DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a cap operating mechanism for a cap mounted on an opening's base fixed to a container's opening so as to be pivotally opened and closed and more particularly to such mechanism utilizing a push button to open and close the cap.
BACKGROUND OF THE INVENTION
A cap operating mechanism is known, in which the cap is normally biased by a spring to be opened so that the cap is opened upon depression of a push button exclusively used to open the cap and the cap is closed against the biasing force of the spring.
However, such conventional mechanism has inconveniently required quite different actions to open the cap and to close the cap, so it is possible for a user to open the cap of a container, held in his or her one hand with the same hand, but it is impossible to close the cap in this manner.
SUMMARY OF THE INVENTION
Accordingly, it is a principal object of the invention to provide a cap operating mechanism so improved that a cap pivotally mounted on the opening's base fixed around the container's opening may be opened or closed in so-called one touch fashion by depressing a push button or the like.
To achieve the object set forth above, the invention provides a cap operating mechanism comprising a cap pivotally mounted on a container's opening, and cap rotating means provided on said cap so as to be operatively associated with depression exerted on depressor means such as a push button to rotate said cap to its opened or closed position.
The invention also provides a cap operating mechanism comprising a cap pivotally mounted on a container's opening, and cap rotating means provided on said cap so as to be operatively associated with depression exerted on single depressor means such as a single push button to rotate said cap to its opened or closed position.
The invention also provides a cap operating mechanism comprising a cap pivotally mounted on a container's opening, and cap rotating means provided on said cap so as to be operatively associated with depression exerted on a depressor exclusively used for cap opening to rotate said cap to its opened position and operatively associated with depression exerted on a depressor exclusively use for cap closing to rotate said cap to its closed position.
The invention also provides the cap operating mechanism as has been described hereinabove, wherein the depressor means is provided with elastic restoring means for elastically restoring said depressor means to its home position.
The invention also provides the cap operating mechanism including the separate depressors exclusively used for cap opening and cap closing, respectively, as has been described above, wherein these depressors operatively associated with said cap rotating means are integrated into single depressor means of seesaw type arranged so that, when one end thereof serving as one depressor is depressed around a rotating fulcrum provided on the middle of said single depressor means, the other end serving as the other depressor is automatically restored to its initial position.
The invention also provides the cap operating mechanism as has been described hereinabove, wherein the cap is rotated by the push rod member operatively associated with the depressor means.
The invention also provides a cap operating mechanism comprising a cap pivotally mounted on a container's opening, cap rotating means provided on said cap to rotate said cap to its opened or closed position by push rod means operatively associated with depressor means such as a push button, and direction selective cap biasing means adapted to bias said cap to be rotated in the direction in which the cap is opened or in the direction in which said cap is closed depending on the angular position of said cap with respect to a transitional position predetermined on the rotational stroke of said cap.
The invention also provides a cap operating mechanism comprising a cap pivotally mounted on a container's opening, cap rotating means provided on said cap to rotate said cap to its opened or closed po
