FIELD: gas apparatus, namely, high-pressure bottles made form metal-filled plastic and used in portable oxygen breathing apparatus for mountain-climbers and rescuers; fire-fighting technique, fuellers and gas supply systems. SUBSTANCE: proposed bottle has outer strength plastic envelope and inner metal hermetic linear. Side surface of liner is provided with transversal corrugations with intermediate members located between corrugations embracing the linear on the outside; these intermediate members protect corrugations under action of increased internal pressure keeping them intack. Linear construction provides for elastic compression and tension along longitudinal axis at change of internal pressure in bottle. According to one version, corrugations are formed over turns of wire by plastic deformation of linear under action of increased internal pressure. Gas passage formed in cavities between corrugations is used for check of leakage of gas in case of loss of tightness of linear. EFFECT: enhanced reliability. 21 cl
