And projects into the insertion space 3a. Further, as shown in FIG. 7, among the plurality of locking teeth 9 of the band-shaped portion 2 inserted into the insertion space 3 a, a predetermined locking tooth 9 is locked to the locking piece 3 g, and When the convex portion 5 is fitted into the concave portion 3f, the tip 3g2 of the locking piece 3g comes into contact with the second wall 3h. Further, as shown in FIG. 4, the center 3e1 of the extraction hole 3e is displaced from the center 3d1 of the insertion hole 3d toward the second wall 3h.

[Details of the seal band configuration]
Next, details of the configuration of the sealing band 1 will be described.
As shown in FIGS. 1 to 3, the belt-shaped portion 2 is formed in a thin and elongated belt-like shape, and a back surface 2a is provided with locking regions 2e in which a plurality of locking teeth 9 are formed at predetermined intervals. Has been. As shown in FIGS. 2 and 3, the locking teeth 9 are arranged along the longitudinal direction of the locking region 2e. As shown in FIG. 5, the locking teeth 9 are formed on the locking portion 9a locked to the tip 3g2 (FIG. 4) of the locking piece 3g and the tip (lower end in FIG. 5) of this locking portion 9a. It has a tooth tip 9b that is formed and an inclined portion 9c that is inclined from the tooth tip 9b toward the surface 2b. The addendum 9b is formed at an acute angle, and as shown in FIG. 3, the addendum surface of the addendum 9b is orthogonal to the back surface 2a. The locking teeth 9 are formed to have a height H, and the distance between the locking teeth 9 adjacent to each other is set to L. A bottom portion 9d parallel to the back surface 2a is formed between the locking teeth 9 adjacent to each other.

In other words, as shown in FIG. 5, each locking tooth 9 is formed in a sawtooth shape when viewed from the front. Further, the height H of each tooth tip 9b of each locking tooth 9 is set to a height that does not project from the back surface 2a of the band-shaped portion 2. Further, as shown in FIG. 3, the tooth tops 9b of the locking teeth 9 are formed to be slightly shorter than the width of the locking region 2e in the lateral direction. Further, as shown in FIG. 2, the locking region 2e in which the locking teeth 9 are arranged is formed thicker than the part other than the locking region 2e.

A protrusion 5 is formed on the surface 2b of the locking portion 9a. The convex portion 5 is a portion fitted into the concave portion 3f (FIG. 4) formed inside the head portion 3. When the convex portion 5 is fitted into the concave portion 3f, the belt-shaped portion 2 is pulled out to the drawing hole 3e. Therefore, it cannot be pulled out in the direction indicated by the symbol F in FIG. Further, a tag 4 is formed on the left side of the head 3 in the direction of the one end 2c of the strip portion 2. The tag 4 is formed in a thin rectangular plate shape, and on the front surface or the back surface of the tag 4, characters can be written or printed, or a sticker or the like can be attached. A through hole 8 for inserting a wire or a string is formed in the tag 4. In addition, an arrow-shaped cutting point indicating portion 6 is formed between the head portion 3 and the locking region 2e of the strip portion 2. The cut point instruction unit 6 indicates a cut point when the seal of the sealing band 1 is cut and released.

In this embodiment, the arrow of the cutting point designating section 6 points toward the head 3, and a cuttable area 2 f is formed between the head 3 and the cutting location designating section 6. When the seal of the sealing band 1 is cut and released, the cuttable area 2f is cut. Further, the other end 2d of the band-shaped portion 2 is provided with a non-slip region 2g. A plurality of anti-slip protrusions 7 are formed on the surface 2b of the anti-slip region 2g. Each of the anti-slip protrusions 7 is provided to prevent the other end 2d protruding from the pull-out hole 3e of the head 3 from slipping when being pinched and pulled out. Each of the anti-slip protrusions 7 is formed in a V shape with its top facing the direction of the other end 2d, and as shown in FIG.

As shown in FIG. 4, the head 3 is formed in a substantially trapezoidal shape when seen excluding the protrusion 3j formed on the back surface side, and the

outer surfaces

3m and 3n facing each other and the front surface 3p are formed. , And the back surface 3k. An insertion space 3 a for inserting the band-shaped portion 2 is formed inside the head 3. The back surface 3k is formed with an insertion hole 3d for inserting the other end 2d (FIG. 1) of the band-shaped portion 2, and the insertion hole 3d communicates with the insertion space 3a. That is, the insertion hole 3d forms an opening surface at one end of the insertion space 3a (an opening surface at the lower end in FIG. 4). In addition, a lead-out hole 3e for drawing out the other end 2d of the strip-shaped portion 2 inserted into the insertion space 3a is formed through the front surface 3p, and the lead-out hole 3e communicates with the insertion space 3a. That is, the extraction hole 3e forms an opening surface at the other end of the insertion space 3a (an opening surface at the upper end in FIG. 4).

