Abstract
The mixing of materials pre-packaged in precise amounts in separate vials. Use is made of an adaptor of resilient material in which a pair of vials are releasably engaged in sealing relation, in end-to-end relation, with a communicating passage therebetween. The assembled adaptor and vials can be shaken to effect the desired intermixing of the materials present in the vials without loss of material or contamination. Thereafter the mixture can be located in one vial and the adaptor separated from the vials for re-use.
Claims3
For use in intermixing flowable content material from separate vials having a body portion, a neck portion of smaller internal diameter than the body portion to provide an access opening of lesser diameter than the interior of the vial, and a lip portion on the end of the neck portion of larger diameter than the neck portion, with an access opening extending through the lip and neck portion into the body portion, an adaptor of rigid resilient material having a passage extending continuously therethrough including a pair of axially spaced grooves shaped to correspond to the outer contour of the lip portion of the vials and having an inner wall-to-wall diameter within the range of slightly less than to up to the outer wall-to-wall diameter of the outer lip portion of the vials, expandable portions beyond the grooves at the ends of the passage having a diameter within the range of slightly less than to up to the outer wall-to-wall diameter of the neck portion of the vials and a length no greater than the length of the neck portion of the vials, while the portion between the grooves has a length dimensioned to space the grooves one from the other and a diameter corresponding to the diameter of the access opening of the vials to provide for a continuous passage of uniform dimension between the access openings of the vials when in the adaptor.
