A clamshell type carton bottom having integrally connected thereto a domed top with upper portions of side and front panels of the carton bottom defining seats on which there are seated seat members carried by side and front panels of the top and reversely turned so as to slope upwardly and outwardly while the side and front panels slope downwardly and outwardly. Each side panel of the bottom adjacent the front panel of the bottom is provided with a cut line which defines stop means so as to limit the movement of the top into the bottom when the carton is being closed. Further, the bottom front panel is provided with a locking flap which carries a locking tab which engages over the front seat member of the top to lock the top in place relative to the bottom.

Clamshell style carton

This relates to a carton for dispensing plastic film wherein the carton is provided on a front wall of the bottom thereof with adhesive to hold the projecting portion of the plastic film in place after a preceding portion had been severed from the roll. In lieu of the customary adhesive spot, there is a printed, registered, continuous film coating of adhesive on the front wall. There is also a resist coating applied to the opposite face of the front wall so that when the carton is in a blank form and recently coated cartons overlie one another, the front panel of one carton not stick to the rear surface of the front panel of the next carton. The release or resist coating is in a pattern whereby when a reinforcing flap carried by the front panel is reversely turned and glued in place, it will stick to the rear surface of the front panel.

Blank for carton for holding and dispensing plastic film

A tray-type container and a method of forming the same container is disclosed which is formed from a single blank of paperboard having a coating of a heat sealable film material so as to provide when fully set up, a rectangular bottom wall forming panel with hingedly connected upstanding sidewall and end wall forming panels which are integrally connected at the corners by pairs of triangular web members folded upon each other and against the outside faces of the end walls where they are secured by narrow top edge reinforcing and stiffening strips folded downwardly of the top edge into overlying relation with the top portions of the folded web members and the end wall, which reinforcing strips are heat sealed to corner connecting tab members folded with the corner web members into position beneath the strips.
