Summary of the Invention
Problems to be Solved by the Invention
[0004] In the food storage bag as disclosed in Patent Document 1 above, when storing foods with different seasonings attached to the surface, the seasonings on the surface move and the tastes are mixed. Therefore, when storing a plurality of foods, only one type of food with the same seasoning can be stored.
[0005] An object of the present invention is to provide a food storage bag that can store foods with different surface seasonings without mixing the tastes.
Means for Solving the Problems
[0006] The food storage bag of the present invention is a food storage bag in which food is stored in a storage section formed by overlapping sheet-like packaging materials in the front-to-back direction, comprising: a gusseted ridge portion formed by overlapping the packaging materials in a mountain shape; a front sheet portion disposed in front of the gusseted ridge portion; and a back sheet portion disposed behind the gusseted ridge portion, wherein the storage section includes a front storage section formed in a valley shape between the gusseted ridge portion and the front sheet portion; and a rear storage section formed in a valley shape between the gusseted ridge portion and the back sheet portion, wherein the height position of the upper edge of the front sheet portion is lower than the height position of the upper edge of the gusseted ridge portion; and the height position of the upper edge of the back sheet portion is higher than the height position of the upper edge of the gusseted ridge portion. [Effects of the Invention]
[0007] According to the present invention, it is possible to provide a food storage bag that can accommodate foods with different surface seasonings without mixing the flavors. [Brief explanation of the drawing]

[Figure 4] This diagram corresponds to Figure 3 and is a side cross-sectional view showing the lid covering the storage compartment. [Figure 5] This is a side view showing a modified food storage bag. [Figure 6] This figure corresponds to Figure 2 and is a view taken in the direction of arrow II in Figure 5. [Modes for carrying out the invention]
[0009] The embodiments will be described below with reference to the drawings. Figure 1 is a front view of the food storage bag 1 according to the embodiment. Figure 2 is a view taken in the direction of arrow II in Figure 1, and is a bottom view showing the bottom of the food storage bag 1. Figure 3 is a side cross-sectional view corresponding to the cross-section along line III-III in Figure 1, showing the state in which food 5 is stored in the food storage bag 1.
[0010] As shown in Figures 1 to 3, the food storage bag 1 according to this embodiment has two storage compartments 10 in which food 5 is stored. The two storage compartments 10 are formed by folding and overlapping a sheet-like packaging material 20 in the front-to-back direction when the food storage bag 1 is in use. Here, "front and back" refers to the front-to-back direction of the paper surface in Figure 1, where the front side of the paper surface is the front and the back side is the rear. In Figures 2 and 3, the front is indicated by arrow F and the rear by arrow R. Also, in Figures 1 and 3, the top side of the food storage bag 1 in use is indicated by T and the bottom side by B, and in Figures 1 and 2, the width direction (left-to-right direction) of the food storage bag 1 in use is indicated by W. The directions such as front-to-back, up-to-down, and width direction in the following description are based on the directions shown in these figures. The same indications for these directions are also used in Figures 4 to 6.
[0011] The packaging material 20 is a flexible sheet formed from, for example, a resin such as polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate, or nylon (polyamide), or aluminum foil. For example, a single-layer structure of a film made from one of the above resins or aluminum foils, or a multi-layer structure in which one or more types of films are laminated together, can be used as the packaging material 20. In the case of a single-layer structure, the thickness is, for example, about 20 to 100 μm, and in the case of a multi-layer structure, the thickness is, for example, about 30 to 200 μm. The packaging material 20 may also be paper, or resin-coated paper in which the surface of the paper is coated with a resin such as silicone or vinyl.
[0012] As shown in Figure 3, one sheet of packaging material 20 is folded in a roughly W-shape in a side cross-sectional view, thereby overlapping in the front-to-back direction. This overlapping of the packaging material 20 results in a food storage bag 1 comprising a gusseted ridge portion 30 formed by the overlapping of the packaging material 20 in a mountain-like shape, a front sheet portion 40 positioned in front of the gusseted ridge portion 30, and a back sheet portion 50 positioned behind the gusseted ridge portion 30. The gusseted ridge portion 30 includes a front hanging portion 31 extending forward from the upper edge 30a that constitutes the ridge-like top of the gusseted ridge portion 30, and a rear hanging portion 32 extending backward from the upper edge 30a.
