Description

  The present invention relates to a lid member and a container provided with the lid member.

  The lid member attached to the container body is disclosed in, for example, Patent Document 1. The lid member disclosed in Patent Literature 1 has a lid body having a liquid passage hole and a spout on the front end side and a gripping part on the rear end side for passing the liquid contained in the container body, A pouring lid for opening and closing the liquid hole and an operating member for locking the pouring lid in a closed state are provided.

  The pouring lid has a stopper for opening and closing the liquid passage hole. The stopper is in an open state in which the liquid passage hole is opened. The lid is attached to the lid main body so as to be rotatable about a rotation axis provided between the liquid passage hole and the grip portion in the lid main body between the closed state in which the liquid hole is closed. Further, the pouring lid includes an urging member for urging the opened pouring lid in the plugging direction.

  The operation member may be slidable in the front-rear direction between a position for locking the spout lid in a closed state and a position for unlocking the spout lid. It is attached to the rear side of the rotation shaft.

  Then, when the lid body is attached to the container body to pour out the liquid contained in the container body, for example, while grasping the grip portion, the operation member slidably attached to the pouring lid is moved backward with the thumb. Slide operation. As a result, the lock of the pouring lid is released, and the front part of the pouring lid is pivoted about the rotation axis by pressing down the rear portion of the pouring lid downward against the urging force. And the spout and the liquid passage hole are opened.

Is closed from above to be in a closed state.

Japanese Patent No. 6279278

  When the liquid is poured using the lid member disclosed in Patent Document 1, after sliding the operation member backward, the rear portion of the pouring lid is pressed downward against the urging force of the urging member. The lowering operation is performed, and the lid main body and the container main body are tilted while maintaining this state. Then, in the case where the liquid has been poured out, by stopping the operation of pushing down the pouring lid, the stopper is automatically rotated downward by the urging force of the urging member, and the liquid passage hole is closed. .

  Here, the user who has finished pouring the liquid may stop the operation of pushing down the pouring lid in a state where the lid main body and the container main body are inclined so that the liquid does not flow out of the spout. In this case, the liquid may be trapped in a state where the liquid has accumulated between the spout of the lid main body and the front part of the pouring lid. The liquid confined between the spout and the pouring lid may spill unexpectedly from between the spout and the pouring lid when the lid member is tilted, for example, when it is taken in and out of the refrigerator. There is a risk of coming out.

  Assuming such a case, it is conceivable to omit the urging member. In this case, the liquid hole cannot be closed unless the user applies a force in the closing direction to the front part of the pouring lid, and the liquid hole is closed with the lid member inclined as described above. Can be suppressed.

  However, when the urging member is omitted, there is a problem that it is difficult to operate the pouring lid in the closing direction with one hand. Specifically, in the lid member described in Patent Literature 1, it is necessary to operate the rear part of the pouring lid upward in order to close the liquid passage hole, but the upper surface of the rear part of the pouring lid is formed in an arc shape. It is difficult to apply an upward force. Here, it is conceivable to use the force for moving the operation member in the locking direction to operate the rear part of the pouring lid upward, but the operation of the operation member in the locking direction is forward, and the operation member is operated. And the rotation axis of the pouring lid are at substantially the same height, it is difficult to convert the force for operating the operation member into the force in the rotation direction of the rotation axis.

  An object of the present invention is to provide a lid member and a container capable of smoothly rotating a pouring lid in a closing direction by operating an operation member.

