CLOSURE WITH POUR SPOUT
A closure having a spout, and a container using such a closure are disclosed. The closure is formed of a paperboard panel surrounded by a plastic resin skirt formed around the panel in a mold. The spout is integrally molded with the skirt and is attached to an interior surface of the panel by a hinge. The spout has a floor and sides connected to the floor by hinges. The floor is positioned adjacent to a separable portion of the panel defined by perforations. Separation of the separable portion from the panel creates an opening. The floor of the spout is pivoted through the opening. The panel edges defining the opening contact the sides and force them to pivot toward the floor and form the spout. The container may be closed by pivoting the floor back toward the opening, the sides entering the interior of the container beneath the panel.

FIELD OF THE INVENTIONThis invention relates to closures which incorporate a pour spout and to containers having such closures.
BACKGROUND OF THE INVENTIONContainers holding dry granular matter such as table salt and detergent are often equipped with closures having a retractable pour spout to permit the container to be opened and the contents to be dispensed in a controlled manner. Such containers according to the prior art may comprise, for example, a three-sided metal chute that is pivotally mounted in a sidewall or a container closure. The chute is hingedly mounted to the container in an opening, and when it is desired to open the container and dispense some of its contents, the chute is pivoted about the hinge and swings out from the container. The three sides forming the chute direct the flow of the granular matter. Upon completion, the chute is pivoted so that two of the sides retract into the container and the third side, positioned between the two sides, lies flat with the surface of the sidewall or closure substantially in the same plane as the surface.
While such spouts are useful, they add expense and complications to the manufacture of the container or the closure, as the spout must be formed and then integrated into the component as a moving part. It would be advantageous to have a pour spout wherein the integration of the spout into a container closure is simplified to provide a more economical design.
SUMMARY OF THE INVENTIONThe invention concerns a closure for a container. The closure comprises a panel having a perimeter. The panel has a first surface and a second surface oppositely disposed. A skirt surrounds the panel and is attached thereto at the perimeter. The skirt extends in a direction substantially perpendicular to the panel and defines a well with the first surface. The closure also includes a spout comprising a floor portion and first and second side portions positioned on opposite sides of the floor portion. A first hinge attaches the first side portion to the floor portion, and a second hinge attaches the second side portion to the floor portion. A third hinge attaches the floor portion to the first surface of the panel. The first and second hinges are oriented substantially perpendicular to the third hinge. The spout is positioned adjacent to the first surface of the panel. A portion of the panel adjacent to the floor portion is separable from the panel to form an opening therein. The floor portion is pivotable about the third hinge through the opening. The first and second side portions are pivotable respectively about the first and second hinges to pass through the opening and form the spout with the floor portion.
In one embodiment, the skirt and the spout are formed of plastic resin and the panel is formed of paperboard. Preferably, the hinges are living hinges.
The invention also encompasses a container. The container comprises a sidewall surrounding an interior space. A bottom is attached to the sidewall, and the closure, as described above, is attached to the sidewall opposite to the bottom.
The panel 20 is surrounded by a skirt 24. Skirt 24 is preferably formed of a plastic resin and provides the structure for attachment of the closure to the sidewall 12 of the container 10. Skirt 24 extends substantially perpendicularly to the plane of panel 20 and defines a well 25 in conjunction with a surface 27 of the panel 20. Surface 27 faces the interior space 14 of the container 10. Skirt 24 has a rim 26 which allows for attachment of the skirt to the perimeter 22 of panel 20. The rim also provides stiffness to the closure and the container. A spout 28 is attached to the surface 27 of the panel 20 by a hinge 30, as best shown in
To allow the spout to form during use only the hinge 30, or both the hinge 30 and the floor portion 32, are attached to the surface 27 of panel 20. Whether floor portion 32 is attached to surface 27 or not, during molding of the skirt and spout, the floor portion 32 is positioned so as to be adjacent to a separable portion 31 of the panel 20 as shown in
Manufacture of the closure is advantageously accomplished using a cavity and core mold having a mold space that defines the skirt 24, rim 26 and spout 28 and receives the plastic resin. During manufacture, the mold is opened and a paperboard panel 20 is placed in the mold. Orientation tabs 35 (best shown in
To effect opening of the closure 18, as shown in
Closures according to the invention provide a spout for convenient opening, pouring and reclosing of the container. By integrally molding the spout with the skirt and rim efficiency of production is achieved, as fewer steps are necessary to produce a closure having a pour spout than if a spout were added separately after formation of the closure.