[0013] The two storage sections 10 include a front storage section 11 formed in a valley shape between the gusseted ridge 30 and the front sheet section 40, and a rear storage section 12 formed in a valley shape between the gusseted ridge 30 and the rear sheet section 50. The front sheet section 40 is the portion that extends from the lower edge 31a of the front hanging portion 31 of the gusseted ridge 30, rising upwards toward the front. The upper edge of the front sheet section 40 has a folded portion 41 that is folded forwards toward the front. The rear sheet section 50 is the portion that extends from the lower edge 32a of the rear hanging portion 32 of the gusseted ridge 30, rising upwards toward the rear. The folded portion 41 may be folded backwards. Also, the folded portion 41 may not be formed at all.
[0014] The front and rear hanging portions 31 and 32 of the gusseted ridge 30 overlap each other in the front-to-back direction at both ends in the width direction, and these ends are joined along the entire length in the vertical direction. The front sheet portion 40, excluding the folded portion 41, is joined to the front surface of the front hanging portion 31 by overlapping it. The back sheet portion 50 is joined to the back surface of the rear hanging portion 32 by overlapping it. Therefore, the overlapping ends of the front sheet portion 40, front hanging portion 31, rear hanging portion 32, and back sheet portion 50, which are the four front and rear parts of the packaging material 20, are joined together to form a seal portion 21 of a predetermined width. The seal portion 21 is formed by means of heat welding (heat sealing), ultrasonic welding, adhesive bonding, etc. The folded portion 41 may be joined to parts of the front sheet portion 40 other than the folded portion 41 at both ends in the width direction. The entire surface of the folded portion 41 may be joined to the portion of the front sheet portion 40 other than the folded portion 41.
[0015] Furthermore, the front hanging portion 31 and the rear hanging portion 32 may be joined not only at both ends in the width direction, but entirely, thereby making the front housing portion 11 and the rear housing portion 12 a single unit.
[0016] The front storage section 11 is a pocket-shaped space enclosed by the front hanging portion 31 of the gusseted ridge 30, the front sheet portion 40, and the sealing portions 21 on both sides in the width direction. The front storage section 11 has a front opening 11a at the top. The front storage section 11 has a bottom gusset 60 with a mountain-shaped side cross-section that folds upward. The bottom gusset 60 is a gusset that increases the depth of the bottom of the front storage section 11. Since the height position of the bottom gusset 60 is lower than the height position of the upper edge 40a of the front sheet portion 40, the reduction in storage capacity is suppressed.
[0017] The rear storage section 12 is a pocket-shaped space enclosed by the rear hanging portion 32 of the gusseted ridge 30, the back sheet portion 50, and the sealing portions 21 on both sides in the width direction. The rear storage section 12 has a rear opening 12a at the top.
[0018] Incidentally, the bottom gusset 60 provided in the front storage portion 11 may be located at the bottom of the rear storage portion 12. The bottom gusset 60 may be provided in both the front storage portion 11 and the rear storage portion 12, or may be provided in at least one of them. Incidentally, the bottom gusset 60 may not be provided.
[0019] When no food 5 is stored in each of the storage portions 11 and 12, the food storage bag 1 collapses flat as shown in FIG. 1 and has a rectangular shape in a front view.
[0020] As described above, both end portions in the width direction of the packaging material 20 that respectively form the front storage portion 11 and the rear storage portion 12 and face each other are joined by the seal portion 21. And the front vertical lower portion 31 that forms the front storage portion 11 and the rear vertical lower portion 32 that forms the rear storage portion 12 between the seal portions 21 at both ends in the width direction are not joined. Therefore, the front vertical lower portion 31 of the front storage portion 11 excluding the seal portion 21 and the rear vertical lower portion 32 of the rear storage portion 12 can be separated in the front-rear direction as shown in FIG. 2. FIG. 2 is a bottom view of the food storage bag 1 when the portions other than both end portions in the width direction of the front vertical lower portion 31 and the rear vertical lower portion 32 are separated.
[0021] As shown in FIGS. 1 and 3, the height position of the upper edge 40a of the front sheet portion 40 of the food storage bag 1 in the use state is lower than the height position of the upper edge 30a of the gusset ridge portion 30. The height difference, that is, the vertical dimension between the upper edge 40a of the front sheet portion 40 and the upper edge 30a of the gusset ridge portion 30 is preferably about 2 mm or more and 20 mm or less, and more preferably about 5 mm or more and 15 mm. Incidentally, the upper edge 40a of the front sheet portion 40 in this case is the portion that becomes the fold of the folded piece portion 41.
