1. A pressure-tight storage vessel containing a liquid, comprising:
an elongated main body which is rotationally symmetrical with respect to an axis of symmetry and which forms, at least sectionally, a rotationally symmetrical hollow space, in which a liquid is substantially received,
wherein the elongated main body is terminated at a bottom side by a base, and has an opening at a top side which is closed off in a pressure-tight manner by a closure, and
a plurality of reinforcement elements,
which bears against the elongated main body at the outside,
which extends parallel to said axis of symmetry, and
which is arranged rotationally symmetrically about said axis of symmetry such
that, in each case between adjacent reinforcement elements, respective
externally exposed wall sections of the elongated main body are formed,
wherein the composition of the externally exposed wall sections permits a pressure-tight insertion by at least two hollow needles,
wherein the main body has no separating seam and no sprue residues on the externally exposed wall sections for the pressure-tight insertion by the at least two hollow needles,
wherein the storage vessel has a border at the top side, wherein said border encircles the opening and which is spaced apart from an outer boundary of the opening,
wherein the closure is an aluminum or plastic film attached to the border by melting,
wherein the main body and the reinforcement elements comprises plastic and are produced in one piece from the plastic by an injection moulding process,
wherein the main body has a recess at a bottom side of the elongated main body, and
wherein the base is curved from the lowest point of the base extending to the inner wall of the main body,
wherein the reinforcement elements and the elongated main body extend as far as the bottom side of the storage vessel, wherein the reinforcement elements form, together with the main body, guide grooves, which are open towards the bottom side of the elongated main body, and
wherein the storage vessel has a shoulder at the top side, wherein the shoulder delimits the guide grooves towards the top side.
