<p>A bottle lid assembly is disposed at a mouth of a bottle that stores a carbonated liquid therein, to allow the carbonated liquid to exit out of the bottle. Such bottle lid assembly includes a resilient layer that causes a change in internal pressure of the bottle by being compressed and deformed, a lid member having a discharge pipe formed at a side, a suction pipe supported on the lid member and inserted into the bottle and dipped in the carbonated liquid, and a valve tube that connects the suction pipe and the discharge pipe of the lid member, for opening and closing the suction pipe by being raised and lowered by the deformation of the resilient layer and thus entering and exiting with respect to a leading end of the suction pipe. The resilient layer is resiliently deformed by the compression, causing a change in the internal pressure of the bottle, so that the carbonated liquid is exit out of the bottle sequentially through the suction pipe, the valve tube and the discharge pipe with a minimum loss of carbon dioxide.</p> |
