図５は本実施形態の吸引手段として電気掃除機だけを用いる場合の図であり、これは前記実施形態と比べ、外蓋（６）は中蓋（２）の位置に配置され、逆止弁付き吸引パイプ（３）が外蓋（６）に図中のように取付けられている。又、ボックス本体（１）は同一で、中蓋（２）と排出部分（５）は不要である。他の部品は同じである。尚、吸引手段（４）の電気掃除機は具備せずに、別に用意すれば良い。 FIG. 5 is a diagram in the case where only a vacuum cleaner is used as the suction means of the present embodiment, which is compared with the previous embodiment, in which the outer lid (6) is arranged at the position of the inner lid (2), and the check valve The attached suction pipe (3) is attached to the outer lid (6) as shown in the figure. Further, the box body (1) is the same, and the inner lid (2) and the discharge part (5) are unnecessary. Other parts are the same. In addition, what is necessary is just to prepare separately, without providing the vacuum cleaner of a suction means (4).
次に本発明品の使用方法について説明する。予めボックス本体（１）の収納部に氷を適宜量入れ、且つ、生鮮食品や生鮮物などを入れて中蓋（２）をして密閉状態にしておく。この時、ボックス本体（１）と中蓋（２）の間にパッキンを取付けておくと良い。次にボックス本体（１）の収納部の空気を外部に排出させて減圧状態にする。この減圧させる場合は、手動式と掃除機によるものとの２通りで行われる。先ず始めに手動式で減圧させる場合について説明する。この場合は、掃除機が身近にない時、つまり、屋外や野外で減圧させる場合である。
先ず作動杆（46）を、ピストン（41）が往復運動するようにセットする。尚、持ち運びする際にはレバー部分が突出しないように、図１に示すように倒されている。このため、図３の図中に示す杆の黒丸位置にピンやボルトなどを挿入してレバー部分と杆とを接続してセットするのである。セット後、レバー部分が図３のように起立するので、それを手で押し、図中の２点鎖線の位置まで倒し、倒れた後は手を離せば、バネの力によって自然に元の位置までレバー部分が戻される。この運動を矢印のように繰返すことにより、ピストン（41）は往復運動し、空気を高圧にしてシリンダー（42）に貯め込むと共に高圧になった空気が排出用チューブ（45）から点線矢印のように逆止弁付き接続パイプ（53）を通過させて排出部分(５)を通過し、外部へ排出（排気）されるのである。この時にはフタ（52）を外しておく。排出を続行すると、ボックス本体（１）の空気が図中の矢印のように吸引用チューブ（44）から吸引されながら排出すると、内部が徐々に減圧されるため、ボックス本体（１）或いは中蓋（２）の外部が若干凹むので、凹み始めた時点で作動杆（46）の操作を止める。この時、凹みで判断するだけでなく、きしむ音が生じた時点で作動杆（46）の操作を止めるようにしても良い。また図示しない減圧計（圧力計）が取付けられている場合には、その目盛を見ながら操作を止めると良い。
その後、筒体（51）の上部にフタ（52）を取付ける。更に外蓋（６）を中蓋（２）の上部に取付ければ減圧させる作業が終了する。
Next, a method for using the product of the present invention will be described. An appropriate amount of ice is put in the storage part of the box body (1) in advance, and fresh food, fresh food, etc. are put therein and the inner lid (2) is put in a sealed state. At this time, it is preferable to attach a packing between the box body (1) and the inner lid (2). Next, the air in the storage part of the box main body (1) is discharged to a reduced pressure state. In the case of reducing the pressure, it is performed in two ways: a manual type and a vacuum cleaner. First, the case where the pressure is reduced manually will be described. In this case, when the vacuum cleaner is not familiar, that is, when the pressure is reduced outdoors or outdoors.
First, the operating rod (46) is set so that the piston (41) reciprocates. In addition, when carrying, it is brought down as shown in FIG. 1 so that the lever portion does not protrude. For this reason, a pin, a bolt, or the like is inserted into the black circle position of the collar shown in FIG. 3, and the lever portion and the collar are connected and set. After setting, the lever part stands as shown in Fig.3. Push it with your hand and tilt it to the position indicated by the two-dot chain line in the figure. The lever part is returned to. By repeating this movement as shown by the arrow, the piston (41) reciprocates and accumulates air in the cylinder (42) at a high pressure, and the high pressure air flows from the discharge tube (45) as shown by the dotted arrow. Then, it passes through the connection pipe (53) with a check valve, passes through the discharge part (5), and is discharged (exhaust) to the outside. At this time, the lid (52) is removed. If the discharge is continued, the air inside the box body (1) is discharged while being sucked from the suction tube (44) as shown by the arrow in the figure. Since the outside of (2) is slightly recessed, the operation of the operating rod (46) is stopped when it begins to be recessed. At this time, the operation of the operating rod (46) may be stopped at the time when a squeak noise is generated, in addition to the determination by the dent. If a pressure gauge (not shown) is attached, the operation should be stopped while looking at the scale.
