For example, self-disclosed in JP-A-2005-15029 and JP-A-2005-59958 The nozzle having a seal non-return function, and preferably, the melting point of the sealant layer on the opposite inner surface side of the laminated film on each side of the front and back constituting the liquid pouring nozzle is set to the outermost layer of the liquid pouring nozzle. The melting point is higher than that of the sealant layer.

  Further, the manufacturing method of the packaging bag of the present invention has a winding mode in which any of the above-described packaging bags is formed by previously aligning a plurality of liquid dispensing nozzles bordered by a tearing guide rod. The nozzle film is fed out to the continuously running packaging film, and the base end of each liquid dispensing nozzle is sealed with the sealant layer on one outer surface of the dispensing nozzle. Heat seal to the surface sealant layer to bond the liquid pouring nozzle to the packaging film, and remove and remove the unnecessary part of the nozzle film from the liquid pouring nozzle along the tear guide rod. The intermediate seal portion corresponding to the joining position of the liquid pouring nozzle on the inner surface of the sheet of packaging film and that of one or two side free end portions of the packaging film In addition, a vertical seal that contributes to the section of the filling portion and the lid portion is applied, and then, in the running direction of the packaging film, at each predetermined position on the front side and the rear side from the joint portion of the liquid dispensing nozzle, In addition to applying each horizontal seal for hermetically forming the lid, a horizontal seal for sealing one side of the filling portion is provided. In this packaging bag, the other side of the filling portion is used for filling the package. Opening.

  In addition, the method for filling and packing a packaged object according to the present invention for any of the above-described packaging bags is formed by previously aligning a plurality of liquid dispensing nozzles bordered by a tearing guide rod. The nozzle film of the aspect is fed and run with respect to the packaging film that is continuously fed and run, and the base end portion of each liquid dispensing nozzle is a sealant layer on one outer surface of the dispensing nozzle, Heat seal to the sealant layer on the inner surface of the packaging film to bond the liquid dispensing nozzle to the packaging film, and separate and remove unnecessary portions of the nozzle film from the liquid dispensing nozzle along the tearing guide rivets. Each of the intermediate seal portion corresponding to the joining position of the liquid pouring nozzle on the inner surface of one or two packaging films and the side free end portion of the packaging film. In front of the entire width of the packaging film, which is formed in advance in the running direction of the packaging film in front of the joint portion of the liquid pouring nozzle while providing a vertical seal that contributes to the section of the filling portion and the lid portion Between the inner surface of the packaging film, between the lateral seal portion on the side and the lateral seal portion on the rear side formed over the entire width of the packaging film on the rear side from the joining position of the liquid pouring nozzle. Continuously supplying and forming a lateral seal portion on the rear side by sealing foreign matter such as by filling in the liquid, where the packaged object is sealed in the filling portion, and the lid The part, together with the liquid dispensing nozzle, is completely sealed against the outside air.

  In the packaging bag of the present invention, the liquid pouring nozzle made of the soft laminated film is sealed in the lid portion with the tip portion closed by fusion bonding of the sealant layer. The possibility that the surface may be soiled by dust, fungi, etc. outside the bag can be sufficiently removed, and the liquid pouring nozzle made of a soft laminated film can be removed by tearing the tip of the liquid pouring nozzle through a tearing means. When it is contained in the bag, a soft touch can be brought about, so that the in-bag package can be drunk sufficiently hygienically and safely.

  In addition, in this packaging bag, the tip of the liquid dispensing nozzle that is fusion-bonded to the intermediate seal portion and communicated with the filling portion is closed by the fusion-bonding of the sealant layer. Even if the filled and packed packaging bag may fall down, the packaged material in the bag will not flow into the lid, so the packaged material in the bag will adhere to the inner surface of the lid and the outer surface of the dispensing nozzle. Therefore, when opening the package by tearing and removing the lid at the tearing device position, it is possible to reliably prevent unintentional dripping of the package in the bag regardless of the storage posture of the packaging bag, etc. In addition, the tip of the liquid dispensing nozzle is torn and removed at the tearing means to form a nozzle opening, and the discomfort of touch when the liquid dispensing nozzle functions as a drinking mouth Can be completely removed That.

