In this embodiment, the separation disposal cap is a hinge cap. However, the upper lid is not necessarily a hinge cap connected to the cap base by a hinge, and the upper lid is separate from the cap base and is made of screws, snaps, etc. The thing provided with the connection part may be sufficient.
Further, the shape of the fitting tube portion is limited to the shape having the fitting inclined surface 30, the fitting vertical surface 31, the bulging ring 32 and the like corresponding to the shape of the mouth portion 1 of the container body as in this embodiment. However, the same effect can be expected as long as it fits into the mouth portion by an interference fit.
Further, the circumferential tear line is not limited to the aspect of the present embodiment, and any form continuous to the longitudinal tear line is possible, and if the fitting cylinder portion has a function of releasing from the mouth portion, the circumferential tear line is possible. There is no need.

Next, usage modes and operational effects of this embodiment will be described.
The cap for waste disposal according to the present embodiment is filled with the contents in the container body D, and then the fitting cylinder portion 8 is applied to the mouth portion 1 in the closed state shown in FIG. Mount on the container body D.
At this time, the cap can be positioned by the top of the bent portion 37 protruding from the outer peripheral surface of the outer cylinder 11, and the cap can be plugged in accordance with the direction of the container body D.

When a pressing force is applied from above the upper lid B by the stopper, the outer cylinder 11 is pushed and opened along the inclined surface 2 of the fitting protrusion 4 as the mouth portion 1 is fitted into the fitting groove 14. The diameter is expanded outward.
At this time, the thinned weakened portion 35 in which the vertical tear line E is formed is relaxed by the extension of the bent portion 37, the tensile force due to the diameter expansion of the outer cylinder 11, and the deformation of the thinned weakened portion 35. Breakage can be reliably prevented.
When the fitting of the mouth part 1 into the fitting groove 14 proceeds and the bulging ring 32 gets over the vertical surface 3 and engages the constricted part 5, the stoppering is completed and the separation waste cap is attached to the mouth part 1 [See FIG. 2 (a)].

Since the inner peripheral surface of the outer cylinder 11 is formed with a slightly small diameter so as to have a predetermined allowance with respect to the outer peripheral surface of the mouth portion 1, the mouth portion 1 is completely fitted in the fitting groove 14. In this state, the outer cylinder 11 is enlarged in diameter by the tightening allowance.
As shown in FIG. 4 (b), the bent portion 37 of the thinned weakened portion 35 is extended to the outer peripheral surface of the outer tube 11 when the plugging is completed and the outer tube 11 is enlarged by the above-mentioned tightening allowance. A flush surface is formed.
Thus, the container equipped with the sorting and disposal cap of the present embodiment in which the bent shape of the thinned weakened portion 35 is set is excellent in appearance and does not catch or break the thinned portion when handling the container.
As described above, the extended bent portion 37 may protrude to the extent that a mark on the bent top portion remains, and in some cases, there is an allowance for the bulging ring 32 to get over the fitting ridge 4 at the time of plugging. The bent shape may be set by expecting, and the bent portion 37 may protrude from the outer peripheral surface of the outer cylinder 11 without being completely extended when the cap is attached.

As described above, the bent portion 37 has a shape in which the bent top portion protrudes toward the notch 36 (see FIG. 5A) or a bellows shape in which the bent portion 37 is repeatedly bent. [See FIG. 5 (b)].
In the case where the bent portion 37 protrudes toward the notch portion 36 and is formed inside the outer peripheral surface of the outer cylinder, the thinned weakened portion 35 having a bent shape is not caught or damaged when the cap is handled. .
Further, in the case where the bent portion 37 has a bellows shape that is repeatedly bent, the bending height with respect to the extension allowance can be reduced, so that the shape of the cutout portion 36 can be afforded, and design freedom is achieved. The degree can be increased.

