Abstract: A tamper-indicating package that includes a blown glass container or blow molded plastic container, and a molded thermoplastic closure that is affixed to the finish portion of such container. The finish portion of the container has a radially outwardly projecting bead at the bottom portion of such finish portion. The closure has a flexible tab that originally extends outwardly and downwardly from the top of a notch in the skirt of the closure, and is foldable through the notch in the skirt of the closure to engage the underside of the bead in the finish of the container. The closure tab is attached to the closure skirt by a frangible connection, and separates from the closure skirt by the fracture of such frangible portion during the removal of the closure from the container, since the tab is prevented by its engagement with the container bead from being removed with the other elements of the closure.
Abstract: Apparatus for guiding bottles along the surface of a rotating vacuum drum which holds plastic shrink labels until an individual label is rolled about the circumference of the bottle to form an overlapped seam. The bottles are of the style that have tapering shoulder and rounded heel joined by a cylindrical side wall. The rotational orientation of the bottle and label is maintained during roll-on of the label from the drum by a primary roll-on pad and the bottle with the label thereon is passed to an generally linear, secondary roll-on pad with the sleeve label bearing bottle moved along the secondary pad by a horizontally driven, vertically oriented belt. The secondary pad at locations along its length is provided with resilient vertically extending, contoured pads which also extend outward beyond the surface of the secondary pads so as to contact the formed overlap seam of the label to press the seam against the underlying bottle.
Abstract: A labeling machine for successively applying flexible plastic labels to round containers, such labeling machine incorporating equipment to sever labels from a web of indefinite length thereof, to apply a leading edge of each of such labels to the periphery of a rotating vacuum drum, heating the leading and trailing edges of each such label while on the rotating vacuum drum by directing warm air thereagainst to heat such leading and trailing edges to a temperature at which the material therein becomes self-adhesive, and bringing the heated leading edge of the label on the vacuum drum into contact with a container rolling along a curved surface at a label transfer station to cause the label to transfer to the container and to eventually wind itself around the rolling container, thereby causing the heated leading and trailing edges of the label to adhere to the container or, in the case of a label whose length exceeds the circumference of the container, to cause the trailing edge of the label to adhere to the ov
Abstract: A vacuum drum for carrying a label held to its surface by vacuum past an adhesive applying roll to a position where the label will touch a container and the container will be rolled along the drum surface to thereby apply the label about the container. The drum is provided with a circumferential series of vacuum ports that extend through its outer surface. The vacuum to the ports is fed through passages in a bottom support plate for the drum and the passages all communicate with a stationary vacuum chamber in a collector ring which is held against the inner surface of the drum supporting plate. The collector ring vacuum chamber extends about the axis of the ring for about 180.degree. and at one end thereof serves to close off the passages to the drum in radial succession as the label is transferred to the container. Each passage, after being shut off from the vacuum, is vented.
Abstract: A labeling system where a cylindrical vacuum drum carries plastic labels at spaced intervals on its surface and a solvent applying gravure roll is held at a specific spacing from the drum and labels so that the labels will receive the solvent when they pass the rotating roll. The gap between the drum and the roll must be carefully controlled in order to be assured that the solvent is properly transferred. The gap is controlled by a fine adjustment of the platform on which the roll is mounted relative to the drum by a threaded rod moving a tapered surface of a reciprocable member in contact with a stop block mounted on the platform. The threaded rod threads through a stationary bracket and turns a shaft that threads into the member. The member is prevented from rotation so that rotation of the rod moves the member in one direction while rotation of the shaft moves the member in the opposite direction.
Abstract: A two-piece child-resistant closure having a molded plastic inner component and a molded plastic outer component, the inner component having a double ended liner retention bead that projects radially inwardly from the inside of an annular skirt portion to retain a sealing liner in a position that is adjacent to the underside of a top panel portion thereof without the need for an adhesive, the inner portion further having a helically extending thread that projects radially inwardly from the annular skirt portion, the thread having an uppermost portion with a 0.degree. helical angle that is positioned between the spaced apart ends of the double ended liner retention bead to reduce the required vertical spacing between the liner retention bead and the start of the helical thread to permit the closure to be applied to a container with a standard finish portion.
Abstract: A method and apparatus for pressing glass TV tube faceplates employing a microprocessor controlled ram and plunger operated with open loop position based speed control at relatively high rates of motion when the plunger is not in critical contact with the glass, at uniform speed as the plunger enters the glass and at closed loop pressure control after the viewing region of the cavity for the faceplate between plunger and mold has been filled out at uniform plunger pressing speed. Pressure control is employed to ramp pressure down to a pressing dwell pressure and maintain that pressure.
