(Conveyor with 4 sections)
1, 2, 6 and 8 show a four-compartment transfer device 20 used in various applications having a fixed bottom structure. The four compartments or receptacles can hold various types of other items such as beverage cups, cans or bottles and potted plants, automotive oils or fuel additives, and the like.
7-11 illustrate a preferred method of manufacturing the transport device 20, as well as other transport devices described herein. 3-5 also illustrate an upper tray accessory for transporting food or other items above the items in the 4-compartment of the transport apparatus of FIG.

The transport device 20 has a central support structure 22 consisting of two vertical support panels 23, 25 joined together by an adhesive or otherwise. The central support structure 22 has an upper edge 30 and a hand hole 28 below the upper edge 30, and the hand hole 28 has a foldable hand guard 32. At the upper part of the central support structure 22, there are a front panel 24 and a back panel 26, which are joined at the upper regions of the panels 23 and 25, respectively, to form a four-ply handle structure.
The receiving portion structure extends outward from each of the two vertical support panels 23 and 25. One receiving portion 27 is folded so as to form side walls 34, 36, and 38, and one end thereof has a panel fixed to the panel 23 by a flange 47, and the flange 47 extends from the left edge of the panel 23. 34.
Similarly, the 2nd receiving part 29 in the other side of a conveying apparatus is formed with the side walls 40, 43, 44, and has the flange 48 extended from the left edge of the panel 25 and couple | bonded with the panel 44. As shown in FIG.

  Each of the two receptacles has a bottom structure 50 or a bottom structure 52 consisting of a hinged panel 64, and the fixed panel 64 extends over the entire bottom structure (see FIG. 2) and The fixing tab 66 or the fixing tab 72 extends from the outermost end. Tabs 66 and 72 are fitted into slots 68 or 74 at the bottom of the vertical support panel 23 or 25 as shown in more detail in FIG.

Referring to FIG. 2 and FIG. 6, as with most of the embodiments of the invention described in the above-mentioned pending patent application, and like the other embodiments described herein, each receptacle is It has a bottom support structure.
FIG. 2 is a partially broken cross-sectional view taken along line 2-2 of FIG. The conveying device shown in FIG. 1 stands upright on a horizontal plane such as the surface 80 shown in FIG. The transport device 20 is folded flat when shipped, but FIG. 1 shows the transport device 20 after being expanded by the easy operation described below.
Referring to FIG. 2, the bottom structure 50 of the left-hand receiving part 27 shown in FIG. 2 shows the panel 64 immediately after the transport device is unfolded, before a beverage container or other object is yet placed on the receiving part. It is in the position before pushing the locking tab 466 downward into the slot 68.

The right receiving part 29 is shown in FIG. 2 with a cup 54 containing a drink placed. The cup containing the object pushes the panel 70 downward and pushes the fixing tab 72 into the slot 74.
The fixed or top panels 64, 70 are rectangular and are approximately the same length as the distance between the side walls 34 and 38. The rectangular panels 64 and 70 are advantageous for making the receiving portions 27 and 29 open, and the conveying device 20 stands upright with the receiving portions 27 and 29 open on a horizontal surface, so that the conveying device can be easily operated. Can be filled with beverage cups and other things.
As will be apparent from the following, when the transport device 22 is unfolded, the bottom panels 64, 70 are automatically brought into the state as shown for the panel 64 in FIG. 2 by the interlock bottom structure described below. Lowered.

Referring to FIG. 6, the bottom structure 52 comprises a wide fixed panel 70 with tabs 72 that are hinged to the bottom of the side wall panel 42. Further, the panel 88 is like a hinge from the bottom edge of the vertical support panel 23 and extends to almost half of the width of the receiving portion 29.
The first projecting structure comprises a flange that is like a hinge at the bottom edge of the side panel 44, and the flange comprises a first part 90 and a second part 91, which are separated from each other by a fold line 93. ing.
The second protrusion structure is located at the corner of the bottom structure that faces the first protrusion structure. The second protruding portion structure is like a hinge from the bottom edge of the side wall panel 40, and includes a first portion 95 and a second portion 97, and the second portion 97 is integrated with the first portion 95 at the fold line 101. It has become.
The flange portion 91 is fixed to the top panel 70, and the flange portion 97 is fixed to the panel 88.

