Embodiments for Carrying Out the Invention
[0013] As shown in FIGS. 1 to 3, the food container 1 according to an embodiment of the present invention includes a container body 3 and a lid 5. The food container 1 is, for example, a casserole used for in-flight meals in a vehicle such as an airplane. Also, the food container 1 is made of paper. However, in order to ensure water resistance, the surface of the paper is laminated with polyethylene or the like. Note that the food container 1 may be made of other materials such as synthetic resin. Also, the paper food container 1 is produced, for example, by press-forming a material of a predetermined shape.
[0014] Here, for the sake of convenience of explanation, a predetermined horizontal one direction is defined as the lateral direction, a predetermined other horizontal one direction that is orthogonal to the lateral direction is defined as the longitudinal direction, and a direction orthogonal to both the lateral direction and the longitudinal direction is defined as the vertical direction.
[0015] The container body 3 includes a bottom plate portion (bottom plate) 7 and a side plate portion (side plate) 9 that stands upward from the outer periphery (outer peripheral portion) of the bottom plate portion 7, and is formed in a box shape. Food (edible items) is to be accommodated inside the container body 3. Note that an annular flange portion 11 projects outward from the upper end of the outer periphery of the side plate portion 9.
[0016] The bottom plate portion 7, the side plate portion 9, and the flange portion 11 are generally formed in a flat plate shape. The thickness direction of the bottom plate portion 7 and the flange portion 11 is the vertical direction. The flange portion 11 has an annular shape with a predetermined width dimension when viewed in the vertical direction. The inner side (inside the upper end of the side plate portion 9) of the flange portion 11 is an opening portion 13 formed at the upper end of the container body 3. The flange portion 11 surrounds the opening portion 13 of the container body 3 and projects outward in the longitudinal and lateral directions from the upper end of the side plate portion 9 as described above.
[0017] When taking a cross-section of the container body 3 (side plate portion 9) by a plane orthogonal to the vertical direction, the area of the inner portion of the container body 3 surrounded by the side plate portion 9 gradually increases from bottom to top. As a result, the side plate portion 9 stands obliquely with respect to the vertical direction. And when viewed in the vertical direction, the bottom plate portion 7 is accommodated inside the flange portion 11 (inside the opening portion 13).
[0018] The lid 5 is installed on the container body 3 to close the opening 13 of the container body 3. Further, a protrusion (convex portion) 15 is provided on the lid 5. Stop placing the lid 5 on the container body 3 to close the opening 13 of the container body 3, separate the lid 5 from the container body 3, turn the lid 5 over without turning the container body 3 over (reverse the vertical direction of the lid 5), and place the container body 3 on the lid 5.
[0019] At this time, the protrusion 15 abuts against the container body 3 to prevent displacement of the container body 3 with respect to the lid 5. In other words, the protrusion 15 abuts against the container body 3 to position the container body 3 with respect to the lid 5. The displacement of the container body 3 is a displacement that occurs by rotation about an axis extending in the vertical direction, the horizontal direction, and the vertical direction. Further, in the state where the lid 5 is turned over, the protrusion 15 protrudes upward.
[0020] The lid 5 is generally formed in a flat plate shape, and the thickness direction is the vertical direction both in the state of closing the opening 13 of the container body 3 and in the state of being turned over and placing the container body 3 thereon. In the state where the lid 5 is installed on the container body 3 to close the opening 13 of the container body 3, the lid 5 is integrated with the container body 3, and the protrusion 15 protrudes downward.
[0021] More specifically, the container body 3 (the bottom plate portion 7 and the side plate portion 9) is generally formed in a rectangular box shape, and the value of the vertical dimension of the container body 3 is larger than the value of the horizontal dimension of the container body 3. The lid 5 is generally formed in a rectangular plate shape, and the value of the vertical dimension of the lid 5 is also larger than the value of the horizontal dimension of the lid 5.
[0022] When the lid 5 is turned over without turning over the container body 3 and the container body 3 is placed on the lid 5, the container body 3 is positioned to be biased toward one side in the lateral direction by the protrusion 15. As a result, a portion 17 (see FIG. 3(b)) where the container body 3 is not placed is formed on the other side in the lateral direction of the upper surface of the turned-over lid 5. The portion 17 is, for example, a portion for temporarily placing tools (forks, knives, spoons, chopsticks, etc.) used when eating food in the container body 3.