In addition, since the packaged items in the bag do not flow into the lid part here, the fungi on the inner surface of the lid part and the outer surface of the dispensing nozzle are sufficiently propagated regardless of the storage conditions of the packaging bag. In this way, the outer surface of the liquid dispensing nozzle can always be kept hygienic.
In addition, the liquid dispensing nozzle here can literally function as a nozzle for dispensing according to the requirements of the package in the bag under the formation of the nozzle opening.

  In such a packaging bag, the liquid pouring nozzle is removed after the pouring of the article to be packaged from the nozzle opening formed by tearing and removing the protruding tip of the liquid pouring nozzle into the lid at the forming portion of the tearing means. Self-sealing check function as disclosed in JP-A-2005-15029, JP-A-2005-59958, etc., in which the inner surface closely adheres to the packaged object under the presence of a thin film due to capillary action or the like In order to make the nozzle function as a pouring nozzle, the liquid pouring nozzle is used to form a liquid bag package under the condition that the packaging bag body made of a packaging film is a soft material. From the crushed deformation of the packaging bag body, etc., because it can be poured out as needed without sucking the outside air, oxidation of the packaged items in the bag due to the inflow of outside air into the packaging bag, Contamination It can be removed sufficiently.

  On the other hand, when stopping the dispensing of the package in the bag, as soon as the packaging bag is returned to the standing posture, the inner surface of the liquid dispensing nozzle is placed under the thin film of the package in the bag. Since it closely adheres and blocks the entry of outside air, the freshness, quality, etc. of the packaged items in the bag can be maintained as they are for a long period of time.

  Also, here, when the melting point of the sealant layer on the opposite inner surface side of the laminated film on each side of the front and back constituting the liquid pouring nozzle is higher than the outermost sealant layer of the liquid pouring nozzle, , Unintentional fusion bonding between the inner surfaces of the liquid dispensing nozzles when heat sealing the base end of the liquid dispensing nozzle to a location corresponding to the intermediate seal portion of the packaging film as described later Further, it is possible to sufficiently prevent the release paper or the like inside the liquid pouring nozzle or the like from being inserted and arranged in advance.

  And the manufacturing method of the packaging bag according to the present invention is formed by aligning a large number of liquid pouring nozzles that are preliminarily trimmed with tearing guides made of weak lines such as perforations and grooves. Nozzle film as disclosed in Japanese Patent No. 55739 is made to run and run under a speed control, for example, on a soft packaging film continuously running at a constant speed, most of which is a packaging film having a required laminated structure. The base end of each liquid pouring nozzle is a relatively low-melting sealant layer on one outer surface of the pouring nozzle while traveling at a constant speed with the packaging film. For example, the liquid pouring nozzle is bonded to the packaging film by heat sealing to a sealant layer made of the same material as the sealant layer on the inner surface. The intermediate seal portion which is separated from the liquid dispensing nozzle along the tearing guide rod and then removed, and then located on the inner surface of one or two packaging films corresponding to the bonding position of the liquid dispensing nozzle A vertical seal that contributes to the section of the filling part and the cover part is applied to each of the part and the side free end part of the part of the packaging film, and then, in the running direction of the packaging film, A lateral seal for sealingly forming the lid portion is applied to each of predetermined positions on the front side and the rear side from the joint portion of the liquid pouring nozzle, and a lateral seal for sealing one side of the filling portion is applied. The other side of the filling portion is to produce a packaging bag having a filling opening for the object to be packaged. According to this method, the packaging bag can be produced simply and quickly as expected. , Made Packing bag the functions mentioned above to be able to exhibit the intended the street.

  And in the filling and packaging method of an object to be packaged of this invention, for example, using an automatic filling and packaging machine, in particular, corresponding to the bonding position of the liquid dispensing nozzle on the inner surface of one or two packaging films. A vertical seal that contributes to the compartment of the filling portion and the lid portion is applied to each of the intermediate seal portion portion and one or two side free end portions of the one or two packaging films. However, in the running direction of the packaging film, the front side seal over the entire width of the packaging film and the rear side from the junction position of the liquid ejection nozzle, which is formed in front of the junction of the liquid ejection nozzle. The packaged article is continuously supplied between the inner surfaces of one or two wrapping films that are half-folded with the rear side sea part formed over the entire width of the wrapping film. Under deflation By forming the lateral seal portion on the rear side with the miscellaneous seal, a packaging bag filled and packaged to be packaged for pouring or drinking is also manufactured simply, quickly and as expected. be able to.

It is a top view which shows embodiment of the packaging bag of this invention in the filling packaging state of a to-be-packaged item. It is a cross-sectional view which follows the II-II line | wire of FIG. 1 which shows the film lamination structure of a liquid extraction nozzle. It is a top view similar to FIG. 1 which shows the other embodiment of this invention. It is a perspective view which illustrates the joining process of the liquid extraction nozzle to the packaging film. It is a top view which shows the example of a manufacturing process of the packaging bag which concerns on this invention.

The filling packaging bag 1 shown in FIG. 1 showing a state in which a jelly as an example of a liquid package is filled and packaged is a half-folded state of a single packaging film 2 made of a soft laminated film, and a sealant layer on the inner surface. As shown by hatching in the drawing, the vertical seal portion 3 made of heat seal at the free end portion and the horizontal seal portions 4, 5 made of upper and lower heat seal portions extending over the entire width of the packaging film 2. Thus, the inside of such a packaging bag 1 is filled and packaged by an intermediate seal portion 6 as shown in FIG. The filling portion 7 is divided into a tearing means 8 which will be described later, and a lid portion 9 which is torn and removed at the formation position of the tearing means 8 composed of perforated alignment holes in the figure. is there.
Such a filling and packaging bag can be constructed by sealing the sealant layer on the inner surface of two packaging films in four directions, and in the figure, the bag bottom located at the left end is a gusset having a folding structure. It can also be a bag.

For such a packaging bag 1, here, the sealant layer on the opposite inner surface of one half-fold laminated film or two laminated films is fused to each other by heat sealing at the peripheral portion excluding the base end side. The base end portion 10a of the liquid pouring nozzle 10 thus formed is fused and joined between the seal surfaces of the intermediate seal portion 6 with the outermost sealant layer, and the liquid pouring nozzle 10 is brought into the lid portion 9 inside. While arrange | positioning with a protrusion attitude | position, the inside of this extraction nozzle 10 is connected with the inner side of the filling part 7. FIG.
FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1, illustrating the film lamination structure of the liquid pouring nozzle 10 thus fused and joined to the intermediate seal portion 6. Is the periphery excluding the base side of the sealant layers 14 and 15 on the opposite inner surface of one or two laminated films 12 and 13 having a half-fold structure located on the front and back sides. Each of the liquid dispensing nozzles 10 constructed in this manner is formed by fusion-bonding with each other, and the base end portion 10a is disposed between the opposed seal surfaces of the intermediate seal portion 6 in the outermost layer. By fusion-bonding with the sealant layers 16, 17, the intermediate seal portion 6 is fusion-bonded in a posture protruding to the inside of the lid portion 9.

As shown in FIG. 2, the laminated films 12 and 13 on the front and back sides are each a single base film layer 18 and 19 made of, for example, a stretched film. Although the layers 14, 15 and 16, 17 are laminated, an appropriate vapor deposition layer or the like can be provided on the base film layers 18, 19 depending on the required physical properties, and the base film layers 18, 19 and An intermediate layer can also be provided between at least one sealant layer 14, 15 and 16, 17.
Further, in the figure, the melting point of the sealant layers 14 and 15 on the opposing inner surface is preferably higher than that of the outermost sealant layers 16 and 17 of the liquid pouring nozzle 10, When heat-sealing the sealant layers 16 and 17 on the outer surface of the base end portion of the liquid pouring nozzle 10 to the opposing seal surface of the intermediate seal portion 6, a release material or other fusion is bonded between the sealant layers on the inner surface of the pouring nozzle. It is not necessary to intervene a prevention member, and the base end portion of the dispensing nozzle 10 is surely fused as expected to the intermediate seal portion 6 without fear of unintentional fusion bonding between the inner surfaces of the nozzles. Can do.

In the place shown in FIG. 1 again, tearing means 8 and 20 are provided at each of the lid portion 9 and the leading end portion of the liquid dispensing nozzle 10 protruding into the lid portion 9, and the tearing means 20 of the liquid dispensing nozzle 10 is provided. The lid portion 9 is positioned farther from the filling portion 7 than the tearing means 8.
According to this, when each of the lid portion 9 and the dispensing nozzle 10 is torn and removed at the position of the tearing means 8 and 20, the nozzle opening 10b formed in the liquid dispensing nozzle 10 is projected forward. Therefore, the nozzle opening 10b can reliably function as both a drinking mouth and a spout.

In FIG. 1, the tearing means 8 of the lid 9 is formed only by a perforated hole, but the perforated hole and the − or V-shaped notch The tearing means 8 can also be formed by means of, and instead of perforated holes, the tearing means 8 is formed in the base film layer or the like by dot-like or continuous grooves formed by laser processing or the like. You can also.
Further, the lid tearing means 8 shown in the figure is arranged so that the tear removal of the lid 9 can be smoothly advanced without being affected by the presence of the liquid dispensing nozzle 10, and the nozzle 10 is overlapped with the liquid dispensing nozzle 10. Although it is formed in a triangular mountain shape that protrudes toward the distal end side, the mountain shape may be a curved convex shape, or may be a straight line shape without the mountain shape.

  1, the tearing means 20 of the liquid dispensing nozzle 10 is formed with V-shaped notches provided on both sides of the nozzle 10, but the shape of the notches may be −. The tearing means 20 can also be formed by dot-like or continuous grooves provided in the base film layers 18, 19 or the like, or by a combination of such grooves and any notch.

In the packaging bag 1 configured as described above, the peripheral portion of the liquid dispensing nozzle 10 excluding the base end side is completely fusion-bonded by heat sealing, and the interior of the liquid dispensing nozzle 10 is Although the intermediate seal portion 6 communicates with the inside of the filling portion 7 through the intermediate seal portion 6, the intermediate seal portion 6 partitions the filling portion 7 and the lid portion 9 in a liquid-tight and air-tight manner. Even if the bag is laid down, the bag-in-pack item in the filling portion 7 does not flow into the lid portion 9 or the like.
For this reason, there is no possibility that the in-bag packaging material adheres to the inner surface of the lid portion 9, the outer surface of the dispensing nozzle 10, etc. due to the flow of the in-bag packaging material in the filling portion 7.

Therefore, even when the lid 9 is removed by tearing at the position of the tearing means 8 as shown in FIG. 1 (b), the lid 9 is caused by unintentional dripping of the packaged material entering the lid 9 or the like. In addition, as shown in FIG. 1 (c), the tip portion of the liquid pouring nozzle 10 is torn and removed at the tearing means 20 position, and the pouring nozzle 10 is included in the mouth to wrap the bag. When drinking things, there is no discomfort that is uncomfortable to touch due to deposits on the outer surface of the nozzle.
Moreover, there is no joy of fungal growth in the lid and on the outer surface of the dispensing nozzle.

  By the way, the lid 9 is torn and removed, and the tip portion of the nozzle is also torn and removed to form the nozzle opening 10b as shown in FIG. Based on the tilting of the filling and packaging bag 1 or the like, it can be poured out through the nozzle opening 10b.

  FIG. 3 is a view showing another embodiment. This is a self-sealing check function as disclosed in Japanese Patent Application Laid-Open No. 2005-59958 for the liquid dispensing nozzle 10 of the filling packaging bag 1 shown in FIG. A liquid pouring nozzle having

The filling and packaging bag 1 shown in FIG. 3 tears and removes the lid portion 9 from the tearing means 8 and tears and removes the tip portion of the liquid dispensing nozzle 10 from the tearing means 20 as shown in FIG. In a state where the nozzle opening 10b is formed, the dispensing nozzle 10 can be used for drinking the packaged article in the bag, and can also be used for dispensing the packaged article in the bag from the nozzle opening 10b. In this latter case, by pressing the filling part 7 with fingers, or by placing the packaging bag 1 in a posture in which the nozzle opening 10b faces downward, Based on deformations such as crushing deformation and contraction deformation of the filling part 7, the outside air can be poured out without being sucked. By returning 1 to a standing position, etc. It is possible.
When stopping the pouring, the inner surfaces of the front and back surfaces of the liquid pouring nozzle 10 are immediately brought into close contact with each other under the thin film of the liquid packaged object to exhibit a self-seal check function. The entrance of the outside air into the part 7, and thus the possibility of oxidation of the in-bag packaging due to the outside air and the possibility of contamination by dust, fungi, etc. of the in-bag packaging can be sufficiently removed.

  And the manufacturing method of the packaging bag of this invention is related with the method of manufacturing the packaging bag by which the to-be-packaged goods are not filled and packaged, and is liquid first as shown in FIG. A wound nozzle film 31 formed by aligning a plurality of dispensing nozzles 10 in advance is continuously run at a constant speed, for example, for soft packaging film 2 having a laminated structure, under speed control. The base end portion of each liquid pouring nozzle 10 is moved at a constant speed with the packaging film 2 to a predetermined position of the packaging film 2 and one outer surface of the pouring nozzle 10. With the sealant layer having a relatively low melting point, for example, the inner surface of the intermediate portion in the width direction of the single packaging film 2, preferably a sealant layer made of the same material as the sealant layer And the liquid dispensing nozzle 10 is fused and joined to the packaging film 2, and the unnecessary portion 32 of the dispensing nozzle 10 is separated and removed from the liquid dispensing nozzle 10 along the tear guide rod, One or two wrapping films, in the figure one wrapping film 2 in a half-folded state, the seal located on the inner surface of the wrapping film 2 corresponding to the joining position of the liquid dispensing nozzle 10 The intermediate seal that contributes to the section of the filling portion 7 and the lid portion 9 shown in FIG. 1A by performing vertical heat sealing on each of the portion portion and the side free end portion of the half-folded packaging film 2 The part 6 and the vertical seal part 3 are formed.

Here, in the intermediate seal portion 6, the respective sealant layers on the opposed inner surface of the packaging film 2 are fusion-bonded to each other, and the respective sealant layers on the opposed inner surface are bonded to the outer surface of the liquid dispensing nozzle. Since each of the sealant layers having a relatively low melting point is fused and joined, the filling portion 7 and the lid portion 9 are reliably blocked by the intermediate seal portion 6 with the liquid pouring nozzle 10 interposed therebetween. It will be.
Further, in the vertical seal portion 3, the side free end portions of the half-folded packaging film 2 are sealed with each other by heat sealing of the opposing sealant layer, so that the outside air does not enter the lid portion 9. Therefore, the vertical seal portion 3 and the horizontal seal portion described later are reliably prevented.

