Abstract
A packaging installation having at least one filler station includes a filler spout and a connection member connected firstly to a feed duct and secondly to a purge duct in order to connect these ducts to the spout. The connection member includes a spout supply pipe connected to the feed duct and a return pipe opening out into the spout and connected to the purge duct. The supply pipe and the return pipe are entirely independent of each other, such that the connection member acts continuously to connect in series the feed duct, the supply pipe, the spout, the return pipe, and the purge duct.

An installation for packaging a substance in containers, the installation including:
- at least one filler station comprising a filler spout having a spout body with a bottom end provided with an orifice fitted with a controlled delivery valve;
- and
- a multichannel connection member connected firstly to a feed duct and secondly to a purge duct for connecting these ducts to the spout, the multichannel connection member comprising for this purpose both a filler spout supply pipe opening out into the spout body above the delivery valve and connected to the feed duct, and also a return pipe opening out into the spout body above the delivery valve and connected to the purge duct, the supply pipe and the return pipe being entirely independent of each other, such that the multichannel connection member acts continuously to connect in series the feed duct, the supply pipe, the filler spout, the return pipe, and the purge duct.
An installation for packaging a substance in a plurality of containers, the installation comprising:
- a plurality of filler stations each comprising a filler spout having a spout body with a bottom end provided with an orifice fitted with a controlled delivery valve;
- and
- a multichannel connection member connected firstly to a feed duct and secondly to a purge duct for connecting these ducts to the filler spouts, the multichannel connection member comprising:
- a filler spout supply pipe opening out into the spout body above the delivery valve and connected to the feed duct;
- and
- a return pipe opening out into the spout body above the delivery valve and connected to the purge duct, the supply pipe and the return pipe being entirely independent of each other, such that the multichannel connection member acts continuously to connect in series the feed duct, the supply pipe, the filler spouts, the return pipe, and the purge duct.
