Embodiment 1

[0077] figure 1 It is a plan view which shows the slide fastener with a separable insert of this Example 1. figure 2 It is a plan view enlargedly showing the meshing state of fastener elements, image 3 is along figure 2 Sectional view along line III–III shown. in addition, Figure 4 It is a three-dimensional view of the stick, Figure 5 It is a three-dimensional view of the seat post and the seat body.

[0078] In addition, in the following description, the length direction of the fastener tape is defined as the front-rear direction, especially in the present embodiment 1, the direction in which the slider is slid so as to separate from the insert is defined as the front, and the direction in which the slider is slid so as to approach The direction to separate the inserts as the rear. In addition, the width direction of the chain tape of the chain tape is defined as the left-right direction, and in particular, the figure 1 The left side in the top view of such a sl...

Embodiment 2

[0149] Figure 19 It is the plan view which shows the slide fastener with the separation insert of this Example 2, Figure 20 It is a top view which shows the state which opened the left and right fastener stringers of this slide fastener. In addition, in this Example 2, about the member which has the same structure as the slide fastener of said Example 1, the code|symbol same as that of said Example 1 is used, and description is abbreviate|omitted.

[0150] In the case of the slide fastener 2 of the second embodiment, the left and right first fastener chain 10a and the second fastener chain 10b are configured in the same manner as in the first The front end of the fastener chain 10b is provided with a separate insert 50, and the rear end of the first fastener chain 10a and the second fastener chain 10b is provided with a separate insert 60, and the front and rear paired first slider 20a and The 2nd slider 20b is arrange|positioned so that it can slide along the element row ...

Abstract

In this slide fastener with an separable stop (1), a box body (33) comprises a hollowed out recess (33d) which is drilled from an end face of a protruding side of the box body (33) deeper than a tape edge (11d) of a fastener tape (11), and a tape enclosure (33e) which encloses an edge part (11e) of the fastener tape (11) inside the hollowed out recess (33d). According to the present invention, even when the box body (33) is increased in size, since the actual thickness of the box body (33) is reduced by the hollowed out recess (33d), shrinkage cavities or flow lines can be prevented in the injection molding of the box body (33). In addition, the position of the fastener tape (11) is stabilized in the cavity space during injection molding, preventing the fastener tape (11) from being exposed on the surface of the box body (33). Furthermore, the tape enclosure (33e) secures a bond area of the box body (33) to the fastener tape (11), thereby increasing bond strength of the box body (33).

Description

technical field [0001] The present invention relates to a zipper with separate inserts, in particular to a belt separation that does not cause sink marks and other poor forming phenomena on the seat body that is injection molded on the chain belt, and that has a high fixing strength for the seat body relative to the chain belt. A zipper for an insert, wherein the separate insert has a plunger, a seat rod and a seat body. In addition, the present invention also relates to a mold for injection molding capable of molding the seat bar and the seat body to the chain belt. Background technique [0002] For example, in the conventional slide fastener used for the front body of clothing, the separation insert is arrange|positioned at the one end part of the fastener chain on either side in many cases. Usually, the separation insert includes: a plunger, which is fixed to the side edge of the chain belt adjacent to the chain element row of one zipper fastener chain; The side edge of...
