Patent number: 10336516Abstract: Childproof safety cap has two opposite bead-like threads on its inner wall. Each thread has a widened end region, a stop surface thus being formed. The associated bottle has two opposite groove-like threads on a connecting piece of the bottle, each of which threads has a widened region in the end region, an undercut thus being formed in the groove by the widened region. When the safety cap is screwed on, the stop surfaces on the two bead-like threads hook in behind the undercuts on the groove-like threads. The stop surfaces can be released from each other only if the safety cap is pressed down toward the bottle onto the connecting-piece neck. Connecting-piece neck forms a slipping surface that conically expands downwards. The safety cap can then be unscrewed while simultaneously being rotated.Type: GrantFiled: December 17, 2015Date of Patent: July 2, 2019Assignee: AERO PUMP GMBHInventors: Ralf Heim, Andreas Mersmann

Patent number: 6851583Abstract: A double-acting pump for ejecting a product from a container includes a piston which is axially slideable in a housing and is sealed by the housing. A hollow piston rod extends the axial bore of the piston and is slideable in a closing cap and has an actuating head, wherein, when the actuating head is actuated, the piston builds up a pressure in a pressure chamber against a restoring force of a spring. An outlet duct extends through the actuating head to an outlet opening. When subjected to the restoring force of the spring, the piston releases a passage between the pressure chamber and openings of a second housing portion. A medium which kills germs and bacteria is arranged in an expansion chamber. The dispensing stroke volume of the piston corresponds to the volume of a drop of the liquid.Type: GrantFiled: July 11, 2003Date of Patent: February 8, 2005Assignee: AERO Pump GmbHInventors: Ettore Masuzzo, Stefan Christ

Patent number: 6824021Abstract: An actuating head (12) of a double-acting pump (1) for ejecting a product (38) from a container (2) includes an outlet duct (13a-13d) leading to an ejection opening (16), wherein a closing piece (18) biased by a spring (17) is arranged in the outlet duct. The closing piece (18) directly seals the ejection opening (16) under the force of the spring (17) and the closing piece (18) releases as a result of the pressure exerted when actuating the double-acting pump (1) the flow of the product (38) through the outlet duct (13a-13d) and through the ejection opening (16) against the force of the spring (17).Type: GrantFiled: January 10, 2003Date of Patent: November 30, 2004Assignee: Aero Pump GmbH, ZerstäuberpumpenInventors: Ettore Masuzzo, Stefan Christ

Patent number: 6779690Abstract: A double-acting pump for ejecting a product from a container, with a housing in which a piston with an axial bore is axially slideable and sealed by a first housing portion, with a hollow piston rod which extends the axial bore of the piston and is slideable in an opening of a closing cap of the housing and container. When an actuating head is actuated, it presses the piston against the force of a restoring spring toward a connecting pipe portion for an immersion pipe provided in the housing, so that a pressure is built up in a pressure chamber of the housing which presses a first valve closing piece in the connecting pipe piece against a first valve seat.Type: GrantFiled: July 11, 2003Date of Patent: August 24, 2004Assignee: AERO Pump GmbHInventors: Ettore Masuzzo, Stefan Christ

Patent number: 6776312Abstract: A actuating head of a double-acting or lift and force pump for ejecting a product from a container includes an outlet duct leading to an ejection opening, wherein a valve closing piece is arranged in the outlet duct. Together with the outlet duct, the valve closing piece forms a check valve which, when the actuating head is actuated, is opened by the pressure of the product and allows the product to flow into a space defined by the inner side of the outlet duct and the circumference of the valve closing piece. This space is connected through at least one transverse groove to the ejection opening. The valve closing piece is elastically deformed by the product pressure when the actuating head is actuated and opens the check valve. The valve closing piece borders against the transverse groove and rests with its rear side against a radially inwardly protruding shoulder of the outlet duct.Type: GrantFiled: January 10, 2003Date of Patent: August 17, 2004Assignee: Aero Pump GmbH, ZerstäuberpumpenInventors: Ettore Masuzzo, Stefan Christ