When the transport device is unfolded, the two protruding flange structures move downward on the panels 70, 88 until both flanges reach a position somewhat above the bottom of the receiving part. The top panel 70 is pressed down by hand or by the weight of an object placed on the top panel, and the locking tab snaps into the slot, flattening the bottom structure.
The protrusion structure and the overlap of the long panels together form a strong multi-layer bottom structure that can withstand a significant amount of load.
A first partition 56 having an end tab 58 fixed to the inner peripheral surface of the wall 36 divides the left receiving portion 27 into two sections. Similarly, a second partition 62 having an end tab 62 joined to the side wall 42 is a partition for the right receiving portion 29.
Further, the gussets 51, 53, 47, 49 are provided at the joints between the side walls 38, 40, 34, 44 and the vertical panel structure. As with the partition, it is optional to provide these gussets, but the gussets make the transport device structure stronger if necessary.

(Auxiliary tray)
3-5 illustrate an auxiliary tray 92 that is designed to be used with the transport device 420. This tray is somewhat improved, but is substantially identical to the tray shown in the above-mentioned patent application.
The tray 492 has a bottom wall 104 and four upstanding side walls 94, 96, 98, 99. The side walls 494, 96 have triangular tabs 122, 134, respectively, which are adhered to the front and rear walls of the tray corners. The side walls are folded together along fold lines such as corner lines 118, 126 and fold lines 100, 120, and the trays are folded flat for transportation and storage.
As shown in FIG. 5, the bottom wall 104 has an elongated slot 112 whose central portion is wider than both ends, and two end sections 114 and 116 perpendicular to the section 112. Thus, an “I” -shaped slot is formed in the bottom wall 104.

FIG. 4 is a cutaway side view showing two beverage cups 107, 108 in the transport device 20 and a tray 490 placed on top of the cup. 4 and 5, the central support structure 22 of the transfer device extends upward through the slot 112, and the gussets 47, 49, 51, 53 extend upward through the portions of the slots 114, 116. I understand.
If a gusset is not required, the slot can be simplified to a single slot without end sections 114,116.
3 and 4 show that the height of a beverage cup or other container that will be placed on the transport device 20 varies considerably. Thus, the tops of the cups 107, 109 shown in FIG. 3 are higher than the tops of the cups 109, 110 in FIG. 4 and extend above the upper edge 106 of the side wall 42 of the transport device. However, it is preferred that the top of the beverage container is always above the top of the side wall of the transport device so that the container can be easily grasped and removed from the container, and the amount of sheet material used in the transport device is reduced. It is preferable to minimize.

(Production method)
FIG. 7 is a system diagram showing a typical process for manufacturing the transport apparatus according to the present invention.
FIG. 8 shows two blanks 136 and 138 which are folded and bonded to form a transport device as two finished products.
Referring first to FIG. 7, the fiberboard material is typically fed from the roll 128 to the print station 130 first, where the description, logo, and position are set to create a transport device in an area on the wide fiberboard material. , Advertising materials and others are printed. The sheet material is quite wide and is typically 50 inches or more, depending on the capabilities of the die-cutting, folding and printing equipment used.

The printed sheet material is then sent to a die cut and scoring machine 132 where it is cut and creased along a mold to create a blank such as blank 136,138.
As will be explained in more detail below, the array of panels formed by the multiple panels that make up the blank is linear, so several blanks can be placed side by side across the width of the sheet material, making the most of the material. The manufacturing cost of the transfer device can be minimized.
FIG. 8 shows two blanks 136, 138 that are placed side by side. Actually, three or more blanks can be stored side by side, but the third or more blanks are not shown in order to reduce the space of the drawing.
At station 132, the sheet material is cut along the mold and creased to form fold lines.
As will be described in more detail below, each blank is finally automatically glued and folded to form a fully folded transport device for packaging and transport.

