Description

本発明は、食料品などを収容することができ、特に電子レンジでの使用に適した包装用容器に関する。 TECHNICAL FIELD The present invention relates to a packaging container capable of containing foodstuffs and the like, and particularly suitable for use in a microwave oven.

コンビニエンスストアやスーパーマーケットなどの小売店では、お弁当やお惣菜などが薄肉の樹脂製容器に収容されて販売されている。このような容器は、温めやすいように容器のまま電子レンジに入れて加熱できる耐熱性を有する設計とされていることが多い。 At retail stores such as convenience stores and supermarkets, bento boxes and side dishes are sold in thin-walled resin containers. Such containers are often designed to have heat resistance so that they can be placed in a microwave oven to heat them easily.

お弁当やお惣菜などを容器に収容したまま電子レンジで加熱すると、食料品から蒸気が発生し、容器の内圧が高まり蓋体を飛ばしてしまうことがある。そのようなことを防ぐために、例えば、蓋体を若干開封し、開口部にやや隙間ができるようにしてから電子レンジに入れて加熱することが行われているが、作業が煩雑になる。 If you heat bento boxes, side dishes, etc. in a microwave oven while they are still in a container, steam will be generated from the food, increasing the internal pressure of the container and causing the lid to blow off. In order to prevent this, for example, the lid is slightly opened to leave a slight gap in the opening, and then the product is placed in a microwave oven to heat it, but this process becomes complicated.

そこで、蓋体にU字状の切れ込みを設けておき、蓋体を開封しなくても蒸気が抜けるようにした包装用容器が開発されている。
例えば、下記特許文献1には、容器本体の開口部を覆う蓋本体と、この蓋本体の上面の一部に形成された凹部と、この凹部に形成された容器本体内で発生する蒸気を抜くための切り欠きで形成した弁と、凹部の周縁部に形成した微小な蒸気抜き溝と、この蒸気抜き溝の外側端部の近傍に外周部が位置して、凹部および該蒸気抜き溝の全部あるいは外周部の一部を残して覆うことができる蓋本体に貼着されたラベルと、を備えた蓋体を有する弁当容器が開示され、この弁当容器は、容器本体内で発生した蒸気が弁を押し上げ、凹部内へ浸入し、この凹部から微小な蒸気抜き溝を通過して、外部へ排出することができるようにしたものである。
Therefore, a packaging container has been developed in which a U-shaped notch is provided in the lid so that steam can escape without opening the lid.
For example, Patent Document 1 below describes a lid body that covers the opening of the container body, a recess formed in a part of the upper surface of the lid body, and a recess formed in the recess to vent steam generated inside the container body. A valve formed by a notch for the purpose of the invention, a minute steam venting groove formed at the periphery of the recess, and an outer periphery located near the outer end of the steam venting groove, and the entire recess and the steam venting groove. Alternatively, a lunch container is disclosed which has a lid body that is equipped with a label affixed to the lid body that can be covered while leaving a part of the outer periphery. The vapor is pushed up, penetrates into the recess, and is discharged from the recess through a minute steam release groove to the outside.

下記特許文献2には、水平方向に対して傾斜した面を設け、この傾斜した面に、回動基部が上側又は下側に位置し、水平方向に対して垂直に入れられた切り込みにより形成された舌状部からなる傾斜弁を形成した蓋体が開示され、この蓋体は、一定圧力を超えると舌状部がスムーズに開いて蒸気を排出することができ、或いは、減圧時に、舌状部が容器内側にスムーズに開き、容器外の空気を取込み、容器の潰れを防ぐことができるものである。 In Patent Document 2 below, a surface is provided that is inclined with respect to the horizontal direction, and the rotating base is located on the upper side or the lower side of the inclined surface and is formed by a cut made perpendicularly to the horizontal direction. Disclosed is a lid body that forms a sloping valve consisting of a tongue-like part, and when the pressure exceeds a certain pressure, the tongue-like part can smoothly open to discharge steam, or when the pressure is reduced, the tongue-like part can open smoothly to discharge steam. The opening smoothly opens inside the container, allowing air from outside the container to be taken in and preventing the container from collapsing.

