Inflatable article with an illuminating device
 An inflatable article includes a rounded wall that encloses a first space. An illuminating device is mounted inside the rounded wall and occupies a portion of the first space. The device includes a base bonded sealingly and integrally to the rounded wall. The base confines a second space hermetically sealed from a remaining portion of the first space, and has a part exposed from the rounded wall and an opening for access to the second space. A light emitting element is disposed interiorly of the opening. A power source has a negative electrode proximate to the opening and a positive electrode connected to a first terminal of the light emitting element. A conductive member extends axially and outwardly of the power source and is connected to a second terminal of the light emitting element. A conductive cap closes the opening and is movable between a conducting position and a non-conducting position. At the conducting position, the cap engages an upper end of the conductive member to activate the emitting element. At the non-conducting position, the cap is spaced apart from the upper end of the conductive member so as to deactivate the light emitting element.
