Description

The present invention relates to a beverage server system using a package body that is made of a flexible packaging material and is configured to be attached with a deriving tool for deriving contents after opening.

  In recent years, packaging bodies using flexible packaging materials have been widely distributed so that packaging materials after consuming the contents can be made compact and discarded. On the other hand, in a package in which a liquid, particularly a beverage, is enclosed as the contents, a lead-out tool such as a straw or a spout is often used. The lead-out tool may be attached in advance to the package, but may be separate from the package and may be attached to the package when the contents are consumed. In the latter case, the lead-out tool has a pointed tip, and the contents can be led through the lead-out tool by making a hole in the packaging material at the tip and piercing the lead-out tool (for example, Patent Document 1). reference).

JP 2007-176597 A

  In the above-described conventional packaging body, the lead-out tool penetrates the packaging material in the thickness direction so that the tip portion enters the inside of the packaging body, so the area where the packaging material and the lead-out tool are in contact with each other is very small. Moreover, the way of perforating is not constant depending on how the lead-out tool is pierced. For this reason, there is a possibility that the lead-out tool is not sufficiently held or the contents leak from between the lead-out tool and the packaging material.

An object of the present invention is to provide a beverage server system that uses a package that sufficiently holds a lead-out tool that is mounted after opening, and that prevents the contents from leaking between the lead-out tool and the package.

The beverage server system of the present invention is made of a flexible packaging material, and a package configured to open a sealed portion that encloses contents by cutting a part of the packaging material. and body,
A rigid container for storing the package;
A beverage server on which the rigid container is installed;
A tube serving as a lead-out tool that is inserted into an opening formed in the package by cutting a part of the packaging material and connected to the beverage server.

In the beverage server of the present invention, the packaging material may be formed by packaging at least a part of the outer periphery of the packaging material such that the enclosing portion has an extended portion that locally projects toward an edge of the packaging material. When the inner surfaces facing each other are joined, and the extension part is inserted into the opening from the opening formed by cutting the packaging material at a position crossing the extension part for opening. In addition, the packaging material is formed with a dimension that gives a tension in the circumferential direction of the tube.

Furthermore, in the beverage server of the present invention, two discs that also serve as handles are attached to the outer surface of the rigid container so as to be parallel to each other, and the beverage server is connected to the outer periphery of the two discs. It has two support members which are installed at a position corresponding to the surface and in which an arc-shaped recess having a radius of curvature equal to the radius of curvature of the disk is formed on the upper surface.

  According to the present invention, in the state in which the lead-out tool is inserted from the opening formed by cutting the packaging material, the inner surface of the packaging material is the outer periphery of the lead-out tool in the portion where the lead-out tool of the extension portion is inserted. The lead-out tool is held in a range having a length in the insertion direction while being in close contact with the surface. As a result, the lead-out tool can be held with a sufficient holding force, and the content hardly leaks between the packaging material and the lead-out tool.

  Referring to FIG. 1, there is shown a cross-sectional view of a package 100 made from a flexible packaging material and enclosing contents according to one embodiment of the present invention. For example, a laminate film having a thermoplastic resin layer can be used as the packaging material, and one packaging material is folded or two packaging materials are overlapped with each other so that the thermoplastic resin layer faces each other. In addition, the thermoplastic resin layers facing each other are joined to each other at a predetermined location by heat welding, and thus formed into a bag shape. The contents are enclosed in an enclosure 101 that is a sealed region surrounded by a joint 103 formed by heat welding of the packaging material.

  As a form of the packaging material, a sheet-like film can be used as described above, but an inflation film previously formed into a tube shape can also be used. Further, the bonding of the packaging material is not limited to heat welding, but may be ultrasonic welding.

  The shape of the enclosure part 101 may be arbitrary. However, in this invention, the enclosure part 101 has the extension part 102 which protruded and extended locally toward the edge of a packaging material. The packaging material is not joined in the enclosing portion 101 including the extension portion 102.

  The package 100 can be opened by cutting a part of the packaging material. Therefore, in the package 100, a notch 104 that indicates a cutting start position of the packaging material when the package 100 is opened is formed in the upper end portion of the package 100. The notch 104 is formed at a position where the cutting of the packaging material proceeds so as to cross the extension 102 as shown by a one-dot chain line in FIG. 1 when the packaging material is cut for opening. An end portion of the extension 102 opened by cutting the packaging material becomes an opening. It can be said that the opening is a portion that passes through the extension 102 when the packaging material is cut before the package 100 is opened.

  In FIG. 1, a notch 104 is formed on each side in the width direction at the upper end of the package 100 as a cutting assisting means for indicating the cutting start position of the package 100 when opened, but the notch 104 is formed only on one side. May be formed. Further, the cutting assisting means is not limited to the notch 104, and may be arbitrary as long as it can be visually recognized by the consumer, such as a notch or a mark printed on the packaging material. However, the packaging material can be cut even without the opening assisting means, and the opening assisting means is not an essential configuration for the present invention.

