Definitions
- the following invention relates to dishes upon which food can be placed for presentation and also eating directly therefrom. More particularly, this invention relates to dishes which include a removable lid placeable thereon and which dishes are formed of organic material, such as pressed palm leaves.
- Culinary dishes can be formed from a variety of different materials and have a variety of different shapes.
- the shapes can vary from a plate-like dish which is almost entirely flat, but typically has a rim which extends slightly higher than a floor, to a dish that is more in the form of a bowl, with a rim significantly higher than a floor of the dish.
- Dishes can be round, square, rectangular, or other shapes.
- Dishes can be formed of durable materials which can be readily sanitized so that the dishes are generally reusable, or can be formed to be disposable. Disposable dishes are convenient, especially when provided with food thereon for sale. A purchaser can potentially eat the food off of the disposable dish and then dispose of the dish without having the burden of washing and storing the dish until ready to be used again. However, disposable dishes increase the waste which ends up either requiring recycling or dumping into a landfill.
- Some materials are known which are compostable and/or biodegradable.
- some wood pulp or wood fiber pressed materials such as in the form of fiberboard or thick craft paper or cardboard materials
- Such paper based materials are not entirely satisfactory for display and sale of food items thereon because the material, being somewhat water soluble, will to some degree absorb moisture in the food item being presented, and cause discoloration and/or sogginess of the dish.
- the leaf pressed into a dish form maintains a desirable organic appearance, with lines apparent therein and a color thereof, as well as a texture which readily conveys to the user that the dish is formed of a natural organic material.
- variable nature of the input stock placed into the press leaves the dish with some degree of variableness in thickness, perimeter contour, and a degree to which an upper edge of the side walls terminates within a single common plane. While such variability adds uniqueness and interest to such dishes, this variability and the upwardly extending upper edges of the sides of such prior art dishes have made it impractical to form a lid which can effectively attach to such dishes, especially with a reliability that a lid will attach to all or substantially all dishes, rather than having a high failure rate due to the variability in the final shape of such prior art dishes.
- Lids are important for many situations. For instance, when food items are presented for sale in a store or restaurant it is often desirable for the food items to have a cover.
- This cover is often in the form of a clear plastic lid which is removable from the dish.
- a clear plastic cover allows a purchaser to see the food item through the lid, and yet have confidence that other shoppers have not handled the food item directly because the lid has protected the food item, and also that flies or other flying insects have been kept from contact with the food items.
- a dish is provided and also a cover which can attach to the dish and be secured thereto in a removable fashion, even when the dish has some degree of variability in thickness thereof and flatness of perimeter portions thereof.
- the dish utilizes areca palm leaves which are pressed between platens to form the dish of the final desired shape. While examples shown herein are rectangular or square, other shapes could be provided by merely modifying the shape of platens used to form the dish. Various sizes can also be accommodated by changing sizes of the platens.
- a perimeter of the dish is not left as an upwardly extending upper edge of sides which extend up from a floor. Instead, a rim is provided which extends substantially laterally from upper edges of the sides to a lateral side defining a tip of the rim. The rim, so located and configured, provides a structure to which a perimeter latch on a lid can effectively attach.
- the dish is formed by having appropriately shaped top and bottom platens pressed together upon an areca palm leaf (or potentially leaves or other organic leaf-like structures, preferably also along with the addition of heat and steam) to produce the final dish with the desired shape.
- the original shape and thickness of the leaf will cause variability of the dish at the rim in at least two ways. First, a thickness of the rim between a top side and an underside will vary somewhat based on a thickness of the original leaf material placed into the press. Second, based on the original geometry of the leaf, and other factors, such as variability in moisture content of the leaf, after the leaf material comes out of the press it may warp to some extent so that the rim is not entirely planar.
- first and third corners diagonally opposite each other might be higher than second and fourth corners diagonally opposite each other and in-between the first and third corners.
- Such a warping shape will cause the rim to be slightly non-planar.
- Standard prior art lids with perimeter latches thereon cannot accommodate such rim thickness variability and rim warpage. Rather, this thickness variability and warpage will cause prior art lids to have a high failure rate where the lid might initially be placed onto the dish, but then have at least one corner thereof pop off of the rim of the dish. If such failure occurs when the lid is first put on, a user has the undesirable but possible option of discarding the dish and selecting a second dish which has a more uniform shape.
- the lid can often pop off after the passage of some time, especially when food items stored therein are placed within a refrigerated location, where the temperature change will over time apply forces associated with thermal contraction of the lid and dish at different rates, which along with the shape of the lid and warpage and thickness variation of the dish will cause connection failure.
- a lid which accommodates the thickness variation and warpage within the dish so that all or substantially all dishes can have the lid securely held thereto.
- a perimeter latch of the lid extends downwardly from side walls which extend down from a top surface of the lid.
