[0049] The main body groove 206 is provided so as to surround the main body outer side surface portion 208. The main body groove 206 is provided on the inside of the main body flange portion 204. The main body groove 206 is located between the main body flange portion 204 and the main body frame portion 210. The main body groove 206 is connected to the main body outer side surface portion 208.

[0050] As shown in Fig. 4, the main body groove 206 is provided at a position lower than the main body flange 204. The width of the main body groove 206 is equal to or narrower than the width of the main body flange 204. By providing the main body groove 206 in this way, the main body flange 204 can be easily molded and the strength of the main body flange 204 can be increased. Note that the main body groove 206 does not have to be provided in the container body 20.

[0051] The body outer surface portion 208 is provided to surround the body frame portion 210. The body outer surface portion 208 is provided inside the body groove portion 206. The body outer surface portion 208 is located between the body frame portion 210 and the body groove portion 206. The body outer surface portion 208 is connected to the body frame portion 210 and the body groove portion 206. The body outer surface portion 208 extends from the body frame portion 210 toward the body groove 206.

[0052] The main body outer side surface portion 208 has a side surface protrusion 208C.

[0053] As shown in FIG. 4, the side protrusions 208C protrude inward. The side protrusions 208C are provided between the legs 214L. For example, as shown in FIG. 3, when the container body 20 is rectangular, the side protrusions 208C are provided on the main body outer side surface portions 208 corresponding to each side of the container body 20. Furthermore, the side protrusions 208C are disposed at the middle of the main body outer side surface portions 208 corresponding to each side of the container body 20. In this way, by providing the side protrusions 208C, the strength of the main body outer side surface portion 208, the main body inner side surface portion 212, and the main body frame portion 210 is increased. Note that the main body outer side surface portion 208 does not necessarily have to have the side protrusions 208C.

[0054] The main body frame 210 is provided so as to surround the main body inner side surface 212. The main body frame 210 is provided inside the main body outer side surface 208. The main body frame 210 is located between the main body groove 206 and the main body inner side surface 212. The main body frame 210 is connected to the main body groove 206 and the main body inner side surface 212.

[0055] The main body frame 210 is provided at the highest position on the container body 20. The main body frame 210 is provided at a position higher than the main body flange 204. Specifically, as shown in Fig. 4, the height 210H of the main body frame 210 from the lowest position on the container body 20 is higher than the height 204H of the main body flange 204 from the lowest position on the container body 20. This allows the main body frame 210 to emphasize the area in which food or the like is stored.

[0056] Width 210W of main body frame 210 is narrower than width 204W of main body flange 204. Specifically, as shown in Fig. 4, width 210W of main body frame 210 in the horizontal direction is narrower than width 204W of main body flange 204. By providing main body frame 210 in a position that is higher and more inward than main body flange 204 in this way, food or the like stored therein is pushed up above the height of main body flange 204, making it easier to see the food in three dimensions and making it less likely for the food or the like to shift out of position. Furthermore, by providing main body frame 210 in this way, the depth of main body bottom 214 is increased, allowing more food or the like to be stored therein.

[0057] The main body inner side surface portion 212 is provided so as to surround the main body bottom portion 214. The main body inner side surface portion 212 is provided inside the main body frame portion 210. The main body inner side surface portion 212 is located between the main body frame portion 210 and the main body bottom portion 214. The main body inner side surface portion 212 is connected to the main body frame portion 210 and the main body bottom portion 214.

[0058] The main body inner side surface portion 212 extends from the main body frame portion 210 toward the main body bottom portion 214. The main body inner side surface portion 212 is provided so as to connect the main body frame portion 210 and the main body bottom portion 214. By providing the main body inner side surface portion 212 in this way, the inclination of the main body inner side surface portion 212 becomes greater than when the main body inner side surface portion 212 is provided so as to connect the main body flange portion 204 and the main body bottom portion 214 in the container body 20. The greater inclination of the main body inner side surface portion 212 makes it more difficult for food and the like to be placed on the main body flange portion 204, making it easier to serve food and to close the lid 10.

[0059] The angle of inclination of main body inner side surface portion 212 with respect to the horizontal plane is greater than the angle of inclination of main body outer side surface portion 208 with respect to the horizontal plane. By increasing the angle of inclination of main body inner side surface portion 212 with respect to the horizontal plane in this way, food and the like are less likely to be placed on main body flange portion 204, making it easier to serve food.

[0060] The main body inner side portion 212 has a main body stack portion 212S.

[0061] The main body stacking section 212S is provided near the leg section 214L. The main body stacking section 212S includes a plurality of main body stacking sections 212S. Specifically, two main body stacking sections 212S are provided at each of the four corners of the container body 20, corresponding to the positions of the leg sections 214L when the packaging containers 1 are stacked.

