There's a problem. Disclosure of the invention
本発明の主な目的は、 満杯に充填物を充填することができ、 連続的に成形することが でき、 さらには、 平坦な幅広のシートから包装体を形成することができる製造方法及び 製造装置を提供することである。 本発明の製造方法は、 凹部と、 この凹部周縁に形成されたフランジ部とを有する一対 の成形体の前記凹部を対向配置して前記フランジ部を溶着するとともに、 前記凹部内に 充填物が収納された包装体の製造方法であって、 表面に前記凹部に対応した窪み部が形 成された一対の回転ローラ （成形ローラ） の表面に前記一対の成形体の原反となるシ一 卜を連続的に供給するシート供給工程と、 前記シートと回転ローラとが接触する前又は 接触した後において、 回転ローラの外部に配置された加熱装置により前記シートを加熱 する加熱工程と、 前記回転ローラの窪み部に接続された真空吸引手段により生じる吸引 力で窪み部内にシートの一部を吸引し、 前記凹部を形成する凹部形成工程と、 この凹部 形成工程で形成された凹部よりもシート供給方向先端側部分を少なくとも一対の回転口 ーラ （シールローラ） により挟持して溶着し、 前記凹部同士を対向配置させた後、 凹部 よりもシート供給方向後端側部分を少なくとも一対の回転ローラ （シールローラ） によ り挟持して溶着する溶着工程と、 前記一対の回転ローラ （シールローラ） の前記シート 挟持部分近傍に配置された充填ノズルにより、 前記シ一トに形成された凹部よりもシ一 卜供給方向先端側部分が前記一対の回転ローラ （シールローラ） により溶着された後、 凹部よりもシート供給方向後端側部分が前記一対の回転ローラ （シールローラ） により 溶着されるまでの間に、 凹部に充填物を充填する充填工程と、 一対のローラ （切断ロー ラ） と、 このローラ表面から突出するとともに、 前記包装体のフランジ部の外形形状に 応じた形状の打ち抜き刃とを有する切断手段により、 前記溶着工程で溶着されたシート の溶着部分を切断する切断工程とを備えていることを特徴とする。 A main object of the present invention is to provide a manufacturing method and a manufacturing apparatus capable of being filled with a filling material fully, capable of being continuously formed, and capable of forming a package from a flat wide sheet. It is to provide. In the manufacturing method of the present invention, the recesses of a pair of molded bodies each having a recess and a flange formed on the periphery of the recess are opposed to each other, the flange is welded, and a filler is stored in the recess. A method of manufacturing a package body, comprising: forming a sheet of a pair of rotating bodies (forming rollers) having concave portions corresponding to the concave portions on the surface, the sheet being a material roll of the pair of molded bodies; A sheet supply step of continuously feeding, a heating step of heating the sheet by a heating device arranged outside the rotating roller before or after the sheet comes into contact with the rotating roller; A concave portion forming step of forming the concave portion by suctioning a part of the sheet into the concave portion by a suction force generated by vacuum suction means connected to the concave portion; The front end portion in the sheet supply direction is sandwiched and welded by at least a pair of rotating rollers (seal rollers), and the concave portions are arranged to face each other. A welding step of sandwiching and welding by a rotating roller (seal roller); and a recess formed in the sheet by a filling nozzle arranged near the sheet sandwiching portion of the pair of rotating rollers (seal roller). After the leading end portion in the sheet feeding direction is welded by the pair of rotating rollers (seal roller), the trailing end portion of the sheet feeding direction beyond the concave portion is welded by the pair of rotating rollers (seal roller). In the meantime, a filling step of filling the concave portion with the filling material, a pair of rollers (cutting rollers), projecting from the roller surface, and A cutting step of cutting a welded portion of the sheet welded in the welding step by a cutting means having a punching blade having a shape corresponding to the outer shape of the flange portion.
本発明では、 一対の回転ローラ （成形ローラ） の表面で各シートに凹部を形成すると ともに、 この回転ローラによりシートを挟持することで、 シートを互いに溶着している ため、 シートを予め筒状等に成形する必要がなく、 幅広のシートから包装体を成形する ことができる。  In the present invention, the sheet is welded to each other by forming a concave portion in each sheet on the surface of the pair of rotating rollers (forming rollers) and sandwiching the sheets by the rotating rollers. It is not necessary to mold the package, and the package can be molded from a wide sheet.
また、 本発明の製造方法では、 回転ローラ （シールローラ） の回転に伴い凹部のシ一 ト供給方向先端側部分が挟持されて溶着され、 さらに、 凹部同士が対向配置された後、 後端側部分が挟持されて溶着する。 このように、 回転ローラの回転に伴って包装体を連 続的に成形することができるので、 製造スピードを向上させることができる。  Further, in the manufacturing method of the present invention, the rotation roller (seal roller) rotates, the front end portion of the concave portion in the sheet supply direction is nipped and welded, and further, after the concave portions are arranged to face each other, the rear end side The part is pinched and welded. As described above, since the package can be continuously formed with the rotation of the rotating roller, the manufacturing speed can be improved.
さらに、 ローラ （切断ローラ） 表面に抜き打ち刃が形成された切断手段を用いている ため、 フィルムの供給速度に応じて切断手段のローラを回転させることで、 包装体の打 ち抜きも連続的に行うことができる。 これにより製造スピードをさらに向上させること ができる。 Furthermore, a cutting means having a punching blade formed on the surface of a roller (cutting roller) is used. Therefore, by rotating the roller of the cutting means in accordance with the film supply speed, punching of the package can be performed continuously. As a result, the manufacturing speed can be further improved.
また、 本発明の製造方法では、 凹部に充填物を供給した後、 凹部よりもシート供給方 向後端側部分を回転ローラ （シールローラ） により溶着する構成であるため、 充填物を 充填した後、 凹部はすぐに完全密閉される力 あるいは完全に密閉されなくても流れ方 向外周が溶着されることとなる。 従って、 凹部内の充填物が後工程においてこぼれる可 能性がなく、 これにより凹部内に満杯に充填物を供給することができる。  In addition, in the manufacturing method of the present invention, after the filling material is supplied to the concave portion, the rear end portion of the sheet feeding direction from the concave portion is welded by a rotating roller (seal roller). The concave portion is immediately completely sealed or the outer periphery in the flow direction is welded even if not completely sealed. Therefore, there is no possibility that the filling material in the concave portion will be spilled in the subsequent process, whereby the filling material can be supplied to the concave portion completely.
さらに、 本発明の製造方法では、 回転ローラ （シールローラ） 近傍に配置された充填 ノズルにより充填物を充填しており、 充填物供給時に充填物がこぼれてしまうことを防 止できる。  Further, in the manufacturing method of the present invention, the filling material is filled by the filling nozzle arranged near the rotating roller (seal roller), and it is possible to prevent the filling material from being spilled when the filling material is supplied.
