Description

本発明は、流動体、粘稠（ねんちゅう）体、粉体等を充填しヒートシール部で密封した密封袋とその製造方法及び装置に関する。   The present invention relates to a sealed bag filled with a fluid, a viscous body, powder, or the like and sealed with a heat seal portion, and a method and apparatus for manufacturing the same.

従来、スープ、ソースのような流動体、練りからしのような粘稠体等を充填し密封するには、フィルム状包材を長さ方向に送りながら同方向に平行な線上で折り返しつつ、同方向に伸びる縦ヒートシール部を設けて筒状の重畳体を形成し、同方向に交差する方向に伸びる横ヒートシール部により重畳体を下流側で閉じ、上流側から内容物を重畳体内に充填し、他の横ヒートシール部により重畳体を上流側で閉じて上下の横ヒートシール部間に内容物を密封し、しかる後重畳体から密封袋を横ヒートシール部上で切り離すようにしている（例えば、特許文献１、２参照。）。   Traditionally, to fill and seal fluids such as soups and sauces, viscous materials such as kashikara, while folding the film-like wrapping material along the line parallel to the same direction, A vertical heat seal portion extending in the same direction is provided to form a cylindrical superposed body, the superposed body is closed downstream by a horizontal heat seal portion extending in the direction intersecting the same direction, and the contents are put into the superposed body from the upstream side. Fill and close the superposed body on the upstream side with another horizontal heat seal part to seal the contents between the upper and lower horizontal heat seal parts, and then detach the sealing bag from the superposed body on the horizontal heat seal part. (For example, refer to Patent Documents 1 and 2.)

図１（Ｂ）及び図２（Ｂ）はこのようにして得られた密封袋の一例を示す。密封袋１を構成するフィルム状包材１５の四辺は縦ヒートシール部２，３と横ヒートシール部４，５でそれぞれ閉じられ、内部にはスープ等の内容物Ａが密封されている。この密封袋１は、例えば弁当に添付され、弁当を購入した者により喫食に際して開封され使用される。   FIG. 1 (B) and FIG. 2 (B) show an example of the sealed bag thus obtained. The four sides of the film-like packaging material 15 constituting the sealing bag 1 are closed by the vertical heat seal portions 2 and 3 and the horizontal heat seal portions 4 and 5, respectively, and the contents A such as soup are sealed inside. The sealed bag 1 is attached to a lunch box, for example, and is opened and used by a person who purchased the lunch box at the time of eating.

また、従来、密封袋の角が使用者の手に当たっても使用者に不快感を与えないようにするため、密封袋の辺や角にパイプ状又はヒレ状の非ヒートシール部を設けることが提案されている（例えば、特許文献３、４参照。）。   Conventionally, in order to prevent the user from feeling uncomfortable even if the corner of the sealed bag hits the user's hand, it has been proposed to provide a pipe-shaped or fin-shaped non-heat-sealed portion on the side or corner of the sealed bag. (See, for example, Patent Documents 3 and 4).

特開２００１−３５４２１０号公報JP 2001-354210 A 特開２００２−１０４３１０号公報JP 2002-104310 A 特開２００７−９９３６４号公報JP 2007-99364 A 特開２００９−７３５０４号公報JP 2009-73504 A

図１（Ｂ）に示したように、従来の密封袋１は、折り返し部と反対側のヒートシール部２では非ヒートシール部１３が耳状に形成されるが、折り返し部では縦横のヒートシール部３，４，５の存在により尖った角部６が形成される。この角部６が使用者に当たると使用者に不快感を与えることになる。また、この角部６が他の包装品等に当たると、他の包装品等の包装が傷付けられるおそれがある。   As shown in FIG. 1B, the conventional sealing bag 1 has a non-heat-sealed portion 13 formed in an ear shape in the heat-sealed portion 2 on the opposite side to the folded portion, but the vertical and horizontal heat seals are formed in the folded portion. A sharp corner 6 is formed by the presence of the parts 3, 4, 5. When the corner 6 hits the user, the user is uncomfortable. Moreover, when this corner | angular part 6 hits other packaged goods etc., there exists a possibility that packaging of other packaged goods etc. may be damaged.

