  Next, a method of using or operating the pouring cap 1 with a lid according to an embodiment of the present invention having such a configuration will be described.

  As shown in FIG. 1, when the lid 3 is closed, the inner peripheral surface of the operation portion 20 of the opening operation member 4 is fixed to the locking ridge 22 provided on the outer peripheral surface of the small-diameter cylindrical portion 5 b of the dispensing cap body 2. Engagement ridges 23 provided on the engagement are engaged, and the lid 3 is held in a closed state. At this time, the operation protrusion 21 of the opening operation member 4 is positioned below the flange 12 of the lid body 3, and the lid body 3 is not opened unless the opening operation member 4 is rotated. In this way, when not in use, the lid 3 is held in the closed state by the opening operation member 4, so that the lid 3 is prevented from being inadvertently opened due to overturning of the container and the like, and the contents from the container Leakage of objects can be prevented.

  From this state, the operation protrusion 21 of the opening operation member 4 is pushed with a finger or the like, and the operation portion 20 is rotated in the left-right direction, that is, rotated with respect to the lid 3, thereby engaging the engagement protrusion 22. The engagement ridges 23 can be released from the engagement ridges 22 by shifting the position 23 in the circumferential direction. When the engagement of the engaging ridges 23 with respect to the locking ridges 22 is released, the lid 3 can be opened by pulling up the collar portion 12. Therefore, the lid 3 can be easily opened by rotating the operation portion 20 of the opening operation member 4 to either the left or right.

  When the assembling unit 15 rotates with respect to the lid body 3 in accordance with the rotation operation of the operation unit 20, the spring body 24 held at the distal end side between the pair of holding pieces 25 is elastically deformed and bent in the rotation direction, An elastic force is applied to the operation unit 20 at an initial position, that is, a position where the engaging ridges 22 and the engaging ridges 23 can be engaged. Therefore, when the operation of the operation protrusion 21 is released, the operation unit 20 automatically returns to the initial position by the elastic force of the spring body 24. Thus, after the turning operation, the operation unit 20 automatically returns to the initial position. Therefore, when the opened lid 3 is next closed, the operation unit 20 is engaged without performing the return operation. The protrusions 23 can be engaged with the locking protrusions 22 to hold the lid 3 in a closed state. When the lid 3 is closed, the locking ridges 22 and the engaging ridges 23 are each formed in a triangular cross section, so that the locking ridges 22 and the engaging ridges 23 are inclined surfaces. By engaging, the operating portion 20 is elastically deformed in the diameter increasing direction, and the engaging ridges 23 can get over the locking ridges 22.

  Here, when opening the lid 3, the operation unit 20 can be rotated with respect to the lid 3 in either the left-right direction, that is, the one side or the other side in the circumferential direction. Regardless of whether the operation unit 20 is rotated to one side or the other side in the circumferential direction, the engagement protrusion 23 with respect to the engagement protrusion 22 is shifted in the circumferential direction to engage with the engagement protrusion 22. The engagement of the joint ridges 23 can be released and the lid 3 can be opened. In addition, even if the operation unit 20 is rotated to one side of the circumferential direction, the spring body 24 is elastically deformed and bent in the rotation direction corresponding to the direction of the rotation operation. The operation unit 20 can be automatically returned to the initial position by applying an elastic force toward the initial position to the unit 20.

  Thus, in the present invention, the rod-shaped spring body 24 provided in the assembly portion 15 is disposed between the pair of holding pieces 25 provided on the inner surface of the top wall 10 of the lid 3, and the operation portion 20 is rotated. Since the spring body 24 is elastically deformed in the rotation direction when the operation is performed, and the operation unit 20 is returned to the initial position by the elastic force of the spring body 24, the opening operation member 4 is arranged on one side in the circumferential direction. The lid 3 can be opened even if it is rotated in any direction on the other side. Thereby, the operativity of the opening operation member 4 of this extraction cap 1 with a lid | cover can be improved.

  Further, in the present invention, the pair of holding pieces 25 that hold the spring body 24 are formed in the shape of parallel walls facing each other with the spring body 24 interposed therebetween. An elastic force for returning to the operation unit 20 can be applied to the operation unit 20.

  Further, by forming the end portion of the holding piece 25 facing the spring body 24 in a U shape, the spring body 24 can be easily elastically deformed along the C shape portion of the holding piece 25. Therefore, a sufficient elastic force can be generated in the spring body 24 with a simple and small configuration.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above-described embodiment, the ends of the pair of holding pieces 25 on the side of the spring body 24 are formed in a C shape, but the present invention is not limited to this, and the spring body 24 is rotated in the rotational direction. As long as the shape can be held and elastically deformed in the rotational direction, for example, as shown in FIG. Also good.

  In the above embodiment, two locking ridges 22 and two engaging ridges 23 are provided. However, the present invention is not limited to this, and the engaging ridges 23 are provided on the locking ridges 22. The cover 3 can be kept closed by being engaged, and when the operating portion 20 is rotated, the engaging ridge 23 is displaced in the circumferential direction with respect to the locking ridge 22 and the engagement is released. If possible, the number and size of the locking ridges 22 and the engaging ridges 23 can be set arbitrarily.
