  The present invention relates to a packaging method, a packaging apparatus, and a packaging body, and a container having fluidity, for example, a container such as a liquid, paste, gel, sol article or material, or a tube-shaped or bag-shaped packaging container. A package containing a small amount of about 2 to several tens of grams in (container) and sealed, for example, a toothpaste, shampoo, rinse, etc. provided in a guest room of an accommodation facility such as a hotel. In addition, the present invention relates to a packaging method and a packaging apparatus for a package that is filled and sealed in a tube-shaped container, and more particularly to a flexible film or sheet that can be heat-sealed. The present invention relates to a packaging method, a packaging apparatus, and a packaging body for producing a packaging body in which an extraction port member is integrally attached to an opening of a filled and sealed container.

  Conventionally, as a container for filling and sealing a container having fluidity as described above into a tube-shaped or bag-shaped container, a heat-sealable, substantially flexible laminate or coextruded film is used. A container for a limited dose of liquid, oil, cream, in particular an envelope, a bag, etc., having a container body formed by a composite film comprising a neck, having a base, holes, welded to the head part of the envelope A cap with a limited break and a knurled pin protruding from the center of the cap that is re-inserted into the base after the cap has been broken and tilted 180 ° to ensure sealing of the envelope A resealable container having a substantially rigid insert has been proposed (see, for example, Patent Document 1). Furthermore, as an extraction port device which is a re-sealable insert (extraction port member) provided in the opening of the head portion of the envelope (bag) and which can be resealed by dividing the integrally formed cap, A cap for closing the spout is integrally formed at the upper end in an inverted state, and a long heat-sealing shoulder is formed integrally at the lower end of the spout so that the tip of the heat-sealing shoulder becomes gradually thinner. There has been proposed a bag spout device that is devised so that pinholes do not occur at the portion where the tip of the heat-seal shoulder and the film on the back and front of the bag are combined. Further, as a resealable pouch packaging container, a) a substantially rigid fitment (member similar to the insert and the extraction port device), the fitment includes an inner end, an outer end, An orifice extending from the inner end to the outer end, and a flat flange at the inner end, b) a hole is provided in the thermoplastic film piece constituting the packaging container, and the hole in the film piece A recess is formed by molding means, the flat flange of the fitment is bonded to the hole portion of the film piece, and the film piece is bent in a direction away from the fitment and overlapped with the bent end. A laminated film edge is formed, the overlapping film edges are glued together, and the pouch is closed except for the orifice portion of the fitment. A reclosable pouch packaging container in which the concave portion of the film piece is configured to receive the flat flange of the fitment, and a manufacturing method of the pouch packaging container, a) by molding means Forming a recess in the thermoplastic film piece; b) a hole for flowing fluid between the substantially rigid fitment having a planar flange and an orifice therethrough; and a pouch; From the fitment so as to form a step of opening the recess, c) adhering a flat flange of the fitment to the recess of the film piece, and d) forming an edge of the folded end and an overlapping film edge. A step of bending the film piece in the direction of leaving, and e) adhering the overlapping film edges to each other, A container manufacturing method has also been proposed, which includes a step of closing the pouch except for a portion of the film piece and forming a recess of the film piece into a shape suitable for mounting a flat flange of the fitment (for example, (See Patent Document 3). Patent Document 4 also discloses a similar container manufacturing method. That is, in the container manufacturing method disclosed in Patent Document 4, a sheet material is bent along one axis, and bonded along side edges of the sheet material that are folded and stacked to form a tubular body. , The overlapping portions of the tubular body are spread apart from each other, an intermediate portion is defined by an end portion side edge, and the end surface side portion is formed by the intermediate portion. The lid body is attached, and the paste-like product is filled into the expanded tubular body through the opening located on the side opposite to the end face side, and the opening is filled with the product. In a method of manufacturing a container that is to be closed later, an outlet opening is formed in the intermediate portion that will form the end face side, and the two overlapping portions of the material are along their side edges. Are welded together, In a state in which the state body is expanded, the fixed connection piece is introduced into the tubular body through the opening located on the side opposite to the end face side portion, and the neck portion of the fixed connection piece is Pushed outward through the outlet opening and secured to the inside of the intermediate portion, and then the lid body constituting the outlet connection piece and the top of the lid is placed on the neck portion of the fixed connection piece protruding from the tubular body. The intermediate portion is fixed between the fixed connection piece and the outlet connection piece, and the paste-like product is filled into the tubular body through the opening. A method for producing a deformable container, characterized in that the opening is closed and welded.

