ANTI-SPILL FLUID FILLING PORT

摘要

The anti-spill, fluid filling port has an upper section that is molded into the soft plastic wall of the fluid holding device. The bottom of the upper section is capped with a semi-spherical section that comes to an apex in the middle. The semi-spherical section is formed by six triangular-shaped sections that meet at the apex. As the fluid filling needle is inserted into the port, the triangular shaped sections separate wide enough to allow the circumference of the needle to be inserted but remain in contact with the needle. As the fluid filling needle is removed, the triangular shaped sections wipe off excess fluid from the outside of the needle and then close when the needle is completely withdrawn, thus retaining the fluid within the device.
