  The above-described prior art is provided with an opening into which the outlet of the inner plug is inserted on the top surface, and a cap body that is attached to the mouth of the container with the inner stopper attached, and a hinge that can swing on the cap body. In the snap cap composed of a lid body that is connected at the back and has a plug body projecting from the discharge port on the back surface, the plug body is composed of a plurality of cylindrical protrusions arranged concentrically, and One cylindrical projection is fitted to a discharge port with a different inner diameter of different inner plugs so that the plugs can be closed.

  That is, a plurality of inner plugs having different outlet diameters are provided, and separately from the inner plug, a plurality of cylindrical protrusions that are closely fitted in a one-to-one correspondence with the outlets of each inner plug are provided integrally. By forming a snap cap having a lid and replacing the inner stopper for the container, the discharge degree of the content liquid can be switched and changed.

  However, in the above-described prior art, in order to switch and change the discharge level of the content liquid, since the operation of replacing the inner stopper with respect to the container is performed with the snap cap removed from the container, There is a problem that it is very troublesome to change and change the discharge level of the content liquid during the discharge.

  That is, for example, in a hot cake or the like, it is desirable not only to discharge and apply the content liquid such as syrup but also to change the discharge port to be small when drawing characters or designs with the discharged content liquid. However, since the above-described conventional technique requires replacement of the inner plug, it is extremely troublesome to satisfy this demand.

  In addition, in order to be able to change and change the discharge level of the content liquid, it is necessary to prepare an inner plug that is separate from the inner plug attached to the container at hand, For this reason, there was a problem that the handling was troublesome.

  Therefore, the present invention was devised to solve the above-described problems in the prior art, and it is a technical problem to integrally provide discharge cylinders having different diameters so that the discharge degree of the content liquid can be switched. For the sake of simplicity, an object is to obtain a preferable discharge form of the content liquid.

The discharge cap according to the present invention has a main discharge cylinder standing upright and can be tightly fitted to the main discharge cylinder of the cap main body, and can be tightly fitted to the main discharge cylinder of the cap main body. It has one discharge cylinder that has a sub-discharge cylinder that has a smaller diameter than the discharge cylinder, and an open / close lid that opens and closes the sub-discharge cylinder of this discharge cylinder. The cylinder body and the opening / closing lid body are hinge-coupled, and the hinge coupling portion with the cap body side of the discharge cylinder body and the hinge coupling portion with the opening / closing lid body side are positioned on the opposite side.

  The cap body is configured by erecting a main discharge cylinder upright on an assembled cylinder that is tightly attached to a mouth tube portion of a bottle-shaped container body.

The discharge cylinder communicates with the tightly fitting cylinder piece on a top plate in which a tightly fitting cylinder piece that can be closely fitted into the main discharge cylinder of the cap body is suspended, and has a smaller discharge than the main discharge cylinder of the cap body. It is constructed by standing up a cylinder. In addition, the force due to the surface tension of the content liquid in the closely-fitting cylinder piece prevents the “content drawing” from occurring on the discharged content liquid, and the content liquid remaining in the sub-discharge cylinder The length of the tightly fitting tube piece is set so as to be strong enough to pull the tube into the container. In addition, a drooping cylinder piece is provided in communication with the main discharge cylinder, and the force due to the surface tension of the content liquid in the drooping cylinder piece causes the liquid to be discharged into the thread. The length of the drooping cylinder piece is set so that it is prevented from occurring and the strength of the content liquid remaining in the main discharge cylinder is drawn into the container.

  The open / close lid opens and closes the sub-discharge cylinder of the discharge cylinder by attaching and detaching it closely to the opening of the sub-discharge cylinder.

The hinge coupling between the cap main body and the discharge cylinder body allows the close-fitting cylinder piece of the discharge cylinder body to be tightly fitted into the main discharge cylinder of the cap main body, and the hinge between the discharge cylinder body and the opening / closing lid body The coupling is such that the sub-discharge cylinder of the discharge cylinder can be opened and closed with an opening / closing lid. Since both hinge joints are located on the opposite side, the discharge port is switched between large and small, and when the large discharge port is opened and when the small discharge port is opened, The moving direction is opposite, and the height position of the hinge coupling portion that opens and rotates is greatly different.

  When the cap body, the discharge cylinder, and the open / close lid are combined, the discharge cap is in the “closed” state. When the open / close lid is rotated from this state, the secondary discharge cylinder of the discharge cylinder is discharged. When the assembly of the discharge cylinder body and the opening / closing lid body is opened and rotated separately, the main discharge cylinder of the cap body is opened as the discharge opening of the discharge cap.

  That is, by switching between opening rotation of only the opening / closing lid and opening rotation of the combination of the discharge cylinder and the opening / closing lid, the discharge port of the discharge cap to be opened is made larger than the small-diameter sub-discharge cylinder. Switching to one of the main discharge cylinders of the caliber.

  In this way, switching of the discharge port of the discharge cap to be opened is achieved by which hinge coupling is operated to open, and the cap body, the discharge cylinder body, and the opening / closing lid body are hinged together instead of a single item. It has become.

The length of the closely-fitting cylinder piece prevents the occurrence of “liquid drawing in the form of a thread” against the discharged content liquid due to the required surface tension, and the contents remaining in the sub- discharge cylinder the liquid, since the set intensity value serving to draw the container body, the discharging operation of the content liquid from the secondary discharge tube, it is possible to obtain a good liquid out state, the content liquid remaining in the secondary discharge cylinder Quick return to the container can be obtained.

