Description

  The present invention relates to a hinge cap that can confirm an unopened state before use and can be disposed of after use.

  Some hinge caps have an annular fitting groove on the lower side and can be firmly fixed to the mouth of the container by plugging with the fitting groove. When performing, there is a problem that it is difficult to remove.

  For this reason, as a conventional hinge cap, on the outer periphery of the spout plug, two planned fracture portions are provided along the circumferential direction across the hinge coupling portion, and the portions partitioned by the planned fracture portion are hinge-coupled respectively. There is one that can be separated from the container mouth by forming a knob portion by breaking it into a band while pulling it to the portion, and then picking and pulling these knob portions together (see, for example, Patent Document 1) .

JP 2000-109112 A

  However, these conventional hinge caps for separation and disposal have taken measures against separation and disposal after use, but have not taken any measures to guarantee an unopened state before use.

  In addition, the conventional hinge cap has to be broken at two places in order to form a knob. For this reason, the waste disposal procedure is complicated and requires extra power.

  Therefore, if the thickness of the portion to be ruptured is made thin so as to be ruptured with a small force, each of the two portions to be ruptured extends in the circumferential direction from the lower end of the spout tap to the hinge connecting portion. For this reason, it is easy to cause breakage or elongation at the time of stoppering or when the internal pressure of high-temperature filling is increased, resulting in a disadvantage that the strength and sealing performance of the cap is lowered. In addition, if it is attempted to secure a large knob and easily apply the force, the cap is enlarged, which is disadvantageous in terms of production cost.

  An object of the present invention is to provide a hinge cap that can be easily separated and discarded while guaranteeing an unopened state before use.

The present invention includes an extraction stopper having an annular fitting groove fixedly held in the mouth portion of a container and provided with a dispensing portion in an inner region surrounded by the fitting groove, and the dispensing stopper.

The plate member that prevents the plate member is integrally provided via two breakable connecting pieces arranged at intervals in the circumferential direction, so that the plate member is deformed around the pressing portion of the plate member by pressing the plate member. The outer edge of each of the levers protrudes outward.

  In this invention, it is preferable to provide the flat part or hollow part which ensures the pushing allowance of the said plate member in the area | region part in which the press part of a plate member is located among the surrounding walls of a cover body.

  Moreover, it is preferable to provide the auxiliary | assistant protrusion which contacts the said plate member and causes the deformation | transformation by the press of a plate member in the surrounding wall of a cover body.

  Furthermore, a locking groove for removably hooking the outer edge of the plate member can be provided on the peripheral wall of the lid.

  In addition, a recess is formed in the peripheral wall of the lid, the protrusion is provided in the recess, the plate member is provided on the mating surface of the spout, and the plate member is provided in the recess provided in the peripheral wall of the lid. It is preferable that it can be stored.

  In the present invention, a vertical groove is formed on the outer peripheral surface of the spout tap downward from the mating surface with the lid, and the hinge connecting portion is crossed on the mating surface of the spout tap from a position close to the vertical groove. A circumferential groove can be formed, and a thin longitudinally-scheduled fracture portion extending in the longitudinal direction and a thin circumferentially-scheduled fracture portion extending in the circumferential direction starting from the longitudinally scheduled fracture portion can be provided.

  In the case where the fitting groove has an annular protrusion hooked on the mouth portion of the container on its outer peripheral surface, a vertical groove that divides the protrusion is formed, and the vertical groove and the vertical groove on the outer peripheral side are formed. A thin vertical portion to be broken in the vertical direction extending in the vertical direction can be provided therebetween.

  Further, in the present invention, a thin connection portion can be formed between the longitudinal groove and the lower end surface of the spout, and the connection portion can be configured as a radial break planned portion extending radially outward. .

  The circumferentially-scheduled portion can be configured such that the portion from the connecting portion with the longitudinal-direction scheduled portion to a predetermined range is thinner than the other portions, and the predetermined portion from the connecting portion with the longitudinal-direction scheduled portion It is also possible to form a cut at a portion in the range.

  The part in the predetermined range from the connection part with the circumferential direction fracture part can also be configured to be thinner than the other part, and the predetermined part from the connection part with the circumferential direction fracture part A cut can also be formed in the area. It is preferable to form the thin-walled portion and the cut at a portion adjacent to the circumferentially scheduled portion.

