OPENING-CLOSING LID, CONTAINER EQUIPPED WITH THE LID, DEVICE FOR SEALING UP CONTAINER WITH THE LID AND PROCESSING METHOD FOR CONTAINER HAVING THE LID

摘要

PROBLEM TO BE SOLVED: To smoothly drip water. SOLUTION: The opening-closing lid comprises a heat-sealing layer composed of a uniaxially stretched synthetic resin film formed of a uniaxially stretched polyethylene(PE) film and an ethylene-vinylacetate copolymer (EVA) provided at the underside of the uniaxially stretched synthetic resin film, an adhesive layer formed of a urethane resin provided at the upside of the uniaxially stretched PE film and a biaxially stretched synthetic resin film formed of a biaxially stretched polyester (PET) film provided at the upside of the adhesive layer. A tab 13 for partial opening is provided at the end 10a on one side of opposite paired ends 10a and 10c of the opening-closing lid 10 and a tab 14 for opening the lid is provided at the end 10a on the other side. The tab 13 for partial opening is positioned, intersecting approximately at a right angle the diagonal line L connecting both ends 10a and 10c, and projected in the direction of stretching of the uniaxially stretched synthetic resin film, and the tab 14 for opening the lid is projected in the direction along the diagonal line L.
