Description

本発明は、容器供給装置およびそれを用いた米飯処理機構に関し、特に、容器積層体の最下部に位置する容器を取り出す技術に関するものである。 The present invention relates to a container supply device and a cooked rice processing mechanism using the same, and particularly to a technique for taking out a container located at the bottom of a stack of containers.

食品工場や店舗などにおいては、容器収容部から次工程に対して1枚ずつ容器を供給する容器供給装置が用いられており、この容器供給装置から供給された容器に対して米飯やおかずの盛り付けが行われる。 In food factories, stores, etc., container feeding devices are used that feed containers one by one from a container accommodating section to the next process, and rice and side dishes are placed in the containers supplied from this container feeding device. will be held.

容器供給装置では、容器収容部に積層して収容された容器積層体を下から支持する板バネなどの支持部材と、容器積層体の最下部の容器を下方へ取り出す取出部とを備えている。そして、取出部による取出方式としては、最下部の容器を吸着しておいて支持部材の支持力に抗して引き抜く吸着方式や、支持部材を一時的に支持解除位置に退避させておいて最下部の容器を自重落下させる落下方式などがある。 The container supply device includes a support member such as a leaf spring that supports the stack of containers stacked and housed in the container accommodating section from below, and a take-out section that takes out the lowest container of the stack of containers downward. . The extraction method using the extraction unit includes a suction method in which the container at the bottom is sucked and pulled out against the support force of the support member, and a suction method in which the container at the bottom is pulled out against the supporting force of the support member, and a method in which the support member is temporarily retracted to the support release position and the container at the bottom is pulled out against the support force of the support member. There is a dropping method that allows the lower container to fall under its own weight.

ここで、吸着方式には、吸着パッドを容器の底面に押し当てて吸着する方式(パッド方式)や、ブロワに接続された吸引孔に負圧で容器を吸着する方式(ブロワ方式)などがある。 Here, the suction methods include a method in which a suction pad is pressed against the bottom of the container to adsorb it (pad method), and a method in which the container is adsorbed using negative pressure through a suction hole connected to a blower (blower method). .

なお、容器供給装置における容器の取り出しについては、例えば、特許文献1(特開2002-308222号公報)、特許文献2(特開2010-001040号公報)、特許文献3(特開2015-000812号公報)などに記載の技術が知られている。 Regarding the removal of containers in the container supply device, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-308222), Patent Document 2 (Japanese Patent Application Laid-open No. 2010-001040), and Patent Document 3 (Japanese Patent Application Laid-open No. 2015-000812). The technology described in the following publications is known.

特開2002-308222号公報JP2002-308222A 特開2010-001040号公報Japanese Patent Application Publication No. 2010-001040 特開2015-000812号公報Japanese Patent Application Publication No. 2015-000812

しかしながら、前述したパッド方式では、吸着パッドを容器の底面に当てなければならないが、容器が変わると容器の底面の位置も変わるために吸着パッドの配置変更が必要になり、操作が煩雑になってしまう。 However, in the pad method described above, the suction pad must be placed on the bottom of the container, but when the container is changed, the position of the bottom of the container also changes, making it necessary to change the placement of the suction pad, making the operation complicated. Put it away.

吸着パッドを多数個配置して必ず一部が容器の底面に当たるようにすれば、このような問題はなくなる。しかしながら、米飯やおかずが盛り付けられる容器は非常に軽量なため、吸着パッドを多数個配置して容器の底面に当てるようにすると、吸着パッドの弾力で容器が持ち上がって支持部材に支持されている姿勢が変わってしまい、容器が取り出されないなどのトラブルが発生することになる。 This problem can be eliminated by arranging a large number of suction pads so that some of them are always in contact with the bottom of the container. However, since the containers in which rice and side dishes are served are very lightweight, if a large number of suction pads are placed and placed against the bottom of the container, the elasticity of the suction pads will lift the container into a position where it is supported by the support member. This may cause problems such as the container not being removed.

一方、ブロワ方式では吸着力が弱く、容器積層体から容器を取り出すことができない場合がある。ブロワの能力を大きくすれば容器の取出不良は防止できるが、装置のコストアップやブロワ動作に伴う騒音発生という新たな問題が生じてしまう。 On the other hand, with the blower method, the adsorption force is weak and the containers may not be able to be removed from the container stack. If the capacity of the blower is increased, defective container ejection can be prevented, but new problems arise such as an increase in the cost of the device and the generation of noise due to the operation of the blower.

