Definitions

  • the present invention relates to a bin for storage of loose materials.
  • the bin in reference is intended for agricultural or industrial uses for receiving bodies or goods of different typologies such as, for example, fruit, vegetables, pulses, fruit juices or pulp, fluids for industrial use or industrial goods of relatively reduced sizes as compared with the bin sizes.
  • bins must meet some requirements such as maximizing of the usable inner volume, in order to optimize transportation and storage costs under the same overall-bulkiness conditions of the bin, as well as reduction in weight and more specifically reduction in the amount of raw material used for making them, so that the production costs (raw material, energy consumption) are reduced as much as possible.
  • bins in reference typically have sizes in the order of about 1-1.5 m 3 and are therefore subjected to heavy structural loads, in case of filling with goods the specific gravity of which is usually close to that of water.
  • bins which are provided with side walls suitably equipped with stiffening column-shaped structures at the central regions of each face, and with horizontal or inclined ribs typically extending parallelly of each other, at the upper edge.
  • moulds provided with shaped portions are to be compulsorily used, so as to define the necessary undercuts for formation of the side walls.
  • the bin shown in Fig. 1 surely does not possess an even inner surface, which is adapted to prevent possible damages to the contents thereof (above all if it is fruit) and not to hinder emptying operations of the bin itself even if they are carried out by partial overturning of same.
  • the side wall areas in which hollows are made by means of corresponding undercuts surely do not involve geometrical patterns providing smoothed shapes and typically constitute goods-accumulating regions of difficult cleaning and more generally where the goods are likely to stagnate.
  • bins similar to the one shown in Fig. 1 hardly lend themselves to be used for food applications where, due to sanitary purposes, as much as possible smooth inner and outer surfaces are required in order to carry out cleaning and sterilizing operations of the containers in a simple and reliable manner.
  • the technical task underlying the present invention is to provide a new bin typology capable of substantially obviating all drawbacks typical of the prior art.
  • a bin for storage of loose materials i.e. not provided with rigid packages of their own, has been generally identified by reference numeral 1.
  • bin 1 will be adapted for use in the agricultural or food field for receiving a great number of typologies of goods such as fruit, vegetables, mashed fruit or vegetables or fruit or vegetables juices and/or pulps and still other goods; alternatively, for industrial-scale uses the bin in reference will be adapted for storage of generally unpackaged liquids, fluids or solid pieces.
  • Bin 1 conventionally comprises a base wall 2 of polygonal shape, preferably having a rectangular or square conformation with a perimetric edge 3 from which a side wall 4 vertically emerges.
  • the side wall 4 and base portion 2 define a holding space 5 of predetermined volume within which the material to be stored can be put.
  • the side wall 4 also has an upper rim 4a delimiting an access opening for loading and unloading of the material intended for stowing in the holding space 5.
  • the bin side wall has an outer surface 6 of substantially prismatic conformation defined by a predetermined number of faces 7 angularly consecutive to each other, as well as an inner surface 8 facing the holding space 5 and opposite to the outer surface 6.
  • the side wall 4 can be provided or not with through slits 9 (see Fig. 7, for example), which are typically disposed on parallel lines in mutual side-by-side relationship and have the role of efficiently ventilating the bin contents, above all when the goods are stowed in cold rooms after harvesting.
  • the base wall 2 in turn, has an upper surface 10 facing the holding space, and a lower surface 11 which is provided with vertical strengthening ribs 12 disposed in a grid arrangement, as shown in Figs. 5, 10, 16, 19 and 20.
  • surface 11 could be equipped with rest feet or projections also disposed at the centre line of bin sides or, optionally, with a central foot.
  • bin 1 is also provided with radial stiffening means 15 in engagement with the inner surface 8 of the bin side wall 4 and at least extending between a connecting region 16 defined on the inner surface of a predetermined one of said faces and a corresponding connecting region 16 defined on the inner surface of another of said faces of the side wall.
  • the radial stiffening means is such shaped that it creates a mechanical connection between the connecting region 16 relative to one face and the connecting region 16 relative to an adjacent face.
  • the connecting regions 16 between which the radial stiffening means 15 mechanically interacts extend at a central area of the inner surface of each face.
  • the radial stiffening means 15 comprises a curved surface portion 17 extending at the connecting region 16 provided on each face, and a connecting length 18 substantially extending at angle regions of the side wall and interposed between one curved surface portion, corresponding to one face, and the curved surface portion corresponding to the consecutive face.
  • each of the faces defining the bin side wall has an inner surface partly (i.e. at a central region) defined by the curved surface portions 17 and partly (i.e. at the angle regions) defined by the connecting lengths 18 between a curved portion and the curved portion relative to an adjacent face.
  • each face has a surface defined by a substantially flat perimetric frame comprising opposite and flat side portions 19 extending vertically at the angle regions of the side wall and delimiting respective central areas 20 the shape of which, as shown in the drawings, matches that of the corresponding curved surface portions 17.
