[Solution] A pulp material, or the like, is formed into a heavy duty paper article. The heavy duty paper article is coated with a thermoplastic resin having a heat sealing ability. The heavy duty paper article has, at each corner, side surface pieces and a folding piece connecting the adjacent side surface pieces. The top end of the folding piece is formed such that one end reaches to the middle of a flange portion at the top of the side surface pieces and the other end does not reach to the flange portion, and the side surface pieces are adhered together in an overlapping manner with the folding piece therebetween. As a result, the contact portion of the flange is formed so as to be flat, and a top seal can be provided thereto.
Description
この発明は、パルプ材料等（パルプ材料、草及び植物性樹脂）製トップシール用食品収容容器に係り、詳記すればパルプ材料等からなる厚紙状物から形成した食品収容容器に、肉、魚等を収容し斜めにしても逆さにしても、血液や液汁が滲入したりしないと共に、食品容器内に外気が侵入しないように完全密封できるようにしたトップシール用食品容器に関する。
The present invention relates to a food container for top seals made of pulp material or the like (pulp material, grass and vegetable resin), and more specifically to a food container formed from a cardboard-like material made of pulp material, meat or fish. The present invention relates to a top-seal food container which can be completely sealed so that blood and juice do not infiltrate and the outside air does not enter the food container, even if it is accommodated in a slanted body or upside down.
図1は、従来の食品収容容器を示すものであり、側面壁１と２との間に折込片３が連設され、側面片1の表面に貼着させる側面片２の折込片３より上の部分に略長方形の折り返し部4が形成されている。折り返し部4を折り返して側面片1に貼着させても表面にパルプ材料等の切断面が出ないので、血液や液汁が滲むように滲入して容器の外観を汚くするという問題は生じない。
FIG. 1 shows a conventional food container, in which a folding piece 3 is continuously provided between the side walls 1 and 2 and is placed above the folding piece 3 of the side piece 2 to be attached to the surface of the side piece 1. A substantially rectangular folded portion 4 is formed at the portion. Even if the folded-back portion 4 is folded back and attached to the side piece 1, the cut surface of the pulp material or the like does not come out on the surface, so that there is no problem that blood or liquid soaks into the container and the appearance of the container becomes dirty. ‥
しかしながら、側面壁１と２と略長方形の折り返し部4とが重なる部分は、３重となり厚くなり過ぎるので、そこへトップシールすると、厚い凹凸の段差のため、空気の隙間が生じてしまい、完全密封するというトップシールの目的が達成し得ない。
However, the portion where the side walls 1 and 2 and the substantially rectangular folded-back portion 4 overlap with each other becomes triple and becomes too thick. Therefore, when top-sealing there, a gap of air is generated due to a thick uneven step, and a complete gap is formed. The purpose of the top seal of sealing cannot be achieved.
この発明は、このような点に着目してなされたものであり、血液や液汁が滲入したりしないと共に、四隅の段差がほとんどないようにしトップシールしても空気の隙間が生じないようにしたトップシー用食品収容容器を提供することを目的とする。
The present invention has been made paying attention to such a point, and blood and liquid are prevented from infiltrating, and there are almost no steps at the four corners so that air gaps do not occur even when top-sealed. It is intended to provide a food container for top sea.
上記目的を達成するため、本発明者は鋭意研究の結果、折込片上端の一端が上になる側面片のフランジ部分の中間に達し、他端はフランジ部分に達しないようにすることにより、切断面は容器内面に出ないので、血液や液汁が滲むように滲入する問題は生じないと共に、フランジ部分の折り返し部の無い部分は厚くならないことを想到し、本発明に到達した。
In order to achieve the above-mentioned object, the present inventor, as a result of diligent research, cuts by making one end of the folding piece reach the middle of the flange portion of the side piece that is on the top and the other end not to reach the flange portion. Since the surface does not appear on the inner surface of the container, the problem of blood and liquid soaking in does not occur, and it has been conceived that the portion of the flange portion without the folded-back portion does not become thick, and the present invention has been reached. ‥
即ち本発明は、パルプ材料等から厚紙状物に形成し、該厚紙状物にヒートシール能を有する熱可塑性樹脂をコーティングし、前記厚紙状物の四隅に側面片と、隣接する側面片を連結する折込片とを有し、該折込片上端の一端が上になる側面片のフランジ部分の中間に達し、他端はフランジ部分に達しないようにし、折込片を挟んで両側面片を重合貼着させることによって、容器内面の前記重合部の端部にパルプ材料等の切断面を有しないことと、実質的に三重部分を無くしたことを特徴とする。
That is, the present invention is to form a cardboard-like material from a pulp material or the like, coat the cardboard-like material with a thermoplastic resin having a heat-sealing ability, and connect the side piece and the adjacent side piece to the four corners of the cardboard-like material. The folding piece has one end, and one end of the folding piece reaches the middle of the flange portion of the side piece which is on the upper side, and the other end does not reach the flange portion. It is characterized by not having a cut surface of pulp material or the like at the end of the polymerized portion on the inner surface of the container and by substantially eliminating the triple portion. ‥
前記折込片上端の一端が上になる側面片のフランジ部分の中間が、フランジ部分の内面側より１／３～１／２とするのが好ましい（請求項２）。
It is preferable that the middle of the flange portion of the side piece with one end of the upper end of the folding piece facing upward is 1/3 to 1/2 from the inner surface side of the flange portion (claim 2).
以上述べた如く本発明によれば、折込片上端の一端が上になる側面片のフランジ部分の中間に達し、他端はフランジ部分に達しないようにし、折込片を挟んで両側面片を重合貼着させることによって、パルプ材料等の切断面は容器内面に出ないので、血液や液汁が滲むように滲入して容器の外観を汚くするという課題を解決すると共に、三重部分が実質的にないので、トップシールしても平坦にできると言う絶大な効果を奏する。
As described above, according to the present invention, one end of the folding piece has one end reaching the middle of the flange portion of the side piece, and the other end does not reach the flange portion. By sticking, the cut surface of pulp material etc. does not appear on the inner surface of the container, so it solves the problem of infiltrating the appearance of the container by infiltrating like blood and juice so that there is substantially no triple part Therefore, even if the top seal is used, the flat effect can be achieved.
