Packaging containers

Abstract

This product consists of a container body formed by press-molding cardboard and equipped with a flange, and a film-like lid material that is attached to the upper surface of the flange so as to cover the top of the container body. When in use, it can be used with food or the like stored in the container body. The outer edge of the flange is equipped with a rim roll, and the upper end of the rim roll is formed so as not to exceed the height of the top surface of the flange. In addition, numerous wrinkles are formed on the side wall and flange. The wrinkles formed on the flange are flatter than the wrinkles formed on the side wall. As a result, the entire top surface of the flange is flat, resulting in excellent top sealing performance. Furthermore, since the rim roll is not located on the outer extension of the mounting surface of the lid material, the lid material can be easily attached, improving the yield.