本発明では、 シートと回転ローラ （シールローラ） とが接触する前又は接触した後に おいて回転ローラの外部からシートを加熱しており、 シートを凹部成形に応じた温度に 加熱することができる。 加熱装置を凹部成形に応じた高い温度に設定しても、 回転ロー ラ外部からシートを加熱する構成であるため、 回転ローラの窪み部にシートに形成され た凹部が溶着してしまうことがなく、 回転ローラの窪み部から凹部を容易に剥離させる ことができる。  In the present invention, the sheet is heated from the outside of the rotating roller before or after the sheet comes into contact with the rotating roller (seal roller), and the sheet can be heated to a temperature corresponding to the formation of the concave portion. Even if the heating device is set to a high temperature corresponding to the formation of the recess, the sheet is heated from the outside of the rotating roller, so that the recess formed in the sheet does not weld to the recess of the rotating roller. In addition, the concave portion can be easily separated from the concave portion of the rotating roller.
また、 回転ローラ （シールローラ） の外部からシートを加熱することで、 シートの溶 着部分を暖めることができ、 確実に溶着させることができる。  In addition, by heating the sheet from outside the rotating roller (seal roller), the welded portion of the sheet can be warmed, and the sheet can be reliably welded.
さらに、 本発明の製造方法により製造される包装体は、 一対の成形体の凹部と、 フラ ンジ部とを対向配置させたものであり、 フランジ部を中心として上下略対称構造となつ ている。 したがって、 本発明の製造方法では、 意匠性の高い包装体を製造することがで さる。  Furthermore, the package manufactured by the manufacturing method of the present invention has a pair of molded bodies in which the concave portion and the flange portion are arranged to face each other, and has a substantially symmetrical structure with respect to the flange portion. Therefore, according to the production method of the present invention, a package having a high design property can be produced.
なお、 包装体の凹部の形状は、 任意であり、 例えば、 凹部を対向配置させた形状を球 状、 四角形状、 ハート型等とすることが'可能である。  The shape of the concave portion of the package is arbitrary. For example, the shape in which the concave portions are opposed to each other can be spherical, square, or heart-shaped.
溶着用の回転ローラ （シールローラ） は一対でもよく、 複数対であってもよい。 すな わち、一対のローラだけでも凹部の先端側と後端側とを同時にシールすることもできる。 複数のローラで包装体本体部分と後端側の充填部分とを別個にシールしてもよい。 すな わち、 シールに際しては包装体の外周を一度にシールするのではなく、 一部を残してお き充填物の充填に用い、 その後下流の他のローラで当該充填部分を改めてシールするよ うにしてもよい。 The number of welding rotating rollers (seal rollers) may be one or more. That is, the front and rear ends of the concave portion can be simultaneously sealed with only a pair of rollers. A plurality of rollers may separately seal the package body portion and the filling portion on the rear end side. sand In other words, instead of sealing the outer periphery of the package all at once, use a part of the package for filling, and then seal the filled part again with another downstream roller. You may.
すなわち、 本発明の製造方法では、 凹部よりもシート供給方向後端部分の溶着は、 回 転ローラ （シールローラまたは成形ローラと兼用のシールローラ） により、 充填物の充 填後に完全シールすることができる。 一方、 他の方法として次のような手順を採用する ことができる。  That is, in the manufacturing method of the present invention, the welding at the rear end portion in the sheet feeding direction rather than the concave portion can be completely sealed after the filling material is filled by the rotating roller (the sealing roller or the sealing roller also serving as the forming roller). it can. On the other hand, the following procedure can be adopted as another method.
本発明の製造方法において、 前記溶着工程は、 前記充填工程の前に、 前記凹部の外周 部のうち充填物を充填するための部分を除いて溶着する一次溶着工程と、 前記充填工程 の後に、 前記充填物を充填するための部分を溶着する二次溶着工程と、 を備えることが 望ましい。  In the manufacturing method of the present invention, before the filling step, a primary welding step of welding except for a portion for filling a filler in an outer peripheral portion of the concave portion, and after the filling step, And a secondary welding step of welding a portion for filling the filler.
このような一次溶着と二次溶着とを行うために、 シート供給方向の上流側と下流側と の 2つの回転ローラを用いることができる。  In order to perform such primary welding and secondary welding, two rotating rollers on the upstream side and the downstream side in the sheet supply direction can be used.
この構成においては、 一次溶着工程で先ず包装体の外周部の溶着を行うが、 充填物を 充填するための部分は未溶着とする。 そして、 充填工程において凹部には充填物が充填 される。 この際、 例えば、 先行する一次溶着工程用の回転ローラと続く二次溶着用の回 転ローラとの間の領域に充填ノズルの先端を配置し、 一次溶着工程から送り出されたシ 一卜に形成された容器内に充填物を充填する。 これにより、 充填物は、 一次溶着工程に より一部を除き溶着されて形成された容器内に充填されるが、 この容器は未溶着の部分 があるため、 充填物は完全に密閉されず、 未溶着の部分にも充満した状態となる。 続い て、 二次溶着工程において、 包装体の未溶着の部分の溶着が行われる。 この際、 未溶着 の部分には充填物があり、 充填物を遮断するように溶着が行われる。  In this configuration, the outer peripheral portion of the package is first welded in the primary welding step, but the portion for filling the filler is not welded. Then, in the filling step, the recess is filled with the filling material. At this time, for example, the tip of the filling nozzle is arranged in a region between the rotating roller for the preceding primary welding process and the rotating roller for the subsequent secondary welding, and is formed on the sheet sent from the primary welding process. Is filled in the filled container. As a result, the filling material is filled in a container formed by welding except for a part in the primary welding step, but since the container has an unwelded portion, the filling material is not completely sealed. Unfilled portions are also filled. Subsequently, in the secondary welding step, the unwelded portion of the package is welded. At this time, there is a filler in the unwelded part, and welding is performed so as to block the filler.
これにより、 充填物以外に空洞部分等がない完全充填の包装体を得ることができる。 本発明の製造方法において、 前記包装体の一方の成形体の凹部の前記フランジ部側の 一部は、 他方の成形体のフランジ部と対向配置され、 このフランジ部と溶着されない非 溶着部となっており、 この非溶着部には、 開封用の切込みが形成され、 前記加熱工程に おいてシートを加熱する前に、 前記一対の回転ローラの前段に配置された切込み形成手 段により、 前記一方の成形体の原反となるシートに前記切込みを形成する切込み形成ェ 程を備えていることが'好ましい。 This makes it possible to obtain a completely filled package having no hollow portion other than the filler. In the manufacturing method of the present invention, a part of the concave portion of one molded body of the package body on a side of the flange portion is arranged to face a flange portion of the other molded body, and serves as a non-welded portion that is not welded to the flange portion. In the non-welded portion, a notch for opening is formed, and before the sheet is heated in the heating step, the notch forming means arranged in a preceding stage of the pair of rotating rollers makes the one-side cut. Notch forming sheet for forming the notch in a sheet serving as a raw material of the molded article It is' preferable.
