ChargePoint Technology sell "Dispensing Funnel"

Used within powder-dispensing operations, this funnel accurately fills the transfer bag or container through a ChargePoint valve, with its leg(s) positioned beside the open valve disc so powder is directed around rather than across it, keeping it out of direct contact with the valve during transfer. Typically deployed inside a dispensing isolator, it delivers an especially clean transfer and minimizes dust exposure once the funnel is removed and the valve uncoupled, letting ChargePoint valve designs exceed their normal performance envelope, add a safety margin, or allow the use of simpler valve designs that would otherwise need more advanced systems.
