Abstract
A self-closing tilting valve sealingly insertable in a lid for a container fillable with product under excess pressure and provided with a valve mounting, comprises a mandrel having a base part and a tip part, and an enveloping nozzle surrounding the mandrel and having an axial product passage receiving the mandrel therein, a head part with an outlet opening for the axial passageway, a foot part having a bottom opening for the axial passageway, and an intermediate portion extending axially between the head part and the foot part, and being substantially rigid. The mandrel top part bears a conically tapered sidewall of axially outwardly increasing diameter, and the head part of the nozzle has an outer end wall about the outlet opening correspondingly tapered to sealingly contact the top part sidewall in closed position. The intermediate portion of the nozzle between the head part and the foot part must be substantially rigid. The mandrel projects downwardly out of the foot part of the nozzle and has a base part thereof extending radially outwardly beneath the underside of the nozzle foot part. Distancing noses are provided at the lower end of the conically tapered sidewalls, which distancing noses cause a gap to be formed between these sidewalls when the mandrel is drawn downwardly axially into the axial passage during opening of the valve by tilting.
