发明名称 Beverage can having a self contained straw
摘要 The invention relates to a tab top can having a self contained drinking straw. The straw includes a resilient bellows structure on its bottom which serves to bias the top end of the straw against the underside of the tab top. A straw guide secured on the interior of the can aligns the top end of the straw with the underside of the tab top. The bellows structure forces the top end of the straw through the drinking slot formed when the tab top is removed from the can.
