PURPOSE:To protect the opening from direct collision with objects at the time of diagonal fall of the container, by including a surface vertical to the diagonal line of the container in the upper end face of the opening of the container body, by including a surface corresponding and parallel to a surface vertical to the container diagonal line of the upper end in the peripheral edge of the detachable cap, and by including a sealant gasket between the surface and the upper end face with a surface corresponding to it. CONSTITUTION:The container's opening with a detachable cap has the upper end face 6 of top 5 of the opening of the container body corresponding to the surface 13 of the peripheral edge 12 of cap 11, and bath surfaces 6 and 13 include surfaces 8 and 14 vertical and corresponding to the diagonal line 7 of the container and include a gasket 21. Therefore, in the diagonal fall of container along the diagonal line 7 with the container's top 2 down, the container collides with objects on the outside surface 28 of the peripheral edge 12 of the container's cap, and the surfaces 8 and 14 come into contact. The surface 28 is vertical to the diagonal line 7, impact less concentrates upon collision. The gasket 21 is protected by the parallel contact of the surfaces 8 and 14 vertical to the diagonal line 7 and does not undergo damage spoils sealing property. |
