Abstract: An apparatus for spraying the surfaces of glass containers which are being moved in longitudinally spaced transverse rows by a conveyor wherein a rodless air cylinder is mounted transversely of the conveyor and the spraying apparatus is connected to the piston of the rodless cylinder so that the spraying apparatus is moved transversely of the rows of containers. The rodless cylinder is supported for pivotal movement about a vertical axis so that the axis of the cylinder may be moved to a position other than a right angle to the longitudinal axis of movement of the conveyor. The offset of the angle from a right angle and the speed of traverse of the piston is coordinated with the conveyor speed so that any time during the travel, the spray apparatus is spraying between the rows being sprayed.

Abstract: Appratus for automatically removing stuck and down ware from an automatic glassware forming machine conveyor produces a first signal for each item of normal ware, stuck ware and down ware which is conveyed past an inspection location. Each of the first signals has a duration corresponding to the time required for passage of the corresponding item past the inspection location. In order to prevent the generation of spurious first signals, two spaced radiant energy beams are sensed which are directed transversely across the transport path of the wares and which are in coplanar alignment perpendicular to the transport path of the wares. A first one of the beams is aligned with the bases of upright wares and the other of the beams is aligned above the first beam. The first signal is produced if either of the beams is interrupted.

Abstract: A method for sealing a rim-like opening in a glass container is described. The surface of the opening is treated with tin and/or titanium oxide precursors and with or without one or more of the groups consisting of fluorides, sulfur oxides and sulfur oxide precursors and then overcoated with a chromium III organic metallic complex. A membrane comprising a thermoplastic film is pressed onto the coated opening surface and heated to cause glass-plastic adhesion, forming a closure. The coating steps may be applied to glass containers immediately after forming and annealing as appropriate, or may be applied to glass containers taken from storage.

Abstract: Apparatus for automatically removing stuck and down ware from an automatic glassware ware forming machine conveyor produces a first signal for each item of normal ware, stuck ware and down ware which is conveyed past an inspection location. Each of the first signals has a duration corresponding to the time required for passage of the corresponding item past the inspection location. The apparatus also produces a second signal simultaneously with the production of each of the first signals, the second signals having a predetermined duration corresponding to the time required for a normal upright and spaced item of ware to be conveyed past the inspection location. The generation of a reject signal during the duration of each of the second signals is inhibited and a reject signal is generated if a first signal is present after the termination of the corresponding second signal, which actuates a signal responsive automatic ware removal mechanism.

Abstract: A method for preparing a glass container, and for sealing a glass mouth of a container and the seal are described. The sealing surface, or finish, of the container is subjected to a hot end treatment after forming and before annealing to enhance adhesion between the container finish and a thermoplastic membrane seal. The container is next annealed and after annealing is subjected to a cold end treatment in which the exterior container surface is coated with a material which enhances the lubricity and increases the abrasion and scratch resistance of the container. The container finish only is then subjected to a brief heat treatment sufficient to remove any lubricity enhancing material from the finish. A membrane comprising a thermoplastic film is pressed onto the container finish and heated causing glass-plastic adhesion and forming a closure.

Abstract: A glass container having an upper rim for dispensing the contents thereof and a sealing membrane adapted to be applied to said rim to seal the contents of the container. The sealing surface of the container is prepared by treatment with fluorine and a metal oxide, or a sulfur oxide and a metal oxide, or with fluorine alone or a sulfur oxide alone, at an elevated temperature. To form the closure a membrane comprising a thermoplastic film is applied over the sealing surface and heated to result in a glass/plastic adhesion. The membrane may be a thermoplastic polymer/aluminum foil laminate.

Abstract: A method for preparing a glass container, and for sealing a glass mouth of a container and the seal is described. The sealing surface of the container is prepared by treatment with fluorine and a metal oxide, or a sulfur oxide and a metal oxide, or fluorine alone or a sulfur oxide alone, at an elevated temperature, in the case of fluorine employing a fluoride compound which decomposes at the temperature and, in the case of a metal oxide employing a metal oxide precursor. To form the closure, a membrane comprising a thermoplastic film is pressed over the sealing surface and heated to result in glass-plastic adhesion. The membrane may be a thermoplastic polymer/aluminum foil laminate.
