Description

  The present invention is a film-type non-return pouring with a self-sealing non-return function that automatically prevents the outside air from entering the bag body, which is composed of two laminated soft plastic laminated films, front and back. A flexible, non-self-supporting liquid-filled packaging body in which a flexible packaging bag provided with a nozzle (liquid pouring nozzle) is filled with liquid materials such as beverages, liquid seasonings, cosmetics, and medicines, and the like The present invention relates to a liquid-filled packaging structure comprising an outer container made of hard plastic or paper for storing and holding a container.

  As the above-mentioned film-like non-return dispensing nozzle having a self-sealing non-return function made of a soft laminated plastic film and a flexible packaging bag having the same, those disclosed in Patent Documents 1 and 2 according to the proposals of the inventors There is.

  The non-return function of the film-like non-return dispensing nozzle disclosed in Patent Documents 1 and 2 is that the two laminated plastic films that are flat and in close contact with each other are overlapped and face each other, and those laminated plastic films that overlap each other Self-sealing check function that prevents the intrusion of outside air that tries to infiltrate after the contents are discharged, by the liquid material always interposing and closely contacting the dispensing passage formed between them by capillary action Is to demonstrate.

These film-like non-return pouring nozzles disclosed in Patent Documents 1 and 2 and flexible packaging bags provided with the same are filled with fluids such as soy sauce and other liquid seasonings and salad oil in a liquid seal ( The upper and lower ends of the packaging bag body are laterally sealed from above the filling liquid so that air, nitrogen gas, etc. are not mixed in), or the bag is degassed after filling the packaged material, so that the liquid is substantially liquid. It is used as a liquid-filled package that contains only the article to be packaged (filled in a gasless state). And when pouring out a liquid package from this liquid filling package, the package has the characteristic that it does not touch air | atmosphere at all.
Therefore, since the article to be packaged hermetically sealed in such a packaging bag does not cause chemical changes such as oxidation, there is an advantage that it can be maintained in its original state for a long time.

  Therefore, if the package that is airtightly filled and is not oxidized, if the air flows backward after opening it (the volume of the general PET bottle etc. There is a problem that the non-oxidation effect accompanying the filling of the broken liquid in the liquid is canceled out.

  In addition, a self-supporting soft packaging bag filled with a liquid material is stored and held, and the container is tilted so that the filled liquid material can be poured out from the spout of the soft packaging bag. The containers disclosed in Patent Documents 3 and 4 have been proposed.

  As described above, the packaging bags disclosed in Patent Document 1 and Patent Document 2 are made of a soft (flexible) packaging bag in order to exhibit the check function of the check nozzle protruding from the side or top. Since it is neither fixed nor self-supporting, it must be stored and held in a holding container when used. The box-shaped containers described in Patent Document 3 (see FIG. 6) and Patent Document 4 (see FIG. 8) disclosed as holding containers for storing and holding the flexible packaging bag are mainly made of paper. Therefore, the strength is weak, and there is a risk of deformation or breakage due to falling during transportation or handling, and the assembly process of the container and the manufacturing process including the packaging of the liquid filling package are complicated and expensive. There was a problem.

  By the way, in the case of a liquid-filled package having a non-return dispensing nozzle, it is essential that the container body be automatically crushed and deformed by atmospheric pressure due to the dispensing of the contents in the container, and reduced in volume. is there. In this respect, the conventional hard plastic PET bottle does not cause the above-mentioned crushing deformation by the content extraction, and therefore, intrusion of air is inevitably allowed instead of the extraction. That is, in order to ensure the function of the non-return dispensing nozzle, the liquid-filled packaging bag is inevitably required to be a soft material.

  On the other hand, the packaging bag made of the soft plastic material described above has the property that it is not self-supporting because it is a soft material, so the existence of a self-supporting outer container is indispensable to support this. Become. Moreover, since PET bottles are gas (oxygen) permeable, they are not generally preferred as containers for soy sauce that does not like oxidation. In this sense, the above-mentioned non-self-supporting soft plastic packaging bag is suitable as a container containing soy sauce. On the other hand, in order to store and hold this bag, a self-supporting hard plastic outer container is used. It can be said that the combination is appropriate.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a liquid-filled packaging body for a non-self-supporting soft material, in which a packaging bag formed by protruding a check nozzle is filled with a liquid package, and to store and hold the same. In a packaging structure composed of a self-supporting outer container that is preferably used for the purpose, the filled liquid package is not oxidized or contaminated, and can always be kept fresh. The object is to propose a liquid-filled packaging structure that will not be deformed or damaged even if it falls over during transportation or handling.

