Definitions

  • the invention is directed to columns, trays and systems comprising columns and trays, as well as to bails for engaging conventional trays, that enable a person to conveniently and safely transport objects, such as one or more beverage containers, by tension (hanging) as opposed to compression (supporting).
  • the invention provides a means for establishing the center of gravity for the tray below a user's hand(s), thereby dramatically increasing its stability and portability.
  • the means comprises an auxiliary structure having a hand gripping portion for facilitating handling by a user and a tray engaging portion for supporting a tray, either apertured or conventional.
  • the invention comprises on the one hand an auxiliary structure that engages with a primary tray to permit one-handed transportation of items contained in the primary tray, and on the other hand a primary tray having a generally centrally located aperture for receiving an auxiliary structure.
  • the components of the invention may be constructed from a planar or non-planar material such as plastic, corrugated cardboard, chip board or other cellulose-based material, or acetate sheet; alternatively, it may be cast or molded from a slurry, particularly including cellulose pulp.
  • the former are referred to as "constructed" columns while the later are referred to as "molded” columns. While each material has its benefits, greatest economies can be realized through the use of molded pulps.
  • the auxiliary structure comprises an elongate column adapted to extend from a central portion of a primary tray, which is adapted to receive the column.
  • the invention comprises a bail-type member that engages at least two sides of an unmodified primary tray.
  • the tray defines an aperture to receive a column.
  • the first series of embodiments comprise a column extending from a central portion of a primary tray.
  • the column may be formed integral with the tray, or may be permanently or non-permanently attached to the tray.
  • the primary tray and the column are co-formed to create a unitary structure, and are preferably constructed by a molding process.
  • adhesives are preferably used to modify a removable column to ensure the structural integrity of the overall assembly; modification of a conventional tray is not necessary although it may be desirable.
  • a suitable tray will have at least an aperture formed therein for receiving the desired column, the aperture preferably having or caused to have a cross section shape or geometry that closely matches that of the column cross section at the interface between the two components, as will be discussed in greater detail below.
  • the column may have a closed curve cross section, e.g., circular or elliptical, or may be an n-sided polygon in cross section, e.g., triangular, square, pentagonal, etc.
  • an appropriately formed aperture is either designed into the primary tray (created at the time of tray formation) or results from post formation modification.
  • the post formation aperture may be established by removing a central portion of the tray, e.g., an outline perforation may be created in the tray whereby removal thereof can be accomplished "punching" the central portion or by perforating a pattern such as an "X", which will create an approximate square aperture.
  • the waste from the removal process can be used to maintain an expanded state after engagement of the column with the tray.
  • the cross section of the column is selected to substantially mate with the geometry of the aperture defined by the primary tray, or vice versa. If the column is a regular or right cylinder, then the external dimensions of the column should closely match those of primary tray aperture; if the column is tapered in general or frusto-conical in particular (either closed curve or n-sided polygon in cross section), then that portion of the column intended to interface with the primary tray during use should have external dimensions and a geometry close to that of the primary tray aperture.
  • a feature of the invention provides for the inclusion of at least one aperture collar positioned about the perimeter of the aperture.
  • An aperture collar increases the amount of area surface area contact between the column and the tray, and further distributes the torque moment between these two components over a greater area, thereby increasing tray stability.
  • the at least one collar can be established on the upper surface of the tray or on the lower surface.
  • a tray will have both upper and lower collars.
  • At least one primary tray supporting element may be provided at a lower portion of the column to prevent over-extension of the column through the aperture and to distribute localized vertical column load across the tray.
  • This at least one lower supporting element beneficially engages with the bottom of the tray and, therefore, prevents further translation of the column through the tray and distributes vertical load across a greater area of the primary tray.
  • the column may further comprise at least one upper retaining elements that beneficially engage with an upper surface of the tray, thereby preventing unintended downward translation of the column once engaged with the tray. The incorporation of upper retaining elements further increase the stability of tray relative to the column by arresting undesired torquing of the tray, such as would be encountered during transportation of asymmetrical loads.
  • tapered column embodiment relies upon a similar friction interference between the column and the primary beverage tray.
  • a plurality of laterally oriented slots are selectively formed in the column.
  • a non-circular cross section column is used (preferably one that has corners which have a maximum diameter greater than that of the minimum diameter of the tray aperture).
  • the slots will engage with the peripheral portions of the tray aperture when the column is inserted into the aperture, the slots are brought coplanar with the peripheral portions of the aperture, and the column is rotated relative to the primary tray, thereby providing suitable support means without the use of discrete supporting elements.
