Patent number: 7654415Abstract: The invention relates to a combination of a first container and a second container to form a dispensing unit. The first and second containers each have a reservoir for a liquid substance and pump which is secured to the reservoir, can be actuated by hand and has a dispensing opening and a pump-actuating button for dispensing substance from the reservoir. The combination also comprises coupling means for coupling together the first and second containers in a position next to one another. The invention is characterized in that the coupling means comprise: one or more first coupling members, which are each arranged on the first container, and one or more second coupling means, which are each arranged on the second container and which can each be directly coupled to an associated first coupling member on the first container.Type: GrantFiled: March 11, 2003Date of Patent: February 2, 2010Assignee: Airspray International B.V.Inventor: Edgar Ivo Maria van der Heijden

Patent number: 7588170Abstract: The invention relates to a dispensing unit for dispensing two fluid substances. The dispensing unit comprises a pump assembly (2) having a first (4) and a second pump (5) which can be actuated by common, manually operable operating means (6) in order to simultaneously dispense the two fluid substances. The dispensing unit also comprises a reservoir assembly (3), the reservoir assembly comprising two reservoirs which are each provided at an outlet side with an outlet and are each delimited by a movable piston (13, 16) on the other side from the outlet, which pistons, during the dispensing of the fluid substances, move toward the respective outlets. According to a first aspect of the invention, the reservoir assembly (3) and the pump assembly (2) are separate assemblies which can be coupled to one another, in such a manner that in the uncoupled state each reservoir can be filled through the outlet of the reservoir, after which the pump assembly and the reservoir assembly are coupled to one another.Type: GrantFiled: June 18, 2003Date of Patent: September 15, 2009Assignee: Airspray International B.V.Inventor: Edgar Ivo Maria van der Heijden

Patent number: 5337929Abstract: A mixing chamber for mixing a gaseous component with a liquid component is disclosed. The mixing chamber is characterized by separate inlet connections for the respective components and an outlet for the mixture to a space at a lower pressure. The propellant inlet comprises a plurality of narrow channels positioned to create a turbulent flow in the mixing chamber to facilitate mixing of the components. Also disclosed is a method for forming narrow channels in a body or object by forming grooves in one of two interconnecting surfaces of the parts to thereby define the narrow channels when the parts are put together to form the body or object.Type: GrantFiled: February 7, 1992Date of Patent: August 16, 1994Assignee: Airspray International B.V.Inventor: Edgar I. M. van der Heijden