(4 compartment blank structure)
Referring now to FIG. 8, in order to avoid unnecessary duplication and complexity of the drawings, the member numbers are given only to the blank 136 which is one blank.
The blanks 136, 138 and the like form a linear panel array extending in the direction indicated by the arrow 140 parallel to the longitudinal axis of the panel row.
Generally, the vertical support panel and the side wall panel are connected in series along a plurality of fold lines perpendicular to the longitudinal axis of the panel row, and the panel and the flange constituting the bottom structure of the receiving portion are connected to the axis. Are connected to the vertical support panel and the side wall panel along a plurality of fold lines parallel to each other.
As shown in the figure, the panels 23 and 24 are separated from each other except that they are connected along the fold line 144. Similarly, panels 25 and 26 are separate but connected along fold line 146.

The partition arms 56 and 60 are hinged at fold lines 147 and 149, respectively, and are formed as cutouts from the materials of the panels 23 and 25.
All the flaps or flanges constituting the bottom structure of the receiving portions 27, 29 are located along one side of the linear array. This has the advantage that when the flap and flange are folded, the automatic folding machine for the bottom need only be arranged along one side of the blank. This can reduce the number of necessary devices and / or speed up the manufacturing process.

(Folding and bonding)
9 to 11 show a folding process and an adhesion process in different stages until completion.
First, as shown in FIG. 9, an adhesive is applied to the upper surfaces of the panels 24 and 26, and the panel 24 is folded on the panel 23 along the fold line 144 and pressed to adhere to the panel 23. Similarly, the panel 26 is folded into the upper part of the panel 25 along the folding line 146 and adhered to a predetermined position.
In addition, the partition arms 56 and 60 are folded outward from the original positions, and an opening 154 or an opening 156 is formed in the panels 23 and 25.
Each panel 84, 64, 70, 88 is folded upward at the position shown in FIG.
Each flap at the corner is folded twice. That is, it is first folded along the lower edge, and then the flaps 105, 76, 91, 95 are folded downward along the diagonal fold lines of each corner structure.
Each end flange 46, 48 is folded upward, ie, the flange 46 is folded to the right and the flange 48 is folded to the left.
Next, an adhesive is applied to each flange 46, 48, 58, 105, 76, 91, 95, 62.

Next, FIG. 10 will be described. The blank is folded along the fold lines 150 and 148 shown in FIG. 9 to have the shape shown in FIG. 10, and the folded portion is pressed against the lower portion and bonded. The adhesive on the surface to which the agent is applied adheres to the contact surface. In this way, the pad 76 adheres to the flap 84, the pad 105 adheres to the flap 64, and the pad 58 adheres to the center of the panel 36.
Referring now to FIG. 11, adhesive is applied to the surfaces 23, 25 shown in FIG. 10, and the blank is folded along the center line 152 to join the two vertical support panels 23, 25 back to back. The blanks that are folded in half are pressed against each other, and a partially folded carrier blank 158 is formed.

Adopting a linear panel arrangement to form the transport device structure allows the blanks to be placed closer together and more efficiently, saving material, as well as a linear unit of sheet material However, it is also very beneficial in that more transport devices are formed, thus improving the productivity with respect to the speed of movement of the sheet material. Of course, this reduces the manufacturing costs.
The completed folded transfer device 160 shown in FIG. 11 is prepared for packing and shipping to customers. The folded transfer device 160 is advantageous in that it can save shipping containers and shipping costs because of its relatively small volume.

(Development of transfer device)
When the customer removes the box for use with the folded transport device 160, the customer simply places one hand on the rim 152 and the other hand on the blank rim 150,148 and forces in the direction of 162,164. When it is pushed together with both hands, the folded transfer device opens in the state shown in FIG.
The top tray 92 is similarly folded and shipped to the customer and opened quickly and easily for use.

