Prepackaged charge of edible material powder, and beverage preparation system using said charge

A beverage preparation system comprising a prepackaged charge (10′) of powder of edible material, and an infusion assembly (1, 2) adapted to cooperate with said prepackaged charge, wherein said prepackaged charge is a prepackaged charge of edible material powder for use in a beverage preparation system, comprising a rigid container body (10) made of paper or cardboard, comprising a continuous side wall (11, 11′) and a bottom wall (12, 12′) made integral with each other, obtained by processing vegetable fiber pulp derived from waste from the primary processing of seasonal crops such as sugarcane, rice, cotton, hemp, sorghum, bamboo or the like, alone or in composition with each other, in which the Kappa number of the vegetable fiber pulp is less than 2, and in which the walls of said container body are made in such a way that at least one face (11, 12′) of said walls is continuous and compact, while the other face (12) is discontinuous and wrinkled, and are able of acting as a filter during use, allowing the passage of infusion, and wherein said infusion assembly (1, 2) comprises an infusion chamber (101) whose bottom wall (111;

• 161) is provided with a plurality of conduits (131;
• 181) communicating with the dispensing means (201), each of said conduits (131;
• 181) being positioned at a relief or recess (121;
• 171) capable of causing a plastic deformation (12″) in the bottom wall (12, 12′) of the container body (10) of the prepackaged charge without causing a break of said wall, thereby allowing the flow of infused beverage to pass through said wall, which acts in this way as a filter.
