Thereby, even when there is not sufficient space for gripping the packaging container between the pillow packaging body and the packaging container packaged therein, the packaging container is operated via the knob body. Thus, the packaging container can be easily taken out from the pillow package.

  Further, the knob body having an inverted U-shaped cross section also functions as a buffer portion that absorbs the force acting from the side of the packaging container. For this reason, it is difficult for impact from the outside to be transmitted to the food contained in the packaging container, and the food can be more reliably protected.

  The packaging container according to claim 2 is characterized in that, in the invention according to claim 1, the top of the knob body is provided with recesses facing each other across the inner area of the container body. To do.

  Generally, when packaging foods that are easily deformed, such as cakes, crepes, and waffles, the packaging container may be formed in a deep shape that covers the entire food. In such a case, since most of the food contained in the packaging container is covered with the packaging container, it is difficult to grab the food by hand and remove it from the packaging container. It was. For this reason, the packaging container is turned upside down to remove the stored food. However, according to the said structure, it becomes easy to grasp a foodstuff through the recessed part provided in the top part of a knob body, and it is possible to take out the foodstuff accommodated in the container for packaging more easily.

  A packaging container according to a third aspect is the invention according to the first or second aspect, wherein the outer wall of the knob body having an inverted U-shaped cross section has a finger slip relative to the outer wall. Slip suppression means is provided for suppressing the slip.