The first wall 3b forming the insertion space 3a is provided with a concave portion 3f into which the convex portion 5 (FIGS. 1 and 2) of the belt-shaped portion 2 fits. Of the inner walls forming the recess 3f, the side surface 3f2 facing the insertion hole 3d is an opening surface communicating with the insertion hole 3d. As shown in FIG. 7, the convex portion 5 that has entered from the side surface 3f2 is fitted into the concave portion 3f, and the top portion 5a of the convex portion 5 abuts on the inner wall 3f3 of the concave portion 3f that faces the top portion 5a, so that An outer peripheral surface 5b of the outer peripheral surface of the portion 5 which faces the extraction hole 3e abuts on an inner wall 3f1 of the recess 3f which is located toward the extraction hole 3e. As a result, the movement of the convex portion 5 toward the extraction hole 3e, that is, the extraction of the strip portion 2 from the extraction hole 3e is prevented.

As shown in FIG. 4, a second wall 3h is formed inside the head 3 so as to face the first wall 3b with an insertion space 3a therebetween. A projecting portion 3c projecting into the insertion space 3a is formed at one end (lower end in FIG. 4) of the second wall 3h, and a locking piece 3g is formed at the projecting portion 3c. The locking piece 3g has a base portion 3g1 which is a portion of the overhanging portion 3c which is located toward the pull-out hole 3e. Further, the tip 3g2 of the locking piece 3g projects into the insertion space 3a toward the extraction hole 3e. A gap 3i is formed between the locking piece 3g and the second wall 3h.
The sealing band 1 of this embodiment is made of a synthetic resin such as nylon 66 or nylon 6, and the locking piece 3g has flexibility. Therefore, the locking piece 3g falls toward the second wall 3h when pressed by the locking teeth 9 of the belt-shaped portion 2, and returns to the pre-pressing posture when the pressing is released. That is, the locking piece 3g is swingable.

Also, the first wall 3b is formed in a tapered shape. In other words, the first wall 3b is inclined toward the extraction hole 3e. In this embodiment, the first wall 3b is formed substantially parallel to a virtual line V connecting the center 3d1 of the insertion hole 3d and the center 3e1 of the extraction hole 3e. Further, the second wall 3h is formed perpendicular to the extraction hole 3e. Therefore, as shown in FIG. 4, in the state where the strip-shaped portion 2 is not inserted into the insertion space 3a, the distance between the first wall 3b and the locking piece 3g is set from the base 3g1 to the tip 3g2 of the locking piece 3g. It gets narrower as you get closer to. Further, a vertical wall 3b2 formed vertically from the back surface 3k is formed at the end (the lower end in FIG. 4) of the insertion hole 3d of the first wall 3b. When the convex portion 5 of the band-shaped portion 2 passes through the side surface 3f2 which is the opening surface, the convex portion 5 advances between the vertical wall 3b2 and the vertical wall 3b2 and is fitted into the concave portion 3f. In FIG. 4, among the vertical walls 3b2 facing each other, only the cutting line of the vertical wall 3b2 located in the back of the drawing is drawn, and the cutting line of the vertical wall 3b2 existing in the front of the drawing is not shown. Further, each vertical wall 3b2 is orthogonal to each insertion hole 3d, and each surface of each vertical wall 3b2 exposed to the insertion space 3a is exposed to the insertion space 3a of the projecting portion 3c. It is parallel to the exposed surface.

Further, a protruding portion 3b1 protruding into the insertion space 3a is formed at an end portion (upper end portion in FIG. 4) of the first wall 3b toward the extraction hole 3e. As shown in FIGS. 6 and 7, the corner portion 3b3 at the lower end of the protruding portion 3b1 is formed so as to guide the strip-shaped portion 2 inserted from the insertion hole 3d to the extraction hole 3e while abutting the surface 2b thereof. Has been done. Further, the corner portion 3b3 at the lower end of the protruding portion 3b1 presses the surface 2b of the band-shaped portion 2 inserted into the insertion space 3a toward the locking piece 3g, and the locking portion 9a is brought into contact with the tip 3g2 of the locking piece 3g. It plays a role in locking. Further, as shown in FIG. 7, in the vertical wall 3b2 of the first wall 3b, the strip-shaped portion 2 located in the insertion space 3a is located closer to the insertion hole 3d than the projection 5 fitted into the recess 3f. Is formed so as to bend with the surface 2b1 of the above as the apex. In this embodiment, the band-shaped portion 2 is bent in a substantially V shape with the surface 2b1 of the first wall 3b, which is in contact with the vertical wall 3b2, as an apex.

