Coffee capsule

A capsule comprises a casing () that includes: a base wall () and a side wall () defining a cavity () that is suitable for containing a food preparation (P); a flange-shaped edge () extending from the side wall (), the side wall () being deformable along preset lines of pliability () to enable the casing () to be compressed along a direction (A) that is transverse to the base wall (). The capsule () further comprises: a cover element () fixed to the flange edge () to close the cavity () hermetically and a nozzle (), fixed to the cover element (), which is housed in the cavity (). The nozzle () comprises: a first end () and a second end () that are opposite; a first portion () that includes the first end (), is arranged for receiving injection means of fluid (F) and comprises a plurality of openings () for supplying the fluid (F) from the injection means to the cavity (); a second portion () that includes the second end (), extends through the outlet opening () and comprises a first tubular part () with a constant section, and a second part () that is shaped with respect to the first part (), in which the second portion () further comprises an outer flange () that peripherally surrounds the second end () and closes the outlet opening () when the capsule () is in a first, undeformed, configuration (K). The outer flange () of the nozzle () is configured for pushing the closing element () outwards to open the capsule (), when the capsule () is compressed to pass from the first configuration (K) to a second, deformed, configuration (J). Moreover, the second part () of the nozzle () is configured for projecting beyond the base wall () of the capsule () when the capsule () is further compressed passing from the second configuration (J) to a third' configuration (E), which is deformed further. In addition, the second part () of the nozzle () is shaped into a divergent form so as to guide outwards the food preparation (P) that exits the outlet opening () pushed by the pressurised fluid (F) when the capsule () is in the second configuration (J) or in the third configuration (E).

Capsule for beverages

A capsule for beverages includes a casing made by forming a sheet of thermoformable plastic material, the casing including: a base wall and a side wall defining a cavity suitable for containing an initial product to be combined with a fluid to obtain a final product in the form of a beverage, a first opening of the cavity opposite the base wall, an edge extending from the side wall and surrounding the first opening and a second opening made in the base wall. The first opening is closed hermetically by a cover element fixed to the edge, said the cover element being perforable by an injection arrangement of a dispensing machine in which the capsule is usable. The second opening is closed hermetically by a closing element) suitable for tearing when pressure inside the cavity exceeds a predetermined value. The capsule further includes a chamber placed opposite the base wall with respect to the cavity, the chamber being able to communicate with the cavity through the second opening, when the closing element tears, the chamber being provided with an outlet opening, made in the center of a bottom wall opposite the base wall. Inside the chamber a damping element is arranged that can communicate with the cavity through the second opening, when the closing element tears, the damping element being sized in such a manner as to prevent the occurrence of the water hammer phenomenon at the moment of tearing of the closing element, or at least to reduce considerably the intensity of the pressure waves generated by the phenomenon, the damping element acting also as a resting element for the closing element when the latter is deformed through the effect of a pressure increase inside the cavity.

A capsule for preparing a beverage includes a capsule body made by forming a sheet of thermoformable plastic material, the capsule body having: a base wall and a first portion of side wall defining a cavity suitable for containing an initial product to be combined with a fluid to obtain a final product in the form of a beverage, a first opening of the cavity opposite the base wall, an upper edge extending from the first portion of side wall and surrounding the first opening, a second opening of the cavity made in the base wall, in which the first opening is closed hermetically by a covering element fixed to the edge, the covering element being perforable by a dispensing machine in which the capsule is usable, in which the second opening is closed hermetically by a closing element that is suitable for tearing when pressure inside the cavity exceeds a preset value, the capsule further comprising a chamber located opposite the base wall with respect to the cavity and defined by a second portion of side wall and by a bottom wall of the body of the capsule, the chamber being able to communicate with the cavity through the second opening, when the closing element tears, the chamber being provided with a third opening, made in the center of the bottom wall, inside the chamber there being arranged a damping element for controlling the exit speed of the beverage, the damping element is configured in such a way as to move inside the chamber between an initial position and a final position, through the effect of the pressure of the beverage in the chamber.

A capsule includes a first container provided with a first closed cavity containing a first product and a second container provided with a second closed cavity containing a second product. The first container and the second container include a first interface element facing the first cavity and a second interface element facing the second cavity, respectively. The first interface element is provided with a first connecting device having a first conduit and the second interface element is provided with a second connecting device having a second conduit. In an assembled configuration of the capsule, in which the first container is associated with the second container, the first connecting device is engaged with the second connecting device so as to couple the first conduit with the second conduit to make a flow connection between the first cavity and the second cavity and enable at least the first product to pass into the second cavity and join the second product to make a final product.

Capsule and dispensing machine for beverages

A capsule includes a deformable and/or compressible casing, provided with a base wall and a side wall defining a cavity that is open and suitable for containing an initial product to obtain a final food product. A supporting element is fixed to a first edge of the casing and facing the cavity and a nozzle is fixed to the supporting element and arranged for delivering a fluid into the cavity which interacts with the initial product to make the final product. The nozzle also opens the base wall and enables the final product to exit when the casing is compressed and crushed.
