しかしながら、前述した特許文献1〜3に記載された従来技術には、次のような問題があった。   However, the conventional techniques described in Patent Documents 1 to 3 described above have the following problems.

特許文献1に記載された保冷容器は、真空予冷のみの場合には有効であるが、通常の容器としては空気の流入があり、雰囲気温度が高い場合には容器内部の温度が上昇し易い問題がある。   The cold storage container described in Patent Document 1 is effective when only vacuum precooling is used, but as a normal container, there is an inflow of air, and when the ambient temperature is high, the temperature inside the container is likely to rise. There is.

特許文献2に記載された保冷容器は、流入した空気が蓄冷材と接触して容器内に入る構造になっているが、時間の経過とともに蓄冷材の温度が上昇すると保冷効果が薄れる問題がある。   The cold insulation container described in Patent Document 2 has a structure in which the inflowed air comes into contact with the cold storage material and enters the container. However, when the temperature of the cold storage material rises with time, there is a problem that the cold insulation effect is diminished. .

特許文献3に記載された搬送容器は、内容物を冷やした後、蓋を被せる作業を行わなければならず、作業が煩雑になる問題がある。   The transport container described in Patent Document 3 has a problem that the work needs to be performed after the contents are cooled, and then the cover is put on the cover.

このように、従来の保冷容器にあっては、容器本体に蓋体を被せた状態で、真空予冷と冷蔵庫内冷却の両方に使用する場合に改善すべき点があった。   As described above, the conventional cold storage container has a point to be improved when it is used for both the vacuum pre-cooling and the refrigerator cooling with the container body covered with the lid.

本発明は前記事情に鑑みてなされ、同じ容器で真空予冷容器と冷蔵庫内冷却容器を兼用でき、優れた保冷性能を持った保冷容器の提供を目的とする。   This invention is made | formed in view of the said situation, and it aims at provision of the cold storage container which can use a vacuum pre-cooling container and the refrigerator internal cooling container with the same container, and has the outstanding cold preservation performance.

前記目的を達成するため、本発明は、合成樹脂発泡体製の容器本体と、該容器本体の開口に被せる通気口付きの蓋体と、該蓋体の上面側に、前記通気口を塞ぐ位置と前記通気口が開口する位置との間をスライド可能でかつ前記蓋体に対して着脱可能に設けられた小蓋とを有してなるとともに、前記小蓋の表裏面のいずれかに、小蓋が通気口を塞ぐ位置にある時に容器内部と外部を連通する通気手段が設けられたことを特徴とする保冷容器を提供する。   In order to achieve the above object, the present invention provides a container body made of a synthetic resin foam, a lid body with a vent hole covering the opening of the container body, and a position where the vent hole is closed on the upper surface side of the lid body And a small lid that is slidable between the opening and the position where the vent opens, and is detachably attached to the lid body. Provided is a cold insulation container provided with a ventilation means for communicating between the inside and outside of the container when the lid is in a position to close the ventilation hole.

本発明の保冷容器において、前記通気手段として、小蓋の表裏面のいずれかの周縁部に通気凹溝が設けられたことが好ましい。   In the cold insulation container of the present invention, it is preferable that a ventilation ditch is provided in the peripheral edge of either of the front and back surfaces of the small lid as the ventilation means.

本発明の保冷容器において、前記蓋体の上面側に、前記通気口に隣接して前記小蓋をスライドさせる摺動用凹部が設けられたことが好ましい。   In the cold insulation container of the present invention, it is preferable that a sliding recess for sliding the small lid is provided adjacent to the vent on the upper surface side of the lid.

本発明の保冷容器において、前記摺動用凹部の周縁に、前記小蓋の周縁と接する係合凹部が設けられるとともに、前記小蓋の周縁に前記係合凹部と係合する突起が設けられたことが好ましい。   In the cold storage container of the present invention, an engagement recess that is in contact with the periphery of the small lid is provided on the periphery of the sliding recess, and a protrusion that is engaged with the engagement recess is provided on the periphery of the small lid. Is preferred.

