Patent Document 4 discloses a similar method for manufacturing a container. That is, in the method for manufacturing a container disclosed in Patent Document 4, a tube material is formed by bending a sheet material along one axis and bonding along a side edge of the folded and stacked sheet material. The overlapping portions of the tube-shaped body are spread apart from each other, an intermediate portion is defined by an end portion side edge, the intermediate portion forms the end portion side portion, and the end portion side portion is formed.

前記特許文献 1には、前記容器の製造方法 (包装方法）については、単に「包装装 置は、既存の包装機に設置される装置であり得る。この装置は下記の操作を行う。 - 適当な計量分配装置からプラスチックインサートの取り出し; インサートの装填後の 、エンベロープ開口部中へのインサートの配置; 必要により、生産ラインに沿った包 装材の搬送。」（特許文献 1の段落 [0031]欄参照。）と記載されているにすぎず、包 装方法や装置の詳細については記載されていない。また、特許文献 2では、前記抽 出口装置は、「袋の口内に裏と表のフィルム間に挟むようにして挿入され、溝付のヒ 一トシ一ルバ一により裏表から圧着することでリブがフィルム内に喰い込むようにして 溶融すると同時に、リブの先端が、裏と表のフィルム間において溶融する」（特許文献 2の段落 [0012]欄参照。）、「袋内に内容物を充填したのち、ヒートシール肩の部分 を袋の口内に揷入し、ヒートシール法により取り付けられる。」（特許文献 2の段落 [00 06]欄参照。）、「袋内に内容物を充填したのち、あとから注出口を取り付けるようにす ると、内容物の充填を能率的に行うことができると共にリブの作用で確実に融着する ので、仮に多少の挟雑物があってもピンホールが発生したりしなレ、。」（特許文献 2の 段落 [0019]欄参照。）と記載されている。しかし、例えば収容体としてのェンベロー プ (袋）が縦長のほぼ矩形状などの場合には、特許文献 1におレ、てエンベロープ開 口部中へインサートを配置する場合、また特許文献 2において抽出口装置を袋の口 内に裏と表のフィルム間に挟むようにして挿入してヒートシールバーにより袋のフィノレ ム内面に溶着させる場合に、前記インサートや抽出口装置を取り付けるエンベロープ (袋)上端辺の幅が狭くて前記インサートや抽出口装置を挿入する開口部の幅を大き くとれない収容体の場合には、 2枚の熱溶着性フィルムを重ね、または:!枚の熱融着 性フィルムをその長手方向にそって 2つ折りにして、これら重ねたフィルムの両端を熱 シールなどにより接着して予めエンベロープ (袋）を形成した後、前記インサートゃ抽 出口装置を開口内へ揷入、配置しょうとしても、前記フィルムが密接して重なりあって レ、てエンベロープ (袋）の開口部を開口しにくぐ工業的な連続した大量生産に適用 するには生産工程上で問題が発生し易ぐ生産効率が低下するおそれがある。した がって、一般に、前記エンベロープ (袋）の幅に対して、前記インサートや抽出口装置 を取り付けるための開口幅は 50%未満でないと、製造工程の自動化は困難であると されている。また、特許文献 3では、包装容器を構成するフィルム片に開けた穴にフィ ットメントを挿着したのち、フィルム片をフィットメントから離れる方向に半分に折り曲げ るようにしているので、フィットメントの揷着時に穴を広げる必要はないが、フィットメン トを挿着したのちフィルム片を折り曲げ、重ね合わせ、フィルム縁を融着などにより接 着してバウチを閉じる方法は製造工程および装置が複雑となる。さらに、特許文献 4 に開示された容器の製造方法では、前記特許文献 3記載の方法と同様の問題に加 えて、前記チューブ状体の幅が狭い場合には、該チューブ状体の重ねられた部分を 相互に離して広げ、端部側部側縁によって中間部を画定することが困難であるという 、前記特許文献 1、 2と同様の問題がある。 Patent Document 1 discloses a method of manufacturing (packing) the container simply by saying “the packaging device may be a device installed in an existing packaging machine. This device performs the following operation. Removal of the plastic insert from a suitable dispensing device; placement of the insert in the envelope opening after loading of the insert; transport of the packaging material along the production line if necessary. "(Patent Document 1, paragraph [0031] Column), but no details of the packaging method or equipment. Further, in Patent Document 2, the extraction device is described as follows: “The rib is inserted into the mouth of the bag so as to be sandwiched between the back and front films, and is pressed from the front and back by a grooved heat-sealing bar so that the ribs are inserted into the film. The rib ends melt between the back and front films at the same time as it melts into the bag (see paragraph [0012] in Patent Document 2). The shoulder is inserted into the mouth of the bag and attached by heat sealing. "(See paragraph [0006] of Patent Document 2)," After filling the contents of the bag, the spout By attaching a hole, the contents can be efficiently filled and the ribs are reliably fused, so that even if there are some contaminants, pinholes do not occur. (See paragraph [0019] of Patent Document 2). ). However, for example, in the case where the envelope (bag) as the container is