Container with lock device for ring-shaped objects

A container for securely holding a ring-shaped object, comprising:

• a body having:
• a front face,
• opposite said front face
• a slot which is indented in said front face and defined between first and second inner side walls for receiving the ring-shaped object in said slot while at least a portion of the ring-shaped object is positioned between said first and second inner sides walls,
• a bracket, which is formed inside said body, communicating with said slot through a wall opening in said first inner side wall and communicating with the outside of the body through a surface opening opened in said rear face;
• and
• a lock device which comprises:
• an arm which is disposed in said body to slide along said bracket,
• a rigid member provided at one end of said arm, and
• a button which is connected to another end of said arm and movably mounted in said bracket, wherein said button is operable through said surface opening in said rear face of said body so as to operate said rigid member between a lock position and an unlock position;
• wherein by moving said button in a direction towards said slot via said surface opening on said rear face of said body, said rigid member is driven by said arm to said lock position that said rigid member is inserted into said slot through said wall opening of said first inner side wall for axially extending through the ring-shaped object for locking the ring-shaped object in position and preventing the ring-shaped object from removing from said slot;
• wherein by moving said button in a direction away from said slot via said surface opening on said rear face of said body, said rigid member is driven by said arm to said unlock position that said rigid member is removed from said slot into said bracket through said wall opening for unlocking the ring-shaped object so that the ring-shaped object is capable of being removed from said slot.
