US 4,288,000 A · Child-resistant lid for a pail

Abstract

A tightly fitting lid for a pail or bucket has a dispensing opening for discharge of the material contained in the pail and a child-resistant closure for the opening. The lid and pail constitute a package for particulate material. The lid and pail have co-operating rib and recess for retaining the lid on the pail. The lid opening is provided by a short "wide-mouth" neck which is threaded to mate with threads on the closure. The lid and closure have at least one interengaging stop and lug, respectively, which prevent the closure from being unscrewed. The closure can be removed after it is radially deformed in order to disengage the lug from the stop. The diameter of the closure is such that the closure lug cannot be disengaged from the stop by a child of tender years whose hand is too small to span the closure. The lid also has a plurality of horizontally extending webs surrounding and spaced from the closure for supporting a superposed pail.
