ることができなかった。However, a method of separately forming the lid and the spoon and then bonding or fitting the lid and the spoon becomes a factor of high cost due to the complicated manufacturing process, and also causes a problem in filling the contents. And during distribution, the spoon could fall off the lid. After integrally molding the peripheral wall and the spoon, the method of bonding or fitting the top surface member to the upper edge of the peripheral wall is as follows:
Since the number of manufacturing steps is large and complicated, this method also causes an increase in cost, and in the manufacturing steps, warpage may easily occur since the peripheral wall has no top surface. Also,
In the method of integrally molding the lid and the spoon with the spoon housed in the inner surface of the lid, there is little gap between the spoon and the top surface. It was not possible to form a spoon having a shape that would perform various functions.
