Definitions

  • the present invention relates to containers and, in particular, to a set of nestable containers.
  • Conventional waste receptacles e.g., for vehicles, include plastic bags that may be hung from a projection in the passenger compartment.
  • plastic bags typically are flaccid or flimsy and so don't present a convenient opening for deposit of trash
  • modern vehicles tend to have flat and/or smooth surfaces in the passenger compartment and so have fewer, if any, projections on which to hang a trash bag.
  • trash bags are disposable, they need to be replaced when full, which can occur relatively often, and, if they are reusable, they can become soiled and unsanitary.
  • Another conventional trash container is a rigid plastic container of a cylindrical or parallelepiped shape that is held in position by gravity, and is stabilized by a flexible saddle attached to its bottom wherein the ends of the flaps of the saddle are usually weighted to hang over a hump on the vehicle floor.
  • a rigid plastic container of a cylindrical or parallelepiped shape that is held in position by gravity, and is stabilized by a flexible saddle attached to its bottom wherein the ends of the flaps of the saddle are usually weighted to hang over a hump on the vehicle floor.
  • Permanent reusable containers are typically more expensive and require plastic liners or other liners for sanitary and cleanliness reasons. Plastic liners often stick to themselves and/or cling to the container, and so are difficult to install and secure in the permanent container. Because the liners are usually much less sturdy than is the container, it is not unusual for the filled liner to tear or burst when it is being removed and/or disposed of, thereby spilling its contents.
  • a set of nestable containers may comprise a plurality of nestable self-supporting containers each being open at one end and having a closed end, and adhering means for adhering the set of nestable containers to an object, wherein said adhering means is exposed when said plurality of nestable containers is nested.
  • a set of nestable containers may comprise a plurality of collapsed nestable self-supporting containers being of size and shape for being nested one in another, each of the collapsed nestable containers including an anti-jamming member extending into an interior thereof into which at least one other collapsed nestable container may nest.

  • a first or outer container 20 a has adhering means 40 on the exterior of the closed bottom end thereof.
  • a set or nest 10 may comprise a greater or lesser number of nestable containers 20 , as may be desirable and/or convenient.
  • Containers 20 a - 20 e of FIG. 1B comprise a nest or set 10 of five nestable frustro-conical-shaped containers 20 of which each has an open end and is of circular cross-sectional shape, and wherein containers 20 a through 20 e are the same size.
  • a first or outer container 20 a has adhering means 40 on the exterior of the closed or bottom end 26 thereof.
  • a frustro-conical-shaped container has a shape that is a section or a frustrum of a cone, typically the cone is cut in a plane perpendicular to the central axis of the cone.

  • Suitable adhesive tapes include, e.g., type 442 KW tape, which is a double sided tape with a rubber adhesive, available from 3M Corporation of St. Paul, Minn.
  • Suitable hook and loop fasteners include, e.g., a Velcro® fastener available from Velcro USA located in Manchester, N.H.
  • adhering means 40 adheres sufficiently to an object to support nest 10 in a desired position for use and is releasable so that container 20 a may be removed from the object.
  • the hook portion of a hook and loop fastener is suitable for releasably adhering nest 10 to carpet or fabric.
  • a tacky adhesive is suitable for adhering nest 10 to a smooth or non-smooth object, such as a floor or wall, as well as to a carpet, and is preferably of an adhesive type that does not leave a residue on the object when it is removed.
  • Adhering means 40 may be a sheet or layer or member of like size and shape to the bottom of container 20 a or may be one or more sheets or layers or pieces thereof that is/are smaller than the bottom of container 20 a .

  • adhering means 40 of any of the foregoing examples of adhering means may be provided as adhering means 42 on any one or more sides of container 20 a . Because each of containers 20 b , 20 c and so forth is desired to be easily removable from the nest or set 10 of containers 20 , none typically includes adhering means.
  • Set 10 of nestable containers 20 may be utilized in any one or more of a wide variety of environments and locations, e.g., on a horizontal surface such as a floor of a vehicle or of a home or of a business or other location and/or on a vertical surface such as a side or door panel of a vehicle or the wall of a home or of a business or other location, whereat containers 20 may be withdrawn from nest 10 .
  • nest 10 may be adhered to the floor of a vehicle and containers 20 may be utilized for holding trash or other waste material.
  • the inner container 20 f When the inner container 20 f is filled or other wise ready for disposal, it is removed from nest 10 and is disposed of whereupon the next container 20 e is now presented as ready to receive trash.