[0022] In the food storage bag 1 in use, the height of the upper edge 50a of the back sheet portion 50 is higher than the height of the upper edge 30a of the gusset portion 30. This height difference, i.e., the vertical dimension between the upper edge 50a of the back sheet portion 50 and the upper edge 30a of the gusset portion 30, corresponds to the length of the lid portion 51, which will be described later. Here, if a part of the back sheet portion 50 constitutes the lid portion 51, the height of the upper edge 50a of the back sheet portion 50 refers to the height of the upper edge 50a of the back sheet portion 50 when the back sheet portion 50 including the lid portion 51 is extended. As shown in Figures 1 and 3, the back sheet portion 50 has a fold 52 that serves as the starting point for the lid portion 51.
[0023] Figure 4 is a side cross-sectional view corresponding to Figure 3, showing the state in which the front storage section 11 and the rear storage section 12 are covered together by the lid section 51 included in the back sheet section 50. The lid section 51 is the portion of the back sheet section 50 on the upper edge 50a side of the fold line 52. The fold line 52 is formed in a straight line extending in the width direction. When the food storage bag 1 is in use, the height position of the fold line 52 is higher than the height position of the upper edge 30a of the gusset section 30. The difference in height, that is, the vertical dimension between the fold line 52 and the upper edge 30a of the gusset section 30, is preferably about 2 mm to 30 mm, and more preferably about 5 mm to 10 mm.
[0024] The fold line 52 can be created, for example, by removing the front surface layer of the back sheet portion 50 to form a half-cut, or by creating a weak line through perforation. Alternatively, the fold line 52 can also be created by creasing the back sheet portion 50. However, the form of the fold line 52 is not limited to these.
[0025] The vertical length of the lid portion 51, that is, the vertical length from the fold 52 of the back sheet portion 50 to the upper edge 50a, is such that, as shown in Figure 4, it covers the front storage portion 11 and the rear storage portion 12 together when food 5 is stored in each of them, and the upper edge 50a of the back sheet portion 50, which is the end of the lid portion 51, extends to the front of the front sheet portion 40. As shown in Figure 4, it is preferable that the length of the lid portion 51 is such that it can cover the folded portion 41 of the front sheet portion 40 from the front.
[0026] The food storage bag 1 according to this embodiment has the above configuration. Next, a method for using this food storage bag 1 will be described.
[0027] Figures 3 and 4 show the state in which the first food item 5A, designated as food item 5, is stored in the front storage section 11, and the second food item 5B, also designated as food item 5, is stored in the rear storage section 12. Specifically, the first food item 5A is "yakitori (grilled chicken skewers) with sauce" served on a skewer, and the second food item 5B is "yakitori (grilled chicken skewers) with salt" served on a skewer. Therefore, the first food item 5A and the second food item 5B are foods that differ in the seasoning applied to their surfaces.
[0028] When using the food storage bag 1, as shown in Figure 3, with the openings 11a and 12a of each storage section 11 and 12 facing upwards, the first food item 5A is placed in the front storage section 11 through the front opening 11a, and the second food item 5B is placed in the rear storage section 12 through the rear opening 12a. When storing the first food item 5A in the front storage section 11, pulling the folded portion 41 forward widens the front opening 11a, making it easier to store the food.
[0029] Next, the lid portion 51 of the back sheet portion 50 is folded forward, and the lid portion 51 covers the front opening 11a of the front storage portion 11 and the rear opening 12a of the rear storage portion 12. The folded portion 41 of the front sheet portion 40 is covered with the tip of the lid portion 51, that is, near the upper edge 50a of the back sheet portion 50, and this area is attached to the front of the front sheet portion 40 with tape 70 to secure it. To secure the lid portion 51 to the front of the front sheet portion 40, it may be attached using the adhesive provided on the back of the tip of the lid portion 51. This makes it possible to carry the food storage bag 1 containing the first food 5A and the second food 5B. To eat the first food 5A and the second food 5B, peel off the tape 70, lift up the lid portion 51, and take out the first food 5A and the second food 5B from the respective storage portions 11 and 12.