In this way, by forcibly bending the strip-shaped portion 2, the stress generated by the bending can be applied to the convex portion 5, so that the convex portion 5 can be strongly pressed against the inner walls 3f1 and 3f3 of the concave portion 3f. Therefore, the fitting state of the convex portion 5 and the concave portion 3f can be firmly maintained.
Therefore, the fitting state of the convex portion 5 and the concave portion 3f is released, and there is no possibility that the strip portion 2 can be pulled out from the pull-out hole 3e.
That is, since the length of the strip-shaped portion 2 pulled out from the pull-out hole 3e can be kept constant, it can be estimated that someone has tried to release the seal when the length changes.
Further, the exposed surface of the overhanging portion 3c and the back surface 3k are orthogonal to each other. In this embodiment, each of the insertion hole 3d and the extraction hole 3e has a rectangular cross section.

[How to use the sealed band]
Next, a method of using the sealing band 1 will be described.
The other end 2d of the band-shaped portion 2 is inserted into a sealing band insertion hole provided in an object to be sealed (not shown). Then, the other end 2d inserted into the sealing band insertion hole is inserted from the insertion hole 3d of the head 3, and the other end 2d protruding from the extraction hole 3e is pulled out in the direction indicated by arrow F in FIG. When the non-slip region 2g (FIG. 1) in which the locking teeth 9 are not formed passes through the extraction hole 3e, the locking region 2e eventually reaches the insertion space 3a, and the plurality of locking teeth 9 in the locking region 2e. Of these, the first locking tooth 9 closest to the other end 2d is locked to the tip 3g2 of the locking piece 3g. When the belt-shaped portion 2 is further pulled out, the locked state between the first locking tooth 9 and the locking piece 3g, which were initially locked, is released, and the tooth tip 9b of the second locking tooth 9 is released. The locking piece 3g oscillates toward the second wall 2h by the pressing, and the tooth top 9b of the second locking tooth 9 faces the first wall 3b of each end edge of the locking piece 3g. When the end piece 3g5 is crossed over, the locking piece 3g returns to the position before the swing by the restoring force of the locking piece 3g and is locked with the second locking tooth 9. Thereafter, similarly, the locking and unlocking of the third and subsequent locking teeth 9 and the locking piece 3g are repeated.

Then, when the strip-shaped portion 2 is further pulled out, the convex portion 5 formed on the surface 2b of the strip-shaped portion 2 eventually enters from the side surface 3f2 of the concave portion 3f which is opened, is fitted into the concave portion 3f, and the convex portion 5 is recessed 3f. It abuts the inner walls 3f1 and 3f3 (FIG. 7). In other words, the convex portion 5 is in a state of being locked in the concave portion 3f. This makes it impossible to pull out the band-shaped portion 2 from the pull-out hole 3e. Furthermore, since the height of the convex portion 5 is higher than the depth of the concave portion 3f, when the convex portion 5 is fitted into the concave portion 3f, as shown in FIG. 7, the surface 2b of the belt-shaped portion 2 has the first wall. It will be in a state of being lifted from 3b. That is, the band-shaped portion 2 is pressed toward the locking piece 3g, and the tooth tops 9b of the locking teeth 9 pressing the sliding surface 3g3 of the locking piece 3g further move the locking piece 3g to the second wall. Press toward 3h. As a result, among the edges forming the tip 3g2 of the locking piece 3g, the edge 3g4 facing the second wall 3h is pressed against the second wall 3h, and the tip 3g2 of the locking piece 3g and the second edge 3g2. The gap 3i (FIG. 6) formed between the wall 3h and the wall 3h disappears.

Further, as shown in FIG. 7, the band-shaped portion 2 is bent in a dogleg shape with the surface 2b1 of the first wall 3b in contact with the vertical wall 3b2 as the apex. As a result, the convex portion 5 is pressed against the concave portion 3f more strongly, so that the fitted state of the convex portion 5 and the concave portion 3f is firmly maintained. Further, due to the stress generated by the bending of the strip-shaped portion 2, the strip-shaped portion 2 strongly presses the locking piece 3g, and the locking piece 3g is strongly pressed against the second wall 3h. As a result, the contact state between the edge 3g4 of the locking piece 3g and the second wall 3h is firmly maintained.
Further, as shown in FIG. 7, when the locking tooth 9 is locked to the locking piece 3g and the convex portion 5 is fitted to the concave portion 3f, the surface 2b of the belt-shaped portion 2 and the first portion 2b are brought into contact with each other. A space S is formed between the wall 3b and the wall 3b. As a result, even if an attempt is made to insert the tip of a tool such as a screwdriver from the pull-out hole 3e, press the inclined portion 9c of the locking tooth 9 and release the locked state of the locking tooth 9 and the locking piece 3g, Since the belt-shaped portion 2 is deformed and escapes into the space S, the locked state of the locking teeth 9 and the locking piece 3g cannot be released.
Therefore, the band-shaped portion 2 cannot be pulled out toward the insertion hole 3d, so that the sealing performance can be improved.

