Patent ID: 7735690

Claim:
A device for encasing a system for dispensing a liquid product, comprising: an evacuation conduit comprising a downstream element having a downstream end that opens to the outside, the downstream element having a longitudinal axis and a cross-section that is generally perpendicular to the longitudinal axis; a compartment respectively delimited by a back wall and a front wall, said back wall having a generally planar inner surface and said front wall having an outlet orifice formed therein; and at least one elastic return element supported by said system on the side opposite the downstream end that can retract such as to allow said system to be inserted in said compartment and can then rest against the back wall so as to insert and maintain the downstream end of said conduit in said outlet orifice; wherein said elastic return element is made up of at least one flexible tab that has a guiding bottom face, tilted in its relaxed position in relation to the cross-section of the downstream element of said conduit which comes into sliding contact with the back wall when the dispensing system is inserted; and wherein said tab has a generally planar flat end that is generally parallel to the cross-section of the downstream element of said conduit, that comes into stable resting contact with the back wall, and that is generally co-planar with said generally planar inner surface of said back wall, when the downstream end of the conduit is inserted in the outlet orifice, such that forces between the generally planar flat end of said tab and said generally planar inner surface of said back wall force the downstream end of the conduit toward said front wall.
