Description

本発明は、複合容器に関する。 The present invention relates to a composite container.

従来から、軟包装袋に板紙を固定して、自律機能を有する容器が、公知のものとして多数存在する。 Conventionally, there are many known containers having an autonomous function by fixing paperboard to a flexible packaging bag.

例えば、特許文献１の包装用袋では、密封袋の下方外周面に筒状体を重合させて、自立可能に構成されている。しかしながら、このような構成では、密封袋を開口させた状態で自立させることができないという問題点がある。 For example, the packaging bag of Patent Document 1 is configured to be self-supporting by polymerizing a cylindrical body on the lower outer peripheral surface of the sealing bag. However, in such a structure, there exists a problem that it cannot be made to stand by in the state which opened the sealing bag.

また、特許文献２の包装体では、袋体の底部側外面に接着固定された筒状紙体の折曲部に折込部を設け、該折込部で袋体の開口状態を維持したまま自立するように構成している。さらに、特許文献３の複合容器でも、軟包装袋の外面に接着固定されたスリーブ材の折曲部近傍に略くの字状又は略円弧状の押し込み外折れ線を設け、該外折れ線で軟包装袋の開口状態を維持したまま自立するように構成している。前記２つの構成では、袋体又は軟包装袋を開口させた状態で自立させることはできるが、筒状紙体又はスリーブ材に力が加わると、変形状態を維持できなくなるという問題点がある。 Moreover, in the package body of patent document 2, a folding part is provided in the bending part of the cylindrical paper body adhere | attached and fixed to the bottom part side outer surface of a bag body, and it becomes independent, maintaining the opening state of a bag body in this folding part. It is configured as follows. Furthermore, even in the composite container of Patent Document 3, a substantially U-shaped or substantially arc-shaped push-out fold line is provided in the vicinity of the bent portion of the sleeve material that is adhesively fixed to the outer surface of the soft wrapping bag. The bag is configured to be independent while maintaining the open state of the bag. In the two configurations, the bag body or the flexible packaging bag can be self-supported in an opened state, but there is a problem that when a force is applied to the cylindrical paper body or the sleeve material, the deformed state cannot be maintained.

次に、本実施形態に係る複合容器１の製造方法について、一例を挙げながら説明することとする。 Next, the manufacturing method of the composite container 1 according to this embodiment will be described with an example.

図４は、第１実施形態に係る複合容器１の軟包装袋２と外装体３との固定方法を示している。まず、未封入の軟包装袋２に内容物を充填した後、公知の方法で軟包装袋２の開口部を封止する。この封止状態の軟包装袋２の前方側の外周面と外装体３の前面部２３の内面とをホットメルト接着剤で接着するが、スリーブ領域２０の変形が困難とならないように、破断部１５の下方切取線１７から下方に所定の間隔ｄ_１をあけて横方向に接着剤を塗布する。間隔ｄ_１は、５ｍｍ〜１０ｍｍの間隔である。さらに、電子レンジ等の加熱によって接着剤が溶融しても接着剤の流れ落ちが一定の位置で止まるように、前記横接着部から５ｍｍ〜１０ｍｍの間隔をあけた位置から外装体３の下辺部９の手前まで、下辺部９に対して垂直となる縦方向に接着剤を塗布する。縦接着部の下端と外装体３の下辺部９との間隔ｄ_２は、５ｍｍ〜１０ｍｍの間隔である。図４に例示したものでは、接着剤の接着力を確保するため、縦接着部は、横接着部の下方中央とその左右両側の３箇所である。次に、外装体３の右側領域を軟包装袋２の後方側に折り曲げた後、外装体３の左側領域も軟包装袋２の後方側に折り曲げて、接着剤等で左辺部１０側の端部を糊代１１ａに貼り合わせる。さらに、折曲蓋部８ａを折り曲げて、接着剤等で折曲蓋部８ａを上辺部８側の端部に貼り合わせれば、本実施形態に係る複合容器１の製造が完了する。 FIG. 4 shows a method for fixing the flexible packaging bag 2 and the outer package 3 of the composite container 1 according to the first embodiment. First, after filling the unsealed soft packaging bag 2 with the contents, the opening of the soft packaging bag 2 is sealed by a known method. The outer peripheral surface on the front side of the soft packaging bag 2 in the sealed state and the inner surface of the front surface portion 23 of the outer package 3 are bonded with a hot melt adhesive, but the rupture portion does not become difficult to deform the sleeve region 20. The adhesive is applied in the lateral direction with a predetermined distance d ₁ downward from the 15 lower cut line 17. Distance _{d 1} is the spacing of 5 mm to 10 mm. Further, the lower side portion 9 of the outer package 3 is spaced from the lateral adhesive portion by a distance of 5 mm to 10 mm so that the flow of the adhesive stops at a fixed position even when the adhesive is melted by heating such as a microwave oven. The adhesive is applied in the longitudinal direction perpendicular to the lower side portion 9 until the front side. Distance _{d 2} between the lower edge 9 of the lower end of the longitudinal adhesive portion and the outer body 3 is the spacing 5 mm to 10 mm. In the example illustrated in FIG. 4, in order to secure the adhesive strength of the adhesive, the longitudinally bonded portions are the lower center of the laterally bonded portion and the three left and right sides. Next, after the right region of the outer package 3 is folded to the rear side of the soft packaging bag 2, the left region of the outer package 3 is also folded to the rear side of the soft packaging bag 2, and the end on the left side 10 side with an adhesive or the like The part is bonded to the glue margin 11a. Furthermore, if the folding lid portion 8a is bent and the folding lid portion 8a is bonded to the end portion on the upper side portion 8 side with an adhesive or the like, the manufacture of the composite container 1 according to the present embodiment is completed.

