NOZZLE STRUCTURE AND ASSEMBLY COMPRISING THE SAME Filed Dec. 9. 1966 INVENTOR! EDGAR R. RQWE I y qzlmy Bar? ATTORNEYS.
United States Patent 3,487,982 NOZZLE STRUCTURE AND ASSEMBLY COMPRISING THE SAME Edgar R. Rowe, Cleveland, Ohio, assignor to The Van Dorn Company, Cleveland, Ohio, a corporation of Ohio Filed Dec. 9, 1966, Ser. No. 600,416 Int. Cl. B65d 5/72, 25/40, 35/38 US. Cl. 222-569 4 Claims ABSTRACT OF THE DISCLOSURE This invention relates to the art of fluid material ap plicators and more particularly to a nozzle structure and assembly comprising the same.
The invention is particularly applicable to conjoint use with a caulking-type cartridge, and it will be described with particular reference thereto; however, it will be ap preciated that the invention has broader applications and may be used in various other assemblies.
Many types of fluid materials, such as putty, lubricating grease, adhesives and sealants are now pre-packaged in disposable caulking-type cartridges. These cartridges generally comprise a hollow, cylindrical tube adapted to be filled with fluid material, fixed front end closure means interconnecting a nozzle structure with the interior of the cylindrical tube, and rear end closure means adapted to move forwardly along the interior surfaces of the cylindrical tube, under the force exerted by a caulking gun piston, or similarly acting device.
The nozzle structure associated with such caulking-type cartridges may be formed from a variety of materials, such as metal, paper and plastic, as well as others having the required structural properies. However, plastics are most generally preferred, and of these, polyethylene is one of the most popular, presumably because of its low cost, good strength and chemical resistance properties, and the ease with which it can be molded.
Whatever the material of construction, the nozzle structure is a thin walled, elongated, relative unprotected appendage, and thus, is susceptible and vulnerable to damage, particularly during handling and shipping. For instance, if a nozzle structure of conventional design is subjected to a head-on impact force, as where the cartridge is dropped nozzle down, there is a tendency for the nozzle structure to become disengaged from its interconnection with the cartridge front end closure means. This drives the nozzle rearwardly into the hollow tube portion, rendering the cartridge useless. The present invention is concerned with alleviating this problem.
In accordance with one aspect of the present invention, there is provided a nozzle structure comprising a gen erally conical shaped hollow body having a forward end terminating in an applicator tip, a rearward end terminating in a radially extending flange, and a base portion just forward of the radially extending flange, adapted to be telescopically engaged by a flange peripheral to an aperture in an end closure means, means on the inner surface of the hollow body, just forward of the base portion, defining an area of reduced diameter.
In accordance with another aspect of the present invention, there is provided, in combination with a cartridge end closure means provided with an aperture having a 3,487,982 Patented Jan. 6. 1970 peripheral flange extending forwardly of the aperture, nozzle means received in, and extending forwardly of the aperture, having a base portion telescopically engaged by the peripheral flange, means on the inner surface of the nozzle means just forward of the base portion, defining an area of reduced diameter, and means coacting with the means defining an area of reduced diameter, forcing a peripheral portion of the outer surface of the nozzle means to expand to a diameter exceeding that of the peripheral flange.
Therefore, an object of the invention is to provide a nozzle structure of improved construction.
Another object of the invention is to provide a nozzle structure capable of resisting a head-on impact force without becoming dislodged from its environment.
Yet another object of the invention is to provide an improved interconnect between a nozzle structure and the end closure means of a caulking-type cartridge.
These and other objects and advantages will become apparent from the following detailed description of a preferred embodiment of the invention when read in connection with the accompanying drawings, in which:
FIGURE 1 is a schematic, pictorial view showing the general arrangement of parts in accordance with a preferred embodiment of the invention;
FIGURE 2 is a schematic, section view with parts exploded, showing a preferred embodiment of the invention; and
FIGURE 3 is a schematic, section view, similar to FIGURE 2, but showing the parts in co-operative relation to each other.
