Description

ストロー付き飲料容器Beverage container with straw
　本発明は飲料を吸入するためのストローが装着されたストロー付き飲料容器に関する。 The present invention relates to a beverage container with a straw equipped with a straw for inhaling a beverage.
　従来から幼児等を使用者として想定されたストロー付き飲料容器が周知である。このような飲料容器には外部に露出するストローが未使用時に閉塞されるようにストローを折り曲げた状態で隠すことができるストローキャップが設けられている。そのストローキャップが使用時に開かれるとストローの閉塞が解除されるので、容器に収められた飲料をストローを用いて使用者が飲むことができる。 Conventionally, beverage containers with straws that are assumed to be infants and other users are well known. Such a beverage container is provided with a straw cap that can be hidden in a folded state so that the straw exposed to the outside is closed when not in use. When the straw cap is opened during use, the straw is unblocked, so that the user can drink the beverage contained in the container using the straw.
　ところが、外気よりも温度が高い湯等の暖かい飲料が容器に収められている場合には密閉された容器の内圧が高まる。そのため、ストローキャップが開かれると、その開放と同時に閉塞が解除されるストローから飲料が噴出する場合がある。そこで、ストロー付き飲料容器には内圧を外部に逃がすための開閉弁が設けられていることが一般的である。 However, when a warm beverage such as hot water having a temperature higher than the outside air is contained in the container, the internal pressure of the sealed container increases. Therefore, when the straw cap is opened, the beverage may be ejected from the straw that is released from the closing simultaneously with the opening of the straw cap. Therefore, a drinking container with a straw is generally provided with an on-off valve for releasing the internal pressure to the outside.
　例えば、このような開閉弁を備えたストロー付き飲料容器として、ストローキャップを閉状態に保持するロック部材と容器に設けられた空気孔を開閉する開閉弁の弁体とが一体化され、ロック部材の操作によってストローキャップのロックが解除されたときに空気孔が弁体にて開かれることにより内圧を逃がすことができる飲料容器が知られている（特許文献１）。 For example, as a beverage container with a straw provided with such an on-off valve, a lock member that holds a straw cap in a closed state and a valve body of an on-off valve that opens and closes an air hole provided in the container are integrated, and the lock member There is known a beverage container in which an internal pressure can be released by opening an air hole with a valve body when the straw cap is unlocked by the operation (Patent Document 1).
特開２００２－３２１７４１号公報JP 2002-321741 A
　特許文献１の飲料容器は、ストローキャップのロックを解除するロック部材の操作によって内圧を逃がすことができるが、一旦開かれた空気孔を閉じるにはロック部材をストローキャップが開かれた状態で再度操作することが必要になる。つまり、ストローキャップが開かれて飲料を飲むことが可能になった後に空気孔を閉じるためのロック部材の操作を使用者に強いることになる。そのため、ロック部材に対する操作が使用者にとって煩わしいものになるおそれがある。また、ストローキャップが開かれた後に行うべきロック部材の操作を使用者が忘れた場合には空気孔が開かれたままになるので、例えば飲料容器を傾けて使用する際に空気孔からの飲料の漏れを誘発するおそれがある。 In the beverage container of Patent Document 1, the internal pressure can be released by operating the lock member that unlocks the straw cap. To close the air hole that has been once opened, the lock member is again opened with the straw cap opened. It becomes necessary to operate. In other words, the user is forced to operate the lock member for closing the air hole after the straw cap is opened and it becomes possible to drink. Therefore, the operation on the lock member may be troublesome for the user. In addition, when the user forgets to operate the lock member to be performed after the straw cap is opened, the air hole remains open. For example, when the beverage container is tilted, the beverage from the air hole is used. May cause leakage.
　また、特許文献１の飲料容器は、ストローキャップのロック解除により内圧を逃がした後に、ストローキャップが開かれた状態でロック部材を再度操作することにより空気孔を閉じることができる。ところが、夏場のように外気温が高い状況では、ストローキャップが開かれた使用状態で空気孔が閉じられたまま放置されると、容器内の空気が膨張することによってストローから飲料が漏れ出す問題がある。こうした問題を回避するため、特許文献１の飲料容器の場合はストローキャップが開いた状態でロック部材を操作して空気孔を開く操作を行うことが必要である。また、その後、ストローキャップを閉じて使用を止めようとする場合には再度ロック部材を操作して空気孔を閉じる操作が必要となる。このように飲料漏れを起こすことなく特許文献１の飲料容器を使用するには、ロック部材に対する操作が使用者にとって煩わしいものになるおそれがある。 Also, the beverage container of Patent Document 1 can close the air hole by operating the lock member again with the straw cap opened after releasing the internal pressure by unlocking the straw cap. However, when the outside air temperature is high, such as in summer, when the air hole is closed and the straw cap is opened, the beverage leaks from the straw due to the expansion of the air in the container. There is. In order to avoid such a problem, in the case of the beverage container of Patent Document 1, it is necessary to operate the lock member to open the air hole in a state where the straw cap is opened. After that, when the straw cap is closed to stop the use, it is necessary to operate the lock member again to close the air hole. Thus, in order to use the drink container of patent document 1 without raise | generating a drink leak, there exists a possibility that operation with respect to a locking member may become troublesome for a user.
　そこで、本発明は、操作に対する煩わしさを使用者に感じさせることを防止できるストロー付き飲料容器を提供することを目的とする。 Therefore, an object of the present invention is to provide a beverage container with a straw that can prevent the user from feeling troublesome to the operation.
　本発明の第１のストロー付き飲料容器は、開口部を持つ容器本体と、前記開口部を塞ぐようにして前記容器本体に装着されたストローアダプタとを備え、前記容器本体内の飲料を吸入するためのストローが前記ストローアダプタに装着されたストロー付き飲料容器において、前記ストローを隠す閉位置と前記ストローを露出させる開位置との間で動作可能な状態で前記ストローアダプタに取り付けられたストローキャップと、前記ストローキャップを前記閉位置にロックするロック位置と、そのロックを解除する解除位置との間で動作可能なロック部材と、前記容器本体の内外を閉鎖する閉状態と前記容器本体の内外を連通する開状態との間で状態を変更でき、所定操作を受け付けることにより前記閉状態から前記開状態へ移行するとともに、前記所定操作が解除されることにより前記開状態から前記閉状態へ復帰する開閉弁と、前記ロック位置から前記解除位置へ向かう前記ロック部材の動作を前記開閉弁に対する前記所定操作として伝達し、かつ前記ストローキャップが前記開位置に位置した状態で前記開閉弁に対する前記所定操作が解除されるように前記開閉弁から離間する伝達部材と、を備えるものである。 A first beverage container with a straw according to the present invention comprises a container body having an opening, and a straw adapter attached to the container body so as to close the opening, and inhales a beverage in the container body. A straw cap attached to the straw adapter in a state operable between a closed position for concealing the straw and an open position for exposing the straw, in a beverage container with a straw attached to the straw adapter. A lock member operable between a lock position for locking the straw cap in the closed position and a release position for releasing the lock; a closed state for closing the inside and outside of the container body; and an inside and outside of the container body The state can be changed between the open state and the open state, and when the predetermined operation is accepted, the closed state is shifted to the open state. An on-off valve that returns from the open state to the closed state when the predetermined operation is released, and an operation of the lock member that is directed from the lock position to the release position is transmitted as the predetermined operation on the on-off valve, And a transmission member spaced from the on-off valve so that the predetermined operation on the on-off valve is released in a state where the straw cap is located at the open position.
　この飲料容器によれば、ロック部材のロック位置から解除位置へ向かう動作によって開閉弁が閉状態から開状態へ移行し、かつストローキャップが開位置に位置した状態で所定操作が解除されるので開閉弁が開状態から閉状態へ復帰する。そのため、ストローキャップに対するロックの解除により内圧を逃がすことができるとともに、ストローキャップが開かれた後には開閉弁が自動的に閉状態になる。従って、ストローキャップを開く際に使用者が特に意識せずに内圧を逃がすことができ、しかもストローキャップが開かれた後にロック部材に対する操作をしなくても開閉弁を通じた飲料漏れを防止できる。よって、使用時に必要な操作に対する煩わしさを使用者に感じさせることを防止できる。 According to this beverage container, the opening / closing valve shifts from the closed state to the open state by the movement of the lock member from the lock position to the release position, and the predetermined operation is released with the straw cap positioned at the open position. The valve returns from the open state to the closed state. Therefore, the internal pressure can be released by releasing the lock on the straw cap, and the open / close valve is automatically closed after the straw cap is opened. Therefore, when opening the straw cap, the user can relieve the internal pressure without being particularly aware of it, and it is possible to prevent the beverage from leaking through the on-off valve without operating the lock member after the straw cap is opened. Therefore, it is possible to prevent the user from feeling troublesome with respect to an operation required at the time of use.
　開閉弁の構造や材質について格別の制限はない。例えば、前記開閉弁は、前記所定操作としての押し込み操作が前記伝達部材にて行われたときに弾性変形し得る弾性材料にて構成された弁体を有し、前記弁体は、前記押し込み操作による弾性変形によって前記開状態に移行し、かつ前記押し込み操作の解除による弾性変形の解消によって前記開状態から前記閉状態へ復帰するように構成されていてもよい。この態様によれば、複数の部品で開閉弁を構成しなくても、弾性材料で構成された弁体の弾性変形を利用して開状態と閉状態とを変更できるから部品点数を容易に削減できる。 There are no particular restrictions on the structure or material of the on-off valve. For example, the on-off valve has a valve body made of an elastic material that can be elastically deformed when the push-in operation as the predetermined operation is performed by the transmission member, and the valve body includes the push-in operation It may be configured to shift to the open state by elastic deformation due to and to return from the open state to the closed state by eliminating elastic deformation by releasing the push-in operation. According to this aspect, the number of parts can be easily reduced because the open state and the closed state can be changed using the elastic deformation of the valve body made of an elastic material without forming the on-off valve with a plurality of parts. it can.
