Abstract: A closure for a container comprising a body of synthetic plastic material including a top wall and a peripheral skirt, removably engaging a container. An annular channel is provided on the inner surface of the top wall at the area of juncture of the top wall and the skirt. The channel comprises integral side wall portions and at least one of said side walls comprises spaced generally vertically extending ribs. A sealing gasket is cast in situ in the channel and interlocks with the spaced ribs.

Abstract: A collapsible, bulk shipping container with a take-out front panel that is made up of an inverted tray-type rectangular bottom, a collapsible three-sided body, one end of which is telescopically received in the tray-type bottom, and a removable take-out front panel that forms a tubular body with the three-sided body. The collapsible three-sided body is collapsible from a fully open position, in which it is U-shaped in configuration and in which it and the removable take-out panel form a tubular body which fills the tray-type bottom, into a collapsed condition in which it lies against one side of the tray-type bottom, one side of the collapsible three-sided body, the middle side, being secured to one side of the tray-type bottom. When the collapsible three-sided body has been collapsed, it can be folded over to lie against the tray-type bottom in a compact configuration for ease of the shipment or storage of at least these components of the bulk shipping container.

Abstract: Platinum corrosion reducing amounts of a premelted oxide mixture that is PbO and B.sub.2 O.sub.3, or PbO and SiO.sub.2, or PbO, SiO.sub.2 and B.sub.2 O.sub.3 are added to raw batch ingredients for a lead-containing solder glass. All or part of the Pb.sub.3 O.sub.4 or PbO normally used in the raw batch is replaced for advantages including reducing the amount of platinum corrosion in a platinum melter used to melt the raw batch to provide the glass.

Abstract: A label magazine comprising a tray for supporting a stack of labels and having a device at one end for yieldingly urging the labels toward the other end of the tray and a plurality of circumferentially spaced spring fingers positioned at the other end of the tray about the labels, each finger including an axially extending portion and an inwardly extending portion engaging the outermost label of the stack. Each finger is mounted so that it can be adjusted to move the finger inwardly of the label and accomodate variations in the size of the labels.

Abstract: A child-resistant package that includes a wide mouth 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 flange at the bottom portion of such finish portion, and this flange has a notch in its outer periphery. The closure has a flexible projection that extends outwardly and downwardly from the skirt of the closure, and a portion of this projection engages the notch in the flange of the finish to prevent the turning of the closure on the finish. The projection of the closure can be manipulated by hand to remove the portion of the projection that engages the notch in the container finish to disengage the closure projection from the container finish notch, to permit the removal of the closure from the container.

Abstract: In the application of a volatile solvent to a plastic, roll-on label for a bottle, a large diameter solvent applicating roll is formed with small diameter gravure rolls that extend from the surface of the solvent applicating roll. The small diameter rolls are circumferentially spaced from each other a distance that is equal to the spacing between the leading edge and trailing edge of a plastic label carried on the surface of a transfer drum. The small gravure rolls are relatively rotatable with respect to the large roll and are supplied with solvent from behind within the large roll.

Abstract: Disclosed are pH responsive glass compositions which contain specified proportions of LiO.sub.2, SiO.sub.2, La.sub.2 O.sub.3, and Ta.sub.2 O.sub.5. In some embodiments, the glasses also contain a small proportion of Cs.sub.2 O. The glasses have very low electrical resistivity, are stable against devitrification, and are readily melted and formed into shapes which are suitable for glass electrodes.