  Moreover, according to this invention, the thin part of the circumferential direction fracture | rupture planned part extended in the circumferential direction can also be provided in the mating surface of a pouring stopper.

  In addition, since the plate member is provided integrally with the spout plug via two breakable connecting pieces arranged at intervals in the circumferential direction, if the plate member is pressed, the plate member is pressed. The outer edge part protrudes outward centering on the part. For this reason, if a user picks and pulls the outer edge part of a plate member, two connection pieces will be cut | disconnected and a plate member can be isolate | separated from a pouring stopper. Thereby, the user can open the lid.

  That is, in the unopened state, the presence of the plate member makes it possible to visually recognize the unopened state, and when the lid is opened, the plate member is removed, The opened state can also be visually recognized. Therefore, according to this invention, the unopened state before use can be guaranteed.

  Further, in the present invention, when separating from the mouth portion of the container by separating the outer portion of the spout and opening the fitting groove, the separation is performed so as to circulate along the circumferentially scheduled fracture portion. Therefore, the force required for separation is relatively small. Moreover, the strength and sealing performance of the cap can be advantageously ensured.

  Further, since the separation is performed by pulling the lid, it is not necessary to separately provide a knob for removal. For this reason, by simplifying the configuration, the production cost can be reduced without increasing the size of the cap.

  Hereinafter, a hinge cap, which is an embodiment of the present invention, will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes a synthetic resin-made waste disposal hinge cap (hereinafter referred to as “hinge cap”), which is a first embodiment of the present invention, and reference numeral 2 denotes an extraction that constitutes the hinge cap 1. It is a stopper. As shown in FIG. 2, the spout 2 has an annular fitting groove n 0 that is fixedly held in the mouth portion 51 (hereinafter “container mouth portion”) 51 of the container 50. Reference numeral 3 denotes an extraction portion 3 provided integrally in an inner region surrounded by the fitting groove n0. The extraction part 3 has a cylindrical part, and the inside thereof is partitioned by a partition wall 4. In the partition wall 4, the stopper portion 4 a is partitioned by a thin planned breaking line L 0. A pull ring 5 is integrally provided in the stopper portion 4a.

  Reference numeral 6 denotes a lid that is rotatably connected via a hinge portion 7. The lid body 6 includes a top wall 6a disposed on the upper side of the pouring part 3 when fitted to the pouring stopper 2, and a peripheral wall 6b that hangs down from the outer edge of the top wall 6a. On the other hand, the spout 2 is integrally provided with an annular locking portion 2a so as to surround the spout 3. The peripheral wall 6b is detachably hooked and locked to the locking portion 2a. Thereby, as shown in the figure, the lid 6 is combined with the spout 2 to form a storage space R for the spout 3.

  Further, as shown in FIG. 3A, a recess 6c is provided in the peripheral wall 6b of the lid body 6. The recess 6 c is disposed at a position facing the connecting portion of the hinge portion 7. Moreover, the recessed part 6c comprises the notch-shaped thin part extended along the circumferential direction, and the two protrusions 6d are provided integrally. Each of the protrusions 6d is arranged at an interval in the circumferential direction. Each of the protrusions 6d is a claw-like protrusion, and its upper end surface 6d1 forms a flat surface.

  In addition, two auxiliary projections 6e are integrally provided in the recess 6c at a position inside the two projections 6d. Each of the auxiliary protrusions 6e extends in the vertical direction and is arranged at intervals in the circumferential direction. Furthermore, a flat portion 6f is formed between the auxiliary projections 6e in the recess 6c.

  Further, in FIG. 3B, reference numeral 8 denotes a plate member that is attached to the spout 2 and prevents the lid 6 from being opened. As shown in FIG. 1A, the plate member 8 is disposed in the concave portion 6 c of the lid body 6 when the lid body 6 is closed. As shown in the figure, the plate member 8 is formed with two notches A at intervals in the circumferential direction. An upper end surface 6d1 of a protrusion 6d provided on the lid 6 can be hooked on each of the notches A.

  Further, as shown in FIG. 3 (b), the plate member 8 is integrally provided on the mating surface 2 f with the lid body 6 via two connecting pieces 9. The connecting piece 9 is disposed at a position inside the two notches A at intervals in the circumferential direction. Thus, as shown in FIG. 4, when the lid 6 is closed after the lid 6 is open, the projection 6d is caught in the notch A as shown in FIG. The opening of 6 is blocked. 5 is a longitudinal sectional view of FIG.