  As a result of intensive studies to overcome the above-described problems of the prior art, the present inventors have developed a liquid-filled packaging structure according to the following summary configuration. That is, the present invention fills a liquid packaging material in an airtight manner in a soft plastic packaging bag in which a liquid pouring nozzle having a check function protrudes from the upper end portion or one side edge upper portion of the packaging bag body.

(6) The film-like liquid pouring nozzle is formed by fusing two thin soft flat laminated films to each other on the outer peripheral edge portion excluding the portion serving as the nozzle base end portion on the packaging bag body side, The central portion is configured as a pouring passage, and the base end portion is fusion-bonded so as to protrude from the upper end portion or one side edge upper portion of the packaging bag body, and the packaging bag body is tilted. When the packaged material is poured out, the inner surface of the laminated film in which the liquid packaged product passes and becomes wet in the dispensing channel is packaged on the inner surface of the dispensing channel. It is a more preferable embodiment that it is formed so as to generate a non-return function that prevents the intrusion of outside air by the mutual adhesion action caused by the retention of the substances.

  According to the liquid-filled packaging structure of the present invention configured as described above, both the regularity and the self-supporting property are obtained by filling a flexible (soft) packaging bag with a liquid such as drinking water, seasoning, or medicine. It is possible to store and hold a non-liquid-filled package and to provide it with independence for use. In addition, according to the present invention, the packaged material is not oxidized or contaminated by filling the packaged package body in an airtight manner while the liquid packaged product is sealed in liquid or deaerated. Furthermore, since the non-return function nozzle is provided, even if the package is repeatedly poured out, it can be kept in a fresh state for a long time. Furthermore, according to the present invention, the outer container is not deformed at the time of transportation or handling, and further, the liquid-filled package body inside is not damaged and the packaged material does not leak out.

  In addition, according to the liquid filling and packing structure of the present invention, the outer container can be easily detached, exchanged and replaced by configuring the outer container to be separable into the main body and the bottom, It is possible to reduce the cost for the conventional boxing operation. Furthermore, the outer container can be reused by exchanging the liquid filling package.

  Further, according to the liquid filling and packaging structure of the present invention, the liquid dispensing nozzle serving as the pouring outlet for the liquid filling and packaging body accommodated therein is accommodated in the pouring port of the outer container, Since the cap can be screwed or engaged with the upper end of the mouth part or closed using the lid, even if the structure falls down or vibrates after opening the liquid dispensing nozzle In addition, there is no fear that the liquid material flows out, and on the other hand, the freshness of the contents can be maintained until it is used up without impairing the characteristics of the film-like check function nozzle.

  In addition, according to the present invention, when a window hole is provided in the body portion of the outer container, the remaining amount and contents of the package can be confirmed, and the body of the liquid-filled package housed in the container Since the portion can be directly pressurized with fingers, it is easy to pour out the package and control the amount of the pour.

It is a figure which shows one Embodiment of the liquid substance filling packaging structure which concerns on this invention. It is a figure which shows one Embodiment of the outer container which concerns on this invention. It is a figure which shows other embodiment of the outer container which concerns on this invention. It is a figure which shows other embodiment of the liquid filling packaging structure which concerns on this invention.

  As shown in FIG. 1 as an embodiment, the liquid-filled packaging structure A according to the present invention hermetically fills liquid material such as drinking water, soy sauce, sauce, and dressing in the packaging bag body 2 of the flexible packaging bag. And the outer container 5 for storing and holding the non-self-supporting liquid-filled packaging body 4 therein and imparting self-supporting properties. In addition, the outer container 5 of this embodiment is comprised from the cylindrical main-body part 5a and the circular bottom part 5b.

  In the present invention, the outer container 5 is deformed at the time of transportation or handling by using a material having a hardness capable of holding the liquid-filled package 4 as the outer container 5, and further, the inner liquid-filled package 4 is There will be no breakage and leakage of the package. In addition, it is preferable to use hard plastics or hard paper such as polyethylene terephthalate (PET) or polypropylene (PP) as the outer container 5, and in particular, PET bottles using polyethylene terephthalate (PET) should be durable and long-lasting. To preferred. Further, as the outer container 5, it is preferable to use a transparent or translucent one. As a result, it is possible to confirm the internal volume, particularly the remaining amount, of the liquid package in the liquid filling package 4 housed inside from the outside of the outer container 5.

