A pressure-activated self-opening cartridge nozzle (10) having a sharpened circular edge of serrations (18) disposed under the bottom side (36) of the base (32) of the top under the side wall of the nozzle (26) is disclosed for use with a cartridge containing filler material for use with an applicator gun, such cartridge of the type wherein a foil seal (12) is disposed above 5 the filler material in the barrel (28) and beneath the nozzle whereby the foil seal can be punctured by pressurizing the filler material which action causes the foil seal to move into contact with the sharpened circular edge of serrations of the nozzle to puncture the foil seal.
L'invention porte sur une buse de cartouche à ouverture automatique commandée par pression (10), qui présente un bord circulaire effilé à cannelures (18) disposé sous la face inférieure (36 du socle (32) de la partie supérieure au-dessous de la paroi latérale de la buse (26). Cette buse s'utilise avec une cartouche contenant une matière de charge utilisable avec un pistolet applicateur. La cartouche est du type dans lequel un opercule en aluminium (12) est disposé au-dessus de la matière de charge placée dans le canon (28) et sous la buse, si bien que l'opercule en aluminium peut être perforer par pressurisation de la matière de charge, laquelle action amène l'opercule en aluminium au contact du bord circulaire effilé à cannelures de la buse pour perforer l'opercule en aluminium.
