Description

本発明は、飲料容器の栓体に関するものである。   The present invention relates to a stopper for a beverage container.

従来、飲料用容器において、容器本体内に比較的高い温度の液体が収容されている場合には、容器本体内の内圧が高くなったり、ストロー中に溜まった飲料が外から入ってくる空気に押し出されることにより、開蓋時に内容液がストロー部材を介して外部に飛び出し、衣服等を汚してしまうことがあった。   Conventionally, in a beverage container, when a liquid with a relatively high temperature is contained in the container body, the internal pressure in the container body is increased, or the beverage accumulated in the straw is brought into the air from the outside. As a result of the extrusion, the content liquid sometimes jumps out through the straw member when the lid is opened, and the clothes and the like may be soiled.

このような危険を解消するために、レバーを回動させることにより通気孔を閉、開、閉と操作することにより、内圧開放及びストロー部材内の内容液と空気との置換現象をなくし、ストロー先端からの内容液の飛び散りをなくしたものが知られている(例えば特許文献1)。   In order to eliminate such a risk, by rotating the lever to close, open and close the vent hole, the internal pressure release and the substitution phenomenon between the content liquid and air in the straw member are eliminated, and the straw is removed. A device that eliminates scattering of the content liquid from the tip is known (for example, Patent Document 1).

特開2004−345742号公報JP 2004-345742 A

しかしながら、上記のような飲料用筒部材(以下、ストロー部材という)を備えた飲料用容器は、その形状から開口部が小さいため、内容液を飲むために蓋を開ける際、内部の空気層の圧力を解放しなければ、内圧によって内容液深部まで挿入されているストロー部材から内容液が飛び出すおそれがある。そのため、飲料用容器は一般的にストロー部材の液流路を開放する前に、空気層と連通している通気孔を開放し内圧を下げる工夫がなされている。   However, the beverage container provided with the above-described beverage cylinder member (hereinafter referred to as a straw member) has a small opening due to its shape, and therefore, when the lid is opened to drink the content liquid, If the pressure is not released, the content liquid may jump out of the straw member inserted to the content liquid depth due to the internal pressure. Therefore, the beverage container is generally devised to open the vent hole communicating with the air layer and lower the internal pressure before opening the liquid flow path of the straw member.

さらに飲料用容器の開操作時、液流路を閉状態にしたまま通気孔を開け、内圧を下げた後に通気孔を再び閉じなければ、ストロー部材の液流路内に空気と内容液が残されていた場合、ストロー部材内部に内容液が置換され、ストロー部材の液流路内に元々残されていた内容液が飲み口の開時にストロー部材から飛び出すおそれがある。   Furthermore, when opening the beverage container, air and content liquid remain in the liquid flow path of the straw member if the air flow hole is opened with the liquid flow path closed and the internal pressure is lowered and the air vent is not closed again. If it is, the content liquid is replaced inside the straw member, and the content liquid originally left in the liquid flow path of the straw member may jump out of the straw member when the drinking mouth is opened.

このため、ストローク開口部からの内容物の飛散りをなくすため、ストロー容器開時は、ストロー開口部が閉の状態のまま通気口は閉、開、閉の動作を行い、その後ストロー開口部が開となるような工夫がなされている。   For this reason, in order to eliminate the scattering of the contents from the stroke opening, when the straw container is opened, the vent is closed, opened and closed with the straw opening closed, and then the straw opening is opened. It is designed to be open.

また、ストロー開口部開状態・通気孔閉状態のままでは、容器本体内の内容液を飲む際に、容器本体内の空気層が減圧されることで、内容液を吸出し難いという問題もある。   In addition, there is also a problem that it is difficult to suck out the content liquid by reducing the pressure of the air layer in the container body when drinking the content liquid in the container body with the straw opening in the open state and the vent hole closed state.

そこで、本発明が解決しようとする課題は、係止解除ボタンの作用で通気孔の閉、開、閉の操作を簡便、かつ確実に行え、内容液の飛散を防止することができる飲料用容器の栓体を提供することである。   Therefore, the problem to be solved by the present invention is to provide a beverage container that can easily and reliably close, open, and close the air vent by the action of the unlocking button and prevent the liquid content from scattering. Is to provide a plug body.

In addition, an inclined guide surface 41K is formed on the rear portion of the inner surface 41N of the side plate portion 41 so as to face the center side toward the rear side. When the locking member 8 moves rearward, the elastic locking claw 43 is gradually elastically deformed while being guided by the inclined guide surface 41K, and when the elastic locking claw 43 is detached from the rear edge 41F, the inclined surface 43K is guided by the inclined guide surface 41K, and the locking member 8 can advance smoothly. On the lower surface of the lid 7, left and right lid convex portions 44, 44 that are engaging portions for releasing the latching of the elastic latching claws 43 protrude downward.

また、前記案内枠39の上板部40には、前記板状突起部27を前後から挟む位置に、板状突起部45,45を上向きに突設されている。   Further, on the upper plate portion 40 of the guide frame 39, plate-like projecting portions 45, 45 are provided so as to project upward at a position sandwiching the plate-like projecting portion 27 from the front and rear.

また、係止部8Aが係止受け部10に接触して係止した通常の蓋閉成状態では、蓋凸部44は弾性係止爪43に係合せず、通常の蓋閉成状態では蓋7は水平であり、この通常の蓋閉成状態から蓋7の先端側を押すと、蓋7の先端側が下方に回動し、蓋凸部44に弾性係止爪43が係合し、図9の一点鎖線に示すように、弾性係止爪43を内側に押して後縁41Fから弾性係止爪43が外れ、ばね9Aに押されて係止部材8が前側に移動する。また、通常の蓋閉成状態において、栓体本体11の外周には蓋7の下縁7Fと間隔を置いて、外周段部46が周設されており、これら下縁7Fと外周段部46との間隔分だけ、通常の蓋閉成状態から蓋7を下方の係止部材係止解除の蓋閉成状態まで回動することができる。尚、通常の蓋閉成状態では、係止部8Aは係止受け部10に接触しており、係止部材係止解除の蓋閉成状態では、係止受け部10が下がることにより係止部8Aから係止受け部10が離れる。   Further, in the normal lid closed state in which the locking portion 8A is in contact with and locked to the locking receiving portion 10, the lid convex portion 44 does not engage with the elastic locking claw 43, and in the normal lid closed state, the lid is closed. 7 is horizontal, and when the distal end side of the lid 7 is pushed from this normal lid closed state, the distal end side of the lid 7 is rotated downward, and the elastic locking claw 43 is engaged with the lid convex portion 44. 9, the elastic locking claw 43 is pushed inward to release the elastic locking claw 43 from the rear edge 41 </ b> F, and is pushed by the spring 9 </ b> A to move the locking member 8 to the front side. Further, in the normal lid closed state, an outer peripheral step 46 is provided around the outer periphery of the plug body 11 at a distance from the lower edge 7F of the lid 7, and the lower edge 7F and the outer peripheral step 46 are provided. , The lid 7 can be rotated from the normal lid closed state to the lid closed state in which the lower locking member is unlocked. In the normal lid closed state, the latching portion 8A is in contact with the latch receiving portion 10, and in the lid closed state in which the latching member is unlocked, the latch receiving portion 10 is lowered to lock. The latch receiving portion 10 is separated from the portion 8A.