上述したように密封袋の辺や角にパイプ状又はヒレ状の非ヒートシール部を設けることで密封袋の尖った角部は解消されるが、引用文献３の密封袋はヒレ状又はパイプ状の非ヒートシール部が天側と底側とにおけるヒートシール部によって潰れているので、天側及び底側の各角には尖った角部が依然として存在し、根本的な解決策とはなっていない。   As described above, by providing a pipe-shaped or fin-shaped non-heat-sealed portion at the sides or corners of the sealing bag, the sharp corners of the sealing bag are eliminated, but the sealing bag of the cited document 3 is fin-shaped or pipe-shaped. The non-heat-sealed part is crushed by the heat-sealed parts on the top and bottom sides, so there are still sharp corners at each corner on the top and bottom sides, which is a fundamental solution. Absent.

引用文献４の袋にもヒレ状の非ヒートシール部が形成されるが、引用文献４の図１に示されるように、二枚のフィルムの両側にヒレ状の非ヒートシール部が正確に形成されるよう二枚のフィルムを重ねてヒートシールするのは面倒である。また、引用文献４の図８に示される袋はその一辺にヒレ状の非ヒートシール部を有するのみであり、その対向辺上には尖った角部が依然として存在し、根本的な解決策とはなっていない。   Although the fin-shaped non-heat-sealed portion is also formed in the bag of the cited document 4, as shown in FIG. 1 of the cited document 4, the fin-shaped non-heat-sealed portion is accurately formed on both sides of the two films. It is cumbersome to heat-seal the two films as they are. Further, the bag shown in FIG. 8 of the cited document 4 has only a fin-like non-heat-sealed portion on one side, and a sharp corner portion still exists on the opposite side, and the fundamental solution is It is not.

Specifically, in FIG. 1 (A), the heat seal portion 9 along the folded portion is such that one pipe-like non-heat seal portion 12 that penetrates between both ends of the one side remains in the folded portion on one side. The heat seal portion 8 on the side facing the folded portion is formed so that two fin-like non-heat seal portions 13 remain, and two horizontal strips perpendicular to the vertical heat seal portions 8 and 9 are left. The heat seal portions 10 and 11 are formed such that both ends leave the non-heat seal portions 12 and 13. The non-heat seal portions 12 and 13 are formed narrower than the width of the heat seal portions 8 and 9. The pipe-shaped non-heat-sealed portion 12 and the fin-shaped non-heat-sealed portion 13 thus provided eliminate the sharp edges from the four corner portions 14 of the sealing bag 7, and as a result, the corner portions 14 of the sealing bag 7. Even if it hits the user's skin, the user will not feel uncomfortable or uncomfortable.

次に、上記密封袋の製造方法及び装置について説明する。   Next, the manufacturing method and apparatus of the said sealing bag are demonstrated.

（１）図３及び図４に示すように、フィルム状包材１５を巻き取ったロール（図示せず）からフィルム状包材１５が繰り出され、この繰り出されたフィルム状包材１５が各種ガイドローラ１６，１７により長さ方向に案内される。フィルム状包材１５は長さ方向に送られながらガイドバー１８により同方向に平行な線上で折り返され二つ折りの重畳体とされる。   (1) As shown in FIGS. 3 and 4, the film-shaped packaging material 15 is fed out from a roll (not shown) around which the film-shaped packaging material 15 is wound, and the fed film-shaped packaging material 15 serves as various guides. It is guided in the length direction by rollers 16 and 17. The film-like packaging material 15 is folded back on a line parallel to the same direction by the guide bar 18 while being sent in the length direction to form a bi-fold superposed body.

（２）二つ折りされたフィルム状包材１５は、その片側の折り返し部と反対側の開放部をそれぞれ縦ヒートシール部９，８によりシールされ、扁平な筒状の重畳体とされる。   (2) The film-shaped packaging material 15 folded in half is sealed with the longitudinal heat seal portions 9 and 8 at the opening portion on the opposite side to the folded portion on one side to form a flat cylindrical superposed body.

この二本の縦ヒートシール部９，８は、重畳体の両側が表裏からヒートシール車２０ａ，２０ｂ，２０ｃ（２０ｄは図示せず）に挟まれることにより形成される。各ヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄには、図示しない電気ヒータが組み込まれ、重畳体に接する箇所が加熱されるようになっている。   The two vertical heat seal portions 9 and 8 are formed by sandwiching both sides of the superposed body from the front and back of the heat seal wheels 20a, 20b and 20c (20d not shown). Each heat-sealed vehicle 20a, 20b, 20c, 20d incorporates an electric heater (not shown) so that a portion in contact with the superimposed body is heated.

