Container with a safety seal

Abstract

A container, in particular a plastic container, preferably in the form of a pail, having a lid for closing the container. The lid having a receiving area in which, when the container is in the closed state, the container lip limiting the container opening engages and is held, mutually interacting catch members and sealing surfaces being provided in the receiving area of the lid and on the lip of the container opening. The catch members being configured such that when the container is in the closed state, the sealing surfaces are pressed together reliably to form seals, and, in particular, can only be released by destroying the lid and/or the rim.

1 . A container, in particular a plastic container, preferably in the form of a pail, having a lid for closing the container, said lid having a receiving area in which, when said container is in the closed state, the container lip limiting the container opening engages and is held, wherein mutually interacting latch-detent hook members and sealing surfaces are provided in said receiving area of said lid and on said lip of said container opening, said catch members being configured such that when said container is in the closed state, said sealing surfaces are pressed together reliably to form seals, and, in particular, can only be released by destroying said lid and/or the rim.  
   
   
       2 . The container as claimed in  claim 1 , wherein said receiving area of said lid and said lip of said container opening are engineered such that closure of said container with said lid is effected essentially by a translational movement or, in particular, by pushing or clipping said lid onto said container from above.  
   
   
       3 . The container as claimed in  claim 1 , wherein at least two, preferably three or more latch-detent hook member pairs are provided, at least one of said latch-detent hook member pair preferably being engineered such that the catch is released by way of a different, in particular an opposing movement to that required to disengage the other of said latch-detent hook member pairs, so that in order to release the catch mechanism comprising differently acting said latch-detent hook member pairs, at least part of said lid's receiving area or of said lip of said container opening must be moved in different directions, especially opposite directions.  
   
   
       4 . A container according as claimed in  claim 1 , said sealing surfaces are provided separately from said latch-detent hook members and/or on the catch members.  
   
   
       5 . A container as claimed in  claim 1 , wherein at least one, preferably several of said seals are provided in said receiving area and/or on said lip of said container opening, said seals preferably being in the form, in particular, of inserted or injected gaskets.  
   
   
       6 . A container as claimed in  claim 1 , the wherein said receiving area of said lid and/or said lip of said container opening and further comprises a predetermined partition location for detachment of a part of said receiving area and/or of said lip, in particular of that part that has the differently functioning said latch-detent hook member pair(s), so that only identically functioning said latch-detent hook member pairs remain, in order to permit openings of said container closed with said lid.  
   
   
       7 . A container as claimed in  claim 1 , wherein the cross-section of said receiving area is essentially U-shaped and is open at the bottom, said lip of said container opening being at least partially, in a first section, straight in said cross-section and being defined between two legs of said U-shaped receiving area, and, further comprising detent hooks, latches and/or engagement grooves that interlock on closure being provided on an inner side of one of said leg and on the corresponding side of the first section of said lip, while on the inside of the other of said leg and on the corresponding side of said first section of said lip of said container opening, said sealing surfaces are provided.  
   
   
       8 . The container as claimed in  claim 7 , wherein at least two of said detent hooks are provided on the inside of said outer leg of said receiving area, and at least one of said detent hook on the outside of said outer leg.  
   
   
       9 . The container as claimed in  claim 7 , wherein said lip of said container opening is at least partially—in particular in a second section extending over a portion of said lip insertable into the said receiving area—double-walled, said outer leg of said receiving area engaging at least partially in the space between the two walls of said lip.  
   
   
       10 . The container as claimed in  claim 9 , further comprising an outer element in said second section of the double-walled lip has an undercut or a latch-detent hook member, which interacts with said detent hooks on the outside of said outer leg of said receiving area, and, in particular, forms said latch-detent hook member pair which, compared with said latch-detent hook members on the inside of said outer leg of said receiving area and with said latch-detent hook members on the outside of said element of the first section of the double-walled lip of said container opening, requires a different, in particular an opposing, opening movement in order to release said catch.  
   
   
       11 . A container as claimed in  claim 8 , characterized in that said outer leg of said receiving area of said lid has a predetermined partition location in the form of a film hinge for the purpose of parting with a cutting tool, in particular a knife, said predetermined partition location preferably being positioned such that the lower segment of said outer leg of said receiving area, which segment contains the two, in particular differently functioning, said latch-detent hook member pairs, is detached and remains, in particular, in said double-walled portion of said lip of said container opening.  
   
   
       12 . A container as claimed in  claim 7 , wherein the connecting area of said legs of said receiving area, further comprises a gasket, in particular an O-ring, is provided, which, when said container is in the closed state, is pressed into said receiving area by the upper end of said lip of said container opening.  
   
   
       13 . A container as claimed in  claim 1 , wherein said catch members are arranged as circumferential hooks or latches on said lip of said container opening and/or on said receiving area.  
   
   
       14 . A container as claimed in  claim 1 , wherein said container with said lid is securely and tightly closed at inside pressures of up to 1 bar, particularly up to 0.8 bar in the case of liquid and pasty substances in particular, and, in particular, satisfied the UN licensing conditions for the transport of hazardous liquid substances.