そして、図3及び図4(係止部材前端位置で蓋ロック・通気孔閉状態)に示すように、前端位置の係止部材8の係止部8Aが係止受け部10に係止して蓋7を閉状態でロックしたときには後側凸部37が通気口31Uを閉塞し、使用者が操作部9を押すと、図5(蓋ロックで通気孔開状態)に示すように、係止部8Aが係止受け部10に係止した蓋7のロック状態で、前側位置から係止部8Aが後方に移動して中央凹部38が通気口31Uの上に来た際に隙間ができ、通気口31Uが開成し、通気口31Uから内圧が開放され、ここから係止部材8が後側に移動すると、図6(蓋ロックの係止部材後方位置で通気孔閉状態)に示すように、係止部8Aが係止受け部10に係止した蓋7のロック状態で、前側凸部36が通気口31Uが閉塞し、通気口31Uが閉塞した後、図7(係止部材後端位置で蓋ロック解除・通気孔閉状態)に示すように、係止部8Aが係止受け部10から外れ、係止部材8は後端位置となり、蓋7を開くことができ、同時に弾性係止爪43が後縁41Fに係合して保持され、係止部材8が位置固定される。尚、係止部材8の前端位置では案内横軸35が案内孔34の後縁に係止し、弾性係止爪43が後縁41Fに係止した位置では、案内横軸35が案内孔34の前縁に係止しているか、或いは、案内横軸35と案内孔34の前縁との間に隙間があってもよく、隙間がある場合は、係止部材8を後側に押すと、隙間分だけ係止部材8が僅かに後方に移動し、案内横軸35が案内孔34の前縁に係止し、この位置が後端位置となる。また、係止部材8の前端位置で案内横軸35が案内孔34の後縁との間に隙間があってよく、この場合は、係止受け部10の後面に係止部8Aの前面が当接する。そして、蓋7を開くと、ストローユニット19の飲み口部19Aがその弾性復元力により立ち上がり、容器本体2内の飲料を吸引することができる。   Then, as shown in FIG. 3 and FIG. 4 (the lid lock and the vent hole closed state at the front end position of the locking member), the locking portion 8A of the locking member 8 at the front end position is locked to the locking receiving portion 10. When the lid 7 is locked in the closed state, the rear convex portion 37 closes the vent 31U, and when the user presses the operating portion 9, as shown in FIG. With the lid 7 locked to the locking receiving portion 10 by the portion 8A, a clearance is created when the locking portion 8A moves rearward from the front position and the central recess 38 comes over the vent 31U. When the vent 31U is opened, the internal pressure is released from the vent 31U, and the locking member 8 moves to the rear side from here, as shown in FIG. 6 (the vent hole is closed at the position behind the locking member of the lid lock). In the locked state of the lid 7 where the locking portion 8A is locked to the locking receiving portion 10, the front convex portion 36 closes the vent 31U and the vent 31U closes, then FIG. The locking portion 8A is disengaged from the locking receiving portion 10, and the locking member 8 is at the rear end position so that the lid 7 can be opened. At the same time, the elastic locking claw 43 is engaged with and held by the rear edge 41F, and the locking member 8 is fixed in position. At the front end position of the locking member 8, the guide horizontal shaft 35 is locked to the rear edge of the guide hole 34, and at the position where the elastic locking claw 43 is locked to the rear edge 41F, the guide horizontal shaft 35 is guided to the guide hole 34. Or there may be a gap between the guide horizontal shaft 35 and the front edge of the guide hole 34. If there is a gap, the locking member 8 is pushed rearward. The locking member 8 is slightly moved backward by the gap, and the guide horizontal shaft 35 is locked to the front edge of the guide hole 34, and this position becomes the rear end position. Further, there may be a gap between the guide horizontal shaft 35 and the rear edge of the guide hole 34 at the front end position of the locking member 8, and in this case, the front surface of the locking portion 8 </ b> A is on the rear surface of the locking receiving portion 10. Abut. When the lid 7 is opened, the drinking mouth portion 19A of the straw unit 19 rises due to its elastic restoring force, and the beverage in the container body 2 can be sucked.

一方、蓋7を閉める時においては、蓋7の前側を押し下げると、蓋凸部44に弾性係止爪43が接触して係合し、弾性係止爪43を内側に押して後縁41Fから弾性係止爪43が外れ、ばね9Aに押されて係止部材8が前側に移動し、係止部8Aが係止受け部10に係止して蓋7がロックされ、通気口31Uが後側凸部37により閉塞され、容器本体2が密閉される。この場合、蓋7の前側を押し下げることにより係止受け部10が下がっているから、この係止受け部10に係止部8Aが確実に係止する。   On the other hand, when the lid 7 is closed, if the front side of the lid 7 is pushed down, the elastic latching claw 43 comes into contact with and engages with the lid convex portion 44, and the elastic latching claw 43 is pushed inward to be elastic from the rear edge 41F. The latching claw 43 is released, and the latching member 8 is moved forward by being pushed by the spring 9A, the latching portion 8A is latched by the latching receiving portion 10, the lid 7 is locked, and the vent 31U is located on the rear side. The container body 2 is sealed by being closed by the convex portion 37. In this case, since the latch receiving portion 10 is lowered by pushing down the front side of the lid 7, the latch portion 8 </ b> A is reliably latched to the latch receiving portion 10.

次に前記構成についてその作用を説明する。容器開口3より飲料(図示せず)を容器本体2に収容した後、容器開口3に栓体本体11を取付ける。   Next, the operation of the above configuration will be described. After a beverage (not shown) is accommodated in the container body 2 from the container opening 3, the stopper body 11 is attached to the container opening 3.

図3に示すように蓋7を閉めている時においては、係止部8Aが係止受け部10に係止されているため、蓋7を開けることはできない。尚、通常の閉成状態で、係止部8Aの係止面8Mと、この係止面8Mが当接する係止受け部10の係止受け面10Mはほぼ水平である。また、係止受け部10の下面は凸状湾曲面10Wになっており、係止部8Aの上面は前側が低くなる傾斜面8Uになっている。   As shown in FIG. 3, when the lid 7 is closed, the locking portion 8A is locked to the locking receiving portion 10, and therefore the lid 7 cannot be opened. In the normal closed state, the locking surface 8M of the locking portion 8A and the locking receiving surface 10M of the locking receiving portion 10 with which the locking surface 8M abuts are substantially horizontal. The lower surface of the latch receiving portion 10 is a convex curved surface 10W, and the upper surface of the latch portion 8A is an inclined surface 8U whose front side is lowered.

そして、この状態では通気孔31の通気口31Uは後側凸部37により閉塞されており、また、容器本体2にお茶や調乳時に湯などが収容された場合や、容器開口3に栓体本体11を取付ける際、閉塞部材15が容器開口3に当接してから潰れるまでの加圧により、容器本体2の内圧が大気圧以上となっても、密封状態で保温することができる。   In this state, the vent 31U of the vent 31 is closed by the rear convex portion 37, and when the container body 2 contains tea or hot water during milk preparation, or when the container opening 3 is plugged. When the main body 11 is attached, even when the internal pressure of the container main body 2 becomes equal to or higher than the atmospheric pressure due to the pressure until the closing member 15 comes into contact with the container opening 3 and is crushed, the heat can be kept sealed.

