While the invention is susceptible to various modifications and alternative forms, the specific embodiments thereof have been shown by way of example in the figures and will be described herein in detail. However, it should be understood that it is not intended to limit the invention to the particular forms described, but on the contrary, the intention is to cover all modifications, equivalents and alternatives that fall within the spirit and scope of the invention as defined by of the appended claims.

Description of the Illustrative Modes With reference to Figures 1-5, a container (e.g., a dish 10) that will be used in one embodiment of the present invention is shown. The plate 10 is used with a second plate 110 (see Figures 7 and 8) it could be substantially the same, or alternatively, identical to the plate 10 to form a container assembly that can be releasably closed. It is contemplated that other container assemblies could be formed in addition to those that use plates.

For example, container assemblies could be formed, but are not limited to, the use of plates, bowls, trays, buckets, family-size containers and of single service, refractory tableware of family size and single service and combinations thereof. A combination is a bowl and a plate that forms a container assembly. The remainder of the application will discuss a container and container assemblies with respect to the dishes although it is recognized by one of ordinary skill in the art that other container assemblies, such as those discussed above, could be formed. The height and shape of the container assembly could vary from those shown without departing from the scope of the invention. For example, the container assemblies of Figures 7a and 14a as will be discussed, are shown to be generally circular. It is contemplated that container assemblies and containers used herein could be of other shapes, such as rectangular, square, hexagonal, octagonal, other polygonal shapes and non-polygonal shapes such as ovals. The container assemblies of the present invention are normally used with respect to the food, although they could be employed in other applications such as with medical, cosmetic and other products. The food container assemblies could be used for the service, storage, preparation and / or reheating of the food. With reference to Figures 1-2, the container 10 it includes a continuous body portion 12 and a continuous flange 14 that surrounds and protrudes laterally outwardly of the body portion 12. The body portion 12 includes a lower portion 16 and a continuous side wall 18 that surrounds and projects upwardly. and outwardly from the lower part 16. It is contemplated that the side wall could protrude only upwards from the lower part 16 or even that it could protrude upwards and inwards from the lower part 16. It is also contemplated that the flange does not It could be continuous, although you want it to be continuous. Referring specifically to Figure 2, the continuous flange 14 includes a plurality of edges 20 that project generally upward therefrom. The plurality of edges 20 is spaced around the general periphery of the container 10 and helps form the container assembly that can be releasably closed. The orientation of the plurality of edges 20 creates a pattern that is generally perpendicular to the direction of the flange 14. More specifically, the orientation of the plurality of edges 20 could create a pattern that is perpendicular to the direction of the flange 14. In a radial configuration with a pattern that is perpendicular to the direction of the flange, each of the plurality of edges 20, if extended inward, it would pass through the general center of the plate.

However, the plurality of edges 20 could be formed in different patterns that are shown in Figure 2 with respect to the flange 14 (for example, in the diagonal direction). It may be desirable to form the plurality of edges 20 in a decorative pattern for aesthetic reasons. This decorative feature could help to "hide" or disguise the releasable closure feature in the container 10. The container 10 of Figure 2 has exactly 60 edges formed in the continuous flange 14. It is contemplated that the number of edges could vary from which is shown in Figure 2. For example, a container could have approximately 3 to 10 edges. A container could have approximately more than 20 or approximately 40 edges, and could even have up to or more than 120 edges. The desired number of edges formed in the container will often vary depending on factors such as the size or shape of the container assembly, the type and thickness of the material (s) of the container assembly, and the desired retention strength. of the container assembly. The desired strength of retention or clamping is a function of factors such as the weight of the product placed in the container assembly and its known use. With reference to Figures 3-5, the plurality of edges 20 is shown in greater detail. Specifically, a cross-sectional view of Figure 3 shows two adjacent edges projecting upwards from the continuous flange 14. Figure 3 represents a first edge 20a and a second edge 20b with a space 22 that is formed between them. The first edge 20a of Figure 3 comprises a generally planar surface 24 joining two side walls 26, 28. The first edge 20a is shown to be generally perpendicular to the plane of the remainder of the continuous flange 14. Specifically, the first edge 20a it is shown that it is generally perpendicular to the CC plane formed along the remainder of the rim 14 in Figure 3. More specifically, the edge could be perpendicular to the plane of the rest of the rim. The side walls 26, 28 are spaced apart from each other and are shown to be generally perpendicular to the CC plane of the remainder of the flange 14. However, the side walls 26, 28 do not necessarily have to be generally perpendicular or perpendicular to the rest of the flange 14. Similarly, the second edge 20b of the Figure 3 comprises a generally planar surface 30 joining two side walls 32, 34. The second edge 20b is also shown to be generally perpendicular to the plane CC of the remainder of the flange 14. The side walls 32, 34 are separated from each other and are shown which are generally perpendicular to the CC plane of the rest of the flange 14.

