  • agricultural produce such as fruit and vegetables.
  • Currently, such produce is transported in corrugated cardboard containers which have the disadvantage that when exposed to moisture the strength thereof is considerably reduced which results in crushing of the containers and damage to the contents thereof. Further, when the containers reach a required destination, e.g. a shop, the contents must be unpacked therefrom and transferred to a display rack.
  • the Inventor believes that the container in accordance with the invention will not be adversely affected by exposure to moisture. Further, the entire container can be positioned on a display rack thereby avoiding the need to transfer the produce from the container. By enabling the container to be collapsible, it can be reused several times with transport costs being reduced to a minimum by collapsing the container into its blank form as shown in the drawings. Further, the container blank is designed to be nestable to maximize the number of blanks that can be transported in a given volume thereby reducing the cost associated therewith.

Abstract

L'invention concerne un contenant (10) fabriqué à partir d'un matériau plastique synthétique. Ce contenant (10) comprend une base présentant une pluralité de côtés. Une paroi latérale (14, 16) est raccordée à chaque côté de la base (12) par l'intermédiaire d'un mécanisme charnière permettant de déplacer ces parois entre une position affaissée et une position déployée dans laquelle elles s'étendent vers le haut à partir de la base (12), de sorte qu'au moins une partie de chaque paroi latérale (14, 16) butte contre la base (12) en un point éloigné d'un bord de la base (12) vers l'intérieur. Ce mécanisme permet que des charges soient transmises entre les parois latérales (14, 16) et la base (12), au niveau de points espacés des bords de la base (12) vers l'intérieur. Le contenant selon l'invention comprend également un moyen de blocage servant à bloquer les parois latérales dans la position déployée. L'invention concerne encore une ébauche permettant de former ledit contenant.