次に、図4に示すように、操作部9を押すと、係止部材8が後側に向って移動し、まず、移動中、通気口31Uを中央凹部38が通過する間、中央凹部38と通気口31Uの間に隙間が発生し、容器本体2の内部が通気孔31により蓋7の内部と連通して大気開放となる。このため容器本体2の内部は通気孔31を介して大気開放となり、内部は大気圧となるため、ストロー先端からの飲料の飛び出しを防ぐことが出来る。   Next, as shown in FIG. 4, when the operating portion 9 is pushed, the locking member 8 moves toward the rear side. First, during the movement, while the central recess 38 passes through the vent 31U, the central recess 38 is moved. And a vent 31U is formed, and the inside of the container body 2 communicates with the inside of the lid 7 through the vent hole 31 and is opened to the atmosphere. For this reason, since the inside of the container main body 2 is opened to the atmosphere via the vent hole 31 and the inside is at atmospheric pressure, it is possible to prevent the beverage from jumping out from the tip of the straw.

次に、図5に示すように、更に係止部材8が後方に移動すると、通気口31Uが後側凸部37により閉塞される。このため容器本体2の内部は、大気圧を保って再び密閉状態とすることで、もしストロー内部に気泡及び飲料が満たされていた状態でも、蓋開放時にストロー内部の圧力による空気の置換が起きず、ストロー内部の飲料が先端から飛び出す恐れがなく、さらに飲料を飲んでいる最中等に不用意に飲料容器を傾けても、飲料が漏れるおそれがない。   Next, as shown in FIG. 5, when the locking member 8 further moves rearward, the vent 31 </ b> U is closed by the rear convex portion 37. For this reason, the inside of the container body 2 is kept in a sealed state by maintaining the atmospheric pressure, so that even if the air bubbles and the beverage are filled inside the straw, the air is replaced by the pressure inside the straw when the lid is opened. In addition, there is no risk of the beverage inside the straw jumping out from the tip, and there is no risk of the beverage leaking even if the beverage container is tilted carelessly while drinking the beverage.

通気口31Uが後側凸部37により閉塞された後、更に係止部材8が後方に移動すると、後縁41Fに弾性係止爪43が係止し、係止部材8が位置固定され、蓋7を開くことができる。このようにして蓋7を開くと板状突起部27,45,45で押圧されていた飲み口部19Aが弾性力によって立ち上がる。そしてこの飲み口部19Aに口を付けて吸うことで、飲料は筒部材23、連通路28、飲み口部19Aを吸い上げられるようになっている。   After the vent 31U is closed by the rear convex portion 37, when the locking member 8 further moves rearward, the elastic locking claw 43 is locked to the rear edge 41F, the locking member 8 is fixed in position, and the lid 7 can be opened. When the lid 7 is opened in this manner, the drinking mouth portion 19A that has been pressed by the plate-like projection portions 27, 45, 45 rises due to the elastic force. By drinking and sucking the mouth part 19A, the beverage can suck up the cylindrical member 23, the communication path 28, and the mouth part 19A.

このようにして飲料を飲んで使用した後、洗浄するには、容器本体2より栓体本体11を外し、さらに栓体本体11より閉塞部材15とシール部材30を外して洗浄する。また、ストローユニット19を栓体本体11より抜き出し洗浄する。そして、洗浄後においては、栓体本体11に閉塞部材15,シール部材30及びストローユニット19を取付けて使用するものである。   In order to wash after drinking and using the beverage in this way, the plug body 11 is removed from the container body 2, and the closure member 15 and the seal member 30 are removed from the plug body 11 and washed. Further, the straw unit 19 is removed from the plug body 11 and washed. After the cleaning, the closing member 15, the sealing member 30, and the straw unit 19 are attached to the plug body 11 for use.

本実施例では、係止部材8は蓋7に係止して該蓋7を閉成状態で固定する係止部8Aを備え、その係止部材8を栓体本体11に前後方向(水平方向)移動可能に設け、この移動位置に通気孔31を設け、前記係止部材8には移動方向に、通気孔31を閉塞する後側凸部37と、通気孔31を開成する中央凹部38と、通気孔31を閉塞する前側凸部36とを並べて設け、係止部8Aは係止受け部10に係止した状態で、所定範囲前後方向に移動可能に設けられ、係止部8Aが係止受け部10に係止した状態で、係止部材8が後方に移動する間に後側凸部37が通気孔31を閉塞し、中央凹部38が通気孔31を開成し、前側凸部36が通気孔31を閉塞した後、係止受け部10から係止部8Aが離脱するから、蓋7を開くために係止部材8を押して係止部材8を稼動することにより、通気孔31が開いて、容器本体2内の圧力を抜くことができ、ストローからの液体の吹き出しを防止することができ、更に係止部材8が稼動すると、通気孔31が閉まり、この後、係止部材8による蓋係止が解除され、蓋7を開くことができる。一方、蓋7を閉めると、係止部材8に蓋7の蓋凸部44が接触して蓋係止が外れ、蓋7が閉状態で係止部材8が保持され、このように操作部9を押して係止部材8を移動することにより、容器本体2を外部と連通して大気開放した後、再び密閉することができる。   In this embodiment, the locking member 8 includes a locking portion 8A that locks the lid 7 and fixes the lid 7 in a closed state, and the locking member 8 is attached to the plug body 11 in the front-rear direction (horizontal direction). ) It is provided so as to be movable, and a vent hole 31 is provided at this moving position. The locking member 8 has a rear convex portion 37 for closing the vent hole 31 in the moving direction, and a central concave portion 38 for opening the vent hole 31. The front convex portion 36 that closes the vent hole 31 is provided side by side, and the locking portion 8A is provided to be movable in the front-rear direction within a predetermined range while being locked to the locking receiving portion 10, and the locking portion 8A is engaged. While the locking member 8 is locked to the stopper portion 10, the rear convex portion 37 closes the vent hole 31 while the locking member 8 moves rearward, the central concave portion 38 opens the vent hole 31, and the front convex portion 36. After closing the vent hole 31, the locking portion 8 </ b> A is detached from the locking receiving portion 10, so that the locking member 8 is operated by pushing the locking member 8 to open the lid 7. It can be opened to release the pressure in the container body 2, the liquid can be prevented from being blown out from the straw, and when the locking member 8 is further operated, the vent hole 31 is closed. The lid locking by is released, and the lid 7 can be opened. On the other hand, when the lid 7 is closed, the lid convex portion 44 of the lid 7 comes into contact with the latching member 8 and the lid latching is released, and the latching member 8 is held in the closed state. By moving the locking member 8 by pushing, the container main body 2 communicates with the outside and is released to the atmosphere, and then can be sealed again.

