DESCRIPTION OF EMBODIMENT OF THE INVENTION

(16) With reference to FIGS. 1-11, and initially primarily to FIG. 1, the main components of an embodiment of a food container 100 of the present invention, showing an order of assembly, are shown and will be described. A sealing layer 120 connects to and covers the bottom of a lid 110. Internal compartments 130 fit within a base unit 140 and can be rearranged as needed. The lid 110 with sealing layer 120 engaged (shown in FIG. 5) is placed on to the base unit 140, covering a base unit rim 140a as well as internal compartment rims 130a (FIG. 6). A ring assembly 150 slips onto the base unit 140 from the bottom and stops at the hem of the base unit rim 140a while a ring engaging groove 150d (shown in FIG. 1) catches on a base unit interference nodule 140c to avoid accidental slipping of the ring assembly 150 when not engaged. A ring clamp 150b can then be engaged to securely fasten the lid 110 containing the sealing layer 120 to the base unit 140.

(17) The base unit 140 may contain internal compartments 130 that are of different shapes or sizes of lengths and widths and can be removed and/or arranged in an array of different configurations and locations within the base unit 140. A small sample set of different configurations is illustrated in FIG. 8A, FIG. 8B and FIG. 8C.

(18) In an exemplary method of using the food container, when preparing food and/or beverages to be stored/transported in the container or after using the food container (e.g., after eating), one or more internal compartments 130 of the same and/or different configurations are arranged in the base unit 140 in any desired position(s) as long as open end 132 (FIG. 5) is facing upward in base unit 140 and the lid 110 with sealing layer 120 is secured to the base unit 140 (with the ring clamp 150b securely fastening the lid 110) as shown in FIG. 6 so that a perimeter seal, as well as a seal between movable/removable/reconfigurable internal compartments 130, is provided to maintain a leak-proof seal inside and out. When ready to eat, remove one or more internal compartments 130, and/or clean the one or more internal compartments 130, the ring clamp 150b is unfastened from the lid 110 and the lid 110 with sealing layer 120 is removed from the base unit 140. The one or more internal compartments 130 may be accessed (e.g., for eating/drinking the contents, removing one or more internal compartments 130, and/or cleaning the one or more internal compartments 130). When ready to re-use the food container, one or more of the same and/or different internal compartments 130 as those used previously are arranged in the base unit 140 in any desired position(s) and the above process is repeated.

(19) Cross-sectional side views of the food container are shown in FIG. 4, FIG. 5 and FIG. 6, illustrating the separation and connection of the sealing layer 120 to the lid 110, and the securing of a lid assembly 112 (e.g., the lid 110 and connected sealing layer 120) to the base unit 140 with the ring clamp 150b.

(20) In reviewing the lid assembly 112 including the sealing layer 120 and the lid 110, FIG. 4 identifies an engaging groove 110a along a periphery and underside of the lid 110 and a lip 120a of the sealing layer 120. The lip 120a fits into the engaging groove 110a (FIG. 5). The length and/or width of the sealing layer 120 may be shorter than the distance between the engaging grooves 110a. Therefore, the sealing layer 120 may stretch so that the lip 120A fits into the engaging groove 110a to provide enough pushing force so that the sealing layer 120 will remain intact with the lid 110 when removing from and inserting into the base unit 140. It should be noted that this pushing force can also be accomplished by other factors (not shown) such as, but not limited to, an interference nodule on the lip 120A that protrudes out to provide enough pushing force when placed into the engaging groove 110a. However, the sealing layer 120 can be easily removed from the engaging groove 110a by hand for purposes of cleaning.

(21) The cross-sectional view in FIG. 6 illustrates the method of producing a leak-proof seal between internal compartments 130 as well as at the rim 140a of the base unit 140.

(22) The base unit 140 may be slightly narrower at a bottom 142 than at its rim 140a or top 144, thus allowing for the ring assembly 150 to slide up from the bottom 142 of the base unit 140 and fit securely along sides 146 due to a lateral outward pushing force from the sides 146 of the base unit 140 once the ring assembly 150 reaches its stopping point at the hem of the base unit rim 140a. For a more secure fastening, the base unit 140 may contain the interference nodule 140c that catches the ring engaging groove 150d, as shown in FIG. 1. The ring engaging groove 150d caught by the interference nodule 140c keeps the ring assembly 150 connected to the base unit 140 without slipping off. However, the ring assembly 150 can be easily slid back down and removed from the base unit 140 for cleaning. With the ring assembly 150 at the hem of the base unit rim 140a, the ring clamp 150b can securely fasten the lid assembly 112 to the base unit 140. The engaged ring clamp 150b applies pressure on lid 110, which in turn presses the sealing layer 120 down on the internal compartment rims 130a as well as the base unit rim 140a.

(23) The sealing layer 120 is a flexible material, such as silicone, and may consist of rods 120c, hexagons or other shapes and vary in durometers for added strength and stability to this flexible sealing layer 120. When in contact with the base unit 140 while the ring clamp 150b is engaged, a seal cover 120b firmly presses down on the base unit rim 140a, removing entry and/or exit points for fluid to enter or escape. Furthermore, because the sealing layer 120 is a flexible layer with a particular range of stability and durometer, its seal cover 120b presses down over any internal compartment rims 130a (as depicted in FIG. 6), no matter the width, length, location or quantity that are included within the base unit 140. This pressure cuts off any possible exchange of food or fluid between internal compartments 130 to each other or the base unit 140.

