  However, the conventional pouring container has room for improvement in suppressing the opening of the pouring hole due to the unexpected rotation of the operation member.

  This invention is made in view of the situation mentioned above, Comprising: It aims at providing the extraction cap which can suppress that an extraction hole is opened by the unexpected rotation of an operation member. To do.

In order to solve the above problems, the present invention proposes the following means.
The dispensing cap according to the present invention includes a mounting member that is mounted on the mouth portion of the container body that contains the contents, and an operation member that is mounted on the mounting member so as to be rotatable about the cap axis. A pouring cap whose pouring hole is opened and closed in accordance with the rotation of the operation member, wherein the mounting member includes a base tube portion extending in a cap axial direction, and the operation member is rotatable to the base tube portion And a pour member in which the pour hole is formed is provided inside the base tube portion and the rotary tube portion so as to be movable up and down in the cap axial direction. The mounting member or the operation member closes the pouring hole so as to be openable and closable, and the pouring member moves toward the upper side which is the side opposite to the container body along the cap axial direction. A plug that opens the hole is provided, and the dispensing member has a radial direction. Locking projections that protrude outward and are disposed in the first space formed in the base tube portion and in the second space formed in the rotating tube portion are provided on the wall surface that defines the first space. Is gradually extended upward as it goes from the closed side, which is one side in the circumferential direction, to the open side, which is the other side, and a guide wall that supports the locking projection, and an upper side from the closed end of the guide wall. A first regulating wall extending from the closed side to the locking projection in the storage state, and a wall that defines the second space has the locking projection in the storage state. wherein the engaging wall which engages from the open side sandwiching the locking projection in the circumferential direction between the first restriction wall, lockably formed from the closed side to the locking protrusion, the this for the operation wall spaced the closed side from the retaining projection in the storage state, it is provided The features.

In this invention, when the operation member is rotated toward the closed side in the circumferential direction, the locking wall of the rotating cylinder portion is locked to the first restriction wall of the mounting member via the locking protrusion. This rotation is restricted.
On the other hand, when the operating member is rotated toward the opening side in the circumferential direction, the operating wall approaches the locking projection while the locking wall of the operating member is separated from the locking projection to the open side. When the operation wall hits the locking projection and locks, the locking projection is pushed toward the open side in the circumferential direction by the operation wall and moves to the open side on the guide wall, and the dispensing member rotates with the operation member. To do. At this time, the locking protrusion is gradually raised along the guide wall, so that the pouring member is also raised along the cap axial direction, and the pouring hole is opened from the plug.
According to this pouring cap, when the operation member is rotated toward the opening side in the circumferential direction to open the pouring hole, after the operation wall is locked to the locking protrusion, the pouring member is connected to the operation member. The pouring hole is opened by ascending and rotating together. Therefore, until the operation wall is locked to the locking projection, it is possible to rotate the operation member without rotating the extraction member together with the operation member, and it is assumed that the operation member rotates somewhat unintentionally. Moreover, it can suppress that a pouring hole is opened unexpectedly.

Further, wherein the first wall defining a space, extends upward from the opening side end portion of the guide wall, while being lockably formed from the open side to the locking projection, wherein A second restriction wall may be provided that is spaced apart from the locking protrusion to the open side in the storage state .

In this case, when the operation member is rotated toward the open side in the circumferential direction and the extraction member is rotated together with the operation member, the operation wall moves the locking projection to the open end of the guide wall, Locking to the second restricting wall via the locking protrusion, as a result, further rotation of the operating member is restricted.
As described above, when the operation member is rotated toward the opening side in the circumferential direction, the operation wall is locked to the second restriction wall via the locking protrusion, thereby restricting further rotation of the operation member. Therefore, it is possible to suppress the operation member from rotating more than necessary, and the operability of the dispensing cap can be improved.

Further, wherein the second wall defining a space extending in a circumferential direction, the engaging wall and the operation wall each of the upper end portion connecting the connecting wall is provided, in the storage state, the locking projection The cap wall may be sandwiched between the closed end of the guide wall and the open end of the connection wall.