そして、このような問題は、容器が上向きになって上下方向に積層した容器積層体からの容器の取り出しのみならず、容器が伏せて上下方向に積層した容器積層体や、容器を横並びに積層した容器積層体における容器の取り出しでも発生する可能性が考えられる。 Such problems occur not only when removing containers from a stack of containers stacked vertically with the containers facing upward, but also when removing containers from a stack of containers where the containers are stacked face down and stacked vertically, or when containers are stacked side by side. It is thought that this may occur even when containers are removed from a stack of containers.

本発明は、上述の技術的背景からなされたものであって、容器の形状を問わずに容器積層体から確実に容器を取り出すことのできる容器供給装置およびそれを用いた米飯処理機構を提供することを目的とする。 The present invention has been made in view of the above-mentioned technical background, and provides a container feeding device that can reliably take out containers from a stack of containers regardless of the shape of the container, and a cooked rice processing mechanism using the same.

It is set in. Further, a cooked rice conveyor 21 is provided that conveys cooked rice R from a cooked rice supply device (not shown). Further, in front of the cooked rice conveyor 21 in the conveyance direction, a loading plate 23 is installed to drop and input the cooked rice R transferred from the cooked rice conveyor 21 by the transfer plate 22. This loading plate 23 is provided directly above the container t held on the holding stage 20 with a space therebetween, and is in the closed position in a horizontal state, and rotates downward around both ends to be in the loading position. It is made up of two plates facing each other.

したがって、投入板23を閉鎖位置にしておいてその上に移載板22により米飯Rを載置し、併せて保持ステージ20に容器tを設置しておき、投入板23を下方に回動させて閉鎖位置から開放位置に移動すれば、投入板23上の米飯Rが容器tの米飯盛付領域taへ自重により落下投入される。 Therefore, with the input plate 23 in the closed position, the cooked rice R is placed on it by the transfer plate 22, the container t is also placed on the holding stage 20, and the input plate 23 is rotated downward. When the container t moves from the closed position to the open position, the cooked rice R on the loading plate 23 is dropped by its own weight into the cooked rice serving area ta of the container t.

図1および図2において、米飯投入装置M2で米飯Rの投入された容器tを次工程へ搬送する搬送装置M3は、保持ステージ20に保持されている容器tの下方に位置する第1の排出コンベア31と、第1の排出コンベア31と連続的に設けられた第2の排出コンベア32とからなる。そして、容器tに米飯Rが投入されて保持ステージ20が相互に離間する方向に移動すると、容器tは第1の排出コンベア31上に落下する。そして、落下した容器tは、第1の排出コンベア31から第2の排出コンベア32へと搬送されて次工程へと送られる。 In FIGS. 1 and 2, a transport device M3 that transports the container t into which cooked rice R has been charged by the cooked rice charging device M2 to the next process is connected to a first discharger located below the container t held on the holding stage 20. It consists of a conveyor 31 and a second discharge conveyor 32 provided continuously with the first discharge conveyor 31. Then, when the cooked rice R is put into the container t and the holding stages 20 move in a direction away from each other, the container t falls onto the first discharge conveyor 31. Then, the dropped container t is conveyed from the first discharge conveyor 31 to the second discharge conveyor 32 and sent to the next process.

さて、容器取出ハンドラ12は、図6および図7に示すように、上部に設置された平板部12aと、平板部12aの中央に形成された吸引孔(圧接部)12bと、吸引孔12bの周囲に形成された複数の貫通孔12aaから出没可能に設けられた複数の吸着パッド12cとを備えており、図示しない駆動モータからの駆動により昇降動作を行う。 Now, as shown in FIGS. 6 and 7, the container removal handler 12 includes a flat plate part 12a installed at the top, a suction hole (pressure contact part) 12b formed in the center of the flat plate part 12a, and a suction hole 12b. It is provided with a plurality of suction pads 12c provided so as to be retractable from a plurality of through holes 12aa formed around the periphery, and is moved up and down by driving from a drive motor (not shown).

