ABSTRACT:
A vial cap coupling device for flexibly coupling together a vial and its sealing cap includes a cylindrical retainer having an inner surface which forms a cavity for snugly receiving the sealing cap and firmly engaging an outer surface of the cap, a slide ring which has an inner diameter which is about the same as the outside diameter of the cylindrical portion of the vial so that the slide ring can be slid up the cylindrical portion of the vial to the rim at the upper end of the cylindrical portion, and a hinge which at its ends is integrally connected to the retainer and slide ring. The vial cap coupling device retainer further includes a small resilient flange which has an upward shelf which retains within the cavity a sealing cap by abutting against a bottom of the cap. A larger flange extends inwardly from a top margin of the retainer inner surface to an inner diameter which is smaller than the diameter of the outer surface of the sealing cap, forming a downward shelf which abuts against a contained sealing cap in the cavity to retain the cap therein. A space for a vial label is formed by the downward shelf, the top of the fully retained sealing cap, and the retainer inner surface. The larger flange defines an opening through which the vial label may be viewed.
