Further, the horizontal length of the display opening 61 is formed to be at least approximately the same as the horizontal length of the display portion 34 of the flange portion 31 of the locking plate portion D, and the display opening 61 is displayed at the same position. The portion 34 is made visible.

Next, the usage mode and effects of this embodiment will be explained.
First, in manufacturing the pouring cap of this example, the cap body B has through holes 38 of the same shape drilled in the flange portion 31 under the undercut portions 37 of the respective protrusions 35. Therefore, it is possible to change from a mold splitting mechanism to a vertical punching mechanism in which a lower mold is provided in the shape of the through hole 38 and an upper mold is provided to mold the protrusion 35, and the undercut portion 37 can be forcibly removed. A clear shape can be formed without any distortion, and manufacturing is easy.

After molding the spouting cap, to attach the spouting cap to the container body A, push the lid C from the top of the cap body B, set the cap body B and the lid C, and then insert the spout cap into the opening of the container body A. The annular groove of the attachment part 4 of the cap body B is applied to the part 1 and the cap is plugged.

When setting the lid C from the upper part of the cap body B, place the cutting tube part 43 of the screw cap C1 of the lid C on the pouring tube 10 of the cap body B, and then press the second tooth part 47 of the cutting tube part 43. and the first tooth portion 18 of the cylindrical wall 16 of the transition plug body 15, and the locking plate portion D of the cap body B is inserted under each through hole 56 of the sealing flange portion 55 of the sealing portion C2. Each protrusion 35 of the flange portion 31 is arranged.

When the lid C is pushed into the cap body B from this state, the second threaded part 50 of the screw cap C1 slides over the first threaded part 24, and the threaded cylinder part 44 of the screw cap C1 is pushed into the cap body B. It comes to fit into the threaded wall portion 8 of B.
As the pushing progresses further, the second engagement protrusion 46 of the cutting tube part 43 passes over the first engagement protrusion 19 of the transition plug body 15 and fits into the outer circumferential surface of the enlarged diameter part 22, and the screw The wedge-shaped recess 51 at the bottom of the cylindrical portion 44 fits into the stopper 28 on the upper wall 7 of the cap body B, and the lid C is connected to the cap body B by the threaded cylindrical portion 44 of the screw cap C1 and the screw wall of the cap body B. It is set in a state where it is screwed together with part 8.

At the same time, the sealing portion C2 has the protrusion 35 of the flange portion 31 of the locking plate portion D of the cap body B inserted into the through hole 56 of the sealing flange portion 55, and finally the sealing portion C2 is closed as shown in FIGS. 1 and 6(a). As shown in FIG. 3, the sealing flange portion 55 covers the upper surface of the flange portion 31, and the undercut portion 37 at the upper portion of the projection portion 35 is set to protrude above the through hole 56.

Next, in order to use the container equipped with the pouring cap of this embodiment, grasp the screw cap C1 of the lid body C, rotate it in the lid opening direction with respect to the cap body B, and open the screw cap C1. By unscrewing the second threaded part 50 of the threaded cylinder part 44 and the first threaded part 24 of the threaded wall part 8 of the cap body B, the threaded cap C1 is opened while being raised.

When the lid C is rotated, along with the rotation of the second tooth portion 47 of the cutting tube portion 43, the rotational force of the lid C is applied to the transition stopper 15 via the first tooth portion 18 of the cap body B that comes into contact with it. Become a part of it.
At this time, since the second engagement protrusion 46 of the cutting tube part 43 is engaged with the first engagement protrusion 19 of the cylindrical wall 16, a force is exerted to pull the transition plug body 15 upward as it rotates. to occur.

As the rotation of the lid body C progresses, the thin weakened portion 14 of the cap body B breaks due to the rotational force and lifting force applied to the transition stopper body 15, opening the spout and separating it from the spout cylinder 10. The transition plug body 15 is pulled up by the cutting tube portion 43 that engages with the cylindrical wall 16 and rises together with the screw cap C1 of the lid body C.

Further, as the lid C rotates, the sealing portion C2 connected to the screw cap C1 by the weakened connection piece 42 also rotates.
Even if the sealing part C2 rotates together with the screw cap C1, the locking plate part D of the cap body B does not rotate and the protrusion 35 does not move. The inner surface of the inner and outer circular arc portions 57a of the guide opening 57 of the sealing flange portion 55 of the sealing portion C2 abuts and is guided by the parallel surface portion 35c of the fitting recess 36, which is separated by a distance α on both the inner and outer sides.
At the same time, the lower surfaces of the undercut portions 37 on the inner and outer sides of the projection portion 35 are guided so as not to come off by contacting the upper surface of the sealing flange portion 55 near the circular arc portion 57a, and the sealing portion C2 is guided so as not to come off. Rotate along the top surface.

Finally, as shown in FIG. 6(c), the protrusion 35 passes over the locking protrusion 59 in the guide opening 57 and comes into contact with the end 57b, and the lower surfaces of the undercuts 37 on both sides The protrusion 35 is locked in the locking opening 60 of the guide opening 57 so that it comes into contact with the upper surface of the sealing flange 55 near the circular arc portion 57a and does not come off upward.
Further, when viewed from above, the display body 58 of the sealing part C2 is close to the projection part 35, and the display part 34 of the locking plate part D is located below the display opening 61 of the guide opening 57 of the sealing part C2. The display section 34 becomes visible through the display opening 61.

