Double panel boxes

Abstract

A box includes a plurality of outer panels collectively bounding an accommodation space for accommodating at least one item. At least some of the outer panels have integrally formed inner panels and distancing flaps for holding the item accommodated at a distance from the respective outer panel. The inner panels are distanced from their respective outer panels by folding an associated closing panel or distancing flap with respect to the outer panel.

Description

BACKGROUND OF THE INVENTION

The present invention relates to packaging in general, and more particularly to packaging boxes for accommodating various items or goods, especially during transportation and/or for display.

Various packaging boxes and shipping containers are known, among them ones that are especially equipped in one way or another for the shipping of items or goods in a protective manner. For instance, sensitive items such as electronic equipment are oftentimes shipped in regular parallelepiped corrugated cardboard boxes, but, in order to protect the items from potentially damaging shocks and vibrations while in transit, the items are often supported on blocks or specially molded formations of foamed polyurethane that hold the items at a distance from the panels forming the box and suppress the transmission to the items of any impacts, shocks, vibrations and/or other forces to which the box itself may be subjected.

Protecting items in this manner contributes to the cost of the packaging material and operation and thus to the cost of the item. Various other techniques have been proposed to achieve similar protection in a less expensive way, such as using box-shaped cardboard inserts to keep the item at a distance from the box panels, foamed polyurethane pellets or beads, or the so-called bubble-wrap sheets. All of these approaches, however, have certain drawbacks, be it their cost or the inadequacy of their supporting or cushioning action, or the failure by packing personnel to find or use the appropriate protective materials.

SUMMARY OF THE INVENTION

Accordingly, it is a general object of the present invention to avoid the disadvantages of the prior art.

An object of the present invention is to provide a double panel box which has the double panel construction as an integral part of the box. For example, embodiments according to the invention have the advantage of providing a double panel construction that is a permanent part of the box for as long as the box is being used.

Another object of the present invention is to construct the double panel box to be relatively simple in construction, inexpensive to manufacture, easy to use, and yet reliable in operation. For example, embodiments according to the invention do not require any special handling in order to put the double panel features into effect.

Thus, in accordance with embodiments of the invention, a box is provided with one or more inner panels, each being distanced, by at least one distancing flap, from a respective outer panel in a direction toward the accommodation space of the box. This thus forms a double panel construction.

The double panel construction provides a protective cushioning effect, keeping the items in the box distanced from the outer panels. The double panel provides a buffer for absorbing shock and/or vibration.

The double panel construction also has additional uses such as for facilitating display of the goods. For example, a cutout may be provided in an inner panel to support goods on display.

A particular advantage of the double panel arrangement according to embodiments of the invention is that the inner panel and distancing flap arrangement, by virtue of being integral parts of the box, cannot be either lost or misplaced, or inserted into the accommodation space in an improper orientation.

Another particular advantage of the double panel arrangement according to embodiments of the invention is that a box having the double panel construction may be constructed from a single flat sheet of material, properly cut, folded, and fastened (e.g., glued or stapled) in accordance with the invention. In addition, once the box is cut, folded, and fastened, it can be folded in a manner such that it can lie substantially flat, can be readily erected in a simple manner, and can be repeatably and easily collapsed flat and erected. That is, for example, after the box is cut, folded, and fastened, with the closing panels in a open position, the distancing flaps can be oriented parallel to their adjacent outer panels, such that the distancing flaps and corresponding inner panels lie flat against their adjacent outer panels. In this manner, the box can be collapsed flat without the need for any ungluing or unstapling. When the box is erected, the distancing flaps can be moved to a position in which they are then substantially perpendicular to their adjacent outer panels and the respective inner panels correspondingly can be moved toward the center of the box to a distanced position in which they are then displaced from their respective adjacent outer panels. In this manner, the box is fully erected. The process can be reversed and repeated, allowing the box to be repeatedly collapsed flat and erected, without the need for any ungluing or unstapling or additional gluing or stapling.

In an embodiment of the invention, inner panels and distancing flaps may be provided, for example, integrally with at least first and second outer side panels that face one another across the accommodation space. Inner panels and distancing flaps may also be provided integrally with third and fourth outer side panels that also face one another across the accommodation space, the first through fourth outer side panels forming a square or rectangular perimeter around the accommodation space. In this embodiment, each of the sides of the box has a double panel construction.

