Abstract: The present invention relates to a combined apparatus for the long-term care of different kinds of plants which are placed in receptacles (soil cultures, hydroponic cultures and semihydroponic cultures should be provided with a large supply of high-quality water which is arranged in the space next to the root ball, with a possibility for optimum water level indication). The problem is solved by the device according to the invention essentially by a water-tight separating pot (10, 14,15<a>) standing inside a clay pot (7,9) having capillaries in such a manner that a section of the clay pot receives the root ball and a further section (7<b>,9<a>) "protrudes" beyond the separating pot and touches the water with the bottom, by which process the plant is supplied with water via the permanently moist clay-pot shaft (7,9), while maintaining good aeration of the roots. In a variant, the water level can be observed via a part-circular rod (6<a>) which is mounted in a pivoting point (6<d>) by means of a floating body (6<b>) and a "spoke" (6<c>). From there the indicator rod (6<a>) travels along a flat circular arc (6<g>) above the substrate/granules (11,12), depending on the water level. A flexible film/nonwoven receptacle (16) containing, inter alia, sealed-in particles of active charcoal (16<a></b>) maintains good water quality. <IMAGE>

Abstract: A non-venting propellant filling and sealing valve (10) is seated in a propellant filling hole (14) in a bottom wall (11) of a container, and permits pressurization of a container through the hole and thereafter seals the container. The valve (10) includes an umbrella sealing portion (18), a stem portion (20) and shoulder portions (25a, 25b) in a collar (24) around the stem portion (20). The umbrella sealing portion is resilient and is adapted to separate from the interior surface (46) of the bottom wall (11) of the container during pressurization and then make a generally annular seal with this surface around the hole (14). The stem portion (20) positions the umbrella sealing portion (18) around the filling hole and both it and the collar (24) have axially extending grooves therein for con- - ducting pressurizing fluid to the interior of the container. The shoulder portions (25a, 25b) of the collar (24) bear against the outer surface (42) of the bottom wall (11) to prevent the valve (10) from being blown into the container during pressurization and cause the umbrella sealing portion (18) to engage the interior surface (46) of the bottom wall. When pressurization is completed, the source of fluid is removed and the pressure inside the container, being greater than ambient, causes the umbrella sealing portion (18) to form an annular, fluid- tight seal with the interior surface (46) around the filling hole (14).