In order to provide an improved closure container assembly, at least one of the edge side walls could have a slanted cut. This optional undercut that is formed in the side edge wall engages with a similar slant cut in a corresponding space formed between the adjacent edges of the second container when the container assembly is formed. This is discussed below in further detail with respect to Figures 7-8. For example, in Figure 3, the optional biased cuts 26a, 28a are formed in the respective side walls 26, 28. The shape and size of the biased cut will vary depending on factors such as the size or shape of the mounting container, the type and thicknesses of the container assembly material (s), and the desired retention resistance of the container assembly. The desired strength of retention or clamping is a function of factors such as the weight of the product placed in the container assembly and its known use. The number of biased cuts formed in the side walls of the edge, if any, is a function of factors such as the desired resistance against leakage, the type of the closing mechanism, the degree of manufacture of the container assemblies and the type and the thicknesses of the material (s) used to form the container assemblies. For example, if the mounts of If the container were made of a first material that had a higher coefficient of friction than a second material, then the processed container of the first material will probably need less slanted cuts in its side walls than the same container made with the second material so that it has the same retention resistance. The number of biased cuts used is also a function of the use placement of the container assembly, which includes the retention resistance thereof. It is contemplated that the edges could have side walls without biased cuts or at least one biased cut (e.g., the first edge 20a with the optional skewed cuts 26a, 28a in Figure 3). It is also contemplated that some edges within the same container could not have skewed cuts, while other edges could have one or more skewed cuts. With reference to Figures 4 and 5 the adjacent edges 36, 38 of a portion of the flange 14 are shown in greater detail. In Figure 4, the top view of the edges 36, 38 shows that the edges 36, 38 become generally tapered inward toward the center of the container. Figure 4 also shows a generally flat area 36a of the edge 36 and a generally flat area 38a of the edge 38. To improve the seal of the mounting container, the generally planar areas 36a, 38a could make contact with flat areas of similar size formed in the respective spaces between the adjacent edges of a second container forming the container assembly. An example of a flat area of similar size formed in the space between the adjacent edges is shown in Figure 4 with the generally planar area 40. Figure 5 shows the adjacent edges 42, 44 with the respective generally planar areas 42a, 44a. The edges 42, 44 are separated with a generally flat area 46 that is formed between the generally planar areas 42a, 44a. To keep the games in radial designs (eg, oval or circular), the generally flat areas could grow proportionally with the diameter (ie, increase in size as the distance increases from the center of the container) . For example, in Figure 5, the width Wl of the generally flat area 42a could be smaller than the width W2. For example, with containers of rectangular shape, the size of the generally flat areas usually remains constant as the distance increases from the center of the container. It is contemplated that this area of the edges could be dimensioned and configured differently from that shown in Figures 4 and 5. It is contemplated that the shape and size of the plurality of edges 20 could vary from those shown in Figures 2-5. It is preferred that the plurality of edges be configured and dimensioned to minimize the stacking height of the containers used to form the container assemblies. It is desirable to minimize the stacking height of the containers to (a) decrease transportation and packaging costs, and (b) provide space efficiency in the retail and consumer facilities. It is also desirable to maximize the holding strength of the container assembly. The desired retention resistance is often a balance between easy fabrication of the container assembly for the consumer to open and close it, while still preventing or preventing inadvertent opening of the container assembly. It is contemplated that the shapes or configurations protruding upward could be differently than the edges shown in Figures 2-5 and 11-13. For example, the configurations protruding upwards could be a plurality of round, oval, square or polygonal shapes or configurations. It is contemplated that many shapes and sizes could be configured through the protruding shapes that are used in the present invention. With reference to Figures 5 and 6, an optional shape or configuration of seal 50 formed in the flange 14. In Figure 6, the optional shape or configuration of seal 50 is located away from edge 52 with respect to the center of container 10. In other words, optional seal configuration 50 is located further away from the center of container 10. that of the edge 52. The optional seal configuration 50 in conjunction with the corresponding optional seal configuration in another container (not shown), together with the closing edges of the container assembly, help to prevent or prevent the material from escaping or that enters the container assembly. The optional seal configuration is especially useful to prevent or prevent product leakage that could happen due to tolerances within the manufacturing process. In order to provide an efficient seal, the height Hl of the optional seal configuration 50 must be at least half the height H2 of the edge. However, the optional seal configuration could be located inboard of the edges, so that the seal is formed closer to the center of the container assembly when compared to the edges that can be releasably closed. For example, in Figures 16a and 16b, a container 510 includes a plurality of edges 520 and also includes an optional seal configuration 550. In Figures 6 and 16b, the optional seal configuration 550 is located inwardly of the plurality of stamps. 