本発明の保冷容器において、前記摺動用凹部の周縁に、前記小蓋の係合凹部と係合して該小蓋を上方側に向けてガイドし蓋体から離脱させるガイド凹部が設けられたことが好ましい。   In the cold insulation container of the present invention, a guide recess is provided on the periphery of the sliding recess to engage with the engagement recess of the small lid so that the small lid is guided upward and separated from the lid. Is preferred.

本発明の保冷容器は、容器本体の開口に被せる通気口付きの蓋体の上面側に、通気口を塞ぐ位置と通気口が開口する位置との間をスライド可能でかつ蓋体に対して着脱可能に小蓋を設けるとともに、この小蓋の表裏面のいずれかに、小蓋が通気口を塞ぐ位置にある時に容器内部と外部を連通する通気手段を設けた構成としたので、次の(A)、(B)の通り、真空予冷する場合と冷蔵庫内冷却する場合とで小蓋の表裏を代えて使用することにより、真空予冷容器と冷蔵庫内冷却容器を兼用でき、優れた保冷性能を持った保冷容器を提供することができる。
(A)真空予冷する場合には、小蓋を通気手段のある側を下向きにして蓋体に取り付け、通気口を塞ぐ位置にスライドさせる。小蓋で通気口を塞いでも、通気手段によって容器内部と外部が連通しているので、真空予冷によって容器内部を冷やすことができる。
(B)冷蔵庫内冷却する場合には、小蓋を通気手段のある側を上向きにして蓋体に取り付け、冷蔵庫内では通気口を開く位置にスライドさせる。これにより通気口を通して冷気が容器内部に入り、容器内部を冷やすことができる。庫外では小蓋を通気口を塞ぐ位置にスライドさせることで、外気が入り込み難くなり、高い保冷性を維持できる。
The cold storage container of the present invention is slidable between the position where the vent is closed and the position where the vent opens, on the upper surface side of the lid with the vent covering the opening of the container main body, and is detachable from the lid. Since a small lid is provided as possible, and on either the front or back surface of this small lid, when the small lid is in a position to close the vent, a ventilation means for communicating the inside and outside of the container is provided. As shown in (A) and (B), the front and back of the small lid can be used differently for pre-vacuum cooling and cooling in the refrigerator, so that both the vacuum pre-cooling container and the cooling container in the refrigerator can be used. A cold storage container can be provided.
(A) In the case of vacuum precooling, the small lid is attached to the lid with the side having the ventilation means facing downward, and is slid to a position where the vent is closed. Even if the vent is closed with a small lid, the inside of the container communicates with the outside by the ventilation means, so that the inside of the container can be cooled by vacuum precooling.
(B) When cooling in the refrigerator, the small lid is attached to the lid with the side having the ventilation means facing upward, and is slid to the position where the vent is opened in the refrigerator. Thereby, cold air enters the inside of the container through the vent, and the inside of the container can be cooled. By sliding the small lid to a position that closes the vents outside the refrigerator, it becomes difficult for outside air to enter and high cold insulation can be maintained.

本実施形態において、保冷容器1は、合成樹脂発泡体製の容器本体2と、この容器本体2の開口2Aに被せる通気口4付きの蓋体3と、この蓋体3の上面側に、通気口4を塞ぐ位置と通気口4が開口する位置との間をスライド可能でかつ蓋体3に対して着脱可能に設けられた小蓋5とを有してなるとともに、小蓋5の表裏面のいずれかの周縁部に一対の通気凹溝6(通気手段)が設けられたことを特徴としている。   In this embodiment, the cold insulation container 1 includes a container body 2 made of a synthetic resin foam, a lid 3 with a vent 4 that covers the opening 2A of the container body 2, and an air vent on the upper surface side of the lid 3. It has a small lid 5 that is slidable between a position for closing the opening 4 and a position for opening the vent hole 4 and is detachably attached to the lid 3. A pair of ventilation grooves 6 (ventilating means) is provided in any one of the peripheral portions.

