Description

  The present invention relates to a refill packaging bag for hermetically sealing a fluid content.

  Conventionally, containers such as bottles that are used in a state in which fluid contents are contained are used continuously after the contained contents are used up, so the contents for refilling are sealed and packaged. Refill packaging bags are used.

  The refill packaging bag is generally composed of a pair of front and back side sheets and a bottom sheet sandwiched between the bottom and the bottom, and these edges are heat sealed in a bag shape. In this type of refill packaging bag, a discharge port for discharging the contents is provided at the upper corner for workability when transferring the contents to a container such as a bottle. As the discharge port, one formed by attaching a spout as a separate member is known, but is expensive.

(See Patent Document 1).

JP 2006-117263 A

  As described above, a refill packaging bag in which the discharge port is formed by cutting and removing the tip of the discharge port is often used for hermetically wrapping shampoo or the like as the contents, and is relatively large. Of capacity. When this type of refill packaging bag is to be applied to a small-capacity bag, the contents cannot be discharged well if the conventional shape is reduced as it is. This is because a large-capacity refill packaging bag is designed in a shape suitable for its size, and if it is attempted to reduce the size as it is, the discharge port becomes narrow and discharge defects are likely to occur. . However, if the discharge port is widened, the discharge port portion becomes large, and it becomes difficult to insert it into the mouth portion of a container such as a bottle. In particular, when a container such as a bottle has a small capacity, the mouth portion is also small, so that the contents are easily spilled out of the container.

  The present invention has been made in view of these problems, and even with a small-capacity design, the discharge port portion can be easily inserted into the mouth portion of a container such as a bottle, and the contents can be discharged well. The object is to provide a refillable packaging bag.

  The refill packaging bag according to claim 1, which achieves the above-mentioned object, comprises a pair of front and back side sheets, and seals the fluid contents by sealing the edges of the bags in a bag shape, A discharge port for discharging the contents is formed by cutting and removing the tip of the discharge port portion protruding at the corner portion along the cutting line.

  And in this packaging bag for refilling, the 1st inner side line which is an inner side line of one seal part is indented inside among the seal parts of both sides which sandwich the discharge mouth in the state where the tip of the discharge mouth part was cut and removed. The second inner line, which is an inner line of the other seal portion, is formed in a straight line, and is an extension of the second inner line and a first that passes through the midpoint of the discharge port on the cutting line. The tangent of the inner line intersects at an angle of 60 to 75 ° outside the discharge port.

According to such a packaging bag for refilling, since the first inner line is formed in a shape recessed inward, the discharge port portion can be easily inserted into the mouth portion of a container such as a bottle.
And since the 2nd inner side line is formed in linear form, the swelling shape of the side sheet at the time of discharging the contents from a discharge outlet can be stabilized. That is, when the content is discharged from the discharge port, the content gathers in the vicinity of the discharge port, so that the vicinity of the discharge port has a shape swelled in three dimensions so that the side sheets are separated from each other. However, since the edge part of the side sheet is sealed in a bag shape, the side sheets are close to each other in the vicinity of the seal part, and the opening area of the discharge port is reduced depending on the bulge shape. Although this bulge shape can be changed depending on the compression position when the side sheet is compressed with a finger, the second inner line is formed in a straight line in the refill packaging bag according to claim 1. The swollen shape can be stabilized as compared to other shapes.

  In addition, the angle at which the extended line of the second inner line and the tangent of the first inner line passing through the midpoint of the discharge port on the cutting line intersect at the outside of the discharge port is 60 ° or more, The discharge port portion is made easy to be inserted into the mouth portion of a container such as a bottle by making the material easy to discharge well and at 75 ° or less.

  Therefore, according to the packaging bag for refill according to claim 1, even if the design is a small capacity, the discharge port portion can be easily inserted into the mouth portion of a container such as a bottle and the contents can be discharged well. be able to.

  Further, for example, the refill packaging bag according to claim 2 is the refill packaging bag according to claim 1, wherein a distance between the cutting line and a tangent of the first inner line parallel to the cutting line is set. 5.5 to 7.5 mm. If this distance is too short, it becomes difficult to insert the discharge port portion into the mouth portion of a container such as a bottle, and conversely, if this distance is too long, the contents are difficult to be discharged from the discharge port. According to this packaging bag for refilling, it is possible to discharge the contents satisfactorily while making it easy to insert the discharge port portion into the mouth portion of a container such as a bottle.