- This perimeter latch has at least one indentation which extends laterally inwardly from a primary downwardly extending perimeter latch structure.
- An upper recess is provided above this at least one indentation.
- the upper recess is carefully sized to have a height dimension between the indentation and upper portions of the perimeter latch which extend inwardly before connecting to the side walls which extend down from the top surface. This height of the upper recess is sized to be greater than a thickness of the rim of the dish at the tip thereof.
- This oversizing of the upper recess is preferably about fifty percent greater than a thickest anticipated rim for the dish.
- this upper recess accommodates warpage in the rim without requiring the perimeter latch of the lid to itself warp along with the dish to remain attached thereto.
- a lid of a single highly uniform size can fit dishes which have a close to uniform size but exhibit some variability due to the natural character thereof.

- the rectangular dish 10 and square dish 20 are identical in form except that a top plan shape thereof is either rectangular (for the rectangular dish 10 ) or square (for the square dish 20 ).
- Common reference numerals are utilized for details of the rectangular dish 10 and square dish 20 , where the only difference therebetween is the shape thereof being rectangular or square.

- This rim 50 is formed as a unitary mass along with the sides 40 and floor 30 .
- this forming occurs by pressing an areca palm leaf between upper and lower platens having a gap therebetween similar in shape to a desired contour for the dish 10 .
- Platens of different shapes can be provided, such as to provide the square dish 20 , or to provide different sizes. While generally square and rectangular dishes are shown herein, the platens could be shaped to produce generally round dishes as an alternative, or other shapes.
- the rim 50 extends substantially horizontally away from the upper edge 44 of the sides 40 . In a preferred embodiment, this rim 50 completely circumscribes the dish 10 . Particular details of the rim 50 are described in detail below.
- Lids such as the rectangular lid 60 are provided having a standardized form.
- the lid 60 is formed of at least partially transparent material, such as plastic.
- the plastic is vacuum formed plastic.
- the plastic material can be biodegradable, such as by being formed at least partly of corn starch based polylactic acid (PLA). Such biodegradable and compostable plastic can still be at least partially transparent.
- the lid 60 generally has a top surface 80 which is substantially planar and with side walls 90 extending down from the top surface 80 .
- a perimeter latch 100 also called a perimeter skirt 100 ) is located at a lower end of the side walls 90 . This perimeter latch 100 is shaped to removably attach to the rim 50 of the dish 10 .
- Side walls 90 of the lid 60 can have a variety of different shapes.
- the side walls 90 have a curving transition 92 adjacent the top surface 80 which transitions into a vertical surface. This vertical surface then transitions to a horizontal surface which forms a step 94 extending laterally somewhat further than other portions of the side walls 90 . Lower portions of the step 94 transition into the perimeter latch 100 which defines a greatest diameter perimeter of the rectangular lid 60 .
- Other geometries for the side walls 90 could also be provided.
- a height of the side walls 90 can be increased. While the top surface 80 is shown generally flat, it could be domed or have other shapes. While the side walls 90 are shown vertical over large portions thereof, the side walls 90 could maintain a lateral taper between the top surface 80 and the perimeter latch 100 , rather than having vertical portions thereon. While the step 94 can add some rigidity to the lid 60 , the step 94 could be avoided or multiple steps 94 could be provided or other undulating or other structures provided within the side walls 90 , either for structural strength or to add a desirable and interesting appearance to the lid 60 . Details of the perimeter latch 100 for coupling to the rim 50 are described in detail below.
- the rim 50 has an inner edge 52 adjacent the upper edge 44 of the sides 40 .
- An outer edge 54 is provided opposite the inner edge 52 .
- the rim 50 has a top side 56 extending between the inner edge 52 and the outer edge 54 .
- An underside 58 is provided opposite the top side 56 and also extending from the inner edge 52 to the outer edge 54 .
- a lateral side 55 preferably is oriented vertically and extends between the top side 56 and underside 58 at the outer edge 54 . This lateral side 55 defines a tip of the rim 50 defining a greatest diameter of the rim 50 and a greatest diameter of the dish 10 .
- the lateral side 55 is formed typically by some form of cutting procedure.
- the platens which form the dish 10 can have cutters at edges thereof, such as with a top platen having a sharp cutting edge and the bottom platen having a reference surface against which the cutting edge can abut, so that the lateral side 55 of the rim 50 is formed at the same time that other portions of the dish 10 are formed.
- the lateral side 55 of the rim 50 can be formed in a separate secondary procedure to trim the rim 50 and provide the lateral side 55 .
- a final thickness of the rim 50 at the lateral side 55 can vary to some degree. For instance, if the lateral side 55 is designed to be two millimeters thick, it might actually vary between 1.5 millimeters and 2.5 millimeters in thickness.
