ATTORNEYS Patented Mar. 21, 1944 CONTAINER George E. Eckman, New Milford, N. J., assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application May 31, 1941, Serial No. 396,231

4 Claims.

This invention relates to a pouring spout liquid can or container and has particular reference to a nozzle type can having a detachable and reversible pouring spout for dispensing liquid contents from the can when in an extended position, the spout having a splash guard at its upper end when it is in non-pouring position within the nozzle so as to relieve air pressures from within a sealed container when first it is opened thus preventing splashing out of the liquid contents preparatory to arranging the spout for dispensing.

In certain respects the present invention constitutes an improvement upon the dispensing container illustrated and described in the John M. Young United States Patent 2,010,048, issued August 6, 1935, and is especially directed to a non-splashing pouring spout.

An object of the invention is the provision of a can or container having a discharge nozzle or outlet in which a pouring spout is adapted to be inserted, the nozzle being sealed by a spring finger type of closure, the spout being formed with a splash guard at one end, a depending wall of which is undulated so that air or gas pressures in the contents of the can may be vented when the can first is opened, thus preventing splashing or upward surging of its contents prior to or while the spout is being withdrawn as when preparing it for a dispensing operation.

Another object of the invention is the provision of such a can for holding liquids wherein the splash guard is formed to frictionally engage inside the nozzle to hold the spout in a pouring position, the spout initially being carried in a non-pouring position inside the can and being supported within the nozzle, such a spout being removable and reversible to place it in pouring position.

A further object of the invention is the provision of a reversible spout of the character described having a vent opening in its head and having a semi-circular removable area which, after the container is opened, may be cut along a curved boundary line and the cut out metal may be hinged or bent along a straight uncut side to produce a semi-circular pouring opening in the spout as an incident to adapting the spout for dispensing of the can contents.

The invention also contemplates a can construction which includes a nozzle and an insertable tubular pouring spout, one end of which is provided with an outlined area adapted to be pressed inwardly to produce a pouring opening in the spout. This end of the spout also has a vented opening which is spaced opposite the pouring opening so that air can be admitted into the can-after the can contents are vented to control the discharge of liquid in a steady even flow as such contents are dispensed through the pouring opening of the spout.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the [accompanying drawing, discloses a. preferred embodiment thereof. I

Referring to the drawing:

Figure 1 of the drawing is a fragmentary perspective view of a can embodying the present invention showing the nozzle of such a can completely sealed by a supplemental spring finger type of closure;

Fig. 2 is a fragmentary enlarged vertical sectional view showing the pouring spout as it. appears initially as when carried inside thesealed can of Fig. 1;

Fig. 3 is an end view of the pouring spout before the pouring opening is formed in the end wall thereof; and

Fig. 4 is a view similar to Fig. 2 illustrating the pouring spout in reversed or pouring position and with the pouring opening formed and the spout ready for dispensing the can contents.

As a preferred embodiment of the invention, the drawing illustrates a can body II having a top end or cover l2 secured thereto in any suitable manner as by a double seam E3. The cover 12 is provided with an opening [4 (Figs. 2 and 4) which preferably is located in a sunken panel l5 adjacent an edge or the periphery of the can end.

A nozzle It is secured to the marginal edge surrounding the opening l4 in a suitable joint [8. This nozzle is formed at its upper end with an annular beaded shoulder l9, the upper edge of which is curled inwardly as at 22 to provide a smooth mouth for the nozzle. I

A protective cap 23 having slit spring fingers 24 and a domed flexible depressible center portion 25 may be used for closing the open end oi the nozzle. Such a cap carries a gasket 25 which is formed of cork or other suitable gasket material and is adapted to rest on the curled nozzle edge 22 when in closing position. The spring fingers 21 are pressed inwardly and engage under the shoulder l9 when the cap is in sealing position. The domed center 25 of the cap being flexible, holds the fingers under the shoulder when it is in the raised position shown in Fig. 2. When pushed or pressed inwardly this center springs the fingers outwardly from the shoulder l9 of the nozzle. Such a closure cap is well known in the can closure art.

