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.

Claims

1. A vial cap coupling device for flexibly coupling together a vial having a mouth and its sealing cap, comprising:

(a) a cylindrical retainer having an inner surface which forms a cavity for snugly receiving the sealing cap and engaging an outer surface of the cap;

wherein the retainer further includes a larger flange which extends inwardly from a top margin of the retainer inner surface to have 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 fully received sealing cap in the cavity to retain the cap therein;

(b) a slide ring which has an inner diameter which is approximately the same as an outside diameter of a cylindrical portion of the vial so that the slide ring can be slid up to a rim at an upper end of the cylindrical portion and so that the slide ring is rotatable about the cylindrical portion; and

(c) a hinge strap which at its ends is integrally connected to the retainer and the slide ring.

2. The vial cap coupling device of claim 1 wherein the inner diameter of the slide ring is sized closely to the outside diameter of the vial cylindrical portion so that the slide ring can fit snugly enough about the cylindrical portion so that it does not tend to fall down the cylindrical portion.

3. The vial cap coupling device of claim 1 wherein the inner surface of the retainer has a diameter sized such that when the retainer cavity receives a sealing cap which has knurls on its outer surface, the retainer inner surface firmly engages the sealing cap so that the retainer and sealing cap turn as a unit, whereby when the sealing cap is placed over the mouth of the vial, the sealing cap can be maneuvered onto the vial mouth in sealing relation therewith by maneuvering the retainer, and the cap can be maneuvered loose from the mouth by maneuvering the retainer.

4. The vial cap coupling device of claim 3 wherein the inner surface of the retainer has a diameter sized such that when the retainer cavity receives a sealing cap which has threads for screwing the cap onto a vial mouth which also is threaded, the retainer inner surface engages the sealing cap so that when the sealing cap is placed over the threaded mouth of the vial, rotating the retainer in one direction rotates the sealing cap onto the vial threaded mouth to close and seal the vial, and rotating the retainer in an opposite direction causes the sealing cap to be loosed from the threaded mouth.

5. The vial cap coupling device of claim 1 wherein the downward shelf and a top of a fully retained sealing cap and the retainer inner surface define a space for containing a vial label;

and wherein the larger flange defines an opening through which a vial label may be viewed.
