As the 2nd base material 12, the same base material as the 1st base material 11 is mentioned, and a desirable mode is also the same.

  The male fitting portion 13 has a trunk portion 13a that rises from the facing surface 11a of the first base member 11, and a head portion 13b that is provided at the tip of the trunk portion 13a and has a substantially semicircular cross section larger than the trunk portion 13a. ing. The female fitting portion 14 includes a first arm portion 14a and a second arm portion 14b that rise in a cross-sectional arc shape from the facing surface 12a of the second base member 12, and the first arm portion 14a and the second arm portion 14b A recess 14c is formed by the two arm portions 14b. The male side fitting part 13 and the female side fitting part 14 can be detachably fitted by fitting the head part 13b of the male side fitting part 13 into the concave part 14c of the female side fitting part 14. ing.

The cross-sectional shape of the male side fitting part 13 and the female side fitting part 14 can repeat opening and closing of the opening part of a bag main body by attaching / detaching the male side fitting part 13 and the female side fitting part 14 mutually. Any known cross-sectional shape may be employed.
As the material of the male side fitting part 13 and the female side fitting part 14, the same material as the 1st base material 11 and the 2nd base material 12 can be used.

The inner rib 15 is provided along the longitudinal direction of the first base material 11 on the side end 11 b side of the opposing surface 11 a of the first base material 11 on the side end 11 b side. That is, the inner rib 15 is provided on the opening side of the male side fitting portion 13 in the facing surface 11 a of the first base material 11.
The inner rib 15 includes a rib main body portion 15a that rises from the facing surface 11a of the first base member 11, and a protrusion 15b that is formed on the male fitting portion 13 side of the rib main body portion 15a. Thus, the male side of the inner rib 15 is formed on the male fitting portion 13 side of the rib main body portion 15a of the inner rib 15 with the protruding portion 15b extending toward the male fitting portion 13 direction. It becomes easy to hook a finger on the fitting portion 13 side. Therefore, when both the opening end of the bag main body and the opening side of the first base material 11 are held together with the fitting 10 attached to the inner surface of the opening of the bag main body, the finger is difficult to slip and the bag is stable. The opening end of the main body and the first base material 11 can be gripped.

  The position of the protrusion 15b with respect to the rib main body 15a is preferably close to the tip of the rib main body 15a because it is easier to hook a finger, and from the male fitting portion 13 side of the tip of the rib main body 15a, It is particularly preferable that it is formed so as to extend in the male side fitting portion 13 direction.

The height d ₂ of the rib body portion 15a of the inner rib 15, the first opposing surface 11a and the second base material of the substrate 11 when fitted male engaging portion 13 and the female engaging section 14 It is preferably 0.2 times to 1.0 times, and more preferably 0.3 times to 0.9 times, with respect to the distance from the 12 opposing surfaces 12a. If the height d ₂ of the rib body portion 15a is more than the lower limit of the range, it becomes easy to hook the finger to the male side fitting portion 13 side of the inner rib 15, first an opening end of the bag body The base material 11 can be gripped more stably. Further, if the height d ₂ of the rib body portion 15a is more than the upper limit of the above range, fitting the male side of the inner rib 15 Put insert the fingers between the first substrate 11 second substrate It becomes easy to hook a finger to the joint portion 13 side, and the first base material 11 can be stably held together with the opening end of the bag body.

The length d _{1 of the} protrusion 15b (the distance from the base end to the tip of the protrusion 15b on the rib main body 15a side) is 0.1 to 0.6 times the height d ₂ of the rib main body 15a. Double is preferable, and 0.2 to 0.5 times is more preferable. If the length d ₁ of the protrusion 15b is more than the lower limit of the range, it becomes easy to hook the finger to the male side fitting portion 13 side of the inner ribs 15, the bag body open end with a first The substrate 11 can be gripped more stably. The length d ₁ of the protrusion 15b is not more than the upper limit of the range, when the hook finger projections 15b, slipping of the finger due to the protrusion 15b is bent is less likely to occur.

The cross-sectional shape of the rib main body portion 15a of the inner rib 15 is a trapezoidal shape in this example. However, the cross-sectional shape of the rib main body 15a is not particularly limited, and may be a triangular shape or the like. The width of the rib main body 15a is not particularly limited.
The cross-sectional shape of the protrusion 15b of the inner rib 15 is a square in this example. However, the cross-sectional shape of the protrusion 15b is not particularly limited, and may be a triangular shape or the like.
In addition, the cross-sectional shape of the rib main-body part 15a and the projection part 15b in the inner side rib 15 is a cross-sectional shape when the fitting tool 10 is cut | disconnected along a transversal direction. The same applies to the inner rib 16 and the outer ribs 17 and 18 described later.

