A single-use, clamshell protective cap for use primarily in healthcare settings in order to maintain the integrity of a medication solution. The cap has two halves, a cylindrical skirt, a puncture resistant lid portion, an interior flange, and an interlocking snap. When placed around a flanged injection port such as is found on a conventional fluid container and closed, the lid portion covers an access site on an injection port. After the cap is placed, the interior flange engages the port flange to prevent upward axial movement relative to the port, thereby preventing removal of the cap and thus deterring unwanted or erroneous drug administrations or withdrawals.

1. A snap-over clamshell cap for a port having a flange, comprising: a first half comprising a portion of a cylindrical skirt having a base, a unitary circular lid portion adjoined to said cylindrical skirt at an end of said skirt opposite said base, a flange extending inwardly from said base, said flange being essentially parallel to said lid portion, and a first interlocking snap member;a second half comprising a second cylindrical portion of a cylindrical skirt having a base, a second flange extending inwardly from said base, and a second interlocking snap member;a connecting member between said first and second halves opposite said interlocking snap members;wherein the cylindrical portion and flange of the first half engage the cylindrical portion and flange of the second half in a complementary manner when the first and second interlocking snap members are connected;wherein an end of said second cylindrical skirt portion opposite said base is beveled and a circumference of said lid portion not adjoining said first cylindrical skirt portion is beveled; andwherein said beveled end and beveled circumference are complementary such that said beveled end of said second cylindrical skirt portion and said beveled circumference of said lid portion not adjoining said first cylindrical skirt portion are interlocked when said cap is closed about said hinge. 2. The cap of claim 1 wherein said connecting member is a hinge. 3. The cap of claim 1 wherein said flanges engage an injection port so as to prevent axial movement of said cap in a direction away from said port. 4. The cap of claim 1 wherein said cylindrical skirt and said lid portion are substantially rigid. 5. The cap of claim 1 wherein said lid portion is puncture resistant. 6. The cap of claim 1 wherein the diameter of said lid portion is greater than the diameter of an access site on said port. 7. The cap of claim 1 wherein the cap is color coded to denote a specific class of substances. 8. The cap of claim 1 further comprising complementary vertical surfaces adjacent said complementary beveling. 9. The cap of claim 1 wherein the portion of said circular lid portion that corresponds to an access point on a port below is devoid of seams. 10. The cap of claim 1 wherein an interior of said cap is devoid of teeth and ridges for engaging a port. 11. The cap of claim 1 further comprising a rib formed on said second cylindrical skirt portion, said rib extending inwardly to support said lid portion when said first and second interlocking snap members are connected. 12. The cap of claim 11 wherein said rib has a beveled upper surface at an inward leading edge.
