Abstract: A coffee pod which can be used for machines for preparing and dispensing coffee beverages that comprise at least one extraction chamber, and at least one piston for compacting a predetermined amount of ground coffee inserted into the extraction chamber. The pod includes: a predetermined amount of ground coffee compacted into an aggregate of ground coffee beans, having an outer shape suitable for rolling, and preferably a substantially spherical ball shape; and a filter casing formed of at least one pervious, microporous or microperforated sheet or film, trapping and matching the shape of the compacted coffee aggregate. The sheet or film is flexible, having stretchability properties with an elongation at rupture of at least 30% and an ultimate tensile strength of less than 2,000 N/m, and a thickness of at least 150 ?m.

Abstract: The invention relates to a stopper capsule, having an axial direction, including a shell, with a head, a skirt, and a joint, where a) the joint is a form joint, b) the form joint has b1) a resilient layer, a set of adjacent layers, b2.1) a barrier layer, b2.2) a malleable support layer with the function of providing the set of adjacent layers a global malleable property such that the joint can be shaped without creation of folds, b2.3) an outer layer having an outer surface which can be compressed by the axial compression resulting from stoppering such as to match the form of the mouth of the neck. The invention further relates to a method of production of the capsule and a method of stoppering.

Abstract: The method comprises a) an extrusion stage wherein a extruded tube made of a thermoplastic material is formed by extrusion with the aid of an extrusion die having a diameter D0, a slit width E0 and a section S0; b) a stage wherein the extruded tube is radially expanded in order to form a radially expanded tube having a diameter D2, a thickness E2 and corresponding section of area S1; c) a truncating stage wherein the expanded tube is broken down into tube portions; d) a stage in which the tube portions are formed in such a way that a heat-shrinkable cap is obtained and in which an axial drawing stage is incorporated, between extrusion stage a) and expansion stage b), at the output of the extrusion die, in order to obtain an axially drawn tube having a diameter D1 which is typically smaller than D0 and D2, and a thickness E1 which is typically lower than E0, such that S0/S1 typically ranges between 2 and 10.

Abstract: A method for crowning a container neck, such as a bottle, by securing or crimping a cap provided with a skirt on the neck, the neck including a glass ring with a lower shoulder, including the steps of a) crimping the cap to the neck, so as to form a swaged portion of the skirt; b) marking the swaged portion of the skirt with an etching device, to form an etching on the swaged portion based on an etching pattern. The visual mark reduces the mechanical properties of the swaged portion, so as to prevent any fraudulent attempt to uncrimp the cap from the neck or any recycling of the bottle.

Abstract: An extensional flow mixer especially for viscous liquids has a housing with an end inlet connectable to a pressurized source of the liquids, and an outlet at an opposite end of the housing. A mandrel located in the cavity has protrusions with sloping side surfaces, the outer edges of which cooperate with the internal surface of the cavity to divide the cavity into a series of chambers separated by slits, such that liquid passes successively through all the chambers and slits in moving from the inlet to the outlet. The slits have cross-sectional areas which decrease in the liquid flow direction. The mandrel sides have helical grooves forming passageways with the housing wall which allow liquid to be distributed evenly around the edges of the mandrel to the inlet end or upstream chamber. The mandrel may rotate to provide additional shear mixing.

Abstract: An extension flow mixer especially for viscous liquids has a housing (10) with an end inlet (12a, 14a) connectable to a pressurized source of the liquid, and an outlet (119) at an opposite end of the housing (10). A mandrel (30) located in the cavity has protrusions (20′, 32′) with sloping side surface, the outer edges of which cooperate with the internal surface (114a) of the cavity to divide the cavity into a series of chambers separated by slits, such that liquid passes successively through all the chambers and slits in moving from the inlet (12a, 14a) to the outlet (119). The slits have cross-sectional areas which decrease in the liquid flow direction. The mandrel (30) sides have helical grooves (134) forming passageways with the housing wall (114a) which allow liquid to be distributed evenly around the edges of the mandrel (30) to the inlet end or upstream chamber. The mandrel (30) may rotate to provide additional shear mixing.
