Summary of the Invention

Problems to be Solved by the Invention

[0005] Conventional packaging containers as described in Patent Document 1 did not improve the appearance of the contents placed on any of the plurality of placement surfaces more than the contents placed on other placement surfaces.

[0006] One aspect of the present invention aims to realize a packaging container having a plurality of placement surfaces and capable of particularly improving the appearance of the contents placed on some of the placement surfaces.

Means for Solving the Problems

[0007] To solve the aforementioned problems, a packaging container according to one aspect of the present invention comprises a bottom surface and a plurality of mounting surfaces on which contents are placed and which are inclined with respect to the bottom surface, wherein the plurality of mounting surfaces include a first mounting surface on which a support portion is formed that is upward and protruding in a direction perpendicular to the corresponding mounting surface, and a second mounting surface on which the support portion is not formed. [Effects of the Invention]

[0008] According to one aspect of the present invention, a packaging container can be realized that has multiple placement surfaces, and which can particularly improve the appearance of contents placed on some of these placement surfaces. [Brief explanation of the drawing]

[Figure 9] This is a schematic plan view showing another modified example of the container body according to one embodiment of the present invention. [Figure 10] This is a schematic plan view showing yet another modification of the container body according to one embodiment of the present invention. [Modes for carrying out the invention]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The container body (packaging container) 1 according to one embodiment of the present invention is a container capable of containing contents. The contents to be contained in the container body 1 are expected to be food products such as prepared foods, but are not limited to food products. Furthermore, the packaging container according to one embodiment of the present invention may further include a lid (not shown) that can be opened and closed to cover the container body 1.

[0011] In this embodiment, the container body 1 can be formed by thermoforming a resin sheet having a sheet thickness of 0.1 mm to 4 mm, preferably 0.15 mm to 2.5 mm.

[0012] As the resin sheet, thermoplastic resin sheets such as polyolefin resin sheets, polystyrene resin sheets, or polyester resin sheets can be used. The resin used as the raw material for the resin sheet may contain biomass-derived raw materials, biodegradable raw materials, or recycled raw materials.

[0013] The resin sheet may be a foamed sheet or a non-foamed sheet. A laminated sheet can also be used as the resin sheet. Examples of laminated sheets include film-laminated foamed sheets (foamed sheets laminated with a film), co-extruded laminated sheets, or extruded laminated sheets. Examples of thermoforming methods include vacuum forming, thick air forming, vacuum pressure forming, and hot plate forming.

[0014] The color of the container body 1 is not particularly limited. The container body 1 may be a single color or may contain multiple colors. The container body 1 may have a pattern applied to it. Also, only a part of the container body 1 may be colored. For example, the part of the container body 1 that is visible from a plan view may be colored black or the like, while the other parts may not be colored and may be the color of the resin sheet itself (e.g., white).

[0015] [Container body] FIG. 1 is a perspective view of the container body 1 as seen from obliquely above on the front side. FIGS. 2 to 6 are respectively a plan view, a front view, a rear view, a right side view, and a left side view of the container body 1. In this specification, for convenience, as shown in FIGS. 1 to 6, the vertical direction, the front-rear direction, and the left-right direction are defined. When the container body 1 is placed on a horizontal plane, the vertical direction is the vertical direction, and the front-rear direction and the left-right direction respectively correspond to the horizontal direction.

[0016] The container body 1 may be square-shaped or rectangular-shaped in plan view. The outer shape of the container body 1 in plan view is not limited to this, and may be, for example, a triangular shape, a polygonal shape such as a pentagonal shape, or a shape without distinct corners such as a circular shape. In the present embodiment, the container body 1 has a rectangular outer shape having a pair of long sides and a pair of short sides in plan view. The plan view of the container body 1 indicates a state of viewing the container body 1 from above.