The inner rib 16 is provided along the longitudinal direction of the second substrate 12 on the side end 12 b side of the opposing surface 12 a of the second substrate 12 with respect to the side end 12 b. That is, the inner rib 16 is provided on the opening side of the female side fitting portion 14 in the facing surface 12 a of the second base 12.
The inner rib 16 includes a rib main body portion 16a that rises from the facing surface 12a of the second base member 12, and a protrusion 16b that is formed on the female side fitting portion 14 side of the rib main body portion 16a. Thus, the protrusion 16b extending toward the female fitting portion 14 is formed on the female fitting portion 14 side of the rib main body portion 16a of the inner rib 16, so that the female side of the inner rib 16 is formed. It becomes easy to hook a finger on the fitting portion 14 side. Therefore, when the fitting tool 10 is attached to the inner surface of the opening of the bag body, when gripping both the opening end of the bag body and the opening side of the second base material 12, the finger is difficult to slip and the bag is stable. The opening end of the main body and the second substrate 12 can be gripped.

  The position of the protrusion 16b with respect to the rib main body 16a is preferably close to the tip of the rib main body 16a because the finger is more easily hooked, as in the case of the inner rib 15. It is particularly preferable that it is formed so as to extend from the female side fitting portion 14 side toward the female side fitting portion 14.

The height d ₄ of the rib main body portion 16 a of the inner rib 16 is the same as the height d ₂ of the rib main body portion 15 a of the inner rib 15, so that the male side fitting portion 13 and the female side fitting portion 14 are fitted. Is preferably 0.2 to 1.0 times, and preferably 0.3 to 0.9 times the distance between the facing surface 11a of the first substrate 11 and the facing surface 12a of the second substrate 12. Double is more preferred.
Further, the length d _{3 of the} protrusion 16b (the distance from the base end to the tip of the protrusion 16b on the rib main body 16a side) is the same as the length d ₁ of the protrusion 15b of the inner rib 15 for the rib main body. the height _{d 4} parts 16a, preferably 0.1 times to 0.6 times, more preferably 0.2 times to 0.5 times.

The cross-sectional shape of the rib main body portion 16a of the inner rib 16 is a trapezoidal shape in this example. However, the cross-sectional shape of the rib main body portion 16a is not particularly limited, and may be a triangular shape or the like. The width of the rib main body portion 16a is not particularly limited.
In this example, the cross-sectional shape of the protrusion 16b of the inner rib 16 is a square. However, the cross-sectional shape of the protrusion 16b is not particularly limited, and may be a triangular shape or the like.

The inner rib 15 and the inner rib 16 are preferably formed so that the positions of the first base material 11 and the second base material 12 in the short direction are shifted as in this example. Thereby, when opening the opening part of a bag body, a finger | toe can be hooked on the inner side rib 15 and the inner side rib 16 formed in the 1st base material 11 of the fitting 10, and the 2nd base material 12, respectively. It becomes easy.
Specifically, in this example, the length from the male fitting portion 13 to the side end 11b in the first base material 11 is from the female fitting portion 14 to the side end 12b in the second base material 12. The inner rib 15 and the inner rib 16 are provided in the vicinity of the side end 11b of the first base material 11 and the side end 12b of the second base material 12, respectively. The positions of the rib 15 and the inner rib 16 in the short direction are shifted.
When the inner rib 15 and the inner rib 16 are formed in this way, the inner rib 16 does not get in the way when the finger is hooked on the inner rib 15, so that it is easy to hook the finger on the inner rib 15. Further, since the finger can be hooked on the inner rib 16 with the hand holding the first base material 11 while the opening side of the first base material 11 is opened, it is easy to hook the finger on the inner rib 16. It is.
In addition, the aspect which provides the inner rib 15 and the inner rib 16 so that it may shift | deviate to a transversal direction is not limited to an above described aspect. For example, the length from the male fitting portion 13 to the side end 11b in the first base member 11 and the length from the female fitting portion 14 to the side end 12b in the second base member 12 are the same, You may provide the inner side rib 15 and the inner side rib 16 in the 1st base material 11 and the 2nd base material 12 so that each position may shift | deviate to a transversal direction.

  In the fitting 10, as described above, the length from the male fitting portion 13 to the side end 11 b in the first base material 11 is the side end from the female fitting portion 14 in the second base material 12. It is longer than the length up to 12b. Thereby, when the fitting tool 10 is attached to the bag body, a step is generated on the opening side of the first base material 11 and the second base material 12, so that the bag body is closed by the fitting tool 10. However, it becomes easy to grip the side end 11b side of the first base material 11. And the side end 11b side of the 1st base material 11 can be opened, and the side end 12b side of the 2nd base material 12 can be grasped easily. In this manner, by causing a step on the opening side of the first base material 11 and the second base material 12, the re-sealing of the bag body closed by the fitting tool 10 is further facilitated.