  Further, for example, in the refill packaging bag according to claim 3, the refill packaging bag according to claim 1 or 2, wherein the side sheet seal is connected to the seal portion forming the first inner line. The third inner line, which is the inner line of the part, is formed in a straight line, and the indentation depth of the first inner line with respect to the third inner line is 4 to 8 mm. If the indentation depth is too shallow, it will be difficult to insert the discharge port into the mouth of a container such as a bottle, and conversely, if the indentation depth is too deep, it will be difficult for the contents to be discharged from the discharge port. According to the refill packaging bag described in Item 3, the contents can be discharged well while making it easy to insert the discharge port portion into the mouth portion of a container such as a bottle.

It is a front view of the pouch for refilling of 2nd Embodiment. It is the elements on larger scale which expanded the part in which the discharge outlet part of 2nd Embodiment was formed.

Embodiments to which the present invention is applied will be described below with reference to the drawings.
[First Embodiment]
FIG. 1 is a front view of a refill pouch 100 as a refill packaging bag according to the first embodiment. This refilling pouch 100 is for sealing and packaging a refilling lotion for transfer to a small-capacity bottle (not shown) containing a lotion, and has a small volume (50 to 300 ml). The internal volume is about 140 ml in this embodiment. The refill pouch 100 is designed to have a vertical dimension of 180 mm and a horizontal dimension of 91.5 mm.

  The refill pouch 100 includes a pair of front and back side sheets 11 and 12 having a substantially rectangular shape and a bottom sheet 13 sandwiched between the bottom sheet 13 and the lower part thereof, and the edges thereof are heat-sealed in a bag shape. . Specifically, both side portions of the side sheets 11 and 12 are formed in a straight line along the vertical direction (vertical direction), and heat sealing is performed with the seal portions 21 and 22 having a constant width (5 mm in the present embodiment). Has been. The lower portions of the side sheets 11 and 12 are heat-sealed with the bottom sheet 13 by a ship-bottom-shaped seal portion 23 that is concave in a curved line shape from both sides to the center.

  Further, at one corner (on the left side in FIG. 1) of the upper part of the side sheets 11 and 12, notches 31 and 32 are provided on the side and upper sides in the vicinity of the corner, respectively, so that the discharge projecting obliquely upward. An outlet portion 30 is formed. Among these, the notch 31 provided on the side of the side sheets 11 and 12 (the lower part of the discharge port portion 30) has an approximately V shape in which the upper angle (angle with respect to the side) is steep and the lower angle is gentle. It is formed in a shape.

FIG. 2 is a partially enlarged view in which a portion where the discharge port portion 30 is formed is enlarged.
In this refilling pouch 100, the discharge port for discharging the contents (skin lotion) is formed by cutting and removing the tip of the discharge port part 30 along the cutting line 33. The first inner line 41A, which is the inner line of the lower seal portion 41, of the seal portions 41 and 42 on both sides sandwiching the discharge port in a state where the tip is cut and removed, is formed in an inwardly recessed shape. ing. On the other hand, the second inner line 42A, which is the inner line of the upper seal portion 42, is formed in a straight line extending in the horizontal direction (the horizontal direction orthogonal to the vertical direction).

  Further, the seal portion 42 is formed with a notch 42B serving as a starting point for cutting the tip of the discharge port portion 30. Further, although not shown, the refill pouch 100 has a cut line extending from the notch 42B printed on the outer surface, and the user cuts the cut line using the cut line as a guideline. 30 tips are cut off.

  In the state where the tip of the discharge port portion 30 is cut and removed, the width of the discharge port formed is preferably in the range of 4 to 15 mm, and in this embodiment, the width is designed to be 8 mm. In addition, the outer width of the discharge port portion 30 (the width of the discharge port + the width of the seal portions 41 and 42) in a state where the tip is cut and removed is equal to or smaller than the diameter of the bottle port, It is designed to be more than the value obtained by subtracting 2 mm from the diameter. That is, it is designed so that the relationship of “the width of the discharge port + the width of the seal portions 41 and 42” ≦ “the diameter of the bottle port portion” ≦ “the width of the discharge port + the width of the seal portions 41 and 42 + 2 mm” is satisfied. .

  Further, the angle θ1 at which the extension line of the second inner line 42A and the tangent line of the first inner line 41A passing through the midpoint P1 of the discharge port on the cutting line 33 intersect outside the discharge port is 60 to 75 °. It is designed within the range.

