Abstract: A canteen for use on picnics and other outings and which is capable of holding a first drink, such as water, lemonade, frozen daiquiris, etc., and which includes a cover through which the first drink may be consumed through a tubular straw member. A capsule is provided for holding a second drink; the capsule being removably held in a bracket formed on the underside of the cover, with the capsule extending down into the drink in the canteen. The capsule is previously placed in a freezer in order to freeze the second drink, so that the second drink may serve to cool the first drink during the outing. The capsule may subsequently be removed and the cool, melted second drink may be drunk through a neck formed in the upper end of the capsule.

Abstract: A holder for a frozen confection, such as an ice cream stick, or the like, which serves to hold the frozen confection in an upright position. The holder includes a trough-like upper dish which is slotted to maintain the stick of the frozen confection in an upright position, and which is shaped to catch any drips from the frozen confection as it melts. The dish fits into the open end of a cylindrical base, and it is apertured so that the collected drips from the frozen confection flow into a reservoir which is formed in the upper end of the base. The drips are accumulated in the reservoir to produce a liquid. An upwardly inclined tubular member is fitted into the side of the base and extends into the reservoir to form a drinking straw. An intermediate circular handle is formed in the tubular member.

Abstract: A canteen including a cylindrical container and a head threaded to the open top of the container, and also having a flip-up cap pivotally mounted on the head. A push-button is provided at the side of the head which, when actuated, flips up the cap to an pen position, and also pushes a spring-biased plunger away from the drinking hole to open the drinking hole. When the push-button is released, the spring-biased plunger moves to close the drinking hole. Accordingly, by operating a single push-button, the user causes the cap to flip up to an open position, and also causes the drinking hole to open, the drinking hole remaining open so long as the push-button is held by the operator in its actuated position.

Abstract: Multiple containers are provided for carrying the same or different types of food independently of one another, and which may be securely locked to one another in a compact stack for ease of carrying. The upper container is provided with a channel for receiving a utensil receptacle in a snap-fit relationship, and a utensil in the form, for example, of a plastic spoon-shaped fork is pivotally mounted to the receptacle to be turned to extend along the underside of the receptacle when the receptacle is mounted in place on the cover of the upper container, and which may be turned to extend out of the end of the receptacle when the utensil is to be used.

Abstract: A mesh bag is provided for toys, laundry and beach use, and the like, which is formed of a tubular lower portion of a mesh material, and which has an open top, a closed bottom, and overlapping sides which form a side opening. A solid fabric upper portion of the bag is secured to the lower portion and surrounds the open top of the lower portion. The solid fabric upper portion extends across the top of the overlapping sides to assist in holding the side opening in a closed condition. A plastic tube is sewn to the upper rim of the upper portion, and it serves to flatten out the sides of the upper rim and hold the top of the bag closed. A pair of upwardly-extending loop handles are attached to the upper portion on opposite sides of the bag.

Abstract: A novelty elongated handle for a child's spoon, fork or the like, which is formed of a rigid, transparent plastic material, such as acrylic. The handle is hollow to provide a transparent sealed chamber which is filled with a transparent liquid, such as water. A multiplicity of glittering particles are suspended in the liquid and float about in the liquid. The handle is constructed firmly to support the spoon, fork, or the like, at its forward end in isolated relationship from the chamber. The rear end of the handle is opened to permit the introduction of the liquid and glittering particles into the chamber. A resilient stopper is inserted into the open end of the handle and it, in turn, is covered by a plastic cap which is sealed to the rear end of the handle.

Abstract: A receptacle for a spoon and fork; The spoon and the fork are pivotally mounted to the underside to the top of the receptacle, and the top is hinged to the bottom of the receptacle so that it may be opened to permit the spoon and fork to be turned to a position in which they protrude through the ends of the receptacle, and the top may then be closed down to a snap fit with the bottom of the receptacle to hold the spoon and fork in place, and enable the receptacle to serve as a handle for the spoon and fork.

Abstract: A thermal jar for carrying snacks, and which is provided with a removable receptacle for a spoon and fork and which is received in a channel in a top surface of the cover of the jar. The spoon and the fork are pivotally mounted to the underside to the top of the receptacle, and the top is hinged to the receptacle so that it may be opened to permit the spoon and fork to be turned to a position in which they protrudes through the ends of the receptacle, and the cover may then be closed down to a snap fit with the receptacle to hold the spoon and fork in place, and enable the receptacle to serve as a handle for the spoon and fork.

Abstract: A picnic sandwich box which includes a container portion and a cover for the container. The cover has pivotally side handles which releasably engage a flange extending around the upper rim of the container. The container has a compartment formed in its upper surface for receiving disposable utensils, such as a spoon and fork. A moveable partition is mounted in the container and extends transversely across the container to serve as a divider to enable it to hold different food, for example, or fruit. The cover is preferably made of transparent plastic material, and the container portion is made of appropriate microwavable plastic, to enable food in the container to be heated after the cover has been removed.

Abstract: A child's canteen having a latched pivotally mounted cap on its top which when closed engages a spring-loaded tubular member which extends into the interior of the canteen. The cap normally holds the tubular member in a retracted position. However, when the latched cap is released, the tubular member pops up through the top of the canteen and causes the cap to swing open. The contents of the canteen may now be sucked through the tubular member.

Abstract: A decorative light switch cover for a child's room which may be easily mounted over an existing wall switch, and which serves to turn the wall switch on and off when respective actuator cords are pulled by the child. The cover also includes a decorative design with one or more moving elements that are shifted from one position to another as the wall switch is actuated. The light switch cover may be easily mounted in place over the light switch merely by removing the standard light cover by unscrewing the mounting screws, and by replacing the standard cover with the decorative cover of the invention.

Abstract: A cover assembly for a thermos, or other bottle, which includes a dispensing spout which is movable between a closed and an open position. The dispensing spout has an opening extending through it which becomes aligned with an opening in the cover when the spout is turned to its open position. The spout also includes a vent which becomes aligned with a vent in the cover when the spout is in its open position. The opening and vent in the cover are both closed and sealed by the spout when the spout is turned down to its closed position. The spout is held in its open and closed positions by a snap-acting leaf spring element which causes the spout to be snapped to its open or closed position when the spout is turned manually in one direction or the other. The dispensing spout may be used either to pour the contents out of the bottle, or to receive a drinking straw into the interior of the bottle.