When the box comprises first through fourth outer side panels as described above, the top and bottom open ends may each be provided with at least one closing panel for closing, in whole or in part, at least one of the open ends. In this situation, one or more additional inner panels and distancing flaps, similar to those previously described, may be provided on one or more of the closing panels. Each of the top and bottom open ends may have a pair of closing panels, one of which is integral with one of the outer side panels of the unit and the other with that of the outer side panel of the unit that faces the same, the paired sections complementing each other when in their closed positions with the box being in its erected condition. Inner panels and distancing flaps may be associated with each closing panel.

In another embodiment, there may be provided two pairs of partitioning flaps, each partitioning flap integral with one of the closing panels and forming an extension thereof. One pair of partitioning flaps adjoins the corresponding region of the other pair of partitioning flaps when the closing panels are in their closed positions. The partitioning flaps may have respective slots so that the slots of each of the pairs of partitioning flaps receive associated solid portions of the partitioning flaps of the other pair when said partitioning flaps extend into and across the accommodation space in a closed condition of the box to partition the accommodation space into a plurality of compartments.

A double panel construction may be provided on the top or bottom of the box with or without having a double panel construction on one or more of the sides of the box. In one example, two closing panels on the top of the box are each provided with an associated inner panel and distancing flap. In another example, one closing panel on the bottom of the box is provided with an associated inner panel and distancing flap. Such a construction may be useful for cushioning food items such as cereals or cookies. In another example, one closing panel on the top of the box and one closing panel on the bottom of the box are each provided with an associated inner panel and distancing flap. Many other variations are conceivable within the scope of the invention.

In another application of a double panel construction in accordance with an embodiment of the invention, a double panel box may be provided in the form of an open-end double panel box cap. For shipping large items, for example, a tall box sleeve with open ends is provided, the ends being closable by box caps. In accordance with embodiments of the present invention, the side panels and/or the end closing panels of the box cap may each be provided with an associated inner panel and distancing flap. In this manner integral cushioning is provided at the ends of the assembled package, and in some applications additional inserts are unnecessary.

An inner panel in accordance with the invention may be parallel to the outer panel with which it is associated, or it may be at an angle therewith. The inner panel may have one section, or it may have one or more bend lines separating it into more than one inner panel section.

In accordance with further embodiments of the invention, one or more cutouts may be provided in the inner panel. The material at the cutout may be folded to provide a buttress flap and a buttress connecting flap for providing further support for the inner panel. The material at the cutout may additionally or alternatively be used as supporting flaps for supporting the goods to be shipped. Such a construction is useful for shipping items of a particular shape, for example circuit boards. Alternatively, the material at the cutout may be taken away in its entirety, such that the cutout area itself, as bounded by the remainder of the inner panel, provides support for the goods to be shipped.

In many of the embodiments according to the invention, the inner panel and/or the distancing flap is connected to an outer closing panel such that the inner panel is moved to its distanced position in which it is displaced from an adjacent outer panel when the closing panel is closed.

In other embodiments, an inner side panel may be provided with two distancing flaps that connect that inner side panel to an outer side panel, so that the inner side panel is moved to its distanced position when one or more of the distancing flaps is folded relative to the outer panel. As with other arrangements, more than one such inner panel may be provided in accordance with this arrangement.

The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

Reference is now made to the drawings in detail, in which the same reference numerals are being used therein as well as throughout this description to identify the same or similar but corresponding parts. Thus, for instance, the reference numeral 10 is used in the various figures for identifying a box incorporating a double panel feature of the present invention, in its entirety, regardless of the structural details of such a box 10.

FIGS. 1 to 6 show a box 10 of the present invention including, like many conventional boxes do, a plurality of outer side panels 11 to 14, including a front side panel 11, a back side panel 13, two side panels 12 and 14 interconnecting the front and back side panels 11 and 13, and respective top and bottom outer closing panels 31 to 34. The outer closing panels 31 to 34 span the spaces between the outer side panels 11 to 14 in a closed condition of the box illustrated, for instance, in FIG. 2. In the illustrated example of the box 10, the outer closing panels are constituted by a pair of top outer closing panels 31 and 32 and a pair of bottom outer closing panels 33 and 34, respectively. It may also be noted that there is further provided a connecting flap 19 that is integral with the outer side panel 13. In the assembled condition of the box 10, the connecting flap 19 overlaps and is joined (for instance glued or stapled) to the outer side panel 14.

