Abstract: A plastic material container, e.g. a beverage bottle, having a neck which requires the use of a smaller amount of plastic than the bottle necks of the prior art, and which is able to ensure a complete functionality for coupling the cap, ensuring at the same time the possibility of implementing the traditional supporting; sealing and handling operations of the bottle carried out during the various steps of manufacturing the same.

Abstract: A bottle base made of plastic material, particularly for beverages, of the type which has, on its bottom, reinforcement recesses. The reinforcement recesses comprise a recess which runs along a transverse reference dimension of the base; the recess forms a main rib inside the base.

Abstract: A carrier for biofilm to be used in wastewater purification plants, comprising a cup-shaped body that is formed by a substantially circular bottom, by a perimetric wall that has substantially a cylindrical symmetry and by an opening that is arranged opposite the bottom for the access of the wastewater; a helical wing runs along the inner side of the perimetric wall and accordingly has a portion of surface that is undercut with respect to the opening. Advantageously, the carrier is constituted by an ordinary screw cap for bottles, which is made of plastics, or by a reject from the production of screw caps for bottles.

Abstract: An aseptic closure for containers of liquids comprising a main body provided with a threaded ring, which is designed to be associated with a neck of a container and from which there protrudes a tubular projection which is coupled to an upper closure. A step protrudes from the inside wall of the projection, proximate to the main body, and forms a passage hole which is controlled by a flow control element which is monolithic, by means of radial supporting bridges, with respect to the upper closure; the upper closure has a tubular structure and can slide axially along the projection from a lowered position, which closes the hole because the flow control element forms a seal against its wall, to a raised position for opening the hole for the passage of the liquid.
