Cartridge for preparing a liquid product

摘要

A cartridge (10) for preparing a liquid product, for example a beverage such as coffee by introducing liquid and/or steam into the cartridge (10) contains a dose (12) of at least one substance, such as for example powdered coffee, which is able to form the aforesaid product using said liquid and/or steam. The dose is enclosed between foils (14, 16) that can be traversed by the aforesaid liquid and/or steam, said foils (14, 16) being connected together around the dose (12). The aforesaid foils (14, 16) are made of compostable material, i.e., a material that can be recovered by composting and biodegradation, and are connected together around the dose (12) using a connecting material (30), which is also compostable. The cartridge as a whole can hence be recovered by composting and biodegradation, in compliance with the European Norm UNI EN 13432:2002 and/or subsequent modifications and integrations thereof.

1. A cartridge for preparing a liquid product by means of liquid and/or steam introduced into the cartridge, the cartridge comprises:
a filling, two foils, wherein the filling contains at least one substance for preparing said product by means of said liquid and/or steam included between the two foils to be traversed by said liquid and/or steam, said two foils being mutually connected around said filling, wherein: the two foils are of a compostable material, and the two foils are mutually connected around said filling by means of a connection material which is compostable, wherein the connection material is a thermo-fusible material that is adapted to pass to a fluid state or a semi-fluid state upon reaching a given softening temperature, wherein the two foils are made of a porous material, which has a porosity, wherein the connection material penetrates the porosity of the two foils' porous material, wherein the connection material has a melting point, and the two foils have a melting point that is different than the melting point of the connection material.
