Abstract
A self-triggering inflatable balloon device. In a preferred embodiment, the device comprises a cylinder of compressed gas having an actuating valve thereon. The other end of the actuating valve is coupled to a deflated balloon. The cylinder, valve and deflated balloon are secured to the interior of a box having a lid. An actuating member of the valve is coupled to the box lid such that the valve is opened when the box lid is raised. Upon opening of the box lid, therefore, the actuating valve is opened and the balloon is automatically inflated with the gas from the compressed gas cylinder. The device may be given as a gift wrapped present or mailed to a friend, and will produce a surprise when opened.
Claims8
A valve for a self-triggering inflatable balloon device, comprising:
- a valve casing having an exterior, an interior, and an aperture for coupling a compressed gas container thereto and a nipple for coupling a balloon thereto;
- a spike contained within the valve casing, the spike comprising:
- a head portion adapted to strike a membrane of said gas container and cut a hole into the membrane;
- a shaft portion disposed adjacent the head portion;
- a flute formed into the head portion and adapted to prevent the spike from sealing said hole, the flute being formed by grinding with a grinding wheel;
- and
- biasing means disposed between the spike and an interior surface of the valve casing, wherein the biasing means urges the spike toward the aperture;
- and
- a trigger extending from the exterior to the interior of the valve casing, wherein the trigger limits movement of the spike toward the aperture;
- wherein removal of the trigger from the valve casing enables the biasing means to propel the spike into the aperture, thereby allowing compressed gas within the container to escape into an interior of the balloon, thereby inflating the balloon.
A valve for a self-triggering inflatable balloon device, comprising:
- a valve casing having an exterior, an interior, and an aperture for coupling a compressed gas container thereto and a nipple for coupling a balloon thereto;
- a spike contained within the valve casing, the spike comprising:
- a head portion adapted to strike a membrane of said gas container and cut a hole into the membrane;
- a shaft portion disposed adjacent the head position;
- a flute formed into the head portion and adapted to prevent the spike from sealing said hole;
- said flute being formed by grinding into a pin;
- said pin having a length of about 1.2 inches, a diameter of about 0.094 inches, and a head-end defining about a 45-degree angle with an axis of said pin;
- said grinding wheel having a diameter of about 3 inches and having two grinding surfaces each defining about a 45-degree angle with a plane defined by a circumference of the grinding wheel,
- said flute having bilateral symmetry about a plane including an axis of radial symmetry of said shaft portion;
- and
- biasing means disposed between the spike and an interior surface of the valve casing, wherein the biasing means urges the spike toward the aperture;
- and
- a trigger extending from the exterior to the interior of the valve casing, wherein the trigger limits movement of the spike toward the aperture;
- wherein removal of the trigger from the valve casing enables the biasing means to propel the spike into the aperture, thereby allowing compressed gas within the container to escape into an interior of the balloon, thereby inflating the balloon.
