Abstract: A duck house for Wood Ducks is formed of two double walled, half cylindrical sections and a double wall bowl. Each cylindrical half section carries hinge elements on its sides to enable the front section to be opened about either side edge thereof for inspection and cleaning. The other or rear section is readily attached to either a wooden post, a tree, a barn, or a metal post. Each section is formed of plastics by conventional blow molding equipment and exhibits thermal insulation properties to produce slower changes in interior temperature than changes in ambient temperature. The shape and dimensions of the house are such as to display resistance to predators. The interior of the front section is provided with steps to permit duckling egress from the house.

Abstract: A drawer construction including a drawer front and a drawer frame, wherein the drawer front is a unitary, hollow, blow-molded thermoplastic member and the drawer frame is of sheet metal. The drawer frame is defined by a bottom wall, a rear wall and two side walls. The front of the bottom wall is bent upwardly ninety degrees, and the free edge of this bent portion is gripped by spaced, downwardly extending tabs, the latter being integral with the drawer front. Similarly, the front portions of the drawer frame side walls are bent inwardly ninety degrees and each upper free edge portion thereof is gripped by a respective tab integral with the drawer frame. The drawer front and drawer frame are held together in correct relationship by fasteners extending from the drawer frame into the rear wall portion of the drawer front.

Abstract: A portable utility tray formed from a resilient thermoplastic material, such as polyethylene. The tray is provided with one or more continuous upward protrusions, of generally inverted V-shape, with one of the protrusions defining a raised rib running centrally and longitudinally of the tray. The top of the rib is provided with sockets to receive pintles carried by a handle pivotally mounted on the rib top, the handle being rotatable over approximately 180.degree.. The handle and rib are provided with cooperating dimple and detent elements to releasably hold the handle in an upright position. The handle may be swung in either of two substantially flat positions, with the handle being releasably held in either of its two extreme, substantially flat positions. The tray is formed by blow molding a preform, to form a double-wall tray, and then cutting off and removing the inner bottom one of double walls.

Abstract: An insulated bottle holder defined by an outer shell of a moldable, resilient plastic material and an inner, removable insulating liner inside of a lower, cylindrical portion of the outer shell. The uppermost portion of the shell is conical, being truncated and flat at its top, the flat top defined by a deformable wall having a bottle ring engaging opening. A bottle is inserted into the open bottom of the holder and is pushed upwardly until the bottle threads and ring pass through and extend slightly beyond the opening in the deformable wall. The periphery of the top opening releasably holds the bottle in the bottle holder by snugly engaging the neck of the bottle just below the ring, the ring abutting the upper periphery of the top opening in the deformable wall. Friction between the bottle and the liner also holds the bottle in the holder shell. The bottle is removed by forcing it downwardly against the deformable wall.

Abstract: A storage case for a video cassette. The case is in the general form at a book and is openable to a flat condition. A hollow wall, blow-molded construction imparts structural rigidity to the case and also provides shock resistance for its contents. The case is formed by blow molding a single, unitary, hollow parison of a thermoplastic material and then pressing two parallel portions of the blow-molded article to form living hinges. Integral resilient latch elements hold the case closed yet permit easy reopening. The case is formed in an essentially single operation.

Abstract: An insulated can holder defined by an outer shell of a moldable, resilient plastic material and an inner, removable insulating liner inside of the outer shell. The shell carries at least one flat, indicia bearing and integral portion whose interior surface bears against the insulating liner to thereby define a nin-circular cross section of the holder and thereby increase the contact and friction between a can and the liner.

Abstract: A container case includes a cover, a base and a hinge which pivotally joins the cover and the base on a corresponding side of each. The cover, base and hinge are formed by blow molding. The cover and base are double-walled in construction and identical so that they can be formed from the same mold. Each of the cover and base includes cylindrically-shaped, hollow extensions which form portions of the hinge. When the case is assembled, alternate hinge portions of the cover and base are aligned end-to-end along a common axis and cooperatingly mate to form the full hinge. The hinge is drilled to form openings in the end surfaces of the mating hinge portions which communicate with the interior, hollow areas of the hinge portions to form a single bore through the entire axial length of the hinge. A polyethylene pin is received by the hinge bore to interlock the individual hinge portions.

Abstract: A hinged cover, of double wall construction, for a container. The container base is configured to carry a portable saw. This invention resides in a cover construction which permits the storage of a spare rotary saw blade. The blade is stored in such a manner that irregular random or jostling motion of the closed container, such as rough transport of the container over a period of time, cannot result in the teeth of the stored saw blade piercing or damaging the exterior wall of the cover.
