Description of the Related Art Supermarkets and convenience stores sell, for example, packed lunches and prepared foods in a so-called "packed form", and this pack is the packaging container referred to here. This packaging container generally comprises a container body for packing the contents and a lid for covering the contents from above in order to prevent the contents from being deformed. When attaching to the container body, it is classified into "outer fitting" and "inner fitting" depending on whether it is performed outside or inside.

[0003] In conventional packaging containers, the lid is generally fixed to the container body by "outside fitting". However, it is necessary to prevent the liquid in the contents from leaking. "Inner fitting" for reasons such as being able to secure rigidity when multiple
Packaging containers of the form are being reviewed.

[0004] As such a conventional inner-fitting type packaging container, for example, there is a "packaging container" proposed in Japanese Utility Model Publication No. 7-2427. As shown in FIGS. 7 and 8, this conventional packaging container has a structure in which a stepped shoulder is formed on the inner upper portion of the container body, and a lower peripheral edge of a lid is fitted into the stepped shoulder. , A lid engaging projection protruding inward at an appropriate interval above at least a part of the shoulder of the container body, and an inclined surface between which the knob of the lid abuts is recessed between the projections. A tab extending outwardly from the lower outside of at least a portion of the lid to form a knob that can contact the inclined surface. " As it is stopped, it can maintain a stable closed state, and can be opened simply by pulling the knob of the lid upward without performing an operation to deform the container main body. The deformation resistance of the lid is extremely low only on a part of the periphery, and the lid is in a stable closed state Lid opening is considered to be able to "be simple and easy to perform.

However, in this conventional packaging container, as shown in FIG. 8, the tip of the knob has a large projection above the outer peripheral edge (flange) of the container body. It is thought that such a problem occurs.

That is, in this type of packaging container in which the lid is fitted to the container body, the whole fitted with the contents is further wrapped with a wrap or a film. The wrap and the like prevent the lid from being disengaged and prevent the liquid juice from leaking out, or prevent foreign matter and moisture from entering from outside. The wrap or the like may be caught on the tip of the knob portion protruding in the state shown in FIG. Further, it goes without saying that handling of this packaging container becomes inconvenient if the tip of the knob is protruded without wrapping.

The inventors of the present invention have conducted various studies on how to avoid the above-mentioned problem with the wrap while utilizing the convenience of the knob portion. It was completed.

Each of the concave portions or convex portions 32 is formed at the same time when the synthetic resin sheet is molded and does not need to be so large, so that it can be formed very easily. You can do it.

When the concave portion or the convex portion 32 is formed on the knob portion 30 side, as shown in FIG. As shown by the imaginary line in FIG. 5, the finger can be hung on the outer end 31 of the knob portion 30 to easily lift it. . Similarly, when the concave or convex portion 32 is formed on the horizontal bottom surface 13a of the concave portion 13, as shown in FIG. 6, the knob portion 30 which remains flat comes into contact with the concave or convex portion 32 and rises. It becomes something.

Therefore, according to the packaging container of the third aspect, the same operation and function as those of the packaging container of the first or second aspect are exhibited, and furthermore, the operation of the knob portion 30 is further improved. It can be done easily.
