Field of the Invention The present invention relates to a packaging container comprising a container main body and a lid fitted to a flange portion thereof, and more particularly to a packaging container capable of easily releasing the lid from the container main body. The present invention relates to a devised packaging container.

[0002]

2. Description of the Related Art For example, a packaging container for storing a lunch box or a prepared dish often comprises a container body having a storage portion and a lid fitted to the container body. In general, the container body and the lid are integrally formed from a relatively thin synthetic resin sheet. In this type of packaging container, the container body and the flange portion of the lid are formed with irregularities that are fitted to each other, and the two are externally or internally fitted to each other to seal food and the like. It tries to make the property good.

In such a packaging container formed of a synthetic resin sheet, it is relatively easy to fit the lid to the container body containing the food or the like. Then, since both are formed by a relatively thin synthetic resin sheet, it is often difficult. In particular, when the lid is made of a transparent material so that the contents can be seen, it is more difficult to remove the lid from the container body because the boundary between the two is difficult to see. It has become.

Therefore, in a conventional packaging container, for example, in Japanese Utility Model Laid-Open Publication No. 63-123461 or Japanese Utility Model Laid-Open Publication No. 63-123462, "a flange portion of a container body is exposed at a flange portion of a lid. Or a hole in the flange of the lid where the protruding portion on the container body side protrudes), and then the container body from the hole on the flange side It has been proposed to press the side flange or protrusion with a finger.
That is, by pressing the flange or the protruding portion on the container body side with a finger through the hole of the lid body, a force can be applied to the container body side separately from the lid body, and the fitting between the two can be performed. This makes it easy to cancel the combination.

However, if a "hole" is formed in the lid so that a finger can be inserted, the flange of the container body and the flange of the lid are rarely in close contact with each other. It is easy for dirt and the like to enter into the inside, and conversely, it is also a part from which moisture and water vapor are emitted, so that the broth or the like of the contents leaks out and the drying of the contents tends to be promoted.

Therefore, the inventor of the present invention has an advantage that in this type of packaging container, a force can be applied to the container body side separately from the lid so that the fitting between the two can be easily released. The present invention has been completed as a result of various studies on how to make a packaging container suitable for containing foods and the like while making good use of the above.