二本の回転軸２１の両側にそれぞれ一つずつ固定されたヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄが、重畳体の表裏両面側に一対ずつ配置され、対向するヒートシール車２０ａ，２０ｃ間に重畳体の開放部が挟み込まれ、対向するヒートシール車２０ｂ，２０ｄ間に重畳体の折り返し部が挟み込まれる。また、ヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄは、重畳体の両側の折り返し部と開放部にそれぞれ上記非ヒートシール部１２，１３が生じるように重畳体の両側よりやや内側に配置される。   A pair of heat seal wheels 20a, 20b, 20c, and 20d, which are respectively fixed on both sides of the two rotating shafts 21, are disposed on both the front and back sides of the superimposed body, and between the opposed heat seal wheels 20a and 20c. The opening part of the superposed body is sandwiched, and the folded part of the superposed body is sandwiched between the opposed heat seal wheels 20b, 20d. Further, the heat seal wheels 20a, 20b, 20c, and 20d are arranged slightly inside the both sides of the superimposed body so that the non-heat seal parts 12 and 13 are generated in the folded portions and the open portions on both sides of the superimposed body, respectively.

ヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄの回転軸２１が駆動され図４中矢印方向に回転することにより、重畳体の両側にはヒートシール部９，８が形成され、同時に折り返し部側に長さ方向に貫通するパイプ状の非ヒートシール部１２が形成され、開放部側にはヒレ状の非ヒートシール部１３が形成される。   When the rotary shaft 21 of the heat seal wheels 20a, 20b, 20c, and 20d is driven and rotated in the direction of the arrow in FIG. 4, heat seal portions 9 and 8 are formed on both sides of the superimposed body, and at the same time, the heat seal portions 9 and 8 are long. A pipe-like non-heat seal part 12 penetrating in the vertical direction is formed, and a fin-like non-heat seal part 13 is formed on the open side.

ヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄは連続回転し、重畳体はヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄ間を連続走行することにより両側に連続的に縦ヒートシール部９，８が形成される。もちろん、ヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄに代えて板状のヒートシール盤を用いることも可能である。その場合は、縦ヒートシール部９，８を間欠的に形成するので、重畳体もヒートシール盤間を間欠走行することになる。   The heat seal wheels 20a, 20b, 20c, and 20d rotate continuously, and the superimposed body continuously travels between the heat seal wheels 20a, 20b, 20c, and 20d, so that the vertical heat seal portions 9 and 8 are continuously formed on both sides. The Of course, it is also possible to use a plate-like heat sealing board instead of the heat sealing wheels 20a, 20b, 20c, 20d. In that case, since the vertical heat seal portions 9 and 8 are formed intermittently, the superimposed body also runs intermittently between the heat seal boards.

（３）両側が縦ヒートシール部９，８で閉じられた重畳体は、その長さ方向に交差する方向に伸びる横ヒートシール部２２により下流側で閉じられる。横ヒートシール部２２は図１（Ａ）に示す上下の横ヒートシール部１１，１０が重畳体の長さ方向に連なった形状及び大きさに形成される。   (3) The superposed body whose both sides are closed by the vertical heat seal portions 9 and 8 is closed on the downstream side by the horizontal heat seal portion 22 extending in the direction intersecting the length direction. The horizontal heat seal part 22 is formed in a shape and size in which the upper and lower horizontal heat seal parts 11 and 10 shown in FIG.

この横ヒートシール部２２は、重畳体の両側が表裏から一対のヒートシールローラ２３ａ，２３ｂに挟まれることにより形成される。一対のヒートシールローラ２３ａ，２３ｂはそれぞれ回転軸２４に固定され、上記ヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄよりも下流側において重畳体を表裏から挟むように対向配置される。   The horizontal heat seal portion 22 is formed by sandwiching both sides of the superimposed body from the front and back between a pair of heat seal rollers 23a and 23b. The pair of heat seal rollers 23a and 23b are fixed to the rotary shaft 24, respectively, and are arranged opposite to each other so that the superimposed body is sandwiched from the front and back sides of the heat seal wheels 20a, 20b, 20c and 20d.