  • each of containers 20 f - 20 a may be used and disposed of, usually in sequence, until at last container 20 a is ready for disposal and is removed from the vehicle or other location. After the last container 20 a is used, container 20 a is removed from the object and a new nest 20 may be put into place.
  • nest 20 may be adhered to a wall, work surface or other surface convenient to a point of use by adhering means 42 from which location containers 20 are dispensed for use, e.g., as take-out food or beverage containers. While relatively smaller containers 20 may be utilized for waste collection and for food and beverages, relatively larger containers 20 may be utilized for larger capacity waste collection and other uses, e.g., in a home or business location.
  • FIGS. 2A-2D are schematic diagrams of various example shapes of a container 20 of the set 10 of containers of FIG. 1A and 1B.
  • Containers 20 R and 20 R′ of FIGS. 2A and 2B are generally parallelepiped-shaped having, for example, four generally rectangular sides 22 defining a rectangular cross-section, a rectangular open end 24 and a rectangular closed or bottom end 26 .
  • Container 20 R of FIG. 2A is rectangular and a set 10 of containers 20 R comprises a plurality of nestable containers 20 R of like shape but that are of different cross-sectional dimension, from a larger container 20 R to a smaller container 20 R, so as to nest one with another.
  • Containers 20 R may be of the same or of different dimension between their open end 24 and closed end 26 .
  • Container 20 R′ of FIG. 2B is also rectangular in cross-section, but is tapered between its open and closed ends 24 and 26 , having, for example, four trapezoidal sides 22 defining a rectangular cross-section, a rectangular open end 24 and a rectangular closed or bottom end 26 .
  • Container 20 R′ is a frustrum of a pyramid, e.g., a four-sided pyramid or a tetrahedron.
  • a set 10 of containers 20 R′ comprises a plurality of nestable containers 20 R′ of like shape and size, wherein the smaller closed end of one fits into the open end 24 of another, so as to nest one with another.
  • Containers 20 R′ may be of the same or of different dimension between their open end 24 and closed end 26 , but are typically of the same dimension.
  • containers 20 R and 20 R′ are shown as having four sides by way of example, any number of sides greater than or equal to three may be employed, as may be desired. Typically, four sides of like size are employed, although other numbers, such as six or eight, may be employed. As described below in relation to FIGS. 4A-4B and 5 , for example, modifications to a four-sided container may be employed wherein the container has four major or relatively large sides and one or more relatively small or minor sides.
  • Containers 20 C and 20 C′ of FIGS. 2C and 2D are generally cylindrical-shaped having, for example, curved sides 22 defining a circular cross-section, a circular open end 24 and a circular closed or bottom end 26 .
  • Container 20 C of FIG. 2C is cylindrical and a set 10 of containers 20 C comprises a plurality of nestable containers 20 C of like shape, but that are of different diameter from a larger diameter container 20 C to a smaller diameter container 20 C, so as to nest one with another.
  • Containers 20 C may be of the same or of different dimension between their open end 24 and closed end 26 .
  • Container 20 C′ of FIG. 2D is a tapered cylinder or a frustrum of a cone and a set 10 of containers 20 C′ comprises a plurality of nestable containers 20 C′ of like shape and size, e.g., each has the same larger diameter at the open end 24 thereof and has the same smaller diameter at the closed end 26 thereof, so as to nest one with another.
  • Containers 20 C′ may be of the same or of different dimension between their respective open ends 24 and closed ends 26 .
  • FIG. 3 is a cross-sectional view schematic diagram of an example set 10 of nestable containers 20 in a nested condition, wherein the example containers 20 may be of the sort illustrated in relation to container 20 ′ a - 20 ′ e , 20 R′ or 20 C′ described above.
  • Containers 20 a - 20 c are nested and ones thereof may be removed from the nest 10 , preferably with relative ease. In using nest 10 , however, one typically presses down on the open end of nest 10 , e.g., on the edge of side 22 at the open end 24 of the innermost container 20 c or of containers 20 c - 20 b in pressing nest 10 to adhere adhering means 40 to an object.
  • This force applied for adhering nest 10 to an object also tends to press the containers 20 thereof into each other and as a result they may become “stuck together” or “jammed.”
  • “jam” and “jammed” and “jamming” refer to the condition wherein nested containers become pressed together to the extent that they are more difficult than desired to separate one from another. This effect may be more pronounced where containers fit very closely together, e.g., so closely that they stick together, or where a person perceives that pressing the nest of containers harder against the object will result in a more secure attachment, even if that is not true.
