ct e The following statement is a full description of this invention including the best method of performing it known to us:o c I C, CONTAINER WITHE LONGITUDINAL PASSAGE WAYS BACKGROUM TD OF THE INVENTION This invention relates to containers typically used for grapes, other types of produce or products which require ventilation or cooling.

Certain types of products, such as grapes, other type s of produce or flowers, require cooling or ventilation prior to shipping or during shipping of the product For example, grapes-may be harvested at relatively high temperatures of 20 -30 'Celsius; However they would suffer considerable loss of quality or deterioration if shipped at that temperature.

Consequently, the grapes may be cooled prior to shipment or during shipment to maintain the grapes in good condition until they reach the consumer.

For example, grapes are frequently shipped in containers typically made of plastic, wood or corrugated paperboard. The latter material is highly desirable from the point of view of recycling the containers. When the grapes reach the destination point, corrugated containers can be flattened and sent back to a recycling depot for repulping. However, in the past, :corrugated paperboard containers have permitted less than optimal cooling rates. This may 2 cause a significant bottleneck at the vineyards or packing houses where the grapes must be cooled after harvesting before shipment For example, one method of cooling the grapes is to stack the containers adjacent each other In a room. Cooling air is forced through the stack of containers containing grapes by large cooling fans. The stacked containers must remain in place until the grapes are cooled to a particular temperature. Grapes often are harvested rapidly when conditions are right.

However additional containers of grapes cannot be cooled or subsequently shipped until the containers contain ing grapes already in the cooling room reach the desired temperature.

-2- It has been recognized in the prior art that the cooling of grapes or other products can be facilitated by placing openings in the containers so as to promote circulation of the cooling air about the product. For example, United States Patent No. 4,770, 339 to Weimer discloses a ventilated, stackable grape box. The sides and ends of the container have openings to facilitate venting.

United States Patent No. 5,593,087 to Ross et al. discloses a container having an open top and stacking projections near the corers at the top which engage corresponding recesses in the bottoms of similar containers when stacked. Similar stacking tabs and recesses are employed in United States Patent No. 5,002,224 to Muise.

A one-piece grape box is disclosed in United States Patent No. 5,370,303 to Fry.

Other ventilated shipping containers are disclosed in United States Patent Nos. 4,709,852 to Stoll, 5,458,283 to Southwell et al., 5,690,275 to Bose et al., 5,947,292 to Chelfi and 5,890,590 to Blomfield et al.

However, while some prior art containers have a plurality of openings for ventilation, they do not ensure sufficient flow of air when the containers are stacked. For example, the 20 containers may be stacked in an arrangement where adjacent rows have the containers arranged at right angles to each other. This is often done so that the containers fit on standard pallets required for shipment by truck or ship. When this occurs, the containers of the second row may block openings in the containers of the first row, which is the row closest to the source of ventilating air. The result is an inadequate flow of cooling air 25 through the containers which considerably slows the cooling rate.

Accordingly, it is an object of the invention to provide an improved container for produce or the like with better ventilation than prior art containers.

-3- It is another object of the invention to provide an improved corrugated paperboard container which can satisfactorily replace wooden containers used for grapes or other produce.

it is a further object of the invention to provide an improved corrugated paperboard container which is rugged and rigid in construction and economical to produce and sell.

SUMM0ARY OF THE INVENTION In accordance with these objects, there is provided, according to one aspect of the invention, a ventilated container having a rectangular bottom panel. First and second end panels are connected to the bottom panel and extend outwardly therefrom. First and second side panels are also connected to the bottom panel and extend outwardly therefrom. The side panels are connected to adjacent end panels. .A first side panel has a first longitudinal passageway extending therthrough from the first end panel to the second end panel to permit air to pass from the first end panel to the second end panel.

Preferably the end panels have first apertures aligned with the first passageway, whereby the ~.first passageway communicates through the end panels.

in one example the second side panel has a second longitudinal passagewvay extending therethrough from the first end panel to the second end panel and the end panels have apertures aligned with the second passageway whereby the secdnd passageway communicates outwardly through the end panels.

