As described in Japanese Patent No. 4794, a structure in which the container body and the lid are not connected,
As described in Japanese Patent Publication No. 56-56, a structure in which a container body and a lid are connected by a hinge portion has been proposed. These containers were closed with a lid after storing the article in the container body, and when fixing both, stabbing with a rubber band or a stapler was common. However, such a fixing method has drawbacks from the viewpoints of workability and safety. Therefore, as described in Japanese Utility Model Publication No. 48-43050, the container body can be covered without using a stapler. There has been proposed a container having a structure that can be closed and sealed. However, this real public 48-430
No. 50 requires sealing with an adhesive tape, and there is still a problem from the viewpoint of workability and hygiene.

た。Thereafter, as described in, for example, Japanese Utility Model Publication No. 53-5560 and Japanese Utility Model Publication No. 55-47148, the lid body is fitted to the container body without the need for sticking with a stapler or sealing with an adhesive tape. A container having a structure capable of being combined and sealed has been proposed and put into practical use. However, in the container having the structure described in Japanese Utility Model Publication No. 53-5560, it is not easy for a user to open the lid when taking out the contents, and in addition, the container body and the lid are made of a thin synthetic resin. Since it is a product molded from a sheet, it is not possible to hold the container body and lid with a strong force, and therefore it is difficult to apply a force to open the lid, which makes it extremely difficult to open the lid. There is a drawback that. Further, the container described in Japanese Utility Model Publication No. 55-47148 has a drawback in that, when an article containing a liquid component is stored in the container and the lid is closed and the storage container is rotated, the liquid component leaks out of the container. There has been a demand for a hermetically sealed packaging container which has solved these disadvantages at once.

The flange portion of the lid, together with the lid horizontal step portion 14, exerts a repulsive force against a twisting stress to the lid, and functions so as not to damage the lid. In the lid extending portion 17, a lid protrusion or a groove is formed at a position slightly apart from the uppermost portion of the lid vertical portion 15 along the uppermost portion of the curved portion. FIG.
Then, the example in which the lid groove 18 is formed is shown. The lid groove 18 fits with the container protrusion 8 and prevents the liquid component of the article housed in the article housing portion from leaking out of the container together with the fitting portion of the lid vertical portion 15. Perform a function.
Therefore, it is necessary that the container protrusion 8 formed on the container extension 7 and the lid groove 18 formed on the lid extension 17 be in line contact or surface contact over the entire circumference. is there. When a container groove is formed in the container extending portion 7, a lid protrusion that fits in the groove is formed in the lid extending portion 17.

ない。INDUSTRIAL APPLICABILITY The inner fitting and sealing type packaging container according to the present invention has the following particularly advantageous effects and its industrial utility value is extremely large. 1. Since the inner fitting hermetically-sealed packaging container according to the present invention can fix both by fitting the peripheral wall portion of the lid to the peripheral wall portion of the container main body opening, there is no need for sticking with a stapler and sealing with an adhesive tape. It has excellent workability, safety, and hygiene. 2. The inner fitting hermetically-sealed packaging container according to the present invention includes contact between the container vertical portion 5 and the lid curved portion 15 over the entire circumference, the container protrusion 8 of the container extension portion 7, and the lid extension portion 17. By making contact with the lid strip groove 18 over the entire circumference, it is possible to completely prevent the liquid component of the article stored in the article storage portion from leaking out of the container. 3. The inner fitting hermetically-sealed packaging container according to the present invention is formed with a fitting part (a container horizontal step, a container vertical part, a container extending part, a container ridge, etc.) at a container opening of a container body, and The lid is also formed with fitting portions (horizontal lid step, lid curved portion, lid extending portion, lid ridge, etc.) that are mutually fitted with the fitting portion of the container opening. Therefore, this portion exerts a repulsive force against the repulsive force against the twisting stress on the packaging container and is not damaged.
