Description

  The present invention relates to a packaging method for a liquid filling package comprising a liquid pouring nozzle with a non-return function made of a soft laminated film, and in particular, the liquid filling packaging is used during inspection or boxing operations or for transportation. The present invention proposes a method for packing a liquid-filled package that protects against impacts in the process, and is particularly effective to prevent deformation, breakage, misopening, and the like of the dispensing nozzle.

  Liquids such as soy sauce, liquid or viscous foods such as jelly, dressings that may contain granular materials, liquid seasonings, alcoholic beverages, oils and other liquids for packaging that can be poured repeatedly Usually contained in a container. Such packaging containers include those described in Patent Document 1 and Patent Document 2. The packaging container disclosed in these documents is composed of a packaging bag body made of a soft laminated film, and a liquid dispensing nozzle with a check function formed so as to protrude from the upper part or the top part of the packaging bag body. Has been. The characteristic of these packaging bags is that self-occurring due to the inside of the packaging bag being crushed and deformed to a negative pressure by the dispensing of the packaged goods performed through the liquid dispensing nozzle. The seal non-return function prevents the outside air from entering the main body of the packaging bag and keeps the freshness of the object to be packaged for a long time.

That is, according to such a packaging bag, there is no uptake of outside air into the packaging bag main body (intrusion of air due to backflow) due to the extraction of the packaged item, so oxidation of the packaged item in the bag, a decrease in flavor, The risk of contamination can be effectively removed. Moreover, the liquid dispensing nozzle with a non-return function allows the liquid dispensing when the dispensing is stopped by tilting the packaging bag and pouring out the article to be packaged, and then returning to the original standing posture. Since the nozzle tip (outlet) is in a hermetically sealed state, it is possible to reliably prevent the outside air from entering the bag from the nozzle, so there is an advantage that the packaged item can be kept fresh until the end. .

  In the packaging bags described in Patent Document 1 and Patent Document 2, both the liquid dispensing nozzle and the packaging bag body are composed of a soft laminated film in order to make use of the check function of the dispensing nozzle described above. ing. As such, it is neither self-supporting nor fixed. Therefore, in this packaging container, in use, it is necessary to hold a liquid-filled package filled with an article to be packaged through a holder H shown in FIG. 3 made of paper or resin. . In this case, since the liquid-filled packaging bag is distributed and sold separately from the holder H to be reused, it needs to be in a form suitable for transportation.

  However, as described above, in addition to the liquid pouring nozzle having to have a non-return function, this liquid-filled package body uses a thin and soft laminated film for volume reduction. Therefore, there is a problem that the bag is likely to be broken due to shaking or shock during distribution. Moreover, since the liquid dispensing nozzle is provided in a state of protruding from the packaging bag body, the nozzle part is bent and deformed during distribution, and there is a problem that the above-described check function is hindered. . Moreover, the load of the article to be packaged may be concentrated on the nozzle, the seal portion may be broken, or the tear notch provided in the dispensing nozzle may be broken, and the spout may be accidentally opened.

  Therefore, in the distribution of such replaceable liquid-filled packaging bodies, conventionally, it has been necessary to individually wrap the liquid-filled packaging bodies with a cushioning material or the like, which takes time and increases the cost. There was a problem.

  An object of the present invention is to solve such problems of the prior art, and the object of the present invention is to inspect and pack a liquid-filled package in a state filled with an article to be packaged. It is effective for holding in the outer bag so that the possibility of bag breakage due to impact during distribution or during distribution can be reliably prevented and the check function of the dispensing nozzle is not hindered. The object is to propose a method for packing a liquid-filled package.

In order to achieve the above object, the present invention provides a packaging bag body made of a soft laminated film, and a reverse made of the following soft laminated film provided so as to protrude from the side, corner, or top of the packaging bag body. a nozzle exit liquid Note having a stop function, in the packaging bag that consists of, per the packing liquid product filling packaging body formed by filling the object to be packaged in the liquid or viscous稠状, laminating the liquid product filling packaging an outer bag made of a film, after housing without folding the liquid pouring nozzle from an opening provided in the outer bag, evacuating the interior of the outer bag, then by sealing the opening and characterized in that the liquid product filling packaging body, in the figure of the state where the liquid pouring nozzle protruding sealed hermetically in the outer bag is fixed, to reinforce the nozzle pouring liquid by said outer pouch Packaging of liquid filling packaging Law proposes.
Record
In the liquid pouring nozzle, two soft laminated films of the same front and back with the same contour shape, or a single soft laminated film folded back on the front and back at the center, under the mutually facing posture of the inner surface side sealant layer The outer peripheral portion excluding the portion that becomes the base end side of the nozzle is fused to each other to form a discharge passage in the center portion, and the base end side portion is made of a soft laminated film The packaging bag body is provided on the inner surface of the upper side portion of the packaging bag by the outermost sealant layer so as to communicate with the inside of the body so as to communicate with the inside, and the packaging bag body is tilted. When the article to be packaged is discharged and the article to be packaged is discharged and passed, the facing inner surfaces that become wet in the discharge passages of the packaging bag body after the dispensing is stopped In a reduced-pressure atmosphere accompanying standing posture Has been, due to the packaged articles is retained in the nozzle inner surface exits the infusion, it refers to those which exhibit the non-return function of preventing the entry of outside air by close contact with each other.