切込み形成工程を設けることで、 本発明の製造方法により製造される包装体を開封し やすいものとすることができる。 例えば、 非溶着部の外側 （包装体の外側） から切込み が形成されている場合には、 ユーザが切込みから他方の成形体側に非溶着部を折り曲げ ると、 包装体が破断され、 これにより充填物を取り出すことができる。  By providing the notch forming step, the package manufactured by the manufacturing method of the present invention can be easily opened. For example, when the cut is formed from the outside of the non-welded portion (outside of the package), when the user bends the non-welded portion from the cut to the other molded body side, the package is broken, thereby filling the package. Things can be taken out.
本発明の製造装置は、 凹部と、 この凹部周縁に形成されたフランジ部とを有する一対 の成形体の前記凹部を対向配置して前記フランジ部を溶着するとともに、 前記凹部内に 充填物が収納された包装体の製造装置であって、 前記一対の成形体の原反である一対の シートを連続的に供給するシート供給手段と、 前記凹部に対応して表面に形成されると ともに、 真空吸引手段が接続された窪み部内に、 前記真空吸引手段により生じる吸引力 で前記シー卜供給手段により供給されたシー卜の一部を吸引して前記凹部を形成する一 対の回転ローラ （成形ローラ） と、 前記凹部よりもシート供給方向先端側部分を挟持し て溶着し、 前記凹部同士を対向配置させた後、 凹部よりもシート供給方向後端側部分を 挟持して溶着する少なくとも一対の回転ローラ （シールローラ） と、 前記溶着を行う回 転ローラの外部に配置され、 前記シートとこの回転ローラとが接触する前又は接触した 後において、 この回転ローラの外部から前記シートを加熱する加熱装置と、 前記溶着を 行う回転ローラ （シールローラ） の前記シート挾持部分近傍に配置され、 前記シートに 形成された凹部よりもシート供給方向先端側部分が前記この回転ローラにより溶着され た後、 凹部よりもシー卜供給方向後端側部分がこの回転ローラにより溶着されるまでの 間に、凹部に充填物を充填する充填ノズルと、前記一対の回転ローラの後段に配置され、 前記シートの溶着部分を切断する切断手段とを備え、 前記切断手段は、 一対のローラ （ 切断ローラ） と、 このローラの表面から突出しかつ前記包装体のフランジ部の外形形状 に応じた形状の打ち抜き刃とを有するものであることを特徴とする。  The manufacturing apparatus of the present invention is arranged such that the recesses of a pair of molded bodies having a recess and a flange formed on the periphery of the recess are opposed to each other, the flange is welded, and a filler is stored in the recess. A sheet supply means for continuously supplying a pair of sheets, which is a raw material of the pair of molded bodies, and a vacuum formed on the surface corresponding to the concave portion. A pair of rotating rollers (forming rollers) are formed in the recesses to which the suction means is connected, by suctioning a part of the sheet supplied by the sheet supply means with suction force generated by the vacuum suction means to form the recess. And at least one pair sandwiching and welding the front end portion of the sheet supply direction relative to the concave portion, disposing the concave portions to face each other, and then sandwiching and welding the rear end portion of the sheet supply direction relative to the concave portion. A rotating roller (seal roller), and a heating device that is disposed outside the rotating roller that performs the welding, and heats the sheet from outside the rotating roller before or after the sheet comes into contact with the rotating roller. An apparatus and a rotary roller (seal roller) for performing the welding, which is disposed near the sheet holding portion, and a portion on the leading end side in the sheet feeding direction from a concave portion formed on the sheet is welded by the rotary roller; A filling nozzle for filling the concave portion with the filling material and a pair of rotating rollers disposed after the pair of rotating rollers, before the rear end portion in the sheet supply direction is welded by the rotating roller. Cutting means for cutting the package, the cutting means comprising: a pair of rollers (cutting rollers); And wherein the one having a punching blade having a shape corresponding to the outer shape of the flange portion.
本発明では、 一対の回転ローラ （成形ローラ） の表面で各シートに凹部を形成すると ともに、 回転ローラ （シールローラ） によりシートを挟持することで、 溶着する構成と なっているので、 シートを予め筒状等に成形する必要がなく、 平坦な幅広の一対のシー 卜から包装体を成形することができる。  In the present invention, the sheet is formed in advance by forming a concave portion in each sheet on the surface of the pair of rotating rollers (forming rollers), and sandwiching the sheet by the rotating rollers (seal rollers). It is not necessary to form the package into a cylindrical shape or the like, and the package can be formed from a pair of flat wide sheets.
また、 本発明の製造装置では、 回転ローラ （シール） の回転に伴い凹部のシート供給 方向先端側部分が挟持されて溶着され、 さらに、 凹部同士が対向配置された後、 シート 供給方向後端側部分が挟持されて溶着する。 このように、 回転ローラの回転に伴って包 装体を連続的に成形することができるので、 製造スピードを向上させることができる。 切断手段は、 ローラ （切断ローラ） 表面に抜き打ち刃が形成されたものであるため、 シートの供給速度に応じて切断手段のローラを回転させることで、 包装体の打ち抜きも 連続的に行うことができる。これにより製造スピードをさらに向上させることができる。 また、 本発明の製造装置は、 凹部に充填物を供給した後、 凹部よりもシート供給方向 後端側部分を少なくとも一対の回転ローラ （シールローラ） により溶着する構成である ため、 充填物を充填した後、 凹部はすぐに完全密閉されるか、 あるいは完全に密閉され なくても流れ方向外周が溶着されることとなる。 従って、 凹部内の充填物がこぼれる可 能性がなく、 これにより凹部内に満杯に充填物を供給することができる。 Further, in the manufacturing apparatus of the present invention, the sheet is supplied to the concave portion with the rotation of the rotating roller (seal). The front end portion in the sheet feeding direction is sandwiched and welded, and further, after the concave portions are arranged to face each other, the rear end portion in the sheet feeding direction is sandwiched and welded. As described above, since the package can be continuously formed with the rotation of the rotating roller, the manufacturing speed can be improved. Since the cutting means is a roller (cutting roller) with a punching blade formed on the surface, by rotating the roller of the cutting means in accordance with the sheet supply speed, it is possible to continuously punch the package. it can. Thereby, the manufacturing speed can be further improved. In addition, since the manufacturing apparatus of the present invention has a configuration in which the filling material is supplied to the concave portion and the rear end portion of the sheet feeding direction from the concave portion is welded by at least a pair of rotating rollers (seal rollers), the filling material is filled. After that, the recess is immediately completely sealed, or the outer periphery in the flow direction is welded without completely sealing. Therefore, there is no possibility that the filling material in the concave portion is spilled, so that the filling material can be fully supplied into the concave portion.
