Patent number: 7556178Abstract: Liquid dispensers are provided including a vacuum relief mechanism with a vacuum relief device and a one-way valve in series with the vacuum relief device to prevent flow into and out of the reservoir when a vacuum exists in the reservoir. The vacuum relief device comprises an enclosed chamber having an air inlet open to the atmosphere and a liquid inlet in communication with liquid in the reservoir and in which the liquid inlet opens to the chamber at a height below a height at which the air inlet opens to the chamber. The one-way valve is capable of failure, in which case the vacuum relief device alone provides for pressure relief. The vacuum relief valve permits relief of vacuum from the reservoir without moving parts or valves.Type: GrantFiled: March 22, 2005Date of Patent: July 7, 2009Assignee: Hygiene-Technik Inc.Inventor: Heiner Ophardt

-
Patent number: 7267251Abstract: A piston pump dispenser having a reciprocating piston pump arrangement which, in a dispensing stroke, dispenses fluid from an outlet and, in a charging stroke, to draw fluid from a reservoir also draws back fluid from the outlet through which fluid is dispensed in the dispensing stroke.Type: GrantFiled: September 13, 2004Date of Patent: September 11, 2007Assignee: Hygiene-Technik Inc.Inventor: Heiner Ophardt
-
Patent number: 7234612Abstract: A delay mechanism including one or more suction cups which during a normal cycle of dispensing from a liquid dispenser come to engage on a surface and thereby delay the return of an actuating member in the dispenser to a position for further dispensing until such time as the suction cup disengages from the surface.Type: GrantFiled: May 11, 2005Date of Patent: June 26, 2007Assignee: Hygiene-Technik Inc.Inventor: Heiner Ophardt

Patent number: 7232045Abstract: An object of the invention is to provide a dispenser which permits its cover to be either locked when closed or unlocked a dispensing device including a lock mechanism for locking a cover to a housing and providing therewith a blocking member which is either coupled to the housing in an inoperative position or can be coupled to the housing in a position which prevents locking of the lock mechanism. The blocking member may preferably be integrally formed from plastic as the same material as another component of the dispenser, preferably from injection molded integrally with a back plate for the housing, at a location which is not visible when the dispenser is used and with the blocking member being removably connected to the housing back plate by a frangible connection which may readily be broken to separate the blocking member from the housing back plate such that the blocking member may be suitably positioned and coupled to the dispenser in a position which prevents locking of the lock mechanism.Type: GrantFiled: March 22, 2005Date of Patent: June 19, 2007Assignee: Hygiene-Technik Inc.Inventors: Heiner Ophardt, Srdjana Jankovic

Patent number: 7225948Abstract: A replaceable fluid container carrying a spray pump with a nozzle which directs spray directionally in which an arrangement is provided for orientating the nozzle into a desired orientation on insertion of the container into a dispenser.Type: GrantFiled: March 29, 2004Date of Patent: June 5, 2007Assignee: Hygiene-Technik Inc.Inventors: Heiner Ophardt, Srdjana Jankovic
-
Patent number: 7178692Abstract: A method of and apparatus for dispensing paste from a collapsible container elongate about an axis from a first closed end to a second open end, the method comprising rotating one of the first end and second end relative to the other to twist the container about the axis, thereby collapsing the container, compressing paste contained therein and extruding the paste from the second open end.Type: GrantFiled: March 24, 2004Date of Patent: February 20, 2007Assignee: Hygiene-Technik Inc.Inventor: Heiner Ophardt

Patent number: 6957751Abstract: Liquid soap dispensers including a vacuum relief valve which comprises an enclosed chamber having an air inlet open to the atmosphere and a liquid inlet in communication with liquid in the reservoir and in which the liquid inlet opens to the chamber at a height below a height at which the air inlet opens to the chamber. The vacuum relief value permits relief of vacuum from the reservoir without moving parts or values.Type: GrantFiled: April 26, 2002Date of Patent: October 25, 2005Assignee: Hygiene-Technik Inc.Inventor: Heiner Ophardt

Patent number: 6601736Abstract: A pump assembly provides for direct replacement of volumes of liquid from a reservoir with equal volumes of air preferably at substantially atmospheric pressure, the same pressure or with pressure equalization to be at least equal to atmospheric pressure. A slide arrangement preferably positively displaces liquid from the reservoir and air into the reservoir. The pump draws air from the atmosphere into a chamber from which the air either is available for passage to replace liquid from the reservoir or is pressurized to assist dispensing liquid, preferably, admixing with the liquid to provide foaming. Gravity separation of air and liquid to be dispensed is used to replace liquid with air in the reservoir and to selectively place air and liquid into communication with passageways for ejection.Type: GrantFiled: April 9, 2002Date of Patent: August 5, 2003Assignee: Hygiene-Technik Inc.Inventors: Heiner Ophardt, Ali Mirbach

Patent number: 6343724Abstract: A valve assembly for a fluid dispensing unit, particularly for a soap dispenser, comprising a resilient valve member secured within a chamber. Valve member comprises a sealing member, a support member and a securement member. The support member carries sealing member at one end and securement member at the other end. The valve member when secured within the chamber is under compression with the sealing member biased by the support member engaging and sealing the inlet port of the chamber to fluid flow therethrough other than fluid flow under a pressure differential across sealing member sufficient to resiliently deflect the sealing engagement. The valve member is formed entirely from recyclable plastic as an integral unit by injection molding.Type: GrantFiled: September 14, 2000Date of Patent: February 5, 2002Assignee: Hygiene Technik Inc.Inventors: Herman Ophardt, Heiner Ophardt, Ali Mirbach
