Abstract:
Thermally insulated windows and similar panel structure exposed to differential temperature conditions on opposite sides may comprise a fixed metal frame and, insulated therefrom, a movable metal frame supporting a window glass or similar panel. The movable frame is displaced into and out of venting association with and thermally insulated relationship to the fixed frame. Thermal insulation serving as weatherstripping between the frames provides a thermal barrier or break. It may be in connecting attachment to either the venting sash or the fixed frame, and in overlying relationship to the other in closed position.
Abstract:
An elastic dispensing nipple is provided which has an inwardly open annular recess in its base and a sealing disc disposed in the nipple base with the peripheral edge portion of the disc seated in the recess, the recess having a plurality of radially extending ribs on the undersurface of its top wall and on the upper surface of its bottom wall, and the disc having a plurality of radial ribs and a circumferential rib in its peripheral edge portion. An assembly of such nipple and disc is adapted to be sealed on a container entrance mouth with a shroud thereover to seal the contents in a container, and to dispense the contents of the container through the nipple after the shroud has been removed.
