To provide a body storage container.

The packaging container of the present invention comprises a flexible packaging bag body formed by fusion-bonding a sealant layer of a laminated film having a base film layer and a sealant layer, and sealant layers on both sides. A non-return dispensing nozzle having a self-sealing function, wherein a thin flat laminated film is fused and joined around the dispensing passage of the packaged item in the bag except for the base end side, Filled with a liquid package in a packaging bag in which the sealant layer on the outer surface of the base end of the pouring nozzle is fused and bonded to the upper end or lower end of the packaging bag body in a protruding manner to the side. A storage container made of paper or synthetic resin that houses a package body formed by packaging and gives the package body self-supporting property and formability, and the bottom portions of the two side plates are mutually connected by the bottom wall. And two tops One side plate of the storage container having a flat plate shape is overlapped with one side of the non-return dispensing nozzle protruding to the side of the packaging bag body to cover the entire dispensing nozzle, and the dispensing nozzle is A packaging characterized by being provided with a protruding piece that can be folded / folded toward the other side plate of the storage container and separated from the main body of the storage container by removing the latching tongue piece together with the pouring nozzle inside. It is a body storage container.

In the present invention,
(1) The hooking tongue piece protrudes from the tops of the two side plates so as to sandwich the upper fusion joint portion of the check pouring nozzle toward the protruding direction of the check pouring nozzle. That it is installed,
(2) The protruding piece is separated from the storage container by tearing along a tear guide rod provided on an outer edge of the latching tongue piece and one side plate of the storage container,
(3) A slit is provided in the other side plate of the storage container, and an insertion portion to the slit is provided in the protruding end portion of the protruding piece.
(4) The insertion portion of the protruding piece is provided with a warp that engages with at least one of the upper edge and the lower edge of the slit of the other side plate,

(7) Provided with a holding means for maintaining the hooking tongue piece left uncut by the separation of the protruding piece in a folded posture together with the dispensing nozzle with the non-return dispensing nozzle inside.
(8) The holding means is formed on a projecting piece projecting laterally from the top end of the hooking tongue piece and a plate-like top part of the storage container, so that the projecting piece can be fitted and engaged. And
Is a more preferred embodiment.

In the packaging container of this invention, a protruding piece that protrudes to the side of the container main body and overlaps with one side of the non-return dispensing nozzle and covers the entire dispensing nozzle, together with the dispensing nozzle By folding it by 90 ° or more, the side protruding portion from the storage container can be sufficiently removed, and the storage container can have a narrow slim shape. According to this, it is possible to effectively reduce the occupied space for packaging storage, transportation, display, etc. of the container storing the package, and storing based on the smart and slim shape of the storage container. The number of consumers who pick up the container and determine the product can be greatly increased.
Here, it is not essential to the present invention to completely remove the lateral projecting portion from the storage container.

Note that the folded protruding piece is in a state along the other side plate of the storage container until the start of use, for example, by joining to the other side plate of the storage container using an attachment member such as a hook-and-loop fastener or glue. However, when the other side plate of the storage container is provided with a slit, and the protruding end portion of the protruding piece is provided with an insertion portion to the slit, the storage container can be Without using an external member or the like, it can be held in a certain slim shape, and the above effects can be further improved.

By the way, the non-return dispensing nozzle that is folded together with the protruding piece and is located inside the protruding piece includes at least a sealant layer on both the front and back surfaces and a uniaxial or biaxially stretched base film layer between them. Because it consists of two folded sheets of thin flat laminated film, or even when folded together with the protruding piece as described above, it will not be permanently deformed in a folded state, Pull out the protruding piece from the slit and fold it up with the check dispensing nozzle, open the check dispensing nozzle from the protruding piece by excising the protruding piece etc., and restore the original shape based on the elastic restoring force of the laminated film Can almost return.
Therefore, as in the case of the conventional non-return dispensing nozzle, the packaged item inside the bag is blown into the packaging bag body under the deformation of the packaging bag body due to the tilting of the packaging body, and thus the packaging container. It is possible to pour out without taking in, and by returning the packaging body, and consequently the storage container, to the original standing posture, the action of the non-returning pour nozzle that exhibits the self-sealing function, By sealing the liquid package under the thin film, it is possible to sufficiently prevent the outside air from entering the packaging bag body.
Subsequent re-pouring will be carried out in the same manner as described above under the shape of the package and storage container, under the opening of the pour-out passage based on the action of water head pressure, etc. The discharge passage is also sealed in the same way as the discharge is stopped.

