CHILD RESISTANT CLOSURE WITH RECESSED LATCH

摘要

A CHILD-RESISTANT CLOSURE (20) IS PROVIDED WITH A BASE (24) HAVING A DECK (28) WITH A DISCHARGE APERTURE (40). A LID (50) HAVING A BOTTOM SURFACE (62) FOR ENGAGING THE BASE (24) IS HINGEDLY CONNECTED TO THE BASE (24). THE BASE (24) HAS A RESILIENT LOCKING LEVER (70) THAT PROJECTS THE BASE DECK (28) AT A LOCATION INWARDLY OF THE PERIPHERY OF THE BASE (24). THE LEVER (70) DEFINES A SHOULDER (72).THE LID (50) HAS A CENTRAL COVER PANEL (58) DEFINING AN APERTURE (80) INWARDLY OF THE PERIPHERY OF THE LID (50) FOR RECEIVING THE LEVER (70) WHEN THE LID (50) IS CLOSED. THE LID (50) DEFINES A LATCH SURFACE (86) ADJACENT THE APERTURE (80) FOR CONFRONTING THE BASE LEVER SHOULDER (72) WHEN THE LID (50) IS CLOSED.THE PERIPHERY OF THE LID (50) DEFINES A FINGER-ENGAGING SURFACE (92) LATERALLY OFFSET RELATIVE TO THE LID APERTURE (80), AND THE FINGER-ENGAGING SURFACE (92) EXTENDS PROGRESSIVELY OUTWARDLY WITH INCREASING DISTANCE FROM THE LID BOTTOM SURFACE (62). THE PORTION OF THE BASE (24) THAT EXTENDS FROM THE HINGE CONNECTION (52) IS CONFIGURED TO PROJECT PERIPHERALLY OUTWARDLY AT LEAST AS FAR AS THE LID BOTTOM SURFACE (62) WHEN THE LID (50) IS CLOSED. THE PORTION OF THE LID PERIPHERY (60) THAT EXTENDS FROM THE HINGE CONNECTION (52) IS FREE OF OVERHANGING PERIPHERAL SURFACES OF SUFFICIENT DEPTH TO BE LIFTINGLY ENGAGED BY A CHILD'S TEETH.(FIG 7)