さらに、 充填ノズルは、 回転ローラ （シールローラ） のシート挟持部分近傍に配置さ れているため、凹部に充填物を供給する際に充填物がこぼれてしまうことを防止できる。 更に、 凹部の成形時に凹部へ充填ノズルを挿入できるようにすることで、 ノズルが太く ても容器内に深く挿入することができ、 粘度の大きな充填物にも対応を容易にできる。 また、 本発明では、 シートと回転ローラ （シールローラ） とが接触する前又は接触し た後においてこの回転ローラの外部からシートを加熱しており、 シートを凹部成形に応 じた温度に加熱することができる。 このため、 成形ローラとシールローラとを一つの回 転ローラで兼用する構成において、加熱装置を凹部成形に応じた高い温度に設定しても、 回転ローラ （成形用およびシール用） の外部からシートを加熱する構成であるため、 こ の回転ローラの窪み部にシートに形成された凹部が溶着してしまうことがなく、 窪み部 から凹部を容易に剥離することができる。  Further, since the filling nozzle is disposed near the sheet holding portion of the rotating roller (seal roller), it is possible to prevent the filling material from spilling when supplying the filling material to the concave portion. Further, by allowing the filling nozzle to be inserted into the concave portion during the formation of the concave portion, even if the nozzle is thick, it can be inserted deeply into the container, and it is easy to cope with a filling material having a high viscosity. Further, in the present invention, the sheet is heated from the outside of the rotating roller before or after the sheet and the rotating roller (seal roller) come into contact with each other, and the sheet is heated to a temperature corresponding to the formation of the concave portion. be able to. For this reason, in a configuration in which the forming roller and the seal roller are used as a single rotating roller, even if the heating device is set to a high temperature corresponding to the formation of the concave portion, the sheet is supplied from the outside of the rotating roller (for forming and sealing). Is heated, so that the concave portion formed in the sheet does not weld to the concave portion of the rotating roller, and the concave portion can be easily peeled off from the concave portion.
また、 回転ローラの外部からシートを加熱することで、 シートの溶着部分を暖めるこ とができ、 確実に溶着させることができる。  In addition, by heating the sheet from the outside of the rotating roller, the welded portion of the sheet can be warmed, and the sheet can be reliably welded.
本発明の製造装置において、 前記シートを挟持して溶着する少なくとも一対の回転口 —ラは、 前記シー卜の流れ方向上流側に設けられて前記充填ノズルによる充填部分を残 して前記シートを溶着する一対の回転ローラと、 この回転ローラよりも前記シートの流 れ方向下流側に設けられて前記シートの充填部分を溶着する一対の回転ローラとを含む ことが望ましい。 In the manufacturing apparatus of the present invention, at least one pair of rotary ports for sandwiching and welding the sheet is provided on the upstream side in the flow direction of the sheet, and welds the sheet except for a portion filled by the filling nozzle.

特に、一次溶着のための回転ローラと二次溶着のための回転ローラを用いるとともに、 一次溶着のための回転ローラの未溶着部分の隙間を確保し、 充填ノズルを揷通させるこ とにより、 充填ノズルの先端を先行する一次溶着工程用の回転ローラと続く二次溶着用 の回転ローラとの間の領域に充填ノズルの先端を配置し、 一次溶着工程から送り出され たシートに形成された容器内に充填物を充填する。 これにより、 充填物は、 一次溶着工 程により一部を除き溶着されて形成された容器内に充填されるが、 この容器は未溶着の 部分があるため、 充填物は完全に密閉されず、 未溶着の部分にも充満した状態となる。 続いて、 二次溶着工程において、 包装体の未溶着の部分の溶着が行われる。 この際、 未 溶着の部分には充填物があり、 充填物を遮断するように溶着が行われる。  In particular, using a rotating roller for primary welding and a rotating roller for secondary welding, securing a gap between the unwelded portions of the rotating roller for primary welding, and passing the filling nozzle through to fill The tip of the nozzle is located in the area between the rotating roller for the primary welding process that precedes the rotating roller for the primary welding process and the rotating roller for the secondary welding that follows, and the inside of the container formed on the sheet sent out from the primary welding process Fill the filling. As a result, the filling material is filled into a container formed by welding except for a part in the primary welding process, but since the container has an unwelded portion, the filling material is not completely sealed, Unfilled portions are also filled. Subsequently, in the secondary welding step, the unwelded portion of the package is welded. At this time, there is a filler in the unwelded part, and the welding is performed so as to block the filler.
これにより、 充填物以外に空洞部分等がない完全充填の包装体を得ることができる。 本発明の製造装置において、 前記包装体の一方の成形体の凹部の前記フランジ部側の 一部は、 他方の成形体のフランジ部と対向配置され、 この他方の成形体のフランジ部と 溶着されない非溶着部となっており、 この非溶着部には、 開封用の切込みが形成され、 前記一対の回転ローラの前段には、 前記一方の成形体の原反となるシートに前記切込み を形成するための切込み形成手段が配置されていることが好ましい。  This makes it possible to obtain a completely filled package having no hollow portion other than the filler. In the manufacturing apparatus of the present invention, a part of the concave portion of one molded body of the package on the side of the flange portion is arranged to face the flange portion of the other molded body, and is not welded to the flange portion of the other molded body. An uncut portion is formed in the non-welded portion, and a notch for opening is formed in the non-welded portion, and the notch is formed in a sheet serving as a raw material of the one molded body in a stage preceding the pair of rotating rollers. Is preferably provided.

以下、 本発明の実施形態を図面に基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[包装体の構成] [Structure of package]
図 1には、 本実施形態の製造装置 1 (図 3参照） により製造される包装体 2が示され ている。  FIG. 1 shows a package 2 manufactured by the manufacturing apparatus 1 (see FIG. 3) of the present embodiment.
この包装体 2は、 例えば、 粘性調味料、 液体状の薬品等の流体状の物質や、 顆粒状の 物質などの充填物 9 (図 2 (A) 、 図 2 (B) 参照） 等を密封収納するものである。 図 2 (A) にも示すように、 包装体 2は、 凹部 2 1 1， 2 2 1を有する一対の成形体 2 1 , 2 2を備えている。 一対の成形体 2 1 , 2 2の凹部 2 1 1 , 2 2 1は互いに向き 合わせて配置されており、凹部 2 1 1 , 2 2 1の周縁部に形成されたフランジ部 2 1 2 , 2 2 2は溶着されている。 凹部 2 1 1， 2 2 1の形状は本実施形態では、 断面略半楕円 形状であり、 凹部 2 1 1 , 2 2 1を対向配置させた形状は断面略楕円形形状となってい る。  The package 2 seals, for example, a fluid substance such as a viscous seasoning or a liquid chemical, or a filler 9 (see FIGS. 2 (A) and 2 (B)) such as a granular substance. It is to be stored. As shown in FIG. 2 (A), the package 2 includes a pair of molded bodies 21 and 22 having recesses 2 1 1 and 2 2 1. The recesses 2 1 1, 2 2 1 of the pair of molded bodies 2 1, 2 2 are arranged facing each other, and the flanges 2 1 2, 2 formed on the peripheral edge of the recesses 2 1 1, 2 2 1 22 is welded. In the present embodiment, the shapes of the concave portions 2 1 1 and 2 2 1 are substantially semi-elliptical in cross section, and the shape in which the concave portions 2 1 1 and 2 2 1 are arranged to face each other has a substantially elliptical cross section.
