Description

The present invention relates to a packaging container.

For example, a packaging container is used for packaging foods such as lunch boxes and prepared foods. Such packaging containers are often formed by sheet molding. An example of such a sheet-molded packaging container is disclosed in Japanese Patent Application Laid-Open No. 2010-184742 (Patent Document 1). The packaging container (container with lid 5) of Patent Document 1 includes a main body engaging portion (recessed groove 24) provided in the main body skirt portion (outer peripheral wall 15) of the container main body (container main body 1) and a lid body (cover). The lid engaging portion (convex groove 32) provided in the lid skirt portion (outer fitting portion 15) of the body 3) is engaged with the lid, and the closed state is appropriately maintained. Further, at the time of opening the lid, the grip portion (tongue piece 37) provided on the lid body is picked to release the engagement between the main body engaging portion and the lid engaging portion, and the lid body is removed from the container main body. Can be done.

However, if some external force is applied to the knob from below in the closed state, the lid may be unintentionally removed from the container body. On the other hand, if the main body engaging portion and the lid engaging portion are formed so that the fitting force is increased so as to prevent the lid from being unintentionally disengaged, it becomes difficult to remove the lid even during a normal opening operation.

The protruding portion 58 of the lid skirt portion 54 covers the notch 38 of the main body skirt portion 34 from the outside in the closed state. As a result, the notch 38 is provided in the main body skirt portion 34 in order to promote the bending of the main body flange portion 33 and the main body skirt portion 34, and the deterioration of the design in the closed state is avoided.

To remove the lid 5 from the container body 3, for example, as shown in FIG. 7, while pinching the gripping portion 56 from above and below with two fingers F (for example, the thumb and the index finger), the upper finger F (for example, the thumb) Place the fingertip on the wide portion 53C of the lid flange portion 53. At this time, since the boundary line between the lid peripheral wall portion 52 and the lid flange portion 53 in the wide portion 53C has an inwardly convex arcuate shape, the shape of the fingertip can be easily fitted and the fingertip can be widened. Easy to put on 53C. Further, since a plurality of fine protrusions 53D are formed on the wide portion 53C, it is possible to prevent the wide portion 53C from slipping while the fingertip is placed on the wide portion 53C.

In this state, as shown in the upper part of FIG. 8, the gripped portion 56 picked by the two fingers F is pulled up diagonally upward with the fingertip of the finger F placed on the wide portion 53C as a fulcrum. At this time, a raised portion 56C is formed on the picking main body portion 56B of the picking portion 56, and a recess is formed on the lower surface side. It can be easily pulled up. By this pulling operation, the lid skirt portion 54 is deformed into a hairpin-like cross section while the main body flange portion 33 and the lid flange portion 53 are kept in close contact with each other, and the upward extending portion 56A constituting the knob portion 56 is formed. The picking main body portion 56B is deformed into a substantially coplanar shape. Further, in the container body 3, the portion between the two bending deformation promoting portions 37 (notch portions 38) located on both sides of the knob portion 56 is bent and deformed so as to be inclined downward. Then, the linear protrusions constituting the lid engaging portion 55 are separated upward from the concave groove portion constituting the main body engaging portion 35.

Once the lid engaging portion 55 is disengaged from the main body engaging portion 35, as shown in the lower part of FIG. 8, the lid engaging portion 55 is placed on the inclined portion (inclined wall portion) of the main body skirt portion 34 from above. Even if the lid F is engaged and the finger F is released, the lid engaging portion 55 and the main body engaging portion 35 do not re-engage. After that, if the main body portion 56B and the raised portion 56C are picked up with the finger F and further pulled up, the other lid body engaging portions 55 are sequentially disengaged from the main body engaging portion 35, and finally the lid body is removed from the container main body 3. 5 can be removed. In this way, the lid opening operation can be easily performed.
