Box with widest possible pouring spout

Abstract

The present invention is directed to a box with the widest possible pouring spout. The spout is an integrated portion of the box with no additional or external portions required for manufacture. The spout has a means by which a person using the spout may conveniently open the spout, a means by which the spout will be secured from opening beyond the position required for maintaining the spout pouring area and a means by which the spout will be secured in a closed position when not in use. Because the spout is an integrated portion of the box, the box with widest possible pouring spout will be efficient and economical to produce and will provide the largest possible pouring area for large, bulky or cumbersome products.

Description

FIELD OF THE INVENTION

The present invention relates generally to fibrous structures, and more particularly to a box-like container which has the widest possible integrated pouring spout, thereby providing a larger opening for more efficient pouring of coarse or larger materials.

BACKGROUND OF THE INVENTION

Although many pouring spout arrangements have been devised in the past, very few have gained commercial acceptance. One of these is a metal spout attached to the end panel of a cardboard box and covered with paper for sealing prior to the opening of the spout. This type of spout is not only expensive to produce, but is limited in size and thus has insufficient pouring areas useful for pouring course or large products such as course or bulky products.

Plastic spouts in the top of a box have also been designed, however, again the design requires the attachment of a separate element and is also relatively small in size, again prohibiting the dispensing of coarse or large products and are relatively expensive to produce.

As a consequence, there has been a need for an improved pouring spout with the largest possible opening for use in dispensing products which are larger, course or bulky in nature which is also efficient and economical to manufacture.

In this respect, before explaining at least one embodiment of the invention in detail it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

SUMMARY OF THE INVENTION

The present invention provides an improved pouring spout arrangement which requires virtually no added expense in producing a cardboard box. The spout will provide for the easy pouring of the material from the box and can be closed once the material has been dispensed. This spout arrangement provides for the largest possible spout opening which is important for materials that are large or bulky or which tend to form lumps.

The spout arrangement provides a cardboard box made from a single sheet of material defining two opposite end panels, one of which has two layers, positioned one on top of the other. The outer layer includes a cutout for a portion of the closure flap, pivotal about its lower edge with an opening above it. Additionally, the outer layer has a reinforcing flap which will adhere to the side wall frontal or rear portion of the box as a stabilizing feature of the structure.

The inner layer has a remainder of the closure flap which is pivotal about its lower edge and bendable transversely at its intermediate portion. Above the bendable portion the inner layer is attached to the outer portion of the stationary side of the cardboard box and will act to secure the pouring spout in a closed position when not in use. Above the bendable portion it is attached to the outer portion of the stationary side wall.

The box is opened by pulling outwardly on the closure flaps to pivot them about the lower edges. This removes the bottom closure flap from inside of the opening and causes it to bend transversely, uncovering the openings through the end panel of the box. The closure flaps may be retained in the opened position by locating the top edge of the closure flap adjacent the pivot point of the closure flap bearing, against the wall of the outer panel on either side of the opening. Therefore, it is unnecessary to hold the pouring spout open manually as the contents of the box are being dispensed.

The spout is closed by reversing the operation and inserting the bottom edge of the closure flap inside the lower edge of the stationary cutout in the inner panel.

The principle object of this invention is to provide for the largest possible opening for a pouring spout arrangement on a cardboard box.

Another object of this invention is to create a pouring spout arrangement that is an integral portion of the cardboard blank from which such a box is constructed with no need for additional element.

It must be clearly understood at this time although the preferred embodiment of the invention consists of the pouring spout which is an integral portion of the cardboard blank from which a cardboard box is manufactured, that many conventional pouring spouts exist that will achieve the a similar operation and they will also be fully covered within the scope of this patent.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
