Luminescent balloon and method of manufacture thereof
First Claim
1. The method of fabricating a luminescent balloon comprising the steps of:
- (a) sequentially forming first and second contiguous sidewall laminations bonded to one another in face-to-face relation wherein one of the first and second sidewall laminations consists essentially of pure latex and defines the outer lamination of the balloon and the other of the first and second sidewall laminations comprises a latex lamination having luminescent mineral pigment particles distributed substantially homogeneously throughout the other lamination and defines the inner lamination of the balloon; and
,(b) sequentially drying, setting and curing the first and second sidewall laminations following formation of each lamination so as to form a cured composite laminated balloon sidewall having an outer lamination formed of essentially pure latex material providing structural integrity and an inner contiguous lamination providing luminescent characteristics.

Abstract
Luminescent balloons (18'"'"', 18") and methods of manufacture thereof wherein one or more balloon forms (11) are respectively moved through discrete sequential processing stations (12/16, 14/21 and, optionally, 15/22) for the purpose of applying successive laminations (19, 20 and, optionally, 24) on the balloon forms (11), which laminations are dryed, set and cured in drying stations (16, 21, 22) so as to form a balloon (18'"'"', 18") having: (i) an outer lamination (19) formed essentially of pure latex and providing structural integrity for the balloon; (ii) an inner lamination (20) bonded to the inner surface of the outer lamination (19), in which inner lamination (20) the luminescent dry solid particles are maintained in a latex carrier and constitute at least FIFTY PERCENT (50%), and preferably from SIXTY-FIVE PERCENT (65%) to SEVENTY-FIVE PERCENT (75%), of the total dry solids in the inner lamination (20) for imparting the luminescent qualities to the balloon; and (iii), optionally, a third essentially pure latex inner lamination (24) wherein the luminescent lamination (20) is sandwiched between the outer and inner laminations (19 and 20, respectively).

2. The method of fabricating a luminescent balloon comprising the steps of:
-
(a) forming a resilient inflatable balloon having a first sidewall lamination consisting essentially of latex; (b) drying and setting the first sidewall lamination; (c) forming a second resilient inflatable sidewall lamination in situ on the outer exposed surface of the first sidewall lamination utilizing a liquid solution containing water and a latex carrier dissolved therein, and a suspension of luminescent mineral pigment particles distributed substantially homogeneously throughout the solution; (d) drying, setting and curing the composite, laminated, resilient, inflatable balloon sidewall; and
,(e) turning the cured composite laminated balloon sidewall inside out so that the outermost exposed lamination comprises the first lamination consisting essentially of latex and the inner second lamination comprises a latex carrier and luminescent particles distributed substantially homogeneously throughout the latex carrier.
