Abstract: A sealing element that visually indicates when a sealing element has been opened or corrupted without destruction of the seal. Ultraviolet light passes through a scattering layer and is absorbed by a fluorescing layer, the fluorescing layer reemitting the light in the visual spectrum and thereby allowing a user to inspect the integrity of the sealing element without otherwise destroying the seal.

Abstract: A blank of material to be folded into a product display container is disclosed. The blank is substantially rectangular in shape and has a first edge, a second edge opposite of the first edge, a third edge disposed adjacent to the first edge and the second edge and a fourth edge disposed opposite the third edge. The blank comprises a tab disposed adjacent to the fourth edge; a plurality of perpendicular folds, wherein each perpendicular fold extends across the width of the blank and is disposed substantially perpendicular to the first edge and the second edge; and a plurality of angular folds, wherein each angular fold extends across the width of the blank and is disposed at a non-perpendicular angle with respect to the first edge and the second edge. The blank is utilized to make a tornado shaped product display.

Abstract: According to the present invention, a laminar wrapping paper is provided comprising first and second paper layers or laminae. Each lamina has an inside surface coated with a barrier coating. The layers are laminated by heat lamination, wherein the barrier coatings are melted together, or by providing an adhesive between the coated inside surfaces. The lamination may be accomplished in a selective or discontinuous manner in order to form air pockets within the laminar structure to increase the insulation characteristics of the wrapping paper. A plasticizer is applied to the outside surface of the first lamina. Graphic designs or lettering may be printed on the outside surface to identify the wrapped product or for purposes of decoration. The present invention is also directed at a process and apparatus for manufacturing the laminar wrapping paper described herein. First and second webs of paper are unrolled and passed through coating apparatus to coat one side of each web with a barrier coating.

Abstract: A box having a cover with a plurality of windows and at least a majority of the windows being elongated and oriented in generally spaced relationship with respect to each other. Each window is defined at least in part by a pair of spaced window defining sides. A first or leading series of such window defining sides is disposed in non-parallel relationship with each of a second or trailing series of window defining sides. This serves to facilitate manufacture of boxes from blanks that are readily movable over each other without undesirable edge-to-edge continuous contact which inhibits relative sliding movement during manufacture. The non-parallel window defining sides may be inwardly concave or have each window defined in part by a pair of straight window defining sides which diverge. An associated method for establishing container blanks of this type is disclosed.

Abstract: A bakery food package for releasably and securely holding cakes, pies and other baked goods. The package includes a base for supporting the bakery goods and a cover secured to the base. The base has a plurality of circumferentially spaced second locking elements removably engaged with a plurality of first locking elements which are formed on the cover. The cover has a top wall, depending sidewalls and a generally outwardly projecting lower flange. In one preferred embodiment of the package, the second locking elements may be generally upwardly and inwardly rotated along a pivotal axis in order to permit portions of the first locking elements to pass therethrough and engage the same. Portions of the outwardly projecting lower skirt of the cover member extend downwardly to resist free relative sliding and rotating movement between the cover member and base. The base may be corrugated board and may be provided with an upper foil layer.

Abstract: A container with an externally threaded neck portion is adapted to be closed with a closure having an internally threaded sidewall engaging the threads of the neck portion. The threads of the neck portion have at least a lower stop disposed at the inner end of the thread. The threads on the container neck are divided; the threads have a maximum pitch of 8 degrees. The stop on the thread on the neck portion and a stop on one part of the divided thread on the closure insure that the closure is stopped at a predetermined position relative to the container after full-threaded rotation of the closure onto the threaded neck portion has been carried out. The threads on the closure are divided by symmetrically disposed gaps. An anti-rotational stop is provided forcibly to retain the closure in its final, fully applied position while permitting the closure to be removed by the application of an initial relatively high torque.

Abstract: A manually operated actuator for a pump employs a vertical hollow chamber. A piston is vertically slidable in the chamber between a bottom position at which no pumping action can take place and a top position at which pumping action can occur. The piston and the chamber are contained in a housing. A trigger is pivotally secured in the housing and is connected to the piston. The trigger has a first position at which the piston is held in the bottom position and has a second position at which the piston is held in the top position. The trigger is normally in the first position and is manually movable into the second position. A spring device is disposed in the housing, being secured to the trigger and spaced from the chamber and piston. The device biases the trigger into the first position whenever there is no manual pressure on the trigger.

Abstract: A container with a threaded neck portion is adapted to be closed with a closure engaging the threads of the neck portion. The threads of the neck portion have at least two stops disposed at opposite ends of the threads. The threads may be continuous or interrupted but have a maximum pitch of 8 degrees. The two stops of the threads on the neck portion insure that the closure is stopped at a predetermined position relative to the container after full-threaded rotation of the closure onto the threaded neck portion has been carried out.

Abstract: A method for threading a closure having cylindrical walls which includes securing the closure in a stationary nest, inserting a threading tool having indentions on the outside thereof into the interior of the closure, moving the closure into a ring having projecting threads on the inside thereof around the outside walls of said closure, moving the threading tool into contact with the interior portion of the closure upon which threads are to be formed, and moving the threading tool around the interior portion of the stationary closure in an orbital path to form threads in the closure without rotating the threading tool about the threading tool axis.

Abstract: Glassware forming apparatus includes a parison mold, a blow mold, a pair of neck rings for supporting glassware blanks, first and second invert arms for supporting the neck rings and first and second arbors for supporting the first and second invert arms, respectively. The invert arms support their respective neck rings for movement in a common vertical plane. The axes of the arbors extend generally parallel to one another and generally perpendicular to the common plane. The molds have parallel vertical axes lying in said common vertical plane. Apparatus is provided for shifting the arbors such that their axes move toward and away from one another during an operating cycle. Apparatus is provided for pivoting the arbors about their axes to move the neck rings in invert and revert arcs between the parison mold and the blow mold.

Abstract: Glassware forming apparatus includes a first arm for supporting a first neck ring and a second arm for supporting a first blow head. The first and second arms are supported from a vertical column for projection along its axis and for independent pivotal movement about the axis. The apparatus also includes a parison mold and two blow molds. Each of the blow molds is divided into two portions, the portions of each mold being joined at a hinge. The axis of each hinge extends generally parallel to the column axis. Apparatus is provided for opening and closing the molds, and for pivoting and projecting the first and second arms to convey glassware blanks supported by the neck ring alternately to the two blow molds from the parison mold, and to move the blow head between the two blow molds to blow the glassware blanks into articles of glassware.
