Description

[Detailed description of the invention] [Industrial application field] This invention is a packaging container with a lid, mainly for storing food, which is formed by leaving a non-bulging part in a part of the fitting bulging part of the lid. It is related to.

[Prior Art] A conventional packaging container with a lid for foods, etc. includes a container body having a flange on the outside of the opening periphery at the top end;
A packaging container with a lid is known, which includes a lid that fits into the main body fitting part through a fitting bulge and has a flange corresponding to the flange.

[Problems to be solved by the invention] However, in the conventional techniques as described above, it is not easy to attach and detach the lid and the container body.
In particular, when the flange of the container body and the flange of the lid are temporarily bonded, it is difficult to remove the lid, and the container is likely to be damaged when the lid is removed. When cooking the food inside in a microwave oven, in order to prevent the container from bursting, etc., and to ensure proper cooking by evaporating the appropriate amount of water, either make a hole in the container or remove the lid and then re-open it. They were forced to do work such as fitting properly.

The present invention was made with the aim of improving these drawbacks of conventionally known packaging containers with lids.

[Means for Solving the Problems] This invention consists of a container body having a flange outside the opening periphery at the upper end, and a fitting bulge that fits into the body opening and corresponds to the flange. In a packaging container with a lid, the packaging container is composed of a lid body having a brim portion,
The fitting bulge 3 of the lid body 2 is formed by leaving a non-bulging part 4 in a part, which is a technical measure to solve the above-mentioned problems of the prior art.

[Example] Next, a typical example of this invention will be described based on the drawings.

The container main body 1 has a flange 1a on the outside of the opening periphery at the upper end, and the lid 2 fits into the container main opening through a fitting bulge 3, and the flange 1a
It has a flange portion 2a corresponding to the flange portion 2a.

The fitting bulge 3 of the lid body 2 is formed with a non-bulge 4 remaining in a part. In this example, the bulge 3 of the lid body 2
is formed so as to become gradually shallower toward the non-bulging portion 4, which is preferable because it is easier to remove. However, it is not necessarily limited.

It should be noted that if a bulging portion 6 is provided at the opening peripheral portion of the container main body corresponding to the non-bulging portion as shown in the drawing, internal gas will be easily discharged when used in a microwave oven.

Furthermore, if the flange 1a of the container body and the flange 2a of the lid are removably adhered, for example, by easy peel, airtightness can be maintained during distribution and storage.

Furthermore, it is desirable to form a peeling tab 5 at the outer end of the non-bulging portion 4 in order to facilitate removal of the lid.

The container is desirably made of a material that can withstand cooking of food in a microwave oven, such as polypropylene or polyester.

[Effect of the invention] As described above, the fitting bulge 3 of the lid body 2 is formed with the non-bulging part 4 left in a part, and has the non-fitting part, so this invention is completely The lid body and the container body can be attached and detached easily and smoothly compared to a case where the non-bulging portion 4 is not formed.

Even if the food inside the container is cooked with the lid closed in a microwave oven, etc., the air, water vapor, etc. that expand inside the container will escape from between the non-fitting part (non-bulging part) and the flange of the container body. Since it can be discharged to the outside of the container, it is possible to achieve a good cooking condition without causing the container to burst, and by evaporating a suitable amount of water, there is no need to make holes in the container or remove the lid. Yes, it is convenient.

Furthermore, even if the flange of the container body is temporarily attached to the flange of the lid, the lid can be easily removed from the container body from the non-bulging part, which is the non-fitting part. The container can be reattached and used to preserve the contents without causing damage, and even when cooking in a microwave, only the brim of the non-expanded part of the lid can be attached to the container. If the container is peeled off, the water vapor expanded inside the container will be discharged to the outside of the container through the gap between the non-expanded brim and the container body, so there is no need to make a hole in the container or remove the entire lid. It's simple.