  Further, as shown in FIG. 1, the peripheral wall 6b of the lid body 6 is provided with a locking groove 6g at each circumferential edge of the recess 6c. When each of the locking grooves 6g closes the lid 6, the outer edge portion 8e of the plate member 8 is caught as shown in FIG. As a result, the outer edge portion 8e does not protrude outward in a state where the outer edge portion 8e is housed in the recess 6c by closing the lid 6 as shown in FIG.

  In this way, if the plate member 8 is provided on the mating surface 2f of the spout 2 and the projection 6d of the lid 6 is hooked on the notch A of the plate member 8 to prevent the lid 6 from being opened, The lid body 6 cannot be opened unless the lid body 6 is intentionally pushed up with a relatively large force.

  Further, since the plate member 8 is provided integrally with the spout 2 via two connecting pieces 9 arranged at intervals in the circumferential direction, as shown in FIG. If the pressing part X of the plate member 8 located between the two is pressed, the outer edge part 8e is deformed around the pressing part X of the plate member 8 as shown in FIG. It can project outward.

  In the present embodiment, as described above, the two auxiliary projections 6e are provided in the concave portion 6c of the lid body 6 at intervals in the circumferential direction. Each of the auxiliary protrusions 6 e comes into contact with the back surface of the plate member 8 when the plate member 8 is pressed. At this time, if the two auxiliary protrusions 6e are further provided, the plate member 8 is largely inwardly deformed between the auxiliary protrusions 6e with the auxiliary protrusions 6e as a base point. As a result, the outer edge portion 8e of the plate member 8 protrudes greatly outward with the two auxiliary projections 6e as the base point. Therefore, it becomes easy to pick the outer edge portion 8e.

  In projecting the outer edge portion 8e outward, the outer edge portion 8e of the plate member 8 can be removed with a desired force by adjusting the groove depth of the locking groove portion 6g.

  Further, the connecting piece 9 can be broken by pulling the plate member 8. For this reason, if a user picks and pulls the outer edge part 8e, the two connection pieces 9 will be cut | disconnected, and as shown to FIG. Can do. Thereby, the user can open the lid 6.

  That is, in the unopened state, as shown in FIG. 1A, the presence of the plate member 8 makes it possible to visually recognize the unopened state, and the lid 6 is opened. In some cases, as shown in FIG. 1C, the plate member 8 is removed, so that the unsealed state can also be visually recognized.

  Therefore, according to this structure, the unopened state before use can be guaranteed.

  Moreover, if the plane part 6f is provided in the area | region part equivalent to the press part X of the plate member 8 among the surrounding walls 6b of the cover body 6 like this form, the press margin of the plate member 8 can be ensured. . The same applies to the case where a recessed portion is provided instead of the flat surface portion 6f.

  Further, as in the present embodiment, if a locking groove 6g is provided on the peripheral wall 6b of the lid 6 so that the outer edge portion 8e of the plate member 8 is removably hooked, the lid 6 is closed to be accommodated in the recess 6c. In this state, the outer edge portion 8e does not protrude outward as shown in FIG. In this case, as shown in the figure, the cap 1 gives a simple and clean appearance impression and can avoid the unexpected separation of the plate member 8.

  In this embodiment, as shown in FIG. 1 (a), the plate member 8 is housed in the recess 6c when the lid 6 is closed. Thus, even when the plate member 8 is housed in the recess 6c, the cap 1 gives a simple and clean appearance impression as shown in the figure, and it is possible to avoid unexpected separation of the plate member 8. it can.

  Further, as shown in FIG. 5, the spout 2 has an outer cylinder portion 21 that forms a fitting groove n0. The outer cylinder portion 21 is an outer portion of the spout 2. In FIG. 6A, reference numeral n 1 is an outer groove provided in the outer cylinder portion 21. The outer groove n1 is a vertical groove extending along the vertical direction (the axial direction of the extraction portion 3). The outer groove n1 is a V-shaped groove as shown in FIG. As shown in the enlarged portion of the figure, the outer cylinder portion 21 constitutes an end surface in which the separation start end surface 21a extends along the radial direction (direction perpendicular to the tangential direction), while the end surface 21b has a diameter of An end face inclined with respect to the direction (tangential direction) is formed.

