  A substantially cylindrical extraction nozzle main body 23 is integrally formed on the container outer side portion of the base flange portion 21 of the extraction nozzle 20 so as to protrude to the center portion, and two flange portions 24 and 25 are provided in the middle portion. It is.

  Of these intermediate flange portions 24 and 25, the portion of the dispensing nozzle body 23 protruding upward from the upper flange portion 25 is used as a catheter or tube connection portion 26 after opening, and the tip portion is narrowed in a conical shape. The connecting member 26 is integrally formed with an opening member 28 for cutting through a cutting part 27 for cutting.

  The opening member 28 protrudes on both sides of the disk portion 29 on the upper portion of the connection portion 26 of the dispensing nozzle body 23 to form an operation portion 30 for cutting operation, and the operation portion 30 rotates about the central axis. The tip of the dispensing nozzle 20 can be opened by being separated from the cut-out portion 27 by, for example, pushing up from the lower side, or by combining these rotation and push-up.

  On the other hand, as shown in FIGS. 1 and 3, the cover cap 40 that covers the pouring nozzle 20 includes a substantially cylindrical cover cap body 41 that is applied to the flange portion 25 above the pouring nozzle body 23. In addition, two opposed outer cylinder portions 42 having a U-shaped cross section and disposed so as to surround the outside of the operation portion 30 of the opening member 28 and two conical portions 43 adjacent thereto are provided. Thus, the outer side of the pouring nozzle 20 can be covered.

  In the fluid container pouring device 10 constituted by the pouring nozzle 20 and the cover cap 40 covering the pouring nozzle 20, the opening member 28 provided via the cutout portion 27 of the pouring nozzle 20 is replaced with the cover cap 40. In order to cut off and open by turning, a detaching cam mechanism 45 is provided.

  The separation cam mechanism 45 is provided with a separation cam 46 having a central portion high and inclined on both sides inside the conical portion 43 of the cover cap 40, and a lower surface of the operation portion 30 of the opening member 28 as a cam follower. By rotating the cap 40 about its central axis, the operation unit 30 can be pushed up, whereby the opening member 28 can be separated from the cutout unit 27.

  During the separation operation, the lower surface of the operation portion 30 of the opening member 28 is pressed by the separation cam 46, and the upper surface is pressed by the bridge-shaped pressing member 44, and the cut opening member 28 is separated from the cutting cam 46 and the pressing member 44. The cut piece holding means 47 is configured such that the cut piece holding means 47 holds the cut piece (opening member 28) in the cover cap 40 and can be removed together with the cover cap 40. .

  When such an opening member 28 is cut off by being cut off by the separation cam 46 when the cover cap 40 is rotated, if the relative rotation occurs between the dispensing nozzle 20 and the cover cap 40, an opening may be generated. Therefore, a rotation preventing means 50 for preventing this rotation is provided.

  The rotation preventing means 50 between the pouring nozzle 20 and the cover cap 40 is a nozzle plane that is cut out in two planes facing each other across the central axis of the disc-shaped flange portion 25 above the pouring nozzle 20. While forming the portion 51, two cap flat portions 52 are formed so as to protrude inside the corresponding cover cap body 41 of the cover cap 40. Before the opening operation, the nozzle flat surface portion 51 and the cap flat surface portion 52 come into surface contact so that the cover cap 40 cannot be easily rotated. It is designed so that it can rotate over the nozzle flat surface 51 by elastic deformation of 40.

  By providing such a nozzle flat surface portion 51 and a cap flat surface portion 52, it can be used for alignment when assembling the dispensing nozzle 20 and the cover cap 40, and the conical portion 43 and the pressing member 44 of the cover cap 40 can be used. In cooperation with the shape arrangement, the assembly work can be facilitated as a mark.

  The nozzle flat part 51 and the cap flat part 52 provided as the rotation preventing means 50 are formed at two opposite positions as shown in FIGS. 2 and 3, as shown in FIG. In addition, there may be three places at equal intervals around the circumference, or four places as shown in FIG.

  Furthermore, the cap flat surface portion 52 of the cover cap 40 functioning as the rotation preventing means 50 is not limited to one constituted by a continuous straight line. For example, as shown in FIG. The flat portion 52 may be provided, and the flat portion in this case may be further increased in addition to the case where two portions are provided at equal intervals around the circumference.

  In such a fluid container pouring device 10, it is necessary to prevent relative rotation of the cover cap 40 and to prevent the cover cap 40 from coming off in the axial direction until the opening operation is completed. It is provided.