以上のように、容器本体2の容器開口3に着脱自在に設けられ、開閉可能な蓋7を軸支した栓体本体11と、蓋7を閉状態に保持および解除するように配置された係止部材8と、栓体本体11に係合され弾性材料で形成された飲み口部材たるストローユニット19と、栓体本体11に着脱自在に設けられ、容器開口3に当接して容器本体2を閉塞する閉塞部材15が設けられ、栓体本体11には貫通孔29が形成されており、係止部材8の稼動範囲に通気孔31を有するシール部材30が配置され、蓋7が閉状態の際に通気孔31が閉状態であり、係止部材8を押し込み、係止が解除される過程において、通気孔31は開放され、更に押し込むことで閉状態となり、その後、蓋7との係止が解除され、更に押し込まれた位置で栓体本体11と係合して保持され、係止部材8の可動により、蓋7が開状態となりストローユニット19の止水が開放されるが、その過程において一時的に通気孔31が開状態となり、内部の圧力を開放でき、また、係止部材8が後方で嵌合固定された後に、蓋7が開くことで、蓋7が通気孔31を閉状態にしてストローユニット19の止水が開放されるため、ストロー内部に置換された内容物の飛び出しを防ぐことができる。   As described above, the plug body 11 that is detachably provided in the container opening 3 of the container body 2 and pivotally supports the lid 7 that can be opened and closed, and the member that is arranged to hold and release the lid 7 in the closed state. A stopper member 8, a straw unit 19 that is engaged with the stopper body 11 and made of an elastic material, and a stopper member 11 are detachably provided on the stopper body 11, and comes into contact with the container opening 3 to attach the container body 2. A closing member 15 for closing is provided, a through hole 29 is formed in the plug body 11, a sealing member 30 having a vent hole 31 is disposed in the operating range of the locking member 8, and the lid 7 is in a closed state. In this process, the vent hole 31 is in the closed state, and in the process of pushing the locking member 8 and releasing the lock, the vent hole 31 is opened and further pressed to be closed, and then locked with the lid 7. Is released and engaged with the plug body 11 at the pushed-in position, and the locking member 8 can be As a result, the lid 7 is opened and the water stop of the straw unit 19 is released. In the process, the vent 31 is temporarily opened, the internal pressure can be released, and the locking member 8 is After the fitting and fixing, the lid 7 is opened, so that the lid 7 closes the vent hole 31 and the water stop of the straw unit 19 is released, so that the contents replaced inside the straw are prevented from jumping out. Can do.

また、蓋7を閉める動作において、通常の閉位置よりも下方まで押し込む操作がされた場合に、蓋7の蓋凸部44が係止部材8の後方の弾性係止爪43に接触し、栓体本体11との保持が解除となり、係止部材8が閉位置に移動する。   Further, in the operation of closing the lid 7, when an operation of pushing down below the normal closed position is performed, the lid convex portion 44 of the lid 7 comes into contact with the elastic latching claw 43 behind the latching member 8, and the plug The holding with the body body 11 is released, and the locking member 8 moves to the closed position.

図12〜図19に示す実施例3では、天部5には係止部材8の稼動範囲に貫通孔51を穿設し、この貫通孔51の下部に筒体52を垂設し、この筒体52の底部52Tの中央に内筒体53を上方に向かって突設し、内筒体53は筒体52と間隔を置いて同心円上に設けられ、その内筒体53の内周面により通気孔54を構成し、この通気孔54を開閉する合成樹脂製の軸部材55を備える。尚、前記底部52Tの下面が弁座52Kである。   In the third embodiment shown in FIGS. 12 to 19, a through hole 51 is formed in the operating range of the locking member 8 in the top portion 5, and a cylindrical body 52 is vertically provided below the through hole 51. An inner cylindrical body 53 projects upward from the center of the bottom 52T of the body 52, and the inner cylindrical body 53 is provided concentrically with a space from the cylindrical body 52. The inner circumferential surface of the inner cylindrical body 53 A vent hole 54 is formed, and a shaft member 55 made of synthetic resin that opens and closes the vent hole 54 is provided. The bottom surface of the bottom 52T is a valve seat 52K.

この軸部材55は、前記通気孔54と間隔を置いて上下する軸本体56と、この軸本体56の下端で通気孔54の下方に設けられ当該通気孔54より径大な円盤状の弁部57とを一体に備え、この弁部57にはシール部材58が外装され、このシール部材58の上面が前記底部52Tの弁座52Kに当接することにより前記通気孔54が閉成される。前記軸本体56の上部には段部56Dが設けられており、この段部56Dの上部に径小部56Kを設け、この径小部56Kは先端側に向かって細くなるように形成されると共に先端は面に形成され、その先端面により前記係止部材8の下縁に面接触状態で摺動する摺動先端部56Sが形成されている。さらに、前記径小部56Kをリング状の弾性部材固定部品59の中央に挿通し、この弾性部材固定部品59を前記段部56Dの上部に位置する嵌合凹溝56Mに嵌合して軸本体56に固定し、その弾性部材固定部品59は前記筒体52の内周面に摺動して上下動きし、このように弾性部材固定部品59が軸部材55のスペーサとなって軸本体56と通気孔54と間に隙間が形成され、また、筒体52の内周面と内筒体53の外周面との間に弾性部材たるコイルスプリング60を配置し、このコイルスプリング60は圧縮バネであって、弾性部材固定部品59を上方に付勢する。   The shaft member 55 includes a shaft main body 56 that moves up and down at a distance from the vent hole 54, and a disc-shaped valve portion that is provided below the vent hole 54 at the lower end of the shaft main body 56 and has a larger diameter than the vent hole 54. The valve portion 57 is provided with a seal member 58, and the upper surface of the seal member 58 comes into contact with the valve seat 52K of the bottom portion 52T to close the vent hole 54. A step portion 56D is provided on the upper portion of the shaft body 56, and a small diameter portion 56K is provided on the upper portion of the step portion 56D. The small diameter portion 56K is formed so as to become narrower toward the tip end side. The front end is formed into a surface, and the front end surface forms a sliding front end portion 56S that slides on the lower edge of the locking member 8 in a surface contact state. Further, the small-diameter portion 56K is inserted into the center of the ring-shaped elastic member fixing component 59, and this elastic member fixing component 59 is fitted into the fitting concave groove 56M located at the upper portion of the step portion 56D. The elastic member fixing part 59 slides on the inner peripheral surface of the cylindrical body 52 and moves up and down. Thus, the elastic member fixing part 59 serves as a spacer of the shaft member 55 and the shaft main body 56. A gap is formed between the vent hole 54, and a coil spring 60, which is an elastic member, is disposed between the inner peripheral surface of the cylindrical body 52 and the outer peripheral surface of the inner cylindrical body 53. The coil spring 60 is a compression spring. Thus, the elastic member fixing component 59 is biased upward.

また、前記軸本体56は、実施例1の通気孔54の位置に設けられており、前記係止部材8の下縁面には、実施例1の中央凹部38の位置に、中央凸部61が設けられ、この中央凸部61の前後には一段高く形成された前側凹部62と後側凹部63が設けられている。中央凸部61は下方に向って幅狭になるように両側に傾斜部61K,61Kを有する。そして、係止部材8が移動の際、径小部56Kに傾斜部61Kが係合することにより、軸部材55がスムーズに昇降する。尚、摺動先端部56Sが中央凸部61の前後の前側凹部62と後側凹部63の位置では、シール部材58が弁座52Kに圧接することにより、摺動先端部56Sと係止部材8の下縁との間に隙間が形成される。   Further, the shaft main body 56 is provided at the position of the vent hole 54 of the first embodiment, and a central convex portion 61 is formed on the lower edge surface of the locking member 8 at the position of the central concave portion 38 of the first embodiment. A front concave portion 62 and a rear concave portion 63 which are formed one step higher than the central convex portion 61 are provided. The central convex portion 61 has inclined portions 61K and 61K on both sides so as to become narrower downward. When the locking member 8 moves, the inclined portion 61K engages with the small diameter portion 56K, so that the shaft member 55 moves up and down smoothly. When the sliding tip 56S is located at the front and rear recesses 62 and 63 at the front and rear of the central protrusion 61, the sealing member 58 is in pressure contact with the valve seat 52K. A gap is formed between the lower edge and the bottom edge.

