PROBLEM TO BE SOLVED: To enable effecting a heat seal between the sealing lid member and the edge of the mouth of a containter of synthetic resin securely, in a stabilized state, and without impairing the easy-peel property in the use of a sealing lid member in the form of a sheet having on one side a heat-seal layer for producing a heat seal with an easy-peel property. SOLUTION: The subject relates to a heat-seal head for effecting a heat seal between the edge of the mouth of a container of synthetic resin and a sealing lid member in the form of a sheet having on one side a heat-seal layer for effecting a heat seal with an easy-peel property. There are provided a heater block 2 with which a heater is connected and an elastic member 4 for heat sealing which, provided directly on the heater block or indirectly thereon with an interposition, presses the sealing lid member 13 against the edge of the mouth 15 of the container 14 and transmits the heat from the heater to the sealing lid member so as to effect a heat seal. |
