<p>A pump having a sealing mechanism. The pump comprises: (a) a main body (1) having a first surface (11), (b) an attachment body (3) with first attachment means to a bottle neck, (c) an inlet valve (9), (d) a second surface (13) where both surfaces (11, 13) define a pumping chamber (17), and (e) a discharge valve (43), where both surfaces (11, 13) are adapted to perform a relative movement therebetween causing the pumping of a liquid. The attachment body (3) is connected to the main body (1) with possibility of a relative displacement between an open position and a closed position and comprises a projection which, when the attachment body (3) and the main body (1) are in the closed position, prevents the second surface (13) from performing the relative movement.</p> |