Thereafter, the lid (52) is attached to the upper part of the cylinder (51). Furthermore, if the outer lid (6) is attached to the upper part of the inner lid (2), the operation of depressurizing is completed.
次に掃除機を使用して減圧させる場合を図５で説明する。先ず掃除機用ホース或いはクリーニング用ホースを、中蓋（２）の底面から突出する逆止弁付き吸引パイプ（３）に挿入させる。この時、逆止弁付き吸引パイプ（３）の外周にアジャスト部材（31）が装着されているので、掃除機用ホース或いはクリーニング用ホースと逆止弁付き吸引パイプ（３）はアジャスト部材（31）によって密接した状態で接続される。その後、掃除機のスイッチを入れて作動させると、ボックス本体（１）内部の空気が吸引されて外部へ排出されるのである。この状態を続行すると、ボックス本体（１）内部が減圧されて、ボックス本体（１）或いは中蓋（２）の外部が若干凹むので、凹み始めた時点又はきしむ音が生じた時点で掃除機を停止させる。これで減圧させる作業が終了する。この場合は、２〜３分前後で減圧状態が得られる。この減圧状態で家や所定の場所まで運搬すれば良い。尚、図１、図３に示す構成のものを用い、掃除機で減圧させる場合は、上記同様に掃除機用ホース或いはクリーニング用ホースを、中蓋（２）の底面から突出する逆止弁付き吸引パイプ（３）に挿入させる。そして掃除機のスイッチを入れて作動させると、ボックス本体（１）内部の空気を吸引し、ボックス本体（１）内部が減圧された後、上記同様に掃除機を停止する。そして、筒体（51）の上部にフタ（52）を取付け、更に外蓋（６）を中蓋（２）の上部に取付ければ減圧作業が終了する。 Next, the case where pressure is reduced using a vacuum cleaner will be described with reference to FIG. First, the vacuum cleaner hose or the cleaning hose is inserted into the suction pipe (3) with a check valve protruding from the bottom surface of the inner lid (2). At this time, since the adjusting member (31) is mounted on the outer periphery of the suction pipe (3) with the check valve, the vacuum cleaner hose or the cleaning hose and the suction pipe (3) with the check valve are connected to the adjusting member (31 ) Are in close contact with each other. After that, when the vacuum cleaner is turned on and operated, the air inside the box body (1) is sucked and discharged to the outside. If this state is continued, the inside of the box body (1) is depressurized and the outside of the box body (1) or the inner lid (2) is slightly recessed, so the vacuum cleaner should be turned on when it begins to dent or when a squeak noise is generated. Stop. This completes the work of reducing the pressure. In this case, a reduced pressure state can be obtained in about 2 to 3 minutes. What is necessary is just to carry to a house or a predetermined place in this pressure reduction state. In addition, when using the thing of the structure shown in FIG. 1 and FIG. 3 and reducing pressure with a vacuum cleaner, the non-return valve which protrudes from the bottom face of the inner lid (2) is attached to the vacuum cleaner hose or the cleaning hose as described above. Insert into suction pipe (3). When the cleaner is turned on and operated, the air inside the box body (1) is sucked, and after the inside of the box body (1) is depressurized, the cleaner is stopped as described above. Then, if the lid (52) is attached to the upper portion of the cylindrical body (51) and the outer lid (6) is further attached to the upper portion of the inner lid (2), the decompression operation is completed.
次に本発明品による生鮮食品の鮮度保持が長時間可能となる確認実験について説明する。実験条件としては、一般のクーラーボックスで収納容量４０リットルのものを使用し、且つ、内部の空気吸引可能に改造したものを本発明品として用いた。このボックス本体（１）の中に約半分氷を入れ、且つ、鶏肉を約２００グラム用意し、それを５つに切って入れると共に炭酸飲料水を２本入れて実験した。又、この時、ボックス本体（１）の収納部の空気を吸引手段（４）によって外部に排出させた際の空気の排出具合としては、ボックス本体（１）と蓋体で密閉した後、ボックス本体（１）或いは蓋体が凹み、異音が発生した時点で空気の排出を終了して実験を開始した。 Next, a description will be given of a confirmation experiment in which the freshness of the fresh food product according to the present invention can be maintained for a long time. As an experimental condition, a general cooler box with a storage capacity of 40 liters was used and a product modified so as to be able to suck air inside was used as a product of the present invention. About half of the ice was put into the box body (1), and about 200 grams of chicken were prepared and cut into five pieces, and two carbonated drinks were put in the experiment. At this time, the air in the storage portion of the box body (1) is discharged to the outside by the suction means (4). After the air is sealed by the box body (1) and the lid, the box When the main body (1) or the lid body was depressed and abnormal noise was generated, the discharge of air was terminated and the experiment was started.
