<P>PROBLEM TO BE SOLVED: To provide a lid material with a hot water dripping function which lid material prevents a user from mistaking a hot water dripping pull-tab for an unsealing pull-tab that is held upon unsealing the lid material temporarily, and has an outer peripheral shape offering a general-purpose function. <P>SOLUTION: The lid material 1 sealed on a container flange is a laminated material made by laminating a paper layer, a peeling layer, an adhesive resin layer, a gas barrier layer, and a sealant layer in this order on one surface of a base material layer. The lid material 1 has the unsealing pull-tab 3 which is formed on the outer peripheral edge of a lid material body to project outward, and the semielliptical hot water dripping pull-tab 4 having a plurality of inner hot water dripping holes, which hot water dripping pull-tab 4 is formed near the inside of the outer peripheral edge that is opposite to the unsealing pull-tab 3 in such a way that the arcuate front end of the semielliptical shape is located inside an area of the outer periphery that is sealed on the container flange. Each inner hot water dripping hole has a back half cut groove which is formed along the entire periphery of the dripping hole to extend in the direction of thickness of the laminated material from the sealant layer to cut into the peeling layer. The hot water dripping pull-tab 4 has a front half cut groove which is formed along the entire periphery of the pull-tab 4 to extend in the direction of thickness from the base material layer to cut into the peeling layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
