Description

  The present invention relates to a packaging structure for a liquid-filled packaging body including a film-like dispensing nozzle that exhibits a self-sealing check function made of a soft laminated film.

  As a packaging bag provided with a film-like dispensing nozzle having a self-sealing check function, there are those disclosed in Patent Documents 1 and 2. The characteristic of the pouring nozzle used in this packaging bag is that when the liquid or viscous packaged material in the packaging bag is poured out, the outside air corresponding to the amount to be poured is replaced in the packaging bag. It is in the structure of the point that can be prevented from entering.

  That is, the packaging bag itself shrinks or collapses as the packaged material in the bag is poured out. A non-return function for preventing intrusion of outside air or the like into the packaging bag is exhibited by bringing the inner surfaces of the dispensing passages of the nozzles into close contact with each other.

  Therefore, the higher the flatness (flatness) of the film-like pouring nozzle, the stronger the adhesion between the inner surfaces of the pouring passages under the intervention of the thin liquid film of the packaged object, and further the check function. It can be said that it will be useful for improvement.

  The packaging bags described in Patent Document 1 and Patent Document 2 are both soft in order to effectively exhibit the above-described check function of the film-like dispensing nozzle. It is comprised by the laminated film of. Therefore, when using the packaging bag, it is necessary to hold the liquid-filled package filled with the packaged item in an outer container made of paper or resin.

  Therefore, the inventor examined the replacement of the liquid-filled packaging body and the reuse of the outer container from the viewpoint of environment and economy, but the liquid-filled packaging body is a soft laminate as described above. Since it is formed of a film, there is a problem that it is easy to break the bag due to shaking or impact during distribution. Moreover, since the film-like dispensing nozzle is provided in a state protruding from the packaging bag body, the nozzle portion may be bent and deformed at the time of distribution, which may lead to the deterioration of the check function described above. It was.

  Furthermore, when the package filled with liquid material is distributed, the load of the packaged material is concentrated on the film-like dispensing nozzle, the seal part is broken, or the poured channel is swelled and deformed by the packaged material that has flown In particular, when the article to be packaged is in a heated state (50 to 100 ° C.) for the purpose of sterilization or the like, the pouring passage is heated by the article to be packaged and the head of the article to be packaged Under pressure, it may be plastically deformed by swelling or the like, and the close contact between the inner surfaces of the dispensing passage may be hindered, and the self-seal check function may not be effectively exhibited.

  Therefore, in view of the above-mentioned problems of the prior art, the object of the present invention is to distribute a liquid-filled package in a state filled with a liquid or viscous packaged object separately from the outer container. Can reliably prevent the possibility of bag breakage due to impact at that time, in particular, bends and deforms the film pouring nozzle, and inhibits the self-seal check function. An object of the present invention is to provide a packaging structure for a liquid-filled packaging body having no liquid.

  The present invention has been developed through intensive research and studies to achieve the above object. The gist of the present invention is a packaging bag body made of plastic film and the upper corner of the packaging bag body. A packaging structure for a liquid-filled packaging body in which a liquid or viscous packaged article is filled in a packaging bag composed of a film-like dispensing nozzle having a self-sealing function protruding from the top or the top. On the plate-shaped substrate, one or more liquid-filled packaging bodies are placed, and the film-like dispensing nozzle is sandwiched via a pressing member, while at least the liquid-filled packaging body A packaging structure for a liquid-filled packaging body is proposed in which the packaging bag body is surrounded and fixed by a packaging material.

Is preferred.

  According to the packaging structure for a liquid filling packaging body of the present invention, the liquid filling packaging body is placed on a plate-like base material, and in that state, a packaging material made of a plastic film or the like is wound, Since it can be fixed, there will be no misalignment during transportation. Moreover, since the film-like dispensing nozzle protruding from the upper corner or top of the liquid-filled package body is pressed and fixed by the pressing member, the film-like dispensing nozzle is protected from various impacts during distribution. It is possible to prevent the film-like dispensing nozzle from being bent, deformed or damaged. Furthermore, since the inflow of the article to be packaged into the pouring passage of the film-like pouring nozzle can be prevented, there is no risk of deformation to the full state, and the non-return function of the film-like pouring nozzle is provided. There is no hindrance.

It is a figure which shows one Embodiment of a liquid filling package. It is a figure which shows an example of the outer container which accommodates and hold | maintains a liquid filling package. It is (a) top view and (b) sectional view showing one embodiment of the packing structure for liquid filling packing bodies concerning the present invention. It is the (a) top view and (b) sectional view which show other embodiment of the packing structure of the liquid filling packaging body which concerns on this invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
First, the liquid filling package will be described. The liquid-filled package 1 in FIG. 1 is placed in a packaging bag comprising a packaging bag body 2 made of a plastic film, and a film-like dispensing nozzle 3 communicating with the packaging bag body 2 and having a self-seal check function. Filled with a liquid or viscous package (hereinafter simply referred to as “liquid package”). Note that the film-like dispensing nozzle 3 has an outermost sealant layer at the base end thereof in a posture projecting obliquely upward in the figure to the sealant layer on the inner surface of the upper end portion of the packaging bag body 2, for example, by fusion bonding By doing so, it is integrated with the packaging bag body 2.