When the container is filled with high-temperature contents for sterilization, it is washed and cooled by applying shower water from outside the container after the stoppering process.
At this time, shower water may enter the cap, but even if the shower water that has entered the cap flows into the slit groove 41, a drain hole 47 is provided in the bottom surface 43 of the slit groove 41. Therefore, the shower water that has flowed in flows out from the lower end of the cap through the drain hole 47 through the drain hole 48.
Further, when the cap internal pressure is increased by the high-temperature filling, the top wall 50 is deformed so as to swell by the internal pressure absorbing thin-walled portion 53 and the increase in the cap internal pressure is suppressed, so that inadvertent opening of the cap can be prevented.

In order to use the container attached with the hinge cap for separation and disposal of the present invention, the finger is put on the knob 58 and the upper lid B is lifted to open the lid, the pull ring 23 is pulled upward to break the weakened portion 22, and the partition wall 18. The removal part 21 is cut out from the opening to open the spout.
At this time, the pull ring 23 is formed with a gripping portion provided with a finger contact piece 25 on the lower side on the opposite side of the hinge C, so that the fingertip does not hurt when opened.

After using a container, the aspect which separates and discards the cap of a present Example is demonstrated.
First, when the hinge cap of the present invention is opened and the upper lid B is gripped and pulled outward, the connecting portion with the hinge C of the outer cylinder 11 is pulled and deformed, and the vertical direction formed by the thinned weakened portion 35 Along the tear line E, the outer cylinder 11 is torn in the vertical direction from the top.
At this time, the thinned weakened portion 35 often breaks from the vicinity where the top of the bent portion 37 was formed, but depending on the pulling force, the thinned weakened portion 35 may break from the vicinity of the end on the hinge C side. It may be broken from any part of the throat.
If a weakened portion such as a perforation is provided at the top of the bent portion 37, it can be broken more easily.

When the break in the longitudinal tear line E proceeds and the upper portion of the outer cylinder 11 begins to deform outward due to the outward pulling force, the weakened thin-walled connecting portion 42a that forms the starting point of the circumferential tear line F breaks. Begin.
Since the weakened thin-walled connecting portion 42a is formed to be extremely thin or to be broken and easily broken, even if the breaking direction changes from the longitudinal tear line E to the circumferential tear line F, it can be smoothly broken. Can proceed.

When the breaking of the vertical tear line E is completed, the breaking of the weakened thin-walled connecting portion 42a proceeds and the upper lid B moves away from the cap base A.
Then, the breakage easily proceeds to the end of the weakened thin-walled connecting portion 42a, the upper lid B is greatly separated from the cap base A, and further reaches the steady thin-walled connecting portion 42c while increasing the tearing force at the transition thin-walled connecting portion 42b. Breaking proceeds with a constant tearing force.
When the upper lid B is greatly separated from the cap base A, a force for pulling the upper lid B is easily applied. Therefore, the upper lid B can be easily broken even if the tearing force increases from the transition connecting portion 42b.

When the cutting to the end surface 44 of the slit groove 41 is completed and the upper lid B is further pulled, the end connecting portion 45 where the outer cylinder 11 is firmly connected to the base wall 12 is pulled outward and deformed, and the cap is It is separated from the mouth 1 and can be separated and discarded.
As described above, in the separation disposal cap of the present embodiment, the thinned weakened portion 35 that forms the longitudinal tear line E has a bendable shape that is stretchable. Even when fitted to the portion 1, the bent shape extends and the pulling force is relaxed, and the thinned weakened portion 35 is not inadvertently broken.
Moreover, when fitted to the container body D, the bent shape extends to form a peripheral surface that is flush with the outer peripheral surface of the outer cylinder 11, so that the same appearance and usability as a normal container can be obtained and a sense of incongruity is obtained. Absent.

  The separation waste cap of the present invention is formed by a thinning weakened portion that can tear the fitting tube portion with a small force at the time of sorting and discarding. Therefore, it is safe and easy to use, and can be widely used as a separate disposal cap for food containers suitable for a wide range of ages such as children and the elderly.