(Another tray structure)
FIG. 12 shows another tray structure for mounting on the handle structure of the transport apparatus shown in FIGS.
The tray structure 166 comprises a closed type box having a side wall 168, a bottom wall 188, and a top wall 170, the top wall 170 being hinged on one side 172 of the side wall 168.
Such a box has a pair of slots 174, 176, one on the top wall 170 and one on the bottom wall 182. Each slot has a size and a shape that allow the vertical support structure 22 of the transfer device 22 shown in FIG. 1 to pass through. Each slot is covered with adhesive strips 178, 180 to protect the food in the box until the food is sold.
When the food is sold, the strips 178, 180 are peeled from the box, the vertical support panel 22 is inserted through the slot, and the food is carried with the beverage in one hand with the transport device.

Such a covered box is used to carry warm or cold pizza pie, donuts and other items, as disclosed in the above-mentioned patent application 10 / 939,264. The adhesive slot cover protects the food during storage, transport, warming and processing prior to being used to carry the food to the customer.
Box 166 is loaded with food in the processing area and sent to a remote delivery location with refrigeration if necessary. In the delivery area, the box can be heated to warm the food if necessary, the strip may be removed, and the box is placed on a transport device and delivered.
If I-shaped slots as shown in FIGS. 3 to 5 are required at the top and bottom of the box, the adhesive strip may be shaped and sized to cover each slot entirely. .

(Packed beverage transport device)
13, 14 and 15 show a packed beverage transport apparatus 190 according to the present invention. In this embodiment, the transport device 190 is a six-packing transport device and is designed to hold six bottles of soft drinks, beer, water and other beverages. This is basically the same as the transport device 22 and the other transport devices shown in the above-mentioned pending patent applications, but is specifically configured to be easily packed by an automatic filling device instead of the hand. ing. The filled conveyance device is sent to the store.
The transport device 190 shown in FIG. 13 is different from the transport device shown in FIGS. 1 to 12, and the transport device 190 does not need an auxiliary tray, so that the transport device 190 can be replaced with an existing transport device. The present invention is also different in that it is not as high as the conveying apparatus shown in FIGS. 1 to 12 because it is designed to be the same height as the existing conveying apparatus.

The transport device 190 has a vertical support structure 192 including panels 194 and 196, a front panel 198, a rear panel 200, a hand hole 202, and a folding hand guard 204 joined back to back. The upper edge of the vertical support structure is shown at 206.
Two receiving portions 220 and 222 are provided, one extending from the panel 194 and the other extending from the panel 196. The first receiving part 220 has side walls 208, 210 and 212, and the second receiving part 222 has side walls 214, 216 and 218.
The side walls are secured to the vertical support structure by flanges 270, 284 extending from the panels 194, 196.
The two partitions 258 and 264 in each receiving portion extend from the central support structure and are joined to the side wall 210 by tabs 262 and 268. Each partition has a tapered lower end 260, 266 that extends downward and extends near the bottom of the transport device, and serves as a cushion between adjacent bottles in the three compartments formed by the partitions. The possibility of cracking is reduced.

14 and 13, each of the two receiving portions 220, 222 has a bottom structure 224, 226, which is similar to one of the bottom structures shown in FIGS. However, the main difference is that the top panel 228 is hinged to the vertical support structure instead of being hinged to the opposite side wall of the vertical support structure. The top panel 228 or 232 having a bottom structure is tapered at the side edge 240 thereof.
Tapered edges 240 are provided to minimize interference between the parts of the bottom structure when the transport device is unfolded. This reduces the tendency of the top panel to keep the transport device open during filling, but the transport device is normally filled automatically by the filling device that keeps the transport device open during filling. This is not very important.
Each top panel 228,232 extends to the end of the bottom structure and has a pair of tabs 230,234. Each tab extends outwardly and protrudes from one of a pair of slots 236, 238 in the wall panels 210, 216 of the transport device to secure the top panel in place.