  • Jamming may result from friction between adjacent nested containers or by a partial vacuum created when a container is withdrawn from within another container with which it closely fits, or from a combination thereof. It is noted that the object to which a nest of containers may be adhered may be relatively smooth or relatively non-smooth or of in-between smoothness, or may be a combination thereof, and/or may be relatively hard or relatively soft or of in-between hardness, and/or a may be a combination thereof.
  • set or nest 10 may desirably be provided with one or more anti-jamming means or features.
  • anti-jamming refers to any way to avoid, minimize, reduce and/or eliminate jamming, whether due to friction, pressure difference and/or other cause.
  • anti-jamming means or features may break the close fit of containers that would otherwise fit very closely together, thereby to make separating the nested containers easier.
  • Anti-jamming means or features for containers 20 b and 20 c of FIG. 3 may include, for example, one or more holes 27 in the respective bottoms 26 of containers 20 for providing a passage for relieving reduced pressure that otherwise might occur when container 20 c is being removed from within container 20 b and when container 20 b is being removed from container 20 a . It is noted that any one or more anti-jamming means or features may be employed on any given container and/or nest, and need not be the same for all containers of a nest 10 of containers, although it is expected that similar anti-jamming means or features are likely to be provided for the containers of a given nest 10 .
  • FIGS. 4A and 4B are an isometric view and a top view schematic diagram, respectively, of an example embodiment of a container 20 D having anti-jamming means or features 23 for a set of nestable containers 20 D.
  • anti-jamming means 23 includes a smaller side that is disposed at a diagonal, e.g., at a 45° angle, between two adjacent sides 22 at one corner of container 20 D, and so may be referred to as a “cut corner” 23 .
  • container 20 D is a rectangular parallelepiped
  • small side 23 is rectangular as are sides 22 .
  • container 20 D is a tapered parallelepiped
  • small side 23 is trapezoidal as are sides 22 .
  • FIG. 5 is a top view schematic diagram of a nest 10 including the example embodiment of a cut-corner nestable container 20 D of FIGS. 4A-4B having anti-jamming means or features.
  • Each cut corner 23 provides a passage for relieving pressure with the container 20 nested inside container 20 D and with the container 20 in which container 20 D is nested.
  • Cut corner panel 23 of container 20 Db provides a passage between container 20 a and 20 Db and between container 20 Db and container 2 ODc.
  • Container 2 ODc provides a passage between container 2 ODc and container 20 d .
  • container 2 ODe provides passages between container 2 ODe and containers 20 d and 20 e . While every container 20 could be a cut-corner container 20 D, such is not necessary for effective anti-jamming.
  • various non-adjacent ones of containers 20 D may be oriented in like orientation so that the cut corners 23 thereof are at the same corner of nest 10 , as are containers 2 ODc and 2 ODe, or they may be in different orientations, as are containers 20 Db and 2 ODc, and still provide effective anti-jamming means.
  • the sequence of different orientations of containers 20 D may be repetitive and/or regular, or may be non-repetitive and irregular. In other words, the orientation of containers 20 D in nest 10 simply doesn't matter with respect to anti-jamming, i.e. providing a passage for relieving reduced pressure, so long as every other container 20 is a container 20 D having a cut corner panel 23 .
  • each container 20 , 20 D is tapered having a top opening that is about 12.7 cm (about 5 inches) square and a closed end (bottom) that is about 11.5 cm (about 4.5 inches) square, having a height of about 15.25 cm (about 6 inches), with a cut corner panel at a 45° angle with a dimension of about 1.25 cm (about 1 ⁇ 2 inch) at top opening 24 and about 1 cm (about 0.4 inch) at bottom 26 .
  • Typical waste containers 20 , 20 D for vehicles are about 10-13 cm (about 4-5 inches) square or about 10-13 cm (about 4-5 inches) in diameter at the open end 24 , and are about 15-20.5 cm (about 6-8 inches) deep, and typically have a taper of about 1-1.5 cm (about 1 ⁇ 2 inch) on each side.
  • Typical waste containers 20 , 20 D for home or business use are about 25 by 14 cm (about 10 by 5.5 inches) rectangular at the open end 24 , and are about 25 cm (about 10 inches) deep, and typically taper to a closed end of about 22.9 by 11.4-12 cm (about 9 by 41 ⁇ 2-43 ⁇ 4inch) on each side.