  The package 100 of the present embodiment encloses, for example, 100 to 200 ml of beverage as the contents, and a straw 150 that is a lead-out device that leads out the beverage to the outside of the package 100 in order to drink the enclosed beverage. Is used. The entire straw 150 is formed in a cylindrical shape. The straw 150 may be attached to the package 100 by putting it in a bag (not shown) and bonding the bag to the package 100, or may be provided separately from the package 100.

  When drinking a beverage enclosed in the package 100, the consumer first cuts the packaging material from the notch 104 in the width direction of the package 100. When the cutting of the packaging material proceeds to a position at least passing through the extension 102, the opening is opened. The consumer may stop cutting the packaging material when the opening is opened, or cut the packaging material to the end on the side where the other notch 104 is formed, and cut the upper end of the packaging material. Also good. In FIG. 2, the package 100 in the state which cut off the upper end part of the packaging material is shown. The cutting of the packaging material may be performed by the consumer tearing the packaging material by hand or using a blade.

  When the opening is opened, the consumer inserts the straw 150 into the enclosure 101 from the opening as shown in FIG. At this time, the straw 150 passes through the extension portion 102 and enters the enclosure portion 101.

  The width of the extension portion 102 is set such that when the straw 150 is inserted, a tension in the circumferential direction of the straw 150 is applied to the packaging material by the outer peripheral surface of the straw 150. As a result, in a state where the straw 150 is inserted into the packaging body 100, the inner surface of the packaging material is in close contact with the outer peripheral surface of the straw 150 at the portion of the extension 102 where the straw 150 is inserted. In addition, since the extension portion 102 is configured by the facing portion of the packaging material and has a length in the direction in which the straw 150 is inserted, the extension portion 102 has a length range in which the extension portion 102 extends. The straw 150 can be held. Therefore, for example, even when the consumer 100 grips the packaging body 100 and the packaging body 100 is pressurized from the outside, the contents are passed from the opening through the packaging material and the straw 150. There is almost no risk of leakage.

  In order to prevent the contents from leaking at the time of opening, the packaging material is cut in a posture with the extension 102 facing upward, and when it is in that posture, the content moves downward under its own weight, and at least the extension portion The contents are enclosed in the package 100 by an amount that does not exist at the cutting position above 102. Therefore, when the packaging material is cut for opening, the inner surfaces of the packaging material facing each other at the extension 102 are almost in contact with each other, and the straw 150 may be difficult to insert.

  Therefore, in order to facilitate the insertion of the straw 150 from the opening of the extension portion 102 when opening, when the leading end, which is the end portion of the extension portion 102 on the opening side, opens the package 100, as shown in FIG. It is preferable that the wrapping material is crushed so that the space between the wrapping materials is widened to form a bulge. It is not necessary to perform the caulking so that the packaging material has a shape that matches the shape of the outer peripheral surface of the straw 150 inserted from the opening formed by cutting the extension portion 102, and the tip of the straw 150 is inserted. It is sufficient that the opening is made so that it can be opened.

  The wrapping to the packaging material can be performed before the packaging material is joined at least on the distal end side of the extension 102. For example, in the state in which the packaging material is softened by heating in the portion to be the extension portion 102, the inner surface of the packaging material is pressed against the outer circumferential surface of the columnar member to place the packaging material on the circumferential surface of the column member. And a method of plastically deforming the packaging material and cooling the packaging material to room temperature in that state.

  Moreover, the shape of the front-end | tip part of the extension part 102 is made into the taper shape (for example, the shape shown by FIG. 14) from which the width | variety of the extension part 102 becomes wide as it goes to the edge of a packaging material, For opening in this taper-shaped part By cutting the packaging material, the straw 150 can be inserted more easily through the opening.

  The extension part 102 can fully exhibit the function of making the contents difficult to leak by defining the width as described above in relation to the inserted straw 150. This is the same even when a spout 250 is used as a lead-out tool in a package 200 having a relatively large capacity (for example, 1 to 2 liters) as shown in FIGS. The packaging body 200 shown in FIGS. 5 and 6 is different from the packaging body 100 shown in FIG. 1 in overall shape and size, including the enclosing portion 201, the extension portion 202, the joint portion 203, the notch 204, and the like. The relationship between the extension 202 into which the spout 250 is inserted and the portion to be inserted into the extension 202 of the spout 250 is the same as that shown in FIG.

  In the spout 250 used in this embodiment, a portion inserted into the extension portion 202 is formed in a cylindrical shape, and a distal end side inserted into the package 200 is tapered. An opening 252 for leading out the contents is formed on the side surface that is tapered. A double flange 251 serving as a stopper at the time of insertion into the package 200 is formed at an intermediate portion in the axial direction of the spout 250. In addition, a cap 253 is detachably attached to the end of the spout 250 opposite to the side inserted into the package 200, so that the opened package 200 can be resealed. Note that the spout 250 is not limited to the one having the configuration shown in the figure, and any spout can be used. For example, a spout having a one-way valve can be used so that air is not introduced into the package 200.