- some degree of “memory” in the areca palm leaf or other material, or potentially structural characteristics of the leaf material itself can cause the dish to warp somewhat after removal from the press.
- Such warpage is typically hardly noticeable, but causes the top side 56 of the rim 50 to be less than entirely planar. Because this warpage is quite small, it is not visible in the drawings shown herein. While the warpage can involve only a single corner or side being higher or lower than other portions thereof, in other situations, two opposite corners might be elevated and two other opposite corners might be lowered with such a warped rim 50 . Such a warped rim 50 might have a height differential between lower corners or sides and higher corners and sides which might vary one to two millimeters from each other.
- Lid 60 materials such as vacuum moldable plastic materials, have a small amount of flexibility which can accommodate some degree of warpage or variability in rim 50 thickness. However, there are limits to the degree to which such lids can accommodate such warpage. Thus, to provide a lid 60 which can attach to dishes 10 which may have an unacceptably wide range of warpage or rim 50 thicknesses, the perimeter latch 100 of the lid 60 is configured to accommodate this variability.
- the perimeter latch 100 extends downwardly from lowermost portions of the side walls 90 to define both a lowermost and outermost portion of the lid 60 .
- This perimeter latch 100 is generally vertical except where at least one indentation 104 extends inwardly thereon and at a lowermost edge where a horizontal tab 108 optionally but preferably extends outwardly therefrom.
- an upper recess 102 is provided between the indentation 104 and upper portions of the perimeter latch 100 .
- a lower recess 106 is provided below the indentation 104 which ends at the horizontal tab 108 and the lower edge of the perimeter latch 100 .
- the upper recess 102 has a particular height and depth. The height is measured between upper portions of the at least one indentation 104 and upper portions of the perimeter latch 100 . A depth of the upper recess 102 is generally similar to a depth of the indentation 104 extending laterally in from other substantially vertical portions of the perimeter latch 100 .
- the at least one indentation 104 is shown as a plurality of elongate discrete indentations 104 with gaps therebetween in the rectangular dish 10 of FIGS. 1 and 5-7 .
- the square dish 20 shows a more continuous single indentation within the perimeter latch 100 thereof.
- the depth of the upper recess 102 formed by the depth of the indentations 104 is carefully selected so that the perimeter size of the rim 50 at the lateral side 55 thereof can snap past the indentations 104 and into the upper recess 102 , and the process can be reversed by snapping the lateral side 55 of the rim 50 out of the upper recess 102 for removal of the lid 60 .
- this depth of the upper recess 102 is provided at four millimeters by having indentations 104 extend four millimeters inward from vertical portions of the perimeter latch 100 .
- the perimeter latch 100 can be positioned at a location which is two millimeters greater than a diameter of the rim 50 at the lateral side 55 .
- the height of the upper recess 102 is preferably sized to be greater than a typical maximum thickness of the rim 50 at the lateral side 55 .
- the upper recess 102 would have a height which is greater than 2.5 millimeters.
- the upper recess 102 has a height which is fifty percent greater than a maximum typical thickness of the rim 50 at the lateral side 55 .
- the upper recess 102 would have a height of 3.75 millimeters. In this way, the upper recess 102 both accommodates variability in thickness of the rim 50 and also warpage of the rim 50 to some extent.
- the lid 60 can to at least a small degree warp along with the dish 10 so that the perimeter latch 100 can remain attached to the dish 10 at the rim 50 . Furthermore, the lid 60 can be sufficiently strong so that to some extent it can “de-warp” the dish 10 somewhat and still have the perimeter latch 100 of the lid 60 remain securely attached to the rectangular dish 10 , and also be readily removable and re-attachable to the dish 10 by a user.
- a dish 10 will have a rim 50 which is not warped and will have a thickness at the lateral side 55 of the rim 50 which is not oversized.
- the lid 60 may exhibit a small amount of looseness, but the depth of the upper recess 102 is sufficiently great that such looseness is not sufficient for the lid 60 to come off of the rim 50 of the dish 10 , so that substantially all extremes of variability in the geometry of the dish 10 are accommodated by the configuration of the perimeter latch 100 of the lid 60 .
- the perimeter latch 100 preferably has a substantially uniform configuration around an entire perimeter of the lid 60 .
- a corner grip 110 is provided where a horizontal tab 108 at a lowermost edge of the perimeter latch 100 extends further laterally than other portions of the perimeter latch 100 , and is preferably located at a corner of the lid 60 .
- a rib 112 is inboard and on top of this corner grip 110 which can add some rigidity to the corner grip 110 .
- the corner grip 110 provides a location where a user can grip the lid 60 and apply an upward force focused at this corner to separate the perimeter latch 100 from the rim 50 , so that the lid 60 can be removed from the dish 10 .
