Abstract: Pressurization of containers with liquid nitrogen to impart container strength and content protection is effected by injecting a small quantity of liquid nitrogen before sealing the container by the methods and apparatus including a gas pressure system wherein liquid nitrogen is maintained by control means at a constant pressure with nitrogen gas being separated from liquid nitrogen before dispensing and a recirculating pump pressure system wherein liquid nitrogen from a second of two supplies is pumped through a conduit to a dispensing gun and surplus liquid and gas is returned to the supply.

Abstract: A container embossing apparatus includes a container-supporting embossing mandrel that has circumferentially-spaced, axially-extending ribs on the periphery that are engageable with a resilient forming mandrel or member so that crease lines are formed on the container during the embossing operation.

Abstract: An apparatus and method for the high-speed production of seamless metal container bodies is disclosed utilizing a reciprocating ram which forces a relatively shallow metal cup through a die assembly to iron the sidewall of said cup to form an elongated ironed container body, the ram is supported and critically-aligned by at least two stationary guide means along its length and a slide blank means rigidly secured to its rearward end, the slide block means having opposed hydrostatic pressure pads to provide constant critical alignment of the rear end of the ram and prevent misalignment of the ram relative to the die assembly to avoid producing container bodies of overly-inconsistent length.

Abstract: A cup feeding mechanism for a bodymaker includes a guide chute defining a vertical path with a stop located at the lower end of the path defining a transfer area. The stop has a specifically configured area for receiving each cup and defining a fixed position for the cup in the transfer area. A drive member is reciprocated transversely of the path and picks up cups from the transfer area and positively drives them into alignment with a ram that extends perpendicular to the axis of the path so that the cups are maintained in accurate alignment with the ram prior to being transferred through the bodymaker.

Abstract: A modular system for producing triple-necked open ended containers includes three substantially identical necking modules each having the same frame and identical rotatable turrets which have a plurality of identical necking stations around the periphery. Each necking station includes an annular necking die and a platform and punch which are cam-operated to move towards and away from each other and are maintained in engagement with the cams by pressurized fluid. Each necking station also has a container pressurizing means in the form of an annular chamber which acts as a holding chamber prior to transmitting the pressurized fluid into the container.

Abstract: A container for vacuum packaging of products includes an outer container and an inner liner which conforms generally to the configuration of the outer container and is secured to the upper open end thereof while the remainder of the container and liner are unattached. A vent is provided between the atmosphere and the space between the container and liner so that the liner can expand and collapse as differential pressures are applied to the product sealed in the liner by a plastic film secured open end thereof.

Abstract: A container end formed from metal having an approximate thickness of 0.0120 inches which is capable of withstanding at least 90 psi buckle pressure and at least 60 psi rock pressure is disclosed herein. A container end panel includes a peripheral curl surrounding a substantially flat center panel with a countersink therebetween. The countersink has inner and outer substantially flat walls that are interconnected by an arcuate portion that has a radius of approximately 0.030 inches and the inner wall is connected to the periphery of the center panel through an arcuate portion that has a radius of approximately 0.025 inches. The outer flat wall has a length which is greater than the length of the inner flat wall and the outer flat wall defines an angle of less than five degrees with respect to a plane that extends perpendicular through the center flat panel. The inner flat wall has a length to locate the lower edge of the countersink about 0.

Abstract: A precoated stock material for use in forming a drawn and ironed container and a method of forming such container is disclosed herein. The stock material initially has a layer of lubricant applied to one or both surfaces of the metal base with the lubricant consisting essentially of a fatty acid ester of a mono or polyhydric alcohol and having a distribution of less than 3 mg./in..sup.2. The method contemplates applying the layer of lubricant to a metal stock, such as aluminum, black plate or tinplate, cutting a disc from the metal stock, and transforming the disc into a drawn and ironed container without additional lubricant being applied to the tooling.

Abstract: A drawing and ironing assembly including a punch movable along a path having a plurality of spaced ironing die assemblies with the last of the ironing die assemblies having twin spaced lands, the diameter of the second twin land is slightly greater than the diameter of the first land to produce a very small amount of ironing.

Abstract: A color monitoring device includes a mechanism for removing containers from a path and accurately positioning a preselected area with a color monitor. The color monitor produces an output signal representative of the area being monitored which is amplified and fed to a computer where it is compared with reference signals. If the output signal is outside prescribed limits, the container is rejected, and if it is within prescribed limits, the container is returned to the path. A shuttle mechanism is activated by the computer and automatically removes a container from the path while returning a previously inspected container to the path. Stepper motors are used to vertically and horizontally position a selected point in front of the colorimeter.

Abstract: A method and apparatus for providing uniform corona bonding between and across the width of a plurality of layers of material each having a generally uniform thickness and width whereby, if desired, the plurality of layers may be easily and uniformly separated. Uniformity of bond is achieved by configuring the outer ends of an otherwise straight electrode, placed at an optimum effective bonding position, in proportion to the higher corona energy levels found to occur at the ends of the corona electrode bar.

Abstract: A dome depth detector for a drawn and ironed container having a domed end wall includes a frame that has a first rotatable means supported thereon for guiding the containers along a path, a guide surface on one side of the path on the frame, and a rotatable member on the opposite side of the path which has means engageable with the domed end wall for sensing the depth of the domed end wall and indicating a shallow dome below a preselected minimum. The detector also has a container for counting the number of containers moving along said path.

Abstract: A stock material for producing seamless containers from a black plate base includes applying a layer of insoluble crystalline phosphate to each surface of the black plate and subsequently producing a thin film of organic lubricating material on the exposed surfaces of the phosphate layers so that a drawn and ironed container can be produced from a flat blank without the use of any additional lubricants during fabrication. The weight of the phosphate layer for each surface of the black plate base is preferably less than 100 milligrams per square foot, while the weight of lubricating film is on the order of 70 to 360 milligrams per square foot. In the preferred embodiment, the phosphate layer is preferably in the range of 20 to 35 milligrams per square foot, and the lubricant layer is on the order of 70 to 180 milligrams per square foot.