The bottom structure 224, 226 is in principle the same as the bottom structure of the receiving part in the conveying device 22 shown in FIGS.
Thus, when the folded transport device is brought upright by pushing opposite sides, the panels 228, 232 are not fully pushed down and remain partially upward, similar to the bottom panel 68 shown in FIG. It is in the state of.
When a full bottle of beverage is placed in one of the receptacles 220, 222, the weight of the beverage and bottle pushes the top panel downwards, the tab 230 bends and snaps into the slots 236, 238, the top of the bottom structure Fix the panel in place. This configuration, along with the other panels that support the bottom, is very lockable automatically without the need for a separately driven latch structure such as is required when manufacturing conventional transport devices. A strong bottom can be provided.

FIG. 15 shows a partially tilted bottom structure 226 for the receiving part 222 of the transport device 190 shown in FIG. Two corner structures are provided. One corner structure has a flange 248 extending from the bottom edge of the side wall 214 and the tab 250 connects to the flange 248 along the fold line 249. The tab 250 is joined to the wide top panel 232 of the bottom structure 226.
At the corner opposite the corner where the first corner flange structure is located is a second flange structure including a flange 244 that extends from the bottom edge of the side wall 218 and the tab 246 is folded. It is connected to the flange 244 along the line 251. Tab 246 is joined to flange 242 extending from the bottom edge of vertical support panel 196.
The corner flange structure operates in a manner substantially similar to the structure shown in FIGS. 1 and 6 and pulls the bottom panel downward from the folded state to open the receiver structure.

(Blank for packed beverage transport device)
FIG. 16 shows two linear arrays 288, 290, each array forming a blank for manufacturing a single transport device of the type shown in FIGS.
In FIG. 16, only two linear arrays 288, 290 are shown. These arrays are close together and minimize the amount of sheet material used. However, in a typical setting, four or more blanks fit into the sheet, indicating a material saving according to the present invention.
The manufacturing process of the transfer device 190 is substantially the same as the process shown in FIGS. The sheet material is first printed and then sent to a die-cut and scoring station where the sheet is cut and creased and creased into a shape as shown in FIG.

The various parts of the blank shown in FIG. 16 are folded and glued in almost the same way as described above, but in each receiving part, instead of only one partition, two partitions 258, 264, etc. The difference is that a partition is installed.
Panels 198 and 200 are glued onto panels 194 and 196, bottom flanges are folded and glued, end flanges 270 and 284 are similarly treated, and the blank is folded along fold lines 298 and 296, and finally The transport device folded along the center line 294 is completed and ready for use.

When folded, the transport device 190 is generally the same as the shape shown in FIG. 11, but somewhat smaller. The folded transport device occupies a smaller area than the typical prior art “sling bottom” transport device that is being replaced, so that the shipping cartons when shipped to the bottling site where the transport device is used Shipping costs can be saved.
As described with respect to the embodiment shown in FIGS. 1-11, the manufacturing process is faster and more economical with respect to material use. This can result in a significant cost reduction in product manufacture.

Is different. This allows the blanks to be brought closer together and accommodated together, and further reduces the amount of sheet material used.

(Comprehensive description-theater-specific transport device)
FIG. 23 shows a first embodiment of a theatrical transfer device 410 according to the present invention.
The transport device 410 has a vertical support structure 412. Two foldable receptacle structures 435 and 437 are fixed to the vertical support structure and extend from the vertical support structure when the transport device is opened.
One receiving part structure 435 has side walls 426, 428 and 430, and the second receiving part structure 437 has side walls 432, 434 and 436. The flaps 442 and 444 extend from the vertical support structure 412 and are bonded to the inner surfaces of the panels 430 and 432, respectively. The foldable bottom structures 460, 462 extend from the bottom wall of the receiver structure.
Partitions 446, 448 extend between side walls 428, 434 facing vertical support structure 412, and are bonded to side walls 428, 434 by tabs 448, 452, respectively. The partitions 446 and 450 are located at positions relatively close to the end portions 430 and 432, and the receiving portions 435 and 437 are relatively small. Walls 428 and 434 and bottom structures 460 and 462 extend laterally at a relatively long distance from the divider to form a third larger section or receptacle 439 on the side of each receptacle.