In the present invention,
(1) The outer bag is composed of a laminated film comprising a uniaxial or biaxially stretched base film layer and a sealant layer, and the base film layer is composed of a polyethylene terephthalate film layer or a nylon resin film layer, while the sealant layer Consists of a polyethylene layer or a polypropylene layer,
(2) The outer bag is formed with an opening notch of any one of an I notch, a V notch, a U notch, a base notch and a diamond cut at one peripheral edge thereof,
Is a more preferable solution.

  In the packaging method according to the present invention, the liquid material filling package is stored in the outer bag and then degassed, and at the same time, the opening of the outer bag is heat-sealed, so that the liquid material is filled. The liquid-filled package body thus made can be held in a state of being firmly fixed in the outer bag. In addition, in this case, the dispensing nozzle is not bent and the essential self-seal check function is not impaired. That is, according to the present invention, the liquid-filled package can be sufficiently protected against various impacts during handling and distribution, and the liquid-filled package can be displaced. It is possible to prevent occurrence of pinholes, deformation and breakage of the dispensing nozzle, and erroneous opening.

  In particular, according to the present invention, when the liquid-filled package is accommodated in the outer bag, it is prone to project from the upper part of the side portion of the packaging bag body, so that it is susceptible to bending and deformation. The dispensing nozzle reliably prevents such a situation so that the check function does not hinder the protection of the package, that is, prevents oxidation and corrosion of the package such as soy sauce, It is effective to keep them fresh for a long time.

  Furthermore, according to the present invention, the liquid-filled package can be packaged easily and at low cost, and handling becomes easy.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
First, the liquid filling package will be described. FIG. 1 is a perspective view showing an example of a liquid-filled package body 10. In a packaging bag body 2 composed of a packaging bag body 2 made of a soft laminated film and a liquid dispensing nozzle 1 with a check function, for example, , A state in which liquid packages such as soy sauce, noodle soup, oil and wine are filled. In such a liquid-filled package 10, the packaging bag body 2 and the liquid dispensing nozzle 1 are formed of a soft laminated film having at least a base film layer and a sealant layer, and both of them are formed as an integral one, or Heat the proximal end portion of the pouring nozzle having a sealant layer, which can be, for example, an unstretched polyethylene layer or a polypropylene layer, on one side edge of the packaging bag body 2, preferably on the side upper portion, corner portion or top portion. They are manufactured in a continuous manner by fusion bonding using a seal, a high frequency seal, an impulse seal or the like. In the following, a case will be described in which a separate liquid pouring nozzle 1 is fusion-bonded and protruded from the packaging bag main body 2, but this can also be formed integrally with two front and back films. is there. In addition, the fusion | fusion part of the packaging bag main body 2 and the base end part of the liquid extraction nozzle 1 was shown as the oblique line with a big space | interval in drawing.

  First, the liquid pouring nozzle 1 is used, for example, at the side of the packaging bag body 2 at the time of filling / packaging of the article to be packaged in the packaging bag body 2 or prior to filling / packaging of the article to be packaged. The sealant layer on the outer surface of the base end portion of the liquid pouring nozzle 1 is bonded to the upper inner surface, preferably by heat sealing, so that the upper side portion, corner portion, or top portion of the packaging bag body 2 is joined. It is provided in the state which protruded from.

  That is, this liquid pouring nozzle has two front and back soft laminated films having the same contour shape, or a single laminated film folded back on the front and back at the center, with the inner surface side sealant layer facing each other. Thus, each side portion excluding the base end side is fused to each other to form a discharge passage in the central portion. And in relation to the packaging bag body 2, the base end side portion of the liquid pouring nozzle 1 is formed on the inner surface of the upper side portion of the packaging bag body made of a soft laminated film by the outermost sealant layer. The projection is provided by fusion bonding so as to communicate with the inside of the main body. According to such a configuration, when the packaging bag body is tilted to discharge the packaged object, the facing inner surfaces that become wet in the discharge passage when the packaged object is discharged and passed are It is exposed to the reduced pressure atmosphere accompanying the standing posture of the packaging bag body after stopping the pouring, and the objects to be packaged adhere to each other by causing a capillary phenomenon on the inner surface of the nozzle. A self-seal check function that prevents outside air from entering occurs.

