MATTHEWS V. CHAMBERS. 877 �of its neck suitably formed to receive it, of a stopper con- structed to operate in closing and unclosing the bottle, sub- stantially as described; secondly, I claim so constructing the valve, c, and the mouth of the bottle, that the former may be readily forced through the latter in one direction, and incapable of easy passage throngh it in the opposite direc- tion, as hereinbefore described, for the purpose set forth; thirdly, I claim making the entire stopper of such a length that it cannot tum over in the body of the bottle, as and for the purpose set forth." �The bottles manuf actured by the defendants are designated in the evidence as the "Christin bottle" and the "Kelly bot- tle." The Christin bottle has a loose internai tapered wooden-plug stopper, whitfli is of smaller diameter than the interior of the neck of the bottlej aiai will pass freely in and ont of it.

It is readily inserted through the mouth of the bottle before the rubber ring is put in, but the lower part of the neck of the bottle is 80 constructed that the plug cannot pass down into the bot- tle. The glass plug falls into its rubber seat when the bottle is inverted, and is tightly held there by the Upward action of the gas in the liquid below. The bottle is opened by press- ing the plug downward. �The construction of the plaintiff's patents was brought in ��� �
