ABSTRACT:
A solvent-bonded joint between plastic members, and a method of making the same, particularly useful where such members are intended to convey fluids such as sterile medical solutions. The joint includes a pair of members joined at a zone of interference, a tapered crevice between the members, and a solvent bond in the tapered crevice. After the members have been fitted together, the solvent is introduced into the tapered well or crevice leading to the zone of interference to form the permanent solvent bond. The zone of interference serves as a barrier against any liquid or other flowable material entering the tapered crevice in the opposite direction prior to formation of the solvent bond and further serves as a barrier against the escape of solvent through the crevice, or the contamination by solvent of any material or parts beyond or below the crevice.