次に、第１実施形態に係る複合容器１の使用方法とその作用について説明することとする。 Next, the usage method and operation of the composite container 1 according to the first embodiment will be described.

図５は、第１実施形態に係る複合容器１の組立方法を示している。本実施形態に係る複合容器１を使用する場合、ます、外装体３の破断部１５を破断して分離領域１９を複合容器１から取り除く。次に、開封用の上方切欠部４より封入シール部を切り取って軟包装袋２を開封した後、スリーブ領域２０にある一対の下方折曲部２５，２６を把持し、親指と親指以外の４本の指を使って一対の下方折曲部２５，２６をそれぞれ同時に所定の位置まで内側に押し込む。一対の下方折曲部２５，２６は所定の位置まで押し込まれると、押し込み部２１，２２が下方折曲部２５，２６を中心軸として展開し、これに伴って、図５に示すように、外装体３のスリーブ領域２０が筒状に変形して軟包装袋２の開封部を開口させる。外装体３のスリーブ領域２０は、このような変形状態を維持することによって、軟包装袋２の自立状態を補助するとともに、開口状態も維持する。 FIG. 5 shows an assembling method of the composite container 1 according to the first embodiment. When the composite container 1 according to this embodiment is used, first, the fractured portion 15 of the outer package 3 is broken to remove the separation region 19 from the composite container 1. Next, after the sealed sealing portion is cut out from the upper cutout portion 4 for opening and the flexible packaging bag 2 is opened, the pair of lower bent portions 25 and 26 in the sleeve region 20 are gripped, and the portions other than the thumb and the thumb 4 are gripped. Using a finger, the pair of lower bent portions 25 and 26 are simultaneously pushed inward to a predetermined position. When the pair of lower bent portions 25 and 26 are pushed to a predetermined position, the pushed portions 21 and 22 are developed with the lower bent portions 25 and 26 as the central axis, and as shown in FIG. The sleeve region 20 of the outer package 3 is deformed into a cylindrical shape, and the opening portion of the flexible packaging bag 2 is opened. By maintaining such a deformed state, the sleeve region 20 of the exterior body 3 assists the self-standing state of the flexible packaging bag 2 and also maintains the open state.

一対の押し込み部２１，２２が変形した状態になると、スリット３５，３６，３７，３８によって規定される突出部が前後方向にそれぞれ突出し、スリット３５，３６，３７，３８による切目が開口した状態となる。このため、前面部２３及び後面部２４に対して内側方向に力を同時に加えたとしても、開口状態の切目で力の伝達が遮断され、スリーブ領域２０の変形状態が容易に解除されることはない。このように、本実施形態では、外装体３の変形状態を維持して、電子レンジでの加熱調理中の転倒を確実に防止することができ、使用中の安全性を確保することが可能である。 When the pair of pushing portions 21 and 22 are in a deformed state, the protruding portions defined by the slits 35, 36, 37, and 38 protrude in the front-rear direction, respectively, and the cuts by the slits 35, 36, 37, and 38 are opened. Become.