  In FIG. 6 (b), reference numeral 10 denotes a longitudinal direction fracture portion provided in the outer cylinder portion 21. The longitudinal direction fracture | rupture plan part 10 becomes a starting point for cutting off the outer cylinder part 21 in a strip shape along the circumferential direction. As shown in the overall view of FIG. 6A, the longitudinally scheduled fracture portion 10 is provided in the vicinity of the connecting portion of the hinge portion 7 in the outer peripheral surface 2 s of the outer cylinder portion 21. Further, the longitudinal direction breaking portion 10 is formed as a thin connecting portion extending in the vertical direction between the fitting groove n0. Thereby, the longitudinal direction fracture | rupture scheduled part 10 forms a part of outer groove | channel n1, as shown in FIG.6 (b).

  Reference numeral 11 is also a portion to be broken in the vertical direction provided in the outer cylinder portion 21. The vertical direction fracture | rupture scheduled part 11 becomes a starting point for cut | disconnecting the outer cylinder part 21 to a strip shape along the circumferential direction with the vertical direction fracture | rupture scheduled part 10. As shown in the overall view of FIG. 6 (a), the longitudinal direction breakage portion 11 has a circumferential groove so as to cross the inside of the connecting portion with the hinge portion 7 from the position close to the outer groove n1. n2 is formed, and is formed as a thin connecting portion extending in the vertical direction between the circumferential groove n2 and the fitting groove n0. As a result, the longitudinally fractured portion 11, together with the longitudinally fractured portion 10, is one of the outer grooves n <b> 1 extending downward from the mating surface 2 f with the lid body 6, as shown in FIG. 6B. Forming part.

  Reference numeral 12 denotes a radial direction fracture portion provided in the outer cylinder portion 21. The radial direction fracture | rupture scheduled part 12 becomes a starting point for cut | disconnecting the outer cylinder part 21 in strip shape along the circumferential direction. Moreover, the radial direction fracture | rupture part 12 is formed as a thin connection part formed between the outer groove n1 and the lower end surface 2e of the extraction plug 2, as shown in FIG.6 (b). Thereby, the radial direction fracture | rupture planned part 12 also extends toward the radial direction outer side from the vertical direction fracture | rupture planned part 10, and forms a part of outer groove n1.

  In FIG. 7, reference numeral 13 denotes a circumferential direction fracture planned portion provided between the extraction portion 3 and the outer cylinder portion 21. The circumferential direction fracture | rupture scheduled part 13 becomes a starting point for cut | disconnecting the outer cylinder part 21 in strip shape along the circumferential direction. As shown in FIGS. 7 (a) to 7 (c), the circumferential breakage portion 13 is formed as a thin connecting portion extending in the circumferential direction between the circumferential groove n2 and the fitting groove n0. Thereby, the circumferential direction fracture | rupture scheduled part 13 forms a part of fitting groove n0 and the circumferential groove n2.

  Thus, while providing the longitudinal direction breakable parts 10 and 11 and the radial direction breakable part 12 in the pouring stopper 2, the circumferential direction breakable part 13 connected to the longitudinal direction breakable part 11 is provided on the mating surface 2f. If provided, when the user opens the lid 6 and pulls outward, as shown in FIG. 8, the outer tube portion 21 starts from the breakage from the longitudinally broken portions 10 to 12 as shown in FIG. 8. Are cut in the circumferential direction along the circumferentially scheduled fracture portion 13.

  According to this configuration, when separating from the container mouth portion 51 by separating the outer tube portion 21 of the spout 2 and opening the fitting groove n0, the separation is performed along the circumferentially fractured portion 13. Since it is performed so that it circulates, the force required for separation can be relatively small. Further, the separation is performed starting from the longitudinally fractured portion 10, and the outer peripheral inclined surface 52 of the container mouth portion 51 is below the locking portion 2 a until the separation is performed, as shown in FIG. 7. Since the inner periphery of the circumferentially scheduled portions 13a to 13c located at the inner periphery and the outer peripheral upper corner 21a of the fitting groove n0 formed above the circumferentially scheduled portions 13a to 13c are hermetically sealed, the cap The strength and sealability of No. 1 can be advantageously ensured, and in particular, the sealability is not impaired even when high temperature contents are filled.