The double panel box 10 of FIGS. 1 to 5 is further provided with respective inner side panels 15 to 18 that correspond to the outer side panels 11 to 14, respectively, in that order. The inner side panels 15 to 18 are joined to the outer side panels 15 to 18 in a manner yet to be described, and are spaced from them in the erected condition of the box 10. The doubling of at least the side panels by providing the inner side panels 15 to 18 in addition to the outer side panels 11 to 14 and causing them to be spaced from the latter in the erected condition of the box 10 provides additional protection for the goods to be transported in the box 10.

The inner side panels 15 to 18 are, in the erected condition of the box, spaced from the associated outer side panels 11 to 14 by distancing flaps and/or connecting flaps 21 to 28. The distancing flaps and connecting flaps, like the outer and inner side panels 11 to 18 and outer closing panels 31 to 34, are integral parts of a single preform made of corrugated board or any other conventional box-forming material. The preform for the box of FIGS. 1 to 5 is shown in FIG. 6. It will be appreciated that, in the erected condition of the cushioning box 10, all of such distancing and connecting flaps 21 to 28 are permanently joined to the adjacent and associated ones of the panels 11 to 18 and/or 31 to 34, either by being integral therewith as the side distancing flaps 21, 23, 26 and 28 are bilaterally, and the connecting flaps 22, 24, 25 and 27 are on one side, or by being glued, stapled or otherwise attached thereto as the connecting flaps 22, 24, 25 and 27 may be to the closing panels 31 to 34, respectively. On the other hand, in some instances it is not necessary to so permanently connect some of the flaps 22, 24, 25 or 27. It will also be appreciated that any and all of the connecting flaps 22, 24, 25 or 27 may be folded in a direction opposite to that illustrated so as to have their ends braced against the associated side panels 12, 14, 11, 13, respectively.

The distancing and connecting flaps 21 to 28 keep the inner side panels 15 to 18 at a distance from their associated outer side panel counterparts 11 to 14 in the illustrated erected condition of the box 10. As a result of this, the goods or items in the box 10 may be braced against the inner side panels 15 to 18 without any additional protective or cushioning measures having to be taken, and yet be fully protected not only from the effects of vibrations and minor shocks to which the box 10 may be subjected as it is being handled during transportation from one location to another, for instance, but also from relatively large shocks and impacts and even from concentrated impacts that may penetrate and damage one or more of the outer panels 11 to 14 but stop short of reaching or piercing the associated inner panel 15 to 18.

These advantages are also obtained in the box 10 that is illustrated in FIGS. 7 to 10. This box is similar to that illustrated in FIGS. 1 to 5, except that in addition to the double panel structure constituted by the full panels 11 to 18, the half-panels 31 to 34, and the distancing and connecting flaps 21 to 28, the box structure of FIGS. 7 to 10 also includes a partitioning or compartmentalization feature. In particular, partitioning flaps 41 to 44 are provided that adjoin and are of one piece with the top and bottom closing panels. The partitioning flaps 41 to 44 are preferably dimensioned to span substantially the entire distance between the top and bottom closing panels 31 to 34 in the fully closed condition of the box 10 that is shown in FIGS. 8 to 10 of the drawing, and are provided with respective accommodating slots 51 to 54. The slots 51 to 54 extend over substantially one half of the width of the associated partitioning flap 41 to 44, but a different length distribution among the slots 51 to 54 is conceivable and may even be preferred in certain circumstances.

In a closed condition of the box 10, the partitioning flaps 41 to 44 are interlocked and thus held in position without freedom of movement in any direction other than the box-opening one, and even that one only when accompanied by deformation of the flexible material of the flaps 41 to 44, in that respective portions of the flaps 41 to 44 are received and confined in the associated ones of the accommodation slots 53, 54 or 51, 52. It may be seen that the partitioning walls 41 to 44 subdivide the interior of the box 10 into respective separate compartments each for accommodating one or more of the goods or items to be transported, stored, put on display or otherwise handled while in the box 10, with such separately accommodated goods or items being prevented by the partitioning flaps 41 to 44 from bumping against or otherwise coming in contact with the goods or items contained in the other such compartments.

If desired, the positional stability of the partitioning flaps 41 and 42 (and, similarly, of the flaps 43 and 44 as well) may be increased by anchoring their respective outer margins in the closed condition of the box 10 to the double panels 11, 15 and 13, 17 (or, in the case of the partitioning flaps 43 and 44, to the double panels 12, 16 and 14, 18). To this end, respective cutouts 55a and 55b (and/or similar non-illustrated additional cutouts) are provided in the distancing flaps 21 and 23 (and/or 26 and 28, if necessary) and the inner panels 15 and 17 (and/or 16 and 18) for receiving the corresponding portions of the partitioning flaps 41 and 42 (or 43 and 44).