そして、前記弁座52K,軸部材55,弾性部材固定部品59及びコイルスプリング60により、吸気弁構造64を構成しており、容器本体2の内部と外部の圧力が同一の状態では、コイルスプリング60の付勢により弁部57に設けたシール部材58が弁座52Kに当接して通気孔54が閉まり、容器本体2の内圧が外圧より高くなった場合も、シール部材58が弁座52Kに圧接して通気孔54は閉まり、一方、容器本体2の内圧より外圧が高くなると、その圧力差により弁部57のシール部材58が弁座52Kから離れ、通気孔54が開き、容器本体2の内圧と外圧が同じになると、シール部材58により通気孔54が閉まる。   The valve seat 52K, the shaft member 55, the elastic member fixing component 59, and the coil spring 60 constitute an intake valve structure 64. When the pressure inside and outside the container body 2 is the same, the coil spring 60 Even when the sealing member 58 provided in the valve portion 57 abuts on the valve seat 52K by the biasing and the vent hole 54 is closed and the internal pressure of the container body 2 becomes higher than the external pressure, the sealing member 58 is pressed against the valve seat 52K. Then, the vent hole 54 is closed. On the other hand, when the external pressure becomes higher than the internal pressure of the container body 2, the pressure member causes the seal member 58 of the valve portion 57 to move away from the valve seat 52 </ b> K and the vent hole 54 opens. When the external pressure becomes the same, the vent hole 54 is closed by the seal member 58.

また、係止部8Aが係止受け部10に接触して係止した通常の蓋閉成状態では、図18に示すように、蓋凸部44は弾性係止爪43に係合せず、通常の蓋閉成状態では蓋7は水平であり、この通常の蓋閉成状態から蓋7の先端側を押すと、蓋7の先端側が下方に回動し、蓋凸部44が弾性係止爪43に係合し、弾性係止爪43を内側に押して後縁41Fから弾性係止爪43が外れ、ばね9Aに押されて係止部材8が前側に移動する。また、図17に示すように、通常の蓋閉成状態において、栓体本体11の外周には蓋7の下縁7Fと間隔をおいて、外周段部46が周設されており、これら下縁7Fと外周段部46との間隔分だけ、通常の蓋閉成状態から蓋7を下方の係止部材係止解除の蓋閉成状態まで回動することができる。尚、通常の蓋閉成状態では、係止部8Aは係止受け部10に接触しており、係止部材係止解除の蓋閉成状態では、係止受け部10が下がることにより係止部8Aから係止受け部10が離れる。   Further, in a normal lid closed state in which the locking portion 8A comes into contact with the locking receiving portion 10 and is locked, the lid convex portion 44 does not engage with the elastic locking claw 43 as shown in FIG. When the lid 7 is horizontal, the lid 7 is horizontal. When the front end side of the lid 7 is pushed from the normal lid closed state, the front end side of the lid 7 rotates downward, and the lid convex portion 44 is elastically locked. The elastic locking claw 43 is pushed inward by pushing the elastic locking claw 43 inward, and the elastic locking claw 43 is detached from the rear edge 41F. Further, as shown in FIG. 17, in the normal lid closed state, an outer peripheral step 46 is provided around the outer periphery of the plug body 11 at a distance from the lower edge 7F of the lid 7. The lid 7 can be rotated from the normal lid closed state to the lid closed state in which the lower locking member is unlocked by the distance between the edge 7F and the outer peripheral step 46. In the normal lid closed state, the latching portion 8A is in contact with the latch receiving portion 10, and in the lid closed state in which the latching member is unlocked, the latch receiving portion 10 is lowered to lock. The latch receiving portion 10 is separated from the portion 8A.

次に前記構成についてその作用を説明する。容器開口3より飲料(図示せず)を容器本体2に収容した後、容器開口3に栓体本体11を取付ける。この状態では通気孔54は弁部57により閉塞されており、また容器本体2にお茶や調乳時に湯などが収容された場合や、容器開口3に栓体本体11を取付ける際、閉塞部材15が容器開口3に当接してから潰れるまでの加圧により、容器本体2の内圧が大気圧以上となっても、シール部材58が弁座52Kに当接することで、吸気弁構造64は閉弁状態となっている。この結果容器本体2の内部は密封状態となって保温される。   Next, the operation of the above configuration will be described. After a beverage (not shown) is accommodated in the container body 2 from the container opening 3, the stopper body 11 is attached to the container opening 3. In this state, the vent hole 54 is closed by the valve portion 57, and when the container body 2 contains tea or hot water during milk preparation or when the plug body 11 is attached to the container opening 3, the closing member 15 is closed. Even when the internal pressure of the container main body 2 becomes equal to or higher than the atmospheric pressure due to the pressure from when the container contacts the container opening 3 until it is crushed, the intake valve structure 64 is closed by the seal member 58 contacting the valve seat 52K. It is in a state. As a result, the inside of the container body 2 is kept sealed and kept warm.

そして、図12(係止部材前端位置で蓋ロック・通気孔閉状態)に示すように、前端位置の係止部材8の係止部8Aが係止受け部10に係止して蓋7を閉状態でロックしたときには後側凹部63が軸部材55の位置にあり、シール部材58が弁座52Kに圧接することにより通気孔54が閉塞されており、使用者が操作部9を押すと、図14(蓋ロックで通気孔開状態)に示すように、係止部8Aが係止受け部10に係止した蓋7のロック状態で、前側位置から係止部8Aが後方に移動して中央凸部61がコイルスプリング60の付勢に抗して摺動先端部56Sを押し下げ、これにより通気口31Uからシール部材58が離れて通気孔54が開成し、空気Aが矢印に示すように流れ、気孔54から内圧が開放され、ここから係止部材8が後側に移動すると、図15(蓋ロックの係止部材後方位置で通気孔閉状態)に示すように、係止部8Aが係止受け部10に係止した蓋7のロック状態で、摺動先端部56Sの上に前側凹部62が位置し、シール部材58が弁座52Kに圧接することにより通気孔54が閉塞された後、図16(係止部材後端位置で蓋ロック解除で通気孔閉状態)に示すように、係止部8Aが係止受け部10から外れ、係止部材8は後端位置となり、蓋7を開くことができ、同時に弾性係止爪43が後縁41Fに係合して保持され、係止部材8が位置固定される。尚、係止部材8の前端位置では案内横軸35が案内孔34の後縁に係止し、弾性係止爪43が後縁41Fに係止した位置では、案内横軸35が案内孔34の前縁に係止しているか、或いは、案内横軸35と案内孔34の前縁との間に隙間があってもよく、隙間がある場合は、係止部材8を後側に押すと、隙間分だけ係止部材8が僅かに後方に移動し、案内横軸35が案内孔34の前縁に係止し、この位置が後端位置となる。また、係止部材8の前端位置で案内横軸35が案内孔34の後縁との間に隙間があってよく、この場合は、係止受け部10の後面に係止部8Aの前面が当接する。そして、蓋7を開くと、ストローユニット19の飲み口部19Aがその弾性復元力により立ち上がり、容器本体2内の飲料を吸引することができる。   Then, as shown in FIG. 12 (the lid is locked at the front end position of the locking member and the vent hole is closed), the locking portion 8A of the locking member 8 at the front end position is locked to the locking receiving portion 10 and the lid 7 is moved. When locked in the closed state, the rear concave portion 63 is at the position of the shaft member 55, and the sealing member 58 is pressed against the valve seat 52K to close the vent hole 54. When the user presses the operating portion 9, As shown in FIG. 14 (the vent hole is opened by the lid lock), the locking portion 8A is moved rearward from the front position in the locked state of the lid 7 where the locking portion 8A is locked to the locking receiving portion 10. The central projection 61 pushes down the sliding tip 56S against the bias of the coil spring 60, whereby the sealing member 58 is separated from the vent 31U, the vent 54 is opened, and the air A is indicated by an arrow. When the internal pressure is released from the pores 54 and the locking member 8 moves to the rear side from here, FIG. 15 (the locking portion of the lid lock) As shown in the closed position of the vent hole at the rear of the material), the front recess 62 is positioned on the sliding tip 56S in the locked state of the lid 7 where the locking portion 8A is locked to the locking receiving portion 10. After the vent hole 54 is closed by the pressure contact of the seal member 58 with the valve seat 52K, as shown in FIG. 16 (at the rear end position of the locking member, the vent hole is closed and the vent hole is closed), the locking portion 8A is The latch member 8 is disengaged from the latch receiving portion 10, and the latch member 8 is in the rear end position, and the lid 7 can be opened. At the same time, the elastic latch claw 43 is engaged with and held by the rear edge 41F. Fixed. At the front end position of the locking member 8, the guide horizontal shaft 35 is locked to the rear edge of the guide hole 34, and at the position where the elastic locking claw 43 is locked to the rear edge 41F, the guide horizontal shaft 35 is guided to the guide hole 34. Or there may be a gap between the guide horizontal shaft 35 and the front edge of the guide hole 34. If there is a gap, the locking member 8 is pushed rearward. The locking member 8 is slightly moved backward by the gap, and the guide horizontal shaft 35 is locked to the front edge of the guide hole 34, and this position becomes the rear end position. Further, there may be a gap between the guide horizontal shaft 35 and the rear edge of the guide hole 34 at the front end position of the locking member 8, and in this case, the front surface of the locking portion 8 </ b> A is on the rear surface of the locking receiving portion 10. Abut. When the lid 7 is opened, the drinking mouth portion 19A of the straw unit 19 rises due to its elastic restoring force, and the beverage in the container body 2 can be sucked.

