Description

Zipper slider

The present invention relates to a slider for a slide fastener.

A technique for attaching a tab to a slider body having a cantilever-shaped tab mounting post is known. Since the tab is allowed to be mounted, there is a gap between the free end of the tab mounting post and the flap above the slider body. This clearance is required for the rear mounting of the tab, but is no longer required after the tab is installed. Therefore, in some methods, after the tab is mounted, an operation of plastically deforming the tab mounting post to reduce the gap is performed. However, in this case, it may be desirable to suppress undesired deformation of the slider body due to the force imparted to the tab mounting post, such as variations in the spacing between the upper and lower flaps.

Even if the tab mounting post is plastically deformed as in the above-described example, there is a slight gap remaining and foreign matter such as a bag or the like is interposed in the gap so that the ease of use of the zipper is lowered.

On the other hand, among other methods, it is known that the gap between the free end of the tab mounting post and the upper flap is closed by the closing member according to the above-exemplified viewpoint or the above-mentioned viewpoint, thereby filling the gap. . For example, in Patent Document 1, it is disclosed that, as disclosed in FIG. 1, FIG. 4, and FIG. 7 of the document, the flap is inserted between the upper end of the slider main body and the free end of the tab mounting rod. The technology of components. The same sealing member is also disclosed in Patent Document 2. As can be understood from Fig. 10 of Patent Document 2, the guiding portion 67 of the closing member 60 is fitted into the guiding groove 41d of the upper blade 41, thereby easily securing the positioning of the closing member 60 with respect to the slider body 40 (refer to the Paragraph 0098 of the literature.

Figure 10 is a schematic partial schematic view of the slider of the pull tab, showing the state in which the closing member is mounted between the upper end of the slider body and the free end of the tab mounting post, and the closing member is partially broken away. The main body portion is placed on the mounting portion of the upper blade, and the fitting projection of the closing member is fitted into the fitted hole of the mounting portion.

As shown in FIGS. 1 to 10, the slider 400 with a pull tab includes a slider body 100, a closing member 200, and a pull tab 300. The slider 300 is attached to the slider body 100, and thereafter, the shutter member 100 is attached to the slider body 100, whereby the shutter member 300 is prevented from being detached from the slider body 100 by the closing member 200, and the slider body 100 is detachable. In addition to the mounting tab 300. In terms of such an assembly sequence, the pull tab 300 can be allowed to be mounted later. In other words, the degree of freedom in attaching the tab 300 to the slider body 100 is improved. There is also the advantage that the slider body 100 can be cut into the slider 300 to manufacture the slider 400. Further, a part in which the closing member 200 and the slider body 100 are separated is understood as a part unit. The three parts including the pull tab 300 can also be understood as a part unit.

The slider 400 is a slider for zipper, and the slider is opened and closed by the movement of the slider 400 before and after. In detail, by the forward movement of the slider 400, the left and right fastener elements are engaged, so that the left and right fastener stringers are closed. By the rearward movement of the slider 400, the engagement of the left and right fastener elements is released, so that the left and right fastener links are opened. Furthermore, the type or composition of the zipper is arbitrary. The type or configuration of the zipper element is also arbitrary, and is assumed to be a ring fastener element, a resin element, or a metal element.

The use of a zipper assembled with a slider 400 involves a number of aspects. For example, as a pull The use of the chain can be exemplified by clothes, bags, and bags. As described above, the slider 400 of the present embodiment allows the mounting after the tab. Therefore, even if the pull tab for the above-mentioned wide-purpose zipper is damaged after the fact, it can be handled by replacing the pull tab.

For example, it is assumed that the slider 400 is assembled to the zipper sewn on the bag, and the tab 300 of the slider 400 is partially broken, but the concept is not limited. That is, in this case, the gap 80 of the slider body 100 can be restored by breaking or unloading the closing member 200 of the slider 400, and the damaged tab can be replaced with a new tab of the same or different type. Avoid replacing the entire package to meet the needs of the user.

