Abstract
In machines for filling bottles, liquid passes into a bottle past filling valve sealing sleeve and air exits through a vent tube; the filling valve retainer carries an annular rubber gasket that seals against the lip of the bottle to prevent leakage as the bottle fills; a centering bell is carried on the filling valve retainer and extends over the neck of the bottle; the sealing gasket is secured in the centering bell and the gasket is removed from the filling valve retainer by the removal from the retainer of the centering bell; the centering bell is held to the filling valve retainer by resilient snap-in means.
Claims33
A bottle filling apparatus comprising;
- a bottle filling valve assembly, a bottle centering bell and a bottle lip sealing gasket;
- said bottle filling valve assembly comprising:
- a retainer element;
- liquid flow passage means communicating through said retainer element;
- a liquid inlet valve in said retainer element flow passage means;
- said flow passage means and said valve being shaped so as to direct liquid passing through and past them into a bottle positioned beneath said flow passage means;
- said bell being located beneath said retainer element and beneath said flow passage means;
- said bell comprising a body having a first opening therethrough, and first side walls defining said first opening;
- said first side walls being shaped such that said bell is able to pass over a bottle placed in said first opening and said first side walls being so positioned and shaped as to direct a bottle whose upper end is in said first opening to be beneath said flow passage means;
- cooperating snap fastening means on said bell and said retainer element for holding said bell beneath said retainer element and for enabling snap-in connection and disconnection of said bell and said retainer element;
- said bottle lip sealing gasket being positioned and adapted for engaging the lip of a bottle whose upper portion is in said bell first opening;
- said gasket being located in said first opening of said bell;
- means in at least one of said bell and said retainer element for supporting said gasket.
