A method for forming the bottom (3) of a container (2) made of heat-weldable plastic material, including at least a body (4) and a stopper (5) removably associated to an end of the body (4), provides: to fill the container (2) through the bottom (3) open with a product to be packaged; to squeeze the body (4) in proximity of a remaining end thereof, carrying out a bottom portion (6); to heat the bottom portion (6) up to its melting; to compress said melted bottom portion (6) according to a direction nearly parallel to the longitudinal axis of the container (2); to release the body (4), at least in correspondence of the squeezing and the bottom portion (6). A container made of heat-weldable plastic material, including at least a body (4) and a stopper (5) removably associated to an end of the body (4), includes a bottom (3) sealed almost with a fin shape and having a shaped end bead (7) transversally positioned in comparison to the longitudinal axis of the container (2), in such way to constitute an abutment for the container (2). <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> |
