Dispensing apparatuses (10) for administering particulate materials are presented. In an embodiment, the present disclosure provides a dispensing apparatus (10) including an overcap (30) having a lid (32) having an attachment mechanism (50) connected to a portion of a surface of the lid and rim (34) hingedly attached to the lid and comprising a gripper (60) constructed and arranged to hold a scoop (20). The scoop can be releasably attached to the lid and the rim of the overcap in a variety of ways.

Maintenance-friendly, compact valve having a simple design for essentially gastight closing of a flow path between two ports arranged at an angle. A valve part which is arranged in a valve housing so as to be displaceable along an axis and whose closing surface can be brought into contact with a valve seat of the first port for closing the flow path and can be brought out of contact for opening the flow path is in the form of a cylindrical piston having an end face forming the closing surface and a piston outer surface. The valve housing has a cylindrical passage which extends opposite the valve seat along the axis and through which the piston is passed and can be displaced and inside which a sealing or guide element is arranged. The piston and the passage are dimensioned so that the piston outer surface is closely enclosed along the adjustment distance by the sealing or guide element of the passage. It is thus possible for essentially only a single adjustable component of the valve, namely the easily cleanable piston consisting in particular of a single material, to be guided in the flow space so that the maintenance of the valve is substantially simplified and few different materials bound the flow space. In a further development, the drive mechanism of the piston is formed at least partly by an outer piston space between a piston step and the passage, so that the piston forms a component of the drive mechanism, permitting a compact design of the valve.

In a spray gun ( 1 ) for spraying paint with a gun housing ( 2 ) provided with a handle ( 3 ) with a union nut ( 10 ) screwed onto it that holds an air cap ( 11 ) provided with offset outlet openings ( 14, 15 ) for compressed air, the union nut ( 10 ) is positively connected to the air cap ( 11 ) in a circumferential direction. This embodiment makes it possible for the spray jet to be set in a brief time and without difficulties without having to put up with getting dirty. It is merely necessary to turn the union nut ( 10 ) accordingly in order to control the air supply to the outlet openings( 14, 15 ) of the air cap ( 11 ) and therefore to influence the formation of the spray jet.

The invention provides a wall hanging fixing device which is conveniently installed. The wall hanging fixing device comprises a decoration cover, wherein the inner side of the decoration cover is provided with a hanging part which is fixed on a support on the inner side of the decoration cover via screws, and the hanging part is provided with a hanging connection groove which is fit with a supporting part. The fixing device is also provided with a movable part which can move towards and away from the hanging connection groove. The invention provides the rapid installation structure of the wall hanging articles in bathrooms, after expansion bolts are fixed, the fixing device is placed on the expansion bolts, the hanging part is hung on the expansion bolts, then the fixing device can be fixed by directly screwing the bolts, which is quite convenient without any disassembly in background technology, the hanging part in the bathrooms and the surface of the decoration cover can not be polluted or scratched, high-end bathroom products are protected, and the hanging part in bathrooms can be tightly fixed due to the global stress of the fixing structure, which effectively prevents looseness.

Swinging open the upstream-side cover part ( 31 ) and downstream-side cover part ( 32 ) of the check scanning apparatus ( 1 ) on a common support pivot ( 33 ) opens a U-shaped check transportation path ( 5 ). The check transportation path ( 5 ) can be opened with a simple single-action operation to remove checks ( 4 ) jammed in the check transportation path ( 5 ) and for maintenance of the magnetic head ( 84 ) and contact image sensors ( 82 and 83 ). When the task is completed, the open check transportation path ( 5 ) can also be returned to the original closed position by a simple single-action operation. If only those parts that require maintenance are exposed when the check transportation path is open, tasks that require opening the transportation path can be done without damaging other parts and without soiling the operator's fingers.