[0017] The "rectangular shape" means a shape that can be regarded as a rectangular shape when the container body 1 is viewed as a whole, that is, a substantially rectangular shape. Therefore, for example, a protruding portion may be formed at a part of the periphery of the container body 1, or at least one corner portion may be formed in a polygonal shape instead of a right angle, or may be formed in a curved shape. This also applies to the shape of each part constituting the container body 1 when viewed from all directions.

[0018] As shown in FIGS. 1 to 6, the container body 1 includes a first placement surface (placement surface) 10, a second placement surface (placement surface) 20, a connecting portion 30, a leg portion 40, a peripheral wall portion 50, and a flange portion 60.

[0019] (Placement surface) The placement surface is a planar portion on which the contents are mainly placed. The container body 1 has a plurality of placement surfaces, which are divided into a first placement surface 10 and a second placement surface 20. The first placement surface 10 and the second placement surface 20 are distinguished by the presence or absence of a support portion 11 described later. When simply referred to as the "placement surface" in this specification, it is intended to be a general term for the first placement surface 10 and the second placement surface 20.

[0020] The first mounting surface 10 is inclined with respect to the horizontal plane, and the first bottom surface (base) 13 extends from at least one side that forms the lower end. The first mounting surface 10 is inclined with respect to the first bottom surface 13. Similarly, the second mounting surface 20 is inclined with respect to the horizontal plane, just like the first mounting surface 10, and the second bottom surface (base) 23 extends from at least one side that forms the lower end. The second mounting surface 20 is inclined with respect to the second bottom surface 23.

[0021] The first base surface 13 and the second base surface 23 are planar portions on which contents can be placed. The contents placed on the first placement surface 10 may span across the first placement surface 10 and the first base surface 13. Similarly, the contents placed on the second placement surface 20 may span across the second placement surface 20 and the second base surface 23.

[0022] The first base surface 13 and the second base surface 23 are preferably formed as surfaces parallel to the horizontal plane, but are not limited thereto. The first base surface 13 may be formed as an inclined surface with an inclination angle with respect to the horizontal plane smaller than that of the first mounting surface 10. The same applies to the second base surface 23, which may be formed as an inclined surface with an inclination angle with respect to the horizontal plane smaller than that of the second mounting surface 20.

[0023] The first bottom surface 13 and the second bottom surface 23 reduce the risk of the contents shifting downwards due to sliding caused by the inclination of the first and second mounting surfaces 10 and 20. Therefore, the contents can be stably placed on the inclined first and second mounting surfaces 10 and 20 without compromising the appearance.

[0024] Furthermore, the bottom surface of the container body 1 is not limited to the first bottom surface 13 extending from the first mounting surface 10 and the second bottom surface 23 extending from the second mounting surface 20. The container body 1 only needs to have a bottom surface on which contents can be placed in at least one of its parts. As long as such a bottom surface is formed, the container body 1 does not need to have, for example, at least one of the first bottom surface 13 and the second bottom surface 23.

[0025] (Support part) The first mounting surface 10 has a support portion 11, which consists of a first support portion 11a and a second support portion 11b. In this specification, when simply referred to as "support portion 11," it refers to the collective term for multiple support portions such as the first support portion 11a and the second support portion 11b. On the other hand, no support portion 11 is formed on the second mounting surface 20. The support portion 11 is formed to protrude upward in a direction perpendicular to the corresponding mounting surface. Here, "corresponding mounting surface" refers to the first mounting surface 10 on which the support portion 11 is formed. Since the first mounting surface 10 is inclined, the direction perpendicular to the first mounting surface 10 is inclined with respect to the vertical direction. Hereafter in this specification, for convenience of explanation, the direction in which the support portion 11 etc. protrude from the corresponding mounting surface may be referred to as the "protruding direction."

