Abstract
Packaging of ground coffee in the form of pastille, "dosette" or predosed bag (1) usable in espresso coffee machines, the pastille, the "dosette" or the predosed bag (1) being formed of filter-paper (3) which encloses the ground coffee (4). The ground coffee content (4) placed in the pastille or the like is partially or totally circumscribed at its periphery, by at least one piece (6) of a sufficiently rigid material acting as a frame, so that the pastille or the like (1) has a good mechanical behaviour. Application to the production of coffees.

Package of ground coffee, comprising:
- a prefilled bag having a central axis and including a first concave filter portion having a first peripheral edge which extends circumferentially relative to said central axis and a first flange extending from said first peripheral edge radially outward relative to said central axis, and a second concave filter portion having a second peripheral edge which extends circumferentially relative to said central axis and a second flange extending from said second peripheral edge radially outward relative to said central axis, an inner surface of said first concave portion facing an opposing inner surface of said second concave portion to provide a cavity therebetween structured and configured for the containment of coffee, said first flange abutting said second flange in a plane which extends in a transverse direction relative to said central axis and which bisects said cavity into two substantially equal parts, and an annular reinforcement member which abuts at least one of said first flange and said second flange, said annular reinforcement member being sufficiently rigid to serve as a framework such that said prefilled bag has sufficient mechanical strength to be usable in an espresso coffee maker.
Espresso coffee machine for use with a package of ground coffee, said espresso machine extending in a longitudinal direction and comprising:
- a water heater having inlet means for water;
- an assembly operatively associated with said water heater and including an outlet for coffee, and a cylinder enclosing a piston adapted to move in said longitudinal direction;
- means for introducing a package of ground coffee in a vertical plane transverse to the longitudinal direction and between the water heater and the assembly;
- said water heater having abutments disposed at one end thereof in a position perpendicular to said longitudinal direction, said abutments including means for receiving a rigid edge of the coffee package, said assembly including means for coacting with said water heater at said abutments to secure in position the coffee package by its rigid edge between the abutments.