- the square dish 20 and square lid 70 accommodate removal of the square lid 70 by providing a corner relief 120 at a corner of the square lid 70 .
- This corner relief 120 is somewhat less rounded than other corners so that a user can insert a finger under the corner relief 120 and grab the rim 50 and then use the finger (or some tool such as a handle of a spoon, fork or knife) to pivot upwards and separate the square lid 70 from the square dish 20 .
- the corner relief 120 and corner grip 110 could be swapped for each other on the dishes 10 , 20 or different corners of a common dish 10 , 20 could be provided with either the corner grip 110 or the corner relief 120 .
- the corner relief 120 can also provide a small amount of ventilation if desired for an interior of the dish 10 , 20 beneath the lid 60 , 70 , such as to reduce condensation therein, but preferably sufficiently small to prevent flies or other flying insects from passing into this enclosure.

Abstract
The dish is formed by pressing a palm leaf to form a generally concave dish with a floor surrounded by sides extending to an upper edge. A rim extends laterally from this upper edge, formed as a unit with the floor and sides of the dish. A lid is provided which has a top surface with side walls extending down to a perimeter latch. This perimeter latch engages the dish, such as by snapping onto the rim. In one embodiment the perimeter latch extends downwardly from other portions of the lid and has at least one indentation which extends inwardly thereon to provide an upper recess above the indentation which is sized to receive a tip of the rim. A height of the upper recess is oversized relative to a thickness of the tip of the rim to accommodate some variation in dish thickness and some degree of dish warping.
Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 14/706,525, filed on May 7, 2015 and issued as U.S. Pat. No. 10,004,345 on Jun. 26, 2018.
- The following invention relates to dishes upon which food can be placed for presentation and also eating directly therefrom. More particularly, this invention relates to dishes which include a removable lid placeable thereon and which dishes are formed of organic material, such as pressed palm leaves.
- Culinary dishes can be formed from a variety of different materials and have a variety of different shapes. The shapes can vary from a plate-like dish which is almost entirely flat, but typically has a rim which extends slightly higher than a floor, to a dish that is more in the form of a bowl, with a rim significantly higher than a floor of the dish. Dishes can be round, square, rectangular, or other shapes.
- Dishes can be formed of durable materials which can be readily sanitized so that the dishes are generally reusable, or can be formed to be disposable. Disposable dishes are convenient, especially when provided with food thereon for sale. A purchaser can potentially eat the food off of the disposable dish and then dispose of the dish without having the burden of washing and storing the dish until ready to be used again. However, disposable dishes increase the waste which ends up either requiring recycling or dumping into a landfill.
- Some materials are known which are compostable and/or biodegradable. For instance, some wood pulp or wood fiber pressed materials (such as in the form of fiberboard or thick craft paper or cardboard materials) are known which can meet various different criteria for at least some degree of biodegradability or compostability. Such paper based materials are not entirely satisfactory for display and sale of food items thereon because the material, being somewhat water soluble, will to some degree absorb moisture in the food item being presented, and cause discoloration and/or sogginess of the dish.
- One highly effective and fully compostable and biodegradable material has more recently been known to be formed into a dish which is formed of palm leaves of the areca palm. When leaves of the areca palm are pressed under high pressure between plates having a shape with a gap between the plates similar to a desired shape for a plate, and with such pressing also occurring with the application of heat and/or moisture, the leaf is pressed into a dish shape. The areca leaf has some degree of waxiness naturally present therein which leaves the pressed leaf dish with a natural coating which resists absorption of moisture sufficient to avoid “sogginess” even when wet food items are placed thereon. As a further benefit, such dishes formed of palm leaves only require the application of pressure, heat and/or steam to be formed into a dish. No chemicals or other additives are required, so that full compostability and full biodegradability and food grade usability is obtained. Furthermore, the leaf pressed into a dish form maintains a desirable organic appearance, with lines apparent therein and a color thereof, as well as a texture which readily conveys to the user that the dish is formed of a natural organic material.
- One problem which has been encountered with the manufacture of dishes from pressed palm leaves is that the variable nature of the input stock placed into the press leaves the dish with some degree of variableness in thickness, perimeter contour, and a degree to which an upper edge of the side walls terminates within a single common plane. While such variability adds uniqueness and interest to such dishes, this variability and the upwardly extending upper edges of the sides of such prior art dishes have made it impractical to form a lid which can effectively attach to such dishes, especially with a reliability that a lid will attach to all or substantially all dishes, rather than having a high failure rate due to the variability in the final shape of such prior art dishes.