また、 本実施形態では、 フランジ部 2 1 2 , 2 2 2の外形形状は、 矩形形状となって いる。  Further, in the present embodiment, the outer shape of the flange portions 2 1 2 and 2 2 2 is a rectangular shape.
一方の成形体 2 1の凹部 2 1 1のフランジ部 2 1 2側の一部は、 他方の成形体 2 2の フランジ部 2 2 2と対向配置し、 このフランジ部 2 2 2に溶着しない非溶着部 2 1 1 A となっている。  A part of the concave portion 2 1 1 of the molded body 2 1 on the side of the flange portion 2 1 2 is arranged so as to face the flange portion 2 2 2 of the other molded body 2 2, and is not welded to the flange portion 2 2 2. The welded portion is 2 11 A.
この非溶着部 2 1 1 Aの包装体外側面には、 この非溶着部 2 1 1 Aを跨るように切込 み 2 1 1 Bが形成されている。  A cut 211B is formed on the outer surface of the package of the non-welded portion 211A so as to straddle the non-welded portion 211A.
以上のような一方の成形体 2 1は、 包装体 2の外側から凹部 2 1 1をつぶす方向に手 で把持した際に、変形しない程度の硬さを有する硬質材料から構成されている。例えば、 一方の成形体 2 1はポリスチレンを主成分とする多層構造のシ一トから構成されており、 充填物 9と接する内側の層は、 低密度ポリエチレンとなっている。 One of the molded bodies 21 as described above is made of a hard material having such a hardness that it does not deform when grasped by hand from the outside of the package 2 in the direction of crushing the concave portion 211. For example, one molded body 21 is composed of a multi-layered sheet mainly composed of polystyrene. The inner layer in contact with filling 9 is low density polyethylene.
他方の成形体 2 2は把持力により変形する可撓性材料から構成されている。 例えば、 ポリエチレンを主成分とする多層構造のシートから構成されており、 流動性物質と接す る内側の層は、 直鎖状低密度ポリエチレンとなっている。  The other molded body 22 is made of a flexible material that is deformed by a gripping force. For example, it is composed of a multi-layered sheet mainly composed of polyethylene, and the inner layer in contact with the fluid substance is linear low-density polyethylene.
このような包装体 2から充填物 9を取り出す場合には、 非溶着部 2 1 1 Aを他方の成 形体 2 2側に折り曲げる。 すると、 切込み 2 1 1 Bが破断されて開口が形成される。 そ して、 他方の成形体 2 2の凹部 2 2 1を把持し、 押しつぶすと、 把持力が作用すること により他方の成形体 2 2の凹部 2 2 1は徐々に反転し、 図 2 (B) に示すように、 充填 物 9がすべて取り出された時点では、 他方の成形体 2 2の凹部 2 2 1は一方の成形体 2 1の凹部 2 1 1に密着する。 このことにより内部の充填物 9を完全に排出させることが できる。  When removing the filler 9 from such a package 2, the non-welded portion 211A is bent toward the other molded body 22 side. Then, the notch 2 11 1 B is broken to form an opening. Then, when the concave portion 22 1 of the other molded body 22 is gripped and crushed, the concave portion 22 1 of the other molded body 22 is gradually inverted due to the application of the gripping force. As shown in ()), when all of the fillers 9 are taken out, the recesses 22 1 of the other molded body 22 come into close contact with the recesses 21 1 of the one molded body 21. This allows the internal filling 9 to be completely discharged.

回収装置 19は、 包装体 2が打ち抜かれたシート 23， 24を巻き取り、 回収するも のであり、 巻き取りローラ 191を備えている。 本実施形態では切断手段 18の下方に 配置されている。  The collecting device 19 winds and collects the sheets 23 and 24 from which the package 2 has been punched, and includes a winding roller 191. In the present embodiment, it is arranged below the cutting means 18.
次に、以上のような製造装置 1を用いて、包装体 2を製造する方法について説明する。 まず、 シ一ト供給手段 11によりシート 23 , 24を回転ローラ 13， 14に供給す る （シート供給工程） 。 なお、 シート 23, 24が回転ローラ 13, 14に到達する前 に、 切込み形成手段 12によりシート 23に所定間隔で切込み 211 Bが形成される （ 切り込み形成工程） 。  Next, a method of manufacturing the package 2 using the manufacturing apparatus 1 as described above will be described. First, the sheets 23 and 24 are supplied to the rotating rollers 13 and 14 by the sheet supplying means 11 (sheet supplying step). Before the sheets 23 and 24 reach the rotating rollers 13 and 14, the notches 211B are formed at predetermined intervals in the sheet 23 by the notch forming means 12 (a notch forming step).
回転ローラ 13， 14表面にシート 23， 24がそれぞれ供給されると、 回転ローラ 13， 14内部に配置された加熱装置及び回転ローラ 13, 14外部に配置された加熱 装置 16によりシート 23， 24が加熱される （加熱工程） 。  When the sheets 23 and 24 are supplied to the surfaces of the rotating rollers 13 and 14, respectively, the sheets 23 and 24 are heated by the heating device arranged inside the rotating rollers 13 and 14 and the heating device 16 arranged outside the rotating rollers 13 and 14. It is heated (heating step).