  In this case, since the locking projection is sandwiched between the closed end of the guide wall and the open end of the connection wall in the cap axial direction, the locking projection is locked to the first restriction wall. In the state of being sandwiched between the wall and the circumferential direction, it is possible to prevent the locking protrusion from inadvertently rattling in the cap axis direction and to prevent the pouring member from rising, and the pouring hole unexpectedly Opening can be suppressed.

In addition, the locking projection is rotated in the circumferential direction between the second restriction wall and the operation wall by rotating the operation member from the storage state to the open side. The guide wall may be clamped in the cap axial direction by the open end of the guide wall and the closed end of the connection wall.

  In this case, in a state where the operating member is rotated to the open side in the circumferential direction and the locking projection is sandwiched between the second restriction wall and the operating wall in the circumferential direction, the locking projection is located on the open side of the guide wall. Since it is clamped in the cap axial direction by the end and the closed end of the connection wall, it is possible to restrict the locking projections from rattling in the cap axial direction and ensure the opening of the pouring hole Can be made easier.

  The connection wall may gradually extend downward from the closed side toward the open side, which is the container body side along the cap axial direction.

In this case, when the operation member is rotated toward the opening side in the circumferential direction and the pouring hole is opened, the operation member is rotated toward the closing side in the circumferential direction to close the pouring hole again. While the operation wall of the operation member is spaced from the locking projection toward the closing side, the connection wall and the locking wall of the operation member sequentially abut against the locking projection from the open side in the circumferential direction. Then, the locking projection is gradually pushed toward the closed side in the circumferential direction by the connecting wall or the locking wall and moves on the guide wall to the closed side, so that the dispensing member rotates together with the operation member. At this time, the locking protrusion is gradually lowered along the guide wall, so that the pouring member is also lowered along the cap axial direction, and the plug closes the pouring hole.
In this way, after the pouring hole is opened, when the operating member is rotated toward the closed side in the circumferential direction in order to close the pouring hole again, the locking projection is formed by the connecting wall or the locking wall. Since it can be pushed in gradually, the locking projection can be smoothly moved on the guide wall, and the operability of the dispensing cap can be further improved.

  In addition, the operation member includes a top wall portion that covers the pouring member from above, and the pouring member moves up and down in the cap axial direction so that it protrudes and descends in the cap axial direction with respect to the top wall portion. Also good.

  In this case, the pouring member moves up and down in the cap axial direction, so that the pouring member moves up and down in the cap axial direction with respect to the top wall portion of the operation member. When the pouring member is raised and the pouring hole is opened without protruding from the portion, the pouring member can be protruded from the top wall portion. Therefore, it is possible to determine the open / closed state of the pouring hole by visually confirming the appearance of the pouring member with respect to the top wall portion from the outside, and the convenience of the pouring cap can be improved.

  According to the pouring cap according to the present invention, it is possible to suppress the opening of the pouring hole due to the unexpected rotation of the operation member.

  In the present embodiment, the first restriction wall 22 is locked to the locking projection 37 from the circumferential side D1 and the locking wall 29 is locked to the locking projection 37 from the circumferential side D2. Thus, a locking projection 37 is sandwiched between the first regulating wall 22 and the circumferential direction. The locking projection 37 is sandwiched between the end of the guide wall 21 on the closed side D1 in the circumferential direction and the end of the connection wall 31 on the open side D2 in the circumferential direction in the cap axis O direction.

  The second restricting wall 23 is formed so as to be able to be locked to the locking projection 37 from the circumferential open side D2, and is spaced from the locking projection 37 to the circumferential open side D2. Further, the operation wall 30 is formed to be able to be locked to the locking projection 37 from the circumferential side D1 and is spaced from the locking projection 37 to the circumferential side D1, and the upper end of the operation wall 30 is It is located above the lower end of the second restriction wall 23.