  • the column was preferably rigid. However, if a lateral slot arrangement is to be used, a modification is to provide a collapsible lower portion in the column. In this embodiment, rotation of the column to engage the peripheral portions of the tray aperture is not needed. Instead, the collapsed portion of the column is inserted into the aperture where after the column is fixedly expanded. In a disclosed embodiment, the expansion is accomplished by introducing a stiffening member into the area defined by the column.
  • the stiffening member is preferably a wall portion of the column that is pivoted inwardly in the direction of column collapse, until it contacts the opposing wall portion, thereby causing the same to project outwardly.
  • Both of the preceding embodiment series also preferably include a gripping means for providing a location for a user to grasp or retain the column.
  • the gripping means may be a handle member insertable into the column, i.e., an auxiliary structure not integral with the column, or may be a handle member integral with the column, i.e., cut from a blank during formation of the column or molded with the column.
  • the handle member can be laterally inserted into a pair of aligned holes, or can be inserted through a slot depending from the top of the column where after an obstructive interface prevents reverse movement.
  • the insertable handle member can be a simple "V" shaped insert, or a conventional handle formation, including obstructive interface features.
  • the handle member can also be fixedly attached to the column, such as by mechanical fasteners and/or adhesives.
  • the handle member can employ a bail having two opposed distal ends that are inserted or otherwise grip the column.
  • the gripping means can take the form of positive and/or negative relief features formed on the outer surface of the column, or can take the form of a hole through which a user may insert a finger or other object.
  • a feature of select embodiments regarding the columns includes the use of tapered columns.
  • tapered columns By utilizing tapered columns, a plurality of columns can be stacked and nested into one another, thereby reducing overall space necessary for transportation and/or storage of assembled columns, with or without attached trays.
  • a tapered geometric form beneficially facilitates the insertion of the column through the aperture of the tray and permits reliance on a friction fit between the column and the tray, whether or not other means for securing the relationship between the components are used.
  • the secondary tray includes an aperture of sufficient dimensions and geometry to permit a column to penetrate there through. If secondary tray supporting elements are present on the column, the secondary tray supporting elements can arrest undesired translation between the secondary tray and the primary tray, thereby creating a suitable support surface for carrying items in addition to those carried by the primary tray. If a tapered column is used, then the dimensions of the second tray aperture should be such that the secondary tray does not translate the entire length of the column, but is frictionally restricted from further translation at a location generally corresponding to the maximum dimensions of the second tray aperture.
  • secondary tray upper retaining elements may be provided that beneficially engage with an upper surface of the secondary tray, thereby preventing unintended upward translation of the secondary tray relative to the column once engaged with the secondary tray.
  • the incorporation of secondary tray upper retaining elements further increase the stability of tray relative to the column by arresting undesired torquing of the tray, such as would be encountered during transportation of asymmetrical loads.
  • a secondary tray In addition to or in lieu of a secondary tray, additional accessories can be linked to the column.
  • a tether member comprising a loop portion and a carrier portion.
  • the loop portion defines an aperture akin to that of the secondary tray to provide a friction fit between it and the column, and further includes a tether portion linking the loop portion with a carrier portion.
  • pairs of these tether members are used to form a "saddle" configuration.
  • a column can also be modified to accept beverages in addition to those being held by the beverage tray, or replace the function of the beverage tray as will now be described.
  • additional objects such as beverage cups
  • a generally linear strip of material having two distal ends is formed so that upon envelopment of an object and overlapping attachment of the distal ends, a hook structure for the object is formed.
  • a preferred means for attachment of the strip uses a latex-based cohesive such as that manufactured by Sovereign Chemical of Cincinnati, Ohio. The cohesive will only bond to itself, but create a high coefficient of friction with the object.
  • the hook structure has a length greater than that of the at least one slot; only pivotal insertion of the hook structure into the slot will engage the overlapped strip of material with the column. By positioning the distal end of the hook upward, downward pivoting of the structure will not cause the structure to emerge from the slot. Thus, the hook structure extends into the at least one slot and thereby retains any object placed therein to the column.
  • Other embodiments use a similar sliding engagement for retaining an auxiliary structure in a slot formed in the column, as will be appreciated by those skilled in the art.
  • the auxiliary structure is a bail member that provides support for the primary tray, which need not be modified in order to operate with the invention.
  • the auxiliary structure comprises at least two peripheral support members that extend beyond the lateral sides of the primary tray and further extend inwardly toward the center of the tray (forming a handle segment) to provide a suitable support means for the tray. While this configuration provides suitable single axis support, it does not address orthogonal movement of the primary tray. Consequently, laterally extending stabilizers arrest the second axis rotation by preventing rotation about the axis defined by the two retention members.

