PROBLEM TO BE SOLVED: To provide a push-pull opening/closing lid which prevents a tongue from being bitten between a lower edge of a pouring opening of a tip and a tip of an inner cylindrical part and being caught therebetween, ensures the predetermined pouring flow rate, and prevents the reverse flow of the food. SOLUTION: In the push-pull opening/closing lid provided with the tip 20 comprising a skirt part 5 to be tightened to a container month part, an annular wall 4 for tightening an outer lid smaller in diameter than the skirt part 5, a top pate part 6 above the annular wall 4, an outer cylindrical part 2 provided above the top plate part 6, an inner cylindrical part 3 provided concentric with the outer cylindrical part 2 and smaller in diameter than the inside diameter of the outer cylindrical part, an opening part 9 provided between the outer cylindrical part 2 and the inner cylindrical part 3, a cap body 1 comprising a bridge 7 to connect the outer cylindrical part to the inner cylindrical part, a cylindrical part 24 vertically slidable along the outer cylindrical part 3, a top part 21 connected to an upper portion of the cylindrical part, and the pouring opening 22 in the center of the top part to be covered in a liquid-tight manner on an upper portion of the inner cylindrical part at the lowered position, a rib 27 extending horizontally across the opening part is formed in the pouring opening 22 of the tip 20, and a band 29 for sealing the inner cylindrical part extending downward in a cylinder is formed on the inner end part of the top part. |