vertically long and substantially rectangular, etc., as described in Patent Document 1, the envelope is opened. In the case of placing an insert in the mouth, or in Patent Document 2, inserting the extraction mouth device into the mouth of the bag so as to be sandwiched between the back and front films and welding it to the inner surface of the finolem of the bag with a heat seal bar In the case where the width of the upper end side of the envelope (bag) to which the insert or the outlet device is to be attached is so narrow that the width of the opening for inserting the insert or the outlet device cannot be made large, two sheets of heat welding are required. After the heat-fusible film is folded in two along its longitudinal direction, the ends of these films are bonded together by heat sealing, etc. to form an envelope (bag) in advance. However, even if it is attempted to insert and extract the insert / extraction device into the opening, the films are closely overlapped, and the opening of the envelope (bag) is opened to open. When applied to continuous mass production, problems may occur in the production process and production efficiency may decrease. Therefore, in general, it is considered that automation of the manufacturing process is difficult unless the opening width for attaching the insert or the spout device is less than 50% of the width of the envelope (bag). Further, in Patent Document 3, after a fitment is inserted into a hole formed in a film piece constituting a packaging container, the film piece is bent in half in a direction away from the fitment. It is not necessary to widen the holes when attaching, but the method of bending the film pieces after inserting the fitment, overlapping, bonding the film edges by fusing, etc., and closing the vouch complicates the manufacturing process and equipment. . Furthermore, in the method for manufacturing a container disclosed in Patent Document 4, in addition to the same problems as the method described in Patent Document 3, when the width of the tubular body is narrow, the tubular body is stacked. There is the same problem as in Patent Documents 1 and 2 that it is difficult to spread the portions apart from each other and to define the intermediate portion by the side edges of the end portions.

発明の開示 発明が解決しょうとする課題 Disclosure of the invention Problems the invention is trying to solve
[0005] そこで、熱融着性フィルムからなるチューブ状または袋状の収容体であって、前記 のような縦長の矩形状で、前記のようなインサート、抽出口装置、フィットメントなど（以 下、これら、収容体に充填、密封された流動性を有する物品または材料などを収容 体から押し出し、絞り出しまたは抽出するために、収容体に取着される部材を「スバウ ト」という。）を前記フィルム間に接着した収容体内に、比較的少量の収容物を充填、 密封した製品の場合には、例えば図 18 (a)に示すように、可撓性を有する合成樹脂 フィルムなどからなる矩形状の収容体 (袋体） aにおける長辺側の縁部 bにスパゥト Sを 取着した包装体 Aが提案されてレ、る。  [0005] Therefore, a tube-shaped or bag-shaped container made of a heat-fusible film, which has a vertically-long rectangular shape as described above, and has an insert, an extraction port device, a fitment, etc. A member attached to the container for extruding, squeezing, or extracting a fluid or an article or a material filled and sealed into the container and having fluidity is referred to as a “sbout”. In the case of a product in which a relatively small amount of material is filled and sealed in the container adhered between the films, for example, as shown in Fig. 18 (a), a rectangular shape made of a flexible synthetic resin film is used. A package A in which a spurt S is attached to the edge b on the long side of the container (bag) a has been proposed.
