Abstract: A closure configuration for the top of a carton wherein the underneath flaps of the closure are scored to facilitate sealing.

Abstract: A decoration is transferred to a cylindrical body by employing a surface so configured as to maintain continuous contact with that body throughout the time of transfer; the body is supported for rotation during and as an incident to transfer but it may be positively driven at a greater speed, particularly in the instance where the decoration is a thin film label, which needs to be tensioned.

Abstract: A round tray and a blank for making the tray. The tray has a bottom panel, a plurality of intermediate panels symetrically disposed about the center of the bottom panel, and a plurality of upstanding panels to form the sides of the tray. The upstanding panels may be tilted slightly outward in a conical shape to cause the diameter of the top of the tray to be slightly larger than the diameter of the bottom of the tray. Alternate ones of the upstanding panels are positioned on the inside of the tray, and their adjacent upstanding panels have circumferentially extending glue flaps which overlap the inner panels. The total number of upstanding panels and the total number of intermediate panels are equal, with each upstanding panel being foldable relative to an intermediate panel immediately below it about a first set of fold or score lines. The intermediate panels, in turn, are folded upward from the horizontal about a second set of fold or score lines.

Abstract: A reclosable hinged blister card package wherein the clear plastic blister is adhered to a paperboard card which is suitably cut-scored along the adhered areas to allow defined ply separation of the card for opening the blister. The blister is hinged at its bottom end to the card and has an opening tab overlaying a cut-out opening in the card. Locking ears on the opening tab are adapted to be pushed through the cut-out opening to lock the blister in reclosed position.

Abstract: A door has a flexible channel along its free edge which flexes upon striking an obstruction and brings together two conductive ribbons within the channel. The ribbons are part of an active circuit which includes a relay coil. Temporary contact of the two conductive ribbons resulting from contact with the obstruction de-energizes the relay coil, fully opening the door. Since door opening results from de-energizing a coil, a power or circuit failure will also cause the door to open.

Abstract: This invention is an improved electronic detection system for leaks in articles such as can tops and the like comprising a special ultrasonic microphone-amplification system for listening for leaks in articles, a signal averaging network to receive the signal produced by the amplifier and to improve the signal to noise ratio, an enable circuit which is synchronized with the pressurization of the article to be leak tested and which triggers the signal averaging network and a comparator to receive the averaged signal from the signal averager. The comparator produces a logic pulse for rejecting leaky articles when the averaged signal produced by the signal averaging network is above a predetermined level.

Abstract: A premoistened wiper having high initial wet strength in a wetting liquid, and lower wet strength when immersed in substantially neutral water to allow for flushability. The wiper includes a nonwoven web of fibrous material which is bonded together by a polymeric adhesive binder, with the bonded web being moistened until the time of use by a wetting liquid having an acid pH level which is safe for external use on the human body. The binder is composed of a material which is highly adhesive in an acid pH liquid to bind the fibers of the web together, and which is further resistant to weakening over the relatively long periods of shelf life of the wiper. However, the binder loses its binding strength in substantially neutral or alkaline flush water to allow for flushability. The bonded wiper is maintained with wetting liquid thereon within a moisture sealed container until the time of use, and readily loses strength and disintegrates when disposed of in the substantially neutral water of a sewer system.

Abstract: A shield for an assembly includes a member of generally corrugated construction, which is uniquely configured to substantially prevent the passage of liquid contaminants impinging thereon. The invention is especially concerned with the provision of an acoustical assembly employing such a shield.

Abstract: Photopolymerizable compositions and processes for photopolymerizing such compositions are provided, said process comprising admixing with said epoxides, photosensitive organohalogen compounds and thereafter applying energy to the resulting mixture. The organohalogens decompose to liberate an active catalyst which then serves to initiate polymerization of the epoxide material.

Abstract: Printed and varnished surfaces are provided by depositing a base film or printing on a substrate and depositing, wet-on-wet, a protective varnish or top coat after which the multilayers are exposed to an energy source, preferably to electromagnetic radiation, to simultaneously cure the varnish and ink on said substrate.

Abstract: A new score line configuration having easy opening characteristics for opening an ice cream carton and the like, has the characteristic of avoiding premature separation particularly during set up of the carton.

Abstract: Tamperproof reclosable cartons are provided from a single paperboard blank which includes a receptacle portion and a cover portion which telescopes over the upper edges of the receptacle portion. The cover portion includes a front cover panel and the front wall panel of the receptacle portion includes an integral bridging panel comprising a central sealing tab and flanking tab portions. The front cover panel comprises at least one central tab area outlined by readily severable lines of weakness designed to be punched out upon opening the carton providing a readily visible indication that the carton has been opened.

Abstract: Continuous strip cast aluminum alloy of relatively high manganese content which is size-reduced suitably thin for conversion into cans and like fabrications is given an anti-galling character for such severe metal working conditions as drawing and ironing in can making and in equivalently difficult operations by heat treatment of the strip product prior to its final cold reduction pass at temperatures in the 900.degree. F. + range for at least about 4 hours.

Abstract: An enclosure, for example, a safety enclosure around noisy or potentially dangerous machinery, includes a door which, when opened, stops the operation of the machine to prevent injury to personnel who may examine or maintain the machine. A pneumatic safety system for the door includes, in series, a source of compressed air, an air regulator valve, a series of disconnectable air connectors and a transducer, such as an air pressure limit switch, which converts a decrease in air pressure into a control signal to stop the operation of the machine. One air connector member is mounted on the door and another on the door frame, so that they are automatically disconnected when the door is opened, thereby opening the pneumatic line and causing the air pressure to decrease. The connector members each have a flat face which meet in a flush relationship, one connector member having a round orifice and the other connector member having a multi-slotted orifice which leads to an internal air cavity.

Abstract: Highly pigmented liquid epoxide coating compositions containing one or more liquid epoxides, up to 60% by weight of pigment, one or more carboxylic acid anhydrides and specified diazonium salts of Lewis acids are converted to solid materials with substantially no weight loss following a relatively short exposure to ultraviolet radiation. The heretofore unattainable objective of a light-curable, substantially solventless coating composition containing sufficient pigment to obtain acceptable levels of hiding power is achieved by the presence of the carboxylic acid anhydride.

Abstract: A flexible packaging sheet material bearing a tacky wax composition coating and a non-blocking overcoating in the form of a continuous film of an ethylene-vinyl acetate copolymer which incorporates between 10 and 35 percent by weight of solid low to medium density polyethylene particles of a size smaller than about 50 microns.

Abstract: Photoinitiator-free inks and a method of producing printed and varnished surfaces are provided by depositing a base film or printing on a substrate and depositing, wet-on-wet, a protective varnish or top coat after which the multilayers are exposed to an energy source, preferably to electromagnetic radiation, to simultaneously cure the varnish and ink on said substrate.

Abstract: A folding paperboard carton including an interior divider is formed from a single-piece blank. The divider is attached to a flap or wall panel of the carton blank, and after the carton is glued in a folded mode, unfolding the carton to its set up mode releases the divider from its attachment to the flap or wall panel to form a divided carton.

Abstract: A carton particularly adapted for ice cream including a front wall, bottom wall, rear wall, top cover panel, front cover panel, corner glue tabs, cover end skirt panels, rearward and front inner end wall panels, and a pair of end walls, wherein, said end walls have a weakness line separating their outer margins from the lower panels thereof and said cover end skirt panels are glued to said outer margins to break said outer margins away from the lower panels of said end walls when the erected box is opened.