Here, when the insertion part of the protruding piece is provided with a warp that engages at least one of the upper edge and the lower edge of the slit of the other side plate, the storage container containing the package is stored in a box and stored. In such a case, it is possible to effectively prevent the protruding piece from unintentionally coming out, and thus the unexpected increase in the space occupied by the storage container.

Further, in the case where a plurality of perforated perforations are provided on the protruding piece to guide the removal of the insertion portion, the warp provided on the insertion portion of the protruding piece is engaged with the slit, etc. Even if it is difficult to pull out from the slit, the insertion part can be cut out from the perforated position of the perforation. The exit nozzle can be returned to a form that can sufficiently exhibit the self-sealing function.

This is more effective when, for example, each of the protruding piece excluding the latching tongue piece and a part of one side plate is removed by tearing along the tear guide rod.
This tearing guide rod can be formed by continuously or intermittently thinning the protruding piece etc. by irradiating a laser beam, but it has been formed by a plurality of perforated holes as usual. In some cases, anyone can immediately and accurately see the presence of the tear-inducing flaw.

By the way, it is preferable that the tear guide rod has a curved shape or a broken line shape, and according to this, the tear guide rod can be handled safely without fear of unexpectedly separating the tear guide rod.

In addition, the latching tongue piece protruding from the top of the storage container, which is left uncut by cutting along the tear guide rod, is provided so as to sandwich the upper fusion joint portion of the check dispensing nozzle. With the folding / folding of the latching tongue piece, the check dispensing nozzle located on the inner side can also be folded / folded. Therefore, according to the folding of the latching tongue piece, the dispensing passage of the non-return dispensing nozzle can be closed, and if the latching tongue piece is folded and pressed with fingers, Even if the storage container is artificially vibrated in order to mix the items uniformly, the leakage of the liquid packaged item in the bag can be sufficiently suppressed.

Further, when the holding means for maintaining the hooking tongue piece in the folded posture is provided, in addition to the above-described effect, the storage container may be inadvertently laid down after the pouring passage of the check pouring nozzle is once opened. Even if it does, leaking out of the liquid in-bag package can be prevented sufficiently.
As the holding means, an external member such as a clip, a line, a point or a hook-and-loop fastener attached to the storage container can be used, and the same effect can be expected in any case.

And the holding means is formed on the top of the storage container and the protruding piece having an appropriate contour shape that protrudes laterally from the top of the hooking tongue piece, and enables the fitting of the protruding piece. When it is configured with a notch, it is not necessary to use an external member or an attachment member for the storage container, and the storage container can be manufactured inexpensively and easily.

It is the front view and back view which show the storage container which accommodated the package based on this invention in the protrusion attitude | position to the side of a protrusion piece. It is a perspective view which shows the state which inserted the insertion part of the protrusion piece into the slit of a side plate while bending a protrusion piece with a non-return dispensing nozzle inside. It is a front view which shows the state which cut off the protrusion piece. It is a perspective view which illustrates the package stored in a storage container. It is explanatory drawing which shows the latching state to the notch provided in the storage container main body of the protrusion piece. It is an expanded view of the storage container shown in FIG. It is a perspective view which illustrates the conventional storage container with a package.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, 1 denotes the entire storage container, 2 denotes one of the two side plates located on the front side, and 3 denotes the other of the two side plates located on the back side.
The storage container 1 separates the bottoms of the two

side plates

2 and 3 from each other by a bottom wall, which will be described later. None, with a flat plate with two tops. And the outer contour shape of the intermediate part of the lower end part of the storage container 1 and a top part makes | forms the curved shape from which a cross section protrudes on the outer side of a container.

In such a storage container 1 shown in the figure, one side plate 2 on the front side overlaps with one side of a non-return dispensing nozzle 4 projecting to the side of the packaging body described later, and the entire dispensing nozzle 4 is covered. The cover 5 has a protruding piece 5 that can be folded at approximately 180 ° as shown in FIG.

In such a storage container 1, an insertion portion 7 to a slit 6 provided on the other side plate 3 of the storage container 1 is provided at the protruding end portion of the protruding piece 5 that protrudes the most. In the present invention, the slit 6 and the insertion portion 7 may not be provided, and the protruding piece 5 and the other side plate 3 may be engaged with each other by attaching a surface fastener or glue.

