Description

For the pallet of fruit or vegetables

Technical field

The present invention relates to the pallet field be made up of corrugated fibreboard.Specifically, the present invention relates to this pallet of fruit or vegetables.

Background technology

Fruits and vegetables is transported to all over the world over long distances.Usually, fruit or vegetables are placed in pallet transport.Usually, these pallets are made up of corrugated fibreboard.

Nowadays, the Plaform provided by International Paper is the advanced design for the transport of fruits and vegetables and the pallet of displaying.In this Plaform designs, the corrugated fibreboard in tray bottom is arranged to these panels are extended on the longitudinal direction of this pallet.

Summary of the invention

The present inventor recognizes, the result in the panel direction of the corrugated fibreboard during this Plaform designs is, these long sidewalls are made up of the plate with horizontal panel, and the resistivity that this sidewall compares load from top to bottom with the sidewall with vertical panel is much smaller.In addition, the present inventor finds that the ventilation in stacking Plaform pallet is inadequate.

The object of this disclosure is to provide the pallet for fruit or vegetables, these pallets need relatively little corrugated fibreboard blank and effectively use in the meaning of these blanks be powerful and stable, can be stacking and cost-efficient.Another one object is to provide and allows when stacking, such as in transport or storage process, therefore its content available ventilation is carried out the pallet that cools.Another object is to provide the pallet (pallet formed in the machine) of a kind of machine erection.

Therefore, provide a kind of for fruit or vegetables, from the collapsible pallet of the smooth corrugated fibreboard of single-piece, this pallet comprises:

Have a bottom section of two long sides and two sides, wherein these panels of the corrugated fibreboard of this bottom section are parallel with these sides;

Two that extend from the long sides of these of this bottom section relative sidewalls; And

Two that extend from these sides of this bottom section relative end walls, wherein

Each sidewall comprises the two-layer corrugated fibreboard with horizontal panel,

Each end wall comprises a centre portion and is positioned at two flank sections of this centre portion flank, described centre portion be by individual layer have that the corrugated fibreboard of horizontal panel is formed and each flank section comprise ground floor and the second layer have vertical panel board fiber board and wherein

The height of this centre portion is less than the height of these two flank sections.

The smooth corrugated fibreboard of this single-piece (this pallet is folding thus to be formed) is commonly called blank in this area.

In the pallet of this disclosure, these walls, all parts of the load-bearing when stackable pallet, i.e. the flank section of these sidewalls and these end walls, comprises the two-layer plate with vertical panel.These walls, only these parts of being only made up of the plate with horizontal panel, i.e. the centre portion of these end walls, does not contact and not load-bearing substantially with the pallet above stacked body.For there is the pallet of length 600mm, width 400mm and height 170mm, compared with the only 1500mm designed according to this Plaform, disclosing these walls according to this is be made up of the 3380mm with vertical panel (be 3140mm according to Fig. 2, with multiple ventilation otch) plate.

Design with this Plaform or have compared with the another kind designing identical bottom panel direction with this Plaform designs, another benefit of the design of this disclosure reduces bottom deflection.

The present inventor recognizes, during the load of bearing from top to bottom when these centre portions are unnecessary, these centre portions alternatively can be designed to contribute to actv. and ventilate.Therefore, the height of centre portion is less than the height of flank section and makes air to pass end wall.When multiple stackable pallet body is placed adjacent one another in transportation, such ventilation is even more important, because all must control the temperature and humidity in these pallets to many products.

Another benefit reducing the height of centre portion is the length reducing the blank being folded to form pallet.If the height of centre portion is identical with the height of these flank sections, then for the most frequently used pallet dimension, the total length of blank will increase 8%.Therefore, the pallet of this disclosure can provide the plate consumption of 8% to reduce in pallet manufacturing process, and this is obvious in the field of relatively low profit.

In an embodiment of this disclosure, each flank section comprises the board fiber board that third layer has vertical panel further.In such embodiments, the height of this third layer is preferably less than the height of ground floor and the second layer.Usually, this means that the lower part of these flank sections is made up of three layers and the upper part of these flank sections is made up of two layers.

In a preferred embodiment, single end wall member constitutes the third layer of the flank section of this centre portion and each end wall.In such embodiments, the upper limb of this end wall member can be straight and level, this means that the height of this centre portion is identical with the height of the third layer of these flank sections.

Preferably, such end wall member extends from each side of this bottom section.Usually, each end wall member and this bottom section are separated by a fold line.

