A liquid container in combination with a main cap, said container having side walls and an outlet comprising a mouth and a neck of standard shape, said neck having a conical part with an outside diameter increasing downstream relative to said container, said main cap removeably attached to said container mouth by means of: a) a skirt comprising a threaded outer surface, a cylindrical inner surface sized to fit slidingly over said mouth, and an open end bevelled conically outward; and, b) a nut in threaded engagement with said skirt threaded outer surface, comprising an internal threaded surface defining a diameter and open to one end, and a ring part extending normal to said internal threaded surface and having a bearing surface facing said open one end; and, c) a split compression ring of resilient material, with a section removed to provide for decreasing diameter during compression, having a downstream outer surface in sliding contact with the bevelled open end of said skirt, an upstream end surface in circular sliding contact with the bearing surface of said ring part, and a downstream end surface of lesser diameter than said upstream end surface in angular contact with said conical part of said neck.
