| 摘要 |
Polymeric plumbing fixtures such as sinks, lavatories and tubs are disclosed that comprise a thermoformed or molded interior shell having a top side with a relatively smooth, polymeric surface; a polymeric reinforcing layer bonded to the underside of the shell; and a thermoformed or polymeric cap nestably engageable with the underside of the reinforced shell. The cap cooperates with the shell to encapsulate the reinforcing layer and the reinforcing layer bonds the cap the shell to form a unitary structure. The polymeric cap thereby provides an attractive, finished surface on the underside of the resultant fixture. The structural configuration disclosed herein is particularly preferred for use in making kitchen sinks. A method for making the subject fixtures is also disclosed.
