This invention relates to container construction, and particularly a pouring spout structure therefor.

Up to the present time many proposals concerning pouring spout structure for containers have been proposed. These have taken various different forms. In all known instances the prior proposals have embodied structures which general'y project well above the top of the container and either are permanently secured thereto or are designed to be separately fastened on the container and removable therefrom. Spout structures of this kind are disadvantageous for the reason that they prevent stacking of the containers, due to the projection of the spout they interfere with labelling operation, and apart from this in many cases rather complicated structures are involved.

Moreover, in most cases, while a stopper is provided for the spout, the spout itself is not protected so that in the case of containers filled with syrup, oil or like viscous materials, the spout remains relatively sticky following a pouring operation, and thus is subject to the accumulation of dust ancl'foreign particles, as well as attracting insects.

It is an object of the present invention to avoid the disadvantages of the prior art by providing container construction provided with a pouring spout structure which is simple in character and which is so constructed that its upper extremities will neither project to any decided degree above the upper extremity of the container nor project beyond its side walls, thus permitting stacking or labelling or handling with the same amount of convenience as ordinary container structure.

A further object of the invention is to provide pouring spout structure in which the stopper for the spout opening forms at the same time a complete and effective covering for the spout structure.

A still further object of the invention is to provide a structure of this character which is simpe to manufacture and may be manufactured a a relatively low cost.

With these and other objects in view the invention consists essentially in a container formed with pouring spout structure on its upper end, whether or not the upper end takes the form of a removable cover or is merely an integral part of the container body. The pouring spout is rigidly carried by the top of the container and includes a defining wall surrounding a portion of the top provided with an outlet opening 1939, Serial No.

from the container, a portion of the wall forming aspout and sloping upwardly from the top of the container to a point substantially flush with the upper edge of the peripheral flange disposed around the top of the container, a portion of the spout structure 0 verlying the said peripheral flange and projecting thereabove only to the extent of the thicknes ployed, the wall throughout of thin material embeing at the most no higher than the said peripheral flange. The

opening from the spout is closed by container surrounded by the a stopper having formed integral therewith a cover for the pouring spout structure, whereby to enclose it completely when the stopper is in place.

In the form of container employing a general cover on the top a pouring spout structure is formed in the cover and a portion of the peripheral flange of the cover projects laterally so as to overlie the upper peripheral flange of the container and thus bridge the annular opening between the flange of the cover and the flange of the container, providing a continuous pouring spout construction which will not permit the material to drop into this space.

The invention will be erence to the following panying drawing.

Figure 10 is a top plan view of a modified form of pouring spout construction, and v Figure 11 is a transverse section taken on the line II-II of Fig. 10.

Referring to the drawing, A indicates a container which is designed to be provided with a pouring spout construction B. The pouring spout structure is designed to be provided on the upper end of the container, whether this is an integral part of the container or generally takes the form of I a removable cover. In the drawing a container with a removable cover is shown in Figures 1 to 8 and the invention will generally be described with reference to this type of structure.

Referring to Figures 1 to 8, the cover III of the container is provided with an outlet opening 'II through which the contents of the container may be discharged if desired. Surrounding the outlet opening is the pouring spout structure B which generally takes the form of a wall I2 suitably secured to the cover and pressed to form a sloped portion I3 which extends upwardly from the top of the cover to a point flush with and abutting the upper edge of the peripheral flange I4 of the cover. As shown particularly in Figure 5, the sloped portion I3 is also suitably curved as at I5 to form a gradually narrowing spout. The cover II) is. constructed so as to cooperate with and complete the spout portion I3. In this instance the cover blank as shown in Figure 9 is formed with a projecting lip I6 which may readily be cut from the waste portion of the metal H from which the blank is cut.

