PLASTIC NOZZLE MOUNTING AND METHOD OF FORMING SAME Filed April 22, 1955 2 Sheets-Sheet 2 INVENTOR h z zzz ami'fiun Ze ATTORNEYS United States Patent PLASTIC NOZZLE MOUNTING AND METHOD OF FORMING SAME William F. Punte, Chicago, 11]., assignor to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application April 22, 1955, Serial No. 503,078

7 Claims. (Cl. 222-566) The invention relates generally to metallic receptacles and primarily seeks to provide a novel plastic nozzle mounting on a metal can top or breast wherein provision is made for efiiciently sealing the union between the nozzle and its metal support, without danger of the nozzle turning in its mounting when screw cap closures are applied thereon, and also for preventing presentation of raw metal body or edge portions either internally or externally of the mounting.

An object of the invention is to provide a nozzle mounting of the character stated wherein the container breast has an upstanding neck in which the tubular plastic nozzle is inserted and through which it projects, said neck being connected with the breast through a well rounded curve firmly abutted and covered by a flange projection at the lower end of the nozzle, the upper end extremity of the neck having an inwardly turned edge embedded in the outer surface of the nozzle body, and said neck also being provided with an inwardly directed bead embedded in the nozzle body and securing the same against endwise movement in the neck.

Another object of the invention is to provide a nozzle mounting of the character stated wherein is included means on the neck for indenting the nozzle body at spaced intervals thereabout for securing the nozzle against rotation in the neck.

Another object of the invention is to provide a novel method of forming a nozzle mounting of the character stated wherein the nozzle is forced into and through the mounting neck to cause the nozzle flange to press firmly against and provide a protective covering over the juncture of the neck and the breast, and the inwardly turned edge extremity of the neck to be embedded in the external surface of the nozzle, followed by a beading of the neck into the nozzle to prevent endwise movement of the nozzle in the neck.

A further object of the invention is to provide a novel method of the character stated wherein is included the step of providing indents spaced about the neck and extending into the nozzle to prevent rotation of the nozzle in the neck.

A still further object of the invention is to provide a novel method of the character stated wherein the nozzle rotation preventing indentation is provided in the beading and simultaneously with said beading.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawing.

In the drawing:

'Figure 1 is a fragmentary vertical cross section through the top portion of a can structure embodying the invention.

Figure 2 is an enlarged fragmentary vertical cross section illustrating the nozzle mounting neck on the breast, a nozzle being shown in the process of being inserted therethrough, and said nozzle being shown partly in section and partly in side elevation.

Figure 3 is an enlarged fragmentary sectional view showing the upper edge extremity of the neck embedded in the nozzle prior to the beading of said neck.

Figure 4 is a view similar to Figure 3 showing the beading and indenting of the neck in process.

Figure 5 is an enlarged horizontal section on line 5-5 of Figure 1 taken across the nozzle mounting at the position of the neck bead and showing the circumferentially spaced indents.

Figure 6 is an enlarged fragmentary sectional view illustrating a completed nozzle mounting of a slightly modified form wherein the inturned neck edge is serrated to provide means for preventing rotation of the nozzle in the neck, in substitution for the indents in the neck bead.

Figure 7 is a further enlarged horizontal section on line 7-7 of Figure 6 taken at the position of the serrated neck edge and showing engagement of the serrations in the nozzle body effective to prevent rotation of the nozzle relative to the supporting neck.

'In the example of embodiment of the invention herein disclosed, the improved nozzle mounting is shown incorporated in a container structure including a body 5 having a top or breast 6 secured thereon by a conventional double seam 7.

The nozzle to be mounted preferably is molded from a deformable, resilient plastic, such as polyethylene, to include a tubular body 8 externally threaded at 9 and having an outwardly projecting abutment and protecting flange 10 at its lower end extremity, a preformed annular groove 11 spaced above said flange and an inwardly and upwardly tapered portion 12.

The container breast 6 is equipped with an upstanding neck 13 having a juncture with the breast through a smooth curve 14 and being equipped at its upper extremity with an inwardly turned edge 15 defining a nozzle receiving opening 16.

In the formation of the mounting neck the nozzle 8 is forced upwardly through the neck to cause the flange 10 to firmly abut and cover the neck and breast juncture 14 as at 17, and the neck edge 15 to become embedded and given a protective covering in the nozzle body wall as at 18. With the nozzle held in this position, a beading tool 19, shown in Figure 4 as constituting a roll but which may take the form of beading jaws or other tool forms, is applied to press an annular bead 20 into the preformed neck groove 11. It is preferred that the neck beading action be accompanied simultaneously by a formation of circumferentially spaced indents 21 in the thus formed bead and engaging in the bottom of the groove 11 in the nozzle body 8 in a manner for securing the nozzle against rotational movement relative to the breast neck 13 in which it is mounted. It will be apparent that by reason of the embedding of the neck edge extremity 15 as at 18 in the nozzle body, and the firm holding of the nozzle flange over the neck and breast juncture 14, as at 17, presentation of raw metal body or edge portions is prevented either externally or internally of the mounting.

As an alternative to the provision of the indents 21 in the nozzle securing head 20, the upper edge extremity of the neck may be serrated at 22 as shown in Figures 6 and 7, the nozzle securing bead 23 in this instance being devoid of the inward projections or indentations 21 shown in the form of the invention illustrated in Figures 1 through 5.

In the nozzle structures described hereinabove and formed in the manner described, provision is made for elliciently sealing the union between the nozzle and its metal support, without danger of the nozzle turning in its mounting When screw cap closures are applied thereon,

and provision also is made for preventing presentation of raw metal edges or portions either internally or externally of the nozzle mounting.

While specific examples of structures and method steps employed in the formation thereof are disclosed herein, it is to be understood that these structures and method steps may be varied without departing from the spirit and scope of the invention as defined in the appended claims.

I claim:
