Abstract: A method is described for joining a first sheet and a second sheet of packaging material, which includes: preparing the first sheet with a first joint edge transverse to a longitudinal axis of the first sheet, and having a particular configuration with a non-straight edge; arranging the second sheet with a second joint edge transverse to a longitudinal axis of the second sheet; superimposing the first and second joint edges to join the first and second sheets so that the longitudinal axes are aligned, and the second sheet constitutes a continuation of the first sheet along the longitudinal axes; welding together the first and second joint edges superimposed on each other.

Abstract: A container management system including a lid assembly configured to engage/disengage a collar of a container to close and open an aperture thereof, wherein the lid assembly includes an interior lid compartment in communication with an interior portion of the container when the lid assembly engages the collar, a reactive substance configured to undergo a physical change in response to a change of an environment condition at the aperture when the lid assembly engages the collar. The physical change of the reactive substance turns the lid assembly from a first operative condition wherein the lid assembly can be disengaged from the collar to open the aperture to a second operative condition wherein a portion of the lid assembly cannot be disengaged from the collar and closes the aperture.
