  The present invention relates to a lunch box container used as a lunch box container for take-out, and more particularly, to a lunch box container having an inner lid that partitions the inside of a container body filled with cooked rice into a bottom side and an opening side. .

  Lunch boxes sold for take-out at stores such as bento sales specialty stores, convenience stores, and fast food stores include bowls such as tempura bowls, cutlet bowls, and iron flame bowls. A bowl of rice bowl is filled with cooked rice on the bottom side of the container body having an opening on the upper side, tools such as tempura, tonkatsu or sashimi are placed on the cooked rice, and the opening of the container is covered with an upper lid. The container body and the upper lid are sold in a combined state.

  However, when you take home and eat, the fried garment or sashimi absorbs the water generated from the cooked rice, and you cannot enjoy the crispness of the garment or the freshness of the sashimi decreases. There is a problem that you cannot taste the desired texture. In order to solve such a problem, a rice container for serving that separates cooked rice and ingredients is disclosed in Patent Document 1, and a lunch box is disclosed in Patent Document 2.

  As shown in FIG. 6, the rice container for serving disclosed in Patent Document 1 includes a bowl-shaped container body 111, a downward bowl-shaped upper lid 112 that covers the upper opening of the container body 111, A pair of separable inner lids 113 and a belt-like winding member 114 are provided. Then, cooked rice 115 is packed in the container main body 111, and the opening of the container main body 111 is closed with the inner ends 113a and 113a in contact with each other so that the inner lid 113 covers the cooked rice 115. On the outer peripheral edge of the inner lid 113, downward flange portions 113 b and 113 b that are engaged with the opening edge of the container body 111 and upward flange portions 113 c and 113 c into which the outer peripheral edge of the upper lid 112 is fitted are formed. .

  On the inner lid 113 that closes the opening of the container main body 111, tools 116 such as brocade eggs and sashimi are placed. Therefore, the tool 116 is isolated from the cooked rice 115 by the inner lid 113, and does not absorb the moisture of the cooked rice 115, and can maintain a fresh state. And when the outer periphery of the upper lid 112 is fitted into the upward flanges 113c, 113c of the inner lid 113, the upper lid 112 covers the tool 116, and the container body 111, the inner lid 113, and the upper lid 112 are united. . Then, the container body 111 and the upper lid 112 are wound around the winding member 114 so that the container body 111 and the upper lid 112 are not separated from each other.

  In such a rice container for serving, the container main body 111 and the upper lid 112 are combined, and the flanges 113a and 113b of the pair of inner lids 113 are gripped and pulled out in the opposite direction. Then, the tool 116 is transferred onto the cooked rice 115 and is in a state of being served. When the inner lid 113 is completely pulled out from between the container main body 111 and the upper lid 112, the winding member 114 is loosened. When this winding member 114 is removed from the container main body 111 and the upper lid 112 and the upper lid 112 is removed, the bowl filled with fresh tools 116 can be eaten.

  On the other hand, as shown in FIG. 7, the lunch box disclosed in Patent Document 2 includes a container body 121 having an opening on the upper side, an upper lid 122 that covers the opening of the container body 121, and a container body 121. A pair of middle lids 123 that divide the space surrounded by the upper lid 122 into upper and lower sides, and a moisture absorbent 124 that is attached to the inside of the upper lid 122 are provided. The container body 121 is filled with cooked rice (not shown), and a plurality of holes 121a and 121a are formed in the vicinity of the opening for removing excess water generated from the cooked rice.

  Further, the inner lid 123 is formed of a pair of inner end portions 123a and 123a that are detachably overlapped with each other, and is formed of a foamed resin, polyethylene, or the like having vapor barrier properties. The inner lid 123 has its peripheries 123b and 123b hooked to the upper edge of the container main body 121, and the inner end portions 123a and 123a overlap to cover the cooked rice in the container main body 121. (Not shown). By fitting the opening of the upper lid 122 around the outer periphery of the inner lid 123, the upper lid 122 covers the tool on the inner lid 123 and can be brought home.