各ヒートシールローラ２３ａ，２３ｂの表面には横ヒートシール部２２に対応してヒートシールバー２５が回転軸２４と平行に固定される。ヒートシールバー２５は密封袋７の長さに応じてヒートシールローラ２３ａ，２３ｂの表面に回転軸２４と平行に一本又は複数本固定される。各ヒートシールローラ２３ａ，２３ｂには、図示しない電気ヒータが組み込まれ、各ヒートシールバー２５が加熱されるようになっている。また、ヒートシールバー２５はヒートシールローラ２３ａ，２３ｂの表面に固定ネジ等により着脱可能に固定され、密封袋７の幅に応じて適宜交換可能である。   A heat seal bar 25 is fixed to the surface of each heat seal roller 23 a, 23 b in parallel with the rotary shaft 24 corresponding to the horizontal heat seal portion 22. One or a plurality of heat seal bars 25 are fixed to the surfaces of the heat seal rollers 23 a and 23 b in parallel with the rotary shaft 24 according to the length of the sealing bag 7. Each heat seal roller 23a, 23b incorporates an electric heater (not shown) so that each heat seal bar 25 is heated. The heat seal bar 25 is detachably fixed to the surfaces of the heat seal rollers 23 a and 23 b with fixing screws or the like, and can be appropriately replaced according to the width of the sealing bag 7.

ヒートシールローラ２３ａ，２３ｂは、重畳体の両側の折り返し部と開放部にそれぞれ形成された上記非ヒートシール部１２，１３をヒートシールしないように形成される。すなわち、ヒートシールバー２５は、望ましくはその長さが両側の縦ヒートシール部９，８の領域内に留まるように形成される。食み出たとしても両側の非ヒートシール部１２，１３が残るように形成される。   The heat seal rollers 23a and 23b are formed so as not to heat seal the non-heat seal portions 12 and 13 formed on the folded portion and the open portion on both sides of the superimposed body, respectively. That is, the heat seal bar 25 is preferably formed so that its length remains in the region of the vertical heat seal portions 9 and 8 on both sides. Even if it protrudes, it forms so that the non-heat seal parts 12 and 13 of both sides may remain.

ヒートシールローラ２３ａ，２３ｂの回転軸２４が駆動され図４中矢印方向に回転することにより、重畳体の下流側には横ヒートシール部２２が形成される。   When the rotating shaft 24 of the heat seal rollers 23a and 23b is driven and rotated in the direction of the arrow in FIG. 4, a horizontal heat seal portion 22 is formed on the downstream side of the superimposed body.

ヒートシールローラ２３ａ，２３ｂは連続回転し、重畳体はヒートシールローラ２３ａ，２３ｂ間を連続走行することにより一密封袋７分のピッチごとに横ヒートシール部２２で閉じられる。もちろん、ヒートシールローラ２３ａ，２３ｂに代えて一対の板状のヒートシール盤を用いることも可能である。その場合は、重畳体を間に挟んで一対のヒートシール盤を間欠的に接離運動させ、重畳体をヒートシール盤間で間欠走行させることになる。   The heat seal rollers 23a and 23b are continuously rotated, and the superposed body is continuously closed between the heat seal rollers 23a and 23b by the transverse heat seal portion 22 every pitch of 7 minutes for one sealed bag. Of course, it is also possible to use a pair of plate-like heat seal boards instead of the heat seal rollers 23a and 23b. In that case, a pair of heat seal boards are intermittently moved apart from each other with the superposed body interposed therebetween, and the superposed body is intermittently run between the heat seal boards.

（４）重畳体の下流側が横ヒートシール部２２で閉じられると、この横ヒートシール部２２の上に液状の内容物Ａが流入する。   (4) When the downstream side of the superposed body is closed by the horizontal heat seal portion 22, the liquid content A flows into the horizontal heat seal portion 22.