[0006] この包装体 Aは、概略、図 18 (b)— (e)の工程によって製造される。すなわち、例え ば、少なくとも片面が熱可塑性樹脂のような熱融着性 (熱シール性）を有する材料で 構成され、前記収容体 aの表裏を構成する 2枚のフィルム fを、熱融着性を有する面を 内側にして（対面させて）重ねあわせるカ または前記収容体 aの長さ（図 18 (a)にお ける上下方法の長さ）のほぼ 2倍の幅を有する同様のフィルムを前記熱融着性を有 する面が内側になるように半分に折り曲げて重ね合わせ、前記重ねあわせたフィルム f同士の両短辺側の縁部 cを熱シール hして扁平（開口している縁部 bに較べて前記 熱シール hした縁部 cが短レ、）な筒状に形成する（図 18 (b)参照。）。次に、図 18 (c)  [0006] The package A is generally manufactured by the steps shown in FIGS. 18 (b) to 18 (e). That is, for example, at least one surface is made of a material having a heat-sealing property (heat-sealing property) such as a thermoplastic resin, and the two films f forming the front and back of the container a are heat-sealed. Or a similar film having a width almost twice as long as the length of the container a (the length in the vertical direction in Fig. 18 (a)). The film f is folded in half so that the surface having the heat-sealing property is on the inside, and is overlapped, and the edges c on both short sides of the overlapped films f are heat-sealed h to be flat (opened). The edge c that has been heat-sealed h is shorter than the edge b (see FIG. 18 (b)). Next, Fig. 18 (c)

The edge b is heat sealed together with the edge b to seal the edge b, and at the same time, the spat S is adhered to form a bag-shaped container a.

Thereafter, as shown in FIG. 18 (d), a liquid, paste-like, or other fluid material m is filled from the opening (upper end opening) o on the edge b of the container a.

に押すことで容易に開口部が開口し、該開口部にスパゥト Sの接着部 Sを収容体 aの 表裏を構成するフィルム f間に熱シールにより容易に接着することができる。なお、こ こでは収容体 aにおける表裏 2枚のフィルム f間およびフィルム fとスパゥト Sの接着部 S とを熱シールにより接着する場合について説明したが、接着剤により接着される場 合もある。 The opening is easily opened by pressing the adhesive S of the spout S into the opening of the container a. It can be easily adhered by heat sealing between the films f constituting the front and back. Here, the case where the space between the front and back two films f in the container a and between the film f and the bonding portion S of the spurt S are bonded by heat sealing has been described, but they may be bonded by an adhesive.
[0008] 前記のように収容物 mを充填した後に収容体 aを熱シールまたは接着剤で接着して 密封する場合、熱シールの際の熱や接着剤成分が収容物 mに悪影響を与えないよ うにするため、図 18 (e)に示すように収容物 mとの間に空隙 eを残す必要がある。とこ ろ力 前記包装体 Aのように収容物 mを充填した後に、収容体 aにおける長辺側の縁 部 bを接着する場合には、短辺側を接着する場合に較べて接着幅（図 18 (e)におけ る熱シール hの図中水平方向の幅）が大きくなる分、収容体 a内空間容積に占める  [0008] When the container a is sealed with a heat seal or an adhesive after being filled with the container m as described above, heat and adhesive components at the time of heat sealing do not adversely affect the container m. In order to achieve this, it is necessary to leave a gap e between the container and the container m as shown in Fig. 18 (e). Rolling force After the container m is filled as in the case of the package A, when the long side edge b of the container a is bonded, the bonding width (see FIG. 4) is smaller than when the short side is bonded. 18 (e), the width of the heat seal h in the horizontal direction in the figure)

空隙 eの割合が大きくなることから、例えば収容体 aが 10g程度の収容可能な容積を 有する少容量の収容体の場合、収容体 aの収容可能な容積の 50%程度しか収容物 mを充填できず、収容体の容量に対する充填率が極めて低いものしか得られない、 といった問題がある。さらに、図 18 (a)に示すように、矩形状の収容体 aにおける長辺 側の縁部 bにスパゥト Sを取着したものでは、製品外観 (デザイン）上、芳しくないだけ でなぐスパゥト Sの開封作業がし難レ、、さらには、収容体 aから流動性を有する物品 または材料などの収容物 m、例えば歯磨き剤やシャンプーなどを絞り出す場合、スパ ゥト Sより上部の収容空間部分に収容物が残り、収容体 aから収容物 mを完全に絞り 出すことが困難となる、といった問題がある。  Because the proportion of the gap e increases, for example, if the container a is a small-capacity container having a capacity of about 10 g, only about 50% of the capacity of the container a can be filled with the container m. However, there is a problem that only an extremely low filling rate with respect to the capacity of the container can be obtained. Further, as shown in FIG. 18 (a), in the case where the spat S is attached to the long side edge b of the rectangular container a, the spat S which is not only unsatisfactory in terms of product appearance (design) When it is difficult to open the container, or when squeezing out the container m such as a fluid article or material from the container a, for example, dentifrice or shampoo, the container space above the spat S There is a problem that it is difficult to completely squeeze out the container m from the container a because the container remains.
