DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
Referring to FIGS. 1-6, a container 10 of the present invention is depicted. The height and shape of the container may vary from that shown without departing from the scope of the invention. For example, the container 10 is shown as being generally rectangular, but it is contemplated that other shapes like a square or other polygonal shapes may be used.
The container of the present invention is typically used to hold food, but may be used in other applications such as with medical applications, cosmetics, craft supplies or other items. The food container may be used for serving, storing, preparing and/or re-heating the food such as pre-packed meals. The container of the present invention may have insulating properties to assist in maintaining the temperature of any food contained therein. One example of such a container is an alkenyl aromatic container.
Referring specifically to FIGS. 1-4, the container 10 includes a continuous body portion 12, a continuous rim 14, a first minor flap 16, a second minor flap 18, a first major flap 20 and a second major flap 22. The first minor flap 16, the second minor flap 18, the first major flap 20 and the second major flap 22 are adapted to fold together to form a closed container with a handle.
According to this embodiment, the first and second minor flaps 16, 18 are identical to each other. It is contemplated that the first and second minor flaps may be substantially identical to each other, although it is not necessary that the first and second minor flaps be either substantially identical or identical with each other.
According to this embodiment, the first and second major flaps 20, 22 are identical to each other. It is contemplated that the first and second major flaps may be substantially identical to each other, although it is not necessary that the first and second major flaps be either substantially identical or identical with each other.
The body portion 12 includes a bottom 24 and a sidewall 26 that encompasses and projects upwardly and outwardly from the bottom 24. It is contemplated that the sidewall may project only upwardly from the bottom. To provide enhanced carrying strength, the continuous body portion 12 is integrally-formed (i.e., solid) and is not formed by folding the sidewall with respect to the bottom. Thus, the continuous body portion 12 is non-foldable. The integrally-formed, non-foldable continuous body portion 12 also assists in preventing or inhibiting leakage therefrom. The bottom and/or sidewall may include ribs for additional carrying strength.
The continuous rim 14 encompasses and projects laterally outwardly from the body portion 12. The rim, however, may be discontinuous, although it is preferred to be continuous. The rim is advantageous for a number of reasons including providing supporting strength when the container is being placed in the closed position. Additionally, the process of making the container, such as by thermoforming, is made easier by using a rim. According to another embodiment, the container may be formed without a rim. In such an embodiment, the minor flaps and the major flaps are integrally connected to the sidewall along respective fold lines.
The first minor flap 16 is integrally connected to the rim 14 along a first fold line 30. The first minor flap 16 is shown as being generally triangular in shape. It is contemplated, however, that the first minor flap may be shaped differently.
The first minor flap 16 forms a hinged opening or slot 32 to assist in securing the first and second major flaps 20, 22 to the first minor flap 16 when the container is in a closed position. The hinged opening 32 may be formed by, for example, a knife cut or a perforated cut. The hinged opening 32 is shown in its closed position in FIG. 4 and is shown in an open position in FIGS. 1-3 and 5. The hinged opening 32 receives a portion of the first and second major flaps 20, 22 when the container is in the closed position. (FIGS. 1-3 and 5). The hinged opening 32 may be shaped differently than the rectangular shape depicted in FIGS. 1, 2, 4 and 5. For example, the hinged opening of the first minor flap may be oval, circular, or other polygonal shapes. The hinged opening may have a length of from about 3⁄4 inch to about 3 inches according to one embodiment.
The hinged opening may be formed by having two pivoting pieces. In one embodiment of a two piece hinged opening, the hinges are located on opposing sides and each piece extends to the approximate middle of the opening to be formed. In this embodiment, each of the two pieces that form the hinged opening is about the same size. Alternatively, the two pieces that form the two piece hinged opening may be sized differently.
According to another embodiment, the first minor flap forms an opening to receive a portion of the first and second major flaps 20, 22. The opening may be shaped like the opening formed by the hinged opening 32 (i.e., rectangular). It is contemplated that the opening may be shaped differently, such as oval, circular or other polygonal shapes. It is also contemplated that the first minor flap may form a perforated cutout that is removable by the user to form an opening. The perforated cutout may be removed before or when placing the container in a closed position. The perforated cutout may be shaped the same as described above with respect to the opening of the first minor flap.
Similarly, the second minor flap 18 is integrally connected to the rim 14 along a second fold line 34 (FIG. 4) and located opposite of the first minor flap 16. The second minor flap 18 is shown as being generally triangular in shape. It is contemplated that the second minor flap may be shaped differently. It is also contemplated that the first and second minor flaps may be shaped differently.
The second minor flap 18 forms a hinged opening or slot 36 to assist in securing the first and second major flaps 20, 22 to the second minor flap 18 when the container is in a closed position. The hinged opening 36 may be formed by, for example, a knife cut or a perforated cut. The hinged opening 36 is shown in its closed position in FIG. 4 and is shown in an open position in FIGS. 1-3 and 6. The hinged opening 36 receives a portion of the first and second major flaps 20, 22 when the container is in the closed position (FIGS. 1-3 and 6). The hinged opening 36 may be shaped differently than the rectangular shape depicted in FIGS. 1, 3, 4 and 6. For example, the hinged slot of the second minor flap may be oval, circular, or other polygonal shapes.