  In Patent Document 1, the manufacturing method (packaging method) of the container is simply “the packaging device may be a device installed in an existing packaging machine. This device performs the following operations. Removal of the plastic insert from the dispensing device;-Placement of the insert into the envelope opening after loading of the insert;-Transport of the packaging material along the production line, if necessary. "(Patent Document 1, paragraph [0031] (Refer to the column).) And details of the packaging method and apparatus are not described. Further, in Patent Document 2, the extraction port device is “inserted into the mouth of the bag so as to be sandwiched between the back and front films, and the ribs bite into the film by crimping from the back and front with a grooved heat seal bar. At the same time, the tip of the rib melts between the back and front films ”(see paragraph [0012] of Patent Document 2),“ After filling the contents in the bag, the heat seal shoulder part Is inserted into the mouth of the bag and attached by the heat seal method ”(see paragraph [0006] of Patent Document 2),“ After filling the bag with the contents, the spout is attached later. In addition, the contents can be efficiently filled, and reliably fused by the action of the ribs, so that no pinholes are generated even if there are some interstitial materials ”(paragraph of Patent Document 2). [ 019] are column reference.) And described. However, for example, in the case where the envelope (bag) as the container is vertically long and substantially rectangular, in Patent Document 1, when the insert is disposed in the envelope opening, or in Patent Document 2, the extraction port device is placed in the mouth of the bag. When the insert is inserted between the back and front films and welded to the inner surface of the bag film with a heat seal bar, the width of the upper edge of the envelope (bag) to which the insert or extraction port device is attached is narrow and the insert or extraction In the case of a container in which the width of the opening into which the mouth device is inserted cannot be increased, two heat-weldable films are stacked, or one heat-weldable film is folded in two along its longitudinal direction. Then, both ends of these stacked films are bonded together by heat sealing or the like to form an envelope (bag) in advance, and then the insert and the extraction port device are put into the opening. Even if it is going to be placed and placed, the films are closely overlapped, making it difficult to open the opening of the envelope (bag), and problems are likely to occur in the production process for industrial continuous mass production. , Production efficiency may be reduced. Therefore, in general, it is said that it is difficult to automate the manufacturing process unless the opening width for attaching the insert or the extraction port device is less than 50% with respect to the width of the envelope (bag). Further, in Patent Document 3, the fitment is inserted into the hole formed in the film piece constituting the packaging container, and then the film piece is folded in half in the direction away from the fitment. Sometimes it is not necessary to widen the hole, but the method of folding the film pieces after inserting the fitment, folding them together, and bonding the film edges by fusing etc. to close the pouch makes the manufacturing process and apparatus complicated. Furthermore, in the container manufacturing method disclosed in Patent Document 4, in addition to the same problem as the method described in Patent Document 3, when the width of the tube-shaped body is narrow, the tube-shaped body is overlapped. 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 edge of the end portion side portion.

JP-A-5-162756 (Claim 1, FIG. 1, FIG. 2) Japanese Patent Laid-Open No. 5-229566 (Claim 1, paragraphs [0012] and [0018], FIGS. 1 to 4) Japanese translation of PCT publication No. 10-510790 (Claims 1st, 7th, FIGS. 6-9, 11 and 12) JP-T-2001-514602 (Claim 7 Claims, FIGS. 1-3, FIGS. 11-13)

  Therefore, it is a tube-shaped or bag-shaped container made of a heat-fusible film, and has a vertically long rectangular shape as described above, such as the insert, the extraction port device, the fitment, etc. In order to extrude and squeeze or extract articles or materials having fluidity filled and sealed in the body from the container, a member attached to the container is referred to as “spout”). In the case of a product in which a relatively small amount of contents is filled and sealed in the container, for example, as shown in FIG. 18 (a), a rectangular container (bag) made of a synthetic resin film having flexibility. A package A having a spout S attached to an edge b on the long side of the body a is proposed.

