Abstract: A dosing pump for liquids has a cylindrical chamber for receiving the liquid to be dispensed, a piston located in the chamber slidable between a rest and a dispensing position. A valve near the inlet of the cylindrical chamber closes the chamber to block incoming liquid flow when the pump is moved to the dispensing position and opens for drawing liquid into the chamber as the piston returns to the rest position. A valve near the outlet of the pump allows liquid flow to the outlet during the dispensing stroke and blocks the outlet during the return stroke. The pump is formed of one or more compatible plastic materials which are recyclable and compatible so that the entire pump may be recycled as a unit without disassembly and sorting of parts.

Abstract: A cap with a safety opening system which includes an inside element (10) being screwed on the bottle neck, an outside cylindrical element (30) being coaxial to the inside element and a push-button (20) placed between the inside element and the outside one.When the push-button (20) is pressed toward the bottle, it interacts with the cogged rim (16) being present on the upper part of the inside element and it works as a transmission means between the outside element (30) being made to rotate in the cap untightening direction, and the inside element (10) being screwed on the neck of the bottle. When the pressure exerted by the push-button (20) stops, it is only possible to tighten the cap by rotating the outside element (30), said element being provided with a cogged rim (14) on its internal lateral surface (31) which engages with a corresponding cogged rim (13) being present on the external cylindrical surface of the inside element (10).