The lip portion I6 when the cover is pressed into its final form lies substantially in the plane of the peripheral bead I8 of the cover and projects therefrom to a desired degree. so that when the cover is pressed into the top of the container the lip I6 will bridge the intervening annular space I9 between the upper edge of the container and the bead I8 of the cover, the lip being of such a length as to terminate flush with the outer upper edge of the container. Thus, in a simple manner there is provided a pouring spout structure sloping upwardly from the top of the cover and continuing completely to the outer upper edge of the container whereby material in the container may be poured from the outlet opening II over the edge of the container without lodging in any other part of the upper surface of the container.

The wall I2 and general spout structure apart from the lip I6 is blanked from metal corresponding to that used for the container and then applied to the cover to form a rigid unit thereon. In this instance the opening II in the cover is formed with a downwardly extending peripheral flange 20, while the wall structure I2 is formed with an opening substantially corresponding to the opening I I in the cover and by means of a projecting flange which is pressed as at 2I around the flange 20 of the cover opening the wall structure I2 is secured to the cover. This provides for a structure which is rigid with the cover and also provides a solid flange depending from the cover opening of a character firmly to receive and hold a stopper which may be projected into the discharge opening II for sealing purposes, as will hereinafter be referred to.

The wall I 2 has a portion bent over at its upper edge as at 22 to form a reinforcing peripheral bead up to a point adjacent to the sloped portion I3 which forms a portion of the spout. At this point the wall structure is blanked with projecting aprons 23 which are bent down so as to flank the sloped portion I3 and in effect form a continuous side wall between the peripheral flange I4 of the cover for the container and the wall I2 of the spout construction. In blanking the aprons 23 they are blanked to shape so that they fit snugly against the peripheral wall I4 of the cover and the wall I2 of the spout construction so that in case any of the contents of the can should happen to drip over the wall I2 or the edges of the spout portion it cannot get under the sloped portion I3 into the space 24 (see Figures 2 and 8). Thusthe spout structure provides a continuous vertical wall up to the peripheral flange I4 of the cover. This is illustrated particularly in Figure 4.

The pouring spout structure according to the present invention is provided with a cover indicated generally by the letter C. This takes the form of a piece of metal which is blanked and pressed so as to provide a stopper 25 which is formed by inwardly depressing the metal, the die being of a contour to correspond with the opening II formed in the container cover. The cover for the spout structure is also provided with a projecting member 26 designed to cover the outer spout portion of the structure and a downwardly projecting peripheral flange 21 is also provided so'as to overlap the wall I2 of the spout structure. This flange 21 is carried right through so that it abuts the peripheral flange I4 of the cover for the container and thus it extends part way along the projecting portion 26 of the spout cover. The remaining portion of the projection 26 overlies the peripheral head of the cover for the container and the upper edge of the container itself so that in this area it is just the thickness of the metal itself.

The lip I6 of the spout portion which is formed from the flange of the cover for the container is concaved slightly during the pressing operation, as indicated at 28 (see Figure 6) and the outer end of the projection 26 of the cover for the spout may be downwardly turned and rounded as at 29 to firmly engage the lip I6 and to follow its contour. The side edges of the lip I6 are preferably bent downwardly as at 30 (see Figure 6) so as to rest upon the upper edge of the container and provide a reinforcement for this lip which will not tend to bend or distort when anything is placed on top of it. The projection flange depending from the opening. II in the container cover. To this end the lower portion of the stopper may be slightly bulged outwardly as at 32 so that it will more or less snap into place. Moreover, the defining walls of the stopper portion are slightly outwardly curved and this tends to exert a firm pressing engagement. The dependin: flange around the opening H prov des a sufficient area for engagement to allow for a very substantial and tight fit. It has been found that this construction will at least withstand 40 pound pressure.

To remove the cover C for the spout structure I provide a downwardly projecting skirt 33 on a rearward portion of this member which constitutes a continuation of the flange 21. This skirt 33 prejects downwardly to such an extent that it is spaced but slightly from the top surface of the cover III for the container so that by insert'ng a knife or screw driver between the top of the cover andthe skirt 33 the cover structure C for the spout may be readily pried off.