When replacing the pull tab, it is desirable to prepare a new closure member 200. Unloading the closure member 200 from the slider body 100 without deformation or damage is not straightforward. It is relatively simple to destroy the closure member 200 for replacing the tab. Furthermore, even if the closure member 200 is broken for some reason, it can be replaced with a new closure member. The closure member 200 can also be heated to cause it to deform.

The slider body 100 is made of metal, resin or any other material. The closure member 200 is constructed of metal, resin, or any other material. The pull tab 300 is composed of metal, resin or any other material.

In one non-limiting example, the slider body 100 is made of metal, the closure member 200 is resinous, and the pull tab 300 is made of metal. In this example, the attachment of the closure member 200 to the slider body 100 is facilitated. In the present example, the closure member 200 is constructed of a resin that is both rigid and slightly soft. That is, the closure member 200 is constructed of a material that is softer than the slider body 100. The sealing member 200 is formed of a molded article integrally formed by injection molding using a thermoplastic resin material such as polyacetal, polyamide, polypropylene, or polybutylene terephthalate, but has no intended purpose. .

The method of manufacturing the slider body 100, the closing member 200, and the tab 300 is arbitrary. For example, the slider body 100 is manufactured by die-casting of a metal material, and the sealing member 200 is manufactured by molding a resin mold, and the tab 300 is formed by die-casting of a metal material. Manufactured, but the above is not intended to be limited. The metal pull tab 300 may cause a relatively strong impact on the closure member 200. This point is more pronounced when compared to, for example, a pull tab.

The pull tab 300 has a base end 302 and a grip end 304, and a metal flat plate with holes 320, 340 is formed at each end portion. The pull tab 300 is attached to the pull tab mounting post 50 by the tab mounting post 50 passing through the aperture 320 of the tab 300. By closing the gap 80 by the closure member 200, the tab 300 is attached to the tab mounting post 50 in an inseparable manner. Again, the aperture 320 does not have to be completely closed.

The slider body 100 includes an upper blade 10, a lower blade 20, a connecting post 30 that connects the upper blade 10 and the lower blade 20, and a cantilever-shaped tab mounting post 50 that is provided on the upper blade 10. The slider body 100 has a front end portion 101 that is located on the side where the upper blade 10 and the lower blade 20 are coupled by the connecting post 30, and a rear end portion 102 that is opposite to the front end portion 101.

At the front end portion 101 of the slider body 100, a pair of right and left biting inlets (also referred to as inlet ports) are provided through the connecting post 30. An end port 102 is provided at the rear end portion 102 of the slider body 100. The zipper element moves in a Y-shaped sprocket path defined by the upper blade 10, the lower blade 20, and the connecting post 30. The left and right zipper elements of the meshing state are inserted into the engaging opening, and the left and right zipper elements of the non-engaged state are inserted into the left and right pair of engaging openings. A pair of right and left flange portions 15 are provided on the upper blade 10 to restrict left and right displacement of the fastener elements.

The shape and/or arrangement of the flange portion 15 can be changed according to various conditions, for example, a form or a use form of a fastener stringer (also referred to as a fastener chain) in which a fastener element is fixed to a fastener stringer. For example, when the ring fastener element is attached to one side of the fastener chain cloth so that the fastener element can not be seen from the front side, the flange portion 15 is disposed on the lower wing panel 20 instead of the upper wing panel. 10. When the zipper chain of the formed resin sprocket is integrally molded to the zipper chain cloth, or the zipper chain of the metal sprocket is fixed to the zipper chain cloth, the upper flap 10 and the lower flap 20 are disposed. Flange portion 15.

The upper wing plate 10 and the lower wing plate 20 are oppositely disposed on the flat plate portion, and each has an outer surface and The inner surface. Furthermore, the inner surface of the upper wing 10 is opposed to the inner surface of the lower wing 20, and this may also be referred to as a facing inner surface. The outer surface of the upper blade 10 is attached to the opposite side of the inner surface of the blade 10. The outer surface of the lower wing 20 is the opposite side of the inner surface of the lower wing 20. Furthermore, if the upper faces of the upper blade 10 and the lower blade 20 are understood in accordance with the up and down direction, the outer surface of the upper blade 10 is the upper surface of the upper blade, and the inner surface of the upper blade 10 is the upper blade. Under the surface. Similarly, the outer surface of the lower wing 20 is the lower surface of the lower wing, and the inner surface of the lower wing 20 is the upper surface of the lower wing.

