There are described bottle cap assemblies. In some embodiments, a bottle cap assembly includes a cap which is snappingly engagable to a bottle and disengageable by rotating the cap and the bottle relative to one another, squeezing the cap suitably and pulling the cap away from the bottle.
Claims14
A bottle cap assembly comprising:
- a bottle having a base and a wall axially extending from a periphery of the base and leading to a neck finish, the neck finish having at least two circumferentially spaced-apart shoulders protruding from an exterior circumference of the neck finish, and at least two circumferentially spaced-apart grooves recessing from the exterior circumference, the grooves being axially closer to the base than the shoulders, each groove being circumferentially aligned with a corresponding one of the shoulders so as to define at least one pair of diametrically opposite slots around the exterior circumference;
- and a cap having a top and a wall axially extending from a periphery of the top and leading to a circular contour, the cap having first and second snap engagement means protruding inwardly from an interior circumference of the wall of the cap in proximity to the circular contour, the first snap engagement means having a first radial protrusion length, the second snap engagement means having at least one pair of snap engagement members being diametrically opposite to one another around the interior circumference, the at least one pair of snap engagement members having a second radial protrusion length exceeding the first radial protrusion length, the cap being snappingly engageable to the bottle by forcing the first and second snap engagement means of the cap over the shoulders so as to secure at least the first snap engagement means in the grooves of the bottle, and the cap being disengageable from the bottle by squeezing the cap at at least one pair of diametrically opposite points corresponding to the slots of the bottle thereby deforming the circular contour into an ovoid contour allowing the first and second snap engagement means to be unsecured from the grooves of the bottle which thereafter allows pulling the cap away from bottle.
A method of disengaging a cap from a bottle, the bottle having a base and a wall axially extending from a periphery of the base and leading to a neck finish, the neck finish having at least two circumferentially spaced-apart shoulders protruding from an exterior circumference of the neck finish, and at least two circumferentially spaced-apart grooves recessing from the exterior circumference, the grooves being axially closer to the base than the shoulders, each groove being circumferentially aligned with a corresponding one of the shoulders so as to define at least one pair of diametrically opposite slots around the exterior circumference;
- and the cap having a top and a wall axially extending from a periphery of the top and leading to a circular contour, the cap having first and second snap engagement means protruding inwardly from an interior circumference of the wall of the cap in proximity to the circular contour, the first snap engagement means having a first radial protrusion length, the second snap engagement means having at least one pair of snap engagement members being diametrically opposite to one another around the interior circumference, the snap engagement members having a second radial protrusion length exceeding the first radial protrusion length, the method comprising:
- squeezing the cap at at least one pair of diametrically opposite points corresponding to the slots of the bottle thereby deforming the circular contour into an ovoid contour allowing the first and second snap engagement means to be unsecured from the grooves of the bottle;
- and
- pulling the cap away from bottle.
