【産業上の利用分野】[Industrial applications]

本考案は農産物や水産物等の生鮮食料品、医薬品、菓子、その他冷凍品等のよ うな保冷を必要とする物品を収容する容器に関し、特に冷気導入用の通気孔を具 備し、その通気孔に空気圧利用の伸縮プランジャを有する吸排気弁を設けてなる 容器に関するものである。 The present invention relates to a container for storing articles such as fresh foods such as agricultural products and marine products, medicines, confectionery, and other frozen products that need to be kept cold, and in particular, it is equipped with a ventilation hole for introducing cold air, and the ventilation hole is provided. The present invention relates to a container provided with an intake / exhaust valve having a telescopic plunger that uses air pressure.

【0002】[0002]

【従来の技術】[Prior art]

従来、生鮮食料品、医薬品、冷凍品等の保冷輸送に当っては、品質の維持や遠 隔地への出荷を可能にするため、採取した収穫物または出荷物に予冷処理を施す ことが行われている。 Conventionally, in the cold transport of fresh foods, pharmaceuticals, frozen products, etc., in order to maintain the quality and enable shipment to remote areas, the harvested products or shipped products are pre-cooled. ing.

【0003】 冷却方法としては、例えば物品に砕氷をかけたり、冷水をスプレイする等の方 法が知られているが、近年ダンボール箱等の無蓋容器に内容物をつめて、これに ダンボール箱の孔等より低温の空気(冷風)を吹きつけて予冷する方法や、真空 タンク内に箱づめした内容物を入れ、内容物からの水分蒸発に伴う潜熱冷却を利 用するいわゆる真空冷却法が内容物の品質を損うことなく、しかも冷却が短時間 でできる特色を有することから全国的に普及が進んでいる。As a cooling method, for example, methods such as crushing ice on an article or spraying cold water are known. In recent years, the contents are packed in an open container such as a cardboard box, and the The method includes pre-cooling by blowing cold air (cold air) from holes, etc., and the so-called vacuum cooling method, in which the contents packed in a box are put in a vacuum tank and latent heat cooling is used due to evaporation of water from the contents. It has become popular nationwide because it has the characteristic that it can be cooled in a short time without deteriorating the quality of the product.

【0004】 ところで、内容物を収容する容器としては、通例、ダンボール箱や発泡樹脂製 容器が用いられているが、これらに内容物を収容し予冷した後内容物が外気温に さらされるのを防止するために蓋をかぶせ、梱包して出荷する方法が広く採用さ れている。しかし、このような方法では予冷処理のため容器を無蓋にして予冷庫 に入れ、予冷後予冷庫より取出して保冷のため蓋をかぶせ、更にバンド掛けする ので多くの労力が必要であった。そこで容器に蓋をしたまま内容物の真空予冷や 通風予冷等の予冷処理が効率良く行え、かつ予冷処理後の梱包に労力を要しない で保冷輸送が可能な容器の開発が期待されていた。By the way, as a container for containing the contents, a cardboard box or a foamed resin container is usually used. However, after the contents are contained and pre-cooled, the contents are exposed to the outside temperature. To prevent this, a method of covering with a lid and packing and shipping is widely adopted. However, such a method requires a lot of labor because the container is put in a pre-cooling box without a lid for the pre-cooling process, taken out from the pre-cooling box after being pre-cooled, covered with a lid for keeping cold, and further banded. Therefore, it was expected to develop a container that can efficiently perform pre-cooling such as vacuum pre-cooling and ventilation pre-cooling with the lid on the container and that can be transported by cold storage without labor for packaging after pre-cooling.

【0005】 かかる要望に応えるものとしては、例えば実開昭60−92978号公報に示 されるとおり、蓋の隅部に切欠部を設けると共に、この切欠部に嵌め外し自在の 小蓋を取付けるようにしてなる発泡プラスチック製容器が提案されている。In order to meet such a demand, for example, as disclosed in Japanese Utility Model Laid-Open No. 60-92978, notches are provided at the corners of the lid, and a small lid which can be fitted into and removed from the notches is attached. A container made of foamed plastic has been proposed.

【0006】[0006]

【考案が解決しようとする問題点】[Problems to be solved by the device]