This package A is roughly manufactured by the steps shown in FIGS. That is, for example, at least one surface is made of a material having a heat fusion property (heat sealing property) such as a thermoplastic resin, and two films f constituting the front and back of the container a are made to have heat fusion properties. A similar film having a width approximately twice the length of the container a (the length of the up-and-down method in FIG. Folded in half so that the fusing surface is inside, the edges c on both short sides of the overlapped films f are heat sealed h ₁ and flat (opened edges) Compared to b, the heat-sealed h ₁ edge c is shorter) (see FIG. 18B). Next, as shown in FIG. 18C, a spout S is disposed in one opening (lower end opening) of the long side edges b and b to constitute the front and back of the container a. A heat seal h ₂ is sealed between the two films f together with the edge b to seal the edge b, and at the same time, the spout S is bonded to form a bag-shaped container a. After that, as shown in FIG. 18 (d), the container m is filled with liquid, paste-like or other fluid containing matter m from the opening (upper end opening) o on the edge b side of the containing body a. as shown in FIG. 18 (e), the edge b heat sealing h ₃ to seal the container a to close the opening o, to obtain a package a.

In the case of the package A shown in FIG. 18 as described above, since the spout S can have a wide opening for attaching it, the container a formed in a cylindrical shape is heat sealed h _1. The opening c is easily opened by gripping the edges c on both sides of the heat seal h ₁ with a chuck or the like and pushing it in the direction (inner side) close to each other, and the spout S bonding portion S ₁ is opened in the opening. Can be easily bonded by heat sealing between the films f constituting the front and back of the container a. Here, a case has been described in which an adhesive portion S ₁ between the front and back films f of container a and the film f and spouts S are bonded by heat sealing may also be bonded by an adhesive.

When the container a is adhered and sealed with a heat seal or an adhesive after filling the container m as described above, the heat and adhesive components during the heat sealing do not adversely affect the container m. Therefore, as shown in FIG. 18 (e), it is necessary to leave a gap e between the accommodation m. However, after filling the container m like the package A, when bonding the edge b on the long side of the container a, the bonding width (see FIG. 18) compared to bonding the short side. drawing horizontal width of the heat seal h ₃ in (e)) is increased correspondingly, because the percentage of void e occupying the container a space volume increases, for example, container a is capable of accommodating about 10g In the case of a small-capacity container having a capacity, only about 50% of the capacity that can be accommodated in the container a can be filled with the contents m, and only a very low filling rate with respect to the capacity of the container can be obtained. There is. Furthermore, as shown in FIG. 18 (a), the spout S attached to the edge b on the long side of the rectangular container a is not good in terms of product appearance (design). When the opening of S is difficult to carry out, and the container m such as a dentifrice or shampoo is squeezed out from the container a, such as a dentifrice or shampoo, the container is contained in the storage space above the spout S. There remains a problem that it is difficult to completely squeeze the contained material m from the containing body a.

  Accordingly, the present invention is filled with a small amount of the contents in view of the problems in the packaging body in which the spout is attached to the flexible bag-shaped or tube-shaped container made of a synthetic resin film as described above. The spout can be attached easily even if the opening width of the spout attachment position is small in the relatively small-capacity package to be accommodated, and the package having a high appearance, ease of use, and high filling rate of the contents It is intended to provide a packaging method, a packaging device, and a package that can be manufactured at low cost without using a process or a packaging device.

Although not shown, various 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.

  Next, as described above, the web W folded in half (half) so as to constitute the front and back of the container 2 is formed as an opening forming means 105 between the films or sheets forming the front and back of the container 2. A mandrel 106 is disposed. 1, 2, and 4, the mandrel 106 is formed in a web W that is supplied by being folded in two by a folding roll 110 of the web superimposing means 102 so as to continuously form a container 2 a. The mandrel 106 is provided over the side sealing means 103 and the cutting means 104 which is subdivided into a single container 2, between the upper and lower films or sheets constituting the front and back of the container 2 a. In the illustrated packaging apparatus M, the base end of the mandrel 106 is disposed between the folding roll 110 of the web polymerization means 102 and the side seal means 103 and is folded sideways from the base end. The operating arm 106c is projected from the side edge 119 on the open side of the web W. The operating arm 106 is connected to a front / rear drive means (linear actuator) (not shown), and the mandrel 106 is provided by the drive means so as to be movable back and forth along the direction in which the web W (film or sheet) is supplied. As shown in FIG. 4, the tip 106 b is provided so as to be able to advance and retreat before and after the cutting means 104. Further, as shown in FIGS. 2 and 4, the mandrel 106 as the opening forming means 105 has a cross-sectional shape orthogonal to the axial direction (longitudinal direction from the web polymerization means 102 to the cutting means 104) in the container 2. Bonding part to the container 2 in the spout S to be attached, such as bonding part 13 in the spout S shown in FIG. It is formed in a size and shape that approximates the cross-sectional shape (transverse section) of the portion 13. Therefore, the container 2 can be brazed into a shape opened according to the shape of the bonding portion 13 of the spout S, and the spout S can be easily attached to the opening of the container 2 in the spout attachment process 200. Become.