容器本体2内の飲料を吸引して容器本体2の内部の飲料が減少すると、容器本体2の内部が負圧になってしまい、口の吸い上げ力を強くしなければならなくなるが、このように容器本体2の内部が負圧になると、弁部57が負圧側となっている容器本体2の内部側(図中、下側)に引き寄せられて弁座52Kより離れる。このようにして通気孔54が開くと、通気孔54より外気が容器本体2の内部に導入される。この結果、容器本体2の内部は大気圧となる通常の口の吸い上げ力で飲料を飲み続けることができる。   When the beverage in the container body 2 is sucked and the beverage in the container body 2 is reduced, the inside of the container body 2 becomes negative pressure, and the suction force of the mouth must be increased. When the inside of the container main body 2 becomes negative pressure, the valve portion 57 is attracted to the inner side (lower side in the figure) of the container main body 2 on the negative pressure side and is separated from the valve seat 52K. When the vent hole 54 is thus opened, outside air is introduced into the container body 2 through the vent hole 54. As a result, the inside of the container body 2 can continue to drink beverages with a normal mouth suction force that is at atmospheric pressure.

以上のように、栓体本体11には貫通孔51が形成されており、係止部材8の稼動範囲に通気孔54が配置され、蓋7が閉状態の際に通気孔54が閉状態であり、係止部材8を押し込み、係止が解除される過程において、通気孔54は開放され、更に押し込むことで閉状態となり、その後、蓋7との係止が解除され、更に押し込まれた位置で栓体本体11と係合して保持され、蓋7を閉める際に係止部材8と蓋7が接触することにより係止部材8と蓋7をほぼ同時に閉状態となるから、係止部材8の可動により、蓋7が開状態となりストローユニット19の止水が開放されるが、その過程において一時的に通気孔54が開状態となり、内部の圧力を開放でき、また、係止部材8が後方で嵌合固定された後に、蓋7が開くことで、蓋7が通気孔54を閉状態にしてストローユニット19の止水が開放されるため、ストロー内部に置換された内容物の飛び出しを防ぐことができる。   As described above, the through hole 51 is formed in the plug body 11, the vent hole 54 is disposed in the operating range of the locking member 8, and the vent hole 54 is closed when the lid 7 is closed. Yes, in the process of pushing the locking member 8 and releasing the lock, the vent hole 54 is opened, and further closed to enter the closed state, and then the lock with the lid 7 is released and further pushed into the position. Since the locking member 8 and the lid 7 are brought into the closed state almost simultaneously by contacting the locking member 8 and the lid 7 when the lid 7 is closed, the locking member 8 is closed. 8, the lid 7 is opened and the water stop of the straw unit 19 is released. In the process, the vent hole 54 is temporarily opened, the internal pressure can be released, and the locking member 8 can be released. After the lid is fitted and fixed at the rear, the lid 7 is opened, so that the lid 7 closes the vent hole 54 and closes the Since the water stopping of the unit 19 is opened, it can be prevented from jumping out of the contents which is substituted therein straw.

また、蓋7を閉める動作において、通常の閉位置よりも下方まで押し込む操作がされた場合に、蓋7の蓋凸部44が係止部材8の後方の弾性係止爪43に接触し、栓体本体11との保持が解除となり、係止部材8が閉位置に移動する。   Further, in the operation of closing the lid 7, when an operation of pushing down below the normal closed position is performed, the lid convex portion 44 of the lid 7 comes into contact with the elastic latching claw 43 behind the latching member 8, and the plug The holding with the body body 11 is released, and the locking member 8 moves to the closed position.

また、本実施例では、貫通孔51に連通して通気孔54を設け、通気孔54の下部の周囲に弁座52Kを設け、前記通気孔54内に軸部材55を上下動可能に設け、この軸部材55の下部に前記弁座52Kに当接して前記通気孔54の下部を開閉可能な弁部57を設けると共に、前記軸部材55を上方の貫通孔51側に付勢する付勢手段たるコイルスプリング60を設けたから、蓋7を開く前に係止部材8により通気孔54を開くことで、湯や温かいお茶などを収容した容器本体2の内部を排気していったん大気圧状態として再び密封し、そして蓋7を開いた後において飲料を吸い出した状態で容器本体2の内部が負圧になっても、吸気弁構造64によって容器本体2の内部を大気圧に保つことができるものであって、係止部材8により降下して通気孔54を開く軸部材55を用いて、容器本体2の内部と外部の圧力差により開閉する吸気弁構造64を構成することができる。   In the present embodiment, a vent hole 54 is provided in communication with the through hole 51, a valve seat 52K is provided around the lower portion of the vent hole 54, and a shaft member 55 is provided in the vent hole 54 so as to be movable up and down. Provided at the lower part of the shaft member 55 is a valve portion 57 that abuts the valve seat 52K to open and close the lower part of the vent hole 54, and biasing means for biasing the shaft member 55 toward the upper through hole 51 side Since the coil spring 60 is provided, by opening the vent hole 54 with the locking member 8 before opening the lid 7, the inside of the container body 2 containing hot water or warm tea is evacuated to once return to atmospheric pressure. Even if the inside of the container body 2 becomes negative pressure after the lid is opened and the beverage is sucked out, the inside of the container body 2 can be kept at atmospheric pressure by the intake valve structure 64. A container member using a shaft member 55 that is lowered by the locking member 8 to open the vent hole 54. An intake valve structure 64 that opens and closes due to a pressure difference between the inside and the outside of the body 2 can be configured.