(Central support structure)
The central support structure 412 has a pair of relatively high vertical panels 418, 420 that are glued back to back. The four-layered handle is formed by panels 414 and 416 and is bonded to the upper part of panels 418 and 420, respectively. The handle hole 422 is provided in the vicinity of the upper edge of the structure 412 and has a foldable finger guard structure 424.
Of course, depending on the weight of the fiberboard used, the load of the object to be transported, and other conditions, an equivalent structure is produced using only two-ply or one-ply vertical support structures. Should be understood.
A large receiver 439 formed by the lateral extensions of the side walls 434, 428 and the bottom walls 460, 462 is obtained by extending the panels 418, 416 at the lower edge to form the extensions 458, 459, respectively. Strength can be increased. The extended portions 458 and 459 are bonded together to form a strong and short vertical back core at the bottom of the large receiving portion 439. The flaps 438 and 440 extending from the left edge of the panels 426 and 436 are bonded together and folded and bonded to the panel 436 as shown.

(Bottom structure)
The bottom structures 460, 462 are also shown in FIGS. 23, 24, 25 and 28.
Each bottom structure 460 or 462 has a wide top flange or panel 64 that hinges at one edge to the panel 418 or 416 and a spine formed by the panel portions 458 and 459.
As in the prior art embodiment of the transport device shown in the above-mentioned pending patent application, the panels 464, 465 preferably extend across the entire bottom of the receiving portion formed by the transport device. Each panel has three short protrusions 466, 468, 470 or 472, 474, 476 that are placed in the panel with the pressure of the hand when the panels 464, 465 are fully opened. When pushed down by the pressure of the beverage container being squeezed, it is fitted through slots 478, 480, 482 or slots 484, 486, 488.

The bottom structure 460, 462 is in the same direction as the bottom structure shown in the above-mentioned pending patent application of the same applicant and the folded end of the folded transfer device (direction indicated by arrows 461, 463 in FIG. 25). The bottom structure automatically opens when pushed to the same, and this structure is identical in that it forms a sturdy platform and supports the top panels 464, 465 and the receiving article.
As shown in FIGS. 424 and 425, the front corner of the receiving portion 435 has a flange or flap 490 having a tab 494, which is secured to the long flange 506 and has an oblique fold line 495. ing. Similarly, a flap 498 having a tab 502 extends from the rear wall 426 behind the transport device, and the tab 502 adheres to the back surface of the panel 464. The flap 498 is folded along an oblique line 499.
Similarly, the bottom structure 462 has a flap or flange 492 attached like a hinge to the bottom edge of the panel 432. The flange 492 has a tab 496 that is bonded to the flange 508. The flange 492 has an oblique fold line represented by 497.
Then, behind the structure 462, a flange 500 with a tab 504 is attached to the wall 432 like a hinge. Tab 504 is bonded to panel 465 and has an oblique fold line 501.

Referring again to FIG. 23 and FIG. 28, the panels 464, 465 are basically rectangular. The rectangular shape has the following advantages, that is, when the flanges 464 and 465 are pulled downward by the corner tab, the flange has a space between the front wall and the rear wall of the receiving portions 435 and 437. A force is applied to the end of the transport device that is created and folded so that once the transport device is unfolded, it is placed on the counter so that articles to be transported by the transporter can be quickly packed into the transport device. Meanwhile, the transfer device is kept open.
When the conveying device is folded flat, the rear corners of the panels 464 and 465 are folded downward along the folding lines 467 and 469 to engage with the panels 426 and 436, respectively. When the conveying device is spread and the panels 464 and 465 are pushed downward, the corners of the panel push the panels 426 and 436, and when the tabs along the edges of the panels 464 and 465 are fitted into the slots, the conveying device is fully opened. It is. Conveniently, the tab can be easily fitted into the slot by placing the beverage in the beverage receiving portion, and the weight of the beverage pushes the panel down and seats the panel appropriately.
It should be noted that the bottom edges 454, 456 of the partitions 446, 450 are cut upward as shown to prevent the panels 464, 465 and the partitions from interfering when the transport device is unfolded. It is.

