Abstract

A carton of the type having; first and second main panels and first and second side panels which are connected to one another so as to articulate between a knocked-down compact configuration and an open sleeve configuration. First and second main flaps hingedly are connected to the first and second main panels respectively and first and second side flaps hingedly connected to the first and second side panels respectively. Each of the flaps has a proximal end adjacent and a distal end remote from its associated main or side panel. Pour spout sub-panels are initially formed as integral parts of adjacent first main and first side flaps and are severable from the remainder of the adjacent first main and first side flaps respectively to form a pour spout in use. The adjacent first main and first side flaps each have marginal edge portions located at their distal end outwardly from the pour spout sub-panels with respect to their associatd first main and first side panels respectively. The marginal edge portions being secured to one another in a face-to-face relationship so as to cause the side flap to buckle inwardly upon itself to draw the first main flap toward an outwardly overlying relationship with respect to the first side flap as the carton moves from the knocked-down configuration to the open sleeve configuration to facilitate the closing of a first end of the carton in use.
