Abstract
Here is disclosed a cutter lid for a container hermetically filled with fluid content such as liquid food, e.g., stew, or granular food, e.g., table salt, characterized by that there is provided a cutter member including a knife edge adapted to cut into a top cover of the container as a foldable and rotatable grip is folded upwards. Upon raising the cutter member with the grip held, the knife edge of said cutter member cuts into the top cover of the container and rotation of the grip opens the top cover. In contrast with the pull-open type cutter lid of prior art, there is produced no force causing the container to be vertically moved and therefore the top cover of the container can be opened without any splashing of the fluid content. Furthermore, the rotatable disc provided on the upper side of the top cover to rotate the cutter member serves also as reinforcing means and decorative means for the top cover.
