The invention is an improved nursing bottle, providing a new valve within its bottom structure. A flexible disk is disposed within the bottom end cap of the nursing bottle, clamped at its periphery to the periphery of the base when the bottle is assembled. The disk has a ring of slits near its periphery which are closed when pressure inside the bottle equals ambient pressure. The slits are further sealed by contact with the base. Holes, which are sealed closed by contact with the disk, are provided in the base within a central portion which does not contact the slits in the disk. When pressure within the bottle drops, the disk bows upwardly in its center, opening the valve and allowing air to enter the bottle. When pressure within the bottle increases, the valve again closes.

A portable hose cart apparatus for windably holding a flexible hose and for transporting thereof. The cart includes a pair of vertical side frames shaped in the form of flanking arms each having a hub bearing surface. The frame provides a base structure for steel components that are secured by use of rotatable frame fasteners. The steel is encompassed by a seamless plastic sleeve that shrinks to the steel through a heating process. Distal ends of the steel are bound by use of a wedge shaped locking block which frictionally secures the steel tubes to forward and upper support members. A spool assembly is positioned between the frame sides forming a hose support surface therebetween, the frame sides having a shape to minimize plastic material yet maximize support when the cart is being transported.

An adjustable shelf is able to be initially attached to support structure within a storage area of a cabinet at any one of a multitude of vertical heights and then can be readily, mechanically adjusted to reposition the shelf as desired. In one embodiment, the shelf includes a pair of sprockets which are interengaged with mating slots formed in a pair of similarly constructed and laterally spaced support rails positioned within the cabinet. The drive arrangement for the sprockets can be manually, electrically or otherwise driven to provide infinite adjustments for the vertical shelf. When an electrical power motor is utilized as the drive source, the motor is preferably mounted upon a frame of the shelf and electrical power is transmitted to the motor through, at least in part, the support rail structure. In addition, the adjustable shelf carries at least one shift limiting member that can be positioned in either an in-use position, wherein the shift limiting member assures that the sprockets are maintained in engagement with the support rails, or in a release position, wherein the shelf can be either removed from or mounted upon the rails. In addition, the support rails are preferably constructed to accommodate various types of shelves in order to present a more universal, overall shelving assembly.

A spot cleaning apparatus comprises a housing, a fluid distribution system, a fluid recovery system, an agitation system, and a controller system to automatically monitor and control inputs and outputs to said systems for removal of spots and stains from a surface without attendance by a user. A suction nozzle and agitation device are mounted to the housing for movement over the surface to be cleaned relative to a stationary housing. Optionally, the spot cleaning apparatus can be operated in a manual mode.