In the pouring cap 10, the pouring hole 36 is opened and closed with the rotation of the operation member 12. After the pouring hole 36 is opened, the contents in the container body B are poured out from the pouring hole 36. .
In the pouring cap 10, the stopper 14 is poured out as shown in FIG. 1 in a storage state in which the locking protrusion 37 is sandwiched between the first restricting wall 22 and the locking wall 29 in the circumferential direction. While closing the hole 36, the upper end of the pouring member 13 does not protrude from the upper surface of the top wall portion 24a of the operation member 12, and is not positioned above the upper surface of the top wall portion 24a but positioned below the upper surface. ing. When the operation member 12 is rotated toward the closed side D1 in the circumferential direction in the storage state as shown in FIGS. 1 and 9, the locking wall 29 of the rotating cylinder portion 26 is interposed via the locking protrusion 37. The rotation is restricted by engaging with the first restriction wall 22 of the mounting member 11.

  On the other hand, when the operating member 12 is rotated toward the opening side D2 in the circumferential direction in the storage cap 10 in the storage state, the locking wall 29 of the operating member 12 is separated from the locking projection 37 to the opening side D2. However, the operation wall 30 approaches the locking projection 37. When the operating member 12 is rotated about 90 degrees around the cap axis O from the storage state to the circumferential open side D2, as shown in FIG. .

  Then, the locking projection 37 is pushed by the operation wall 30 toward the open side D2 in the circumferential direction, gets over the ride-on projection 21a, moves on the guide wall 21 to the open side D2, and the dispensing member 13 and the operation member 12 Co-rotate. At this time, the locking protrusion 37 is gradually raised along the guide wall 21, so that the pouring member 13 also rises along the cap axis O direction as shown in FIG. The pouring hole 36 is opened from the plug body 14 in a state in which the cylindrical portion 33 protrudes from the top wall portion 24 a of the operation member 12 through the retracting hole 27.

  When the operation member 12 is rotated about 180 degrees around the cap axis O to the opening side D2 in the circumferential direction, the operation wall 30 opens the locking projection 37 in the guide wall 21 as shown in FIG. It moves to the end of the side D2 and is locked to the second restriction wall 23 via the locking protrusion 37, and the locking protrusion 37 is sandwiched between the second restriction wall 23 and the operation wall 30 in the circumferential direction. . As a result, further rotation of the operation member 12 is restricted. In this way, in the pouring cap 10 in the use state in which the locking projection 37 is sandwiched between the second restriction wall 23 and the operation wall 30, the locking projection 37 is the open side D <b> 2 in the guide wall 21. And the end of the connection wall 31 on the closed side D1 are sandwiched in the cap axis O direction.

  Thereafter, when the operation member 12 is rotated toward the circumferential side D1 in order to close the pouring hole 36 again, the operation wall 30 of the operation member 12 is disengaged from the locking projection 37 as shown in FIG. The connection wall 31 of the operation member 12 abuts against the locking protrusion 37 from the open side D2 in the circumferential direction while being separated toward the closing side D1. Then, the locking protrusion 37 is gradually pushed toward the closed side D <b> 1 in the circumferential direction by the connection wall 31, moves on the guide wall 21 to the closed side D <b> 1, and the extraction member 13 rotates together with the operation member 12. At this time, the locking projection 37 is gradually lowered along both the connection wall 31 and the guide wall 21, so that the pouring member 13 is also lowered along the direction of the cap axis O, and the plug body 14 is discharged from the pouring hole. 36 is closed.

  As shown in FIG. 9, the operation member 12 is continuously rotated toward the closed side D <b> 1 in the circumferential direction, and the locking wall 29 next to the connection wall 31 is locked to the locking protrusion 37, so that the locking protrusion 37. Is pushed into the closed side D1 in the circumferential direction, and the locking wall 29 is locked to the first regulating wall 22 of the mounting member 11 via the locking projection 37, so that the dispensing cap 10 is stored. Further rotation of the operation member 12 is restricted.

  As described above, according to the pouring cap 10 according to the present embodiment, the operation wall 30 is engaged when the operation member 12 is rotated toward the open side D2 in the circumferential direction in order to open the pouring hole 36. After being locked to the stop protrusion 37, the extraction member 13 is raised together with the operation member 12, so that the extraction hole 36 is opened. Therefore, until the operation wall 30 is locked to the locking protrusion 37, the operation member 12 can be idled without rotating the extraction member 13 together with the operation member 12. Even if it rotates unintentionally, it can suppress that the extraction hole 36 is opened unexpectedly.

