With the above construction, in any case, if the lid 2 is forcibly opened as it is, the push plate 5 is stopped in the concave portion 3 by the retaining means of the push plate 5 upward. On the other hand, as a result of the lid body 2 rising, the breaking portion 4 between the lid body and the push plate 5 breaks, the restraint of the push plate 5 is released, and the push plate 5 falls out of the recess 3. . This indicates that the lid body 2 has been opened. Next, when the lid 2 is to be opened normally, if the push plate 5 is strongly pushed into the recessed portion 3, the breaking portion 4 between the lid and the push plate 5 is broken and the push plate is held. After being supported by the means, the lid 2 can be opened and closed thereafter.

Further, in the second aspect, the elastic inversion type hinge 6 in which the spout cap main body 1 and the lid body 2 are connected is elastically inverted at an intermediate portion between the lid opening and the lid closing to open in the opening direction. The lid 2 is biased in the closing direction to maintain the lid opening and lid closing positions so that the lid 2 can be poured out of the way and the lid can be closed properly, and the front edge of the lid 2 and the push plate 5 A pair of small left and right small ruptured portions 4 interposed between the ridges enable easy rupture, and locking projections 7 provided on the upper edges of both side walls of the recess 3 allow the shoulders 8 of the pressing plate 5 to be separated. Locking constitutes a simple means for preventing the push plate from slipping upward, and a locking protrusion 10 projecting from the center of the lower edge of the recess 3 holds and holds the lower edge of the pressing plate 5. A pair of left and right locking vertical projections 10 projecting from the inner portions of both side walls of the recess 3 and engaging projections attached to both side edges of the inner surface of the pressing plate 5 can be held properly in the recess 3. Article 11
Enables a reliable lid holding means that engages as the push plate 5 is pushed.
