  • Patent number: 5597253
    Abstract: 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.

  • Patent number: 5433775
    Abstract: 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.

  • Patent number: 5371131
    Abstract: 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.

  • Patent number: 5270433
    Abstract: The invention relates to the use of a substantially clear and at least largely solventless, aqueous, one-component polyurethane dispersion based on the reaction products ofa polyol mixture consisting completely or partly of polypropylene glycol,a mixture of polyfunctional isocyanates consisting completely or partly of .alpha.,.alpha.,.alpha.',.alpha.'-tetramethyl xylene diisocyanate (TMXDI),a functional component capable of salt formation in aqueous solution andoptionally a chain-extending agentas a universal household adhesive and to a process for its production in the absence of inert solvents.

  • Patent number: 4992500
    Abstract: 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.

  • Patent number: 4746696
    Abstract: 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.

  • Patent number: 4696836
    Abstract: 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.

  • Patent number: 4639475
    Abstract: 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.
