The spout is a one piece pliable plastic member having a base with an arcuate groove with a radius of curvature larger than the radius of curvature of the container lip and a sheet chute member attached to the base. The chute member is flexed to a generally U shaped trough configuration when the base is mounted on the lip of thecontainer.
10 Claims, 5 Drawing Figures CONTAINER SPOUT BACKGROUND OF INVENTION 7 Conventional containers for materials and liquids have a generally U shaped annular sealing groove for, receiving a cover to close the container. An example of this type of container is a paint can having a sealing groove and a circular lip terminating on an annular bead surrounding the top opening of the can. In the process of mixing and pouring paint from a can it is practically impossible to prevent paint from accumulating in the sealing groove and running down the outside of the can. The top of the pail does not serve as a guide or function as a pouring spout to minimize the spilling of the paint. This problem is present in many containers that are used to store fluids and like materials.
SUMMARY OF INVENTION The invention is directed to a spout adapted to be releasably mounted on a container to serve as a pouring spout as well as a means to scrape clean or wipe the contents of the container from a tool such as a paint brush. The spout has a base means and chute means attached to the base means. The base means includes an attaching structure to releasably mount the spout on the container adjacent the opening of the container. The base has an arcuate groove for receiving the bead and lip of the container in a manner so that the con tents of the container do not spill into the sealing groove for the cover of the container and run on the outside surface of the container.
The chute means comprises a generally flat sheet like member attached to the base means. When the base means is mounted on the container, the chute means is flexed or bent into a generally U shaped or trough like extension which serves as a guide for pouring the contents from the container. The chute means has an upper edge which also functions as a scraping edge to clean and wipe off tools whereby the excess material flows back down the chute means and into the container.
The arcuate groove in the base means has a radius of curvature which .is larger than the radius of curvature than the container bead so thatwhen the spout is mounted on the container bead the chute means is flexed into a generally U shaped trough configuration. The lower portions of the opposite sides of the chute means have upwardly directed side walls to direct the contents remaining on the chute means back into the container and prevent the contents from entering into the sealing groove of the container.
IN THE DRAWINGS FIG. 1 is a perspective view of the spout of the invention mounted on the lip of a container;
FIG. 2 is an enlarged sectional view taken along the line 2--2 of FIG. 1;
FIG. 3 is a top plan view of the spout;
FIG. 4 is an enlarged sectional view taken along the line 4--4 of FIG. 3 and;
FIG. 5 is a sectional view taken along the line S-5 of FIG. 4.
Referring to the drawing as shown in FIG. 1, the spout of the invention indicated generally at mounted on a container 11, as a paint can or pail. The
container 11 is shown as a conventional gallon pail or can for storing paint, food products, oil, chemicals, granular materials and the like. The spout 10 is usable with different sized containers, as a quart can, for directing the contents of the container in a defined and controlled manner. Container 11 has an opened top or mouth 12 surrounded by an upwardly directed circular lip 13. The lip 13 terminates in a circular bead 14. Located outwardly around the lip 13 is a sealing groove 16 adapted to receive a downwardly directed annular portion of the cover (not shown) for the container.
Referring to FIGS. 3, 4 and 5, the spout 10 is a one piece, generally flat, and flexible or pliable member. Preferably, the spout 10 is a one piece molded plastic member made of flexible low cost plastic material, as a low density polyethylene and like material. The chute 10 has an arcuate base 17 and a chute member 18 joined to the convex side of the base. The base 17 has an arcuate concave shape which faces the open top or mouth 12 of the container. The bottom side of the base 17 has an arcuate groove 19 having a generally square cross section configuration. Two arcuate continuous flanges 21 and 22 are located on opposite sides of the groove 19. Arcuate flange 21 projects outwardly and downwardly from the back side of the base. The lower face 21A of the flange 21 functions as a locating means and guiding means for directing the bead 14 of the container into the groove 19. The base 17 has a generally overall triangular cross section with an arcuate top face 23 extended down to the upper surface of the chute member 18. As shown in FIG. 3, the radius of curvature of the base 17 and groove 19 is substantially larger than the radius of curvature of the bead 14 of the container when the spout 10 is detached from the container. This relationship exists when the spout 10 is in its generally flat shape. As a specific example the radius of the base 17 can be equal to the diameter ofthe bead 14.
Chute member 18 has a transverse top edge 24 and upwardly and inwardly tapering side edges 26 and 27. The bottom surface of the chute member 18 is flat and continuous with the flat bottom of the base. The opposite sides of the lower portions of the chute member 18 have upwardly directed side walls or gusset wedges 28 and 29 extended forwardly along the sides 26 and 27. These side walls 28 and 29 function as stops or dams to direct the material over the top face 23 and into the container. This prevents the material from flowing into the sealing groove 16.
In use, the spout 10 is snapped onto the head 14 of the container. The bead 14 of the container is located adjacent the mouth of groove 19 by the flange 21. The lower face 21A of the flange serves as a guide directing the bead 14 into the groove 19. The spout 10 being of flexible material follows the curve of the bead 14 which is snapped into the groove 19. The curvature of the groove 19 being larger than the curvature of the bead 14 holds the flanges 21 and 22 in close sealing engagement with opposite sides of the lip 13. The chute means 18 is flexed or bent into a generally U shaped trough configuration extending outwardly at an angle at approximately 30 with respect to the horizontal plane at the top of the container.
The spout 10 can be formed with side ears or lugs 31 and 32 used to attach the spout to a display base or card. The ears 31 and 32 are made of relatively thin plastic material so that they can be readily removed from the sides of the spout. The ears 31 and 32 are adapted to receive fasteners, as staples, to mount the spout on a display card. A number of spouts can be attached to a single display card.
A specific example of the removably mounted spout of the invention is set forth in the following detailed description. The spout can have other sizes and shapes. This spout is a one piece molded flexible plastic member having a base of arcuate configuration approximately 7 inches in circumference with a radius of 5% inches. The chute member is three sixty-fourths of an inch sheet material having a top width of 5% inches and a bottom width of 6% inches. The sides 26 and 27 are 2% inches long. The side walls 28 and 29 extend approximately 1 inch upwardly from the center of the base means 17. The groove 19 is a %-inch diamond shaped having a depth of approximately one-eighth inch.
The above description and drawings are directed to a preferred embodiment of the spout. It is intended that various omissions, substitutions, changes in size, changes in dimensions and size of the materials may be made by those skilled in the art without departing from the invention.
