Patent number: 5955713Abstract: A tilt switch array is used to determine the orientation of an object relative to an upwards direction. The array includes at least one pair of electrodes within a housing, diametrically opposed along a measurement axis. A conductor equidistantly surrounds each electrode to form a tilt switch gap therebetween. A moveable conducting element within the housing closes the gap between one electrode and its associated conductor under certain orientation conditions of the measurement axis relative to an upwards direction. A number of pairs of electrodes may be placed within the housing, with associated measurement axes so that the orientation of any one of the measurement axes may be detected.Type: GrantFiled: October 3, 1997Date of Patent: September 21, 1999Assignees: Circle Seal Corporation, Joint Techno Concepts International, Inc.Inventors: John S.

Patent number: 5939620Abstract: A leak detection system determines whether a container has a leak or an aperture by attempting to draw a vacuum in the container and determining whether a vacuum has been created in the container. If a vacuum can be created in a container, this indicates that the container has a leak. Conversely if a vacuum cannot be created in the container, this indicates that the container does not have a leak. The leak detection system preferably includes a conveyor system for moving a container and a sensor for sensing the pressure in the interior of the container through an opening in the top of the container. While the sensor is sensing the pressure in the interior of the container, a vacuum pump pulls air from the region around the exterior of the container. If the container has an aperture, a vacuum will be created in the container and will be noted by the sensor.Type: GrantFiled: April 24, 1998Date of Patent: August 17, 1999Assignee: Crown Cork & Seal Technologies CoporationInventor: Edward J. Strand

Patent number: 5938389Abstract: A method of making a non-cylindrical shaped metal can that is provided with a stylized, irregular shape includes steps of forming a substantially cylindrical sidewall portion (12) that has a plurality of ribs integrated therein. These ribs provide additional strength to the sidewall portion. The cylindrical sidewall portion may then be shaped into a non-cylindrical, stylized shape. The ribs (26) are preferably positioned at portions of the shaped sidewall portion (12) that are anticipated to need increased strength in order to withstand deformation under pressure. The sidewall (12) is then assembled to at least one can end member (30) to form a completed shaped metal can (28). The ribs may either be arranged longitudinally, circumferentially, or both may be provided to form a grid structure.Type: GrantFiled: July 25, 1997Date of Patent: August 17, 1999Assignee: Crown Cork & Seal Technologies CorporationInventors: Zeev W.

Patent number: 5938056Abstract: An articulated hinged closure includes a lid adapted to be attached to a wide-mouthed container. The lid has a pouring aperture and a peripheral rim surrounding the aperture, which is initially plugged by a sealing member having upper and lower leaves interconnected by an integral articulated connector. The connector is a link having opposed upper and lower ends, and a flexible hinge at either end, the upper of said hinges connecting the link to the upper leaf, and the lower of said hinges connecting the link to the lower leaf. Each of said hinges is designed so that a respective end of the link binds against adjacent structure in such a-way that, as the lid is opened, the upper hinge eventually binds against the upper leaf, causing the lower hinge to pivot and bind againstr the lid and until it pries the plug out of the aperture.Type: GrantFiled: February 19, 1997Date of Patent: August 17, 1999Assignee: Crown Cork & Seal Technologies CorporationInventor: Xiaoli Ma

Patent number: 5934547Abstract: A spiral wound type composite container of the type that is typically used for packaging refrigerated pressurized dough products includes, as is typical in such containers, an inner liner, a body wall that is wound about the inner layer so as to define a butt joint, and a label member that is wound about the body wall so as to bind the body wall against expansion as a result of forces that are created by the pressurized contents of the container. As is also typical in such containers, the label member has a tab defined at one portion thereof and a predetermined lead path forming the tab so that a consumer can grasp the tab and tear the label member along the lead path, thereby removing enough of the label member from the body wall so that forces of pressurization will cause the body wall to separate and open.Type: GrantFiled: January 28, 1998Date of Patent: August 10, 1999Assignee: Crown Cork & Seal Technologies CorporationInventors: James Vaughn, Joseph Forte

Patent number: 5931331Abstract: A can end having an improved pour-type ecology opening mechanism includes a conventional can end wall that contains a score line that defines a displaceable panel. The score line includes an initial design rupture point, a radiused portion having a first tangent point and a second tangent point, and a main portion that terminates at a final transition point. The can end further includes a tab having a liftable heel portion and a tab nose portion, with the tab nose portion being positioned to apply downward pressure to the panel at a pressure point on the displaceable panel when the heel portion is lifted. The tab has a center line that is coincident with a radius of said can end wall. Advantageously, the pressure point is positioned a distance, taken in the direction of the center line, from the second tangent point of the radiused portion that is selected to prevent a buildup of force that would otherwise hasten propagation of separation along the main portion of the score.Type: GrantFiled: February 27, 1997Date of Patent: August 3, 1999Assignee: Crown Cork & Seal Technologies CorporationInventors: William A. Kirk, Michael C. Calhoun, David M. Hoffman, Jeffrey McFarland

Patent number: 5894041Abstract: A blank (2) is molded for the manufacture of a multi-layer preform (1). The blank possesses protrusions (5). After the protrusions (5) have been brought to a plasticised state under the action of heat, those surfaces that contain protrusions (5) are covered by a layer of plasticised material. The blank (2) becomes connected to the layer (6) in the area of the protrusions (5). After cooling of the preform created from the blank (2) and the layer (6), the blank (2) will be connected with the layer (6) by means of microweld positions (7) in the area of the said protrusions (5). With that, delamination of the preform (1) during further processing or use-will be effectively prevented.Type: GrantFiled: October 11, 1995Date of Patent: April 13, 1999Assignee: Crown Cork & Seal Technologies CorporationInventor: Stephen W.

Patent number: 5884790Abstract: A self-braking closure cap for a container, such as a soft drink container, of the type that has a threaded finish portion with at least one raised thread defined thereon includes a top wall portion and a side wall portion having a substantially cylindrical inner surface. The inner surface has at least one raised helically oriented thread defined thereon that has a predetermined pitch. Advantageously, a restrictor is provided for frictionally resisting unscrewing of the closure cap from a container finish portion by bearing primarily against one side of one of the raised threads of the finish portion. Since the braking is achieved by frictional engagement having a significant axial force component, instead of a radial force component, braking can be achieved with a minimum of radial force being exerted on the closure. This preserves the stripping torque value of the closure at an acceptable level without the need to add additional material to reinforce the closure against deformation.Type: GrantFiled: October 30, 1997Date of Patent: March 23, 1999Assignee: Crown Cork & Seal Technologies CorporationInventor: Thomas M. Seidita
