  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view showing an example of a refilling pouch according to the present invention. This refilling pouch P is formed by combining a bottom part 2 folded in two between two wall-surface films forming a body part 1 in a vertically long shape. The so-called standing pouch is made into a bag. That is, a gusset-type bottom portion 2 in which the film is folded inward is provided with a semicircular cutout 2a in the vicinity of the lower ends on both sides, and is folded in two between two wall surface films forming the body portion 1. The refillable pouch P shown in FIG. 1 is made by sandwiching the bottom 2 and heat-sealing with a bottom-bottom-shaped bottom seal 3 and heat-sealing with a trunk seal 4 along the left and right edges.

  As shown in the figure, the refilling pouch P has a spout portion 10 whose periphery is heat-sealed at one of the upper corners of the bag. The spout portion 10 is provided between the notch 11 on the upper side and the notch 12 on the side so as to face obliquely upward. Of the notches 11 and 12, the notch 11 on the upper side has an acute angle V It has a letter shape. The spout portion 10 is provided with a planned opening portion 5 that crosses the portion near the front end in order to cut out the vicinity of the front end to form a spout, and one end thereof, that is, a notch on the upper side. A notch 6 is formed so as to be located in the direction of 11.

  As the planned opening portion 5 of the spout 10, the refillable pouch P is provided with the planned opening portion 5 formed of five half-cut lines formed by laser processing. Instead of laser processing, a planned opening portion 5 made of a half-cut line formed with a cutter such as a rotary die cutter may be provided, or a scheduled opening portion 5 may be provided by printing on the premise of cutting with scissors or the like. Also good. Further, by taking a method of laminating a uniaxially stretched film in a laminated film of a pouch (in this case, the uniaxially stretched film is used so that its stretching direction coincides with the planned opening portion 5), it is possible to improve the opening property. it can.

  And the part inside the opening opening part 5 of the spout part 10 becomes a two-stage shape combining the taper part 10a on the base side and the parallel part 10b on the opening part 5 side. The tapered portion 10a is tapered toward the tip, the angle α at which the extension of the taper inner seal line intersects is 50 to 80 °, and the parallel portion 10b of the spout portion 10 has an outer width. The width w on the outside when there is no content liquid is constant and substantially the same as the inner diameter of the bottle.

  The spout portion 10 is surrounded by an extension region of the body seal portion 4 by heat sealing, and the periphery is heat sealed. Such a spout portion 10 is heat-sealed so as to form a nozzle shape as shown in FIG. 1 on the extension of the body seal portion 4 when heat-sealing the two wall films on the front and back, and the periphery thereof is illustrated. It is formed by trimming to the shape.

  The refilling pouch P shown in FIG. 1 is in the form of a self-supporting stand pouch by filling with the content liquid and degassing and sealing the upper side seal portion 7. When the content liquid is transferred to the bottle, the tip of the spout 10 is sandwiched between fingertips and is torn from the notch 6 in the direction of the planned opening 5 to be opened. By this operation, the tip end portion of the spout portion 10 is removed, and a nozzle-shaped spout is formed.

  This refilling pouch P is formed with a spout, and then is held upside down by hand to insert the spout into the mouth of the bottle. Of the cutouts on both sides of the spout 10, the upper notch 11 has an acute angle. Since it is V-shaped, it can be easily inserted into the mouth of the bottle and the spout is prevented from being blocked.

  Further, the taper portion 10a on the base side of the spout portion 10 is tapered toward the tip, and the angle α at which the extension line of the inner seal line of the taper intersects is 50 to 80 °. The content liquid flows out vigorously as if it were a large-capacity funnel, and the discharge time can be shortened.

  Further, the parallel portion 10b on the front end side in the spout portion 10 has a constant outer width, and the outer width w when there is no content liquid is substantially the same as the inner diameter of the bottle. When the remaining amount is reduced, the parallel portion 10b is sized to fit the bottle mouth, the tip of the spout is held at the mouth of the bottle, and the spout can be prevented from coming out of the bottle.

  FIG. 2 is a front view showing a modification of the refillable pouch shown in FIG. In this refilling pouch P, a U-shaped recess 8 is provided near the base of the spout 10 so that the U-shaped opening o faces the spout 10. As shown in the enlarged sectional view of FIG. 3, the recess 8 is provided symmetrically so as to be recessed from the outside to the inside of the wall film F so as to be in the same position on the two wall films F facing each other. It has been. In addition, the recessed part 8 does not need to be U-shaped like illustration, and as shown in FIG. 4, the space | interval of a U-shaped linear part and a linear part spreads as it goes to the open part o of U-shape. It is good also as a shape, or as shown in FIG. 5, it is good also as two parallel linear form. Moreover, although the example which provides the recessed part 8 in the two wall film F was shown here, you may provide in any one wall film F.

  Since the refillable pouch P shown in FIG. 2 is provided so that the U-shaped concave portion 8 faces the open portion o toward the spout portion 10 from the vicinity of the base portion of the spout portion 10 toward the inside of the pouch. When the liquid is turned upside down with the content liquid contained, it is easy to maintain the opened state by encouraging the spout portion 10 to bend and spread in the vertical direction. The refilling pouch P shown in FIGS. 4 and 5 has the same effect, and the refilling pouch P provided with the recess 8 on one of the wall surface films F has the same effect, so which type is used. This may be determined appropriately depending on the material of the wall film F and the type of contents.