  The detail of the specific process in the bag making process 100 is demonstrated below. First, the web W folded in half so as to constitute the front and back of the container 2 by the folding roll 110 as described above is heat-sealed on both sides of the mandrel 106 by the side sealing means 103. At this time, the position of the folded web W is detected by the mark sensor 112, and moves side by side according to the length of the single container 2, and the side seal means is intermittently stopped. 103. The supplied web W is thermocompression bonded between a pair of upper and lower (two pairs on both sides) heat seal dies 114 and 115 disposed on both sides of the mandrel 106, and at least the inner surface overlapped on the web W is attached to the inner surface. The film or sheet constituting the front and back of the container 2 is heated to a temperature equal to or higher than the softening point of the thermoplastic material (film) to be formed, generally 140 ° C. to 220 ° C. (about 1 second). The inner surfaces are bonded to each other in the longitudinal direction to continuously form the container 2a. (See FIG. 2 (b)). The container 2a continuously formed by bonding (heat sealing) on both sides in this way is disposed on both sides of the mandrel 106 on the downstream side (post-process side) of the heat sealing dies 114 and 115, The heat-sealed portion is cooled and bonded by pressing between a pair of upper and lower (two pairs on both sides) cooling dies 116 and 117.

  In the bag making process 100, after forming the container 2a continuously by bonding both sides of the film or sheet of the web W as described above, before subdividing into a single container 2 by the cutting means 104, When the web W is folded in two as shown in the side edge of the overlapped film or sheet, as shown in the figure, the folded web W (continuous storage body 2a) as shown in FIG. It is preferable to provide a trimming step of cutting a side edge 119 opposite to the fold 118 in 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 web overlapping means 102 and the side seal means 103. This is what we do to arrange. 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.

  Further, in the bag making process 100, as shown in FIG. 1, a trimming process is provided between the side seal means 103 and the cutting means 104 and further after the side seal means 103 (downstream side) as described above. Then, before the trimming, the storage body 2a continuously formed by adhering both sides by the side seal means 103 and further trimmed at the side end is subdivided into a single storage body by the cutting means 104. The side cut means 120 which cuts the both sides according to the shape of the container 2 in the single package 1 manufactured is provided. For example, in the case of the packaging body 1 having the substantially rectangular container 2 as shown in FIGS. 8 to 12 and FIG. 17A, the side cut means 120 forms R portions at the four corners of the container 2. Therefore, as shown in FIGS. 2 (d) and 3 (a), a notch 121 is made, and as shown in FIGS. 17 (b) to (l), both side portions of the container 2 (each figure in FIG. 17). Even when the right and left sides of the container 2 are formed in various shapes, the side cut means 120 cuts both sides along the longitudinal direction of the continuously formed container 2a. Thus, the container 2 having a desired shape is obtained. In this case, it goes without saying that the heat seal portions h on both sides by the side seal means 103 are also heat sealed to a shape corresponding to the side cut shape. The same applies to the shape of the bonded portion when bonded by an adhesive.

  Next, the container 2a continuously formed as described above is cut by the cutting means 104 and subdivided into a single container 2. In other words, the continuously formed cylindrical container 2a is cut into a single container 2 by being cut into a shape and size corresponding to the package 1 to be manufactured by the cutting means 104. As shown in FIG. 4B, the cutting means 104 is composed of a pair of blade means including a cutting blade 122 and a receiving blade 123 that receives the cutting blade 122. And the cutting | disconnection means 104 cut | disconnects the continuously formed container 2a into the single container 2 as shown to FIG. 1, FIG. 4 (a)-(c), and the opening formation means 105 The mandrel 106 is held by the mandrel 106 at the front (downstream) of the cutting blade 122 of the cutting means 104 together with the cylindrical container 2a continuously formed as described above. The tip of the container 2a protrudes from the blade means 122 by the length of the single container 2, and the container holding means 501 provided in the transfer device 500 is positioned at the tip of the container 2a. After one container 2 is held, the tip 10b of the mandrel 106 is retracted backward from the position of the cutting blade 122 of the cutting means 104 (see FIG. 4B). Between the container holding means 501 b and the transfer device 500 (the tip of), is cut by the cutting means 104 (see FIG. 3 (b).). Thereafter, the mandrel 106 moves forward again, and as shown in FIG. 4C, the tip 106b is guided forward from the cutting blade 122 of the cutting means 104 while holding the continuous container 2a (FIG. c), and a cylindrical shape formed continuously by repeating the operation of holding the container 2 positioned at the tip of the container 2a on the container holding means 501 of the transfer device 500 and then moving back. The container 2a is cut and subdivided into a single container 2.

