In the figure, reference numeral 1 denotes a spouting device. The spouting device 1 is formed into a packaging container A in which a front sheet and a back sheet are overlapped and a peripheral portion is heat-sealed with a bottom sheet interposed on the container bottom side. It is attached so as to straddle the upper side B of the packaging container A (see FIG. 2). Spout 1 as shown
Is connected to the first opposing plate 2 and the second opposing plate 3 via a linear folding part 5 in which two self-hinges 4 are arranged in parallel. The two opposing plates 3 are provided so as to be folded, and the opposing plates 2 and 3 are brought into contact with the sheet of the liquid container A by folding the folded portion 5 against the upper side B. is there.
The folded portion 5 may have a certain width at a thin portion of the single self-hinge 4.

[0007] As shown in the figure, the first opposing plate 2 has a pouring cylinder 6 projecting toward the side opposite to the second opposing plate 3 when folded, that is, outwardly. In the other second opposing plate 3, by being bulged in a substantially dome shape toward the opposite side to the first opposing plate 2 when folded, that is, outwardly, it is dented. It has a storage part 7 formed, and the storage part 7 is located at a position corresponding to the pouring cylinder 6 when folded to the first opposing plate 2. Further, each of the first opposing plate 2 and the second opposing plate 3 is provided with a second folded portion 9 composed of a self hinge 8 at a lower edge position of the upper side B of the packaging container A as shown in FIG. Each of the second folded portions 9 can be folded back in the opposite direction to the folded portion 5.

In FIG. 1, reference numeral 10 denotes an adhesive means, which is an area around at least the position of the second folded portion 9 around the pouring cylinder and around the storage portion on the facing surfaces 2a, 3a of the first facing plate 2 and the second facing plate 3. In the illustrated embodiment, it is provided on the opposing surface 2a excluding the pouring cylinder 6 and on the opposing surface 3a excluding the storage unit 7. The bonding means 10 is bonded in advance to each of the opposing surfaces 2a, 3a, and is protected by a release paper 11 when not in use. This bonding means 10
Is made of, for example, a double-sided adhesive tape.
When attaching the spout 1 to the packaging container A, the protective release paper 11 is peeled off. Since the bonding means 10 is arranged at least around the pouring cylinder 6 and the storage section 7, the first opposing plate 2 and the second opposing plate 3 are attached to the sheet C of the packaging container A via the bonding means 10. And the internal space of the pouring cylinder 6 does not continue to the outside through the gap between the sheet C and the first opposing plate 2, and the storage portion 7 has the gap between the sheet C and the second opposing plate 3. The contents do not leak to the outside through the sheet C and the spout 1 even when the contents described below are poured out.

FIG. 3 is a sectional view showing a state in which the spout 1 is attached so as to straddle the upper side B of the packaging container A via the bonding means 10.
The first opposing plate 2 is attached to, for example, a sheet C serving as a front sheet, while the second opposing plate 3 is attached to a sheet C serving as a back sheet, while being applied to the upper end of the sheet. And, as described above, since the second folded portion 9 is positioned so as to correspond to the lower edge of the upper side B, for example, the position between the front sheet and the back sheet at the position where the spout 1 is attached Even when there is an increase in the internal pressure that spreads except for the upper side, each of the first opposing plate 2 and the second opposing plate 3 rotates outward from the second folded portion 9, respectively. There is no restriction on the movement of each of the seat and the back sheet to bulge outward. As a result, a space in which the contents flow between the front sheet and the back sheet is reliably ensured, and the contents, which are opened by piercing as described later, are poured out through the spout cylinder and the cap. There is no trouble.

The second opposing plate 3 has a curved holding piece 24 which is continuous with the upper and lower ends of both sides facing each other in a direction orthogonal to the direction of connection with the first opposing plate 2, and is shown in the drawing. As described above, the small holding piece 25 is protruded from the side of the second opposing plate 3 so as to protrude into the opening area formed between the holding piece 24 and the side of the second opposing plate 3. Folded part 26
The spout 1 is inserted into the packaging container A
The small holding pieces 25 are provided on the first opposing plate 2 side in a state where the small holding pieces 25 are elastically rotatable. Since the small holding piece 25 is rotatable toward the first opposing plate 2 in this manner, the holding piece 24 is closer to the opening 27 between the holding piece 24 and the small holding piece 25. When the spout 1 is attached to the center of the upper side B of the packaging container A as shown in FIG. If both ends D of the upper side B of A are folded back to the second opposing plate 3 side and then inserted into the opening 27, the folded side ends D become the holding pieces 24 and the small holding pieces 25. And will be held. If the both end portions D are held in a folded state in this manner, when the contents are poured out, the contents hardly flow into the internal space corresponding to the both end portions D, and the spout device It is possible to guide the contents so as to concentrate on the space at the position where 1 is attached.

