Abstract
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shaped sections wipe off excess fluid from the outside of the needle and then close when the needle is completely withdrawn, thus retaining the fluid within the device.
Claims15
An anti-spill, fluid filling port that accepts a fluid filling needle for transferring fluid into a fluid holding device, the fluid filling port comprising:
- an upper section that maintains contact with the fluid holding device;
- and
- a sloping section, coupled to the upper section, the sloping section comprising:
- a plurality of movable sections, each section being adjacent to two other sections and having a hinge side coupled to the upper section, the hinge side being the higher point of the sloping section;
- and
- an apex where the plurality of sections meet substantially simultaneously at the lowest point of the sloping section, wherein the upper section comprises a retaining device for holding in a plug against the sloping section.
An anti-spill, ink filling port that accepts an ink filling needle and is molded into an inner liner of an ink dispensing device, the ink filling port comprising:
- a cylindrical upper section;
- and
- a bottom, sloping section, coupled to the upper section, the bottom, sloping section comprising:
- a plurality of movable sections, each section being adjacent between two other sections of the plurality of movable sections and having a wider, hinge side coupled to the upper section, the hinge side being the higher point of the bottom, sloping section;
- and
- an apex where the plurality of movable sections meet substantially simultaneously at the lowest point of the sloping section, wherein a retaining device holds a plug device against the inner surface of the bottom, sloping section such that the ink filling port is sealed.