Also, on the upper part of the protruding piece 5, a latching tongue piece 24 protruding from the main body side of the storage container 1, that is, the side of the

side plates

2, 3 and edged by a tear guide rod 8 described later is provided. In addition, this latching tongue piece 24 is provided so that the upper side fusion | melting junction part of the non-return pouring nozzle 4 of the package body accommodated and hold | maintained in the storage container 1 may be clamped from the front and back.

And the protruding piece 5 and one side plate which are provided in the outer edge of the latching tongue piece 24 and one side plate 2 of the storage container 1 along the curved or broken line shape, in the figure, the curved tearing guide rod 8. As shown in FIG. 3, most of the non-return dispensing nozzle 4 is exposed by the cutting of 2. That is, the check pouring nozzle 4 is almost entirely released from the restraint by the protruding piece 5 except for the hooking tongue piece 24 portion. Note that the check dispensing nozzle 4 is folded together with the protruding piece 5, but the original shape is obtained by the elastic restoring force of the laminated film constituting the check dispensing nozzle 4 by releasing from the restraint by the protruding piece 5 as described above. The self-seal check function can be fully exhibited.

2 shows a state in which the protruding piece 5 is folded with the non-return dispensing nozzle 4 inside the bend, and the insertion portion 7 is inserted into the slit 6 provided in the other side plate 3. Then, since the protrusion piece 5 will be folded over the whole, the protrusion part which causes an increase in an occupation space will be removed from the storage container 1 which accommodated the package body, and the storage container 1 will be the whole of the height direction. It can be slim and smart with a nearly uniform width across. For this reason, boxing storage, transportation, display, and the like of the storage container 1 can be performed in a space-saving manner, and the opportunity for picking up the storage container 1 and determining the product can be greatly increased.
In addition, in the place shown in FIG. 2, although the protruding piece 5 is made into the substantially uniform width | variety over the whole height direction by completely folding from the protrusion base position, the protruding piece 5 of the storage container 1 is shown. It is also possible to make it protrude somewhat outward.

FIG. 4 is a perspective view illustrating the package 10 that is stored in the storage container 1 and has no self-supporting property or formability in a standing posture. This package 10 includes a stretched base film layer and a sealant layer, and a sealant layer of a packaging film having a laminated structure, which may have a vapor deposition layer, an intermediate layer, and the like having a required physical property. As shown, the flexible packaging bag body 11 is formed by fusion bonding in a substantially L shape in the vertical and horizontal directions, and a sealant layer is provided on both the front and back sides of the stretched base film layer, which also has the required physical properties. It consists of a thin flat laminated film that may have a vapor-deposited layer, an intermediate layer, etc., and has a distal end of the outlet passage 13 around the outlet passage 12 of the package in the bag except for the base end side 4a. And a non-return dispensing nozzle 4 having a self-sealing function, wherein the sealant layer on the outer surface of the base end portion of the non-return dispensing nozzle 4 is connected to the upper end portion or the lower end of the packaging bag body 11. Side, protruding sideways A desired liquid or viscous packaged material is filled and packaged under deflation in a packaging bag 12 which is fusion bonded and the upper end or lower end of the packaging bag body 11 is opened, and the upper end or lower end is opened. The ends are fusion-bonded as shown by hatching in the figure.
That is, the package 10 is a liquid seasoning, soup, dressing, wine, liquor, and other liquid packaging items that can also be made into a viscous material, into the packaging bag 12, and in-liquid seals, It can be configured by filling and wrapping under evacuation with a foreign matter seal or the like and, for example, fusion bonding the lower end open end.

Here, the non-return dispensing nozzle 4 that protrudes laterally from the upper end portion of the flexible packaging bag body 11 is, for example, under a half-fold of one thin laminated film or two thin laminated films. Under the superposition, the sealant layers facing each other are fused and joined as shown in a satin-like shape with dots in the drawing at the peripheral edge portion excluding the base end side 4a that will be located in the packaging bag body 11. Thus, the extraction passage 13 is defined inside the fusion bonded portion 4b.
This non-return dispensing nozzle 4 cuts the tip sealing portion 4c, for example, at the position where the V-notch 14 is formed, as shown by a two-dot chain line in the figure, so that the packaging bag storage space 12a of the packaging bag 12 is provided. A tip opening can be formed in the extraction passage 13 that communicates.

