ABSTRACT:
An unloader for removing hollow articles packed for shipment in nested layers is disclosed. The unloader includes retainer elements configured to engage interior surfaces of the hollow articles. Retentive forces arising from engagement of surfaces of the retainer elements with interior surfaces of the hollow articles as the retainer elements are inserted into the hollow articles are utilized to hold the articles on the retainer elements. Such forces can result from the deformation of elastic retaining elements as they are inserted into the article. A member or members associated with the unloader disengage the hollow articles from the unloader in a manner such that the hollow articles can be set down in an organized fashion. The embodiment disclosed is hand-manipulable.