Excess water generated from the cooked rice in the container main body 121 is discharged out of the container main body 121 through the plurality of holes 121a and 121a. In addition, moisture generated from the tool on the inner lid 123 is absorbed by the moisture absorbent 124 attached to the upper lid 122. Therefore, the crispness of the tool on the inner lid 123 is maintained. Then, by opening the upper lid 122 and removing the inner lid 123, the ingredient is put on the cooked rice and can be eaten.

  Whether the rice container for serving disclosed in Patent Document 1 or the lunch box disclosed in Patent Document 2, the inner lids 113 and 123 are configured as a separable pair, and the inner end 113a , 123a are in contact with or overlapped with each other. Therefore, a gap is formed in the inner end portions 113a and 123a, and excess water of the cooked rice flows into the space between the inner lids 113 and 123 and the upper lids 112 and 122 from this gap. The tool on the inner lids 113 and 123 may be moistened. In addition, when a food ingredient (hereinafter, mainly referred to as “juice”) having a savory taste like a fried egg that has been melted and heated to a semi-ripe shape is stored on the inner lids 113 and 123, the sessile drips onto the cooked rice. It will fall and the flavor of cooked rice will be damaged.

  Then, this invention makes it a subject to provide the container for lunch which was able to partition the inside of the container main body filled with cooked rice into the bottom part side and the opening part side completely.

A lunch box container according to the present invention has an opening on the upper side, a container body filled with cooked rice on the bottom side, an inner lid that partitions the inside of the container body into a bottom side and an opening side, and the container body A lunch box container having an upper lid that covers an opening, wherein the inner lid is composed of a plurality of sheets such that inner end portions overlap each other, and the inner end portions of the sheets are easily opened. The inner ends of the plurality of sheets are stuck together and pasted together .

  According to this lunch box container, the inner lid is composed of a plurality of sheets, and the inner ends of the sheets are overlapped and adhered over the entire length by an easy-open seal, so the inner ends of the overlapping sheets There is no gap in the part, and the inner lid can be separated by completely partitioning the inside of the container body into the bottom side and the opening side. Therefore, it is possible to prevent the excess water of the cooked rice packed on the bottom side of the container body from dampening the tool placed on the inner lid. Moreover, even if the soup is stored on the inner lid, this soup will not drip onto the cooked rice. Furthermore, when eating a lunch box, the top lid is opened and the outer end of each sheet is pulled in the opposite direction. Then, since the inner end portions of the sheets are adhered to each other by an easy-open seal, the inner end portions of the sheets are easily separated, and the ingredients on the inner lid are transferred onto the cooked rice. It becomes a state.

  According to this lunch box container, the inner sheets of each sheet are peeled so that the inner end of each sheet is not rubbed and the seal is pulled away in the opposite direction. The inner edges of multiple sheets are separated with a small force rather than the seal being peeled off while the front and back sides of each sheet are rubbed together, as in the case of so-called envelope sticking, where the front and back surfaces are stuck together can do.

  Further, in the lunch box container, it is preferable that inner end portions of the plurality of sheets are attached in a sawtooth shape or a wave shape.

  According to this lunch box container, the inner ends of a plurality of sheets are attached in a sawtooth shape or wave shape, so that a concentrated load is applied to each vertex of the sawtooth shape or wave shape. Starting from the apex, the seals of a plurality of sheets can be peeled off with a weaker force than when they are sealed linearly.

  In the lunch box container, a hygroscopic material may be attached to at least one surface of the inner lid.

