〈産業上の利用分野〉
本発明は、開口部に再開閉可能な咬合具を備えた合成樹
脂製の袋体に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a synthetic resin bag provided with a re-closable closure at its opening.

した雌爪９とから構成されている。<Prior Art> As shown in FIG. 5, it is known that a bag 1 made of synthetic resin is provided with a re-closable articulating device 3 in an opening 2 thereof. As shown in FIG. 6, the conventional structure of the articulating tool 3 includes a male claw 6 in which an arrowhead-shaped claw 5 is formed at the tip of the shaft portion 4;
It consists of a female claw 9 having a claw 8 formed at both ends of the opening of the groove 7 with which the male claw 6 engages.

については満足されていない。<Problems to be Solved by the Invention> In the articulating tool provided in the conventional bag described above, consideration is given only to storing and holding articles and smoothly opening and closing the opening of the bag when taking them in and out. However, the seven airtight functions required to maintain quality when the stored items are foods are not satisfied.
第６図で示す雄爪６、雌爪９からなる咬合具３を備えた

先などにより開脱状態にある咬合具３を加圧摺動するこ
とにより行われる。In a bag body 1 equipped with an articulating tool 3 consisting of a male claw 6 and a female claw 9 as shown in FIG. 6, when closing the opening 2, the articulating tool 3 in an open and retracted state is generally pressurized with a fingertip or the like. This is done by sliding.
そして、雄爪６の矢先形の爪５の鉤先端αが雌爪９の鉤
爪８の鉤先端すを通過した時点で両爪６％９の咬合が完
了する関係にある。従って。There is a relationship in which the occlusion of both claws 6%9 is completed when the hook tip α of the arrowhead-shaped claw 5 of the male claw 6 passes the hook tip of the claw 8 of the female claw 9. Therefore.
雌爪９の凹溝７の空間断面積は雄爪６の矢先形の爪５の
断面積よりも当然大きくなっている。The spatial cross-sectional area of the groove 7 of the female claw 9 is naturally larger than the cross-sectional area of the arrowhead-shaped claw 5 of the male claw 6.
このような関係であるため、咬合が完了した後において
も、雄爪６の矢先形の爪５と雌爪９の凹溝７との間には
第６図で示すように間隙が生じ、両爪６．９が密着し合
うことがなく前記間隙を通して袋体内外は通気が自由に
行われる。Because of this relationship, even after occlusion is completed, a gap is created between the arrowhead-shaped claw 5 of the male claw 6 and the concave groove 7 of the female claw 9, as shown in FIG. The claws 6.9 do not come into close contact with each other, and ventilation can freely occur inside and outside the bag body through the gap.

としては短期の保存はとも力１くとして長期保存には適
当ではない。Therefore, even if the bag is made of a multi-layer film material made by laminating aluminum foil and polyethylene film, which have excellent air and moisture proof properties, the air and moisture proof function may be compromised due to the non-airtightness of the part of the articulating tool 3. Its value had been halved. For this reason,
As bags for packaging coffee, tea, seaweed, etc., which are sensitive to fragrance and humidity, they are not suitable for short-term storage, and are not suitable for long-term storage.

It provides a bag with a built-in bag, and its characteristic configuration is as follows:
A bag made of synthetic resin in which an opening is provided with an articulating tool consisting of a male claw with an arrowhead-shaped claw formed at the tip of the detail, and a female claw with claws that the male claw engages with at both ends of the opening of a groove. In the body,
The shaft portion of the male claw has a wedge shape in which the cross-sectional width of the base portion is wider than the cross-sectional width of the distal neck portion.

The male claw is elastically deformed so as to accumulate a repulsive force that urges the male claw in the backward direction. When the pressure on the fingertip is released after occlusion is completed, the male claw is moved backward by the restoring repulsive force of the claw of the female claw, and the arrow-shaped claw of the male claw tightly engages with the claw of the female claw, causing the occlusal tool to move. Keep airtight.

In FIG. 1, 3 is an articulating tool consisting of a male claw 6 and a female claw 9. The male claw 6 has an arrowhead-shaped claw 5 formed at the tip of the shaft portion 4 . The shaft portion 4 has a wedge shape in which the cross-sectional width D1 of the base portion 10 is wider than the cross-sectional width D2 of the distal neck portion 11. The female claw 9 has claws 8 formed at both ends of the opening of the groove 7. The tips of both claws 8 are spaced apart by a predetermined width D3.

部の前進方向に彎曲変形される。Next, the operation of the present invention will be explained. When closing the articulating tool 3 from the opened/retracted state of the male claw 6 and female claw 9 shown in figure fa1, the fingertips are pressed and slid as usual. As a result, the arrowhead-shaped claw 5 of the male claw 6 expands the distance D3 between the two claws 8 of the female claw 9 and enters into the groove 7. At this time, the tips of the claws 8 of the female claws 9 as shown in FIG. Curved deformation occurs.

内容品の揺動圧によって咬合位置のずれが防止される。As a result, the claw 8 becomes in a state nlζ in which a repulsive force that urges the male claw 6 in the backward direction is accumulated. Therefore, when the pressure applied by the fingertips is released after the male claw 6 and the female claw 9 have completed occlusion, the repulsive force of the claw 8 acts on the shaft portion 4, causing the male claw 6 to move backward. By this backward movement of the male claw 6, as shown in FIG. 4, the arrowhead-shaped claw 5 of the male claw 6 and the claw 8 of the female claw 9 come into close surface contact with each other, creating an airtight state. In this state, in the case of another modified example shown in FIG. The rocking pressure of the body contents prevents the occlusal position from shifting.

During occlusion due to pressurized sliding of the female claws, a repulsive force that urges the male claws in the backward direction is accumulated in the claws of the female claws that come into contact with the inclined surfaces of the details of the model. The male claw is moved backward and the male and female claws come into close contact, ensuring airtightness when the articulator is opened.
