Publication number: 20220203392Abstract: In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator.Type: ApplicationFiled: May 7, 2021Publication date: June 30, 2022Inventors: Wilhelmus Johannes Joseph Maas, Dominicus Jan van Wijk, Paulo Nervo, Petrus Lambertus Wilhelmus Hurkmans, Aaron Haleva

Patent number: 11027298Abstract: Dispensing devices can include buffers. This obviates the need for continually pumping the device to dispense spray or foam. A buffer can be spring loaded, spring loaded combination, elastomeric or gas, and can be in line or adjacent to a piston chamber. Such sprayers and foamers can be mounted upside down. With a buffer, a piston chamber can deliver a greater amount of liquid per unit time than can be dispensed through the nozzle(s). The fraction of liquid that cannot be dispensed can be sent to the buffer for dispensing after the piston downstroke has completed. Volume of the piston chamber and buffer, pressure response of the buffer, throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.Type: GrantFiled: November 6, 2013Date of Patent: June 8, 2021Assignee: Dispensing Technologies B.V.Inventors: Wilhelmus Johannes Joseph Maas, Dominicus Jan van Wijk, Paulo Nervo, Petrus Lambertus Wilhelmus Hurkmans, Aaron Haleva

Patent number: 9205952Abstract: A composite container, comprising a form-retaining outer container comprising a neck, and a flexible inner container, the inner container comprising a dispensing opening mounted in the neck of the outer container is presented. The inner container is connected over a part of its surface area near the dispensing opening to a corresponding surface area of the inside of the outer container near the neck, via adhesive or weld connection, such that there remains a portion of the inner container not connected to the sidewall of the outer container. In response to an overpressure developed by a displacing medium introduced between the inner container and the outer container, a portion of the inner container that is not connected to the outer container moves at least one of: (i) towards the dispensing opening and (ii) within, the portion of the inner container that is connected to the outer container.Type: GrantFiled: May 29, 2014Date of Patent: December 8, 2015Assignee: Dispensing Technologies B.V.Inventors: Wilhelmus Johannes Joseph Maas, Dominicus Jan Van Wijk, Josephus Cornelius Snijders

Publication number: 20150108077Abstract: A composite container, comprising a form-retaining outer container and a flexible inner container is presented. The inner container comprises a dispensing opening and can be mounted in a neck of the outer container, and the inner container is further connected to the outer container by an adhesive or weld connection over a portion of its periphery. The adhesive or weld connection can take the form of a ring adhesion or weld extending transversely to a central longitudinal axis of the container, or can cover the entire surface area of a defined portion of the respective inner container and outer container walls, such as, for example, the upper one-half of the container. The adhesion or weld can be substantially permanent, or alternatively, the adhesive or weld connection can be adapted to detach in controlled manner under the influence of pressures occurring in the container.Type: ApplicationFiled: August 5, 2014Publication date: April 23, 2015Inventors: Wilhelmus Johannes Joseph MAAS, Dominicus Jan Van Wijk, Josephus Cornelius Snijders
