  • Patent number: 5009882
    Abstract: The present invention relates to compositions and methods for inhibiting plaque. In particular, this invention relates to oral compositions comprising: (a) a safe and effective amount of a plaque-inhibiting carboxy starch polymer comprising the formula ##STR1## wherein W and X are independently selected from CH.sub.2 OH, CHO and CO.sub.2 H, or the neutralized carboxylic acid salts thereof, Y and Z are independently selected from CHO and CO.sub.2 H, or the neutralized carboxylic acid salts thereof, n is in the range of from about 5 to about 2500, m is in the range of from 0 to about 2500, provided that the sum of n and m ranges from about 5 to about 2500, and the degree of carboxylation of said active agent ranges from about 1 to about 3; and (b) a pharmaceutically acceptable carrier. These compositions inhibit plaque without staining the teeth which are contacted with the composition.This invention also relates to a method of inhibiting plaque on tooth surfaces in the oral cavity.

  • Patent number: 5006004
    Abstract: A dispenser for the topical application of a liquid product. In a preferred embodiment of the present invention, the dispenser comprises a compressible reservoir, a feed tube, a smooth, substantially non-porous applicator tip, and a tip cover. Compression of the reservoir causes liquid product to flow onto the exposed surface of the applicator tip and form an encapsulating sheet of the liquid product. The liquid product may then be transferred from the applicator tip to the surface to be treated by contacting the surface with the liquid product coated applicator tip.

  • Patent number: 5004121
    Abstract: A non-metallic unitary baking pan, and especially a baking pan made of plastic, including foam plastic, paper or plastic laminated paper in which a cake or cake-like product can be baked, which baking pan has portions thereof which are thicker and have greater insulating effect than other portions to more uniformly and evenly distribute the heat produced during the baking operation throughout the cake batter or dough being baked. Also disclosed is method for producing such a non-metallic unitary baking pan by means of heated mating dies under pressure the mating dies having portions spaced farther apart than other portions thereof to produce corresponding thicker portions in the pan so formed.

  • Patent number: 4986882
    Abstract: Processes are described for making highly absorbent tissues and towels by wet-laying pulps comprising particular polycarboxylate polymer-modified fibrous pulps such as mildly hydrolyzed methyl acrylate-grafted softwood kraft pulps; these pulps have distinct protonated and alkali-metal-cation-exchanged states. The wet-laying processes are adapted to exploit the very different behavior of the polymer-modified fibrous pulps in function of the two states. The preferred wet-laying processes described herein are continuous processes embodying one or more on-line chemical treatment steps which chemically switch state of the polymer-modified fibrous pulp component in a wet web on the papermaking machine to improve the processing thereof by averting or minimizing tendencies to mechanically or thermally degrade.

  • Patent number: 4986420
    Abstract: A package having a handle for housing granular or similar products. The handle is a substantially flat strap handle which has a barb member on each end. The handle is inserted into two opposing openings in the side wall of the package. A section of the side wall adjacent each of the apertures includes a liner which separates the granular contents of the package from the area immediately surrounding the aperture. The liner is adapted to prevent the flow of granular contents out through the aperture. The package can be formed from a sleeve which, even with the handle inserted, is substantially flat. Also, with the package assembled the handle rests against the side wall of the package allowing shipping virtually as if the package did not have a handle.

  • Patent number: 4979613
    Abstract: A separable fastening device is provided for releasably fastening a first surface to a second surface. The separable fastening device comprises a first fastening element of high static vinyl material which is attached to the first surface, and a second fastening element of high static vinyl attached to the second surface. When the first fastening element and the second fastening element are placed against each other in a face-to-face relationship, the attractive forces between the first and second fastening elements form a separable bond between the first and second surfaces.
