Considering the usability of the pouch with a spout, it is often preferable that the spout is disposed at the center in the width direction of the pouch body and is symmetrical in terms of weight balance. In that case, the penetrating through-hole cannot be disposed at the center in the width direction of the pouch body, and is disposed at a position shifted in the lateral direction. When the pouch with spout is suspended by using the suspension through-holes with such an arrangement, the pouch body tilts in front view. In that case, the display content of the display unit such as the front surface of the pouch body is also tilted, and it becomes difficult to visually recognize the display content of the display unit. If the display content of the display unit can be seen relatively naturally without tilting the display content of the display unit as much as possible, it is preferable in terms of high product appeal.
Moreover, in the suspension means which consists of a through-hole as described in Patent Document 1, there is a tendency that a fragment generated when the hole is punched is dropped into the housing portion of the pouch body. It is desired to prevent problems caused by fragments generated when drilled.

[First Embodiment]
Hereinafter, with reference to FIGS. 1-5, the pouch 1 with a spout of 1st Embodiment of this invention is demonstrated. FIG. 1 is a front view of a pouch 1 with a spout according to a first embodiment of the present invention. FIG. 2 is a partially enlarged view of FIG. 3, (A) is a cross-sectional view taken along line AA shown in FIG. 1, (B) is a cross-sectional view taken along line BB shown in FIG. 1, and (C) is a cross-sectional view taken along line CC shown in (B). It is sectional drawing. FIG. 4 is a perspective view showing the pouch 1 with a spout 1 in a suspended state. FIG. 5 is a front view showing the pouch 1 with a spout in a suspended state.

  As shown in FIGS. 1-3, the pouch 1 with a spout of 1st Embodiment is provided with the pouch main body 2, the spout 6, and the cut line 70 as a suspending means. The pouch 1 with a spout stores a fluid content in the pouch body 2 and can pour out the content stored in the pouch body 2 from the spout 6. Moreover, as shown in FIGS. 4 and 5, the pouch 1 with a spout can be suspended using a cut line 70. Each configuration will be described in detail below.

  In each drawing, the upper direction is indicated by D11, the lower direction is indicated by D12, and both directions are collectively referred to as “vertical direction D1”. The left direction is indicated by D21, the right direction is indicated by D22, and both directions are collectively referred to as “lateral direction D2.” The horizontal direction D2 is also the width direction D2 of the pouch body 2 and also the horizontal direction D2.

[Pouch body]
The pouch body 2 includes a content storage unit 26 (see FIG. 3) that stores fluid content. The content accommodated in the content accommodating part 26 will not be restrict | limited especially if it has fluidity | liquidity. Examples of the contents include beverages such as juices, fruit juices, jelly-like beverages, and nutritional drinks, liquid or powder seasonings, and other various foods and drinks. The contents include various daily necessities and medicines.

  As shown in FIGS. 1-3, the pouch main body 2 is comprised with a flexible film. The film constituting the pouch body 2 includes a front film 21 that forms the front surface, a back film 22 that forms the back surface, and a bottom film 23 that forms a gusset portion 34 of the bottom portion 32. The pouch body 2 has a bottom gusset pouch shape having a gusset portion 34 at the bottom 32. In other words, the pouch body 2 has a front surface formed by the front film 21, a back surface formed by the back film 22, and a bottom surface formed by the gusset portion 34 of the bottom portion 32. The pouch 1 with a spout functions as a standing pouch having independence.

  The front film 21 and the back film 22 are made of a substantially rectangular film. The substantially rectangular shape is not limited to a geometrical rectangular shape, and includes a shape that is recognized as a rectangular shape as a whole. For example, any one or more of the side edge, the bottom edge, and the top edge may include a curved portion. The corners of the film may be rounded in an outwardly convex arc shape.

  The gusset portion 34 is provided on the bottom portion 32 of the pouch body 2. When the content is stored in the content storage portion 26, the gusset portion 34 is sufficiently expanded as shown in FIGS. 3 (B) and 3 (C). Therefore, the pouch 1 with a spout can be independent. Moreover, since the gusset part 34 spreads, the volume of the content accommodating part 26 can be enlarged compared with the case of the flat pouch shape which does not equip a bottom with a gusset part. On the other hand, when no content is stored in the content storage portion 26, the bottom film 23 forming the gusset portion 34 can be folded back so that a folded portion is formed at the top. Thereby, the entire thickness of the pouch body 2 is reduced.

  In addition, this invention includes the pouch with a spout in the state in which the content is not accommodated, and the pouch with a spout in the state in which the content is accommodated.

  Further, the front film 21, the back film 22, and the bottom film 23 may be separate films from each other before the pouch body 2 is formed, or may be an integral film. In the case of an integral film, any two or more of the front film 21, the back film 22, and the bottom film 23 may be integral. The integral film is folded to form any two or more of the front film 21, the back film 22, and the bottom film 23.

  In the side part 33 of the pouch body 2, the side part 213 of the front film 21 and the side part 223 of the back film 22 are joined. Examples of the joining means include thermal welding (heat sealing) and ultrasonic welding (hereinafter the same). By this joining, side seal parts 50 and 50 are formed on the left and right side parts 33 of the pouch body 2 as seal parts for joining the side part 213 of the front film 21 and the side part 223 of the back film 22. The Details of the side seal portion 50 will be described later. In addition, the side part 33 of the pouch main body 2 is not provided with a gusset part.

