US Patent 9724616 Automatic inflatable toy with housing

A self-inflatable toy having first and second housing portions and an inflatable toy body positioned there-between. The inflatable toy body having chemicals that react to produce an inflating gas. The first and second housing having beads that interact to temporarily prevent the separation of the two housings. As the toy body inflates, a pressure increases between the two housings until the increasing pressure is greater than the friction between the first and second beads causing the first housing to separate from the second housing.
