Description

【０００１】
【発明の属する技術分野】
本発明は、調理済または半調理状態の食品等を密封状態で収納したパウチの電子レンジ加熱用容器に関し、より詳しくは、前記パウチを電子レンジで加熱する際に用いられる電子レンジ加熱用容器に関する。
【０００２】
【従来の技術およびその問題点】
近年、パウチ用として優れた特性を有する包装材料の開発に伴い、特に食品分野における包装体の発展には目覚ましいものがあり、調理した食材を直ちに包装し、調理後の味を損なうことなく、消費者に提供出来るようにしたパウチ入り食品等が多数製造販売されている。
消費者は購入したパウチ入り食品を食する場合、各家庭に普及した電子レンジ等の加熱調理器により加熱することが多い。
【０００３】
この結果、電子レンジ等の加熱調理器による加熱後は、パウチが高温となっているため前記パウチを直ちに電子レンジから取り出すことが出来ず、前記パウチを開封して食する際も食器等の他の容器に移し替えることが困難である。また、これらを無理に行おうとすると火傷の危険性もある。
【０００４】
一方、前記パウチを電子レンジで加熱する際は、加熱によるパウチのバースト（爆発）を防止するため、パウチのコーナー部を開封して、あるいは、例えば、登録実用新案第３０４８３９１号公報または特開平１０−１４７３７１号公報等で提案されているパウチ内の気体の排出機構を設けて、前記バースト（爆発）の防止を行って加熱中の内容物の飛び散りを防止している。
しかしながら、単にパウチを電子レンジ内の受け皿に置いて加熱を行うと、内容物の飛び散りは防止できても、前記受け皿あるいは電子レンジ内に内容物がこぼれてしまうという不都合がある。
【０００５】
また、これらの不都合の防止策として、パウチをスタンディングパウチとして電子レンジ内でスタンディングを可能にすることも提案されているが、パウチの加熱中の内圧上昇によりスタンディングを確実に維持することは困難であり、転倒により電子レンジ内に内容物がこぼれてしまう危険性がある。また、加熱後は、パウチが高温となっているため、加熱後に直ちに電子レンジから取り出すことは困難である。
【０００６】
そこで、本発明の目的は、電子レンジ等の加熱調理器による加熱後のパウチを直ちに取り出すことが出来、食するために、パウチを容器内に収納したままの状態でパウチ内の内容物を食器等の他の容器に移し替えることができると共に、電子レンジ内におけるパウチ内の内容物のこぼれが防止され、かつ、容器の蓋部は、開いた状態では折り返して脚片となり容器を立て掛け可能とする機能を有し、閉じた状態では容器の切り欠き部を覆う梱包部材として機能する。しかも、製造が容易で、取り扱いが極めて簡単なパウチの電子レンジ加熱用容器を提供することにある。
【０００７】
【課題を解決するための手段】
本発明によれば、前面部、背面部、底面部及び両側面部から成るパウチ収納部と、平板部、上面部及び脚片から成る蓋部を有する電子レンジ加熱用容器において、前記パウチ収納部の上方の少なくとも一方のコーナー部にパウチのコーナー部が露出可能に切り欠いた開口部を設け、前記パウチ収納部の背面部にヒンジを介して前記開口部を覆う蓋部を開閉可能に設けると共に、前記蓋部を開いた状態においては前記蓋体を背面部側に折り返して立て掛け可能とし、前記蓋部を閉じた状態においては前記蓋体の平板部の幅が前記切り欠き部よりも大きく成形されると共に、前記切り欠き部が前記蓋体に覆われており、前記蓋体を前記前面部側に閉じて梱包可能としたことを特徴とする電子レンジ加熱用容器が提供される。
【０００８】
また、本発明によれば、蓋部の先端部に係止部を設け、背面部に前記係止部が係合する係合部を設けた上記電子レンジ加熱用容器が提供される。
【０００９】
【発明の実施の形態】
本発明は、前面部、背面部、底面部及び両側面部から成るパウチ収納部の上方に開口部を設け、前記パウチ収納部の背面部にヒンジ部を介して前記開口部を覆う蓋部を開閉可能に設けて電子レンジ加熱用容器とするものである。
そして、前記電子レンジ加熱用容器のパウチ収納部の上方に設けた開口部に対して、パウチのコーナー部、或いは一側が位置するようにパウチが前記パウチ収納部に収納され、前記蓋部によって前記開口部を覆ってパウチの梱包が完了する。
【００１０】
前記電子レンジ加熱用容器において、パウチ収納部の上方の少なくとも一側部に開口部を設けると、パウチのコーナー部が前記開口部から露出するため、パウチを電子レンジ加熱用容器内に保持したまま、加熱後の内容物の取り出しがこの部分から容易に行われる。
【００１１】
また、前記電子レンジ加熱用容器において、パウチ収納部の上方の全面に亙って開口部を設けると、加熱後の内容物の取り出し時に、パウチが加熱用容器から落下し、内容物の取り出しが困難である。
【００１２】
さらに、前記電子レンジ加熱用容器において、蓋部の先端部に係止部を設け、背面部に前記係止部が係合する係合部を設けると、前記蓋部を折り返して係止部を背面部の係合部に係合させることにより、電子レンジ内においてパウチの加熱用容器をスタンディング状態とすることができ、内容物がこぼれることなく、安定して加熱することができる。
【００１３】
