Clip for sealing bag opening

The clip as claimed in 1, wherein a stopper is disposed between one end and the other end of the elastic member, and the elastic member is divided into an outer portion between the one end and the stopper and an inner portion between the stopper and the other end,

• wherein the inner portion is inserted into the inner accommodation part, wherein the stopper is hooked with an outer end of the inner accommodation part so that the inner portion is inserted only up to a predetermined position within the inner accommodation part.

The clip as claimed in 2, wherein a pair of protrusions protrude from a bottom surface of the handle part in the inner accommodation part of the handle part,

• a closed ring member is provided at the other end of the elastic member, and
• the elastic member at each of both the ends of the handle part is assembled with the handle part to accommodate one protrusion into the ring member.

The clip as claimed in 3, wherein the inner portion of the elastic member is withdrawn from the inner accommodation part, wherein the ring member is restricted by the protrusion so that the elastic member is withdrawn only up to the predetermined position outside the inner accommodation part.

The clip as claimed in 4, wherein the lowest height corresponds to a state in which the two elastic members of the movable frame are maximally inserted into the inner accommodation part so that the movable frame has the shortest length and is elastically curved downward to overlap the base,

• the intermediate height corresponds to a state in which the movable frame is maintained at the shortest length and is elastically curved upward to be spaced the intermediate height from the base, and
• the highest height corresponds to a state in which the two elastic members of the movable frame are maximally withdrawn from the inner accommodation part so that the movable frame has a maximum length and is further curved upward to be spaced the highest height from the base.

The clip as claimed in 5, wherein the movable frame is deformed in stages between the lowest height, the intermediate height, and the highest height.

The clip as claimed in 6, wherein, when the handle part of the movable frame is pulled upward from the base at the highest height, in a state in which the shortest length of the movable frame is maintained, the movable frame is elastically deformed upward to be convex so that the movable frame has the intermediate height, and

• when the handle part is further pulled upward at the intermediate height, the inner portion is withdrawn from the inner accommodation part, and the movable frame extends lengthily and is further deformed upward to be convex so that the movable frame has the highest height.

The clip as claimed in 7, wherein, when the handle part of the movable frame is pressed downward toward the base at the highest height, the inner portion is inserted into the inner accommodation part so that the movable frame approaches the base, and when the movable frame has the shortest length, the inner portion has the intermediate height, and

• when the handle part is further pressed downward at the intermediate height, in the state in which the movable frame is maintained at the shortest length, the movable frame is elastically deformed downward to be convex so that the movable frame has the lowest height.

The clip as claimed in 6, wherein, when the movable frame has the lowest height, the handle part and the base are in surface contact with each other, and a gap occurs between each of the pair of elastic members and the base.
