2. Description of the Related Art Conventionally, so-called one-touch caps have been known that are operated linearly in the vertical direction relative to a container in order to seal and unseal the opening of the container. As an example of this type of cap,
There is a cap disclosed in Publication No. 4353. This cap has a structure as shown in FIG. That is, a container (bottle) 1 has a shoulder part 2 having a mouth part formed on a tapered surface, a neck part 3 protruding from the center, and a mouth part 4 with a flared outer circumferential part formed on the upper part thereof. It is connected via a stepped part 5 and has an outlet 6 at the tip of the mouth part 4,
Molded from hard synthetic resin, etc.
また、キヤツプ７は、全体が可撓性を有する軟

られた構成となつている。 Further, the cap 7 is entirely molded from a flexible soft synthetic resin, and has a substantially flat top plate portion 8, an outer cylinder 9, and an inner cylinder 10. The outer cylinder 9 hangs down from the periphery of the top plate part 8, and the lower end surface of its lower part 9a is formed into an inclined surface 9b, and the inner cylinder 10 is located inside the inner cylinder 9 and similarly hangs down from the top plate part 8. , slits are bored at equal fractions of the circumference of this to form a large number of elastic leg pieces 1.
0a are arranged in a circular manner, and an inward hook-shaped claw piece 11 is provided at the lower end of each leg piece, and the lower end surface of this claw piece 11 is formed into an inclined surface 11a.
A sealing ring 12 is configured to protrude from the inner surface of the center of the top plate portion 8.

から離脱するようになつている。 Then, when the cap 7 is fitted into the container 1 from above the mouth and pressed, the lower end inclined surface 11a of the elastic leg piece 10a descends while being expanded along the flare 4a on the outer periphery of the mouth. The claw piece 11 is snap-locked and fitted to the expansion step portion 5. On the other hand, as shown by the arrow in Fig. 5, the outer cylinder 9 is
When pressure is applied by pinching relatively strongly with fingertips from both sides, the pressurized portion is deformed into an elliptical shape and its position is raised along the tapered shoulder portion 2. At the same time, each elastic leg piece 10a of the inner cylinder 10 is also slightly deformed in its arranged circular shape, so that the claw piece 11 is forcibly released from the step part 5, and the cap 7 is detached from the mouth part. It's summery.
しかしながら、このようなキヤツプにあつて
は、次のような問題点が残されており、その解決
が望まれていた。
However, the following problems remain with such caps, and solutions to these problems have been desired.
(イ) キヤツプを離脱する際、上述のように外筒９
を摘んで変形させるのであるが、外筒９が平坦
な頂板部８から直交して垂下しているため、外
筒９の変形は第６図に示すように頂板部８と外
筒９との交差部を基点として外筒９の下部のみ

筒９の下部を摘んで変形させる必要があり、外
筒９の上部を摘んだ場合には大きな力が必要と
なる。よつて、キヤツプ離脱のために外筒９を
摘む位置が実質的に限定され、使い勝手が劣る
ことになる。(b) When removing the cap, remove the outer cylinder 9 as described above.
However, since the outer cylinder 9 hangs perpendicularly from the flat top plate part 8, the deformation of the outer cylinder 9 is caused by the contact between the top plate part 8 and the outer cylinder 9 as shown in FIG. Only the lower part of the outer cylinder 9 moves inward from the intersection. Therefore, in order to easily remove the cap with a slight force, it is necessary to pinch the lower part of the outer cylinder 9 to deform it, and if the upper part of the outer cylinder 9 is pinched, a large force is required. Therefore, the position at which the outer tube 9 can be pinched to remove the cap is substantially limited, resulting in poor usability.

FIGS. 1 and 2 show an example of the cap of this invention. In these drawings, the cap 21 is integrally formed of soft synthetic resin such as polyethylene, and the top plate portion 22
, an outer cylinder 23 , and an inner cylinder 24 . The top plate portion 22 has a flat disk shape with a slightly concave central portion, and the peripheral portion thereof is the cap 16.
It curves upward in a convex shape to form a curved portion 25.
The outer cylinder 23 hangs down from the periphery of the curved part 25 of the top plate part 22 so that the curved part extends as it is. This outer cylinder 23 is brought into contact with the shoulder of the container during the opening operation, and has a knurled part 26 formed at the lower part of its outer peripheral surface. Further, an inner cylinder 24 hangs down from the periphery of the flat portion of the top plate portion 22. The inner cylinder 24 is arranged inside the outer cylinder 23 with a radial gap, and has a parallel inner circumferential surface slightly larger than the outer diameter of the neck of the container, and has elastic leg pieces 27 at the bottom thereof. Hook-like claw pieces 28... and slits 29... are formed. In addition, this inner cylinder 24
A plurality of radially fin-shaped guide pieces 30 are formed on the inner circumferential surface of the base at intervals in the circumferential direction. These guide pieces 30 are for guiding the cap 21 along the outer surface of the container mouth in the axial direction of the mouth, and a guide slope 31 is formed at the lower part thereof. Furthermore, a cylindrical sealing ring 32 is formed at the center of the inner surface of the top plate portion 22 . This sealing ring 32 is designed to fit inside the mouth of the container to perform a sealing action, and its outer diameter is slightly larger than the inner diameter of the mouth, and its lower end has an inwardly curved tongue. It is becoming a state.
一方、このようなキヤツプ２１に組み合される