  • a conventional disposable beverage tray of the prior art is shown.
  • Tray 10 includes upper surface 12, lower surface 14, container recesses 16 formed in upper surface 12 and central portion 18.
  • up to four beverage containers are disposed in recesses 16 and a user carries tray 10 by supporting lower surface 12.
  • the center of gravity for the tray is above the point of support, thereby inherently creating an unstable platform.
  • an auxiliary structure is needed. As best shown in Figs. 2-4, the auxiliary structure comprises column 40, which is used in conjunction with modified tray 20.
  • Tray 20 resembles tray 10 in all material respects (upper surface 22, lower surface 24, container recesses 26 and central portion 28) except for the presence of aperture 30.
  • aperture 30 has sides 32a-d, which are established such that they approximate the geometric shape of column 40 at the point of contact (see Fig. 3).
  • Column 40 includes upper end 42, lower end 44 and sides 46a-e.
  • supporting elements 60 are used.
  • supporting elements 60 comprise flaps 62a- d, each of which includes supporting edge 64.
  • Column 40 can be die cut from a suitable material such as fiber board, corrugated or folding paperboard as is shown in Fig. 4, and assembled into a final form such as shown in Fig. 2 by folding each side 46 until side 46a is overlapped by side 46e.
  • the assembled structure can be biased to retain its shape through the radial constriction of aperture 30 when column 40 is inserted there through, via mechanical fastening between side 46a and 46e, or adhesive bonding between side 46a and 46e.
  • supporting elements 60 comprise flaps 62a-d.
  • Each flap 62 includes supporting edge 64, which contacts lower surface 24 of tray 20 when column 40 is fully inserted into aperture 30 and flaps 62a-d are extended as shown.
  • handle recesses 50 are provided.
  • handle recesses 50a-c longitudinally align to form slots 52a and 52b.
  • each recess 50 includes converging edges 54a and 54b, and retaining edges 56a and 56b.
  • the configuration of recesses 50 is selected to exploit the geometry of handle 80.
  • handle 80 includes sides 82a and 82b, each side having corresponding supporting edges 86a and 86b.
  • handle 80 is inserted into recesses 50, either vertically through slots 52 or laterally as shown in Fig. 2, sides 82a and 82b abut converging edges 54a and 54b, respectively.
  • Vertical escapement of handle 80 is prevented by the interaction between supporting edges 86a and 86b with retaining edges 56a and 56b, respectively. This interaction is best shown in Fig. 3.
  • Column 140 shown in Figs. 5-7, is similar to column 40 shown in Figs. 2-4, except that in addition to lower supporting elements 60, it includes upper retaining elements 70, which comprise flaps 72a-d.
  • Each flap 72 includes contacting edge 74, which functions to restrain upward vertical movement of tray 20 relative to column 140, as best shown in Fig. 7. Because flaps 72a-d must be in the non- extended position during insertion of column 140 into tray 20, these flaps must be extended prior to realizing their functionality. When so extended after column insertion through the aperture, perimeter 32 is generally compressively held between supporting edges 64a-d and contacting edges 74a-d, as is best shown in Fig. 7.
  • handle 180 Also shown in use with column 140 is handle 180. While the functionality of handle 180 is similar to that of handle 80, it further comprises central body portion 184, which serves to link side 182a with side 182b, and to provide finger hole 88. As with handle 80, supporting edges 182a and 182b cooperate with retaining edges 156a and 156b.
  • FIG. 8 shows column 140 engaged with tray 20, and further illustrates secondary tray 90.
  • Secondary tray 90 is intended to provide a means for exploiting the presence of any column by providing support for items in addition to those that may be carried on the primary tray. While tray 90 need only have aperture 92, enhanced stability can be achieved by incorporating a collar surrounding aperture 92 (the collar concept will be explored in more detail with reference to Figs. 24-26), lower and optionally upper supporting elements similar in concept to supporting elements 60 and retaining elements 70 of columns 40 and 140, and equivalent stabilizing structure.
  • vertical translation of secondary tray 90 is uni-directionally limited, with or without the presence of supping elements as long as the column has a taper. In those embodiments wherein a right prism form is selected, then some form of supporting elements on the column is necessary. Furthermore, by modifying the shape or footprint of the secondary tray, sufficient clearance can be retained for carrying tall beverage containers.
  • FIG. 9-13 support for the tray is accomplished by slots formed in the column.
  • Lower supporting elements 260 comprise lateral slots 248a-d, which are formed at each corner of column 240. The lateral width of each slot will determine the degree or extent of interaction with tray 20.