Moreover, to further increase the security of such anchoring, the partitioning flaps 41 and 42 are shown to be provided with respective auxiliary accommodation slots 56a, 56b and 57a, 57b, respectively, that flank the slots 51 and 52 and, in the closed condition of the box 10, receive corresponding portions of the inner panels 15 and 17, respectively. A similar additional anchoring feature could also be implemented with respect to the partitioning flaps 43 and 44 and the associated inner panels 16 and 18, but this, like the aforementioned primary anchoring feature, has not been illustrated because it ought to be clear without specific illustration.

FIGS. 11 to 15 of the drawings illustrate, in addition to features shown in and described above in conjunction with FIGS. 1 to 6, an additional double panel feature in accordance with the present invention. More particularly, while the goods are well protected from all sides in the box constructions illustrated in FIGS. 1 to 10, they may still be vulnerable to some extent to external influences or forces directed against the top or bottom panels of the box 10. In the box structure illustrated in FIGS. 11 to 15, additional protection is provided in the same, relatively simple manner by giving the top and bottom walls of the box 10 a double panel construction. In this case, as shown in FIGS. 11 and 13 to 15, inner panels in the form of closing panel inner panels 45 to 48 are being used for doubling the respective top and bottom panels of the box 10. To this end, the closing panel inner panels 45 to 48 are connected to and separated from the associated ones of the top and bottom outer closing panels 31 to 34 by respective distancing flaps in the form of closing panel distancing flaps 61, 62, 65 and 66 integral therewith, and are provided with respective connecting flaps 63, 64, 67 and 68. Without further detailed discussion, it should be clear at this point that the distancing flaps 61, 62, 65 and 66 perform the same function with respect to the outer panels 31 to 34 and inner panels 45 to 48 as their counterparts 21, 23, 26 and 28 do with respect to the inner and outer panels 11 to 14 and 15 to 18.

FIGS. 16 to 18 illustrate a box 10 that is particularly suited for use in displaying goods or items, preferably those that have been transported to a retail establishment in the box 10. In this construction of the box, only three side walls of the box 10 (or the side and bottom walls of the box 10 as considered in its display position) are shown to be doubled. Instead of being used for either partitioning or for wall doubling, the flaps 43 and 44 are being used in this instance as spacers or back supports for the items on display (not shown).

As also shown, the back wall may have two adjacent panels for the purposes of stability. Thus, an additional full panel 35 is glued or otherwise permanently secured to the outer closing panels 33 and 34 at their back, as considered in the illustrated position. Furthermore, the partial panel 32 (or, in its absence, as shown, the reinforcing member or panel 35 which in this instance is extended forward and then upward) may have secured thereto another panel 36 that may carry advertising or other matter and may be positioned in the manner shown in FIGS. 16 and 17 so as not to interfere with free access to the goods on display.

On the other hand, the outer closing panel 31 may be folded, either on itself or, as shown, around a reinforcing strip 37, to also be out of the way as far as access to the goods is concerned, while still providing a rim or barrier that prevents the bottommost goods on display from accidentally sliding or inadvertently being pulled out of the confines of the box 10 in which they are being presented to view. FIGS. 16 to 18 also reveal that cutouts 58 and 59 may be provided at substantially corresponding locations of the inner panels 15 and 17 to facilitate the handling of the box 10 at the display location and/or to provide additional support for the goods on display.

Many variations within the scope of the invention are conceivable. For example, FIGS. 19 and 20 show an alternate embodiment of the box 10 in which only the top of the box has the double panel feature. The two outer closing panels 31 and 32 are each provided with associated closing panel inner panels 45 and 46, respectively. Distancing flap 61 is connected to outer closing panel 31 and to closing panel inner panel 45, and distancing flap 62 is connected to outer closing panel 32 and to closing panel inner panel 46. The closing panel inner panels 45, 46 are connected to adjacent outer side panels 12, 14 by connecting flaps 63, 64, respectively. The double panel construction operates in a similar manner to that previously described in that when the outer closing panels 31, 32 are folded to the closed position, the inner panels 45, 46 are moved toward the center of the box to a distanced position in which they are displaced from the adjacent outer closing panels 31, 32. It should be noted that a further outer panel 72 is provided in the illustrated box, with a locking tab 70, for further closing off the top of the box.