[0026] The support portion 11 supports the contents placed on the first mounting surface 10, allowing the contents to be positioned higher vertically than on the second mounting surface 20 where the support portion 11 is not present. As a result, if the contents are of the same size, the upper end of the contents placed on the first mounting surface 10 will be higher than the upper end of the contents placed on the second mounting surface 20. Furthermore, by supporting the contents placed on the first mounting surface 10, the support portion 11 reduces the risk of the contents shifting downwards.

[0027] The support section 11, through these functions, can improve the appearance of the contents placed on the first mounting surface 10 and maintain a consistently excellent appearance. In particular, the container body 1 can accommodate the contents so that the appearance of the contents placed on the first mounting surface 10 is better than that of the contents placed on the second mounting surface 20. This can improve the appeal to buyers for purchasing the product.

[0028] The first mounting surface 10 has two support parts 11: a first support part 11a and a second support part 11b. The first support part 11a and the second support part 11b are positioned side by side in the vertical direction on the first mounting surface 10. In other words, the first support part 11a and the second support part 11b are positioned side by side in the inclined direction on the first mounting surface 10 such that the first support part 11a is positioned above. The inclination direction of the first mounting surface 10 is defined as the direction of a hypothetical straight line connecting the upper end position and the lower end position of the first mounting surface 10 by the shortest distance. For example, in the line VII-VII shown in Figure 2, the direction of the straight line portion that overlaps with the first mounting surface 10 is the inclination direction of the first mounting surface 10.

[0029] The number of support parts 11 on the first mounting surface 10 is not limited to two; it may be one or three or more. If the first mounting surface 10 has multiple support parts 11, it can stably support the contents placed on the first mounting surface 10.

[0030] Both the first support portion 11a and the second support portion 11b, when viewed from above in the protruding direction, have a rectangular shape with rounded corners that extends laterally across the first mounting surface 10. The lateral direction of the first mounting surface 10 refers to the surface direction of the first mounting surface 10, which is perpendicular to the inclination direction. Furthermore, the first support portion 11a, located above the first mounting surface 10, has a greater width than the second support portion 11b, located below it. The width of the support portion 11 is defined as the length in the lateral direction of the first mounting surface 10, and is the length of the part of the support portion 11 where this length is maximum.

[0031] The shape of the support portion 11, as viewed from above in the protruding direction, is not limited to this rectangular shape, but may also be a square, polygonal, or circular shape, for example.

[0032] Preferably, the position where the support portion 11 is formed on the first mounting surface 10 is the upper part of the first mounting surface 10. The upper part of the first mounting surface 10 may be the region that occupies the area of ​​the upper half of the first mounting surface 10 in the direction of inclination of the first mounting surface 10. If the support portion 11 is formed in such a position, the height of the contents placed on the first mounting surface 10 can be effectively increased, and the appearance of the contents placed on the first mounting surface 10 can be improved.

[0033] When multiple support parts 11 are formed on the first mounting surface 10, it is preferable that at least one support part 11 is formed on the upper part of the first mounting surface 10 from the viewpoint of improving the appearance of the contents. Furthermore, when multiple support parts 11 are formed on the first mounting surface 10, it is preferable that two or more support parts 11 are formed on the upper part of the first mounting surface 10, and it is more preferable that all of the support parts 11 are formed on the upper part of the first mounting surface 10.

[0034] (rib) The first mounting surface 10 may have a first rib 12. The second mounting surface 20 may have a second rib 22. The first rib 12 and the second rib 22 are formed as convex ridges that protrude upward and perpendicular to the corresponding mounting surface. Here, "corresponding mounting surface" refers to the first mounting surface 10 on which the first rib 12 is formed or the second mounting surface 20 on which the second rib 22 is formed. The first rib 12 and the second rib 22 extend laterally to the corresponding mounting surface, and it is preferable that multiple ribs are formed side by side in the inclined direction of the mounting surface.

[0035] It is preferable that the first rib 12 and the second rib 22 have a shorter protrusion length from the corresponding mounting surface than the support portion 11. The protrusion length from the mounting surface is the length from the base end on the mounting surface side to the other end of the support portion 11, the first rib 12, or the second rib 22 in the protrusion direction.