本実施形態において、容器本体2、蓋体3及び小蓋5は、それぞれ同種の合成樹脂発泡体で構成されている。この合成樹脂発泡体としては、例えば、ポリエチレン系樹脂発泡体、ポリプロピレン系樹脂発泡体、ポリスチレン系樹脂発泡体、ポリエチレンテレフタレート(PET)系樹脂発泡体などの熱可塑性樹脂発泡体が用いられ、特に、ポリスチレン系樹脂発泡体が好ましい。また、合成樹脂発泡体の密度は密度12〜210kg/mの範囲が好ましい。なお、本発明は本例示に限定されず、非発泡の熱可塑性樹脂フィルム又はシートを合成樹脂発泡体に積層した複合成形体で形成したり、蓋体3及び小蓋5の一方または両方を他の材料、例えば非発泡の熱可塑性樹脂成形体で形成しても良い。 In the present embodiment, the container main body 2, the lid 3 and the small lid 5 are each made of the same type of synthetic resin foam. As this synthetic resin foam, for example, thermoplastic resin foam such as polyethylene resin foam, polypropylene resin foam, polystyrene resin foam, polyethylene terephthalate (PET) resin foam, etc. are used. Polystyrene resin foam is preferred. The density of the synthetic resin foam is preferably in the range of 12 to 210 kg / m 3 . In addition, this invention is not limited to this illustration, It forms with the composite molded object which laminated | stacked the non-foamed thermoplastic resin film or sheet | seat on the synthetic resin foam, and one or both of the cover body 3 and the small cover 5 are others. You may form with the material of this, for example, a non-foamed thermoplastic resin molding.

本実施形態において、容器本体2の形状は平面視四角形であり、その一辺の側壁部を底部近傍まで切欠き、前方と上方に開口2Aを拡張した箱状とし、一方、蓋体3はその開口2Aを塞ぐように、側面視逆L字状として構成しているが、容器本体2と蓋体3の形状は本例示に限定されず、種々の形状の容器本体とその開口に被せる蓋体の組み合わせを用いることができる。   In this embodiment, the shape of the container main body 2 is a quadrangle in plan view, the side wall portion of one side thereof is cut out to the vicinity of the bottom portion, and the opening 2A is extended forward and upward, while the lid 3 has its opening. Although it is configured as an inverted L shape in side view so as to close 2A, the shapes of the container body 2 and the lid 3 are not limited to this example, and various shapes of the container body and lids covering the openings thereof Combinations can be used.

また本実施形態において、蓋体3に穿設する通気口4は、通気口4を開口した状態で冷蔵庫内冷却する場合に通気口4を通して冷気が十分に流入できればよく、その形状、寸法等は限定されない。また、保冷容器1の形状や大きさに応じて、通気口4を複数個設けることもできる。さらに、小蓋5の形状及び寸法は、通気口4を塞ぐことができればよく、通気口4の形状や寸法に応じて適宜設定可能である。   Further, in the present embodiment, the vent hole 4 formed in the lid 3 is sufficient if cold air can sufficiently flow through the vent hole 4 when cooling in the refrigerator with the vent hole 4 opened. It is not limited. Further, a plurality of vent holes 4 can be provided according to the shape and size of the cold container 1. Furthermore, the shape and dimensions of the small lid 5 are only required to be able to block the vent hole 4, and can be set as appropriate according to the shape and dimensions of the vent hole 4.

本実施形態において、蓋体3の上面側には、通気口4に隣接して小蓋5をスライドさせるための摺動用凹部7が設けられている。また、摺動用凹部7の周縁には、小蓋5の周縁と接する係合凹部8が設けられるとともに、小蓋5の周縁には係合凹部8と係合する突起9が設けられている。さらに、摺動用凹部7の周縁には、小蓋5の係合凹部8と係合して小蓋5を上方側に向けてガイドし、蓋体3から離脱させるためのガイド凹部10が設けられている。   In the present embodiment, a sliding recess 7 for sliding the small lid 5 adjacent to the vent 4 is provided on the upper surface side of the lid 3. In addition, an engagement recess 8 that contacts the periphery of the small lid 5 is provided on the periphery of the sliding recess 7, and a protrusion 9 that engages with the engagement recess 8 is provided on the periphery of the small lid 5. Further, a guide recess 10 for engaging the engagement recess 8 of the small lid 5 to guide the small lid 5 upward and detaching from the lid 3 is provided on the periphery of the sliding recess 7. ing.