内容物Ａを供給する導管２６は重畳体間に侵入して左右のヒートシール車２０ａ，２０ｂの間をヒートシールローラ２３ａ，２３ｂへと伸び、その先端のノズル口２６ａが一対のヒートシールローラ２３ａ，２３ｂのヒートシールバー２５，２５同士が対向する箇所に向かって開口している。内容物Ａはノズル口２６ａから一定流量で連続的に流出し、先行する横ヒートシール部２２の上に内容物Ａが溜まると、図４に示すように、ヒートシールバー２５，２５同士が対向して液体を上下に分断するように重畳体に横ヒートシール部２２を形成する。   The conduit 26 for supplying the contents A enters between the overlapping bodies and extends to the heat seal rollers 23a and 23b between the left and right heat seal wheels 20a and 20b, and the nozzle port 26a at the tip thereof is a pair of heat seal rollers 23a. , 23b of the heat seal bars 25, 25 are opened toward the opposite positions. The content A continuously flows out from the nozzle port 26a at a constant flow rate, and when the content A accumulates on the preceding horizontal heat seal portion 22, the heat seal bars 25 and 25 face each other as shown in FIG. Then, the horizontal heat seal portion 22 is formed on the superposed body so as to divide the liquid vertically.

この実施の形態１では内容物Ａは連続的に吐出されるが、横ヒートシール部２２が形成される都度一定量ずつ間欠的に充填するようにしてもよい。   In the first embodiment, the content A is continuously discharged, but may be filled intermittently by a certain amount each time the horizontal heat seal portion 22 is formed.

（５）重畳体における内容物が充填された箇所が密封袋７の一ピッチ分だけ降下すると、ヒートシールローラ２３ａ，２３ｂ上の次のヒートシールバー２５，２５同士が重畳体の上流側に他の横ヒートシール部２２を形成する。これにより重畳体に内容物を密封した密封袋７が連続的に形成される。   (5) When the portion filled with the contents in the superposed body is lowered by one pitch of the sealing bag 7, the next heat seal bars 25, 25 on the heat seal rollers 23a, 23b are located on the upstream side of the superposed body. The horizontal heat seal portion 22 is formed. Thereby, the sealing bag 7 which sealed the content in the superimposition body is formed continuously.

他の横ヒートシール部２２は内容物Ａが液体である場合、上述したように充填された内容物の自由表面からやや下方に形成されるので、密封袋７内への空気の混入が防止される。   When the content A is a liquid, the other horizontal heat seal portion 22 is formed slightly below the free surface of the filled content as described above, so that air can be prevented from entering the sealing bag 7. The

（６）ヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄ及びヒートシールローラ２３ａ，２３ｂの回転により、密封袋７が重畳体に連続的に形成され、ヒートシールローラ２３ａ，２３ｂよりも下流側において横ヒートシール部２２上で切り離され、個々の密封袋７とされる。この密封袋７の切り離しは、ヒートシールローラ２３ａ，２３ｂよりも下流側に設置された切り離し手段であるロータリカッター２７により行われる。ロータリカッター２７は回転刃２７ａとこの回転刃２７ａに対向する固定刃２７ｂとを有する。回転刃２７ａは固定刃２７ｂとの間で重畳体を挟み込む剪断作用により、重畳体から密封袋７を横ヒートシール部２２の上で切り離すようになっている。ロータリカッター２７の回転刃２７ａは重畳体から密封袋７を横ヒートシール部２２の上で切り離す時点でのみ回転する。   (6) By the rotation of the heat seal wheels 20a, 20b, 20c, and 20d and the heat seal rollers 23a and 23b, the sealing bag 7 is continuously formed on the superposed body, and the lateral heat is provided downstream of the heat seal rollers 23a and 23b. It cuts off on the seal | sticker part 22 and it is set as each sealing bag 7. FIG. The sealing bag 7 is separated by a rotary cutter 27 which is a separating means installed downstream of the heat seal rollers 23a and 23b. The rotary cutter 27 has a rotary blade 27a and a fixed blade 27b facing the rotary blade 27a. The rotary blade 27a separates the sealing bag 7 from the superposed body on the horizontal heat seal portion 22 by a shearing action that sandwiches the superposed body with the fixed blade 27b. The rotary blade 27a of the rotary cutter 27 rotates only when the sealing bag 7 is separated from the superposed body on the horizontal heat seal portion 22.