25 Alternatively the passageways may be in the end panels.

*.There is provided, according to another aspect of the invention, a blank for forming a container. The blank has a central, bottom panel. End panels are connected to opposite ends of the bottom panel along parallel fold lines- Side panels are connected to opposite sides of -4the bottom panel along parallel fold lines.' Each side panel has a first section adjacent to the bottom panel, a second section located outwardly therefrom and a connecting section extending between the first section and the second section. When the blank is folded along the fold lines of the side panels, each of the side panels is double walled with a passageway between the first section and second section thereof. Alternatively the end panels may have a first said section, a second said section, and a said connecting section such that the end panels are double walled with passageways therein.

There is provided, according to a further aspect of the invention, an appar atus for assisting cooling of produce. The apparatus includes a plurality of containers. Each container has a bottom, a first side, a second side, a first end, a second end and a longitudinal air passageway extending through the first side from the first end to the second end. The containers are arranged in a first row and a second row which is adjacent to the first row. The first row is arranged with the sides of the containers adjacent to each other and the second row is arranged with the ends of the containers adjacent to each other and with corresponding sides thereof adjacent to the second ends of-the containers of the first row. The corresponding sides of the containers of the second row have openings aligned with the passageways of the ~:containers of the first row, whereby passing through the passageways of the containers of the first row can enter the containers of the second row through *said openings.

Alternatively the passageways may be in the ends -of the containers.

According to a still further aspect of the invention, there is pro-vided a method of folding a corrugated paperboard blank having a bottom panel, opposite side panels and opposite end panels, said'side panels and said end panels being connected to the bottom panel- The 25 method comprises folding at-least one of the side panels to form a passagewaytheretbrough extending between the end panels. Alternatively at least one of the end panels may be folded to form a passageway extending between the side panels.

According to a still further aspect of the invention, there is provided a method of stacking produce containers. Each container has a bottom, a first side, a second side, a first end, and a second end, the sides and the ends being connected to the bottom, the sides having longitudinal passageways extending therethrough. The containers are stacked vertically in a first stack of horizontal rows and a second stack of horizontal rows, the first stack having sides of the containers adjacent to each other, the second stack having ends of the containers adjacent to each other with the first sides of the containers of the second stack being adjacent to the second ends of the containers of the first stack and with the openings in the first sides of the containers of the second stack being aligned with the passageways through the sides of the containers of the first stack. Alternatively the passageways may be in the ends of the containers and the containers stacked so the passageways in the first stack align with openings in the ends of the second stack.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIENTS Referring to the drawings and first to Figure 1 -Figure these show an apparatus 20 for assisting the cooling or ventilating gr-Apes, other produce or other perishable items. The apparatus includes a plurality of identical containers 22, five of which are shown in Figure 1 and Figure 2. As shown also in Figure 6-Figure 9, each of the containers has a rectangular bottom panel 24, a first upright panel 30, a. second upright panel 312, a third upright panel 26 and a fourth upright panel 28. In this example panels 30 and 32 are first and second side panels -respectively while panels 26 and 28 are first and second end panels respectively. The upright panels in this example are perpendicular to the bottom panel but they may extend at a different angle in -other embodiments. The first and second side panels 30 and 32 are connected to the first and second end panels 26 and 28 at corners 29, 3 1, 33 and 35 of the container as shown for the right, front container of Figure 1. The container 22 is open-topped though the invention is applicable a well to containers with tops. In this context, '"rectangular" with reference to the bottom also includes square bottoms.

Each side panel of this embodiment has. a longitudinal passageway extending therethrough.

