【発明の属する技術分野】
本発明は搾乳具で搾り取った母乳を入れて密閉保存する母乳保存袋に関する。
【０００２】
【従来の技術】
母乳保存袋の一形式として、２枚のフィルムを重ね、上下両端と左右両側をヒートシールにより溶着して密封した柔軟扁平な袋体に形成し、袋体の上端の左右両側に切り破りにより袋口を形成するための切込を設け、左右の切込を結ぶ直線の下方に硬質プラスチック製の帯片を表裏両側に固着し、表側の帯片の下方に帯片と平行に両面粘着テープを貼着し、テープに保護紙を被着したものが知られている。
この母乳保存袋を使うときは、切込から切り破って袋口を形成し、帯片の左右両端部を指で押さえる。すると帯片が湾曲して袋口が開くので、袋口から母乳を充填する。その後、帯片を巻き込むようにして袋口を折り重ね、巻き込み部が解けないように、保護紙を剥がして粘着テープに巻き込み部を粘着して袋口を閉じる。
【０００３】
【発明が解決しようとする課題】
ところで、従来の母乳保存袋は、帯片の左右両端を押さえたときに表裏の帯片が互いに離れて袋口の外側へ湾曲すれば、うまく袋口が開くが、２枚のフィルムの密着度が高いと、一方の帯片が他方の帯片に密着したまま湾曲するので、うまく袋口が開かず、使い勝手がはなはだ悪い。
本発明はかかる問題点に鑑み、簡単な操作で確実に袋口を開くことのできる母乳保存袋を提供することを目的とする。
【０００４】
【課題を解決するための手段】
請求項１に記載の発明は、２枚のフィルムを重ね、上下両端と左右両側をヒートシールにより溶着して密封した柔軟扁平な袋体に形成し、該袋体の上端の左右両側に切り破りにより袋口を形成するための切込を設けると共に、左右の切込を結ぶ直線の下方に硬質プラスチック製の帯片を表裏両側に前記直線とほぼ平行に固着し、表側の帯片の下方に帯片とほぼ平行に両面粘着テープを貼着し、テープに保護紙を被着した母乳保存袋において、表裏両帯片のうち裏側の帯片の中心部に摘み片を連結したことを特徴とする。
請求項２に記載の発明は請求項１に記載の母乳保存袋において、前記表側の帯片の中心部に縦の折曲線を形成したことを特徴とする。
請求項３に記載の発明に係る母乳保存袋は請求項１又は請求項２に記載の母乳保存袋において、前記袋体の表面に母乳保存量を示す目盛りを印刷したことを特徴とする。
【０００５】
【発明の作用・効果】
本発明に係る母乳保存袋の袋口を開くには、切込から切り破って袋口を形成し、次に一方の手の指で帯片の左右両端を押さえながら、他方の手の指で摘み片を引っ張る。摘み片を引っ張ると、２枚のフィルムが強く密着していても、一方の帯片が外側へくの字に湾曲して他方の帯片から離れる。
とくに本発明では、表側の帯片ではなくて裏側の帯片に摘み片を連結している。表側の帯片に摘み片を連結した場合、袋体の表側には両面粘着テープが貼着されているため、摘み片を引っ張っても両面粘着テープの上端から袋体が折れ曲がってしまい、袋口が開き難い。これに対し本発明では両面粘着テープが貼着されていない袋体裏側の帯片に摘み片を連結したので、摘み片を引っ張ったとき袋体が両面粘着テープの上端から折れ曲がり難く、確実に袋口を開くことができる。そのため、母乳バックの使い勝手が良くなる。
また、表側の帯片の中心部に縦の折曲線を形成することにより、帯片の両端部を押さえたとき帯片が折曲線から折れ曲がるので、より確実に帯片が湾曲して袋口を開くことができる。
さらに、袋体に目盛りを印刷したので、母乳の保存量がわかり使い勝手が一層よくなる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a breast milk storage bag in which breast milk squeezed by a milking implement is stored in a sealed state.
[0002]
[Prior art]
As one type of breast milk storage bag, two films are stacked, and the upper and lower ends and the left and right sides are welded by heat sealing to form a sealed, flexible flat bag, and the bag is cut to the left and right sides at the upper end of the bag. A notch for forming the mouth is provided, and a hard plastic strip is fixed to the front and back sides below a straight line connecting the left and right cuts, and a double-sided adhesive tape is provided below the front strip in parallel with the strip. It is known that a tape is covered with a protective paper.
When using this breast milk storage bag, the bag opening is formed by cutting from the cut, and the left and right ends of the strip are pressed with fingers. Then, the strip is bent and the bag mouth is opened, so that breast milk is filled from the bag mouth. Thereafter, the bag mouth is folded up so that the strip is involved, and the protective paper is peeled off and the bag is closed with an adhesive tape so that the wound portion is not unraveled.
[0003]
[Problems to be solved by the invention]
By the way, in the conventional breast milk storage bag, if the front and back strips separate from each other and bend to the outside of the bag mouth when the left and right ends of the strip are pressed, the bag mouth is opened well, but the adhesion of the two films is If it is high, one of the strips will bend while keeping close contact with the other strip, so that the bag mouth will not open well and the usability will be extremely poor.
The present invention has been made in view of the above problems, and has as its object to provide a breast milk storage bag that can reliably open the bag mouth with a simple operation.
[0004]
[Means for Solving the Problems]
According to the first aspect of the present invention, two films are stacked, and the upper and lower ends and the left and right sides are welded by heat sealing to form a flexible flat bag which is sealed, and the upper end of the bag is cut off at the left and right sides. In addition to providing a cut for forming a bag mouth, a hard plastic strip is fixed on the front and back sides substantially parallel to the straight line below the straight line connecting the left and right cuts, and below the front side strip. In a breast milk storage bag in which a double-sided adhesive tape is stuck substantially parallel to the strip and a protective paper is applied to the tape, a pick is connected to the center of the back strip of the front and back strips. I do.
According to a second aspect of the present invention, in the breast milk storage bag according to the first aspect, a vertical fold curve is formed in a central portion of the front side strip.
A breast milk storage bag according to a third aspect of the present invention is characterized in that, in the breast milk storage bag according to the first or second aspect, a scale indicating a breast milk storage amount is printed on a surface of the bag body.
[0005]
[Action and Effect of the Invention]
In order to open the bag mouth of the breast milk storage bag according to the present invention, the bag mouth is formed by cutting from the cut and then holding the left and right ends of the strip with the fingers of one hand while using the fingers of the other hand. Pull the knob. When the tab is pulled, one strip bends outwards and separates from the other strip, even though the two films are in close contact.
In particular, in the present invention, the tab is connected not to the front band but to the back band. When the tab is connected to the strip on the front side, since the double-sided adhesive tape is stuck to the front side of the bag, even if the tab is pulled, the bag is bent from the upper end of the double-sided adhesive tape, and the bag opening is closed. Is difficult to open. On the other hand, in the present invention, since the tab is connected to the strip on the back side of the bag body on which the double-sided adhesive tape is not attached, the bag body is hardly bent from the upper end of the double-sided pressure-sensitive adhesive tape when the tab is pulled, and the bag is securely inserted. You can open your mouth. Therefore, the usability of the breast milk bag is improved.
Also, by forming a vertical fold curve at the center of the front side band, the band is bent from the fold curve when pressing both ends of the band, so that the band is more reliably bent and the bag mouth is closed. Can be opened.
Further, since the scale is printed on the bag, the storage amount of the breast milk can be known, and the usability is further improved.
