A sucking structure attachable to any bottle or container generally available in the market that is incorporated to a bottle by an external straw provided with a sucker to sip water or other potable liquid contained in the bottle; both of said straw and a water inlet hose inside the bottle are connected to a bottle cap and a connector penetrating said bottle cap with its portion exposed above the cap indicating a barb for the straw to press firmly against the connector when the straw is inserted into the connector while the portion of the connector inside the bottle reduces downwardly as its outer diameter becomes larger upwardly to hold it in position when inserted into the bottle cap; and the sucking structure allows the use of any recyclable bottle or container and thus contributes to environmental purpose.
