         16 . A container, comprising:
 a body provided with a ring determining an opening;   a foil adhered to the ring and closing the opening; and   a lid covering the foil and connected to the ring,   wherein the ring and the lid are resiliently connected and the foil is adhered to the ring in the resilient connection between the ring and the lid.   
     
     
         17 . The container according to  claim 16 , wherein the resilient connection has a contact area which is at an angle of 45-100°, more preferably 45-90°, more preferably 75-90° with the horizontal plane defined by the ring. 
     
     
         18 . The container according to  claim 16 , wherein the resilient connection is formed by a lid part and a ring part of which parts at least one part is resilient. 
     
     
         19 . The container according to  claim 18 , wherein the lid part and the ring part are both resilient. 
     
     
         20 . The container according to  claim 18 , wherein the resilient part is resiliently deformed to 0.2% of the yield point. 
     
     
         21 . The container according to  claim 16 , wherein in the resilient connection the surface pressure is within the range of 600-1300N/cm 2 , preferably 700-1200N/cm 2 . 
     
     
         22 . The container according to  claim 16 , wherein the lid resides within the ring opening. 
     
     
         23 . The container according to  claim 16 , wherein the lid closes over the ring opening. 
     
     
         24 . A set comprising a ring, a foil adhered to the ring and closing the opening, and a lid covering the foil and connected to the ring, wherein the ring and the lid are resiliently connected and the foil is adhered to the ring in the resilient connection between the ring and the lid. 
     
     
         25 . A method for producing a set comprising a ring, a foil adhered to the ring and closing the opening, and a lid covering the foil and connected to the ring, wherein the ring and the lid are resiliently connected and the foil is adhered to the ring in the resilient connection between the ring and the lid, said method comprising the steps of:
 i) forming a preset by resiliently connecting the foil between the ring and the lid; and   ii) subjecting the preset to a heat treatment for adhering the foil to the ring.   
     
     
         26 . The method according to  claim 25 , wherein the foil is mounted on the ring. 
     
     
         27 . The method according to  claim 25 , wherein the foil is mounted on the lid. 
     
     
         28 . The method according to  claim 26 , wherein the foil is mounted using clamping force and/or magnetic force. 
     
     
         29 . The method according to  claim 25 , wherein the heat treatment is carried out in an oven. 
     
     
         30 . A preset formed by resiliently connecting the foil between the ring and the lid according to step i) of  claim 25 .