  According to this lunch box container, the hygroscopic material is adhered to the upper surface side of the inner lid, so that when the ingredient such as a tempura fried or carrot fried on the inner lid is placed, the oil content of the ingredient is reduced. It is absorbed by the hygroscopic material stuck on the lid and does not get wet, and a crispy feeling can be eaten. In addition, when a sashimi-like ingredient is placed on the inner lid, even if moisture oozes out on the surface of the sashimi, the moisture is absorbed by the absorbent material, so that the freshness of the sashimi does not drop and eats be able to. On the other hand, when the hygroscopic material is attached to the lower surface side of the inner lid, excess moisture generated from the cooked rice can be absorbed by the hygroscopic material and the cooked rice can be prevented from sticking. The hygroscopic material may be attached to both the upper surface side and the lower surface side of the inner lid.

  Further, in the lunch box container, the moisture absorbent material is formed in a single sheet shape that is overlapped over almost the entire area of the inner lid, and a planned separation line is formed at a portion overlapping the inner end of each sheet of the inner lid. Preferably it is formed.

  According to this lunch container, when the hygroscopic material is formed in a single sheet having a cut-off line, the hygroscopic material is attached to the upper surface side of the inner lid. Is absorbed by the hygroscopic material. And even if the hygroscopic material is attached to either the upper surface side or the lower surface side of the inner lid, when the inner end portion of the sheet of the inner lid is separated, the hygroscopic material is separated by the planned separation line, and out of the container main body. It can be taken out. Note that the planned cutting line is preferably a perforation, a cut groove or the like.

  According to the present invention, the inner lid that divides the inside of the container main body into the bottom side and the opening side is composed of a plurality of sheets with the inner end portions overlapped, and each inner end portion is pasted over the entire length by an easily openable seal. By being worn, even if moisture is generated from cooked rice stuffed on the bottom side, the moisture on the inner lid can be prevented from getting wet. And since the inner edge part of each sheet | seat is stuck over the full length, even if it puts the tool which has a sap on the inner lid, it can prevent this spill from dripping on the cooked rice.

  And since the inner edge part of each sheet | seat is stuck by the easily openable seal | sticker, an inner cover can be separated easily by pulling the outer edge part of each sheet | seat in the opposite direction. Therefore, the ingredients on the inner lid can be easily transferred onto the cooked rice, and a fresh texture can be tasted. In addition, the lunch box can be used more favorably in stores such as a lunch box sales specialty store without increasing the cost compared to conventional lunch boxes.

  A first embodiment of a lunch box according to the present invention will be described with reference to FIGS. 1 and 2. This 1st Embodiment is a container for lunch boxes suitable for the bowl using the foodstuff which has the juice 3 like the fried egg which melt | dissolved eggs, such as a cutlet bowl and a oyakodon, and heated to a semi-ripe shape. The container for lunch includes a container body 10 having an opening 11 on the upper side, an inner lid 20 that partitions the container body 10 into a bottom 12 side and an opening 11 side, and a lid on the opening 11 of the container body 10. And an upper lid 30 to be provided.

  The container main body 10 is a container that fills the bottom 12 with, for example, cooked rice 1, and can be of any shape such as a bowl shape or a bowl shape, but the outer periphery of the inner lid 20 is open as described later. In order to overlap with the portion 11 and to be easily pulled out, it is preferable that the opening portion 11 adopts a square ridge shape. Further, an outward flange 13 is formed on the periphery of the opening 11 of the container body 10. However, this collar part 13 is not an essential constituent requirement.

  The inner lid 20 partitions the container body 10 into a bottom 12 side and an opening 11 side by a plurality of sheets, for example, two sheets 21 and 21. The sheet 21 is a plastic film for food and is made of a material that can be attached by an easily openable seal 22. The inner end portions 21a and 21a of the sheets 21 and 21 overlap each other and are attached with easy opening by heat sealing over the entire length, for example, with low strength.

