Abstract: This relates to the forming of packages by thermoforming a web which is of a laminated construction. By forming the web as two separate webs, particularly when one of the webs may include sterile components, the number of splices which must be made under sterile conditions is greatly reduced as compared to the number of splices which may be conventionally formed.

Abstract: This relates to the blow molding of containers wherein the containers are formed of biaxially oriented plastic material. A multi-sided hollow member is blown within a convention blow mold using a conventional type of preform. Each side, when severed from the top and bottom of the hollow member and from each other forms a tray or box like container having a bottom, side walls and a peripheral sealing flange. The efficiency of the container from a weight to capacity standpoint is at a maximum due to the biaxial orientation of the plastic material.

Abstract: This relates to the forming of a blow molded polyester container wherein a bottle having a conventional upper neck portion and an intermediate body is provided with a lower portion which includes an annular seaming flange which is integrally connected to the lower end of the body and wherein, with the exception of the seaming flange, the lower portion is removed and the bottle is closed by a separately formed bottom double seamed to the lower end of the body utilizing the annular seaming flange. During the interim between the removal of the bottle lower portion and the application of a separate bottom, the bottle is fully open so as to be readily commercially interiorly coated with a barrier coating. The separately formed bottom may be readily formed of metal and may be so constructed as to provide a large diameter base for supporting the bottle in upstanding position. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Abstract: This relates to the hot packing of products such as food within cans. In order to permit the use of less strength cans than heretofore considered practicable, it has been necessary prior to the closing of such hot packed cans to introduce a pressurizing media such as liquid nitrogen being preferred. It is here proposed to so apply the closing end unit to the filled can so as to permit the end unit to function as a piston and to effect a pumping action when it is applied so as to permit the internal pressurization of the newly filled can without requiring any additive.

Abstract: This relates to the cutting or trimming of a blow molded polyester resin article utilizing a CO.sub.2 laser. The article is axially positioned and rotated while the laser beam is focused and concentrated on a preselected portion of the article. The laser beam beneficially vaporizes the polyester resin in the cutting thereof as opposed to forming a dust. Further, the action of the laser is one wherein a certain melting occurs so that the resultant cut edge of the retained part of the article is rounded and sealed.

Abstract: This relates to the mounting of a label magazine in a manner wherein labels carried by such label magazine may be rotated or slewed about a line extending axially of the label magazine through the center of a label. The slew control device is used to effect such rotation and thus orientation of a label so as properly to position the label for transfer. In the preferred usage of the slew control device, each label is transferred into a blow mold half and proper orientation of a label with respect to a blow mold half cavity is obtained utilizing the slew control device. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Abstract: A plastic jar is formed by blow molding a combination adapter and jar and thereafter the jar is cut from the adapter utilizing a laser beam. The jar may be blow molded from a preform which is of an injection molded laminated construction so that the wall of the jar is formed of plural layers. The head generated by the laser beam will melt and bond together these layers as opposed to permitting delamination as would occur should the jar be cut from the adapter by a knife or the like. The cut surface of the jar forms the mouth defining surface of the jar and it is preferred that the cut be inclined at a slight angle to a plane normal to the axis of the jar. Damage to the diametrically opposite surface of the jar by portions of the laser beam being utilized for cut off passing through the jar is prevented by a pressurized gas supply tube which is in the path of the laser beam and serves as an absorber for stray rays. This abstract is not to be construed as limiting the claims of the application.

Abstract: This relates to a closure which may be fully lockingly engaged on a container neck finish in sealed relation yet may be easily released and which is replaceable to effect resealing of the contents. The closure includes primarily a cap-like closure element and a retaining ring, with the closure element having a skirt with a free end and depending from the skirt free end radially inwardly displaceable locking means which will lockingly engage in a peripheral groove in a container neck finish and which are forced into such a groove by a retaining ring which is provided with a locking groove for receiving in locking engagement radially outer portions of the locking means, whereby the retaining sleeve is locked to the closure element and the closure element is locked to the container neck finish.

Abstract: This relates to a can, preferrably formed of aluminum, which may be formed by a drawing process and which is so constructed wherein it may utilize wall thicknesses less than those which are presently commercially permissible so as to be suitable for the packaging of food products and the like which are either hot filled or subject to retorting and still commercially compete with three-piece steel cans. A primary feature of the can is the elimination of the customary double seam securing the end unit to the can body and replacing the same with telescoping of portions of the can body and end unit and providing an adhesive bond therebetween with the adhesive bond being enhanced by the reaction of the can body and end unit under conditions of internal pressure and internal vacuum due to the radial compression of the adhesive forming the adhesive bond to increase the shear strength of the adhesive.

Abstract: This relates to a pneumatic feed system for moving a labeler head of a labeling apparatus for depositing labels in mold halves of a blow molding apparatus. The relatively heavy labeler head must be rapidly accelerated and then rapidly decelerated and at the same time moved sufficiently so as to provide for a large number of back and forth cycles per minute. There is provided in association with compressible shock absorbers a pneumatic system including a high pressure supply and a low pressure supply together with throttle valves such that the gas in the unpressurized end of the cylinder is rapidly compressed near the end of the stroke to function as a shock absorber and further, the cylinder is of a much larger diameter than that required for moving the labeler head so as to permit for the rapid acceleration as well as the rapid deceleration.

Abstract: This relates to closure assemblies for containers which are subject to tampering. This particularly relates to closure assemblies of the type which include a lever type actuator wherein the lever must be lifted to apply leverage to a closure plug portion to facilitate opening of the closure assembly. Such levers are customarily retained in place by rivets which include frangible portions. This particularly relates to the configuration of such rivets and the details of the lever wherein, once the lever has been pried from its original position and disengaged from the rivet, the lever or an end portion only thereof tilts upwardly due to the non-returnability of the rivet through its original opening thereby to present a visual indication of tampering which can be readily ascertained.

Abstract: This relates to a closure for containers, particularly containers such as containers for beverages and the like which are packaged under pressure. The closure includes an outer retaining ring portion and an inner sealing plug portion which are preferably initially molded as a unitary product, but wherein the sealing plug portion is connected to the ring portion primarily by a rupturable connecting line. The retaining ring portion is interlocked with an extreme end of the neck finish of a container and the sealing plug portion is interlocked in sealing relation with an internal shoulder of the container neck finish, which shoulder defines a pour opening. The sealing plug portion is retained in association with the retaining ring portion by a hinge strap which is elongatable under tension. The sealing plug portion is also provided with a vent opening which is normally closed by a vent valve which is held in its closed position by internal pressure and which is movable manually to a vent position.

Abstract: An adhesive composition for bonding polished metal surfaces to vinyl chloride polymer coated metal substrates is disclosed which is comprised of a thermoplastic vinyl chloride polymer resin, a thermosetting epoxy resin normally incompatible with the vinyl chloride polymer resin and an amount of an acrylonitrile/butadiene/styrene copolymer which imparts compatibility between the epoxy resin and the vinyl chloride polymer.

Abstract: The susceptibility to color and flavor loss of liquid containing comestibles due to oxidative deterioration during storage is reduced by placing the comestible in the cathode compartment of an electrochemical cell in which the compartments of the cell containing the anode and cathode are separated by a cation permeable membrane and the anode compartment contains a highly dissociatable, non-oxidizable inorganic acid electrolyte, and thereafter subjecting the comestible to a high density current for a short period of time sufficient to generate hydrogen at the cathode to remove oxygen from the comestible but insufficient to effect a substantial chemical change in the comestible. The deoxidized comestible is then stored in a hermetically sealed container in which air is substantially absent.