  In order to solve the above-mentioned problem, the present invention is a lid member attached to a container body, for pouring a liquid introduced from the liquid passage hole and a liquid passage hole for passing a liquid contained in the container body. A lid body having a spout, and a stopper for opening and closing the liquid passage hole, wherein the stopper part opens the liquid passage hole, and covers the spout from above, and A spout lid attached to the lid body so as to be rotatable about a first rotation axis between a stopper portion in which the stopper portion closes the liquid passage hole, and the first rotation axis. A lock position for locking the pouring lid in the closed state, which is provided on a side opposite to the stopper as a reference, and moves in a direction away from the stopper than the lock position to release the lock. Between the release position and the second rotation axis parallel to the first rotation axis. An operation member rotatably attached to the lid main body, wherein the operation member is configured to rotate the first rotation axis of the pouring lid in the closed state in a state of being rotated to the lock position. The center of the second rotation axis from the lock position to the release position while contacting the contact surface of the pouring lid so as to restrict the rotation to the open state around the center. A contact surface formed so as to be separated from the contacted surface in accordance with the rotation of the operation member; and a rotation of the operation member around the second rotation axis from the release position to the lock position. The closing side of the spout lid so as to transmit the turning force of the operation member to the spout lid as a force for turning the spout lid from the open state to the closed state. A cover member having a closed-side transmitting surface that contacts the transmitted surface. To.

  Further, the present invention provides a container comprising: any one of the lid members described above; and a container body to which the lid member is attached.

  According to the present invention, by rotating the operation member about the second rotation axis from the release position to the lock position, the operation member is rotated using the rotation force of the operation member via the closing-side transmission surface. The outlet cover can be turned from the open state to the closed state. Here, since the operation member is rotated about a second rotation axis different from the first rotation axis which is the center of rotation of the spout lid, the turning force of the operation member is used for spouting. It is possible to efficiently transmit the rotation force of the lid to the pouring lid. Therefore, the pouring lid can be smoothly turned in the closing direction by the turning operation of the operating member from the release position to the lock position.

  Therefore, in order to prevent the liquid from being abruptly trapped between the spout of the lid body and the pouring lid, the urging member for urging the pouring lid to the closed state is omitted. Even if there is, the pouring lid can be easily closed by rotating the operation member from the release position to the lock position.

  In the cover member, the operation member may be configured to reduce the turning force of the operation member with the rotation of the operation member about the second rotation axis from the lock position to the release position in the closed state. An opening-side transmission surface that comes into contact with the opening-side transmission surface of the pouring lid so as to transmit to the pouring lid as a force for rotating the pouring lid from the open state to the open state. Is preferred.

  According to this aspect, by rotating the operating member from the lock position to the release position, the force of this rotation is transmitted to the pouring lid via the open-side transmission surface, and the pouring lid is opened. It can rotate from the state to the closed state. Therefore, the opening operation of the pouring lid can be smoothly performed using the operation member.

  In the lid member, it is preferable that the opening-side transmission surface is provided at a position separated from the opening-side transmission surface in a state where the operation member is rotated to the lock position.

  According to this aspect, it is possible to prevent the force in the opening direction from being transmitted from the operating member to the pouring lid via the opening-side transmission surface when the operating member is rotated to the lock position. Thus, the pouring lid can be reliably maintained in the closed state.

  In the lid member, it is preferable that the operation member includes a sliding surface that comes into contact with a sliding surface of the lid main body over the entire range of rotation between the lock position and the release position.

  According to this aspect, sliding resistance can be applied to the operation member in the entire range of the rotation of the operation member between the lock position and the release position. Thus, even if the user releases his / her hand from the operation member, the rotation of the operation member is stopped at that time, and thus the rotation of the pouring lid using the turning force of the operation member is also stopped. Therefore, it is possible to prevent the spout lid from unexpectedly turning when the user releases his / her hand from the operation member.

  In the lid member, at least one of the sliding surface and the slid surface has a contact pressure between the sliding surface and the slid surface when the operating member is rotated to the lock position. It is preferable to have a shape that is smaller than the contact pressure when the operating member is rotated from the position toward the release position.

  According to this aspect, when the operating member rotates from the release position toward the lock position and reaches the lock position, it is possible to give the user a feeling of release from sliding resistance, that is, a click feeling. it can. Therefore, it is possible to inform the user that the operation member is at the lock position as a touch.

  In the lid member, the contact surface and the contacted surface are centered on a radial direction about the first rotation axis and the second rotation axis when the operation member is rotated to the lock position. It preferably extends along both tangential directions.