図2は、本実施形態の保冷容器1を冷蔵庫内冷却容器として使用する場合に、通気口4を塞ぐ位置に小蓋5をスライドさせた状態を示している。冷蔵庫内冷却容器として使用する場合には、小蓋5の通気凹溝6がある面を上向きにして蓋体3に取り付ける。なお、本例示では通気凹溝6として、小蓋5の両側中央に対向して一対の通気凹溝6を設けた構成としているが、通気凹溝6の配置位置、形成個数、形状等は本例示に限定されるものではなく、小蓋5の形状等に応じて適宜設定可能である。   FIG. 2 shows a state in which the small lid 5 is slid to a position where the vent 4 is closed when the cold storage container 1 of the present embodiment is used as a refrigerator cooling container. When used as a refrigerator cooling container, the small lid 5 is attached to the lid 3 with the surface with the vent groove 6 facing upward. In this example, the ventilation groove 6 has a configuration in which a pair of ventilation grooves 6 are provided opposite to the center of both sides of the small lid 5. It is not limited to the illustration, and can be set as appropriate according to the shape of the small lid 5 and the like.

この図2に示す状態では、通気口4が小蓋5によって塞がれ、容器本体1は気密性が高い状態になっている。保冷容器1を冷蔵庫内に入れて冷却後、庫外に出す場合には、図2に示すように通気口4を小蓋5によって塞ぐことで、外気が容器内に浸入しにくくなり、高い保冷性が得られる。   In the state shown in FIG. 2, the vent 4 is closed by the small lid 5, and the container main body 1 is in a highly airtight state. When the cold storage container 1 is put into the refrigerator and cooled and then taken out, the vent 4 is closed by a small lid 5 as shown in FIG. Sex is obtained.

図3は、同じく保冷容器1を冷蔵庫内冷却容器として使用する場合に、小蓋5を中間位置にスライドさせた状態を示している。この状態では、通気口4がほぼ半分開口した状態となっている。この状態では、小蓋5の周縁に形成された突起9(図11参照)がガイド凹部10(図9等参照)に入り、該突起9を上方に向けてガイドし、これに沿って小蓋5を引き上げることで、蓋体3から小蓋5を取り外すことができる。取り外した小蓋5は、必要に応じて表裏面を取り替えた後、その突起9をガイド凹部10に挿入し、蓋体3に向けて押し下げることで、簡単に装着することができる。   FIG. 3 shows a state in which the small lid 5 is slid to the intermediate position when the cold container 1 is used as the refrigerator cooling container. In this state, the vent hole 4 is almost half open. In this state, the projection 9 (see FIG. 11) formed on the periphery of the small lid 5 enters the guide recess 10 (see FIG. 9 and the like), guides the projection 9 upward, and along the small lid along this By pulling up 5, the small lid 5 can be removed from the lid 3. The removed small lid 5 can be easily mounted by replacing the front and back surfaces as necessary and then inserting the projection 9 into the guide recess 10 and pushing it down toward the lid 3.

図4は、同じく保冷容器1を冷蔵庫内冷却容器として使用する場合に、小蓋5を通気口4が開口する位置にスライドさせた状態を示している。この状態では、通気口4が大きく開口するため、この保冷容器1を冷蔵庫内冷却する際に、冷蔵庫内の冷気がこの通気口4を通して効率よく流入し、収容物を冷却することができる。冷却後、保冷容器1を庫外に搬出する際には、小蓋5を図2に示すように通気口4を塞ぐ位置にスライドさせることで、簡単に保冷性を高めることができる。   FIG. 4 shows a state in which the small lid 5 is slid to a position where the vent 4 is opened when the cold storage container 1 is used as a cooling container in the refrigerator. In this state, since the vent 4 is greatly opened, when the cold container 1 is cooled in the refrigerator, the cool air in the refrigerator can efficiently flow through the vent 4 and cool the contents. After cooling, when carrying out the cold storage container 1 out of the refrigerator, the cold insulation can be easily improved by sliding the small lid 5 to a position where the vent 4 is closed as shown in FIG.