[0009] そこで、本発明は、上記のような、合成樹脂フィルムなどからなる可撓性を有する袋 状またはチューブ状の収容体にスパゥトを取着した包装体における問題点に鑑み、 少量の収容物を充填、収容する比較的小容量の包装体における、スパゥト取付位置 の開口幅が小さくとも容易にスパゥトを取着することができ、外観、使い勝手、および 収容物の充填率の高い包装体を、複雑な工程や包装装置を用いることなく低コスト で製造可能な包装方法、包装装置ならびに包装体を提供せんとするものである。 課題を解決するための手段 [0009] In view of the above, the present invention has been made in view of the above-described problems in a package in which a spat is attached to a flexible bag-like or tube-like container made of a synthetic resin film or the like, and a small amount of the package is provided. In a relatively small-capacity package for filling and storing objects, even if the opening width at the spurt mounting position is small, the spat can be easily attached, and a package with a high appearance, ease of use, and a high filling rate of the contents is provided. Another object of the present invention is to provide a packaging method, a packaging device, and a package that can be manufactured at low cost without using complicated processes and packaging devices.

A pair of web delivery rolls 109, which are substantially vertical and are opposed to each other, change the posture so that the surfaces thereof are substantially vertical, and supply the web W in the axial direction, which constitutes the web polymerization means 102. A pair of web folding rolls that are orthogonal to the direction of the By being supplied between 10, it is folded in two along the longitudinal direction and overlapped to form the front and back of the container 2. The web W has a width approximately perpendicular to the longitudinal direction (the direction in which the web is supplied), and has a width approximately twice that of the container 2. When the web W is folded in half, the web W overlaps to form the front and back of the container 2. Is done. The web W constituting the front and back of the container 2 is formed of a film or a sheet which has at least a folded inner surface which has a heat-sealing property and can be adhered to each other by heat-sealing. You. Such a film or sheet has flexibility for forming the front and back of the container 2 and at least the inner surface is formed of a heat-fusible material, for example, a thermoplastic resin film. For example, a laminate composite film, a co-extruded film and the like are used. The thermoplastic resin of the thermoplastic film includes, for example, a force S including polyethylene (PE), low density polyethylene (LDPE), and the like, but is not limited thereto. In the case where the folded web W is adhered on both sides thereof with an adhesive to form the container 2, the film or sheet is not necessarily required to have a heat-sealing property as long as it has flexibility. You don't have to. Further, when a web having a gas barrier property such as a metal film, for example, an aluminum film laminated or a metal-deposited composite film or sheet is used as the web W, for example, cosmetics, toothpaste, etc. It is suitable as a package for a container containing volatile components such as fragrances. Further, when the surface of the film or sheet as the web W is made of a polyethylene terephthalate resin, a print of a trademark or a product description is printed on the surface of the container 2 where the printability of the surface of the web W is improved. Suitable for application. Also, on the outer surface of the web W, for example, as shown in FIGS. 2 and 4, marks 111 for position detection are printed at regular intervals corresponding to the length of a single container, and The position detection mark 111 is detected at an appropriate position in the bag making process 100 of the apparatus M, supplied from the web supply means 101, and folded into two by the web polymerization means 102 so as to constitute the front and back of the container 2. The web W () is overlapped, heat-sealed on both sides by side sealing means 103 to form a continuous bag-like container 2a, and further cut by the cutting means 104 into a single container 2 web ( And one or more mark sensors 112 for detecting the position of the container 2a) formed continuously therefrom are provided, and the web W (the container 2a formed continuously) at the time of processing in each step is provided.

Although not shown, various types of product information such as product trademarks and product descriptions are printed on the surface (outer surface) of the web W between the position detection marks 110.
