Abstract: A tamper-proof cap and neck assembly made of stretchable plastic material in which the neck has portions fitted within and about a short metal neck portion of a container which serves as a rigidifying back up for the plastic neck and for a locking shoulder on the neck to provide a deflection resistant structure and thereby prevent a tamper-indicating ring connected to the cap from slipping off the shoulder without tearing upon initial unthreading of the cap. This rigidified structure also facilitates application of the tamper-indicating ring during initial threading of the cap onto the threaded neck at which time the ring is stretched over the shoulder by a capper bead which engages force-transmitting posts integral with the ring for forcing the ring over the locking shoulder, the band being stretched between the posts and extending beneath the shoulder as chordal segments.

Abstract: In the manufacture of fiber-reinforced cellulose casing wherein a paper tube is passed downwardly over a mandrel, impregnated with viscose and subjected to the action of a coagulating liquid to regenerate cellulose, a gas stream is flowed upwardly within the tube as the tube is passed over the mandrel, the gas stream pressure being sufficient to maintain the cylindrical dimensions of the tube but insufficient to cause a measurable change in the dimensions of the tube walls whereby contact of the internal surface of the impregnated tube with the mandrel is reduced or substantially eliminated.

Abstract: The interior side seam areas of tinplate can bodies exhibit improved resistance to corrosion by sulfur containing foods packaged therein when the side seam is soldered with a tin solder comprised of 0.1-0.5 percent by weight indium, 0.1-0.5 percent by weight bismuth, the remainder being tin.

Abstract: A mold provided with cutter means movable relative to the other elements of the mold to sever an extension portion of a hollow article formed in the mold from the remainder thereof while the article is in the mold and without effecting substantial movement of the article relative to the mold.

Abstract: A closure for a container wherein a tape having a metal part and thermoplastic material which is applied to the container wall and heated. Most of the material is squeezed out from between the metal part and the wall into a rib which is formed during application. The material in the rib has an isotropic structural characteristic since the rib formation provides a region into which the excess material is directed minimizing the shearing effect of the flow of material along the interface with the container wall. Also the rib reinforces the tape in the critical region to resist pressure of gasses in the container when used to contain carbonated beverages.

Abstract: To reduce the number of oversize sausage links created during linking of stuffed regenerated cellulosic casings, the casing, before stuffing, has applied to the external walls thereof an aqueous dispersion containing a material which imparts a low coefficient of friction to the casing.

Abstract: Stable dispersions of propylene polymer resins which can be fused to form smooth, uniform, pinhole-free coatings are prepared by admixing the resin in particulate form having a median diameter of 0.1-50 microns with an organic liquid having a boiling point above 300.degree. F. and a density approximately equal to the resin, the resin being insoluble and dispersible in the liquid at room temperature and soluble in the liquid at temperatures above 350.degree. F.

Abstract: A non-detachable tab adapted to be secured to the end panel of a container which comprises a securing lug formed from the sheet metal of the tab, the lug having an attachment to the nose portion of the lug in an area which has not been work hardened and also which has been formed to provide several axes of hinging and thereby increasing the number of times that the tab can be hinged back and forth without breaking off.

Abstract: A composite container comprising a rigid cylindrical sidewall, an end closure integrally attached to the sidewall, a product-compatible liner disposed within said sidewall, and a cutter element, carried between the sidewall and the liner, for rupturing the liner to permit passage of product therethrough. The end closure is formed of a distal end portion of the sidewall folded into a plurality of interconnected triangular segments disposed transverse the principal axis of the container and arranged to be reformable into a pouring spout. A grasping element is attached to both the cutter element and the end closure, such that the end closure may be opened, the pour spout erected and the liner ruptured in a single operation.

Abstract: A sausage casing surface formed from regenerated cellulose is exposed to a source of surface activating energy to an extent sufficient to induce a change in the surface whereby the casing will adhere to a sausage emulsion encased therein and follow the shrinkage of the sausage during processing.

Abstract: Mineral fillers reactable with acids such as metal carbonates such as CaCO.sub.3 are rendered more compatible with polyolefin resins such as polyethylene by first reacting the filler with a long chain carboxylic acid to form a surface film of the acid. The acid reacted filler is contacted with a vinyl ester of the acid which is then polymerized in the presence of a free radical catalyst such as benzoyl peroxide to encapsulate the acid reacted filler in a coating of the polymerized ester.

Abstract: A ring type calibrating cage for confining a metal container shell just prior to and during seam welding. The cage comprises a series of strategically located rings through which the can body is fed. These rings are of narrow width reducing friction drag and being optimally positioned to accurately hold the can body in cylindrical shape with overlapped edge portions particularly when these edge portions enter into the welding nip.

Abstract: An improved child resistant end closure wherein the pull tab for an easy opening end is mounted within a panel bead; the tab being fastened by the rivet to a tear-out portion of the end panel. The tear-out portion is adapted to be pulled outwardly about a hinge line which intersects the bead. The bead is reduced in depth at the intersection with the hinge line and formed to permit the bead to fold in such manner as to resist sudden flip-out of the tear-out portion which in the previous designs has caused splashing out of the contents in the container.

Abstract: This invention relates to an artificial sausage casing and a process for making the casing. In making a regenerated cellulose casing an oxazoline wax is incorporated into viscose in a proportion from about 1 - 20% by weight of the cellulose content in the viscose, the oxazoline impregnated viscose extruded into a tubular casing, coagulated, and the cellulose regenerated. The casing has excellent handle, flexibility, and peelability from sausages processed therein.

Abstract: This invention relates to an artificial sausage casing of regenerated cellulose having a coating composition applied over the internal surface thereof which exhibits excellent meat release from sausages processed therein under high speed mechanical peeling and has improved resistance to strand breakage and pinholing during shirring and meat processing, the coating being an admixture of a water-soluble cellulose ether, a partial fatty acid ester of sorbitan or mannitan and a water-soluble polyalkylene glycol ether having the formula RO(--C.sub.2 H.sub.4 O).sub.n --H wherein R represents long chain alkyl radicals having 8 to 16 carbon atoms and n is an integer from 4 to 40.

Abstract: A tab for an easy open end which comprises a rivet securing the tab intermediate its ends to the end panel, the tab having a nose end which is adapted to be pressed downwardly upon lifting of the opposite lift end of the tab against a tear-out portion of the end panel and to push the same inwardly. The invention is directed to forming the nose and the lift end of the tab in such manner that both ends of the tab are maintained in constant contact with the container end while it is attached intermediate its ends to the container end panel in order to prevent rocking of the tab and thus producing a fatigue failure in the scored area which is adjacent the tab.
