[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, "upward" refers to a direction that faces upward in the vertical direction when the transport packaging container is placed on a horizontal surface, and "downward" refers to a direction that faces downward in the vertical direction.

[0016] First, Fig. 1 to Fig. 3 show the lid body 100 of the transport packaging container 300 according to the present invention. Fig. 1(a) is an overall perspective view of the front side of the lid body 100, Fig. 1(b) is an overall perspective view of the back side of the lid body 100, Fig. 2(a) is a plan view of the lid body 100, Fig. 2(b) is a bottom view of the lid body 100, Fig. 3(a) is an end view taken along line A-A, and Fig. 3(b) is an end view taken along line B-B.

[0017] As shown in FIGS. 1 to 3 , the lid 100 is made of a synthetic resin sheet, has a shallow dish shape that opens downward, and is generally rectangular in plan view with corners 170 at the four corners. The lid 100 includes a flat, horizontally extending top surface 110, side walls 120 that extend downward from the top surface 110, flat flanges 130 that extend outward from the side walls 120, and a skirt 140 that extends downward from the flanges 130. The skirt 140 located at the corners 170 of the lid 100 is provided with a first lid fitting 150 that is convex inward. The skirt 140 located at the edges 180 between the corners 170 is also provided with a first lid fitting 150 that is convex inward. Furthermore, the side walls 120 located at the corners 170 of the lid 100 are provided with a second lid fitting 160 that is concave inward. The side wall portion 120, the flange portion 130, and the skirt portion 140 are provided continuously or intermittently around the entire circumferential direction of the lid body 100. Furthermore, although the lid body 100 has a generally rectangular shape in a plan view, the shape is not limited to this and may be any shape, such as a generally polygonal shape or a generally circular shape in a plan view.

[0018] Furthermore, protrusions 119 bulging upward from the surface 111 of the top surface 110 are provided near corners 170 of the top surface 110. When transport packaging containers 300 are stacked, the protrusions 119 on the lid 100 of the lower transport packaging container 300 are positioned outside the bottom surface 210 of the container body 200 of the upper transport packaging container 300, thereby maintaining the stacked state so that the upper transport packaging container 300 does not fall. Furthermore, when the transport packaging container 300 is placed upside down on a placement surface, the protrusions 119 also serve as legs that abut against the placement surface. The surface 111 of the top surface 110 is flat, and the back surface 112 of the top surface 110 is also flat. Furthermore, a recess 121 recessed downward is provided in a portion of the side wall 120. Since the recess 121 is recessed downward, as shown in FIG. 3(b), the recess 121 has a stepped shape that bulges downward from the rear surface 112 of the lid 100.

[0019] Furthermore, recess 121 is provided with ventilation holes 129 that penetrate from the inside to the outside. Ventilation holes 129 allow water vapor and the like emitted from food inside transport packaging container 300 to be discharged to the outside, thereby maintaining the freshness of the food. Furthermore, ventilation holes 129 are provided in downwardly bulging recess 121, preventing ventilation holes 129 from being blocked by food (particularly, granular cherry tomatoes or strawberries) and the like that is stored inside. Note that, although ventilation holes 129 are provided in lid 100, this is not a limitation and ventilation holes 129 may not be provided. Furthermore, although a total of four ventilation holes 129 are provided in lid 100, this is not a limitation and any number of ventilation holes greater than one may be provided.

[0020] The lid body 100 is formed by sheet molding (e.g., vacuum molding, pressure molding, hot plate molding) using a sheet-shaped synthetic resin with a thickness of approximately 0.1 mm to 1.0 mm (millimeters). For example, the material for the lid body 100 may be polystyrene, polypropylene, polyethylene, A-PET, polylactic acid, or biaxially stretched versions of these.

[0021] Next, Fig. 4 to Fig. 6 show the container body 200 of the transport packaging container 300 according to the present invention. Fig. 4 is an overall perspective view of the container body 200, Fig. 5 is a plan view of the container body 200, Fig. 6(a) is a CC end view, and Fig. 6(b) is a DD end view.