The upper wing 10 and the lower wing 20 have the same or substantially the same top view shape or bottom view shape. The connecting post 30 connects the front end portion 11 of the upper flap 10 and the front end portion 21 of the lower flap 20 to the left and right centers, thereby making the inner end surface of the upper flap 10 offset from the front end portion 11 and the lower flap 20 Portions of the front end portion 21 of the surface are connected via the connecting post 30. The connecting post 30 has an upper end portion that is coupled to the front end portion 11 of the inner surface of the upper blade 10 and an upper end portion that is coupled to the front end portion 21 of the inner surface of the lower flap 20, and is vertically up and down between the upper end portion and the lower end portion. extend.

The pull tab mounting post 50 has a base end portion 51 that is coupled to the distal end portion 11 of the outer surface of the upper blade 10, and a free end portion 52 that is remote from the upper blade 10 and that is not coupled to the upper blade 10. The base end portion 51 of the tab mounting post 50 extends upward from the outer surface of the upper flap 10. Between the base end portion 51 and the free end portion 52 of the tab mounting post 50, an intermediate rod portion 53 extending straight from the upper end of the base end portion 51 to the rear end of the free end portion 52 is provided. The intermediate rod portion 53 is located between the base end portion 51 and the free end portion 52 and extends substantially parallel to the upper blade 10 in the front-rear direction. The intermediate rod portion 53 has a flat lower surface 53j opposed to the upper surface 10j of the upper blade 10.

The pull tab mounting post 50 is provided with a through hole 55 that penetrates the base end portion 51 forward and backward, and is provided with a groove portion 56 in which the lower surface 53j of the intermediate lever portion 53 is concave. The through holes 55 and the groove portions 56 are provided from the core of the die casting apparatus. The groove portion 56 is provided in a concave shape upward in the center from the left and right of the lower surface 50b of the handle mounting post 50. The depth of the groove portion 56 gradually decreases toward the rear toward the free end portion 52 of the tab mounting post 50. The groove portion 56 is in spatial communication with the through hole 55.

The lower surface 52j of the free end portion 52 of the pull tab mounting post 50 is provided with a snap projection 60 extending downward toward the upper flap 10. The width of the snap projection 60 is narrower than the left and right width of the tab mounting post 50. Furthermore, the lower surface of the tab mounting post 50 opposite the upper flap 10 can be understood to include the concept of the lower surface 53j of the intermediate stem portion 53 and the lower surface 52j of the free end portion 52.

The engaging projection 60 includes a wide portion 61 having a wide left and right width and a narrow portion 62 having a narrow left and right width. The narrow portion 62 is disposed at the center of the left and right of the wide portion 61, and is formed in a plane perpendicular to the vertical direction. T-shaped. The wide portion 61 is a portion in which one of the following closing members 200 is enlarged between the claw portions 215. The narrow portion 62 is a portion that is sandwiched by the pair of claw portions 215 after the pair of claw portions 215 pass through the wide portion 61. The left and right edges of the wide portion 61 are chamfered in an arc shape. On the other hand, the left and right inner edges of the front side of the claw portion 215 are chamfered in an arc shape, thereby smoothly expanding the left and right intervals of the claw portion 215. The wide portion 61 is disposed on the side of the free end portion 52 of the tab mounting post 50 on the narrower portion 62. The narrow width portion 62 is provided on the side of the base end portion 51 of the pull tab mounting post 50 on the wider width portion 61.

