DRAWN CAN FOR FOOD AND THE LIKE

摘要

This relates to a can, preferably formed of aluminum, which may be formed by a drawing process and which is so constructed wherein it may utilize wall thicknesses less than those which are presently commercially permissible so as to be suitable for the packaging of food products and the like which are either hot filled or subject to retorting and still commercially compete with three-piece steel cans. A primary feature of the can is the elimination of the customary double seam securing the end unit to the can body and replacing the same with telescoping of portions of the can body and end unit and providing an adhesive bond there between with the adhesive bond being enhanced by the reaction of the can body and end unit under conditions of internal pressure and internal vacuum due to the radial compression of the adhesive forming the adhesive bond to increase the shear strength of the adhesive. The end unit is provided with a securing flange which is connected to the end panel by a corner defining a line of weakness wherein the securing flange may be torn from the end panel and at the same time peeled from the can body. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