[0036] Figure 7 is a cross-sectional view of the container body 1 shown in Figure 2, taken along the line VII-VII. As shown in Figure 7, it is preferable that the upper end (position H2) of the first support portion 11a, which is formed on the uppermost side of the first mounting surface 10, is located above the upper end (position H3) of the second rib 22, which is formed on the uppermost side of the second mounting surface 20. Because the protruding length of the support portion 11 is longer than that of the second rib 22, even if the formation position of the first support portion 11a, which is formed on the uppermost side of the first mounting surface 10, is the same as or lower than the formation position of the second rib 22, which is formed on the uppermost side of the second mounting surface 20, the relationship that the height of position H2 > the height of position H3 can be achieved.

[0037] With this configuration, the support portion 11 allows the position of the contents placed on the first mounting surface 10 to be higher than the position of the contents placed on the second mounting surface 20. At the same time, the support portion 11, the first rib 12, and the second rib 22 reduce the risk of the contents moving downwards from the first mounting surface 10 or the second mounting surface 20.

[0038] Preferably, the support portion 11 protrudes 1 mm or more from the first mounting surface 10. The protruding length of the support portion 11 may be 1 mm or more and 10 mm or less, or 2 mm or more and 5 mm or less. If the protruding length of the support portion 11 is such that it can effectively raise the height of the contents, and the appearance of the contents placed on the first mounting surface 10 can be improved.

[0039] Preferably, the protrusion length of the first rib 12 and the second rib 22 from the first mounting surface 10 or the second mounting surface 20 is less than 1 mm. The protrusion length of the first rib 12 and the second rib 22 may be 0.1 mm or more and less than 1 mm, 0.2 mm or more and 0.8 mm or less, or 0.3 mm or more and 0.6 mm or less. If the protrusion lengths of the first rib 12 and the second rib 22 are such lengths, the first rib 12 and the second rib 22 can effectively reduce the unintended downward movement of the contents. Furthermore, even if the second rib 22 is formed on the second mounting surface 20, the position of the contents placed on the first mounting surface 10 and supported by the support part 11 can be made higher than the position of the contents placed on the second mounting surface 20.

[0040] Furthermore, the first rib 12 and the second rib 22 may have a shorter vertical width than the support portion 11. The vertical width of the first rib 12, the second rib 22, and the support portion 11 is defined as the length in the vertical direction, which is the inclination direction of the mounting surface, and is defined as the length of the part of the first rib 12, the second rib 22, and the support portion 11 where this length is maximum.

[0041] The vertical width of the support portion 11 may be, for example, 3 mm to 30 mm, 3.5 mm to 20 mm, or 4 mm to 15 mm. If the vertical width of the support portion 11 is such a length, the support portion 11 can stably support the contents placed on the first mounting surface 10.

[0042] The vertical width of the first rib 12 and the second rib 22 may be 0.2 mm or more and less than 3 mm, 0.5 mm or more and 2 mm or less, or 0.7 mm or more and 1.5 mm or less. If the vertical width of the first rib 12 and the second rib 22 is such a length, it becomes easy to arrange multiple first ribs 12 or second ribs 22 side by side on the first mounting surface 10 and the second mounting surface 20, respectively. Therefore, the risk of the contents placed on the first mounting surface 10 and the second mounting surface 20 shifting downwards can be effectively reduced.

[0043] The first rib 12 and the second rib 22 may be formed on the first bottom surface 13 and the second bottom surface 23, respectively. The first rib 12 is preferably formed on both the first mounting surface 10 and the first bottom surface 13, but may be formed on the first mounting surface 10 and not on the first bottom surface 13. Similarly, the second rib 22 is preferably formed on both the second mounting surface 20 and the second bottom surface 23, but may be formed on the second mounting surface 20 and not on the second bottom surface 23. Furthermore, since the contents placed on the first mounting surface 10 are supported by the support portion 11, the second rib 22 may be formed on the second mounting surface 20, while the first rib 12 may not be formed on the first mounting surface 10.

