次に逆止弁について第２図に基づいて詳述する。Next, the check valve will be described in detail with reference to FIG.
逆止弁はゴム又はゴム状弾性体でつくられた傘形密封部
１と硬質樹脂製のストッパー２とからなり、これらは別
々に成形されたもので、以下に述べる如く両者は無理嵌
めにより一体化されている。The check valve is composed of an umbrella-shaped sealing portion 1 made of rubber or a rubber-like elastic body and a stopper 2 made of hard resin, which are molded separately. As described below, they are integrated by force fitting. Has been converted.
傘形密封部１は傘状に形成されており、内側中央に嵌合
孔1aを有し、その入口内径は、ストッパー２の拡径頭部
2aが無理嵌めされるように該頭部2aの直径よりも若干小
さく成形されている。また密封部１は傘の周辺に当る部
分に切欠部1bを有する。３は切欠部1bに対向して蓋５に
設けられた通気孔である。傘形密封部１の周縁先端1cは
蓋５の面に気密に接触する如く構成される。The umbrella-shaped sealing portion 1 is formed in an umbrella shape, has a fitting hole 1a at the center of the inside, and the inner diameter of the inlet is the enlarged head of the stopper 2.
The head 2a is formed to have a diameter slightly smaller than that of the head 2a so that the head 2a can be forcibly fitted. In addition, the sealing portion 1 has a cutout portion 1b at a portion corresponding to the periphery of the umbrella. Reference numeral 3 denotes a ventilation hole provided in the lid 5 so as to face the cutout portion 1b. The peripheral edge tip 1c of the umbrella-shaped sealing portion 1 is configured to come into airtight contact with the surface of the lid 5.
ストッパー２の軸2bの直径は蓋５の開口４の直径より小
さくなっており、従って軸２は開口４内を遊動自在であ
る。軸2bの下方には開口４より大きな直径を有する円板
2cが形成されている。The diameter of the shaft 2b of the stopper 2 is smaller than the diameter of the opening 4 of the lid 5, so that the shaft 2 can freely move in the opening 4. A disc having a diameter larger than the opening 4 below the shaft 2b.
2c is formed.
またストッパー２の拡径頭部2aの直径は蓋５の開口４の
それよりやや大きく形成されており、頭部2aを蓋５の裏
側より開口４に無理嵌めの状態で挿入する。従って、逆
止弁の傘形密封部１を取り外して洗う際にストッパー２
が蓋５から容易には外れない。The diameter of the expanded head 2a of the stopper 2 is slightly larger than that of the opening 4 of the lid 5, and the head 2a is inserted from the back side of the lid 5 into the opening 4 by force. Therefore, when the umbrella-shaped sealing portion 1 of the check valve is removed and washed, the stopper 2
Does not come off easily from the lid 5.
さらに挿入したストッパー２の拡径頭部2aに傘形密封部
１の嵌合孔1aを無理嵌めして一体化すれば逆止弁が形成
され、傘の周縁先端1cが蓋５の面に押圧状態で気密に接
触する構成となる。Further, if the fitting hole 1a of the umbrella-shaped sealing portion 1 is forcibly fitted and integrated with the expanded head portion 2a of the inserted stopper 2, a check valve is formed, and the tip 1c of the peripheral edge of the umbrella is pressed against the surface of the lid 5. In the state, the contact is made in an airtight manner.
本考案の逆止弁は以上の如き構成を有するから、食品の
真空密閉容器にこれを装着した場合に、以下に述べるよ
うに、食品の真空密閉容器としての機能を遺憾無く発揮
することができる。Since the check valve of the present invention has the above-mentioned structure, when it is attached to the vacuum sealed container for food, the function as a vacuum sealed container for food can be fully exerted as described below. .
加熱調理（殺菌）直後の食品を、この容器に充填して掛
けがねを係合させて密閉し、内容食品が冷却されると容
器内は真空となり、さらにこれを冷蔵すればさらに真空
度は強くなり密閉されて食品は安定して保存される。Food that has just been cooked (sterilized) is filled in this container and the eyeglasses are engaged to seal the contents. When the contents are cooled, the inside of the container becomes a vacuum, and if this is refrigerated, the degree of vacuum is further increased. It becomes strong and sealed, and the food is stably stored.
また冷えた食品でも充填したのち、掛けがねを係合させ
て密閉し、これを冷蔵すればある程度の真空となり密閉
されて短期間の保存には充分である。Also, after filling with cold food, it can be sealed for a short period of time if it is sealed by engaging a lanyard and refrigerating it.
内容食品を取り出すときは逆止弁のつまみ1eを持ち上げ
て外気を流入すればよい。When taking out the content food, the check valve knob 1e should be lifted to let in the outside air.
また電子レンジで再加熱するときは逆止弁は安全弁とし
て働き、蓋をしたままの状態で加熱することができるか
ら均一にしかも速かに内容食品を加熱することができ
る。Further, when reheating in a microwave oven, the check valve functions as a safety valve, and since the lid can be heated with the lid on, the food contents can be uniformly and quickly heated.
（考案の効果） 前記のように本考案の逆止弁は傘形密封部とストッパー
に分けて構成し無理嵌めして一体化されているので、下
記の如き実用的効果を奏する。(Effect of the Invention) As described above, the check valve of the present invention has the umbrella-shaped sealing portion and the stopper, which are separately formed and integrated by force fitting, so that the following practical effects are achieved.
傘形密封部を軸部より取り外すことができるので傘形密
封部内面およびそれに対応する蓋の面を清潔に洗うこと
ができ、その際軸部は蓋から外れない構成になっている
から、軸部の紛失のおそれがなく、家庭生活上極めて有
用である。Since the umbrella-shaped sealing portion can be removed from the shaft portion, the inner surface of the umbrella-shaped sealing portion and the surface of the lid corresponding thereto can be washed cleanly, and at that time, the shaft portion is structured so as not to come off from the lid. There is no risk of losing parts, and it is extremely useful in home life.
また軸部が軟質材で一体成形されていると蓋の開口に軸
がひっかかって自在に遊動せず逆止弁の機能を果さない
場合があるが、本考案では軸部が硬質材であるので、前
記の如き難点がなくなり、逆止弁としての機能を十分発
揮することができる。Also, if the shaft part is integrally molded with a soft material, the shaft may be caught in the opening of the lid and may not move freely and may not function as a check valve. However, in the present invention, the shaft part is a hard material. Therefore, the above-mentioned difficulties are eliminated, and the function as a check valve can be sufficiently exerted.