図5は、保冷容器1を真空予冷容器として使用する場合に、小蓋5を中間位置にスライドさせた状態を示している。前述した通り、図3に示す状態において、小蓋5を中間位置にスライドさせ、小蓋5を引き上げることで、蓋体3から小蓋5を取り外し、通気凹溝6が設けられた側を下向き(蓋体3側)とした後、この小蓋5を蓋体3に取り付けることで、図5に示すように簡単に真空予冷容器としての適用変更が可能となる。   FIG. 5 shows a state in which the small lid 5 is slid to an intermediate position when the cold container 1 is used as a vacuum precooling container. As described above, in the state shown in FIG. 3, the small lid 5 is slid to the intermediate position, and the small lid 5 is pulled up to remove the small lid 5 from the lid 3, and the side on which the ventilation groove 6 is provided faces downward. After changing to (the lid 3 side), by attaching this small lid 5 to the lid 3, the application change as a vacuum precooling container can be easily performed as shown in FIG.

図6は、同じく保冷容器1を真空予冷容器として使用する場合に、小蓋5を通気口4を塞ぐ位置にスライドさせた状態を示している。この状態では、小蓋5によって通気口4が塞がれるが、小蓋5に設けられた通気凹溝6によって容器内部と外部とが連通している。このように真空予冷の際に、容器内部の空気が通気凹溝6を通して外部に抜け出すことで、真空予冷の際に小蓋5で通気口4を塞いであっても、容器内圧が真空排気している外部より高くなって蓋体3が外れることがなく、真空予冷を行うことができる。また、通気凹溝6が設けられた側を下向きとした小蓋5によって通気口4を塞いでおけば、容器内と外部とが連通している部分は通気凹溝6の僅かな隙間だけなので、容器内圧と外気圧とが等しい大気圧雰囲気下では外気が容器内にほとんど流入せず、従って冷却後に保冷容器1を庫外に搬出しても、保冷性が劣化することはほとんどない。   FIG. 6 shows a state in which the small lid 5 is slid to a position where the vent 4 is closed when the cold container 1 is used as a vacuum precooling container. In this state, the vent 4 is closed by the small lid 5, but the inside and outside of the container communicate with each other through the vent groove 6 provided in the small lid 5. As described above, the air inside the container escapes to the outside through the vent groove 6 during the vacuum precooling, so that the internal pressure of the container is evacuated even when the vent 4 is closed with the small lid 5 during the vacuum precooling. Therefore, the cover 3 is not removed from the outside, and vacuum precooling can be performed. If the vent 4 is closed by the small lid 5 with the vent groove 6 facing down, the portion where the inside and outside of the container communicate with each other is only a slight gap in the vent groove 6. In an atmospheric pressure atmosphere in which the internal pressure of the container is equal to the external atmospheric pressure, the external air hardly flows into the container. Therefore, even if the cold insulation container 1 is taken out after cooling, the cold insulation performance is hardly deteriorated.

図7は、図5及び図6と同じく保冷容器1を真空予冷容器として使用する場合に、小蓋5を通気口4を開口する位置にスライドさせた状態を示している。   FIG. 7 shows a state in which the small lid 5 is slid to the position where the vent 4 is opened when the cold container 1 is used as a vacuum precooling container as in FIGS. 5 and 6.

