Easy-open lid assembly for a bottle

An easy-open lid assembly for a bottle, the lid assembly comprising:

• a body adapted to be connected to the bottle and having a socket centrally defined in the body, a slot defined in a side of the body with at least one guiding slot defined in a periphery defining the slot, a key-way defined in a boundary portion of a top surface of the body to communicate with the slot;
• a cap detachably disposed on the socket with a top opening defined in the cap;
• a nipple received in the socket and the nipple having a configuration to be able to extend through the top opening, the nipple having an annular protrusion formed on the nipple to abut the socket and prevent escape of the nipple from the socket;
• a lid hinged to the body and the lid having a flange formed on an edge of the lid;
• a straw connected to the nipple and extendable into the bottle;
• a first spring disposed around the straw and sandwiched between the annular protrusion and a bottom surface defining the socket to provide an upward resilience to the nipple;
• a pushbutton with a configuration to be received in the slot of the body, the pushbutton having a hook to mate the flange of the lid and at least one resilient barb corresponding to the guiding slot, whereby the pushbutton is received in slot with the at least one barb received in the at least one guiding slot and the hook slidingly received in the sliding slot;
• and
• a second spring disposed in the slot of the body and sandwiched between the pushbutton and the body to provide an outward resilience to the pushbutton;
• whereby the lid is closed and maintain closed due to engagement of the hook and the flange, and the lid is opened by pushing the pushbutton to release the flange from the hook such that the nipple is pushed outwardly from the socket by the first spring.
