Container lid having opening identification function

A container lid having an opening identification function, the container lid comprising:

• a base member formed in a hollow shape and coupled to a container body having an open upper portion along an upper circumference of the container body;
• a cover member configured to open or close an upper portion of the base member;
• a hinge member configured to connect a rear side of the base member and a rear side of the cover member to each other to allow the cover member to rotate up and down with respect to the base member so as to open or close the upper portion of the container body;
• a handle portion protruding from a front side of the cover member;
• and
• a fracture member configured to connect the upper portion of the base member and a lower portion of the cover member, which face each other, before the cover member is opened with respect to the base member,
• wherein the upper portion of the base member has an avoidance groove formed concavely downward,
• the fracture member is disposed in the avoidance groove,
• the fracture member includes:
• a first support portion having one end connected to a bottom surface of the avoidance groove;
• a second support portion having one end connected to the lower portion of the cover member;
• and
• a connection portion configured to connect the other end of the first support portion and the other end of the second support portion to each other,
• the one end of the first support portion and the one end of the second support portion are disposed adjacent to each other in a direction in which the handle portion is formed,
• the connection portion is disposed in a direction opposite to the direction in which the handle portion is formed on a basis of to the first support portion and the second support portion, so that the connection portion is disposed at a position farthest from the handle portion in the fracture member, and
• when the cover member is opened by initially rotating up with respect to the base member by an external force, the fracture member is plastically deformed while being deployed and extended up and down, and is cut.
