This can be achieved by providing an outlet duct and a base body in two separate pieces which can be coupled by different hooking means.

In addition, the hooking portion 550 can block the rotation of the outlet duct 520 relative to the base body.
• the outlet conduit 520 may include an attachment portion 526 for securing the outlet conduit 520 to the finger cot 530.
• the securement portion 526 may be configured to attach to an attachment 532 provided to the finger cot 530.
• the fixing element 532 is a plug projecting from the internal surface of the finger cot 530 extending substantially vertically towards the top of the first section 524 of the outlet duct.
• the attachment portion 526 in Figure 5, is a cylindrical wall projecting from the top of the first section 524 of the outlet duct extending substantially vertically towards the internal surface of the finger cot 530.
• the attachment portion 526 and the element of fixing 532 can be designed to cooperate mechanically and to fix the finger cot 530 to the outlet duct 520 by fitting, gluing, heat sealing, welding.
• the axes of the fixing element 532, of the fixing portion 526, of the first section 524 of the outlet duct, and of the valve of the pressure vessel are coaxial.
• User pressure on the finger cot 530 can cause a substantially vertical movement of the first section 524 of the outlet duct and actuation of the pressure vessel valve.
• the vertical displacement of the first section 524 of the outlet duct is followed by the bending of the deformable sections 525c, 525d of the second section of the outlet duct 520.
• the movable part 525b of the second section can be inclined relative to the first section 524 of the outlet duct. Actuation of the valve will cause the product contained in the pressure vessel to exit through the second end 522 of the outlet duct through passage 523 of the outlet duct.
• the material used for the base body 510 and the material used for the outlet duct 520 may be chosen to be mechanically compatible and / or chemically between them or not.
• the hooking portion 550 is made of a material that can be mechanically and / or chemically compatible with the recycled material of the base body 510 in which the connection hole 540 is made.
• a recycled polymeric material of the base body 510 may be mechanically and / or chemically compatible with a polymeric material of the hooking portion 550.
• the entire base body 510 is made from recycled material.
• both the finger cot 530 and the outer wall 511 of the base body 510 are made from the recycled material.
