Medical vial cap
A crown, for a medical vial opening, has a top portion and a skirt surrounding the top portion. The skirt terminates at a lower edge defined in a first horizontal plane. An opener assembly is mounted to a portion of the top. A first scoring line extends from the portion of the top to which the opener assembly is mounted to the lower edge of the skirt in a continuous radial direction, and a second scoring line provides an upper radial segment extending from the opener assembly to the skirt along a radial axis, and a lower annular segment that extends circumferentially along the skirt in an annular direction and extending from a terminus of the upper radial segment. The lower annular segment is defined in a second horizontal plane equidistant to the first horizontal plane associated with the lower edge of the skirt.
1. A crown for a medical vial opening, the crown comprising:
a crown top portion having an opening to selectively house a plug; and
a pull tab ring;
a flap hinge on the crown top portion and attached to the pull tab ring;
a plug attached the pull tab ring, the plug comprising a plug top portion, a plug bottom portion, and an annular plug side wall formed by and between the plug top portion and the plug bottom portion; and
an exterior annular receiving groove around the plug side wall, the exterior annular side wall groove being sized such that the pull tab ring fits snugly into the groove to attach the plug to the pull tab ring,
so that when the pull tab ring is pulled upward, the plug is released from the crown top portion opening, pivoting on the flap hinge to selectively open the opening of the crown top portion.
2. The crown of claim 1 , wherein the pull tab ring is substantially flush with a top height of the crown.
3. The crown of claim 2 , further comprising a recess formed on an edge of the crown top portion and configured for fingernail access by a user of the pull tab ring.
4. The crown of claim 2 , wherein the plug and corresponding crown top portion opening are centered in the top portion.
5. The crown of claim 2 , wherein the plug is disk shaped.
6. The crown of claim 2 , wherein a portion of the plug is received within the crown top portion opening.
