Method for the re-filling of a travel dispenser with product and travel dispenser

A travel dispenser comprising:

• two assemblies which are connected together mechanically for dispensing product in dispensing mode:
• a first assembly including a bottle containing product, a venting passage which is able to be opened in order to connect the interior and the exterior of the bottle and a pump mounted on the bottle which is able to assume, on the one hand, an upper rest position in which the venting passage is closed and, on the other hand, a lower position in which the venting passage is open, the upper and lower positions being considered when the pump is arranged in the upper part of the bottle,
• a second assembly including a device for dispensing product to the outside of the dispenser,
• wherein the travel dispenser further comprises:
• a first mechanism for blocking the pump which is able to be actuated by means of an external action of a user when the pump is actuated in the lower position,
• a second mechanism which is configured in order, by means of an external action of a user, to displace the two assemblies with respect to one another from a first position, in which the two assemblies are axially connected, to a second position in which the two assemblies are able to be moved axially apart from one another.