  The disengagement prevention means 60 of the cover cap 40 uses the flange portion 25 above the pouring nozzle 20, and hooks a locking protrusion 61 that protrudes to the inside of the lower end of the cover cap body 41 of the cover cap 40 on its lower surface. While preventing the disengagement by locking, the outer periphery of the rotation preventing means 50 formed in the flange portion 25 is cut away by the nozzle flat portion 51 so that the locking protrusion 61 is not caught. Thus, the lock can be released.

  When the nozzle flat surface portion 51 is not provided, the cover cap body 41 can be elastically deformed and lifted to release the lock.

  On the other hand, in this disengagement prevention means 60, when the cover cap 40 is put on the dispensing nozzle 20, the locking projection 61 is positioned other than the nozzle flat surface portion 51 of the upper flange portion 25 and is locked. In the state where the cover cap 40 is rotated and the opening member 28 is separated by the separation cam 46 and the separation is completed, the locking projection 61 can be positioned on the nozzle flat surface portion 51 to be opened. It is like that.

  As described above, the nozzle flat portion 51 of the rotation preventing means 50 is used for preventing the cover cap 40 from rotating, and at the same time, used for releasing the locking projection 61 of the removal preventing means 60 of the cover cap 40. This also serves to simplify the structure and facilitate manufacture.

  Furthermore, in this fluid container pouring device 10, the cover cap 40 is turned off and the opening member 28 of the pouring nozzle 20 is cut off to complete the opening. In order to clearly know this and to be able to remove the cover cap 40, a cover cap removal cam mechanism 70 is provided. To move to.

  In this cover cap removal cam mechanism 70, a pair of removal cams 71 projecting downward on the inner periphery of the lower portion of the cover cap 40 is formed across the central axis, and a cam follower 72 corresponding to these removal cams 71 is provided for the dispensing nozzle 20. The upper flange portion 25 is formed so as to protrude from two locations on the upper surface.

  By rotating the cover cap 40 with the detaching cam 71 and the cam follower 72, the cover cap 40 can be lifted up so as to be pushed up in the axial direction.

  Accordingly, it can be seen that the cover cap 40 may be removed from the dispensing nozzle 20 and that the locking of the cover cap 40 detachment preventing means 60 is released.

  When only the locking projection 61 is provided as the means 60 for preventing the cover cap 40 from being removed and the nozzle flat part 51 is not provided, the nozzle flat part 51 is not opened depending on the rotation position. It is possible to release the locking by elastically deforming the locking projection 61 by lifting up with the 40 removal cams 71.

  Further, the separation cam 46 of the separation cam mechanism 45 is positioned 90 degrees away from the operation portion 30 of the opening member 28 in the rotational direction, and the removal cam 71 of the cap removal cam mechanism 70 is in a state before being pushed up. It faces the cam follower 72 of the flange portion 25 of the dispensing nozzle 20 or is in contact therewith.

Next, when taking out the contents (fluid) in the fluid container, a finger is put on the finger-hanging rib 41a of the cover cap 40, and the pouring nozzle is rotated so that the cover cap 40 is rotated around its central axis. Rotate along the outside of 20.
At this time, since the nozzle flat portion 51 of the dispensing nozzle 20 constituting the rotation preventing mechanism 50 and the cap flat portion 52 of the cover cap 40 are in surface contact with each other, the cover cap 40 is elastically deformed to cause the nozzle flat surface. The rotation preventing mechanism 50 is opened so as to get over the portion 51.

  By the rotation of the cover cap 40, the detaching cam 46 of the detaching cam mechanism 45 first enters the lower side of the operation unit 30 on both sides of the opening member 28, and thereafter starts contact with the lower surface of the operation unit 30. When rotated, as shown in FIG. 1 (b), the operation unit 30 is pushed up on both sides and cut out from the cutout unit 27.

  The cut opening member 28 is sandwiched between the pressing member 44 and the detaching cam 46 of the cover cap main body 41 constituting the cut piece holding means 47 and is securely held in the cover cap 40.

  Further, after the separation cam 46 of the separation cam mechanism 45 enters the lower side of the operation portion 30 on both sides of the opening member 28 by the rotation of the cover cap 40, the removal cam 71 and the cam follower 72 of the cap removal cam mechanism 70 When the contact cap is started and the cover cap 40 is pushed up and the opening member 28 is cut off, the cover cap 40 is lifted up from the flange portion 25 of the dispensing nozzle 20. At the same time, the locking projection 61 of the mechanism 60 for preventing the cap cap 40 from coming off is located on the nozzle flat portion 51 due to the elastic deformation caused by the lift-up of the cover cap 40 and the locking is released.

  Thus, in a state where the cover cap 40 is lifted up from the flange portion 25 of the dispensing nozzle 20, it is easily known that the cutting of the opening member 28 is completed and the detachment prevention mechanism 60 of the cover cap 40 is opened. It can be seen that the cover cap 40 can be removed from the dispensing nozzle 20.
