PUMP COMPRISING CLOSURE MECHANISM

摘要

The invention relates to a pump comprising a closure mechanism.The inventive pump comprises: [a] a main body (1) having a first surface (11); [b] a fixing body (3) which is equipped with first fixing means for fixing same to the neck of a bottle; [c] an inlet valve (9); [d] a second surface (13) which, together with the first surface (11), defines a pumping chamber (17); and [e] an outlet valve (43), whereby said two surfaces (11, 13) can move in relation to one another and, in this way, generate the pumping of the liquid. According to the invention, the fixing body (3) is joined to the main body (1) such that the two can move in relation to one another between an open position and a closed position. In addition, said fixing body is equipped with a flange which prevents the second surface (13) moving in relation to the first when the fixing body (3) and the main body (1) are in the closed position.