もちろん、回転刃２７ａは重畳体の走行と同期的に連続回転させて重畳体から密封袋７を横ヒートシール部２２の上で切り離すようにしてもよい。また、このロータリカッター２７に代えて例えばギロチン式の切断機を設けることも可能である。この切断機は重畳体が密封袋７のピッチごとに間欠送りされる場合に適する。   Of course, the rotary blade 27a may be continuously rotated synchronously with the traveling of the superposed body to separate the sealing bag 7 from the superposed body on the horizontal heat seal portion 22. Further, instead of the rotary cutter 27, for example, a guillotine type cutting machine can be provided. This cutting machine is suitable when the superimposed body is intermittently fed every pitch of the sealing bag 7.

＜実施の形態２＞
図５に示すように、この密封袋２９は、実施の形態１の場合と同様に、一辺が折り返し部であり、三辺が開放縁であるフィルム状包材１５（図２参照）の重畳体で形成され、折り返し部に対向する辺の開放縁がヒートシール部８で閉じられる。このヒートシール部８は、実施の形態１と同様に、ヒレ状の非ヒートシール部１３が残るように形成される。 <Embodiment 2>
As shown in FIG. 5, as in the case of the first embodiment, the sealing bag 29 is a superposed body of the film-like packaging material 15 (see FIG. 2) in which one side is a folded portion and three sides are open edges. The open edge of the side facing the folded portion is closed by the heat seal portion 8. The heat seal portion 8 is formed so that the fin-like non-heat seal portion 13 remains as in the first embodiment.

この密封袋２９の折り返し部に交差する方向における二辺の開放縁は、実施の形態１の場合と異なる構造のヒートシール部３０，３１により閉じられる。すなわち、これらのヒートシール部３０，３１は、フィルム状包材１５の折り返し部の両端における角部１４に気泡状の非ヒートシール部３２が残るように形成される。   The open edges on the two sides in the direction intersecting the folded portion of the sealing bag 29 are closed by the heat seal portions 30 and 31 having a structure different from that in the first embodiment. That is, these heat seal portions 30 and 31 are formed such that the bubble-like non-heat seal portions 32 remain at the corner portions 14 at both ends of the folded portion of the film-like packaging material 15.

この気泡状の非ヒートシール部３２は例えば四半円形に形成される。この非ヒートシール部３２は、四半円形の他、三角形、四角形等に形成することも可能である。この非ヒートシール部３２は、非ヒートシール部３２に対応したヒートシールバーの一部を切除するなどの方法により形成することができる。   The bubble-shaped non-heat seal portion 32 is formed in, for example, a quarter circle. The non-heat seal portion 32 can be formed in a triangle, a quadrangle, or the like in addition to a quarter circle. The non-heat seal portion 32 can be formed by a method such as excising a part of the heat seal bar corresponding to the non-heat seal portion 32.

このように密封袋２９に設けられた気泡状の非ヒートシール部３２とヒレ状の非ヒートシール部１３とにより、密封袋２９の四つの角部１４から尖端が解消され、その結果密封袋２９の角部１４が使用者の皮膚に当たったとしても使用者に違和感、不快感を与えないことになる。   The bubble-shaped non-heat-sealed portion 32 and the fin-shaped non-heat-sealed portion 13 provided in the sealing bag 29 in this way eliminate the sharp edges from the four corners 14 of the sealing bag 29, and as a result, the sealing bag 29. Even if the corner portion 14 of the contact with the user's skin, the user will not feel uncomfortable or uncomfortable.

