Analytical specimen cup with testing means
First Claim
1. An analytical specimen cup for testing fluid specimen contained therein, said cup comprising a container wall enclosing said fluid specimen in a container cavity defined by said container wall, an area of said container wall including normally fluid-impervious outer and inner partitions forming a test space therebetween, said inner partition being between said container cavity and said test space and said outer partition being between said test space and outside atmosphere, said container further including a testing-strip means mounted in said test space for contacting said fluid specimen in said test space and changing its appearance in response thereto so as to provide a visual indication of a characteristic of said fluid specimen, said outer partition being at least partially transparent so that said test strip can be viewed from outside atmosphere therethrough, said inner partition including a selectively-operated valve means for being initially closed but being selectively opened from outside atmosphere to allow fluid specimen to enter said test space from said container cavity while not allowing said fluid specimen to escape from said container cavity to outside atmosphere;
- whereby a fluid specimen can be placed into said container cavity without contacting said test-strip means, but can be allowed access to contact said test-strip means by a person in outside atmosphere for activating said test-strip means to provide an indication of a characteristic of said fluid specimen to said person in outside atmosphere without allowing said fluid sample to escape to outside atmosphere.

Abstract
An analytical specimen cup (10) has outer and inner partitions (26, 34) in a lid (14) thereof, with the outer partition being flexible and transparent and the inner partition having a valve (46) comprised of a frangible portion (50) of the inner partition. A chemical test strip (24) is mounted in a test space (42) between the outer and inner partitions and a fluid specimen in the cup can be introduced to the chemical test strip in the test space by manipulating the frangible valve (46) to break it open via the flexible outer partition. The inner partition is formed as a one-piece lid main member (22) with most of the rest of the lid whereas the outer partition is mounted to cover an indentation (30) into a top surface of the lid main member to define the test space in the indentation.