[0030] The front storage section 11 and the rear storage section 12 are separated by a gusseted ridge 30. Therefore, when used as described above, the first food item 5A stored in the front storage section 11 and the second food item 5B stored in the rear storage section 12 are stored separately without contact with each other. Furthermore, seasonings adhering to the surface of the first food item 5A, i.e., "sauce" in this case, are stored in the front storage section 11 or adhere to the inner surface of the front storage section 11, but it is difficult for any "sauce" other than that adhering to the surface of the first food item 5A to enter the rear storage section 12. Similarly, seasonings adhering to the surface of the second food item 5B, i.e., "salt" in this case, are stored in the rear storage section 12 or adhere to the inner surface of the rear storage section 12, but it is difficult for any "salt" other than that adhering to the surface of the second food item 5B to enter the front storage section 11. Therefore, the sauce from the first food 5A does not adhere to the salty second food 5B, nor does the salt from the second food 5B adhere to the sauced first food 5A. As a result, the first food 5A and the second food 5B, which have different flavors, can be enjoyed while savoring their respective unique seasonings without their flavors mixing.
[0031] In the food storage bag 1 of this embodiment, the height of the upper edge 40a of the front sheet portion 40 is lower than the height of the upper edge 30a of the gusset portion 30. If the heights of these upper edges 40a and 30a were aligned, or if the upper edge 30a of the gusset portion 30 was lower than the upper edge 40a of the front sheet portion 40, it would be difficult to insert the first food item 5A into the front opening 11a of the front storage portion 11. Similarly, it would be difficult to insert the second food item 5B into the rear opening 12a of the rear storage portion 12. However, because the height of the upper edge 40a of the front sheet portion 40 is lower than the height of the upper edge 30a of the gusset portion 30, when viewed from the front, the upper end of the gusset portion 30 above the upper edge 40a of the front sheet portion 40 is exposed, and by pushing that upper end backward with the first food item 5A, the front opening 11a can be easily opened. This makes it easy to place the first food item 5A into the front storage section 11 through the front opening 11a. Also, since the upper edge 30a of the gusseted ridge 30 is exposed, the rear opening 12a can be easily opened by bending the upper edge 30a forward with a finger or the like. This makes it easy to place the second food item 5B into the rear storage section 12 through the rear opening 12a. In addition, the seasoning adhering to the surface of the first food item 5A and the seasoning adhering to the surface of the second food item 5B are less likely to mix.
[0032] In the food storage bag 1 of this embodiment, the height of the upper edge 50a of the back sheet portion 50 is higher than the height of the upper edge 30a of the gusset portion 30. If the heights of these upper edges 50a and 30a were the same, or if the upper edge 50a of the back sheet portion 50 was lower than the upper edge 30a of the gusset portion 30, it would be difficult to insert the second food item 5B into the rear opening 12a of the rear storage portion 12. However, because the height of the upper edge 50a of the back sheet portion 50 is higher than the height of the upper edge 30a of the gusset portion 30, when viewed from the front, the front surface of the back sheet portion 50 above the upper edge 30a of the gusset portion 30 is exposed. By pushing this front surface backward with the second food item 5B and further bending the upper edge 30a of the gusset portion 30 forward with a finger or the like, the rear opening 12a can be easily opened. This makes it easier to place the second food item 5B into the rear storage compartment 12 through the rear opening 12a. Also, the seasoning adhering to the surface of the second food item 5B is less likely to mix with the seasoning adhering to the surface of the first food item 5A. The upper edge 30a of the gusseted portion 30 is rounded by folding the packaging material 20, which also makes it easier to place a finger on this part and bend it forward, making it easier to insert the second food item 5B into the rear opening 12a. In addition, the gusseted portion 30 is made up of two overlapping sheets and is therefore rigid. This also makes it easier to bend the gusseted portion 30, which functions as a partition, forward, making it easier to insert the second food item 5B into the rear opening 12a.
[0033] In the food storage bag 1 of this embodiment, the back sheet portion 50 includes a lid portion 51 that covers the front storage portion 11 and the rear storage portion 12. That is, the lid portion 51 is provided continuously and integrally as part of the back sheet portion 50. This eliminates the need to prepare a separate lid portion to cover the front storage portion 11 and the rear storage portion 12, resulting in a simpler structure. Furthermore, the lid portion 51 allows for hygienic transport of the food items 5A and 5B stored in the front storage portion 11 and the rear storage portion 12.