Moreover, according to the non-return dispensing nozzle 4, the packaging body 10 is tilted together with the storage container 1 in a state where the tip opening is formed in the dispensing passage 13. Thus, the pouch 13 can be opened without taking in the outside air in the package 10 based on the collapse deformation of the packaging bag body 11 and the like.
On the other hand, under the interposition of the thin film of the packaging material in the bag into the pouring passage 13 wetted by the liquid packaging material in the bag by returning the packaging body 10, and thus the storage container 1 to the standing posture, By immediately bringing the inner surface of the dispensing passage 13 into close contact, the self-sealing function of the non-return dispensing nozzle 4 can be reliably prevented from entering the package 10.
In addition, the non-return dispensing nozzle 4 shown in the figure is fusion-bonded to the inner surface of the packaging bag main body 11 by a reinforcing seal portion 15 which is also shown by hatching in the lower end portion of the drawing, and the bonding strength is increased. Therefore, even if the package internal pressure is increased, unintentional peeling does not occur in the fusion bonded portion 4b of the check dispensing nozzle 4.

A package 10 as shown in FIG. 4 having such a check pouring nozzle 4 is placed in a storage container 1 which can be made of paper or synthetic resin, as illustrated in FIGS. Based on the inherent rigidity of the storage container 1, the storage container 1 is stored in a standing position, and is provided with a self-supporting property and a formality. It will be packed, stored, transported and displayed in a compact form.
In this case, the fusion bonded portion 10a at the upper end of the package 10 has its outer surface bonded to the inner surface of the two flat plate-like portions 1a at the top of the main body of the storage container 1 by adhesive bonding, fusion, or the like. Is done.
By the way, the lower end of the main body of the storage container 1 is provided with a bottom wall that has a polygonal contour as will be described later, and closes the lower end of the main body. It is unnecessary to increase the bonding strength of the fusion bonding portion 10a at the upper end of the packaging body to the plate-like portion 1a of the main body of the container 1 to such an extent that the weight of the packaging body 10 can be suspended and supported.

1 and 2, the two through holes 20 provided in the two flat plate-like portions 1 a at the top of the main body of the storage container 1 are the upper ends of the packaging body 10 stored in the storage container 1. It is for inspecting by optical means or visual inspection whether the fusion-bonding part 10a exists in an appropriate position. On the other hand, the vertically long oblong through hole 21 in the vicinity of the cutting position of the protruding piece 5 is for checking the filling amount, consumption amount, etc. of the packaged object in the packaging body 10. The circular through hole 22 between the top and the lower end of the container is hooked on the edge, and the container 1 is moved or transported with the packaging body 10 as a hook engaging part or the like. The body 10 is pressed directly to pour out the packaged items in the bag under pressure.

The storage container 1 as described above is shown in FIG. 2 with the protruding piece 5 formed on one side plate 2 in a state in which the above-described packaging body 10 is stored, with the non-return dispensing nozzle 4 positioned inside. Thus, by folding the other side plate 3 side and inserting the tip insertion part 7 into the slit 6 formed in the side plate 3, a slim and smart form as shown in the figure is obtained.
According to this, since the occupation space inherent to the protruding piece 5 can be eliminated almost or not at all, the storage container 1 can be compactly and efficiently boxed, stored, transported, displayed, etc. Due to the good appearance, it is possible to expect a large increase in the number of users who pick up the storage containers 1 displayed.

In such a storage container 1, a warp 7 a that engages with the insertion edge 7 of the protruding piece 5 and at least one of the upper and lower edges of the slit 6 of the other side plate 3, as shown in FIG. Is effectively removed from the unintentional escape of the insertion portion 7 from the slit 6 based on the engagement of the warp 7a with the upper edge of the slit, and thus the possibility of an increase in occupied space due to this escape. it can.
Here, the warp 7 a can be engaged only with the lower edge of the slit 6, or can be engaged with both the upper edge and the lower edge of the slit 6.

Further, when a plurality of perforated perforations 23 are provided on the protruding piece 5 to guide the cutting of the insertion portion 7, a warp 7 a is provided on the insertion portion 7 when the packaged material in the bag is poured out. Regardless of whether or not the insertion portion 7 is inserted into the slit 6, the insertion portion 7 can be cut along the perforated hole 23, and the protruding piece 5 or the like can be cut along the tear guide rod 8. It can be easily and quickly torn and excised.

And when the tear guide rod 8 is also formed by a plurality of perforated holes, regardless of age or sex, the predetermined tear position is clearly and surely visually confirmed, and the desired tear is achieved. Can be realized.