この密封袋２９の製造方法について説明すると、実施の形態１と同様にして、フィルム状包材１５を長さ方向に送りながら同方向に平行な線上で折り返しつつ、同方向に伸びる縦ヒートシール部８を設けて筒状の重畳体を形成し、同方向に交差する方向に伸びる図６に示すような横ヒートシール部３３により重畳体を下流側で閉じ、上流側から内容物を重畳体内に充填し、他の横ヒートシール部３３により重畳体を上流側で閉じて上下の横ヒートシール部３３，３３間に内容物を密封し、しかる後重畳体から密封袋２９を横ヒートシール部３３上で切り離すようにする。横ヒートシール部３３は、図５に示した上下の横シール部３０，３１を重畳体の長さ方向に連接した形状及び大きさを有する。図６中、符号３４で示す二点鎖線は、横ヒートシール部３３の中央を通る切り離し線を示し、この切り離し線３４で密封袋２９が切り離されることにより、横ヒートシール部３３が上下の横ヒートシール部３０，３１に分断される。   The manufacturing method of the sealing bag 29 will be described. Like the first embodiment, the film-like packaging material 15 is fed back in the length direction while being folded back on a line parallel to the same direction, and the vertical heat seal portion extending in the same direction. 8 is formed to form a cylindrical superposed body, and the superposed body is closed on the downstream side by a lateral heat seal portion 33 as shown in FIG. 6 extending in the direction intersecting the same direction, and the contents are put into the superposed body from the upstream side. Then, the superposed body is closed on the upstream side by another horizontal heat seal portion 33 to seal the contents between the upper and lower horizontal heat seal portions 33, 33, and then the sealing bag 29 is sealed from the superposed body to the horizontal heat seal portion 33. Try to detach it above. The horizontal heat seal portion 33 has a shape and a size in which the upper and lower horizontal seal portions 30 and 31 shown in FIG. 5 are connected in the length direction of the superposed body. In FIG. 6, a two-dot chain line indicated by a reference numeral 34 indicates a separation line passing through the center of the horizontal heat seal portion 33, and the sealing bag 29 is separated by the separation line 34. The heat seal parts 30 and 31 are divided.

図６に示すように、この製造方法において、縦ヒートシール部８は、実施の形態１の場合と同様に、重畳体の折り返し部と反対側の側縁に幅狭のヒレ状の非ヒートシール部１３が残るように形成するが、実施の形態１の場合とは異なり、横ヒートシール部３３は、折り返し部内の密封袋２９の切り離し線３４下に気泡状の非ヒートシール部３２が残り、かつ折り返し部と反対側の側縁に幅狭の非ヒートシール部１３が残るように形成する。   As shown in FIG. 6, in this manufacturing method, as in the case of the first embodiment, the vertical heat seal portion 8 has a narrow fin-like non-heat seal on the side edge opposite to the folded portion of the superimposed body. However, unlike the case of the first embodiment, the horizontal heat seal portion 33 has a bubble-like non-heat seal portion 32 left below the separation line 34 of the sealing bag 29 in the folded portion, And it forms so that the narrow non-heat-sealing part 13 may remain in the side edge on the opposite side to a folding | returning part.

この製造方法において、内容物Ａは横ヒートシール部３３を形成する都度定量充填することとし、上流側の横ヒートシール部３３を形成する位置は、充填された液体等の表面よりも上側に設定することで非ヒートシール部３２内への内容物Ａの封入を回避することができる。また、内容物がポテトチップスのような固形物である場合も液体の場合と同様に間欠的に充填することで適正に密封袋を作ることができる。   In this manufacturing method, the content A is fixedly filled each time the horizontal heat seal portion 33 is formed, and the position where the upstream side heat seal portion 33 is formed is set above the surface of the filled liquid or the like. By doing so, it is possible to avoid the content A from being enclosed in the non-heat seal portion 32. Moreover, when the content is a solid material such as potato chips, a sealed bag can be appropriately formed by intermittently filling the same as in the case of liquid.

横ヒートシール部３３は、図３及び図４に示したヒートシールローラ２３ａ，２３ｂのヒートシールバー２５を図６に示した横ヒートシール部３３に対応した形状を有するものに付け替えることにより形成することができる。また、図３及び図４に示した左右一対のヒートシール車２０ａ，２０ｂ，２０ｃ，２０ｄのうち、右側の縦ヒートシール部９に対応したものは単なる摩擦車と交換するか、内蔵ヒータへの通電を遮断するか、あるいは重畳体に接しない位置へと移動させることで、重畳体を安定して走行させることができる。   The horizontal heat seal portion 33 is formed by replacing the heat seal bar 25 of the heat seal rollers 23a and 23b shown in FIGS. 3 and 4 with a shape corresponding to the horizontal heat seal portion 33 shown in FIG. be able to. Of the pair of left and right heat seal wheels 20a, 20b, 20c, and 20d shown in FIGS. 3 and 4, the one corresponding to the right vertical heat seal portion 9 can be replaced with a simple friction wheel, or the built-in heater The superimposed body can be stably driven by shutting off the power supply or moving to a position not in contact with the superimposed body.