[0044] (Placement surface arrangement) As shown in Figure 1, the first mounting surface 10 and the second mounting surface 20 are inclined downwards to the right in a direction intersecting the front-to-back direction of the container body 1, and may be arranged side by side in the left-to-right direction such that the first mounting surface 10 is to the left of the second mounting surface 20.

[0045] The direction intersecting the front-to-back direction of the container body 1 is a horizontal direction and may be any direction other than the direction that overlaps with the front-to-back direction of the container body 1. Furthermore, the direction toward the right in the direction intersecting the front-to-back direction of the container body 1 may be the so-called direction toward the true right, which overlaps with the left-to-right direction of the container body 1, or it may be any direction toward the diagonal right. In the container body 1, both the first mounting surface 10 and the second mounting surface 20 are inclined downward toward the front right.

[0046] In this case, the vertical inclination angles (inclination angles with respect to the first bottom surface 13 or the second bottom surface 23) of the first mounting surface 10 and the second mounting surface 20 may be the same or different. Similarly, the inclination in the direction of inclination with respect to the front-to-back direction of the first mounting surface 10 and the second mounting surface 20 may be the same or different. From the viewpoint of improving the uniformity of the contents placed on the first mounting surface 10 and the second mounting surface 20, it is preferable that these inclination angles and inclination directions are the same.

[0047] When the inclination directions of the first mounting surface 10 and the second mounting surface 20 are as described above, it is preferable that the first mounting surface 10 is positioned to the left of the second mounting surface 20. The contents placed on the first mounting surface 10 and the second mounting surface 20 are placed at an angle, sloping downwards to the front right along the inclination direction of these mounting surfaces. In this case, the contents of the container body 1 that are most likely to attract attention are likely to be the contents placed at the highest position on the far left side of the container body 1. Therefore, by forming the first mounting surface 10 on the left side of the container body 1, the contents that are most likely to attract attention can be supported by the support part 11, which can particularly improve the appearance.

[0048] Furthermore, if such a container body 1 is covered with a transparent lid (not shown), it is conceivable that a label indicating the product name, etc., may be superimposed on the lid. It is preferable that such a label be displayed on the front right side of the container body 1, so as not to overlap with the contents, which are considered to be the most likely to attract attention. In this case, it is preferable to support the contents whose visibility is not obstructed by the label by the support part 11, thereby improving their appearance compared to the other contents.

[0049] Conversely, the first mounting surface 10 and the second mounting surface 20 may be arranged side by side in the left-right direction, with the first mounting surface 10 being to the right of the second mounting surface 20, in a direction that intersects with the front-rear direction of the container body 1.

[0050] Furthermore, as described above, when the first mounting surface 10 and the second mounting surface 20 are arranged side by side, the first front wall portion 17 and the second rear wall portion 26 may be formed continuously, as shown in Figure 2, etc. With such a configuration, it is easy to shorten the distance between the first mounting surface 10 and the second mounting surface 20, and the areas of the first mounting surface 10 and the second mounting surface 20 can be set to be larger. In addition, the uniformity of the contents placed on the first mounting surface 10 and the second mounting surface 20 can be improved.

[0051] (Side wall section) From the first mounting surface 10, the first side wall portion 14 is formed by extending upward from at least a portion of each end in the direction perpendicular to the inclination direction of the first mounting surface 10. The ends in the direction perpendicular to the inclination direction of the first mounting surface 10 are the two side ends of the first mounting surface 10. Similarly, from the second mounting surface 20, the second side wall portion 24 is formed by extending upward from at least a portion of each end in the direction perpendicular to the inclination direction of the second mounting surface 20.