  Since the spout 250 can be washed and reused, after the contents are consumed, the spout 250 can be removed from the package 200 and only the empty package 200, that is, the packaging material can be discarded. Since the packaging material is flexible, it can be discarded in a compact state by being rolled or folded. Further, by reusing the spout 250, waste can be reduced and resources can be saved.

  By the way, when the contents are poured out from the package 200 in the relatively large-capacity package as described above, the package 200 is tilted so that the spout 250 faces downward. Since the spout 250 is only inserted and held in the extension portion 202, if the adhesion between the extension portion 202 and the spout 250 is not sufficient, when the spout is turned downward, the spout 250 is not positioned between the spout and the extension portion. It is conceivable that the contents leak from the opening through the opening.

  Therefore, for example, as shown in FIG. 7, it is preferable that the extension 202 has a shape having a narrow portion. The shape of the extension portion 202 is at least one that projects the shape of the joint portion 201 of the packaging material for forming the extension portion 202 toward the inner side in the width direction of the extension portion 202 at the boundary with the extension portion 202. It can obtain by making it the shape which has the one protrusion part 201a.

  When the spout 250 is inserted into the extension portion 202, a gap may be formed between the spout 250 and the extension portion 202 at both side edges in the width direction of the extension portion 202, that is, at the boundary between the joint portion 201 and the non-joint portion of the packaging material. There is sex. Therefore, as described above, by joining the packaging material so as to have a portion where the width of the extension portion 202 becomes narrower, the extension portion 202 can more reliably seal between the spout 250 and the packaging material. . It is preferable that the height of the protruding portion 201a formed in order to narrow the width of the extension portion 202 is less than 3 mm so that the insertion of the spout 250 into the extension portion 202 does not become difficult. In addition, the packaging material may be peeled off at the protruding portion 201a by the insertion of the spout 250 into the extension portion 202.

  In order to ensure better sealing performance, it is preferable that the protrusions 201 a are formed on both sides of the extension 202 in the width direction. For smooth insertion of the spout 250, the protrusions 201a are preferably formed at opposite positions on both sides of the extension 202 in the width direction. The position and number of the protrusions 201a are not particularly limited. In the case of having a plurality of protrusions 201a, the same number of protrusions 201a may be disposed on both sides in the width direction of the extension 202, or a different number of protrusions 201a may be disposed. Further, the protruding portion 201a may be disposed only on one side in the width direction of the extension portion 202.

  Next, an embodiment of the method for manufacturing a package and the manufacturing apparatus according to the present invention will be described taking as an example the case of manufacturing the package 200 shown in FIG.

  Referring to FIG. 8, a filling and packaging machine 1 according to an embodiment of the present invention is shown. Moreover, the state of the film from supply of a film to completion of a packaging body for demonstrating how the packaging body 200 is manufactured from a film is shown in FIG.

  The filling and packaging machine 1 shown in FIG. 8 forms the film 8 in a bag shape by joining the inner surfaces of the films 8 at predetermined positions while feeding the long film 8 with the inner surfaces to be joined facing each other. However, it is configured to produce a package in which the contents are enclosed. Here, the case where an inflation film is used as the film 8 and a package in which a liquid is enclosed as the contents is manufactured will be described as an example. The inflation film immediately presses a tube-shaped film formed at a high temperature into a flat shape to bring the inner surfaces into close contact with each other. Therefore, the inner surface of the film is extremely clean, which is suitable when the content is food or beverage.

  The filling and packaging machine 1 includes a film supply unit that rotatably supports a film 8 wound on a roll, a top side belt cutter unit 10, a tacking unit 20, a top corner welding unit 30, a top center welding unit 40, and a top corner cutter unit. 50, a bottom side belt cutter unit 60, a bottom corner welding unit 70, a bottom corner cutter unit 80, an end welding unit 90, and an individual cutter unit 95. The film 8 fed out from the roll in the film supply section passes through the above units in order by the first to third feed rollers 3, 4, 5 and an appropriate guide roller disposed between them. Be transported. Among the above units, all the units except the top side band cutter unit 10 and the bottom side band cutter unit 60 are operated in a state where the feeding of the film 8 is temporarily stopped. Among the above units, the respective welding units such as the top corner welding unit 30, the top center welding unit 40, the bottom corner welding unit 70, and the end welding unit 90 join the inner surfaces of the film 8 in a plurality of stages. A plurality of joining means are configured.

