Abstract

Abstract A COATED GLASS BOTTLE DESIGNED TO PREVENT SCATTERING OF THE BROKEL GLASS UPON BREAKAGE IS PROVIDED HEREIN, SAID COATED GLASS BOTTLE CONTAINING A MULTILAYER PROTECTIVE FILM ON ITS SURFACE, THE FIRST OR INNER FILM BEING A HIGH POLYMER HAVING A MOSERATE ADHESIVE STRENGTH OF E.G. 0.1 KG./CM. TO 3.0 KG./CM. WITH RESPECT TO THE GLASS SURFACE AND CAPABLE OF BEING STRECHED TO AN EXTENT GREATER THAN 150% OF THE ORIGINAL LENGTH OF THE FILM AND EXEMPLIFIED BY SUCH MATERIALS AS NATURAL RUBBER, AND AN OUTER PROTECTIVE COATING OF A SYNTHETIC RESIN COVERING THE ENTIRE SURFACE OF THE INNER FILM, SAID OUTER FILM BEING SUCH MATERIALS AS EPOXY RESINS, POLYURETHANE, ECT., HAVING A MECHANICAL STRENGTH GREATER THAN ABOUT 200 KG./CM.2, AND HAVING SUCH PROPERTIES AS WATER-RESISTANCE, OIL-RESISTANCE, ECT., AND WHEREIN THE ADHESIVE STRENGTH BETWEEN THE INNER AND OUTER FILM IS EQUAL TO THE ADHESIVE STRENGTH BETWEEN THE GLASS BOTTLE AND THE INNER FILM. A METHOD OF PREPARING SAID COATED BOTTLES ARE ESPECIALLY SUITED VIDED HEREIN.
