ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an inflatable pillow. More particularly, the present invention relates to an inflatable pillow which has a novel means of inflation.
BACKGROUND OF THE INVENTION
Airlines, hospital emergency rooms, campers, travelers and many other entities use pillows. If a pillow is an inflatable pillow, the normal way to inflate the pillow is to blow into a closed sac through a tube and then, in some way, constrict or plug the tube in order to keep air within the pillow. This is not a convenient or necessarily rapid way to inflate a pillow.
SUMMARY OF THE INVENTION
The present invention is directed to an inflatable pillow which utilizes a ZIPLOC® bag having a regulator therein, which regulator is normally flat. When the mouth of the bag is opened and the pillow shaken, the regulator spreads the bag so as to increase its interior volume. Thereafter, when the mouth of the bag is zipped shut a quantity of air is trapped in the bag. When the bag is tilted, the regulator falls flat and a quantity of air remains trapped in the bag so as to provide a pneumatic support.
In one aspect of the invention, the regulator is a folded relatively rigid structure disposed within the bag which pushes the sides of the bag apart by bearing on internal surfaces of the bag. In another embodiment of the invention, the bag is pre-stressed so that it opens when a force is taken off the bag by, for example, but not limited to, removing the bag from an envelope or enclosing sleeve, or by simply unfolding the bag or opening the bag.