520 edges with with respect to the center of the container 510. The optional seal configuration 550 in conjunction with a corresponding seal configuration in another container (not shown), together with the closing edges of the container assembly, help to prevent or prevent the material from escape or enter the container assembly. The optional seal configuration could be formed in a variety of ways, including a generally conical shape. A container assembly 100 according to one embodiment of the present invention is shown in Figures 7a, 7b. The container 100 comprises the first container 10 and a second container 110. In one embodiment, the second container 110 is substantially configured in the same manner as the first container 10. Alternatively, the second container 110 could be identical to the first container 10. It may be desirable to have containers configured in the same way to reduce consumer waste when the upper container or lid is not used. As discussed above, the container assembly could be formed with the first and second containers different than the dishes. The container assembly 100 of Figures 7a, 7b could be formed in accordance with a method by providing the first container 10 and the second container 110. The second container 110 includes a continuous body portion. 112 and a continuous flange 114 surrounding and projecting laterally outward from the body portion 112. Similarly, the first container 10 as discussed above, includes the continuous body portion 12 and the surrounding continuous flange 14. and protrudes laterally outwardly from the body portion 12. Both of the shoulders 14, 114 include a respective plurality of edges with spaces therebetween (not shown in Figures 7a, 7b). Each of the plurality of edges could be configured and sized similarly to the edges 20 shown above in Figures 2-5. Each of the plurality of edges generally protrudes upward therefrom (i.e., in a direction away from the continuous body portion). The second container 110 is turned 180 degrees relative to the first container 10, so that the containers 10, 110 are generally aligned and the flanges 14, 114 are adjacent to each other. This inverted position of the container 110 relative to the container 10 is shown in Figure 7a. To place the edges within the respective spaces, the container 110 may have to be rotated in a light manner, so that the edges are displaced (ie, the edges and spaces are aligned). It is desirable that the consumer be able to assemble the containers to form a container assembly of the present invention. With reference to Figure 8, the adjacent edges 120a, 120b of the container 110 are placed within the respective second spaces 22a, 22b of the container 10 and the edges 20a, 20b of the container 10 are placed within the respective spaces 122a, 122b, so that the container assembly 100 can be closed releasably. To place the edges within the respective spaces, the container 110 may have to be rotated lightly, so that the edges are offset (ie, the edges and spaces are aligned). Figure 8 also depicts the interference zones 124a, 124b formed between the first edge 20a and the space 122a created between the edges 120a, 120b of the container 110. The strength of this lock that can be immobilized is a function of many variables such as the number of protruding edges, the height of these edges, if skewed cuts are included, the size of the contact areas, the necessary clearance between the spaces and the edges, and the type and thickness of the material (s) used for form the container assemblies. To improve the degree of closure of the container assembly, as discussed above, an optional sealing feature or configuration could be added. With reference to Figures 9-10, a container (e.g., plate 210) includes a continuous body portion 212 and a continuous flange 214 that surrounds and protrudes laterally outwardly from the body portion 212. The body portion 212 includes a lower portion 216 and a side wall. continuous 218 that projects around and protrudes upwards and outwards from the lower portion 216. It is contemplated that the side wall could only project upwardly from the lower portion 216 or even project upwardly and inwardly from the lower portion 216. it contemplates that the flange could not be continuous, although it is preferred that it be continuous. With reference to Figures 10 and 11, the continuous flange 214 includes a plurality of edge assemblies 220 that generally project upward therefrom. The plurality of edge assemblies 220 is spaced around the general periphery of the container 210 and helps form the container assembly that can be releasably closed. The orientation of the plurality of edge sets 220 creates a pattern that is generally parallel or generally concentric with the general direction of the flange 214. In other words, each of the plurality of edge sets 220, if