[0032] 次に、前記のように、収容体 2の表裏を構成すべく 2つ折り（半分）に折り曲げられた ウェブ Wには、収容体 2の表裏を形成するフィルムまたはシート間に、開口形成手段 105としてマンドレル 106が配置される。このマンドレル 106は、図 1、図 2、図 4に示 すように、連続して収容体 2aを形成すベぐウェブ重合手段 102の折り畳みロール 1 10にて 2つ折りにされて供給されるウェブ Wにおける、収容体 2aの表裏を構成する 上下のフィルムまたはシート間に配置されるとともに、マンドレル 106は、サイドシール 手段 103、さらには単一の収容体 2に小分けする切断手段 104にわたつて設けられ ている。そして、図例の包装装置 Mでは、マンドレノレ 106の基端は、ゥヱブ重合手段 102の折り畳みロール 110とサイドシール手段 103との間に配置されるとともに、該基 端力 側方に、折り畳まれたウェブ Wの開放側の側端縁 119から突出する状態で作 動腕 106cが突設されている。該作動腕 106は、図示しない前後駆動手段（リニアァ クチユエータ）に連結されており、該駆動手段によりマンドレル 106はウェブ W (フィル ムまたはシート）が供給される方向にそって前後動可能に設けられ、図 4に示すように 、その先端 106bは、切断手段 104の前後に進退可能に設けられている。また、この 開口形成手段 105としてのマンドレル 106は、図 2、 4に示すように、その軸方向（ゥ工 ブ重合手段 102から切断手段 104に向力 長手方向）に直交する断面形状が、収容 体 2に取着されるスパゥト Sにおける収容体 2への接着部、例えば、図 13に示すスパ ゥト Sにおける接着部 13のように、中央の抽出口部 11から両側先端部に向力 ほど 肉薄となるような接着部 13の断面形状 (横断面）に近似した大きさ、形状に形成され ている。したがって、収容体 2をスパゥト Sの接着部 13の形状に応じて開口した形状 に癖付けすることができ、スパゥト取着工程 200における、収容体 2の開口部へのス パゥト Sの取り付けが容易になる。  Next, as described above, the web W folded in half (half) to form the front and back of the container 2 has an opening formed between the films or sheets forming the front and back of the container 2. As means 105, a mandrel 106 is arranged. As shown in FIGS. 1, 2, and 4, the mandrel 106 is supplied to the web supplied by being folded into two by the folding roll 110 of the web polymerization means 102 which continuously forms the container 2a. In W, the mandrel 106 is disposed between the upper and lower films or sheets constituting the front and back of the container 2a, and the mandrel 106 is provided across the side sealing means 103 and further, the cutting means 104 for subdividing into the single container 2. It has been. Then, in the packaging apparatus M of the illustrated example, the base end of the mandrel hole 106 is disposed between the folding roll 110 of the web stacking means 102 and the side seal means 103, and is folded to the side of the base force. An operating arm 106c protrudes from the open side edge 119 of the web W. The operating arm 106 is connected to a not-shown front-rear drive means (linear actuator), and the mandrel 106 is provided so as to be able to move back and forth along the direction in which the web W (film or sheet) is supplied by the drive means. As shown in FIG. 4, the distal end 106b is provided so as to be able to advance and retreat before and after the cutting means 104. As shown in FIGS. 2 and 4, the mandrel 106 serving as the opening forming means 105 has a sectional shape perpendicular to the axial direction (the longitudinal direction of the force from the stacking means 102 to the cutting means 104). As shown in FIG. 13, a bonding portion of the spur S attached to the body 2 to the container 2, for example, a bonding portion 13 of the spurt S shown in FIG. It is formed in a size and shape similar to the cross-sectional shape (transverse cross section) of the bonding portion 13 so as to be thin. Therefore, the container 2 can be formed into a shape that is opened in accordance with the shape of the bonding portion 13 of the spart S, and the spurt S can be easily attached to the opening of the container 2 in the spurt attaching process 200. become.
