Abstract:
1. Capsule injection moulded or thermoformed for obtaining a beverage from products placed therein, the capsule comprising an internal outflow duct comprising an internal through hole for an outflow of the infusion beverage through the internal through hole from the capsule and a differentially attached sealing element, the capsule comprising an upper surface having a closed perimeter for supporting said differentially attached sealing element so as to hermetically seal the capsule by means of said differentially attached sealing element, wherein a top of said internal outflow duct is substantially on the same level as said upper surface of the capsule and placed within the closed perimeter of the upper surface of the capsule so that said top supports said differentially attached sealing element when the capsule is sealed so as to seal said internal through hole and said differentially attached sealing element is welded to said upper surface of the capsule and said top of said internal outflow duct with differential detachment welding, wherein said differential detachment welding allows for lifting of said differential attached sealing element from said top of the internal outflow duct opening the internal through hole and at the same time keeping said differentially attached sealing element fixed to the closed perimeter of the upper surface of the capsule, whereby by injecting water under pressure into the capsule, said differentially attached sealing element is lifted becoming detached from the top of the internal outflow duct, opening said internal through hole of said internal outflow duct so that the beverage flows outwards through said internal through hole and said differentially attached sealing element remains welded to the closed perimeter of said upper surface.
