Chemical container for high-pure chemicals

Abstract

Chemical container made of plastics, comprising a body having side walls being arranged perpendicularly with respect to each other and a base, whereby at least one mold separation seam or accumulation of material due to production, respectively, is arranged in the edge being formed between two side walls and at least one mold separation seam or a combination of material due to production, respectively, is arranged diagonally over the base.

1 . Chemical container made of plastics, comprising: 
 a body ( 1 ) having side walls ( 1   a,    1   b,    1   c,    1   d ) being arranged perpendicularly with respect to each other and a base ( 4 ), whereby    at least one mold separation seam ( 3 ) or accumulation of material due to production, respectively, is arranged in the edge being formed between two side walls ( 1   a,    1   b ) and    at least one mold separation seam  7  or a combination of material due to production, respectively, is arranged diagonally over the base  4 .    
   
   
       2 . Chemical container according to  claim 1 , the chemical container being made of high-dense polyethylene (PD-HD), preferably of the type Lupolen 6021D or Lupolen 5021D.  
   
   
       3 . Chemical container according to one of the preceding claims, whereby two side walls ( 1   a,    1   b ) of the chemical container being each formed in their top section such that a partial area ( 2   a,    2   b ) of the side wall ( 1   a,    1   b ) is oriented obliquely backwards out of the plane of the respective side wall ( 1   a,    1   b ) and the partial areas ( 2   a,    2   b ) together form an area  5  being oriented perpendicularly with respect to the base  4  and parallel with respect to one diagonal of the base  4 .  
   
   
       4 . Chemical container according to  claim 3 , whereby a handle ( 6 ) is attached at the top and at the bottom to the area ( 5 ) to the chemical container, being oriented substantially symmetrical with respect to the edges, being formed between two side walls ( 1   a,    1   b ), respectively, of the chemical container and being arranged in front of the area ( 5 ) being formed by the partial areas ( 2   a,    2   b ) of the side walls being obliquely arranged.  
   
   
       5 . Chemical container according to one of the preceding claims, whereby the handle ( 6 ) is arranged such that it does not protrude in a direction parallel with respect to the cross section area formed by the base ( 4 ) over the base ( 4 ).  
   
   
       6 . Chemical container according to one of the preceding claims, whereby the chemical container comprises a handle ( 6 ) being formed in one piece with the chemical container.  
   
   
       7 . Use of the chemical container according to one of the preceding claims for storing and for transport of the chemicals.  
   
   
       8 . Use according to  claim 7 , whereby the chemicals are selected under: hydrofluoric acid (HF), hydrochloric acid, sulfuric acid, hydrogen peroxide, ammonium fluoride solutions, etching mixtures of HF and ammonia solution, ammonia solution, ethanoic acid, 2-propyl alcohol phosphoric acid, and nitric acid.