  In order to prevent mutual fusion of the sealant layer 5 on the inner surface of the nozzle in such fusion bonding of the outer surface of the base end portion of the liquid dispensing nozzle 1 to the packaging bag body 2, This can be solved by using films having different melting points for the sealant layers 5 and 6.

  Moreover, it is preferable to use the same kind of resin material for the sealant layer 6 constituting the outer surface of the liquid pouring nozzle 1 and the sealant layer 5 constituting the inner surface of the packaging bag body 2. According to this, the fusion-bonding strength between the liquid pouring nozzle 1 and the packaging bag body 2 can be sufficiently increased. Among them, the polyethylene layer and the polypropylene layer can exhibit excellent sealing strength at a relatively low heat sealing temperature, so that the base end of the liquid pouring nozzle can be easily, quickly and reliably packaged. It can be fusion bonded to the body.

  On the other hand, the packaging bag main body 2 becomes a liquid-filled package body 10 having a full form as shown in FIG. In this liquid filling package 10, the packaging bag body 2 is formed of a soft laminated film, and itself is neither self-supporting nor fixed, so that the content is poured out from the liquid pouring nozzle 1. When discharging (discharging), the liquid-filled package 10 is housed in a holding container (holder H) made of paper or plastic as shown in FIG. It is preferable to provide.

  When the packaged material filled in the liquid-filled package 10 is poured out from the liquid pouring nozzle 1, the liquid pouring nozzle 1 is shown in FIG. The tip portion of the liquid pouring nozzle 1 is opened by tearing it away with, for example, a finger from the notch portion 3 provided at an appropriate position, and then the liquid filling package 10 is preferably stored and held therein. Tilt together with holding container H. By such an operation, the tip spout of the liquid dispensing nozzle 1 of the liquid-filled package 10 is sufficiently opened to the front and back sides by the water head pressure of the packaged item in the bag, and the contents as required The item (packaged item) will be dispensed.

  As described above, the liquid filling and packaging body 10 has the liquid pouring nozzle 1 protruding from the corner or side upper part of the packaging bag body 2, so that it can be used as it is during transportation or the like. When the container is stored in the container, the liquid dispensing nozzle 1 is torn or bent and deformed due to an impact during transportation. Then, at the time of pouring, due to the deformed portion of the liquid pouring nozzle, the adhesion based on the capillary phenomenon through the liquid material of the front and back films is lost, and the self-seal check function is only hindered. However, there may be cases where it cannot be poured out in the intended direction. Further, since the liquid dispensing nozzle 1 is configured so that it can be easily opened with fingers, there is a possibility that the liquid dispensing nozzle 1 may be opened by mistake when performing other operations during handling.

  Therefore, in the present invention, as shown in FIG. 2, in order to reduce impact during handling and transportation, and to prevent the liquid pouring nozzle 1 from being bent and further erroneously opened, After being accommodated in the outer bag 20 made of a soft laminated film, the inside of the outer bag 20 is degassed, and then heat sealed, and if possible, vacuum shrink-wrapped, and the liquid-filled package 10 is placed in the outer bag 20. Propose a fixed and fixed packaging method. In addition, the holes 7 and 8 provided in the illustrated bag upper part (lateral heat seal part) are for suspending and holding the bag in the holder.

  By adopting such a packing method, the liquid-filled package 10 is placed in a state protected by the outer bag 20 while maintaining the entire shape including the liquid pouring nozzle 1 in its original form. Moreover, the occurrence of broken bags, pinholes, and the like, and the liquid pouring nozzle 1 is not bent and deformed due to an impact during transportation. Moreover, since the liquid filling package 10 is held in a state of being fixed in the outer bag 20, the liquid dispensing nozzle 1 is not deformed or the notch portion 3 is not torn during distribution. Further, the seal portions 4, 5, 6 of the liquid dispensing nozzle 1 are reinforced by the outer bag 20. Therefore, even if the impact at the time of conveyance and the load of the article to be packaged are concentrated on the liquid dispensing nozzle 1, the seal portions 4, 5, and 6 are not easily broken. Moreover, the liquid-filled package 10 is easy to handle, and can be transported without problems even if a plurality of the packages are stacked and stored in a cardboard box or the like.