  After being subdivided into a single container 2 by the cutting means 104 as described above, the subdivided container 2 is subjected to a spout attachment process which is a subsequent process by a transfer device 500 and a transfer conveyor 510 as transfer means. 200. As shown in FIG. 5, the transfer device 500 shown in FIG. 5 has a plurality of rod-like container holding means 501 (from the rotation center shown in FIG. There are 10). This transfer device 500 is held by the container holding means 501 at the time of cutting by the cutting means 104, and a single container 2 obtained by cutting the continuous container 2a is formed into a cylindrical shape by the container holding means 501. While maintaining the opened state, it is transferred to the spout attachment device 201 which is a subsequent process through the transfer conveyor 510. As shown in FIG. 5, the transfer device 500 changes the posture of the container 2 so as to rotate 90 ° around the axis together with the container holding means 501 as the substrate 502 rotates, and sends the container 2 to the transfer conveyor 510. . At this time, in the transfer device 500 shown in the figure, as shown in FIGS. 1 and 5, the container holding means 501 provided around the base body 502 at the transfer position to the transfer conveyor 510 (the uppermost part in the drawing). Are arranged in parallel with each other, and two of the single container 2 are simultaneously transferred to the transfer conveyor 510. In addition, the container holding means 501 has a cross-sectional shape orthogonal to the axial direction that is circular, elliptical, or similar to the cross-sectional shape of the adhesive portion 13 of the spout S, similar to the mandrel 106 as the opening forming means 105 in the bag making process 100. It is formed in a shape, and the container 2 can be transported with the spout S being opened in a shape that facilitates insertion of the adhesive portion 13. The container 2 is transferred from the transfer device 500 to the transfer conveyor 510 by gripping both sides of the two aligned containers 2 with gripping means such as a chuck 503 and pulling them upward from the container holding means 501. The container 2 is configured to be inserted into a container holding bar 512 provided on the conveyor 510 and to hold the container 2 with a clip 513 provided on the container holding bar 512. In the transfer conveyor 510, a large number of moving base units 511 provided so as to be movable from the transfer device 500 toward the spout attachment device 201 are provided with holding body holding bars and clips 513. The container 2 is transferred from the transfer device 500 to the spout attachment device 201.

  The spout attachment device 201 of the spout attachment process 200 inserts and arranges the spout S into the lower end opening of the single container 2 transferred from the bag making process 100 via the transfer device 500 and the transfer conveyor 510. Is bonded to the container 2. The spout attachment device 201 includes a plurality of chucks 202 as a holding body holding means that holds both sides of the holding body 2 transferred from the transfer conveyor 510 and moves together with the moving base unit 511 of the transfer conveyor 510, and a holding body. 2 and a parts feeder 204 for supplying the spout S to be attached to the housing 2. The spout S is inserted into the lower end opening of the housing 2 from below the housing 2 and the spout S inserted into the housing 2 is housed. A spout insertion and temporary fixing device 205 for temporarily fixing the two openings, a main sealing device 207 for adhering the spout S to the container 2 by heat sealing to seal the lower end opening of the container 2, and the sealing device And a cooling device 208 that cools the heat seal portion at the lower end opening by 207. The container 2 is held by the container holding bar 512 and the clip 513 of the transfer conveyor 510 and is transferred to the spout insertion position by the transfer conveyor 510 with both sides being held by the chuck 202. Here, the spout insertion / temporary fixing device 205 inserts the adhesive portion 13 of the spout S from the lower end opening (see FIG. 6B). The spout S is inserted into the container 2 simultaneously with respect to a plurality (two in the illustrated example) of the containers 2 transferred by the transfer conveyor 510. Further, as shown in FIG. 6 (c), the container 2 with the spout S inserted as described above is connected to the spout S bonded portion by the pin-shaped heat seal die 209 of the spout insertion and temporary fixing device 205. Both side positions of 13 are heat-sealed in a dot shape and temporarily fixed. The position of the point seal for temporary fixing is not particularly limited as long as the spout S can be reliably positioned with respect to the container 2. The step of temporarily fixing the spout S by the point seal may be omitted. However, in order to securely close the opening by adhering the spout S to the opening of the container 2, the temporary fixing (point It is preferable to carry out sealing. The container 2 to which the spout S is temporarily fixed as described above is transferred in the same manner as described above by two single containers 2 to which the spout S is temporarily fixed simultaneously when the transfer conveyor 510 further advances. While being held by the container holding bar 512 and the clip 513 of the conveyor 510 and being gripped by the chuck 202 on both sides thereof, it is simultaneously sent to the seal device 207 and between the pair of heat seal dies 210 of the seal device 207 Thus, the lower end opening of the container 2 together with the spout S is completely closed by heat sealing. As shown in FIG. 6D, the heat sealing die 210 of the sealing device 207 has a sealing surface 210a formed in a shape that approximates the outer shape of the bonding portion 13 of the spout S. Further, in this sealing device 207, a sufficient heat sealing time can be secured by heat-sealing the spout S simultaneously with respect to a plurality of containers 2 (two in the illustrated example). The spout S can be securely bonded to the two openings, and the lower end opening of the container 2 can be reliably closed. Next, the container 2 to which the spout S is bonded is sent to the cooling device 208, and is sandwiched between the pair of cooling dies 211 of the cooling device 208, and the lower end of the container 2 to which the spout S is bonded by heat sealing as described above. The edge portion is cooled (see FIG. 6E). In the spout attachment device 201, the container 2 is held in a cylindrical shape by the container holding bar 512 of the transfer conveyor 510, and the posture is fixed by holding the both sides with the chuck 202. Thus, the material is processed in each process while being transferred along with the movement of the moving base unit 511 of the transfer conveyor 510. Thereby, it is not necessary to open the container 2 again when the spout S is inserted, and the spout S can be easily inserted into the opening of the container 2.

