Abstract:
An apparatus for applying a cellulose-based annular body to a perimeter flange of a container includes a supporting unit and an operating unit. The supporting unit has a seat to receive a body of the container and is surrounded by an annular portion on which the annular body and the flange rest, such that the annular body is interposed between the annular portion and the flange. A heating device heat the annular body. The supporting unit includes an annular recess, surrounding the annular portion, to at least partly house an annular end bead of the flange. The apparatus includes a forming device, movable along a respective axis of movement between a far position and an engaging position. In the engaging position, the forming device engages and deforms the annular bead pushing said annular bead into the annular recess.
Abstract:
An apparatus for cutting off and joining a sheet element to a container includes an operating unit including a cutting device with a cutting edge surrounding a joining device. The operating unit and the container are movable with respect to one another along a movement axis between a spaced condition, in which a sheet material is interposed therebetween and is spaced therefrom, and a joined condition, in which the joining device joins the material to the container. A retaining device retains the material during joining and cutting. In the joined condition, the cutting device remains fixed relative to the joining device and the retaining device moves along the axis from tensioning to cutting positions, the sheet element being cut on the cutting edge from the material during movement of the retaining device from the tensioning to the cutting positions.
Abstract:
A capsule for beverages with a casing which includes a base wall and a side wall defining a cavity for combining an initial product and a fluid to obtain an end product, and an edge extending from the side wall. The capsule includes a covering element fixed to the edge to close the cavity hermetically, which is pierceable by an extracting element of a dispensing machine. The casing is made by forming a sheet of thermoformable plastics. The edge includes a sealing element with a protrusion facing the base wall that is obtainable by the sheet forming a further cavity suitable for containing a fluid. The covering element is fixed to also seal hermetically the further cavity to create a cushion that is deformable between the edge and the covering element that defines the sealing element arranged for sealingly engaging, when compressed, with an abutting element of a dispensing machine.
Abstract:
A dispensing machine includes an injector for supplying water under pressure to a capsule housed in a housing A dispensing device closes the housing, which includes an annular sealing edge for contacting the capsule in the closed configuration.The capsule includes a casing with base and side walls defining a cavity containing a product to be added to water for obtaining a beverage. A flanged edge extends from the side wall. A covering element closes the cavity. A sealing element, associated with the flanged edge creates a fluidic seal with the sealing edge in the closed configuration. The sealing edge includes radial open grooves and radial crests which contact a sealing area of the annular body. The grooves and crests penetrate more deeply into the sealing area during dispensing, to improve the fluidic seal, when the annular body is softened by contact with injected water.
Abstract:
A capsule includes a casing having an axis of extension, the casing including a base wall and a lateral wall defining a cavity for containing an initial product. A closing element is fixed to the base wall for perforation by a blade of a fluid injection device The base wall includes an annular edge region extending to the lateral wall, a central region, and a groove, interposed between the central and edge regions, and shaped to receive the blades. The closing element has a central portion fixed to the central region and an edge portion fixed to the edge region. The central region and the edge region extend on respective planes which are offset from each other along the axis such that an intermediate portion of the closing element, interposed between the central portion and the edge portion for closing the groove, is inclined.
