摘要： A container (10) formed from a unitary paperboard blank having a substantially planar inner region (12), a sidewall region (11) and a rim region (13) formed about the periphery thereof is disclosed. The sidewall region (11) includes a generally annular region (14) flaring upwardly and outwardly from a periphery of the planar inner region (12) and a first frusto-conical region (16) adjoining the annular region (14) with the frusto-conical region (16) sloping outwardly and upwardly from the annular region (14). The rim region (13) includes an outwardly flaring arcuate annular region (18) adjoining an outer periphery of the first frusto-conical region (16), and a second frusto-conical region (24) extending substantially tangentially from the arcuate annular region (18). The second frusto-conical region (24) extends outwardly and downwardly at an angle of about 6° to about 12° and preferably about 6°-10.5° relative to the plane defined by the planar inner region (12). The rim of the container may further include an outwardly and downwardly flaring frusto-conical lip (26) adjoining an outer periphery of the second frusto-conical region (24) in order to aid in grasping of the paperboard container (10) by the consumer. Additionally, a plurality of radially extending mutually spaced pleats (50) are also formed in the rim region (13) and are internally bonded with portions of the rim region (13) during formation of the paperboard container (10) by a die press. During the fabrication of the paperboard material for forming the aforementioned container (10), the paperboard material is impregnated with a sizing adhesive equivalent to at least 6 pounds of starch per 3,000 ft² ream of paperboard material such that the tensile strength of the board is increased, and such that during the press forming of the paperboard containers between respective dies, the pleats (50) adhere to respective portions of the pleats (50) and rim, thereby maintaining the integrity of the pleats (50) during use of the container (10) by the consumer by resisting the opening of the pleats (50).

摘要： A method of foam forming of paper includes the steps of metering to a dewatering device a controlled feed of fiber dispersed in an aqueous liquid wherein the consistency of the fiber dispersed in the liquid is between about 0.5 and about 7% by weight recovering from the dewatering device a uniform continuous strand of between about 8 and 30% by weight; introducing a stream of a foamed aqueous admixture and the continuous strand of semi-moist pulp into a dispersing mixer having shearing action extending substantially throughout a zone substantially athwart the flow path of the uniform continuous strand and the foamed aqueous stream, to form a stream of dispersed fiber bearing aqueous foam; conducting the dispersed fiber bearing aqueous foam stream to the inlet of a positive displacement pump and thence through a headbox, and depositing the fibers on a moving foraminous support to form the paper.

摘要： A method of creping a fibrous web is described which comprises providing to the interface of a fibrous web and a support surface, preferably a drying surface such as provided by a Yankee dryer, a creping adhesive comprising a non-self-crosslinkable material such as a polymer or oligomer having functional groups which are crosslinkable by ionic crosslinking, and a crosslinking agent which preferably comprises metal cations having a valency of at least three, and removing the fibrous web from the support surface by creping. Also provided is a creping adhesive comprising a polymer, oligomer or mixture thereof having functional groups crosslinkable by cations, a component providing metal cations having a valency of at least three, and an aqueous solvent or diluent for the polymer or oligomer. The glass transition temperature and adhesive strength of the adhesive employed in the invention is readily controllable and the adhesive is easily removed from dryer surfaces.

摘要： An antimicrobially active, non-woven web, a wet wiper containing the web, and a method of making the web. The method includes the steps of forming an unbonded fibrous web; applying throughout the unbonded fibrous web an uncured binder and an antimicrobial agent, the antimicrobialactive agent being susbtantive to the fibers of the web and to the binder; and curing the binder material to bind the fibers together to form an antimicrobially active, non-woven web. A preferred antimicrobial agent is an organo-silicon quaternary ammonium salt, especially a 3-(trimethoxylsilyl) propyldidecylmethyl ammonium chloride or a 3-(trimethoxysilyl) propyloctadecyldimethyl ammonium chloride.
