摘要

#CMT# #/CMT# The play ball comprises two identical hemispherical semi-shells (1) defining an internal cavity (1a) and an external volume (1b) assembled at a level of equatorial plane (1e). The internal cavity of each shell has rigidity arrangements having stiffeners. The internal stiffeners (1c, 1d) are parallel to the equatorial plane of joining and assembling of two semi-shells, and have a same thickness for balancing the ball. #CMT# : #/CMT# An independent claim is included for a method of fabricating a play ball. #CMT#USE : #/CMT# The play ball is useful in the bowl game and provence or long game. #CMT#ADVANTAGE : #/CMT# The play ball effectively provides an internal cavity, which is capable of absorbing shocks and avoiding rebound of the ball (claimed). #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a longitudinal view of two semi-shells of a play ball. 1 : Two semi-shells 1a : Internal cavity 1b : External volume 1c, 1d : Stiffeners 1e : Equatorial plane.
