FIELD: production of plastic reservoirs. SUBSTANCE: reservoir has hole and cover for closing this hole. Body and cover of reservoir are manufactured at one stage by injection moulding in form of billet whose both parts are interconnected by means of hinge. Then billet is subjected to further treatment till required reservoir is made. Billet is made in form of tubular body with open opposite end. Tubular body of billet is subjected to extending. Method makes it possible to manufacture tube together with cap at one stage and to align its shape at stage of subsequent treatment. EFFECT: enhanced efficiency. 5 cl, 2 dwg