  Furthermore, since the separation is performed by pulling the lid body 6, there is no need to separately provide a knob for removal. For this reason, by simplifying the configuration, the production cost can be reduced without increasing the size of the cap.

  Therefore, according to such a configuration, although it can be ruptured with a relatively small force, the procedure of separation and disposal is simple and the production cost is reduced without losing the strength and sealing performance or increasing the size of the cap 1. Can be suppressed.

  Further, in this embodiment, as shown in FIG. 7, the inner tube portion 22 is integrally provided on the spout tap 2 inside the outer tube portion 21 via the locking portion 2 a. The inner cylinder portion 22 functions as a seal portion that seals the inside of the container mouth portion 51.

  On the other hand, the outer cylinder portion 21 holds the container mouth portion 51 together with the inner cylinder portion 22, but in this embodiment, an annular protrusion 21p that is hooked on the container mouth portion 51 is integrally provided on the inner peripheral surface 21f. ing. For this reason, in this embodiment, as shown in FIG. 7, a vertical groove n3 for dividing the protrusion 21p in the vertical direction is formed. Thereby, the separation | separation which makes the longitudinal direction fracture | rupture scheduled part 10 a starting point can be performed with still smaller force.

  Moreover, in this embodiment, the longitudinal direction breaking portion 10 is configured to become thicker as it goes downward as shown in FIG. 7 (a). In this case, both ease of cutting and strength can be achieved.

  Further, in the present embodiment, a thin connecting portion is formed between the outer groove n1 and the lower end surface 2e of the spout tap 2, and the connecting portion is configured as a radial break planned portion 12 extending radially outward. As a result, the longitudinally-scheduled fracture portion 10 may be cut when a large force is applied to the spout 2 such as when the stopper is plugged while allowing the longitudinally-scheduled fracture portion 10 to be cut with a relatively small force. Reinforces to prevent breakage and serves to prevent unexpected cutting. Accordingly, both ease of cutting and strength can be achieved.

  Further, in this embodiment, the circumferential direction breaking portion 13 is configured such that the connecting portion C0 with the longitudinal direction breaking portions 10 and 11 has the thinnest thickness, as shown in FIG. 7 (a). . As a specific example, by arranging the fitting groove n0, the outer groove n1, and the circumferential groove n2 closest to each other, the thickness of the connecting portion C0 is made the thinnest. Thereby, cutting can be started with a small force.

  Furthermore, in this embodiment, the circumferential direction fracture portion 13 is a portion (hereinafter referred to as “cutting start portion”) from the connecting portion C0 to the longitudinal direction fracture portion 10 to a predetermined range as shown in FIG. ) 13a is configured to be as thin as the connecting portion C0. And it is comprised as the transition part 13b which becomes thick gradually from the part which crossed the center of the hinge part 7 as shown in FIG.7 (b). The transition portion 13b becomes thick radially outward to a predetermined range, but thereafter, the thickness thereof becomes constant at the steady portion 13c as shown in FIG. 7 (c).

  By providing the cutting start portion 13a (connecting portion C0), as shown in FIG. 8, the breakage easily proceeds and the lid body 6 is greatly separated from the spout 2. As described above, when the lid 6 is largely separated from the spout 2, it becomes easy to apply a force for pulling the lid 6. For this reason, even if the force required for cutting at the transition portion 13b increases, it can be cut relatively easily. Further, in the steady portion 13c, the strength of the cap 1 is increased and, as shown in FIG. 7C, the inclined surface 52 of the container mouth portion 51 remains in pressure contact, so that the sealing performance is not deteriorated.

  That is, if the cutting start portion 13a of the circumferentially scheduled portion 13 is configured to be thinner than the transition portion 13b and the steady portion 13c as in the present embodiment, the cutting start portion 13a is smoothly cut. On the other hand, the strength and sealability of the cap 1 can be ensured in the steady portion 13c. For this reason, it is preferable to ensure the range of the stationary part 13c wider than the cutting start part 13a.

  Moreover, the circumferential direction fracture | rupture scheduled part 13 can form a cut | interruption in the cutting | disconnection start part 13a. In this case, it becomes easier to start cutting the circumferentially scheduled portion 13. Further, with respect to the longitudinally scheduled fracture portion 11, a similar cut can be formed within a predetermined range from the connection portion (C 0) with the circumferential direction fracture scheduled portion 13. In addition, the longitudinal direction breaking portion 11 can also be configured so that a portion in a predetermined range from the connection portion (C0) with the circumferential direction breaking portion 13 is thinner than other portions.