　この態様において、前記弁体は、前記容器本体の内外を区画する板部と、前記板部の周囲を保持するとともに前記押し込み操作を受け付け得る筒状の保持部とが一体化されており、前記板部には、前記押し込み操作の操作方向と同方向に延びて板厚方向に貫通するスリットが形成されていてもよい。この場合、弁体に対して外力が加わらない状態ではスリットが閉じられることにより弁体は閉状態に維持される。弁体の保持部に対して押し込み操作が行われるとその押し込み操作に伴って板部が変形する。その板部の変形によってスリットの両端間距離が短くなるのでスリットが開かれて閉状態から開状態へ移行する。こうした押し込み操作が解除された場合、弁体の弾性変形が解消して板部及び保持部の両者が元の状態に戻るのでスリットが閉じられて閉状態に復帰できる。 In this aspect, the valve body is integrated with a plate portion that divides the inside and outside of the container body, and a cylindrical holding portion that holds the periphery of the plate portion and can receive the pushing operation, The plate portion may be formed with a slit extending in the same direction as the operation direction of the pushing operation and penetrating in the plate thickness direction. In this case, when no external force is applied to the valve body, the valve body is kept closed by closing the slit. When the pushing operation is performed on the holding portion of the valve body, the plate portion is deformed along with the pushing operation. Since the distance between both ends of the slit is shortened by the deformation of the plate portion, the slit is opened and the state is changed from the closed state to the open state. When such push-in operation is released, the elastic deformation of the valve body is canceled and both the plate portion and the holding portion are returned to the original state, so that the slit can be closed to return to the closed state.
　この板部の形状は任意であるが、例えば、前記板部は、前記容器本体の内部側に向かって凸となる曲面状に形成されていてもよい。この場合には、板部を境にして容器本体の内部側の圧力が大気圧よりも高い圧力差が生じた場合、弁体にはスリットを密着させる方向に板部を変形させる力が作用する。そのため、内圧が大気圧より高い圧力差が生じた場合には容器本体の内から外に向かう方向の流体の通過が阻止される。従って、弁体が閉状態に保持されていれば容器本体から外部への飲料の漏れを確実に防止できる。一方、板部を境にして容器本体の内部側の圧力が大気圧よりも低い圧力差が生じた場合、つまり内圧が負圧になった場合、弁体にはスリットを開く方向に板部を変形させる力が作用する。そのため、内圧が大気圧力も低い圧力差が生じた場合には容器本体の外から内に向かう方向の流体の通過を許容することができる。従って、ストローによる飲料の吸入に伴って容器本体内の飲料量が減っていく過程で内圧が負圧になることがあるが、その場合でもその負圧の大きさがスリットが開かれる限界を超えれば弁体を介して外気が容器本体内に取り込まれる。そのため、ストローを用いて飲料を吸入する使用者に多大な吸引力が要求されることがないので使用者の負担を軽減できる。 Although the shape of the plate portion is arbitrary, for example, the plate portion may be formed in a curved surface that is convex toward the inside of the container body. In this case, when a pressure difference is generated where the pressure inside the container main body is higher than the atmospheric pressure with the plate portion as a boundary, a force that deforms the plate portion in the direction in which the slit is in close contact with the valve body acts. . Therefore, when a pressure difference in which the internal pressure is higher than the atmospheric pressure occurs, the passage of fluid in the direction from the inside of the container body to the outside is prevented. Therefore, if the valve body is held in the closed state, the leakage of the beverage from the container body to the outside can be surely prevented. On the other hand, when a pressure difference occurs between the plate part and the inner side of the container body that is lower than the atmospheric pressure, that is, when the internal pressure becomes negative, the plate is placed in the direction to open the slit in the valve body. Deformation force is applied. For this reason, when a pressure difference is generated in which the internal pressure is low and the atmospheric pressure is low, the passage of the fluid in the direction from the outside to the inside of the container body can be permitted. Therefore, the internal pressure may become negative in the process of reducing the amount of beverage in the container body as the beverage is inhaled by the straw, but even in this case, the magnitude of the negative pressure exceeds the limit for opening the slit. The outside air is taken into the container body through the valve body. For this reason, a user who inhales a beverage using a straw is not required to have a great suction force, so the burden on the user can be reduced.
　弾性材料で構成された弁体を有する場合、前記ストローは前記弁体と同一材料で構成された吸い口部を有し、前記吸い口部と前記弁体とが一体化されていてもよい。この場合には、ストローキャップが閉じられた際に吸い口部が容易に弾性変形できる。しかもその吸い口部と弁体とが一体化されているので部品点数を削減できる。 In the case of having a valve body made of an elastic material, the straw may have a mouthpiece portion made of the same material as the valve body, and the mouthpiece portion and the valve body may be integrated. In this case, the mouthpiece can be easily elastically deformed when the straw cap is closed. Moreover, since the mouthpiece and the valve body are integrated, the number of parts can be reduced.
　本発明の第１の飲料容器の一態様において、前記ストローキャップは、支持軸を介して回転自在に前記ストローアダプタに取り付けられることにより前記閉位置と前記開位置との間で動作でき、前記ロック部材は、前記ロック位置と前記解除位置との間で動作可能な状態で前記ストローキャップに設けられ、前記伝達部材は、前記ロック部材と一体移動可能な状態で前記ロック部材に設けられていてもよい。この態様によれば、ロック部材をロック位置から解除位置に向かって動作させてからストローキャップを閉位置から開位置へ動作させることにより、ストローキャップととともにロック部材と伝達部材とがストローアダプタから離れる方向に動作する。このため、伝達部材を開閉弁から離間させるために特別な装置を設けなくても、閉位置から開位置へ向かうストローキャップの動作を利用することによって伝達部材を開閉弁から容易に離間させることができる。 In one aspect of the first beverage container of the present invention, the straw cap can be operated between the closed position and the open position by being rotatably attached to the straw adapter via a support shaft, and the lock The member is provided in the straw cap in a state operable between the lock position and the release position, and the transmission member is provided in the lock member in a state of being movable together with the lock member. Good. According to this aspect, by operating the straw member from the lock position toward the release position and then operating the straw cap from the closed position to the open position, the lock member and the transmission member are separated from the straw adapter together with the straw cap. Operate in the direction. Therefore, the transmission member can be easily separated from the on-off valve by using the operation of the straw cap from the closed position to the open position without providing a special device for separating the transmission member from the on-off valve. it can.
　本発明の第２のストロー付き飲料容器は、開口部を持つ容器本体と、前記開口部を塞ぐようにして前記容器本体に装着されたストローアダプタとを備え、前記容器本体内の飲料を吸入するためのストローが前記ストローアダプタに装着されたストロー付き飲料容器において、前記ストローを隠す閉位置と前記ストローを露出させる開位置との間で動作可能な状態で前記ストローアダプタに取り付けられたストローキャップと、押し込み操作が行われたときに弾性変形し得る弾性材料にて構成された弁体を有し、前記弁体が、前記押し込み操作による弾性変形によって前記容器本体の内外を閉鎖する閉状態から前記容器本体の内外を連通する開状態に移行し、かつ前記押し込み操作の解除による弾性変形の解消によって前記開状態から前記閉状態へ復帰するように構成されている開閉弁と、前記弁体に隣接するようにして前記ストローアダプタ又は前記ストローキャップに設けられた係合部と、前記ストローキャップが前記開位置に位置している状態で前記係合部に係合することにより前記弁体に対して前記押し込み操作を行うことができる第１状態と、前記ストローキャップが前記開位置から前記閉位置へ動作する過程で前記ストローキャップに接触して前記係合部との係合が解除されることにより前記押し込み操作を解除できる第２状態との間で変位できる操作部材と、を備えるものである。 A second beverage container with a straw according to the present invention comprises a container body having an opening, and a straw adapter attached to the container body so as to close the opening, and inhales the beverage in the container body. A straw cap attached to the straw adapter in a state operable between a closed position for concealing the straw and an open position for exposing the straw, in a beverage container with a straw attached to the straw adapter. The valve body is made of an elastic material that can be elastically deformed when the pushing operation is performed, and the valve body is closed from the closed state in which the inside and outside of the container body are closed by the elastic deformation by the pushing operation. The closed state is changed from the open state to the open state by communicating with the inside and outside of the container body, and the elastic deformation is eliminated by releasing the pushing operation. An on-off valve configured to return to the state, an engaging portion provided in the straw adapter or the straw cap so as to be adjacent to the valve body, and the straw cap is located in the open position. In the first state in which the pushing operation can be performed on the valve body by engaging with the engaging portion in a state where the straw cap is in the state, and in the process of operating the straw cap from the open position to the closed position, And an operation member that can be displaced between a second state in which the push-in operation can be released by releasing the engagement with the engagement portion by contacting the cap.
