Description

本発明は、開封履歴を認識することができる容器において、開封をしやすくした包装用容器に関する。 The present invention relates to a packaging container that facilitates opening in a container that can recognize the opening history.

お弁当、お惣菜、お寿司、カットフルーツなどが薄肉の合成樹脂（プラスチック）シートからなる容器に収容されて販売されていることがよく見かけられる。
この容器は、内部にほこりが侵入することを防止したり、食料品など収容物の水分の蒸発を防止したりするために容器本体に嵌合する蓋体が設けられているものが多い。
このような容器は、容器を持ち上げた際に蓋体が不意に外れてしまい、収容物が散逸したり、ほこりが侵入したりしてしまうことがある。また、中には、悪意により不正に蓋体を開封し、異物を混入させる者も存在する。 It is often seen that lunch boxes, side dishes, sushi, cut fruits, etc. are sold in containers made of thin synthetic resin (plastic) sheets.
Many of these containers are provided with a lid that fits into the container body in order to prevent dust from entering the inside and to prevent evaporation of water in the contents such as food.
In such a container, the lid may be unexpectedly removed when the container is lifted, and the contained matter may be dissipated or dust may enter. In addition, there are some who maliciously open the lid and mix in foreign substances.

しかし、蓋体を容器本体に嵌合し直してしまえば元通りに復元できるため、以前に開封されたことがあるのかを認識しづらいことがあった。蓋体が開封されたことがあるものを、商品として販売をし続けるには問題があり、回収しなければならない。特に、悪意により開封された場合は、すぐに回収しなければ、購入者に害悪を及ぼすおそれがある。 However, once the lid is refitted to the container body, it can be restored to its original state, so it was sometimes difficult to recognize whether it had been opened before. If the lid has been opened, there is a problem in continuing to sell it as a product, and it must be collected. In particular, if the package is opened maliciously, it may cause harm to the purchaser if it is not collected immediately.

そこで、例えば、下記特許文献１～３には、開蓋されたことを容易に判別することができる容器が開示されている。

上記特許文献１及び２に開示された容器は、摘み部を摘んで開封した際に蓋体の蓋外側フランジ部に切れ込みが入ることにより開封したことを確認でき、さらには、再度蓋体を用いて容器を密封することができるようにしたものである。
しかし、この容器を再度密封して開封するときには、摘み部は蓋外側フランジ部を切り裂いた片状になっているため、引き上げて蓋体を外そうとしても力が抜けてしまい開封しにくく、また、摘み部が蓋外側フランジ部から千切れてしまうおそれもあった。 It can be confirmed that the container disclosed in Patent Documents 1 and 2 has been opened by making a notch in the outer flange portion of the lid of the lid when the knob is picked and opened, and further, the lid is used again. The container can be sealed.
However, when this container is resealed and opened, the knob is in the shape of a piece with the outer flange of the lid cut apart, so even if you try to pull it up to remove the lid, the force will be lost and it will be difficult to open. There was also a risk that the knob would be torn off from the outer flange of the lid.

そこで、本発明の目的は、開封されたことを認識できるとともに蓋体を再度閉じることができる包装用容器において、蓋体を開けやすく、特に、蓋体を再度閉じた際に開けやすくした包装用容器を提供することにある。 Therefore, an object of the present invention is to make it easy to open the lid in a packaging container that can recognize that the package has been opened and can close the lid again, and in particular, for packaging that makes it easy to open when the lid is closed again. To provide a container.

本発明の一形態の包装用容器は、開口部周縁に嵌合部を備えた容器本体と、嵌合部に嵌合する被嵌合部を備えた蓋体とを有する包装用容器であって、容器本体に、開口部周縁から容器外側に張り出す本体フランジ部と、本体フランジ部に、開放部となる部分を除き、外縁沿いに立ち上がる立壁部と、蓋体に、被嵌合部付近から外側に張り出し、蓋体を容器本体に嵌合した状態で、外縁が立壁部よりも下方に位置して本体フランジ部上に載せ置かれる蓋体フランジ部と、蓋体フランジ部に、蓋体を容器本体に嵌合した状態で、開放部に位置する部分を、本体フランジ部よりも容器外側に延長して形成された摘み部と、蓋体フランジ部を切り裂き容易とし、切り裂くことにより摘み部を蓋体フランジ部から分離しない切片状にすることができる切り裂き線と、開放部付近に、本体フランジ部を外側に延長して形成した受片部と、を備えたことを特徴とする。 The packaging container of one embodiment of the present invention is a packaging container having a container body having a fitting portion on the peripheral edge of the opening and a lid having a fitting portion to be fitted to the fitting portion. , The main body flange part that projects from the peripheral edge of the opening to the outside of the container on the container main body, the standing wall part that rises along the outer edge except for the open part on the main body flange part, and the lid from the vicinity of the fitted part With the lid protruding outward and the lid fitted to the container body, the lid is placed on the lid flange and the lid flange where the outer edge is located below the vertical wall and is placed on the flange of the main body. In the state of being fitted to the container body, the part located in the open portion is extended to the outside of the container from the main body flange portion to make it easy to tear the grip portion and the lid flange portion, and the grip portion is cut by tearing. It is characterized by having a tear line that can be formed into a section shape that does not separate from the lid flange portion, and a receiving portion formed by extending the main body flange portion outward in the vicinity of the open portion.