In order to provide a firm base for the prying instrument and also to avoid any possible damage .or d sfigurement of the top of the cover a special prying base may be provided by continuing the bead 22 of the wall I2 in the area corresponding to the skirt 33 of the cover structure C so as to provide an apron 34 (see Figure 2) bent to lie on top of the surface of the cover III. This may be easily formed in blanking out the wall structure l2.

As will be noted particularly from a considerat on of Figures 1 and 8. the pouring spout structure is such that the wall I2 is at the most no higher and preferably slightly lower than the peripheral flange M of the cover for the container while the l p IE projecting over the upner edge of the container is but little higher than the thickness of the metal itself. Thus. when the cover portion C for the spout structure is appled. the projecting portion 26 lying on top of the lip 16 leaves but two thin plies of metal over and above the upper edge of the container and as the cover usually projects slightly above the upper edge of the container the result is that there is but one thickness of metal projecting above the uppermost limit of the container when covered. In view of this the spout structure will not interfere with normal stacking operations as one container can be placed on top of another just as firmly as when the containers are not specially constructed with a pouring spout Moreover. it will be noted that the lip Hi projects laterally from the cover to such an extent that it lies flush with the outer wall of the container. Thus there are no projecting parts that tend in any way to hinder "the stacking of the containers or labelling since the containers can be placed in a labelling machine without the possibility of projecting parts interfering with the labelling operation.

The orifice or opening I l in the top of the container is preferably formed oval shaped. as shown in Figure 5, as this lends readily to a satisfactory pouring operation permitting air to enter the container to cause the contents to pour out smoothly.

However, any other suitably shaped opening might tion is prov ded directly in line with the corner "of the container, as clearly indicated at 35. whereas the general defining wall of the spout structure is formed by pressing the metal of the top of the In this case the sloped spout por-' container downwardly in an area surrounding the orifice 3B, producing a wall 31 which is par' tially below and partially above the level of the top of the container. This provides a construction wherein the top of the wall is in the form of a bead 38 that merges with the upper peripheral edge 39 of the container and the wall construction is such, as clearly illustrated in Figure 11, that it is lower than the upper peripheral edge of the container. This modified construction is of a. similar nature to that described and will not interfere with the stacking or labelling since there are no parts projecting above the outer defining edges of the container.

The structure illustrated in Figures 10 and 11 may also be provided with a cover of metal previously described and it will be realized that the projecting portion 26 of the cover for the spout structure will not project above the upper peripheral edge of the container to an extent more than the thickness of the metal. Thus, as the metal is very thin, of the order of 1/1000 of an inch and proportionately very much thinner than the illustrations in the drawing, the cover cannot interfere with normal stacking or labelling operations.

Preferably the wall of the spout structure is formed so that it slopes downwardly to a slight extent toward the center of the container and thus is lower at its inner endthan at the outer. This serves to avoid any possibility of catching one can on the spout structure of-another in stacking operations.

It will be realized from the foregoing that I have provided a simple, durable and serviceable spout structure for containers which will not interfere with normal handling of the container and which not only provides a handy construction for discharging the contents of the container at once or over a period of time, but in the latter case provides for a complete enclosure of the pouring spout structure so that it is sanitary, and will not permit the collection of dust on the spout structure nor tend to attract insects. At the same time the construction is such that it will permit of a tight closure at all times and also permit easy removal of the spout cover as well as permitting its easy return to normal position.

In the case where an oval opening is provided in the container top or cover the spout cover automatically seats itself in correct position and thus it is not necessary, as in the case of a round opening, to rotate the spout cover to a position where all parts fit correctly.

Various modifications may be made in this invention without departing from the spirit thereof orithe scope of the claims, and therefore the exact forms shown are to be taken as illustrative only and not in a limiting sense, and it is desired that only such limitations shall be placed thereon as are disclosed in the prior art or are set forth in the accompanying claims.
