  • Publication number: 20130291390
    Abstract: A shaving razor comprising a handle comprising a head portion, a tail portion opposite the head portion, and a grip portion disposed between the head portion and the tail portion. The grip portion comprises an inner shaft spanning a length of the grip portion; an outer shaft coupled to the inner shaft, the outer shaft configured to be rotationally asymmetric to the inner shaft such that the outer shaft is not free to rotate about an axis along the length of the grip portion; and a gel grip coupled to the outer shaft, the gel grip having a Shore 000 hardness of less than about 80.

  • Patent number: 8507061
    Abstract: A blow molded article comprising a housing defining a hollow interior. The housing comprises a blow molded thermoplastic polymer and a thermoplastic elastomer on a portion of the blow molded thermoplastic polymer. The thermoplastic elastomer is polar and hydrophilic. A coefficient of friction of the thermoplastic elastomer when wet is higher than a coefficient of friction of the blow molded thermoplastic polymer when wet.

  • Publication number: 20090293292
    Abstract: A razor handle including a support member. The support member has a first end, an opposed second end and a middle portion extending between the first end and the second end. The middle portion has a U-shaped cross-section extending along its length. The U-shaped cross-section has a concave inner channel portion and a convex outer portion. A first resilient layer is positioned in the concave inner channel portion. The first resilient layer is more resilient than the support member. A second resilient layer is positioned on the convex outer portion. The second resilient layer is more resilient than the support member.

  • Patent number: 5013361
    Abstract: Aqueous based shear-thinning ink compositions and ball-point pens including the ink compositions. The ink compositions have a shear thinning index of from about 0.01 to about 0.6 and include colorant material(s) and a water dispersible, polymeric shear-thinning material substantially uniformly dispersed in a highly polar solvent system in which water is the primary solvent for the shear-thinning material.

  • Patent number: 4567246
    Abstract: Disclosed are carboxylic acid containing polymeric microgel particles which are prepared by polymerizing in aqueous emulsion a monomer mixture containing about 10-50% by weight of polymerizable carboxylic acid monomers, up to 5% of a difunctional crosslinking monomer and one or more carboxyl-free relatively water insoluble polymerizable vinyl monomers. The resulting microgel particles are water-swellable and may be employed as stabilizers for use in the preparation of aqueous dispersions of film-forming resins containing smaller amounts of organic solvents than conventional aqueous dispersions of this type. Such dispersions are useful as coating compositions, yielding coatings having less water sensitivity and improved adhesion as compared with coatings obtained from conventional aqueous dispersions of film-forming resins.