- Lids are important for many situations. For instance, when food items are presented for sale in a store or restaurant it is often desirable for the food items to have a cover. This cover is often in the form of a clear plastic lid which is removable from the dish. A clear plastic cover allows a purchaser to see the food item through the lid, and yet have confidence that other shoppers have not handled the food item directly because the lid has protected the food item, and also that flies or other flying insects have been kept from contact with the food items. Accordingly, a need exists for a pressed leaf dish which can have a sufficiently uniform contour at a perimeter thereof that a lid can attach effectively thereto, and a need also exists for a lid appropriately modified to accommodate some degree of variability in the thickness and flatness of perimeter portions of the dish, so that a lid can be provided which can effectively attach to a pressed leaf dish.
- With this invention a dish is provided and also a cover which can attach to the dish and be secured thereto in a removable fashion, even when the dish has some degree of variability in thickness thereof and flatness of perimeter portions thereof. The dish utilizes areca palm leaves which are pressed between platens to form the dish of the final desired shape. While examples shown herein are rectangular or square, other shapes could be provided by merely modifying the shape of platens used to form the dish. Various sizes can also be accommodated by changing sizes of the platens.
- Uniquely with this invention, a perimeter of the dish is not left as an upwardly extending upper edge of sides which extend up from a floor. Instead, a rim is provided which extends substantially laterally from upper edges of the sides to a lateral side defining a tip of the rim. The rim, so located and configured, provides a structure to which a perimeter latch on a lid can effectively attach.
- The dish is formed by having appropriately shaped top and bottom platens pressed together upon an areca palm leaf (or potentially leaves or other organic leaf-like structures, preferably also along with the addition of heat and steam) to produce the final dish with the desired shape. The original shape and thickness of the leaf will cause variability of the dish at the rim in at least two ways. First, a thickness of the rim between a top side and an underside will vary somewhat based on a thickness of the original leaf material placed into the press. Second, based on the original geometry of the leaf, and other factors, such as variability in moisture content of the leaf, after the leaf material comes out of the press it may warp to some extent so that the rim is not entirely planar.
- For instance, if the dish is square, first and third corners diagonally opposite each other might be higher than second and fourth corners diagonally opposite each other and in-between the first and third corners. Such a warping shape will cause the rim to be slightly non-planar. Standard prior art lids with perimeter latches thereon cannot accommodate such rim thickness variability and rim warpage. Rather, this thickness variability and warpage will cause prior art lids to have a high failure rate where the lid might initially be placed onto the dish, but then have at least one corner thereof pop off of the rim of the dish. If such failure occurs when the lid is first put on, a user has the undesirable but possible option of discarding the dish and selecting a second dish which has a more uniform shape. However, the lid can often pop off after the passage of some time, especially when food items stored therein are placed within a refrigerated location, where the temperature change will over time apply forces associated with thermal contraction of the lid and dish at different rates, which along with the shape of the lid and warpage and thickness variation of the dish will cause connection failure.
- With this invention, a lid is provided which accommodates the thickness variation and warpage within the dish so that all or substantially all dishes can have the lid securely held thereto. In particular, a perimeter latch of the lid extends downwardly from side walls which extend down from a top surface of the lid. This perimeter latch has at least one indentation which extends laterally inwardly from a primary downwardly extending perimeter latch structure. An upper recess is provided above this at least one indentation. The upper recess is carefully sized to have a height dimension between the indentation and upper portions of the perimeter latch which extend inwardly before connecting to the side walls which extend down from the top surface. This height of the upper recess is sized to be greater than a thickness of the rim of the dish at the tip thereof. This oversizing of the upper recess is preferably about fifty percent greater than a thickest anticipated rim for the dish. Thus, this upper recess accommodates warpage in the rim without requiring the perimeter latch of the lid to itself warp along with the dish to remain attached thereto. In this way, a lid of a single highly uniform size can fit dishes which have a close to uniform size but exhibit some variability due to the natural character thereof.
- Accordingly, a primary object of the present invention is to provide a dish which is formed of a natural material, such as a palm leaf material, and which can function effectively as a dish, even accommodating a cover, such as a lid thereon.
- Another object of the present invention is to provide a lid for a dish having some variability in perimeter shape, which lid can attach securely to dishes of this somewhat variable geometry.
- Another object of the present invention is to provide an assembly for display of food which is attractive to purchasers.
- Another object of the present invention is to provide a food display dish and lid combination which includes a fully biodegradable and compostable dish portion.
- Another object of the present invention is to provide a food display dish and lid which includes both a lid and a dish which are fully biodegradable and compostable.
- Another object of the present invention is to provide a dish and lid combination which has a clear lid through which a food item and the dish can be clearly seen.
- Another object of the present invention is to provide a lid for a dish which lid has a perimeter latch which can accommodate warped dishes and/or dishes having perimeter rims of variable thickness.
- Another object of the present invention is to provide a method for display of a food item upon a pressed palm leaf dish having a somewhat variable perimeter geometry under a lid of standardized shape.
