These and other advantages are provided by the inflatable air dancer

These and other advantages are provided by the inflatable air dancer structures presented herein, and which include an integral valve with two edge portions that may be formed from a single web of flexible film in an inline process. Such an inflatable air dancer structure and the associated apparatus and methods are capable of providing inflate-on-demand packaging that can be inflated using an inexpensive inflation device, and wherein such inflation is easy to do and does not require the use of an inflation needle, wand, or nozzle, or heat sealing by the entity using the packaging.

In particular, there is herein provided an inflatable air dancer structure for use in packaging comprising: at least one flexible film defining an enclosed chamber; at least one one-way valve defined at least in part by the flexible film for receiving pressurized air and thereby inflating the enclosed chamber, wherein the one-way valve comprises an external valve opening that is defined at least in part by edge portions of first and second layers of the flexible film, and further wherein the edge portions of the first and second layers of the flexible film are formed by folding the flexible film. In further respect to the invention, the one-way valve may include an internal edge portion. This internal edge portion can define a channel with one or more seals that join together the first and second layers of the flexible film. One or more slits extend through the seals so as to isolate the valve structure and make the valve resistant to leaking during movement of the inflatable air dancer structure. The seals may also be rounded proximate to the external valve opening so as to resist tearing of the flexible film at these locations. With regard to the internal edge portion, it can comprise a fold, a seal, or both a fold and a seal. An internal valve opening may be placed proximate to the internal edge portion. Additionally, the inflatable air dancer structure may define a planar direction, and the edge portions can be offset in the planar direction so as to facilitate the entry of air into the external valve opening during inflation.

The inflatable air dancer suppliers may include additional features such as sidewalls that extend from the edge portions and are connected to one another by one or more perimeter seals. Perforations can extend between the perimeter seals so as to allow for separation of the flexible film into multiple inflatable air dancer structures. Also, locator apertures can be defined between the perimeter seals for use in locating the valve of the inflatable air dancer structure proximate to the outlet of a source of pressurized air.