　この飲料容器によれば、弁体が弾性材料で構成されているので、複数の部品で開閉弁を構成しなくても、弁体の弾性変形を利用して開状態と閉状態とを変更できるから部品点数を容易に削減できる。また、この飲料容器によれば、ストローキャップが開位置の状態で、操作部材を係合部に係合させることにより、操作部材によって弁体に押し込み操作が加えられる。そのため、操作部材が係合部に係合している限りにおいて弁体は開状態に維持される。従って、ストローキャップが開かれた状態で外気温が上昇した場合でも、容器本体の内外が連通することによって内圧を常時逃がすことができるので、飲料がストローを通じて漏れることを防止できる。そして、ストローキャップを開位置から閉位置へ動作させた場合には、その動作の過程で操作部材と係合部との係合が解除されて弁体に対する押し込み操作が解除されるので、弁体は閉状態に自動的に復帰する。そのため、弁体が開状態のままでストローキャップが閉位置とされることを確実に防止できる。従って、使用者が特に意識しなくても、ストローキャップを閉じるだけで持ち運び時等に弁体を通じて飲料が漏れることを防止できる。このように、使用者に要求される操作機会が従来よりも減るので、操作に対する煩わしさを使用者に感じさせることを防止できる。 According to this beverage container, since the valve body is made of an elastic material, the open state and the closed state can be changed by utilizing the elastic deformation of the valve body without forming an on-off valve with a plurality of parts. Therefore, the number of parts can be easily reduced. Further, according to this beverage container, the operation member is pushed into the valve body by engaging the operating member with the engaging portion while the straw cap is in the open position. Therefore, as long as the operating member is engaged with the engaging portion, the valve body is maintained in the open state. Therefore, even when the outside air temperature rises with the straw cap opened, the internal pressure of the container main body communicates with the inside and outside of the container body so that the internal pressure can be released at all times, thereby preventing the beverage from leaking through the straw. When the straw cap is moved from the open position to the closed position, the engagement between the operating member and the engaging portion is released in the course of the operation, and the pushing operation on the valve body is released. Automatically returns to the closed state. Therefore, it is possible to reliably prevent the straw cap from being in the closed position while the valve body is in the open state. Therefore, even if the user is not particularly conscious, it is possible to prevent the beverage from leaking through the valve body when carrying it by simply closing the straw cap. As described above, since the operation opportunity required for the user is reduced as compared with the conventional case, it is possible to prevent the user from feeling troublesome to the operation.
　操作部材の構造や材質について格別の制限はない。例えば、前記操作部材は前記弁体と同一材料で構成され、前記弁体と前記操作部材とが一体化されていてもよい。この場合には、単一の加工で弁体と操作部材とを形成することが容易であり、しかも部品点数の削減に貢献できるから組立ての手間を軽減できる。 ¡There are no particular restrictions on the structure or material of the operation members. For example, the operation member may be made of the same material as the valve body, and the valve body and the operation member may be integrated. In this case, it is easy to form the valve body and the operation member by a single process, and it is possible to contribute to the reduction of the number of parts, so that it is possible to reduce the labor of assembly.
　本発明の第２の飲料容器の一態様においては、容器本体の上方に突出していて使用者による引き上げを容易にする突出部が前記操作部材に形成されており、前記突出部の引き上げによって前記操作部材が前記係合部に乗り上がることにより前記操作部材が前記係合部に係合されるものであり、かつ前記ストローキャップが前記開位置から前記閉位置へ動作する過程で前記突出部が前記ストローキャップに接触して押し下げられることにより前記操作部材の前記係合部との係合が解除されてもよい。この態様によれば、操作部材を係合部に係合させるために使用者による引き上げを容易にする突出部が、ストローキャップが閉じられた際に操作部材と係合部との係合を解除するための機能を併せ持っている。このため、こうした各機能を実現する構成を別々に用意する場合に比べて部品点数の削減に寄与できる。 In one aspect of the second beverage container of the present invention, a protrusion is formed on the operation member that protrudes above the container body and facilitates lifting by the user, and the operation is performed by lifting the protrusion. The operating member is engaged with the engaging portion when the member rides on the engaging portion, and the protruding portion moves in the process of the straw cap moving from the open position to the closed position. The operation member may be disengaged from the engagement portion by being pressed down in contact with the straw cap. According to this aspect, the protrusion that facilitates the pulling up by the user to engage the operating member with the engaging portion releases the engagement between the operating member and the engaging portion when the straw cap is closed. It also has a function to do. For this reason, it can contribute to the reduction of the number of parts compared with the case where the structure which implement | achieves each such function is prepared separately.
　本発明の第２の飲料容器の一態様において、前記弁体は、前記容器本体の内外を区画する板部と、前記板部の周囲を保持するとともに前記押し込み操作を受け付け得る筒状の保持部とが一体化されており、前記板部には、前記押し込み操作の操作方向と同方向に延びて板厚方向に貫通するスリットが形成されていてもよい。この場合、弁体に対して外力が加わらない状態ではスリットが閉じられることにより弁体は閉状態に維持される。弁体の保持部に対して押し込み操作が行われるとその押し込み操作に伴って板部が変形する。その板部の変形によってスリットの両端間距離が短くなるのでスリットが開かれて閉状態から開状態へ移行する。こうした押し込み操作が解除された場合、弁体の弾性変形が解消して板部及び保持部の両者が元の状態に戻るのでスリットが閉じられて閉状態に復帰できる。 1 aspect of the 2nd drink container of this invention WHEREIN: The said valve body is the cylindrical holding | maintenance part which can receive the said pushing operation while hold | maintaining the periphery of the said board part, and the board part which divides the inside and outside of the said container main body. And a slit extending in the same direction as the operation direction of the pushing operation and penetrating in the plate thickness direction may be formed in the plate portion. In this case, when no external force is applied to the valve body, the valve body is kept closed by closing the slit. When the pushing operation is performed on the holding portion of the valve body, the plate portion is deformed along with the pushing operation. Since the distance between both ends of the slit is shortened by the deformation of the plate portion, the slit is opened and the state is changed from the closed state to the open state. When such push-in operation is released, the elastic deformation of the valve body is canceled and both the plate portion and the holding portion are returned to the original state, so that the slit can be closed to return to the closed state.

　図１は本発明の一形態に係るストロー付き飲料容器の一部を切断して示した側断面図であり、図２は図１に示された飲料容器の平面図である。これらの図に示したように、ストロー付き飲料容器（以下、飲料容器という。）１は、開口部２ａを持ち飲料を保持し得る容器本体２と、開口部２ａを塞ぐようにして容器本体２に装着されたストローアダプタ３とを備えている。容器本体２には使用者が飲料容器１を持ち易くするために所定形状のハンドルＨが一体的に形成されている。容器本体２の上部外周部には雄ねじ４が設けられており、ストローアダプタ３の内周部にはその雄ねじ４に噛み合う雌ねじ５が設けられている。ストローアダプタ３は各ねじ４、５を互いに噛み合わせた状態で容器本体２にねじ込まれることにより容器本体２に装着されている。ストローアダプタ３には容器本体２内に収められた飲料を吸入するためのストロー６が装着されている。ストロー６は、可撓性を有し使用者に咥えられる吸い口部７と、容器本体２内に収まっている本体部８とが互いに連結されることにより構成されている。吸い口部７と本体部８とは互いに異種材料で構成されている。吸い口部７は弾性変形が容易なシリコーン樹脂にて構成されており、それに連結される本体部８はプラスチックで構成されている。 FIG. 1 is a side cross-sectional view showing a part of a beverage container with a straw according to an embodiment of the present invention, and FIG. 2 is a plan view of the beverage container shown in FIG. As shown in these drawings, a beverage container with a straw (hereinafter referred to as a beverage container) 1 includes a container body 2 that has an opening 2a and can hold a beverage, and a container body 2 that closes the opening 2a. And a straw adapter 3 attached to the. The container body 2 is integrally formed with a handle H having a predetermined shape so that the user can easily hold the beverage container 1. A male screw 4 is provided on the upper outer peripheral portion of the container body 2, and a female screw 5 that meshes with the male screw 4 is provided on the inner peripheral portion of the straw adapter 3. The straw adapter 3 is attached to the container body 2 by being screwed into the container body 2 in a state where the screws 4 and 5 are engaged with each other. The straw adapter 3 is equipped with a straw 6 for inhaling a beverage stored in the container body 2. The straw 6 is configured by connecting a mouthpiece 7 that is flexible and can be received by a user, and a main body 8 that is accommodated in the container main body 2. The mouthpiece 7 and the main body 8 are made of different materials. The mouthpiece portion 7 is made of a silicone resin that is easily elastically deformed, and the main body portion 8 connected thereto is made of plastic.
　ストローアダプタ３には、ストロー６を隠す閉位置（図１参照）とストロー６を露出させる開位置（図７参照）との間で動作可能な状態でストローキャップ９が取り付けられている。ストローキャップ９は支持軸１０を介して回転自在にストローアダプタ３に取り付けられることにより閉位置と開位置との間で動作できる。ストローキャップ９には、閉位置において折り曲げられた状態のストロー６を潰して閉塞させるための突起部１１が設けられており、その突起部１１はストローキャップ９が閉位置にあるときにストロー６を潰すことができるように飲料容器１の下方に突出している。 The straw adapter 9 is attached to the straw adapter 3 so as to be operable between a closed position (see FIG. 1) that hides the straw 6 and an open position (see FIG. 7) that exposes the straw 6. The straw cap 9 can be moved between a closed position and an open position by being rotatably attached to the straw adapter 3 via the support shaft 10. The straw cap 9 is provided with a projection 11 for crushing and closing the straw 6 that is bent in the closed position, and the projection 11 holds the straw 6 when the straw cap 9 is in the closed position. It protrudes below the beverage container 1 so that it can be crushed.
