Abstract: A packing container assembly having an inner and an outer elongated hollow member each having a closed end and an open end, with the open end of the inner hollow member insertable into the open end of the outer hollow member to place the hollow members in longitudinal sliding engagement. A pair of interlocking devices are formed, one on an inner surface of the outer hollow member which comprises an inwardly extending protuberance, and the other on an outer surface of the inner hollow member, which comprises a plurality of spaced depressions extending inwardly from an inner wall surface thereof. The plurality of depressions are each adapted to receive the protuberance when the two members are joined together. A pair of elongated slots extending through the wall portion of the outer hollow member are provided on each side of the protuberance to enhance the flexibility of the wall portion at the protuberance and minimize any resistance to slidability at the interface.

Abstract: For cold weather camping a sleeping bag is integrated with a hammock. The bottom side of the hammock is insulated. Padding is placed between the hammock and the occupant of the bag. Waterproof and bug covers are supported on a line above the bag. Inflatable spreaders are used in the hammock. The bag can be supported by side spreader lines attached to posts or to a cot frame. Support lines can be tightened with a turnbuckle. Insulation in the bag and below the hammock can be inflatable tube seaparated by breathable insulation. Insulation is secured to the entire bottom surface of the hammock by adhesion. Gravity hung material of appropriate material can be used in place of traditional insulating material. Appropriate moisture blocks are utilized to prevent moisture from entering the sleeping bag by way of support or other lines.

Abstract: A decorative spinner in which a hub and wind actuated blades are molded in one piece of plastic. The blades are connected to the hub by triangular spokes substantially in planes including the axis of the hub. Each spoke connects the leading and trailing edges of adjacent blades.

Abstract: A fastener for releasably securing the ends of a drawstring. The fastener has two parts, one for each end of the drawstring. The parts are held together by a dovetail connection which is separated by excessive tension in the drawstring. At least one of the parts is connected to the associated end of the drawstring by a connection which resists movements of the drawstring in the direction to enlarge or loosen the string, but is easily released to permit intentional loosening of the string.