  Further, as shown in FIG. 2, the inner end portions 21a and 21a of the sheets 21 and 21 overlap with each other so as to be in a palm, and are attached in a sawtooth shape or a wave shape. The inner end portions 21a and 21a of the sheets 21 and 21 are bonded to each other by the easy-open seal 22 so that the inner end portions 21a and 21a of the attached sheets 21 and 21 are outer ends. When the portions 21b and 21b are pulled in the opposite direction, the seal 22 is peeled off so as to be pulled away. Accordingly, the inner end portions 21a and 21a of the stuck sheets 21 and 21 can be separated.

  Further, by sticking the inner end portions 21a, 21a of the sheets 21, 21 in a sawtooth shape or a wave shape, the seal 22 enters a state in which a concentrated load is applied to each vertex of the sawtooth shape or the wave shape. The inner end portions 21a and 21a of the attached sheets 21 and 21 can be separated with a weaker force than when the apex is torn and the seal 22 is linearly formed.

  The outer end portions 21 b and 21 b of the sheets 21 and 21 are overlapped with the flange portion 13 formed in the opening portion 11 of the container body 10. The outer end portions 21 b and 21 b of the sheets 21 and 21 are not only parallel to the adhered inner end portions 21 a and 21 a but also overlapped with the flange portion 13 over the entire circumference and packed in the container body 10. Excess water in the cooked rice 1 is prevented from flowing into the upper side of the inner lid 20.

  Moreover, the bottom 12 side and the opening part 11 side of the container main body 10 are attached by sticking the outer end parts 21b and 21b of the sheets 21 and 21 and the collar part 13 of the container main body 10 with an easily openable seal. It is possible to completely isolate and prevent the outer end portions 21 b and 21 b of the sheets 21 and 21 from being pulled into the container body 10. However, since it is not easy to stick the outer side portions of the sheets 21 and 21 and the collar portion 13 of the container body 10 with the easy-open seal 22 in the store, the outer end portions 21b and 21b of the sheets 21 and 21 are By opening the container 11 so that the opening 11 of the container main body 10 (the flange 13 when the flange 13 is formed) and the upper lid 30 are fitted to each other, the bottom 12 side of the container main body 10 is opened. It is possible to completely isolate the portion 11 side from being drawn into the container body 10.

  In any case, the inner lid 20 is provided with a flat portion 23 that falls from the opening 11 of the container body 10 and overlaps the surface of the cooked rice 1. On this flat part 23, the ingredient 2 having the soup 3 is placed. Since the inner end portions 21 a and 21 a of the sheets 21 and 21 are adhered over the entire length, the steam 3 does not drip onto the cooked rice 1 in the container body 10. On the contrary, since the excessive water | moisture content of the cooked rice 1 does not flow into the upper side of the inner cover 20, the crispy feeling of the ingredient | tool 2 is not impaired.

  When the upper lid 30 covers the opening 11 of the container main body 10 so as to cover the tool 2 and the container main body 10, the inner lid 20 and the upper lid 30 are combined, a take-out lunch as shown in FIG. Is completed. When eating this lunch, the upper lid 30 is opened and the outer end portions 21b, 21b of the sheets 21, 21 are pulled in the opposite direction. When the outer end portions 21 b and 21 b of the sheets 21 and 21 are attached to the flange portion 13 of the container body 10, the outer end portions 21 b and 21 b of the sheets 21 and 21 are peeled off from the flange portion 13 of the container body 10.

  When the outer end portions 21b and 21b of the sheets 21 and 21 are pulled in the opposite direction, the seals 22 of the inner end portions 21a and 21a of the sheets 21 and 21 are easily peeled and the sheets 21 and 21 are separated. Then, the tool 2 on the inner lid 20 is transferred onto the cooked rice 1 as shown in FIG. Since this ingredient 2 does not contain the steam of the cooked rice 1, it can eat a crisp feeling.

  In the first embodiment, since the two sheets 21 and 21 are adhered over the entire length so that the juice 3 does not drip, the curry roux is placed on the flat portion 23. It can also be made to accumulate. Curry roux is hard to cool by the heat of cooked rice 1 and can be eaten deliciously.