  The outer container 5 is most preferably substantially the same shape as the liquid-filled package 4 accommodated therein, but a cylindrical shape, a rectangular tube shape, particularly a flat rectangular tube shape is preferable. And in the case of a PET bottle, the bottom part of this outer container 5 is preferably a petaloid shape in terms of storage of the packaging body 4 and a shape preferable for self-supporting stability. Further, the outer container 5 is for pouring at a position corresponding to the liquid pouring nozzle 1 of the liquid filling package 4 to be stored, that is, at the upper end portion or the upper side edge of the outer container 5 (upper end portion in FIG. 1). By providing the mouth portion 6 and storing the liquid pouring nozzle 1 portion of the liquid filling and packaging body 4 therein, the liquid filling and packing body 4 can be better accommodated in the outer container 5.

  Here, the shape of the pouring port 6 can be a cylindrical shape, a rectangular tube shape, or the like, but in any case, it may be a shape that does not hinder the check function of the liquid pouring nozzle 1. is important. That is, as will be described later, the non-return function of the liquid pouring nozzle 1 is exerted by the mutual adhesion of the two laminated plastic films forming the nozzle 1, and the flatness (flatness) between the plastic films is high. An excellent check effect can be obtained. Therefore, it is necessary that the pouring port portion 6 of the outer container 5 has a shape that does not press down the inner nozzle 1 so that no wrinkles or gaps are generated between the plastic films constituting the nozzle 1. It is.

  The liquid-filled package 4 can be easily stored and held in the outer container 5 from the lower end of the main body 5a by removing the bottom 5b of the outer container 5, and the liquid-filled package 4 can be replaced. Can be done easily. Such an outer container 5 is provided with a screw on the inner side surface and the bottom side surface of the bottom part 5b at the lower end of the main body part 5a and screwing each other, or by changing the outer diameters of the lower end of the main body part 5a and the upper end of the bottom part 5b. The part 5a can be assembled integrally by a method of fitting the bottom part 5b.

  Further, when using the liquid-filled packaging structure A, the packaging bag body 2 is suppressed in order to prevent the internal liquid-filled package 4 from slipping off and the liquid dispensing nozzle 1 from being removed from the dispensing port 6. It is preferable that the upper corners and / or the lower corners are fixed by being bonded or welded to the inner surface of the outer container 5, whereby the liquid package can be discharged stably.

  By the way, the pouring nozzle 1 projecting from the packaging bag main body 2 is an outside of the two thin flat soft laminated plastic films excluding the portion serving as the nozzle base end on the packaging bag main body 2 side. The peripheral portions are fused together, the central portion is configured as an extraction passage, and the base end portion is fusion bonded so as to protrude from the upper end portion or one side edge upper portion of the packaging bag body 2. . And when this pouring nozzle 1 inclines the packaging bag main body 2 and pours out a to-be-packaged product, the filled liquid to-be-packaged object passes through the pouring passage of this pouring nozzle 1 The inner surfaces of the laminated plastic films that are in a wet state have a self-sealing check function that prevents the intrusion of outside air due to the mutual contact action caused by the objects to be packaged staying on the inner surface of the pouring passage. It is formed.

  Accordingly, the liquid-filled packaging body 4 formed by filling the packaged body into the flexible packaging bag formed by projecting the dispensing nozzle 1 on the upper end of the packaging bag main body 2 or the upper part of one side is itself By tilting, a required amount of liquid package can be poured out from the bag. However, when the liquid filling package 4 is returned to its original standing posture, the liquid filling package 4 is returned from the opening of the pouring nozzle 1. As the liquid material stops flowing out, the liquid always remains in the passage (stagnation) and gets wet. Therefore, at the same time as the stop, the inner surfaces of the laminated plastic film are brought into close contact with each other by the capillary action of the intervening packages, and therefore the nozzle provided at the tip of the dispensing nozzle 1 The opening remains in close contact, and the entry of outside air into the packaging bag main body 2 is reliably prevented (backflow prevention). As a result, in the liquid-filled package 4 having such a pouring nozzle 1, the liquid package to be filled in the packaging bag body 2 is not only being poured out, but is being poured out and after being poured out. In this case, it is completely shielded from contact with the outside air to be protected, so that oxidation, contamination and the like of the packaged items in the bag are effectively prevented.