[0034] Since the lid portion 51 is formed from the fold 52 of the back sheet portion 50 to the upper edge 50a, the lid portion 51 can be easily installed. Because the height position of the fold 52 is higher than the height position of the upper edge 30a of the gusset portion 30, the front storage portion 11 and the rear storage portion 12 can be reliably covered with the lid portion 51 by folding the lid portion 51 forward from the fold 52.
[0035] In the food storage bag 1 of this embodiment, the front storage section 11 and the rear storage section 12 are formed by joining the widthwise ends of the packaging material 20 that face each other to form a sealing section 21. As a result, the bulk of the food storage bag 1 in the front-to-back direction is reduced, allowing for compact use.
[0036] In the food storage bag 1 of this embodiment, the upper edge of the front sheet portion 40 has a foldable portion 41 that can be folded forward. By pulling this foldable portion 41 forward, the front opening 11a widens, making it easier to store the first food item 5A in the front storage portion 11. The upper edge 40a of the foldable portion 41 is rounded by folding the packaging material 20, which also makes it easier to place your fingers on this portion and bend it forward, making it easier to insert the first food item 5A into the front opening 11a. Furthermore, because the sheet overlaps when the foldable portion 41 is folded, this portion has stiffness. Therefore, this also makes it easier to bend this portion forward with your fingers, making it easier to insert the first food item 5A into the front opening 11a. Thus, seasonings and the like that adhering to the inner surface of the front storage portion 11 do not adhere to your fingers, and the first food item 5A can be stored in the front storage portion 11.
[0037] In the food storage bag 1 of this embodiment, a bottom gusset 60 is provided at the bottom of the front storage section 11, thereby increasing the storage capacity of the front storage section 11 in the front-to-back direction.
[0038] In the above embodiment, the front housing portion 11 and the rear housing portion 12 are formed, and the widthwise ends of the packaging material 20, which face each other, are joined by a sealing portion 21. However, this portion does not need to be joined. Figures 5 and 6 show a modified example of such an embodiment. In Figures 5 and 6, the same reference numerals are used for components identical to those in the above embodiment, and their descriptions are omitted. Only the differences between this modified example and the above embodiment will be described below.
[0039] Figure 5 is a side view of a modified food storage bag 1, where both the front storage section 11 and the rear storage section 12 are flat and do not contain food 5. Figure 6 is a diagram corresponding to Figure 2, and is a view in the direction of arrow VI in Figure 5.
[0040] In the modified food storage bag 1, the front storage section 11 and the rear storage section 12, respectively, are formed by the packaging material 20 facing each other, and their widthwise ends are not joined. That is, the front hanging portion 31 of the front storage section 11 and the rear hanging portion 32 of the rear storage section 12 are not joined at any point. Therefore, as shown in Figures 5 and 6, the front storage section 11 and the rear storage section 12 can be separated in the front-rear direction throughout their entire width.
[0041] If the front storage section 11 and the rear storage section 12 can be separated in the front-rear direction, then both the front storage section 11 and the rear storage section 12 will have more room to bulge in the front-rear direction, thus increasing the storage capacity.
[0042] According to the embodiments described above, the following effects are achieved.
[0043] (1) The food storage bag 1 according to the embodiment is a food storage bag in which food 5 is stored in a storage section 10 formed by overlapping sheet-like packaging material 20 in the front-to-back direction, comprising a gusseted ridge portion 30 formed by overlapping the packaging material 20 in a mountain shape, a front sheet portion 40 positioned in front of the gusseted ridge portion 30, and a back sheet portion 50 positioned behind the gusseted ridge portion 30, wherein the storage section 10 includes a front storage section 11 formed in a valley shape between the gusseted ridge portion 30 and the front sheet portion 40, and a rear storage section 12 formed in a valley shape between the gusseted ridge portion 30 and the back sheet portion 50, the height position of the upper edge 40a of the front sheet portion 40 is lower than the height position of the upper edge 30a of the gusseted ridge portion 30, and the height position of the upper edge 50a of the back sheet portion 50 is higher than the height position of the upper edge 30a of the gusseted ridge portion 30.