なお、この実施の形態２において実施の形態１におけるものと同じ部分には同一符号を用いて示すことで重複した説明を省略する。   In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

＜実施の形態３＞
図７に示すように、実施の形態１、２の場合と異なり、この密封袋３５におけるフィルム状包材の重畳体は、対向する二辺に折り返し部を有し、両折り返し部の中間に合掌状に重なり合った開放縁をシールするヒートシール部３６を有する。 <Embodiment 3>
As shown in FIG. 7, unlike the case of the first and second embodiments, the superposition of the film-like packaging material in the sealing bag 35 has folded portions on the two opposing sides, and the palm is located between the folded portions. And a heat seal portion 36 for sealing the open edges that overlap each other.

また、この密封袋３５の折り返し部に交差する方向における二辺の開放縁は、実施の形態１、２の場合と異なる構造のヒートシール部３７，３８により閉じられる。すなわち、これらのヒートシール部３７，３８は、左右の折り返し部の両端における角部１４に気泡状の非ヒートシール部３９が残るように形成される。   Further, the open edges on the two sides in the direction intersecting with the folded portion of the sealing bag 35 are closed by the heat seal portions 37 and 38 having different structures from those in the first and second embodiments. That is, these heat seal portions 37 and 38 are formed such that bubble-like non-heat seal portions 39 remain at the corner portions 14 at both ends of the left and right folded portions.

このように密封袋３５の各隅に設けられた気泡状の非ヒートシール部３９により、密封袋３５の四つの角部１４から尖端が解消され、その結果密封袋３５の角部１４が使用者の皮膚に当たったとしても使用者に違和感、不快感を与えないことになる。   As described above, the bubble-shaped non-heat-sealed portion 39 provided at each corner of the sealing bag 35 eliminates the sharp edges from the four corner portions 14 of the sealing bag 35, and as a result, the corner portion 14 of the sealing bag 35 becomes the user. Even if it touches the skin, it does not give the user a sense of discomfort or discomfort.

この密封袋の製造方法について説明すると、フィルム状包材を長さ方向に送りながら筒状にし、開放縁を合掌状に重ね合わせて縦ヒートシール部３６を形成し、続いて扁平な重畳体にし、図８に示すような上記長さ方向に交差する方向に伸びる横ヒートシール部４０により重畳体を下流側で閉じる。   The manufacturing method of this sealing bag will be described. The film-like packaging material is formed into a cylindrical shape while being sent in the length direction, the open edges are overlapped in a palm shape to form the vertical heat seal portion 36, and then a flat overlapping body is formed. The superposed body is closed on the downstream side by a horizontal heat seal portion 40 extending in a direction intersecting the length direction as shown in FIG.

横ヒートシール部４０は、両側の折り返し部内における密封袋３５の切り離し線３４下に気泡状の非ヒートシール部３９が残るように形成する。   The horizontal heat seal part 40 is formed so that a bubble-like non-heat seal part 39 remains under the separation line 34 of the sealing bag 35 in the folded parts on both sides.

The sterilizing effect of the film-shaped packaging material 15 by the later sterilizing agent is enhanced by the heat of preheating. The preheated film-shaped packaging material 15 is sprayed with a mist of hydrogen peroxide water as a sterilizing agent from the sterilizing agent discharge nozzle 44. This mist is generated by spraying an aqueous solution of hydrogen peroxide, heating it to the boiling point or higher, vaporizing it, and condensing it into fine particles. The bactericidal agent is not limited to hydrogen peroxide, and various chemicals having a bactericidal action can be used. By spraying mist, the surface of the film-like packaging material 15 is sterilized. The surplus mist is recovered from the mist exhaust duct 45. The sterilized film-like packaging material 15 passes through the partition wall 49 and is blown with hot air from the hot air nozzle 46, and the sterilizing agent attached to the surface is vaporized and removed by the heat. The film-like packaging material 15 from which the disinfectant has been removed is blown with cool air from the cool air nozzle 47, thereby promoting the removal of the disinfectant.

殺菌部４１で殺菌されたフィルム状包材１５は、各種ローラ５１を経て次の製袋部４２へと送られ、内容物Ａの包装に供される。   The film-like packaging material 15 sterilized by the sterilization unit 41 is sent to the next bag making unit 42 through various rollers 51 and provided for packaging of the contents A.
