Single-material package for containing fruit and vegetable produce with lid

Abstract

This consists of six pieces: a bottom ( 1 ), two side pieces ( 2 ), ( 2′ ) and two ends ( 3 ), ( 3′ ), and a lid or top ( 4 ), all made of medium or high density wood fiber and that can be assembled by means of a number of tabs ( 11 ) and ( 29 ) emerging from some of said pieces and which couple by a tongue and groove system to respective slots ( 19 ) and ( 17 ) made in other pieces. The box has stacking means which are materialized in upward extensions ( 20 ), ( 20′ ), ( 24 ), ( 24 ′) of the upper ends of the side pieces and of the ends, determining oblique edges, coinciding with notches of the same shape made in their lower edges, which allow these to be self-centring. The free outwardly-projecting ends of the securing tabs constitute a spacer between boxes, which when these are palletised means that conduits are formed to facilitate air circulation between them.

1 . Single-material package for containing fruit and vegetable produce with lid, of the sort that incorporate holes for aeration and means for stacking, characterized by consisting of five pieces of MDF (medium or high density fiber) or some other similar product, these pieces consisting of a bottom ( 1 ), two side pieces ( 2 ), ( 2 ′), two ends ( 3 ), ( 3 ′), and a top ( 4 ), fitted with securing means by tongue and groove coupling, these means specifically being a plurality of tabs ( 11 ) and ( 29 ) which emerge from some of said pieces and which are coupled to respective slots ( 19 ) and ( 17 ) made in other pieces, said top ( 4 ) being able to be coupled to its mouth, so that after being coupled it prevents the contents of the content from spilling out if this is turned over.  
   
   
       2 . Single-material package for containing fruit and vegetable produce with lid, according to  claim 1 , characterized in that said tabs ( 29 ), present in the lateral edges of the box ends ( 3 ), ( 3 ′), are in the shape of a trapezium, whose larger base has a length identical to the slot to which this is coupled, with a small notch ( 30 ) in its lower edge, with a width according to the thickness of the part to which this is to be coupled, which generates a tooth ( 31 ), so that after inserting the tab into the slot, this locks into the side piece by pressing the box end downwards.  
   
   
       3 . Single-material package for containing fruit and vegetable produce with lid, according to  claim 1 , characterized in that at least one of said tabs ( 29 ) incorporates in its upper edge a wedge ( 32 ), which after being coupled to the slot ( 17 ) by elastic deformation, prevents the end from coming apart.  
   
   
       4 . Single-material package for containing fruit and vegetable produce with lid, according to  claim 1 , characterized in that said tabs ( 11 ) have a trapezium shape, with a chamfered and rounded presentation zone ( 12 ) which helps to position this against the corresponding slot, an expansion zone ( 13 ), slightly longer than said slot, and an inverse trapezium zone ( 14 ), with a transversal length equal to the thickness of the part that receives this, with its narrowest zone having the same longitudinal coordinate as the receiving slot.  
   
   
       5 . Single-material package for containing fruit and vegetable produce with lid, according to  claim 1 , characterized in that said means for proper stacking are materialized in upward prolongations of the upper ends of the box side pieces ( 2 ), ( 2 ′) and of the box ends ( 3 ), ( 3 ′), determining oblique edges ( 20 ), ( 20 ′), ( 24 ), ( 24 ′), coinciding with notches of the same geometry made in its lower ends ( 21 ), ( 21 ′), ( 25 ), ( 25 ′), so that the stacked boxes fit together through said oblique edges, with a self-centring effect determined by their own weight.  
   
   
       6 . Single-material package for containing fruit and vegetable produce with lid, according to  claim 1 , characterized in that said lid ( 4 ) is coupled to the box by means of small tabs ( 37 ) which come out of the middle zone of its smaller sides, for coupling by means of bending through the oval-shaped holes ( 34 ), said lid being able to be used as a handle by means of its holes ( 35 ).  
   
   
       7 . Single-material package for containing fruit and vegetable produce with lid, according to  claim 1 , characterized in that said lid ( 4 ′) is coupled to the body of the lid by means of projections ( 42 ) outwardly extending from the ends of its larger edges, for engaging in slots ( 43 ) operatively arranging on sides ( 2 ′).  
   
   
       8 . Single-material package for containing fruit and vegetable produce with lid, according to  claim 1 , characterized in that the free outwardly-projecting ends of the securing tabs ( 29 ) as well as the distance existing between the slots ( 17 ) and the edge of the side pieces ( 16 ), ( 16 ′), constitute a spacer between boxes, which when these are palletised determine conduits ( 41 ) between them, facilitating air circulation between the boxes.
