  • Patent number: 5147072
    Abstract: A toggle closure for a resiliently deformable container which provides substantially continuous, uninterrupted, glug-free dispensing of liquid products. The toggle closure has two conduits, the first of which comprises a liquid discharge conduit that will always dispense liquid upon inversion of the container and the second of which comprises a vent conduit that will either dispense liquid if the container is undergoing resilient deformation tendency toward collapse during liquid dischage or, alternatively, vent air into the container during liquid dispensing if the container is not undergoing resilient deformation tendency toward collapse during liquid discharge.

  • Patent number: 5116563
    Abstract: An improved process for forming a mechanical fastening prong and the prongs produced thereby. The prongs are produced by deposition of a heated, thermally sensitive material onto a substrate, which is transported at a differential velocity relative to the heated material being deposited to form the prongs. Also, the transported substrate may be drawn away from the point of deposition at an angle. By varying the velocity differential between the substrate and the heated, thermally sensitive material as it is deposited and by varying the angle between the substrate and the point of deposition of the heated thermally sensitive material, the fastening characteristics, particularly the shear strength, of the fastening system formed of these prongs may be advantageously modified.

  • Patent number: 5116520
    Abstract: Disclosed are textile treatment compositions comprising a quaternized di-substituted imidazoline ester fabric softening compound, a nonionic fabric softening compound, and a liquid carrier. The textile treatment compositions of the present invention possess desirable storage-stability, viscosity, and fabric-conditioning properties. The compositions may be in the form of aqueous dispersions or solid compositions releasably affixed to a solid carrier.

  • Patent number: 5104568
    Abstract: 2,2'-oxodisuccinate detergent builder salts (ODS), especially tetrasodium 2,2'-oxodisuccinate, are difficult to dry and tend to pick up water due to the hygroscopicity of the 2,2'-oxodisuccinate: yet the present invention secures improved granular built detergent compositions comprising ODS by an aqueous ODS/zeolite coagglomeration process, the resulting agglomerate being remarkably stable and nonhygroscopic. Other detergent ingredients, such as perborate bleach, surfactants and the like, can be dry-mixed with the agglomerates to form fully-formulated granular detergents. The invention encompasses the agglomeration process, the ODS agglomerates and granular detergent compositions containing same.

  • Patent number: 5093170
    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 carboxy-substituted polymer active agent having the formula ##STR1## or the salts thereof, wherein R is a C.sub.1 -C.sub.8 alkyl group, n is in the range of from 0 to about 2,000, m is in the range of from about 10 to about 2,000, and p is in the range of from about 1 to about 10; and (b) a pharmaceutically acceptable carrier. These compositions inhibit plaque without staining the tooth surfaces which are contacted with the composition.This invention also relates to a method of inhibiting plaque on tooth surfaces in the oral cavity. This method involves applying a safe and effective amount of the carboxy-substituted polymer active agent to the oral cavity. Such an application is typically made by applying the above-described oral compositions containing the carboxy-substituted polymer to the tooth surface.

  • Patent number: 5073057
    Abstract: Device for applying liquid materials to the skin, said device having a liquid container, a poromeric plastic applicator head, and a diaphragm spring holding the applicator in said device. The diaphragm spring provides a liquid tight seal between the poromeric applicator head and the liquid container and also allows movement of the poromeric applicator head in a vertical direction to create a pressure within the liquid container and provide force to aid in moving the liquid through the poromeric applicator head to its outer surface. The poromeric applicator head is also provided with a capillary pressure compensating valve to maintain substantially equal pressure within and without the dispensing container.