  • Column 240 is inserted into aperture 30 of tray 20 as conventionally shown in prior embodiments, however, support is not achieved by friction fit or extension of flaps. Instead, and as best illustrated in Fig.
  • column 240 is rotated within aperture 30 such that each lateral slot 248 engages perimeter 32 of aperture 30 (shown by arrows).
  • this mode of support also provides the equivalent of upper supporting elements as will be appreciated by those persons skilled in the art.
  • FIG. 11-13 depict a variant of the above-referenced alternative embodiment.
  • column 340 is collapsible in at least one direction and elongate lateral slots 349a and 349b are present on the faces of the column subject to the direction of collapse, and extend into the adjacent faces to limit the degree of tray support.
  • flap 394 is formed in one of the faces of the column having the elongate lateral slot.
  • a non-collapsing structure can be achieved (flap 394 functions as a brace or compression strut with tab 496 operating to retain flap 394 in the desired position).
  • the recess created by these actions provides a convenient location for the storage of incidentals of the user's choice.
  • FIG. 11 and 12 also illustrate an additional handle embodiment.
  • handle 480 comprises extending sides 482a-d, which derive from sides 446a and 446c.
  • Slits 486 decouple sides 482 from sides 446 so that when sides 446b and 446d are compressed towards each other (direction of arrows), sides 482 can extend as shown in beginning in Fig. 11 and ending in Fig. 12.
  • a coating of a cohesive between the mating portions of sides 482 or use of other means for fastening these sides can be used to prevent subsequent separation thereof.
  • Figure 14 is shown as an example of a true conical column that relies exclusively on friction fit with tray 520, although any of the heretofore described means for linking the column to the tray can be used.
  • tray 520 has modified aperture 530, which comprises two orthogonal scores or perforations 532a and 532b.
  • This frangible aperture is then established upon the insertion of the column through the aperture, whereupon flaps 534a-d will upwardly extend, thereby forming a type of collar about the column.
  • This collar beneficially increases the surface contact area between the two structures, which increases the coefficient of friction there between.
  • the extension of flaps 534a-d in an upward direction further increases the resistance of the column to "downward" movement. It should be noted that this interaction is valid for any form of column, including those previously described and those to be described.
  • FIGS. 15-17 disclose the use of beverage rings 610 with elongate vertical slots 648, which may be formed towards upper end 642 or lower end 644 of column 640.
  • Each ring 610 comprises inside surface 612, outside surface 614, and distal ends 616, which include hook portion 618.
  • At least inside surface 612 of each hook portion 618 will be securely linked to each other either intrinsically such as through the use of adhesives, cohesives, mechanical fasteners or the like, or extrinsically such as through the mutual insertion of hook portions 618 into elongate vertical slot 648. Once so linked, a cylindrical or frusto-cylindrical ring is formed, ready to accept a beverage container.
  • ring 610 functions to stabilize a container disposed in a cup recess; this is particularly advantageous when carrying large volume beverage containers that have a small base but enlarged volume, thereby intrinsically creating an unstable container. If slot 648 is located towards upper end 642 of column 640, then ring 610 functions to hold additional containers or similarly cylindrical objects, presuming that column 640 is sufficiently sized to accept stacked containers.
  • FIGs 18-20 and 21-22 show two alternative "bail" embodiments of the invention. In both of these embodiments, support for tray 20 results from the peripheral retention of the tray by the bail members as opposed to the central retention as in previous embodiments.
  • sleeve 100 In the event that advertising on the column is desired, economies can be achieved though the use of sleeve 100, as is shown best in Fig. 23.
  • Sleeve 100 need only be sufficiently sized to fit over any column in order to function as intended. Thus, a sleeve having an internal diameter greater than either a rectilinear or curvilinear column will function with both. Additionally, if the material selection for the column yields a visually less than desirable result, sleeve 100 can be placed over it to alter its outward appearance.
  • tray 20' includes upper collar 36. Similar in function to flaps 534a-d in Fig. 14, collar 36 increases the amount of coacting surface area between the column and the tray. In addition, and unlike flaps 534a-d, collar 36 functions to reduce torque effects between a tray and a column because of its structural nature (note the incorporation of struts 37). As best shown in Fig. 26, contoured portions 25 of tray 20' closely match contoured portions 745 of column 740 from lower surface 24 to the upper periphery of collar 36. The presence of retainer 748 at this upper surface facilitates a slight compression between the column and the tray, further adding to stability of the assembly. A similar effect is found with respect to the use of column 870, however, torque transmission is reduced in view of the lack of a collar.