　飲料容器１には、ストローキャップ９を閉位置でロックできるようにするためロック機構１５が設けられている。ロック機構１５は、ストローキャップ９を閉位置でロックするロック位置（図１、２）とそのロックを解除する解除位置（図５Ａ、図５Ｂ）との間で動作可能な状態でストローキャップ９に取り付けられたロック部材１６と、そのロック部材１６がロック位置にあるときにロック部材１６とストローアダプタ３とを噛み合わせる拘束部１７（図２）と、ロック部材１６をロック位置側に付勢するリターンばね１８とを備えている。 The beverage container 1 is provided with a lock mechanism 15 so that the straw cap 9 can be locked in the closed position. The lock mechanism 15 is attached to the straw cap 9 in an operable state between a lock position (FIGS. 1 and 2) for locking the straw cap 9 in the closed position and a release position (FIGS. 5A and 5B) for releasing the lock. The attached lock member 16, a restraining portion 17 (FIG. 2) that engages the lock member 16 and the straw adapter 3 when the lock member 16 is in the lock position, and urges the lock member 16 toward the lock position. And a return spring 18.
　ロック部材１６はロック位置から解除位置まで水平方向に（図１の左右方向に）スライド可能である。ロック部材１６はストローキャップ９の上面に形成された開口部９ａから一部が露出しており、その露出した部分には使用者にて操作され得る操作部１９が形成されている。拘束部１７はロック部材１６の動作方向と同方向に延びる溝状に構成されていて、その溝の長さはロック部材１６が解除位置に達したときにロック部材１６とストローアダプタ３との噛み合いが解除される長さを有している（図５Ａ参照）。リターンばね１８はシリコーン樹脂により構成されていて、ロック部材１６が使用者にて解除位置まで操作されて離されるとリターンばね１８の弾性力によりロック部材１６はロック位置まで復帰できる。 The lock member 16 is slidable in the horizontal direction (left and right in FIG. 1) from the lock position to the release position. A part of the lock member 16 is exposed from an opening 9a formed on the upper surface of the straw cap 9, and an operation part 19 that can be operated by the user is formed in the exposed part. The restraining portion 17 is formed in a groove shape extending in the same direction as the operation direction of the lock member 16, and the length of the groove is the engagement between the lock member 16 and the straw adapter 3 when the lock member 16 reaches the release position. Is released (see FIG. 5A). The return spring 18 is made of silicone resin. When the lock member 16 is operated to the release position by the user and released, the lock member 16 can be returned to the lock position by the elastic force of the return spring 18.
　飲料容器１には、内圧を外部に逃がすことができるようにするため、容器本体２の内外を閉鎖する閉状態と、容器本体２の内外を連通する開状態との間で状態を変更できる開閉弁２０が設けられている。開閉弁２０は、弾性変形可能な弾性材料で構成された弁体２１を備えている。弁体２１はストローアダプタ３に形成された貫通孔２２に密着状態でストローアダプタ３に装着されている。飲料容器１においては、弁体２１はストロー６の吸い口部７と同一材料であるシリコーン樹脂で構成され、かつ吸い口部７と一体に構成されている。飲料容器１は吸い口部７と弁体２１とが一体化されているので部品点数の削減に寄与できる。 The beverage container 1 can be opened and closed to change the state between a closed state in which the inside and outside of the container body 2 are closed and an open state in which the inside and outside of the container body 2 are communicated so that the internal pressure can be released to the outside. A valve 20 is provided. The on-off valve 20 includes a valve body 21 made of an elastic material that can be elastically deformed. The valve body 21 is attached to the straw adapter 3 in close contact with a through hole 22 formed in the straw adapter 3. In the beverage container 1, the valve body 21 is made of a silicone resin, which is the same material as the mouthpiece 7 of the straw 6, and is constructed integrally with the mouthpiece 7. The beverage container 1 can contribute to the reduction of the number of parts because the mouthpiece 7 and the valve body 21 are integrated.
　図３Ａ及び図３Ｂは弁体２１を上方から見た状態を拡大して示した説明図であり、図３Ａはその閉状態を、図３Ｂはその開状態をそれぞれ示している。これらの図にも示したように、弁体２１は容器本体２の内外を区画する板部２５と、その板部２５の周囲を保持する筒状の保持部２６とを備えており、板部２５には板厚方向に貫通するスリット２７が形成されている。図３Ａの場合には、弁体２１に対して外力が加わっていないためスリット２７が密着状態で閉じられるので閉状態に維持される。図３Ｂに示すように、弁体２１の保持部２６に対して矢印方向に所定操作である押し込み操作が行われるとその押し込み操作に伴って板部２５が弾性変形する。スリット２７は押し込み操作の操作方向に延びている。このため、板部２５の弾性変形によってスリット２７の両端間距離Ｘが図３Ａの閉状態に比べて短くなるので、スリット２７が図示のように開かれて閉状態から開状態へ移行する。その押し込み操作が解除された場合、弁体２１の弾性変形が解消して板部２５及び保持部２６の両者が元の状態に戻るのでスリット２７が閉じられて図３Ａの閉状態に復帰できる。 FIGS. 3A and 3B are explanatory views showing an enlarged view of the valve body 21 as viewed from above, FIG. 3A showing its closed state, and FIG. 3B showing its open state. As shown also in these drawings, the valve body 21 includes a plate portion 25 that partitions the inside and the outside of the container body 2 and a cylindrical holding portion 26 that holds the periphery of the plate portion 25. 25 is formed with a slit 27 penetrating in the thickness direction. In the case of FIG. 3A, since the external force is not applied with respect to the valve body 21, since the slit 27 is closed in a close contact state, the closed state is maintained. As shown in FIG. 3B, when a pushing operation that is a predetermined operation in the direction of the arrow is performed on the holding portion 26 of the valve body 21, the plate portion 25 is elastically deformed along with the pushing operation. The slit 27 extends in the operation direction of the pushing operation. For this reason, the distance X between both ends of the slit 27 becomes shorter than that in the closed state of FIG. 3A due to the elastic deformation of the plate portion 25, so that the slit 27 is opened as shown in the figure to shift from the closed state to the open state. When the pushing operation is released, the elastic deformation of the valve body 21 is canceled and both the plate part 25 and the holding part 26 return to the original state, so that the slit 27 is closed and the closed state of FIG. 3A can be restored.
　このような開閉弁２０の弁体２１に対する押し込み操作と、上述したロック機構１５のロック部材１６の動作とを連係させるため、図１に示すように、飲料容器１には、ロック部材１６のロック位置から解除位置へ向かう動作を開閉弁２０に対する押し込み操作として開閉弁２０に伝達する伝達部材３０が設けられている。伝達部材３０はロック部材２１と一体に設けられている。つまり伝達部材３０はロック部材１６と一体移動可能である。 In order to link the pushing operation of the on-off valve 20 with respect to the valve body 21 and the operation of the lock member 16 of the lock mechanism 15 described above, the beverage container 1 has a lock of the lock member 16 as shown in FIG. A transmission member 30 is provided for transmitting the operation from the position toward the release position to the on / off valve 20 as a pushing operation on the on / off valve 20. The transmission member 30 is provided integrally with the lock member 21. That is, the transmission member 30 can move integrally with the lock member 16.
　図４Ａ～図６は、図１及び図２の状態からロック部材１６が解除位置側に操作されてからストローキャップ９が開位置側に開かれるまでの飲料容器１の各部の動作を説明している。図４Ａ及び図４Ｂはロック部材１６に対する操作が開始されてからロック部材１６と拘束部１７の噛み合いが解除されるまでの間の状態を示しており、図４Ａはその状態の平面図、図４Ｂはその状態の側断面図である。図５Ａ及び図５Ｂはロック部材１６と拘束部１７との噛み合いが解除された状態を示しており、図５Ａはその状態の平面図、図５Ｂはその状態の側断面図である。図６はストローキャップ９が開位置側に開かれた状態を示した側断面図である。 4A to 6 illustrate the operation of each part of the beverage container 1 from the state of FIGS. 1 and 2 until the straw cap 9 is opened to the open position side after the lock member 16 is operated to the release position side. Yes. 4A and 4B show a state from when the operation on the lock member 16 is started until the engagement between the lock member 16 and the restraining portion 17 is released, and FIG. 4A is a plan view of the state, FIG. FIG. 4 is a side sectional view of the state. 5A and 5B show a state where the engagement between the lock member 16 and the restraining portion 17 is released, FIG. 5A is a plan view of the state, and FIG. 5B is a side sectional view of the state. FIG. 6 is a side sectional view showing a state in which the straw cap 9 is opened to the open position side.
　ロック部材１６に対する操作がなされていない図１及び図２の状態では、伝達部材３０と開閉弁２０（弁体２１）とは離れていて弁体２１が閉状態であり、かつストローキャップ９が閉位置にあってストロー６が閉塞されているため容器本体２は密封されている。この状態から、図４Ａ及び図４Ｂに示すようにロック部材１６の操作が開始されてロック部材１６が解除位置側に少し動くことによって伝達部材３０が弁体２１の保持部２６に突き当たり弁体２１の弾性変形が開始する。つまり、伝達部材３０によって弁体２１に対して押し込み操作が開始されスリット２７が開き始まる。そのため、弁体２１を通じて容器本体２内の空気が矢印方向に流れ始めて飲料容器１の内圧の減少が開始する。 1 and 2 in which the lock member 16 is not operated, the transmission member 30 and the on-off valve 20 (valve body 21) are separated from each other, the valve body 21 is closed, and the straw cap 9 is closed. The container body 2 is sealed because the straw 6 is in the closed position. From this state, as shown in FIGS. 4A and 4B, the operation of the lock member 16 is started and the lock member 16 moves slightly toward the release position, whereby the transmission member 30 hits the holding portion 26 of the valve body 21 and the valve body 21. Elastic deformation starts. That is, the transmission member 30 starts pushing the valve body 21 and the slit 27 starts to open. Therefore, the air in the container body 2 starts to flow in the direction of the arrow through the valve body 21, and the decrease in the internal pressure of the beverage container 1 starts.