  By the way, the liquid package to be filled in the flexible packaging bag is poured out by cutting off the planned opening portion 1a specified by adding a tear guide line and a notch formed near the tip of the pouring nozzle 1. After the opening by cutting out the planned opening portion 1a, the liquid filling and packing structure A of the present invention is liquefied by tilting so that the nozzle opening (pouring spout) faces downward. Packaged items can be discharged. In this case, the outflow of the liquid package can be basically performed under the extrusion pressure (hydraulic pressure) of the package, but the pouring nozzle 1 made of a soft laminated plastic film is the liquid In addition to the action of the water head pressure of the article to be wrapped, the front and back laminated plastic films can be separated from each other by pressing the body part of the liquid-filled packaging body 4 with fingers through the window hole 10 described later. At the same time as the pouring passage is opened, the nozzle opening is also opened and the packaged material is poured out. Further, the amount of the packaged material to be dispensed can be controlled by the tilt angle of the liquid material filled packaging structure A and the degree of pressurization of the liquid material filled package body 4 as described above.

  However, after opening the pouring nozzle 1 in this way, the liquid filling and packing structure A falls down and the water head pressure of the packaged item in the bag acts on the pouring nozzle 1. The two laminated plastic films that make up 1 are separated from the front and back sides against the intermolecular force between the film and the liquid-film caused by the liquid material, creating a large gap. There was a risk of the package being leaked because the exit passage was opened.

  Therefore, in the present invention, as shown as one embodiment of the outer container 5 in FIG. 2, a screw 6a is formed on the outer peripheral surface of the pouring port 6 and a screw 8a is formed on the inner peripheral surface thereof. 8 is preferably screwed to each other so as to cover the upper end of the pouring port 6, so that even if the liquid-filled packaging structure A falls down unexpectedly, Leakage of the article to be packaged from the pouring nozzle 1 located can be prevented. Further, the upper end portion of the pouring port portion 6 is provided with a locking projection 8b formed on the inner peripheral surface of the cap 8 as shown in FIG. You may apply a lid | cover by making it latch to the latching hollow 6c formed in 6 outer peripheral surfaces.

  Further, as a method of applying the outer container 5, as shown in another embodiment of FIG. 3, a lid 9 is attached to the upper part of the pouring port 6 so as to be opened and closed, and the lid 9 is attached to the pouring port. 6, the cover 9 is covered with the locking recess 9 b provided on the outer periphery of the pouring port 6 by engaging the locking protrusion 9 a provided on the inner periphery of the lid 9 with the cover 9. It can be securely fitted on the portion 6.

  Next, other embodiment of the liquid filling packaging structure A of this invention is described. In this embodiment shown in FIG. 4, the outer container 5 is configured to be separable into a rectangular tube-shaped main body 5a and a bottom body 5b having the same shape. By making the outer container 5 separable in this way, the liquid filling package 4 can be easily stored and held in the outer container 5 and the liquid filling packing body 4 can be easily replaced. Can do. In such an outer container 5, a screw is provided at the lower end of the main body part 5a and the upper end of the bottom body part 5b, and the outer diameter is different between the lower end of the main body part 5a and the upper end of the bottom body part 5b. The body portion 5a can be assembled integrally by a method of fitting the bottom body portion 5b.

  Further, in the present invention, as shown in FIG. 2, it is preferable to form a circular, elliptical, rectangular or other window hole 10 in the vicinity of the center of the trunk of the outer container 5 or near the lower part. 10 adjusts the discharge flow rate of the article to be packaged from the dispensing nozzle 1 so that the body of the liquid-filled package 4 stored in the outer container 5 can be directly pressurized with fingers or the like. Works effectively in making it possible.

  The liquid filling and packing structure A of the present invention can be variously selected according to the capacity of the liquid filling and packing body 4 (2 liters, 1 liter, 750 cc, 500 cc, 250 cc, 200 cc, etc.) stored in the container A. Can be selected and used.

  The liquid-filled packaging structure of the present invention is not limited to the illustrated examples, and it is possible to partially change the configuration without departing from the spirit of the present invention, and seasoning such as soy sauce, sauce, dressing, etc. In addition to liquids and various beverages, it can also be used as a filling packaging structure in which viscous materials such as mayonnaise and cosmetics are hermetically filled.
