ABSTRACT:
A tamper evident container is provided having a pouring spout which includes a shoot surface pivotally attached to a wall of the container. The shoot extends beyond and overlays an opening in the container wall to securely maintain the opening in the wall closed. The shoot includes a tip used to open the spout. A tamper evident sealing label overlays the spout and tip. The label includes a frangible sheet having an adhesive portion for attaching the label to the container surface and an adhesive free portion along a portion of an edge of a label. A tear line is provided across the label dividing the label into a first portion which includes the adhesive free portion and a second portion. The first portion overlays the tip of the spout and the second portion overlays the remaining portion of the spout. When the label is attached to the container surface the adhesive free portion may be grasped and torn away from the container to remove the first portion of the label along the tear line revealing the tip for opening the spout and leaving the second portion of the label attached to the container covering the remaining portion of the spout. When the tip is pulled away from the wall of the container to pivotally open the spout, the second portion of the label is torn.