また、容器本体の縁部に排気用の溝を設けて容器内の蒸気が抜けるようにした容器も開発されている。
例えば、下記特許文献3には、容器本体に形成した容器嵌合部に蓋体の蓋嵌合部を強制的に嵌め合わせることができ、容器本体内に生じる蒸気圧により容器本体から蓋体を持ち上げ、蓋体が持ち上げられた際に容器本体内と容器本体外とを連通開放させる蒸気抜き溝を形成した食品包装容器が開示されている。
Also, a container has been developed in which an exhaust groove is provided at the edge of the container body so that steam inside the container can escape.
For example, Patent Document 3 below discloses that a lid fitting part of a lid body can be forcibly fitted into a container fitting part formed in a container body, and the lid body can be removed from the container body by steam pressure generated inside the container body. A food packaging container is disclosed in which a steam vent groove is formed to allow communication between the inside of the container body and the outside of the container body when the lid is lifted.

従来における容器は、蓋体の天面部にU字状の切れ込みによる弁や容器本体の縁部に蒸気抜き溝などを設けて、電子レンジなどの加熱により発生した蒸気を排出することができるようにしてあるが、大量に蒸気が発生した場合は弁や溝では排出量が少ないため排気が間に合わず、蓋体が押し上げられ、飛散するおそれがあった。 Conventional containers have a U-shaped notch valve on the top of the lid and a steam release groove on the edge of the container body to allow steam generated by heating in a microwave oven to be discharged. However, when a large amount of steam is generated, there is a risk that the valves and grooves will not be able to exhaust the gas in time, causing the lid to be pushed up and blown away.

そこで、本発明の目的は、大量の蒸気などを排出しやすくした包装用容器を提供することにあり、さらに、この容器は、埃などの異物が容器内部に侵入し難くしたものでもある。 SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a packaging container that allows a large amount of steam to be easily discharged, and which also prevents foreign matter such as dust from entering the inside of the container.

本発明の一実施形態の包装用容器は、開口部付近の内面側に嵌合部を有する容器本体と、該嵌合部に内嵌合する被嵌合部を有する蓋体と、該容器本体の周囲に設けたフランジ部と、該蓋体の外縁部に、該容器本体のフランジ部を覆う、フランジ部及び/又はスカート部と、を備えた包装用容器であって、該嵌合部と該被嵌合部とを嵌合させた状態で、該嵌合部と該被嵌合部との間に、容器周方向に延びる空隙の連結通気路と、該連結通気路と交差し、容器内部から容器外部に向かい上下に延びる複数の排出通気路と、を備え、該排出通気路は、容器内部側の吸入口から容器外部側の排出口に向かい窄まるように形成し、該排出口を、該容器本体のフランジ部と該蓋体のフランジ部及び/又はスカート部とが重なり合い閉じる構成としたことを特徴とする。 A packaging container according to an embodiment of the present invention includes a container body having a fitting part on the inner surface near the opening, a lid body having a fitted part that fits inside the fitting part, and the container body. A packaging container comprising: a flange portion provided around the fitting portion; and a flange portion and/or a skirt portion provided on the outer edge of the lid body to cover the flange portion of the container body, In a state in which the fitted portions are fitted, a connecting air passage having a gap extending in the circumferential direction of the container is provided between the fitting portion and the fitted portion, intersecting with the connecting air passage, and connecting the connecting air passage to the container. a plurality of exhaust air passages extending vertically from the inside to the outside of the container; the exhaust air passages are formed to narrow from an inlet on the inside of the container to an outlet on the outside of the container; is characterized in that the flange portion of the container body and the flange portion and/or skirt portion of the lid body overlap and close .