図8は、保冷容器1を冷蔵庫内冷却容器として使用する場合に、小蓋5を通気口4が開口する位置にスライドさせた状態(図4参照)にある保冷容器1の上に、別な保冷容器1を段積みした状態を示している。小蓋5の通気凹溝6は、上向きになっている。保冷容器1の容器本体2底面側には、段積みした際に直下の保冷容器1の蓋体3上面の摺動用凹部7と容器本体2底面とが接触しないように脚部となる凸部を設けておくことが望ましい。このように構成することで、保冷容器1を段積みしても、上下の保冷容器1間の隙間及び通気口4を通って、容器内部に冷気が流入し、容器内部が冷却される。   FIG. 8 shows another example in which the small lid 5 is slid to a position where the vent 4 is opened (see FIG. 4) when the cold container 1 is used as a refrigerator cooling container. The state where the cold storage containers 1 are stacked is shown. The vent groove 6 of the small lid 5 is directed upward. On the bottom surface side of the container main body 2 of the cold insulation container 1, a convex portion serving as a leg is provided so that the sliding concave portion 7 on the upper surface of the lid 3 of the cold storage container 1 immediately below and the bottom surface of the container main body 2 do not contact when stacked. It is desirable to have it. With this configuration, even if the cold storage containers 1 are stacked, cold air flows into the containers through the gaps between the upper and lower cold storage containers 1 and the vents 4, and the interior of the containers is cooled.

図8の例示では、蓋体3の摺動用凹部7の通気口4部分に長丸形状の係合凹部8が設けられ、さらに摺動用凹部7の中央部には蓋体3の上面に達するガイド凹部10が設けられている。一方、小蓋5の周縁には、これらの係合凹部8及びガイド凹部10に係合する突起9(図11参照)が設けられている。   In the example of FIG. 8, an oblong engaging recess 8 is provided in the vent 4 portion of the sliding recess 7 of the lid 3, and a guide reaching the upper surface of the lid 3 is provided at the center of the sliding recess 7. A recess 10 is provided. On the other hand, a projection 9 (see FIG. 11) that engages with the engaging recess 8 and the guide recess 10 is provided on the periphery of the small lid 5.

図9は、保冷容器1を冷蔵庫内冷却容器として使用する場合に、通気口4を塞ぐ位置に小蓋5をスライドさせた状態(図2参照)にある保冷容器1の上に、別な保冷容器1を段積みした状態を示している。小蓋5の通気凹溝6は、上向きになっている。冷蔵庫内冷却する場合、保冷容器1の小蓋5は図8に示す通り、通気口4が開口する位置としているが、冷却後に保冷容器1を庫外に搬出する場合には、図9に示すように通気口4を塞ぐ位置に小蓋5をスライドさせる。この後、その上に別な保冷容器1を段積みすることができる。図9の例示では、蓋体3の通気口4と反対側の摺動用凹部7に、横長で一端側がガイド凹部10につながる係合凹部8が設けられている。   FIG. 9 shows another cold insulation on the cold insulation container 1 in a state where the small lid 5 is slid to a position for closing the vent hole 4 (see FIG. 2) when the cold insulation container 1 is used as a cooling container in the refrigerator. A state in which the containers 1 are stacked is shown. The vent groove 6 of the small lid 5 is directed upward. When cooling in the refrigerator, the small lid 5 of the cold insulation container 1 is at a position where the vent 4 is opened as shown in FIG. 8, but when the cold insulation container 1 is carried out of the refrigerator after cooling, it is shown in FIG. Thus, the small lid 5 is slid to a position where the vent hole 4 is closed. Then, another cold storage container 1 can be stacked on it. In the illustration of FIG. 9, an engagement recess 8 that is horizontally long and has one end connected to the guide recess 10 is provided in the sliding recess 7 on the side opposite to the vent 4 of the lid 3.

図10は、保冷容器1を真空予冷容器として使用する場合に、小蓋5を通気口4を塞ぐ位置にスライドさせた状態(図6参照)にある保冷容器1の上に、別な保冷容器1を段積みした状態を示している。小蓋5の通気凹溝6は、下向きになっており、この通気凹溝6を通して容器内部と外部とが連通している。   FIG. 10 shows another cold storage container placed on the cold storage container 1 in a state where the small lid 5 is slid to a position where the vent 4 is closed (see FIG. 6) when the cold storage container 1 is used as a vacuum precooling container. The state where 1 is stacked is shown. The vent groove 6 of the small lid 5 faces downward, and the inside and outside of the container communicate with each other through the vent groove 6.