  • the last-mentioned surface portions, and therefore the corresponding central areas 20 as well, of the outer side surface are of cylindrical conformation having a vertical or possibly slightly inclined directrix and a generatrix shaped in the form of an arc of a circumference or an ellipse or more generally of a conic.
  • These curved surface portions 17 have a vertical extension substantially equal to that of the corresponding face of the side surface which, depending on the embodiments, can have one or more stiffening ribs 21 of horizontal or inclined extension at the end, close to the upper rim 4a.
  • each connecting length 18 comprises a thin wall having horizontally opposite ends 18a rigidly connected to corresponding end junction regions 17a of consecutive curved portions 17.
  • the connecting length can be defined by a flat thin wall, as shown in the embodiment referred to in Figs. 7 to 11, or by a thin wall of curved conformation, as shown in Figs. 2 to 6 and 12 to 21.
  • each connecting length 18, at the angle regions and in cooperation with the side wall defines auxiliary storage spaces 22, where a predetermined volume of goods to be stowed in the bin can be housed.
  • Preferably spaces 22 are delimited at the lower part thereof by a respective bottom wall 22a, which can be advantageously disposed below the bin base wall 2, that is substantially at the same level as the rest surface on the ground (see Fig. 11).
  • the bottom walls 22a placed on the ground floor are provided to be joined by respective connecting regions 22b extending on at least two opposite sides of the bin and substantially disposed on the ground floor as well (see Fig. 22).
  • the upper surface of the base wall 2 can be substantially flat or be provided with hollows at the angles (Fig. 11) or at opposite sides (Fig. 22).
  • the connecting length preferably has windows or passage openings 23 (see examples in Figs. 7, 12, 20) to bring each auxiliary space into communication with the holding space 5.
  • a thin wall 24 of vertical extension can be provided internally of spaces 22.
  • This wall 24 radially extends between each connecting length 18 and the side wall 4.
  • each connecting length 18 can define tubular column-shaped structures which are closed at an upper end and open at a lower end (see the embodiment referred to in Figs. 2 to 6, for example).
  • the bin can be advantageously provided with column-shaped structures defined by a vertical tubular wall in engagement with the side wall.
  • These column-shaped structures are preferably disposed in pairs at each angle region and define stiffening elements for stacking as well as rest regions for receiving corresponding feet when several bins are stacked up.
  • the side wall itself can have a tubular structure which is open at the lower part thereof and closed at the upper part thereof, still for defining column-shaped stiffening structures.
  • the connecting lengths 18 can also be formed of tapes or bands made separately of the bin and applied to the latter at the angle regions for mechanically connecting consecutive surface portions 17.
  • the added tapes or bands 18 can provide respective end portions 18a active, upon closure, on column-shaped structures similar to those described with reference to Figs. 7 to 11.
  • Figs. 24 and 25 are solutions in which the means 15 comprises thin, preferably flat, walls, each extending from one face 7 to one face 7 opposite or adjacent to the starting one.
  • the invention achieves important advantages.
  • the bin in accordance with the invention is particularly strong from a structural point of view as regards radial deformations.
  • the curved conformation given to the surface portions 17 and the continuity obtained with the connecting lengths 18 lead the bin side walls to substantially work by pulling instead of working by bending as it happened in bins of the traditional type.
  • auxiliary reinforcing structures such as ribs, for example are reduced to a minimum which will bring about a simplification of the bin itself and, as a result, a reduced complexity of the moulds required for bin production.
  • bin 1 is very evolutionary relative to the known art, because the side walls are brought to work in an optimal manner, thereby reducing the overall amount of material needed for manufacturing the bin in reference, the structural behaviour being the same.
  • the bin being the object of the invention represents an improvement relative to similar embodiments of the traditional type, because the geometry of the inner surfaces of the side wall is free from undercuts or sharp variations and because the connecting lengths or walls between adjacent curved portions define auxiliary storage spaces in which a great amount of goods can be housed.
  • the version of greater volume can be obtained by adopting solutions that do not require movements on the mould punch (solution in Fig. 2 or with added elements in Fig. 23).
  • bins can be of greater height than the conventional 700-800 mm height typical of traditional bins, without creating particular deformation problems during the operating step.
  • the possibility of avoiding ribs on the outer wall and/or undercuts on the inner side of the side wall generally involves a simplification in the structure of the mould intended for producing the bin.
  • moulds with a reduced opening stroke of the press can be planned for withdrawal of the workpiece from the mould, thereby enabling production of bins having big overall dimensions in height without resorting to apparatuses that have sizes that do not correspond to the standard ones present on the market and that, clearly, would be very expensive.
  • the bin is also very advantageously in its most specific aspects.
  • the possible absence of column-shaped structures at the angles not only enables the angle regions themselves to be utilized for receiving the goods, but in particular allows these angle regions to be utilized up to the rest surface on the ground, which will further increase the available inner volume.
  • the bin in reference is compatible, as regards stacking, with bin embodiments already present on the market, so that, for its use, the replacement of still usable bins of a traditional typology is not required.