しかしながら、蓋の隅部に切欠部を設け、これに嵌め外し自在の小蓋を具備し た保冷容器にあっては、予冷処理前に小蓋を外し、予冷処理後に小蓋を閉じなけ ればならない。すなわち、小蓋を外せば蓋をしたまま予冷処理を行うことが可能 であるが、予冷庫より取出す場合は切欠部に小蓋を手作業で再度取付けて封鎖し ないと高温外気が侵入して容器内部が昇温してしまう危険があったのである。こ のように従来の容器は予冷処理の前後において、いちいち小蓋を嵌め外しするの で著しく繁雑な手数を要し、そのため不注意や誤操作で小蓋を閉じたまま、ある いは開けたまま放置される危険を有し、冷却後容器を自動的に密封することがで きない構造であった。 However, in the case of a cold insulation container provided with a notch in the corner of the lid and a small lid that can be fitted into and removed from the lid, the small lid must be removed before the precooling treatment and closed after the precooling treatment. I won't. In other words, if the small lid is removed, it is possible to perform the pre-cooling process with the lid on.However, when removing from the pre-cooling cabinet, high temperature outside air will enter unless the small lid is manually reattached to the notch and closed. There was a danger that the temperature inside the container would rise. As described above, the conventional container requires a remarkably complicated work since the small lid is fitted and removed before and after the pre-cooling treatment, and therefore the small lid is closed or left open due to carelessness or erroneous operation. The structure had the risk of being left unattended and the container could not be automatically sealed after cooling.

【0007】 本考案は上記のような問題点を解決するものであり、蓋をしたまま内容物の予 冷処理を効率よく行え、予冷終了後は容器を自動的に密封して容器内部を外気温 から保護できるようにした保冷容器を提供することを目的としている。The present invention solves the above-mentioned problems, and efficiently precools the contents with the lid kept on, and after the precooling is completed, the container is automatically sealed to remove the inside of the container. The purpose is to provide a cool container that can be protected from the temperature.

【問題点を解決するための手段】[Means for solving problems]

上記の目的を達成するため、本考案は容器本体の側壁部または該側壁部の適所 に設ける横蓋に深さ方向にのびる吸排気兼用の通気孔を設けて、該通気孔内に塞 止部を設け、この塞止部上にこれを開け閉めできる球体を配設すると共に、前記 通気孔の下端に外部連通口を設け、また前記塞止部をはさんで外部連通口とは反 対側の位置に、容器内部と連通する連絡口を設けた容器であって、前記通気孔に 設ける塞止部下方位置に、大気圧下では圧縮弾性変形してその長さを見かけ上、 最小長さまで縮小し、大気圧より減圧した状態ではその長さを伸ばして前記球体 を突き上げて前記塞止部を開閉し得る空気圧利用の伸縮プランジャを通気孔との 間に空隙を保って同心的に配置することにより、目的とする吸排気弁付保冷容器 を得るようにしたものである。 In order to achieve the above-mentioned object, the present invention provides a ventilation hole for intake / exhaust extending in the depth direction in a side wall portion of a container body or a lateral lid provided at an appropriate position of the side wall portion, and a blocking portion is provided in the ventilation hole. A sphere that can be opened and closed is provided on this blocking part, an external communication port is provided at the lower end of the ventilation hole, and the opposite side of the external communication port is provided across the blocking part. Is a container having a communication port that communicates with the inside of the container, and is compressed elastically deformed under atmospheric pressure at a position below the blocking part provided in the vent hole, and apparently its length reaches the minimum length. When it is reduced and depressurized from atmospheric pressure, its length is extended and the sphere is pushed up to open and close the blocking part. An air pressure expandable plunger is concentrically arranged with a space between it and the vent hole. In order to obtain the desired cold storage container with intake and exhaust valves. It is intended.

【実施例】【Example】

次に添付図面に基づき、本考案を具体的に説明する。図1は例えばスチレン系 の発泡プラスチックのごとき断熱材料を用いて作られた保冷容器本体1と、容器 本体に対し着脱自在に形成された前記本体と同効の断熱材料より作られた上蓋2 を示す斜視図である。図示の上蓋2は、容器本体に対し印篭蓋形式で嵌合するよ うになっている。 Next, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a cold-insulating container body 1 made of a heat insulating material such as styrene foam plastic, and an upper lid 2 made of a heat insulating material having the same effect as the body detachably formed on the container body. It is a perspective view shown. The illustrated upper lid 2 is adapted to be fitted to the container body in the form of a basket lid.

【0010】 図2は要部構造を示す断面図を示したものである。図示のとおり、容器本体1 の側壁部3の適所に、容器内面側に突出する膨出部3aを容器1の深さ方向に形 成し、またこの膨出部のほぼ中央部に容器深さ方向に、下記の如き吸排気兼用の 通気孔4を垂直状に形成する。この通気孔4は図2に示すように、下方から上方 に向かってその貫通孔の口径が大きくなるように形成されている。そして、この 通気孔4内に段状の塞止部5aと通気孔内に下記のように設けた伸縮式プランジ ャによって上下動しうる球体6aとからなる吸排気弁7aを設けている。FIG. 2 is a sectional view showing the structure of the main part. As shown in the figure, a bulging portion 3a projecting toward the inner surface of the container is formed in a proper position on the side wall portion 3 of the container body 1 in the depth direction of the container 1. In the same direction, the following ventilation holes 4 for both intake and exhaust are formed vertically. As shown in FIG. 2, the vent hole 4 is formed such that the diameter of the through hole increases from the lower side to the upper side. An intake / exhaust valve 7a is provided in the vent hole 4, which is composed of a stepped blocking portion 5a and a spherical body 6a which can be moved up and down by an extendable plunger provided in the vent hole as described below.

