In the hinge caps described in Patent Documents 1 and 2, as described above, the cap body is separated ( removed ) from the container by cutting off the hem portion of the outer cylindrical body of the cap body. Since there are no clues for hooking the fingertips to cut off the hem portion of the outer cylinder, it is extremely difficult to separate the outer cylinder from the container, and the fingertips are injured or cannot be separated . There was a risk of becoming .

  In particular, in the hinge cap of the type described in Patent Document 1, a longitudinal weakening line for cutting off the hem portion of the outer cylindrical body of the cap body is provided with a hinge for connecting the lid to the cap body. Since it is located at a place, there is a problem that the hinge part is broken.

The present invention is directed to the technical problem of providing a Hinjikya' flop which overcomes these problems.

The hinge cap of the present invention is
“A cap body that is attached to the mouth portion of the container and a lid body that is openably and closably connected to a side surface of the cap body via a hinge. The cap body fits into the mouth portion of the container from the outside. While having an outer cylindrical body, a tab for finger hooking is provided on the opposite side of the lid from the hinge,
A circumferential weakening line that extends in the circumferential direction so as to surround the outer cylindrical body from the opposite side of the hinge and has both ends positioned on both sides sandwiching the hinge, and both ends of the circumferential weakening line. Forming a pair of left and right longitudinal weakening lines that extend continuously to the lower end of the outer cylindrical body, thereby forming a separation piece that can cut out a portion surrounded by the circumferential weakening line and the left and right longitudinal weakening lines. "
This is the basic configuration.

And
“On the outer periphery of the outer cylindrical body of the cap body, an engaging piece for preventing tampering that engages with the tab of the lid body is flattened on the outer side of the outer cylindrical body. It is provided so as to extend in an arc shape when viewed and can be shredded.
Further, a tab that protrudes outside the outer periphery of the engagement piece in a state of extending in an arc shape in a plan view is provided at two left and right positions between the hinge and the engagement piece on the outer periphery of the engagement piece in the cap body. `` It is provided integrally, and the left and right knobs are formed with a free end for the person to pick and pull, extending toward the hinge. ''
It has the characteristics.

In the present invention, when at least one of the left and right knob pieces is picked and pulled with a fingertip, the separation piece of the fitting cylinder in the cap body has a circumferential weakening line that surrounds and forms the separation piece, and Since it tears along the longitudinal weakening line and is cut off and separated from the outer cylinder, the entire hinge cap can be separated (removed) very easily from the container. Injuries to the fingertips and inseparability can be reliably reduced.

  In addition, the longitudinal weakening lines for forming the separation pieces are provided in portions adjacent to the left and right sides of the hinge, thereby avoiding the possibility that the hinge will be broken, Since the knobs for the sorting piece are provided on both the left and right sides, even if one of the knobs is broken, it can be reliably separated by the other knob.

The front SL because the left and right both knob pieces are arcuate in shape with the flat surface view, yet in this that can reduce that other object is caught during use as a hinge cap, than the outer cylinder by projecting radially outward, there is an advantage that separation can be more easily from the free end portion easily try grasped with a finger tip container.

Meanwhile, the hinge cap is intended to be mounted to be fitted-relative container in the closed state of the lid against the caps body, in this mounted, the hinge cap, in a line along the rail A method of transporting them side by side and mounting them one by one from the tip is adopted.

  In this case, when the hinge cap is of a type in which an engagement piece for preventing unauthorized opening is provided at a portion of the lid opposite to the hinge, the illegal movement of the hinge cap during the one-line transport by the rail of the hinge cap It is necessary to hold the unsealing prevention engagement piece in a state in which the cores are aligned so that the engagement piece is directed in a certain direction in a plan view and the displacement in the lateral direction is small.

In the present invention is contrast, by arcuate the knob piece is position on both sides of the left and right in a plan view, when transferring the hinge cap in a row along the rail, it picked both of the right and left since pieces performs the action of the guide, in plan view, toward the engaging piece for preventing tampering in a predetermined direction, and, as displacement movement air in the lateral direction is small, certainly in a state of aligning the core There is an advantage that can be retained.

For example, as can be seen from FIGS, portions close to the left and right sides of the hinge 4 and 5 of the outer cylinder 8 in the cap body 2, the inner circumferential surface of this two downwardly extending axially 1 longitudinal weakening line 22 and two second longitudinal weakening lines 23 extending on the outer peripheral surface in the downward axial direction, both of the first and second longitudinal weakening lines 22, 23, The cross section is a square groove type and extends to the lower end edge of the outer cylindrical body 8. In particular, the first longitudinal weakening line 22 on the inner peripheral surface is provided on the inner peripheral surface as shown in FIG. The second longitudinally weakened line 23 is located close to the outside of the first longitudinally weakened line 22, and the outer cylindrical body 8 is torn between them. .

For example, as shown in FIG. 5, a portion of the inner peripheral surface of the outer cylindrical body 8 opposite to the hinges 4 and 5 extends in the circumferential direction and has an end portion at the first longitudinal weakening line 22. A first circumferential weakening line 24 is provided, and further, a groove shape is formed on the top surface of the top plate 10 of the cap body 2 on the side opposite to the hinges 4 and 5 so as to extend in the circumferential direction . A two-round weakened line 25 is provided, and the bottom surface of the second peripheral weakened line 25 is close to the first peripheral weakened line 24, and the outer cylinder 8 is torn between the two peripheral weakened lines 24, 25. It has a configuration.

Accordingly, the hinge 4, 5 and the portion surrounded by a vertical line of weakness 22 and 23 located on the opposite side of the peripheral weakened line 24, 25 of the outer tubular body 8, the vertical line of weakness 22, 23及beauty it is configured to fractional piece 26 that can be separated while breaking-away along a circumferential line of weakness 24 and 25.

In the drawing, the first circumferential weak line 24 is configured to go around the entire inner circumferential surface of the outer cylindrical body 8, but the first circumferential weak line 24 is configured to travel around the inner circumference of the outer cylindrical body 8. It can be set as the structure which communicates only between the said 1st both vertical weakening lines 22 among surfaces. Further, the second circumferential weakening line 25 may be provided at the base portion of the outer cylinder 8 with respect to the top plate 10 instead of being provided on the top surface of the top plate 10.

Then, as shown in FIG. 3 and FIG. 7, the portion between the hinges 4, 5 and the engagement piece 20 on the left and right sides of the outer cylindrical body 8 of the cap body 2 is seen in plan view. A knob piece 27 having an arc shape is disposed at a position spaced radially outward from the outer peripheral surface of the outer cylindrical body 8, and both the knob pieces 27 are integrally connected to the upper end of the separation piece 26. doing. Further, the both knobs 27 are provided with free ends 27a extending in an arc toward the hinges 4 and 5 beyond the second longitudinal weakening line 23 .

In the above configuration, when the free end 27a of at least one of the left and right knobs 27 is picked and pulled by a fingertip, the portion 26 of the outer cylinder 8 in the cap body 2 is separated. , torn torn along the longitudinal line of weakness 22, 23及BiAmane weakened line 24, 25 you formed surrounds the separation piece 26, as shown in FIG. 10, to be cut separated from the outer tubular member 8 Therefore, the entire hinge-type cap 1 can be separated (removed) from the container 6 very easily.
