Patent number: 6193116Abstract: A sifter cap for continuous thread containers of the type adapted to dispense a granular product. There is provided a screw cap adapted for securement to the container, and a sifter member disposed atop the screw cap and adapted for rotation with respect thereto. The screw cap has an annular, upwardly-facing bearing shoulder, and the sifter member has at least three downwardly-faced bearing nibs which slidably engage the bearing shoulder of the screw cap at relatively small areas of contact. The arrangement is such that the the sliding engagement between the screw cap and sifter member is characterized by reduced friction. In addition, in the event that granular product from the container strays onto the bearing shoulder of the screw cap, little resistance against rotation is encountered. As a consequence, there is thus enabled relatively smooth turning of the sifter member on the screw cap.Type: GrantFiled: February 8, 1999Date of Patent: February 27, 2001Assignee: Brent River Packaging CorporationInventors: Robert J.

Patent number: 6186689Abstract: A cosmetic container comprises an insert which is preassembled to a brush by means of an undercut ring located beneath a brush flange and cooperating with an undercut recess in the throat of the insert. The insert walls are held by friction in the container and anchored externally to the container by a ring which extends peripherally from the threaded container wall. An undercut in the insert external flange engages the ring to complete the anchor. The insert is molded from polymer that repels the cosmetic product owing to molecular polarity. The insert functions as a sealing mechanism and a means to keep product from reaching the top of the container or on the container threads. The insert walls may also be shaped as a liquid inhibitor to retard flow from the container if the bottle is tipped over inadvertently.Type: GrantFiled: August 13, 1998Date of Patent: February 13, 2001Inventors: Robert J.
