Therefore, the cap was difficult to remove from the container. In order to solve this problem, there is a cap provided with a thin weak line for separation and collection in the cap body to make it easy to separate the cap from the container, but it is still not sufficiently stable and easy to separate, In addition, the thin impacted line breaks due to an external impact during distribution, causing a liquid leakage accident, a weak fitting force of the cap to the container, a entanglement of the cap by the separation knob in the filling line, and a closure by a pull ring. It was difficult to open the plate. Further, in the case of a snap hinge, there are some hinge hinges having a large protrusion or poor snap properties.

0), the mouth and neck (2) of the container (20)
An occlusal ring (115) is provided which is engaged with and engaged with the occlusal ring (22) provided in 1), and the inner peripheral surface of the upper end of the peripheral wall (110) is engaged with the occlusal ring (223) of the lid. A recessed closing plate (120) is provided on the upper surface of the occlusal ring tube (126) to be fitted and the pouring tube (127) provided on the inside thereof, and the inside of the peripheral wall (110) is sealed. An annular thin weak line (122) having an arbitrary shape is formed at a position where the sealing plate is to be opened, and an annular thin weak line is formed on one side of the upper surface near the inside of the annular thin weak line. A contact sealing ring (129) that stands upright on a support (123) having a pull ring (124) and that normally seals the container on the lower surface in close contact with the top surface of the mouth of the container mouth and neck (21). And an inner sealing ring (12) for sealing the container in close contact with the inner peripheral surface of the mouth of the container. ) And is intended to provide. Note that the contact sealing ring and the inner sealing ring are provided as necessary. Further, as shown in FIG. 1, the cap body (100) is attached to the outer peripheral surface of the upper end portion at a position near one side (the lower side in the figure) of the hinge (300) of the peripheral wall (110). Knob (13) having a handle (132) parallel to the outer peripheral surface of the peripheral wall in the direction
FIG. 3 and FIG. 4 at a position adjacent to one side of the hinge of the root (131) of the separating knob of the peripheral wall (110).
The slit (111) shown in FIG.

く、また、手を痛めることもない。In the above-described plastic cap of the present invention, since the thin weak line continuous to the peripheral wall of the cap body and the sealing plate is formed, the cap is easily separated from the container when the container is disposed after use. It is possible,
Separation and collection becomes easy. That is, the cap fitted to the mouth and neck of the container, the handle portion of the separation knob attached to the peripheral wall of the cap is raised by a finger and pulled in the circumferential direction on the other side of the hinge, the slit provided in the peripheral wall As a result, the peripheral wall continuous to the slit and the thin weak line of the sealing plate are torn, and the peripheral wall on the opposite side of the hinge becomes large (for example, in FIG. 3, the central angle is approximately 260 degrees).
To separate. As a result, the force of fitting the cap to the mouth and neck of the container is weakened, and the cap can be easily separated from the container by pulling the lid with a finger. Therefore, at the time of removal, the liquid contents adhering to the container are less scattered, and the hands are not hurt.

By increasing the thickness of the drainage groove and the thin fragile line for separation and collection provided in the vertical direction from below to above, the fitting force to the container mouth and neck can be increased, and there is a risk of liquid leakage during distribution and storage. Absent. Further, by providing the lid with the entanglement preventing projection, entanglement of the caps caused by the sorting knob on the filling line is prevented, and high-speed filling is enabled. In addition, by forming the upper end of the column standing on the closing plate in a V-shape and connecting the pull rings continuously, it becomes easy to tear the annular thin line of weakness of the closing plate, and furthermore, the vertical support supporting the back surface of the column. By providing the rib, the annular thin weak line of the sealing plate can be torn with a relatively small force, and the container can be easily opened at the time of use.