The wide portion 61 has a rear surface 61c and a front surface 61d on the side opposite to the rear surface 61c. The rear surface 61c of the wide portion 61 is flush with the rear surface of the free end portion 52. Further, the front surface 61d of the wide portion 61 is opposed to the side of the base end portion 51. The narrow portion 62 is provided at the left and right centers of the front surface 61d of the wide portion 61, and protrudes toward the base end portion 51. The wide portion 61 is disposed further rearward than the base end portion 51 of the tab mounting post 50 than the narrow web portion 62. Since the narrow portion 62 is provided at the center of the left and right sides of the front surface 61d of the wide portion 61, the front surface 61d of the wide portion 61 is divided or divided into a pair of left and right sides sandwiching the narrow portion 62. The front surface 61d of the wide portion 61 divided or divided by the narrow width portion 62 in this manner is used to lock the locking surface 61d of the claw portion 215 of the closing member 200. The wide portion 61 defines the front and rear thickness of the wide portion 61 by the locking surface 61d and its opposite side rear surface 61c. The locking surface 61d of the wide portion 61 is disposed perpendicularly with respect to the lower surface 52j of the free end portion 52, but may be disposed obliquely.

As shown in FIG. 8, the maximum left and right width W61 of the wide portion 61 is narrower than the minimum left and right width W55 of the through hole 55, but even in this case, the closing member 200 and the engaging protrusion can be ensured. From the full complement of 60.

As shown in FIG. 3 and the like, there is a gap 80 between the free end portion 52 of the pull tab mounting post 50 and the flap 10 above the slider body 100. In more detail, there is a gap 80 between the snap projection 60 of the free end 52 of the tab mounting post 50 and the flap 10 above the slider body 100. This gap 80 is closed by the closure member 200. Further, the lower surface 60b of the engaging projection 60 is gradually away from the inclined surface of the upper surface 10j of the upper blade 10 from the rear direction.

A partition structure for separating the moving space regions of the fastener elements is provided on each of the pair of inward surfaces of the upper blade 10 and the lower blade 20. As shown in Fig. 10, a partition structure 16 for separating the moving space regions of the left and right fastener elements is provided on the inwardly facing surface of the upper blade 10. The partition structure 16 extends from the rear end portion 102 of the slider body 100 toward the front end portion 101. The partition structure 16 is a Y-shaped recessed portion which is branched into two by the connecting post 30, and includes a branch portion 16m branched into a V shape and a linear rod portion 16n.

In the present embodiment, the partition structure 16 is partially removed by the fitting hole 75 of the mounting portion 70 of the upper blade 10 described below. However, since the length of the fitted hole 75 before and after is shorter than the length of the mounting portion 70 before and after, the removal range of the partition structure 16 is limited. Furthermore, the partition structure 16 is also disposed in the same inward facing surface of the lower wing panel 20. The partition structure 16 has a structure in which a loop of a monofilament is spirally wound.

A concave mounting portion 70 extending in the front-rear direction is provided at the left and right centers of the upper blade 10. The placing portion 70 extends from the rear end portion 12 of the upper blade 10 to the base end portion 51 of the tab mounting post 50 that is coupled to the front end portion 11 of the upper blade 10. The extending direction of the mounting portion 70 coincides with the direction in which the tab mounting post 50 extends, and the dimension in the left and right width direction of the mounting portion 70 is larger than the left and right width dimensions of the tab mounting post 50. The mounting portion 70 has an arc-shaped mounting surface 74 that is gently inclined from the left and right sides toward the left and right centers. The mounting surface 74 is a concave shape based on the upper surface 10j of the upper and lower blades 10 as a reference. In the left-right direction, the upper side of the arc-shaped mounting surface 74 is not closed and is liberated. By arranging the placing portion 70 in this manner, it is easy to mount the closing member 200 on the mounting surface 74, and it is also easy to secure the left and right of the closing member 200. Bit. The depth of the mounting portion 70 on which the upper surface 10j of the upper blade 10 is the reference is gradually shallower from the rear toward the front. The arc-shaped mounting surface can also be simply referred to as an arc surface.

The mounting portion 70 is provided with a fitting hole 75 in a state in which the rear end portion of one of the end portions of the upper blade 10 is cut. The fitting hole 75 is a hole that penetrates the end portion of the upper blade 10 up and down, and is attached to the rear edge of the upper blade 10 to form a hole having a concave shape that is concave toward the front. Further, it is also understood that the fitting hole 75 is a hole in which the rear end portion of the placing portion 70 is cut.