このように、嵌合部と被嵌合部との間に周方向に延びる空隙の連結通気路を設け、また、連結通気路と交差する複数の排出通気路を設けることにより、排出通気路から流入した蒸気が、連結通気路により分散されて他の排出通気路からも排出させることができる。よって、容器内部に大量の蒸気が発生しても複数の排出通気路に適宜分散されて排出され、容器の内圧が高まり蓋体が押し上げられることなどを防ぐことができる。 In this way, by providing a connecting air passage with a gap extending in the circumferential direction between the fitting part and the fitted part, and by providing a plurality of exhaust air passages that intersect with the connecting air passage, it is possible to The inflowing steam is dispersed by the connecting air passage and can also be discharged from other exhaust air passages. Therefore, even if a large amount of steam is generated inside the container, it is appropriately dispersed and discharged through a plurality of exhaust air passages, and it is possible to prevent the internal pressure of the container from increasing and pushing up the lid.

上記形態の包装用容器は、嵌合部に容器周方向に凹む折れ筋を設けることや、被嵌合部に容器周方向に凹む折れ筋を設けることができる。これにより、蓋体を容器本体に嵌合させた際、嵌合部又は被嵌合部の折れ筋が連結通気路となり、蒸気を排出することができる。 In the packaging container of the above embodiment, the fitting portion may be provided with a bent line recessed in the circumferential direction of the container, or the fitted portion may be provided with a bent line recessed in the circumferential direction of the container. Thereby, when the lid body is fitted to the container body, the folded line of the fitting part or the fitted part becomes a connecting ventilation passage, and steam can be discharged.

上記形態の包装用容器は、嵌合部又は被嵌合部に容器内部から容器外部に向かう凹部を設けて排出通気路を形成することができる。また、排出通気路は、容器内部側の吸入口から容器外部側の排出口に向かい窄まるように形成することが好ましい。排出通気路を容器内部から容器外部に向かう凹部とすることにより、蒸気を容器外部に排出しやすくなる。また、吸入口から排出口に向けて窄まるように形成することにより、排出口を小さくして埃などの異物を容器内部に侵入しにくくすることができる。 In the packaging container of the above embodiment, a concave portion extending from the inside of the container to the outside of the container can be provided in the fitting portion or the fitted portion to form a discharge ventilation path. Further, it is preferable that the exhaust air passage narrows from the inlet on the inside of the container to the outlet on the outside of the container. By making the discharge air passage a concave portion extending from the inside of the container to the outside of the container, steam can be easily discharged to the outside of the container. Furthermore, by forming the container so that it narrows from the suction port toward the discharge port, the discharge port can be made smaller to make it difficult for foreign matter such as dust to enter the inside of the container.

上記形態の包装用容器は、連結通気路を、容器全周に渡り設けることができる。これにより、蒸気が全周に渡り分散され、大量の蒸気を排出しやすくなる。 In the packaging container of the above configuration, a connecting air passage can be provided all around the container. This allows the steam to be dispersed over the entire circumference, making it easier to discharge a large amount of steam.

The packaging container 1 stores foodstuffs and the like in storage portions 25a and 25b, covers the opening 23 of the container body 2 with the lid 3, and internally fits the fitting portion 24 and the fitted portion 32. By matching them together, the lid can be closed.
At this time, a connecting air passage 5 and an exhaust air passage 4 are formed between the fitting part 24 and the fitted part 32, as shown in FIG.

食料品などを収容して閉蓋したままの状態で、包装用容器1を電子レンジに入れて加熱すると、大量の蒸気が発生する。容器内部の蒸気は、図3の矢印に示すように、吸入口41から排気通気路4に流れ込み、一部の蒸気はその排気通気路4を流れて排気口42から容器外部に排出され、他の蒸気は、交差する連結通気路5に流れ込み、他の排気通気路4の排出口5から容器外部に排出される。 When the packaging container 1 containing foodstuffs and the like is placed in a microwave oven and heated with the lid closed, a large amount of steam is generated. The steam inside the container flows from the inlet 41 into the exhaust air passage 4 as shown by the arrow in FIG. The steam flows into the intersecting connecting air passages 5 and is discharged to the outside of the container from the outlet 5 of the other exhaust air passage 4.