さらに、 真空ポンプ 134の可動により回転ローラ 13， 14の窪み部 131, 14 1の通気孔 132から窪み部 131, 141内の空気が吸気される。 そして、 真空ボン プ 134により生じた吸引力によりシート 23, 24の一部が窪み部 131， 141内 に吸引され、 これにより凹部 211, 221が形成されることとなる（凹部形成工程）。 さらに、 回転ローラ 13， 14の回転に伴い、 まず凹部 211， 221よりもシート 供給方向先端側の部分が回転ローラ 13, 14に挟持され溶着される。 その後、 凹部 2 11, 221が対向配置され、さらに、回転ローラ 13， 14の回転に伴い凹部 211, 221よりもシート供給方向後端側の部分が挟持され、 溶着されて凹部 211， 221 が完全密封される （溶着工程） 。 なお、 凹部 211, 221よりもシート供給方向先端側の部分が回転ローラ 13， 1 4に挟持された後、 凹部 211， 221よりもシート供給方向後端側の部分が回転ロー ラ 13, 14に挟持されるまでの間に、 凹部 211, 221に充填ノズル 171から充 填物 9が供給される （充填工程） 。 なお、 この充填は連続的に行われてもよいし、 間欠 的に行われてもよい。 Further, the air in the depressions 131 and 141 is sucked from the ventilation holes 132 of the depressions 131 and 141 of the rotating rollers 13 and 14 by the operation of the vacuum pump 134. Then, the suction force generated by the vacuum pump 134 causes a part of the sheets 23, 24 to be sucked into the recessed portions 131, 141, whereby the recesses 211, 221 are formed (recess forming step). Further, as the rotating rollers 13 and 14 rotate, first, a portion on the leading end side in the sheet supply direction with respect to the concave portions 211 and 221 is nipped and welded by the rotating rollers 13 and 14. Thereafter, the concave portions 2 11 and 221 are arranged to face each other, and further, with the rotation of the rotating rollers 13 and 14, a portion on the rear end side in the sheet feeding direction with respect to the concave portions 211 and 221 is sandwiched and welded to complete the concave portions 211 and 221. It is sealed (welding process). After the portions on the leading end side in the sheet supply direction from the recesses 211 and 221 are sandwiched by the rotating rollers 13 and 14, the portions on the trailing end side in the sheet supply direction from the recesses 211 and 221 are placed on the rotating rollers 13 and 14. Until being sandwiched, the filling material 9 is supplied from the filling nozzle 171 to the concave portions 211 and 221 (filling step). This filling may be performed continuously or intermittently.
次に、 溶着されたシート 23 , 24は、 切断手段 18に供給される。 凹部 211， 2 21はローラ 181に形成された窪み部 182に収納され、 凹部 211， 221周縁部 (フランジ部 212， 222の外周） が打ち抜かれる （切断工程） 。 これにより包装体 2を得ることができる。  Next, the welded sheets 23 and 24 are supplied to the cutting means 18. The concave portions 211 and 221 are housed in the concave portion 182 formed in the roller 181, and the peripheral portions of the concave portions 211 and 221 (the outer periphery of the flange portions 212 and 222) are punched out (cutting step). Thereby, the package 2 can be obtained.
そして、 包装体 2は、 前述したように、 回収箱 151内に回収され、 また、 包装体 2 が打ち抜かれたシート 23， 24は回収装置 19に回収される。  Then, the package 2 is collected in the collection box 151 as described above, and the sheets 23 and 24 from which the package 2 is punched are collected in the collection device 19.
従って、 本実施形態によれば、 以下の効果を奏することができる。  Therefore, according to the present embodiment, the following effects can be obtained.
(卜 1)一対の回転ローラ 13, 14の表面で各シート 23, 24に凹部 211, 221 を形成するとともに、回転ローラ 13, 14によりシート 23， 24を挟持することで、 溶着する構成となっているので、シート 23, 24を予め筒状等に成形する必要がなく、 幅広の平坦なシ一ト 23， 24から包装体 2を成形することができる。  (1) The recesses 211 and 221 are formed in the sheets 23 and 24 on the surfaces of the pair of rotating rollers 13 and 14, and the sheets 23 and 24 are sandwiched by the rotating rollers 13 and 14 to be welded. Therefore, it is not necessary to form the sheets 23 and 24 into a tubular shape or the like in advance, and the package 2 can be formed from the wide and flat sheets 23 and 24.
(1-2) また、 回転ローラ 13， 14の回転に伴い凹部 211, 221のシート供給方向 先端側部分が挟持されて溶着され、 さらに、 凹部 211, 221同士が対向配置された 後、後端側部分が挟持されて溶着する。このように、本実施形態では、回転ローラ 13, 14の回転に伴って包装体 2を連続的に成形することができるため、 製造スピードを向 上させることができる。  (1-2) Also, with the rotation of the rotating rollers 13 and 14, the leading end portions of the concave portions 211 and 221 in the sheet feeding direction are nipped and welded, and furthermore, after the concave portions 211 and 221 are arranged to face each other, the rear end is formed. The side parts are pinched and welded. As described above, in the present embodiment, since the package 2 can be continuously formed with the rotation of the rotating rollers 13 and 14, the manufacturing speed can be improved.
(1-3) また、 シート 23, 24から包装体 2を打ち抜くための切断手段 18はローラ 1 81表面に抜き打ち刃 183が形成されたものであるため、 シート 23, 24の供給速 度に応じてローラ 181を回転させることで、 包装体 2の打ち抜きも連続的に行うこと ができる。 これにより製造スピードをさらに向上させることができる。  (1-3) Since the cutting means 18 for punching the package 2 from the sheets 23 and 24 has the punching blade 183 formed on the surface of the roller 181, the cutting means 18 depends on the supply speed of the sheets 23 and 24. By rotating the roller 181, the package 2 can be punched continuously. Thereby, the manufacturing speed can be further improved.
(1-4) また、 本実施形態では、 凹部 211, 221に充填物 9を供給した後、 凹部 21 1， 221よりもシート供給方向後端側部分を回転ローラ 13, 14により溶着する構 成であるため、 充填物 9を充填した後、 凹部 211， 221は、 すぐに密閉されること となる。 従って、 凹部 211， 221内の充填物 9が後工程においてこぼれる可能性が なく、 これにより凹部 211， 221内に満杯に充填物 9を供給することができる。(1-4) Further, in the present embodiment, after the filler 9 is supplied to the recesses 211 and 221, the rear end portion of the sheet feeding direction from the recesses 211 and 221 is welded by the rotating rollers 13 and 14. Therefore, the recesses 211 and 221 should be sealed immediately after filling with the filling material 9. It becomes. Therefore, there is no possibility that the filling material 9 in the concave portions 211 and 221 will be spilled in the subsequent process, and thus the filling material 9 can be fully supplied into the concave portions 211 and 221.
(1-5) さらに、 充填ノズル 171は、 回転ローラ 13, 14近傍に配置されているため 、 供給時に充填物 9がこぼれてしまうことを防止できる。 (1-5) Further, since the filling nozzle 171 is disposed near the rotating rollers 13 and 14, it is possible to prevent the filling material 9 from spilling during supply.
(卜 6) また、 回転ローラ 13, 14の内部にのみ加熱装置を配置した場合、 回転ローラ 13, 14内部の加熱装置では、 窪み部 131, 141内のシート 23, 24を凹部 2 11， 221成形に応じた温度まで充分に加熱することが困難であり、 シート 23, 2 4に凹部 211， 221を形成することができない場合がある。  (6) When the heating device is disposed only inside the rotating rollers 13, 14, the heating devices inside the rotating rollers 13, 14 make the sheets 23, 24 in the recesses 131, 141 into the concave portions 211, 221. In some cases, it is difficult to sufficiently heat the sheet to a temperature corresponding to the molding, and the recesses 211 and 221 cannot be formed in the sheets 23 and 24 in some cases.