extended outward, does not would be so close to the general center of the container 210. The plurality of edge sets 220 is located in the opposite direction of the plurality of edges 20 in the Figures 2-5. However, the plurality of edge sets 220 could be formed in different patterns from those shown in Figure 10 with respect to the rim 214 (e.g., diagonally). It may be desirable to form the plurality of edge assemblies 220 in a decorative pattern for aesthetic reasons. This decorative feature could help to "hide" or disguise the closure feature releasably in the container 210. The container 210 of Figure 10 has exactly 60 sets of edges formed in the continuous flange 214. As will be discussed in more detail below, each of the plurality of edge assemblies 220 has a first set of edges on a raised portion and a second set of edges on a portion reduced It is contemplated that the number of edge sets could vary from that shown in Figure 10. For example, a container could have approximately 2 to 30 edge sets. A container could have approximately more than 40 or about 80 edge sets, and could even have up to or more than 120 edge sets. The desired number of edges formed in the container will often be a function of factors such as the size or shape of the container assembly, the type and thickness of the material (s) of the container assembly and the desired strength of the container.

Retention of the container assembly. The desired resistance of retention could be a function of factors such as the weight of the product placed in the container assembly and its known use. With reference to Figures 11-13, two adjacent sets of edges are shown in greater detail. The number of edges in the assembly varies in Figures 11 and 12 depending on whether the edges are located in a recessed area or in an elevated area formed in the rim 214. For example, in Figures 11 and 12, the recessed area 240 has a first edge 242 and a second edge 244 with the spaces 246, 248 and 250. However, the raised area 260 of Figures 11 and 12 has a first edge 262, a second edge 264 and a third edge 266 with the edges 266. spaces 268, 270 between them. Each of the edges of Figures 11 and 12 protrudes upwardly from the continuous flange 214. With reference specifically to Figure 13, a cross-sectional view of the recessed area 240 is shown and includes the edges 242, 244. A cross-sectional view of the raised area 260 (not shown) would represent three edges. The first edge 242 of Figure 13 comprises a generally planar surface 288 joining two side walls 290, 292. The first edge 242 is shown to be generally perpendicular to the plane of the remainder of the continuous flange 214. Specifically, the first edge 242 is shown to be generally perpendicular to the plane DD formed along the remainder of the rim 214 in Figure 13. More specifically, the edge could be perpendicular to the plane of the remainder of the rim. The side walls 290, 292 are spaced apart from each other and shown to be generally perpendicular to the plane DD of the remainder of the rim 214. However, the side walls 290, 292 do not necessarily have to be generally perpendicular or perpendicular to the remainder of the rim 214. Similarly, the second edge 244 of the Figure 13 comprises a generally planar surface 298 joining two side walls 300, 302. The second edge 244 is also shown to be generally perpendicular to the plane DD of the remainder of the flange 214. The side walls 300, 302 are separated from each other and shown which are generally perpendicular to the plane DD of the remainder of the flange 214. In order to provide an improved closure container assembly, at least one of the edge side walls could have an optional undercut. As discussed above, this biased cut formed in the edge side wall engages with a similar biased cut in the spaces formed between the adjacent edges when the container assembly is configured. For example, in Figure 13 the optional skewed cuts 290a, 292a are formed in the respective side walls 290, 292. The size and shape of the biased cut will vary depending on factors such as the size or shape of the container assembly, the type and thickness of the material (s) of the container assembly and the desired retention resistance of the container assembly. The desired resistance of retention could be a function of factors such as the weight of the product placed in the container assembly and its known use. As discussed previously, the number of skewed cuts formed in the edge sidewalls, if any, is a function of several factors. It is contemplated that the edges could have side walls without biased cuts or at least one biased cut (e.g., the first edge 242 with the optional skewed cuts 290a, 292a in Figure 13). It is also contemplated that some edges within the same container could not have skewed cuts, while other edges have one or more skewed cuts. With reference to Figure 12, the raised and recessed areas 240, 260 have a plurality of edges with generally planar areas. For example, edge 242 includes a top surface or generally planar area 242a. Similarly, edge 264 includes a top surface or generally planar area 264a. To improve the seal of the container assembly, the generally planar areas 264a, 242a may contacting flat areas of similar size that are formed in the spaces configured between the adjacent edges of a second container forming the container assembly. An example of a flat area of similar size formed in a space is shown in Figure 12 with space 246. As shown in Figure 12, a generally planar area 282 is formed between adjacent