According to another embodiment, the second minor flap forms an opening to receive a portion of the first and second major flaps 20, 22. The opening may be shaped like the opening formed by the hinged opening 36 (i.e., rectangular). It is contemplated that the opening may be shaped differently, such as oval, circular or other polygonal shapes. It is also contemplated that the second minor flap may form a perforated cutout that is removable by the user to form an opening. The perforated cutout may be removed before or when placing the container in a closed position. The perforated cutout may shaped the same as described above with respect to the opening of the second minor flap.
Referring back to FIG. 4, the first major flap 20 is integrally connected to the rim 14 along a third fold line 50. The first major flap 20 forms a first handle opening 52 that is adapted to form a handle when the container 10 is in a closed position. The first handle opening 52 may be formed by a knife cut or an absence of material. In such an embodiment, the user does not need to remove any material before forming the handle.
The first handle opening 52 may be formed by a perforated opening that is removed by a user. The perforated handle opening may be removed by punching out the material. Alternatively, the first opening may be formed by a hinged opening or slot that is movable to an open position. The perforated handle opening and hinged handle opening of the first major flap that are adapted to assist in forming a handle are referred herein as openable handle portions. The shape of the first handle opening 52 may be different than depicted in FIGS. 1 and 4, as long as the desired shape can function as a handle for carrying the container 10 in its closed position. Similarly, the perforated handle opening or hinged handle opening of the first major flap may be formed with similar shapes as the first handle opening 52.
The first major flap 20 also forms a first cutout or hook 54 and a second cutout or hook 56 at its respective ends. As shown in FIGS. 1-6, the first cutout 54 is adapted to receive and hold the hinged opening 32, while the second cutout 56 is adapted to receive and hold the hinged opening 36. The first cutout 54 and the second cutout 56 may be shaped differently than depicted in FIGS. 1-4.
It is contemplated that the first major flap 20 may have perforated and/or hinged openings or slots that are adapted to receive and hold a respective one of the first and second minor flaps 16, 18. It is also contemplated that the major flaps may be secured to the minor flaps with the use of protrusions from the major flap. The protrusions may extend outwardly from the remainder of the periphery of the major flap. It is contemplated that the protrusions may be made of different shapes to assist in securing to the minor flaps. The protrusions are typically located at or near opposing sides of the major flaps so as to secure respective minor flaps.
It is also contemplated that the first major flap may have a combination of cutouts, perforated openings, hinged openings or outward protrusions that are adapted to receive and hold a respective one of the first and second minor flaps 16, 18.
The first major flap 20 also includes a fold line 58 to assist in forming the container 10. The fold line 58 extends generally along a major axis of the first major flap 20. The fold line 58 may be formed by perforations or score lines. The fold line 58 may be formed by using, for example, hinge knives. The fold line 58 divides the first major flap 20 into a first section 20a and a second section 20b. 
The second major flap 22 is integrally connected to the rim 14 along a fourth fold line 70. The second major flap 22 forms a second handle opening 72 that generally aligns with the first handle opening 52 to form a handle when the container 10 is in a closed position. The second handle opening 72 may be formed by a knife cut or an absence of material. In such an embodiment, the user does not need to remove any material before forming the handle.
The second handle opening 72 may be formed by a perforated opening that is removed by a user. The perforated opening may be removed by punching out the material. Alternatively, the second opening may be formed by a hinged handle opening or slot that is movable to an open position. The perforated handle opening and hinged handle opening of the second major flap that are adapted to assist in forming a handle are referred herein as openable handle slots. The shape of the second handle opening 72 may be different than depicted in FIGS. 1 and 4, as long as the desired shape can function as a handle for carrying the container 10 in its closed position. Similarly, the perforated handle opening or hinged handle opening of the second major flap may be formed with similar shapes as the second handle opening 72.
The second major flap 22 also forms a first cutout or hook 74 and a second cutout or hook 76 at its respective ends. As shown in FIGS. 1-6, the first cutout 74 is adapted to receive and hold the hinged opening 32, while the second cutout 76 is adapted to receive and hold the hinged opening 36. The first cutout 74 and the second cutout 76 may be shaped differently than depicted in FIGS. 1-4.
It is contemplated that the second major flap 22 may have perforated and/or hinged opening or slots that are adapted to receive and hold a respective one of the first and second minor flaps 16, 18. It is also contemplated that the major flaps may be secured to the minor flaps with the use of protrusions from the major flap. The protrusions may extend outwardly from the remainder of the periphery of the major flap. It is contemplated that the protrusions may be made of different shapes to assist in securing to the minor flaps. The protrusions are typically located at or near opposing sides of the major flaps so as to secure respective minor flaps.