上記形態の包装用容器は、蓋体フランジ部が立壁部で囲われているため、開放部にある摘み部のみからしか開封することができない。摘み部を摘み、開封すると切り裂き線により蓋体フランジ部が切り裂かれ、摘み部が切片状になって残るため開封したことを認識することができる。
また、受片部を設けてあることにより、蓋体を開ける際に、例えば、左手の親指と人差し指で摘み部を摘み、右手の親指と人差し指で受片部を摘み、相反する方向に力を加えて開けことができるため、開封作業がしやすくなる。 Since the lid flange portion of the packaging container of the above form is surrounded by the vertical wall portion, the packaging container can be opened only from the knob portion in the open portion. When the pinched portion is picked and opened, the lid flange portion is torn by the tear line, and the pinched portion remains in the form of a section, so that it can be recognized that the package has been opened.
In addition, because the receiving piece is provided, when opening the lid, for example, the thumb and index finger of the left hand pick the picking part, and the thumb and index finger of the right hand pick the receiving part, and force is applied in opposite directions. In addition, since it can be opened, the opening work becomes easier.

上記形態の包装用容器において、受片部を、開放部の範囲内から本体フランジ部を容器外側に延長して形成したり、立壁部の範囲内から本体フランジ部を容器外側に延長して形成したり、開放部及び立壁部の両範囲内から本体フランジ部を容器外側に延長して形成したりすることができる。
このように、受片部を、様々な位置に設けることができ、開放部の範囲内から延長することにより切り裂き線を切り裂きやすくなり、立壁部の範囲内から延長することにより再度蓋体を開封する際に開封しやすくなり、開放部及び立壁部の両範囲内から延長することにより切り裂き線の切り裂きと蓋体の再開封の両方をしやすくなる。 In the packaging container of the above form, the receiving piece portion is formed by extending the main body flange portion from the range of the open portion to the outside of the container, or extending the main body flange portion from the range of the vertical wall portion to the outside of the container. Or, the main body flange portion can be extended to the outside of the container from within both the open portion and the vertical wall portion.
In this way, the receiving portion can be provided at various positions, and by extending from the range of the open portion, it becomes easier to tear the tear line, and by extending from the range of the standing wall portion, the lid body is opened again. When this is done, it becomes easier to open the seal, and by extending from both the open portion and the standing wall portion, it becomes easier to tear the tear line and reopen the lid.

上記形態の包装用容器において、切り裂き線を直線状に形成し、受片部を、切り裂き線の終端点を通り切り裂き線と直交する仮想線を引いた場合に、切り裂き線を形成した側とは反対の仮想線を越えた側に備えることが好ましい。
このようにすることにより、蓋体を再度開封する際に、切り裂き線の終端点と受片部が近接した位置になるため、摘み部を引き上げるときに力が入りやすく、再開封がしやすくなる。 In the packaging container of the above-mentioned form, when the ripping line is formed in a straight line and the receiving portion is drawn with an imaginary line passing through the end point of the ripping line and orthogonal to the ripping line, what is the side on which the ripping line is formed? It is preferable to prepare on the side beyond the opposite virtual line.
By doing so, when the lid is reopened, the end point of the tear line and the receiving piece are close to each other, so that force is easily applied when pulling up the knob, and resealing is easy. ..

上記形態の包装用容器において、摘み部の全面が、蓋体を容器本体に嵌合した状態で、受片部面上に重なるようにすることが好ましい。
このようにすることにより、受片部の外縁が摘み部の外縁よりも外側に位置するので、摘み部が捲れ上がれにくくなり、切り裂き線が不用意に切り裂かれることを防ぐことができる。 In the packaging container of the above-mentioned form, it is preferable that the entire surface of the knob portion overlaps the surface of the receiving portion portion with the lid fitted to the container body.
By doing so, since the outer edge of the receiving portion is located outside the outer edge of the picked portion, the picked portion is less likely to roll up and the tear line can be prevented from being inadvertently torn.

