Bulb carton and blank therefor

Abstract

This relates to an end structure for a carton, and more particularly to a carton for packaging a light bulb having a projecting base. The end structure is formed of two pairs of end panels, the first pair of end panels including two opposite disposed generally rectangular end panels having slot-like openings therein disposed in angular relation with respect to the connection between the respective end panel and a side wall of the carton. The other pair of end panels are also oppositely disposed and having sloping side edges disposed at a complimentary angle relative to the angle of the openings with respect to the fold line connecting it to the respective side wall. Each of the second end panels has a projecting tab which is lockable within the respective one of the openings. The construction is so that when the first end panels are pressed into the interior of the carton at one end, followed by the pressing of the second end panels into the carton, the tabs will automatically align with the openings and when the end panels are released, they will automatically lockingly engage in place. The relationship of the first pair of end panels within the carton and relative to the bulb base is such that even without the desired interlock with the other pair of end panels, the first pair of end panels applies a wedging action on the bulb base and prevents the release of the bulb.
