Patent number: 4736874Abstract: A pouring apparatus for use on a liquid-carrying container such as a paint can for preventing inadvertent spillage onto the can, the apparatus having a wedge-shaped annulus for insertion into the open mouth of the can and for frictional engagement with the inner rim of the can without being supported on the top or side wall of the can. A spout member provides a pouring surface which may be either integral to or separate from but supported by the annulus. Where the pouring surface is separate, it may be made of a disposable material such as paper. Such disposable material pouring surface or spout member is preferably secured between the wedge-shaped annulus and the inner rim of the can. This is facilitated by shaping the secured portion of the spout member to conform to the wedge shape of the annulus.Type: GrantFiled: November 24, 1986Date of Patent: April 12, 1988Inventor: Will G.

Patent number: 4612964Abstract: A valve bag filling apparatus that combines an auger-type feed and an air pressure-type feed in a unitary filling system for filling valve bags with flowable particulate material at higher speed and with greater accuracy. A concentric tube configuration is used to deliver such material at high speed into the bag during a major portion of the filling cycle with both feed systems acting simultaneously. A novel cutoff tube closes an annular air feed passage during the final portion of the filling cycle when the auger feed portion of the system completes the bag filling operation at a highly accurate and readily controlled low feed rate. Air purge jets clear the air passage of remaining material during the final portion of the filling cycle. A unique fluidizing section of the apparatus aerates the product and feeds it into both the auger and air passage during high speed filling.Type: GrantFiled: April 1, 1985Date of Patent: September 23, 1986Assignee: Westmont, Inc.Inventor: Will G.