  The container 2 in which the spout S is adhered to the lower end opening as described above and the opening is closed further moves together with the transfer conveyor 510 while being held by the chuck 202 on both sides, and the transfer conveyor 510 advances. As the trajectory of the moving base unit 511 is raised, the holding bar 512 is pulled upward from the container 2. After that, the container 2 is sent to the filling device 301 with both sides being held by the chuck 202. In the filling device 301, a container such as an article or a material having fluidity is filled by the feeder 304 from the upper end opening of each container 2 sent as described above (see FIG. 7A). . At this time, since the container 2 is sent to the filling device 301 while the upper end opening is kept open by the chucks 202 on both sides, the container 2 is filled from the upper end opening of the container 2. Is easy. In addition, when filling the contents, a plurality of feeders 304 (two in the illustrated example) are provided in parallel, and the plurality of containers 2 are filled with the contents at the same time, thereby ensuring a filling time. be able to. The container 2 filled with the stored material is sent to the sealing device 302 which is the next process, and the open upper end opening is sandwiched between the pair of heat seal dies 305 of the sealing device 302, The upper end opening is bonded flat by heat sealing (see FIG. 7B), and the upper end of the heat-sealed container 2 is cooled between a pair of cooling dies 306 (FIG. 7C). (See Fig. 7 (d)). When heat sealing and cooling the upper end opening of the container 2 are performed simultaneously on the plurality of containers 2, sufficient heat sealing time and cooling time can be secured. The upper end (the end opposite to the end provided with the spout S) can be reliably closed.

  Thus, each process of the transfer from the bag making process 100 to the spout attachment process 200, the spout attachment in the spout attachment process 200, the filling of the contents in the filling / sealing process 300, and the heat sealing of the opening. , The packaging device M is configured to perform these processes on a plurality of single containers 2 at the same time, so that the heat sealing time, the cooling time of the heat sealing portion, and the filling time of the contents in each step Etc. can be secured sufficiently, and productivity is improved.

  The packaging body 1 obtained as described above is sent to the discharging position in the filling / sealing process, the chuck 202 holding both sides of the packaging body 1 is released and naturally falls downward, and the discharging in the discharging process 400 is performed. It is sent to the next process by the conveyor 401, boxed, etc., and then stored or shipped.