In the above embodiment, an example is shown in which the piercing member 12 is pushed into the spouting cylinder 6 by rotation, but the present invention is not limited to this. For example, as shown in FIG. 7, it is assumed that the cap 17 is slidably mounted on the dispensing cylinder 6, and the cap 17 is dispensed so as not to be inadvertently moved to the packaging container A when not in use or when not in use after opening. It is possible to adopt a structure in which a spacer 28 is detachably mounted on the base side of the cylinder 6. In this structure, by removing and pushing in the spacer 28, the sheet C is pierced and opened by the piercing member 12, and then the cap 17 is pulled out and the needle portion 13 of the piercing member 12 is engaged with the opening end of the ejection tube 6. , The cap 17 stops, and the contents can be poured out.
7 is pushed in to close the through hole 15 of the locking disk 14 so that the pouring cylinder 6 can be closed.

FIGS. 8 and 9 show another example. In the above-described embodiment, the piercing member 12 is disposed on the pouring cylinder 6, but in the examples shown in FIGS. 8 and 9, the piercing member 12 is disposed on the second opposing plate 3, and the first opposing plate is provided. 2, the piercing member 12 is positioned so as to correspond to the pouring tube 6, and is provided so as to protrude toward the pouring tube 6. In the example shown in FIG. 8, the second opposing plate 3 projects toward the opposite side to the first opposing plate 2 side when it is superimposed on the first opposing plate 2 side, that is, projects outward. The piercing member 12 is attached to the storage portion 7 so that the needle portion 13 is positioned inside the storage portion 7, and is stored in the outer bridge of the piercing member 12. The outer side of the portion 7 is closed, and the piercing member 12 is provided so that it can be pushed into the sheet C from a state where the piercing member 12 does not contact the sheet C,
When the piercing member 12 is pushed in, both sheets C, that is, the back sheet and the front sheet are pierced and opened. For example, the stab member 12 may be pushed in such a manner that the stab member 12 is slidable with respect to the storage section 7, and the outer end of the stab member 12 covers the storage section 7 as illustrated. The flange 29 can be slid in contact with the outer periphery of the storage portion 7 so that the flange 29 can be pushed toward the pouring tube 6 in a state where the flange 29 is in contact with the storage portion 7. In this case, when the sheet C is not opened, the piercing member 1 is inadvertently inserted.
Provisional positioning means may be provided so that 2 does not slide to the pouring cylinder 6 side. For example, a projection 30 is provided at a position to be temporarily fixed on the outer periphery of the storage section 7 and the piercing member 12 is consciously pierced. Pressing the flange 29
Over the projection 30.

As another example of the pushing-in structure of the piercing member 12, the needle portion 13 of the piercing member 12 and the flange 29 are screwed to the storage portion 7 and the piercing member 12 is rotated by screwing. It is also possible to be pushed out to the side. FIG. 9 shows still another example, in which the piercing member 12 in which the needle portion 13 is located inside the storage portion 7 is connected to the connecting plate 31 which is annularly formed at the outer end of the storage portion 7 and is elastically deformable. The connection plate 31 has a structure in which the outer periphery is continuous with the outer end of the storage portion 7 and the inner periphery is continuous with the piercing member 12, whereby the inner space of the storage portion 7 is closed to the outside. And in this example, the connecting plate 31
The elastic deformation of the connecting plate 31 allows the connecting plate 31 to be deformed from a state in which the connecting plate 31 protrudes from the storage tube portion 7 to a state in which the connecting plate 31 enters the inside of the storing portion 7. When the piercing member 12 is pushed in, the needle portion 13 moves toward the pouring cylinder 6 to pierce and open the sheet C.

In the example shown in FIGS. 8 and 9, a piercing member 12 is provided on the second opposing plate 3, and the piercing member 6 is pushed by the second opposing plate 3 to correspond to the discharging tube 6. Since the sheet C is opened, the piercing member such as the examples shown in FIGS. As shown in FIG. 8, the pouring cylinder 6 is provided with a closing rod 32 protruding outward from the inside thereof, and when the cap 17 moves to the packaging container A side, A structure in which the closing rod 32 is separated from the pouring hole 18 to be opened by fitting the pouring cylinder 6 into the pouring hole 18 of the cap 17 and moving the cap 17 outward, so that the contents can be poured. Can be adopted. The structure for opening and closing the dispensing cylinder 6 is not limited to this example, and may be a hinge cap type, a toggle cap type, or a polytop cap type. You may do so.

Although the spout 1 has been described as being mountable on the upper side B of the packaging container A, the mounting position is not limited. For example, as shown in FIG. 10, in a packaging container A having a standing pouch structure, the spout 1 may be attached from the front sheet to the bottom sheet. In this case, it is assumed that the second opposing plate 3 located on the bottom sheet side has no holding piece or small holding piece.