[0023] The lid 5 is configured to include a lid main body portion 19 and an annular flange portion engaging portion 21. The flange portion engaging portion 21 is provided on the outer peripheral portion of the lid main body portion 19 so as to surround the lid main body portion 19, and is configured to engage with the flange portion 11 of the container body 3 when the lid 5 closes the opening 13 of the container body 3. The flange portion engaging portion 21 is annular with a predetermined width dimension when viewed in the vertical direction. The protrusion 15 is provided on the lid main body portion 19.
[0024] The flange portion engaging portion 21 is configured to include an annular upper end portion engaging portion 23 and an annular edge portion engaging portion 25. The upper end portion engaging portion 23 protrudes from the outer periphery of the lid main body portion 19 in a manner generally extending the lid main body portion 19 and surrounds the lid main body portion 19, and is configured to engage (abut) with the upper end portion of the flange portion 11 of the container body 3 when the lid 5 closes the opening 13 of the container body 3.
[0025] The edge portion engaging portion 25 protrudes from the outer periphery of the upper end portion engaging portion 23 and surrounds the upper end portion engaging portion 23, and is configured to engage with the outer periphery (edge portion) of the flange portion 11 of the container body 3 when the lid 5 closes the opening 13 of the container body 3 so that the flange portion 11 of the container body 3 fits therein. Further, when the lid 5 is turned over, the edge portion engaging portion 25 slightly protrudes (stands up) upward from the upper end portion engaging portion 23. The protruding height of the edge portion engaging portion 25 is constant.
[0026] When the lid 5 is turned over and the container body 3 is placed on the lid 5, the vertical positioning of the container body 3 with respect to the lid 5 is configured to be achieved by the protrusion 15. Also, as shown in FIG. 3(b), when the lid 5 is turned over and the container body 3 is placed on the lid 5, the lateral positioning of the container body 3 with respect to the lid 5 is configured to be achieved by the protrusion 15 of the lid 5 and the edge engaging portion 25 of the lid 5.
[0027] Here, the food container 1 will be described in more detail. The space inside the container body 3 is a food storage space 27 in which food is stored. The food storage space 27 has a frustum of a square pyramid shape in which the area of the lower surface is smaller than the area of the upper surface.
[0028] When viewed in the vertical direction (in plan view), the outer peripheral shape of the flange portion 11 is a rectangle that is long in the vertical direction and short in the horizontal direction. However, since slightly large chamfers are provided at the four corners of the rectangle, the outer peripheral shape of the flange portion 11 appears to be an octagon that is long in the vertical direction. Also, for the purpose of eliminating the sharpness of the corners and facilitating press forming, the boundaries between the bottom plate portion 7 and the side plate portion 9, the boundaries between the side plate portions 9 adjacent to each other, etc. are rounded in an arc shape.
[0029] Also, the container body 3 is symmetric with respect to a plane that includes the center of the container body 3 and is orthogonal to the vertical direction, and is symmetric with respect to a plane that includes the center of the container body 3 and is orthogonal to the horizontal direction.
[0030] The outer peripheral shape of the upper end engaging portion 23 of the lid 5 (the inner peripheral shape of the edge engaging portion 25) is substantially the same shape as the outer peripheral shape of the flange portion 11. The outer peripheral shape of the lid main body portion 19 is also substantially the same shape as the outer peripheral shape of the flange portion 11, but is smaller than the outer peripheral shape of the flange portion 11 by the value of the width dimension of the upper end engaging portion 23.
[0031] As shown in FIG. 4 and the like, the protruding portion 15 is configured to include a longitudinally extending portion 29 and a pair of laterally extending portions 31. The longitudinally extending portion 29 extends long in the longitudinal direction, is located on one side in the lateral direction, and is provided on the lid main body portion 19 so as to be located at the center in the longitudinal direction. One of the pair of laterally extending portions 31 extends laterally from one end in the longitudinal direction of the longitudinally extending portion 29 to the central portion of the lid main body portion 19.
[0032] The other of the pair of laterally extending portions 31 extends laterally from the other end in the longitudinal direction of the longitudinally extending portion 29 to the central portion of the lid main body portion 19. Thus, in plan view, the protruding portion 15 has a “U” shape. The shape of the cross section of the protruding portion 15 (the cross section by a plane orthogonal to the extending direction) is a semi-arc shape as shown in FIG. 3 and the like.
[0033] Also, at the tip portion 37 of the laterally extending portion 31 (the end portion on the side opposite to the longitudinally extending portion 29), in order to facilitate the molding of the lid 5, as shown in FIG. 3(a), the protruding height of the protruding portion 15 gradually decreases toward the tip.
