Hinge system and collapsible container

A hinge system, comprises:

• a first pin and a second pin provided on a first component;
• a first slot and a second slot provided in two sides of a concave portion of a second component respectively;
• wherein
• the concave portion is formed with one side open and the second slot is formed with a first pit, a second pit being provided on one of the first slot and the second slot;
• the first pin and the second pin are not on a same axis, the first pin being movably arranged in the first slot, the second pin being movably arranged in the second slot;
• the first component selectively switches between a first position state and a second position state relative to the second component;
• when the first component stays in the first position state, the first component is inserted into the second component, the second pin is received by the first pit so as to prevent the second pin from moving towards the notch of the second slot;
• the first pin acts as a pivot shaft of the rotation of the first component with respect to the second component;
• when the first component stays in the second position state, as compared to the first position state, the first component is rotated by a predetermined angle from the open side while moving towards the notch of the first slot or the second slot by a predetermined distance, then the first pin or the second pin is received by the second pit, so that the movement of the first pin or the second pin towards to the notch of the first slot or the second slot is limited by the second pit.