以上のように、栓体本体11に吸気弁構造64を設けたから、弾性部材からなる閉塞部材15により止水を行っているが、ストローユニット19から吸引を行った際は、軸部材55が降下することにより密閉が解除され、連続吸引が可能となる。   As described above, since the intake valve structure 64 is provided in the plug body 11, the water is stopped by the closing member 15 made of an elastic member. However, when suction is performed from the straw unit 19, the shaft member 55 is lowered. By doing so, sealing is released and continuous suction becomes possible.

また、実施例上の効果として、係止部材8の前後移動により通気孔54を開閉する軸部材55などを用いて吸気弁構造64を構成したから、部品の共通化を図ることができる。   Further, as an effect of the embodiment, since the intake valve structure 64 is configured by using the shaft member 55 that opens and closes the vent hole 54 by the back-and-forth movement of the locking member 8, the parts can be shared.

以下に、他の実施例について説明する。尚、前記各実施例と同一部分には同一符号を付し、その詳細な説明を省略する。   Other embodiments will be described below. In addition, the same code | symbol is attached | subjected to the same part as each said Example, and the detailed description is abbreviate | omitted.

図20〜図22に示す実施例4では、栓体本体11の貫通孔29に吸気弁構造65を設けている。吸気弁構造65は、容器本体2の内圧が大気圧或いは大気圧以上のときは閉弁状態となり、容器本体2の内圧が負圧になったときに、自動的に開弁して容器本体2の内側に吸気できるようにするものであり、その吸気弁構造65は吸気孔66の下端に形成される弁座67と、この弁座67を開閉可能な逆止弁68を備える。   20 to 22, the intake valve structure 65 is provided in the through hole 29 of the plug body 11. The intake valve structure 65 is closed when the internal pressure of the container body 2 is at or above atmospheric pressure, and automatically opens when the internal pressure of the container body 2 becomes negative. The intake valve structure 65 includes a valve seat 67 formed at the lower end of the intake hole 66, and a check valve 68 capable of opening and closing the valve seat 67.

吸気孔66は前記貫通孔29の周囲で前後方向一側に上下方向に設けられ、実施例では貫通孔29の後側に該貫通孔29と連通して貫通孔29の半径よりも細幅で平面視が細溝状に形成されており、この吸気孔66には先端部66Sが設けられている。そして、吸気孔66の下端周囲の一側下面における先端部66Sを含む吸気孔66の近傍により弁座67が形成される。   The intake hole 66 is provided in the vertical direction on one side in the front-rear direction around the through hole 29. In the embodiment, the intake hole 66 communicates with the through hole 29 on the rear side of the through hole 29 and is narrower than the radius of the through hole 29. The plan view is formed in a narrow groove shape, and the suction hole 66 is provided with a tip portion 66S. Then, a valve seat 67 is formed by the vicinity of the intake hole 66 including the tip portion 66S on the lower surface on one side around the lower end of the intake hole 66.

前記シール部材30には、前記下部30Sを設けずに、逆止弁68が一体的に設けられ、この逆止弁68は鍔状をなし、外周側には外側に向かって次第に薄くなる外周先端部69を有し、その逆止弁68の上面外端は前記吸気孔66の先端部66Sより外側にあって、逆止弁68の上面が前記弁座67に当接し、これにより前記貫通孔29及び吸気孔66が閉塞されている。そして、容器本体2の内部と外部の圧力が同一の状態では、弾性により逆止弁68が弁座67に当接して吸気孔66は閉まり、容器本体2の内圧が外圧より高くなると、逆止弁68が弁座67に圧接して吸気孔66は閉まっており、一方、容器本体2の内圧より外圧が高くなると、その圧力差により逆止弁68が弁座67から離れ、吸気孔66が開き、容器本体2の内圧と外圧が同じになると、逆止弁68が閉まる。   The seal member 30 is integrally provided with a check valve 68 without providing the lower portion 30S. The check valve 68 has a bowl-like shape, and the outer peripheral tip gradually decreases toward the outside on the outer peripheral side. Part 69, and the outer end of the upper surface of the check valve 68 is outside the tip 66S of the intake hole 66, and the upper surface of the check valve 68 abuts on the valve seat 67, whereby the through hole 29 and the intake hole 66 are closed. When the pressure inside and outside the container main body 2 is the same, the check valve 68 abuts against the valve seat 67 due to elasticity and the intake hole 66 closes. When the internal pressure of the container main body 2 becomes higher than the external pressure, the check valve 68 When the valve 68 is pressed against the valve seat 67 and the intake hole 66 is closed, on the other hand, when the external pressure becomes higher than the internal pressure of the container body 2, the check valve 68 is separated from the valve seat 67 due to the pressure difference. When the internal pressure and the external pressure of the container body 2 are the same, the check valve 68 is closed.

次に前記構成についてその作用を説明する。容器開口3より飲料(図示せず)を容器本体2に収容した後、容器開口3に栓体本体11を取付ける。この状態では通気孔31の通気口31Uは後側凸部37により閉塞されており、また、容器本体2にお茶や調乳時に湯などが収容された場合や、容器開口3に栓体本体11を取付ける際、閉塞部材15が容器開口3に当接してから潰れるまでの加圧により、容器本体2の内圧が大気圧以上となっても、逆止弁68が弁座67に当接することで、吸気弁構造65は閉弁状態となっている。この結果容器本体2の内部は密封状態となって保温される。   Next, the operation of the above configuration will be described. After a beverage (not shown) is accommodated in the container body 2 from the container opening 3, the stopper body 11 is attached to the container opening 3. In this state, the vent 31U of the vent 31 is closed by the rear convex portion 37, and when the container body 2 contains tea or hot water at the time of milk preparation or when the container opening 3 has the plug body 11 When mounting, the check valve 68 contacts the valve seat 67 even when the internal pressure of the container main body 2 becomes equal to or higher than the atmospheric pressure due to the pressure from when the closing member 15 contacts the container opening 3 until it is crushed. The intake valve structure 65 is closed. As a result, the inside of the container body 2 is kept sealed and kept warm.

