Abstract: An inflatable article comprises a primary inflatable portion and at least one inflatable extension connected to the primary inflatable portion. The inflatable extension has a generally hook-shaped configuration adapted for interlocking engagement with a generally hook-shaped inflatable extension of another similar inflatable article in a manner to removably interlock the articles with one another when the articles are substantially inflated.

Abstract: An article of decorative headwear comprises first and second flexible, generally gas-impermeable material. Each of the first and second sheets has a peripheral edge portion. The first and second sheets are sealed to one another at their respective peripheral edge portions to define an inflatable volume between the first and second sheets. The first and second sheets are shaped to define a primary inflatable portion and a pair of inflatable leg portions that extend from the primary inflatable portion. The inflatable leg portions are spaced from one another to define a head-receiving space between them, which is adapted for receiving a wearer's head. The inflatable leg portions are adapted for engagement with side portions of the wearer's head in a manner to retain the headwear on the wearer's head when the inflatable leg portions are inflated.