[0034] The lid 5 excluding the protruding portion 15 is symmetric with respect to a plane including the center of the container body 3 and orthogonal to the longitudinal direction, and is symmetric with respect to a plane including the center of the container body 3 and orthogonal to the lateral direction. The protruding portion 15 is symmetric with respect to a plane including the center of the container body 3 and orthogonal to the longitudinal direction.
[0035] As shown in FIG. 3, the food container 1 is configured to be placed, for example, on a table (not shown) provided on the rear portion of the backrest of a vehicle. More specifically, a tray 33 is placed on the table, a sheet 35 made of paper or the like is laid on the upper surface of the tray 33, and the food container 1 is placed on the sheet 35.
[0036] Next, the use of the food container will be described. As shown in Fig. 3(a), the food container 1 is placed on the sheet 35. In the food container 1 shown in Fig. 3(a), food (not shown) is contained inside the container body 3, and the lid 5 closes the opening 13 of the container body 3 with the lid 5.
[0037] In the state shown in Fig. 3(a), remove the lid 5 from the container body 3 and lift the container body 3. Subsequently, turn the lid 5 over and place it on the sheet 35, and place the container body 3 on the lid 5, resulting in the state shown in Fig. 3(b). In the state shown in Fig. 3(b), the container body 3 is sandwiched between the pair of laterally extending portions 31 between the pair of laterally extending portions 31. And the vertical movement of the container body 3 with respect to the lid 5 is blocked. Also, in the state shown in Fig. 3(b), the container body 3 is sandwiched between the vertically extending portion 29 and the flange engaging portion 21 (the portion of the flange engaging portion 21 that is farther from the vertically extending portion 29 among the pair of portions extending in the vertical direction). And the lateral movement of the container body 3 with respect to the lid 5 is blocked.
[0038] The food container 1 is configured to include a container body 3 and a lid 5 provided with a protrusion 15 that contacts the container body 3 when the container body 3 is placed upside down and prevents the container body 3 from shifting. Thereby, it is possible to prevent the container body 3 from slipping and moving on the lid 5 as much as possible.
[0039] Furthermore, to explain further, in the state shown in Fig. 3(b), the friction between the table (not shown) and the tray 33, the friction between the tray 33 and the sheet 35, and the friction between the sheet 35 and the lower surface of the lid 5 are relatively large. Thereby, in the vertical and horizontal directions, the tray 33, the sheet 35, and the lid 5 are not easily moved with respect to the table.
[0040] The friction between the upper surface of the lid 5 and the container body 3 is relatively small due to laminated polyethylene or the like. Furthermore, there may be some water droplets evaporated from food on the upper surface of the lid 5 in the state shown in Fig. 3(a), and the friction may be even smaller. If there were no protrusion 15, the container body 3 would move more easily relative to the lid 5 in the vertical or horizontal direction. However, since the protrusion 15 is provided, the container body 3 is prevented from moving easily relative to the lid 5.
[0041] Also, in the food container 1, when the container body 3 is placed on the lid 5 turned upside down, the protrusion 15 positions the container body 3 to be offset to one side in the lateral direction, so that a portion 17 where the container body 3 is not placed is formed on the other side in the lateral direction of the upper surface of the lid 5. Thereby, forks, knives, spoons, chopsticks, etc. can be temporarily placed on the portion 17 where the container body 3 is not placed, improving the usability of the food container 1.
[0042] Also, in the food container 1, prevention of lateral displacement of the container body 3 relative to the lid 5 when the lid 5 is turned upside down and the container body 3 is placed on the lid 5 is achieved by the protrusion 15 of the lid 5 and the edge engaging portion 25 of the lid 5. Thereby, the shape of the protrusion 15 is simplified by utilizing the edge engaging portion 25.
[0043] Next, the lid 5a according to the modified example will be described with reference to Fig. 4(b).
[0044] The lid 5a according to the modified example has a shape of the protrusion 15a different from that of the lid 5 shown in Fig. 4(a), and is otherwise configured in the same manner as the lid 5 shown in Fig. 4(a) and is used for the container body 3.
[0045] As shown in Fig. 4(b), when the protrusion 15a of the lid 5a is viewed in plan, it is formed in a rectangular annular shape, i.e., in a "square with a hole in the middle" shape. The cross-sectional shape of the protrusion 15a is in a semi-circular arc shape similar to that of the protrusion 15. Also, the lid 5a, including the protrusion 15a, is symmetric with respect to a plane including the center of the lid 5a and orthogonal to the vertical direction, and is symmetric with respect to a plane including the center of the lid 5a and orthogonal to the horizontal direction.