【0011】 以下、図2に即して前記吸排気弁の構造と作用を具体的に説明する。本図から も明瞭なように、この考案は、通気孔内に吸排気弁の位置を機械的にダイレクト に規制する空気圧力式伸縮プランジャを配設して、予冷処理の前後の通気孔の開 閉操作を自動的に、かつ確実に行えるようにしたものである。Hereinafter, the structure and operation of the intake / exhaust valve will be specifically described with reference to FIG. As is clear from this figure, this device has an air pressure type telescopic plunger that mechanically directly regulates the position of the intake / exhaust valve in the ventilation hole to open the ventilation hole before and after the pre-cooling process. The closing operation is performed automatically and surely.

【0012】 図面において符号30が空気圧力式伸縮プランジャである。この空気圧力式伸 縮プランジャ30は、プラスチック等の弾性材料によって全体が密閉中空状断面 を有するように形成されている。そして、下部に伸縮可能な蛇腹部31を有し、 上部にボール式吸排気弁を支持する受部32を形成した軸部33が蛇腹部上端か ら垂直に延びている。この空気圧力式伸縮プランジャ30は、図2に示すとおり 吸排気弁7aの下方位置に通気孔4との間に空隙を保って同心的に配置するもの であり、蛇腹部31が大気圧下では圧縮弾性変形してプランジャ全体のストロー ク長さを見かけ上最小長さまで縮小し、吸排気弁7aを塞止部5a上に係止する ように構成されている。またこのプランジャは大気圧よりも減圧された雰囲気下 に放置すると、プランジャ内部の空気が膨張して蛇腹部31が伸び、それにより 軸部33がストロークを伸ばして前記吸排気弁7aを塞止部5aから上動させる ように押し上げることができるように構成されているものである。In the drawings, reference numeral 30 is a pneumatic expansion and contraction plunger. The pneumatic expansion / contraction plunger 30 is formed of an elastic material such as plastic so as to have a closed hollow cross section as a whole. A shaft portion 33 having a bellows portion 31 which is expandable and contractible in the lower portion and a receiving portion 32 for supporting the ball type intake / exhaust valve in the upper portion extends vertically from the upper end of the bellows portion. As shown in FIG. 2, the pneumatic expansion / contraction plunger 30 is arranged concentrically below the intake / exhaust valve 7a with a gap between the vent hole 4 and the bellows portion 31 under atmospheric pressure. It is configured so as to be compressed and elastically deformed to apparently reduce the stroke length of the entire plunger to the minimum length, and to lock the intake / exhaust valve 7a on the blocking portion 5a. When this plunger is left in an atmosphere depressurized below atmospheric pressure, the air inside the plunger expands and the bellows portion 31 expands, whereby the shaft portion 33 extends its stroke and the intake and exhaust valve 7a is blocked. It is configured so that it can be pushed up so as to move upward from 5a.

【0013】 次に本実施例の作用を説明する。まず保冷を必要とする物品(例えば野菜)を 容器本体1内に収納した後、蓋2を容器の開口面に被嵌する。そして、その状態 でこの容器を予冷庫、例えば真空タンク内を真空ポンプで速やかに脱気して、例 えば気圧を4mmHg程度まで下げて保冷物品の水分蒸発を促進して真空冷却処理を 行わせるのである。すなわち、本容器に蓋をし、この容器を真空タンク内に収容 して、大気圧より所要圧力まで真空ポンプで排気すると、排気されるにしたがっ て通気孔内に設置された空気圧力式伸縮プランジャ30の軸部33が伸び、この 軸部上方に設けた受部32が図2に仮想線で示すように球体6aを機械的に直接 押し上げて塞止部5aを開口させる。その結果、容器内部の空気は、通気孔上端 に形成された容器内部との連絡口10を通じて外部連通口8bから確実に排気さ れるから、これにより容器内の内容物は真空冷却することができる。Next, the operation of this embodiment will be described. First, an article (for example, vegetables) that needs to be kept cold is stored in the container body 1, and then the lid 2 is fitted on the opening surface of the container. Then, in this state, the container is pre-cooled, for example, the inside of the vacuum tank is quickly degassed by a vacuum pump, for example, the atmospheric pressure is lowered to about 4 mmHg to accelerate the evaporation of water in the cold-insulated product and perform the vacuum cooling process. Of. That is, when the container is capped, housed in a vacuum tank, and evacuated by a vacuum pump from atmospheric pressure to a required pressure, the air pressure type telescopic plunger installed in the vent hole is exhausted. The shaft portion 33 of 30 extends, and the receiving portion 32 provided above the shaft portion mechanically directly pushes up the spherical body 6a to open the blocking portion 5a, as shown by an imaginary line in FIG. As a result, the air inside the container is surely exhausted from the external communication port 8b through the communication port 10 with the inside of the container formed at the upper end of the vent hole, whereby the contents in the container can be cooled in vacuum. .