図11は、蓋体3側の係合凹部8と小蓋5の周縁に設けた突起9との係合状態を示す要部断面図である。なお、本例示では蓋体3側を凹部(係合凹部8)とし、小蓋5側に突起9を設け、この係合凹部8に突起9が摺動可能に係合する構成としたが、小蓋5をスライド可能に取り付ける手段はこれに限定されず、例えば、蓋体3側に、中央で途切れる凸条を水平に設け、小蓋5の周縁に該凸条に係合する凹溝を設けてもよい。この場合には、凸条が途切れた中央部で小蓋5を取り外すことができる。   FIG. 11 is a cross-sectional view of an essential part showing an engagement state between the engagement recess 8 on the lid 3 side and the protrusion 9 provided on the periphery of the small lid 5. In this example, the lid 3 side is a recess (engagement recess 8), a projection 9 is provided on the small lid 5 side, and the projection 9 is slidably engaged with the engagement recess 8. The means for slidably attaching the small lid 5 is not limited to this. For example, a convex strip that is interrupted in the center is provided horizontally on the lid 3 side, and a concave groove that engages with the convex strip is formed on the periphery of the small lid 5. It may be provided. In this case, the small lid 5 can be removed at the center where the ridges are interrupted.

前述したように、本実施形態の保冷容器1は、容器本体2の開口2Aに被せる通気口4付きの蓋体3の上面側に、通気口4を塞ぐ位置と通気口4が開口する位置との間をスライド可能でかつ蓋体3に対して着脱可能に小蓋5を設けるとともに、この小蓋5の表裏面のいずれかに、小蓋5が通気口4を塞ぐ位置にある時に容器内部と外部を連通する通気凹溝6を設けた構成としたので、次の(A)、(B)の通り、真空予冷する場合と冷蔵庫内冷却する場合とで小蓋5の表裏を代えて使用することにより、真空予冷容器と冷蔵庫内冷却容器を兼用でき、優れた保冷性能を持った保冷容器1を提供することができる。
(A)真空予冷する場合には、小蓋5を通気凹溝6のある側を下向きにして蓋体3に取り付け、通気口4を塞ぐ位置にスライドさせる。小蓋5で通気口4を塞いでも、通気凹溝6によって容器内部と外部が連通しているので、真空予冷によって容器内部を冷やすことができる。
(B)冷蔵庫内冷却する場合には、小蓋5を通気凹溝6のある側を上向きにして蓋体3に取り付け、冷蔵庫内では通気口4を開く位置にスライドさせる。これにより通気口4を通して冷気が容器内部に入り、容器内部を冷やすことができる。庫外では小蓋5を通気口4を塞ぐ位置にスライドさせることで、外気が入り込み難くなり、高い保冷性を維持できる。
As described above, the cold insulation container 1 of the present embodiment includes the position where the vent 4 is closed and the position where the vent 4 is opened on the upper surface side of the lid 3 with the vent 4 that covers the opening 2A of the container body 2. The small lid 5 is provided so as to be slidable between the two and the lid 3 so that it can be attached to and detached from the lid 3. Since the structure is provided with a ventilation groove 6 that communicates with the outside, as shown in the following (A) and (B), the front and back of the small lid 5 are used differently when pre-vacuum cooling and cooling in the refrigerator. By doing so, the vacuum precooling container and the refrigerator cooling container can be used together, and the cold insulating container 1 having excellent cold insulating performance can be provided.
(A) In the case of vacuum precooling, the small lid 5 is attached to the lid 3 with the side with the ventilation groove 6 facing downward, and is slid to a position where the ventilation hole 4 is closed. Even when the vent 4 is closed with the small lid 5, the inside of the container communicates with the outside through the vent groove 6, so that the inside of the container can be cooled by vacuum precooling.
(B) When cooling in the refrigerator, the small lid 5 is attached to the lid 3 with the side with the vent groove 6 facing upward, and is slid to the position where the vent 4 is opened in the refrigerator. Thereby, cold air enters the inside of the container through the vent hole 4, and the inside of the container can be cooled. By sliding the small lid 5 to the position where the vent 4 is closed outside the room, it becomes difficult for outside air to enter, and high cold insulation can be maintained.
