PURPOSE:To provide a safe and hygienic cap seal with the top cover which prevents bacteria, dusts, water, etc., from penetrating and can be opened by one-touch and completely removed from the bottle head after opening. CONSTITUTION:In a cap seal with the top cover thermocontracting and fitting on a bottle head 3, the upper end of a tear-tape 13 bent at the upper end is stuck to the periphery of a circular disk-form top face 8 and the top face 8 is connected to the under-side of the folded part 14a at the upper edge of a cylindrical thermocontracting film 14 bent inward at the upper edge and the lower end of tear-tape 13 is extended down from the lower part of the inside of the thermocontracting film 14. And vertical recessed grooves 15 are formed on the thermocontracting film 14 along both side edges of the taer-tape 13. In this way, a circular recessed groove 16 is formed at the folded part 14a of the upper edge surrounding the top face 8, subsequently to the upper part of recessed grooves 15. |
