When the lid is fastened to the neck part of the bottle, the annular protruding part is positioned inside the neck part, where on the outer side face of the annular protruding part opposing to the inner side face of the neck part is formed a groove. The lid further includes a seal ring to be installed in the groove.SELECTED DRAWING: Figure 3 |