  The fed film 8 is first fed by the top side belt cutter unit 10 so that the top side belt, which is the edge of the film 8 corresponding to the upper part of the packaging body 200 (the end on the side where the lead-out tool is mounted), is the film feeding direction. (S11). The top side belt cutter unit 10 has a cutter disposed at the edge of the film 8 so as to face the conveyance path of the film 8, and the film 8 passes through this cutter as the film 8 is fed. Can be removed along the feeding direction of the film 8. This also opens one end of the film 8 in the width direction, which is the film (inflation film) 8 corresponding to the upper side of the package 200. The film 8 from which the top side band has been cut is temporarily stopped at the position where the tacking unit 20 is disposed, and the part of the film 8 corresponding to the extension 102 of the package 200 is operated by operating the tacking unit 20 here. The above-described clinging is performed (S12).

  Hereinafter, one form of the kneading unit 20 will be described with reference to FIGS.

  The kneading unit 20 according to one embodiment of the present invention can have a pair of heating bars 21 arranged opposite to each other and a round shaft member 24 serving as a kneading mold. The round shaft member 24 is configured to be able to advance and retreat between the film inner surfaces facing each other from the end side of the film opened by the top side band cutter unit 10 (see FIG. 8). The diameter of the round shaft member 24 is not particularly limited as long as the diameter is such that the tip of the spout 250 can be inserted when the package 200 is opened. Each of the pair of heating bars 21 has a built-in heater, and is configured to be able to advance and retract in a direction in which the round shaft member 24 approaches and separates from each other. As shown in FIG. 11, arc-shaped concave portions 21 a having a radius of curvature equal to the radius of curvature of the outer peripheral surface of the round shaft member 24 are located on the opposing surfaces of the respective heating bars 21 at positions corresponding to the round shaft member 24. Is formed.

  When the film is kneaded by the kashing unit 20 configured as described above, the round shaft member 24 is first inserted between the films facing each other with the film feeding stopped. Next, as shown in FIG. 12, the heating bars 21 are advanced so as to approach each other, and the film 8 is pressed against the outer peripheral surface of the round shaft member 24. In the pressed film 8, a portion sandwiched between the round shaft member 24 and the concave portion 21 a of the heating bar 21 is curved along the outer peripheral surface of the round shaft member 24, and is softened by heat from the heating bar 21 in this state. The time for pressing the film 8 against the round shaft member 24 by the heating bar 21 is sufficient for the film 8 to be softened. After the film 8 is softened, the heating bar 21 is retracted in a direction away from the round shaft member 24. Since the film 8 is softened, even if the heating bar 21 is separated from the film 8, the curved shape of the film 8 is maintained. In this state, the film 8 is cooled to room temperature, whereby the film 8 can be attached.

  In order to be able to cool the film 8 more effectively, the tacking unit 20 can further include a cooling bar. In the present embodiment, the pair of cooling bars 22 disposed so as to face each other with the round shaft member 24 interposed therebetween is configured to be capable of moving forward and backward in a direction approaching and separating from each other. As with the heating bar 21, the cooling bar 22 is formed with an arc-shaped recess 22 a (see FIG. 11) having a radius of curvature equal to the radius of curvature of the outer peripheral surface of the round shaft member 24 on the opposing surfaces. The film 8 can be effectively cooled by cooling the film 8 while pressing the film 8 against the outer peripheral surface of the round shaft member 24 by the concave portion 22a. In addition, since the curved state of the film 8 is maintained, it is possible to achieve better scuffing.

  In this embodiment, as shown in FIG. 10, the heating bar 21 and the cooling bar 22 are opposed to each other on a base 25 provided so as to be movable in a direction perpendicular to the opposing movement direction of the heating bar 21 and the cooling bar 22. It supports to move forward and backward. The heating bar 21 and the cooling bar 22 can be operated independently from each other by separate driving sources, or both can be operated by a common driving source. With this configuration, first, the heating bar 21 is operated with the base 25 moved to a position where the pair of heating bars 21 face the round shaft member 24 to soften the film, and then one cooling bar 22 is round. By moving the base 25 to a position facing the shaft member 24 and operating the cooling bar 22 in this state, the softened film can be solidified.

  The tacking unit 20 can also have a pair of film pressers 23. The film presser 23 is a mechanism for holding the film so that the film does not become slack when at least the heating bar 21 presses the film against the round shaft member 24.

  One form of the film presser 23 will be described with reference to FIG. The film presser 23 has a pair of bases 231 arranged to face each other with the round shaft member 24 interposed therebetween. The base 231 is configured to be able to advance and retreat in a direction approaching and separating from each other. The base 231 can be operated together with the heating bar 21. Therefore, if the base 231 is connected to the heating bar 21 as shown in FIG. 10, a drive source for the operation of the base 231 is unnecessary.

  Two arms 232 and 233 are supported on each base 231. Each arm 232, 233 is supported so that the end thereof is swingable in the feeding direction of the film 8, and one arm 232 extends upward of the round shaft member 24 so that the distance between the arms 232, 233 increases toward the tip. The other arm 233 extends downward from the round shaft member 24. These two arms 22 and 233 are connected by a spring 235 so as to be urged in a direction in which the distance between them becomes narrow. A pad 234 that comes into contact with the film 8 is swingably supported at the tips of the arms 232 and 233. As shown in FIG. 10, the positions, lengths, angles, and thicknesses of the pads 234 are set so that the tip surface of the pad 234 protrudes from the tip surface of the heating bar 21. Has been.

