Next, the effect of the hinge cap of this invention is demonstrated.
In the present invention, the engagement portion 22 of the outer peripheral wall 21 of the upper lid B and the lid engagement portion 9 of the engagement cylinder portion 2 of the cap body A are engaged and closed, and then the mouth of the container filled with the content liquid. The hinge cap closed on the tube portion is plugged from above.

  At the time of stoppering, the mouth tube portion of the container is sandwiched between the outer periphery of the inner tube 7 of the engagement tube portion 2 of the cap body A and the inner periphery of the outer tube 8, and the engagement protrusion 11 of the cap body A is The cap body A is engaged with the outer periphery of the cap body A to prevent the cap body A from falling off and is attached to the mouth tube section of the container.

  When removing the hinge cap from the container and disposing of it after using all of the contents liquid, first open the top lid B, then generally hold the top lid B with the right hand if the user is right-handed And pull it in the clockwise direction along with the lower rear.

  When the upper lid B is pulled in the clockwise direction, a force in the clockwise direction is applied to the hinge connecting portion 3d of the outer peripheral wall 3 of the cap body A via the hinge C as shown in FIG. While cutting the cutting | disconnection part 13, the hinge side thin wall 17 between the outer peripheral wall part 3 and the outer cylinder 8 is cut | disconnected from the window part 18a side.

  The left cutting portion 13 can easily cut the upper vertical cutting groove 13b from above by the cut 13a. Further, after the upper vertical cutting groove 13b is cut, the left cutting portion 13 is inclined downward by applying a force in the right rotation direction. The cutting groove 13c can be cut from the upper side to the lower side toward the center side of the hinge C.

The force applied to the hinge-side thin upper wall 17 by the thick portion 17a becomes a resistance due to a certain amount of force required for cutting, and the force applied to the hinge-side thin upper wall 17 is the force applied to the lower rear wall. It is possible to prevent cutting.
Further, when a force is applied in the right rotation direction, a force is applied to the end portion of the thin portion 17b on the window portion 18a side, the thin portion 17b is easily cut, and then the thick portion 17a is cut, and the hinge The side thin upper wall 17 can be easily cut.

  Further, since the hinge-side thin upper wall 17 is prevented from being cut by the force applied to the lower and rear sides, the hinge connecting portion 3d is prevented from being deformed with respect to the lower and rear sides, and the right cutting portion 14 is cut by applying a force. Can be prevented.

  After the left cut portion 13 and the hinge-side thin upper wall 17 are cut, when the upper lid B is further pulled in the clockwise direction and the hinge connecting portion 3d is pulled, as shown in FIG. While being pulled away from the outer cylinder 8, the right thin upper wall 16 is cut.

  When the left cut portion 13 and the hinge-side thin upper wall 17 are cut and then the hinge connecting portion 3d is pulled, force is also applied to the right cut portion 14, but the upper vertical cut groove 14b of the right cut portion 14 is cut. Even so, since the lower inclined cutting portion 14c is inclined to the hinge C side, it is not cut due to resistance against the force in the right rotation direction, so the right cutting portion 14 is completely against the force in the right rotation direction. It is possible to prevent cutting.

  When the right side wall 3c is separated from the outer cylinder 8 and further pulled, the right side wall 3c pulls the connecting part 12, and further pulls and deforms the opposite side of the hinge C of the outer cylinder 8, so that the outer cylinder 8 and the mouth of the container When the engagement with the outer periphery of the tube portion is released and finally pulled upward, the cap body A can be easily removed from the mouth tube portion of the container and discarded.

Next, when the user is left-handed, the upper lid B is generally gripped with the left hand and pulled in the left rotation direction together with the lower rear.
When the upper lid B is pulled in the left rotation direction, a force in the left rotation direction is applied to the hinge connecting portion 3d of the outer peripheral wall portion 3 of the cap body A via the hinge C as shown in FIG. While cutting the cutting part 14, the hinge side thin upper wall 17 between the outer peripheral wall part 3 and the outer cylinder 8 is cut | disconnected from the window part 18b side.

  The right cutting portion 14 can easily cut the upper vertical cutting groove 14b from above by the cut 14a. Further, after the upper vertical cutting groove 14b is cut, if a force is applied in the left rotation direction, the lower cutting is performed. The portion 14c can be cut from the upper side to the lower side toward the center side of the hinge C.

  The hinge-side thin upper wall 17 can prevent the hinge-side thin upper wall 17 from being cut by a force applied downward and rearward. When a force is applied in the counterclockwise direction, the hinge-side thin upper wall 17 A force is applied to the end portion, the thin portion 17c is easily cut, then the thick portion 17a is cut, and the hinge-side thin upper wall 17 can be easily cut.

  After cutting the right cutting portion 14 and the hinge-side thin upper wall 17, when the upper lid B is further pulled in the left rotation direction and the hinge connecting portion 3d is pulled, as shown in FIG. While being pulled away from the outer cylinder 8, the left thin upper wall 15 is cut.

  After cutting the right cut portion 14 and the hinge-side thin upper wall 17, when the hinge connecting portion 3d is pulled, force is also applied to the left cut portion 13, but the upper longitudinal cut groove 13b of the left cut portion 13 is cut. However, since the lower inclined cutting groove 13c is inclined to the hinge C side, it is not cut due to resistance against the force in the left rotation direction, so the left cutting portion 13 is completely cut against the force in the left rotation direction. Can be prevented.

  When the left side wall portion 3b is separated from the outer cylinder 8 and further pulled, the left side wall portion 3b pulls the connecting portion 12, and further pulls and deforms the opposite side of the hinge C of the outer cylinder 8 so that the outer cylinder 8 and the mouth of the container When the engagement with the outer periphery of the tube portion is released and finally pulled upward, the cap body A can be easily removed from the mouth tube portion of the container and discarded.

  The hinge cap of the present invention can be easily removed from the container and separated and discarded without worrying about the direction in which the user rotates by right-handed or left-handed.

The hinge cap of the present invention has a left thin upper wall 15, a right thin upper wall 16, a hinge side thin upper wall 17 and a connecting portion 12 at the upper end between the inner periphery of the outer peripheral wall 3 and the outer periphery of the outer cylinder 8. Since the flat upper surface is formed, the liquid can be prevented from flowing between the outer peripheral wall 3 and the outer cylinder 8.
Further, since the window portions 18a and 18b are provided, when the left cut portion 13 or the right cut portion 14 is cut, the window portions 18a and 18b serve as a guide when the upper wall is cut.

  According to the present invention, in the hinge cap, the hinge cap can be easily removed from the container mouth portion and disposed by being selected and pulled by the user's intention in either the right rotation direction or the left rotation direction. It can be widely used as a hinge cap capable of separating and discarding containers of various contents.
