  • Non-detach easy opening container unit
    Patent number: 4289251
    Abstract: This relates to an easy opening container unit wherein a panel of a container is provided with a first line of weakness defining a first displaceable panel portion which, when displaced, defines a dispensing opening in the container. A second line of weakness extends from the first line of weakness and defines a second displaceable panel portion to which an opening tab is secured with the second displaceable panel portion functioning as a hinge element for the opening tab. the arrangement of the lines of weakness permits the use of a substantially rigid tab which permits a greater leverage advantage while at the same time minimizing tab failure.

  • Adhesive application of two-part container
    Patent number: 4280268
    Abstract: A container and method of adhesive bonding of two telescopic container halves wherein each container half has a cylindrical body, the inner container portion being circumferentially loaded to temporarily reduce its diameter and being forced in centered relation to the outer portion into a bead of adhesive laid in the interior of the outer portion to coat the raw edge on the inner portion, the inner portion shearing through the adhesive without wiping it off from the interior of the inner portion and thereafter the hoop stress on the inner portion being relieved so it springs out and squeezes excess bonding material from between the inner and outer portion and thus obtains thin film adhesive bond with good stress shear characteristics while holding the film in compression therebetween during curing or setting of the adhesive.

  • Easy-opening container with non-detach tab
    Patent number: 4276993
    Abstract: An easy opening container having an end panel with push-in section and a non-detachable tab secured to the end panel and formed with a uniquely shaped lift end portion having an aperture therein sufficient to admit the nodes of the user's grasping fingers but of a size less than would permit inserting a finger therethrough and the novel construction of the tab and presenting a finger placement limiting edge which is adapted to position the fingers of the user such as to prevent the user's fingernail from being broken in attempting to open said container.

  • Easy access tab for vacuum packed products
    Patent number: 4266688
    Abstract: This invention relates to an end unit of the easy opening type particularly adapted for use in a vacuum packed container. The end panel of the end unit is provided with doming which permits the associated tab to be slightly lifted before a rupturing force is applied with the tab. The particular shape of the dome provides for the necessary doming without an undue stressing of the already scored end panel.

  • Necked-in aerosol container-method of forming
    Patent number: 4261193
    Abstract: An apparatus and method for forming integral domed can bodies for aerosol cans. The apparatus is in the form of plural sets of tools, each set of tools including an inside tool and an outside tool so related as progressively to reduce the diameter of an end portion of the tubular body and in doing so gradually increasing the axial extent of an intermediate frustoconical portion. Each frustoconical intermediate portion is increased in extent axially by seating the previously formed portion on the inside tool and then shaping the blank on that same surface, whereby there is no interruption or stepping of the formed frustoconical intermediate portion of the blank.

  • Method of increasing the wall thickness of a bottom structure of a blown plastic material container
    Patent number: 4261948
    Abstract: This disclosure relates to an unexpected increase in the strength of a bottle bottom of the champagne type by the addition of ribs internally of the preform when the preform is axially stretched prior to the blowing thereof within the blow mold. Most particularly, by adding internal ribs to the interior surface of the bottom defining portion of the preform, the preform has the bottom forming portion unduly strengthened against shrinkage in wall thickness when the preform is axially lengthened through the use of a stretch rod. The net result is that the stretching of the preform and the thinning of the wall is held to a minimum in the bottom forming portion of the preform and is transferred primarily to the body forming portion of the preform where lesser wall thickness does not unduly detract from the strength of the bottle.

  • Reverse spray electrostatic air/powder stripe applicator
    Patent number: 4259923
    Abstract: A powder applicator for applying powder in a stream to side seams of container bodies. The powder is directed towards an associated nozzle entrained in a carrier gas. However, as the gas entrained powder approaches the nozzle, it passes through a centrifuge section of the supply tube wherein the powder is separated from the gas and is directed against a radially outer portion of a return bend which extends through an arc on the order of 180.degree.. As a result, the powder is directed to the orifice of the nozzle as a continuous dense stream with the gas being in a layered relation with respect to the powder.

  • Press structure having shiftable stop
    Patent number: 4258562
    Abstract: A press structure wherein die pads are movable within die sleeves and wherein the die pads are recessed within the die sleeves initially for receiving material slugs. A suitable mechanism is provided which permits the die pads to be returned to positions beyond their starting positions so as to effect the complete removal of a formed article from its respective die sleeve to facilitate transverse removal of each formed tubular body. The stop mechanism next functions to move the die pad back to the original starting position ready to receive thereon another material slug.

  • Two-piece hot runner manifold
    Patent number: 4256140
    Abstract: This relates to a hot runner manifold for distributing thermoplastic melts from a plasticizer to plural cavities of a mold. The manifold is formed in two parts which include a plate and a ring which are joined along a central parting line in a manner wherein all of the sprue and runner portions may be readily and accurately machined. The ring is shrunk in place on the plate and has an interference fit which is sufficient to prevent separation of the ring from the plate during normal operating conditions without the use of any fasteners.

  • Plastic container with a generally hemispherical bottom wall having hollow legs projecting therefrom
    Patent number: 4249667
    Abstract: This disclosure relates to improvements in the cross section of a bottom end of a plastic bottle suitable for packaging liquids under internal pressures. The bottom end is primarily one which includes a generally hemispherical bottom wall having projecting therefrom in circumferentially spaced relation hollow legs terminating in supporting feet. The bottom end is stiffened against creep of the plastic material over a period of time under the influence of the internal pressure by changing the configuration of the bottom wall from that of a hemisphere to one which includes a configuration of straight line sections and curved line sections when viewed in radial cross section along the axis of the bottle.

  • Magnetic bonding of tabs
    Patent number: 4248653
    Abstract: An apparatus and method for applying metal foil-plastics material film laminate pull tabs to coated container units. A high frequency electrical energy force field is set up and induced into the metal of the pull tab with the resultant heating of the metal and the subsequent heating of the plastics material film to a bonding temperature together with the application of a magnetic repulsion force to the pull tab urging it away from its supporting head and into forced contact with the container unit.