そして、前端位置の係止部材8の係止部8Aが係止受け部10に係止して蓋7を閉状態でロックしたときには吸気孔66Uは後側凸部37により閉塞されており、使用者が操作部9を押すと、係止部8Aが係止受け部10に係止した蓋7のロック状態で、前側位置から係止部8Aが後方に移動して中央凹部38により通気口31Uから内圧が開放され、ここから係止部材8が後側に移動すると、係止部8Aが係止受け部10に係止した蓋7のロック状態で、通気口31Uの上に前側凸部36が位置し、通気口31Uが閉塞された後、係止部8Aが係止受け部10から外れ、係止部材8は後端位置となり、蓋7を開くことができ、同時に弾性係止爪43が後縁41Fに係合して保持され、係止部材8が位置固定される。尚、係止部材8の前端位置では案内横軸35が案内孔34の後縁に係止し、弾性係止爪43が後縁41Fに係止した位置では、案内横軸35が案内孔34の前縁に係止しているか、或いは、案内横軸35と案内孔34の前縁との間に隙間があってもよく、隙間がある場合は、係止部材8を後側に押すと、隙間分だけ係止部材8が僅かに後方に移動し、案内横軸35が案内孔34の前縁に係止し、この位置が後端位置となる。また、係止部材8の前端位置で案内横軸35が案内孔34の後縁との間に隙間があってよく、この場合は、係止受け部10の後面に係止部8Aの前面が当接する。   When the engaging portion 8A of the engaging member 8 at the front end position is engaged with the engaging receiving portion 10 and the lid 7 is locked in the closed state, the intake hole 66U is closed by the rear convex portion 37 and used. When the operator presses the operating portion 9, the locking portion 8A moves backward from the front position in the locked state of the lid 7 locked by the locking portion 8A, and the vent 31U is moved by the central recess 38. When the locking member 8 moves rearward from this, the front convex portion 36 is formed above the vent 31U in the locked state of the lid 7 locked by the locking portion 8A to the locking receiving portion 10. After the vent 31U is closed, the locking portion 8A is disengaged from the locking receiving portion 10, the locking member 8 becomes the rear end position, and the lid 7 can be opened, and at the same time, the elastic locking claw 43 Is engaged with and held by the trailing edge 41F, and the locking member 8 is fixed in position. At the front end position of the locking member 8, the guide horizontal shaft 35 is locked to the rear edge of the guide hole 34, and at the position where the elastic locking claw 43 is locked to the rear edge 41F, the guide horizontal shaft 35 is guided to the guide hole 34. Or there may be a gap between the guide horizontal shaft 35 and the front edge of the guide hole 34. If there is a gap, the locking member 8 is pushed rearward. The locking member 8 is slightly moved backward by the gap, and the guide horizontal shaft 35 is locked to the front edge of the guide hole 34, and this position becomes the rear end position. Further, there may be a gap between the guide horizontal shaft 35 and the rear edge of the guide hole 34 at the front end position of the locking member 8, and in this case, the front surface of the locking portion 8 </ b> A is on the rear surface of the locking receiving portion 10. Abut.

また蓋7を開くと板状突起部27,45,45で押圧されていた飲み口部19Aが弾性力によって立ち上がる。そして、この飲み口部19Aに口を付けて吸うことで、飲料は筒部材23、連通路28、飲み口部19Aを吸い上げられるようになっている。   When the lid 7 is opened, the drinking mouth portion 19A that has been pressed by the plate-like protrusions 27, 45, 45 rises due to the elastic force. Then, by sucking the mouthpiece portion 19A with a mouth, the beverage can suck up the cylindrical member 23, the communication path 28, and the mouthpiece portion 19A.

このようにして容器本体2の内部の飲料が減少すると、容器本体2の内部が負圧になってしまい、口の吸い上げ力を強くしなければならなくなるが、このように容器本体2の内部が負圧になると、逆止弁68が負圧側となっている容器本体2の内部側(図20及び図21中、下側)に引き寄せられて弁座67より離れる。このとき、逆止弁68の外周は変形しやすいように薄肉になっている。このようにして逆止弁68が開くと、吸気孔66より外気が容器本体2の内部に導入される。この結果、容器本体2の内部は大気圧となる通常の口の吸い上げ力で飲料を飲み続けることができる。実施例3の吸気弁構造64ではコイルスプリング60の弾性により止水を実現する力と減圧解除の力をコントロールしなければならないが、本実施例によると減圧解除の力の設計管理が別々にでき容易である。   If the beverage inside the container body 2 decreases in this way, the inside of the container body 2 becomes negative pressure, and the suction force of the mouth must be increased. When the negative pressure is reached, the check valve 68 is attracted to the inner side (the lower side in FIGS. 20 and 21) of the container main body 2 on the negative pressure side and is separated from the valve seat 67. At this time, the outer periphery of the check valve 68 is thin so as to be easily deformed. When the check valve 68 is thus opened, outside air is introduced into the container body 2 through the intake hole 66. As a result, the inside of the container body 2 can continue to drink beverages with a normal mouth suction force that is at atmospheric pressure. In the intake valve structure 64 of the third embodiment, it is necessary to control the force for realizing water stop and the force for releasing the decompression by the elasticity of the coil spring 60. According to this embodiment, the design management of the decompression releasing force can be performed separately. Easy.

本実施例では、貫通孔29の近傍、実施例では貫通孔29と連通して天部5を上下方向に貫通する吸気孔66と、上部30Uと共に天部5を上下方向で挟む共に、吸気孔66の下端周囲の天部5の下面5Dによって形成される弁座67に着脱自在に設けられる断面が略逆裁頭円錐形状の逆止弁48とを備えることで、蓋7を開く前に係止部材8により一時的に通気孔31を開くことで、湯や温かいお茶などを収容した容器本体2の内部を排気していったん大気圧状態として再び密封し、そして蓋7を開いた後において飲料を吸い出した状態で容器本体2の内部が負圧になっても、逆止弁68によって容器本体2の内部を大気圧に保つことができるものであって、弾性材料からなるシール部材30には上下方向の通気孔31、シール部材30の下方への抜け止めを図る径大な上部30U、吸気孔66の下端を開閉すると共にシール部材30の上方への移動を弁座67以外の箇所で阻止できる逆止弁68を設け、このように栓体本体11に吸気弁構造65を設けたから、弾性部材からなる閉塞部材15により止水を行っているが、ストローユニット19から吸引を行った際は、シール部材30の逆止弁68が変形することにより密閉が解除され、連続吸引が可能となる。   In the present embodiment, in the vicinity of the through-hole 29, in the embodiment, the intake hole 66 communicating with the through-hole 29 and penetrating the top portion 5 in the vertical direction, and the top portion 5 together with the upper portion 30U are sandwiched in the vertical direction. The cross section detachably provided on the valve seat 67 formed by the lower surface 5D of the top 5 around the lower end of the 66 is provided with a check valve 48 having a substantially inverted truncated conical shape, so that before the lid 7 is opened. By temporarily opening the vent hole 31 by the stop member 8, the inside of the container body 2 containing hot water, warm tea, etc. is evacuated and once sealed to atmospheric pressure, and the beverage is opened after the lid 7 is opened. Even if the inside of the container main body 2 becomes a negative pressure in the state where the air is sucked out, the inside of the container main body 2 can be maintained at the atmospheric pressure by the check valve 68, and the sealing member 30 made of an elastic material includes Large diameter upper part 3 that prevents the vent hole 31 in the vertical direction and the seal member 30 from coming out downward 0U is provided with a check valve 68 that opens and closes the lower end of the intake hole 66 and prevents the upward movement of the seal member 30 at a place other than the valve seat 67. In this way, the plug body 11 is provided with the intake valve structure 65. Therefore, water is stopped by the closing member 15 made of an elastic member, but when suction is performed from the straw unit 19, the check valve 68 of the seal member 30 is deformed to release the sealing, and continuous suction is performed. It becomes possible.

また、吸気孔66に通気弁たる逆止弁68が装着されているから、弾性部材により止水を行っているが、ストローユニット19から吸引を行った際は、吸気弁構造65が開くことにより密閉が解除され、連続吸引が可能となる。   In addition, since a check valve 68 as a ventilation valve is mounted in the intake hole 66, water is stopped by an elastic member, but when suction is performed from the straw unit 19, the intake valve structure 65 is opened. Sealing is released and continuous suction is possible.

さらに、通気弁たる逆止弁68が減圧時に弾性変形するから、容器本体2内が大気圧より低くなると、通気弁が弾性変形して開き、容器本体2の内部を大気圧に保つことができる。   Further, since the check valve 68 as a vent valve is elastically deformed when the pressure is reduced, the vent valve is elastically deformed and opened when the inside of the container body 2 becomes lower than the atmospheric pressure, and the inside of the container body 2 can be maintained at the atmospheric pressure. .