It is also contemplated that the second major flap may have a combination of cutouts, perforated openings, hinged openings or outward protrusions that are adapted to receive and hold a respective one of the first and second minor flaps 16, 18.
The second major flap 22 also includes a fold line 78 to assist in forming the container 10. The fold line 78 extends generally along a major axis of the second major flap 22. The fold line 78 may be formed by perforations or score lines. The fold line 78 divides the second major flap 22 into a first section 22a and a second section 22b. 
To close the container 10 from the open position of FIG. 4 to the closed position of FIG. 1, the minor flaps 16, 18 and the major flaps 20, 22 are folded upwardly and inwardly. According to one method, the major flaps 20, 22 are first folded upwardly and inwardly. As shown in FIG. 1, the major flaps 20, 22 meet in the approximate middle of the major axis of the container. The first handle opening 52 and second handle opening 72 generally align with each other in the closed position so as to form a handle for carrying the container 10. Depending on the embodiment, the first and/or second handle opening may need to be punched out by a user to form the handle. In the closed position, the first section 20a is generally parallel to and in the same plane as the rim 14, while the second section 20b extends upwardly from the first section 20a. A portion of the first section 20a rests on the rim 14 when the container 10 is in the closed position.
As shown in FIG. 1, the second section 20b of the major flap 20 is generally perpendicular to the first section 20a. Similarly, the first section 22a of the major flap 22 is generally parallel with the rim 14, while the second section 22b extends upwardly from the first section 22a. As shown in FIG. 1, the second section 20b is generally perpendicular to the first section 20a. It is contemplated that the first sections of the first and second major flaps may not necessarily be generally parallel to the rim 14 when the container 10 is in the closed position. It is also contemplated that the second sections of the first and second major flaps may not necessarily be generally perpendicular to their respective first sections when the container 10 is in the closed position.
According to this process, the first and second minor flaps 16, 18 are folded upwardly and inwardly. The hinged opening 32 of the first minor flap 16 is then folded and pressed over and into cutouts 54, 74 as depicted in FIGS. 1-3 and 5. Similarly, the hinged opening 36 of the second minor flap 18 is folded over and pressed into cutouts 56, 76 as depicted in FIGS. 1-3 and 6.
The polymeric container 10 of the present invention may comprise an alkenyl aromatic polymer. The term “alkenyl aromatic polymer” as used herein includes polymers of aromatic hydrocarbon molecules that contain an aryl group joined to an olefinic group with only double bonds in the linear structure, such as styrene, α-methylstyrene, o-methylstyrene, m-methylstyrene, p-methylstyrene, α-ethlystyrene, α-vinylxylene, α-chlorostyrene, α-bromostyrene, and vinyl toluene. Alkenyl aromatic polymers also include homopolymers of styrene (commonly referred to as polystyrene), copolymers of styrene and butadiene, and rubber-toughened polystyrene (commonly referred to as high impact polystyrene or HIPS). The alkenyl aromatic polymer may be an oriented polystyrene (OPS).
The polymeric container may be formed from polyolefins (e.g., polypropylene and high density polyethylene (HDPE)), polyethylene terephthalate (PET), polyvinyl chloride (PVC), and combinations thereof. The polymeric container may be made from a mineral-filled polymeric material such as, for example, talc or calcium carbonate-filled polyolefin. The polymeric container may be a foam such an alkenyl aromatic polymer described above or a polyolefin foam.
The polymeric container of the present invention is typically disposable, but it is contemplated that it may be reused at a future time. As shown in FIG. 4, the container 10 includes one compartment. It is contemplated that the containers may be formed of multiple compartments. Such containers are desirable for placing items (e.g., food items) in different compartments to prevent or inhibit commingling of items. For example, undesirable mixing of food items can corrupt the flavor and the consistency of the food items.
As discussed above, the polymeric container may be used with food items. A method of using such a container includes placing the food therein and then placing the container in a heating apparatus, such as a microwave, to heat the food. The container may contain solid food products. The container may be used for storage in the refrigerator and/or the freezer.
The polymeric container may be formed using conventional thermoforming (e.g., by pressure, vacuum or the combination thereof), or injection-molding processes. According to one method of thermoforming, pellets of a polymeric such as an alkenyl aromatic polymer resin and additives, if any, are added into an extruder. The pellets of the alkenyl aromatic polymeric resin and additives, if any, are melted to form a blend. The blend is extruded through a die to form an extruded sheet. The extruded sheet is thermoformed to a desired shape of a container.
The thickness of the polymeric container generally ranges from about 50 to about 150 mils, but is typically from about 70 to about 100 mils. The container may be opaque or a variety of colors or color combinations. If it is desired for the customer to ascertain the nature of the accommodated product and the condition thereof without having to open the container, the container may be at least generally transparent.
While a particular embodiment and applications of the present invention have been illustrated and described, it is to be understood that the invention is not limited to the precise construction and compositions disclosed herein and that various modifications, changes, and variations may be apparent from the foregoing descriptions without departing from the spirit and scope of the invention as defined in the appended claims.
