<p>A liquid dispenser (10) comprises: an inner structure (1) that includes a tubular body (2) which can be filled with a liquid (Q) and a double ended needle (71) which is mounted on a distal end of the tubular body (2), has a sharp needle tip on a distal end and a base end of which is capable of communicating with the inside of the tubular body (2); an operation member (5) that has a plunger (51) which carries out a pressing operation for discharging the liquid (Q) from the double ended needle (71) by moving in a direction toward the distal end; a cover member (6) that is capable of moving between a position (A) which covers at least the needle tip of the double ended needle (71) and a position (B) in which the cover member (6) retracts in the base end direction from the position (A) and exposes the needle tip; and a lock mechanism (60) that maintains a deployed state in which the cover member (6) stays at the position (B) until the pressing operation is completed after the cover member (6) moves from the position (A) to the position (B).</p> |