sets of edges (i.e. raised and lowered portions) to aid in releasably locking or closing the container assembly. It is contemplated that this area of the edges could be sized and configured in a manner different from that shown in Figures 11-13. It is contemplated that the numbers of edges in a set of edges could vary from that shown in Figures 11 and 12 (two edges in the recessed areas and three edges in the raised areas). It is contemplated that the shape and size of the plurality of edges 220 could vary from what is shown in Figures 10-13. It is preferred that the plurality of edges be configured and dimensioned to minimize the stacking height of the containers. It is desirable to minimize the stacking height of the containers to (a) decrease transportation and packaging costs, and (b) provide space efficiency in the retail and consumer facilities. It is also desirable to maximize the Retaining resistance of container assembly. The desired retention resistance is often a balance between making the container assembly for the consumer to open and close it easily, while still preventing or preventing inadvertent opening of the container assembly. Referring specifically to Figure 12, an optional shape or configuration of seal 350 formed on rim 214 is shown. Optional seal configuration 350 is located outside edges 242, 244, 262, 264 and 266 with respect to center of the container 210. In other words, the optional seal configuration 350 is located farther from the center of the container 210 than from the edges. The optional seal configuration 350 in conjunction with a corresponding seal shape or configuration in another container (e.g., the optional seal configuration 450 shown in Figure 15), together with the closing edges of the container assembly, help to prevent or prevent the material from escaping or entering the container assembly. The optional seal configuration is especially useful to prevent or prevent product leakage, which could happen due to tolerances within the manufacturing process. In order to provide an efficient seal, the height of the optional seal configuration must be at least half the height of the edge. This is shown in Figure 15 where the optional seal configurations 350 and 450 make contact with each other. As discussed above with respect to Figures 16a, b the optional seal configuration could be located within the edges, so that the seal is formed closer to the center of the container assembly compared to the edges that can be closed in a releasable manner. A container assembly 400 according to one embodiment of the present invention is shown in Figures 14a, 14b. The container 400 comprises a first container 210 and a second container 410. In one embodiment, the second container 410 is substantially formed in the same manner as the first container 210. Alternatively, the second container 410 could be identical to the container 210. first container 210. As discussed above, the container assembly could be formed with a first and second different containers than the dishes. For example, the container assembly could be formed using a bowl and a plate. The container assembly 400 of Figures 14a, 14b could be formed in accordance with a method by providing the first container 210 and the second container 410. The second container 410 includes a continuous body portion. 412 and a flange 414 continued to surround and protrude laterally outward from the body portion 412. Similarly, the first container 210, as discussed above, includes the continuous body portion 212 and the flange continued 214 that surrounds and protrudes laterally outwardly from body portion 212. Both of flanges 214, 414 include a respective plurality of edges with spaces therebetween (not shown in Figures 14a, 14b). Each of the plurality of edges could be configured and sized in a manner similar to the edges 220 shown above in Figures 10-13. Each of the plurality of edges generally protrudes upward therefrom (i.e., in a direction away from the continuous body portion). As discussed previously with the container assembly 100, the second container 410 is turned 180 degrees relative to the first container 210, so that the containers 210, 410 are generally aligned and the edges 214, 414 are adjacent to each other. This tumbled position of the container 410 relative to the container 210 is shown in Figure 14a. With reference to Figure 15, the adjacent edges 262, 264, 266 of a container assembly 210 are placed within the respective second spaces 422, 424 and 426 of the container 410 and the edges 418, 420 of the container 410 they are placed within the respective spaces 268, 270, so that the container assembly 400 can be releasably closed. With reference to Figures 17-21, a container (e.g., plate 610) that will be used in a further embodiment of the present invention is shown. The plate 610 is used with a second plate 710 (see Figures 22 and 23) which could be substantially the same or, alternatively, identical to the plate 610 to form a container assembly that can be releasably closed. With reference to Figures 17-18, the container 610 includes a continuous body portion 612 and a continuous flange 614 that surrounds and protrudes laterally outwardly from the body portion 612. The body portion 612 includes a lower portion 616 and a continuous side wall 618 that surrounds and protrudes upwards and outwards from the lower part 616. It is contemplated that the side wall could protrude only upwards from the lower part 616 or could even project upwards and inwards from the lower part. 616. It