Patent number: 4634019Abstract: A metal container cover is swingably connected to a metal container body by a hinge which consists of a single-piece extrusion of resiliently yieldable plastic. The hinge is generally S-shaped in transverse cross-section and includes upper and lower hook sections adapted to be snap-assembled with the body and the cover, respectively. A slot in the cover accommodates the lower hook section to enable the cover to swing to an open position.Type: GrantFiled: March 14, 1986Date of Patent: January 6, 1987Assignee: J. L. Clark Manufacturing Co.Inventor: Douglas E. Pherigo

Patent number: 4621744Abstract: Three hinged flaps of a plastic container closure are molded while in open positions and, during molding of the flaps, an elongated tear-away strip is formed along the front edges of the flaps and is integrally connected to the flaps by tearable webs. After the newly molded flaps have first been closed, the strip is anchored releasably to the top panel of the closure and prevents the flaps from opening during shipment of the container, the strip also serving as a visual indicator that the seal of the closure is intact. The closure is opened by lifting and pulling on the strip to tear the latter completely away from the top panel and the flaps and to free the flaps for swinging to open positions. The absence of the strip or the presence of a partially torn strip indicates that tampering has occurred and that the seal may not be intact.Type: GrantFiled: January 6, 1986Date of Patent: November 11, 1986Assignee: J. L. Clark Manufacturing Co.Inventor: John A. Foster

Patent number: 4471881Abstract: Lugs secure the mounting leaf of a plastic hinge within an inwardly offset recess formed in the upper lip portion of a metal container body. Flexible hinge straps are molded integrally with the mounting leaf and support a cover on the body for swinging between open and closed positions. In one embodiment, the cover is made of plastic and is molded integrally with the hinge straps. In a second embodiment, the cover is made of metal and is secured to a second mounting leaf which is molded integrally with the hinge straps.Type: GrantFiled: June 28, 1983Date of Patent: September 18, 1984Assignee: J. L. Clark Manufacturing Co.Inventor: John A. Foster

Patent number: 4361250Abstract: The hinged flap of a plastic container closure is molded while in an open position and, during molding of the flap, hinged strips with depending pins are formed along the sides of the flap and are integrally connected with the flap by tearable webs. After the flap has first been closed, the pins are anchored to the top of the closure and prevent the flap from opening during shipment of the container. Initial opening of the flap is effected by swinging the flap upwardly with a substantial force to tear the webs and separate the webs from the strips and the anchor pins, the torn webs providing a visual indication that the flap has been opened.Type: GrantFiled: June 26, 1981Date of Patent: November 30, 1982Assignee: J. L. Clark Manufacturing Co.Inventor: John A. Foster

Patent number: 4098421Abstract: A container for snuff includes a cup-shaped body and a cup-shaped cover both molded of plastic. When the cover is telescoped onto the body, an inwardly projecting rib on the cover snaps past an outwardly projecting rib on the body and then presses against the body to hold the cover releasably on the body while establishing a seal between the cover and the body.Type: GrantFiled: June 24, 1977Date of Patent: July 4, 1978Assignee: J. L. Clark Manufacturing Co.Inventor: John A. Foster

Patent number: 4059201Abstract: The dispensing opening of a container closure is originally sealed with foil which may be torn out of the opening by a hinged door located removably in the opening.Type: GrantFiled: March 14, 1977Date of Patent: November 22, 1977Assignee: J. L. Clark Manufacturing Co.Inventor: John A. Foster

Patent number: RE30447Abstract: A laminated tubular connector for splicing or terminating electric conductors, comprising an outer layer of a heat shrinkable dielectric material, e.g., polyethylene terephthalate, and an inner layer of relatively soft, self-adhesive, low temperature flowable thermoplastic material, preferably a polyvinyl acetate composition. When heat is applied to the connector, the outer layer shrinks and the inner layer functions as a sealant and a cushioning agent. In some applications, the adhesiveness of the inner layer may be used to hold the connector in place during subsequent operations by pinching the connector so that the depressed portions of the tube adhere to each other prior to heating the connector to shrink the outer layer.Type: GrantFiled: February 23, 1979Date of Patent: December 16, 1980Assignee: J. L. Clark Manufacturing Co.Inventors: Patrick V. Loyd, Samuel M. Mills