これに対し、 本実施形態では、 回転ローラ 13, 14の外部に加熱装置 16を配置し ているため、 加熱装置 16により、 シート 23, 24を凹部 211, 221成形に応じ た温度に暖めることができ、凹部 211， 221を確実に成形することができる。また、 加熱装置 16は回転ローラ 13, 14の外部に配置されているため、 加熱装置 16を凹 部 211， 221成形に応じた高い温度に設定しても、 回転ローラ 13, 14の窪み部 131， 141に凹部 211, 221が溶着してしまうことがなく、 窪み部 131, 1 41から凹部 211， 221を容易に剥離させることができる。  In contrast, in the present embodiment, since the heating device 16 is disposed outside the rotating rollers 13 and 14, the heating devices 16 can heat the sheets 23 and 24 to a temperature corresponding to the formation of the recesses 211 and 221. As a result, the concave portions 211 and 221 can be reliably formed. Further, since the heating device 16 is disposed outside the rotating rollers 13 and 14, even if the heating device 16 is set to a high temperature according to the formation of the concave portions 211 and 221, the concave portions 131 of the rotating rollers 13 and 14 can be used. , 141 are not welded to the recesses 211, 221 and the recesses 211, 221 can be easily separated from the recesses 131, 141.
また、回転ローラ 13, 14の外部に加熱装置 16を配置しているため、シート 23, 24の溶着部分も暖めることができ、 確実に溶着させることができる。 特に、 本実施形 態では、 加熱装置 16は、 回転ローラ 13, 14の表面の 1Z4以上をも覆うような構 造であるため、 シート 23 , 24の溶着部分を確実に暖めることができる。  In addition, since the heating device 16 is disposed outside the rotating rollers 13 and 14, the welded portions of the sheets 23 and 24 can be warmed and can be reliably welded. In particular, in the present embodiment, since the heating device 16 has a structure that also covers 1Z4 or more of the surface of the rotating rollers 13 and 14, the welded portions of the sheets 23 and 24 can be reliably heated.
(1-7) さらに、 本実施形態で製造された包装体 2は、 凹部 211, 221と、 フランジ 部 212, 222とを対向配置させたものであり、 フランジ部 212， 222を中心と して上下略対称のものである。したがって、本実施形態の製造方法及び製造装置 1では、 意匠性の高い包装体 2を得ることができる。  (1-7) Further, the package 2 manufactured in the present embodiment has the concave portions 211 and 221 and the flange portions 212 and 222 opposed to each other. It is almost symmetrical up and down. Therefore, in the manufacturing method and the manufacturing apparatus 1 of the present embodiment, the package 2 having high designability can be obtained.
(1-8)本実施形態の製造装置 1では、 回転ローラ 13, 14の前段に切込み 211 Bを 形成するための切込み形成手段 12が配置されているので、 包装体製造工程において、 切込み 211 Bを形成することができる。  (1-8) In the manufacturing apparatus 1 of the present embodiment, since the notch forming means 12 for forming the notch 211B is arranged at the previous stage of the rotating rollers 13 and 14, the notch 211B is formed in the package manufacturing process. Can be formed.
なお、 本発明は前述の実施形態に限定されるものではなく、 本発明の目的を達成でき る範囲での変形、 改良等は本発明に含まれるものである。 前記実施形態では、 製造装置 1により製造される包装体 2は、 切込み 2 1 1 Bで非溶 着部 2 1 1 Aを切断し、 開封するものであつたが、 本発明の製造装置は、 このような開 封方式の包装体 2を製造するものに限られない。 例えば、 図 5に示すように、 一方の成 形体 4 1と他方の成形体 4 2の溶着されたフランジ部 4 1 2， 4 2 2を引き剥がすこと で、 開封する方式の包装体 4を製造する製造装置であってもよい。 この包装体 4のフラ ンジ部 4 1 2， 4 2 2の隅部には、 互いに溶着されていないタブ部 4 1 2 A, 4 2 2 A が形成されており、 このタブ部 4 1 2 A, 4 2 2 Aを腿し、 引き剥がすことで、 包装 体 4が開封される。 It should be noted that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved. In the above-described embodiment, the package 2 manufactured by the manufacturing apparatus 1 cuts the non-welded portion 211A with the cut 211B and opens the package.However, the manufacturing apparatus of the present invention includes: The present invention is not limited to the production of such an open package 2. For example, as shown in FIG. 5, the unsealed package 4 is manufactured by peeling off the welded flange portions 4 1 2 and 4 2 2 of one molded body 41 and the other molded body 42. Manufacturing apparatus. At the corners of the flanges 4 12 and 4 22 of the package 4, tabs 4 12 A and 4 22 A which are not welded to each other are formed. , 4 22 A is thighed and peeled off, and the package 4 is opened.
この場合には、 切込み形成手段に変えて、 製造装置にタブ部を形成するためのタブ部 形成手段を設ければよい。  In this case, instead of the notch forming means, a tab forming means for forming a tab in the manufacturing apparatus may be provided.
また、 前記実施形態では、 製造装置 1は切込み形成手段 1 2を備えるものとしたが、 切込み形成手段 1 2を備えない構成としてもよい。 例えば、 包装体を製造した後に別ェ 程で切込みを形成する場合には、 切込み形成手段 1 2は不要である。  Further, in the above-described embodiment, the manufacturing apparatus 1 includes the cut forming means 12, but may be configured not to include the cut forming means 12. For example, when the cut is formed in a separate step after the production of the package, the cut forming means 12 is unnecessary.
さらに、 前記実施形態では、 非溶着部 2 1 1 Aの包装体外側面に切込み 2 1 1 Bを形 成したが、 非溶着部 2 1 1 Aの包装体内側面に切込みを形成してもよい。  Furthermore, in the above-described embodiment, the cuts 211B are formed on the outer surface of the package of the non-welded portion 211A, but the cuts may be formed on the inner surface of the package of the non-welded portion 211A.
また、 前記実施形態では、 回転ローラ 1 3 , 1 4の外部に設けられる加熱装置は加熱 装置 1 6のみであつたが、 これに限らず、 図 6に示すような予熱用の加熱装置 3 0を用 いてもよい。 この予熱用の加熱装置 3 0は、 回転ローラ 1 3， 1 4と切込み形成手段 1 2との間にシート 2 3， 2 4を挟むように配置されている。 このような予熱用の加熱装 置 3 0を設けることで、 シート 2 3 , 2 4に凹部 2 1 1， 2 2 1を確実に形成すること ができる。  Further, in the above embodiment, the heating device provided outside the rotary rollers 13 and 14 is only the heating device 16. However, the present invention is not limited to this, and the heating device 30 for preheating as shown in FIG. May be used. The heating device 30 for preheating is arranged so that the sheets 23 and 24 are sandwiched between the rotating rollers 13 and 14 and the cut forming means 12. By providing such a heating device 30 for preheating, the concave portions 2 1 1 and 2 2 1 can be reliably formed in the sheets 23 and 24.
