The present invention relates to a liquid filling apparatus that forms, fills, and seals a paper container to complete the assembly, and in order to assemble the paper container, the top seal portion provided at the open end of the folded top is heated and pressurized to join. In this case, the present invention relates to a paper container top heating device that heats while cooling the outside of a pair of top portions that do not have the top fold line 3 in a state where the top portion of the gobeltop type paper container is open .

従来より、ゲーベルトップ型（両面傾斜屋根型）紙容器が清酒、焼酎、牛乳、ジュース、その他清涼飲料等の液体容器包装として広く使用されている。このゲーベルトップ型紙容器の組立充填封緘装置としては、紙容器の底部組立装置、搬送装置、液体充填装置、紙容器頂部くせ折り装置、紙容器頂部加熱装置、紙容器頂部シール装置等、さらに無菌充填の場合には紙容器殺菌装置、紙容器乾燥装置等を備えてライン化され、紙容器を成形、充填、密封して組立完成させる組立充填封緘装置が知られている（例えば、特許文献１参照）。この紙容器は、内面及び外面にヒートシール性樹脂層が積層された紙を基材とする平面素材を図５に示すように底部組立装置で四角筒状に構成し、次に、その底部１ａの端部を加熱装置で加熱後直ちに底部折り曲げ線２に沿って折曲げるとともに、その加熱部を加圧接合し、底部を形成する。
2. Description of the Related Art Conventionally, a paper bell type (both sides inclined roof type) paper container has been widely used as a liquid container package for sake, shochu, milk, juice, and other soft drinks. Assembling filling and sealing device for this paperbell top type paper container, assembling and sealing device for paper container, conveying device, liquid filling device, paper container top folding device, paper container top heating device, paper container top sealing device, etc., aseptic filling In this case, there is known an assembly filling and sealing device that is lined with a paper container sterilization device, a paper container drying device, and the like to form, fill, and seal the paper container to complete the assembly (see, for example, Patent Document 1). ). In this paper container, a planar material having a base material made of paper with heat-sealable resin layers laminated on the inner surface and the outer surface is formed into a rectangular tube shape by a bottom assembly apparatus as shown in FIG. The end of the substrate is bent along the bottom fold line 2 immediately after being heated by the heating device, and the heated portion is pressure-bonded to form the bottom.

次に、底部を形成した紙容器１内に所定の液体を充填し、あらかじめ頂部折り曲げ線３に沿って図６に示す如く折りくせを付けた頂部１ｂの端部に備えたトップシール部４を紙容器頂部加熱装置で加熱し、直ちに折畳んで紙容器頂部シール装置で加圧接合し、中身を密封した図７に示す如き紙容器１を組立完成する。
Next, the top seal portion 4 provided at the end portion of the top portion 1b, which is filled with a predetermined liquid in the paper container 1 having the bottom portion and is folded in advance along the top folding line 3 as shown in FIG. It heats with a paper container top heating apparatus, folds immediately, and press-joins with a paper container top seal apparatus, and the paper container 1 as shown in FIG.

また、上述のように紙容器１のトップシール部４を加熱する紙容器頂部加熱方法としては、例えば、紙容器の組立完成前に、紙容器頂部加熱装置でトップシール部４の内側を加熱する内周加熱部とトップシール部４の外側を加熱する外側面の加熱部との間にトップシール部４を臨ませ、次に、内周加熱部に内周加熱部中心軸と直交する揺動を与えることにより、内周加熱部に設けた多数の熱風噴射小孔より噴射する熱風を紙容器のシール部に拡散して当てて平均的に加熱し、次に紙容器頂部シール装置でこのトップシール部を加圧接合する方法が提案されている（例えば、特許文献２参照）。   Moreover, as a paper container top part heating method which heats the top seal part 4 of the paper container 1 as mentioned above, for example, before the assembly completion of the paper container, the inside of the top seal part 4 is heated by the paper container top part heating device. The top seal portion 4 is faced between the inner peripheral heating portion and the outer surface heating portion that heats the outside of the top seal portion 4, and then the inner peripheral heating portion is swung perpendicular to the central axis of the inner peripheral heating portion. The hot air sprayed from a large number of hot air spray holes provided in the inner peripheral heating portion is diffused and applied to the seal portion of the paper container and heated on average, and then this top is sealed by the paper container top seal device. A method for pressure-bonding the seal portion has been proposed (see, for example, Patent Document 2).

However, including the conventional method for heating the top of the paper container, the outside of the top seal portion where the paper container is not joined is also heated and the heat sealable resin layer on the outer surface is softened. When the seal part is pressure-bonded with the seal jaw, a part of the softened heat-sealable resin layer adheres to the seal jaw, and after pressurization, the heat-sealable resin is removed when the seal jaw leaves the top seal part. The layer may be pulled from the paper substrate and partially peeled off to cause paper peeling.

紙剥けが発生すると著しく外観を損ねて商品価値が低下するという問題がある。そのためにトップシール部のシールジョーに冷却水を流したり、紙容器頂部加熱装置にはゲーベルトップ型紙容器の頂部が開口した状態で、頂部折り曲げ線３を有しない一対の頂部の外側面のトップシール部折り曲げ線３’の近傍に冷却ガイドを設けて紙容器頂部加熱装置下での紙容器の開口端部の開口形状を保持すると共にヒートシール性樹脂層の溶融を抑制しているが、紙剥け防止が皆無に至っていないのが実情である。
特開２００２−１９７３３号公報 特開平７−２４９４０号公報 When paper peeling occurs, there is a problem that the appearance is remarkably impaired and the commercial value is lowered. For this purpose, cooling water is allowed to flow through the sealing jaws of the top seal part, or the top seals of the outer surfaces of the pair of top parts not having the top folding line 3 in the state where the top part of the paperbell top type paper container is opened in the paper container top heating device. Although a cooling guide is provided in the vicinity of the folding line 3 'to maintain the opening shape of the opening end of the paper container under the paper container top heating device and to prevent melting of the heat-sealable resin layer, The reality is that there is no prevention.