[0052] Preferably, the first side wall portion 14 constitutes the side wall of both the first mounting surface 10 and the first bottom surface 13. Preferably, the first side wall portion 14 is formed by extending upward from both ends of the first bottom surface 13 in a direction perpendicular to the inclination direction of the first mounting surface 10. In other words, the first side wall portion 14 constitutes the lateral wall portion of the mounting space for the contents formed by the first mounting surface 10 and the first bottom surface 13.

[0053] The first side wall portion 14 effectively reduces the risk that the contents placed on the first mounting surface 10 may move laterally beyond the range of the first mounting surface 10 and fall into grooves 41, etc., which will be described later, thus spoiling the appearance.

[0054] (Pillow Club) Preferably, a first cushion portion 15 is formed extending upward from the upper end of the first mounting surface 10. The first cushion portion 15 is located above the rear side in the inclination direction of the first mounting surface 10 and is a portion with a greater inclination angle with respect to the first bottom surface 13 than the first mounting surface 10. The first cushion portion 15 may constitute at least a part of the upper end of the container body 1.

[0055] Furthermore, as shown in Figure 7, the upper end (position H1) of the first cushion portion 15 is located above the upper end (position H2) of the first support portion 11a. By forming such a first cushion portion 15 above the first mounting surface 10, the contents placed on the first mounting surface 10 can be improved in appearance by being supported by the support portion 11, while reducing the risk of them moving behind the first mounting surface 10 and spoiling their appearance.

[0056] Furthermore, the first cushion portion 15 allows the contents placed on the first placement surface 10 to remain in place between the first cushion portion 15 and the first support portion 11a even if they slide downward along the slope. In addition, a similar effect of retaining the contents can be expected between the first support portion 11a and the second support portion 11b. Moreover, by placing the contents so as to straddle and follow both the first cushion portion 15 and the first support portion 11a, it is possible to create a dynamic (moving) presentation of the contents that resembles waves.

[0057] (rear wall) A first rear wall portion 16 may extend from the upper end of the first support portion 15 toward the rear of the first mounting surface 10. The rear of the first mounting surface 10 is the direction parallel to the inclination direction of the first mounting surface 10 in the horizontal direction, and indicates the direction toward the first support portion 15. The first rear wall portion 16 constitutes the rear wall portion of the first mounting surface 10.

[0058] (front wall) Furthermore, a first front wall portion 17 may be formed extending from the front end of the first bottom surface 13 toward the front of the first bottom surface 13. The front of the first bottom surface 13 is also the front of the first mounting surface 10. The front of the first mounting surface 10 is the direction parallel to the inclination direction of the first mounting surface 10 in the horizontal direction, and indicates the direction toward the first bottom surface 13.

[0059] The first front wall portion 17 constitutes the front wall portion of the storage space for the contents, which is formed by the first mounting surface 10 and the first bottom surface 13. The first front wall portion 17 effectively reduces the risk that the contents placed on the first mounting surface 10 and the first bottom surface 13 may move forward beyond the range of the first bottom surface 13 and fall into grooves 41, etc., which will be described later, thus spoiling the appearance.

[0060] Even if the container body 1 does not have a first bottom surface 13, the first front wall portion 17 may be formed by extending from the front end of the first mounting surface 10 toward the front of the first mounting surface 10.

[0061] The second side wall portion 24, the second support portion 25, the second rear wall portion 26, and the second front wall portion 27 perform the same functions as the first side wall portion 14, the first support portion 15, the first rear wall portion 16, and the first front wall portion 17 on the second mounting surface 20 and the second bottom surface 23, respectively. Therefore, further explanation of these portions is omitted.

[0062] (Connection part) The connecting portion 30 is a part that connects the first mounting surface 10 or the second mounting surface 20 to the peripheral wall portion 50, which will be described later. In this embodiment, the container body 1 has six connecting portions 30. These positions are three between the peripheral wall portion 50 and the first mounting surface 10, and three between the peripheral wall portion 50 and the second mounting surface 20.

