Abstract
A fixing method and device for fixing a metering member (3) including a cylindrical body (4) in a receptacle (1) including a cylindrical neck (2). The receptacle contains a substance to be dispensed. The outside diameter of the body of the metering member is slightly smaller than the inside diameter of the neck of the receptacle, and the body of the metering member is held securely in the neck by a cylindrical ferrule (6) whose outside diameter is slightly greater than the inside diameter of the body of the metering member, the ferrule being engaged as a force-fit inside the body of the metering member at the neck of the receptacle.
Claims11
A mounting arrangement for fixing a metering member (3) in a receptacle (1), said arrangement comprising:
- a) a receptacle having a cylindrical neck (2) and containing a substance to be dispensed,
- b) a metering member having a cylindrical body (4) with a top portion terminated by a flange (5), the metering member body having an outside diameter slightly smaller than an inside diameter of said cylindrical neck of the receptacle and abutting a top end of said neck via said flange, and
- c) a cylindrical ferrule (6) having an outside diameter slightly greater than an inside diameter of the metering member body over at least a portion of the ferrule length, said ferrule being engaged by force in the metering member body at the neck of the receptacle.
A method of fixing a metering member (3) comprising a cylindrical body (4) having a top portion terminated by a flange (5) in a cylindrical neck (2) of a receptacle (1) containing a substance to be dispensed, an outside diameter of said body of the metering member being slightly smaller than an inside diameter of said neck of the receptacle, said method comprising the following steps:
- a) inserting the body of the metering member in the neck of the receptacle until said flange of the body of the metering member comes into abutment against a top end of said neck of the receptacle, said body of the metering member not being tight in said neck of the receptacle;
- and
- b) force fitting a cylindrical ferrule (6) in the body of the metering member, an outside diameter of said ferrule being slightly greater than an inside diameter of said body of the metering member over at least a portion of the ferrule length so as to expand said body of the metering member such that it becomes tight in the neck of the receptacle.