また、 図 6に示すように、 一対の回転ローラ 1 3 , 1 4の後段に、 更に一対の回転口 —ラであるシールドラム 3 1を配置してもよい。 このシールドラム 3 1の表面には凹部 2 1 1 , 2 2 1に応じた窪み部 3 1 1が形成されている。 このようなシールドラム 3 1 を配置することで、 シート 2 3 , 2 4の溶着部分をより強固に確実に溶着することがで きるとともに、 溶着シールのタイミングを回転ローラ 1 3 , 1 4と異なるものとし、 充 填物 9の封入シールを確実に行うことができる。  Further, as shown in FIG. 6, a seal drum 31 which is a pair of rotary rollers may be disposed at a stage subsequent to the pair of rotary rollers 13 and 14. The surface of the seal drum 31 has a recess 311 corresponding to the recesses 2 1 1 and 2 2 1. By arranging such a seal drum 31, the welded portions of the sheets 23, 24 can be more firmly and reliably welded, and the timing of the weld seal is different from that of the rotating rollers 13, 14. As a result, the sealing of the filling material 9 can be reliably performed.
更に、 前記実施形態では一対の回転ローラ 1 3， 1 4が成形ローラとシールローラと を完全に兼ねるものであつたが、 これらの機能を部分的に独立させてもよい。 Further, in the above embodiment, the pair of rotating rollers 13 and 14 are formed by the forming roller and the seal roller. Although these functions are completely used, these functions may be partially independent.
すなわち、 図 6において、 回転ローラ 1 3， 1 4は凹部 2 1 1， 2 2 1の成形と包装 体の流れ方向外周部の溶着を行い、 充填物 9を充填するための部分は未溶着とする （一 次溶着工程） 。 この場合には、 充填工程においては充填物 9が完全に密閉されず、 充填 物 9の一部は後段のシールドラム 3 1に移動し、 未溶着の部分に充填物 9がある部分で (充填物 9を遮断するように） 溶着が行われる （二次溶着工程） 。 これにより、 充填物 9以外の空洞部分等がない完全充填の包装体を得ることができる。  That is, in FIG. 6, the rotating rollers 13 and 14 form the recesses 2 11 and 2 21 and weld the outer periphery of the package in the flow direction, and the portion for filling the filling 9 is not welded. (Primary welding process). In this case, in the filling step, the filling 9 is not completely sealed, and a part of the filling 9 moves to the subsequent seal drum 31 and the portion where the filling 9 is present in the unwelded portion (the filling Welding is performed (so as to block the object 9) (secondary welding step). This makes it possible to obtain a completely filled package having no hollow portion other than the filler 9.
このような溶着を行う場合、 回転ローラ 1 3， 1 4の互いの対向部分の、 未溶着とす る部分の断面形状は、溶着性を考慮してやや扁平な形状とすることが望ましい。そして、 未溶着とする部分の回転ローラ 1 3 , 1 4の互いの対向部分の隙間をなるベく大きくと り、 この隙間に充填ノズル 1 Ί 1を揷通させ、 その先端を回転ローラ 1 3， 1 4とシ一 ルドラム 3 1との間の領域に配置させる。 このように延長された充填ノズリレ 1 7 1によ り、 充填物 9は回転ローラ 1 3 , 1 4による一次溶着により形成された容器、 つまりシ —トの流れ方向の側方と横断方向の中間部を除く部分とが溶着された容器の内部に充填 される。そして、充填物 9は充填ノズル 1 7 1からの充填圧力により容器内に行き渡り、 一部は未溶着部分に進入する。 この状態で、 シールドラム 3 1による二次溶着が行われ れば、 前述した充填物 9の遮断による完全充填が行われる。  When performing such welding, it is desirable that the cross-sectional shape of the unwelded portion of the opposing portions of the rotating rollers 13 and 14 be slightly flat in consideration of the welding property. Then, the gap between the portions of the rotating rollers 13 and 14 that are not to be welded is set to be as large as possible, and the filling nozzle 1 is passed through this gap, and the tip of the rotating roller 13 is , 14 and the seal drum 31. Due to the filling nozzle 17 1 extended in this way, the filling 9 becomes a container formed by primary welding by the rotating rollers 13, 14, that is, an intermediate portion between the side and the cross direction of the sheet flow direction. The part excluding the part is filled inside the welded container. Then, the filling material 9 spreads throughout the container by the filling pressure from the filling nozzle 171, and a part of the filling material 9 enters the unwelded portion. In this state, if the secondary welding by the seal drum 31 is performed, the above-mentioned complete filling by the interruption of the filling 9 is performed.
従って、 この方法により、 包装体本体部を形成するための大部分のシール （一次溶着 ) と、 充填物 9の充填と、 完全密封のためのシール （二次溶着） とを、 それぞれ分離し て行うことができるため、連続製造性、溶着の完全性、 1 0 0 %の完全充填性を同時に、 かつ容易に達成することができる。  Therefore, according to this method, most of the seal (primary welding) for forming the package body, the filling of the filler 9 and the seal (secondary welding) for complete sealing are separated from each other. Therefore, continuous manufacturability, completeness of welding, and complete filling of 100% can be simultaneously and easily achieved.
また、 本発明の製造方法により製造される包装体の形状は、 前記実施形態の包装体 2 の形状には限られない。 例えば、 前記実施形態では、 凹部 2 1 1 , 2 2 1を対向配置さ せた形状を断面略楕円形状としたが、 断面矩形形状としてもよく、 また、 断面八ート型 形状としてもよい。 また、 前記実施形態では、 フランジ部 2 1 2 , 2 2 2の外形形状を 矩形形状としたが、 これに限られず、 例えば、 円形形状としてもよい。 産業上の利用可能性 本発明は、 包装体の製造方法及び製造装置に関し、 粘性調味料、 液状の薬品等の流動 性物質を充填するための包装体の製造に利用できる。 Further, the shape of the package manufactured by the manufacturing method of the present invention is not limited to the shape of the package 2 of the embodiment. For example, in the above-described embodiment, the shape in which the concave portions 211 and 221 are opposed to each other has a substantially elliptical cross-section, but may have a rectangular cross-section, or may have an octagonal cross-section. Further, in the above-described embodiment, the outer shape of the flange portions 212 and 222 is a rectangular shape. However, the present invention is not limited to this. For example, the outer shape may be a circular shape. Industrial applicability The present invention relates to a method and an apparatus for manufacturing a package, and can be used for manufacturing a package for filling a fluid substance such as a viscous seasoning and a liquid chemical.
