ABSTRACT:
A single lamp bulb is retained within a collapsible open-ended tubular sleeve of stiff paperboard by an integral panel that extends within the interior of the sleeve and has a medial cut-out which interlockingly accommodates a protruding arcuate portion of the lamp bulb. The locking panel is slit, scored and secured to only one of the sleeve walls in such a manner that it automatically flexes and is pushed into locking position when the sleeve is set up for use. The central portion of the panel obliquely spans a corner of the erected sleeve and another portion of the panel frictionally engages and is wedged against one of the sleeve walls to provide a bracing action that inhibits the inherent tendency of the sleeve to return to collapsed condition.