[0033] 製袋工程 100における具体的な工程の詳細を以下に説明する。まず、前記のよう にして折り畳みロール 110にて、収容体 2の表裏を構成するように半分に折り重ねら れたウェブ Wは、サイドシーノレ手段 103により、マンドレル 106の両側で熱シールされ る。このとき、折り重ねられたウェブ Wは、マークセンサ 112により位置検出されて、単 一の収容体 2の長さに応じた長さ毎に移動し、かつ停止するように間欠的にサイドシ ール手段 103に供給される。供給されたウェブ Wは、マンドレル 106の両側に配置さ れた、上下一対（両側で 2対）のヒートシールダイ 114, 115間で熱圧着され、ウェブ Wにおける少なくとも重ね合わせた内面力 S、該内面を構成する熱可塑性材料 (フィル ム）の軟ィ匕点以上の温度まで、一般的には、 140°C 220°Cになるまで加熱されて（ 1秒程度）、収容体 2の表裏を構成するフィルムまたはシートの内面同士力 S、その長 手方向の両側で接着されて連続して収容体 2aが形成される。 （図 2 (b)参照。）。この ようにして両側が接着 (熱シール）されて連続して形成された収容体 2aは、ヒートシ一 ルダイ 114， 115の下流側（後工程側）に、同じくマンドレル 106の両側に配置された 、上下一対（両側で 2対）の冷却ダイ 116, 117間に圧着させることにより前記ヒートシ ールした部分が冷却され、接着される。 [0033] Details of specific steps in the bag making process 100 will be described below. First, as described above, the web W folded in half by the folding roll 110 so as to constitute the front and back of the container 2 is heat-sealed on both sides of the mandrel 106 by the side see-through means 103. The At this time, the position of the folded web W is detected by the mark sensor 112, the web W is moved by a length corresponding to the length of the single container 2, and the side seal is intermittently stopped so as to stop. It is provided to means 103. The supplied web W is thermocompression-bonded between a pair of upper and lower (two pairs on both sides) heat sealing dies 114 and 115 disposed on both sides of the mandrel 106, and at least the superposed inner surface force S of the web W, The inside of the container 2 is heated up to a temperature above the softening point of the thermoplastic material (film) constituting the inner surface, generally to 140 ° C. to 220 ° C. (about 1 second). The force S between the inner surfaces of the constituent films or sheets is adhered on both sides in the longitudinal direction to form the container 2a continuously. (See Figure 2 (b).) The container 2a continuously formed by bonding (heat sealing) on both sides in this manner is disposed on the downstream side (post-process side) of the heat seal dies 114 and 115 and also on both sides of the mandrel 106. The heat-sealed portion is cooled and bonded by pressure bonding between a pair of upper and lower (two pairs on both sides) cooling dies 116, 117.
[0034] 製袋工程 100においては、前記のようにウェブ Wのフィルムまたはシートの両側を 接着して連続して収容体 2aを形成した後、切断手段 104により単一の収容体 2に小 分けする前に、重ね合わせたフィルムまたはシートの側端縁、図例の如ぐウェブ W を 2つ折りに重ねた場合には、図 2 (c)に示すように、折り重ねたウェブ W (連続した収 納体 2a)における折り目 118と反対側の側端縁 119を該フィルムまたはシートの長手 方向にそって切除するトリミング工程を備えることが好ましい。このトリミング工程は、ゥ エブ重合手段 102やサイドシール手段 103において、折り畳んだウェブ Wの側端同 士（開放側の側端縁）が必ずしも完全に一致しない場合があることから、該端部の形 状を整えるために行うものである。なお、 2つのロールから供給される 2枚のフィルムま たはシートを重ね合わせて収容体 2の表裏を構成する場合には、収容体 2における 両側端部について、前記トリミングを施すことが好ましい。  [0034] In the bag making process 100, the container 2a is continuously formed by bonding both sides of the film or sheet of the web W as described above, and then divided into the single container 2 by the cutting means 104. If the web W is folded in two before the side edge of the superimposed film or sheet, as shown in the figure, the folded web W (continuous It is preferable to provide a trimming step of cutting the side edge 119 of the storage body 2a) opposite to the fold line 118 along the longitudinal direction of the film or sheet. In this trimming step, the side edges (open side edges) of the folded web W may not always completely coincide with each other in the EB polymerization means 102 and the side sealing means 103. This is done to adjust the shape. In the case where two films or sheets supplied from two rolls are overlapped to form the front and back of the container 2, it is preferable to perform the trimming on both side ends of the container 2.