  Here, the film-like dispensing nozzle 3 is laminated with a thermoplastic stretched base film layer, for example, a uniaxial or biaxially stretched PET layer or NY layer having a thickness of 5 to 40 μm, and the stretched base film layer interposed therebetween. Each sealant layer, for example, an unstretched PE layer or PP layer having a thickness of 5 to 80 μm, and each of the thin laminated films on the front and back sides having a three-layer structure, that is, two front and back sheets having the same contour shape A thin laminated film or a single thin laminated film folded back and forth at the center, etc., is melted together, for example, by heat sealing, in the peripheral part of one sealant layer facing each other and excluding the base end. The pouring passage 4 is defined in the center portion by being bonded and bonded. That is, in the illustrated film-like dispensing nozzle 3, the nozzle tip portion 5 is cut off by, for example, tearing removal at the position of the V-shaped bent portion 6 to form the tip opening 7 in the dispensing passage 4. It will be.

  On the other hand, the packaging bag body 2 is composed of a soft laminated plastic film including a uniaxial or biaxially stretched base film layer and a sealant layer laminated on one side surface of the base film layer, for example, via an intermediate layer, In the figure, the sealant layers are opposed to each other, and in the figure, they are folded back to the front and back at the central portion, and the peripheral portion can be formed by fusion bonding by, for example, heat sealing.

  For such a liquid-filled package 1, when the liquid package is poured, the tip portion 5 of the film-like dispensing nozzle 3 is torn and removed as described above, and the film-like dispensing nozzle 3 is poured. In a state where the tip opening 7 is formed in the passage 4, the liquid filling package 1 is tilted, and the tip opening 7 is opened by greatly separating the inner surfaces of the pouring passage 4 by the head pressure of the liquid package. By doing so, the liquid package can be dispensed as required. At this time, the packaging bag body 2 contracts or collapses according to the liquid volume to be packaged, and this prevents any outside air from being taken into the liquid-filled package 1. The packaged item can be poured out under the stopping action.

  On the other hand, stopping the pouring of the liquid package causes the liquid-filled package body 1 to stand up and return, and simultaneously with the stand-up return, the pouring passage 4 opens from the head pressure of the liquid package. Is possible. That is, the packaging bag main body 2 has the inner surface wetted by the thin film of the liquid package in addition to the crushing deformation caused by the negative pressure generated by the discharge from the package bag main body 2. A negative pressure adsorption state is established under the assistance of a reduced-pressure atmosphere in the packaging bag body 2. As a result, the dispensing passage 4 is automatically hermetically sealed, and a self-seal check function for preventing the entry of outside air into the liquid-filled package 1 is automatically exhibited. become.

  Therefore, the liquid-filled package 1 is sufficiently protected from contact with the outside air both during and after pouring, as well as before the liquid package is poured. Oxidation, fouling, etc. of the liquid package are effectively prevented.

  In addition, when the film-like dispensing nozzle 3 is projected obliquely upward from the upper corner or top of the packaging bag body 2 as shown in FIG. At the same time as the force (transmission force) in the direction along the tip opening 7 of the discharged liquid packaged object is reduced, the packaged object in the dispensing passage 4 is drawn into the packaging bag body 2. The negative pressure of will act more. As a result, the liquid-discharging property when the liquid-filled package 1 is raised and returned to stop the dispensing of the packaged item and the packaged item is improved, and at the same time, the film-like dispensing nozzle 3 There is no possibility that an object to be packaged adheres and remains in the front end opening 7, and it is possible to effectively eliminate the occurrence of dripping and the possibility of contamination of the liquid-filled package 1 and its surroundings.

  It is very important for such a liquid-filled package 1 to ensure the long-term non-return function of the film-type non-return nozzle 3, especially in the transportation process of goods. Become. In particular, the packaging bag body 2 is made of a soft plastic film, and has no self-supporting property or formability. Therefore, when the liquid packaged material is poured out (discharged) from the film-like dispensing nozzle 3. The liquid-filled package 1 is preferably made of paper or plastic, for example, held in an outer container 8 as shown in FIG. .

  In addition, the outer container 8 shown in FIG. 2 is a rock that enables opening and closing of the dispensing passage 4 of the film-like dispensing nozzle 3 at a position corresponding to the film-like dispensing nozzle 3 of the liquid filling package 1 to be stored. The swing opening / closing lid 11 has a movable opening / closing lid 11 and is pivotally connected to one end of the holding clip 9 via a hinge 10 (pin). Therefore, according to the outer container 8, the liquid filling package 1 can be easily replaced simply by attaching and removing the holding clip 9 to the upper end of the plate-like part 8a at the upper part of the outer container main body.

