A carrier is provided with vertical support panels, each with a receptacle extending outwardly from its lower region. Each receptacle has a bottom panel which unfolds partially when the folded carrier is unfolded. An engagement structure such as a detent is provided to hold each bottom panel temporarily in the partially unfolded position to hold the receptacles open until the bottom panels are pressed downwardly by an object placed in the receptacle.