[0035] さらに、製袋工程 100においては、図 1に示すように、サイドシール手段 103と切断 手段 104との間、さらに前記のようにサイドシール手段 103の後（下流側）にトリミング 工程を設けたものでは、該トリミングの後に、サイドシール手段 103により両側を接着 して連続して形成され、さらに側端部をトリミングされた収納体 2aを、切断手段 104で 単一の収容体に小分けする前に、製造される単一の包装体 1における収容体 2の形 状に応じてその両側を切断するサイドカット手段 120を設けてある。このサイドカット 手段 120は、例えば、図 8— 12および図 17 (a)に示すようなほぼ矩形状の収容体 2 を有する包装体 1の場合に、収容体 2の四隅に R部を形成すベぐ図 2 (d)、図 3 (a) に示すように切り込み 121を入れたり、さらに図 17 (b) （1)に示すように、収容体 2 における両側部（図 17の各図における収容体 2の左右両側）を各種の形状に形成す る場合にも、このサイドカット手段 120により、連続して形成されている収容体 2aに対 し、その長手方向にそった両側部をカットして所望の形状の収容体 2を得るものであ る。なお、この場合、サイドシール手段 103による両側部のヒートシール部 hも前記サ イドカット形状に応じた形状に熱シールされることは勿論である。また、接着剤により 接着する場合の接着部の形状も同様である。 Further, in the bag making process 100, as shown in FIG. 1, a trimming process is performed between the side sealing means 103 and the cutting means 104 and further after the side sealing means 103 (downstream side) as described above. After the trimming, the storage body 2a formed continuously by bonding both sides by the side seal means 103 and further trimmed at the side end is divided into a single storage body by the cutting means 104 after the trimming. The shape of the container 2 in a single package 1 to be manufactured Side cutting means 120 for cutting both sides according to the shape is provided. For example, in the case of a package 1 having a substantially rectangular container 2 as shown in FIGS. 8-12 and 17 (a), the side cut means 120 forms R portions at four corners of the container 2. As shown in Fig. 2 (d) and Fig. 3 (a), a cut 121 is made, and as shown in Fig. 17 (b) (1), both sides of the container 2 (Fig. Even when the container 2 is formed into various shapes on both the left and right sides, the side cut means 120 cuts both sides along the longitudinal direction of the container 2a formed continuously. Thus, the container 2 having a desired shape is obtained. In this case, it is a matter of course that the heat seal portions h on both sides by the side seal means 103 are heat-sealed in a shape corresponding to the side cut shape. The same applies to the shape of the bonding portion when bonding with an adhesive.

[0045] 上記のように、本発明では、製袋工程 100で、収容体 2の表裏を構成するフィルム、 シートからなるウェブ Wを 2つ折りに重ね合わせ、それらフィルム、シート間に開口形 成用のマンドレル 106を内装してウェブ Wが筒状に開口した状態で両側を接着して 筒状収容体 2aを連続して形成し、該筒状収容体 2の開口状態を維持したまま切断手 段 104で単一の収容体 2に小分けし、さらに移送装置 500および移送コンベア 510 により前記開口状態を維持したままスパゥト取着工程 200へ移送して収容体 2の下端 開口部ヘスパゥト Sを取着した後、充填'密封工程 300の充填装置 301で収容体 2の 上端開口部から流動性収容物を充填し、密封装置 302で収容体 2の上端開口部を 密封して包装体 1を得る。このように、本発明の包装方法および包装装置によれば、 ウェブ Wを、その長手方向にそって折り曲げて収容体 2を形成する製袋工程の当初 から、収容体 2の表裏を構成するフィルムまたはシート間に開口形成手段 105として のマンドレル 106を内装し、筒状に開口した状態で連続して収容体 2を形成すると同 時に、この開口した形態を維持したままスパゥト取着装置 201に送って該収容体 2の 開口部ヘスパゥト Sの接着部 13を挿入し、接着するようにしたことから、前記スパゥト S を挿入、接着するための開口幅を十分広く確保できない比較的小容量の包装体で あっても、スパゥト Sを簡単に取着し、かつ収容体 2を確実に密封することができる。し たがって、上記のような包装方法または包装装置により製造される、可撓性を有する フィルムまたはシートからなりスパゥト Sを備えた収容体 2に流動性を有する収容物が 充填された本発明の包装体 1は、収容体 2の外周形状におけるスパゥト Sが取着され る辺の長さ（図 12中、 Dで示す長さ）に対する、スパゥト Sが取着される収容体 2の開 口幅（図 12中、 dで示す長さ）を 50%以上とすることができる。また、収容体 2の外周 形状におけるスパゥト Sが取着される辺の長さ Dを 50mm以下とすることもできる。さら に、収容体 2の外周形状におけるスパゥト Sが取着される辺の長さ Dと、スパゥト Sが取 着された辺に直交する方向の収容体の長さ（図 12中、 Lで示す長さ）との比（DZL) を 2/5以下とすることができる。また、収容体 2におけるスパゥト Sを取着してなる開口 幅 dを 50mm以下とすることもできる。図 8—図 11に示す実施の形態の包装体 1にお いては、スパゥト Sが取着される辺の長さ Dは 30mm、両側のシール hの幅は各 3mm であり、スパゥト Sが取着される収容体 2の開口幅 dは 24mmである。したがって、スパ ゥト Sが取着される辺の長さ Dに対する開口幅 dの比率は 80%である。なお、スパゥト Sの接着部 13の周壁部 19の全外周は約 41mmであり、周壁部 19の片面の外周長 さは約 20. 5mmであるから、前記辺の長さ Dに対して、約 68%の長さのものを挿入、 接着することになるが、本発明に係る包装方法および包装装置によれば、このように 収容体 2におけるスパゥト Sを取り付ける辺の長さ Dが短ぐしたがってスパゥト Sを挿 着するための開口幅 dが小さくとも容易にスパゥト Sを取着することができる。さらにス パゥト Sが取着された辺に直交する方向の収容体の長さ（図 12中、 Lで示す長さ）は 8 5mmであり、スパゥト Sが取着された辺の長さ Dと、スパゥト Sが取着された辺に直交 する方向の収容体の長さ Lとの比（D/L)は 2/5以下（30Z85 = 6Z17)である。こ のように、本発明によれば、外観、使い勝手、および収容物の充填率の高い包装体 1 を、複雑な工程や包装装置を用いることなく低コストで提供することができる。 