Kind Code:
B2
Abstract:
PURPOSE: To form an opening assuredly at a location with a step for a folding line, and make the taking out of a content easier by providing a plurality of ribs in the direction which is orthogonal to a linear half-cut being provided on a rigid lid.
CONSTITUTION: A lid 2 is bent to a container 3 side in parallel with a half-cut 5 while holding the end edge of the lid 2 by a finger. By doing this, the lid 2 is torn off from the half-cut part 5 in the vicinity of a crossing part between the half-cut 5 and the upper edge of a step part 6 being provided on the lid 2, and an opening is formed. From the opening, a content in the container is discharged to the outside and can be taken out. When the lid 2 is bent to the container 3 side, the rigidity of the lid 2 becomes larger by ribs 7a-7c being provided on the lid 2, and the deflection of the lid is reduced. Therefore, a stress due to the bending is concentrated in the vicinity of the crossing part between the half-cut 5 and the upper edge of the step 6 provided on the lid, and the forming of an opening becomes easier.
