Patent number: 7819341Abstract: The invention relates to a gravity flow reservoir for a paint spraying gun having a container and a cover, which can be placed thereon and which has a connecting part in order to place the gravity flow reservoir onto the paint spraying gun or onto an adapter. Prior art reservoirs require a separate pointed tool, which serves to make a vent hole, is often unavailable and can lead to operating errors. The aim of the invention is to provide a paint reservoir system that enables a simple, rapid and uncomplicated insertion of a vent hole into the container wall of the gravity flow reservoir while preventing shavings or plastic parts from entering the gravity flow reservoir. To this end, a delimited area is provided in the wall of the container and can be penetrated by the pointed tool in order to make a vent hole.Type: GrantFiled: January 18, 2005Date of Patent: October 26, 2010Assignee: Sata GmbH & Co. KGInventors: Ewald Schmon, Peter Dettlaff

Patent number: 7815130Abstract: A paint reservoir has a fluid outlet 115 connectable to a spray gun 101 and a fluid inlet 131 provided with a removable screw cap 132 whereby the fluid inlet 131 is directly accessible for introducing paint to the reservoir while attached to the spray gun 101. The fluid outlet 115 and fluid inlet 131 may both be provided in an end wall of the reservoir with outlet 115 located on the longitudinal axis of the reservoir or offset to allow the size of the fluid inlet 131 to be increased for easier filling of the reservoir. The outlet 115 can be aligned with the longitudinal axis of the reservoir or it can be inclined relative to the longitudinal axis to provide greater clearance for access to the fluid inlet 131 when the reservoir is attached to the spray gun 101. In an alternative arrangement, the fluid outlet is provided in an end wall of the reservoir and the fluid inlet is provided in a sidewall of the reservoir.Type: GrantFiled: October 13, 2006Date of Patent: October 19, 2010Assignee: 3M Innovative Properties CompanyInventors: Stephen C. P. Joseph, Michael J. R. Adams, Antonio Bacciocchi, Malcolm F. Douglas, Daniel E. Siltberg

Patent number: 7798427Abstract: A spray gun (1) has a fluid reservoir (11) with a removable liner (13) received in a container (12) having a detachable lid (15). The liner (13), which may be thermo/vacuum-formed from a planar material, has a shape that corresponds to and is a close fit within the interior of the container (12) and collapses as fluid is withdrawn from within the liner (13) during operation of the spray gun (1). The lid (15) has an outlet (16) connected to an inlet on the spray gun (1) for transfer of liquid from the reservoir (11) to the spray gun (1) and the container (12) has a vent (12A) in the base end for admitting air between the container (12) and the liner (13) as liquid is withdrawn from within the liner (13).Type: GrantFiled: March 23, 2006Date of Patent: September 21, 2010Assignee: 3M Innovative Properties CompanyInventors: Stephen C. P. Joseph, Malcolm F. Douglas, Alan F. Butler

Patent number: 7798425Abstract: A spray gun (1) has a fluid reservoir (11) which contains a removable liner (13). The liner (13), which may be thermo/vacuum-formed from a plastic material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir (11) has a removable lid (15) and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid (15) also functions to secure the liner (13) in the reservoir and, at the end of a spraying operation, the lid (15) and the liner (13) are removed together from the reservoir (11) and discarded, thereby simplifying the cleaning of the spray gun.Type: GrantFiled: June 30, 2004Date of Patent: September 21, 2010Assignee: 3M Innovative Properties CompanyInventors: Stephen C.

Patent number: 7789324Abstract: A connector system for releasably securing a reservoir to a spray gun includes hook members on a lid of the reservoir that engage a flange of an inlet adaptor on the spray gun with a push/twist action to secure the reservoir to the spray gun. A retainer clip mounted on the inlet adaptor is movable between an inoperative position to allow the reservoir to be connected to and disconnected from the spray gun, and an operative position in which the clip blocks release of the reservoir. The clip provides security against accidental release of the reservoir in use of the spray gun.Type: GrantFiled: January 10, 2007Date of Patent: September 7, 2010Assignee: 3M Innovative Properties CompanyInventors: Phillip J.
