PURPOSE: To ensure sealing of a liquid stored in a bottle even during the transportation thereof by a method wherein a seal element is formed integrally to an inner shell or outer shell of a closing cap and disposed in a ring-shaped receiving part protruding toward the outer shell or the inner shell. CONSTITUTION: Both the inner and outer shells 8, 9 of a closing cap 2 are formed into a cup-like shape, and a seal element 4 is disposed in a ring-shaped receiving part 10 provided on the side of the shell 8 opposed to the shell 9. The element 4 is received in the cap 2 in such a condition that loads are applied on the element in the radial and axial directions. The loads, in the radial and axial directions, are designed such that a first through hole 3 and a second through hole 21 are automatically closed when an injection spike 19 and a cannula 20 are removed from the holes 3, 21 respectively. Thus, if a bottle 1 is suspended and even if the spike 19 and cannula 20 are removed during the transportation of liquid, the liquid in the bottle can be prevented from flowing out. |