体に結合されている。 On the other hand, as shown in FIG. 3, the container 33 combined with such a cap 21 has a neck portion 35 whose outer circumferential surface is approximately parallel to the upper part of the tapered shoulder portion 34, and a lower portion of the outer circumferential surface of the neck portion 35. It has a ring-shaped locking part 36 formed to protrude radially outward, and a mouth part 37 formed above the neck part 35 with a diameter smaller than that of the neck part 35. A guide portion is formed by taking a radius (R), and a ring-shaped protrusion is formed by making the inner edge of the upper end of the mouth portion 37 protrude upward, and in this example, it is integrally molded from hard synthetic resin. and is integrally connected to the container body 38.

であるため、嵌合操作によつてキヤツプ２１の心
出しが行われる。 Therefore, when the container 33 is sealed with the cap 21 having such a configuration, the cap 21 is moved linearly downward. That is, when the inner cylinder 24 is placed over the neck 35, the hook-shaped claw pieces 28 come into contact with the outer peripheral surface of the neck 35. At this time, since the contact surfaces of the neck portion 35 and the inner cylinder 24 are substantially parallel to the axial (up and down) direction, the cap 21 is centered by the fitting operation.

る作用を行う。 Furthermore, if the cap 21 is slightly misaligned, the guide slope 31 of the guide piece 30 will come into contact with the outer edge of the upper end of the opening 37, and the inner surface of the guide piece 30 will subsequently move around the opening 37. Centering takes place again by contacting the outer surface. and,
The axes of the cap 21 and the container 33 are aligned, and the sealing ring 32 and the opening 37 are in contact with each other.
The sealing ring 32 is lowered by lowering the cap 21.
When they are separated, a tight fit with high sealing performance is achieved. Further, it goes without saying that the hook-like claw piece 28 of the inner cylinder 24 is prevented from coming off when it is fitted into the locking part 36 of the neck part 35. Note that the protrusion of the mouth portion 37 is elastically deformed by the top plate portion 22 of the cap 21 to enhance the sealing effect.

昇するためキヤツプ２１が飛び出すことはない。 On the other hand, when removing the cap 21, the user grasps the outer tube 23 of the cap 21 and pushes it toward the center, as in the conventional example. By this operation, only the pinched portion of the outer cylinder 23 moves inward from the curved part 25 of the top plate, and the entire pressed part of the outer cylinder 23 moves parallel to the pressing direction, as shown in FIG. . Due to this deformation, the lower end surface of the outer cylinder 23 has a tapered shoulder portion 3.
4 and pinching the outer cylinder 23 is converted into a force to remove the cap 21 upward by the action of the "wedge", and this force causes the cap 21 to be removed upwardly.
The whole thing tries to move upwards. At the same time, the inner cylinder 2
4. Hook-shaped claw piece 28 at the tip of each elastic leg piece 27...
... are elastically deformed, the container 33 is disengaged from the locking portion 36, and the cap 21 is released from the container 33 and rises. When the cap 21 is detached and raised, the hook-shaped claw piece 28 slides on the surface of the neck portion 35 and rises, so that the cap 21 does not pop out.
このように、キヤツプ２１の離脱に際しては外

し、容易にキヤツプを取り外すことができる。 In this manner, when the cap 21 is removed, by pinching and pushing the outer cylinder 23, the entire pressed portion of the outer cylinder 23 moves inward due to the spring action of the curved portion 25 of the top plate portion 22. Therefore, even if the upper part of the outer cylinder 23 is pinched, the outer cylinder deforms in the same way when the lower part is pinched, and the cap can be easily removed.
以上説明したように本考案のキヤツプにあつて
は、以下のような効果を有している。
As explained above, the cap of the present invention has the following effects.
頂板部の外筒と内筒とをつなぐ部分が湾曲し

圧部分全体が内方に移動する。このため、外筒
上部を摘んでも微かな力でキヤツプの離脱が行
え、外筒のどの部分を摘んでも容易にキヤツプ
を取り外すことができ、使い勝手が向上する。 The part of the top plate that connects the outer cylinder and the inner cylinder is curved, so when the outer cylinder is pinched and pressed, this curved part easily deforms in the radial direction due to the spring action, but does not deform in the vertical direction. , the entire pressing portion of the outer cylinder moves inward. Therefore, even if the upper part of the outer cylinder is pinched, the cap can be removed with a slight force, and the cap can be easily removed by pinching any part of the outer cylinder, improving usability.
また、外筒の押圧部分全体が内方に移動する
ため、押圧力が効率よくキヤツプを引き抜く力
に変換することができ、内筒と容器首部との係
止力を大きくして密封性を高めても、軽い力で
キヤツプを取り外すことができる。 In addition, since the entire pressing part of the outer cylinder moves inward, the pressing force can be efficiently converted into force for pulling out the cap, increasing the locking force between the inner cylinder and the container neck, improving sealing performance. The cap can be removed with light force.