FIG. 5 is a plan view illustrating a state in which one continuous long packaging film 2 is folded in half to form the intermediate seal portion 6 and the vertical seal portion 3 as described above. In the running direction of the packaging film 2 indicated by the white arrow, the lateral heat for sealingly forming the lid portion 9 at the front side and the rear side from the joint portion of the liquid pouring nozzle 10 is shown. Sealing is performed to form respective horizontal seal portions 4a and 5a as shown by phantom lines in FIG. 5, and under the cooperation of these horizontal seal portions 4a and 5a and the vertical seal portion 3, the lid portion 9 is moved. Shut off from outside air.
In addition, in the figure, in order to make the explanation easy to understand, it is assumed that the lateral seal portion 4a on the front side and the lateral seal portion 5a on the rear side are separately formed from the joint portion of the liquid pouring nozzle 10. However, both of the horizontal seal portions 4a and 5a can be formed as one wide horizontal seal portion, and in this case, a plurality of packaging bags formed continuously on the long packaging film 2 Is cut and separated into single packaging bags at the middle position of one horizontal seal portion, thereby revealing the respective horizontal seal portions 4a and 5a on the front side and the rear side.

Further, in combination with the formation of any one of the respective lateral seal portions 4a and 5a, either one side of the filling portion 7 is hermetically sealed. In the figure, the lateral seal portion 4b continuous to the lateral seal portion 4a. Is also formed.
Thereby, here, the horizontal seal portions 4a and 4b are integrated to form the horizontal seal portion 4 shown in FIGS.
According to this, for example, when a plurality of packaging bags continuously formed on the long packaging film 2 are cut and separated into bags one by one, the other side of the filling portion 7 is filled with the article to be packaged. It can be made to function as an opening for the above, and it fills with a to-be-packaged object from the opening, and makes it the filling packaging bag 1 as mentioned above, and makes the liquid extraction nozzle 10 function as mentioned above. be able to.

By the way, according to the present invention, the method of filling and packing a packaged bag with respect to a packaging bag is performed by using a liquid dispensing nozzle 10 for a long packaging film 2 that is continuously run as described with reference to FIG. After the one side is fused and joined, the packaging film 2 is half-folded, or the packaging film 2 and the inner surface sealant layer are opposed to the inner surface of the packaging film 2 The two sheets of the packaging film are passed through, for example, an automatic filling and packaging machine, and the intermediate sealing part 6 and the vertical sealing part 3 that become the longitudinal heat seal as illustrated in FIG. For the packaging film, for example, in addition to them, another vertical seal portion that is located on the left side of FIG. 5 and contributes to the section of the filling portion 7 is continuously provided over the entire length of the long packaging film. While forming into packaging packaging Position of the liquid pouring nozzle 10 in the traveling direction of the liquid, and the front side seal part, for example, the transverse seal part 4 and the entire width of the packaging film formed in front of the joint part of the liquid pouring nozzle 10 in advance. More to the rear side, the back side lateral seal portion formed over the entire width of the packaging film, for example, the lateral seal portion 5 is continuously supplied between the inner surfaces of the packaging film, The side seal portion 5 on the rear side is formed by sealing foreign matter such as by filling in the liquid. Here, the article to be packaged is enclosed in the filling portion 7 and the lid portion 9 is a liquid. Together with the dispensing nozzle 10, it is completely sealed against the outside air.
In this case as well, continuous packaging bags that are continuously manufactured with a long packaging film and are filled with an article to be packaged are cut and separated into individual bags, as shown in FIGS. Each individual filling and packaging bag 1 is used.

  When the individual filling and packaging bags 1 formed in this way are formed by half-folding a single packaging film 2, as shown in FIGS. When it is configured by two packaging films, the left end portion of the filling packaging bag 1 shown in FIGS. 1 and 3 is often used. This is a four-sided seal bag with a bottom vertical seal.

  Although not shown, when the portion corresponding to the bottom of the packaging bag is formed by fusion bonding of separate films, the packaging bag can be a self-supporting gusset bag or the like.
