Next, the effect of the cap of this invention is demonstrated.
In the production process of the container, first, a cap is produced, and the lid B is closed on the cap body A.

  When the cap is first closed, the inclined surface 27b of the locking projection 27 of the sealing rib 22 of the lid B comes into contact with the inner surface of the sealing portion 13 of the sealing member 10 of the outer peripheral wall portion 4 of the cap body A, The sealing rib 22 is inserted into the insertion port b of the outer peripheral wall 4 of the cap body A while slightly deforming the sealing member 10.

Finally, the locking protrusion 27 of the sealing rib 22 is inserted into the locking notch 16 of the sealing member 10 so that the deformation of the sealing member 10 is released, and the inner side surface and both sides of the sealing portion 13 of the sealing member 10 are released. The outer side surface of the sealing rib 22 and the inclined side surfaces 22c of both side surfaces abut on the inner surface of the inclined connecting portion 14, and the sealing rib 22 is fitted into the insertion port b.
Further, the upper outer periphery of the lid engaging portion 2 of the cap body A and the inner periphery of the engaging portion 24 of the lid B are engaged, and the lid is closed as an unopened state.

  Before the cap is attached to the container body, or after the cap is attached to the container body, the cap engaging portion 2 of the cap body A and the engaging portion 24 of the lid body B are engaged in the unopened state of the cap. In addition, the locking protrusion 27 of the sealing rib 22 is inserted into the locking notch 16 of the sealing member 10, and the upper surface 27 a of the locking protrusion 27 of the sealing rib 22 is the locking notch 16 of the sealing member 10. By engaging with the locking lower surface 16a, the closed state can be maintained more firmly.

  Even if the lid is forcibly opened from the unopened state, the upper surface 27a of the locking projection 27 of the sealing rib 22 is engaged with the locking lower surface 16a of the locking notch 16 of the sealing member 10, and the sealing rib Since the outer surface of 22 and the inner surface of the sealing member 10 are in contact with each other and become a resistance, the lid cannot be easily opened.

  In the unopened state, the sealing protrusion 17 of the sealing part 13 of the sealing member 10 of the cap body A covers the finger-engaging recess 25 of the outer peripheral wall 21 of the lid B. The cover cannot be hung on the recess 25 and can be prevented from opening.

In the production process of a container, before attaching a cap to a container main body, many caps are put in a single box or the like in an unopened state for transportation.
At that time, in the cap of the present invention, since the sealing protrusions 17 of the sealing member 10 of the cap body A are formed in an arc shape, the sealing protrusions 17 of a large number of caps inserted as shown in FIG. In addition, it is possible to prevent the sealing member 10 from being removed from the outer peripheral wall 9 by invading, biting and pulling inside each other.

  Further, the portion of the inclined side surface 22c of the sealing rib 22 of the lid B is inserted into the insertion port b of the sealing member 10 of the cap body A to close the insertion port b, and the sealing member 10 and the sealing rib 22 in an unopened state. And the flat side surface 22b of the sealing rib 22 and a portion in the vicinity thereof protrude above the insertion port b of the cap body A.

By making the side surface of the sealing rib 22 into a flat flat side surface 22b, the sealing protrusions 17 and other portions of other caps inserted therein are more sealed ribs than those in which the end of the side surface of the sealing rib 22 is curved. Since the portion that abuts the side surface of the cap 22 becomes wider, the flat side surface 22b of the sealing rib 22 protruding upward from the insertion port b of the cap body A and a portion in the vicinity thereof are located on the inside of the sealing projection 17 and another cap. It is possible to prevent the sealing protrusion 17 and other parts from entering.
Moreover, compared with what the edge part of the side surface of the sealing rib 22 curved, the clearance gap between the part which protrudes upwards from the insertion port b of the cap main body A of the sealing member 10 and the sealing rib 22 can be made small. As a result, it is possible to prevent the sealing protrusions 17 and other parts of other caps inserted from the lateral gap from entering the inside of the sealing member 10, biting and pulling. .

  Next, the closed cap is attached to the mouth tube portion of the container body filled with the contents by a stopper or the like to obtain a container with the cap closed.

  In order to use the contents in the container of the present invention, when the cap is first opened, first, on the left or right side from the central portion of the upper portion of the sealing projection 17 of the sealing member 10 of the cap body A. Hang your finger and pull it forward.

  By pulling the left or right side of the upper part of the sealing projection 17 of the sealing member 10, the sealing part 13 and the inclined connecting part 14 of the sealing member 10 on that side are pulled, and the weakening part 15 on that side is cut from above. Finally, as shown in FIG. 7, the inclined connecting portion 14 on that side is completely separated from the outer peripheral wall 9.

