Dispensing head having a cap guard

A dispensing head having a guard cap which comprises:

• a non-rotary member, a rotary member, a nozzle tube, and a push lid, each hereunder;
• said non-rotary member having a cylindrical wall provided with a wide notch portion and supported coaxially with and non-rotatably by a dispensing container containing, under pressure, an object for dispensing, and said non-rotary member having a push button hereunder;
• said rotary member having a cylindrical wall coaxial with said cylindrical wall of said non-rotary member, said cylindrical wall of said rotary member being provided with a window bore of a size comparable with the diameter of said nozzle tube and supported, by said dispensing container, rotatably and in external contact with said cylindrical wall of said non-rotary member, and said rotary member having a range of rotation which extends from an operative position in which said window bore is located at a location in front of said push button within an angular range of said notch portion of said cylindrical wall of said non-rotary member to a non-operative position in which said window bore is located at a location within an angular range of the solid portion of said cylindrical wall of said non-rotary member;
• said push button being provided with a dispensing passage connected to the axial bore of a valve stem projecting from the top portion of said dispensing container coaxially therewith and movable in a vertical direction to control a discharge valve provided in said dispensing container, and said push button being mounted fixedly on said valve stem and supported non-rotatably by said dispensing container;
• said nozzle tube being a solid and straight tube, the base portion of which is pivoted to the front portion of said push button and connected to said dispensing passage of said push button, and said nozzle tube having a nozzle length, as measured from the center of said push button, longer than the radius of said rotary member cylindrical wall;
• said push lid covering and closing substantially the top portion of said cylindrical wall of said rotary member and being supported movable in a vertical direction to be interlockable with said push button at least in said operative position;
• one of said non-rotary member or said rotary member being provided with a key member and the other one forming a keyhole portion adapted to said key member so that said key member and said keyhole portion can form an interlocking impeding means for said push lid and said push button in said non-operative position.