The fitting hole 75 has a width dimension that is smaller than the left and right width dimensions of the mounting portion 70 and is provided at the center of the left and right of the mounting portion 70, but is not necessarily limited thereto. The fitting hole 75 extends in the front-rear direction similarly to the handle mounting post 50 and the mounting portion 70. However, the dimension of the fitted hole 75 in the front-rear direction is shorter than the dimension of the mounting portion 70 in the front-rear direction. Further, the number of the fitting holes 75 and the following fitting projections 220 corresponding thereto are arbitrary. In other aspects, a plurality of fitted holes 75 and a plurality of fitting projections 220 are provided.

As shown in FIG. 4, the length L75 of the fitting hole 75 in the front-rear direction is sufficiently shorter than the length L70 of the mounting portion 70 in the front-rear direction. For example, the length L75 of the fitting hole 75 is shorter than the front and rear direction of the engaging projection 60 of the handle mounting post 50, and is 1/2 or less, or 1/3 or less of the length L70 of the mounting portion 70, or 1 /4 or less, or 1/5 or less, or 1/6 or less. The displacement of the closing member 200 can be sufficiently restricted by the fitting hole 75 occupying a shorter distance while ensuring stable movement of the closing member 200 by the placing portion 70 occupying a longer distance in the front-rear direction. In the embodiment in which the above-described compartment structure 16 is provided, the removal range may be minimized.

At the end position of the fitting hole 75, a terminating surface 75b which is also a side surface defining the fitting hole 75 is provided. The end face 75b is a face that defines the end position of the insertion of the fitting protrusion 220 of the closing member 200 described below. As shown in FIG. 5, the end surface 75b and the locking surface 61d are provided in the same plane PL6175. That is, the end surface 75b is substantially or completely flush with the locking surface 61d. The claw portion 215 of the following sealing member 200 is prevented from being displaced rearward of the fitting protrusion 220 in a substantially or completely the same plane, thereby reducing the sway of the closing member 200.

The closure member 200 has a body portion 250 and a fitting protrusion 220 protruding from a lower surface 255 of the body portion 250. The lower surface 255 of the main body portion 250 of the closing member 200 is a surface to be placed placed on the mounting surface 74 of the mounting portion 70. The lower surface 255 of the body portion 250 has a surface shape complementary to the mounting surface 74, ensuring stable surface contact with the mounting surface 74.

The body portion 250 of the closing member 200 has a pair of right and left wall portions 210 and a base portion 230 disposed between the pair of right and left wall portions 210. The pair of left and right wall portions 210 are provided to grip the snap projections 60 of the free end portion 52 of the tab mounting post 50. At the front end of each wall portion 210, a claw portion 215 that protrudes inward in the left-right direction so as to narrow the interval between the wall portions 210 is provided. The claw portion 215 is disposed offset from the rear surface 210c of the wall portion 210. This offset amount corresponds to the thickness of the wide portion 61 of the engaging projection 60 before and after.

When the pair of wall portions 210 pass the wide portion 61 of the engaging projection 60, the wall portions 210 are elastically tilted outward in the left-right direction, and the claw portions 215 are elastically displaced outward in the left-right direction. When the engaging projection 60 passes through the wide portion 61, the wall portions 210 are elastically restored to the original shape, the interval between the claw portions 215 is restored to the original interval, and the narrow portion 62 of the engaging projection 60 is sandwiched by the left and right claw portions 215. hold. Thereby, the pair of wall portions 210 are used to sandwich the engaging projections 60 from the left and right, and the left and right displacement and rearward displacement of the closing member 200 with respect to the engaging projections 60 are restricted. The engaged surface 215c of the rear surface of the claw portion 215 is a flat surface, and is ensured to be in contact with the surface of the locking surface 61d of the wide portion 61 of the engaging projection 60.

A front inclined portion 218 that descends in the insertion direction is provided at an end portion of the body portion 250 of the closing member 200. The body portion 250 of the closure member 200 includes an upper end portion that is thicker in the insertion direction of the closure member 200, that is, from the rear toward the front. Due to such a configuration, the insertion of the closing member 200 into the gap 80 between the engaging projection 60 and the placing portion 70 is more easily ensured.