The distance L1 between the cutting line 33 and the tangent line of the first inner line 41A parallel to the cutting line 33 is designed to be in the range of 5.5 to 7.5 mm.
Moreover, the 3rd inner side line 21A which is an inner side line of the seal | sticker part 21 of the left side part of the side sheets 11 and 12 connected to the lower seal part 41 of the discharge port is formed in a straight line shape, and the third inner line 21A The indentation depth L2 of the first inner line 41A is designed within a range of 4 to 8 mm.

  A portion of the upper portion of the refill pouch 100 where the discharge port portion 30 is not provided is sealed by heat sealing with the seal portion 24, but this portion is used as a filling port for contents. The opening is unsealed before filling the contents, and is heat-sealed after filling the contents. The fourth inner line 24A, which is the inner line of the seal portion 24, is formed in a straight line, but is preferably formed so as to be aligned with the second inner line 42A.

  According to the first embodiment described above, since the lower side of the discharge port is formed in a shape recessed inside by the notch 31, the discharge port portion 30 in a state where the tip is cut and removed is used as the mouth portion of the bottle. It can be easily inserted. In particular, the notch 31 is formed in a substantially V shape in which the angle near the discharge port is steep and the angle far from the discharge port is gentle, and the first inner line 41A is also formed in the same shape. Therefore, the discharge port 30 can be easily inserted into the mouth of the bottle while preventing the flow of the contents (skin lotion) along the first inner line 41A from being obstructed.

  In addition, since the second inner line 42A on the upper side of the discharge port is formed in a straight line, the bulging shape of the side sheets 11 and 12 when the contents are discharged from the discharge port can be stabilized. That is, when the contents are discharged from the discharge port, the contents gather in the vicinity of the discharge port, so that the vicinity of the discharge port has a three-dimensionally swollen shape so that the side sheets 11 and 12 are separated from each other. However, since the edge portions of the side sheets 11 and 12 are heat-sealed in a bag shape, the side sheets 11 and 12 are close to each other in the vicinity of the seal portion, and the opening area of the discharge port is small depending on the bulging shape. turn into. This bulge shape can be changed depending on the compression position when the side sheets 11 and 12 are compressed with a finger, but the refill pouch 100 has a second inner line 42A formed in a straight line. The swollen shape can be stabilized as compared with the shape.

  In addition, the angle θ1 at which the extended line of the second inner line 42A and the tangent of the first inner line 41A passing through the midpoint P1 of the discharge port on the cutting line 33 intersect outside the discharge port is 60 ° or more. By doing so, it is easy to insert the discharge port part 30 in a state where the tip is cut and removed into the mouth part of the bottle by making it 75 ° or less while facilitating the easy discharge of the contents.

  Further, the distance L1 between the cutting line 33 and the tangent line of the first inner line 41A parallel to the cutting line 33 is set to 5.5 mm or more, so that the discharge port portion 30 in a state where the tip is cut and removed can be removed. By making the distance L1 7.5 mm or less while facilitating insertion into the mouth, the contents can be easily discharged well.

  Furthermore, by making the indentation depth L2 of the first inner line 41A with respect to the third inner line 21A to be 4 mm or more, the indentation is made while making it easy to insert the discharge port portion 30 with the tip cut and removed into the mouth portion of the bottle. By setting the depth L2 to 8 mm or less, the contents can be easily discharged easily.

  Therefore, according to this refilling pouch 100, even in a small capacity design, the discharge port 30 can be easily inserted into the mouth of the bottle, and the contents can be discharged well while preventing the bottle from spilling. can do.

  On the other hand, the discharge port portion 30 of the refilling pouch 100 includes “the width of the discharge port + the width of the seal portions 41, 42” ≦ “the diameter of the bottle port portion” ≦ “the width of the discharge port + the width of the seal portions 41, 42”. Since the relationship of “width + 2 mm” is established, the discharge port portion 30 can be directly inserted into the mouth portion of the bottle without being bent. For this reason, there is no effort to bend the discharge port portion 30, and it is possible to prevent insufficient opening of the discharge port due to bending.

  In addition, since the discharge port portion 30 of the refill pouch 100 is not embossed, the contents can be prevented from spilling when the refill pouch 100 is tilted. In particular, since the lotion, which is the content of the present embodiment, has a low viscosity, if the discharge port is easily opened by embossing, the content spills out before the discharge port 30 is inserted into the mouth of the bottle. It is possible to end up. In this respect, in the refilling pouch 100 of the present embodiment, the spillage of the contents can be suppressed as compared with the embossed one.