is also contemplated that the flange could not be continuous, although it is preferred that it be continuous. The optional handle portions 652 are included in the container 610 to assist the user's ability to use the container 610. Referring specifically to Figure 18, the continuous flange 614 includes a plurality of edges 620 projecting generally upward therefrom. The plurality of edges 620 is spaced around the general periphery of the container 610 and helps form a container assembly that can be releasably closed. The orientation of the plurality of edges 620 creates a pattern that is generally perpendicular to the direction of the flange 614. More specifically, the orientation of the plurality of edges 620 could create a pattern that is perpendicular to the direction of the flange 614. In a radial configuration with a pattern that is perpendicular to the direction of the flange, each of the plurality of edges 620, if extended inward, would pass through the general center of the plate. However, the plurality of edges 620 could be formed in different patterns from those shown in Figure 18 with respect to the flange 614 (for example, in the diagonal direction). The container 610 of Figure 18 has exactly 44 edges formed in the continuous flange 614. It is contemplated that the number of edges could vary from what is shown in Figure 18. For example, a container could have from 3 to 10 edges. A container generally has 20 to 60 edges. Typically, the containers have approximately 30 to 50 edges. The desired number of edges formed in the container will often vary in function of factors such as the size or shape of the container assembly, the type and thicknesses of the material (s) of the container assembly, and the desired retention strength of the container assembly. The desired strength of retention or clamping is a function of factors such as the weight of the product placed in the container assembly and its known use. With reference to Figures 19-21, the plurality of edges 620 is shown in greater detail. Specifically, a cross-sectional view of Figure 19 shows two adjacent edges projecting upward from the continuous flange 614. Figure 19 depicts a first edge 620a and a second edge 620b with a space 622 that is formed therebetween. The first edge 620a of Figure 19 comprises a generally flat surface 624 joining two side walls 626, 628. The first edge 620a is shown to be generally perpendicular to the plane of the rest of the continuous flange. Specifically, the first edge 620a is shown to be generally perpendicular to the plane EE formed along the remainder of the rim 614 in Figure 19. More specifically, the edge could be perpendicular to the plane of the remainder of the rim. The side walls 626, 628 are spaced from each other and shown to be generally perpendicular to the EE plane of the remainder of the flange 14. However, the side walls 626, 628 are not they necessarily have to be generally perpendicular or perpendicular to the remainder of the flange 14. Similarly, the second edge 620 of Figure 19 comprises a generally planar surface 630 joining two side walls 632, 634. The second edge 620b is shown to be generally perpendicular to the EE plane of the remainder of the flange 614. The side walls 632, 634 are spaced from each other and shown to be generally perpendicular to the EE plane of the remainder of the flange 614. In order to provide an improved closure container assembly, the minus one of the edge side walls could have a slanted cut. This optional undercut that is formed in the side edge wall engages with a similar slant cut in a corresponding space formed between the adjacent edges of the second container when the container assembly is formed. This is discussed below in further detail with respect to Figures 22-24. For example, in Figure 19, the optional biased cuts 626a, 628a are formed in the respective side walls 626, 628. The shape and size of the biased cut will vary depending on factors such as the size or shape of the mounting container, the type and thicknesses of the container assembly material (s), and the desired retention resistance of the container assembly. The The desired strength of retention or clamping is a function of factors such as the weight of the product placed in the container assembly and its known use. The number of skewed cuts formed in the sidewalls of the edge, if any, is a function of factors such as the desired strength of retention, the desired resistance against leakage or leakage, the type of the closing mechanism, the degree of manufacture of the container assemblies and the type and thicknesses of the material (s) used to form the container assemblies. For example, if the container assemblies were made from a first material having a coefficient of friction higher than a second material, then the processed container of the first material will probably need less biased cuts in its side walls than the same container made with the second material so that it has the same holding strength. The number of slanted cuts used is also a function of the use position for a particular application of the container assembly, which includes the retention resistance thereof. It is contemplated that the edges could have side walls without biased cuts or at least one biased cut (e.g., the first edge 620a with the optional biased cuts 626a, 628a in Figure 19). It is also contemplated that some edges within the same container could not have skewed cuts, while other edges could have one or more skewed cuts. With reference to Figure 20 the adjacent