[0046] The state where the lid 5a according to the modification covers the container body 3 is as shown in Fig. 5(a). The state where the lid 5a according to the modification is placed on the container body 3 is as shown in Fig. 5(b). In the state shown in Fig. 5(b), the container body 3 is sandwiched by the protrusions 15a, and the movement of the lid 5a in the vertical and horizontal directions is blocked.
[0047] Also, when the container body 3 and the lid 5a in the state shown in Fig. 5(b) are viewed in plan view, the container body 3 is located slightly inside the lid 5a, and almost all of the container body 3 and almost all of the lid 5a overlap each other.
[0048] Here, the food container 1a according to the first modification will be described with reference to Fig. 6(a). In the food container 1a, a small recess 39 is provided in the bottom plate portion 7 of the container body 3, and a small protrusion 41 is provided in the lid body portion 19 of the lid 5. When the container body 3 is placed on the lid 5, the protrusion 41 fits into the recess 39, and the movement of the container body 3 is blocked.
[0049] In Fig. 6, one recess 39 and one protrusion 41 are provided. However, a plurality of recesses 39 may be provided, a plurality of protrusions 41 may also be provided, and each of the plurality of protrusions 41 may be configured to fit into each of the plurality of recesses 39.
[0050] Next, the food container 1b according to the second modification will be described with reference to Fig. 6(b). In the food container 1b, a slightly larger recess 43 is provided in the bottom plate portion 7 of the container body 3, and a slightly larger protrusion 45 is provided in the lid body portion 19 of the lid 5. When the container body 3 is placed on the lid 5, the protrusion 45 fits into the recess 43, and the movement of the container body 3 is blocked. The protrusion 45 and the recess 43 are formed in a non-circular shape such as a rectangular shape in plan view.
[0051] Next, the food container 1c according to the third modification will be described with reference to Fig. 6(b).
[0052] In the food container 1c according to the third modification example, in a plan view, the container body 3 and the lid 5 are octagonal shapes that approximate a regular octagon, and the food container 1c is different from the food container 1 in that a pair of protrusions (substantially "U"-shaped protrusions) 15b of the lid 5 are provided. The rest of the food container 1c according to the third modification example is configured substantially the same as the food container 1.
[0053] The food container 1c is used, for example, as a small bowl with a lid (SD cup; salad-dessert cup).
[0054] The food container 1c (container body 3, lid 5b) is symmetric with respect to a plane that includes the center of the food container 1c and is orthogonal to the vertical direction, and is symmetric with respect to a plane that includes the center of the food container 1c and is orthogonal to the horizontal direction.
[0055] In a state where the container body 3 is placed on the lid 5b, the movement of the container body 3 in the vertical and horizontal directions is blocked by being sandwiched between the pair of protrusions 15b. Also, when the state where the container body 3 is placed on the lid 5b is viewed in a plan view, substantially all of the container body 3 and substantially all of the lid 5b overlap each other in the same manner as in the case of the food container 1 using the lid 5a.
[0056] Next, regarding the container body 3 of the food container 1c shown in FIGS. 7 and 8, the container body 3 having a stacking function will be described with reference to FIGS. 9 to 11. The container body 3 shown in FIGS. 9 to 11 is different from the container body 3 shown in FIGS. 7 and 8 in that it is configured with small protrusions 47, and the other points are configured the same as the container body 3 shown in FIGS. 7 and 8.
[0057] The protrusions 47 are generated, for example, by press forming during the production of the container body 3. However, after forming the container body 3 shown in FIGS. 7 and 8, the protrusions 47 may be provided separately from the forming using an adhesive or the like. Since the protrusions 47 are generated by press forming, a draft (a gradient that is slightly inclined with respect to the vertical direction) is formed on the protrusions 47.
[0058] The protrusions 47 are provided in a manner slightly protruding outward from the outer surface of the side plate portion 9 of the container body 3, and a plurality of three or more (for example, four) protrusions 47 are provided on one container body 3 in a separated manner from each other. The plurality of protrusions 47 are arranged at positions that equally distribute the container body 3 (side plate portion 9), for example, in the circumferential direction. The size of the protrusion 47 as viewed in the thickness direction of the side plate portion 9 (the protruding direction of the protrusion 47) is extremely small. For example, the size of the protrusion 47 as viewed in the thickness direction of the side plate portion 9 is such that it cannot be visually recognized without a certain degree of scrutiny with the naked eye.
