Zusammenfassung:	FIELD: welding processes and equipment, namely manufacture of different-purpose bottles with safety valve, for example in motor industry. SUBSTANCE: bottle includes tubular body and two covers as main members and thin membrane fluid-tightly joined with cover provided with opening and operating as sensing member. Method comprises steps of simultaneously welding cover, membrane and body by deep laser welding; clamping membrane between cover and body. Such operations allow to fluid-tightly weld membrane to cover and body and therefore to provide reliability of bottle operation. EFFECT: enhanced efficiency of bottle manufacture due to combining processes of welding on and annular-seam welding of membrane. 4 cl, 3 dwgg
