Abstract

The dispenser for a liquid to pasty product comprises a container (R) containing the product (P) integral with a rigid outer casing (4) provided in its upper part with a subplate (7) to which there is fixed a hand pump (8) surmounted by a push-button (9). The subplate (7) is in the form of a dish engaged in the container (R) and with its concavity directed towards the face opposite the container. The pump (8) is carried by the base (11) of the dish. The depth (h) of the dish is substantially equal to the length (1) of the pump body. The base (11) of the dish is provided with a movable transition component (13) connected to the base so that it projects in relation thereto, the pump body being engaged in the said component and fixed to the transition component (13) at or below the upper level of the subplate.
