Abstract: A dosing cap (1) for powders or liquids including an outer body (2) designed to be inserted into the neck of the container to which the cap (1) is applied and an inner body (3) of a substantially cylindrical shape, which contains the powder or liquid, is mobile inside the outer body (2), and is designed to break the sealing membrane (5) of the dosing cap (1) in response to an axial pressure exerted on its top part. Housed in the inner body (3) is a body (4), preferably cylindrical in shape, which is adjacent to the internal surface of the inner body (1) and is designed to break the sealing membrane (5) of the dosing cap (1) in response to an axial pressure exerted on its top part. Preferably the body (4) is fixed to the sealing membrane (5) of the dosing cap (1).

Abstract: A standardised modular system (100) for moulds of injection moulding machines comprises an injection assembly (1), an ejection assembly (5), a mould (2) comprising a fixed mould half (3) associated with the injection assembly and a movable mould half (4) associated with the ejection assembly (5) and movable from a mould closed position to a mould open position, male and female mould inserts (32, 42) mounted removably in special seats provided respectively in a female mould plate (30) and a male mould plate (40) of the fixed mould half and movable so as to be modularly composable and decomposable according to the item to be moulded, first adapter means (8) disposed interchangeably between the injector assembly (1) and the fixed mould half (3) so as to allow the arrangement of the injectors (16) of the injection assembly to be varied, and second adapter means (56, 66, 67, 83) disposed interchangeably between the ejection assembly (5) and the movable mould half (4) so as to allow the arrangement of the ejectors

Abstract: A valve to be installed on containers for fluid materials is formed by two coaxial chambers (3) and (4) one of which is internal (3), contains the fluid material and is equipped with a movable piston (10) and a discharging valve (7) including at least one "bypass" hole (8) which connects the two coaxial chambers (3) and (4) in the area between the maximum level of the fluid (18) and the discharging valve (7). An elastic sheath or rubber ring (5) is provided to close and wrap tightly the hole (or holes) (8).

Abstract: As dispenser for fluid products such as perfumes, soaps, deodorizers, insecticides, varnishes, enamels, etc., comprises a chamber (2), containing a fluid to be dispensed and provided with a dispensing valve (10); a seal sliding piston (4) in the chamber (2), and a propellant medium (17) acting on the piston (4) and positioned in a conduit (3) or a chamber coaxial with the chamber (2). The propellant medium may be a spiral spring or compressed air, the pre-charging of which is proportional to the quantity of fluid to be dispensed. When the propellant medium is compressed air, it is contained in a coaxial chamber, annular and external to that of fluid to be dispensed; the external chamber is connected to the bottom of piston (4) by means of radial holes made on the surface of the inner chamber.