edges 642, 644 of a portion of the rim 614 are shown in greater detail. Figure 20 shows the adjacent edges 642, 644 with the respective generally planar areas 642a, 644a. The edges 642, 644 are separated with a generally flat area 646 that is formed between the generally planar areas 642a, 644a. In Figure 21, the top view of the edges 636, 638 shows that the edges 636, 638 become generally tapered inward toward the center of the container. Figure 21 also shows a generally flat area 636a of the edge 636 and a generally flat area 638a of the edge 638. In order to improve the seal of the container assembly, the generally flat areas 636a, 638a could make contact with flat areas of similar size formed in the respective spaces between the adjacent edges of a second container forming the container assembly. An example of a flat area of similar size formed in the space between the adjacent edges is shown in Figure 21 with the generally flat area 640. A rounded portion 654 transits the generally planar areas 636a, 638a of the edges 636, 638 toward the portion of body 612 of container 610. Rounded portion 654 assists in the operation of the container assembly so that it can be releasably closed. The rounded portion 654 facilitates alignment of the edges with their respective spaces as shown in Figure 24, allowing the edges to slide into their respective spaces when a container assembly is formed. It is contemplated that the shape and size of the plurality of edges 620 could vary from those shown in Figures 18-21. It is preferred that the plurality of edges be configured and dimensioned to minimize the stacking height of the containers used to form the container assemblies. It is desirable to minimize the stacking height of the containers to (a) decrease transportation and packaging costs, and (b) provide space efficiency in the retail and consumer facilities. It is also desirable to maximize the holding strength of the container assembly. The desired retention resistance is often a balance between making the container assembly for the consumer to open and close it easily, while still preventing or preventing inadvertent opening of the container assembly. Referring once more to Figure 20, an optional shape or configuration of seal 650 formed on the flange 614 is depicted. In Figure 20, the shape or Optional seal configuration 650 is located outwardly from edges 642, 644 relative to the center of vessel 610. In other words, optional seal configuration 650 is located farther from the center of vessel 610 than from edges 642, 644. The optional seal configuration 650 in conjunction with the corresponding optional seal configuration in another container (not shown), together with the closing edges of the container assembly, help prevent or prevent the material from escaping or entering the container. container assembly. The optional seal configuration is especially useful to prevent or prevent product leakage that could happen due to tolerances within the manufacturing process. In order to provide an efficient seal, the height of the optional seal configuration 650 must be at least half the height of the edge. However, the optional seal configuration could be located within the edges, so that the seal is formed closer to the center of the container assembly compared to the edges that can be releasably closed. The optional seal configuration could be formed in a variety of configurations, including a conical general shape. The container assembly 700 according to one embodiment of the present invention is shown in Figures 22, 23. The container assembly 700 comprises a first container 610 and second container 710. In one embodiment, second container 710 is substantially configured in the same manner as first container 610. Alternatively, second container 710 could be identical to first container 610. It is also desirable to have containers configured identically to reduce waste by the consumer when the upper container or lid is not used. As discussed above, the container assembly could be formed with a first and second container different than the plates. The container assembly 700 of Figures 22, 23 could be formed in accordance with a method by providing the first container 610 and the second container 710. The second container 710 includes a continuous body portion 712 and a continuous flange 714 surrounding and It protrudes laterally outward from the body portion 712. Similarly, the first container 610 as discussed above, includes the continuous body portion 612 and the continuous flange 614 that surrounds and protrudes laterally outwardly of the body. body portion 612. Both of the shoulders 614, 714 include a respective plurality of respective edges with spaces therebetween (not shown in Figures 22, 23). Each of the plurality of edges could be configured and sized similarly to the edges shown in Figures 18-21. Each one of the plurality of edges generally protrudes upward therefrom (i.e., in a direction away from the continuous body portion). The second container 710 is turned 180 degrees relative to the first container 610, so that the containers 610, 710 are generally aligned and the flanges 614, 714 are adjacent to each other. This inverted position of the container 710 relative to the container 610 is shown in Figure 22. To place the edges within the respective spaces, the container 710 may have to be rotated in a light manner, so that the edges are displaced (i.e. , that the edges and spaces are aligned). It is desirable that the consumer be able to assemble the containers to