  • the lateral end of the first flange 16 comes into contact with the inner wall I, and the lateral end is slightly displaced upward. Due to this displacement, the lateral outer surface 16a and the inner wall I come into contact with each other in a substantially parallel state, and the contact area between the lateral outer surface 16a and the inner wall I can be increased. As a result, the frictional force between the side outer surface 16a and the inner wall I is improved, and the multi-cap 10 is prevented from floating.
  • the lateral outer surface 42a of the second flange 18 is a surface parallel to the vertical direction in the natural state, and as described above, the second flange 18 is inserted into the corresponding maximum diameter tube Tmax. Then, the side outer surface 42a and the inner wall I abut each other in a state of being substantially parallel. As a result, the frictional force between the side outer surface 42a and the inner wall I is improved, and the multi-cap 10 is prevented from floating.
  • the tip of the second flange 18 is formed with an inclined surface 42b that communicates with the upper side of the lateral outer surface 42a and faces laterally and upward (see FIG. 5).
  • the tube T is provided with a protrusion that protrudes inward from the inner wall I.
  • the protruding part may be a ridge extending all the way around the inner wall I of the tube T.
  • the second flange 18 is provided with the inclined surface 42b, the side end of the second flange 18 is more likely to be caught by the protrusion provided on the inner wall I.
  • the multi-cap 10 is prevented from floating by the second flange 18 being caught by the protruding portion.
  • the first flange 16 is protected by the action of the slit 30 or the groove 32.
  • Unexpected deformation is suppressed, and the unexpected deformation of the second flange 18 is suppressed by the bowl shape as a whole or by the elastic deformation of the strut 14 .
  • the multi-cap 10 is suppressed from floating.
  • the insertion force of the multi-cap 10 is determined by how easily the first flange 16 and the second flange 18 deform.
  • the slit 30 reduces the insertion force of the multi-cap 10 .
  • the groove 32 promotes upward deformation of the first flange 16 . That is, since the first flange 16 is easily deformed by the grooves 32, the insertion force of the multi-cap 10 is reduced by the grooves 32 as well.
  • the inner peripheral portion 40 of the second flange 18 is more difficult to deform upward than the outer peripheral portion 42 due to its extension direction. Therefore, if the inner circumferential portion 40 needs to be largely deformed upward in order to attach the multi-cap 10 to the corresponding minimum diameter tube Tmin, it can be said that a large insertion force is required.
  • the diameter L3 (see FIG. 5) of the inner peripheral portion 40 of the second flange 18 is smaller than the diameter of the corresponding minimum diameter tube Tmin.
  • the inner peripheral portion 40 does not reach the inner wall I, and even if the inner peripheral portion 40 does not largely deform upward, the multi-cap 10 can be moved to the corresponding minimum diameter tube. It can be attached to the tube Tmin.
  • the force for inserting the multi-cap 10 is also reduced because the diameter L3 of the inner peripheral portion 40 is smaller than the diameter of the corresponding minimum diameter tube Tmin.
  • the multi-cap 10 exhibits functions other than those described above.
  • the multi-cap 10 exhibits a centering function of bringing the multi-cap 10 closer to the center of the tube T in plan view.
  • the second flange 18 has a bowl shape as a whole, the centering function is exhibited.
  • the second flange 18 is inserted into the tube T through the opening O in a state where the second flange 18 is shifted from the center, the lower surface of the second flange 18 contacts the edge of the opening O. As shown in FIG.
  • the second flange 18 since the second flange 18 has a bowl shape, the second flange 18 receives a force from the edge of the opening O toward the center of the tube T. As shown in FIG. The multi-cap 10 is pushed toward the center of the tube T by this force.
  • the various configurations of the multi-cap 10 suppress unexpected deformation of the multi-cap 10 .
  • This exerts an individual difference suppressing function that absorbs individual differences in deformation of the multi-cap 10 due to dimensional variations among individual multi-caps 10 .
  • the first flange 16 can be deformed as expected in any multi-cap 10.
  • the second flange 18 has the above-described shape and that the dimension of the diameter L2 of the second flange 18 has some variation due to deformation in conjunction with the support 14.
  • any multi-cap 10 can cause the second flange 18 to deform as expected.

Abstract

L'invention concerne un bouchon multiple à bride qui peut correspondre à une large plage et qui peut prendre une posture appropriée lorsqu'il est fixé à un tube au sein de la plage correspondante.　Ce bouchon multiple (10) est conçu pour comprendre : une partie tête de bouchon multiple (12) ; une colonne de support (14) qui est allongée vers le bas à partir de la partie tête de bouchon (12) et qui présente une forme externe circulaire en coupe horizontale ; une première bride (16) annulaire qui fait saillie latéralement à partir de la surface latérale de la colonne de support (14) ; et une seconde bride (18) qui fait saillie latéralement à partir de la surface latérale de la colonne de support (14) à un emplacement situé au-dessous de la première bride (16). Lorsque le bouchon multiple (10) est fixé à un tube (T), les extrémités latérales de la première bride (16) et de la seconde bride (18) sont en contact avec une paroi interne (I) du tube (T). La première bride (16) présente une fente (30) découpée et pénétrant à travers cette dernière dans la direction verticale de façon à s'étendre dans la direction radiale de la première bride (16).
