Definitions

  • An object of the present invention relates to an expandable tray, where tray is understood to mean a container in the form of a tray formed by a base and several side walls emerging from each side of the base, where the tray has the property of having an expandable inner volume as a result of the expansion of the base with the side walls.
  • the present invention is characterized by the special configuration and design of the die-cut and cut cardboard sheet which is used to form the tray, thereby achieving an expandable tray which can furthermore be stacked since they can fit one inside another.
  • the present invention is comprised within the field of containers, preferably cardboard containers, having a configuration in the form of a tray.
  • Truncated pyramid-shaped product containers which can fit inside one another, such that they can be arranged in a fitted manner, in a smaller volume, are known in the state of the art. However, there is no known container which, while having the possibility of being able to fit one inside another, has the characteristic of increasing their inner volume.
  • Packages that can increase in volume as a result of a series of parallel fold lines in the folding area of the side walls with the base are also known in the state of the art.
  • all known packages with means such as those described have a right prismatic shaped configuration, which enables them to be arranged fitted one inside another.
  • an object of the present invention relates to developing a container that simultaneously has both characteristics, that is, on one hand, they can be fitted one inside another, thereby taking up a smaller volume when stacked, and they also have the particularity of being able to modify their inner volume as needed.
  • Document EP0240628A1 discloses a package apparatus (10) according to the preamble of claim 1, that includes a tapered, elongated carton portion, with a plurality of sides, and with lower portions (100,110,120) slit to define, while elongated, part of the package apparatus, and, when partially folded, legs on which the apparatus may be supported to comprise a free-standing vase, and when fully folded, a bouquet holder.
  • the object of the present invention is an expandable tray the inner volume of which can expand when exerting a force on the upper edge of the side walls once the tray is formed; the tray therefore has a base, which is preferably rectangular, and it can have as many sides as desired, from each side of the base emerging a series of sections that will form the side walls of the tray, and where at least two fold lines parallel to one another are arranged at the junction end of at least one of the side walls of the tray with the base.
  • a concavity is formed in each of the corners formed between contiguous sides of the base.
  • the number of side walls in the tray, as well as the number of parallel fold lines arranged on the side walls at their junction with the base are in no case limiting.
  • each side wall provided with the possibility of widening or being displaced in relation to the base allows having a double inner volume, one corresponding to folding the side wall with respect to the base by means of a first fold line and a second volume corresponding to folding the side wall with respect to the base by means of a second fold line.
  • the side walls When exerting pressure on the upper edge of the side walls once the tray is formed, the side walls will be displaced outwards, where the displacement takes place at the junction end of the side walls with the base, modifying its inner volume since the side walls are provided with several fold lines parallel to one another.
  • the side walls of the tray In order to fit one formed tray in another and be stacked, taking up a smaller volume, the side walls of the tray have a trapezoid-shaped configuration, which results in a final truncated pyramid-shaped configuration of the tray.
  • a container in the form of a tray which offers two very useful operating characteristics simultaneously is achieved, that is, on one hand, it is able to modify its inner volume based on the pressure exerted on the upper edge of the side walls once the tray is formed, and on the other hand, the trays can be arranged in a fitted manner one inside another almost in their entirety, which allows a stack with a smaller final stack volume, as a result of the trapezoid-shaped configuration of the side walls.
  • the die-cut and cut cardboard sheet which is used to form the tray can be seen, and as observed, it comprises a base (1).
  • the base (1) can have as many sides as desired, preferably four, like in the embodiment shown.
  • each side of the base (1) a trapezoid-shaped side wall which is narrower at the junction with the base than at its free edge, such that when the side walls are folded with respect to the base, a truncated pyramid-shaped assembly is formed which allows the fitted arrangement of one tray with respect to another.
  • the base (1) is rectangular and, therefore, there are four side walls, with there being two end walls (2) and two lateral walls (3).
  • the lateral walls (3) have extensions by way of flaps (3.1) which allow the junction with the end walls (2).
  • Closing flaps (3.2) are also arranged on the free edge of the lateral walls (3).
  • At least twofold lines are provided at the junction with the base on each side wall to be provided with the possibility of outward displacement of the side walls at their junction area with respect to the base.
  • Figure 2 shows a tray that is formed and filled with a series of objects in which due to the action of an outer pressure or force outer exerted on the upper edge of the side walls once the tray is formed, an outward displacement of the side walls with respect to the base (1) has occurred at the junction end of the side walls with the base (1), subsequently increasing the volume.
  • Figure 3 shows the advantageous stacking ability of the expandable tray (7) compared to another trapezoid-shaped tray design (9) in which the angle of inclination of its walls is less pronounced to increase its capacity.
  • the expandable tray (7) allows configuring its walls with an angle of inclination for stacking that optimizes logistics compared to other trays with the same capacity and height.
