A flap is integrally connected to the upstanding member of the hinge assembly by a strap. A portion of reduced thickness is formed in the strap to create a hinge at the juncture of the strap and the upstanding member. The portion of the reduced thickness of the strap is formed by an inclined slot cut in the tubular body near the top end wall and extending into the upstanding member.Type: GrantFiled: November 15, 1982Date of Patent: July 3, 1984Assignee: Knight Engineering & Molding Co.Inventor: Alois R.

Patent number: 4444340Abstract: A removeable and replaceable self-sealing valve formed of resiliently flexible plastic which has inner and outer concentric walls spaced to provide an axially inwardly-opening socket for receiving the outer end of a semi-rigid plastic spout carried by a flexible plastic bag. The spout has one or more inner anular sealing ribs formed therein at a location spaced axially-inwardly from its lip and the inner wall normally resiliently engages this seal. A toggle lever is connected to the inner wall to flex it so that a portion thereof is flexed away from the sealing rib to open a dispensing passage to an outlet in the outer wall beyond the spout lip. A removable seal retainer insert holds the inner wall in sealed position until the valve is to be used.Type: GrantFiled: May 27, 1982Date of Patent: April 24, 1984Assignee: Liqui-Box CorporationInventors: Curtis J. Bond, John G. Ulm

Patent number: 4386720Abstract: The invention relates to a tap for connection to a tube extending from a container for liquids. It includes a barrel having a substantially continuous hollow configuration open at one end and having an outlet opening in its sidewall. The open end of the barrel is adapted for fastening the barrel to the container. There is included a seat surrounding the outlet opening and complimentary plug extending into the interior of the barrel and carried by the closed opposite end of the barrel. At least a portion of the barrel is of a flexible thin-walled diaphragm-like configuration and is adapted to be inverted by a snap action from an open position to a closed position with the plug engaging the seat when in the closed position to shut off the flow of liquid through the tap.Type: GrantFiled: January 22, 1982Date of Patent: June 7, 1983Assignee: Illinois Tool Works Inc.Inventor: Robert Speedie

Patent number: 4358032Abstract: A container closure such as a bottle top or the like is provided having a base portion for assembly onto the container forming a top to the container, the base portion having an orifice therethrough set in a generally planer top surface. A top member lies atop the planer surface and has a hinge defining the top member into two portions, one of which has structure for affixing it in face to face relationship with the planer surface on top of the base. The other portion is movable about the hinge from an orifice closing position atop the planer surface to an orifice open position extending at an angle to the planer surface. A flexible tongue extends into the area of the hinge and is capable of undergoing a snap movement from one side to the other of a raised rib in the planer surface to hold the second portion of the top in the orifice open position at an angle to the planer surface. The second portion of the top may be equipped with a stopper insertable into the orifice.Type: GrantFiled: December 24, 1980Date of Patent: November 9, 1982Inventor: Sidney M. Libit

Patent number: 4291818Abstract: A lid made of a synthetic resin and swingable like a cover for a book to open or close the opening of a container. A leg or legs of desired length extending rearwardly from the rear end of a lid plate renders the lid plate capable of maintaining a desired open position, and moving automatically into its open and closed positions. Such capabilities of the lid plate depend on the force created by a flat surface carrying a hinge base to urge the free end of the leg upwardly, the elasticity of a hinge and the hinge base, and the distance defined between the hinge and the free end of the leg which has been moved. The lid is particularly suitable for a compact for a cosmetic, or the like.Type: GrantFiled: April 22, 1980Date of Patent: September 29, 1981Assignee: Yoshino Kogyosho Co., Ltd.Inventors: Takamitsu Nozawa, Takaharu Tazaki

Patent number: 4278179Abstract: A container closure lid and container dispensing top including a container dispensing top and a closure lid pivotally mounted on the container top and movable between an open position and a closed sealing position. The container lid further includes elongated serations disposed in an opposing relationship such that upon closure the serations will mate and form a multiple lock. The container lid is pivotally mounted to the container top through pivot points below the closure surface of the container top and the container top closure surface is generally inclined downwardly toward the pivot points.Type: GrantFiled: December 10, 1979Date of Patent: July 14, 1981Inventor: Richard L. McWilliams

Patent number: 4211348Abstract: A spigot for dispensing the liquid contents of a container having a filling and dispensing spout adjacent the bottom thereof comprising an integral elastomeric member of generally cup shape having a peripheral wall complementary to and adapted to fit within and seal against the inner surface of the spout axially inwardly of the lip of the spout, a transverse wall at the inner end of said peripheral wall for closing off the spigot and the spout, and a manipulatable lever on said transverse wall for flexing said transverse wall and a portion of said peripheral wall to move said portion of said peripheral wall radially inwardly away from the spout to permit the dispensing of the contents of the container, said walls automatically and resiliently snapping back into their spout sealing positions upon release of said manipulatable means.Type: GrantFiled: January 30, 1978Date of Patent: July 8, 1980Inventor: William R. Scholle

Patent number: 4158902Abstract: An improved integral snap action hinge comprises first and second main parts joined together by a plurality of hinge straps each of which includes a flexible intermediate portion which portions are aligned to define a hinge line which accommodates opening and closing of the hinge. Improved hinge also includes first and second hinge members, at least one of which is comprised of a flexible, resilient material. The first hinge member extends upward from the first main part between two of the hinge straps. The second hinge member extends upward from the second main part between the same two hinge straps, and confronts the first hinge member when the hinge is in the open position.Type: GrantFiled: September 30, 1977Date of Patent: June 26, 1979Inventors: Milton P. Chernack, Armand A. Fiorenza

Patent number: 4124151Abstract: A "toggle" type dispensing closure can be constructed so as to utilize a first closure part such as a cap or the top of a container upon which there is pivotally mounted a second closure part such as a lid so that the second closure part may be pivoted between a closed position in which an opening through the first part is closed off and an open position in which material may be moved through the opening. With such a closure one end of a spring is pivotally connected to the first closure part and the other end of the spring is pivotally connected to the other closure part. The spring is connected to these two parts at spaced locations such that the distance between the ends of the spring is decreased as the second closure part is moved between these positions.Type: GrantFiled: November 22, 1976Date of Patent: November 7, 1978Assignee: Polytop CorporationInventor: Robert E. Hazard

Patent number: 4083476Abstract: An improved manually actuated liquid-atomizing pump assembly for non-pressurized pharmaceutical atomizers comprising a pump actuator unit and a pump unit, which causes a spray of substantially the same particle size spectrum to be discharged from the atomizer nozzle with each actuation of the pump; the improvement resides in a resilient mechanical resistance interposed between the manual pump actuator and the pump, where the resilient resistance requires a very definite amount of force to be overcome.Type: GrantFiled: December 2, 1976Date of Patent: April 11, 1978Assignee: Boehringer Ingelheim GmbHInventors: Hans Schwartz, Helmut Franz
