<p>PURPOSE:To prevent the spillage of a liquid effectively attributed to cracking while carrying out a mars production at a low cost. CONSTITUTION:The infusion container 6 for a medicine is provided with a container body 6 for storing an infusion and a rubber cock 2 made of a rubber- like elastic material to close an opening of the container body 6. A mark 4 for pricking with a needle is formed on the top surface of the rubber cock 2 to indicate a position of pricking with the needle 1. A protruding thread 7 of a closed loop is formed on a surface contacting infusion in the bottom surface of the rubber cock 2 at a postion corresponding to the needle pricking mark 4. In this manner, as the mark 4 is made with the protruding thread 7 of the closed loop formed on the bottom surface thereof, cracking is prevented effectively at a part where a needle 1 is inserted with an aid of the protruding thread 7. This allows the forming of the protruding thread 7 using a small amount of the rubber-like elastic material thereby preventing the cracking effectively with limited material used.</p> |
