What is claimed is: 1. A package (1), comprising: a pressure deformable container (2) for containing a product; and a dispensing head (3) adapted to be ruptured for dispensing of the contained product, wherein, the dispensing head (3) comprises i) a neck (4) formed on the container (2) and delimiting an orifice, and ii) a nozzle (5) comprising a skirt (6), the nozzle (5) and the neck (4) each comprise a bearing surface, the nozzle (5) is mounted on the neck (4) with the bearing surface of the neck (4) contacting the bearing surface of the nozzle (5), and a weld (11) welding the skirt (6) to the neck (4) at said bearing surfaces, wherein the bearing surface of the neck (4) is its distal end and the bearing surface of the nozzle (5) is a flange (17) on the nozzle (5), the flange (17) is formed on an external wall of the skirt (6), and an internal reservation (15) between the contact zone of the bearing surfaces of the neck (4) and the nozzle (5) and a packaging region for the product in the container (2) and delimited by the walls of the skirt (6) and of the neck (4). 2. The package (1) according to claim 1, wherein the nozzle (5) comprises a guide surface coacting with a wall of the neck (4) for mounting the nozzle (5). 3. The package (1) according to claim 1, wherein the internal reservation (15) is separated from the packaging zone for the product in the container by an incline (16) on the wall of the neck (4). 4. The package (1) according to claim 1, wherein the nozzle (5) comprises a peripheral portion (14) covering the distal end of the neck (4). 5. The package (1) according to claim 1, wherein the neck (4) comprises a rigidification zone (13). 6. The package (1) according to claim 1, wherein the nozzle (5) comprises a central portion (8) traversed by a flow channel (9). 7. The package (1) according to claim 6, wherein the nozzle (5) comprises an end zone (10) adapted to be ruptured to free the flow channel (9). 8. The package (1) according to claim 6, wherein said central portion (8) coacts with the internal wall of the neck (4). 9. Process for the production of a package (1), comprising the steps of: forming a container (2) with a neck (4) delimiting an orifice; forming a nozzle (5) with a skirt (6); mounting the nozzle (5) on the neck (4) and bringing into contact a bearing surface of the neck (4) with a bearing surface of the nozzle (5); welding the skirt (6) on the neck (4) at said bearing surfaces, wherein the neck and nozzle form a dispensing head (3) adapted to be ruptured for dispensing product contained in the container, forming the bearing surface of the neck (4) by its distal end and the bearing surface of the nozzle (5) by a flange (17) on the nozzle (5); forming the flange (17) on the external wall of the skirt (6); and forming an internal reservation (15) between the contact zone of the bearing surfaces of the neck (4) and the nozzle (5) and a packaging region for the product in the container (2) and delimited by the walls of the skirt (6) and of the neck (4). 10. The process according to claim 9, wherein the container (2) is filled through the neck (4) before assembling the nozzle (5). 11.