- Other further objects of the present invention will become apparent from a careful reading of the included drawing figures, the claims and detailed description of the invention.

FIG. 8 is a detail of a portion of that which is shown inFIG. 6 , showing how the perimeter latch of the lid attaches to a rim of the dish. - Referring to the drawings, wherein like reference numerals represent like parts throughout the various drawing figures,
reference numeral 10 is directed to a rectangular dish (FIG. 3 ) which can have a rectangular lid 60 (FIG. 5 ) removable attached thereto to provide a rectangular assembly 1 (FIG. 1 ). An alternative embodiment square assembly 2 is also shown (FIG. 2 ) with a square dish 20 (FIG. 4 ) and asquare lid 70 removably attachable to thesquare dish 20. The dish is preferably formed by pressing of an areca palm leaf between platens to form the final dish shape. The lid is provided with aperimeter latch 100 which accommodates some variability in thickness and contour of therim 50 of the 10, 20 so that adish 60, 70 can attach to astandard size lid rim 50 of the 10, 20 when it has some variability in geometry.dish - In essence, and with particular reference to
FIGS. 1 and 6-8 , basic details of the invention are described, according to a preferred embodiment. To accommodate variability in perimeter structure of the dish, such as therectangular dish 10, both thedish 10 and thelid 60 are modified from prior art dishes and lids. Thedish 10 has afloor 30 which is generally planar and hassides 40 which extend up from thisfloor 30 toupper edges 44. Rather than having theupper edges 44 terminate in an upwardly extending direction, a laterally extendingrim 50 is provided at theupper edge 44 of thesides 40. Thisrim 50 extends to alateral side 55 which defines a tip of therim 50. - The
rectangular lid 60 has atop surface 80 withside walls 90 extending downward therefrom to aperimeter latch 100. Theperimeter latch 100 has a geometry including anupper recess 102, which is sized to accommodate arim 50 having variable thickness, and which can be warped out of a fully planar form by having theupper recess 102 oversized. Alid 60 of standard dimensions can thus attach todishes 10 which have some variability in thickness at therim 50 and some variability in the planar form of therim 50, while still allowing thelid 60 to remain securely attached to thedish 10 until removal is desired by a user. - More specifically, and with particular reference to
FIGS. 1-4 , basic details of the 10, 20 anddishes 60, 70 are described, according to various embodiments. Thelids rectangular dish 10 andsquare dish 20 are identical in form except that a top plan shape thereof is either rectangular (for the rectangular dish 10) or square (for the square dish 20). This illustrates how 10, 20 of different geometries can still feature the details of this invention for holding adishes 60, 70 to thelid 10, 20. Common reference numerals are utilized for details of thedish rectangular dish 10 andsquare dish 20, where the only difference therebetween is the shape thereof being rectangular or square. - The
dish 10 is shown herein having a plate-like form which is quite shallow between a substantiallyplanar floor 30 at a lower portion thereof and extending throughsides 40 which extend upwardly from thefloor 30. In this embodiment, thesides 40 curve upwardly from alower edge 42 adjacent thefloor 30 to anupper edge 44 opposite thelower edge 42. In other embodiments, thesides 40 could extend upwardly in a planar fashion. A height of thesides 40 could be greater or less than that depicted for thesides 40. For instance, if thedish 10 is to be configured more as a bowl, thesides 40 would be taller, and generally steeper. If thedish 10 is to be more in the form of a flatter plate, thesides 40 could extend upwardly at a more gradual angle and/or to a lesser extent up from thefloor 30. - Uniquely with this invention, the
sides 40 terminate at arim 50 adjacent theupper edge 44. Thisrim 50 is formed as a unitary mass along with thesides 40 andfloor 30. In a preferred embodiment, this forming occurs by pressing an areca palm leaf between upper and lower platens having a gap therebetween similar in shape to a desired contour for thedish 10. Platens of different shapes can be provided, such as to provide thesquare dish 20, or to provide different sizes. While generally square and rectangular dishes are shown herein, the platens could be shaped to produce generally round dishes as an alternative, or other shapes. - The
rim 50 extends substantially horizontally away from theupper edge 44 of thesides 40. In a preferred embodiment, thisrim 50 completely circumscribes thedish 10. Particular details of therim 50 are described in detail below. - Lids such as the
rectangular lid 60 are provided having a standardized form. Most preferably, thelid 60 is formed of at least partially transparent material, such as plastic. In one embodiment, the plastic is vacuum formed plastic. The plastic material can be biodegradable, such as by being formed at least partly of corn starch based polylactic acid (PLA). Such biodegradable and compostable plastic can still be at least partially transparent. Thelid 60 generally has atop surface 80 which is substantially planar and withside walls 90 extending down from thetop surface 80. A perimeter latch 100 (also called a perimeter skirt 100) is located at a lower end of theside walls 90. Thisperimeter latch 100 is shaped to removably attach to therim 50 of thedish 10. -