[0059] More specifically, each of the plurality of protrusions 47 is arranged in the vertical direction at an intermediate portion (for example, a portion on the side of the flange portion 11) of the side plate portion 9 of the container body 3 shown in FIGS. 9 to 11. The values of the dimensions of the bottom portion 7 or the flange portion 11 of each of the plurality of protrusions 47 in the vertical direction are equal to each other.
[0060] Also, the plurality of protrusions 47 are provided, for example, at high-rigidity portions of the side plate portion 9 of the container body 3 shown in FIGS. 9 to 11. More specifically, when the side plate portion 9 of the container body 3 shown in FIGS. 9 to 11 is viewed in the vertical direction (in a plan view), the side plate portion 9 is also in an octagonal shape close to a regular octagon, but more precisely, it is in a shape obtained by chamfering the four corners of a square. The outer shape (inner shape) of the cross section of the side plate portion 9 by a plane (a plane orthogonal to the vertical direction) including, for example, the lower ends of the plurality of protrusions 47 is surrounded by four relatively long line segments having equal lengths and four relatively short line segments having equal lengths, and is in an octagonal shape in which the values of the eight inner angles are equal to each other.
[0061] Each of the four protrusions 47 is arranged at the position of the shorter line segment (for example, the center of the short line segment) of the octagon. As a result, each of the four protrusions 47 is provided at a high-rigidity portion of the corner portion of the side plate portion 9. And even when a force directed from the outside of the container body 3 toward the center of the container body 3 is applied to the protrusion 47, the side plate portion 9 of the container body 3 is less likely to bend inward.
[0062] Next, with reference to FIG. 11, the stacking of the two container bodies 3 will be described. The stacking of the container bodies 3 is performed by stacking the container body 3 (3A) with the opening 13 facing upward and the bottom plate portion 7 on the lower side on top of the container body 3 (3B) with the opening 13 facing upward and the bottom plate portion 7 on the lower side.
[0063] When the upper container body 3 (3A) is moved downward with respect to the lower container body 3 (3B) from the state shown in FIG. 11(a), as shown in FIG. 11(b), the stacking of the two container bodies 3 (3A, 3B) is completed.
[0064] In the state shown in FIG. 11(b), the bottom plate portion 7 of the upper container body 3 (3A) and the lower part of the side plate portion 9 enter the inside of the lower container body 3 (3B). Also, in the state shown in FIG. 11(b), the protrusion 47 of the upper container body 3 (3A) abuts against the inner surface of the obliquely standing side plate portion 9 of the lower container body 3 (3B). And there is a predetermined distance in the vertical direction between the flange portion 11 of the upper container body 3 (3A) and the flange portion 11 of the lower container body 3 (3B).
[0065] As a result, the container body 3 has a stacking function, and by inserting a finger between the flange portion 11 of the upper container body 3 (3A) and the flange portion 11 of the lower container body 3 (3B), it becomes easier to separate the two stacked container bodies 3. Also, the lower container body 3 (3B) and the upper container body 3 (3A) are in contact with each other only through the protrusion 47 of the upper container body 3 (3A) (engaging in a substantially point contact manner), and this also makes it easier to separate the two stacked container bodies 3.
[0066] In addition, the stacking of three or more container bodies 3 can be performed in the same manner as the stacking of two container bodies 3. Further, projections similar to the projection 47 may be provided on the container body 3 shown in FIGS. 1 to 6 in the same manner as the container body 3 shown in FIGS. 9 to 11, so that the container body 3 shown in FIGS. 1 to 6 may have a stacking function. When a plurality of projections are provided on the container body 3 shown in FIGS. 1 to 6, each of these plurality of projections is provided at a portion of the side plate portion 9 corresponding to the short sides of the elongated octagon (each of the four corners of the quadrilateral).
[0067] Incidentally, the above-described food container has a container body for housing food therein and a lid for closing the opening of the container body, and when the container body is placed on the lid, a positioning portion (position displacement prevention portion) for preventing displacement of the container body with respect to the lid is provided on at least one of the lid and the container body. This is an example of a food container.
[0068] As described above, the present embodiment has been described, but the present embodiment is not limited to these, and various modifications are possible within the scope of the gist of the present embodiment. For example, the container body 3 may be placed on the lid 5 without turning the lid 5 over to position the container body 3. Further, instead of providing a protrusion, a member having a large coefficient of friction may be provided on either the container body or the lid (for example, a thin sheet-like rubber is attached to either the container body or the lid), and when the container body is placed on the lid, displacement of the container body with respect to the lid may be prevented.
