Abstract
A method for applying a sealing member to a capsule intended for the preparation of a beverage in a device for making beverages, where the capsule includes a body having a bottom wall, a side wall and a flange-like rim which extends from the side wall, comprises a step of applying a charge of sealing composition in a viscous state on the flange-like rim and a step of compression moulding the charge of sealing composition against the flange-like rim.
Claims18
An apparatus for applying a sealing member to a capsule intended for the preparation of a beverage in a device for making beverages, where the capsule includes a body having a bottom wall, a side wall and a flange-like rim which extends from the side wall, wherein the apparatus comprises:
- a metering device configured to deliver a charge of sealing composition in a viscous state onto the flange-like rim of the capsule;
- and
- a compression moulding device, provided with a mould forming a shaping cavity which is geometrically shaped to at least partly surround the flange-like rim of the capsule with an uninterrupted inner annular portion of the shaping cavity to compress the charge of sealing composition against the flange-like rim in the shaping cavity,
- wherein the flange-like rim has a rear face, directed towards the bottom wall of the body, and a front face, opposite to the rear face, and wherein the charge is applied by placing the charge itself on the front face of the flange-like rim and wherein, during the compression moulding, the compression moulding device is configured to migrate the sealing composition making up the charge around an end edge of the flange-like rim so as to adhere to the rear face of the flange-like rim.