　続いて、図５Ａ及び図５Ｂに示すように、ロック部材１６が解除位置まで動作すると、ロック部材１６と拘束部１７との噛み合いが解除されてストローキャップ９のロックが解除される。それと並行して、弁体２１が伝達部材３０によって更に押し込まれて弁体２１の変形が最大となる結果、スリット２７の開き具合も最大となる。それにより、ストロー６が閉鎖された状態で飲料容器１の内圧が完全に逃がされる。図５Ａ及び図５Ｂに示したようにロック部材１６を解除位置に維持されている間はストローキャップ９の拘束が解かれているので、ストローキャップ９を閉位置から開位置側へ動作させることができる。 Subsequently, as shown in FIGS. 5A and 5B, when the lock member 16 moves to the release position, the engagement between the lock member 16 and the restraining portion 17 is released, and the straw cap 9 is unlocked. In parallel with this, the valve element 21 is further pushed by the transmission member 30 and the deformation of the valve element 21 is maximized. As a result, the degree of opening of the slit 27 is also maximized. Thereby, the internal pressure of the beverage container 1 is completely released in the state where the straw 6 is closed. As shown in FIGS. 5A and 5B, the straw cap 9 is released while the lock member 16 is maintained at the release position, so that the straw cap 9 can be moved from the closed position to the open position. it can.
　図６に示すように、ストローキャップ９の開位置側への動作に伴って、ストローキャップ９と一緒に移動する伝達部材３０が弁体２１から離間するので、弁体２１に対して伝達部材３０にて行われていた押し込み操作が解除される。その押し込み操作の解除により弁体２１の弾性変形が解消して元の状態に戻り（図３Ａ参照）、弁体２１は自動的に閉状態に復帰する。そして、ストローキャップ９の開位置側への動作によりストローキャップ９によるストロー６の閉塞が解除されてストロー６の吸い口部７が真っ直ぐに伸びた状態になりストロー６の使用が可能となる。 As shown in FIG. 6, the transmission member 30 that moves together with the straw cap 9 moves away from the valve body 21 as the straw cap 9 moves to the open position side. The push-in operation performed at is canceled. By releasing the pushing operation, the elastic deformation of the valve body 21 is canceled and the original state is restored (see FIG. 3A), and the valve body 21 automatically returns to the closed state. Then, the operation of the straw cap 9 toward the open position releases the closure of the straw 6 by the straw cap 9, so that the suction port portion 7 of the straw 6 is straightened and the straw 6 can be used.
　このように、飲料容器１によれば、使用者がストローキャップ９のロックを解除してからストローキャップ９を開位置側へ開く過程で内圧を確実に逃がすことができる。しかも、ストローキャップ９が開かれてストロー６の使用が可能になった段階では開閉弁２０が自動的に閉状態に復帰しているので、使用者が意識して開閉弁２０に対して格別の操作を行うことなく使用時における開閉弁２０からの飲料漏れを防止できる。従って、使用時に必要な操作に対する煩わしさを使用者に感じさせることを防止できる。また、飲料容器１は、伝達部材３０がストローキャップ９に設けられたロック部材１６と一体移動可能な状態でロック部材１６に設けられているから、弁体２１に対して押し込み操作を行っている最中の伝達部材３０を開閉弁２０（弁体２１）から離間させるために特別な装置を設けなくても閉位置から開位置へ向かうストローキャップ９の動作を利用することにより、伝達部材３０を開閉弁２０から容易に離間させることができる。 Thus, according to the beverage container 1, the internal pressure can be surely released in the process of opening the straw cap 9 to the open position side after the user unlocks the straw cap 9. Moreover, since the opening / closing valve 20 is automatically returned to the closed state when the straw cap 9 is opened and the straw 6 can be used, the user is conscious of the opening / closing valve 20 with a special consideration. Beverage leakage from the on-off valve 20 during use can be prevented without operation. Therefore, it is possible to prevent the user from feeling annoyed with the operation necessary for use. Moreover, since the drink container 1 is provided in the lock member 16 in the state which the transmission member 30 can move integrally with the lock member 16 provided in the straw cap 9, it is pushing operation with respect to the valve body 21. FIG. By utilizing the operation of the straw cap 9 from the closed position to the open position without providing a special device for separating the intermediate transmission member 30 from the on-off valve 20 (valve element 21), the transmission member 30 is It can be easily separated from the on-off valve 20.
　飲料容器１の開閉弁２０は、複数の部品で構成する場合と異なり、弾性材料で構成された単一の弁体２１の弾性変形を利用して開状態と閉状態とを変更できるから部品点数を容易に削減できる。その他にも、開閉弁２０は以下に説明する更なる特徴を有している。 Unlike the case where the on-off valve 20 of the beverage container 1 is constituted by a plurality of parts, the open state and the closed state can be changed using the elastic deformation of a single valve body 21 made of an elastic material. Can be easily reduced. In addition, the on-off valve 20 has further features described below.
　図１及び図６等に示すように、開閉弁２０は、その弁体２１の板部２５が容器本体２の内部側に向かって凸となる曲面状に、より具体的には球面状に形成されている。そのため、板部２５を境にして容器本体２の内部側の圧力が大気圧よりも高い圧力差が生じた場合、弁体２１にはスリット２７を密着させる方向に板部２５を変形させる力が作用する。そのため、このような圧力差が生じた場合には容器本体２の内から外に向かう方向の流体の通過が阻止される。従って、弁体２１が閉状態に保持されていれば容器本体２から外部への飲料の漏れを確実に防止できる。一方、板部２５を境にして容器本体２の内部側の圧力が大気圧よりも低い圧力差が生じた場合、つまり内圧が負圧になった場合、弁体２１にはスリット２７を開く方向に板部２５を変形させる力が作用する。そのため、このような圧力差が生じた場合には容器本体２の外から内に向かう方向の流体の通過を許容することができる。従って、ストロー６による飲料の吸入に伴って容器本体２内の飲料量が減っていく過程で内圧が負圧になることがあるが、その場合でもその負圧の大きさがスリット２７が開かれる限界を超えれば弁体２１を介して外気が容器本体２内に取り込まれる。そのため、ストロー６を用いて飲料を吸入する使用者に多大な吸引力が要求されることがないので使用者の負担を軽減できる。 As shown in FIGS. 1 and 6 and the like, the on-off valve 20 is formed in a curved surface in which the plate portion 25 of the valve body 21 is convex toward the inner side of the container body 2, more specifically in a spherical shape. Has been. Therefore, when the pressure difference in which the pressure inside the container main body 2 is higher than the atmospheric pressure occurs with the plate portion 25 as a boundary, the force that deforms the plate portion 25 in the direction in which the slit 27 is brought into close contact with the valve body 21. Works. Therefore, when such a pressure difference occurs, the passage of fluid in the direction from the inside of the container body 2 to the outside is prevented. Therefore, if the valve body 21 is held in the closed state, the beverage can be reliably prevented from leaking from the container body 2 to the outside. On the other hand, when a pressure difference is generated where the pressure inside the container body 2 is lower than atmospheric pressure with the plate portion 25 as a boundary, that is, when the internal pressure becomes negative, the valve body 21 opens the slit 27. The force which deforms the board part 25 acts on this. Therefore, when such a pressure difference occurs, the passage of fluid in the direction from the outside to the inside of the container body 2 can be permitted. Therefore, the internal pressure may become negative while the amount of beverage in the container body 2 is reduced as the beverage 6 is inhaled by the straw 6, but even in that case, the size of the negative pressure opens the slit 27. If the limit is exceeded, outside air is taken into the container body 2 via the valve body 21. For this reason, the user who inhales the beverage using the straw 6 is not required to have a great suction force, so the burden on the user can be reduced.
　飲料容器１には、夏場等の外気温が高い状況でのストロー６からの飲料漏れを防止するため、ストローキャップ９が開位置に位置している状態で開閉弁２０を開状態に保持させる開状態保持機構４０が設けられている。図７～９は開状態保持機構４０の機能を説明するための説明図である。図７は開状態保持機構４０により開閉弁２０の開状態への保持が解除された状態を示した一部側断面図、図８は開状態保持機構４０により開閉弁２０の開状態が保持された状態を示した一部側断面図、図９は図８に示した状態からストローキャップ９が閉位置に操作された後の状態を示した一部側断面図である。 In the beverage container 1, in order to prevent beverage leakage from the straw 6 in a situation where the outside air temperature is high, such as in summer, the beverage container 1 is opened to hold the on-off valve 20 in the open state with the straw cap 9 positioned at the open position. A state holding mechanism 40 is provided. 7 to 9 are explanatory diagrams for explaining the function of the open state holding mechanism 40. FIG. FIG. 7 is a partial side sectional view showing a state in which the opening / closing valve 20 is released from being held in the open state by the open state holding mechanism 40, and FIG. 8 is a diagram in which the open state holding mechanism 40 holds the opening / closing valve 20 in the open state. FIG. 9 is a partial side sectional view showing a state after the straw cap 9 is operated to the closed position from the state shown in FIG.
