Vacuum-insulated stacking container for the temperature-controlled transport of food

Abstract

The invention relates to a stacking container (1) for the temperature controlled transport of food, comprising an outer container (3) with an outer container base (31) and an outer container wall (32) which are connected together so as to form a receiving area (33) which is open on one side. The stacking container (1) additionally comprises an inner container (2) with an inner container base (21) and an inner container wall (22) which are connected together so as to form a container area (23) which is open on one side. The inner container wall (22) comprises an upper edge section (221), and the outer container base (31) comprises a lower edge section (311), said upper edge section and lower edge section being designed in a complementary manner in order to engage into each other when stacking containers (1) are stacked one over the other such that the outer container base (31) of an upper stacking container (1) in the stack forms a cover for a stacking container (1) arranged therebelow, and a vacuum insulating element (5) is arranged between the inner container wall (22) and the outer container wall (32) and between the inner container base (21) and the outer container base (31).

1 . Stacking container for the temperature-controlled transport of food, comprising an outer container with an outer container bottom and an outer container wall, which are connected together so as to form a receiving space which is open on one side, and wherein the stacking container additionally comprises an inner container with an inner container bottom and an inner container wall which are connected together so as to form a container space which is open on one side, wherein the inner container wall comprises an upper rim section, and the outer container bottom comprises a lower rim section which are designed in a complementary fashion so as to engage into each other when stacking containers are stacked one over the other such that the outer container bottom of an overlying stacking container in the stack forms a lid for a stacking container arranged therebelow, and wherein a vacuum insulation element is arranged between the inner container wall and the outer container wall and between the inner container bottom and the outer container bottom. 
     
     
         2 . Stacking container according to  claim 1 , wherein the inner container wall at the upper rim section and the outer container bottom at the lower rim section each comprise an L-shaped stop. 
     
     
         3 . Stacking container according to  claim 2 , wherein the L-shaped stop at the upper rim section and the lower rim section each comprises a first profile section and a second profile section each having a minimum length of 0.5 cm. 
     
     
         4 . Stacking container according to  claim 1 , wherein the inner container wall comprises a projection completely encircling the upper rim section and having a size and shape such that, in the inserted state, the projection covers the outer container wall at least in sections. 
     
     
         5 . Stacking container according to  claim 4 , wherein the projection of the inner container is fixedly connected in an encircling fashion to the outer container wall. 
     
     
         6 . Stacking container according to  claim 4 , wherein the projection of the inner container and the outer container wall are made of a thermally joinable plastic material, and wherein the projection of the inner container is welded to the outer container wall. 
     
     
         7 . Stacking container according to  claim 4 , wherein the projection of the inner container is bonded to the outer container wall. 
     
     
         8 . Stacking container according to  claim 4 , wherein the projection of the inner container is detachably connected in an encircling fashion to the outer container wall. 
     
     
         9 . Stacking container according to  claim 1 , wherein the inner wall, starting from the inner bottom, is arranged in a vertically tapering fashion or in a conically diverging fashion. 
     
     
         10 . Stacking container according to  claim 1 , wherein the size of the inner container bottom surface is at least 70% of the size of the outer container bottom surface. 
     
     
         11 . Stacking container according to  claim 1 , wherein the vacuum insulation element is a single vacuum insulation panel, and wherein the vacuum insulation panel comprises at least one folding edge. 
     
     
         12 . Stacking container according to  claim 11 , wherein the vacuum insulation panel comprises four folding edges, and wherein said four folding edges, in the installed state, are each arranged along the outer periphery of the outer container bottom. 
     
     
         13 . Stacking container according to  claim 1 , wherein the outer container bottom has a size and shape so as to terminate in a completely encircling fashion the upper rim section.