ここで、平板部12aは容器取出ハンドラ12が上昇したときに容器積層体Tの最下部に位置する容器tの底面に接触する。また、吸引孔12bは図示しないブロワに接続されており、平板部12aが容器t(容器積層体Tの最下部に位置する容器t)の底面に接触したときに当該容器tを負圧吸引して平板部12aに圧接させる。 Here, the flat plate portion 12a comes into contact with the bottom surface of the container t located at the bottom of the container stack T when the container removal handler 12 is raised. In addition, the suction hole 12b is connected to a blower (not shown), and when the flat plate portion 12a contacts the bottom surface of the container t (the container t located at the bottom of the container stack T), the suction hole 12b sucks the container t under negative pressure. to press against the flat plate portion 12a.

吸着パッド12cは、平板部12aと、当該平板部12aの裏面の四隅に取り付けられたステー12dを介して下方に設置された基台12eとで形成された空間内に配置されている。 The suction pad 12c is arranged in a space formed by a flat plate part 12a and a base 12e installed below via stays 12d attached to the four corners of the back surface of the flat plate part 12a.

例えばゴム製の蛇腹構造となった吸着パッド12cは、平板部12aに形成された吸引孔12bと共通のブロワに接続されており、容器取出ハンドラ12自体の昇降動作とは独立して昇降可能になって貫通孔12aaから出没する。そして、図6に示すように、待機位置では平板部12aの下方になっており、図7に示すように、容器tを吸着するための吸着位置では貫通孔12aaから上昇する。 For example, the suction pad 12c, which has a bellows structure made of rubber, is connected to a common blower with the suction hole 12b formed in the flat plate part 12a, and can be raised and lowered independently of the raising and lowering movement of the container removal handler 12 itself. Then, it appears and disappears from the through hole 12aa. As shown in FIG. 6, it is below the flat plate part 12a in the standby position, and as shown in FIG. 7, it rises from the through hole 12aa in the suction position for suctioning the container t.

なお、吸着パッド12cを複数設けたのは、様々な容器tの形状に対応するためである。すなわち、吸着パッド12cを複数設けておけば、どのような容器tの形状(底面形状)であっても、必ず一部の吸着パッド12cにより容器tの底面を吸着することができるからである。 Note that the reason why a plurality of suction pads 12c are provided is to accommodate various shapes of containers t. That is, if a plurality of suction pads 12c are provided, no matter what shape (bottom shape) the container t has, some of the suction pads 12c can always suction the bottom surface of the container t.

このような構造を有する容器取出ハンドラ12は制御部Sにより動作が制御されており、後述する要領により容器収容部10に積層された容器積層体Tから容器tを1枚ずつ取り出す。 The operation of the container take-out handler 12 having such a structure is controlled by the control section S, and takes out the containers t one by one from the container stack T stacked in the container accommodating section 10 in a manner described later.

次に、本実施の形態の容器供給装置において、制御部Sで実行される容器tを取り出すための制御について、図8~図13を用いて説明する。ここで、図8~図13は、容器積層体から容器を取り出すときの容器取出ハンドラの動作を連続的に示す説明図である。 Next, the control for taking out the container t executed by the control section S in the container supplying apparatus of this embodiment will be explained using FIGS. 8 to 13. Here, FIGS. 8 to 13 are explanatory diagrams continuously showing the operation of the container take-out handler when taking out containers from the container stack.

図8に示すように、待機状態では、容器取出ハンドラ12は、平板部12aが容器積層体Tの最下部に位置する容器tに対して下方へ離間した位置となっている。 As shown in FIG. 8, in the standby state, the container takeout handler 12 is in a position where the flat plate portion 12a is spaced downward from the container t located at the bottom of the container stack T.

この待機状態から、第1の制御として、図9に示すように、ブロワを作動させて吸引孔12bに負圧吸引力を発生させながら、平板部12aが容器tの底面に接触する位置まで容器取出ハンドラ12を上昇させる。すると、容器tは吸引孔12bに吸着されて平板部12aに圧接し、当該平板部12aの平面に沿った姿勢に規制される。 From this standby state, as a first control, as shown in FIG. 9, while operating the blower to generate a negative pressure suction force in the suction hole 12b, the container is brought to a position where the flat plate part 12a contacts the bottom surface of the container t. The take-out handler 12 is raised. Then, the container t is attracted to the suction hole 12b and comes into pressure contact with the flat plate part 12a, and is regulated in a posture along the plane of the flat plate part 12a.

