[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sealing slide fastener which is made of a soft plastic and has two confronting tapes which are integrally formed with each other and which are engaged and disengaged by a slider.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, two tapes (1) and (2) made of soft plastic and facing each other have a groove groove articulator and a convex groove articulator linearly integrated over the entire length. In a slide fastener which is molded and engages and disengages both articulators with a slider (3), the tapes (1) and (2) are usually sealed at both ends, and the slider ( 3) is always provided with a separating piece (31) which is inserted between the groove groove obturator of the tapes (1) and (2) and the convex groove obturator and releases the engaged obturator. Therefore, when the slider (3) is moved from one end to the other end of the tapes (1) and (2) to engage both articulators, the slider (3) is separated into the separating pieces (31). However, in this state, the separating piece (31) of the slider (3) remains in the space between the two articulators, that is, the two occlusal areas from the other end to the separating piece (31). The child is not engaged and part (a) remains open. This is because the slide fastener of the conventional structure has the slider (3), so that the articulator cannot be completely engaged over the entire length and cannot be hermetically sealed, so that it cannot be sealed in rainy weather or especially underwater. However, there is a problem in that the use of water does not have a waterproof effect and a moisture-proof effect due to the ingress of water.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and even with a fastener having a slider, the articulator can be completely sealed over the entire length and can be waterproof and moisture-proof. It is an object of the present invention to provide a slide fastener that is easy to open or open a combined articulator.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] The structure of the present invention for solving the above problems will be described with reference to FIGS. 1 to 4 corresponding to the embodiments. The present invention is based on two soft plastic tapes. The main bodies (1) and (2) are arranged in parallel, and on opposite sides of the two tape main bodies (1) and (2), there are concave groove articulators (12) facing each other along the longitudinal direction thereof. A slide fastener having a slider- (3) for separately molding the ridge-shaped articulator (21) and integrally engaging or releasing the groove-shaped occlusal element (12) and the ridge-shaped articulator (21), The groove groove articulator (12) and the convex stripe articulator (21) are provided along at least one longitudinal end of the both tape main bodies (1) and (2) along the upper edge side, and the other end. Incline from the vicinity toward the lower end of the other end. Further, the slider (3) is attached in such a direction that the two articulators (12), (21) are engaged by moving from one end side to the other end. At the position where the slider (3) reaches the other end, the separating piece (31) of the slider (3) is shaped so as to be disengaged from both the articulators (12), (21).

[0005]

[Action]

 When the slider (3) located at one end side of both open articulators (12), (21) is moved to the other end side, both articulators (12), (21) are engaged and eventually When the slider (3) reaches the vicinity of the other end, a part having a gripping width (T) below the slider (3) is hooked on both of the inclined articulators (12) and (21), and this oblique direction The two articulators (12) and (21) are engaged. Then, immediately before the slider (3) reaches the other end, the separating piece (31) of the slider (3) is disengaged from both the articulators (12), (21), so that the slider (3) ends, that is, When reaching the other end, both articulators (12), (21) are completely engaged. Therefore, the tape bodies (1) and (2) are sealed by the two articulators (12) and (21) over the entire length. Also, in the case where both articulators (12) and (21) are branched near the other end, the separating piece (31) is inserted between the branched upper two articulators (12) and (21). It is easy to open the engagement with the slider (3) because the upper part is engaged while leaving a part, and the upper triangular shape of the obliquely attached articulators (12) and (21) It becomes difficult for water to collect in the space.

[0006]

Embodiment An embodiment of the present invention will be described below with reference to the drawings. (1) and (2) are long soft plastic tape bodies arranged in parallel, and both ends in the longitudinal direction are adhered to each other by heat seal. Further, on the opposite sides of the tape bodies (1) and (2), a grooved groove obturator (12) and a convex grooved obturator (21) are integrally formed over the entire length in the longitudinal direction. More specifically, the tape main body (1) is formed with a concave groove articulator (12), and the tape main body (2) is formed with a ridge articulator (21). The groove groove articulator (12) and the convex stripe articulator (21) are upward from the one end on the engagement start side to the vicinity of the other end on the engagement end side in the longitudinal direction of the tape bodies (1) and (2). It is provided along the edge as in the conventional case, and is inclined downward from the vicinity of the other end to the other end.

FIG. 3 shows another embodiment. In this case, the concave groove articulator (12) and the convex streak articulator (21) are the same as those of the tape main bodies (1) and (2). The upper edge side is formed straight over the entire length in the same manner as in the past, and the concave groove articulator (12) and the convex ridge articulator (21) branching from the vicinity of the other end are formed obliquely downward to the other end. There is. In addition, the stepped portion (13) is formed by thickening the outer side of the portion forming the groove groove articulator (12).

(3) is a slider in which both upper ends of the tape bodies (1) and (2) are straddled and sandwiched, and one of the lower portions is engaged with the stepped portion (13) of the tape body (1). The separation piece (31) hanging in the front middle is integrally formed, and the lower part of the slider (3) is inclined near the other ends of the tape bodies (1) and (2). Both the articulators (12), (21) can be engaged inward from the rear to the lower part of the front end on the side of the separating piece (31) so that the entire articulators (12), (21) are completely engaged. The holding width (T) is set. That is, at the position where the slider (3) is stopped at the other end of the tape bodies (1) and (2) during the engagement, at least the lower part of the slider (3) should be at the lower position. The holding width of the shape that is extended from the separating piece (31) so as to reach the other end of the main body (1), (2), and that is aligned with the diagonal direction of both articulators (12), (21) ( T) is secured and is narrower than the open upper part with the separating piece (31) and is the same as the rear gripping width (T). Further, the separating piece (31) is formed in an arched shape so that the rear part is aligned with the oblique direction of the articulators (12), (21) with a size that deviates from the obliquely tilted articulators (12), (21). There is. (4) is a plastic bag that holds things. The articulators (12) and (21) are one station, but may be two stations or more to improve the sealing performance.

[0009]

[Effect of device]

 As described above, the present invention makes the slider (3) by tilting the concave groove obturator (12) and the convex striking obturator (21) at the other end side of the tape bodies (1) and (2). ), When the slider (3) reaches the other end, the separating piece (31) should be positioned in both the articulators (12), (21) in the inclined part. Since they disengage from each other, the tape bodies (1) and (2) are completely engaged over the entire length, and exert a waterproof effect and a moisture proof effect. Further, the disengaged state can be easily performed by the slider (3). Further, even for sealing, the structure is extremely simple, there is no fear of failure, and the manufacturing cost is low.
