Description

CROSS-REFERENCE TO RELATED APPLICATION
• This application claims the benefit of the filing date of U.S. Provisional Patent Application No. 60/667,261 filed Apr. 1, 2005, the disclosure of which is hereby incorporated herein by reference.
BACKGROUND OF THE INVENTION
• When packaging and displaying various products, such as candy, the object is often to provide an appealing visual display container, while also functioning as a storage or shipping container for the product. One such prior art display container being used for candy is shown inFIGS. 1-4. This display container includes atransparent container100 having an inwardly extendingcircular protrusion102 at its bottom end and acover104 having an outwardly extending correspondingcircular protrusion106 at its top end.
• The prior art containers provide a visually appealing display for candies and are also vertically stackable with each other. However, these containers do not fixedly interlock with each other when they are stacked due to the circular design of the protrusions, and therefore, they easily move and/or rotate during shipping or storage, which can result in damage to the candy inside. These known containers are generally unstable when stacked for shipment or storage. Accordingly, these containers often require that they be packaged in a sealed cardboard box for shipping in order to prevent any damage to the products disposed therein during shipping.
• Thus, there is an unsolved need in the art for display containers which overcome the problems associated with these known containers, such as those noted hereinabove that may occur during shipping and storage.
SUMMARY OF THE INVENTION
• The present invention generally relates to a display container having a cover. In accordance with one embodiment, a container includes a shell having a bottom with an inwardly extending non-circular protrusion and an open top; and a cover for the open top of the shell having an outwardly extending non-circular protrusion.
• Still more particularly, the invention relates to a container having a closed bottom section with an inwardly extending protrusion, and interconnected side walls connected to the bottom section; and a cover for the display container having a closed top section with an outwardly extending protrusion, and interconnected side walls connected to the top section. The outward protrusion located at the top of the container cover will interlock with the inward protrusion in the bottom of the adjacent container when the containers are stacked on top of each other making them substantially immovable and thus less susceptible to damage during shipping and storage.
• It is one aspect of the present invention to provide a container and cover combination comprising a container having a bottom with an inwardly extending non-circular protrusion and an open top; and a cover for said open top of said container having an outwardly extending non-circular protrusion, wherein said protrusion of said container and said protrusion of said cover are configured to interlock with each other when nested within each other to prevent rotation therebetween.
• It is yet another aspect of the present invention to provide a container and cover combination comprising a container having a bottom with an inwardly extending opening and an open top, and a cover for said open top of said container, said cover having an outwardly extending projection, said projection releasably nestable within said opening when said container is supported on said cover, said opening and said projection each having a shape which prevents rotation of said cover relative to said container when said projection is nested within said opening.
• It is also an object of the display container disclosed herein to provide a container with cover for displaying various products in an attractive and reliable manner while also discouraging the unintentional discharge of or damage to the products disposed therein during shipping and storage.
• The display container of the present invention preferably includes a transparent container with a closed bottom section with an inwardly extending non-circular protrusion; and a cover for the container having a closed top section with an outwardly extending correspondingly shaped non-circular protrusion.
• The preferred display containers of the present invention includes polygonal shaped protrusions at the top of the cover and at the bottom of the container so that they can be interlocked when the containers are stacked on top of each other.

DETAILED DESCRIPTION OF THE INVENTION
• In describing the preferred embodiments of the present invention, specific terminology will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and is understood that each specific term includes all technical equivalence which operate in a similar manner to accomplish the same purpose.
• Referring first toFIGS. 5-8, there is shown, according to one embodiment of the invention, atransparent container1 with a closedbottom section3 with an inwardly extendingnon-circular protrusion5 or opening, and interconnectedside walls10 connected to thebottom section3 forming an open top container. Thecover20 of thedisplay container1 has a closedtop section23 with an outwardly extendingnon-circular protrusion30 or projection surrounded by arecess25, and interconnectedside walls35 connected to thetop section23. Theprotrusion30 extends above thetop section23. Thetop section23 of thecover20 and thebottom section3 of thecontainer1 are essentially flat, so that they are in contact when stacked on top of each other, either during shipment or when in use as described hereinafter. Thecontainer1 andcover20 may be made of any suitable material. The preferred material is plastic and can be transparent or of any color desired. Preferably thecontainer1 is transparent to allow the product with the container to be visible to the consumer. Thecover20 may also be of any color or transparent.
• It is to be understood that although thecontainer1 has been shown as havingsidewalls10, the container may be of any shape such as round, oval, polygonal, square, or the like. Thecover20 may also be of other shapes, preferably being the same shape as thecontainer1.
• The shape of the outwardly extendingprotrusion30 of thecover20 and the inwardly extendingprotrusion5 of thedisplay container1 can be of any angular or non-circular shape that would prevent the containers from rotating when stacked on top of each other. For example, the shape of the protrusions may be octagonal, triangular, rectangular, trapezoidal, polygonal, +sign, − sign or any other such shape. As shown inFIGS. 8-9, the preferred shape of the outwardly extendingprotrusion30 of thecover20 and the inwardly extendingprotrusion5 of thedisplay container1 is polygonal. In this regard, theprotrusions5 and30 will nest inside one another to prevent the stackedcontainers1 from rotating relative to one another.
• In addition, the shape of the outwardly extendingprotrusion30 of thecover20 and the inwardly extendingprotrusion5 of thedisplay container1 may be of different shapes and sizes with respect to each other as long as they are configured to interlock with each other when nested within each other to prevent rotation. For example, the shape of the outwardly extendingprotrusion30 of thecover20 may be a + sign, and the shape of the inwardly extendingprotrusion5 of thedisplay container1 may be a − sign.
• Moreover, the outwardly extendingprotrusion30 of thecover20 and the inwardly extendingprotrusion5 of thedisplay container1 are sized so that when they are nested in each other, they do not become stuck in each other.
• As shown inFIGS. 9-10, thecover20 can be removably fixed on the top of thecontainer1. In order to obtain a good seal, thecover20 has at least one outwardperipheral edge51 as shown inFIG. 9, which can grip over at least one outwardperipheral edge56 of thecontainer1 as shown inFIG. 10.
• As shown inFIGS. 11 and 12, thecover20 may includelabels61 attached to theside walls35 of thecover20. Thelabels61 may contain any texts or graphics that a user would like to incorporate in order to make the display container more attractive and appealing, including product identification and advertising labels.
• In the embodiment illustrated inFIG. 12, MilkyWay®candy bars60 are housed in thedisplay container1. However, the present invention is not limited to storing only candy products, but any other products desired, such as hard candy, pencils, key chains, novelty items, etc. Because the display containers of the present invention interlock and do not rotate when stacked on top of each other, the display containers can be used as reliable storage and shipping containers. A plurality ofstacked containers1 are shown inFIG. 13. Because the display containers also provide reliable shipping containers, the display containers filled with fragile products do not need to be packaged in a sealed cardboard box. Instead, a large volume of display containers of the present invention filled with fragile products can be shipped to a destination on a pellet with shrink-wrap around them.
• In use of thecontainer1 as shown inFIG. 14, thecover20 may be removed and used as a supporting base for the shell12. In this regard, thetop section23 of thecover20 will support thebottom section3 of the container, with theprotrusions5 and30 nested within one another thereby preventing rotation of the container when in display mode for sell the contained product to the consumer.
• As these and other variations and combinations of the features discussed above can be utilized without departing from the present invention as defined by the claims, the foregoing description of the preferred embodiments should be taken by way of illustration rather than by way of limitation of the invention as defined by the claims.