  8 to 11 are representative of a package 1 produced by the packaging method or the packaging apparatus of the present invention, in which a container m having fluidity is filled and sealed in a container 2 having flexibility. The embodiment is shown. In the package 1, the container 2 has a substantially rectangular shape, and a spout S is attached to the short side (upper side) of the outer peripheral shape. As described for the packaging apparatus M shown in FIG. 1, the container 2 is configured by folding and overlapping a flexible film or sheet (web W) and bonding the peripheral portions thereof to each other by heat sealing. ing. The container 2 may be configured by superimposing the two flexible films or sheets and bonding the peripheral portions thereof. When the container 2 is constructed by fusing the peripheral edge by heat sealing, the container 2 is composed of a flexible film or sheet having at least an inner surface made of a thermoplastic material. Therefore, it is preferable that the container 2 is made of a film or sheet in which a thermoplastic resin film is laminated. Furthermore, as described above, the container 2 is composed of a composite laminated film or sheet composed of a thermoplastic resin film and a metal film, or a synthetic resin film or sheet deposited with a metal, from the viewpoint of gas barrier properties. preferable. As the metal film, an aluminum film is common. Moreover, it is preferable from the point of printability with respect to the surface of the container 2 to use the composite laminated | multilayer film or sheet | seat which the outermost layer of the said resin film consists of a polyethylene terephthalate type resin.

  Further, as shown in FIG. 9, the spout S attached to the container 2 has an extraction hole 14 formed therein, and can be divided into an extraction port 11 attached to the container 2 and an extraction port 11. 14, and as shown in FIG. 14, when divided from the extraction port portion 11, it is constituted by a lid portion 12 provided so that the upper end of the extraction hole 14 opens, and the extraction port portion A dividing groove 15 is formed between 11 and the lid portion 12. The spout S is divided by dividing the lid portion 12 from the extraction port portion 11, and as shown in FIGS. 15 and 16, the lid portion 12 is turned upside down by 180 ° and fitted to the extraction port portion 11. It can be sealed. The extraction port portion 11 has an outer surface 16 that is tapered toward the tip, and an inner surface 17 of the lid portion 12 is formed in a taper shape corresponding to the shape of the outer surface 16 of the extraction port portion 11. In addition, the spout S protrudes at least on both sides from the extraction port 11 at the lower part of the extraction port 11 attached to the container 2, and between the two flexible films constituting the container 2. The adhesive part 13 adhere | attached on the inner surface of the opening part 23 (refer FIG. 12) formed in is provided. The bonding portion 13 includes a flange portion 18 projecting at least on both sides from the lower portion of the extraction port portion 11 attached to the container 2 and a peripheral wall portion 19 provided over the entire outer periphery of the lower surface of the flange portion 18. Further, as shown in FIG. 13, the bonding portion 13 is formed in a tapered shape that gradually becomes narrower from the extraction port portion 11 toward both sides thereof. Furthermore, a ridge 20 is formed on the outer surface of the bonding portion 13 along the width direction of the bonding portion 13. The ridges 20 are heated and melted when the spout S is bonded to the openings 23 of the container 2 by heat sealing, so that the openings 23 of the container 2 are reliably closed. In addition, when the lid 12 is divided from the extraction port 11 and attached to the extraction port 11, the lid 12 is inserted into the extraction hole 14 formed in the extraction port 11 to close the extraction hole. A portion 21 is formed, which makes it possible to reliably seal the extraction hole 14. It is preferable that the shaft portion 21 is formed in a tapered shape toward the tip, because the sealing effect of the extraction hole 14 is high. Further, from the outer surface of the lid portion 12 to the side, there is a knob portion 22 for easily twisting the lid portion 12 from the extraction mouth portion 11 with a finger or the like when separating the lid portion 12 from the extraction mouth portion 11. Is formed. The knob 22 protrudes on both sides of the lid 12 along the protruding direction of the bonding portion 13 (the width direction of the container 2) so as not to protrude from the package 1. Although it is preferable that the knob | pick part 22 is plate shape like the example of a figure, it is not limited to this. The spout S is preferably made of a thermoplastic resin that can be bonded to the container 2 by heat sealing, and is formed of, for example, a polyolefin resin such as polyethylene (PE) or polypropylene (PP). Is preferred.

  Although the shape of the container 2 in the packaging body 1 according to the above embodiment is substantially rectangular, it is not limited to this, and for example, various shapes as shown in FIGS. It can also be a container. In this case, the outer shapes of the left and right sides of the container 2 can be formed by the side cutting means 120 in the packaging device M shown in FIG. 1, and the shape of the lower side of the container 2 is the packaging shown in FIG. In the apparatus M, the container 2a formed continuously can be formed by the cutting means 104 that cuts the single container 2 into small parts.