(Food delivery)
FIG. 26 shows the usage state of the transport device 410 in a typical food delivery process.
For example, consider when the transport device 410 is used in a movie theater where beverages in cups 514, “buckets” 510 with popcorn and boxed or bagged candy bars are sold.
First, the blank end of the transport device is unfolded by pushing the blank end in directions 461, 463 (FIG. 25), the beverage 514 is placed on the receiving portions 435, 437, and the bucket 110 of the popcorn 112 is a large container as shown in FIG. 439 and the bottom of the bucket rests on the vertical spine 458,459. Popcorn is very lightweight, balanced by the weight of the beverage 514, and can easily carry popcorn and beverages with the handle 422 with one hand.
If the customer purchases a solid food product such as a candy bag, a candy box or candy bar, a hot dog, these items are placed on a tray 516, which is inserted into the top of the vertical support structure 412. It is. Thus, customers can carry drinks, large containers with popcorn, candy on a tray, etc. with one hand. Most of the weight is concentrated at the bottom of the handle.
If the bucket 510 contains relatively heavy items such as fried chicken, fried shrimp, etc. instead of the lightweight popcorn shown at 512, the other hand can support the left side of the transport device. desirable.

FIG. 27 is a plan view of the tray 516 and is shown in more detail in some of the above-mentioned pending patent applications. The tray 516 has a bottom wall 520 with an extended slot 522, and the vertical support structure 12 penetrates through the slot 522. The tray has four side walls 524, 526, 528, 530 that are angled upward as shown in the figure and bonded to each other at the corners.
If desired, as described in pending patent application 10 / 939,264 filed on Sep. 10, 2004, instead of the open tray 516, and further described below. A closed type food box can be used. Closed-type containers can contain donuts, bagels, pizzas, and other foods that can be heated in the box before the box is attached to the transport device.
Beverage cups smaller than those described above will not fill the receptacles 435,437. For this reason, and for other reasons, it is desirable to provide means for stably holding the beverage cup so that it does not tilt or slip sideways.

This can be achieved by another aspect of the invention, i.e. adding flaps 554, 556 as indicated by the dashed lines in Fig. 28, and these flaps are folded into the beverage receiver compartment from above to provide holes 558, 560 respectively. It can be configured and stably held so as to surround a substantially semi-cylindrical beverage cup.
This aspect is shown schematically in FIG. 23, where the beverage retaining hole 560 is shown in broken lines. The size of the flap panels 554 and 556 is preferably such that the flap fits in the upper edge of the side wall of the receiving portion.

(Blank for transport device creation)
FIG. 28 shows a blank of the transport device 410. The blank is preferably made of a single sheet of fiberboard material. The folding line is indicated by “F”, and the region to which the adhesive is applied is indicated by “G”.
The conveying device is manufactured by a process of die-cutting a single sheet material, followed by folding and attaching an adhesive.
A relatively large number of transfer devices are manufactured at a relatively appropriate price.

(Preferred embodiment)
29-31 show a preferred transport device 531 according to the present invention. The transport device 531 is substantially the same as the transport device shown in FIGS. 23 to 28 except for certain changes. Accordingly, the members of the transport device 531 corresponding to the members of the transport device 410 shown in FIGS.
One of the differences between the conveying device 531 shown in FIGS. 29 to 31 and the conveying device shown in FIGS. 23 to 28 is that the rear portions of the vertical side walls 426, 428, 434, and 436 correspond to the above-described conveying device. It is considerably higher than the side wall. Bent cuts 548 and 550 are provided in such a high side wall so that the height is lowered in front of the transfer device so that access to the receiving portions 435 and 437 is facilitated.

