Description

  The present invention relates to a pouch for containing a refill shampoo, a liquid detergent and the like.

Conventionally, in Patent Document 1 shown below, as shown in FIG. 6, a rectangular overlapping sheet 51 is bonded by a side seal portion 52 along both side edges , and sealed along a lower edge, thereby accommodating space. 53, a refilling pouch in which a sealing portion 52 is curved on one side of the upper portion of the sheet 51 to provide a spout portion 54, and a cut line 55 is provided in the spout portion 54 is described.

The inner edge of the spout upper seal portion 56 that forms the upper edge of the spout portion 54 is inclined obliquely outward and upward starting from the lower end portion of the upper end drooping seal portion 57 that hangs from the upper end on one side of the sheet 51. It is said that.

  In this refill pouch, when the contents are transferred to the bottle, the sheet 51 is cut along the cut line 55, the spout 54 is opened, and the contents are moved forward (opposite the bottom). ).

  In addition to such refillable pouches, the spout is attached to the sheet as a spout, or a hollow tube is inserted into the spout, embossing to form a groove in the spout, etc. Refillable pouches that make it easier to pour out are known.

  However, in the refill pouch as described in Patent Document 1, when the contents are poured into the bottle, the contents may escape from the bottle and jump out. There is a problem that it takes. In addition, the contents cannot be completely transferred to the bottle, and the contents may remain in the refill pouch, resulting in waste.

  Accordingly, an object of the present invention is to provide a refill pouch that can easily and reliably refill the contents of the bottle into the bottle without performing special processing.

In order to solve the above-described problems, the present invention is configured such that overlapping sheets are bonded to each other at the side seal portion along both side edges and the lower seal portion along the lower edge, and inside the side seal portion and the lower seal portion . A storage space for the contents is formed, the side seal portion is curved so that the storage space protrudes on one side of the upper part of the seat, a spout portion is provided, and the content space is filled into the storage space with the upper end opened. In addition, the sheet is sealed by adhering the sheets together at the upper seal portion along the upper edge, the sheet is cut at the spout portion, and the refilling pouch that opens the spout portion is used to seal the accommodation space of the sheet. the inner edge of the sealing portion, note the slope provided toward the outlet side is downward, note the inner edge of the spout on the seal portion forming the upper edge of the outlet portion, inclined from an upper end connecting seal portion connected to the upper seal portion of the housing space is Shoulder that changes to become larger Through, it was formed an inductive edge pouring inclined over the distal end side of the spout obliquely out downward.

  In the refill pouch according to the present invention, when the content is poured into the bottle by opening the spout portion and opening the spout portion in a horizontal direction, the content smoothly changes direction at the shoulder portion, and the spout along the spout guide edge. The bottle is poured into the bottle along the axis of the spout, so it can be easily and reliably placed in the bottle without overflowing the contents while holding it with one hand, even without a spout. It can be transferred and the remaining amount of contents can be reduced as much as possible.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a state before filling the contents of the refill pouch according to the present invention. This refill pouch is bonded with a side seal portion 3 along both side edges in a state of sandwiching a sheet 2 in which the overlapping sheets 1 are folded at the bottom, and with a lower seal portion 4 along the lower edge. The bottoms are closed by bonding the sheets 1 and 2, and the content storage space 5 is formed inside the side seal part 3 and the lower seal part 4 .

On the upper one side of the sheet 1, a spout portion 6 is provided in which the side seal portion 3 is curved so that the accommodation space 5 protrudes and the inside is tapered.

On the inner edge of the spout upper seal portion 7 that forms the upper edge of the spout portion 6, a spout portion is provided via a shoulder portion 9 whose inclination changes from the upper end connection seal portion 8 facing the opening portion on the upper end side of the accommodation space 5. A pouring guide edge 10 inclined obliquely outward and downward is formed toward the tip end side of 6.

On the spout upper seal portion 7 above the spout portion 6, a knob 7 a is provided and a cut line 11 is formed along the spout guide edge 10.

  At the lower end portion of the score line 11, a cutting guide portion 11a that goes downward through the curved portion is provided, and at the upper portion of the score line 11, a connecting portion 11b that prevents unexpected breakage in the distribution process is provided. .

  Also, below the spout 6, a gripping constricted portion 12 is provided by constricting both side edges of the sheet 1.

The refilling pouch as described above is filled with contents such as shampoo and liquid detergent in the state where the upper end is open, and as shown in FIG. 2, the upper seal portion along the upper edge of the sheet 1 bonded at 13, in a state where its inner spout part 6 side is sealed to provide a gradient toward the downward and shipped to retailers.

  On the other hand, when the consumer transfers the contents of the refill pouch to the bottle, as shown in FIG. 3, the knob 11 a is twisted to cut the connecting portion 11 b and to extend the cutting guide portion 11 a. By cutting the sheet 1 along the line, the spout 6 is opened as shown in FIG.

  And as shown in FIG. 5, when the refill pouch is tilted in the horizontal direction, the opening of the spout 6 is inserted into the opening of the bottle B, and the constricted part 12 is gripped, the accommodation space 5 is narrowed, The contents of the storage space 5 are transferred to the bottle B.

At this time, the spout portion is formed so that the contents smoothly change direction from the upper end connection seal portion 8 connected to the upper seal portion 13 to the shoulder portion 9 and gather along the pouring guide edge 10 from the opposite side. 6 toward the center of the bottle 6 and poured into the bottle B along the axis of the spout 6 so that it can be easily and reliably transferred to the bottle B without overflowing the contents while holding the constricted part 12 with one hand. Can be replaced.

  In addition, there is no portion where the contents are likely to accumulate in the vicinity of the spout portion 6, and the amount of the contents remaining in the refill pouch can be reduced as much as possible, thereby eliminating waste.

  In the above-described embodiment, the standing pouch has been described as an example, but the same configuration can be adopted in the vicinity of the spout portion in other types of pouches such as a four-sided seal.