[0062] The main body stack section 212S is provided at a position higher than the main body flange section 204. The main body stack section 212S is located at a height between the main body frame section 210 and the main body flange section 204.

The height 212H of the main body stack section 212S is located between the height 210H of the main body frame section 210 and the height 204H of the main body flange section 204.

[0063] The main body stack section 212S includes a main body stack section 212S-1 that protrudes inward and a main body stack section 212S-2 that protrudes outward. Here, the main body stack section 212S that is provided at a position higher than the main body flange section 204 is the main body stack section 212S-1. The main body stack section 212S-2 is provided at a lower position adjacent to the main body stack section 212S-1. By providing the main body stack section 212S in this way, when the container bodies 20 are stacked, the main body stack section 212S-2 of the container body 20 stacked on top of the main body stack section 212S-1 comes into contact with the main body stack section 212S-1, creating a space between the stacked container bodies 20 and preventing the container bodies 20 from sticking together. Furthermore, by providing multiple main body stack sections 212S in this way, tilting of the stacked container bodies 20 is prevented.

[0064] The body bottom 214 is surrounded by the body flange 204. The body bottom 214 is provided inside the body flange 204. The body bottom 214 includes the lowest position in the container body 20. The area occupied by the body bottom 214 is the largest in the container body 20. By providing the body bottom 214 in this way, the body bottom 214 can be used to place food or other items stored thereon.

[0065] The main body bottom 214 has legs 214L.

[0066] The legs 214L are provided on the outer side of the main body bottom 214. A plurality of legs 214L are provided on the main body bottom 214. For example, as shown in FIG. 3, the legs 214L are provided at each of the four corners of the container main body 20. The plurality of legs 214L are each arranged on a diagonal line passing through the center of the container main body 20.

[0067] 4, the legs 214L are provided at the lowest position on the main body bottom 214. By providing the legs 214L in this way, the legs 214L come into contact with the flat surface on which the container body 20 is placed and support the entire container body 20, thereby stabilizing the container body 20 or the packaging container 1.

[0068] In this embodiment, the container body 20 includes a body flange portion 204, a body frame portion 210 that is located inside and higher than the body flange portion 204 and has a width narrower than the width of the body flange portion 204, and a body bottom portion 214 that is located inside the body frame, includes the lowest position, and has legs 214L. This makes it easy to see food contained in the container body 20 in three dimensions and makes it less likely to shift out of position. Therefore, by using this embodiment, it is possible to provide a container body 20 that improves the appearance of food while preventing food from shifting out of position.

[0069] (Fitting of container body and lid) The fitting of the lid body 10 and the container body 20 will be described with reference to Figs. 5 to 6. Figs. 5 and 6 are enlarged cross-sectional views of a packaging container according to one embodiment of the present invention. Specifically, Fig. 5 is an enlarged view of the area surrounded by the dashed line in Fig. 4, and Fig. 6 is an enlarged view of a portion of the area surrounded by the dashed line in Fig. 4. In Figs. 5 and 6, the cut cross sections of the lid body 10 and the container body 20 are shown thicker than they actually are for emphasis.

[0070] As shown in Fig. 5, the lid 10 can close the container body 20 by fitting the fitting portion 102J and the skirt protrusion 202C together. At this time, the lid skirt portion 102 is provided outside the main body skirt portion 202. The lid side surface portion 108-1 is located outside the main body outer side surface portion 208. The lid flange portion 104 is provided outside the main body frame portion 210.

[0071] When the lid 10 closes the container body 20, the body outer surface portion 208 and the lid side surface portion 108 are separated from each other, as shown in Figure 6. The inclination angle 108A of the lid side surface portion 108 relative to the horizontal plane is greater than the inclination angle 208A of the body outer surface portion 208 relative to the horizontal plane. This creates a space 1G between the lid side surface portion 108-1 and the body outer surface portion 208. This space 1G prevents the food from getting caught between the lid 10 and the container body 20, even if the food contained therein protrudes from the container body 20.

[0072] In this embodiment, the packaging container 1 is provided with a main body frame 210 that is provided inside the lid flange 104 at a position higher than the lid flange 104, thereby preventing food from getting caught between the lid 10 and the container body 20. Furthermore, by providing the main body frame 210 that is provided at a position higher than the lid flange 104, the food contained in the container body 20 is easily visible in three dimensions and is less likely to shift out of position. Therefore, by using this embodiment, it is possible to provide a packaging container 1 that improves the appearance of food while preventing food from shifting out of position.

[0073] Within the scope of the concept of the present invention, a person skilled in the art may conceive of various modifications and alterations, and it is understood that these modifications and alterations also fall within the scope of the present invention. For example, to the above-described embodiment, a person skilled in the art may appropriately add or delete components, combine or change the design of the embodiments, or add or omit processing or change conditions, and these modifications and alterations are also included within the scope of the present invention as long as they maintain the gist of the present invention.