【0014】 また真空冷却処理を終え、真空タンク内を大気圧に戻したときは、外部圧力に より前記プランジャ30は変形してその蛇腹部31が縮小する。その場合、まず 球体6aは外部連通孔8bより流入する空気によって浮動して吸排気弁7aは開 いて容器内に空気が流れる。しかしその後、容器内と外部とはいずれもほぼ同圧 力になるので、前記球体6aは塞止部5a上に復帰してこれを閉鎖することにな る。したがって通気孔4は自動的に密閉され外気温から容器内部を保護すること ができるのである。When the vacuum cooling process is completed and the inside of the vacuum tank is returned to the atmospheric pressure, the plunger 30 is deformed by the external pressure and the bellows portion 31 is contracted. In that case, first, the spherical body 6a is floated by the air flowing in from the external communication hole 8b, the intake / exhaust valve 7a is opened, and the air flows into the container. However, after that, since the inside and outside of the container have almost the same pressure, the spherical body 6a returns to above the blocking portion 5a and closes it. Therefore, the vent hole 4 is automatically closed, and the inside of the container can be protected from the outside temperature.

【0015】[0015]

【考案の効果】[Effect of device]

以上述べたように本考案による保冷容器は、真空予冷処理を行う場合において 、容器に蓋をしたまま、または容器を段積みにした状態でも内容物を効率よく真 空冷却することができ、また真空冷却後は、通気孔を自動的に密閉して容器内部 を外気温から保護することができる。したがって、梱包に手数をかけずに保冷輸 送が行える利点がある。 As described above, the cold storage container according to the present invention is capable of efficiently cooling the contents in the air in a vacuum pre-cooling process even when the containers are covered or stacked. After vacuum cooling, the ventilation holes can be automatically sealed to protect the inside of the container from outside temperature. Therefore, there is an advantage that cold storage can be performed without troublesome packing.

【0016】 なお従来、合成樹脂発泡体よりなる容器本体とこれに被嵌される蓋体とからな る保冷容器において、前記の蓋体に容器内外に連通する通気孔を設けると共にそ の通気孔外側に一部を接着し、他の部分を通気孔に対して弾性的に開閉可能にな るようにしたリーフ形の弁体を取付けたもの(例えば実開昭61−132273 号公報参照)が提案されている。この従来例では重要部品であるリーフ弁が予冷 処理時に的確に作動しないことが数多くあり、そのうえ弁体が容器外部に露出し ているので、保冷処理が施された収穫物が生産地から出荷され、各種の流通経路 を経て消費地に到着するまでの間に、外からゴミ等の異物がリーフ弁に付着した り弁座との間にはさまって不具合(故障)を生じやすい。そのうえこの従来例は 容器蓋体に対し別部品である弁体を部分的に接着しかつ露出させて使用する構造 であるため、流通時のハンドリングに伴い人もしくは物との接触が避けられず、 その接触によっては接着部が剥離し、場合によっては弁体そのものがとれてしま うという欠点がある。しかも外観上の見栄えも悪いものであった。本考案は、通 気孔に空気圧利用の伸縮プランジャを有する吸排気弁を設けてなるので、上記し た従来例の欠点を改善することができる。Conventionally, in a cool container comprising a container body made of a synthetic resin foam and a lid fitted to the container body, the lid body is provided with a ventilation hole communicating with the inside and outside of the container and the ventilation hole. One in which a leaf-shaped valve body is attached, one part of which is bonded to the outside and the other part of which is elastically openable and closable with respect to the ventilation hole (for example, see Japanese Utility Model Laid-Open No. 61-132273) Proposed. In this conventional example, the leaf valve, which is an important component, often does not operate properly during precooling, and since the valve element is exposed outside the container, the cold-treated harvested product is shipped from the production site. During the time it arrives at the place of consumption via various distribution channels, foreign matter such as dust is likely to adhere to the leaf valve from the outside or get caught between the leaf valve and the valve seat, causing malfunctions. Moreover, since this conventional example has a structure in which the valve body, which is a separate component, is partially adhered to the container lid and is exposed, it is inevitable to come into contact with people or objects during handling during distribution, Depending on the contact, there is a drawback that the adhesive part peels off and the valve body itself may come off in some cases. Moreover, the appearance was not good. According to the present invention, since the intake and exhaust valve having the expansion and contraction plunger for utilizing the air pressure is provided in the ventilation hole, the above-mentioned drawbacks of the conventional example can be improved.
