Abstract: A coating composition and container coated with said composition comprising a water insoluble organic coating and having incorporated therein zinc oxide and an alkaline earth metal material in an amount sufficient to effect green color retention of green vegetables.

Abstract: A process for improving the organoleptic properties of canned green vegetables wherein vegetables blanched with a highly alkaline solution are suspended in a brine having an alkalinity adjusted to between about 25 to about 75 milliequivalents of hydroxyl ion in a hermetically sealed container internally coated with an organic coating filled with an alkaline earth compound such as MgO, the vegetables being sterilized at 250.degree.-300.degree. F. to an F.sub.o value of at least 6 whereby the original color and flavor of the vegetables are retained.

Abstract: A welded seam between overlapped edges of sheet material wherein the sheet material is heated to a temperature below the melting temperature and is forced together under high pressures to form a forged weld. The thickness of the sheet material in the weld area is reduced from double thickness to a thickness approaching a single thickness, with the weld interface being diagonally disposed. The weld is effected by grain growth across the interface such that the particular line along which the meeting surfaces of the metal are welded together is unobservable upon etching a cross section thereof and with magnification on the order of 100X. The heating is effected by applying to opposing edge portions which are to be overlapped and welded a high frequency current which effectively reduces heating to edge portions only of the metal with the heat effected area being in the vicinity of 0.1 inch.

Abstract: A container for pressurized products wherein the container is formed of first and second container halves joined in a generally mid-height peripheral seam. Under abusive handling, the seam could open and a rupture type failure may occur. A shrunk plastics material film wrapper is applied along the central portion of the container in overlying relation to the peripheral seam and serves to permit controlled venting of the pressure from within the container in the event of such seam failure of the container per se.

Abstract: A two-piece can wherein the can body is of a drawn and wall ironed construction having an integral bottom with the bottom being in the form of a reinforced structure including alternating projecting ribs and recessed areas. The top of the can is closed by a conventional end unit. In use, the bottom becomes the top and the bottom is provided with a dispensing opening which is closed by a sealing tape. There are several embodiments of the end structure with there being different positions for the dispensing opening therein and different relationships of the sealing tape with respect to the end structure.

Abstract: An easy opening closure for pressurized fluids and a method of making the same. The container has an end panel with multiple small openings and a tape strip of plastic or plastic coated metal foil is secured to the panel by a heat activated adhesive in a way by which the plastic is extruded into the openings to form hollow bosses each defined by a peripheral annulus or torus formed into the respective opening and at least partially bonded to an uncoated raw edge of the opening, the boss having a disk-like center portion and the surrounding annulus providing a thick cross-section resisting doming of the areas of the tape covering the openings and inhibiting the development of incipient cracks and their propogation resulting in premature peeling of the cohesive bond.

Abstract: A method for high speed sinter molding having endless chains mounted side by side. Mold halves are attached at spaced intervals down the chains. The paired mold halves come next to each other to form a female mold into which is deposited a polymeric material. A treating core extends inside the mold and as the mold traverses its path, it surrounds the core and the core deposits polymeric powder, heats the polymeric powder, and then cools it. At the end of the mold path, the finished article is ejected and is ready for the next operation.Another embodiment of the same essential process is to place the paired mold halves in juxtaposition as they moved down over the core. This will result in the fabrication of a continuous conduit. A container may be fabricated by using hollow mold halves with heating and deposition accomplished before the hollow mold halves are pressed together to form a hollow container.

Abstract: This disclosure relates to a method of fabricating tubular bodies having at least one closed end by advancing material along a predetermined path of travel in a predetermined direction, forming the material into a tube during its advancement, placing a closure in-line with the advancement of the tube, and utilizing the motion of the advancing tube to assemble the latter with the closure.
