DEFINITION

Classification: 473/610

With sealable opening, valve, or inflation tube for insertion of fluid (e.g., beach ball, etc.):

(under subclass 609) Subject matter wherein the shell, core,

or bladder includes an aperture communicating between the exterior thereof and the void for the insertion or egress of fluid into or from the void and (a) a means for completely closing off the aperture to prevent reflux of fluid from the void, (b) a mechanical device located in the opening for starting, stopping, or regulating the flow of fluid into or from the void, or (c) a hollow flexible cylinder or pipe extending from the aperture, which cylinder or pipe is capable of being tied off to prevent flow of fluid into or from the void.

(1) Note. This subclass takes the combination of an opening, valve, or inflation tube and a projectile. Compare this with subclass 611 below which takes (a) an opening, valve, or inflation tube, per se, or (b) an opening, valve, or inflation tube and only so much of a projectile as is necessary to define the opening, valve, or inflation tube.
