Abstract

A nozzle that includes a connecting section, a main hollow elongated and conical body, a bell shaped section and an injection bottom is described. The design of the connecting section allows it to be connected to injections machines or to a sealant containing cartridges. The injection button is non-permanently connected to the bell shaped section and it has a circular central protrusion, a series of radially oriented channels ending in circularly positioned openings, which facilitates the direction of the expelled sealant. Alternatively, the button may also include lateral grooves at the walls of the central circular protrusion. The particular design of the injection button allows an efficient and highly accuracy distribution of the sealant on the surfaces and selected parts of machines and artifacts wherein the sealant is applied.

Claims

1. A nozzle for applying sealants from a sealant containing container, such as cartridges, guns or injection machines, said nozzle comprising:

(a) a truncated cone-shaped main elongated body, comprising;

a first end;

a second end;

a truncated cone-shaped internal cavity;

(b) a cylindrical section comprising;

a first end;

a second end, physically connected to the first end of the truncated cone-shaped main elongated body;

a threaded external surface;

an external protruding ring surrounding the second end of said cylindrical section and;

and internal cylindrical cavity in direct and open communication with the truncated cone-shaped internal cavity;

(c) a bell-shaped section, said bell shaped comprising;

a top section, which is physically connected to the second end of said truncated cone shaped elongated body;

a lower section;

bell-shaped internal cavity, which is in open and in straight communication with the truncated cone-shaped internal cavity of said truncated cone-shaped elongated body;

an outwardly projected annular flanged section perpendicularly located around the lower section of said bell-shaped lower section;

(d) a round shape injection button, said injection button comprising;

a disk-shaped round main body, said disk-shaped main body comprising;

a front flat, round surface;

a back flat round surface;

a curved continuous edge projected outwardly in reference to the front surface that surrounds the distal edge in reference to the center of said disk-shaped body;

a hollow cylindrical protrusion centrally projected from the front surface of said disk-shaped main body and;

multiple series of radially positioned channels located across said front and back round surfaces of said disk-shaped main body, said channels ending in openings around the hollow cylindrical protrusion and;

wherein the cylindrical section, the truncated cone-shaped elongated body and the bell-shaped section constitute a single physically connected unit having their respective internal cavities in a continuous and straight forwarding position, thus providing a straight fluid path and wherein by matching or snapping the outwardly projected annular flanged section perpendicularly located around the lower section of said bell-shaped lower section with the curved continuous edge projected outwardly in reference to the front surface of said injection button that surrounds the distal edge in reference to the center of the disk-shaped main body said injection button is coupled in a strong and non-permanent manner to said single unit comprising the cylindrical section, the truncated cone-shaped main body and the bell-shaped section.

2. The nozzle as recited in claim 1, further comprising multiple lateral grooves around the circumference of the hollow cylindrical protrusion of the injection button.

3. The nozzle as recited in claim 1, wherein all its parts are made of plastic.

4. The nozzle as recited in claim 3, wherein the plastic is polypropylene.

5. The nozzle as recited in claim 2, wherein all its parts are made of plastic.

6. The nozzle as recited in claim 5, wherein the plastic is polypropylene.