As described above, the body portion 250 of the closing member 200 has a base portion 230 that is disposed opposite the engaging projection 60 at the center of the left and right of the wall portion 210. Grooves extending in the front-rear direction are provided at the left and right centers of the base portion 230. As shown in FIG. 10, the left and right centers of the snap protrusions 60 are provided. The lower end portion 66 is narrowed downward, and the lower end portion 66 of the engaging projection 60 is disposed in the recess of the base portion 230. By providing the base portion 230, the strength of the closing member 200 becomes high, and the support point of the engaging projection 60 can be increased. Further, as shown in FIG. 10, since the groove is formed between the base portion 230 and each of the wall portions 210, the pivoting of the respective wall portions 210 can be ensured.

The body portion 250 of the closing member 200 has a lower surface 255 which is a mounting surface placed on the mounting surface 74 of the mounting portion 70. The lower surface 255 is an arcuate surface that is convex downward in the left-right direction. A fitting protrusion 220 that protrudes downward is provided at the center of the left and right of the lower surface 255 of the main body portion 250. The fitting protrusion 220 extends in a moving direction of the closing member 200 for mounting the closing member 200 to the slider body 100. The fitting projection 220 is a portion that is fitted to the fitting hole 75. The size of the fitting projection 220 in the left-right direction is smaller than the dimension of the main body portion 250 in the left-right direction. The lower surface 255 of the main body portion 250 is an arcuate surface that gradually extends upward from the side surfaces on the left and right sides of the fitting projection 220 toward the outer side in the left-right direction. The fitting protrusion 220 extends in the same direction as the direction in which the fitting hole 75 extends. The rear surface of the fitting protrusion 220 is in the same plane as the rear surface of the body portion 250 of the closing member 200, and the dimension of the fitting protrusion 220 in the front-rear direction is shorter than the dimension in the front-rear direction of the lower surface of the body portion 250. That is, the fitting protrusion 220 is provided at the rear end of the body portion 250 and its lower surface 255, and is not disposed across the entire front and rear lengths. When the fitting projection 220 is fitted into the fitting hole 75, the fitting projection 220 does not protrude further downward than the upper blade 10. Therefore, the movement of the fastener element is inhibited by the fitting projection 220.

As shown in FIG. 7, similarly to the relationship between the mounting portion 70 and the fitted hole 75, the length L220 of the fitting protrusion 220 is sufficiently short with respect to the front and rear length L250 of the main body portion 250 of the closing member 200. For example, the front and rear length L220 is 1/2 or less, or 1/3 or less, or 1/4 or less of L250.

Further, as shown in FIG. 9, the closing member 200 is not placed over the entire length of the mounting portion 70 in the front-rear direction. Further, the length L75 of the fitting hole 75 is shorter than the length L70' of the mounting portion 70 in the range in which the closing member 200 is placed.

The assembly method of the slider 400 with the pull tab will be described. First, the slider body 100, the closing member 200, and the pull tab 300 are prepared. Next, the pull tab 300 is attached to the pull tab mounting post 50 of the slider body 100. Specifically, the tab mounting post 50 is passed through the aperture 320 of the tab 300. Thereby, the pull tab 300 is detachably mounted relative to the pull tab mounting post 50. In this state, the pull tab 300 can be removed from the pull tab mounting post 50 via the gap 80 between the free end 52 of the tab mounting post 50 of the slider body 100 and the upper flap 10.

Next, in order to close the gap 80 between the tab mounting post 50 of the slider body 100 and the upper flap 10, the shutter member 100 is attached to the slider body 100. Specifically, the closing member 200 is inserted and disposed in the gap 80 between the engaging projection 60 and the upper blade 10. When the closing member 200 is disposed in the gap 80, the lower surface 255 of the body portion 250 of the closing member 200 is placed on the mounting surface 74 of the mounting portion 70 of the upper blade 10. When the closing member 200 is moved toward the base end portion 51 of the handle mounting post 50, the body portion 250 of the closing member 200 is guided by the mounting portion 70 and moves forward. At this time, since the placing portion 70 is an arcuate surface, even if the closing member 200 is inserted with a slight inclination, the closing member 200 is corrected to an optimum position or posture.