Side panel 30 has a passageway 36, -while side panel 32 has a passageway 38. The passageways extend from the first end panel 26 to the second end panel 28 to permit air to pass from the fir;t end panel to the srcond end panel through each side of the container. In this example each side panel has a passageway although in alternative embodiments only a single side panel may have a passageway. The passageways in this embodiment are triangularas seen in Figure 8. However the passageways could be alternative shapes in other embodiments. Also the passageway or passageways may be in one or more end panels instead of, or in addition to, passageways in one or more side panels.

As shown best in Figures 3 and 6, each end panel has an aperture 40 Which is aligned with passageway 38 of side panel 32 and an aperture 42 aligned with the passageway 36. In this manner, the passageways communicate outwardly through the end panels.

As shown best in Figure 9, each of the side panels 3 0 and 32 includes an inner wall 48 and an outer wall 50 as shown for side panel 32. These are spaced-apart to form the passageways 36 and: 38. Each of the side panels has an upper edge 52. The inner wall 48 and the outer wall 50 are spaced-apart adjacent the upper edge. There is a connecting wall 54 which connects the inner wall 48 and the outer wall 50 adjacent to the upper edge. This connecting wall forms the third side of the triangular passageways 36 and 38.

As seen best in Figure 8, each of the side wall has a pair of apertures 60 and 62 extending through both the inner wall and the outer wall thereof. In alternative embodiments there may be fewer or more such apertures. Bottom 24 has a plurality of apertures 66, shown in Figure 7, which likewise assist in cooling. There are four such apertures in this embodiment although the number can vary. Similarly each of the end panels has an aperture 68 as seen.

for end panel 28 in Figure 9 and for end panel 26, in Figure 6.

The container has an upward -projection 70 at each corner which is L-shaped when seen in plan in Figure 7. Each of these projections has a pair of sloped edges 72 -and 74 in this example as shown in Figures 6 and 8. There are corresponding, similarly shaped recesses 78 at each corner of each container below each projection 70. The recesses have similar *shapes to the projections so that the containers lock together when stacked upon each other- Each of the recesses 78 has sloped'edges 80 and 82, shown in Figures 6 and 8, corresponding to sloped edges 72 and 74 of the projections 70. The sloped edges assist in fitting the .4.containers together when they are stacked one up on the other as shown in Figure ~Each side of the container has a pair of upward projections, 86 and 88, shown in Figure 8, w.hich are generally rectangular in shape with rounded corners. There are similar shaped -9recesses 90 and 92 on each side below the projections 86 and 88. These mating projections and recesses also assist is locking the containers together when they are stacked one upon the other.

Figure 10 shows a plurality of containers 22 which are arranged in two stacks 96 and 98, each stack having in this example three horizontal rows 100, 102 and 104 of containers. The containers of stack 96 are arranged with sides 30 and 32 of the containers adjacent to each other and with their first ends 26 facing outwrardly. The second stack 98, located behind the first stack 96, is arranged with ends 26 and 28 of the containers adjacent to each other and with sides 310 thereof adjacent to the second ends 28 (not shown in Fig. 10) of the containers of the first row.

Figure 1 shows -three containers of a single row of stack 96 and- two containers of a single row of stack 98- These are shown in Figure 2 from the opposite side. Ends 26 of the containers of stack 96 face the source of ventilating air, typically a cooling fan. This air enters each of the containers 22 in stack 96 through the opening 68 in end panels 28 as indicated by arrows 1 10. However, more significantly, cooling air enters passageways 3 6 and 38 ofthe sides 30 and 32 through apertures 40 and 42 in each of the end panels 26. -This is illustrated by arrows 114 and 116 in Figure 3I The cooling air passes through the passageways towards the second ends 28 of the containers as illustrated by arrows 120 and 122. in Figure 2.' As may be seen in Figure 1, each of the side walls has apertures 60 and 62 positioned so that one of these apertures aligns with apertures 40 and 42 in the end walls and accordingly with 25 thepassageways 3.6 and 3 8 in the side walls of the containers of stack 96. The apertues and 42 are not seen in Figure 1, but it may be seen that aperture 62 in the right container 22' CC is aligned with side walls 30 and 32 of the two right end containers 22 of row 96. Thus air passing through the passageways in the side walls 30 and 32 of these containers can pass through the aperture 62 as indicated by arrows 120 in Figure 1. Likewise arrows 122 illustrate the flow of air out of aperture 60 on wall 30 of the left container in stack 98.