　図７に示すように、閉状態保持機構４０は、ストローアダプタ３に設けられた係合部４１と、その係合部４１への係合及びその解除によって弁体２１に対する押し込み操作の実施及びその解除とを切り替え得る操作部材４２とを備えている。係合部４１は弁体２１に隣接するように設けられかつ弁体２１に接近する側に突出するように構成されている。操作部材４２は係合部４１と向かい合う方向に突出するようにして保持部２６の外周に固定されている。操作部材４２は弁体２１と同一の弾性材料で構成され、かつ弁体２１と一体に設けられている。弁体２１と操作部材４２とが一体化されているため、これらを単一の加工で形成することが容易であり、しかも部品点数の削減に貢献できるから組立ての手間を軽減できる。また、操作部材４２には容器本体２の上方に突出し、ストローキャップ９と当接可能な突出部としての当接部４２ａが形成されている。 As shown in FIG. 7, the closed state holding mechanism 40 includes an engaging portion 41 provided in the straw adapter 3, an operation of pushing the valve body 21 by engaging and releasing the engaging portion 41, and the engagement portion 41. And an operation member 42 that can be switched between release and release. The engaging portion 41 is provided so as to be adjacent to the valve body 21 and is configured to protrude to the side approaching the valve body 21. The operation member 42 is fixed to the outer periphery of the holding portion 26 so as to protrude in a direction facing the engaging portion 41. The operation member 42 is made of the same elastic material as the valve body 21 and is provided integrally with the valve body 21. Since the valve body 21 and the operation member 42 are integrated, it is easy to form them by a single process, and it is possible to contribute to a reduction in the number of parts, so that it is possible to reduce the labor of assembly. Further, the operation member 42 is formed with an abutting portion 42 a that protrudes above the container main body 2 and can be brought into contact with the straw cap 9.
　ストローキャップ９が開位置に位置した状態で、使用者が筒状の保持部２６の図７における上方左端部を同図の左方に動かすと、その弾性により操作部材４２が上方に持ち上げられ、操作部材４２は係合部４１に乗り上がることにより係合部４１に係合する（図８）。操作部材４２の基端部が保持部２６の外周に固定されているため、操作部材４２が上方に持ち上げられると保持部２６が傾くように変形する。つまり、操作部材４２が係合部４１に係合することによって、弁体２１に対して押し込み操作が加えられ、かつその操作が維持される。図８の状態が本発明に係る第１状態に相当する。図８から明らかなように、この押し込み操作は上述した伝達部材３０による操作とは逆向きに加えられることになるが、操作部材４２による押し込み操作によってもスリット２７がその操作方向に延びているので、図３Ｂに示した場合と同様にスリット２７が開かれて弁体２１は開状態となる。操作部材４２が係合部４１に係合している限りにおいて弁体２１は開状態に維持されるので、ストローキャップ９が開かれた状態で外気温が上昇した場合でも、容器本体２の内外が連通することによって内圧を常時逃がすことができるので、飲料がストロー６を通じて漏れることを防止できる。 When the user moves the upper left end in FIG. 7 of the cylindrical holding portion 26 to the left in FIG. 7 with the straw cap 9 positioned at the open position, the operation member 42 is lifted upward by its elasticity. The operating member 42 is engaged with the engaging portion 41 by riding on the engaging portion 41 (FIG. 8). Since the base end portion of the operation member 42 is fixed to the outer periphery of the holding portion 26, when the operation member 42 is lifted upward, the holding portion 26 is deformed to be inclined. That is, when the operating member 42 is engaged with the engaging portion 41, a pushing operation is applied to the valve body 21, and the operation is maintained. The state of FIG. 8 corresponds to the first state according to the present invention. As is apparent from FIG. 8, this pushing operation is applied in the opposite direction to the operation by the transmission member 30 described above, but the slit 27 extends in the operation direction by the pushing operation by the operation member 42 as well. Similarly to the case shown in FIG. 3B, the slit 27 is opened and the valve body 21 is opened. As long as the operating member 42 is engaged with the engaging portion 41, the valve body 21 is maintained in the open state. Therefore, even when the outside air temperature rises with the straw cap 9 opened, the inside and outside of the container body 2 Since the internal pressure can be always released by communicating, the beverage can be prevented from leaking through the straw 6.
　弁体２１が開状態に維持されたままでストローキャップ９を開位置から閉位置へ動作すると、図９に示したように操作部材４２に形成された当接部４２ａがストローキャップ９に接触して操作部材４２が下方に押し下げられる。これにより、操作部材４２の係合部４１との係合が解除されるため操作部材４２による押し込み操作が解除される。図９の状態が本発明に係る第２状態に相当する。押し込み操作の解除により弁体２１の弾性変形が解消されて弁体２１が元の状態に戻るので、弁体２１は開状態から閉状態へ復帰し飲料容器１が密封される。即ち、弁体２１が開状態のままでストローキャップ９が閉位置とされることを確実に防止できる。 When the straw cap 9 is moved from the open position to the closed position while the valve body 21 is maintained in the open state, the contact portion 42a formed on the operation member 42 contacts the straw cap 9 as shown in FIG. The operation member 42 is pushed downward. Thereby, since engagement with the engaging part 41 of the operation member 42 is cancelled | released, pushing operation by the operation member 42 is cancelled | released. The state of FIG. 9 corresponds to the second state according to the present invention. Since the elastic deformation of the valve body 21 is canceled by releasing the pushing operation and the valve body 21 returns to the original state, the valve body 21 returns from the open state to the closed state, and the beverage container 1 is sealed. That is, it is possible to reliably prevent the straw cap 9 from being in the closed position while the valve body 21 is in the open state.
　飲料容器１が開状態保持機構４０を備えているため、弁体２１を開状態にしていた後に使用者が特に意識しなくてもストローキャップ９を閉じるだけで持ち運び時等に弁体２１を通じて飲料が漏れることを防止できる。このように、飲料容器１においては、使用者に要求される操作機会が従来よりも減るので、操作に対する煩わしさを使用者に感じさせることを防止できる。なお、開状態保持機構４０は、係合部４１がストローアダプタ３に設けられているが、この係合部４１をストローキャップ９に設けることもできる。即ち、図７の位置と同一位置となるように係合部４１をストローキャップ９に設ければ、その係合部４１に操作部材４２が乗り上げた状態状態でストローキャップ９が閉位置側へ動作することにより係合部４１が下方に回転移動するので、操作部材４２と係合部４１との係合を解除させることができる。 Since the beverage container 1 is provided with the open state holding mechanism 40, the beverage body 1 can be passed through the valve body 21 when carrying it by simply closing the straw cap 9 even if the user is not particularly conscious after the valve body 21 is opened. Can be prevented from leaking. As described above, in the beverage container 1, since the operation opportunity required for the user is reduced as compared with the conventional case, it is possible to prevent the user from feeling troublesome to the operation. In addition, although the engaging part 41 is provided in the straw adapter 3 in the open state holding mechanism 40, this engaging part 41 can also be provided in the straw cap 9. That is, if the engaging portion 41 is provided on the straw cap 9 so as to be in the same position as in FIG. 7, the straw cap 9 moves to the closed position side with the operating member 42 riding on the engaging portion 41. By doing so, the engaging portion 41 rotates downward, so that the engagement between the operation member 42 and the engaging portion 41 can be released.
　本発明は、上記形態に限定されず本発明の要旨の範囲内において種々の形態にて実施できる。上述したロック部材１６はストローキャップ９に設けられていて、その動作として直線的にスライドするものである。また、伝達部材３０はロック部材１６と一体移動可能に設けられている。しかしながら、本発明の飲料容器を実施するにあたっては、ロック部材の設置場所や動作形態、伝達部材の構成等を任意に変更できる。例えば、図１０～１４に示した第１～第５の変形例によって本発明を実施することができる。なお、以下の各変形例の説明において、図１～図９に示した形態と同様の機能を持つ構成については特別の事情がない限り同一の参照符号を図面に付して説明を省略する。 The present invention is not limited to the above embodiment, and can be implemented in various forms within the scope of the gist of the present invention. The locking member 16 described above is provided on the straw cap 9 and slides linearly as its operation. Further, the transmission member 30 is provided so as to be movable together with the lock member 16. However, in implementing the beverage container of the present invention, the installation location and operation mode of the lock member, the configuration of the transmission member, and the like can be arbitrarily changed. For example, the present invention can be implemented by the first to fifth modifications shown in FIGS. In the following description of each modification, the same reference numerals are assigned to the components having the same functions as those shown in FIGS. 1 to 9 unless otherwise specified, and the description thereof is omitted.
　図１０は第１の変形例を模式的に示した説明図である。図示するように、第１の変形例に係る飲料容器１Ａには、ストローキャップ９Ａをロックするためのロック機構１５Ａが設けられており、そのロック機構１５Ａは図示のロック位置と解除位置との間でスライド動作可能な状態でストローアダプタ３Ａに取り付けられたロック部材１６Ａを有している。ロック機構１５Ａは、ロック部材１６Ａがロック位置にあるときに、ロック部材１６Ａとストローキャップ９Ａとを噛み合わせる拘束部１７Ａと、ロック部材１６Ａをロック位置側に付勢するリターンばね１８Ａとを備えている。ロック部材１６Ａにはその下方に突出するように構成された伝達部材３０Ａが一体に設けられている。従って、飲料容器１Ａは、ロック部材１６Ａが矢印方向に動作されて解除位置に達すると、伝達部材３０Ａが開閉弁２０の弁体２１を弾性変形させることができる。そして、ロック部材１６Ａが解除位置まで動作することによって、ストローキャップ９Ａの拘束が解かれるので、ストローキャップ９Ａを開位置の側に動作させることができる。ストローキャップ９Ａが開位置に位置した状態でロック部材１６Ａはリターンばね１８Ａにより図示の位置に戻されるので、伝達部材３０Ａが開閉弁２０から離間する。これにより、開閉弁２０の弁体２１に対する伝達部材３０Ａによる押し込み操作が解除されるため、開閉弁２０は開状態から閉状態へ自動的に復帰できる。 FIG. 10 is an explanatory view schematically showing a first modification. As shown in the figure, the beverage container 1A according to the first modification is provided with a lock mechanism 15A for locking the straw cap 9A, and the lock mechanism 15A is located between the illustrated lock position and the release position. The lock member 16A is attached to the straw adapter 3A in a state in which it can slide. The lock mechanism 15A includes a restraining portion 17A that engages the lock member 16A and the straw cap 9A when the lock member 16A is in the lock position, and a return spring 18A that biases the lock member 16A toward the lock position. Yes. The lock member 16A is integrally provided with a transmission member 30A configured to protrude downward. Therefore, in the beverage container 1 </ b> A, when the lock member 16 </ b> A is moved in the arrow direction and reaches the release position, the transmission member 30 </ b> A can elastically deform the valve body 21 of the on-off valve 20. Then, when the lock member 16A moves to the release position, the restriction of the straw cap 9A is released, so that the straw cap 9A can be moved to the open position side. Since the lock member 16A is returned to the illustrated position by the return spring 18A with the straw cap 9A positioned at the open position, the transmission member 30A is separated from the on-off valve 20. Thereby, since pushing operation by 30 A of transmission members with respect to the valve body 21 of the on-off valve 20 is cancelled | released, the on-off valve 20 can return automatically from an open state to a closed state.