Another difference in the conveying device 131 is that two folding seal panels 536 and 538 are provided, which seal the large receiving portion 439 from the smaller receiving portions 435 and 437 and remove the bucket. It allows popcorn, fried chicken or other items to be transported in a large receptacle 439 without using them, so that they are not in the small receptacle.
Each panel 536, 538 is like a hinge along fold lines 534, 532, and is folded to a lower position in the direction indicated by arrows 544, 546. In FIG. The space is closed under the lower edges 454, 456 to form a vertical wall that seals the large receptacle from the small receptacle.

In addition, tabs 540 and 542 (FIG. 30) are provided on the edges of the panels 536 and 538, and are fitted into slots provided at appropriate locations in the bottom structure of the transfer device to fix the security panels 536 and 538 in place. You can also In addition, the fixing function may simply ensure engagement by friction between the lower edge of each panel 536, 538 and the corresponding portion where the lower edge of the panel of the bottom structure of the receiving portion comes.
When the transport device 531 is unfolded, the panels 536 and 538 are bent downward after the folded end of the transport device is pushed toward the corresponding end. This has the advantage of pressing the top panels of the bottom structure downwards and fixing them in place.
With this modification, other foods in small chunks such as popcorn, fried chicken or French fries etc. can be used to hold directly by the large receptacle 439 without using a “bucket”.

FIG. 31 shows a transport device blank that is substantially the same as the transport device shown in FIGS. 29 and 30 except that the transport device is sized to carry only two beverage cups at the receiving portions 435 and 437. Show. In other words, the blank shown in FIG. 31 can be said to be somewhat longer than the 4-cup transport device.
Similarly, the fold line is indicated by “F” and the region to which the adhesive is applied is indicated by “I”. Further, the cutting line is marked with “C”.
One of the differences between the blank shown in FIG. 31 and the transport device shown in FIGS. 23-28 is that the flaps 442, 444 used to secure the side walls to the vertical support panel are Instead of extending from the left end, it extends from the right end of the panels 430 and 432.
Further, if necessary, one of the flaps 438 and 440 may be omitted, and it is understood that the joint portion on the rear wall of the transfer device is formed by bonding one flap to the vertical side wall. It should be.
It can be seen that the security panels 536 and 538 are made of the material forming the third and fourth sheets of the handle structure shown in FIG. Therefore, the handle structure of the embodiment shown in FIGS. 29 to 31 is not a four-ply but a simple ply. However, this is not a substantial drawback.
FIG. 31 shows the main reason why the heights of the walls 426, 428, and 434 are increased. The heights of the walls 426, 428, and 434 extend to the same place so that the side wall material extends to the cutting line “C” in the center of FIG. Thereby, the automatic manufacturing speed of the conveyance apparatus by the latest manufacturing apparatus can be further increased.

(material)
The material from which the transport device of the present invention is manufactured need not be expensive. Normally, medium weight fiberboard seems to be sufficient for most applications. For example, 0.20S. U. S. Can be used. If water resistance beyond the acrylic coating is required, a further waterproof coating can be applied to both the inner and outer surfaces.
It is also within the scope of the present invention to manufacture the transport device from an elastic plastic material.
If desired, the transport device can be manufactured from a readily washable plastic material so that it can be reused.

(Joining)
The members can be joined together with a material other than the adhesive. For example, in the case of a plastic member or a member coated with plastic, bonding by ultrasonic waves or heating is also possible. Staples or other mechanical fasteners can also be used.
From the above, it can be seen that the present invention sufficiently fulfills the above-mentioned object. Conveyor structure that allows blanks to be manufactured from a linear array allows multiple blanks to be more efficiently accommodated on a sheet of fiberboard material, thereby further saving material used in the conveyor .
Furthermore, the automatic manufacturing speed of the transfer device can be increased, and the manufacturing cost is reduced accordingly. Furthermore, the complexity of certain folding machines can be eliminated.
The above description of the present invention is intended to be apparent by way of example and not limitation. Various changes and modifications in the above-described embodiments may be made by those skilled in the art. These can be made without departing from the essence and scope of the present invention.
