Attached positively on a nipple (10) in the outlet opening (4) of a liquid container (2) is a non-return ball valve (22) which is arranged in a discharge pipe (36) made of a material, preferably a flexible material, which is non-expandable under operating conditions. A shutoff member (44) is arranged at the free end of the discharge pipe (36). Said shutoff member has radially arranged apertures (52, 52', 52") which, together with a cuff (54) surrounding the shutoff member, form a pressure relief valve. The non-return ball valve (22) and the shutoff member (44) are attached in the discharge pipe by means of high frequency welding. The liquid is discharged by squeezing the discharge pipe (36). This disposable packaging permits a precise, reproducible metering of the liquid. <IMAGE> |
