Abstract
A tongue and groove arrangement guides an outer cap in an axial direction with respect to an inner cap. When a cap is fixed to a mouth of a container body, the outer cap is located in a direction of separating from the inner cap in the axial direction, and an inner face of a top wall of the outer cap is separated from a valve to urge the valve in a direction of projecting from a discharge hole of an inside plug, causing the discharge hole to close. When the cap is detached and removed from the mouth, the outer cap is moved in a direction of approaching the inner cap in the axial direction, and the inner face abuts the valve urged in a direction of separating from the discharge hole while resisting against an urging member, causing the discharge hole to open.
Claims12
A coating container comprising:
- an inside plug member fixed to a mouth part of a container body and including a leading end;
- a valve element disposed at the inside plug member, the valve element being capable of projecting from and withdrawing into a discharge hole formed at the leading end of the inside plug member and being urged in a direction of projecting from the discharge hole by an urging member, such that the discharge hole is opened and closed by a movement of the valve element;
- and
- a cap member detachably fixed to the mouth part of the container body,
- wherein the cap member comprises:
- an inner cap member detachably fixed to the mouth part of the container body;
- an outer cap member fixed to an outside of the inner cap member;
- and
- a guiding means for guiding the outer cap member to be movable in a moving direction of the valve element with respect to the inner cap member,
- wherein, the outer cap member is movable relatively in the moving direction of the valve element with respect to the inner cap member and is movable between (i) a separating position in which a guiding member of the outer cap member is located in an upper end top position and (ii) an approaching position in which the guiding member of the outer cap member is located in a lower end position,
- wherein, when the cap member is fixed to the mouth part of the container body, the outer cap member is located in a direction of separating from the inner cap member in the moving direction of the valve element with the guiding member of the outer cap member in the upper end top position, and an inner face of a top wall of the outer cap member is separated from the valve element so as to urge the valve element in a direction of projecting from the discharge hole of the inside plug member, such that the discharge hole is in a closed state,
- wherein, when the cap member is detached from the mouth part of the container body, the outer cap member is moved in a direction of approaching the inner cap member in the moving direction of the valve element with the guiding member of the outer cap member in the lower end position, and the inner face of the top wall of the outer cap member abuts the valve element so as to urge the valve element in a direction of withdrawing into and separating from the discharge hole of the inside plug member while resisting against an urging force of the urging member, such that the discharge hole is in an opened state, and
- wherein, when the cap member is detached and separated from the mouth part of the container body, the valve element is urged in the direction of projecting from the discharge hole of the inside plug member by the urging force of the urging member, such that the discharge hole is in the closed state.