  According to this aspect, when an external force in the direction of opening the pouring lid is applied in a state where the operation member is rotated to the lock position, the force transmitted from the contacted surface to the contact surface is the second rotation shaft. , The operation member is unlikely to rotate around the second rotation axis due to the force in the direction along the straight line passing through the operation member. Therefore, the closed state of the pouring lid can be reliably maintained.

  On the other hand, the contact surface and the contact surface extend in the tangential direction of the second rotation axis when the operation member is rotated to the lock position, so that the operation member is moved to the release position about the second rotation axis. The contacted surface and the contact surface can be separated from each other while sliding toward each other. Therefore, rotation of the operation member from the lock position to the allowable position is permitted.

  In the lid member, the pouring lid is an elastic portion having the contact surface, and the operation member rotates about the second rotation axis from the lock position to the release position. It is preferable that the contact surface includes an elastic portion that elastically deforms in a direction away from the contact surface according to a force received from the contact surface.

  When the relative displacement between the contact surface and the contact surface during rotation of the operation member from the lock position to the release position is realized only by sliding between the contact surface and the contact surface, the wear of the contact surface and the contact surface may cause the lid member to have a long term. Use may be difficult. Therefore, by providing the contact surface on the elastic portion as in the above embodiment, the lid member can be used longer.

  In the lid member, the operation member may be configured such that, when the operation member is turned to the lock position, the dispensing operation is performed such that a force for pressing the dispensing lid in a closing direction is transmitted to the dispensing lid. It is preferable to have a pressing surface for pressing the pressed surface of the lid.

  According to this aspect, since the pouring lid can be pressed in the closing direction in a state where the operation member is rotated to the lock position, the pouring lid can be reliably maintained in the closed state.

  By operating the operation member, the spout lid can be smoothly rotated.

It comes into contact with the closed-side transmitted surface 452 of the pouring lid 4 so as to transmit the force for rotating the pouring lid 4 to the pouring lid 4. Specifically, the closing-side transmission surface 52b is provided on a protruding piece 50d that protrudes forward from the front surfaces of the two support legs 50c. The protruding piece 50d has a triangular shape having a vertex forward in a side view. The closing-side transmission surface 52b is provided at the tip (front end) of the protruding piece 50d.

  The contact surface 53 controls the rotation of the pouring lid 4 in the closed state in the state where the pouring lid 4 is rotated to the lock position, about the first pivot shaft 34a to the open state. To the contact surface 44 of the contact. The contact surface 53 is formed so as to be separated from the contact surface 44 in accordance with the rotation of the operation member 5 about the second connected portion 56 from the lock position to the release position. Specifically, the contact surface 53 is the upper surface of the protruding piece 50d formed on each of the two support legs 50c. Further, as shown in FIG. 2, when the operation member 5 is rotated to the lock position, the contact surface 53 has a radial direction p around the first rotation shaft 34a and a second connected portion 56 (second connection portion 56). (Rotation axis) and extends in both tangential directions q.

  The pressing surface 54 is a pressed surface of the pouring lid 4 such that a force for pressing the pouring lid 4 in the closing direction is transmitted to the pouring lid 4 when the operating member 5 is rotated to the lock position. Press 46. Specifically, the pressing surface 54 is a portion of the front surface of each of the two support legs 50c above the protruding piece 50d.

  The sliding portion 55 extends toward the second connected portion 56 (inside) from between the two support legs 50c on the lower surface of the covering portion 50a. The sliding portion 55 is a sliding surface that contacts the upper surface (slidable surface) of the sliding portion 36 of the lid body 3 over the entire range of rotation of the operation member 5 between the lock position and the release position. (Signs omitted). The sliding surface is a portion of the lower surface of the sliding portion 55 closest to the second connected portion 56. As shown in FIG. 2, the distance L2 from the sliding surface of the sliding portion 55 to the second connected portion 56 (second rotation axis) is the first sliding of the lid body 3 from the second connected portion 56. The radius of curvature r1 of the moving portion 36a is set to be smaller than the radius of curvature r2 of the second slidable portion 36b.

  Thereby, when the sliding surface of the sliding portion 55 slides on the upper surface (the sliding surface) of the first sliding portion 36a, a sliding resistance is generated, and a force from the user is applied to the operating member 5. The rotation position of the first slidable portion 36a in a state where it is not performed can be held.

