  • Patent number: 6854908
    Abstract: An applicator for a circular arc-shaped solid composition comprises a housing defining a conduit that is sized to accept the circular arc-shaped solid composition stick. The conduit has a first end and a second end, the second end being open, and has a continuous circular arc-shape from the first end to the second end. The housing also contains one, or more than one opening for engaging a fastener. Each one of the one, or more than one opening is of a sufficient size to permit at least partial lateral movement of the fastener. Also included in the housing are an inlet and an outlet in communication with the conduit, the outlet being in communication with the second end, and a biasing assembly for advancing the circular arc-shaped solid composition stick within the conduit. The position of the applicator of the present invention relative to a surface to be treated can be easily adjusted by laterally sliding the housing of the applicator relative to its mounting bracket.

  • Patent number: 4969927
    Abstract: A process for the machine-washing of fabrics according to which a dispensing and diffusing device of the reusable type is filled with a particulate product which is active during the washing. This device is placed in the machine together with the fabrics to be washed, and washing is subsequently carried out in the customary way. The device used comprises a flexible bag mounted on a ring made of plastic with helical radial walls providing apertures through the mouth delimited by the ring. A assembly in the form of a cage can be arranged inside the sleeve of the bag in order to maintain the form of the latter during the washing. The product dissolves progressively and little escapes from the device in solid form.