  • Suitable materials for containers 20 , 20 D, and any other container of the sort described herein include lightweight paperboard (e.g., about 120-130 pound weight paperboard), cardboard, corrugated cardboard (e.g., especially for containers of larger size), plastics, such as polyethylene, polypropylene, polystyrene and the like, and thin aluminum, such as that utilized for disposable cookware.

Where flap 25 is folded outside of container 20 G and is glued or otherwise adhered to the exterior surface of adjacent side 22 to form a corner, the thickness of tab 25 will define a space between container 20 G and a container 20 into which container 20 G is placed through which air may flow to relieve pressure differences, thereby to provide anti-jamming means.
  • tabs or flaps 25 extending from each of two adjacent sides 22 at a corner of container 20 G′ are folded and glued or otherwise adhered to each other to form a fin seam at a corner of container 20 G′.
  • Glued or adhered tabs or flaps 25 may extend outwardly from container 20 G′ of FIG. 6B, as illustrated, or may extend inwardly into the interior of container 20 G′. Due to the extension of the fin seam formed by glued tabs 25 , an anti-jamming means in the form of a space through which air may flow to relieve pressure differences will remain between container 20 G′ and an adjacent nested container 20 and/or friction therebetween is reduced.

  • an adhesive strip is provided on the exterior surface of the closed end along the central seam in the direction of the longer dimension thereof, and in other example containers two parallel adhesive strips are provided on the exterior surface of the closed end adjacent the longer edges thereof.
  • the length dimension of the adhesive strip(s) is substantially the full dimension of the closed end, but may be shorter, if desired.
  • FIG. 12 is a schematic diagram of a cut-out blank 20 BL-RC of sheet material for forming a nestable container 20 having a closure.
  • the dashed lines indicate fold lines, and the fold lines are preferably scored for easier and more precise folding.
  • Cut-out blank 20 BL-RC is identical to any one of cut-out blanks 20 BL-R, 20 BL-R′, 20 BL-R′′ described above (i.e. it may or may not include optional features 221 , 22 P and/or 22 T), except that it includes closure means 124 for open end 24 of container 20 .
  • Closure means 124 comprises, for example, four cover flaps 124 a , 124 b extending from the edges of sides 22 that would otherwise define the open end 24 of container 20 .
  • One cover flap 124 a includes a tab 125 extending from the shorter edge thereof that when folded is glued or otherwise adhered to the shorter edge of cover flap 124 b most distal therefrom, so that when blank 20 BL-RC is folded to form container 20 , cover flaps 1214 a , 124 b extend from sides 22 and substantially in plane therewith.
  • Cover flaps 124 a , 124 b are preferably scored where they join sides 22 and where they join each other.
  • smaller cover flaps 124 b extending from smaller sides 22 have additional scored lines extending diagonally from the intersection of the score lines between cover flaps 124 a and 124 b and the score lines between cover flaps 124 a , 124 b and sides 22 .
  • the diagonal scored lines converge and end proximate each other at the edge of cover flaps 124 b for defining a gripping region 124 c thereat.
  • cover flaps 124 a move inward to cover the open end 24 of container 20 while cover flaps 124 b move outward and fold along the diagonal score lines.
  • gripping regions 124 c have been moved to about the plane defined by the score lines defining open end 24
  • cover flaps 124 a are substantially co-planar to cover the open end 24 of container 20 and cover flaps 124 b have folded along the diagonal score lines to be triangular.
  • Folded cover flaps 124 b may then be folded against side 22 and the apex of triangular-folded cover flaps 124 b may be inserted into die-cut slit 22 s provided therein, whereby cover flaps 124 b are held in the folded position which holds cover flaps 124 a covering the open end 24 of container 20 .
  • FIG. 13 is an isometric view schematic diagram of a nestable container 20 in a partially folded or collapsed condition
  • FIGS. 14A, 14B and 14 C are top, side and bottom view schematic diagrams, respectively, of nestable container 20 in a folded or collapsed condition.
  • Folding or collapsing container 20 is desirable to reduce the volume it occupies, e.g., during storage and shipping.
  • containers 20 may be expanded to an un-collapsed condition for use either before or after being withdrawn from the nest of containers.
  • the illustrated container 20 is generally rectangular and may have tapered sides, similar to the containers illustrated, for example, in FIGS. 1A, 2A, 2 B, 3 , 4 A- 4 C, 5 , 6 A- 6 B, 8 D- 8 H, 11 A- 11 D and 12 .
