Abstract: A toy milkable figure representative of an animal of the type capable of dispensing milk. The figure has a pivotally mounted head which may be pushed downwardly from an upper position to a lower position where a mouth opening in the head is immersed in liquid. The figure has a pivotally mounted tail which may be pumped up and down to create a liquid pumping action. The figure has an udder that forms a liquid holding chamber and has one or more flexible and squeezable teats. When the head is lowered into the liquid supply and the tail pumped, liquid is drawn into the mouth opening and delivered into the udder chamber. A liquid intake limiting mechanism causes the head to automatically raise out of the liquid after a predetermined amount of pumping.

Abstract: An articulated hinge having a movable pivot axis cooperates with an energy storage device for automatically opening and securing an unlatched compartment door in a first open position. Primary and secondary linking members are rotatively mounted to a support structure adjacent the interior of the compartment door opening, and are also rotatively mounted on a hinge base member. The hinge base member forms a pivot axis about which the compartment door is mounted for rotation.
