ABSTRACT:
This invention relates to a capsule which comprises a glass-shaped body with a funnel-shaped bottom having a central hollow extension which can be cut off, an upper closure baffle which can be pierced in order to introduce a diluent, a sealing disc comparatively flexible which is inserted into the glass-shaped body until the latter rests along a continuous supporting edge to ensure the seal by means of a slight forcing; and, below said supporting edge, projections contacting the disc and deforming it when this is thrusted beyond the supporting edge under an inner pressure allowing in this manner the liquid to flow out. This capsule is designed for preparing beverages.
