Dispensing head for dispensing a product and pressurized dispensing unit equipped with this head

A dispensing head for dispensing a product under pressure, comprising;

• a dispensing member mountable on a pump or valve surmounting a reservoir containing the product and defining an outlet duct for the product, the outlet duct opening to at least one dispensing orifice;
• a substantially rigid actuating fitting movable in response to a pressure exerted on the actuating fitting from a first position to a second position, the actuating fitting being configured to come into engagement with the dispensing member during the movement of the actuating fitting from the first position to the second position in order to move the dispensing member from a closed position to a dispensing position in which the outlet duct is in communication with the reservoir;
• and
• a shut-off device movable with the actuating fitting from the first position in which the dispensing orifice is closed thereby to a second position in which the dispensing orifice is uncovered to allow the product to exit under pressure, wherein said shut-off device is constructed to elastically return to the first position when the actuating pressure ceases, wherein the shut-off device provides sealing between the dispensing member and the actuating fitting.

A unit for packaging a product under pressure, comprising:

• a reservoir for a liquid product to be dispensed and fitted with a valve or a pump;
• a dispensing member mountable on the pump or valve and defining an outlet duct for the product, the outlet duct opening to at least one dispensing orifice;
• a substantially rigid actuating fitting movable in response to a pressure exerted on the actuating fitting from a first position to a second position, the actuating fitting being configured to come into engagement with the dispensing member during the movement of the actuating fitting from the first position to the second position in order to move the dispensing member from a closed position to a dispensing position in which the outlet duct is in communication with the reservoir;
• and
• a shut-off device movable with the actuating fitting from the first position in which the dispensing orifice is closed thereby to a second position in which the dispensing orifice is uncovered to allow the product to exit under pressure, wherein said shut-off device is constructed to elastically return to the first position when the actuating pressure ceases.