  The film presser 23 configured as described above operates as follows.

  In the state shown in FIG. 10 before the operation of the heating bar 21, the pair of film pressers 23 are separated from each other. When the heating bar 21 operates and advances in the approaching direction, the film presser 23 also advances in the approaching direction at the same time. By advancement of the heating bar 21 and the film presser 23, the film 8 is clamped above and below the round shaft member 24 by the pad 234 of the film presser 23 before the heating bar 21.

  Since the arms 232 and 233 to which the pads 234 are attached are swingably supported by the base 231, the heating bar 21 resists the urging force of the spring 235 even after the film 8 is clamped by the pads 234. Then, the arm 232 and 233 can be moved while moving until the film 8 is sandwiched with the round shaft member 24. By the advancement of the heating bar 21 after the film 8 is sandwiched between the pads 234, the distance between the pads 234 sandwiching the film 8 in the vertical direction of the round shaft member 24 is expanded. Thereby, since the film 8 is pulled up and down on the upper and lower sides of the round shaft member 24, the film 8 can be creased without causing wrinkles.

  Referring to FIGS. 8 and 9 again, after completion of the brazing, the film 8 is fed again, and then the feeding of the film 8 is temporarily stopped at the position where the top corner welding unit 30 is disposed. Here, by operating the top corner welding unit 30, the part of the film 8 corresponding to the upper corner portion of the package 200 is thermally welded (S13). The top corner welding unit 30 includes a heater bar having a pressurizing surface corresponding to the welding shape of the film 8 at the upper corner portion of the package 200, and a heater bar receiver disposed opposite to the heater bar with the film 8 interposed therebetween. Have. By pressing and heating the film 8 with the heater bar and the heater bar receiver, the upper corner portion of the package 200 is thermally welded.

  After completion of the thermal welding of the upper corner portion, the film 8 is fed again, and then the feeding of the film 8 is temporarily stopped at the position where the top center welding unit 40 is disposed. Here, by operating the top center welding unit 40, the portion of the film 8 outside the portion soldered by the tacking unit 20 between the portions thermally welded by the top corner welding unit 30 is thermally welded. (S14). The top center welding unit 40 includes a heater bar having a pressurizing surface corresponding to the welding shape of the film 8 between the upper corners of the package 200, and a heater bar receiver disposed opposite to the heater bar with the film 8 interposed therebetween. And have. The extension part 202 of the package 200 is formed by pressurizing and heating the film 8 with the heater bar and the heater bar receiver.

  In this embodiment, the top portion of the package 200 is thermally welded in two portions using the top corner welding unit 30 and the top center welding unit 40, but may be collectively performed by one welding unit. it can. As described above, the top welded portion 213 is formed. The top welding portion 213 includes not only the case where the top corner welding unit 30 and the top center welding unit 40 are heat-welded but also the case where heat welding is performed collectively.

  After the thermal welding by the top center welding unit 40 is completed, the film 8 is fed again, and then the feeding of the film 8 is temporarily stopped at the position where the top corner cutter unit 50 is disposed. Here, by operating the top corner cutter unit 50, the top cut portion 211 which is the portion of the film 8 outside the portion thermally welded by the top corner welding unit 30 and the top center welding unit 40 is removed (S15). . In addition, when the shape of the upper part of the package to be manufactured does not need to cut out the film 8 such as a rectangular shape having a uniform width, the top corner cutter unit 50 is unnecessary.

  After removing the top cut portion 211, the film 8 is sent again. A bottom side band cutter unit 60 is disposed downstream of the top cutter unit 50 in the feeding direction of the film 8. The bottom side band cutter unit 60 has the same configuration as the top side band cutter unit 10 and is disposed on the opposite side of the top side band cutter unit 10 in the width direction of the film 8. When the film 8 passes through the bottom side band cutter unit 60, the bottom side band, which is the edge of the film 8 corresponding to the lower part of the package (the end opposite to the side where the lead-out tool is mounted), It is removed along the feed direction (S16). This also opens the other end of the film 8 in the width direction, which is the film (inflation film) 8 corresponding to the lower side of the package.

  The film 8 from which the bottom side band has been removed by the bottom side band cutter unit 60 is sent downward. While the film 8 is fed downward, the remaining part of the film 8 is thermally welded and the contents are charged.

  The contents are input through the input pipe 2. As shown in FIG. 9, the charging pipe 2 is inserted between the facing films 8 from the end side of the film 8 opened by the bottom side band cutter unit 60, and the lower end extends downward.

