Abstract: A reclosable cup lid thermoformed from a polymeric material includes a domed member and a closure panel. The thermoformed domed member is provided with a sidewall and a top wall, the top wall having upper and lower surfaces and a drinking aperture at a periphery of the top wall. The top wall further defines a pair of engagement tracks depending from the lower surface of the top wall and also defines a post aperture disposed inwardly with respect to the drinking aperture. The closure panel has opposed engagement edges, an upper surface provided with a post projecting upwardly therefrom, and a drinking aperture sealing area. As assembled, the domed member and closure panel are configured such that the opposed engagement edges of the closure panel are slidingly mounted in the engagement tracks for generally radial displacement.

Abstract: The inventive drinking vessels are prepared by stretch blow-molding a preform and exhibit increased Rigidity as well as elevated, preferably relatively uniform crystallinity. A preferred method of making blow-molded stackable drinking vessels includes expanding a preform both axially and radially to make an intermediate article with a neck, a transition portion and a tumbler portion. The transition portion and neck are severed from the tumbler which is then fortified around its upper aperture which is larger than its base.

Abstract: A tear-back drink-through lid for a drinking cup sealingly engages the drinking cup at an annular mounting portion with a downwardly extending annular skirt. The tear-back section extends from the inner skirt to a hinge and has an outwardly extending raised protrusion. When the tear-back section is torn away from the lid and pivoted about the hinge, the raised protrusion is frictionally engaged by the end walls of the recess and retained within the recess. The recess further includes a straw slot formed therein defined by two sloping converging sidewalls extending from the upper surface the lid at different angles to form a frangible juncture at the deepest portion of the recess.

Abstract: A device for making containers, comprising a paper feeding system configured to feed side blanks, a sleeve-forming unit receiving the slide blanks and forming them into sleeves, a bottom forming unit configured to form bottoms, an indexed container-forming turret for receiving the sleeves and the bottoms and adhering a bottom to each sleeve, and a continuously running mechanism to remove sleeves from the sleeve-forming unit and transfer them to the container-forming turret.

Abstract: A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas.

Abstract: A moist wipe having a web of fibers stabilized as with a suitable binder, and the stabilized, dry web having an anionic surface charge not greater than about 1.2 meq/Kg. A cationic functional agent in an aqueous imbuement is added to the web which is partially adsorbed by the web and a portion of the agent remaining free. Because the anionic surface charge on the substrate is relatively low, there remains in the free aqueous medium a sufficient quantity of the functional agent deliverable to the surface to achieve the desired efficacy. The resulting web will adsorb a limited amount of the cationic functional agent in the aqueous imbuement, and thereby an adequate amount of the agent remains in the solution free of the web for deliverance to the surface, thereby obviating high loadings of the imbuement and the active functional agent.

Abstract: This invention relates generally to lidded disposable pressed paperboard containers and more particularly to a disposable lid with an engagement profile particularly useful for paperboard containers comprising evert outer portions. The lid of the present invention provides a good fit for paperboard container bases having evert outer portions while still allowing the lid to be removed from the base without the need for excessive force. The lid profile is relatively insensitive to size variations of paperboard container bases having evert outer portions and allows for flexing of paperboard during application so as to provide an unexpectedly good seal so as to provide lidded, disposable paperboard containers.

Abstract: A method of processing papermaking fiber includes characterizing the initial color of the pulp and the color of the pulp after treatment with a phloroglucinol stain. The color response of the pulp to the stain has been found to be a better indicator of processing needs for secondary pulps in particular and in any event is selective for untreated groundwood as opposed to conventional groundwood identification methods. The color difference is used to target a suitable product for the pulp, to aid in bleaching/deinking strategy or to enable optimization of fiber blending for particular products. In a preferred embodiment the process includes determining changes in CIE L*, a*, b* and brightness values before and after staining of the pulp.

Abstract: An improved pressware die set includes mechanical ejectors for removing formed product from the punch. A preferred embodiment includes rocker-style ejectors free from edges or other asperities which may tend to snag and mar the product during the production process. Most preferably, the outward surfaces of the rocker members extend beyond the perimeter of a paperboard blank positioned for forming so the paperboard blank does not encounter an obstruent outward edge during forming.

Abstract: An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.

Abstract: A multi-panel dispenser napkin folded on a napkin folder and produced from a paper web and having a plurality of equally sized panels. The width-to-length ratio of the fold configuration is selected from the range of about 0.4 to about 0.7. The fold configuration has at least one transverse fold formed on the folder along the transverse dimension of the paper web and at least two longitudinal folds formed on the napkin folder along the longitudinal dimension of the paper web. None of the equally sized panels has an off-fold panel. The fold configuration is characterized by generally uniform thickness.

Abstract: A deep dish disposable container is preferably prepared from a radially scored paperboard blank and has a substantially planar bottom portion, an upwardly projecting sidewall portion and an outwardly extending flange portion. The flange and sidewall are provided with a plurality of circumferentially spaced, radially extending densified regions formed from a plurality of paperboard layers reformed into substantially integrated fibrous structures generally inseparable into their constituent layers having a thickness generally equal to adjacent areas of the sidewall and flange portions to provide uniformity and strength. The deep dish container generally has a height to diameter ratio of from about 0.1 to about 0.16; whereas the radially scored paperboard blank has from about 50 to about 100 radial scores. The product is dimensioned and configured such that there is from about 0.015 to about 0.05 inches of excess paperboard per score about the flange portion in order to provide rigidity to the product.

Abstract: A method for making paper to enhance its wet strength includes adding separately to a cellulosic paper pulp furnish the following additives to form a treated pulp: a cationic wet strength resin whose cationic sites bond to anionic sites of cellulose fibers contained in the paper pulp furnish, and a hydrophobically modified anionic polyelectrolyte whose anionic sites bond with cationic sites of the cationic wet strength resin.
