A valve having a valve body, defining a longitudinal axis, with a circular side wall extending down beyond a floor of the body to define a socket. Into this socket is frictionally engaged an appendage having a circular upper end and a nipple at its lower end. The appendage is partitioned into a primary product passage, communicating with a product outlet extending through the floor of the valve body, and a ball chamber, the lower of which is provided with a valve seat with a bypass opening communicating with the primary product passage. A ball chamber passage is formed in the ball chamber above the valve seat and a ball is normally seated, via gravity, on the valve seat when the container is in a normal upright position. When the container is inverted, the ball drops away from the seat and permits passage of product through the ball chamber passage, through the bypass opening into the primary product passage and up into the valve body for discharge. At least one of a ball chamber longitudinal axis and a ball chamber plane is inclined relative to the longitudinal axis defined by the remainder of the valve to alter the degree of permissible tilt of a container containing the valve before the ball becomes unseated.

[ Wherefore, we claim:] [1.] An invertible valve comprising a valve body accommodating a valve element for controlling flow through the valve, the valve body defining a valve body longitudinal axis, the valve element having passage means, communicating with a product passage, for discharging product
[ Wherefore, we claim:] [1.] An invertible valve comprising a valve body accommodating a valve element for controlling flow through the valve, the valve body defining a valve body longitudinal axis, the valve element having passage means, communicating with a product passage, for discharging product from the valve when the valve is opened, the valve body having a socket, at a lower end thereof, containing a product outlet, the socket receiving an appendage having a ball chamber and a valve inlet product passage, the ball chamber being provided with a ball chamber passage and a ball chamber bypass valve seat having a ball chamber bypass opening, a lower end of the product passage communicating with the ball chamber bypass opening while an upper end thereof communicating, via the product outlet of the socket, with the valve element, and a gravity-responsive ball chamber ball being provided in the ball chamber and normally seating on the ball chamber seat, the ball chamber providing an area for accommodating the ball when the ball becomes unseated from the ball chamber seat, a perimeter contact between the ball chamber seat and the ball, when the ball is supported thereby, defining a ball chamber plane, and the ball chamber ball moving from the ball chamber seat when the valve is sufficiently inverted to permit passage of product through the ball chamber passage into the ball chamber, through the ball chamber bypass opening, through the product passage into the valve body and out the passage means when the valve is opened;wherein the ball chamber plane is inclined relative the valve body longitudinal axis at an angle of between from about 5.degree. to about 85.degree. and, an opening of the upper end of the product passage of the appendage and an opening of the ball chamber of the appendage, remote from the ball chamber bypass opening, are coplanar with one another and are both received within the socket.
