[Fitting tool]
Hereinafter, an example of the fitting tool of the present invention will be shown and described in detail. FIG. 1 is a cross-sectional view of a fitting 10 that is an example of the fitting of the present invention cut perpendicularly to the longitudinal direction.
The fitting tool 10 has a pair of belt-like first base material 11 and second base material 12 and the opposing surfaces 11a and 12a of the first base material 11 and the second base material 12 in the longitudinal direction. It has the male side fitting part 13 and the female side fitting part 14 which were provided along. The male side fitting part 13 and the female side fitting part 14 can be detachably fitted to each other.

The 1st base material 11 is not specifically limited, What is used for the base material of a well-known fitting tool can be used, and the base material which consists of laminated films is preferable. As the 1st base material 11 which consists of laminated films, the film by which the heat resistant layer and the heat seal layer were laminated | stacked from the opposing surface 11a side is mentioned, for example. The first substrate 11 may have a barrier layer between the heat-resistant layer and the heat seal layer.
Examples of the material for the heat-resistant layer include biaxially stretched nylon and biaxially stretched polypropylene.
Examples of the material for the heat seal layer include linear low density polyethylene, unstretched polypropylene, ethylene-vinyl acetate copolymer, and ionomer.
Examples of the material for the barrier layer include polyvinyl alcohol.

The 1st base material 11 may consist of 1 type of resin, and may consist of the resin composition containing 2 or more types of resin. Moreover, well-known additives, such as a stabilizer, antioxidant, a lubricant, an antistatic agent, and a coloring agent, may be added as needed.
Moreover, the 1st base material 11 is not limited to the base material which consists of laminated films, The base material which consists of a single layer film may be sufficient.
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.

As shown in FIGS. 1 and 2, the male-side fitting portion 13 is provided on the trunk portion 13 a rising from the facing surface 11 a of the first base material 11, and on the distal end side of the trunk portion 13 a, and has a larger head than the trunk portion 13 a 13b. Moreover, the male side fitting part 13 has one concave strip 13c formed along the longitudinal direction on the distal end side of the head portion 13b, and the portion on the distal end side of the trunk portion 13a from the head portion 13b is formed by the concave strip 13c. Branched. That is, the male side fitting part 13 has a shape that is divided into two forks from the middle of the trunk part 13a to the tip of the head part 13b by the recess 13c.
The female-side fitting portion 14 includes a pair of first arm portion 14a and second arm portion 14b that rise in a circular 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.

Since the fitting tool 10 has a bifurcated shape from the middle of the trunk portion 13a to the tip of the head portion 13b in the male fitting portion 13, the male fitting portion 13 and the female fitting portion 14 are connected to each other. When fitting, a better feeling of fitting than a conventional fitting can be obtained. This is considered as follows.
As shown in FIG. 3, when the head portion 13 b of the male fitting portion 13 is fitted into the concave portion 14 c of the female fitting portion 14, the first arm portion 14 a and the second arm of the female fitting portion 14. While the portion 14b is pushed open, the bifurcated portion on the head 13b side of the male fitting portion 13 is inwardly formed by the first arm portion 14a and the second arm portion 14b of the female fitting portion 14. It is pushed down. When the head portion 13b of the male fitting portion 13 is fitted into the recess 14c of the female fitting portion 14, the first arm portion 14a and the first arm portion 14a of the female fitting portion 14 are inserted into the concave portion 14c of the female fitting portion 14, as shown in FIG. At the same time that the two arm portions 14b return to the original shape, the bifurcated portion on the head 13b side of the male fitting portion 13 also returns to the original shape. Thereby, the vibration when the shape of the female fitting portion 14 returns to the original shape and the vibration when the shape of the male fitting portion 13 returns to the original shape are added together, thereby forming the shape of the female fitting portion 14. As compared with the conventional fitting only with the vibration when returning to the original state, a good wearing feeling can be obtained. Therefore, it is easy to determine whether the male side fitting part 13 and the female side fitting part 14 can be firmly fitted.

In addition, for example, the fitting tool 100 illustrated in FIG. Specifically, the fitting tool 100 includes a male fitting portion 113 and a female side on the opposing surfaces 111a and 112a of the pair of first base material 111 and second base material 112 along the longitudinal direction. A fitting portion 114 is provided. The male side fitting part 113 consists of a pair of arm parts 113a, 113b whose front ends are folded outward, and the female side fitting part 114 is a pair of arm parts 114a, whose front ends are folded back inside. 114b. In the fitting tool 100, the pair of arm parts 113 a and 113 b of the male side fitting part 113 are inserted between the pair of arm parts 114 a and 114 b of the female side fitting part 114, and the arm of the male side fitting part 113 is inserted. The arm portion 114a and the arm portion 114a of the female side fitting portion 114, and the arm portion 113b of the male side fitting portion 113 and the arm portion 114b of the female side fitting portion 114 are respectively hooked so that they can be fitted. ing.
In the fitting tool 100, when fitting, either one of the pair of arm portions 114a and 114b of the female side fitting portion 114 is between the pair of arm portions 113a and 113b of the male side fitting portion 113. Intrusion may cause partial incomplete fitting.
On the other hand, the fitting 10 has a shape in which the middle part of the trunk part 13a to the tip of the head part 13b is divided into two parts, and the first base material 11 side in the trunk part 13a of the male fitting part 13 is divided. Absent. That is, the depth of the recess 13c in the male side fitting portion 13 is not deep enough to allow the first arm portion 14a or the second arm portion 14b of the female side fitting portion 14 to sufficiently enter. It is suppressed that the first arm portion 14a or the second arm portion 14b of the joint portion 14 enters the recess 13c of the male side fitting portion 13 and the fitting is insufficient.
From the above, in the fitting 10, the male-side fitting portion 13 and the female-side fitting portion 14 can be stably fitted, a good wearing feeling can be obtained at the time of fitting, and the fitting can be performed sufficiently. Since it is easy to determine whether or not, the opening of the bag body can be stably closed.

As shown in FIG. 2, the bottom surface 13 d of the recess 13 c is located between the proximal end on the first base material 11 side of the trunk portion 13 a and the distal end on the head 13 b side.
The depth of the recess 13c with respect to the height d _{2 of the} male fitting portion 13 (the length from the tip of the head 13b to the opposing surface 11a of the first base member 11 in the male fitting portion 13; FIG. 2). The ratio d ₁ / d ₂ of the length d ₁ (the length from the end of the concave portion 13c on the front end side of the head portion 13b to the bottom surface 13d. FIG. 2) is preferably 1/10 to 1/1. ~ 1/1 is more preferable.
If the ratio d ₁ / d ₂ is equal to or greater than the lower limit value, a better wearing feeling was obtained when the male side fitting part 13 and the female side fitting part 14 were fitted, and the opening could be closed. It will be easier to judge. If the ratio d ₁ / d ₂ is equal to or less than the upper limit value, the head portion 13b of the male fitting portion 13 can be stably fitted by the concave portion 14c of the female fitting portion 14.

The male side fitting part 13 and the female side fitting part 13 have a cross-sectional shape, except that a concave line 13c is formed and the middle part of the trunk part 13a is divided into two branches from the tip of the head part 13b. What is necessary is just to be able to repeat opening and closing of the opening part of a bag main body by attaching / detaching the side fitting part 14 mutually. Moreover, the cross-sectional shape of the female side fitting part 14 should just have the 1st arm part 14a and the 2nd arm part 14b, and can open and close the opening part of a bag main body repeatedly.
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.