Therefore, the pouch main body is formed before the spout attachment seal portion 40 is formed. 2 can form the spout attachment seal 40 so that the hot plate for heat welding does not hit the cut line 70, so that a sealant layer is formed from the cut line 70. It is possible to prevent the appearance of the thermoplastic resin that elutes from being eluted. Since the cut line 70 is arranged in the upper region 35 of the pouch body 2, the inclination of the display unit 24 is relatively small when the pouch 1 with spout is suspended using the cut line 70. Therefore, for example, in the product related to the pouch 1 with a spout, the display content of the display unit 24 can be visually recognized relatively naturally, and the appeal of the product is high. In addition, since no fragment is generated when drilled when forming the suspension means, it is possible to suppress problems caused by the fragment generated when drilled.

  In the pouch 1 with a spout of the first embodiment, the pouch body 2 has a substantially rectangular shape. Therefore, since the number of impositions can be increased with respect to the long front film 21 and the long rear film 22, the cost of the pouch body 2 can be suppressed.

  In the pouch 1 with a spout of the first embodiment, at least a part of the cut line 70 is disposed closer to the content container 26 than the inner edge 521 of the second side seal part 52. Therefore, the cut line 70 can be disposed one layer closer to the center of the pouch body 2 in the width direction D2.

[Modification of cut line]
In the first embodiment shown in FIG. 1 and the like, the cut line 70 is continuous. On the other hand, in the modification shown in FIG. 6, before the pouch 1 with spout is suspended, the cut line 70A has a substantially C-shape that is discontinuous with the discontinuous portion 75 in between. is there. The cut line 70A includes an arc-shaped first portion 71a having an inner end portion 72 and an outer end portion 73, an arc-shaped second portion 71b having an inner end portion 72 and an outer end portion 73, and a first portion 71a. A discontinuous portion 75 between the inner end 72 and the inner end 72 of the second portion 71b.

  The length W75 (see FIG. 6) of the discontinuous portion 75 is a length obtained by linearly measuring the opposed inner end portions 72, 72 of the cut line 70. The lower limit of the length W75 of the discontinuous portion 75 is, for example, 0.1 mm, preferably 0.2 mm, and more preferably 0.3 mm. The upper limit of the length W75 of the discontinuous portion 75 is, for example, 1.0 mm, preferably 0.9 mm, and more preferably 0.8 mm.

  As described above, the cut line 70A is discontinuous across the discontinuous portion 75, but is continuous when the discontinuous portion 75 breaks. The discontinuous portion 75 of the cut line 70A is broken, and a linking slit (not shown) is formed from the broken discontinuous portion 75, whereby the suspension hole 78 is formed.

  In the modification shown in FIG. 6, since the tongue piece 77 is not formed inside the cut line 70 </ b> A before the pouch 1 with spout is suspended, the tongue piece 77 is caught by the tongue piece 77 or the like. Can be prevented. On the other hand, if operation which suspends the pouch 1 with a spout is performed, 70 A of cut lines will continue by breaking the discontinuous part 75. FIG. Therefore, the pouch 1 with a spout can be easily suspended using the cut line 70A. Further, unintentional breakage of the inner portion of the cut line 70A from the pouch body 2 can be suppressed.

[Second Embodiment]
Next, a pouch 1A with a spout according to a second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a front view of a pouch 1A with a spout according to a second embodiment of the present invention (corresponding to FIG. 1). In the second embodiment, differences from the first embodiment will be mainly described. Therefore, detailed description of the same (or equivalent) configuration as in the first embodiment is omitted. Moreover, about the point which is not demonstrated especially in 2nd Embodiment, description of 1st Embodiment is applied or used suitably. In the second embodiment, the same effect as that of the first embodiment is achieved.

  In the pouch 1A with the spout of the second embodiment, the spout attachment seal portion 40 is provided over the entire width of the upper end portion 31 of the pouch body 2 as shown in FIG. That is, the overlapping portion 42 of the spout attachment seal portion 40 extends to the side edge of the pouch body 2. Therefore, the virtual extension portion 45 does not exist. In addition, the cut line 70 is always disposed below the overlapping portion 42 of the spout attachment seal portion 40. FIG. 7 shows an example in which the spout attachment seal portion 40 is formed so as to overlap with the first side seal portion 51, but the present invention is not limited thereto, and the first side seal is formed at the overlapping portion 42. Part or all of the part 51 may not be formed.

[Modification]
The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiments, and can be implemented in various forms. FIG. 8 is a partial cross-sectional view showing a flat pouch-shaped pouch body that does not have a gusset at the bottom (corresponding to FIG. 3C). The pouch body 2 in the above embodiment has a bottom gusset pouch shape having a gusset portion 34 at the bottom 32. On the other hand, as shown in FIG. 8, the pouch body 2 may have a flat pouch shape that does not include a gusset portion at the bottom portion 32.

The display unit 24 may be provided only on the back film 22.
The cut line 70 is not limited to a substantially C-shape, and can take various shapes as long as it can function as a hanging means.
The inner edge 513 of the first side seal portion 51 extends parallel to the vertical direction D1, but is not limited thereto. The inner edge of the first side seal portion 51 may extend obliquely upward toward the inside in the lateral direction D2. In other words, the inner edges of the pair of first side seal portions 51 in the lateral direction D2 may be inclined so that the interval gradually decreases toward the upward direction D11.