  When the outer container 8 as shown in FIG. 2 is used, the outer container 8 itself can be used repeatedly. Therefore, it is necessary to distribute the liquid-filled package 1 alone. However, as shown in FIG. 1, the film-like dispensing nozzle 3 of the liquid-filled package 1 is projected from the upper corner or top of the packaging bag body 2, so that it remains as it is during transportation. If it is stored in the body or bag, the film-like dispensing nozzle 3 may be torn or misopened due to an impact during transportation. Further, when the film-like dispensing nozzle 3 is bent and deformed, it is impossible to discharge the liquid package in the intended direction, or the liquid dispensing nozzle 4 has a liquid covering the dispensing passage 4. When the package has been filled (inflowed) for a long time, the film-like dispensing nozzle 3 is in a state of plastic deformation, and as a result, the adhesion between the films due to the surface tension due to the liquid package is obstructed. Such a self-sealing function may be hindered.

Therefore, it was developed for the purpose of reducing impact during distribution of the liquid-filled package 1 and preventing deformation of the dispensing passage 4 due to bending or erroneous opening of the film-like dispensing nozzle 3 or plastic deformation of the film. One embodiment of the packaging structure for a liquid-filled package 1 according to the present invention is shown in FIG.
In this packaging structure, two liquid-filled packaging bodies 1 are placed side by side on the plate-like base material 13 in the figure, and a sectional view taken along the line AA in FIG. 3A (FIG. 3B). ), The film-like pouring nozzle 3 protruding from the top is pressed from above by a pressing member 14 made of a strip-shaped plate material, and in this state, the outer periphery of the liquid filling package 1 and the base material 13 In addition, the packaging material 15 made of, for example, a plastic film is wrapped and surrounded so that the liquid-filled packaging body 1 is firmly fixed on the plate-like base material 13.

  As described above, in the liquid-filled package 1, the film-like pouring nozzle 3 portion is fixed on the base material 13 by pressing by the pressing member 14, and at least the packaging bag main body 2 portion is surrounded and fixed by the packing material 15. Therefore, the position does not shift during transportation or the like, and particularly when the packaging material 15 is made of a plastic film, the adhesiveness to the packaging bag body 2 made of the plastic film is also good, and the position shift is more effective. Can be prevented.

  According to such a packing structure, even if a plurality of liquid-filled packaging bodies 1 are arranged and packed, there is no risk of misalignment, bag breakage due to contact between the liquid-filled packaging bodies 1 or erroneous opening, Moreover, since a plurality can be distributed together, the unit price of the liquid filling package 1 is reduced, and an improvement in economic efficiency can be expected.

  The base material 13 may be cardboard, corrugated cardboard, hard plastic, wood, metal thin plate, or a composite material thereof. The base material 13 is folded in a state in which the liquid-filled package 1 is placed on the packing structure. It only needs to be strong enough not to bend. Further, as the packing material 15, various soft plastic films (including laminated films), rubber, cloth, and the like can be used.

  Further, the pressing member 14 may be formed using the same material as the base material 13, and for example, cardboard, cardboard, hard plastic, wood, a thin metal plate, a composite material of these, or the like can be used. Further, the pressing member 14 may have any shape as long as it can horizontally press the film-like pouring nozzle 3 portion. For example, each holding member 14 or a plurality of liquid substances A band-shaped plate material that can press the film-like dispensing nozzle 3 of the filling package 1 at a time, a clamping clip, or the like can be used.

  Therefore, according to the packing structure of FIG. 3, the film-like dispensing nozzle 3 is protected by the presser member 14 even when an impact or load is applied to the liquid-filled package 1 during transportation or storage. Therefore, there is no fear of bending, deformation, unsealing, and the like, and further, the holding member 14 allows the liquid-like packaged material to be fed to the dispensing passage 4 of the film-like dispensing nozzle 3 communicating with the packaging bag body 2. Since the inflow can be prevented, the load of the liquid package is concentrated on the pouring passage 4 and the seal portion is broken, or the pouring passage 4 is swelled and deformed by the inflowing liquid packaging. The close contact between the inner surfaces of the outlet passage 4 is inhibited, and the self-sealing function of the film-like dispensing nozzle 3 is not inhibited.

  Next, another embodiment of the packaging structure of the liquid-filled package 1 is shown in FIG. In this packing structure, as shown in a cross-sectional view taken along the BB position in FIG. 4 (a) (FIG. 4 (b)), a strip-shaped pillow member 16 is provided on a base material 13 of a plate material, and the pillow member The film-like dispensing nozzle 3 of the liquid filling package 1 is placed on 16. According to this, since the position of the film-like dispensing nozzle 3 is increased by the height of the pillow member 16, the film-like dispensing nozzle 3 is moved upward by the presser member 4 compared to the case where there is no pillow member 16. The bending of the base end portion of the film-like dispensing nozzle 3 when pressed from above can be suppressed. The pillow member 16 can be formed of cardboard, cardboard, hard plastic, wood, a thin metal plate, a composite material thereof, or the like.