[Effect of Embodiment]
(1) When the sealing band 1 of the above-described embodiment is carried out, a predetermined locking tooth 9 among the plurality of locking teeth 9 of the band-shaped portion 2 inserted into the insertion space 3a in the head 3 is the locking piece. When the convex portion 5 of the strip-shaped portion 2 is fitted into the concave portion 3f of the first wall 3b, the tip 3g2 of the locking piece 3g is fixed to the third wall 3g and faces the first wall 3b. Since it comes into contact with the wall 3h of No. 3, even if an attempt is made to move the locking piece 3g toward the second wall 3h by inserting a pin or the like from the extraction hole 3e, the locking piece 3g cannot be moved. The locked state between the locking tooth 9 and the locking piece 3g cannot be released.
Moreover, since the convex portion 5 of the belt-shaped portion 2 is fitted into the concave portion 3f of the first wall 3b, it is possible to prevent the belt-shaped portion 2 from being pulled out from the pull-out hole 3e from that state. Can be increased.

(2) Further, among the plurality of locking teeth 9 of the band-shaped portion 2 inserted into the insertion space 3a, the locking tooth 9 facing the locking piece 3g comes into contact with the locking piece 3g, so that the insertion is performed. Even if a pin or the like is inserted through the hole 3d, the locking tooth 9 and the locking piece 3g that are in contact with the locking piece 3g prevent the pin or the like from entering, so that the locking tooth 9 and the locking piece 3g. The locked state with and cannot be released.
Therefore, the sealing performance can be further improved.

(3) Furthermore, since the distance between the first wall 3b and the locking piece 3g becomes narrower as it approaches the tip 3g2 from the base portion 3g1 of the locking piece 3g, the band-shaped portion 2 inserted from the insertion hole 3d is In the insertion space 3a, since the locking piece 3g formed on the second wall 3h can be pressed, the tip 3g2 of the locking piece 3g can be pressed against the second wall 3h.
Therefore, the state in which the tip 3g2 of the locking piece 3g is in contact with the second wall 3h can be firmly maintained, so that the sealing performance can be further improved.

(4) Further, since the center 3e1 of the extraction hole 3e is displaced from the center 3d1 of the insertion hole 3d toward the second wall 3h, the strip-shaped portion 2 inserted from the insertion hole 3d and extracted from the extraction hole 3e. Of these, the portion located in the insertion space 3a can be pressed against the locking piece 3g formed on the second wall 3h, so that the tip 3g2 of the locking piece 3g can be pressed strongly against the second wall 3h. ..
Therefore, the state in which the tip 3g2 of the locking piece 3g is in contact with the second wall 3h can be firmly maintained, so that the sealing performance can be further improved.

(5) Further, in the first wall 3b, the band-shaped portion 2 located in the insertion space 3a bends with the surface 2b1 of a predetermined portion closer to the insertion hole 3d than the convex portion 5 fitted in the concave portion 3f as an apex. Since it is formed as described above, the convex portion 5 can be pressed against the inner walls 3f1 and 3f3 of the concave portion, so that the fitted state of the convex portion 5 and the concave portion 3f can be firmly maintained.
Therefore, the fitting state of the convex portion 5 and the concave portion 3f is released, and there is no possibility that the strip portion 2 can be pulled out from the pull-out hole 3e.
That is, since the length of the strip-shaped portion 2 pulled out from the pull-out hole 3e can be kept constant, it can be estimated that someone has tried to release the seal when the length changes.

<Other Embodiments>
(1) The gap 3i (FIG. 4) formed between the locking piece 3g and the second wall 3h includes the thickness of the locking piece 3g, the shape of the locking piece 3g, the width of the insertion space 3a, and the band shape. The thickness of the portion 2, the height of the convex portion 5, the height H of the locking teeth 9 (FIG. 5), the depth of the concave portion 3f, and the like change. Therefore, when the locking teeth 9 are locked to the locking pieces 3g and the convex portions 5 are fitted into the concave portions 3f due to the design change of at least one of these numerical values. If the gap 3i occurs, the gap 3i can be eliminated by reviewing the above numerical values.
(2) When the protrusion 5 of the belt-shaped portion 2 is fitted into the recess 3f of the first wall 3b, if the situation where the locking tooth 9 is not locked to the locking piece 3g occurs The above situation occurs by changing at least one of the spacing L (FIG. 5) of the locking teeth 9, the number of the locking teeth 9, the forming position of the leading locking tooth 9 and the forming position of the convex portion 5. You can choose not to.
