After each dispensing operation the cap may
be manually rocked back on its hinge pin, and
when the cap becomes aligned with the neck
the cap may be then screwed tight upon the neck
without the necessity for iinding the proper

In Figures 6, 7 and 8 the projection 30 which
carries the hinge eye opening 29 is attached to
the neck of the container while the pin is at

neck the pin passes in the clearance rspace pro
