PLASTIC CONTAINER SPOUT SUMMARY OF THE INVENTION This invention relates to container pouring spouts for easy application and cooperation with the outer surface of a container such as a can, and is particularly efficient when used with cans having a beaded chime. The spout is preferably formed from an unsupported sheet of resilient, elastic plastic material such as high density polyethylene. The spout is provided with an integral band which is slipped about the can. In the retracted position, the spout is in a snug can encircling arrangement providing substantially no interference to the packaging of a plurality of cans carrying the spouts in standard can cartons. Once the can is opened for use of the contents, the spout is easily slid to the pouring position.

It is the principal object of the present invention to provide a simple container spout for the outer surface of a container which is easily applied, compactly car- Other objects and features of the invention will be apparent upon a perusal of the following specification and drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a plan view of one embodiment of the invention as it is formed from a sheet of plastic material;

FIG. 2 is ,aside elevational view of a container with the spout of FIG. 1 applied thereto and in the retracted position;

FIG. 3 is a perspective view of the arrangement of FIG. 2 with the spout and canin pouring position; I

- FIG 4 is a plan view of another embodiment of the.

FIG. 5 is a perspective view of a container with the DESCRIPTION OF THE PREFERRED EMBODIMENTS Each of the embodiments 10, ll, 12 and 13 of the spout of the present invention is formed from a flat spout of FIG. 4 applied thereto and theretracted position; and

sheetof material, preferably an unsupported sheet of a resilient, elastic, plastic material such as high density polyethylene.

Each of the spouts'l0, ll, 12 and 13 has a base portion and side edges converging to a tip portion. With such a shape, it is contemplated that the spouts can be formed from a continuous strip or web of material by a base-to-tip alignment of side-by-side spouts.

In the embodiment of FIGS. 1-3, it may be seen that the side edges of the base portion are formed with rounded corners. The base portion includes anintegral band 14 which is formed by slitting or-otherwise cutting.

the sheet material along a line spaced from the marginal edge thereof and following the rounded corners substantially to a point where the rounded corners terminate at the straight side edges of the spout 10. The width of the base portion is correlated to the circumference of the container 15 to which the spout 10 is to be applied so that when the band 14 is drawn away from the remainder of the spout 10, a container encircling hole is defined which permits the spout 10 to be snugly applied circumferentially of the container 15 as may be seen in FIG. 2. The resiliency of the material insures a snug association of the spout 10 with outer surface of the container 15.

In each of the

spouts

10, 11, 12 and 13, the converging angle of the side marginal edges and the length are correlated to the height and circumference of the container to which the spout is to be applied so that the spout when applied to the container is no longer than the container, and when projected axially of the container to pouring position, as in FIG. 3, the spout is curved in the shape of a trough with side walls decreasing ti the tip portion. In the embodiments of the inven:

tion shown in FIGS. 1-3 and 7 the side walls of the spout will extend circumferentially further about the container than will the side walls of the embodiments of FIGS. 4-6.

Scored or weakening lines 16 may be provided on the spout 10 to produce a configuration at the tip portion which is more V-shaped than semi-circular. The lines 16 are preferably positioned parallel to the side edges of the spout 10.

The spouts 10, ll, 12 and 13 are particularly efficient when used with containers or cans having a beaded chime because with such containers the spouts are inherently locked on the containers against accidental endwise removal. This feature is emphasized when in'the formation of the spouts, the edges of the container encircling band and the edge of the base are sharply defined. In any normal movement of the spout to either the retracted'or pouring positions, the spot will engage the chime and be positively retained on .the container;

V In the embodiment of the invention shown in FIGS. 4" and 5, the container encircling band 17 in a-flat condi-- tipack by securing the handles 18 of a number of spouts together.

In the embodiment of the invention shown in FIG. 6

the band 21 is curvilinear and thereby provides a' greater ratio of band length to base width than in the embodiment of FIGS. 1-3. The spout 12 is further provided with a lip portion 22 which will extend substantially axially from the rim of the container toward the bottom end when the spout 12 is in pouring position of a container. The score lines on spout 12 are shown at the band defined by

slits

24 and 25 is drawn outwardly 1 of the remainder of the spout to define a containerencircling shape. As with spout 12, the portion 26 will extend axially along the containerwhen spout 13 is positioned in pouring position on a container. The score lines on spout 13 are shown at 27.

I claim:

1. A spout for embracingly encircling a complementary container, said spout formed from a sheet of flexible material and comprising a body portion in the general shape of a trapezoid and an integral band lying in a common substantially flat plane, the ends of said band being integrally connected to the opposite ends of one end of the generally parallel ends of said body portion, the non-parallel sides of said body portion converging from said one end toward the other end thereof, said band and said one end having a combined length permitting said band and said one end to be placed in container encircling relationship on a complementary container.

2. In a spout as defined in claim 1, and score lines formed in said body section and extending longitudinally thereof between said one end and said other end.