[0063] More specifically, three of the connecting portions 30 are formed between the first side wall portion 14 and the peripheral wall portion 50 on the front side of the first mounting surface 10, between the left portion of the first rear wall portion 16 and the peripheral wall portion 50, and between the rear portion of the first rear wall portion 16 and the peripheral wall portion 50. The other three connecting portions 30 are formed between the second side wall portion 24 and the peripheral wall portion 50 on the front side of the second mounting surface 20, between the rear portion of the second rear wall portion 26 and the peripheral wall portion 50, and between the second front wall portion 27 and the peripheral wall portion 50.

[0064] The connecting portion 30 improves the rigidity of the container body 1. Furthermore, small packets containing seasonings such as sauces can be placed on the upper surface of the connecting portion 30. In this case, the packets can be housed in the container body 1 without coming into contact with the contents placed on the first and second mounting surfaces 10 and 20.

[0065] The container body 1 does not necessarily have to have a connecting portion 30. For example, there may be no connecting portion 30 between the first mounting surface 10 and the second mounting surface and the peripheral wall portion 50, and the first mounting surface 10 and the second mounting surface may be surrounded by a groove portion 41, which will be described later.

[0066] (Legs and grooves) The legs 40 are formed to protrude downward from the container body 1 and include the contact surface of the container body 1. In a plan view, the legs 40 are formed at the four corners of the container body 1 and at the central portion of each of the two long sides of the periphery of the container body 1. Preferably, the legs 40 are formed at positions that include the four corners of the container body 1 in a plan view. Alternatively, the container body 1 may not have distinct legs 40, and the bottom surface may function as the contact surface.

[0067] The legs 40 may protrude downward, forming a groove 41 on the inner surface of the container body 1. The groove 41 may be a portion into which liquids seeping from food or other contents placed on the first and second mounting surfaces 10 and 20 flow in and are held. By forming a groove 41 in the container body 1, liquids such as oil generated from the contents of the container body 1 can be held separately from the contents.

[0068] The grooves 41 may be formed in locations other than where the legs 40 are formed. That is, the lower ends of some of the grooves 41 may be located above the contact surface of the legs 40 and not in contact with the ground.

[0069] (peripheral wall) The peripheral wall portion 50 is the part that forms the peripheral wall of the container body 1. The peripheral wall portion 50 has a portion that extends upward from the outer end of the connecting portion 30 and a portion that extends upward from the outer ends of the leg portion 40 and the groove portion 41.

[0070] Here, the outer end of the connecting portion 30 is the outer edge of the container body 1 on the upper surface of the connecting portion 30. In other words, the outer end of the connecting portion 30 is the connection portion between the connecting portion 30 and the peripheral wall portion 50. Furthermore, the positions of the outer ends of the leg portion 40 and the groove portion 41 are not particularly limited and may vary depending on the shape of the container body 1. In this embodiment, for example, the outer ends of the leg portion 40 and the groove portion 41 may be defined as the portions of the container body 1 that are at the same height as the outer end of the connecting portion 30 in the vertical direction.

[0071] (Flange section) The flange portion 60 is a frame-shaped portion extending outward from the upper end of the peripheral wall portion 50. The outer shape of the flange portion 60 is the same as the outer shape of the container body 1 in a plan view, and in this embodiment it is rectangular. If the packaging container according to this embodiment further comprises a lid (not shown), the flange portion 60 may be a portion that supports the lid, or it may be a portion that fits with the lid and is fixed to the lid.

[0072] As shown in Figure 7, it is preferable that the upper end (position H4) of the flange portion 60 is located below the upper end (position H2) of the first support portion 11a. With this configuration, the height of the contents placed on the first mounting surface 10 and supported by the support portion 11 will never be lower than the flange portion 60. Therefore, the contents placed on the first mounting surface 10 can be easily seen from above and from any direction (front, back, left, or right), improving the appearance of the contents.

