Embodiment Construction

[0024] will indiscriminately refer to Figure 1 to 4. Describe in detail the components, assembly methods and advantages of a dispensing head implemented according to a non-limiting embodiment of the present invention.

[0025] The dispensing head has two basic components, the dispensing head body 1 and the spray nozzle 4 . These two components can be realized by injection molding of plastic material. The dispensing head body 1 is preferably implemented in one piece: it can however be implemented from several components assembled with each other. The same is true for the injection nozzle 4 , which is preferably embodied in one piece.

[0026] The dispenser head body 1 has a substantially cylindrical peripheral skirt 11 which is closed at the upper end by a deck 12 . The dispenser head body 1 also has a connection sleeve 13 , which here extends concentrically within the peripheral skirt 11 . A connecting sleeve 13 extends downward from the table 12 . The connecting casing ...

Abstract

Fluid product dispensing device with a pre-compression pump (6) and a dispensing head (T), - the pre-compression pump has a pre-compression spring (69) for increasing the pressure in the pump chamber (60) and a reciprocating actuator Rod (65), - dispensing head (T) with input well (14) for connection with actuating rod (65) and injection nozzle (4) for forming spray through dispensing hole (43), The spray nozzle is mounted in the mounting housing (2), characterized in that: - the preload spring (69) has a stiffness of less than about 3 N / mm, for example about 1 N / mm to 3 N / mm, and - at least two Supply pipes (15) each connect the input well (14) to the mounting socket (2).

Description

technical field [0001] The present invention relates to a fluid dispensing device for connection to a fluid reservoir to form a fluid dispenser. This dispensing device has a preload pump and a dispensing head, which is connected to the pump in order to be able to actuate the pump. The designs involved here are very common in the fields of cosmetics, beauty products or medicine. Background technique [0002] Typically, preloaded pumps have an actuating lever that reciprocates in the pump body against a return spring. A piston is mounted on the actuating rod, the movement of which by the actuating rod allows changing the volume of the pump chamber, thereby putting the fluid contained in the pump chamber under pressure. The preload pump also has a preload spring which acts on the piston to increase the pressure in the pump chamber during the compression phase of the pump chamber. The design of the preload pump involved here is very common. [0003] On the other hand, the di...