Abstract: A closure system for threaded containers wherein the closure is of the dispensing type and is child resistant in two aspects. Interengaging lugs on the closure skirt and container neck are so arranged that a squeezing force is required to permit the closure being unthreaded from the container. A dispensing opening in the closure top is closed by a hinged cap that meets with the upper rim of the closure in a parting line. At this parting line both the hinged cap and the top of the closure have matching protruberances that require the squeezing of the lower one in order to push up or release the cap. The plastic material of the cap and the closure are sufficiently strong that a child is unable to flex or squeeze the closure enough to open the cap or unthread the closure from the container.
Abstract: A container and closure assembly in which the container has a finish portion and the closure is secured to the finish. A circular flexible rubbery sealing liner is located at the top of the container finish and below the cap, and a circular barrier liner that is printable if desired, is provided between the closure top and the flexible liner to reduce the passage of permanents such as O.sub.2 and CO.sub.2 therethrough.

Abstract: There is disclosed a gas discharge panel, especially of the type described in U.S. Pat. No. 3,499,167 or 3,559,190, operated with an ionizable gaseous medium of neon and at least one minority rare gas component selected from argon, krypton, and xenon. In one embodiment, there is used a gaseous medium of about 99.5 to 99.99 percent atoms of neon and 0.5 to 0.01 percent atoms or at least one minority gas component.
Abstract: A solid deodorant dispensing package that includes a container with a dispensing opening, a solid deodorant with a portion that extends through the dispensing opening of the container upon the squeezing of the container, and a closure that is formed integrally with the container for selectively opening and closing the dispensing opening. The container is generally wedge-shaped with first and second major sides diverging away from one another as they extend from a juncture therebetween to the dispensing opening and with pleated ends which extend between the first and second major sides which, because of their pleated configuration, permit the included angle between the first and second major sides to be reduced by squeezing the first and second major sides, an action which advances the solid deodorant through the dispensing opening.
Abstract: A molded plastic closure for a beverage container, the closure having a shell with a top panel and a depending skirt, the shell being molded in one piece from a hard thermoplastic material. The closure is provided with an annular flange which extends from the underside of the top panel and which forms an annular space with the inside of the skirt. A liner is formed in situ within the closure by compression molding from a compression moldable soft, rubbery thermoplastic material, the underside of the top panel and the inside of the annular flange serving as molding surfaces. The annular flange is supported against lateral loads by a series of ribs which extend between the annular flange and the depending skirt. The liner is interlocked with the annular flange by interengaging ribs and recesses. Both a top seal only closure for non-pressurized beverages and a top and side seal closure for pressurized beverages are disclosed.
Abstract: A tamper indicating package comprising a one-piece molded closure of plastic which threads onto a container such that when the closure is unthreaded, a tamper-indicating ring becomes separated from the lower end of the closure skirt. The indicating ring or band is joined to the closure along a weakened frangible line and a flexible stop ring is formed within the band and extends inwardly and upwardly when the closure is applied to a container finish. The container finish has a first radial bead, a second radial bead spaced axially below the first bead, and an intermediate tapered or concave surface between the first radial bead and second radial bead. A further surface extends from the second bead axially downwardly and radially inwardly and the flexible end of the stop ring rests on this surface between the two beads, when the closure is applied.
Abstract: A solid deodorant dispensing package that includes a container, a solid deodorant holding cup which is moveable in a cavity in the container between a dispensing position in which a portion of the solid deodorant extends through an opening in the container and a storage position in which such portion of the solid deodorant is entirely contained within the container, and a closure which is hingedly attached to the holding cup and which is formed integrally therewith. In one embodiment of the invention, the closure is a generally L-shaped member which is folded back approximately 180.degree. through a partial depth opening in one of the sides of the container, to present one of the legs of such L-shaped closure member at a position where it can be readily grasped to permit the advance and the retraction of the holding cup within the cavity of the container.
Abstract: A vacuum indicating closure for a container for the packaging of a vacuum-packed product, the closure being of two-piece construction and having a metal lid portion which is retained in sealing engagement with the rim of a container by a plastic ring portion. The metal lid portion has a vacuum indicating button centered therein, which vacuum indicating button can flex downwardly from its normal position into the headspace of a container under the influence a sub-atmospheric or negative pressure in the headspace. The ring portion of the closure has a radially inwardly projecting annular flange at the top thereof to urge a peripheral portion of the lid portion of the closure against the rim of the container, the ring portion of the container further having a radially inwardly projecting annular bead to lock the lid portion of the closure against the underside of the annular flange of the ring portion so that the lid portion and the ring portion can be conveniently handled in unison.
Abstract: A closure having interrupted threads, wherein the interruptions between thread segments are vertically aligned with and are at least as long as thread segments in the overlapping portions of the turns of the thread. This permits manufacture of the closure by stripping of the closure threads from a mold to obtain a higher rate of production while minimizing the pulled-thread defects previously encountered with this production method. In addition, the invention is also utilized to provide an improved closure and package in which two hand operations by the user are required to remove the closure from a neck, thereby permitting internal pressure to be released through interrupted threads before the closure and neck threads are completely disengaged.
