Abstract: A cup dispensing package comprises an axially collapsible cylindrical sleeve for storing a stack of nested, disposable cups. The sleeve comprises at least a pair of bands at its opposite end portions, axially extending, uniformly circumferentially spaced slits between the bands that define axially extending strips provided with circumferential cut scores, and a detent on one of the bands frictionally engaging the rim of a partially extending cup to retain the latter prior to its forcible removal. The strips fold radially outwardly then downwardly about their cut scores and transverse sections thereof in response to axially applied compressive force on the sleeve, by the user, as the cups are removed, thereby presenting a fully extended frictionally retained cup for dispensing until such time the cup supply is exhausted.

Abstract: A recloseable blister card package has an opening tab which is bonded to a securing segment of the blister board. The bonded segment provides protection against tampering, and provides controlled tearing of that segment from the remainder of the board when the package is opened. After displacement the backing board has an aperture adapted for insertion of the tab to relock the blister to the board. The product may have an enlarged end and an adjacent board hinge. Interference between the blister and the enlarged end holds the product in the package under conditions which might otherwise be expected to permit it to fall out.

Abstract: An improved package for dispensing a flowable product is provided. The package has enhanced moisture resistance and is readily opened with one hand. The improvement resides in the use of an imperforate, uniaxially oriented polymeric film as a protective barrier layer over the scored outer layer of a package which comprises a scored rigid sheet member secured to a flexible sheet member forming a pocket for containment of a flowable product. The oriented film is attached over the scored rigid member to protect the contents of the package. The film ruptures when the score ruptures upon bending the scored rigid member toward the pocket to open the package.

Abstract: A multilayer film is prepared by coextruding nylon with a chemically modified polyolefin which has functional groups added to the basic polymer to provide strong adhesion to the nylon after coextrusion. The multiple layer film combines the strength and protection properties of the nylon with desired properties in the modified polyolefin. Multiple layer films may be produced by coextruding nylon layers with multiple layers of the modified polyolefin, and with additional layers of nonmodified polyolefins and other polymers. Suitable commercially available modified polyolefins for use in the multilayer film include Plexar-1 and Plexar-3 described in U.S. patent application Ser. No. 616,035, and Plexar-2 described in U.S. patent application Ser. No. 616,374, both filed in September, 1975, now abandoned, and respective continuation-in-parts thereof Ser. No. 808,080, now U.S. Pat. No. 4,087,588, and Ser. No. 808,079, now U.S. Pat. No. 4,087,587.

Abstract: A method is provided for fractionation of oil obtained by pyrolysis of lignocellulosic materials to obtain useful chemical fractions, including a phenolic fraction which is suitable as a total or partial replacement for phenol in making phenol-formaldehyde resins. The method comprises mixing the oil with a strong base such as sodium hydroxide to a pH level at which the neutral fraction of the oil is selectively soluble in a solvent such as methylene chloride or ether, and the mixture is extracted with the solvent to obtain a first extract containing the solvent and the neutral fraction, and a first raffinate containing the remaining fractions of the oil, i.e., the phenolic fraction, the organic acids fraction and an amorphous residue. The neutral fraction is recovered by distillation and the first raffinate is mixed with sulfuric acid to lower its pH to a level at which the phenolic fraction is selectively soluble in the solvent.