  Further, according to the present invention, the following configuration can also be adopted as a means for sorting and discarding. In the following description, the plate member 8 is the same as that described above.

In this embodiment, the spout 2 is composed of a spout main body 2A and an outer cylinder portion 2B (21). The spout main body 2A is integrally formed with a spout 3 and has an annular fitting groove n0. An outer cylinder portion 21 that surrounds the dispensing body 2A at an interval is disposed in the dispensing plug body 2A, and the outer cylinder portion 21 is fixed to the dispensing portion 3 via a connection portion 23 that cannot be broken. The other portion of the outer cylinder portion 21 is connected to the extraction portion 3 through a plurality of connecting pieces 24 so as to be separable along the circumferential direction.

  More specifically, as shown in FIG. 10, the outer cylinder portion 21 is fixed to the extraction portion 3 through the fixed connecting portion 23 that cannot be broken at the opening side position of the lid body 6 that faces the hinge 7 side. In addition, the other portions are detachably connected via a plurality of connecting pieces 24 (only one place is shown in the drawing). Moreover, the outer cylinder part 21 is integrally connected with the extraction | pouring part 3 via the fixed connection part 23 provided in the lower end surface 2e of the extraction | pouring stopper 2, as shown in FIG. The dispensing part 3 is integrally formed with a fitting groove n0.

  According to this configuration, when separating and discarding, if the plurality of connecting pieces 24 are cut by pulling the lid body 6 upward, as shown in FIG. It remains connected with respect to the extraction | pouring part 3 leaving. Therefore, if the lid 6 is further pulled, the container cap 51 can be pulled out from the fitting groove n0, and the hinge cap 1 can be separated and discarded. In addition, the fixed connection part 23 can be connected with the extraction | pouring part 3 side in various positions, such as connecting the outer cylinder part 21 to the whole axial direction. Furthermore, the connecting piece 24 can also be configured as a thin strip-shaped portion.

  By the way, in the case of each form mentioned above, when the cover body 6 is opened, the protrusion 6d may get in the way. For this reason, according to this invention, a form as shown to FIGS. 13-14 is employable.

  In this embodiment, as shown in FIG. 13, when the lid body 6 is opened at the lower end of the lid body 6, the finger comes into contact with the dispensing part 3, and the protrusion is formed after the lid body 6 is opened. A tongue piece 6h for preventing contact with 6d is integrally provided. The tongue piece 6h is disposed between the two protrusions 6d as shown in FIG. 13 (a), and its tip hangs down from the peripheral wall 6b as shown in FIG. 13 (b). Further, as shown in FIG. 14 (a), the tongue piece 6h is accommodated in a slot hole 2b (see FIG. 14 (b)) formed in the mating surface 2f of the spout 2 when the lid 6 is closed. ing.

  In this embodiment, as shown in FIG. 14 (a), when the lid member 6 is opened after the plate member 8 is pushed in and removed, the tongue piece 6h is aligned with the lid member 6 as shown in FIG. 14 (b). It is located above the surface 6f. For this reason, when the cover body 6 is opened, it is possible to prevent the finger from coming into contact with the protrusion 6d.

  In this embodiment, the plate member 8 is formed as a handle only on one outer edge portion 8e, and is provided with a non-slip 8s. Further, in this embodiment, the outer cylinder portion 21 is poured out to the opening side position of the lid body 6 facing the hinge 7 through the fixed connection portion 23 that cannot be broken and extends in the entire axial direction, as in the conventional case. While being fixed to the part 3, the remainder is connected so that isolation | separation is possible via the fracture | rupture scheduled part.

  Even in such a configuration, when separating and discarding, the outer cylinder portion 21 is left with a fixed connection portion as shown in FIG. It remains connected to the outlet 3. Therefore, if the lid 6 is further pulled, the container cap 51 can be pulled out from the fitting groove n0, and the hinge cap 1 can be separated and discarded. In addition, although this part to be fractured is also configured as a thin strip-shaped part, it can also be configured by a plurality of connecting pieces arranged at intervals in the circumferential direction.

  The above description only shows one embodiment of the present invention, and various modifications can be made within the scope of the claims.