  The sealing member 10 and the outer peripheral wall 9 of the cap main body A of the present invention are such that the inclined connecting portion 14 and the weakening portion 15 on both sides are inclined with respect to the outer peripheral wall 9 so that the upper portion is inclined toward the lower portion and toward the central portion. Since it is formed, it becomes a resistance to tear the weakened portion 15 downward from above, compared to the case without an inclination, so that it does not tear unless a certain amount of force is applied.

  Further, the sealing member 10 is connected to the outer peripheral wall 9 so as to be inclined in a reverse C shape when viewed from the opposite side of the hinge C via the weakened portions 15 on both sides. Even if the central part of the sealing member 10 is pulled, it becomes resistance, and unless it is pulled too strongly, the weakened part 15 cannot be cut and the sealing member 10 cannot be removed from the outer peripheral wall 9.

  When one of the left and right inclined connecting portions 14 is cut, the sealing member 10 is further pulled, the opposite weakened portion 15 is cut, the inclined connecting portion 14 is cut off from the outer peripheral wall 9, and the sealing member 10 is removed from the cap body A. To do.

  After either of the left and right inclined connecting portions 14 is cut off or after the sealing member 10 is removed from the cap body A, the engagement between the sealing rib 22 of the lid B and the sealing member 10 is released, and the cap body The closed state is maintained by the engagement of the lid engaging portion 2 of A and the engaging portion 24 of the lid B.

Next, a finger is put on the finger-hanging recess 25 of the outer peripheral wall 21 of the lid B, the lid B is pushed up, and the lid is opened.
At that time, the closed state is maintained only by the engagement between the lid engaging portion 2 of the cap body A and the engaging portion 24 of the lid B, and the lid can be easily opened.

  When the cover B is pushed up, a portion of the finger that is positioned below the outer peripheral wall 21 of the finger-hanging recess 25 abuts against the outer surface of the sealing rib 22, so that the finger is outside the dispensing cylinder 1 of the cap body A. Can be prevented from touching, and the lid can be opened cleanly without soiling the finger or the dispensing tube 1.

  Further, since the finger that contacts the sealing rib 22 contacts the curved surface 22a that continues from the lower outer surface of the finger-hanging recess 25, the touch of the finger when pushing up is softened, preventing the finger from being damaged or feeling uncomfortable. can do.

  After opening the lid, the removal portion 7 is unplugged from the partition wall 5 of the cap body A, the spout is opened, and the container is tilted to pour out the contents via the pour cylinder 1.

  When the cap of the present invention is opened from the unopened state, the lid is not opened unless the weakened portion 15 is cut from the outer peripheral wall portion 4 of the cap body A. Therefore, the cap is opened depending on the state of the sealing member 10 and the weakened portion 15. This can be easily recognized, and it can be easily confirmed from the appearance that it has been tampered with.

  By closing the lid B on the cap body A again, the lower outer periphery of the sealing cylinder 23 of the lid B is engaged with the upper inner periphery of the dispensing cylinder 1 of the cap main body A, thereby sealing the inside of the cap A. Even after opening the partition wall 5 of the cap body A, the lid B can be repeatedly opened and closed to use the content liquid.

The cap of the present invention can be separated from the container body and discarded after the entire contents in the container are used.
At that time, when the cap is opened and the lid B is pulled upward, the outer peripheral wall 9 of the cap body A is pulled via the hinge C, and the weakened piece 12 is cut.
When the weakening piece 12 is cut, the outer peripheral wall 9 is deformed away from the outer cylinder 8 of the outer peripheral wall portion 4 while pulling the connecting piece 11 on the opposite side of the hinge C, and the outer peripheral wall portion 4 is connected via the connecting piece 11. The lower part of the outer cylinder 8 opposite to the hinge C is pulled.
When a part of the lower portion of the outer cylinder 8 is pulled up, the outer cylinder 8 is deformed, the cap body A and the mouth tube portion of the container body are disengaged, and the cap and the container body are separated and discarded. it can.

In the above embodiment, the outer peripheral wall 4 of the cap main body A is connected to the outer cylinder 8 with the inner peripheral upper end connected to the outer edge of the lid engaging portion 2 and the hinge C to the outer peripheral upper end as an unauthorized cap. An outer peripheral wall 9 connected to the outer periphery of the outer cylinder 8 at a distance a and a sealing member 10 are provided. After all the contents in the container are used, the lid B is pulled and the hinge C is interposed. Pulling the outer peripheral wall 9 to easily separate and discard the container main body and the cap, but if you do not consider separating and discarding the container main body and the cap separately, the outer peripheral wall portion of the cap main body is The inner peripheral upper end may be continuously provided on the outer edge of the ring-shaped lid engaging portion, and the hinge may be provided on the outer periphery, and the sealing member may be provided on the opposite side of the hinge.
