Description

  The present invention relates to a non-self-supporting liquid-filled packaging body filled with a liquid or viscous package material that may contain foods and drinks, pharmaceuticals, cosmetics, various liquids, powders, granules, etc. And a liquid-filled packaging structure comprising an outer container for storing and holding it to provide self-supporting properties.

  Conventionally, as a liquid-filled package, for example, in a soft packaging bag having a non-return type film-like pouring nozzle, a liquid-filled package of the type to be filled with the liquid package is disclosed in Patent Documents 1 and 2, etc. It is disclosed.

  In this liquid-filled package, when the film-like pouring nozzle provided on the upper side edge of the packaging bag pours out the liquid package filled in the bag, the packaging bag body itself shrinks or collapses. This is characterized in that the outside air can be prevented from entering the bag. That is, the pouring nozzle simultaneously shuts off the pouring of the liquid packaged contents (contents), and the pouring passage in the pouring nozzle is automatically sealed by wetting by the liquid packaged material, and the packaging bag It has the feature of exhibiting a check function (self-seal check function) that prevents the entry of outside air into the inside.

  In addition, the applicant previously described the opening of the dispensing passage when the dispensing of the packaged article is stopped while the self-sealing check function of the film-like dispensing nozzle described in Patent Documents 1 and 2 remains unchanged. The film-pouring nozzle can be used as a packaging bag that allows smooth pouring and finer adjustment of the pouring amount without impairing the pouring characteristics of the product, and has good liquid drainage and does not cause dripping. An application has been filed for a packaging bag that protrudes obliquely upward from the upper end of the bag body (not disclosed at the time of application).

  Since all such liquid-filled packages are formed of a soft laminated film, they are non-self-supporting, and it is inconvenient to use them alone as they are. As shown in Document 3, it was stored and held in a self-supporting outer container.

  By the way, in patent document 3, the overhang | projection part is provided in the position corresponding to the film-like extraction nozzle of the non-self-supporting liquid substance filling packaging body to accommodate in the upper part of one side edge of an outer container, and the lower end from the upper end of this overhang part A curvilinear tearing guide rod for exposing the film-like dispensing nozzle is provided.

  In this packaging structure, first, the overhanging portion of the outer container is cut along the tear guide rod, the tip portion of the film-like pouring nozzle is exposed to the outside, and then the tip portion of the film-like pouring nozzle is fingered or the like Since the two-stage opening operation of the outer container and the film-like extraction nozzle is required so that the spout can be opened by tearing by means of a tear, the opening procedure is complicated and it is difficult for children, elderly people, etc. There was a possibility that the film-like pouring nozzle could be deformed or damaged by opening it from a different position or forcibly tearing it.

  Further, the film-like dispensing nozzle is opened by tearing with fingers or the like starting from an opening means such as an I notch or a V notch provided near the tip, but there are individual differences in tearing force, tearing direction, etc. Therefore, it may be torn in an unintended direction, or fuzz due to the elongation of the film may occur on the tearing end surface, and the liquid package will adhere to it, resulting in poor drainage and dripping. There was a fear.

  Further, in this packaging structure, the tear guide rod of the overhanging portion of the outer container and the opening opening position of the film-like dispensing nozzle located inside are close to each other, so that the tip of the film-like dispensing nozzle during the tearing operation of the outer container There is a risk that it will be opened accidentally, for example, when a finger touches it. Therefore, although measures such as changing the opening direction (from top to bottom) of the film-like pouring nozzle and the opening direction (from bottom to top) of the overhanging part are taken, it is not sufficient, and improvement has been desired. .

  Accordingly, the present invention provides a liquid material that is easy to open, does not cause deformation or breakage of the film-like dispensing nozzle, and can suppress the occurrence of fluffing on the tear end surface of the film-like dispensing nozzle. An object is to provide a filled package.

The present invention has been developed to achieve the above object, and the gist of the invention is that it is a soft product formed by projecting a film-like dispensing nozzle on the upper edge or upper side edge of a packaging bag body made of a laminated film. In a liquid-filled packaging structure comprising a liquid-filled packaging body filled with a liquid or viscous packaged article in a packaging bag and an outer container for storing and holding the liquid-filled packaging body ,
The outer container is an overhanging sachet that can be cut out along the tear guide ridge at a portion corresponding to the tip of the film-like dispensing nozzle of the flexible packaging bag and the tip of the film-like dispensing nozzle can be exposed. And the inner surface of the protruding sachet portion and at least a part of the outer surface of the distal end portion of the film-like dispensing nozzle are fused, and the distal end portion of the film-like dispensing nozzle is The liquid-filled packaging structure is characterized by being capable of tearing and opening simultaneously with the cutting of the overhanging sachet portion along the tear-inducing fold through the fusion part between the sachet portion and the sachet portion.

