       8 . Container according to  claim 1 , wherein the peel tab, in the case of a closed container, covers over, starting from the withdrawal opening, more than one third, preferably more than two thirds and especially nine tenths up to the entire external surface of the lid part and/or base part. 
   
   
       9 . Container according to  claim 1 , wherein the withdrawal and/or venting opening is reversibly coverable, especially re-closable, by means of the peel tab. 
   
   
       10 . Container according to  claim 3 , wherein the peel tab has a deformation which is complementary to the withdrawal and/or venting opening and which is suitable for engaging in the withdrawal and/or venting opening, optionally snapping into place therein, when closing, especially re-closing, the container. 
   
   
       11 . Container according to  claim 1 , wherein the peel tab has a gripping portion, for example in the form of a folding-up or folding-back, and/or the peel tab and/or the gripping portion extends slightly beyond the peripheral margin of the container. 
   
   
       12 . Container according to  claim 11 , wherein the peel tab is fixed in the region between the withdrawal and/or venting opening and the gripping portion by means of adhesive bonding or sealing, especially pointwise sealing or pointwise adhesive bonding.

       15 . Container according to  claim 3 , wherein the peripheral margin is partly folded back, the folding-back optionally being extended and co-operating with, especially being joined to, the peel tab to form a channel. 
   
   
       16 . Container according to  claim 3 , wherein there is provided a pressure and/or volume equalisation arrangement, especially in the form of a membrane which is deformable and preferably capable of snapping back into place and/or in the form of an accordion-like arrangement. 
   
   
       17 . Container according to  claim 16 , wherein the pressure and/or volume equalisation arrangement, especially an accordion-like arrangement, is arranged inside the container body. 
   
   
       18 . Container according to  claim 1 , wherein the peel tab is of integral construction with the lid part. 
   
   
       19 . Container according to  claim 1 , wherein an end of the container body that is located opposite the lid part is closed by means of a fin seal.