[0022] 4 to 6, the container body 200 is made of a synthetic resin sheet, has a deep dish shape that opens upward, and is generally rectangular in plan view with corner portions 270 at the four corners. The container body 200 includes a flat, horizontally extending bottom portion 210, a side wall portion 220 that extends upward from the bottom portion 210, a flat flange portion 230 that extends outward from the side wall portion 220, and a skirt portion 240 that extends downward from the flange portion 230. The skirt portion 240 located at the corner portion 270 of the container body 200 is provided with a first container-side fitting portion 250 that is concave toward the inside. The skirt portion 240 located at the side portion 280 between the corner portions 270 is also provided with a first container-side fitting portion 250 that is concave toward the inside. Furthermore, the side wall 220 is provided with a second container-side fitting portion 260 that is convex inward, extending around the corners 270 and sides 280 of the container body 200 in the circumferential direction of the container body 200. The side wall 220, the flange 230, and the skirt 240 are provided continuously or discontinuously around the entire circumferential direction of the container body 200. Although the container body 200 has a generally rectangular shape in a plan view, the shape is not limited thereto and may be any shape, such as a generally polygonal shape or a generally circular shape in a plan view.

[0023] Further, near the side portion 280 of the container body 200, a ventilation portion 290 is provided that is recessed downward from the flange portion 230. This ventilation portion 290 is provided by cutting out a portion of the first container-side fitting portion 250 and the second container-side fitting portion 260, and a non-fitting portion 291 is formed where the first container-side fitting portion 250 and the second container-side fitting portion 260 have been cut out. As will be described later, the non-fitting portion 291 does not fit with the first lid body-side fitting portion 150 and the second lid body-side fitting portion 160 of the lid 100, and forms a gap between the first lid body-side fitting portion 150 and the second lid body-side fitting portion 160 of the lid 100. Further, the ventilation portion 290 includes an inclined portion 292 that slopes outward from the non-fitting portion 291.

[0024] Furthermore, a raised portion 211 is provided on a portion of the bottom surface 210, and the raised portion 211 is provided with a ventilation hole 229 that penetrates from the inside to the outside. The ventilation hole 229 allows water vapor and the like emitted from food inside the transport packaging container 300 to be discharged to the outside, thereby maintaining the freshness of the food. Furthermore, the ventilation hole 229 is provided in the raised portion 211, which is provided on the bottom surface 210, and prevents the ventilation hole 229 from being blocked by the food (particularly, granular cherry tomatoes or strawberries) contained therein. Note that, although the container body 200 is provided with the ventilation hole 229, this is not a limitation and the ventilation hole 229 may not be provided. Furthermore, although the container body 200 is provided with a total of four ventilation holes 229, this is not a limitation and any number of ventilation holes greater than one may be provided.

[0025] The container body 200 is formed by sheet molding (e.g., vacuum molding, compressed air molding, hot plate molding) using a sheet-shaped synthetic resin with a thickness of approximately 0.1 mm to 1.0 mm (millimeters). For example, the material for the container body 200 may be polystyrene, polypropylene, polyethylene, A-PET, polylactic acid, or biaxially stretched versions of these.

[0026] Next, Figures 7 to 9 show the transport packaging container 300 with the lid 100 facing outward attached to the container body 200. Note that Figure 7 is an overall perspective view of the transport packaging container 300, Figure 8(a) is a plan view of the transport packaging container 300, Figure 8(b) is a front view of the transport packaging container 300, Figure 9(a) is an end view taken along line E-E, and Figure 9(b) is an end view taken along line F-F.

[0027] 7 and 8, the transport packaging container 300 is attached so that the lid 100 is placed over the container body 200. At this time, the lid and the container body may or may not be sealed. As shown in Fig. 9, when the lid 100 is fitted to the container body 200 with the surface 111 of the top surface 110 of the lid 100 facing upward, the top surface 110 protrudes upward beyond the first lid-side fitting portion 150, so that the storage space X1 within the transport packaging container 300 is wider.

[0028] Furthermore, when the lid 100 is attached to the container body 200, the first lid-side fitting portion 150 of the lid 100 is tightly fitted to the first container-side fitting portion 250 of the container body 200. Meanwhile, the ventilation portion 290 communicates with the inside and outside of the transport packaging container 300, allowing water vapor and other substances emitted from food in the storage space X1 to be discharged to the outside through the ventilation portion 290, thereby maintaining the freshness of the food. Specifically, the ventilation portion 290 is recessed by cutting out a portion of the first container-side fitting portion 250 downward, so that the ventilation portion 290 does not fit with the first lid-side fitting portion 150 of the lid 100, creating a gap Y1. Furthermore, the non-fitting portion 291 of the ventilation portion 290 is recessed downward below the flange portion 230 of the container body 200 so as not to abut against the flange portion 130 of the lid 100, creating a gap Y2. In this way, the ventilation portion 290 communicates with the inside and outside through the gaps Y1 and Y2.

