Moreover, the cap 27 combined with this container 21 has an outer cylinder 28 that reaches the shoulder 23 of the container 21,
It consists of an inner cylinder 29 provided inside this outer cylinder 28 at a certain interval, and a sealing member 30 provided inside this inner cylinder 29 with a gap, and is made of, for example, a soft synthetic resin such as polypropylene. It is integrally molded. The outer cylinder 28 is provided with two bent pieces 31, 31 for removing and removing the cap, which are pressed when the cap is opened.
This bent piece 31 for attaching and detaching the cap has two notches 3 extending vertically from the lower end of the outer cylinder 28 to a position slightly lower than the upper surface 32 of the cap.
3 and 33, and the outer cylinder of the portion sandwiched by the notches 33 and 33 is bent to have a substantially doglegged cross-sectional shape so that its lower end faces inward to the cap 27. This bent piece 31 for attaching and removing the cap can also be bent inward at its tip so that the bent part 31a can be attached to the outer cylinder 2 as shown in FIG.
The bent portion 31a protrudes outward from the outer circumferential surface of the container 21, but the dimensions, shape, etc. can be determined so that the protruding bent portion 31a is located inward than the outer circumferential surface of the body 22 of the container 21. preferable. The bent pieces 31, 31 are provided with knurled grooves in the horizontal direction. Further, the lower part of the inner cylinder 29 is a hook-shaped locking pawl 34 that engages with the locking protrusion 26 of the neck portion 24, and furthermore, the movement of this locking pawl 34 is facilitated, and the locking is smooth. A plurality of slits 35 are formed in the lower part of the inner cylinder 29 for this purpose. Furthermore, the sealing member 30 is formed to have a fitting inner diameter slightly larger than the opening, and its tip becomes gradually thinner and curved in the radial direction.

Therefore, in order to seal the container 21 having such a structure with the cap 27, the cap 27 is moved downward. That is, when the inner cylinder 29 is placed over the neck 24, the locking pawl 34 first comes into contact with the neck 24. At this time, the neck 24
Since the contact surfaces of the cap 27 and the inner cylinder 29 are approximately parallel to the axial direction as described above, the centering (alignment) of the cap 27 is performed by the fitting operation.
This prevents the phenomenon that the cap 27 is tilted due to the inevitable tilting of the cap 27. As the cap 27 descends, the tip of the sealing member 30 is accurately fitted into the opening 25, and the sealing member 30 is elastically deformed to tightly seal the opening 25. Then, the locking claw 34 at the tip of the inner cylinder 29 locks into the locking protrusion 26, and the cap 27 is firmly fixed to the container 21.

Furthermore, when removing the cap 27 from the container 21, it is sufficient to pinch the bent portion 31a of the bent piece 31 of the outer tube 28 for removing and pushing the cap toward the center. By this operation, the tip of the bent piece 31 is connected to the container 21.
The pinching force is converted into a force that pushes the entire cap 27 upward by a so-called toggle mechanism that uses this as a fulcrum. At this time, as is well known, the toggle mechanism generates a pushing force several times the pinching force, so it is possible to push the cap 27 upward with an extremely slight pinching force. Therefore,
On the contrary, the fitting conditions between the mouth portion 25 and the sealing member 30 and the locking conditions between the locking protrusion 26 and the locking pawl 34 are increased to greatly increase the fitting force between the cap 27 and the container 21, thereby preventing the contents from entering. Even if it is desired to strictly prevent overflow, the cap 27 can be removed relatively easily. The cap 27 is moved upward by the above-mentioned pushing up force, but since the locking pawl 34 moves upward while slidingly contacting the neck portion 24, the cap 27 does not pop out. In addition, when removing this cap 27, bending piece 3 for removing and removing the cap
1 protrudes from the outer cylinder 28 and is further provided with a horizontal knurled groove, so that the bent portion 31a of the bent piece 31 can be pressed without hesitation, and the cap 27 can be removed smoothly. It can also be done. Also, if the cap 27 is made of polypropylene, which has excellent bending fatigue resistance,
Each hinge portion of the bent piece 31 is highly durable and can withstand being attached and detached many times.

As explained above, the cap of this idea is
An outer cylinder having a dogleg-shaped bent piece for attaching and detaching the cap that is brought into contact with the shoulder of the container during opening operation, and an outer cylinder arranged with a gap inside the outer cylinder and formed at the neck of the container. It is constructed by integrally providing an inner cylinder having a locking pawl that engages with a locking protrusion, and a sealing member located inside the inner cylinder and surrounding the container mouth. Since the cap is designed to be attached and detached, the cap can be attached by simply pushing the cap downward, and the cap can be attached and detached by simply pinching the bent part of the folded piece for attaching and detaching the cap. In particular, since a toggle mechanism using a bent piece is used to attach and detach the cap, the cap can be detached with extremely low force.
