Abstract
Description
- The present invention is related to the stackable plastic containers frequently used for the storage and conveyance of agricultural, industrial or any other type of products which structure allows to reduce weight significantly without reducing resistance or storage volume thereof. Additionally, the invention also relates to a method for stacking at least two plastic containers.
- In the packaging and conveyance industry, specifically horticultural products, the use of plastic containers of rectangular or square box type which are manufactured by plastic injection, is frequent.
- Said containers are formed by a bottom attached to four perimeter walls wherein said bottom and said walls have a frame structure allowing the air to circulate into the container and allowing a weight decrease of the structure.
- The corners of the containers often have a higher thickness and comprise reinforcing elements such as ribs to resist tensile, compressive, bending and torsional stresses, to which this type of containers are generally subjected during handling and transportation. Additionally, some wall and bottom portions also include reinforcing in order to avoid sag and to maintain stiffness of the structure.
- Other feature of this type of containers is that they have media such as edges and protrusions in their corners, which allow the stacking with identical containers and thus they can be stacked for storage or transportation in pallets.
- An example of this type of containers is the one disclosed in document
EP 0041307 , which describes a box moulded by injection for transporting fruit. - Another example of this type of containers is illustrated in
Figure 1 , which corresponds to a plastic container of the state of the art used for storing and transporting products such as tulip and lilium bulbs. - A disadvantage of this type of containers is its high weight of 1600 grs approximately.
- Therefore, the objective of the present invention is to provide a container which by means of less amount of material used and through an improved structure achieves a significant weight reduction and less use of material compared to the state of the art containers, without reducing the container resistance and the storage volume, and at the same time it reduces production costs.
- Another objective of the invention is to provide an improved container being compatible with the current containers allowing stacking in a stacked configuration.
- Still another aim of the invention is to provide an improved container being compatible with fastening means of the automated production systems.
- The present invention consists on a stackable plastic container for the storage and conveyance of agricultural, industrial or any other type of products, configured by a preferably rectangular base and by four vertical walls.
- Advantageously, in the connection of the vertical walls at the inner face of the container a cylindrical tubular column is disposed, which is open at its ends and is connected to the bottom structure. Being cylindrical said column provides a great resistance to the structure and its connection to the lateral walls and with the bottom end enable the forces, to which the container is submitted, to be distributed to the four columns in order to resist said loads and to prevent deflections.
- Being hollow the tubular columns allow a significant reduction in the use of material compared to the known containers and consequently, a relevant reduction of the container total weight since there is no need to use multiple ribs in the vertical walls (see
Fig. 1 ), which increase significantly the container weight. By the other hand, the volume generated by the presence of the columns inside the container is offset by a reduction in the bottom height, thus not affecting the useful final volume inside the container. - The lower part of each tubular column is entirely connected to a vertical projection running throughout the lower frame of the container base. By means of said projection it is possible to stack the present container both with identical containers and with the containers known in the state of the art, as illustrated in
Figure 1 , so that the projection fits in the upper corner of the container positioned at the bottom. - Another feature enabling to avoid the loss of strength of the container structure reducing its weight is connected to the upper edge of the longitudinal container walls having an extension to provide a better sag resistance.
- Moreover, the column height inside the container is selected such that it does not interfere with the operation of the machines grooves used for handling the containers in a plant, which are generally designed to operate with the standard thickness of this type of containers.
- The present invention also comprises a method for stacking plastic containers for the storage and transport of agricultural products, wherein said method comprises the following steps:
- a. To have at least two containers as the one described hereinafter.
- b. To place a first container supporting the lower projection in a surface.
- c. To place a second container onto the first container arranging its lower projection within the upper perimeter edge of the lower container, connecting the outer face of the lower projection of the upper container respectively with the inner face of the upper perimeter edge of the lower container.
- d. To support the vertexes of the perimeter frame of the upper container on the flat vertexes of the lower container.