(24) To further explain the leak-proof seal between internal compartments 130 and base unit 140, FIG. 7 shows an enlarged cross-sectional view of where the seal cover 120b meets the internal compartment rims 130a and the base unit rim 140a. The distance between where a top engagement section 150e of the engaged ring clamp 150b contacts a top 114 of the lid assembly 112 (or the top 114 of the engaged lid assembly 112) and the internal compartment rims 130a and/or the base unit rim 140a is slightly shorter than the height of the lid assembly 112, which allows for the seal cover 120b to exert a pushing force over and on the internal compartment rims 130a and base unit rim 140a when the ring clamp 150b is engaged, producing a leak-proof seal between internal compartments 130. The sealing function described provides a method of sealing internal compartments with a sealing layer, a method that does not require the internal compartments to have or use their own lids.

(25) Referring to FIG. 5 and FIG. 6, when the ring assembly 150 is connected to the base unit 140, the ring 150a of the ring assembly 150 contains a top portion or lid guide 150c protrudes above any internal compartment rims 130a and/or the base unit rim 140a. The dimensions of the lid guide 150c allow the lid assembly 112 to fit directly over the hem of the base unit rim 140a to ensure proper location of the lid 110, and, thus, the seal cover 120b over the base unit 140 and any internal compartments 130 before the ring clamp 150b is engaged.

(26) FIG. 6 illustrates a base bevel 140b, an additional location guide, that helps to keep any internal compartments positioned properly along the sides of the base unit 140. When and/or if an internal compartment 130 is positioned along the side walls within the base unit 140, the angled base bevel 140b comes into contact with the internal compartment bevel 130b making it slide to the floor of the base unit 140. This ensures the internal compartment 130 is positioned away from the side walls of base unit 140 so that the internal compartment rim 130a avoids contact with and/or overlapping of the base unit rim 140a allowing the sealing layer 2 to engage properly, as described above.

(27) It should be known that the ring assembly 150 is the example depicted in these illustrations. However, other types of clamps or secure measures that exert a force between the lid and the base unit could be used in addition to or instead of the ring assembly 150 and have a similar effect.

(28) In addition the sealing layer 120 being preferably made of silicone, the food container components are preferably made of stainless steel of varying gauges for a combination of strength and durability, yet still light enough in weight. The base unit 140, internal compartments 130 and lid 110 could be a single-walled stainless steel, but can also take a more insulated approach, such as having a dual-wall. In this scenario, air might be removed in between the walls and an insulating material and spacer support such as a cork layer may also exist.

(29) While the likely materials of the food container 110 are stainless steel, it should be known that certain plastics, wood, silicone, or other materials may be used to provide a similar resulting product. However, from a current health and food safety standpoint, the food container 100 is intended to also function in a way that ensures no plastic resin touches food contents within the base unit 140 or internal compartments 130. Therefore, for the purposes of this description, the base unit 140 and the internal compartments 130 are made of a food-grade stainless steel.

(30) Accordingly, it is important to note that the sealing layer 120 is not only a leak-proof layer, but also acts as a protection layer from food touching the lid 110. Therefore, the lid 110 may be of plastic material which can be used to provide color, patterns or even transparency to the food container 100. The lid 110 may also be formed from other materials such as wood, offering an additional function as a cutting board, serving tray or plate. Alternatively, similar to the internal compartments 130, the lid 110 may be formed from stainless steel. Stainless steel components might be powder-coated to provide exterior colors or patterns as well as an additional gripping benefit and durability. Likewise, the ring assembly 150 can offer a number of ways for color, patterns and other forms of personalization.

(31) The lid 110 also has space-saving functions. Referring to FIG. 9, the base unit 140 can rest on the lid 110, providing a more secure base unit 140 while eating, and also takes up less space. FIG. 10 shows how the base units 140 and internal compartments 130 have wider rims than their bottoms so they can nest within themselves when storing away/not in use. Further, FIG. 11 illustrates how a base unit 140 of the food container 100 can stack on top of the lid 110 of another food container 100 with the lid 110 intact.

(32) Because of the leak-proof function of sealing layer 120, the internal compartments 130 do not use their own lid when sealed in the base unit 140. However, for storing purposes, internal compartments 130 may use their own independent lid (not pictured in the figures) that can be put in place when storing in the refrigerator, freezer, pantry or other times when in use without the base unit 140.

(33) The hem of the base unit rim 140a was described earlier to provide a stopping point for the ring assembly 150. With the removal of the ring assembly 150, the hem of the base unit rim 140a can also be a stopping point for a utility ring (not shown in figures) that might offer a number of different accessories: handles, carabiner, or other clips and clamps. These accessories might be part of the utility ring or pieces that clip or fasten to the utility ring. As an example, the addition of handles turns the base unit 140 into an easy to hold and transfer piece of cook ware.

(34) The above figures may depict exemplary configurations for the invention, which is done to aid in understanding the features and functionality that can be included in the invention. The invention is not restricted to the illustrated architectures or configurations but can be implemented using a variety of alternative architectures and configurations.