Referring nOW to the drawings within, the showings are for purposes of illustrating preferred embodiments of the invention only, and not for the purpose of limiting the same, FIGURE 1 shows caulking-type cartridge, designated generally as 10, in combination with caulking gun assembly designated generally as 12. The caulking gun assembly comprises socket 14 adapted to receive caulkingtype cartridge 10 for locking engagement therein, which socket is attached to stock 16, provided with trigger 18, and operating rod 20, terminating in piston 22. Actuation of trigger 18 urges operating rod 20 and piston 22 to the left as shown in the drawing.
Caulking-type cartridge 10 comprises hollow cylindrical tube 24, rear end closure means, such as plate 26, adapted to move forwardly along the interior surfaces of cylindrical tube 24, under the force exerted by piston 22, and fixed, front end closure means, such as plate 28, interconnecting nozzle structure, designated generally as 30, with the interior of cylindrical tube 24. Front end closure plate 28 is provided with lip portion 29 adapted to receive and secure the leading edge of hollow cylindrical tube 24 thereto.
Nozzle structure 30 comprises generally conical shaped hollow body 32, having a forward end terminating in applicator tip 34, which may be open as shown in FIGURE 1, or closed as shown in FIGURES 2 and 3, and a rearward end terminating in radially extending flange 36.
Front end closure plate 28 comprises aperture 38, surrounded by peripheral seat 40 adapted to receive radial- 1y extending flange 36 of nozzle structure 30, and peripheral flange 42 adapted to telescopically receive base portion 44 of the nozzle structure.
As seen in FIGURES 2 and 3, the inner surface of conical shaped hollow body 32 is provided with means on the inner surface thereof, just forward of base portion 44, defining an area of reduced diameter, such as inwardly projecting circumferential bead 46. Circumferential bead 46 is positioned just rearwardly of circumferential shoulder 48, adapted to receive the leading edge of wedging means, such as annular ring 50.
Front end closure plate 28, nozzle structure 30, and annular ring 50 are assembled as shown in FIGURE 3. It will be noted that annular ring 50 coacts with circumferential bead 46, to expand the latter, forcing a peripheral portion of the outer surface of hollow body 32 to expand to a diameter exceeding that of peripheral flange 42. The resulting bulge just forward of base portion 44 which is telescopically engaged by peripheral flange 42, prevents the nozzle structure from moving rearwardly under the influence of a head-on impact force. Base portion 44 itself is expanded slightly under the urging of annular ring 50. This results in a tight, sealing engagement between the base portion and peripheral flange 42, which also helps prevent relative movement between nozzle structure 30 and front end closure plate 28. Finally, the seating of radially extending flange 36 in peripheral seat 40 prevents the nozzle structure from moving forwardly of front end closure plate 28. Thus, the arrangement shown effectively locks nozzle structure 30 into its interconnection with front end closure plate 28.
The present invention has been described in conjunction with certain structural embodiments; however, it is to be appreciated that various structural changes may be made in the illustrated embodiments without departing from the intended scope and spirit of the present invention as defined in the appended claims.
Having thus described my invention, I claim:
1. A nozzle structure comprising a generally conical shaped hollow body having a forward end terminating in an applicator tip, a rearward end terminating in a radially extending flange, a base portion just forward of said radially extending flange adapted to be engaged by a flange peripheral to an aperture in end closure means, a first inwardly projecting circumferential bead on the inner surface of said body just forward of said base portion, and a second inwardly projecting circumferential head on the inner surface of said body forward of said first inwardly projecting circumferential bead, said first and second inwardly projecting circumferential beads being operative to receive the leading edge of wedging means adapted to urge said base portion into sealing engagement with said peripheral flange.
2. The nozzle structure as defined in claim 1 wherein at least one of said beads is continuous.
3.