The ventilating air entering the passageways 36 and 38 of the containers of stack 96 is permitted to enter the containers 22 of the stack through the apertures 60 and 62 as indicated by arrows 130 in Figure 2.

Figure 5 shows a corrugated paperboard blank 132 for forming each container 22. Each blank has a rectangular bottom panel 134 which forms the bottom 24 of the container as shown in Figure 6. There are end panels 136 and 13 8 which are connected to opposite ends of the bottom panel along parallel fold lines 140 and 142. In this example the fold lines are formed by spaced apart slits in the layers of paper of the corrugat ed paperboard farning blank 132.

There are side panels 148 and 150 connected to opposite sides of the bottom panel along parallel fold lines 152 and 154. Each of the side panels has a first section 160, as shon for panel 148, defined by fold line 152 and another fold line 162.. A second section 161 is :defined by fold line 164 and outer side edge 166 of the blank. It may be seen that the first and second sections of each.side panel are spaced apart by a connecting section 170 located between sections 160 and 161. 'When the blank is folded along the fold lines 152, 162 and 164, the first section 160 and the second section 161 of each of the side panels forms outer wall 50 and inner wall 48 of the side panels of the container as shown in Figure 9.

Each of the side panels, for example jide panel 150 of Figure 5, has a pair of first end flaps 180Oand 182 at opposite~ends ofthe first section 160. These are defined by fold lines 184 and 186 which are parallel to the fold lines 140 and 142 of the end panels. These flaps have openings 188 and 190 which form the openings 40 and 42 shown in Figure 3.

11 The first section of each side panel has openings 196 and 198 while the second section has aligned openings 200 and 202. These form openings 60 and 62 in the side panels when the container is folded along the fold lines to form the container as shown in Figure 8.

The second section 161 of each of the panels has second end flaps 210 and 212 which are connected to the second section Along fold lines 214 and 216 which are parallel to fold lines 184 and 186, but are spaced inwardly therefrom.

Each of the end panels has cut out portions 220 and 222, shown for panel 13 8 in Figure which align with passageways 36 and 38 when the carton is folded as- shown in Figure 9.

These allow air to pass through the end panels into the passageways.

When the blank is folded to form the containers, the flaps 180 and 182 extend along the exterior of the end walls to strengthen the end walls as shown for flap 182 in Figure 7. The.

flaps 210 and 2 12 extend along the insides of the end walls to strengthen the end walls as shown for-fiap 212 in Figure 7.

The flaps are held in position in this embodiment by hot glue although other adhesives or fasteners could be employed, 'Likewise the inner w alls 48 of the side panels, shown in Figure.

9, could be held in place at the bottoms by hot glue although glue or other fastening means is not used in the ilustrated emnbodiment. Also other means such as adhesives, fasteners, tabs and slots or friction could be used.

Figure l 1 shows a paperboard blank 300, according to an alternative embodiment of the invention, which is generally simnilar -to the previous one and thus will be described only in relation to the differences. In this example, it is end panels 302 and 304 which have inner.

and outer sections 306 and 308 with connecting section 3 10 therebetween. Thus, when folded up, the passageways are in the end panels rather than the side panels as in The previous.

embodiment- The end panels are connected to bottom panel 3 12 along with side panels 314 -12and 316. Also there is but a single central, upward projection 320 on each end panel and a single corresponding recess 322. The openings 330 in the side panels are in the form of recesses extending inwardly from the top edges 332 thereof Otherwise the structure is similar to the previous embodiment It will be understood by someone skilled in the art that many of the details described above are by way of example only and are not intended to limit the scope of the invention which is to be interpreted with reference to the following claims.
