Abstract: A folder for containing a strip of blister package units for pharmaceutical capsules includes a generally flattened sleeve of paperboard having side wall panels and a planar panel folded inwardly from an edge of the sleeve material. The panel is generally coplanar with one side wall panel of the sleeve, and includes a window, wherein a strip of severable blister package units may be inserted within the sleeve so that the blister portion of at least one of the units projects through the window, whereby the strip is retained within the sleeve.

Abstract: A process is provided for forming a plurality of objects simultaneously from a plurality of superimposed sheets of deformable and fusible material comprising the steps of heating said plurality of superimposed sheets until said material in said sheets reaches a temperature sufficient to allow plastic deformation while maintaining time, temperature and pressure conditions at the contiguous faces thereof below those causing fusion of said material and forming said plurality of superimposed sheets simultaneously.

Abstract: Multilayered sheet material, a method for producing said material and a package comprising said material are provided. The multilayered material and package produced therefrom have apertures sealed with an extrudable hot melt material which conveys moisture barrier properties and is adapted to soften and permit venting of vapor generated in the package prior to distortion of the package. The packages are adapted particularly for use as containers or as components thereof when used in heating or cooking of foods in microwave ovens.

Abstract: Improved air laid papermaking is disclosed in which the fine particles which pass through the forming wire are, after collection by a baghouse separator, delivered back to the papermaking machine for incorporation in the web being formed by the machine. A plurality of individual separator units within the baghouse are sequentially discharged so that a substantially constant feedback of fines to the papermaking machine is obtained. The fines are fed back to a selected one of the distributors of the papermaking machine to be distributed to the surface of the web being formed at a position downstream of the position at which fibers are initially laid on the wire, thereby trapping the fines on the surface of the previously laid mat of fibers such that very little of the fines pass through the forming wire at this position.

Abstract: A distributor for receiving an air suspension of fibers and uniformly spreading them over a moving forming wire. Upper and lower parallel rotors in the distributor have parallel axes and rotor bars. The lower rotor is rotatable to distribute fibers through screen openings in a lower curved housing wall over the wire. The upper rotor bars pass in close proximity to a breaker bar extending into the distributor, and against which breaker bar clumps of fibers too large to pass through the screen openings are impacted and broken down into individual fibers capable of passing through the screen openings.

Abstract: A carton incorporates a new product release film into its tear strip, and greatly improves performance of the tear strip. The release film is uniaxially oriented, and is aligned with the tear strip, thus controlling tear strip function. Weakening cuts in the paperboard of the tear strip can now be significantly modified for manufacturing efficiencies, while the composite tear strip has enhanced performance and reliability.

Abstract: A method and system for applying a foamed binding agent to a fibrous web is disclosed. The invention is characterized by the use of an extruder having an upper lip extending 1/16 to 1/4 inch beyond the lower lip, and by the drawing of a vacuum beneath the applied foam, said characteristics being critical to the formation of a uniform foam layer atop the web. A second, more substantial vacuum is then applied beneath the web to essentially completely draw the binding agent into the web thereby providing substantial inter-fiber bonding.

Abstract: A carton has side and bottom walls of generally rectangular configuration, a pair of dust flaps hinged for closure on opposed side walls, and a pair of closure flaps hinged on opposed walls perpendicular to the first, for closure over the dust flaps. The dust flaps are constructed and arranged to be hinged inwardly of the carton and include cut-out sections that receive neck portions of a dispensing bottle and a rotationally locked dispensing nozzle thereon to hold the nozzle in place and to hold the bottle stationary as against movement about its base which is itself engaged, and held from shifting, by the carton side walls.

Abstract: Apparatus for forming a deep drawn paperboard container coated with a layer of grease and water impermeable polymeric material. A paperboard blank is disposed between and acted upon by a heated mandrel and a heated mold to form a container. The surface of the blank engageable by the mandrel bears the polymeric coating, and means are operative relatively to move the mandrel and mold toward one another, to engage, the blank, and, just prior to fully engaging the blank to set the same, to introduce a film of air between the heated mandrel and the polymer coated surface to ensure against sticking of the coating to the mandrel.

Abstract: In a multiple compartment carton, one compartment has a line of weakness for opening the compartment. Protective means overlies the line of weakness, to prevent inadvertent breakage of the line of weakness.

Abstract: An improved bacon package is disclosed. The stiffening packaging element, commonly known as a bacon board, has full width top and bottom panels which support the bacon from the bottom and cover it over the entire top. Cover flaps on the ends of the top panel are defined by lines of weak bending resistance, and function to cover the ends of the array of bacon when the packaging element and bacon are enclosed in plastic films in a vacuum packaging operation.

Abstract: New bacon packaging is disclosed. The stiffening packaging element, commonly known as a bacon board, has full width top and bottom panels which support the bacon from the bottom and cover it on the top. Special cover flaps on the ends of the top panel are defined by transverse lines of weak bending resistance. The cover flaps, which function to cover the ends of the array of bacon, have segmental arcuate lines of weak bending resistance extending from the free edge of the cover flaps to the corresponding transverse line, and back to the free edge.