Figure 2 illustrates an isometric view of the container of the invention. -
Figures 3 and4 illustrate details of the column of the container of the invention. -
Figure 5 illustrates a detail of the lower projection and its connection to the column of the container of the invention. -
Figure 6 illustrates a detail of the upper edges and the bottom of the container of the invention. -
Figure 7 illustrates a configuration of two stacked containers. -
Figure 8 illustrates a corner cutting of two stacked containers. - According to
Figure 2 , there is a container which comprises abottom 100, longitudinalvertical walls 200 and cross-sectionalvertical walls 300, wherein the attachment of each longitudinalvertical wall 200 to the cross-sectionalvertical wall 300 is reinforced by means of atubular column 400 cylindrical in shape. - According to a preferred embodiment of the invention, the container walls have
columns 210 andbeams 220 preferably flat, which supportvertical reinforcements 211 andhorizontal reinforcements 221 which are perpendicularly connected. Moreover, the vertical walls comprise anupper perimeter edge 500 running throughout the container upper perimeter. - On the other hand, the
bottom 100 is configured from a perimeter frame 110 (seeFig. 5 ) which encloses a grid structure arranged on T shaped ribs preferably and diagonally connected to each other. - According to
Figures 3 and4 , thetubular column 400 is vertically extended inside the container at each corner up to a height preferably less than the upper end height, where theupper perimeter edge 500 is disposed. Moreover, saidtubular column 400 is attached to twoperpendicular plates 412 by the inside of the container, which in turn are attached to the vertical walls forming a single piece. - Advantageously, the portion of the column positioned inside the container comprises a
recess 410 and in the upper face ahole 411 is configured. Said recess 410 together with the vertex formed by theupper perimeter edge 500 allows stacking with a container stacked at the top and it does not interfere with the grooves of the automated machines. - According to
Figure 5 , thetubular column 400 has alower extension 420 cylindrical in shape, being saidlower extension 420 attached to alower projection 230 consisting of a bottom perpendicular element protruding from theperimeter frame 110 at the bottom, and which connects the lower part of eachtubular column 400. - According to the embodiment illustrated in
Figure 6 , the container has its maximum height in the vertexes in order to promote the stacking of said points with other containers in a stack. Near the upper vertexes theupper perimeter edge 500 is tilted, in order to form then aflat vertex 510 protruding above therecess 410 of thetubular column 400. Moreover, advantageously theupper perimeter edge 500 has anextension 520 on a portion of the longitudinalvertical walls 200 providing a higher resistance to the structure avoiding the walls sag. - Still on
Figure 6 , it can be seen that thebottom 100 hasbottom recesses 430 generated by the decrease of the bottom ribs height wherein according to a preferred embodiment, saidbottom recesses 430 are positioned in the portion in contact with the vertical walls, thus forming an "X"shaped bottom structure 100. - The stacking method of two containers according to the invention and in reference to
Figures 7 and8 , consists of placing a first container supporting thelower projection 230 in the soil surface, of a pallet, etc. The second container to be stacked in the lower part of said first lower container, is placed such that thelower projection 230 of the second container is arranged within theupper perimeter edge 500 of the first container, so that the outer face of the lower projection of the second container contacts the inner face of the upper perimeter edge of the first container. - By means of the above mentioned, the vertexes of the
perimeter frame 110 of the upper container are supported on theflat vertexes 510 of the lower container, maintaining the walls (200, 300) aligned and consequently thetubular columns 400. - According to
Figure 8 , the stresses produced by the upper container weight are transferred by theperimeter frame 110 towards theflat vertexes 510 of the upper perimeter edge of the lower container and subsequently they are resisted by thetubular columns 400 which distribute the load towards the vertical reinforcements, to thehorizontal reinforcements 221 and to thebottom ribs 120. By means of this configuration, all the stresses are distributed to all the container dimensions and channeled to the lower extension (420) of the container placed further down. - According to an example of the present invention, a container with the same size of the state of the art containers, was constructed, this is 600 mm in length, 400 mm wide and 240 mm high. It was observed that due to the elements forming the structure of the container of the invention, a reduction of 20% of the weight was achieved without significant loss of resistance and enabling to form a containers stack comprising a combination of containers from the state of the art and from the present invention.