  In the present invention, the tearing guide rod starts from the side edge upper portion of the outer container opposite to the protruding sachet portion, passes through the upper edge seal portion of the outer container, and the upper portion of the protruding sachet portion. It becomes a more preferable solution means that it is provided continuously from the bottom to the bottom.

  In the present invention, since at least a part (cut-off portion) of the outer surface of the tip end portion of the film-like pouring nozzle is fused to the inner surface of the overhanging sachet portion of the outer container, it follows the tear-inducing ridge of the overhanging sachet portion. Along with the cutting, the tip of the film-like dispensing nozzle can be opened. Therefore, in the present invention, the opening of the outer container and the film-like dispensing nozzle can be performed simultaneously by one operation, and even a child or an elderly person can easily perform the opening operation. Furthermore, according to the present invention, since the tip end portion of the film-like dispensing nozzle is instantaneously cut off as the overhanging sachet portion is cut out as described above, the elongation of the film on the opening end face is reduced, and the fluffing occurs. There is no occurrence and dripping can be effectively suppressed.

  Further, in the present invention, the tear guide bag of the outer container passes through the upper edge of the outer container, starting from the side edge opposite to the film-like pouring nozzle of the stored liquid filling package, Since it is provided from the upper part to the lower end of the part, the tearing route becomes long and can be easily opened with a small force by the tear propagation force accompanying tearing from the starting point at the position of the protruding sachet part. In addition, the overhanging sachet portion can be cut along the tear guide bag by pulling it toward the outside of the outer container in a state where the starting point portion is gripped. There is no possibility that an excessive force is applied to the film-like pouring nozzle, and the nozzle is not bent and deformed or damaged.

  Furthermore, since the starting point of the tearing guide rod is located on the side edge opposite to the film-like dispensing nozzle of the stored liquid-filled package, the overhanging sachet portion where the film-like dispensing nozzle is located at the time of tearing There is no need to grip the film, and erroneous opening of the film-like dispensing nozzle can be suppressed.

It is a top view which shows one Embodiment of the liquid filling packaging structure of this invention. It is a top view which shows other position embodiment of the liquid filling packaging structure of this invention. It is the elements on larger scale which show the tearing opening method along the tear induction | guidance | derivation flaw of the outer container of the liquid filling packaging structure of FIG.

Embodiments of the present invention will be described below based on the drawings.
As shown in FIG. 1 as an embodiment, a liquid-filled packaging structure 1 according to the present invention is a liquid-filled package in which a soft or flexible packaging bag 2 is filled with a liquid or viscous package. 3 and an outer container 4 for storing and holding the package 3.

As the outer container 4, a non-self-supporting liquid-filled package 3 is housed, and a cylindrical container for providing self-supporting properties and formability, for example, a stack having a self-supporting bottom portion 4 a as shown in FIG. 1 A flexible packaging bag (standing pouch) made of a plastic film is preferably used.
In addition to the plastic film, the outer container 4 can be formed of a flexible material such as paper, limestone (calcium carbonate amount over 50%) and a plastic composite material, metal, or the like.

  In addition, after the liquid-filled package 3 is stored in the outer container 4, in the drawing, for example, the outer surface of the packaging bag body 2a and the inner surface of the outer container 4 are disposed at the upper positions on both side edges of the packaging bag body 2a. By fusion-bonding each other (seal portion 12), the outer container 4 is firmly fixed.

  The liquid-filled package 3 includes a packaging bag body made of a laminated plastic film having a base film layer and a sealant layer, and a film-like note projecting obliquely upward at the upper edge of the packaging bag body in FIG. In the packaging bag 2 composed of the outlet nozzle 5, for example, the packaged object is hermetically sealed in a state of being evacuated by filling with a liquid seal, or filled with a gas such as nitrogen diffused in the packaged object. It is formed by doing.

  The film-like pouring nozzle 5 preferably has a self-seal check function, so that the packaged item in the packaging bag 2 is in contact with the outside air both before and after pouring. Therefore, it is possible to effectively prevent oxidation, fouling and the like of the packaged item in the bag.

  The self-seal check function means that the liquid-filled package 3 is opened in the state in which the leading end portion of the film-like dispensing nozzle 5 is opened 6 when the packaged material is poured out from the liquid-filled package 3. In this way, the inner surface of the dispensing passage 8 of the dispensing nozzle 5 is largely separated by the head pressure of the packaged item, etc., and the tip opening 6 is opened to dispense the packaged item as required. I do. At this time, since the packaging bag body 2a contracts or collapses according to the volume of the packaged material, the packaging bag body 2a can be poured out without taking outside air into the liquid-filled package 3.

