Abstract: A plastic closure cap for containers wherein the closure cap is threadedly engaged on the container neck finish and has a tamper indicating band which is locked beneath a transfer bead on the container neck finish. The tamper indicating band is simply in the form of a plurality of segments which extend between circumferentially spaced bridges and which normally are curved radially inwardly. The tamper indicating band segments, however, will deflect radially outwardly and change shape so as to freely pass over the transfer bead as the closure cap is being applied to the container neck finish. After the tamper indicating band segments pass beyond the transfer bead, the segments snap back to their original positions due to tension and are locked beneath the transfer bead.

Abstract: This relates to a dispensing cap including a cap body and a cover which are connected together by suitable hinges so that the cover may swing between a fully open position and a fully closed position. In association with the hinges, there is a strap which connects a bendable wall portion of the cover to the cap body. The strap, in the open position of the cover, is located on one side of hinge centers and as the cover is swung towards a closed position, the strap passes through an overcenter position where a greater length of strap is required, thus effecting bending of the cover wall portion between the hinges to provide a spring effect. In the closed position of the cover, the strap is on the other side of the hinge center and bending of the cover wall portion is held to a minimum.

Abstract: A plastic container adapted to be peelably heat sealed with a lid, the container having an integral peripheral flange extending outwardly from its upper edge to which the lid may be peelably heat sealed, the lid contacting surface of the flange being comprised of a peel mixture of polyethylene, and ethylene/vinyl acetate copolymer and a butene-1 polymer.

Abstract: This relates to a device for identifying a product which may be placed within a carton. Most particularly, it relates to cartons for drinks served at a fast food establishment. The carton is formed of a paperboard having a plastic facing both interiorly and exteriorly. Identifying indicia is printed on the carton adjacent a corner of the carton and tabs are defined by cut lines which extend through the outer plastic layer and terminate within the paperboard core with the paperboard being radially delaminatable. Free ends of the cut lines remote from the corner are joined by a fold line. When the carton is folded to define corners, the tabs, which extend across the corners, automatically have their starting ends displaced from the plane of the paperboard so as to be radially grippable and displaceable.

Abstract: This relates to a tamper-evident closure cap having a tamper-evident structure for locking engagement beneath a transfer bead of a container neck finish. The closure cap includes a customary tamper-evident band which is of a diameter to freely pass over both external threads and a transfer bead of a container neck finish. In order that a bridge rupturing pressure may be applied to the tamper-evident band, there is provided a separate lock ring of a size to engage beneath the transfer bead while having an outer portion overlying the tamper-evident band to transfer pressure thereto during the removal of the closure cap. The lock ring is radially expansible to freely pass down over the threads and transfer beads during the application of the closure cap.

Abstract: The closure cap is provided with an extension of the skirt thereof with the skirt extension having formed therein lines of weakening and having at a lower end thereof an anchoring band which, when the closure cap is applied to a container neck finish, will permanently anchor the closure cap to the container, thus preventing littering by the separate dispensing of the closure cap. The skirt extension is provided with a line of weakening arrangement which, when a cap portion is removed from the container, will rupture and which will define a tethering strap which permanently retains the cap portion to the anchoring band while permitting any required rotation and axial movement of the cap portion to facilitate cap portion removal and product dispensing.

Abstract: This relates to a tamper indicating cap which includes a conventional closure of the threaded type. The closure is provided with an injection molded member which includes an inner ring that overlies and is bonded to an end panel of the conventional closure and an outer ring which is telescoped over and extends beyond a skirt of the conventional closure. The inner ring is joined to the outer ring by a first set of breakable bridges and a second set of bridges in the form of diagonal links. When the outer ring is turned in a cap removing direction, the two rings move relative to one another sufficiently to cause rupture of the first set of ribs to indicate tampering. The diagonal links then transmit cap removal torque to the center ring and from the center ring to the shell of the conventional closure.

Abstract: This relates to a carrier for cups or containers. The carrier is formed from a flat sheet of plastic material and has a pair of openings therein on opposite sides of a transverse bar for receiving upper intermediate portions of cups. Each of the openings is defined by a peripheral strap which will tightly engage an intermediate upper portion of a vertically tapered cup. Further, generally surrounding at least one of the openings is a carrying strap defined by a C-shaped cut which also defines the article engaging strap for that opening. In one form of carrier there are two carrying straps and in another form there is a single carrying strap.

Abstract: An injection molded plastic closure having a tamper indicating portion. The tamper indicating portion includes a tampering indicating band which is attached to the skirt for radially outward hinging by a plurality of bridges. The tamper indicating band is subject to splitting whereby it may expand outwardly and clear a container neck finish. The tamper indicating band remains attached to the closure and the splitting thereof indicates tampering. Bridges attaching the tamper indicating band to the closure skirt are of sufficient cross section to have the required structural strength to prevent separation of the tamper indicating band from the closure skirt and at the same time permit injected molten plastic to freely flow from the closure skirt into the tamper indicating band.