  • a stack or nest of collapsed containers 20 may be utilized in its collapsed condition with individual containers un-collapsed or the stack or nest of collapsed containers 20 may be expanded or un-collapsed so that each of the containers 20 thereof is in its expanded condition prior to using or withdrawing any container 20 of the stack or nest thereof.
  • Container 20 has four generally rectangular sides 22 and a rectangular closed end 26 .
  • sides 22 are slightly trapezoidal so that container 20 is slightly tapered, being smaller at closed end 26 than at open end 24 .
  • Closed end 26 comprises four flaps 26 a , 26 b that are folded and glued.
  • flaps 26 b each have a tab 26 T that is folded inward to provide an anti-jamming feature at the interior of closed end 26 .
  • Container 20 is collapsed or folded by folding closed end 26 inwardly (as indicated by the arrows pointing upward from dashed line 226 in FIG. 13) and folding opposing sides 22 outwardly (as indicated by the arrows pointing to the left and right from lines 222 in FIG. 13), substantially at the same time.
  • closed end 26 is preferably folded along a line in a direction parallel to the lengths of tabs 26 T if tabs 26 T are provided.
  • the fold 226 in closed end 26 is along a line parallel to and in between the two anti-jamming tabs 26 T, as is preferred where anti-jamming tabs 26 T are provided.
  • Two opposing sides 22 are each folded in an outward direction along a respective fold line running in the direction between closed end 26 and open end 24 at respective folds 222 , thereby defining partial sides 22 a and 22 b on opposite sides of fold 222 .
  • Fold 226 meets respective folds 222 at respective locations 223 on opposing sides 22 part way between closed end 26 and open end 24 .
  • folds 222 and 224 in each of sides 22 together define a “Y” shaped fold therein, wherein the “Y” is inverted when closed end 26 is the downward or bottom of container 20 , i.e. the top of the “Y” is at closed end 26 and the central leg of the “Y” is at open end 24 .
  • Container 20 is typically made by folding a container blank 20 BL at its score or crease lines into the shape of container 20 and gluing or other wise securing tab 25 to side 22 and closed end flaps 26 a , 26 b in proper position. Then container 20 is folded or collapsed by folding outwardly along lines 222 , 224 and inwardly along line 226 . Any one or more or all of folds 222 , 224 , 226 may be made along scored, creased or embossed lines of blank 20 BL. Plural containers 20 so made and collapsed are then nested to provide a nest of containers.
  • both the outward folding of opposing sides 22 along fold lines 222 , 224 , and the inward folding of closed end 26 along fold line 226 are done together, i.e. substantially contemporaneously.
  • the collapsed container 20 will tend to spring open or expand slightly from the collapsed state, which may be advantageous in placing collapsed containers 20 into a nested arrangement of containers.
  • a set of nested containers 20 may be packed in a box or other container, or may be over wrapped by plastic or other packaging material, e.g., for shipping, storage, and/or for retail display, and the packaging material may tend to maintain containers 20 in the collapsed condition until they are unwrapped and put into use.
  • FIG. 15 is a cross-sectional view schematic diagram illustrating two of the nestable container 20 of FIGS. 14A, 14B and 14 C in nested arrangement.
  • the inner or top one of the containers 20 is designated 20 b and the outer or bottom one thereof is designated 20 a .
  • any number of containers 20 may be nested as may be convenient or desired, however, two are illustrated by way of example for illustrating the relative arrangement of the features interior thereto.
  • anti-jamming tabs 26 T of container 20 a bear against the exterior of closed end 26 of container 20 b to maintain space therebetween, thereby to facilitate and ease separation of containers 20 a and 20 b in use.
  • the tendency of containers 20 a , 20 b to spring back or expand slightly from the collapsed condition may also tend to ease the removal of containers 20 from the nested stack thereof.
  • Container 20 a may include adhesive or other adhering means 40 on an outside surface thereof, e.g., on the outer surface of closed end 26 , e.g., on outer flaps 26 a .
  • adhesive or adhering means may include any form and/or material, e.g., as described herein.
  • Such adhesive or adhering means may be provided on containers 20 of a nest of containers in addition to the exposed container, and may be of sufficient thickness as to resist the jamming of containers 20 in a nest 10 of containers 20 .
