Transport box

Abstract

A transport box has a one-piece container, which has a base and walls extending from the base and delimiting a transport chamber. The container consists of particulate foam made of expanded polypropylene (EPP), which has a plurality of foam particles sintered to each other, wherein the foam particles each comprise an outer wall and a substantially hollow inner chamber enclosed by the outer wall. The outer walls of the foam particles at the inner faces of the container which delimit the transport chamber are thicker than in the remaining regions of the container and form an inner skin on the container.

1 . Transport box having a one-piece container ( 12 ) having a bottom ( 16 ) and walls ( 18 ) that extend from the bottom ( 16 ), delimiting a transport space ( 20 ), which container consists of a particle foam material composed of expanded polypropylene (EPP), which has a plurality of foam particles sintered to one another, wherein the foam particles have an outer wall, in each instance, and an essentially hollow interior space enclosed by the outer wall, wherein the outer walls of the foam particles are thicker at the interior surfaces ( 22 ) of the container ( 12 ) that delimit the transport space ( 20 ) than at the other locations of the container ( 12 ), and form an inner skin ( 24 ) on the container ( 12 ). 
     
     
         2 . Transport box according to  claim 1 , comprising a one-piece lid ( 14 ) for closing off the transport space ( 20 ), which lid consists of a particle foam material composed of expanded polypropylene (EPP), which has a plurality of foam particles sintered to one another, wherein the foam particles have an outer wall, in each instance, and an essentially hollow interior space enclosed by the outer wall, wherein the outer walls of the foam particles are thicker at the interior surfaces ( 22 ) of the lid ( 14 ) that delimit the transport space than at the other locations of the lid ( 14 ), and form an inner skin ( 24 ) on the lid ( 14 ). 
     
     
         3 . Transport box according to  claim 1 , wherein the outer walls of the foam particles at the interior surfaces ( 22 ) of the container ( 12 ) and, if applicable, the lid ( 14 ) are at least twice, preferably at least three times, and ideally at least seven times as thick as at the other locations of the container ( 12 ) and the lid ( 14 ), respectively. 
     
     
         4 . Transport box according to  claim 1 , wherein the outer walls of the foam particles have a thickness of at least 0.2 mm at the interior walls ( 22 ) of the container ( 12 ) and, if applicable, of the lid ( 14 ). 
     
     
         5 . Transport box according to  claim 1 , wherein the pores situated between the foam particles have a maximal size of 0.2 mm on the interior surfaces ( 22 ) of the container ( 12 ) that delimit the transport space ( 20 ) and, if applicable, of the lid ( 14 ). 
     
     
         6 . Transport box according to  claim 2 , wherein the container ( 12 ) has a circumferential rim ( 26 ) on the upper edges of the walls ( 18 ), wherein the lid ( 14 ) has a circumferential groove ( 32 ) for accommodating the rim ( 26 ), wherein a bottom surface ( 34 ) of the accommodation groove ( 32 ) is intended for making contact with a contact surface ( 36 ) of the rim ( 26 ), and wherein the inner skin ( 24 ) of the container ( 12 ) extends over the contact surface ( 36 ), and the inner skin ( 24 ) of the lid ( 14 ) extends over the bottom surface ( 34 ). 
     
     
         7 . Transport box according to  claim 1 , wherein the distance between two walls ( 18 ) of the container ( 12 ) that lie opposite one another, in each instance, increases in the direction away from the bottom ( 16 ). 
     
     
         8 . Transport box according to  claim 1 , wherein the walls ( 18 ) are connected with the bottom ( 16 ) by means of film hinges ( 46 ) and are foldable into a transport position, in which they are disposed essentially parallel to the bottom ( 16 ). 
     
     
         9 . Transport box according to  claim 8 , wherein the inner skin ( 24 ) of the container ( 12 ) extends to cover the film hinges ( 46 ). 
     
     
         10 . Transport box according to  claim 1 , wherein the container ( 12 ) has grooves ( 48 ) in its bottom ( 16 ), on the interior surface ( 22 ) of the latter, over the surface of which grooves the inner skin ( 24 ) extends. 
     
     
         11 . Transport box according to  claim 1 , wherein the container ( 12 ) has a depression ( 38 ) that extends to the upper edge of the wall ( 18 ), in each instance, in two walls ( 18 ) that lie opposite one another. 
     
     
         12 . Transport box according to  claim 2 , wherein the container ( 12 ) has a recess ( 42 ) on each edge ( 40 ) that connects two walls ( 18 ) with one another, for grasping below the lid ( 14 ).
