Description

technical field

[0001]

[01] The present invention relates to rings for aerosol dispensing valves. Background technique

[0002]

[02] It is known to use rings in conjunction with aerosol dispensing valves, in particular dosing valves mounted on a reservoir containing the product to be dispensed. These rings are used in particular in valves which can be used in an inverted position, ie the valve is located below the reservoir when a dose of product is expelled. These rings generally have two main functions, namely, on the one hand, to ensure the maximum quantity of product contained in the dispensing reservoir, and at the same time to limit the dead volume below the valve inlet when the valve is in the inverted use position. On the other hand, the ring also serves to limit the contact of the product with the neck gasket, which is generally located between the neck of the reservoir and the retaining ring or cap used to secure the valve to the container. By limiting the contac...