  Here, the contact pressure between the sliding surface and the sliding surface when the operating member 5 is rotated to the lock position causes the operating member 5 to rotate from the lock position to the release position. The radius of curvature r2 is set smaller than the radius of curvature r1 so as to be smaller than the contact pressure in the moving state. Therefore, when the operating member 5 is rotated to the lock position, the sliding resistance is smaller than the sliding resistance up to that point, and the user recognizes that the operating member 5 has been rotated to the locked position as a click feeling. Can be.

  Since the second connected portion 56 is supported by the second support portion 35 of the lid main body 3, the operation member 5 rotates around the second connected portion 56 (second rotation axis) of the lid main body 3. The operating member 5 can be attached to the lid body 3 so as to be possible.

  Next, the operation of the container 10 of the present invention will be described. Description will be made from the closed state shown in FIGS. 1 and 2. When the liquid stored in the container body 1 is to be poured out, for example, the grip portion 33 is gripped, and the operation member 5 is pulled away from the plug portion 42 with the thumb of the gripped hand.

  Thus, the operation member 5 starts to rotate clockwise in FIGS. 1 and 2 around the second connected portion 56 (second rotation axis). With the rotation, as shown in FIG. 10, the contact object of the sliding portion 55 of the operating member 5 is changed from the second sliding portion 36b of the sliding portion 36 of the lid body 3 to the first sliding portion 36a. Changes to Further, the contact surface 53 of the operation member 5 moves away from the contact surface 44 while sliding with respect to the contact surface 44 of the pouring lid 4. Further, the pressing surface 54 is separated from the pressed surface 46 of the pouring lid 4. Further, with the rotation of the operation member 5, the opening side transmission surface 52a of the operation member 5 comes into contact with the opening side transmission surface 451 of the pouring lid 4, and the force for rotating the operation member 5 is discharged. The force for rotating the lid 4 is transmitted to the pouring lid 4.

  Specifically, the opening-side transmitted surface 451 of the pouring lid 4 is pressed downward by the opening-side transmitting surface 52a of the operation member 5, whereby the pouring lid 4 is centered on the first rotating shaft 34a. And starts rotating clockwise in FIG.

  Since the operation member 5 rotates around a second connected portion 56 (second rotation shaft) different from the rotation center (first rotation shaft 34a) of the pouring lid 4, the operation member 5 The turning force can be efficiently transmitted to the pouring lid as the turning force of the pouring lid. Thus, the spout lid can be smoothly turned by the turning operation of the operation member.

  When the operated portion 51 of the operating member 5 is further rotated rearward, as shown in FIG. 11, the open-side transmitting surface 52a of the operating member 5 moves the open-side transmitted surface 451 of the pouring lid 4 downward and rearward. Move while pressing. Thereby, the stopper 42 comes out of the liquid passage hole 31c.

  In the course of this rotation, since the closed-side transmitting surface 52b of the operating member 5 receives the closed-side transmitted surface 452 of the pouring lid 4 from below, the open-side transmitting surface 52a of the operating member 5 is used for pouring. It is possible to prevent the lid 4 from separating from the open-side transmitted surface 451.

  Then, as shown in FIG. 12, when the sliding portion 55 of the operating member 5 reaches the end of the first slidable portion 36a of the lid main body 3, the rotation of the operating member 5 stops, and as a result, The rotation of the lid 4 stops. In this state, the stopper 42 of the pouring lid 4 is separated from the liquid passage hole 31c of the lid main body 3, and the pouring lid main body 41 of the pouring lid 4 is moved to the pouring opening 31d of the lid main body 3. Is opened to open. In this state, the liquid stored in the container body 1 can be poured out from the liquid hole 31c and can be poured from the spout 31d.

