Universal cartridge nozzle and kit

Abstract

A universal cartridge nozzle and corresponding kit are provided. The nozzle has a longitudinal hollow conical body for dispensing sealant provided by a sealant cartridge. The body is sectionable along its length, and has a mounting end for mounting to the supply tube of a sealant cartridge. The body also has a circumferential groove extending inwardly into and about the body at the mounting end. The groove defines an outer groove wall and an inner groove wall, and is adapted to receive the mounting flange of a cartridge gun therein so as to secure the body to the cartridge. The body also has a circumferential sealing member extending into a hollow interior of the body from the inner groove wall at the mounting end. The sealing member sealingly engages the supply tube upon the supply tube being inserted into the body. The sealant is dispensed from the nozzle via a dispensing end.

1 . A universal cartridge nozzle for installation on different models of a sealant cartridge of the type adapted to be loaded into a cartridge gun having a circumferential mounting flange, the sealant cartridge having an end face and a supply tube projecting therefrom, the nozzle comprising: a longitudinal hollow conical body for dispensing sealant provided by the supply tube of the sealant cartridge, the body being sectionable along its length and having a mounting end being removably mountable to the supply tube of the sealant cartridge and secured thereto by the cartridge gun; a circumferential groove extending inwardly into and about the body at the mounting end and defining an outer groove wall and an inner groove wall, the groove adapted to receive the mounting flange of the cartridge gun therein so as to secure the mounting end of the body between the end face of the sealant cartridge and the mounting flange of the cartridge gun; a circumferential sealing member extending into a hollow interior of the body from the inner groove wall at the mounting end, the sealing member adapted to sealingly engage the supply tube upon the supply tube being inserted into the body; and a dispensing end adapted to convey the sealant from the body. 
     
     
         2 . The nozzle of  claim 1 , wherein the mounting end extends between a circumferential cartridge flange for mating with the end face of the sealant cartridge and a circumferential second face spaced apart from the cartridge flange in a direction of flow of the sealant. 
     
     
         3 . The nozzle of  claim 2 , wherein the second face has a second face diameter being less than a cartridge flange diameter of the cartridge flange. 
     
     
         4 . The nozzle of  claim 2 , wherein the sealing member extends radially into the hollow interior of the body from a point on the inner groove wall between the cartridge flange and the second face. 
     
     
         5 . The nozzle of  claim 2 , wherein the sealing member extends radially into the hollow interior of the body from a point on the inner groove wall adjacent to the cartridge flange. 
     
     
         6 . The nozzle of  claim 2 , wherein the sealing member extends radially into the hollow interior of the body from a point on the inner groove wall adjacent to the second face. 
     
     
         7 . The nozzle of  claim 1 , wherein the sealing member extends into the hollow interior along a curve, the curve opening toward a direction opposite a flow of the sealant. 
     
     
         8 . The nozzle of  claim 1 , wherein the sealing member extends into the hollow interior at an angle to a direction of a flow of the sealant. 
     
     
         9 . The nozzle of  claim 1 , wherein the groove has a groove width exceeding a corresponding thickness of the mounting flange of the cartridge gun. 
     
     
         10 . The nozzle of  claim 1 , wherein the inner groove wall has a groove wall diameter being substantially equal to or greater than a tube diameter of the supply tube. 
     
     
         11 . The nozzle of  claim 1 , wherein the body further includes at least one diameter marking disposed at a point on a length of the body, the at least one diameter marking being indicative of a diameter of a cross-section of the body at said point. 
     
     
         12 . The nozzle of  claim 1 , wherein the sealing member is made of a resilient material. 
     
     
         13 . The nozzle of  claim 1 , wherein the sealing member is made of the same material as the supply tube of the sealant cartridge. 
     
     
         14 . A sealant kit, comprising:
 a cartridge gun having a circumferential mounting flange;   a sealant cartridge having an end face and a supply tube projecting away therefrom, the sealant cartridge being mountable to the cartridge gun and securable thereto via the mounting flange; and   a universal cartridge nozzle for installation on different models of the sealant cartridge, the nozzle comprising: a hollow conical body for dispensing sealant provided by the supply tube of the sealant cartridge, the body being sectionable along its length and having a mounting end being removably mountable to the supply tube of the sealant cartridge; a circumferential groove extending inwardly into and about the body at the mounting end and defining an outer groove wall and an inner groove wall, the groove adapted to receive the mounting flange of the cartridge gun therein so as to secure the mounting end of the body between the end face of the sealant cartridge and the mounting flange of the cartridge gun; a circumferential sealing member extending into a hollow interior of the body from the inner groove wall at the mounting end, the sealing member adapted to sealingly engage the supply tube upon the supply tube being inserted into the body; and a dispensing end adapted to convey the sealant from the body.