Side walls 90 of thelid 60 can have a variety of different shapes. In the embodiment shown, theside walls 90 have a curvingtransition 92 adjacent thetop surface 80 which transitions into a vertical surface. This vertical surface then transitions to a horizontal surface which forms astep 94 extending laterally somewhat further than other portions of theside walls 90. Lower portions of thestep 94 transition into theperimeter latch 100 which defines a greatest diameter perimeter of therectangular lid 60. Other geometries for theside walls 90 could also be provided. - If a larger or taller food item is to be placed upon the dish, a height of the
side walls 90 can be increased. While thetop surface 80 is shown generally flat, it could be domed or have other shapes. While theside walls 90 are shown vertical over large portions thereof, theside walls 90 could maintain a lateral taper between thetop surface 80 and theperimeter latch 100, rather than having vertical portions thereon. While thestep 94 can add some rigidity to thelid 60, thestep 94 could be avoided ormultiple steps 94 could be provided or other undulating or other structures provided within theside walls 90, either for structural strength or to add a desirable and interesting appearance to thelid 60. Details of theperimeter latch 100 for coupling to therim 50 are described in detail below. - With particular reference to
FIGS. 6-8 , details of therim 50 andperimeter latch 100 are described which cooperate together to allow thelid 60 to attach to thedish 10, even when thedish 10 has some variability in thickness and flatness according to a preferred embodiment. Therim 50 has aninner edge 52 adjacent theupper edge 44 of thesides 40. Anouter edge 54 is provided opposite theinner edge 52. Therim 50 has atop side 56 extending between theinner edge 52 and theouter edge 54. Anunderside 58 is provided opposite thetop side 56 and also extending from theinner edge 52 to theouter edge 54. Alateral side 55 preferably is oriented vertically and extends between thetop side 56 andunderside 58 at theouter edge 54. Thislateral side 55 defines a tip of therim 50 defining a greatest diameter of therim 50 and a greatest diameter of thedish 10. - The
lateral side 55 is formed typically by some form of cutting procedure. For instance, the platens which form thedish 10 can have cutters at edges thereof, such as with a top platen having a sharp cutting edge and the bottom platen having a reference surface against which the cutting edge can abut, so that thelateral side 55 of therim 50 is formed at the same time that other portions of thedish 10 are formed. Alternatively, thelateral side 55 of therim 50 can be formed in a separate secondary procedure to trim therim 50 and provide thelateral side 55. - Depending on the original thickness of the particular areca palm leaf or other organic matter placed within the press, including the density and moisture content of the leaf material, a final thickness of the
rim 50 at thelateral side 55 can vary to some degree. For instance, if thelateral side 55 is designed to be two millimeters thick, it might actually vary between 1.5 millimeters and 2.5 millimeters in thickness. Furthermore, after thedish 10 has been formed, in a process that involves application of steam, heat and pressure, some degree of “memory” in the areca palm leaf or other material, or potentially structural characteristics of the leaf material itself (such as the degree to which some portions of the leaf material are able to absorb steam or not, and the orientation of the leaf material within the press) can cause the dish to warp somewhat after removal from the press. - Such warpage is typically hardly noticeable, but causes the
top side 56 of therim 50 to be less than entirely planar. Because this warpage is quite small, it is not visible in the drawings shown herein. While the warpage can involve only a single corner or side being higher or lower than other portions thereof, in other situations, two opposite corners might be elevated and two other opposite corners might be lowered with such awarped rim 50. Such awarped rim 50 might have a height differential between lower corners or sides and higher corners and sides which might vary one to two millimeters from each other. -
Lid 60 materials, such as vacuum moldable plastic materials, have a small amount of flexibility which can accommodate some degree of warpage or variability inrim 50 thickness. However, there are limits to the degree to which such lids can accommodate such warpage. Thus, to provide alid 60 which can attach todishes 10 which may have an unacceptably wide range of warpage or rim 50 thicknesses, theperimeter latch 100 of thelid 60 is configured to accommodate this variability. - In particular, the
perimeter latch 100 extends downwardly from lowermost portions of theside walls 90 to define both a lowermost and outermost portion of thelid 60. Thisperimeter latch 100 is generally vertical except where at least oneindentation 104 extends inwardly thereon and at a lowermost edge where ahorizontal tab 108 optionally but preferably extends outwardly therefrom. Importantly, anupper recess 102 is provided between theindentation 104 and upper portions of theperimeter latch 100. Alower recess 106 is provided below theindentation 104 which ends at thehorizontal tab 108 and the lower edge of theperimeter latch 100. - The
