Abstract

A manually operable spreading apparatus for uniformly spreading flowable material, such as a sealant or adhesive, on a surface comprises a handle with a transversely extending spreader blade at one end and a reservoir chamber for the flowable material mounted on the handle. Valve means at the resevoir lower end are operable to discharge material from the reservoir for engagement by the spreader blade. Preferably the reservoir chamber is provided with a lining of flexible plastics material that also comprises a container for the flowable material. The lining preferably is of length greater than the reservoir chamber so that its lower end extends into the close neighbourhood of the spreader blade. The lining may be provided by a sealed bag of the material, the lower end of which is opened after installation, or by an open-ended tube, the lower ends of the bag or tube being closable by the valve means. The reservoir body preferably is of circular cross section and the valve body preferably is circular in end elevation and Z shape in side elevation, the bottom bar of the Z comprises a blade valve closure member; a spring is interposed between the cross bar of the Z and the handle to close the valve. The spreader blade preferably is provided with a pair of spring urged side retainer blades pivoted at respective ends to form therewith a rectangular structure confining the material to the area of the surface over which the spreader blade moves.