[0044] According to the food storage bag 1 of this embodiment, by storing foods 5 with different surface seasonings in the front storage section 11 and the rear storage section 12, the foods 5 can be stored separately while maintaining the form of a single bag. Therefore, the foods 5 can be stored without their flavors mixing, and consumers can enjoy the unique flavors of each food. It is particularly suitable for separating and storing foods that have liquid seasonings or the like attached to their surface, which tend to transfer and mix flavors when they come into contact with other foods. Furthermore, since foods with different seasonings can be stored in one bag, the consumption of bags is reduced, lowering the burden on the environment.
[0045] Because the height of the upper edge 40a of the front sheet portion 40 is lower than the height of the upper edge 30a of the gusseted portion 30, it is easier to store food items 5 in the front storage portion 11. Because the height of the upper edge 50a of the rear sheet portion 50 is higher than the height of the upper edge 30a of the gusseted portion 30, it is easier to store food items 5 in the rear storage portion 12.
[0046] (2) In the food storage bag 1 according to the embodiment described in (1), the back sheet portion 50 includes a lid portion 51 that covers the front storage portion 11 and the rear storage portion 12.
[0047] This allows for hygienic transport of food items 5 stored in the front storage compartment 11 and the rear storage compartment 12. Since the lid 51 is provided continuously and integrally as part of the back sheet 50, there is no need to prepare a separate lid to cover the front storage compartment 11 and the rear storage compartment 12, resulting in a simpler configuration.
[0048] (3) In the food storage bag 1 according to the embodiment described in (1) and (2) above, the back sheet portion 50 has a fold 52 which serves as the starting point for the lid portion 51.
[0049] This makes it easy to install the lid portion 51.
[0050] (4) In the food storage bag 1 according to the embodiment described in (1) to (3) above, it is preferable that the height position of the fold 52 is higher than the height position of the upper edge of the gusseted portion 30.
[0051] This allows the lid portion 51 to be folded forward from the fold line 52, thereby securely covering the front storage portion 11 and the rear storage portion 12 with the lid portion 51.
[0052] (5) In the food storage bag 1 according to the embodiment described in (1) to (4) above, the packaging material 20 that forms the front storage section 11 and the rear storage section 12 and faces each other may be joined together.
[0053] This reduces the bulk of the food storage bag 1 in the front-to-back direction, allowing for compact use.
[0054] (6) In the food storage bag 1 according to the embodiment described in (1) to (4) above, the packaging material 20 may be configured to be spaced apart from each other, with the front storage section 11 and the rear storage section 12 respectively.
[0055] In this configuration, the amount of room for the front storage section 11 and the rear storage section 12 to bulge in the front-rear direction increases, thus increasing the storage capacity.
[0056] (7) In the food storage bag 1 according to the embodiment described in (1) to (6) above, it is preferable that the upper edge of the front sheet portion 40 has a foldable portion 41 that can be folded to the front or rear.
[0057] This makes it easier to place the food 5 into the front storage section 11 by pulling the folded portion 41 forward. In addition, the first food 5A can be placed into the front storage section 11 without seasonings or other substances adhering to the inner surface of the front storage section 11 adhering to your fingers.
[0058] (8) In the food storage bag 1 according to the embodiment described in (1) to (7) above, at least one of the front storage section 11 and the rear storage section 12 may have a bottom gusset 60.
[0059] This increases the storage capacity of the storage section 10, which has a bottom gusset 60, in the front-to-back direction.
[0060] Although a food storage bag 1 according to an embodiment has been described above, the present invention is not limited to this embodiment and can be modified as appropriate.
[0061] For example, in the above embodiment, the food storage bag 1 is constructed by folding a single packaging material 20 in a roughly W-shape in the front-to-back direction, thereby overlapping the pieces in the front-to-back direction. This forms four parts of the packaging material 20: a front sheet portion 40, a front hanging portion 31, a rear hanging portion 32, and a back sheet portion 50. Each of these four parts may be a single sheet of packaging material, and the food storage bag 1 may be constructed by overlapping and joining these four sheets of packaging material. Alternatively, it may be constructed by folding two or three sheets of packaging material as appropriate.
[0062] The food storage bag 1 in the above embodiment has two storage compartments 10 at the front and back, which are for a first food item 5A and a second food item 5B, but there may be three or more storage compartments 10 in the front-to-back direction. [Explanation of Symbols]
