Description
パルプ又はパルプを主成分とする材料から食品収納容器を形成するには、パルプ又はパルプを主成分とする材料から所定の大きさの厚紙状物に形成し、裏面にヒートシール能を有する熱可塑性樹脂を塗布し、前記厚紙状物の四隅に側面片を形成する切断部を形成した厚紙状物を、凹凸一対のプレス金型で加熱プレスすれば良い。プレス金型でプレスするには、対向する一方の側面片は、先に起立させなければならない。
(1)図3及び図4に示すように、食品収納容器に空気吸引孔6(又は空気吸引用ミシン目6´)を形成する。
(2)このようにして空気吸引孔6(又は空気吸引用ミシン目6´)を形成した容器2を、容器の個数の嵌合孔(例えば5〜10個)が形成された金型に容器の個数嵌合する。金型の真上には間隔付けて熱板が配設されている。
(3)ついで、食品収納容器と熱板の間まで、熱可塑性樹脂フィルムを引き出す。
(4)それから、熱可塑性樹脂フィルムを下降させて、食品収納容器上に載置する。この状態で熱可塑性樹脂フィルムは、若干下方にたるんでいる。金型内を減圧にして、食品収容容器の空気吸引孔6(又は空気吸引用ミシン目6´)から空気を吸引除去すると、熱可塑性樹脂フィルムは食品収納容器に密着し、下降した熱板で加熱されてラミネートする。熱板は元の位置まで上昇する。
(5)金型をスライドさせ、フイルム後端を切断する。ラミネートした食品収容容器が例えば5〜10個連結された状態で金型から取り出す。金型は、元の位置に戻す。連結された容器は、フィルム切断機で1個1個の製品に切断する。
2,2´・・・・・・食品収用容器
3,3´・・・・・・側面片重合部の端部(切断面)
4・・・・・・折込片
5,5a,5b,5c,5d・・・・・・側面片(側壁)
6・・・・・・空気吸引孔
6´・・・・・・空気吸引用ミシン目
7・・・・・・皺(空気流出路を形成する凹凸部
8・・・・・・凹部
9・・・・・・凹部上端(凹部空間の底面)

13・・・・・・リング状凸条
14・・・・・・鍔状部に連設した折曲部
16・・・・・・短いV字形の折込片
Claims (7)
- パルプ材料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を形成する切断部を形成し、四隅に隣接する側面片を連結する折込片を有し、該折込片は隣接する両側部よりも短く形成され、厚紙状物の一方の対向する側面片は、他方の対向する側面片よりも先に起立させ、凹凸金型で加熱プレスして、該折込片は前記側面片に重なり、四隅に側面片の重合部を形成し、該重合部の折込片よりも上の部分を折り返えして鍔状部を形成することによって形成された、容器内面の前記重合部の端部にパルプ材料の切断面を有することを特徴とする食品収容容器の製造方法。
- 前記折込片は、前記切断部下端に接し、前記重合部の折込片よりも上の二重の部分を下方に折り返えす請求項1に記載の製造方法。
- 前記折込片は、両側部がV字形の折込片である請求項1又は2に記載の製造方法。
- 前記ヒートシール能を有する熱可塑性樹脂が、ポリエチレン又はポリプロピレンである請求項1〜3のいずれかに記載の製造方法。
- 前記鍔状部は、断面コ字形に形成されている請求項1〜4のいずれかに記載の製造方法。
- 前記容器は、該容器に内容物を収容した後、フィルムをラッピングして開口部と前記鍔状部分上面を覆うように構成してなるトレーである請求項1〜5のいずれかに記載の製造方法。
- 前記パルプ材料が、パルプ単独又はパルプと他の植物性繊維材料との混合物である請求項1〜6のいずれかに記載の製造方法。
