化と作業能率の低下を招来していた。However, in the above-described conventional packaging container, the depth from the bottom surface of the concave portion to the upper surface of the peripheral wall of the container body is set to the depth at which almost the entire storage article, for example, a sandwich is stored. With this configuration, the sandwich can be prevented from falling down during the storage operation by contact with the inner surface of the peripheral wall, but when the sandwich stored in the recess of the container body is taken out, the sandwich is stored with the inner surface of the high peripheral wall. Since the finger has to be inserted into a narrow space between the sandwich and the sandwich, it takes time to take out the sandwich, and it is easy for the sandwich to lose its shape. Further, when the depth from the bottom surface of the concave portion of the container body to the upper surface of the peripheral wall is configured so that the uppermost half of the sandwich protrudes upward, when the sandwich housed in the concave portion of the container body is taken out, the sandwich is removed. Since the sandwich can be picked up from the lateral direction, the sandwich can be quickly and easily taken out with little deformation, but since the depth of the concave portion of the container main body is smaller than the height of the sandwich, the concave portion is formed. As a result, the sandwich housed in the container easily falls down, and as a result, the sandwich must be kept in a predetermined position until the lid is attached to the container body in the sandwich packaging process, which complicates the packaging operation and increases the work efficiency. Had been reduced.