  A bottom corner welding unit 70 is disposed below the position where the charging pipe 2 is inserted. When the portion of the film 8 facing the portion heat-welded by the top corner welding unit 30 is sent to the position where the bottom corner welding unit 70 is disposed, the feeding of the film 8 is temporarily stopped. Here, by operating the bottom corner welding unit 70, the portion of the film 8 corresponding to the lower corner portion of the package 200 is thermally welded (S17). The bottom corner welding unit 70 includes a heater bar having a pressing surface corresponding to the welding shape of the film 8 at the lower corner portion of the package 200, and a heater bar receiver positioned opposite the heater bar between the film 8. And have. By pressurizing and heating the film 8 with the heater bar and the heater bar receiver, the lower corner portion of the package 200 is thermally welded. In this way, the bottom welded portion 214 is formed.

  The bottom corner cutter unit 80 is disposed below the bottom corner welding unit 70. After the thermal welding by the bottom corner welding unit 70 is completed, the film 8 is fed again, and then the feeding of the film 8 is temporarily stopped at the position where the bottom corner cutter unit 80 is disposed. Here, by operating the bottom corner cutter unit 80, the bottom cut portion 212, which is the portion of the film 8 outside the portion thermally welded by the bottom corner welding unit 70, is removed (S18). In addition, when the shape of the lower part of the package to be manufactured does not need to cut out the film 8 such as a rectangular shape having a uniform width, the bottom corner cutter unit 80 is unnecessary.

  In the series of steps so far, the top part of the package 200 is formed first, and then the bottom part is formed. However, this order may be reversed. Further, in order to perform heat welding that does not cause wrinkles and to cut the film 8 at an accurate position, it is preferable that the top portion and the bottom portion of the package 200 are formed as flat as possible. Therefore, it is preferable that the lower end of the charging pipe 2 is positioned below the bottom corner cutter unit 80 as shown in FIG.

  Through the above steps, the contents are charged by the charging pipe 2 into the film 8 on which the top welding part 213 and the bottom welding part 214 are formed.

  An end welding unit 90 is disposed below the charging pipe 2. After removal of the bottom cut portion 212, the film 8 is fed again. Next, when the portion corresponding to the boundary portion of each package 200 is sent to the position where the end welding unit 90 is disposed, the film 8 is fed. Paused. Here, by operating the end welding unit 90, a portion corresponding to the boundary portion of each package 200 is thermally welded (S19).

  The end welding unit 90 includes a heater bar having a pressing surface extending in the width direction of the film 8 across the top welding part 213 and the bottom welding part 214, and a heater bar receiver disposed opposite to the heater bar with the film 8 interposed therebetween. And have. By pressurizing and heating the film 8 with the heater bar and the heater bar receiver, the portion of the film 8 between the top welded portion 213 and the bottom welded portion 214 is thermally welded, whereby the end welded portion 215 is formed. The

  By the end welding part 215, the enclosure part 101 (refer FIG. 5) of each packaging body 200 is formed. By performing so-called submerged sealing that operates the end welding unit 90 in a state where the contents are charged up to a height exceeding the end welding unit 90, the package 200 is manufactured without air existing in the sealed portion 101. Can do. At this time, the heater bar and the heater bar receiver of the end welding unit 90 pressurize the portion of the film 8 swollen by the contents. Excessive bulging is undesirable for proper heat welding. Therefore, so that the heat welding can be performed in a state where the swelling of the film 8 is as small as possible, the interval between the top welded portion 213 and the bottom welded portion 214 is narrowed to such an extent that does not hinder the placement of the input pipe 2. It is preferable that the shapes of the top welding part 213 and the bottom welding part 214 are designed.

  After the end welded portion 215 is formed, the film 8 is sent again. Next, when the end welded portion 215 is sent to the position where the individual unit 95 is disposed, the feeding of the film 8 is temporarily stopped. The unit 95 can be operated. The individual division unit 95 has a cutter that cuts the film 8 over its entire width in the width direction. By the operation of the individual division unit 95, the film 8 is the full width in the width direction of the film 8 at the portion where the end welded portion 215 is formed. Thus, individually separated packages 200 are obtained (S20).

  The present invention has been described using several embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

  The form of the package is not limited to the above-described four-side seal type package, but may be a form having a part to be joined facing the packaging material, such as a three-side seal type, a pillow type, a standing pouch type, and a gable top type. It can be applied to any form of package. Moreover, the size of the package can also be applied to various size packages from a small size having an internal volume of about 100 ml to a large size of about 20 liters. The contents enclosed in the package may be any contents as long as they can be led to the outside through a leading tool such as a straw or a spout, and in particular, liquids, pastes, viscous materials, powders, etc. The present invention can exert an excellent effect on contents having fluidity.

  Moreover, although the inflation film was used as a packaging material in the form mentioned above, a sheet-like film can also be used. When using a sheet-like film, the top-side belt cutter unit 10 and the bottom-side belt cutter unit 60 are not necessary. Instead, one sheet-like film is folded in two along the longitudinal direction or formed into a cylindrical shape. A bag making guide (not shown) is provided. Alternatively, two sheet-like sheets can be supplied facing each other.