　図１１は第２の変形例を模式的に示した説明図である。図示するように、第２の変形例に係る飲料容器１Ｂには、ストローキャップ９Ｂをロックするためのロック機構１５Ｂが設けられており、そのロック機構１５Ｂは図示のロック位置と解除位置との間で回転動作可能な状態でストローアダプタ３Ｂに取り付けられたロック部材１６Ｂを有している。ロック機構１５Ｂは、ロック部材１６Ｂがロック位置にあるときに、ロック部材１６Ｂとストローキャップ９Ｂとを噛み合わせる拘束部１７Ｂと、ロック部材１６Ｂをロック位置側に付勢するリターンばね１８Ｂとを備えている。ロック部材１６Ｂにはその回転中心部から下方に延びる伝達部材３０Ｂが一体に設けられている。従って、飲料容器１Ｂは、ロック部材１６Ｂが矢印方向に回転して解除位置に達すると、伝達部材３０Ｂが開閉弁２０の弁体２１を弾性変形させることができる。そして、ロック部材１６Ｂが解除位置まで動作することによって、ストローキャップ９Ｂの拘束が解かれるので、ストローキャップ９Ｂを開位置の側に動作させることができる。ストローキャップ９Ｂが開位置に位置した状態でロック部材１６Ｂはリターンばね１８Ｂにより図示の位置に戻されるので、伝達部材３０Ｂが開閉弁２０から離間する。これにより、開閉弁２０の弁体２１に対する伝達部材３０Ｂによる押し込み操作が解除されるため、開閉弁２０は開状態から閉状態へ自動的に復帰できる。 FIG. 11 is an explanatory view schematically showing a second modification. As shown in the figure, the beverage container 1B according to the second modification is provided with a lock mechanism 15B for locking the straw cap 9B, and the lock mechanism 15B is located between the illustrated lock position and the release position. The lock member 16B is attached to the straw adapter 3B so as to be rotatable. The lock mechanism 15B includes a restraining portion 17B that engages the lock member 16B and the straw cap 9B when the lock member 16B is in the lock position, and a return spring 18B that biases the lock member 16B toward the lock position. Yes. The lock member 16B is integrally provided with a transmission member 30B extending downward from the center of rotation. Therefore, in the beverage container 1B, when the lock member 16B rotates in the arrow direction and reaches the release position, the transmission member 30B can elastically deform the valve body 21 of the on-off valve 20. Then, when the lock member 16B moves to the release position, the restriction of the straw cap 9B is released, so that the straw cap 9B can be moved to the open position side. Since the lock member 16B is returned to the illustrated position by the return spring 18B in the state where the straw cap 9B is located at the open position, the transmission member 30B is separated from the on-off valve 20. Thereby, since pushing operation by the transmission member 30B with respect to the valve body 21 of the on-off valve 20 is cancelled | released, the on-off valve 20 can return automatically from an open state to a closed state.
　図１２は第３の変形例を模式的に示した説明図である。図示するように、第３の変形例に係る飲料容器１Ｃには、ストローキャップ９Ｃをロックするためのロック機構１５Ｃが設けられており、そのロック機構１５Ｃは図示のロック位置と解除位置との間で回転動作可能な状態でストローキャップ９Ｃに取り付けられたロック部材１６Ｃを有している。ロック機構１５Ｃは、ロック部材１６Ｃがロック位置にあるときに、ロック部材１６Ｃとストローアダプタ３Ｃとを噛み合わせる拘束部１７Ｃと、ロック部材１６Ｃをロック位置側に付勢するリターンばね１８Ｃとを備えている。ロック部材１６Ｃにはその回転中心部から下方に延びる伝達部材３０Ｃが一体に設けられている。従って、飲料容器１Ｃは、ロック部材１６Ｃが矢印方向に回転して解除位置に達すると、伝達部材３０Ｃが開閉弁２０の弁体２１を弾性変形させることができる。そして、ロック部材１６Ｃが解除位置まで動作することによって、ストローキャップ９Ｃの拘束が解かれるので、ストローキャップ９Ｃを開位置の側に動作させることができる。ストローキャップ９Ｃが開位置に位置した状態でロック部材１６Ｃはリターンばね１８Ｃにより元の位置に戻されるので、伝達部材３０Ｃが開閉弁２０から離間する。これにより、伝達部材３０Ｃによる開閉弁２０の弁体２１に対する押し込み操作が解除されるため、開閉弁２０は開状態から閉状態へ自動的に復帰できる。 FIG. 12 is an explanatory view schematically showing a third modification. As shown in the figure, the beverage container 1C according to the third modification is provided with a lock mechanism 15C for locking the straw cap 9C, and the lock mechanism 15C is located between the lock position and the release position shown in the figure. The lock member 16C is attached to the straw cap 9C so as to be rotatable. The lock mechanism 15C includes a restraining portion 17C that engages the lock member 16C and the straw adapter 3C when the lock member 16C is in the lock position, and a return spring 18C that biases the lock member 16C toward the lock position. Yes. The lock member 16C is integrally provided with a transmission member 30C extending downward from the center of rotation. Therefore, in the beverage container 1C, when the lock member 16C rotates in the arrow direction and reaches the release position, the transmission member 30C can elastically deform the valve body 21 of the on-off valve 20. Then, when the lock member 16C moves to the release position, the restriction of the straw cap 9C is released, so that the straw cap 9C can be moved to the open position side. Since the lock member 16C is returned to the original position by the return spring 18C in a state where the straw cap 9C is located at the open position, the transmission member 30C is separated from the on-off valve 20. Thereby, since pushing operation with respect to the valve body 21 of the on-off valve 20 by the transmission member 30C is cancelled | released, the on-off valve 20 can return automatically from an open state to a closed state.
　図１３は第４の変形例を模式的に示した説明図である。この図には上方から見た状態が示されている。第４の変形例に係る飲料容器１Ｄは、ストローキャップ９Ｄをロックするためのロック機構１５Ｄが設けられており、そのロック機構１５Ｄが持っているロック部材１６Ｄの回転軸線方向が第２及び第３の変形例とは異なっている。即ち、ロック部材１６Ｄは、その回転軸線方向が飲料容器１Ｄの上下方向に設定されていて、図示のロック位置から解除位置まで回転動作可能な状態でストローアダプタ３Ｄに取り付けられている。ロック機構１５Ｄは、ロック部材１６Ｄがロック位置にあるときに、ロック部材１６Ｄとストローキャップ９Ｄとを噛み合わせる拘束部１７Ｄと、ロック部材１６Ｄをロック位置側に付勢するリターンばね１８Ｄとを備えている。ロック部材１６Ｄにはその回転中心部から右方向に延びる伝達部材３０Ｄが一体に設けられている。従って、飲料容器１Ｄは、ロック部材１６Ｄが矢印方向に回転して解除位置に達すると、伝達部材３０Ｄが開閉弁２０の弁体２１を弾性変形させることができる。そして、ロック部材１６Ｄが解除位置まで動作することによって、ストローキャップ９Ｄの拘束が解かれるので、ストローキャップ９Ｄを開位置の側に動作させることができる。ストローキャップ９Ｄが開位置に位置した状態でロック部材１６Ｄはリターンばね１８Ｄにより図示の位置に戻されるので、伝達部材３０Ｄが開閉弁２０から離間する。これにより、伝達部材３０Ｄによる開閉弁２０の弁体２１に対する押し込み操作が解除されるため、開閉弁２０は開状態から閉状態へ自動的に復帰できる。この変形例においては、ロック部材１６Ｄがストローキャップ９Ｄ側に設けられるように更に変更することも可能ある。 FIG. 13 is an explanatory view schematically showing a fourth modification. This figure shows the state seen from above. The beverage container 1D according to the fourth modification is provided with a lock mechanism 15D for locking the straw cap 9D, and the rotation axis direction of the lock member 16D that the lock mechanism 15D has is the second and third. This is different from the modified example. That is, the lock member 16D is attached to the straw adapter 3D in a state in which the rotation axis direction is set in the vertical direction of the beverage container 1D, and the lock member 16D can rotate from the lock position to the release position shown in the drawing. The lock mechanism 15D includes a restraining portion 17D that engages the lock member 16D and the straw cap 9D when the lock member 16D is in the lock position, and a return spring 18D that biases the lock member 16D to the lock position side. Yes. The lock member 16D is integrally provided with a transmission member 30D extending rightward from the center of rotation. Therefore, in the beverage container 1D, when the lock member 16D rotates in the arrow direction and reaches the release position, the transmission member 30D can elastically deform the valve body 21 of the on-off valve 20. Then, when the lock member 16D is moved to the release position, the restriction of the straw cap 9D is released, so that the straw cap 9D can be moved to the open position side. Since the lock member 16D is returned to the illustrated position by the return spring 18D in a state where the straw cap 9D is located at the open position, the transmission member 30D is separated from the on-off valve 20. Thereby, since pushing operation with respect to the valve body 21 of the on-off valve 20 by transmission member 30D is cancelled | released, the on-off valve 20 can return automatically from an open state to a closed state. In this modification, the lock member 16D can be further modified so as to be provided on the straw cap 9D side.