The inner rib 15 may be provided continuously along the longitudinal direction of the first substrate 11 or may be provided intermittently along the longitudinal direction of the first substrate 11 in a broken line shape. . It is preferable that the inner rib 15 is provided continuously along the longitudinal direction of the first base material 11 because it is easy to put a finger on the opening of the bag body and is excellent in opening performance. Similarly, even if the inner rib 16 is provided continuously along the longitudinal direction of the second substrate 12, it is provided intermittently along the longitudinal direction of the second substrate 12 in a broken line shape. Also good. It is preferable that it is provided continuously along the longitudinal direction of the second substrate 12 from the viewpoint that it is easy to put a finger on the opening of the bag body and is excellent in opening performance.
Further, the inner rib 15 may be provided in parallel with the male side fitting part 13 or may be provided to be inclined with respect to the male side fitting part 13. Similarly, the inner rib 16 may be provided in parallel to the female side fitting portion 14 or may be provided to be inclined with respect to the female side fitting portion 14.

  Moreover, although the number of the inner side ribs 15 and the inner side ribs 16 is one each in this example, it is not limited to this form. The number of the inner ribs 15 may be two or more. The number of the inner ribs 16 may also be two or more.

[Bag with fitting]
Hereinafter, the bag body 1 with a fitting tool provided with the fitting tool 10 mentioned above (henceforth "bag body 1") is demonstrated.
As shown in FIG. 2, the bag body 1 of the present embodiment has a sealed bag body 20 that accommodates contents and a fitting that is attached to the inner surface of the upper portion of the bag body 20 along the lateral direction. And a combination tool 10.
The bag main body 20 is formed by superimposing the first film material 21 and the second film material 22 and heat-sealing all the peripheral portions 23 thereof, and is in a sealed state. Moreover, the cutting auxiliary line 24 is provided in the upper side rather than the fitting tool 10 in the bag main body 20 along the horizontal direction, and the notch 25 is formed in the edge part.
As shown in FIG. 3, the outer surface 11 d of the first base material 11 of the fitting tool 10 is welded to the first film material 21 of the bag body 20, so that the fitting tool 10 has a second fitting tool 10. The outer surface 12 d of the base material 12 is welded to the second film material 22 of the bag body 20. In addition, the fitting 10 has the side end 11b and the side end 12b side of the first base material 11 and the second base material 12 on the opening side, and the side end of the first base material 11 and the second base material 12. 11c and the side edge 12c side are attached so that it may become the contents side.

As the cutting auxiliary line 24, for example, from a weakened line or a perforation in which the portion of the cutting auxiliary line 24 in the first film material 21 and the second film material 22 of the bag body 20 is thinner than the other parts. And weakening lines composed of pores formed in a row. Further, the cutting auxiliary line 24 is not limited to the weakening line, and may be a line formed by printing or the like indicating a position to be cut with a scissor or a cutter.
Although the cutting auxiliary line 24 is formed along the width direction of the bag body 20 in the present embodiment, the cutting auxiliary line 24 is not limited to this form, and may be provided inclined with respect to the width direction of the bag body 20. Good.

  The shape of the notch 25 is a triangular shape in this example, but is not particularly limited, and may be a semicircular shape, a linear shape, or the like.

The bag body 1 can be opened by forming an opening 26 in the upper portion as shown in FIG. 4 by cutting and removing the upper portion of the bag body 20 from the notch 25 along the cutting auxiliary line 24. . The opening 26 formed in the bag body 1 can be opened and closed repeatedly by attaching and detaching the male side fitting part 13 and the female side fitting part 14 of the fitting 10.

As shown in FIG. 6, the outer rib 18 can spread the opening end 22 a of the bag body 20 as shown in FIG. 6. Thereby, it can suppress that the opening ends 21a and 22a of the bag main body 20 contact | adhere in the state which closed the bag body with the fitting tool 10, and these opening ends 21a and 22a can be easily hold | gripped.

  In this example, the cross-sectional shape of the outer rib 18 is a trapezoidal shape. However, the cross-sectional shape of the outer rib 18 is not particularly limited, and may be a circular shape, a triangular shape, or the like. The height of the outer rib 18 may be a height that can sufficiently widen the open end in the state where the bag body is closed by the fitting tool 10. What is necessary is just to set suitably according to. The width of the outer rib 18 is not particularly limited.

The outer rib 18 is preferably located closer to the female fitting portion 14 than the inner rib 16 for the same reason as the outer rib 17. In addition, as shown in FIG. 7, the position of the short side direction of the outer side rib 18 and the inner side rib 16 may be the same.
The outer rib 18 may be provided continuously along the longitudinal direction of the second substrate 12 or may be provided intermittently along the longitudinal direction of the second substrate 12 in a broken line shape. .
