Abstract

ABSTRACT OF THE DISCLOSURE
A polyethylene cap, for use with containers, particu-larly polypropylene containers for containing medical speci-mens in preservative fluid such as formaldehyde, is provided with a 3-face seal, wherein a rim portion of the container is trapped in sealing, contacting relation on three mutually adjoining faces, whereby any tendency of the container rim to "relax" out of sealing engagement with a contacting face por-tion of the cap is effectively precluded by the geometry of the cap seal. In the case of polypropylene, which is suscept-ible to such "relaxation", the subject cap enables the effect-ive sealing of polypropylene containers so that advantage may be taken of the superior properties of polypropylene in non-reactive, secure containment of possibly contaminated medical specimens in liquids such as formaldehyde, a known carcinogen.
In a preferred embodiment the cap has a "feel" element, to give actual indication of engagement.