  Below, the other form of the package which applied this invention is demonstrated.

(Gable Top 1)
The form shown in FIG. 14 is a case where the present invention is applied to a gable top type package 300 having an internal volume of, for example, 500 ml. The contents are beverages. In many cases, the gable-top type package is made so as to be self-supporting by a paper container. However, even if a flexible packaging material such as a film is used, four sides extending in the vertical direction are defined as hem seals 306. It can be made independent. The package 300 is provided with a two-stage stretchable straw 350 as a lead-out tool. The package 300 has a tab 305 for opening at the upper end, and is configured to be opened when the tab 305 is cut off. In order to assist excision of the tab 305, a cut indicating a cutting start position is formed. This cut is formed at a position where the packaging material is cut at a position passing through the extension 202 extending locally from the enclosing portion 301. Since the structure for opening the package 300 is the same as that described above, detailed description thereof is omitted here.

  When the tab 305 is removed, an opening is formed in the extension 302, and when the straw 350 is inserted from the opening, the straw 350 is held by the extension 302, and a beverage can be drunk using the straw 350.

(Gable Top 2)
A package 400 shown in FIG. 15 is a gable-top type package 400 configured similarly to the package 300 shown in FIG. However, the internal capacity is large, for example, about 1 liter, and the contents are consumed in multiple times by being transferred to another container. Suitable contents are beverages, liquid seasonings and the like. A spout 450 is used as the deriving tool. Although a spout 450 with a cap is shown in FIG. 15, a spout with a one-way valve may be used so that air is not introduced into the package through the spout 450. By opening the tab 405 of the package 400, an opening is formed in the extension 402. When the spout 450 is inserted from the opening, the spout 450 is held by the extension 402. The contents can be poured out of the spout 450 by tilting the package 400 with the spout 450 mounted on the package 400. Since the outer surface of the spout 450 is held in close contact with the packaging material, the contents do not leak from between the spout and the packaging material.

(Store in rigid container)
For example, FIG. 16 shows a mode in which a large-capacity package 200 as shown in FIG. 5 is stored in a rigid container for storage.

  In FIG. 16, as the package 200 and the spout 250, those configured similarly to those shown in FIG. 5 can be used. The inner volume of the package 250 can be, for example, about 1 to 2 liters, and the content can be, for example, a beverage such as mineral water. Generally, the three-side seal type or the three-side seal type package 200 cannot be self-supported because the packaging material itself has flexibility, and is stored in a laid state. Therefore, when the package 200 has a large capacity, a suitable storage space is required.

  Therefore, by using a rigid container for storing such a package 200, the package 200 can be stored in an upright state. In addition, the package 200 can be protected from damage due to external force.

  In the form shown in FIG. 16, the rigid container has a container body 510 and a lid member 520. The container main body 510 is formed in a size that can be stored in a state where the package 200 is stood up. The height of the container body 510 is equal to or less than the height at which the portion of the spout 250 exposed to the outside of the package 200 protrudes from the container body 510 when the package 200 with the spout 250 attached is stored in the container body 510. It is preferable that The spout 250 has a double flange 251 formed at the lower end of the portion exposed from the package 270. Further, the spout 250 can be resealed by the cap 253.

  The lid member 520 is detachably fixed to the container body 510. A spout holding hole 521 is formed on the top surface of the lid member 520 at a position facing the spout 250 when the lid member 520 is fixed to the container main body 510 containing the package 200. The spout holding hole 521 has a first portion 521a and a second portion 521b continuous therewith. The first portion 521a is a portion opened with a size larger than the planar size of the double flange 251 so that the double flange 251 of the spout 250 can pass freely. The second portion 521b is a portion configured to hold the spout 250 in the double flange 251 by sliding the spout 250 from the first portion 521a in the in-plane direction of the double flange 251. . In order to hold the spout 250 with the double flange 251, the second portion 251 b can have a protrusion protruding into the spout holding hole 521 as shown in FIG. 16. The protrusion is formed with a dimension that can be received between the double flanges 251 that have been slid from the first portion 521a. Alternatively, the second portion 521b of the spout holding hole 521 is formed in a size smaller than the planar size of the double flange 251 and a portion smaller than the planar size of the double flange 251 is formed from the first portion 521a. You may make it form in the dimension accepted between the double flanges 251 which have slid.

  In order to make the lid member 520 hold the spout 250 by configuring the lid member 520 and the spout 250 as described above, first, the spout 250 is placed in the first portion 521a of the spout holding hole 521 and the double flange 251. However, it inserts until it becomes the substantially same position as the top | upper surface of the cover member 520 in the axial direction of the spout 250. FIG. Next, the spout 250 is slid to the second portion 521b. At this time, the spout 250 can be held by the lid member 520 by sliding the portion of the second portion 521b that is received between the double flanges 251 so as to enter between the double flanges 251. The spout 250 may be held on the lid member 520 before or after the lid member 520 is fixed to the container main body 510.