　図１４は第５の変形例を模式的に示した説明図である。図示するように、第５の変形例に係る飲料容器１Ｅには、ストローキャップ９Ｅをロックするためのロック機構１５Ｅが設けられており、そのロック機構１５Ｅは図示のロック位置と解除位置との間でスライド動作可能な状態でストローアダプタ３Ｅに取り付けられたロック部材１６Ｅを有している。ロック機構１５Ｅは、ロック部材１６Ｅがロック位置にあるときに、ロック部材１６Ｅとストローキャップ９Ｅとを噛み合わせる拘束部１７Ｅと、ロック部材１６Ｅをロック位置側に付勢するリターンばね１８Ｅとを備えている。開閉弁２０Ｅは、上記各例とは異なり弁体２１Ｅがストローアダプタ３Ｅから長く延びており、ロック部材１６Ｅと一体移動可能にロック部材１６Ｅに取り付けられている。そして、ストローアダプタ８Ｅには弁体２１Ｅに隣接するようにして上方に突出する伝達部材３０Ｅが設けられている。従って、飲料容器１Ｅは、ロック部材１６Ｅが矢印方向に動作されて解除位置に達すると、ロック部材１６Ｅとともに弁体２１Ｅが移動して伝達部材３０Ｅに突き当たるので、弁体２１Ｅに対する押し込み操作が伝達部材３０Ｅにて加えられ弁体２１Ｅが弾性変形する。そして、ロック部材１６Ｅが解除位置まで動作することによって、ストローキャップ９Ｅの拘束が解かれるので、ストローキャップ９Ｅを開位置の側に動作させることができる。ストローキャップ９Ｅが開位置に位置した状態で、ロック部材１６Ｅはリターンばね１８Ｅにより、又はロック部材１６Ｅがストローキャップ９Ｅとともに上方へ移動さうることにより、伝達部材３０Ｅが開閉弁２０Ｅから離間する。これにより、伝達部材３０Ｅによる弁体２１Ｅに対する押し込み操作が解除されるため、開閉弁２０Ｅは開状態から閉状態へ自動的に復帰できる。 FIG. 14 is an explanatory view schematically showing a fifth modification. As shown in the figure, the beverage container 1E according to the fifth modified example is provided with a lock mechanism 15E for locking the straw cap 9E, and the lock mechanism 15E is located between the illustrated lock position and the release position. It has the lock member 16E attached to the straw adapter 3E in the state which can be slid. The lock mechanism 15E includes a restraining portion 17E that engages the lock member 16E and the straw cap 9E when the lock member 16E is in the lock position, and a return spring 18E that biases the lock member 16E toward the lock position. Yes. Unlike the above examples, the on-off valve 20E has a valve body 21E extending from the straw adapter 3E, and is attached to the lock member 16E so as to be movable together with the lock member 16E. The straw adapter 8E is provided with a transmission member 30E protruding upward so as to be adjacent to the valve body 21E. Accordingly, in the beverage container 1E, when the lock member 16E is moved in the arrow direction and reaches the release position, the valve body 21E moves together with the lock member 16E and hits the transmission member 30E. At 30E, the valve body 21E is elastically deformed. Then, when the lock member 16E moves to the release position, the restriction of the straw cap 9E is released, so that the straw cap 9E can be moved to the open position side. With the straw cap 9E positioned at the open position, the lock member 16E is moved away from the on-off valve 20E by the return spring 18E or by the lock member 16E being able to move upward together with the straw cap 9E. Thereby, since pushing operation with respect to the valve body 21E by the transmission member 30E is cancelled | released, the on-off valve 20E can be automatically returned from an open state to a closed state.
　図１～図９に示した形態及び図１０～図１４に示した各変形例に係る開閉弁は、弾性材料で構成された弁体を有し、その弁体の弾性変形を利用して閉状態と開状態とを変更するものである。しかしながら、図１５に示すような構造の開閉弁により本発明を実施することもできる。図１５は開閉弁の他の形態を示した説明図である。図示の開閉弁５０は、容器本体２の内外を仕切る仕切板５１と、その仕切板５１と密着しながら図の左右方向に移動可能な状態で設けられた移動弁体５２と、移動弁体５２を図示の位置側に付勢するリターンばね５３と、移動弁体５３の移動を規制するストッパ５４とを備えている。仕切板５１の中央には移動弁体５２にて塞がれ得る大きさの貫通孔５１ａが形成されている。また、移動弁体５２には仕切板５１の貫通孔５１ａよりも大きな貫通孔５２ａが形成されている。 The on-off valve according to the embodiments shown in FIGS. 1 to 9 and the modifications shown in FIGS. 10 to 14 has a valve body made of an elastic material, and is closed using the elastic deformation of the valve body. The state and the open state are changed. However, the present invention can also be implemented by an on-off valve having a structure as shown in FIG. FIG. 15 is an explanatory view showing another embodiment of the on-off valve. The illustrated on-off valve 50 includes a partition plate 51 that partitions the inside and the outside of the container body 2, a moving valve body 52 that is provided in a state of being movable in the left-right direction in the drawing while being in close contact with the partition plate 51, and a moving valve body 52 Is provided with a return spring 53 that urges the moving valve body 53 to the position shown in the drawing, and a stopper 54 that restricts the movement of the moving valve body 53. A through hole 51 a having a size that can be blocked by the moving valve body 52 is formed in the center of the partition plate 51. Further, the moving valve body 52 is formed with a through hole 52 a larger than the through hole 51 a of the partition plate 51.
　図示の状態においては、仕切板５１の貫通孔５１ａの位置と移動弁体５２の貫通孔５２ａの位置とが互いにずれていて、仕切板５１の貫通孔５１ａが移動弁体５２にて塞がれている。そのため、開閉弁５０は容器本体２の内外を閉鎖する閉状態となる。図示の状態から、移動弁体５２が矢印方向に押し込み操作されると、各貫通孔５１ａ、５２ａの位置が一致するため容器本体２の内外が連通して閉状態から開状態へ移行する。開状態に移行した状態で移動弁体５２に対する押し込み操作が解除されると、移動弁体５２がリターンばね５３により図示の位置に復帰する。そのため、開閉弁５０は押し込み操作の解除とともに開状態から閉状態に自動的に復帰できる。 In the illustrated state, the position of the through hole 51 a of the partition plate 51 and the position of the through hole 52 a of the moving valve body 52 are shifted from each other, and the through hole 51 a of the partition plate 51 is blocked by the moving valve body 52. ing. Therefore, the on-off valve 50 is in a closed state in which the inside and outside of the container body 2 are closed. When the movable valve body 52 is pushed in the direction of the arrow from the state shown in the figure, the positions of the through holes 51a and 52a coincide with each other so that the inside and outside of the container body 2 communicate with each other and the state shifts from the closed state to the open state. When the pushing operation with respect to the moving valve body 52 is released in the state of shifting to the open state, the moving valve body 52 is returned to the illustrated position by the return spring 53. Therefore, the on-off valve 50 can automatically return from the open state to the closed state when the push-in operation is released.
　上述した図１～図９に示した形態及び図１０～図１４に示した各変形例に係る開閉弁を図１５に示した開閉弁５０に置き換えても、その開閉弁５０に対して各伝達部材にて所定操作である押し込み操作を加えることができる。このため、開閉弁５０を利用した飲料容器は上記形態及び各変形例の飲料容器と同等に機能する。 1 to 9 and the open / close valve according to each modification shown in FIGS. 10 to 14 are replaced with the open / close valve 50 shown in FIG. A pushing operation which is a predetermined operation can be applied to the member. For this reason, the beverage container using the on-off valve 50 functions in the same manner as the beverage containers of the above-described form and each modification.
　開閉弁に加える所定操作は開閉弁の構成に応じて適宜に決まるものである。従って、例えば何らかの部材を引っ張ることにより閉状態から開状態へ移行する開閉弁の場合は引っ張り操作が所定操作に該当する。また、何らかの部材を回転させることにより閉状態から開状態へ移行する開閉弁の場合は回転操作が所定操作に該当する。 The predetermined operation applied to the on-off valve is appropriately determined according to the configuration of the on-off valve. Therefore, for example, in the case of an on-off valve that shifts from a closed state to an open state by pulling some member, the pulling operation corresponds to the predetermined operation. In the case of an on-off valve that shifts from a closed state to an open state by rotating some member, the rotation operation corresponds to a predetermined operation.
　弾性変形を利用して閉状態と開状態との間で状態を変化させることができる弁体を用いる場合には、図示の形態の弁体とは異なる構造の弁体を用いてもよい。また、操作部材が弁体と一体に設けられることは必須ではなく、操作部材が弁体と独立して動作するように、操作部材を弁体と別部品として実施することもできる。 When using a valve body that can change its state between a closed state and an open state using elastic deformation, a valve body having a structure different from that of the illustrated valve body may be used. Further, it is not essential that the operating member is provided integrally with the valve body, and the operating member may be implemented as a separate part from the valve body so that the operating member operates independently of the valve body.
