OUTLET BASE OF LIQUID FILLED CONTAINER HAVING AIR DISCHARGE STRUCTURE

摘要

PURPOSE: An outlet base is provided to achieve a consumer convenience and reduce cost while allowing the liquid container to be filled with contents at a high speed. CONSTITUTION: An outlet base comprises an adhesion pipe portion(1), an outlet pipe portion(2), and a cap(3). The adhesion pipe portion has at an entrance thereof a plurality of screw threads and at an inner side thereof a protrusion(14) and sealing portions(15,17). The outlet base has an adhesion portion(7) for an attachment to the main body of the container. The outlet pipe portion has at an outlet opening a protrusion sealing portion, at a side surface thereof a protrusion(13), closing/opening protrusions(4,5) and a hole(6). When the outlet pipe portion is press-inserted into the adhesion pipe portion, an air within the container escapes upon filling the container with contents.