  When the holding of the spout 250 to the lid member 520 and the fixing of the lid member 520 to the container body 510 are completed as described above, the cap of the spout 250 is then removed, and the container body 510 is tilted to remove the contents. The same handling as a general plastic bottled beverage, such as pouring out, becomes possible. However, in this embodiment, since the beverage is enclosed in the package 200 and only the package 200 can be discarded after the beverage is consumed, waste can be reduced and compact disposal is possible. Become. Moreover, since the container main body 510, the lid member 520, and the spout 250 can be reused, it also helps to save resources.

(Beverage server bag)
The package according to the present invention can also be used as a bag for a beverage server. 17A to 17E show an embodiment in which the package according to the present invention is used as a bag for a beverage server. The internal volume of the package 600 is, for example, 8 to 20 liters, and the configuration other than the internal volume is configured similarly to the package described in the above-described form.

  As shown in FIG. 17A, the package 600 is used in a rigid container. The main reason for using the package 600 in a rigid container is to protect the package 600 from external forces and to stabilize the shape of the package 600 so that the drinking water in the package 600 can be used as efficiently as possible. Is to do so. The rigid container has a container body 610 and a lid member 620. The container main body 610 and the lid member 620 have an arbitrary fixing structure for preventing the lid member 620 from being detached from the container main body 610. The lid member 620 is formed with an opening 621 for taking a portion around the opening of the package 600, for example, a portion having the extension 602, out of the container. Two discs 612 that also serve as handles are attached to the outer peripheral surface of the container main body 610 so as to be parallel to each other.

  After the package 600 is stored in the container body 610 and the lid member 620 is fixed to the container body 610 with the extension 602 extended, the tab 605 of the package 600 is cut away as shown in FIG. 17B. The leading end of the connecting tube 650 connected to the server body is inserted from the opening opening thus opened. The distal end portion of the connection tube 650 may have the same structure as the portion inserted into the spout package described above, whereby the connection tube 650 has the distal end portion connected to the extension portion 602 of the package body 600. Retained. Thus, the tank assembly 660 having the package 600, the tube 650, the container main body 610, and the lid member 620 is obtained.

  Normally, as in each of the above-described forms, the lead-out part can be sufficiently retained simply by inserting a lead-out tool such as a spout or a straw into the extension part, but it is packaged as a beverage server beverage bag as in this form. When using the body, as will be described later, since the packaging body is in a posture with the connection portion with the outlet tool facing downward while being set in the beverage server, the outlet tool is more securely held by the packaging body. Is required.

  Therefore, it is preferable to use a clip 670 configured to sandwich the package 600 at the portion where the tube 650 is inserted as shown in FIG. 17C. The clip 670 has clip surfaces facing each other in order to sandwich the package 600, and a concave portion corresponding to the outer peripheral surface shape of the portion of the tube 650 inserted into the extension 602 of the package 600 is formed on the clip surface. Has been. By using such a clip 670 and sandwiching the extension portion 602 in which the tube 650 is inserted, it is possible to reliably prevent a beverage from leaking from the connection portion of the tube 650.

  After the clip 670 is installed, the tank assembly 660 is installed in the beverage server 700 as shown in FIG. 17D. The beverage server 700 is configured such that the tank assembly 660 is installed on the top thereof, and has two support members 710 that support the tank assembly 660. The support member 710 is installed at a position corresponding to the outer peripheral surface of the disc 612 attached to the container body 610, and an arc-shaped recess having a radius of curvature equal to the radius of curvature of the disc 612 is formed on the upper surface thereof. ing. Accordingly, the tank assembly 660 supported by placing the disk 612 in the recess is rotatably supported with the center of the disk 612 as a fulcrum. The tank assembly 660 supported with the connection portion between the tube 650 and the packaging body 600 facing upward is rotated 180 degrees as shown in FIG. 17E, so that the connection portion between the tube 650 and the packaging body 600 is placed on the lower side. It is made to face. After the tank assembly 660 is rotated, the tank assembly 660 is fixed to the beverage server 700 by an appropriate fixing means, whereby the installation of the tank assembly 660 is completed.

  After the tank assembly 660 is installed, it can be used like a normal beverage server. Since the outer peripheral surface of the tube 650 and the packaging material are in good contact with each other at the connection portion between the tube 650 and the package 600, the beverage does not leak from the package 600.

  After the consumption of the beverage, the package 600 is taken out from the container body 610 by a procedure reverse to the procedure described above, and the tube 650 is further pulled out from the package 600. Since only the package 600 needs to be discarded, the waste can be reduced and the package can be discarded in a compact manner. Moreover, since only the minimum members are discarded, resources can be saved.
