An inflating valve includes inner and outer pieces
which have first and second peripheral flanges for
cementing together and a central plug and a central
tubular spout to be sealingly fitted together. A
frusto-conical shaped first web portion is formed
between the plug and the first peripheral flange to
project inward from the first peripheral flange and is
provided with a plurality of passage holes for
communication with the tubular spout. A second web
portion of frusto-conical shape is formed between the
tubular spout and the second peripheral flange to abut
against the first peripheral flange and can be flexed
at its wider end so as to separate the tubular spout
from the plug.
Cette invention concerne une valve de gonflage formée d'une partie intérieure et d'une partie extérieure qui comportent un premier et un second rebords périphériques collés de part et d'autre de la paroi d'un objet à gonfler, et un bouchon et une busette tubulaire centrés adaptés pour être réunis de façon étanche. Une première cloison de forme tronconique formée entre le bouchon et le premier rebord périphérique comporte une série de trous de communication avec la busette tubulaire. Une deuxième cloison de forme tronconique formée entre la busette tubulaire et le second rebord périphérique de manière à pouvoir prendre appui contre le premier rebord peut être pliée à son extrémité de grand diamètre pour séparer la busette tubulaire du bouchon.