続いて、第2の制御として、図10に示すように、貫通孔12aaから突出するように吸着パッド12cを上昇させて容器t(より詳しくは、容器tの底面)を吸着する。このとき、容器tは吸引孔12bによって平板部12aに圧接しているので、吸着パッド12cが貫通孔12aaから上昇すると、複数の吸着パッド12cの内で容器tの底面に当たった吸着パッド12c(つまり容器tを吸着している吸着パッド12c)は、容器tの底面に圧縮されて変形する。これにより、容器tは平板部12aの平面に沿った姿勢が保持されることになり、上昇した吸着パッド12cによって姿勢が変化することはない。なお、容器tの底面に当たっていない吸着パッド12c(つまり容器tを吸着していない吸着パッド12c)は、貫通孔12aaから平板部12a上に突出する。 Subsequently, as a second control, as shown in FIG. 10, the suction pad 12c is raised so as to protrude from the through hole 12aa to suction the container t (more specifically, the bottom surface of the container t). At this time, since the container t is in pressure contact with the flat plate part 12a by the suction hole 12b, when the suction pad 12c rises from the through hole 12aa, the suction pad 12c (of the plurality of suction pads 12c) that hits the bottom surface of the container t ( In other words, the suction pad 12c) that is suctioning the container t is compressed and deformed by the bottom surface of the container t. Thereby, the attitude of the container t along the plane of the flat plate portion 12a is maintained, and the attitude is not changed by the raised suction pad 12c. Note that the suction pad 12c that is not in contact with the bottom surface of the container t (that is, the suction pad 12c that is not suctioning the container t) protrudes onto the flat plate portion 12a from the through hole 12aa.

このようにして吸着パッド12cによって容器tを吸着したならば、次に、第3の制御として、図11に示すように、吸引孔12bによる圧接状態および吸着パッド12cによる吸着状態を保持したままで容器取出ハンドラ12を下降させ、容器tを板バネ14(図4、図5)の支持力に抗して下方へ引き抜いて取り出す。なお、容器取出ハンドラ12により容器tが容器積層体Tから引き抜かれたならば、引き抜かれた容器tの直上に位置していた容器tが最下部になり、板バネ14に支持されることになる。 Once the container t has been suctioned by the suction pad 12c in this manner, as shown in FIG. The container take-out handler 12 is lowered, and the container t is pulled out downward against the supporting force of the leaf spring 14 (FIGS. 4 and 5). Note that when the container t is pulled out from the container stack T by the container removal handler 12, the container t that was located directly above the pulled out container t becomes the lowest position and is supported by the leaf spring 14. Become.

さて、容器取出ハンドラ12によって容器tが取り出されたならば、第4の制御として、図12に示すように、吸引孔12bによる容器tの平板部12aへの圧接および吸着パッド12cによる容器tの吸着を解除する。これにより、容器tは、容器取出ハンドラ12上に単に載っているだけの状態になる。 Now, once the container t has been taken out by the container take-out handler 12, as shown in FIG. 12, as shown in FIG. Cancel adsorption. As a result, the container t is simply placed on the container removal handler 12.

そこで、最後に、第5の制御として、図13に示すように、プッシャ15により容器取出ハンドラ12上の容器tを押して容器搬送コンベア11に移載する。これにより、容器tは次工程である米飯投入装置M2に向けて送り出される。なお、送出手段としては、本実施の形態のプッシャ15のように容器tを押して送り出す機構以外であってもよい。 Finally, as a fifth control, as shown in FIG. 13, the pusher 15 pushes the container t on the container take-out handler 12 and transfers it to the container conveyor 11. As a result, the container t is sent toward the next step, the cooked rice feeding device M2. Note that the feeding means may be other than a mechanism for pushing and feeding the container t like the pusher 15 of this embodiment.

以上により、制御部Sによる一連の容器の取り出し動作が完了し、図8に示す待機状態へと戻る。 With the above, a series of container unloading operations by the control section S are completed, and the system returns to the standby state shown in FIG. 8.

このように、本実施の形態の容器供給装置M1によれば、容器取出ハンドラ12の吸引孔12bにより容器tを平板部12aに圧接しておいて吸着パッド12cで吸着し、当該容器取出ハンドラ12を下降させて容器tを下方へ引き抜いて取り出すようにしているので、容器tを吸着している吸着パッド12cは、容器tの底面に圧縮されて変形する。 As described above, according to the container supply device M1 of the present embodiment, the container t is brought into pressure contact with the flat plate portion 12a by the suction hole 12b of the container take-out handler 12, and the container t is sucked by the suction pad 12c. Since the suction pad 12c, which is suctioning the container t, is compressed and deformed by the bottom surface of the container t, the container t is lowered and the container t is pulled out downward.