When the protrusion 35 of the flange portion 31 comes into contact with the end 57b of the guide opening 57 and is locked in the locking opening 60, the sealing flange portion 55 of the sealing portion C2 engages with the locking plate portion D. It fits into the flange portion 31 and rotation is stopped.
Furthermore, as the screw cap C1 continues to rotate, the sealing flange portion 55 of the sealing portion C2 is stopped from rotating, so the weakened connecting piece 42 that connects with the sealing flange portion 55 breaks, and the sealing portion C2 is The screw cap C1 continues to rise.

As described above, when the lid C is opened, the screw cap C1 rises with respect to the cap body B, while the sealing part C2 fits into the locking plate part D of the cap body B. However, since the rotation is stopped, the weakened connection piece 42 is broken, and the sealing portion C2 remains on the locking plate portion D.
Further, when the screw cap C1 is rotated, the screw tube portion 44 of the screw cap C1 and the screw wall portion 8 of the cap body B are unscrewed, and the screw cap C1 is opened.
The contents in the container body A can be poured out from the opening of the pouring cylinder 10 of the cap body B from which the transfer stopper 15 has been removed together with the screw cap C1.

Even if the screw cap C1 is closed on the cap body B again, the sealing part C2 does not fit into the projection of the locking plate part D within the locking opening 60 of the guide opening 57, as shown in FIG. 6(c). Since the parts 35 are locked in the fitted state, from the appearance, it is possible to see that in addition to the broken state of the weakened connection piece 42 that connects the screw cap C1 and the sealing part C2, the indicator 58 of the sealing part C2 The opening of the lid C can be confirmed at a glance due to the proximity of the projection part 35 and the display part 34 which can be viewed through the display opening 61 of the sealing part C2.

After using the container, by screwing the screw cap C1 onto the cap body B, the outer periphery of the cutting tube portion 43 of the screw cap C1 comes into contact with the inner periphery of the pouring tube 10, and the inside of the container can be sealed again. .
When the screwing is completed, the sound emitting member 45 comes into contact with the sound emitting protrusion 11 and vibrates, emitting a sound, so that it is possible to know that the dispensing cap has been closed, and the screw of the screw cap C1 The wedge-shaped recess 51 at the bottom of the cylindrical portion 44 fits into the stopper 28 on the upper wall 7 of the cap body B to stop the screwing, so it is possible to prevent the lid from being closed too much and becoming unable to open.

After the first lid is opened, the sealing flange portion 55 of the sealing portion C2 covers and fits over the upper surface of the flange portion 31 of the locking plate portion D of the cap body B, so that the upper surface of the locking plate portion D is not exposed. First, when the container is in use, the weakening groove 29 of the cap body B is cut by contacting the flange portion 31 of the locking plate portion D and breaking the breakage portion 33, thereby preventing the cap body B from being removed from the container body A. are doing.

When discarding the pouring cap of this embodiment after using the container, insert your finger between the sealing flange portion 55 of the sealing portion C2 and the flange portion 31 of the locking plate portion D shown in FIG. Then, by pinching the right end of the notch 32 of the flange portion 31 and breaking the broken portion 33 downward, and pulling further, the outside of the cap body B is removed via the connecting portion 30 connected to the opposite side. When the lower end of the cylinder 5 is pulled upward, the weakened groove 29 portion of the outer cylinder 5 is broken from below.

By breaking and pulling the weakened groove 29 portion of the outer cylinder 5, the engagement between the reduced diameter locking portion 27 near the weakened groove 29 of the cap body B and the locking protrusion 2 of the container body A is released. By easily separating the cap body B from the container body A, the cap body B can be disposed of separately.
In this embodiment, the flange portion 31 of the locking plate portion D is formed with a uniform thickness, but the flange portion 31 near the right side of the notch portion 32 when seen in FIG. It may be formed thinner than other parts to make it easier to insert a finger between the sealing part C2 and the locking plate part D during separate disposal.
Further, in this embodiment, the outer diameters of the flange portion 31 of the locking plate portion D and the sealing flange portion 55 of the sealing portion C2 are set to be the same, but the outer diameter of the flange portion 31 of the locking plate portion D is may be made larger than the outer diameter of the sealing flange portion 55 of the sealing portion C2 to make it easier to grip the flange portion 31.

In this embodiment, the locking plate portion D forms a flange portion 31 with a gap provided between the locking plate portion D and the outer periphery of the outer cylinder 5. The portion may be formed along the outer periphery of the outer cylinder 5.

The dispensing cap of the present invention reliably locks the sealing portion separated from the lid to the cap body simply by rotating the lid in the opening direction, so that the display portion of the cap body displays the sealing portion. It is visible through the opening, and you can tell at a glance that the seal has been opened based on the condition of the seal, making it suitable as a pouring cap that can be used for containers such as food and beverages and seasonings that need to be kept sealed before use.
