<P>PROBLEM TO BE SOLVED: To provide a spout cap threadably engaged with and fitted to an upper part of a liquid storing paper container which can be fixed to the liquid storing paper container without any trouble under a state in which the cap is installed in advance at the spout port, and showing a superior productivity, economic characteristic and applicability in its use in which even an aged person having a weak muscle power can easily remove the cap when the cap is to be removed. <P>SOLUTION: This spout cap is constructed such that it is formed into a shape having at least a top plate 1 and a circumferential wall 2 vertically arranged in continuous with the top plate 1. The inner circumferential surface of the circumferential wall 2 is provided with a threaded part threadably engaged with the spout. The outer circumferential surface of the circumferential wall 2 is provided longitudinal corrugations 3 for preventing a slippage of finer touch. A part of an outer surface of the top plate 1 of the cap and an outer surface of the circumferential wall 2 is arranged to have such a shape as one in which an auxiliary means for facilitating a fitting or a removal of the cap through its turning operation is not protruded substantially in a lateral direction from an outer shape of the cap. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