In an embodiment of this disclosure, in the flank section of these end walls, at least one in this ground floor and the second layer is arranged at outside third layer.Therefore, if be placed to by two pallets, their end wall is converged, then between these pallets in these between section place form empty space.If pile tray in this way, be then formed uninterrupted " air passage " that help stacked body and ventilate.When ground floor and the second layer are arranged at outside third layer, define wider air passage.

When in these flank sections, third layer is sandwiched between ground floor and the second layer, this ground floor and this second layer can be glued in this third layer respectively.When this ground floor and this second layer are all arranged at outside third layer, the only one in them can be glued in this third layer.In this case, this ground floor and this second layer can be glued together.

In the pallet of this disclosure, the width of centre portion can be such as 0.25-0.50 times of end wall width.

Preferably, the pallet of this disclosure comprises multiple handle.Usually, these handles are provided at the end wall place of pallet.Such as, handle can be formed by providing in the centre portion of each end wall an otch.These otch typically 7cm-14cm, such as 8cm-11cm are wide.In one embodiment, the width of this otch is less than the width of the centre portion of end wall.The height of these otch typically is 2cm-5cm, such as 2cm-4cm.The shape of these otch can be such as rectangle or ellipse.End/the turning of this rectangle can be sphering.Such as, these ends can be semicircles.

In an embodiment of this disclosure, this otch extends in this bottom section, exceed fold line between this bottom section and centre portion of this end wall.When providing such otch, therefore eliminate the part of this edge between the centre portion of this end wall and this bottom section.This of otch/handle is placed with the ventilation helping pallet in heaps, especially when air passage is by the one or both in this ground floor and the second layer being arranged in outside third layer in these flank sections.

This otch can such as to extend in this bottom section between 0.5cm and 5cm.In one embodiment, it to extend in this bottom section between 1cm and 3cm.

In addition, when this otch extends in bottom section, inside the centre portion of pallet in heaps, locate formation Vertical Channel.Such Vertical Channel is only blocked by the content of these pallets.If these contents are not close packing (larger fruits and vegetables are not this situation usually), then such Vertical Channel provides actv. and ventilates (see example 2).

These otch of this disclosure are preferably medially located in the end wall.That is, preferably identical to the distance at each edge end wall with sidewall in the middle part of otch.Therefore, these pallets keep balance when being handled upside down.

In an embodiment of this disclosure, in bottom section, these long side places provide multiple breather port.This type of breather port can mate with the ventilation otch in these sidewalls at the roughly same position place of the long side along bottom section.Preferably, this type of ventilation otch is positioned in the top place of these sidewalls and makes them near the breather port of above pallet in stacked body.When these ventilation otch have such position, eliminate a part for the upper limb of each sidewall.The degree of approach between these ventilation otch and breather ports above contributes in the ventilation of these pallets when stacking.

At each long side place, one or two or more breather port can be provided in bottom section.Equally, one or two or more ventilation otch can be provided in each side wall.In one embodiment, these breather ports and these ventilation otch are couplings along the position of the long side of bottom section.

In one embodiment, these breather ports in bottom section extend among these sidewalls.In another embodiment, the shortest distance from the edge of each breather port to one of these long sides is 1cm-4cm, such as 1cm-3cm.

In an embodiment of this disclosure, the height of centre portion is roughly identical with the width of each flank section or be less than this width.This means, in the blank forming this pallet, this part corresponding with the centre portion of end wall, such as single end wall member discussed above, does not contribute the total length of this blank.In other words, by keeping the height of centre portion roughly identical with the width of flank section or be less than this width, reducing the total length of blank, which save material and therefore provide cost savings.This also discussed hereinbefore.

In order to the load distributed from top to bottom on pallet in heaps, the height of these sidewalls can be roughly identical with the height of the flank section of these end walls.

Bottom section normally rectangle but can be foursquare in some embodiments.Such as, the length of each long side can be the 1.1-1.9 of the length of each side doubly, such as 1.3-1.7,1.4-1.6 or 1.5 times.Each long side can be such as 300mm-1100mm, such as 400mm-800mm, and each side can be such as 200mm-700mm, such as 250mm-550mm.

It is understood to one skilled in the art that under normal circumstances, two end walls have identical size and configuration, and two sidewalls have identical size and configuration.Equally, the length of two long sides of bottom section is normally identical and the length of two of bottom section sides is normally identical.