  Here, sliding resistance is generated between the sliding portion 55 and the first slidable portion 36a of the lid body 3. Therefore, even if the user releases his / her hand from the operated portion 51 of the operation member 5, the opened state is maintained by holding the position of the pouring lid 4 using the force of the sliding resistance. Can be. In addition, since sliding resistance occurs between the sliding portion 55 and the first slidable portion 36a of the lid main body 3 over a range of rotation between the lock position and the release position of the operation member 5, it is used for pouring. Even when the lid 4 is in the middle of rotation (for example, the position shown in FIGS. 10 and 11 described above), the position of the pouring lid 4 can be held.

  In the case of plugging, contrary to the above, the operated portion 51 of the operating member 5 is rotated upward and forward from the state shown in FIG. As a result, the closing-side transmitting surface 52b of the operating member 5 contacts the closing-side transmitted surface 452 of the pouring lid 4 from below, and the force for rotating the operating member 5 is directed to the pouring lid 4 in the closed state. The rotation force can be transmitted to the pouring lid 4. That is, the pouring lid 4 starts rotating counterclockwise in FIG.

  Also when the operation member 5 is rotated, the operation member 5 is centered on a second connected portion 56 (second rotation axis) different from the rotation center of the pouring lid 4 (first rotation axis 34a). To rotate. Therefore, the turning force of the operating member 5 can be efficiently transmitted to the pouring lid as a rotating force in the direction in which the pouring lid 4 opens, and the turning force in the closing direction of the pouring lid 4 can be obtained. it can.

  Further, when the operated portion 51 of the operating member 5 is rotated upward and forward, as shown in FIG. 11, the closing-side transmitting surface 52b of the operating member 5 moves the closing-side transmitting surface 452 of the pouring lid 4. Press upward and forward. Thereby, the pouring lid 4 further rotates counterclockwise about the first rotating shaft 34a.

  Also, in the course of this rotation, the open-side transmitting surface 52a of the operating member 5 is in contact with the opening-side transmitted surface 451 of the pouring lid 4 from above. It is possible to prevent the lid 4 from being separated from the closed-side transmitted surface 452.

  When the pouring lid 4 further rotates counterclockwise about the first rotating shaft 34a, as shown in FIGS. 1 and 2, the sliding target 55 of the operating member 5 contacts the lid main body. The third slidable portion 36 of the third slidable portion 36 is changed to a second slidable portion 36b. As a result, the user can recognize that the plug has been closed with a click feeling.

  In this state, the stopper 42 is in close contact with the edge of the liquid passage hole 31c to seal the liquid passage hole 31c, and the pouring lid body 41 is in a closed state in which the spout 31d covers the spout 31d from above.

  In this closed state, the contact surface 53 of the operation member 5 and the contact surface 44 of the pouring lid 4 come into surface contact. In this state, the contact surface 53 and the contact surface 44 are both in the radial direction p about the first rotation axis 34a and in the tangential direction q about the second connected portion 56 (second rotation axis). Is formed so as to extend along. Therefore, even when, for example, a turning force is applied to the pouring lid 4 in a direction to open from the outside, the contact surface 44 and the contact surface 53 have a normal line toward the second connected portion 56 (second rotation axis). The force in the direction is applied, and the force transmitted from the pouring lid 4 to the operation member 5 can be suppressed from acting as the rotational force of the operation member 5. Therefore, even if a force in the direction of opening is applied to the closed spout 4, the operation member 5 is rotated by the force, and thus the spout 4 is rotated about the first pivot shaft 34 a. The movement can be regulated, and as a result, the spouting lid 4 in the closed state can be locked.

  As described above, by rotating the operation member 5 about the second connected portion 56 from the release position to the lock position, the force of the rotation of the operation member 5 via the closing-side transmission surface 52b is provided. Can be used to rotate the pouring lid 4 from the open state to the closed state. Here, since the operation member 5 rotates around the second connected portion 56 different from the first rotation shaft 34a which is the center of rotation of the pouring lid 4, the rotation of the operation member 5 is prevented. The force can be efficiently transmitted to the pouring lid 4 as the turning force of the pouring lid 4. Therefore, the pouring lid 4 can be smoothly turned in the closing direction by the turning operation of the operating member 5 from the release position to the lock position.

