Patent ID: 7617818

Claim:
A toy comprising: a container having a cavity containing air as a medium, wherein the cavity is sealed with a membrane that is configured to (a) enclose the medium within the cavity at a pressure of the medium below a rupture pressure, and to (b) rupture at a pressure of the medium that is greater or equal than the rupture pressure; and wherein the rupture pressure of the membrane is between 1 psi and 100 psi; wherein the container further comprises an opening portion that has a threaded first section and a threaded second section, wherein first and second sections are screwed to each other via the threaded sections, and wherein the membrane is secured and disposed between the first and second elements; a manually operable pressurizer coupled to the cavity that effects a controlled pressurization of the cavity to at least the rupture pressure; a toy projectile having a non-injurious payload, wherein the toy projectile is disposed externally to the cavity during the pressurization and propelled by the medium following rupture of the membrane; wherein the toy projectile is configured such that the projectile receives at least some of the released medium and is directly propelled by at least one of a mass momentum of the medium and a shock wave of the medium; and wherein the toy projectile is fabricated from a soft polymer or comprises a shock absorbing portion.
