Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are therefore not to be considered as limiting, unless the claims expressly state otherwise.

(14) A stackable and nestable food containment system 100 is referenced in FIGS. 1-10. As referenced in FIG. 1, the stackable and nestable food containment system 100, hereafter system 100, provides a plurality of tray members 102 structured to hold edible substances, and a plurality of lids 200 that fit over the top of the tray members 102 to seal and reclose the tray members 102 as the edible substances are removed. Each empty tray member 102 may be stackable on an adjacent lid 200, or arranged for shipment in nested fashion.

(15) When stacked, the tray members 102 are inhibited from laterally shifting due to grooves 118a, 118b, 118c, 208a, 208b, 208c that integrate into the bottom surface 106 of the tray members 102 and the exterior surface 204 of the lids 200 (FIG. 2). The grooves 118a, 118b, 118c, 208a, 208b, 208c are substantially matching to create an interlocking relationship between tray member 102a and corresponding lid 200a. When the tray members 102 are covered with the lids 200, and in a stacked arrangement, spillage is also inhibited.

(16) In some embodiments, at least one barrier 112a, 112b traverses the cavity 116 of each tray member 102 to form three separate compartments 114a, 114b, 114c. The compartments 114a, 114b, 114c serve to segregate different edible substances, and also create an interlocking arrangement between tray members 102 in a nested configuration. When nested, the three compartments 114a, 114b, 114c also inhibits lateral shifting or easy separation. The tray members 102 and the lids 200 are fabricated from a microwavable and dishwasher safe material.

(17) As referenced in FIG. 3, the system 100 comprises a plurality of tray members 102. The tray members 102 may include food take-out trays or other containers designed for storing and eating edible substances. In some embodiments, the tray members 102 may be microwaveable and machine washable to enable reusability and enhanced functionality. The tray members 102 may be at least partially transparent and flexible. Suitable materials for the tray members 102 may include, without limitation, a polymer, a low density polyethylene, a polystyrene, polypropylene, stainless steel, and wood.

(18) As illustrated in FIG. 4, each tray member is defined by a tray exterior bottom surface 104, a tray interior bottom surface 106, a tray sidewall 108 that terminates at a tray edge 110, and a cavity 116. The tray sidewall 108 may extend from the periphery of the tray bottom surfaces 104, 106, forming a generally square shape. Though in other embodiments, the tray sidewall 108 may form a rectangular, circular, or other elongated shape. The tray edge 110 may include a ridge that runs along the length of the tray edge 110.

(19) The tray exterior and interior bottom surfaces 104, 106 are generally flat. Though in some embodiments, the bottom surfaces 104, 106 may be concave. The tray exterior and interior bottom surfaces 104, 106 are defined by at least one first groove 118a, 118b, 118c. The first groove 118a, 118b, 118c may be protruding or recessed into the tray bottom surfaces 104, 106, depending on the interior or exterior side of the tray bottom surface 104, 106.

(20) As FIG. 5 illustrates, the first groove 118a, 118b, 118c forms a generally continuous loop shape. Though the first groove 118a, 118b, 118c may follow any number of patterns, depths, shapes, and textures. In one exemplary embodiment, a series of first grooves 118a, 118b, 118c form a concentric pattern, with one groove running in a loop around another, and another, etc.

(21) Looking now at FIG. 6, the tray members 102 may further be defined by at least one barrier 112a, 112b that is disposed to traverse the cavity 116 of the tray members 102. The barrier 112a, 112bs form multiple compartments 114a, 114b, 114c for segregating the edible substances in the cavity 116. In one embodiment, each tray member 102 has three separate compartments 114a, 114b, 114c for segregating different edible substances and for creating an interlocking arrangement between tray members 102.

(22) For example, without limitation: a meat can be placed in a first compartment 114a; a vegetable in a second compartment 114b; and a jelly in a third compartment 114c. Though in other embodiments, liquids may also be placed in the compartments 114. Further, the compartments 114a, 114b, 114c may be sized differently, with a large first compartment 114a and smaller second and third compartments 114b, 114c.

(23) In another embodiment, the compartments 114a, 114b, 114c from different tray members 102 fit into each other in a nested arrangement. This is possible because of the similar shape and positioning of compartments 114a, 114b, 114c for each tray member 102. Further, the proximal arrangement of compartments 114a, 114b, 114c relative to each other forms a substantially solid surface that is adaptable to stacking tray members 102, and creates additional stability in the stacked arrangement (See FIG. 1).