このように、包装用容器1は、容器内部に大量の蒸気が発生したとしても、排出通気路4に流れ込んだ蒸気が連結通気路5により他の排出通気路4に分散されるため、一定箇所に圧力が集中して、蓋体3が押し上げられ、飛散させられることがなく、大量の蒸気をスムーズに排出することができる。 In this way, even if a large amount of steam is generated inside the container, the packaging container 1 can be used at certain locations because the steam that has flowed into the exhaust air passage 4 is dispersed to other exhaust air passages 4 by the connecting air passage 5. A large amount of steam can be smoothly discharged without the pressure being concentrated and the lid body 3 being pushed up and scattered.

また、排出口42を小さくすることもでき、これにより、埃や虫などの異物を容器内部に侵入させにくくすることができる。 Furthermore, the discharge port 42 can be made smaller, thereby making it difficult for foreign substances such as dust and insects to enter the inside of the container.

本実施形態では、嵌合部24及び被嵌合部32ともに折れ筋26,33を設けて連結通気路5を形成したが、図6に示すように、嵌合部24を垂直乃至傾斜面とし、被嵌合部32のみに折れ筋33を設けて連結通気路5としてもよく、また、図7に示すように、被嵌合部32を垂直乃至傾斜面とし、嵌合部24のみに折れ筋26を設けて連結通気路5としてもよい。 In this embodiment, the connecting air passage 5 is formed by providing the bending lines 26 and 33 in both the fitting part 24 and the fitted part 32, but as shown in FIG. , the connecting air passage 5 may be formed by providing a bend line 33 only on the fitted part 32, or, as shown in FIG. The connecting air passage 5 may be formed by providing the striations 26.

また、本実施形態では、排気通気路4を、被嵌合部32及びフランジ部34に形成したが、図8に示すように、被嵌合部32のみを角溝状に凹ませて上下方向に延びる排気通気路4としてもよい。蒸気を排出する際は、排気通気路4に流入した蒸気の圧力によりフランジ部34及びスカート部35を押し上げて容器外部に蒸気を排出することができる。これにより、排出口42が、常時はフランジ部34により閉じられているので、より一層異物の侵入を防ぐことができる。 Further, in this embodiment, the exhaust air passage 4 is formed in the fitted part 32 and the flange part 34, but as shown in FIG. It may also be an exhaust air passage 4 extending to . When discharging steam, the pressure of the steam flowing into the exhaust air passage 4 pushes up the flange portion 34 and the skirt portion 35, allowing the steam to be discharged to the outside of the container. As a result, since the discharge port 42 is normally closed by the flange portion 34, it is possible to further prevent foreign matter from entering.

さらに、排気通気路4を、嵌合部24に容器内部から容器外部に向かう凹部を設けて形成してもよい。排気通気路4は、嵌合部24、被嵌合部32のいずれかに設けてあればよく、両方に設けてもよい。排気通気路4を嵌合部24、被嵌合部32の両方に設けた場合は、蓋体3を容器本体2に嵌合した際に、両排気通気路4が重なるようにするのが好ましい。 Furthermore, the exhaust air passage 4 may be formed by providing a recessed portion in the fitting portion 24 extending from the inside of the container to the outside of the container. The exhaust air passage 4 may be provided in either the fitting part 24 or the fitted part 32, or may be provided in both. When the exhaust air passage 4 is provided in both the fitting part 24 and the fitted part 32, it is preferable that both the exhaust air passages 4 overlap when the lid 3 is fitted to the container body 2. .

上記実施形態の構成態様は、本発明を限定するものとして挙げたものではなく、技術目的を共通にするかぎり変更は可能であり、本発明はそのような変更を含むものである。 The configuration aspects of the embodiments described above are not listed as limiting the present invention, but can be modified as long as the technical purpose is shared, and the present invention includes such modifications.
