As shown in FIG. 2, the cover cap of this embodiment is manufactured by integral molding with the cover body B fully open.
In the present embodiment, by providing the biting window 32 on the tamper-preventing plate 31 of the cover body B, the retaining feathers 33 suspended from the tamper-preventing plate 31 can be integrally formed.

Next, when the cover body B is closed and the cover cap is set as shown in FIG. 3 from the opened state shown in FIG. 2, the handle C of the cover body B is held and rotated around the hinge C. As shown in FIG. 4, the lower surface of the claw part 34 provided at the inner lower end of the retaining feather 33 of the tamper-preventing member E abuts on the retaining convex part 16 of the mortar plug 12 of the cap body A, While slightly deforming the portion 34 upward, it gets over the latching convex portion 16.
In this case, the breaking strength of the breaking bridge 30 is set to be greater than the resistance to climb over the retaining blade 33 so that the falsification preventing plate 31 of the falsification preventing member E is not separated from the cover body B.

Further, when the cover body B is closed, the upper end surface of the side peripheral wall 20 of the cover body B and the upper surface of the tamper-preventing plate 31 (that is, the entire top surface of the cover body B) are pressed so that the breaking bridge 30 does not break. The cover body B can also be closed.
In this case, the breaking strength of the breaking bridge 30 can be set to be smaller than the resistance over the hooking feather 33.

Finally, as shown in FIG. 3 (b), the claw part 34 of the hooking feather 33 is hooked on the lower surface of the hooking convex part 16 of the mug plug 12, and the handle part 24 of the cover body B is attached to the outer cylinder 9. Further, the cover engaging portion 6 of the cap main body A is engaged with the base wall engaging portion 25 of the cover body B and is closed in an unopened state.
Since the cover cap with a mortar plug of this embodiment protects the mortar plug 12 by closing the cover body B after molding, the mortar plug 12 may be broken even when it is packed in a package. Can be prevented.

Next, as shown in FIG. 1, the cover cap with the cover body B closed is plugged into the mouth portion 1 of the container D filled with the content liquid and attached.
In the plugging process, the opening 1 of the container D is applied to the annular groove formed between the inner cylinder 8 and the outer cylinder 9 of the mounting portion 3, and the connection step formed on the side peripheral wall 20 of the cover body B A pressing force is applied from the upper surface of 22, the engaging projection 10 of the outer cylinder 9 is fitted over the fitting protrusion 2 of the mouth 1, and the mouth 1 of the container D is connected to the outer periphery of the inner cylinder 8 The cylinder 9 is mounted by being sandwiched between the inner periphery of the cylinder 9 and the base wall 7.
In the present embodiment, an annular groove formed between the inner cylinder 8 and the outer cylinder 9 is fitted into the mouth portion 1 and the cover cap is attached to the container D. However, it is not limited and may be mounted by other means such as screw connection.

In the container equipped with the cover cap with a mortar plug of this embodiment, the cover body B protects the side surface of the mortar plug 12 by the side peripheral wall 20, so that the mortar plug 12 is bent by receiving external force during distribution. Or breaking.
Moreover, the connection step part 22 formed in the side peripheral wall 20 of the cover body B has the convenience as a press part which applies a pressing force at a plugging process.

When using the content liquid in the container D, when opening the cover cap for the first time, a finger is placed on the lower surface of the handle portion 24 of the cover body B from the cutout recess 9a of the outer cylinder 9 of the cap body A shown in FIG. The cover body B is lifted, the engagement between the cover engaging portion 6 of the cap body A and the base wall engaging portion 25 of the cover body B is released, and the cover body B is rotated about the hinge C.
Then, the falsification preventing plate 31 of the falsification preventing member E tries to be lifted together with the cover body B, but the claw portions 34 of the retaining wings 33 of the falsification preventing member E are formed on the retaining projections 16 of the mug plug 12. Since the breaking strength of the breaking bridge 30 is set smaller than the pulling resistance of the claw portion 34 of the hanging feather 33, the breaking bridge 30 breaks in order from the direction opposite to the hinge C, Finally, the breaking bridge 30 on the hinge C side is also broken, and when the falsification preventing plate 31 of the falsification preventing member E is completely separated from the cover body B, as shown in FIG. It will be in the state which moved to the upper surface.
Of course, the breaking strength of the breaking bridge 30 is set to be smaller than the breaking strength of the thin portion 11 of the mortar plug 12.

  In the unopened state of the cover cap of the present embodiment, the hooks 33 of the falsification preventing plate 31 of the cover body B are hooked on the hooking projections 16 of the mortar plug 12, so that from the unopened state, When the cover body B is forcibly opened and closed, the break bridge 30 that connects the inner peripheral upper end of the small diameter portion 23 of the side peripheral wall 20 of the cover body B and the tamper-prevention plate 31 is broken, and as shown in FIG. Even if B is closed again, since the falsification preventing member E has fallen from the cover body B, it can be easily recognized that it has been opened and closed illegally.

Next, from the state shown in FIG. 5, by twisting or pushing down the knob portion 15 of the mortar plug 12 formed on the cap body A together with the tamper-proof member E, the thin-walled portion 11 is broken, and the mortar plug 12 is broken. Is removed from the nozzle 5, the nozzle hole 13 is opened at the tip 5 a of the nozzle 5, and the nozzle 5 is opened.
By opening the nozzle 5 of the cap body A, the content liquid in the container D can be easily poured out from the nozzle 5 simply by tilting the container D.

In the present embodiment, the cover body B becomes only the side peripheral wall 20 after the tamper-proof plate 31 is separated, and the top surface is opened. Therefore, as shown in FIG. Even when closed, the content liquid can be poured out from the nozzle 5 in any direction through the inner peripheral surface of the side peripheral wall 20 of the cover body B.
Further, after the content liquid is poured out with the cover body B closed, even if the liquid leaks from the vicinity of the tip 5a of the nozzle 5, the inner peripheral surface of the side peripheral wall 20 of the cover body B and the upper wall 4 of the cap body A It can be prevented from flowing out of the cover cap.
Of course, it is also possible to pour directly from the nozzle 5 with the cover body B open.

Since the cover cap of the present embodiment is basically for a container where the content liquid is used up once, after the content liquid is poured out from the container D, it can be discarded as it is.
In addition, the container D is not limited to the one that tilts and discharges the content liquid from the nozzle 5, but may be one that squeezes the container D and discharges the content liquid from the nozzle 5.

  The cover cap with a mortar plug of the present invention can protect the mortar plug by closing the cover body. Even if it is not, it is possible to prevent the mortar from being inadvertently broken, and it is particularly suitable as a cover cap with a mortar plug for a container filled with a chlorine-based content liquid that is used once.
