However, in the conventional spout part, the removal part is cut along the cutting groove by pulling the pull ring upward. However, when the cutting part is cut inside the removal part, the thin part above the cutting groove extends upward. In some cases, a burr portion was formed on the bottom wall in contact with the spout.
At that time, after the content liquid is poured out, there is a problem that the liquid remaining in the bottom wall of the dispensing cylinder stays in the burr portion and does not return into the container.
Even when the bottom wall is inclined, it flows through the groove formed in the burr portion and stays at the lowest position, and the staying liquid does not return into the container.

An object of the present invention is to provide a cap that forms a spout that is provided with a notch portion in which a burr portion is not formed at the lowest portion and returns the content liquid into the container. Objective.

In order to solve the above-mentioned problems, the present invention provides a partition wall continuously provided at a lower end portion of the inner periphery of a dispensing cylinder, as a spout for a cap, with a removal wall that is partitioned by a cutting groove and forms a spout. A step is provided between the upper surface of the removal wall and the upper surface of the removal wall, with the removal wall on the lower side, and a thin portion is formed between the step groove and the cutting groove formed on the lower surface, and the thinnest portion of the lowest portion of the cutting groove In addition, by providing a cut part consisting of a short fracture part on the peripheral edge side of the partition wall and a rib-shaped part thicker than the fracture part on the removal wall side , a burr part is formed at the lowest part around the spout when the removal wall is unplugged. A configuration is adopted in which a notch portion that is not provided is provided so that the liquid can be returned.

As another embodiment of the cap of the present invention, a partition wall provided at the lower end of the inner periphery of the dispensing cylinder is provided with a removal wall that is partitioned by a cutting groove to form a spout, and the upper surface of the partition wall and the upper surface of the removal wall are provided. A step is provided with the removal wall on the bottom, a thin portion is formed between the step surface and the cut groove formed on the lower surface, and the depth of the groove is reduced in the thin portion at the lowest portion of the cut groove. A protrusion projecting downward and a projection projecting slightly on the partition wall side in a plan view, and the protrusion has an end that is thinner than the projection on the partition wall side. A configuration is adopted in which the portion is extended and a notch portion in which no burr portion is formed is provided at the lowest portion around the spout when the removal wall is plugged, so that the liquid can be returned.
In addition, as an embodiment of the cap of the present invention, a configuration is adopted in which a pair of liquid dripping ribs are vertically provided on the partition wall facing the lowest part of the cutting groove.

The cap of the present invention is provided with a step between the partition wall and the removal wall forming the spout so that the removal wall is on the lower side, forming a thin portion between the step surface and the cutting groove, Since a part of the thin wall portion was narrowed, the burr portion formed at the time of removing the removal wall was notched, and the liquid staying in the partition wall was returned to the container after the liquid was poured out.
In addition, when the liquid dripping rib was provided along the cutting groove in the short diameter part, the liquid return could be further improved.

  In FIG. 1, A is a cap base, and B is a lid that is connected to the cap base A by a hinge C.

As shown in FIG. 1, the cap base A includes a fitting cylinder 1 that is fitted to the container mouth portion, and a dispensing cylinder 2 that is connected to the fitting cylinder 1.
The fitting cylinder 1 includes an inner cylinder 3, an outer cylinder 4, and an upper wall 6 in which a lid engaging portion 5 is erected.
A connecting wall 7 that protrudes inward from the lower end of the inner cylinder 3 protrudes, and an extraction cylinder 2 is erected from the inner edge of the connecting wall 7.
A partition wall 8 is connected to the lower end portion of the dispensing tube 2, and a removal wall 9 for forming a spout is defined in the center of the partition wall 8 by a cutting groove 10.

As shown in FIGS. 1 and 2, the planar shape of the removal wall 9 is a shape close to a quadrangle whose longitudinal direction is the pouring direction, but a step 11 is provided between the partition wall 8. In addition, a thin portion 12 is formed between the cut groove 10.
The vertical cross-sectional shape of the removal wall 9 is a concave portion whose central portion is recessed along the center line of the long diameter portion, and the short diameter portion of the removal wall 9 is a crossing line of the folded curved surface.
The short diameter portion is formed significantly below the peripheral edge of the partition wall 8, and the partition wall 8 is inclined toward the thin portion 12 around the removal wall 9.

  In the above embodiment, the shape of the removal wall is a quadrilateral, but it may be oval or circular, and the longitudinal cross-sectional shape may be a curved concave portion at the center, and the short diameter portion is folded. It does not have to be a curved intersection line.

In the short diameter portion, the cut groove 10 is formed with a deformed cut groove 15 including a thin short break portion 13 and a rib-shaped portion 14 following the break portion 13.
In addition, a pair of liquid dripping ribs 16 are suspended from the periphery of the short-diameter partition wall 8 in contact with the fracture portion 13.
A pull ring 18 is connected to a predetermined position of the removal wall 9 via a support column 17.

  In the embodiment, the short diameter portion of the removal wall 9 is the lowest portion of the cutting groove, but it may be the lowest portion of the cutting groove on the periphery of the removal wall corresponding to the shape of the removal wall 9.
