Patent number: 5597253Abstract: A refill cartridge for a stick product dispenser, for stick products including adhesive sticks, lipsticks, release agent sticks, shaving soap sticks, coloring sticks, and so forth, is provided by molding the stick product material to have a shape substantially the same as the internal shape of the associated dispenser casing or holder, and to fill the free internal volume of the holder. When the stick product originally within the dispenser is used, the refill cartridge is partially inserted into an open end of the empty dispenser holder, and the cartridge is either pushed or drawn into the dispenser, for refilling the same with the desired stick product, and permitting nonconsumable portions of the stick product dispenser to be repeatedly reused via such refilling.Type: GrantFiled: March 27, 1995Date of Patent: January 28, 1997Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Tilwin Lepsius, Gerhard Gierenz, Klaus Tranelis, Gerd-Ruediger Reinfelder, Joachim Franken, Hans Halm

Patent number: 5433775Abstract: The invention relates to a dimensionally stable, soft-rubbing adhesive stick consisting of a water-based preparation of starch derivatives and a soap gel as the shaping gel-forming component and, optionally, other auxiliaries. To obtain an adhesive stick which is largely based on natural raw materials and which may therefore be regarded as safe from ecological and toxicological standpoints, the invention is characterized in that viscosity-reduced starch ethers are present as the starch derivatives.Type: GrantFiled: February 28, 1994Date of Patent: July 18, 1995Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Karl-Josef Gardenier, Gerhard Gierenz, Wolfgang Klauck, Bernd Peters, Horst Donothek, Norbert Doering

Patent number: 5371131Abstract: The invention addressed the problem of improving the adhesive strength of a dimensionally stable, soft-rubbing adhesive stick consisting of an aqueous preparation of a synthetic polymer and a soap gel as gel-forming component and, optionally, other auxiliaries. This problem was solved by the use of an at least substantially solvent-free aqueous polyurethane dispersion as the aqueous preparation of a synthetic polymer.Type: GrantFiled: February 19, 1992Date of Patent: December 6, 1994Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Gerhard Gierenz, Wolfgang Klauck, Rainer Hoefer, Roland Gruetzmacher

Patent number: 4992500Abstract: Aqueous dispersions of thermoplastic polyamides based on dimeric fatty acids having melting points of at least 120.degree. C. or of mixtures of these thermoplastic polyamides, in which at least 20% of the polyamide has a melting point of at least 120.degree. C., and which contain salts of rosin derivatives having acid values of more than 120 as emulsifiers, show excellent properties as adhesives.Type: GrantFiled: February 1, 1989Date of Patent: February 12, 1991Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Wolfgang Klauck, Gerhard Gierenz, Juergen Wichelhaus

Patent number: 4746696Abstract: A soft-rubbing shaped adhesive is based on an adhesive forming polymer solution gelled with a soap-forming gelling agent in the presence of a modifying additive comprising an aminocarboxylic acid or corresponding lactam, preferably an aminocarboxylic acid containing from 4 to 8 carbon atoms. Especially useful modifying additives include caprolactam, the sodium salt of aminocaproic acid, or a mixture thereof.Type: GrantFiled: February 27, 1987Date of Patent: May 24, 1988Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Gerhard Gierenz, Gabriella Kraus

Patent number: 4696836Abstract: The invention relates to a hand stamp adhesive applicator and method for applying a liquid adhesive to a defined area on a surface. The applicator includes a housing, an adhesive transfer stamp pad, a container, an adhesive applying stamp body, and a support mechanism for the stamp body. The housing includes a base and an upper part coupled to, and vertically displaceable with respect to, the base. The adhesive transfer stamp pad is supported in the housing and formed of a material permeable to the liquid adhesive. The container is also supported in the housing above, and in fluid communication with, the stamp pad. The adhesive applying stamp body applies the liquid adhesive to the defined area of the surface; and the support mechanism supports the adhesive applying stamp body in the housing for motion between an upwardly facing inoperative position to receive the liquid adhesive from the adhesive transfer stamp pad and a downwardly facing operative position to apply the liquid adhesive to the surface.Type: GrantFiled: April 2, 1986Date of Patent: September 29, 1987Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Wolfgang Dierichs, Gerhard Gierenz, Gabriella Kraus

Patent number: 4639475Abstract: The invention relates to an adhesive stick of an adhesive resin dissolved and/or dispersed in an aqueous solvent system and containing a gel-forming component and, if desired, other standard additives. The new adhesive stick is characterized in that its adhesive layers applied by rubbing onto a receiving surface show permanently tacky pressure-sensitive adhesive properties and in that the stick contains the reaction product of sorbitol and/or xylitol and benzaldehyde as the gel-forming component and, as adhesive resin, a reaction mixture from the reaction of methyl vinyl ether/maleic acid anhydride copolymers with partially neutralized acid phosphate esters of nonionic wetting agents of the lower alkylene oxide adduct type.Type: GrantFiled: April 17, 1984Date of Patent: January 27, 1987Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Wolfgang Dierichs, Gerhard Gierenz, Gabriella Kraus
