Publication number: 20170158413Abstract: The invention relates to a cartridge for at least two flowable components. The invention starts from a cartridge having at least two storage containers into which pistons can be inserted for dispensing components. So that the pistons cannot slip out of the storage containers again after the insertion, peripheral beads are provided at inner walls of the storage containers. To make possible cartridges which can be manufactured inexpensively and which can nevertheless be reliably sealed, it is proposed in accordance with the invention that the first inner wall has a first connection section and the second inner wall has a second connection section in which they do not have a bead. A connection web which connects the two storage containers is in this respect arranged between the first and second connection sections.Type: ApplicationFiled: February 16, 2017Publication date: June 8, 2017Inventors: Ralf SEIFER, Manfred OBRIST

Patent number: 9144821Abstract: A piston includes a piston body which is surrounded by a media side, by an oppositely disposed drive side and, at the peripheral side, by a piston jacket, wherein the piston jacket forms a connection between the media side and the drive side. The piston jacket is arranged about a piston axis, wherein the piston jacket is connected to the piston body via a web element so that a peripheral groove is formed on the media side between the piston body and the piston jacket. A cover element is arranged at the media side, and has a drive side surface which lies directly on the media side surface of the piston body.Type: GrantFiled: December 8, 2010Date of Patent: September 29, 2015Assignee: SULZER MIXPAC AGInventor: Manfred Obrist

Patent number: 8919616Abstract: The piston includes a piston body having a conveying side, an oppositely disposed drive side and, at the circumferential side, a piston jacket forming a connection between the conveying side and the drive side. The piston jacket has a projection that carries a guide element for the guidance of the piston in a cartridge containing a filling with solid particles and for forming a sealing contact with a wall of the cartridge. The projection also carries a scraper element in front of the guide element for scraping solid particles from the cartridge wall back into the filling during discharge.Type: GrantFiled: November 20, 2009Date of Patent: December 30, 2014Assignee: Sulzer Mixpac AGInventor: Manfred Obrist

Patent number: 8875947Abstract: A dual dispensing apparatus for dispensing two flowable components having a first storage chamber for the first component, and a second storage chamber for the second component. The two storage chambers are arranged next to one another and each have an outlet for the first or the second component respectively at their distal ends. The apparatus also has a first plunger for penetrating into the first storage chamber and a second plunger for penetrating into the second storage chamber. A respective piston for dispensing the respective component is molded to each plunger and is sealingly guided by the respective wall of the storage chamber. Each storage chamber has at least one first guide element at its end remote from the outlet and each plunger has at least one second guide element adjacent to the respective piston. The first and the second guide elements are configured for mutual engagement.Type: GrantFiled: September 30, 2011Date of Patent: November 4, 2014Assignee: Sulzer Mixpac AGInventors: Manfred Obrist, Ralf Seifer