[0073] [Variation] Various variations of the container body 1 according to one embodiment of the present invention are conceivable. Figures 8 to 10 are schematic plan views showing various modified examples of the container body 1. For the sake of simplicity, Figures 8 to 10 only schematically show the arrangement of the first mounting surface 10, the second mounting surface 20, and the support part 11, and do not limit the shape and arrangement of the container body for each modified example.

[0074] Examples of modified container bodies 1 include, for example, container bodies 1a, 1b, or 1c, as shown in Figures 8 to 10, which have three or more mounting surfaces, with only one of these mounting surfaces being the first mounting surface 10.

[0075] The container body 1a shown in Figure 8 has three mounting surfaces, comprising one first mounting surface 10 and two second mounting surfaces 20. If these mounting surfaces are inclined downward toward the front right, similar to the container body 1, then it is preferable that the first mounting surface 10 is located furthest to the left of the three mounting surfaces.

[0076] Furthermore, the container body 1b shown in Figure 9 has four mounting surfaces, comprising one first mounting surface 10 and three second mounting surfaces 20. If these mounting surfaces are inclined downward toward the front right, similar to the container body 1, then it is preferable that the first mounting surface 10 is located furthest to the left and furthest back of the three mounting surfaces. In other words, the first mounting surface 10 is inclined downward toward the right in a direction intersecting the front-to-back direction of the container body 1b, and the first mounting surface 10 may be positioned as the leftmost and furthest back of the multiple mounting surfaces.

[0077] This is also true for the container body 1c shown in Figure 10. The container body 1c has six mounting surfaces, comprising one first mounting surface 10 and five second mounting surfaces 20. The mounting surfaces are arranged in three rows in the left-right direction and two columns in the front-back direction, with the first mounting surface 10 located on the leftmost and rearmost side.

[0078] In addition, in modified versions of the container body 1, the number of mounting surfaces is not limited to these, and may be, for example, five or seven or more. Furthermore, in modified versions of the container body 1 that have three or more mounting surfaces, the number of first mounting surfaces 10 may be one, but may be two or more depending on the number and size of the contents in which you wish to particularly improve the appearance.

[0079] Thus, in each modified example of the container body 1, the contents placed on the first mounting surface 10 and supported by the support portion 11 are made more conspicuous than the contents placed on the multiple second mounting surfaces 20, thereby improving the overall appearance of the contents. Furthermore, by positioning the first mounting surface 10 towards the rear of the container body 1 (the far right or far left and furthest back) according to the inclination direction of the first mounting surface 10, the appearance of the contents placed on the first mounting surface 10 can be greatly improved.

[0080] 〔summary〕 A packaging container according to Embodiment 1 of the present invention comprises a bottom surface and a plurality of mounting surfaces on which contents are placed and which are inclined with respect to the bottom surface, wherein the plurality of mounting surfaces include a first mounting surface on which a support portion is formed that is upward and protruding in a direction perpendicular to the corresponding mounting surface, and a second mounting surface on which the support portion is not formed.

[0081] In the packaging container according to embodiment 2 of the present invention, in embodiment 1, the packaging container is rectangular in plan view, the first mounting surface and the second mounting surface are inclined downward toward the right in a direction intersecting the front-to-back direction of the packaging container, and they may be arranged side by side in the left-to-right direction such that the first mounting surface is to the left of the second mounting surface.

[0082] The packaging container according to embodiment 3 of the present invention has three or more of the aforementioned mounting surfaces in embodiment 1 or 2, and only one of the aforementioned mounting surfaces may be the first mounting surface.

[0083] A packaging container according to embodiment 4 of the present invention may further include, in any of embodiments 1 to 3, side wall portions extending upward from at least a portion of each of the ends in a direction perpendicular to the inclination direction on the surface described above.
