Method for manufacturing containers and apparatus

A method of manufacturing filled containers comprising the steps of

• providing at least a first and a second part of the container;
• providing a product within at least one of said first and said second parts;
• assembling said first and said second part by bonding a portion of said first part to a portion of said second part, thereby generating a bond area;
• scanning said bond area with a transmitted beam of ultrasonic energy;
• sensing reflected ultrasonic energy from said bond area;
• generating from said sensed ultrasonic energy a signal indicative of quality of said bond along said bond area, thereby
• leading said ultrasonic energy from a mechanical output of an electric to mechanical converter to generate said transmitted beam and onto said bond area and said reflected ultrasonic energy from said bond area towards and onto a mechanical input of a mechanical to electrical converter for sensing said reflected ultrasonic energy in a liquid.

• directing said beam of ultrasonic energy in a direction towards and onto said bond area which is different from perpendicularly thereto considered in a plane defined by a perpendicular line on said area and scanning direction of said beam along said bond area.