したがって、容器tは平板部12aの平面に沿った姿勢が保持されることになるので、軽量な容器tが吸着パッド12cによって姿勢が変化して取り出されなくなるようなことがなくなる。 Therefore, since the container t is maintained in a posture along the plane of the flat plate portion 12a, there is no possibility that the lightweight container t will not be taken out due to a change in posture due to the suction pad 12c.

しかも、吸着パッド12cが複数設けられているので、どのような底面形状の容器tであっても、必ず一部の吸着パッド12cにより吸着することができる。 Furthermore, since a plurality of suction pads 12c are provided, no matter what kind of bottom shape the container t has, it can always be suctioned by some of the suction pads 12c.

これにより、容器tの形状を問わずに、容器積層体Tから確実に容器tを取り出すことが可能になる。 This makes it possible to reliably take out the container t from the container stack T regardless of the shape of the container t.

以上本発明者によってなされた発明を実施の形態に基づき具体的に説明したが、本明細書で開示された実施の形態はすべての点で例示であって、開示された技術に限定されるものではない。すなわち、本発明の技術的な範囲は、前記の実施の形態における説明に基づいて制限的に解釈されるものでなく、あくまでも特許請求の範囲の記載に従って解釈されるべきであり、特許請求の範囲の記載技術と均等な技術および特許請求の範囲の要旨を逸脱しない限りにおけるすべての変更が含まれる。 Although the invention made by the present inventor has been specifically explained based on the embodiments above, the embodiments disclosed in this specification are illustrative in all respects, and are limited to the disclosed technology. isn't it. In other words, the technical scope of the present invention should not be construed in a limited manner based on the description of the embodiments described above, but should be construed solely in accordance with the description of the claims, and the scope of the claims This invention includes techniques equivalent to the techniques described in , and all changes without departing from the gist of the claims.

例えば、本実施の形態においては、圧接部である吸引孔12bにより容器tを吸引して平板部12aに圧接しているが、吸引以外の手段により圧接するようにしてもよい。一例を挙げると、図14および図15に示すように、圧接部として押付部材16を設け、当該押付部材16により容器tの周縁であるフランジtfを押して平板部12aに圧接することなどが考えられる。 For example, in the present embodiment, the container t is suctioned into pressure contact with the flat plate portion 12a by suction through the suction hole 12b, which is a pressure contact portion, but the pressure contact may be made by means other than suction. For example, as shown in FIGS. 14 and 15, a pressing member 16 may be provided as a press-contact portion, and the press member 16 may press the flange tf, which is the periphery of the container t, to press it against the flat plate portion 12a. .

また、本実施の形態の容器積層体Tは、容器tを上向きにして上下方向に積層した容器積層体Tであった。しかしながら、図16に示すように、ストック台40の上に容器tを伏せて上下方向に積層した容器積層体Tや、図17に示すように、ストック台41の上に容器tを横並びに積層した容器積層体Tであってもよい。なお、このように、本実施の形態において「積層」とは、容器tを上下に積み重ねることに加えて、容器tを横並びに重ねることも含まれる概念である。 Moreover, the container laminate T of this embodiment was a container laminate T in which the containers t were stacked vertically with the containers t facing upward. However, as shown in FIG. 16, the containers T are stacked vertically on top of the stock stand 40, and as shown in FIG. 17, the containers T are stacked horizontally on the stock stand 41. It may also be a container laminate T. As described above, in this embodiment, "stacking" is a concept that includes not only stacking the containers t vertically, but also stacking the containers t side by side.