(24) Turning now to FIG. 7, the system 100 further comprises a plurality of lids 200 that are adapted to operate with the tray members 102. In some embodiments, the lids 200 may be generally flat and impermeable. The lids 200 may also be flexible and at least partially transparent. Though the physical characteristics may be altered to accommodate different types of edible substances and tray members 102.

(25) Suitable materials for the lids 102 may include, without limitation, a polymer, a low density polyethylene, a polystyrene, polypropylene, stainless steel, and wood. The lids 102 may also be flexible to enable conformance to the tray edge 110 of the tray members 102.

(26) As illustrated in FIG. 8, the lids 200 are defined by a lid interior surface 202, a lid exterior surface 204, and a lid edge 206. The lid edge 206 forms a perimeter to the lid 200 and is shaped and dimensioned to detachably couple to the tray edge 110. A tab 210 may extend from one corner of the lid edge 206 to facilitate removal of lid 200 from tray member 102.

(27) In one embodiment, the lid edge 206 is a depression that runs along the length of the lid edge 206. The lid edge 206 may form a friction fit, or snap-fit relationship with the tray edge 110. The edges 110, 206 form a sealed relationship to maintain freshness of the edible substances contained in the cavity 116.

(28) Similar to the bottom surfaces 104, 106 of the tray members 102, the lid interior and lid exterior surfaces 202, 204 are defined by at least one second groove 208a, 208b, 208c. The second groove 208a, 208b, 208c substantially matches the shape and size of the first groove 118a, 118b, 118c in the bottom surfaces 104, 106 of the tray members 102a, 102b. In one embodiment, a series of second grooves 208a, 208b, 208c form a concentric pattern, with one groove running in a loop around another, and another.

(29) The second groove 208a, 208b, 208c is configured to detachably couple to a correlating first groove 118a, 118b, 118c in the tray exterior bottom surface 104. In one embodiment, the second groove 208a, 208b, 208c of the lid 200 forms a generally continuous loop shape. Though the second groove 208a, 208b, 208c may follow any number of patterns, depths, shapes, and textures.

(30) The grooved edge 206 of the lid 200a are configured to detachably mate with the tray edge 110, and thereby enable the lid 200a to cover the tray member 102a for preventing spillage of edible substances. FIG. 9 illustrates a compartment 114a of the tray member 102 sized to engage the lid shown in FIG. 10. The compartments 114a-c match similar shaped sections of the lid 200 to create a seal. The grooves 118a-c, 208a-c from both tray member 102 and lid 200 also match in alignment to form a stable stacked arrangement.

(31) Thus, when the tray member 102a is sealed, the edible substance in the cavity 116 is prevented from spilling, and also leakage of food between each compartment 114a, 114b, 114c is prevented. Furthermore, covering the tray member 102a with the lid 200a enables multiple tray members 102 to be arranged in a stacked configuration.

(32) In this stacked configuration, the first groove 118a, 118b, 118c on the bottom tray surfaces 104, 106 and the second groove 208a, 208b, 208c on the lid exterior surface 204 can align and mate. In one embodiment, the interlocking relationship between grooves 118a, 118b, 118c, 208a, 208b, 208c works to inhibit lateral shifting of a first tray member 102a relative to a similar second tray member 102b in a second direction substantially perpendicular to the first direction and substantially parallel to the exterior bottom surface 104 of the first tray member 102a.

(33) When the lids 200 are removed from the tray members 102, the tray members 102 and lids 200 may be arranged separately in a nested configuration for efficient storage and shipping. In the nested configuration, the compartments 114a, 114b, 114c for each tray member 102 fit into each other. Further, the at least one first groove 118a, 118b, 118c of the tray members 102 and the at least one second groove 208a, 208b, 208c of the lids 200 form correlating relationships that enable separate nesting of the tray members 102 and the lids 200 (FIGS. 9 and 10).

(34) In operation, a user may place edible substances in each of the three compartments 114a, 114b, 114c of the tray members 102. The lids 200 may be snapped onto the tray edge 110 to seal the edible substance in the cavity 116 of the tray members 102. Multiple tray members 102 may be stacked with the first groove 118a, 118b, 118c from the tray exterior bottom surface 104 mating with the second groove 208a, 208b, 208c in the lid exterior surface 204. The tray members 102 may then be carried in a stacked configuration with no lateral shifting between tray members 102 or spillage from the cavity 116 of the tray members 102. Further, multiple empty tray members 102 may be nested into each other, with the compartments 114a, 114b, 114c aligning to receive each other.

(35) These and other advantages of the invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims and appended drawings.

(36) Because many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
