprising:
- a pinching mechanism to contact and pinch each lower corner and collapse each corner into a flattened condition;
- a heat sealing mechanism energizeable to heat seal each flattened corner to weld each flattened corner in a flattened condition;
- a corner folding mechanism downstream of said heat sealing mechanism, said corner folding mechanism being actuable to contact each flattened corner while the flattened corner retains heat and fold the flattened corner beneath the main body after it cools;
- and
- a drive to advance the container from the heat sealing mechanism to the corner folding mechanism.