図16に示す場合、支持部材14は、ストック台40に載せられた容器積層体Tの最上部に位置する容器tを支持している。また、図17に示す場合、支持部材14は、ストック台41に載せられた容器積層体Tの底面が露出した容器tを支持している。なお、図16において、ストック台40はバネ等の付勢部材(図示せず)で上方に付勢されており、これによりストック台40上の容器積層体Tは支持部材14に付勢されている。また、図17において、容器積層体Tはバネ等の付勢部材(図示せず)により支持部材14に付勢されている。したがって、前述した実施の形態では、容器積層体Tの最下部に位置する容器tが取出端に位置する容器tとなっていたが、図16に示す場合では最上部に位置する容器tが、図17に示す場合では側端部に位置する容器tが、それぞれ取出端に位置する容器tとなる。 In the case shown in FIG. 16, the support member 14 supports the container t located at the top of the container stack T placed on the stock stand 40. In the case shown in FIG. Further, in the case shown in FIG. 17, the support member 14 supports a container t placed on a stock stand 41 with the bottom surface of the container stack T exposed. In FIG. 16, the stock stand 40 is urged upward by a biasing member (not shown) such as a spring, and thereby the container stack T on the stock stand 40 is urged against the support member 14. There is. Further, in FIG. 17, the container stack T is biased against the support member 14 by a biasing member (not shown) such as a spring. Therefore, in the embodiment described above, the container t located at the bottom of the container stack T was the container t located at the take-out end, but in the case shown in FIG. 16, the container t located at the top is In the case shown in FIG. 17, the containers t located at the side ends become the containers t located at the take-out ends.

そして、これらの場合での容器取出ハンドラ12は、第1の制御では、上下に180°回転して(図16)、あるいは横方向に90°回転して(図17)、容器tを平板部12aに圧接させる。また、第3の制御では、第1の制御のときとは逆の動きをして容器tを取り出すことになる。 Then, in the first control, the container take-out handler 12 in these cases rotates 180 degrees vertically (FIG. 16) or rotates 90 degrees horizontally (FIG. 17) to remove the container t from the flat plate. 12a. Further, in the third control, the container t is taken out by performing a movement opposite to that in the first control.

さらに、本実施の形態においては、容器積層体Tを支持する支持部材には、容器tが取り出されるときに弾性変形する板バネ14が適用されているが、支持部材の構造としてはこれに限定されるものではない。例えば、容器積層体Tを支持する支持位置と容器積層体Tを支持しない非支持位置とに進退移動や回転する構造の支持部材などとすることができる。 Furthermore, in this embodiment, the support member that supports the container stack T is provided with a plate spring 14 that is elastically deformed when the container t is taken out, but the structure of the support member is limited to this. It is not something that will be done. For example, the support member may have a structure that moves forward and backward or rotates between a support position where the container stack T is supported and a non-support position where the container stack T is not supported.

さらに、米飯Rを容器tに落下投入するための投入板23は、本実施の形態では、両端を軸にして下方に回動すると投入位置となっているが、相互に離間する水平方向にスライドすると投入位置となっていてもよい。 Further, in this embodiment, the input plate 23 for dropping cooked rice R into the container t is at the input position when rotated downward around both ends, but it slides horizontally away from each other. Then, it may be in the input position.

さらに、本実施の形態では、吸引孔12bは平板部12aの中央部に形成され、吸着パッド12cが出没する複数の貫通孔12aaは吸引孔12bの周囲に形成されているが、両者の配置や設置数はこれに限定されるものではない。但し、本実施の形態のようなレイアウトにすれば、容器tの底面中央部が吸引孔12bにより平板部12aに圧接された状態で吸着パッド12cが上昇して底面を吸着するので、容器tはより確実に平板部12aの平面に沿った姿勢に保持されることになるので望ましい。 Furthermore, in this embodiment, the suction hole 12b is formed in the center of the flat plate part 12a, and the plurality of through holes 12aa through which the suction pads 12c appear and retract are formed around the suction hole 12b. The number of installations is not limited to this. However, if the layout of this embodiment is adopted, the suction pad 12c rises and suctions the bottom surface with the center part of the bottom surface of the container t pressed against the flat plate part 12a by the suction hole 12b, so that the container t This is desirable because it more reliably maintains the posture along the plane of the flat plate portion 12a.

以上の説明では、米飯が投入されるトレイ状の容器が例示されているが、丼状容器やカレー容器など、様々な容器が適用できる。さらに、米飯などの食品が投入される容器には限定されず、様々な物を入れる容器に適用することができる。 In the above description, a tray-shaped container into which cooked rice is placed is exemplified, but various containers such as a bowl-shaped container or a curry container can be used. Furthermore, the invention is not limited to containers into which foods such as cooked rice are put, but can be applied to containers into which various things are put.
