  • Patent number: 4201289
    Abstract: The disclosure is directed to a novel method of forming and packaging for display hollow, solid space air treating devices. A molten treating composition is charged into the outer shell of a thermoformed container which serves as a mold, as well as a display package for the finished product. An inner core is placed inside the outer shell displacing the molten material and forming a chamber of the shape and size of the device. A gas equalizing aperture permits release of internal pressure and excess molten material. The filled mold is cooled. The sealed container is suitable for shelf display but may have additional trade dress applied, if desired. The ultimate user removes the outer shell from the solidified device to activate the space air treatment feature.

  • Patent number: 4136825
    Abstract: The disclosure is directed to a device for sealing the neck of apparatus which utilizes a wicking action to move liquid from the interior of a container to the surrounding atmosphere. The wick is disposed about an inner core of a cellulosic material which when wetted, expands to press the wick against the sides of the orifice. The wicking action is improved and the spilling of the contents through the orifice, in the event of an upset of the container, is prevented.

  • Patent number: 3998360
    Abstract: The disclosure is directed to the combination of a container for dispensing liquid from an inverted position and a hanger device for suspending the container in an inverted position from the wall of a water closet. The hanger device consists of a planar member connected to a flanged cylindrical shaft eccentrically of the center of rotation of the shaft and opposite the flanged end. Recesses are defined in the side wall of the container to retain the shaft and in the end wall of the container to receive the planar member. The planar member and shaft swivel so that the planar member may be moved from a position where it is substantially flush with the container out to a position where it will engage the top of a wall of a water closet. The length of the shaft and the size of the recesses relative to one another may be such that the hanger device merely rotates in the recesses or such that the hanger device both rotates and reciprocates in the recesses.
