Abstract: An improved light weight liquid-containing stackable bottle made of plastic such as polycarbonate. The bottle is preferably of rectangular cross-section with parallel oppositely disposed mating sides which permits secure and space-saving stacking of the bottles. Complementary projections and receptacles are formed in the mating sides of the bottle to permit interlocking of the bottles when they are stacked. Desirably, vertical and horizontal corrugation are formed in the sides of the bottle to provide strength and reinforcement against both sideways and axial forces. The non-parallel corrugations preferably do not intersect to avoid the creation of stress points which could lead to cracking and flaws in the bottles. Horizontal corrugations are remote from the bottom and shoulder parts of the bottle in order to improve impact resistance.

Abstract: The invention comprises a nestable-extendable apparatus for dispensing fluids from a container. The dispensing apparatus is nestable--i.e., capable of being collapsed or inverted into the container when not in use and extended or telescoped therefrom when needed to dispense fluid. The apparatus includes a selectively operable dispensing valve at the outboard end of a flexible, extendable, nestable member preferably of generally circular cross section and generally conical longitudinal section. The dispensing valve can be "nested", or collapsed into the container by inverting the membrane within itself into the container, and can be "telescoped" or extended by manually pulling the valve and membrane into the extended position by means of a pull-out ring. The dispensing valve can be collapsed into an opening in the container wall. The dispensing valve of the preferred embodiment may be opened by pressing a button with the thumb.

Abstract: A closure and sealing device for closing and sealing an open-mouthed vessel having a vessel neck and further having an orifice defined by a vessel neck lip protruding axially and radially from said orifice. A bottle cap in accordance with the preferred embodiment is designed to prevent the transfer of liquid or gas between the interior of the bottle and the atmosphere and includes two elongated, tapered sealing members disposed around the interior perimeter of the cap with the sealing members angularly disposed such that they diverge from each other. The tapered ends of the elongated sealing members are adapted to make firm contact against the top and side of the lip. Seal augmenting means consisting of a relatively massive protruding region disposed around the interior perimeter of the cap below the sealing members are adapted to urge the sealing members into sealing contact with the lip and acts as a third sealing member.

Abstract: A filter element is provided at the inlet of a spigot for dispensing beverages from a reservoir or cooler. The filter mechanism preferably includes an open, cup-shaped member which is desirably threaded to the inlet shaft of the spigot to act as a fastener for mounting the spigot to the reservoir. The filter element is quickly insertable into and removable from the filter receiving member by a push fit. The preferred filter element includes two apertured end walls, filter paper positioned immediately adjacent the inner faces of each of the apertured end plates, and activated charcoal between the filter paper.

Abstract: A case for a five gallon water bottle has an internal abutment cooperating with a raised bead on the bottle to prevent inadvertent or accidental removal of the bottle from the case. The bottle for its removal requires its neck portion to be raised manually sufficiently such that such bead may ride over or clear such abutment. Such neck portion is cylindrical and is sufficiently prolonged between raised portions to allow a person to wrap four fingers of his hand around such cylindrical portion for easier and safer handling of the bottle.

Abstract: A combination sealing, venting, mounting and filter element is positioned between a replaceable inverted water bottle and a water reservoir from which the water is dispensed. The element is snugly fitted within the mouth portion of the reservoir or olla of plastic material into which a dispensing valve is threaded. The element includes a venting channel in communication with a filter housing which is releasably secured to such element adjacent to an upwardly extending flange portion, the flanged portion being apertured for venting and also shaped to provide a sealing portion engaging the bottle. Also the element has a downwardly extending portion near its periphery for engagement of a flat surface of a housing for the reservoir.

Abstract: A plastic carrying case is constructed with a special elevated center divider and an inner depressed ledge portion and also with a special lower grooved portion that allows the center divider of a lower case to enter and be guided by the lower grooved portion of an upper case to facilitate movement of an upper case onto the ledge portion of the lower case. There is a special interrelationship between the center divider and the lower grooved portion of an adjacent case that assures rigidity yet facilitates intentional removal. The case walls are of thin construction for economy reinforced, however, by vertical beads through which compressive forces are transmitted.

Abstract: A water spigot has a quickly attachable and detachable nozzle for sanitary, assembly and constructional purposes. The nozzle besides producing a uniform flow denys access to the valve element and its actuator thereby greatly minimizing possibility of contamination which otherwise exists by persons who are inclined to touch the valve element and/or its actuator in prior art spigots. The nozzle is quickly attachable and detachable for assembly purposes and testing in original manufactive and, if desired, in subsequent repair. The construction is such that the valve actuator, in the form of a wire, is no longer required to be as long as in prior art spigots thereby minimizing mechanical problems and resulting in a more trouble free sanitary spigot.

Abstract: A collapsible carton is provided with two bottom closure flaps. A center divider is also provided which has its bottom edge extended along the junction between the two bottom flaps. This center divider and the two bottom flaps have intermeshing apertured projections. Each projection has a cylindrical hole extending therethrough and all said projections are alignable to receive a single securing pin.

Abstract: A combination sealing, venting, mounting and filter element is positioned between a replaceable inverted water bottle and a water reservoir from which the water is dispensed. The element is snugly fitted within the mouth portion of the reservoir or olla of plastic material into which a dispensng valve is threaded. The element includes a venting channel in communication with a filter housing which is releasably secured to such element adjacent to an upwardly extending flange portion, the flanged portion being apertured for venting and also shaped to provide a sealing portion engaging the bottle. Also the element has a downwardly extending portion near its periphery for engagement of a flat surface of a housing for the reservoir.
