VIA Il fili/Iliff!!! NOZZLE CGNTAlNElR WITH FLEXIBLE TELESCOPING POURING SPOUT Walter Il. Dobbins III, Little Falls, N. J., assignor to` American Can Company, New York, N.v Y., a corporation of New Jersey The present invention relates to containers having nozzles embodying retractable, telescoping or extensible pouring spouts for dispensing the contents of the containers and has particular reference to a exible or resilient tubular pouring spout. This is an improvement over the pouring spout disclosed in United States Patent 1,773,846 issuedAugust 26, 1930, to Henry M. Nicholls.

ln the manufacture of containers having telescoping or extensible pouring spouts, the spouts are usually made of sheet metal and slidably embodied in a nozzle which is secured to the container and which is closed and sealed with a screw cap. ln spouts of this character it is difficult to provide for a leakproof tit around the mouth of the nozzle while simultaneously providing for easy sliding of the spout in the nozzle. Another diticulty is in providing means for retaining the spout in the nozzle and for easy` assembling of the spout with the nozzle.

An object of the instant invention is the provision of a telescoping pouring spout which overcomes these diiculties wherein the pouring spout is madey of a tlexible or compressible material and is so proportioned that it may be readily pressed into place within the mouth of a nozzle after the nozzle is secured to the container.

Another object is the provision of such a pouring spout for a nozzle container wherein the spout is loosely supported in the nozzle for easy sliding movement therein but upon withdrawal into extended dispensing position, lits tightly in the nozzle mouth in leakproof frictional engagement with the nozzle, without requiring a separate gasket, to hold the spout in extended position and to facilitate dispensing of liquid products without leakage around the spout. *f

Another object is the provision of such a pouring spout for a nozzle container wherein a flange portion on the nozzle serves a dual purpose of retaining the spout in retracted or non-pouring position andmore importantly providing a gasket for the cap which closes the nozzle, so that the usual separate expensive gasket in the cap may be eliminated.

Numerous other objects and advantages of the inven* tion will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Figure 'l is a perspective view of a nozzle container sealed with a screw cap and tted with a telescoping pouring spout embodying the instant invention;

Fig. 2 is a perspective view of the pouring spout used in the container shown in Fig. l;

Fig. 3 is a sectional view taken along a vertical plane indicated by the lines 3--3 in Fig. 1 with parts broken away; and

Fig. 4 is a view similar to Fig. 3 having the cap removed from the nozzle and showing the pouring spout extended outwardly in dispensing position.

As a preferred or exemplary embodiment of the in vention the drawings illustrate a container A (Fig. l)

nited States Patenti() ice Patented Dec. 1.1, 195s having an extensiblepouring spout B (Fig. 2) for holding and dispensing liquid contents although the invention is equally well adapted to dry and granular products and other substances. The container preferably comprises a cylindrical sheet metal body 11 having top'and bottom end members 12, 13 respectively secured thereto in suitable end seams14.

The top end member 12 preferably is provided with a dispensing opening 16 (Figs. 3 and 4) having secured therein in any suitable manner, a sheet metal nozzle 17 which projects upwardly above the top of the container. At its lower end the nozzle 17 preferably is attached to the top end member 12 by an interfolding of a flange 18 of the nozzle aroundthe edgeof the top end member defining the opening 16. At its upper end` the nozzle 17 is formed withy an inwardly and slightly upwardly inclined at flange, rim or seat 19 which merges into a short depending skirt 21 defining a mouth 22 for the nozzle.

The nozzle 17 is providedfwith a gasketless screw cap 24 having a llat imperforate top 25 and a depending skirt 26 which extends down around the nozzle 17. The skirt 26 is formed with screw threads 27 for cooperative action with similar screw threads 28 in the nozzle 17 for securing they cap to thel nozzle tol close the container.

Theextensible spout B when assembled with the container is located in the mouth 22 of the nozzle 17, and is-preferably made of a resilient compressible or flexible plastic material commercially known as polyethylene or other suitable substance. The spout B preferably is made in one-piece and comprises a cylindrical tubular seamless body 31 of a-uniform diameter slightly smaller than the inside diameter of the nozzle skirt 2-1, for a loose tit in the nozzle mouth 22.

Adjacent its lower end the spout body 31l is formed with a thickened friction portion or collar 32 of a diam eter substantially equal to or slightly larger than the inside diameter of the nozzle skirt 21 to produce a tight friction lit against the nozzle skirt. The lower end of this friction collar 32 merges into an annular stop shoulder 33 having an external diameter substantially greater than the diameterfof the mouth 22 of the nozzle 17 and constitutes a portionof an inserting head 34 formed on the inner terminal end of the spout. The head 34 is provided with a downwardly and inwardly tapered outer face 35 to facilitate insertion of the spout within the nozzle mouth 22. At its upper end, the spout body 31 is formed with an annular flange 37 of an external diameter slightly less than the outside diameter of the nozzle 17 for overlapping engagement with the seat 19 of the nozzle.

The extensible spout B is adapted to be-inserted into the nozzle mouth 22 after the nozzle 17 is assembled with the container 11'. This is one of the reasons ythe spout is made of'a resilient or compressible material. By positioning the tapered head 34 in the nozzle mouth 22 with its tapered face 35 against the edge of the nozzle skirt 21 surrounding the mouth and applying a slight pressure on the spout in the direction of the nozzle, the tapered head 34 of the spout may be readily pressed into and through the nozzle mouth 22 thereby assembling the spout with the container as shown in Fig. 3. When the spout is in fully assembled relation with the nozzle as shown in Fig. 3, its top tiange 37 rests on top of the seat 19 of the nozzle and thus prevents the spout from falling all the way into the container. In this position the spout flange 37, being also of a resilient nature, serves as a gasket for the cap 24. The tlange 37 thereby eliminates the extra need and cost of a separate gasket in the cap as is usually provided. A similar separate gasket is also eliminated at the bottom end of the spout B, the thickened compressible collar 32 taking the place of such a gasket when the spout is in extended position (Fig. 4).

When it is desired to dispense the contents of the container A, it is merely necessary to remove the cap 24, and

lift the spout B, by its flange 37, into the dispensing position shown in Fig. 4. In this position, the stop shoulder 33 of the spout head 34 is in tight engagement with the lower terminal edge of the nozzle skirt 21 and the integral friction collar 32 of the spout is wedged tightly against the inner face of the nozzle skirt 21 thereby providing a liquid tight fit of the spout within the nozzle mouth 22 which retains the spout in its extended dispensing position and simultaneously prevents leakage of the container contents around the spout in the mouth of the nozzle.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
