る。BACKGROUND ART In recent years, various bags have come to be used with the diversification of eating habits and other lifestyles. Among them, a bag (chuck bag) that is openable and closable by providing a band-shaped bite (fitting tool) at the opening of the bag is widely used mainly in the food field. A general occlusion tool includes a male member having a strip-shaped base portion and a female member having a strip-shaped base portion.

（特開昭60-246703 号公報、特開平4-339768号公報参
照）。Conventionally, various structures have been proposed in which the fitting strength of the articulation tool is improved so that the articulation tool does not open even when the internal pressure of the bag increases. For example, there has been proposed a structure in which a thin portion and a thick portion are formed on a strip-shaped base, or a recess which is not adhered to the bag body is formed on the strip-shaped base (JP-A-60-246703 and JP-A-4-339768). (See the official gazette).

は、略対称型となっている。As described above, in the case of the conventional articulation tool, the female member has a shape in which both opposing hook portions (claws) stand up from the strip-shaped base portion in a substantially vertical shape (see, for example, Japanese Patent Laid-Open Publication No. Sho 60-58). -246703), or both hooks (claws) thereof have a shape that rises up from the belt-like base in a substantially arc shape (for example, the articulation of JP-A-4-339768). ). Both hooks of the conventional female member are substantially symmetrical.

There is a drawback that the fitting strength against the pressure to open inside the bag is also small. On the other hand, according to the articulation tool provided with the female member having the hook portion that rises up in a substantially arc shape, contrary to the case of the above-mentioned articulation tool, the fitting strength against the internal pressure of the bag is large, but the opening side of the bag is There is a drawback that the bag is difficult to open because the fitting strength against the force from is large.

とする。The first invention of the present invention comprises a male member and a female member that engages with the male member, wherein the male member is a belt-shaped base and a head connected to the belt-shaped base. The female member has a strip-shaped base, a first hook formed on the strip-shaped base, and a second hook formed on the strip-shaped base so as to face the first hook. And a first portion and a second hook portion, a concave portion into which the head of the male member is fitted is formed, and the first hook portion rises from the strip-shaped base portion in a substantially arc shape. An engaging device having a shape, wherein the strip-shaped base portion passes through an intermediate portion between an end edge of the first hook portion and an end edge of a second hook portion in a cross section in a direction orthogonal to a longitudinal direction of the strip-shaped base portion. The line vertically lowered with respect to the L1 line, the outer peripheral surface of the first hook portion from the L1 line Farthest point of the X1, the point rising from strip-like base portion of the first hook portion X2, wherein X in
Of the outer peripheral curve S1 from 1 to X2, the closest point to the L1 line is defined as X3, and the point where a line perpendicularly intersecting with the L1 line through the X1 intersects with the outer peripheral surface of the second hook portion is Y1, the point rising from the strip base of the second hook portion is Y2, and the outer peripheral curve from Y1 to Y2 is S
2. If the line vertically passing through the Y1 and perpendicular to the strip base is the L2 line, and if the S2 is located in a direction away from the L1 line with respect to the L2 line, then from the L1 line Let a be the length up to X3, and Y3 be the point where the line that intersects the L1 line through the X3 perpendicularly intersects the outer peripheral surface of the second hook portion, and the length from the L1 line to this Y3. If b1 is set, b1 is larger than a.

に対する嵌合強度は余り強くなっていない。The case where S2 is located in the direction away from the L1 line with respect to the L2 line means that the outer peripheral curve S2
Refers to a case where the taper is flared toward the side of the strip-shaped base. In this case, a part of the outer peripheral curve S2 on the Y1 side is L
It may overlap with two lines, or Y1 of the outer peripheral curve S2
It is also possible that a part of the side does not overlap the L2 line and immediately becomes apart from the L2 line and becomes divergent. According to the present articulation tool, the fitting strength with respect to the opening force on the first hook portion side can be increased, while the fitting strength with respect to the opening force on the second hook portion side is not so strong.

When b1 / a <1.5, the fitting strength on the first hook portion side and the fitting strength on the second hook portion side cannot be balanced at the same time. There is no particular upper limit for b1 / a, but if b1 / a is too large, the material will be wasted. Therefore, depending on the material, even if b1 / a is made larger than 5, the effect of the present articulation tool does not change much.
