Patent number: 8505785Abstract: A cartridge piston for pressing out a compound from a cartridge body is provided with a forwardly directed, elastic sealing lip which is arranged to bear against the cartridge wall. To allow for escape of air while the piston is being introduced, air passages are provided on the sealing lip. In a wall portion of the side wall, the piston has a non-circular shape so that, in certain regions, the abutment of the piston on the cartridge wall is less close than in other regions. In this manner, the outflow of air to the outside is facilitated. Further, the piston is arranged in its inserted state in a sealing abutment on the cartridge wall, thus precluding ingress of air into the cartridge.Type: GrantFiled: November 30, 2010Date of Patent: August 13, 2013Assignee: Fischbach KG Kunststoff TechnikInventor: Achim Helmenstein

Patent number: 8397959Abstract: A packaging container formed by a container body has a connector with a thread. The connector has a predetermined breaking point where a tear-off part may be torn off. The tear-off part has a handle and may be torn off without a tool. The container body is fitted with an application nozzle which, when not in use, is positioned on the handle.Type: GrantFiled: November 5, 2008Date of Patent: March 19, 2013Assignee: Fischbach KG Kunststoff-TechnikInventor: Achim Helmenstein

Patent number: 8342371Abstract: The caulking gun comprises a cartridge holder (12) for accommodating a cartridge (25). For pressing out the substance contained in the cartridge (25), use is made of a piston (30) which is advanced by a pressure disk (16). The pressure disk (16) can be radially expanded under the influence of the advancement force and thus will press by a spreading edge (49) against the side wall (31) of the piston (30). In this manner, the piston in the region of its side wall (31) is tightly pressed against the cartridge wall. Leakage of substance past the piston (30) is prevented.Type: GrantFiled: December 15, 2009Date of Patent: January 1, 2013Assignee: Fischbach KG Kunststoff TechnikInventor: Achim Helmenstein

Publication number: 20100018977Abstract: A packaging container made of plastic has a fixed wall part (W1), produced by injection molding, and a detachable wall part (W2), which are connected by a predetermined breaking zone (20). The predetermined breaking zone (20) is covered by a barrier layer (24) which provides enhanced barrier action against gases, water vapor or solvent. The barrier layer (24) reduces the permeability of the predetermined breaking zone (20).Type: ApplicationFiled: September 10, 2007Publication date: January 28, 2010Applicant: Fischbach KG Kunststoff-TechnikInventor: Achim Helmenstein

Publication number: 20090194567Abstract: A press-out device for plastic substances comprises a cartridge (10) including a cylindrical container (11) in which a piston (35) can be displaced for pressing a substance, e.g. a sealing substance or adhesive substance, out of a discharge connector (14). The cartridge (10) is provided with an application nozzle (25) for use in extension of the discharge connector (14). The application nozzle (25) belongs to a reclosable closure assembly. The application nozzle (25) further comprises a hood (27) being movable relative to a nozzle body (26) and having a closure orifice. The closure orifice is followed by a discharge channel (51) delimited by straight side walls. The invention makes it possible to open the cartridge (10) without the need for a tool and to adjust and close the application nozzle (25) without the need for a tool.Type: ApplicationFiled: January 27, 2009Publication date: August 6, 2009Applicant: Fischbach KG Kunststoff-TechnikInventor: Achim Helmenstein

Publication number: 20070190275Abstract: Disclosed is a method for producing a tube comprising a compressible peripheral wall in an injection molding process by using an injection mold that is provided with a core and a female die. The opening end of the tube is produced in a neck mold which retains the unfinished tube also during opening of the mold. Special measures prevent the soft plastic of the unfinished tube from sticking to the mold.Type: ApplicationFiled: July 3, 2004Publication date: August 16, 2007Inventor: Achim Helmenstein

Patent number: 6634524Abstract: The two-component cartridge comprises an outer container (10) and an inner container (20) coaxially arranged therein. The inner container (20) comprises a bellows-type section (21) adapted to be folded like an accordion. The rear end of the bellows-type section (21) is inserted into a piston (32). In the folded condition, the bellows-type section is accommodated in an annular space (41) of the piston (32). The piston (32) comprises an annular piston breast (34) and a central piston breast (37) arranged at the same level. The invention allows easy filling of the two-component cartridge from the rear side and almost complete evacuation. The two-component cartridge can be evacuated by means of the same tool as is used for a common cartridge containing only a single material.Type: GrantFiled: March 6, 2002Date of Patent: October 21, 2003Assignee: Fischbach KG Kunststoff-TechnikInventor: Achim Helmenstein
