Process for manufacturing containers for fluid products of the medical, pharmaceuticals, cosmetic type or the like, comprising the following phases: - modelling by means of an extruder die at least a layer of plastic material to form at least a substantially tubular semi-finished product having a first extremity and a second extremity; - closing said tubular semi-finished product inside a forming mould having two half-shells (6, 7), said two half-shells (6, 7) being modelled so that, when said semi-finished product is closed inside the forming mould, the first extremity of the semi-finished product is closed while the second extremity remains in fluid connection with a pneumatic nozzle; - blowing an expansion gas in said semi-finished product through said second extremity inside said forming mould (6, 7), to form at least a strip of containers, so as to provide each container with a containment body for containing at least a fluid product that, at said first extremity, extends in a closed dispensing neck and that, at said second extremity, extends in an open bottom tang, wherein the cross dimensions of said bottom tangs of the containers are substantially smaller than the cross dimensions of said containment bodies of the containers, and wherein said containers of the strip are associated removable with each other along respective first connection lines defined on said containment bodies and along respective second connection lines defined on said closing caps, with at least one of said first connection line and said second connection line being substantially longitudinal; - introducing said fluid product in said containment bodies through said bottom tangs; and - sealing said bottom tangs to form a sealing lip for each container, with the sealing lips being formed along a cross direction substantially coplanar to the lying plane of said strip and the cross dimensions of said sealing lips being substantially smaller than the cross dimensions of said containment bodies, wherein the sealing phase is performed by crushing and by sealing the open edges of the bottom tangs by means of two sealing bars. - modelling by means of an extruder die at least a layer of plastic material to form at least a substantially tubular semi-finished product having a first extremity and a second extremity; - closing said tubular semi-finished product inside a forming mould having two half-shells (6, 7), said two half-shells (6, 7) being modelled so that, when said semi-finished product is closed inside the forming mould, the first extremity of the semi-finished product is closed while the second extremity remains in fluid connection with a pneumatic nozzle; - blowing an expansion gas in said semi-finished product through said second extremity inside said forming mould (6, 7), to form at least a strip of containers, so as to provide each container with a containment body for containing at least a fluid product that, at said first extremity, extends in a closed dispensing neck and that, at said second extremity, extends in an open bottom tang, wherein the cross dimensions of said bottom tangs of the containers are substantially smaller than the cross dimensions of said containment bodies of the containers, and wherein said containers of the strip are associated removable with each other along respective first connection lines defined on said containment bodies and along respective second connection lines defined on said closing caps, with at least one of said first connection line and said second connection line being substantially longitudinal; wherein the cross dimensions of said bottom tangs of the containers are substantially smaller than the cross dimensions of said containment bodies of the containers, and wherein said containers of the strip are associated removable with each other along respective first connection lines defined on said containment bodies and along respective second connection lines defined on said closing caps, with at least one of said first connection line and said second connection line being substantially longitudinal; - introducing said fluid product in said containment bodies through said bottom tangs; and - sealing said bottom tangs to form a sealing lip for each container, with the sealing lips being formed along a cross direction substantially coplanar to the lying plane of said strip and the cross dimensions of said sealing lips being substantially smaller than the cross dimensions of said containment bodies, wherein the sealing phase is performed by crushing and by sealing the open edges of the bottom tangs by means of two sealing bars.