FIGS. 21 and 22 show an alternate embodiment of the box 10 in which only the bottom of the box has the double panel feature. In this case, outer closing panel 33 itself substantially extends across the bottom of the box and is alone provided with an associated closing panel inner panel 47. Distancing flap 65 is connected to the outer closing panel 33 and to the closing panel inner panel 47. The closing panel inner panel 47 is connected to the adjacent outer side panel 11 by connecting flap 67, which is, for example, glued to outer side panel 11. (The glue area is shown by a dark strip in the preform view in FIG. 24.) Again, this double panel construction operates in a similar manner to that previously described in that when the outer closing panel 33 is folded to the closed position, the inner panel 47 is moved toward the center of the box to a distanced position in which it is displaced from the adjacent outer closing panel 33. This embodiment may be useful for cushioning food items such as cereals or cookies. It should be noted that the illustrated box has closing flaps 75 to 78. The closing flaps 77, 78 as well as outer closing panel 34, which has a locking tab 70 for inserting into slot 79, are provided for further closing off the bottom of the box.

FIG. 23 shows a box similar to that shown in FIG. 22, except that it has not only a double panel on the bottom of the box but also a double panel on the top of the box. The double panel at the bottom of the box is the same as in FIG. 22. At the top of the box, closing panel 31 is provided with an associated closing panel inner panel 45. Distancing flap 61 is connected to the outer closing panel 31 and to the closing panel inner panel 45. The closing panel inner panel 45 is connected to the adjacent outer side panel 11 by connecting flap 63. Again, this construction operates in a similar manner to that previously described in that when the outer closing panel 31 is folded to the closed position, the inner panel 45 is moved toward the center of the box to a distanced position in which it is displaced from the adjacent outer closing panel 31.

FIG. 24 shows a preform from which the packaging box of FIG. 21 can be formed by folding and connecting the respective associated portions. As shown, the box can be constructed from a single flat sheet. The portions 33, 65, 47, and 67 are folded with respect to each other to form the double wall construction, with the connecting flap being glued, for example, to side panel 11. FIG. 24 also shows an example of the type of conventional flaps 31, 32, 75, 76 that can be used to close the top of the box.

FIG. 25 shows a packaging arrangement incorporating two boxes in the form of box caps 10 according to another embodiment of the present invention. Such a packaging arrangement may be used, for example, in packaging for shipping large items. A tall box sleeve 80 with open ends is provided, the ends being closable by the box caps 10 as shown. The outer side panels 11 to 14 of the box caps 10 fit within the sleeve 80, with the box cap flaps 81 to 84 abutting against the end of the sleeve 80.

FIGS. 26 to 28 show details of a box cap according to an embodiment of the invention. The box cap 10 has outer side panels 11 to 14 provided with associated inner side panels 15 to 18, respectively. The inner side panels are connected to and distanced from the respective outer side panels by distancing flaps 21, 26, 23 and 28. Connecting flaps 25, 22, 27 and 24 are provided for connecting the inner side panels 15, 16, 17 and 18 to outer end closing panels 31, 33, 32 and 34, respectively. The connecting flaps 25, 22, 27, and 24 are attached, for example by gluing, to the respective outer end closing panels 31, 33, 32 and 34.

The double panel construction in the box cap 10 operates in a similar manner to that previously described. When the end closing panels 31, 33, 32 and 34 are folded to the closed position, the respective inner panels 15, 16, 17 and 18 are moved toward the center of the box to a distanced position in which they are displaced from the adjacent outer side panel 11, 12, 13 and 14, respectively. It should be noted that the flaps 81 to 84 are formed from cutouts in the outer side panels 11 to 14, respectively, and are integral with the end closing panels 31, 33, 32, and 34, respectively, such that the end closing panels 31, 33, 32, and 34 can be moved to a closed position simultaneously with the movement of the flaps 81 to 84 away from and perpendicular to their respective side panels 11 to 14. The arrangement of the various parts of this box cap is shown in the preform view of FIG. 29.

FIGS. 30 to 32 show an alternate embodiment of a box cap 10 according to the invention. This embodiment is similar to that previously described, except that it has an additional double end panel construction. Thus, closing panel inner panels 47 and 48 are associated with outer closing panels 33 and 34, respectively. Distancing flaps 65 and 66 connect the closing panel inner panels 47 and 48, respectively, with the associated outer closing panels 33 and 34, and connecting flaps 67 and 68 connect the closing panel inner panels 47 and 48, respectively, with the adjacent inner side panels 16 and 18. These inner panels 47 and 48 are moved into their distanced positions by the closing of the outer closing panels 33 and 34 in a manner similar to that already described. A preform for constructing a box cap according to FIGS. 30 to 32 is shown in FIG. 33.