A reversible and detachable pouring spout 2'! comprises a cylindrical or tubular body 28 (Figs. 2 and 3) which is cut away at its spout end as at 29. A head 32 is ecured to the opposite end of the tubular body in any suitable manner. This head has a sunken panel section 33 and an outwardly extended flange 34, which merges into a tapered outer wall 35. The inner surfaces of the flange 34 and the wall 35 constitute a splash guard area 36 for the spout.

The edge of the flange Wall 35 is ofundulating configuration, as illustrated in Figs. 2, 3 and 4 of the drawing, and such formation is ei fected by extended lugs 31. These lugs as well as the flange wall are flared. or tapered as shown in Fig. 2. The lower edge of the lugs 31, when the spout is being carried. in the nozzle and is in non-pouring position, rests. on an inserted ring 38 (Fig. 2) which is permanently held inside the nozzle.

The sunken panel 33 in the head of the spout is cut through in a semi-circular line 39- (Fig.3) which sets oft" a removable area which. occupies substantially one-halfof the end wall area. The other half of the wall is perforated in a vent opening 42. The size ofthe opening area and the size of the vent opening are such as to provide for the best dispensing action, as hereinafter explained.

In the initial carrying or non-pouring position (Fig. 2) of the spout 21', it is enclosed fully Within the can. Its tubular body 28 extends down into the liquid contents and at sucha time its head 32 is located substantially on ahorizontal plane with the. beaded shoulder IQ of the nozzle [5.

Ring 38 is formed at the top witha substantially U-shaped section 44 having an outer annular wall 45 which may fit. tightly within the nozzle wall to form a permanentjoint. An inner wall 46 of the ring is tapered downwardly and terminates in a ledge 47. In its non-pouring position (Fig. 2) the spout lugs 31 rest on the pressing down on its flexible domed center 25 so that the fingers 24 spring out of engagement from the nozzle shoulder l9} At. such a time the spaces between the lugs 31 of the ring 33 serve for venting abnormal air or gas pressures which may exist in the head space of a filled container at the time. Any tendency of. they liquid contents to surge or splash is-conflned. within the splash guard 3.6 of the. spout. With such. a construction, a balanced atmosphericpressure-is immediately set up in the can and further steps for dispensing the contents proceed.

The pouring spout. 2T. first is made ready for its withdrawal from the can. Incidental to such Withdrawal a dispensing opening is made in the sunken panel section 33. of the spout. This accomplished by bending the semi-circular removable area, which is set ofi by the curved line of cut 39, along a line of bend 48 (Fig. 3). Such an area is pushed intothe spout body, as best illustrated in Fig. 4, and this produces a pouring opening 49 in the spout.

The pouring spout may be withdrawn from the can by inserting the finger in the pouring opening. Now the spout is reversed or turned around and its head end is inserted inside of the nozzle in its pouring position as shown in Fig. 4. During such insertion, the tapered wall 35 of the spout is forced inside of the tapered friction wall 46 of the ring member 38 until the extended flange 34 of the spout is fully seated against the ledge 41 of the ring. There is considerable spring in the spout wall 35 so that the fit is close enough to maintain the spout rigid. Such a spout preferably is positioned so that a pouring, lip, designated by the numeral 52, is

toward the nearest edge of the container.

With the spout in pouring position, the can may be tilted so that the liquid contents flows out through the pouring opening 49 in the spout. The wall 33 of the sunken panel abovev the line of bend 48 blocks off the stream ofv liquid, thus preventing the contents from completely filling the spout. At the same time air passing free.- ly through the vent opening 42. andv passing through the liquid contents, replaces the displaced liquid. This gives an. even flow of. liquid and controls the discharge.

After dispensing the. desired amount of the contents, the can is righted and is prepared for reclosure. This is accomplished by merely re.- moving the spout from its frictional engagement within the inserted ring of the nozzle, reversing it and again placing it in its non-pouring position as before. The can may bereclosed by the same protective cap 23.

It is thought that the invention and many of its attendant advantages will beunderstood. from the foregoing description, and it willbe 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;