form a container assembly of the present invention. With reference to Figure 24, the adjacent edges 720a, 720b of the container 710 are placed within the respective second spaces 622a, 622b of the container 610 and the edges 620a, 620b of the container 610 are placed within the respective spaces 722a, 722b, so that the container assembly 700 can be releasably closed. To place the edges within the respective spaces, the container 710 may have to be rotated in a light manner, so that the edges are displaced (ie, the edges and spaces are aligned). The Figure 24 also represents the interference zones 724a, 724b formed between the first edge 620a and the space 722a created between the edges 720a, 720b of the container 710. The resistance of this lock that can be immobilized is a function of many variables such as the number of protruding edges, the height of these edges, if skewed cuts are included, the size of the contact areas, the necessary clearance between the spaces and edges, and the type and thickness of the material (s) that are used to form the container assemblies. To improve the degree of closure of the container assembly, as discussed above, an optional sealing feature or configuration could be added. The container assemblies of the present invention are normally formed from polymeric materials although they could be formed from materials such as paper or metal. The polymeric containers could be formed from polyolefins. Normally, polymeric food containers are formed from oriented polystyrene (OPS), polyethylene terephthalate (PET), high impact polystyrenes (HIPS), polyvinyl chloride (PVC), polypropylene and combinations thereof. The container assemblies could be made from a polymeric material filled with mineral, such as, for example, talc or polyolefin filled with carbonate of calcium. An example of the paper that could be used to form container assemblies is cardboard or molded fiber. Commonly, the paperboard and the molded fiber have a sufficient coefficient of friction to hold the first and second containers in a position that can be closed. As discussed, the materials used for shaping the container assembly could help to releasably close the container assembly. For example, the material (s) forming the container assembly could have an almost adherent laminate on one side corresponding to an almost adherent laminate on the opposite side, resulting in a desirable container assembly that can be releasably closed. It is contemplated that the containers used for shaping the container assemblies could be made of different materials. It is contemplated that a person of ordinary skill in the art will recognize that other polymers or combinations of polymers could be used to form the containers. Typically, the container assemblies of the present invention are disposable, although it is contemplated that they could be reused at a future time. The containers used to form the container assemblies (e.g., the container 10) are shown to include a compartment. It is contemplated that the containers could be formed of multiple compartments. It is desirable that these containers be used for placing products (eg, food products) in different compartments to avoid or prevent mixing of the products. For example, undesirable mixing of food products could contaminate the taste and consistency of food products. As discussed above, container assemblies could be used with food products. One method of using these container assemblies includes placing the food and closing the containers to form a container assembly with food therein. Next, the container assembly is placed in a hot apparatus and then heated. Common heating appliances include conventional microwave ovens and ovens. The container assemblies could contain solid food products. The container assemblies could be used for storage in the refrigerator and / or freezer. The containers that will be used to form the container assemblies of the present invention, could be formed using conventional thermoforming processes (eg, by pressure, vacuum or combination thereof), injection molding, or molding rotation. According to a thermoforming method, The granules of a polymer resin and additives, if any, are added in an extruder. The granules of the polymeric resin and additives, if any, are combined to form a mixture. The mixture is extruded through a matrix to form an extruded sheet. The extruded sheet is thermoformed into a desired configuration of the container that will be used to form the container assembly. The thickness of the container that will be used to form the container assemblies fluctuates, generally, from 0.01 centimeters (0.002 inches) to 0.38 centimeters (0.15 inches), although it is usually approximately 0.01 centimeters (0.005 inches) to 0.10 centimeters (0.04 inches). inches). The container assemblies could be opaque or a variety of colors or color combinations. The container assemblies would normally have at least one transparent container if it is desired that the customer evaluate the nature of the accommodated product and the condition thereof without having to open the container assembly. While the particular embodiments and applications of the present invention have been illustrated and described, it will be understood that the invention is not limited to the precise construction and compositions described herein and that various modifications, changes and variations could be apparent from the previous descriptions without departing from the spirit and scope of the invention as defined in the appended claims.