It should be appreciated that an inner panel in accordance with the invention may be parallel to its associated outer panel, as shown in the embodiments illustrated in FIGS. 1 to 33, but it need not be. The inner panel may alternatively be in a plane that lies at an angle with respect to its associated outer panel. The inner panel may additionally or alternatively have one or more bend lines separating it into more than one section.

Accordingly, FIGS. 34 and 35 illustrate an embodiment in which the inner panels 16, 18 are at angles with respect to their associated outer panels 12, 14. Each of the inner panels 16, 18 has a bend line separating it into two sections, 16a and 16b, and 18a and 18b. The operation of this embodiment is similar to that previously described. It should be noted that the illustrated box has additional outer closing panels 73 and 74, which can be seen in the preform view illustrated in FIG. 36.

In accordance with further modifications possible within the scope of the invention, one or more cutouts may be provided in the inner panel(s) and/or distancing flap(s). The embodiment shown in FIGS. 37 to 40 corresponds in many respects to that shown in FIGS. 1 to 5. In this embodiment, however, cutouts 85 to 88 are provided in each of the inner side panels 15 to 18, and the material at each cutout is folded to provide a buttress flap 91 to 94 and buttress connecting flap 95 to 98 for providing further support for the inner panel. The buttress connecting flaps 95 to 98 are attached, for example by gluing, to the outer side panels 11 to 14, respectively. It will be appreciated that the buttress flaps 91 to 94 move in a manner similarly to the distancing flaps 21, 26, 23, and 28 when the outer closing panels 33, 31, 34, and 32 are moved into and between their open and closed positions. A preform for the box of FIGS. 37 to 40 is shown in FIG. 41.

Cutouts may be utilized for other purposes. For example, as shown in the embodiment of FIGS. 42 and 43 (with a preform for this embodiment shown in FIG. 44), the material at the cutouts may be used as supporting flaps 102, 104, 106, 108 for supporting the goods to be shipped. This feature may be combined with other features previously described, for example, with an inner panel that is separated by one or more bend lines into a plurality of panels, as shown in the embodiment of FIGS. 45 and 46 (with the preform shown in FIG. 47). Such an embodiment may be used for particular items, such as electronic circuit boards.

In other embodiments, such as that shown in FIGS. 48 and 49, the material at the cutouts 89, 90 may be taken away in its entirety, such that the cutout area itself, as bounded by the remainder of the inner panels 16, 18, provides support for the goods to be shipped. Such a construction may be useful for shipping items such as glass stemware or automobile headlights, for example. For multiple items, more than one cutout may be used. The preform view for the FIG. 48 embodiment is shown in FIG. 50.

In the embodiments described thus far, the inner panel and/or the distancing flap is connected to an outer closing panel such that the inner panel is moved to its distanced position in which it is displaced from an adjacent outer panel when the closing panel is closed. In other embodiments, an inner side panel may be provided with two distancing flaps that connect that inner side panel to an outer side panel. In such a case, the inner side panel is moved to its distanced position when one or more of the distancing flaps is folded relative to the outer panel.

Such an embodiment is illustrated in FIGS. 51 to 53. Inner side panels 122, 128, 142, and 148 are provided in the illustrated embodiment. Inner side panel 122 has two associated distancing flaps 121, 123 that distance it from the associated outer side panel 12. Two connecting flaps 124, 125 connect the distancing flap 123 to the outer side panel 12. Inner side panel 128 similarly has two distancing flaps 127, 129 that distance it from the associated outer side panel 12. One connecting flap 126 connects the distancing flap 127 to the outer side panel 12. Inner side panel 142 with its associated distancing flaps 141, 143 and connecting flaps 144, 145 is similar in construction to inner side panel 122. Inner side panel 148 with its associated distancing flaps 147, 149 and connecting flap 146 is similar in construction to inner side panel 128. It will be appreciated that by folding the associated distancing flaps, each inner side panel in this embodiment may be alternately moved between a position in which lies flat against its associated outer side panel, with its respective distancing flaps substantially parallel to the outer side panel, and a distanced position in which it is displaced from its associated outer side panel, with its respective distancing flaps folded to be substantially perpendicular to the outer side panel.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above.

While the present invention has been described and illustrated herein as embodied in certain specific constructions of a box, it is not limited to the details of these particular constructions, since various modifications and structural changes may be made without departing from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
