Description

  The present invention relates to a dispensing cap.

Conventionally, a cap body that is attached to a mouth portion of a container in which contents are stored and has a spout opening that opens in a direction intersecting the cap axis, and the cap body can be freely rotated via a connecting hinge portion. There is known a pouring cap provided with a cap-like cylindrical lid connected to the pipe, and a cap that protrudes into the lid so as to be detachable from the pouring port.
By the way, when the pouring cap is provided with a lid body that is rotatable around the connecting hinge portion and a cap body that has a spout opening that opens in a direction intersecting the cap axis, the lid body with respect to the cap body Only the pivoting movement around the connecting hinge part may cause the plug body to be caught on, for example, a dispensing cylinder having a spout, which makes it difficult to smoothly open and close the spout with less resistance. It was.
Therefore, as means for solving such a problem, for example, as shown in Patent Document 1 below, in the peripheral wall portion of the lid, in the cap axial direction, each portion connected to the connecting hinge portion from both sides in the cap circumferential direction. It has been proposed to form extending notches separately. In this case, the lid can be moved forward and backward along the opening direction with respect to the spout by sliding the lid with respect to the cap body while expanding and reducing the width of each notch. The outlet can be opened and closed smoothly with little resistance.

  However, in the conventional pouring cap, since the notch is formed in the peripheral wall portion of the lid, the lid cannot be sealed, and foreign matter may enter the lid from the outside through this notch. there were.

  The present invention has been made in consideration of such circumstances, and provides a pouring cap that can smoothly open and close the pouring port with little resistance without sacrificing hermeticity in the lid. For the purpose.

  In order to solve the above problems and achieve such an object, the pouring cap of the present invention is attached to the mouth of the container in which the contents are accommodated and opens in a direction intersecting the cap axis. A pouring cap comprising: a cap body in which an outlet is formed; and a cap-shaped tubular lid body rotatably connected to the cap body via a coupling hinge portion, the peripheral wall portion of the lid body A front wall portion that faces the spout, a main wall portion that is provided with a plug body that is removably fitted to the spout on the inner surface and that is disposed at a central portion in the circumferential direction of the cap, and a cap Outer wall portions disposed at both ends in the circumferential direction, and the outer wall portions are plate-like bodies that gradually extend inward in the cap radial direction from the outer side in the cap circumferential direction toward the inner side, Cap circumferential direction on the outer wall of the outer edge Outer edge constituting the outer edge is characterized by being composed by bending a deformable polygonal line portion leading to the open end from the end of the top side of the lid.

In this invention, when the open end side of the main wall portion in the front wall portion of the lid body is pulled toward the outside of the lid body, the broken line portion is bent and deformed, so that the outer wall portion is centered on the broken line portion. Rotate towards the outside of the body. Thereby, the main wall part of a front wall part also moves toward the outer side of a cover body, a plug body remove | deviates from a spout and this spout opens. Then, the spout is opened by rotating the lid body around the connecting hinge portion so as to be separated from the spout.
After that, the cover body is rotated around the connecting hinge portion with respect to the cap body so as to approach the spout, and the spout is covered with the cover, and then the main wall portion at the front wall portion of the lid is opened. When the end side is pushed toward the inside of the lid body, the broken line portion is bent and deformed, so that the outer wall portion rotates toward the inside of the lid body around the broken line portion. Accordingly, the main wall portion of the front wall portion also moves toward the inside of the lid body, so that the plug body fits into the spout and closes the spout.
From the above, when opening and closing the spout by the plug, the front wall of the lid is moved forward and backward with respect to the spout by bending and deforming the fold and turning the outer wall around the fold. The spout can be opened and closed smoothly with little resistance without sacrificing the hermeticity of the body.
Furthermore, when the spout is opened and closed by the plug, the outer wall is rotated around the broken line portion as described above, so that it is possible to easily ensure a sufficient amount of movement of the main wall with respect to the spout.

You may cross | intersect each other in the edge part of the said top part side in a wall part.

In this case, when the open end side of the main wall portion in the front wall portion of the lid body is pulled toward the outside of the lid body, the fold line portion is bent and deformed, and thus, of the two fold line portions defining the outer wall portion. The outer wall portion rotates toward the outer side of the lid, with the outer broken line portion positioned outside the circumferential direction of the cap in the front wall portion as the center. Thereby, the main wall part of a front wall part also moves toward the outer side of a cover body, a plug body remove | deviates from a spout and this spout opens. Then, the spout is opened by rotating the lid body around the connecting hinge portion so as to be separated from the spout.
After that, the cover body is rotated around the connecting hinge portion with respect to the cap body so as to approach the spout, and the spout is covered with the cover, and then the main wall portion at the front wall portion of the lid is opened. When the end side is pushed toward the inside of the lid body, the broken line portion is bent and deformed, so that the outer wall portion rotates toward the inside of the lid body around the outer broken line portion. Accordingly, the main wall portion of the front wall portion also moves toward the inside of the lid body, so that the plug body fits into the spout and closes the spout.
Further, the outer wall portion is formed in a triangular shape in plan view, one of the three outer edges thereof constitutes a part of the open end, and the other two are constituted by the broken line portion, and the top portion of the front wall portion is formed. Since the end portions on the side cross each other, the front wall portion can be easily deformed when the spout is opened and closed by the plug, and the opening and closing operability can be improved reliably.

Further, at the both ends of the main wall portion in the circumferential direction of the cap, a sub-wall portion protrudes toward the inside of the lid, and the sub-wall portion is connected to the outer wall portion via the broken line portion. Also good.
In this case, when the open end side of the main wall portion of the lid body in the open position is pushed toward the inside of the lid body, it becomes possible to efficiently transmit the force from the sub-wall portion to the outer wall portion. .

Further, the front wall portion may be disposed on the opposite side of the connecting hinge portion with the cap shaft interposed therebetween.
In this case, since the front wall portion is disposed on the opposite side of the connecting hinge portion across the cap shaft, the opening and closing operation of the spout by the plug body and the rotation operation of the lid body with respect to the cap body are poured out. It becomes possible to carry out continuously with substantially the same operation on the same portion of the cap, and it is possible to provide a high opening / closing operability.
