Description

尚、本実施形態においては、天板２１の前端辺２１ａの両端部において、天板２１と前フラップ２２とを部分的に切り欠いた切り欠き部２１ｍが形成されているが、前端辺２１ａの両端部の高さＨ３は、該切り欠き部２１ｍが形成されていない場合の前端辺２１ａの両端部の高さである。図７において、切り欠き部２１ｍが形成されなかった場合の前端辺２１ａの両端部近傍は、破線２１ｋで示され、該破線２１ｋと、破線２１ｇ’で示される天板２１の側端辺２１ｇの延長線との接点Ｄが、前端辺２１ａの両端部である。よって、前端辺２１ａの高さＨ３は、接点Ｄから、先端辺２２ａの延長線２２ａ’と天板２１の側端辺２１ｇの延長線２１ｇ’との交点Ｅまでの距離である。 In addition, in the present embodiment, notches 21m formed by partially cutting out the top plate 21 and the front flap 22 are formed at both ends of the front end side 21a of the top plate 21. The height H3 of both end portions is the height of both end portions of the front end side 21a when the cutout portion 21m is not formed. 7, cut near both ends of the front edge 21a when out portion 21 m is not formed is indicated by the dashed line 21k, the該破line 21k, the side end edge 21g of the top plate 21 shown by a broken line 21g ' The contact point D with the extension line is the both ends of the front end side 21a. Therefore, the height H3 of the front end edge 2 1 a from the contact D, a distance to the intersection E between 'extension 21g of the side end edge 21g of the top plate 21' leading edge 22 a of the extension line 22a.

また、本発明において、前端辺２１ａの両端部から天板２１の後端辺２１ｄまでの距離Ｌ３が、天板２１の側端辺２１ｇの長さであり、該距離Ｌ３は、側板１３，１４の開口側の端辺の長さＬ２と等しく形成される。 Further, in the present invention, the distance L3 from the two ends of the front side 21a to the rear end side 21 d of the top plate 21, the length of the side end edge 21g of the top plate 21, the distance L3 is the side plate 13, It is formed to be equal to the length L2 of the end side of the opening 14 on the opening side.

さらに、本発明においては、天板２１の後端辺２１ｄ側においても、前端辺２１ａと同様に、後端辺２１ｄの中央部を後板１２側に突出する切り込み部２１ｅとすることで、天板２１を後端辺２１ｄにおいて折り曲げた際に、図１，図３（ａ），図３（ｄ），図４に示すように、天板２１の一部が後方に突出する突出片２１ｆとなり、後板１２の天板２１との連接側には、図３（ｅ）、図４に示すように、該突出片２１ｆに対応する孔部２１ｉが形成され、包装容器内の蒸気抜きが形成される。 Further, in the present invention, also on the rear end side 21d side of the top plate 21, similarly to the front end side 21a, the central portion of the rear end side 21d is formed as the cut portion 21e protruding toward the rear plate 12 side. When the plate 21 is bent along the rear end side 21d, as shown in FIGS. 1, 3(a), 3(d) and 4, a part of the top plate 21 becomes a protruding piece 21f protruding rearward. As shown in FIGS. 3(e) and 4, the hole 21i corresponding to the protruding piece 21f is formed on the side of the rear plate 12 that is connected to the top plate 21 to form a steam vent in the packaging container. To be done.

容器部がテーパー形状の場合、図１０に示すように、前板１１，後板１２，両側板１３，１４の形状が、開口側の端辺よりも底板１５側端辺が短い台形である以外、前板１１，後板１２，両側板１３，１４及び天板２１，前フラップ２２の基本構成とその好ましい形態については先に示した実施形態と同じである。また、本実施形態の場合、底板１５と前板１１，後板１２，両側板１３，１４とを接続して容器部の形状を維持するために、底板１５の外周に前板１１，後板１２，両側板１３，１４の下端辺を連接し、前板１１と後板１２のそれぞれの両側辺に固定片１１ｂ，１１ｃ，１２ｃ，１２ｄを連接し、固定片１１ｂ，１２ｃを側板１３に、固定片１１ｃ、１２ｄを側板１４に接着固定する。 In the case where the container portion has a tapered shape, as shown in FIG. 10, the shapes of the front plate 11, the rear plate 12, and the both side plates 13 and 14 are trapezoidal, in which the edges on the bottom plate 15 side are shorter than the edges on the opening side. The basic configurations of the front plate 11, the rear plate 12, both side plates 13 and 14, the top plate 21, and the front flap 22 and their preferable forms are the same as those of the above-described embodiment. In addition, in the case of the present embodiment, in order to maintain the shape of the container part by connecting the bottom plate 15 to the front plate 11, the rear plate 12, and the both side plates 13 and 14, the front plate 11 and the rear plate are provided on the outer periphery of the bottom plate 15. 12, the lower end sides of the both side plates 13 and 14 are connected, the fixing pieces 11b, 11c, 12c and 12d are connected to the both side edges of the front plate 11 and the rear plate 12, respectively, and the fixing pieces 11b and 12c are connected to the side plate 13. The fixing pieces 11c and 12d are adhesively fixed to the side plate 14.