Further, when the operation member 12 is rotated toward the opening side D <b> 2 in the circumferential direction, the operation wall 30 is locked to the second restriction wall 23 via the locking protrusion 37, thereby further increasing the operation member 12. Since the rotation can be restricted, it is possible to suppress the operation member 12 from rotating more than necessary, and the operability of the dispensing cap 10 can be improved.
Further, after the pouring hole 36 is opened, the locking projection 37 is moved by the connecting wall 31 when the operating member 12 is rotated toward the closing side D1 in the circumferential direction in order to close the pouring hole 36 again. Since it can be pushed in gradually, the locking projection 37 can be smoothly moved on the guide wall 21, and the operability of the dispensing cap 10 can be further improved.

  Further, since the pouring member 13 moves up and down in the cap axis O direction, the pouring member 13 appears and disappears in the cap axis O direction with respect to the top wall portion 24 a of the operation member 12. When the pouring member 13 is raised and the pouring hole 36 is opened without causing the member 13 to project from the top wall 24a, the pouring member 13 can be projected from the top wall 24a. Therefore, it is possible to determine the open / closed state of the pouring hole 36 by visually confirming the appearance of the pouring member 13 with respect to the top wall portion 24a from the outside, and the convenience of the pouring cap 10 can be improved. it can.

Further, in the storage state, the locking protrusion 37 is held in the cap axis O direction between the end of the guide wall 21 on the closed side D1 and the end of the connection wall 31 on the open side D2, so that the locking protrusion 37 37 can be prevented from inadvertently rattling in the direction of the cap axis O to prevent the pouring member 13 from rising, and the pouring hole 36 can be prevented from being opened unexpectedly.
Further, in the state of use, the locking projection 37 is sandwiched in the cap axis O direction by the end of the guide wall 21 on the open side D2 and the end of the connection wall 31 on the closed side D1, so that the locking projection 37 Can be controlled in the cap axis O direction, and the opening of the pouring hole 36 can be easily secured.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  In the said embodiment, although the extraction | pouring member 13 raises / lowers in the cap axis | shaft O direction, it protrudes / descends in the cap axis | shaft O direction with respect to the top wall part 24a of the operation member 12, but this invention is not limited to this. For example, when the pouring member rises, the pouring member does not have to protrude upward from the top wall portion.

  Moreover, in the said embodiment, although the connection wall 31 is gradually extended to the lower side which is the container body B side along the cap-axis O direction as it goes to the open side D2 from the closed side D1 of the circumferential direction, this invention It is not limited to this. For example, the connection wall may be formed in a straight line perpendicular to the cap axis in the side view. In this case, when the operating member is rotated toward the closed side in the circumferential direction to close the pouring hole, for example, the locking wall is locked to the locking protrusion from the open side, and the locking protrusion is It may be pushed toward the closing side.

  In the above embodiment, the locking projection 37 is sandwiched between the guide wall 21 and the connection wall 31 in the direction of the cap axis O in each of the storage state and the use state of the dispensing cap 10. Not limited. For example, the connection wall may be spaced upward from the locking projection.

  Moreover, in the said embodiment, although the 2nd space 28 is formed of the opening part which penetrates the rotation cylinder part 26 to radial direction, this invention is not limited to this. For example, the second space may not be opened toward the outside in the radial direction but may be opened only toward the inside in the radial direction. For example, you may form 2nd space by the ditch | groove part provided in the internal peripheral surface of a rotation cylinder part. Further, for example, a protruding portion may be formed on the inner peripheral surface of the rotating cylinder portion, and the locking space and the operation wall may be configured by the protruding portion to define the second space.

Moreover, in the said embodiment, although the rotation cylinder part 26 is extrapolated by the base cylinder part 18, this invention is not limited to this. For example, the rotating cylinder part may be inserted in the base cylinder part.
Furthermore, in the said embodiment, although the plug body 14 is provided in the mounting member 11, this invention is not limited to this. For example, the stopper may be provided on the operation member.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