The length of the drooping cylinder piece provided in communication with the main discharge cylinder prevents the occurrence of "liquid drawing in the form of thread" with respect to the discharged content liquid due to the required surface tension. the content liquid remaining in the main discharge cylinder, since the set intensity value serving to draw the container body, the discharging operation of the content liquid from the main discharge tube, it is possible to obtain a good liquid out state, the main The content liquid remaining in the discharge cylinder can be quickly returned to the container body.

  In addition, another configuration of the present invention is such that the outer diameter of the tightly fitting cylinder piece is set to be equal to or slightly smaller than the inner diameter of the drooping mouthpiece piece, and the length of the tightly fitting cylinder piece is set to the cap body and the discharge cylinder In a state where the body is assembled, the value is set so as not to protrude downward from the inside of the hanging mouth piece.

  In the case where the outer diameter and length of the tightly fitting cylinder piece with respect to the hanging mouth cylinder piece are set, in the state where the cap body and the discharge cylinder body are combined, Since the outer peripheral surface is covered with the drooping tube piece with almost no gap, even if the container body is turned upside down, the content liquid hardly adheres to the outer peripheral surface of the tightly fitting tube piece.

  In another configuration of the present invention, the outer diameter of the tightly fitting cylinder piece is set to a value that is equal to or slightly smaller than the inner diameter of the drooping mouthpiece piece. In the state where the cylinder is assembled, the lower end of the hanging port cylinder piece is set to a value located below the lower end of the tightly fitting cylinder piece.

  If the length of the tightly fitting tube piece is set to a value such that the lower end of the drooping tube piece is positioned below the lower end of the tightly fitting tube piece, it will adhere to the drooping tube piece and the close fitting tube piece. Due to the length, most of the content liquid that flows down adheres to the drooping cylinder piece side and does not adhere to the tightly fitting cylinder piece side.

  Moreover, another structure of this invention forms the cutting part which is an open part in the lower front side part of the close fitting cylinder piece.

  In the case where the cut portion is formed in the lower front portion of the close fitting cylinder piece, when the close fitting cylinder piece is attached to and detached from the main discharge cylinder, the close fitting cylinder piece is prevented from being caught on the inner peripheral edge of the main discharge cylinder. be able to.

  Moreover, another structure of this invention forms the notch which is an open part in the lower front side part of a drooping opening cylinder piece.

  In the case where a notch is formed in the lower front side portion of the drooping opening cylinder piece, it is possible to prevent the drooping opening cylinder piece from interfering with the attaching / detaching operation of the tightly fitting cylinder piece with respect to the main discharge cylinder. be able to.

  Another configuration of the present invention is such that a relief portion is formed by reducing the height at the rear portion of the main discharge cylinder.

  In the case where a relief portion is formed in the rear portion of the main discharge cylinder, the main discharge cylinder itself is prevented from interfering with the attaching and detaching operation of the tightly fitting cylinder piece to the main discharge cylinder. Can do.

Another configuration of the present invention, between the lid member and the cap body and the discharge cylinder body, provided with a locking function portion for holding a combinatorial product of the discharge cylinder body and the lid member to the open position , That is.

Closing the discharge cylinder body and the apparatus having provided a locking function portion holding the open position The combined product-closing lid, the locking function portion, closing the lid in the open position, or the discharge cylinder body and The combination with the lid is held in an open position so as not to obstruct the discharge operation of the content liquid.

  Further, according to another configuration of the present invention, a hinge that couples the cap body and the discharge cylinder is a main hinge having a self-position holding force, and the opening / closing lid is opened between the cap body and the opening / closing lid. It is provided with a locking function part for maintaining the posture.

  The cap body and discharge cylinder are connected by a main hinge that has a self-position holding force, and a locking function part is provided between the cap body and the opening / closing lid body. The main hinge opens the combination of the discharge cylinder and open / close lid in the open position, and the locking function opens the open / close cover in the open position so as not to obstruct the discharge operation of the liquid contents. Hold in posture.

When the discharge cylinder is opened and rotated, it is possible to prevent the occurrence of inconveniences such as the content liquid adhering to the close-fitting cylinder piece splashing due to the momentum of the close-fitting cylinder piece coming out of the main discharge cylinder. And a good use situation can be obtained.

  In the case where the length of the tightly fitting cylinder piece is set to a value where the lower end of the drooping mouth piece is located below the lower end of the tightly fitting cylinder piece, most of the content liquid adheres to the tightly fitting cylinder piece side. Therefore, it is possible to sufficiently suppress the close-fitting cylinder pieces from scattering the content liquid during the opening operation.

  In the case where the cut portion is formed in the lower front portion of the close fitting cylinder piece, when the close fitting cylinder piece is attached to and detached from the main discharge cylinder, the close fitting cylinder piece is prevented from being caught on the inner peripheral edge of the main discharge cylinder. As a result, a smooth opening / closing operation with respect to the cap body of the discharge cylinder can be obtained, and a favorable handling situation can be obtained.

  In the case where a notch is formed in the lower front side portion of the drooping opening cylinder piece, it is possible to prevent the drooping opening cylinder piece from interfering with the attaching / detaching operation of the tightly fitting cylinder piece with respect to the main discharge cylinder. Therefore, a smooth opening / closing operation with respect to the cap body of the discharge cylinder can be reliably obtained.

  In the case where a relief portion is formed in the rear portion of the main discharge cylinder, the main discharge cylinder itself is prevented from interfering with the attaching and detaching operation of the tightly fitting cylinder piece to the main discharge cylinder. Therefore, the opening / closing operation of the discharge cylinder with respect to the cap body can be made stable and easy.

In the ones that provided a locking function portion for holding a combinatorial product of the discharge cylinder body and the lid member to the open position, the locking function portion, closing the lid in the open position, or a discharge tube body Since the combination with the opening / closing lid is held in an open posture so as not to disturb the discharge operation of the content liquid, the discharge of the content liquid can be achieved safely.
