Definitions

  • the present invention consists of a stackable plastic container with folding walls for the transport and storage of fruit and vegetable products, such as grapes, cherry, blueberries, among others.
  • the containers used for the storage and transport of fruits are preferably constructed of plastic material and are configured mainly from a bottom in connection with side walls, forming an interior volume in which is deposited the fruit and vegetable products to be stored and / or transported.
  • both the walls and the bottom of the box are formed from a framework structure which allows a significant reduction in the weight of the container, resulting in less manufacturing costs and better handling.
  • Said ribs of variable height have a "T" shape and the height of the lower portion varies to optimize the distribution of the stresses produced by the products arranged inside the container.
  • the nerves of variable height have their maximum height at the ends or corners of the bottom frame, area in which the greatest amount is demanded of efforts caused by the weight of the products inside the container.
  • the bottom consists of a mantle of varying height with zones of different geometry to efficiently distribute the efforts to which it is subjected and reduce its weight by lacking unnecessary material in its construction.
  • a drawback presented by the container of the application 0880-2014 is that when several identical units are stacked, for example in a pallet for storage and transport, the T-shaped ribs and specifically the lower vertical portion thereof tends to damage or leave marks on fruit and vegetable products arranged inside the container located just below. The above occurs due to the flexion of the bottom of the upper container product of the product's own weight or because the products of the lower container were poorly distributed by the operator, transcending the height of the walls and being in contact with the bottom of the upper container .
  • the technical problem that the present invention intends to solve is related to how to optimize the distribution of stresses in a container, minimizing its weight and the damage caused to the products contained in stacked containers, without compromising the resistance of the container .
  • the present invention consists of a plastic container with folding walls, which is formed by a bottom, two longitudinal walls and two transverse walls, said bottom being formed by a bottom frame attached to a bottom base, wherein said bottom base It consists of a network of rectangular stripes oriented diagonally to the background frame.
  • the width of the strips and their thickness vary according to the position of the strip at the bottom base and based on the stresses to which the container will be subjected.
  • the main stripes that cross the diagonals of the container and the stripes of the corners are reinforced by having a width greater than the remaining stripes.
  • the thickness on the sides of the bottom and especially at the corners gradually increases in relation to the remaining stripes.
  • This configuration allows to obtain a significant decrease in the final weight of the container, thanks to the reduction of material that is possible to obtain by means of the bands of variable width and height, obtaining a balance and transmission of optimized efforts and at the same time avoiding the damage from the bottom to the products contained in a lower container when they are stacked, since the underside of the strips is flat and aligned with each other in the horizontal plane.
  • the latter means that in the event that the bottom of a stacked container flexes slightly due to the weight of the products, said flexion of the bottom strips will not damage or mark the products that are stored in the container located below, thanks to the flat shape of its lower face.
  • the variations in width and thickness of the strips that make up the bottom of the container make the upper face of the container look like an irregular mantle whose geometry and design will depend exclusively on the efforts to which the container will be subjected, associated the weight, size and shape of the content to be stored, as well as the transport or storage conditions, which may be determined, for example, by results obtained by computer modeling and simulation tests.
  • the weight reduction achieved is extremely beneficial from the productive point of view, since it reduces the use of material for manufacturing, thereby also reducing costs and without losses in resistance or production compared to known containers.
  • the proposed container comprises a joining system such as that disclosed by Chilean patent application No. 00879-2014 which consists of a lightweight solution that allows to increase the strength of the joining means without meaning additional costs in both manufacturing and operation.
  • Said joining system comprises at least one clip-type closing device, wherein the closing device has at least one male closing means and one female closing means that join the longitudinal walls with the transverse walls.
  • the joining system comprises a hollow tubular column fixed to one of the walls of the container and integrated to at least one of the closing means.
  • Said column comprises a base that is fixed to the bottom and is configured so that the column is mounted on them at the junction between the walls of the container.
  • the base of the column comprises stacking means configured to fit with the column stacking means of another container.
  • the container comprises a strap system similar to that disclosed by Chilean Patent No. 52101, to improve the distribution of the stresses applied to the container in a full state.
  • Said rod system consists of 3 plastic braces distributed one in the center and two at each end of each longitudinal wall, which converge at their ends to a coupling means corresponding on one side of the container to a male type coupling means. and in the other to a female hooking means.

  • the main strips 122 that cross the diagonals of the container and the stripes of the corners 123 have a width greater than the remaining stripes, so as to reinforce the most tensioned areas of the container.
  • the thickness at the sides of the bottom 124 and especially at the corners 125 gradually increases for the same reason.