By the way, the latching tongue piece 24 left uncut by the resection along the tear guide rod 8 is folded with the non-return dispensing nozzle 4 inside and the upper fusion joint portion of the dispensing nozzle 4 being sandwiched, In the case where the holding means for maintaining the folded state is provided, even after opening the dispensing passage 13 of the non-return dispensing nozzle 4, the storage container 1 is unexpectedly laid down, the artificial vibration of the storage container 1, etc. It is possible to sufficiently prevent the liquid in-bag package from getting wet unintentionally.
As the holding means, an external member such as a clip, a snap, a hook-and-loop fastener, or other attached members can be used.

In addition, when the container 1 is simply mixed uniformly by shaking the storage container 1 intentionally, the hooking tongue piece 24 is folded with the check dispensing nozzle 4 with fingers. By holding and sealing the dispensing passage 13 of the check dispensing nozzle 4, it is possible to prevent leakage of the packaged items in the bag.

On the other hand, the holding means protrudes laterally from the top of the latching tongue piece 24 and has a suitably contoured protrusion, in the figure, a substantially rectangular contoured protrusion 25 and a top plate of the storage container 1. 5, the latching tongue piece 24 is folded with the non-return dispensing nozzle 4 inside, and the protruding piece 25 is formed in the notch 26, as shown in FIG. 5. When fitting and engaging are possible, there is an advantage that the storage container 1 can be manufactured inexpensively and easily without the need for an external member, attachment member, or the like for the storage container 1.
In this case, for example, by providing a notch 34 as shown in the drawing or a slit extending about 1 to 2 mm in a straight line from the bottom of the notch 26 to the through hole 20 side, The fitting into the notch 26 can be made easier.

When such a storage container 1 is made of paper, the thickness of the paper can be within a range of, for example, 250 to 500 g / m ² according to the internal volume of the package 10 or the like. When made of synthetic resin, for example, polypropylene, polyethylene, polyethylene, polyethylene terephthalate, nylon, ABS resin, polystyrene and the like can have a thickness of 0.3 to 3.0 mm.

FIG. 6 is a developed plan view of the storage container 1 that can be made of paper or synthetic resin. The storage container 1 cuts cardboard, for example, so as to include two

side plates

2 and 3 including the projecting piece 5 and a bottom wall constituting member 27 as shown in the figure, and also provides necessary tear induction. The

side plates

2, 3 are formed by folding the

side plates

2, 3. The lower end portions of the storage container 1 are joined to each other through the tongue piece 29, and the lower end of the storage container 1 is closed. For example, the flat portion forms a hexagonal bottom wall. A bottom plate 30 having a polygonal shape that closes the lower end of the storage container 1 is projected, and the bottom plate 30 is covered from the lower surface side to the lower end central side portion of the side plate 2 that is positioned to oppose the lower end central side portion. The presser bottom plate 31 to be stuck there, and the side plate 3 The end lateral side portions, also folded to overlap the bottom plate 30, is not bonded to either of the

bottom plate

30 and 31, projecting form a substantially triangular chevron corner protrusion 32.

In the figure, reference numeral 33 denotes folding pieces provided at the two corners on the front end side in the protruding direction of the polygonal bottom plate 30, and these folding pieces 33 are located at the positions of the mountain folding guide rods 34. 1 is formed together with the corner protrusion 32 so as to be bent toward the inner side of the container 1 and contact the lower end portion of the package 10 stored in the storage container 1 under frictional engagement with the inner surface of the container 1. It functions to prevent the package 10 from sticking out to the lower side of the bottom wall.
Accordingly, the bottom portions of the two

side plates

2 and 3 are separated from each other by a bottom wall that is formed between them and closes the lower end of the container 1, and the lower end portion of the container 1 has the shape of the bottom wall. The top of the container 1 forms two flat plates.
In addition, the outer contour shape of the intermediate portion between the lower end portion and the top portion of the storage container 1 has a curved shape that protrudes outward from the container 1 in the cross section.

Although the present invention has been described based on the illustrated examples, the planar contour shape of the bottom wall can be a required polygonal shape other than a hexagon, and the protruding piece 5 entrains the non-return dispensing nozzle 4. As long as it can be folded and deformed, it can have an appropriate form.
Further, the tear guide rod 8 having a curved shape as shown in the figure can be formed in a polygonal line shape.