As described above, in the present invention, in the bag making process 100, the web W composed of the film and the sheet constituting the front and back of the container 2 is folded in two, and an opening is formed between the film and the sheet. In a state where the web W is opened in a cylindrical shape and the web W is opened in a cylindrical shape, the both sides are adhered to each other to continuously form the cylindrical container 2a, and the cutting method is performed while maintaining the open state of the cylindrical container 2. At 104, the container was subdivided into a single container 2, and further transferred to the spart attaching process 200 while maintaining the above-mentioned open state by the transfer device 500 and the transfer conveyor 510, and the spurt S was attached to the opening at the lower end of the container 2. Thereafter, the filling material 301 in the filling / sealing step 300 is used to fill the liquid container from the upper end opening of the container 2, and the upper end opening of the container 2 is sealed with the sealing device 302 to obtain the package 1. As described above, according to the packaging method and the packaging device of the present invention, from the beginning of the bag making process of forming the container 2 by bending the web W along the longitudinal direction, the film forming the front and back of the container 2 Alternatively, a mandrel 106 as an opening forming means 105 is provided between the sheets, and the container 2 is formed continuously in a state of being opened in a cylindrical shape. At this time, while maintaining this open state, the spout S is inserted into the spout attaching device 201 to be inserted into and adhered to the opening of the container 2 by inserting the spur S, so that the spurt S is inserted and adhered. Even in the case of a relatively small-capacity package that cannot secure a sufficiently large opening width, the spat S can be easily attached and the container 2 can be securely sealed. Therefore, according to the present invention, a container 2 made of a flexible film or sheet and provided with a spurt S, which is manufactured by the above-described packaging method or packaging apparatus, is filled with a container having fluidity. The package 1 has an opening width of the container 2 to which the spurt S is attached, with respect to the length of the side of the outer shape of the container 2 to which the spurt S is attached (length indicated by D in FIG. 12).

Further, the opening width d of the container 2 to which the spat S is attached can be set to 50 mm or less. In the package 1 of the embodiment shown in FIG. 8 to FIG. 11, the length D of the side to which the spat S is attached is 30 mm, the width of the seals h on both sides is 3 mm, and the spat S is The opening width d of the container 2 to be attached is 24 mm. Therefore, the ratio of the opening width d to the length D of the side to which the spat S is attached is 80%. The entire outer circumference of the peripheral wall 19 of the bonding portion 13 of the spur S is about 41 mm, and the outer peripheral length of one side of the peripheral wall 19 is about 20.5 mm. 68% of the length is inserted and adhered, but according to the packaging method and the packaging apparatus according to the present invention, the length D of the side of the container 2 to which the spat S is attached is short. Even if the opening width d for inserting the spur S is small, the spur S can be easily mounted. Furthermore, the length of the container in the direction perpendicular to the side where the spur S is attached (the length indicated by L in FIG. 12) is 85 mm, and the length D of the side where the spur S is attached is However, the ratio (D / L) to the length L of the container in the direction orthogonal to the side where the spurs S are attached is 2/5 or less (30Z85 = 6Z17). As described above, according to the present invention, it is possible to provide a package 1 having a high appearance, ease of use, and a high filling rate of contents at a low cost without using a complicated process or a packaging device.