[0029] Furthermore, the inclined portion 292 of the ventilation portion 290 is inclined outward, and is configured to cover from below the gap Y1 between the first lid body side fitting portion 150 of the lid body 100 and the ventilation portion 290. This effectively prevents foreign matter such as dust from entering the transport packaging container 300 from below the gap Y1.

[0030] Next, Figures 10 to 12 show a transport packaging container 300 in which the lid 100 is attached upside down to the container body 200. Note that Figure 10 is an overall perspective view of the transport packaging container 300, Figure 11(a) is a plan view of the transport packaging container 300, Figure 11(b) is a front view of the transport packaging container 300, Figure 12(a) is a G-G end view, and Figure 12(b) is an H-H end view.

[0031] As shown in Figures 10 and 11, the transport packaging container 300 is attached so that the lid 100 is placed over the container body 200. At this time, the lid and container body may or may not be sealed. As shown in Figure 12, when the lid 100 is fitted to the container body 200 with the back surface 112 of the top surface 110 of the lid 100 facing upward, the top surface 110 is recessed downward relative to the second lid-side fitting portion 160, thereby narrowing the storage space X1 within the transport packaging container 300. In this way, in order to change the storage volume of the transport packaging container 300 depending on the volume of contents to be stored in the transport packaging container 300, the lid 100 can be attached upside down, as shown in Figures 7 and 10. For example, when the contents are granular fruits and vegetables (cherry tomatoes, strawberries, etc.), the size may vary depending on the harvest season. Therefore, the lid 100 can be attached upside down to change the storage volume of the transport packaging container 300 to match the size of the contents. This prevents the contents, such as fruits and vegetables, from rolling around inside the transport packaging container 300 when the transport packaging container 300 is transported, thereby preventing damage to the contents. Furthermore, with the transport packaging container 300 of the present invention, there is no need to prepare two lids of different sizes (depths) to change the storage volume of the transport packaging container 300, which reduces manufacturing costs.

[0032] Furthermore, when the lid 100 is attached to the container body 200, the second container-side fitting portion 260 of the container body 200 is tightly fitted into the second lid-side fitting portion 160 of the lid 100. Meanwhile, the ventilation portion 290 communicates with the inside and outside of the transport packaging container 300, allowing water vapor and other substances emitted from food in the storage space X1 to be discharged to the outside through the ventilation portion 290, thereby maintaining the freshness of the food. Specifically, the ventilation portion 290 is recessed downward by cutting out a portion of the second container-side fitting portion 260, creating a gap Y1. Furthermore, the non-fitting portion 291 of the ventilation portion 290 is recessed downward below the flange portion 230 of the container body 200 so as not to abut against the flange portion 130 of the lid 100, creating a gap Y2. In this way, the ventilation portion 290 communicates with the inside and outside through the gaps Y1 and Y2. In addition, a recess 121 is provided in the side wall portion 120 of the lid body 100 at the portion that overlaps with the ventilation portion 290, so that a gap Y3 is formed in the recessed portion, allowing water vapor and the like to be efficiently discharged from the ventilation portion 290.

[0033] Although the ventilation portion 290 is provided on the container body 200, this is not limiting and the ventilation portion 290 may be provided on the lid 100 side. The configuration of the ventilation portion 290 is not limited to the downwardly recessed configuration shown in FIG. 4 , and may be any configuration that allows communication between the inside and outside of the lid 100 in either state, even when the lid 100 is inverted upside down. Although the first lid-side fitting portion 150 is configured as an inwardly convex shape and the first container-side fitting portion 250 is configured as an inwardly concave shape, this is not limiting and the first lid-side fitting portion 150 and the first container-side fitting portion 250 may have any configuration as long as they can fit together. Although the second lid-side fitting portion 160 is configured as an inwardly concave shape and the second container-side fitting portion 260 is configured as an inwardly convex shape, this is not limiting and the second lid-side fitting portion 160 and the second container-side fitting portion 260 may have any configuration as long as they can fit together.

[0034] The transport packaging container of the present invention is not limited to the above examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications and combinations are also included in the scope of rights.