  The outer bag 20 is formed of a laminated film including a uniaxial or biaxially stretched base film layer and a sealant layer, and an intermediate layer may be provided between the base film layer and the sealant layer as necessary. This laminated film is formed by laminating a base film layer and a sealant layer (including those having intervening intermediate layers if necessary) by, for example, extrusion lamination or dry lamination.

The base film layer for the outer bag 20 is preferably made of a polyethylene terephthalate film layer or a nylon resin film layer, and the sealant layer is preferably made of a polyethylene layer or a polypropylene layer. The thickness of these films, base Sufirumu layer 10 to 50 [mu] m, it is preferable that the sealant layer is 40 to 60 [mu] m. In particular, the biaxially stretched polyethylene terephthalate film layer uses “Emblet PC” (registered trademark), which is a linearly cut polyester film. It is recommended to use the film “Emblem NC” (registered trademark). The reason for this is that, according to these films, as compared to the case of using a uniaxially stretched base film layer, as will be described later, when the outer bag 20 is torn and opened from the opening bag 30 with fingers, the opening portion is linear. This is because it is possible to smoothly and easily remove the tear, and to make the tear wrinkle sufficiently smooth without fuzzing or the like.

The outer bag 20 is used to pack the liquid-filled package 10 under reduced pressure (including vacuum) and hermetically seal it. When shrink-wrapping, for example, polyvinyl chloride, polypropylene, etc. It is effective to use a heat-shrinkable plastic film such as polyethylene, polystyrene, polyethylene terephthalate or polyolefin.

  And this outer bag 20 is folded in two so that the sealant layer is on the inner side of the laminated film made of such a film, and heat-seal the side edge and the lower edge, or two laminated films, It is formed in a bag shape by heat sealing the both side edges and the bottom edge so that the sealant layer is inside.

  An opening bag 30 such as an I notch, a V notch, a U notch, a base notch, and a diamond cut is preferably formed on one peripheral edge of the outer bag 20. Thereby, the outer bag 20 can be easily opened with fingers, and the liquid-filled package 10 can be easily taken out from the outer bag 20.

  The opening trough 30 is formed on one peripheral edge of the outer bag 20, that is, on any one of the heat seal portions of the vertical heat seal portions on both side ends and the horizontal heat seal portions on the upper and lower ends. When tearing, it is preferable that the cut end be provided at a position where it does not intersect with the liquid filling package 10 inside the outer bag 20.

  The opening of the outer bag 20 is performed by tearing the opening bag 30, and a large number of fine perforations or scars are provided in the region of the outer peripheral edge of the outer bag 20 to be the opening position. It may be opened by tearing with fingers. The perforations or scars may be provided in at least one layer of the laminated film constituting the outer bag 20, and it is preferable to print a mark or the like indicating the opening start position.

  Hereinafter, an example of a method for accommodating the liquid-filled package 10 in the outer bag 20 and packaging under reduced pressure will be described. First, as shown in FIG. 4, the liquid filling and packaging body 10 is accommodated from an opening 21 provided at, for example, the upper end of the outer bag 20. Next, the opening 21 of the outer bag is heat-sealed leaving the suction tube port 23, and then the suction tube 22 is inserted into the suction tube port 23 to evacuate the inside of the outer bag 20. As a result, the outer bag 20 comes into close contact with the liquid-filled package 10 (nozzle type).

  After deaeration, the suction tube 22 is pulled out from the suction tube port 23, and the suction tube port 23 is sealed by heat sealing. As a result, the liquid-filled package 10 is vacuum-packed in the outer bag 20. In the deaerated state, since the inside of the outer bag 20 has a negative pressure, even if the suction pipe 22 is pulled out, air does not immediately flow into the outer bag 20.

  As a method for hermetically sealing the liquid-filled package 10 in the outer bag 20, in addition to the above, the liquid-filled package is packaged and enclosed in a vacuum (vacuum) type box having a heat sealer. It is possible to adopt a method (chamber type) or a method in which a liquid-filled package is shrink-wrapped with a heat-shrinkable plastic film and closely packed.

  The packaging method according to the present invention is particularly effective for a liquid-filled package having a check function, but can be applied to other liquid packages.

It is a perspective view which shows an example of a liquid filling package. It is a figure which shows the method of packing the liquid filling packaging body of this invention. It is a figure which shows the holder for hold | maintaining the other liquid filling package body of this invention. It is a figure which shows an example of the sealing method in the outer bag of a liquid filling package.