  On the other hand, when stopping the dispensing of the article to be packaged, the liquid-filled package 3 is raised and returned, and simultaneously with the raising and returning, the dispensing passage 8 is released from the head pressure of the article to be packaged. In addition to returning to the original shape under the generation of negative pressure due to the return flow of the article to be packaged into the packaging bag body 2a, the inner surfaces wetted by the thin film of the article to be packaged This is a function of automatically sealing and sealing the dispensing passage 8 by adsorbing with negative pressure under the assistance of a reduced-pressure atmosphere in the main body 2a.

  Although the film-like dispensing nozzle 5 is provided so as to protrude obliquely upward from the upper end of the packaging bag body 2a in FIG. 1, the present invention is not limited to this, and the film-like dispensing nozzle 5 is packaged. You may provide it protruding toward the side from the upper side edge of the bag main body 2a.

  The outer container 4 has an overhanging sachet portion 7 at a position corresponding to the film-like pouring nozzle 5 of the stored liquid-filled package 3, and the tip end portion of the film-like pouring nozzle 5 is in the overhanging sachet portion 7. Will be stored. At the time of use, at least the tip portion of the film-like pouring nozzle 5 located on the inner side can be exposed to the outside by cutting off the protruding sachet portion 7 along the tear guide rod 9.

  In the present invention, at least a part of the outer surface on the tip side of the planned opening position of the film-like pouring nozzle 5 is fused to the sealant layer on the inner surface side of the protruding sachet portion 7 (fused portion 11). There is a feature. By adopting such a configuration, when the protruding sachet portion 7 is pulled in the direction indicated by the arrow in FIG. 1 and the protruding sachet portion 7 is cut along the tearing guide rod 9, the film is poured out via the fused portion 11. The tip portion of the nozzle 5 is pulled together, and the tip portion of the film-like dispensing nozzle 5 is torn and opened.

At this time, the tip portion of the film-like pouring nozzle 5 is instantly cut along with the tearing guide bag 9 of the overhanging sachet portion 7, so that it is torn and opened by conventional fingers or the like. In comparison with this, the elongation of the packaging film at the opening end of the film-like dispensing nozzle 5 is suppressed, the occurrence of fluffing is reduced, and the occurrence of dripping can be effectively prevented.
Further, when opening the film-like dispensing nozzle 5, it is not necessary to touch the tip of the film-like dispensing nozzle 5 with a finger or the like, and the hygienic and safety of the film-like dispensing nozzle 5 can be ensured.

  FIG. 2 shows another embodiment of the tear guide rod 9, and the upper edge seal of the outer container 4 starts from a tear notch 10 provided on the upper side edge of the outer container 4 on the side opposite to the overhanging pouch 7. It passes over the part 4a and is provided from the upper part to the lower end of the overhanging sachet part 7.

  The tearing along the tear guide rod 9 is performed by first grasping the tear notch 10 with both fingers and pulling the top upward from the tear notch 10 as indicated by the arrow in the enlarged view of FIG. The tear is stretched along the tear guide rod 9 and propagates at a stretch to the lower end of the pouch portion 7.

  According to the tear guide rod 9, since the starting point is the tear notch 10 position, when the outer container 4 is torn and opened, the protruding sachet portion 7 where the film-like dispensing nozzle 5 is located is gripped as in the prior art. Therefore, there is no possibility that the film-like dispensing nozzle 5 will be unintentionally opened at the time of tearing along the tear guide rod 9.

  In addition, since the tearing route is longer than the conventional one, the tear propagation force from the tear notch 10 allows the tearing to proceed vigorously with a small force from the upper part to the lower end of the overhanging pouch part 7. As described above, the overhanging pouch portion 7 can be cut along the tear guide rod 9 by grasping the tear notch 10 portion and pulling upward toward the outer container 4. Along with this, there is no fear that an excessive force is applied to the film-like dispensing nozzle 5 positioned inside, and the nozzle 5 is not bent and deformed or damaged.

  The tear guide rod 9 is a single rod provided extending in the minus direction in the width direction of the laminated plastic film, a plurality of rods perforated in the width direction, and a gap in the width direction. A plurality of small hole-shaped wrinkles provided, or a melt mark provided continuously or intermittently with a laser beam or the like, can be formed with an appropriate shape and number of wrinkles. The depth, length, and other dimensions of such a tear guide rod are selected according to the thickness of the laminated plastic film, the constituent material, and the like.

  The technology adopted in the liquid filling and packaging body according to the present invention is not limited to the exemplified liquid filling and packaging structure, but also can be applied to filling containers of powder and granular materials and as other means for opening other containers. It is valid.
