Abstract: A cardboard blank configured for creation of a sun visor extension and sun visor produced from the blank in which a front panel and a back panel have a height approximately one-third to one-quarter larger than conventional vehicle sun visors with which the sun visor extension is to be used. A narrow bottom edge panel is connected at each of opposite sides thereof to a respective one of the front and rear panels via a folding line, a narrow outer top edge panel is connected via a folding line to an edge of the front panel that is opposite the bottom edge panel, and a narrow inner top edge panel is connected via a folding line to an edge of the back panel that is opposite the bottom edge panel. The outer top edge panel is provided with a locking tab which is connected thereto by a folding line and a receiving slot is provided at the folding line at which the inner top edge panel connects with the back panel.

Abstract: An improved water bottle design for use with a water cooler type bottled water dispensing apparatus is provided in which the water bottle includes a horizontal surface area positioned around the base of the neck of the bottle, where the bottle contacts an annular opening of the housing above an open end of a reservoir portion of the housing of the bottled water dispensing apparatus. This flat horizontal surface area results in greater stability for the water bottle on the housing than can be achieved with conventional bottles which engage the annular opening of the housing at a vertically curved surface of the bottle. Moreover, no special adapters or couplings are necessary to produce an interfit between the water bottle and the housing, and therefore, the improved stability is achieved in a very simple manner.

Abstract: A blow molded container is provided which includes a neck portion having locking teeth with features which ensure the proper formation of the teeth. Specifically, the container neck portion includes an annular inclined surface extending from both the upper and lower sides of the teeth, while all edges of the teeth are rounded. The annular inclined surfaces and the rounded edges ensure that the teeth are formed with sufficient material to ensure strong, sturdy teeth devoid of weak areas, holes or cracks. A method of forming the container is also provided which includes rounding all edges of the teeth as a parison abuts molds so as to inhibit undesirable stretching of the material forming the teeth. The method may also include forming the annular inclined surfaces to further inhibit undesirable stretching of the material forming the teeth thus ensuring proper formation of the teeth.

Abstract: A multi-functional hollow body for use as a boom rest or a boom and mast carrier for sailboats that is lightweight and may be positioned and secured to the boat without damaging the surface of its deck. The hollow body includes a neck and cap to allow it to also function as a liquid container. When the hollow body is sealed in an empty condition, it may also function as a flotation device, kickboard or a buoy.