  • the inward fold of the closed end 26 of container 20 as described be made in a direction that permits any anti-jamming means associated with closed end 26 , e.g., tabs 26 T, to provide anti-jamming when container 20 is in the folded condition. It is noted that any of the example anti-jamming arrangements described may be employed where the container is folded or collapsed.
  • FIGS. 14A-14C and 14 are container(s) 20 corresponding to the container blank 20 BL-RT shown in FIG. 11D
  • the folding arrangement and method described may be employed with containers 20 corresponding to the container blanks 20 BL shown in any of FIGS. 10 , 11 A- 11 D and 12 , and/or with other containers described herein, as well as with containers not described herein.
  • the term “blank 20 BL” is employed to refer to any or all of example container blanks 20 BL-C, 20 BL-R, 20 BL-R′, 20 BL-R′′, 20 BL-RT, 20 BL-RC, as well as to blanks not illustrated.
  • the term “about” means that dimensions, sizes, formulations, parameters, shapes and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art.
  • a dimension, size, formulation, parameter, shape or other quantity or characteristic is “about” or “approximate” whether or not expressly stated to be such.
  • an adhesive is provided as the adhering means
  • the adhering means preferably has stronger adhesion to the material of the container than to the object to which the nest of containers adhere.
  • one or more strips or patches of hook and loop fastener having adhesive on one side thereof for adhering to the container may be employed, as may be one or more strips or patches of adhesive tape comprising two or more layers, e.g., one layer that adheres strongly to the container material and another layer that adheres releasably to the object.
  • Other adhering means may also be employed.
  • a sheet magnet material such as a plastic or rubber sheet having magnetized material and/or particles therein, of the sort that is used for “refrigerator magnets” may be adhered to container 20 intended to be mounted to an object of iron, steel or other material attracted to a magnet.
  • Adhering means may be provided as one or more strips or patches of adhesive, hook and loop fastener and/or any other suitable adhering material, or as a sheet thereof. On the other hand, adhering means could be omitted from one, some or all of the containers.
  • nest of nestable containers described may be utilized for containing any other material in place of and/or in addition to waste, such as food, beverage, and at any point of sale or distribution, in sizes either larger or smaller than the typical sizes described.
  • number of containers in a nest may vary over a wide range, e.g., from about 5-8 containers for typical vehicle and/or home and/or business uses, and to greater or lesser numbers for these and/or other uses.
  • adhering means While an adhering means is typically to be provided on an exterior surface of only the outermost container of a stack of containers, it may be desirable to provide adhering means on other ones and/or on all of the containers of a stack of containers. This may simplify manufacturing because all containers may be the same, or may be advantageous for a particular use thereof.
  • the adhering means be it an adhesive or a hook and loop fastener, may be of sufficient thickness to resist jamming of plural nestable containers when the plural nestable containers are nested. If the adhering means is adhesive, a release liner or other peelable covering may be provided, as is typical for the adhesive adhering means herein.
  • One example of such particular use could be where food is dispensed to a person likely to consume the food aboard a moving and/or movable conveyance, such as a train or airplane.
  • the adhering means could be employed to attach the container to a seat tray or other surface, e.g., whether the container is utilized as a holder for food to be consumed or as a holder for another a food tray or plate, whereby the container would not slide around while the person was attempting to consume its contents.
  • nestable containers described are generally glued or otherwise adhered together from a folded blank or from plural pieces of flat material to form a container
  • nestable containers that are only folded may also be nestable as described herein, and may be provided in a set or nest with adhering means and/or anti-jamming means or features as described.
  • Such containers might find use, for example, as food containers wherein food is dispensed in a folded nestable container, e.g., one with a closure as described, is opened and unfolded to serve as a plate or place mat when consuming its contents, and may then be refolded to serve as a waste container.
  • closures such as the slot and tab type of closures provided on conventional cereal and cracker boxes, may be utilized with the nestable containers described herein, or separate lids, e.g., lids that are themselves nestable containers as described herein, may be utilized.
  • containers are described herein as being “nestable,” or being “nested,” or being a “nest” of containers, i.e. for being or being capable of being placed one into another, which Applicant's consider a preferred terminology. Such arrangements may also be referred to as being “stackable,” or being “stacked,” or as being a “stack” of containers within the scope of the claims following.
  • inward and outward generally refer to a direction as would be perceived from the vantage of a person observing or using such container, i.e. inward is towards the interior of the container, e.g., the volume defined by the side or sides and the closed end thereof.