  FIG. 6 is a front view showing a further modification of the refillable pouch shown in FIG. In this refilling pouch P, in addition to the concave portion 8 described with reference to FIG. 2, an elliptical convex portion 9 is provided at the spout portion 10 so as to intersect with the planned opening portion 5. As shown in the enlarged cross-sectional view of FIG. 7, the convex portion 9 has a symmetrical shape so as to be recessed from the inner side to the outer side of the wall surface film F so as to be in the same position on the two opposing wall surface films F. Is provided. Although the example which provides the convex part 9 in the two wall film F was shown here, you may provide in any one wall film F. FIG.

  When the refilling pouch P shown in FIG. 6 is turned upside down, it is easy to maintain the open state by encouraging the spout portion 10 to bend and spread in the vertical direction by the recess 9. In addition, since the convex portion 8 is provided at the planned opening portion 5 of the spout portion 10, the opening can be enlarged.

  The film used in the refill pouch of the present invention is a laminated film mainly composed of a plastic film, and a laminated film having a heat seal layer on the inner surface is mainly used, but is not particularly limited. Any known laminated film used in liquid pouches can be used. From these, a suitable one may be selected and used according to the use conditions such as the type of the content liquid and the presence or absence of heat treatment after filling.

[Shape comparison test]
In order to confirm the effectiveness of the present invention, a comparative test was performed under the following conditions.

<Used laminated film>
ONY (15 μm) / Printing / DL / PEF (130 μm)
ONY: “ON-RT” made by Unitika
PEF: Techno film "SP-303SL"
Printing ink: "CLIOS" made by The Inktec
Adhesive: "RU-77T / H7" manufactured by Rock Paint

  Using the laminated film described above, heat sealing, laser processing, and punching were sequentially performed to form a pouch P of the type shown in FIG. Here, the size of the pouch P: 230 mm in length × 120 mm in width, the width of the body seal part 4: 6 mm, the width of the upper seal part 6: 10 mm, the seal width of the spout part 10: 3 to 4 mm, the notch 11 on the upper side The vertical seal width is 5 mm, the outer width w of the parallel portion 10 b of the spout portion 10 is 19 mm, and the angle α (“taper angle” at which the extension of the taper inner seal line in the tapered portion 10 a of the spout portion 10 intersects. )) And made a variety of pouches.

  Then, each pouch P was filled with a general-purpose liquid detergent (350 ml) as a content liquid, and a pouring test into a bottle (caliber 20 mmφ) was performed. In addition, a general-purpose liquid detergent is “ofuro look (registered trademark)”, which is a surfactant (5%, sodium linear alkylbenzene sulfonate) to which a foam modifier and a chelating agent are added.

  During the pouring test, the spout 10 was broken at the half-cut line 5 to form a spout. Then, the bottle was placed on the desk, the pouch P was turned upside down, and the spout was inserted into the mouth of the bottle to refill the content liquid. At the time of refilling, the pouch was not pushed, the liquid was poured out only by its own weight discharge, and the time from when the content liquid started to break was measured. In addition, the impression of ease of refilling the bottle and the stability when inserted into the bottle mouth were also evaluated.

  Based on the evaluation criteria shown in Table 1, the evaluation of the dispensing test was evaluated in five stages for each of the two conditions of insertion stability and discharge time. The test results are shown in Table 2.

  The commercially available in-house product used in Comparative Example 4 is shown in FIG. 8, and the same parts as those in FIG. This refilling pouch (internal capacity: 350 ml) has a pouch size: 230 mm long × 120 mm wide, body seal part 4 width: 6 mm, upper seal part 6 width: 10 mm, upper side notch 11 seal width: 4 mm, longitudinal seal width of the notch 11 on the upper side: 4 mm, seal width of the notch 12 on the side side: 3 mm, nozzle angle β of the spout portion 10: 10 °, width of the spout tip: 19 mm, after opening Nozzle length: 15 mm.

  The refillable pouch of Comparative Example 4 is provided with convex portions 9 on both sides of the bisector of the spout portion 10 from the spout portion 10 to the vicinity of the center of the bag, thereby increasing the rigidity of the spout portion 10. In addition, since the taper angle of the spout portion 10 is small, it is difficult to bend the spout portion 10 so as to be bent in the vertical direction, and the spout portion 10 cannot be poured out in a short time.

  As can be seen from Table 2, in terms of discharge time, the taper angle α in the range of 50 to 80 ° as in Examples 1 to 6 was evaluated well. On the other hand, when the taper angle α is less than 50 ° as in Comparative Examples 1 and 2, or when the taper angle α exceeds 80 ° as in Comparative Example 3, the spout is blocked. It was difficult to pour the content liquid into the bottle.

  As mentioned above, although the form for implementing this invention has been demonstrated in detail, the refilling pouch by this invention is not limited to said embodiment at all, and various in the range which does not deviate from the meaning of this invention. Of course, changes are possible.