In the process of moving the closing member 200 toward the base end portion 51 of the tab mounting post 50 in the extending direction of the mounting portion 70, the pair of left and right claw portions 215 and the engaging projections 60 of the pair of right and left wall portions 210 of the closing member 200 The wide portion 61 collides. By moving the closing member 200 forward with sufficient force, the left and right intervals of the pair of right and left claw portions 215 are enlarged by the wide portion 61, and the pair of left and right wall portions 210 are also tilted so as to be inclined to the left and right.

When the pair of left and right claw portions 215 pass the wide portion 61 of the engaging projection 60, the pair of right and left wall portions 210 elastically return to the original shape, and the interval between the pair of left and right claw portions 215 also returns to the original interval. Thereby, the narrow portion 62 of the engaging projection 60 is sandwiched by the pair of right and left claw portions 215, and the locking surface 61d of the wide portion 61 faces the engaged surface 215c of the claw portion 215. By the engagement of the engaging projection 60 with the body portion 250, the closing member 200 can be prevented from coming off the slider body 100.

During the movement of the closing member 200 toward the front end portion 51 of the handle mounting post 50, the fitting projection 220 of the closing member 200 also moves forward, and is placed on the mounting surface 74 of the mounting portion 70. In a state where the lower surface 255 of the main body portion 250 of the closing member 200, the fitting projection 220 is inserted into and fitted into the fitting hole 75. The claw portion 215 passes through the wide portion 61, and the engaged surface 215c of the claw portion 215 is in surface contact with the locking surface 61d of the wide portion 61, and the fitting protrusion 220 and the fitted hole are completely synchronized or substantially synchronized therewith. The termination surface 75b of 75 is in surface contact. The point at which the engaged surface 215c of the claw portion 215 is in surface contact with the locking surface 61d of the wide portion 61 and the point at which the fitting projection 220 is in surface contact with the end surface 75b of the fitting hole 75 are completely or substantially the same.

The respective engaged surfaces 215c of the right and left claw portions 215 are in surface contact with the respective locking faces 61d of the wide portion 61 that are separated by the narrow portion 62. The narrow portion 62 is present between the left and right claw portions 215, so that the left and right displacement of the closing member 200 is restricted. By the engagement of the claw portion 215 with the wide portion 61, the rearward displacement of the closing member 200 is restricted. When the fitting projection 220 is fitted into the fitting hole 75, the fitting projection 220 restricts the displacement of the fitting projection 220 to the front and the left and right displacement.

The engagement protrusion 60 of the tab mounting post 50 and the upper flap 10 are limited by the restriction of the rearward displacement of the main body portion 250 by the engaging projection 60 and the displacement of the fitting projection 75 to the front of the fitting projection 220. The front and rear displacement of the closing member 200 between the placing portions 70 is restricted.

The restriction of the left and right displacement of the closing member 200 is ensured between the engaging projection 60 and the main body portion 250, and between the fitting projection 220 and the fitted hole 75. The restriction on the upper and lower displacement of the closing member 200 is ensured by the closing member 200 being sandwiched between the tab mounting post 50 and the upper flap 10. Specifically, the main body portion 250 is placed on the mounting portion 70 of the upper blade 10 to restrict displacement of the lower portion of the closing member 200. A pull tab mounting post 50 is present on the body portion 250 placed on the mounting portion 70 of the upper flap 10 to restrict displacement of the upper portion of the closure member 200. Further, the lower end portion 66 of the engaging projection 60 of the pull tab mounting post 50 is supported by the base portion 230 of the body portion 250 of the closing member 200 to restrict displacement of the upper portion of the closing member 200. Further, since the upper end portion of the wall portion 210 is in contact with the lower surface 52j of the free end portion 52 of the handle mounting post 50, the upper portion of the closing member 200 is also restricted from being displaced.

Based on the above teachings, various changes can be added to the respective embodiments as long as they are employees. The symbols added in the scope of the patent application are for reference and should not be used for the purpose of limiting the scope of the patent application.

The mounting portion 70 does not necessarily have to extend in parallel with respect to the front-rear direction, and may extend obliquely with respect to the front-rear direction. This point is also the same for the fitted hole 75.