Abstract: This relates to blow molded containers, and particularly to the formation of blow molded containers formed of a plastic material which is subjectable to a high degree of biaxial orientation for maximum strength. Two containers are formed in each blow molding operation with each container having throughout the stress areas thereof a high degree of biaxial orientation. A container may be in the form of a bottle having an as formed open bottom which is closed by a metal end unit seamed in place. Other containers will have open mouths closed by conventional closures including metal end units which are seamed to the container body or by closure caps which may be releasably interlocked with the neck finish of the container in several known modes. In every instance the containers are formed with a minimum of scrap. 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 a bottom construction for a composite container wherein the container body is of a composite construction such as a wound paper tube having a plastic material liner. The bottom construction includes a generally cup-shaped closure element formed from a plastic material sheet which is molded in situ within the bottom end of the tubular body with the plastic material being heated to a molding temperature with the temperature being such that the plastic material of the closure will self-bond to the plastic material of the liner. The closure is of a generally hat-shaped configuration and includes a central cup portion which is telescoped within the end of the tubular body and which is then provided with a reinforcing disk, after which the extreme end portion of the tubular body is curled or rolled radially inwardly to abut against the underside of the reinforcing disk to complete the bottom construction.

Abstract: This relates to the base configuration of a biaxially oriented blow molded thermoplastic resin container. It has been found that by assigning more space to the ribs between adjacent legs and feet, during the blow molding of a preform, there is proportionally less thinning of the material of the preform in accordance with the greater width of rib, thereby providing greater strength in the high stress area of the base structure with a resultant lesser failure due to stress cracking.

Abstract: This relates to a blow molding machine of the type for blow molding large articles such as containers of the one gallon to five gallon size from a parison in the form of an extruded plastic material tube. The machine is of the rotary type and has a plurality of stations each carrying a mold unit of which one half is fixed and the other is mounted for radial movement between open and closed positions. The main shaft of the machine is of a large diameter and is tubular so that the necessary manifolding for gas and coolant supplies may be readily incorporated in the main shaft in an entirely different manner from that heretofore utilized. Also, among other features of the machine, is the provision of hollow spokes which serve not only to support outer mold halves for radial movement, but also serve as manifold accumulators for the necessary operating gases.

Abstract: This relates to the strengthening of the base of a blow molded plastic bottle and like container wherein the container base is of the type having generally hemispherical portions alternating circumferentially with projecting feet defining portions. It has been found that by roughening the surface of the base, particularly the lower central portion thereof, the base is greatly strengthened. The base is formed by blow molding in a blow mold base portion which has been roughened by shot peening.

Abstract: This relates to an apparatus for injection molding preforms for beverage bottles wherein a minimum cycle time is involved. Cores over which thermoplastic material is injection molded to form preforms for use in the blow molding of bottles are provided in sets and carried by a rotary turret so that as soon as the injection molded thermoplastic material has sufficiently set to permit its transfer with its associated core out of an injection mold cavity, the apparatus may be actuated to remove first injection molded preforms and thereafter immediately present a new set of cores to the injection mold cavities. This provides ample time for the cooling of the preforms so that when removed from the cores they will not be unduly deformed. In accordance with the feasible use of the apparatus, plural preforms, on the order of twenty-four and greater, may be formed with a cycle time on the order of 10-12 seconds.

Abstract: This relates to laminated preforms, the method of forming such preforms and products which may be beneficially formed utilizing such preforms. Most particularly, this relates to a preform which has formed as part of the injection molding thereof two layers of barrier material which are disposed within two layers of thermoplastic resin and having received therebetween a solid core of thermoplastic resin. The specific method of forming the preform permits the barrier material layers to be of a greatly reduced thickness as compared to such layer thicknesses permissible in the past, with the result that the barrier material layers in the blow molded articles are of a thickness recognized to be acceptable for the barrier function. The barrier material layers may be selectively terminated along the length of the preform so as to permit portions of the resultant blow molded article to be removed and reused. This abstract is not to be construed as limiting the claims of the application.

Abstract: This relates to a closure unit of the type including a closure member lockable in place having secured thereto a lever for effecting unlocking of the closure member. The closure unit has a tamper indicating feature in the form of a rivet projecting from the closure member and being received in a ring member releasably integrally formed with the lever. The rivet has been modified to have a blind hole opening through the underside of the closure member for presentation to the interior of an associated container whereby, should the rivet be severed from the closure member, the blind hole will open to the atmosphere and permit a venting under high pressure of the interior of the container.

Abstract: This relates to an improved aerosol container of the type wherein the dome is formed separately from the body and is secured to the body by a conventional double seam. The aerosol container is improved by squeezing the double seam radially inwardly so that it is, in effect, necked in and may also be tilted to correspond generally to the dome profile. In the ultimate condition the upper part of the body is also tilted radially inwardly and the chuck wall upper portion contacts the dome above the annular countersink completely to close the countersink.

Abstract: A container closure formed from a thermoplastic polyolefin, e.g. polypropylene, which has been molded and adheres simultaneously to a coated foil, e.g. an aluminum insert, to which a conventional plastisol gasketing compound may be adhered to provide a hermetic container seal under hot fill and retort conditions. In order to facilitate adhesion to both the polypropylene closure panel and the PVC plastisol gasketing compound, a dead soft aluminum foil web was first coated on one side with an organosol utilizing a gravure coater, after which the coated web was passed through an oven. The partially coated web was then coated with a primer dispersion again utilizing a gravure coater, after which the coated web was passed through a second oven. A layer of polypropylene homopolymer was applied to the primer and inserts were die cut from the resultant web. The inserts were incorporated in a closure injection molding apparatus and a plastic closure injection molded thereabout.

Abstract: A polyolefin container is disclosed which is hermetically sealed with a complementary lid extending across the open container the opposed faces of the container surface and the lid being bonded together by a peelable, heat seal layer intermediate between the opposed faces. The heat seal layer is comprised of a mixture of a particulate filler and first and second polyolefin resins, the second polyolefin resin having a melt flow rate at least about three times greater than the melt flow rate of the first polyolefin resin.