upper recess 102 has a particular height and depth. The height is measured between upper portions of the at least oneindentation 104 and upper portions of theperimeter latch 100. A depth of theupper recess 102 is generally similar to a depth of theindentation 104 extending laterally in from other substantially vertical portions of theperimeter latch 100. The at least oneindentation 104 is shown as a plurality of elongatediscrete indentations 104 with gaps therebetween in therectangular dish 10 ofFIGS. 1 and 5-7 . Thesquare dish 20 shows a more continuous single indentation within theperimeter latch 100 thereof. - The depth of the
upper recess 102 formed by the depth of theindentations 104 is carefully selected so that the perimeter size of therim 50 at thelateral side 55 thereof can snap past theindentations 104 and into theupper recess 102, and the process can be reversed by snapping thelateral side 55 of therim 50 out of theupper recess 102 for removal of thelid 60. In one embodiment, this depth of theupper recess 102 is provided at four millimeters by havingindentations 104 extend four millimeters inward from vertical portions of theperimeter latch 100. Theperimeter latch 100 can be positioned at a location which is two millimeters greater than a diameter of therim 50 at thelateral side 55. In this way, two millimeters of tolerance are provided which can accommodate variations such as thermal contraction and expansion differences between the material forming thelid 60 and thedish 10, while still having two millimeters of therim 50 held within and above theindentation 104 within theupper recess 102 of theperimeter latch 100. - The height of the
upper recess 102 is preferably sized to be greater than a typical maximum thickness of therim 50 at thelateral side 55. For instance, if thelateral side 55 could be as large as 2.5 millimeters, theupper recess 102 would have a height which is greater than 2.5 millimeters. In a most preferred embodiment theupper recess 102 has a height which is fifty percent greater than a maximum typical thickness of therim 50 at thelateral side 55. Thus, if a maximum typical thickness of thelateral side 55 of therim 50 is 2.5 millimeters, theupper recess 102 would have a height of 3.75 millimeters. In this way, theupper recess 102 both accommodates variability in thickness of therim 50 and also warpage of therim 50 to some extent. - In addition to accommodating warpage by oversizing of the
upper recess 102, thelid 60 can to at least a small degree warp along with thedish 10 so that theperimeter latch 100 can remain attached to thedish 10 at therim 50. Furthermore, thelid 60 can be sufficiently strong so that to some extent it can “de-warp” thedish 10 somewhat and still have theperimeter latch 100 of thelid 60 remain securely attached to therectangular dish 10, and also be readily removable and re-attachable to thedish 10 by a user. - In some instances, a
dish 10 will have arim 50 which is not warped and will have a thickness at thelateral side 55 of therim 50 which is not oversized. In such an instance, thelid 60 may exhibit a small amount of looseness, but the depth of theupper recess 102 is sufficiently great that such looseness is not sufficient for thelid 60 to come off of therim 50 of thedish 10, so that substantially all extremes of variability in the geometry of thedish 10 are accommodated by the configuration of theperimeter latch 100 of thelid 60. - The
perimeter latch 100 preferably has a substantially uniform configuration around an entire perimeter of thelid 60. However, most preferably acorner grip 110 is provided where ahorizontal tab 108 at a lowermost edge of theperimeter latch 100 extends further laterally than other portions of theperimeter latch 100, and is preferably located at a corner of thelid 60. Arib 112 is inboard and on top of thiscorner grip 110 which can add some rigidity to thecorner grip 110. Thecorner grip 110 provides a location where a user can grip thelid 60 and apply an upward force focused at this corner to separate theperimeter latch 100 from therim 50, so that thelid 60 can be removed from thedish 10. - Similarly, the
square dish 20 andsquare lid 70 accommodate removal of thesquare lid 70 by providing acorner relief 120 at a corner of thesquare lid 70. Thiscorner relief 120 is somewhat less rounded than other corners so that a user can insert a finger under thecorner relief 120 and grab therim 50 and then use the finger (or some tool such as a handle of a spoon, fork or knife) to pivot upwards and separate thesquare lid 70 from thesquare dish 20. Thecorner relief 120 andcorner grip 110 could be swapped for each other on the 10, 20 or different corners of adishes 10, 20 could be provided with either thecommon dish corner grip 110 or thecorner relief 120. To some extent, thecorner relief 120 can also provide a small amount of ventilation if desired for an interior of the 10, 20 beneath thedish 60, 70, such as to reduce condensation therein, but preferably sufficiently small to prevent flies or other flying insects from passing into this enclosure.lid - This disclosure is provided to reveal a preferred embodiment of the invention and a best mode for practicing the invention. Having thus described the invention in this way, it should be apparent that various different modifications can be made to the preferred embodiment without departing from the scope and spirit of this disclosure. When structures are identified as a means to perform a function, the identification is intended to include all structures which can perform the function specified.