この実験内容としては、先ず、ボックス本体（１）を１日目は室内（約２０℃）に置き、２日目と３日目は屋外（最高温度約３０℃）に置き、４日目は室内に置き、５日目に開いて中身を確認すると、氷が約１割前後残っており、鶏肉には、色の変化が殆どなく且つ腐敗臭もないものであり、これを食してみたが味の低下はなかった。また炭酸飲料水を飲んでみたが冷えた状態で美味しいものであった。
尚、ボックス本体（１）に温度センサー（７）や減圧計が配置されていない状態で実験したため、詳細なデーターは採取できなかったが、生鮮食品の鮮度保持が長時間可能なことが確認できた。一方、従来のクーラーボックスを使用した際の生鮮食品の鮮度保持は、一般的に半日が限度であり、クーラーボックス内の氷は２〜３時間で溶けてしまうのが現状である。
As for the contents of this experiment, the box body (1) is first placed indoors (about 20 ° C) on the first day, and outdoors on the second and third days (maximum temperature about 30 ° C). When it was placed indoors and opened on the 5th day, about 10% of the ice remained, and the chicken had little color change and no rot odor. There was no loss of taste. I tried drinking carbonated water, but it was delicious in the cold state.
In addition, since the experiment was conducted without the temperature sensor (7) or pressure gauge installed in the box body (1), detailed data could not be collected, but it was confirmed that the freshness of fresh food could be maintained for a long time. It was. On the other hand, the freshness of fresh food when using a conventional cooler box is generally limited to half a day, and the ice in the cooler box melts in 2 to 3 hours.
次にボックス本体（１）の収納部の冷温保持が長時間に渡って可能となる確認実験について説明する。実験条件としては、図１に示すようなボックス本体（１）の収納部の中に約半分氷を入れ、３６時間後に開き、内部温度を測定すると共に収納部の中に残っている氷の状態を観察した。尚、従来品のボックス本体（１）の収納部の中にも約半分氷を入れ、氷の溶け具合と内部温度も並行して測定した。 Next, a description will be given of a confirmation experiment that enables the storage of the box body (1) to be kept cold for a long time. As experimental conditions, about half of ice is put into the storage part of the box body (1) as shown in FIG. 1, and it opens after 36 hours, the internal temperature is measured, and the state of ice remaining in the storage part Was observed. In addition, about half ice was also put in the storage part of the box body (1) of the conventional product, and the degree of ice melting and the internal temperature were measured in parallel.
結果としては、温度と時間の関係が図６のようなグラフとなった。つまり、本発明品は、従来品と同様に始めは、５℃に内部温度が下がるまでに略５分を要し、その後、５℃を保持しながら氷が溶け始める。この時、５℃を保持している正確な時間は確認できなかったが、１２時間を経過した後から氷が少しずつ溶けると共に、温度も少しずつ上昇し、３６時間後で７℃になった。収納部の中に残っている氷の量としては、約７〜８割の氷がまだ残っていた。このため、従来品よりも１０倍以上の保冷保持時間が確認出来たので、３６時間で実験の継続を中止した。
一方、従来品の場合は、５℃を約３時間保持した後、氷が溶けてなくなると、徐々に温度が上昇し、約６時間で１７℃（略室温）になった。この結果、従来品に於いては生鮮食品の保冷保持時間としては４時間前後であった。
As a result, the relationship between temperature and time became a graph as shown in FIG. That is, the product of the present invention takes about 5 minutes for the internal temperature to drop to 5 ° C. at the beginning as in the conventional product, and then the ice begins to melt while maintaining 5 ° C. At this time, the exact time of holding at 5 ° C. could not be confirmed, but after 12 hours passed, the ice melted little by little, and the temperature rose little by little and reached 36 ° C. after 36 hours. . About 70 to 80% of ice remained in the storage unit. For this reason, since the cold holding time 10 times or more than the conventional product was confirmed, the continuation of the experiment was stopped in 36 hours.
On the other hand, in the case of the conventional product, when the ice was not melted after holding at 5 ° C. for about 3 hours, the temperature gradually increased to 17 ° C. (approximately room temperature) in about 6 hours. As a result, in the conventional product, the keeping time for keeping the fresh food was around 4 hours.
このように生鮮食品を本発明品に入れて収納しておけば、従来よりも鮮度保持や保冷保持が長時間に渡って可能なものとなる。この結果、本発明品は単にレジャー用に使用するだけでなく、例えば、災害による長時間の停電時に、冷蔵庫の代りに生鮮食品を収納すれば、保冷保存が可能となり、又、医療或いは他の方面にも利用が可能なものとなるため、汎用性が広がるものとなる。 In this way, if the fresh food is stored in the product of the present invention, it is possible to keep freshness and keep cold for a longer time than before. As a result, the product of the present invention can be used not only for leisure purposes, but also can be kept cold if a fresh food is stored instead of a refrigerator in the event of a long power outage due to a disaster. Since it can be used also in the direction, versatility is expanded.