  Therefore, in order to prevent the liquid from being abruptly trapped between the spout 31d of the lid body 3 and the pouring lid 4, an urging member for urging the pouring lid 4 to the closed state is provided. Even if it is omitted, the pouring lid 4 can be easily closed by rotating the operating member 5 from the release position to the lock position.

  Further, according to the embodiment, the following effects can be obtained.

  By rotating the operation member 5 from the lock position to the release position, the force of this rotation is transmitted to the pouring lid 4 via the opening-side transmission surface 52a, and the pouring lid 4 is moved from the open state. It can rotate to the closed state. Therefore, the opening operation of the pouring lid 4 can be smoothly performed using the operation member 5.

  When the operating member 5 is turned to the lock position, the force in the opening direction can be prevented from being transmitted from the operating member 5 to the pouring lid 4 via the opening-side transmission surface 52a. The outlet cover 4 can be reliably maintained in the closed state.

  Sliding resistance can be given to the operation member 5 in the entire range of rotation of the operation member 5 between the lock position and the release position. Thereby, even if the user releases his / her hand from the operation member 5, the rotation of the operation member 5 is stopped at that point, so that the rotation of the pouring lid 4 using the turning power of the operation member 5 is also prevented. Stopped. Therefore, it is possible to prevent the spouting lid 4 from unexpectedly turning when the user removes his / her hand from the operation member 5.

  When the operating member 5 rotates from the release position to the lock position and reaches the lock position, the user can be given a feeling of release from sliding resistance, that is, a click feeling. Therefore, it is possible to inform the user that the operation member 5 is at the locked position as a touch.

  When an external force in the direction of opening the pouring lid 4 is applied while the operation member 5 is rotated to the lock position, the force transmitted from the contact surface 44 to the contact surface 53 causes the second connected portion 56 to move. Since the force is in the direction along the passing straight line, the rotation of the operation member 5 around the second connected portion 56 by this force is unlikely to occur. Therefore, the closed state of the pouring lid 4 can be reliably maintained.

  On the other hand, since the contact surface 44 and the contact surface 53 extend in the tangential direction of the second connected portion 56 in a state where the operating member 5 is rotated to the lock position, the operating member 5 is moved to the second connected portion. By rotating around the 56 toward the release position, the contact surface 44 and the contact surface 53 can be separated from each other while sliding. Therefore, rotation of the operation member 5 from the lock position to the allowable position is allowed.

  In the above-described embodiment, the pouring lid 4 is an elastic piece 47 having the contact surface 44, and is rotated by turning the operation member 5 about the second connected portion 56 from the lock position to the release position. The contact surface 44 includes an elastic piece 47 that elastically deforms in a direction away from the contact surface 53 in accordance with a force received from the contact surface 53.

  When the relative displacement between the contact surface 44 and the contact surface 53 at the time of rotation of the operation member 5 from the lock position to the release position is realized only by sliding of both, the wear of the contact surface 44 and the contact surface 53 causes Long-term use of the lid member 2 may be difficult. Therefore, by providing the contact surface 44 on the elastic piece 47, the lid member can be used longer.

  Since the pouring lid 4 can be pressed in the closing direction in a state where the operation member 5 is rotated to the lock position, the pouring lid 4 can be reliably maintained in the closed state.

  In the above embodiment, the urging member for urging in the direction of closing the pouring lid 4 is omitted, but an urging member may be provided. Even when the urging member is provided, the urging member is adjusted by adjusting the sliding resistance when the sliding portion 55 of the operation member 5 slides on the first slidable portion 36a of the lid body 3. The turning position of the pouring lid 4 can be held only by the biasing force of (1).

  In the above-described embodiment, the configuration has been described in which the operating member 5 is provided with the sliding portion 55 protruding from the operated portion 51 and the lid main body 3 is provided with the sliding portion 36 having two curvature radii r1 and r2. However, means for causing the user to recognize that the pouring lid 4 is in the closed state (the operation member 5 is at the lock position) is not limited to this. For example, a configuration corresponding to the sliding portion 55 may be provided on the lid main body 3, and a configuration corresponding to the sliding portion 36 may be provided on the operation member 5.