包装用容器１を開封するには、摘み部４を引き上げて開封することになる。この際、図４に示すように、蓋体フランジ部３４の外縁部が立壁部３４ａに囲われているので、蓋体２を開封するために摘まむ箇所は開放部３４ｂからはみ出した摘み部４のみであり、摘み部４を摘まみ開封するしかない構造になっており、他の箇所からは開封できない。
開封する際に、例えば、左手で摘み部４を摘み、右手で受片部７を摘まんで相反する方向に引くことにより、切り裂き線５が切り裂かれ始める。切り裂き線５が終端点まで切り裂かれると力が蓋体２にかかり持ち上げられ、嵌合部３３及び被嵌合部２３の嵌合状態が解かれることにより、蓋体２が外れ、開封することができる。そして、摘み部４は、蓋体２から完全に切断されることなく切片状に残るため、この蓋体２は一度開封されたことがあることを認識することができる。 In order to open the packaging container 1, the knob 4 is pulled up to open the package. At this time, as shown in FIG. 4, since the outer edge portion of the lid flange portion 34 is surrounded by the vertical wall portion 34a, the portion to be picked to open the lid 2 is the grip portion 4 protruding from the open portion 34b. It has a structure in which the picking portion 4 can only be picked and opened, and cannot be opened from other parts.
At the time of opening, for example, by picking the picking portion 4 with the left hand and picking the receiving portion 7 with the right hand and pulling them in opposite directions, the tear line 5 begins to be torn. When the tear line 5 is torn to the end point, a force is applied to the lid 2 and lifted, and the fitted state of the fitting portion 33 and the fitted portion 23 is released, so that the lid 2 can be disengaged and opened. can. Then, since the picking portion 4 remains in a section shape without being completely cut from the lid body 2, it can be recognized that the lid body 2 has been opened once.

この蓋体２を用いて容器本体３に再閉蓋することができる。
再閉蓋は、上記と同様に、蓋体２を容器本体３に載せて上側から押圧し、嵌合部３３及び被嵌合部２３を嵌合させればよい。
この蓋体２には、切り裂き線５が切り裂かれて摘み部４が切片状に蓋体２に残っているため、以前に開封した履歴があることを認識することができる。 The lid 2 can be used to reclose the container body 3.
For the reclosing, the lid 2 may be placed on the container body 3 and pressed from above to fit the fitting portion 33 and the fitted portion 23 in the same manner as described above.
Since the tear line 5 is torn in the lid 2 and the pinched portion 4 remains in the lid 2 in the form of a section, it can be recognized that the lid 2 has a history of being opened before.

再閉蓋した包装用容器１を開封するには、例えば、左手で切片状になった摘み部４を摘み、右手で受片部７を摘まんで相反する方向に引くことにより行うことができる。この際、受片部７を設けたことにより切り裂き線５の終端点付近に力をうまく加えることができるため、嵌合部３３及び被嵌合部２３の嵌合を解除しやすくなり、蓋体２を外して開封することができる。 The reclosed packaging container 1 can be opened, for example, by picking the section-shaped picking portion 4 with the left hand and picking the receiving portion 7 with the right hand and pulling them in opposite directions. At this time, since the force can be applied well near the end point of the tear line 5 by providing the receiving piece portion 7, it becomes easy to release the fitting of the fitting portion 33 and the fitted portion 23, and the lid body. 2 can be removed and opened.

また、包装用容器１は、受片部７の位置を変更することにより、上記第一から第五実施形態で示したように、力の加わり方を変えることができ、受片部７を使用者や使用方法を想定して様々な位置に設けた構成にすることができる。 Further, in the packaging container 1, by changing the position of the receiving piece portion 7, the way in which the force is applied can be changed as shown in the first to fifth embodiments, and the receiving piece portion 7 is used. It can be configured in various positions assuming the person and usage.

包装用容器１は、蓋体２を容器本体３に内嵌合する構造にしてあるが、これに限定されるものではなく、外嵌合や内外嵌合する構造にしてもよい。 The packaging container 1 has a structure in which the lid 2 is internally fitted to the container body 3, but the present invention is not limited to this, and the outer fitting or the internal and external fitting may be used.

上記実施形態の構成態様は、本発明を限定するものとして挙げたものではなく、技術目的を共通にする限り変更は可能であり、本発明はそのような変更を含むものである。 The configuration of the above embodiment is not mentioned as limiting the present invention, and can be changed as long as the technical object is common, and the present invention includes such a change.
