Abstract: Container connector includes a base in which a flow path is formed, an engagement section disposed on a circle set to the base, a guiding section disposed continuously with the engagement section, and having a guide surface formed as a curved surface to guide the container to the engagement section and facing a side of an axis of the circle, and an arm provided in the base, and movably supporting the guiding section in a direction toward the axis of the circle and a direction away from the axis.

Abstract: Connection equipment includes an equipment connector comprising a first connecting section, a first liquid flow path that communicates with a equipment, and a first valve that is to open and close the first liquid flow path, a container connector comprising a second connecting section, a second liquid flow path that communicates with the container, and a second valve that is to open and close the second liquid flow path, and a lock mechanism that locks the equipment connector and the container connector in a state where the first liquid flow path is in communication with the second liquid flow path, and that unlocks the connectors in a state where the first valve and the second valve are closed.

Abstract: A lock mechanism includes an engaged section of a second member and an engagement member of a first member. The engagement member includes an operating section, a fulcrum section configured to contact the second member in a state in which the operating section is pressed, an engaging section engaging with the engaged section, a deformation section configured to be bent to move the engaging section when the operating section is pressed, and a fixing section fixed to the edge of a hole.