  As described above, in the present invention, in the bag making process 100, the web and the web W composed of the film and the sheet constituting the front and back of the container 2 are folded in two, and the mandrel 106 for forming an opening is formed between the film and the sheet. With the web W open in a cylindrical shape, both sides are bonded together to continuously form the cylindrical container 2a, and a single cutting means 104 is used to keep the cylindrical container 2 open. The container 2 is subdivided, and further transferred to the spout attachment process 200 while the opening state is maintained by the transfer device 500 and the transfer conveyor 510 to attach the spout S to the lower end opening of the container 2, The fluid container is filled from the upper end opening of the container 2 by the filling device 301 in the sealing step 300, and the upper end opening of the container 2 is sealed by the sealing device 302 to obtain the package 1. Thus, according to the packaging method and the packaging apparatus of the present invention, the film constituting the front and back of the container 2 from the beginning of the bag making process of forming the container 2 by bending the web W along its longitudinal direction. Alternatively, a mandrel 106 serving as an opening forming means 105 is provided between the sheets, and the container 2 is continuously formed in a state of being opened in a cylindrical shape, and at the same time, sent to the spout attachment device 201 while maintaining the opened form. Since the adhesive part 13 of the spout S is inserted into and bonded to the opening of the container 2, a relatively small-capacity package that cannot secure a sufficiently wide opening width for inserting and bonding the spout S. Even so, the spout S can be easily attached and the container 2 can be reliably sealed. Therefore, the packaging body of the present invention, which is manufactured by the packaging method or the packaging apparatus as described above, is made of a flexible film or sheet, and the packaging body 2 having the spout S is filled with the fluid packaging material. 1 is the opening width of the container 2 to which the spout S is attached (FIG. 12) with respect to the length of the side (the length indicated by D in FIG. 12) to which the spout S is attached in the outer peripheral shape of the container 2. The length indicated by d) can be 50% or more. Moreover, the length D of the side where the spout S in the outer peripheral shape of the container 2 is attached can be set to 50 mm or less. Furthermore, the length D of the side where the spout S is attached in the outer peripheral shape of the container 2 and the length of the container perpendicular to the side where the spout S is attached (the length indicated by L in FIG. 12). (D / L) to 2/5 or less. Moreover, the opening width d formed by attaching the spout S in the container 2 can be 50 mm or less. In the package 1 of the embodiment shown in FIGS. 8 to 11, the length D of the side to which the spout S is attached is 30 mm, the width of the seal h on both sides is 3 mm, and the spout S is attached. The opening width d of the container 2 is 24 mm. Therefore, the ratio of the opening width d to the length D of the side where the spout S is attached is 80%. The entire outer periphery of the peripheral wall portion 19 of the adhesive portion 13 of the spout S is about 41 mm, and the outer peripheral length of one side of the peripheral wall portion 19 is about 20.5 mm. 68% of the length is inserted and bonded, but according to the packaging method and the packaging device of the present invention, the length D of the side to which the spout S is attached in the container 2 is thus short. Even if the opening width d for inserting the spout S is small, the spout S can be easily attached. Further, the length of the container in the direction orthogonal to the side to which the spout S is attached (the length indicated by L in FIG. 12) is 85 mm, the length D of the side to which the spout S is attached, and the spout The ratio (D / L) to the length L of the container in the direction orthogonal to the side where S is attached is 2/5 or less (30/85 = 6/17). Thus, according to the present invention, it is possible to provide the package 1 having a high appearance, ease of use, and a high filling rate of stored items at a low cost without using complicated processes and packaging devices.

  The packaging method or packaging device according to the present invention fills a package (container) with a small amount of an article or material having fluidity such as liquid, paste, gel or sol at a high filling rate. It can be suitably applied to the production of sealed products.

  The package according to the present invention is suitably used for, for example, oral care products, toiletry products, cosmetics, foods, pharmaceuticals, industrial products, and other products filled and sealed with a relatively small amount of containers having fluidity. Examples of the oral care product include toothpaste, dental rinse, mouse spray, gel toothpaste, plaque check solution and the like. Examples of the toiletry products include shampoos, rinses, treatments, shaving gels, hand soaps, hand creams, body shampoos, facial cleansing creams, hair conditioners, hair restorers, bath preparations, fragrances, liquid detergents and the like. Examples of cosmetics include lotion, whitening cosmetics, nail polish, liquid foundation, and lip balm. Examples of the food include seasonings, dressings, mayonnaise, butter, jam, liquid supplements, jelly, and coffee cream. Examples of pharmaceuticals include ointment creams, eye drops, and itching agents. Examples of industrial products include glues, adhesives, and sealing agents.
