Description

本発明は、飲料用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).

また、液体収容容器の開口部に取付けられた弁が、容器を握る等して変形された場合に開状態となり、内容液を吐出させることができ、容器が無負荷状態であると閉状態となることで、弁の開閉状態を任意にコントロールすることができるとしたものも知られている（例えば特許文献２）。   Further, when the valve attached to the opening of the liquid storage container is deformed by grasping the container or the like, the valve is opened, and the content liquid can be discharged.If the container is in an unloaded state, the valve is closed. Thus, it is also known that the open / close state of the valve can be arbitrarily controlled (for example, Patent Document 2).

さらに、容器本体の上部開口に設けられた栓体本体に、該栓体本体を閉じるように設ける蓋体をヒンジ部を介して回動自在に設け、このヒンジ部の後ろ側にリング状弾性部材の中間部を掛け回してその一側を栓体本体に、他側を蓋体に掛け止めして、蓋体を開く方向に付勢したものも知られている（例えば特許文献３）。   Furthermore, a lid body provided so as to close the stopper body is provided on the stopper body provided in the upper opening of the container body so as to be rotatable via a hinge part, and a ring-shaped elastic member is provided behind the hinge part. There is also known an example in which an intermediate portion is hung, one side is hooked on the plug body, the other side is hooked on the lid body, and the lid body is urged in the opening direction (for example, Patent Document 3).

特開2004-345742号公報JP 2004-345742 A 米国特許第5213236号公報U.S. Pat.No. 5,213,236 特許第4736133号公報Japanese Patent No. 4736133

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、ストロー部材からの内容液の飛散を防止するため、ストロー部材を備えた飲料用容器では、飲み口が閉の状態のまま通気孔は閉、開、閉の動作を行い、その後にストロー部材の液流路が開となるように工夫がなされているものがあるが、これも通気孔の閉、開、閉の動作が速すぎると十分に内圧が開放されないおそれがある。   For this reason, in order to prevent the content liquid from splashing from the straw member, in a beverage container equipped with a straw member, the vent is closed, opened, and closed with the drinking mouth closed, and then the straw is closed. Some devices have been devised to open the liquid flow path of the member. However, if the operation of closing, opening, and closing the vent hole is too fast, the internal pressure may not be sufficiently released.

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.

ここで、本実施例では、蓋体14を開蓋する前に通気弁34を開弁して内容器５内の空気を大気に逃がしてやるために、図１に示した蓋閉状態において、天部35と通気弁操作用突起部54の下端54Ａとの上下方向の隙間長さ、すなわち係止解除ボタン16側と通気弁34側との上下方向の隙間をＸ、傾斜部60と傾斜受け部57との上下方向の隙間長さをＹ、係止状態にある係止受け部57と係止部47の前後方向の重なり長さをＬ、同一傾斜状態の傾斜部60、傾斜受け部57の仰角度をθとしたとき、ほぼＸ＜Ｙ＋Ｌtanθを満たして遅延機構が構成されるようになっている。尚、隙間長さＸ、Ｙは０mmでもよい。これにより、栓体本体７と蓋体14との係止状態を解除する際に、係止状態が解除される前に通気弁34が下がり、容器本体２内の内圧を開放する機構となる。 Here, in this embodiment, before opening the lid body 14, the vent valve 34 is opened to release the air in the inner container 5 to the atmosphere. In the lid closed state shown in FIG. The vertical gap length between the top portion 35 and the lower end 54A of the vent valve operating projection 54, that is, the vertical gap between the unlocking button 16 side and the vent valve 34 side is X, and the inclined portion 60 and the tilt receiver The gap length in the vertical direction with the portion 57 is Y, the overlap length in the front-rear direction of the locking receiving portion 57 and the locking portion 47 in the locked state is L, the inclined portion 60 in the same inclined state, and the inclined receiving portion 57 When the elevation angle is θ, the delay mechanism is configured so as to satisfy approximately X <Y + Ltanθ. The gap lengths X and Y may be 0 mm. As a result, when the locked state of the plug body 7 and the lid body 14 is released, the vent valve 34 is lowered before the locked state is released, thereby providing a mechanism for releasing the internal pressure in the container body 2.

尚、符号62はシリコンゴム、エラストマー樹脂などの弾性材からなるリング状弾性部材であって、蓋体14をヒンジ部13を回転中心として開くように常に付勢すると共に、スライド係止部材15を係止方向に常に付勢する。このためリング状弾性部材を平面視で緊張状態の矩形に配置し、その一側62Ａをヒンジ部13の前側下部に掛け渡し、他側62Ｂをスライド係止部材15の後端15Ｅに設けたフック部に掛け渡し、さらにその中間部62Ｃをヒンジ部13の後ろ側に掛け回すようにしている。   Reference numeral 62 denotes a ring-shaped elastic member made of an elastic material such as silicon rubber or elastomer resin, which always urges the lid body 14 to open with the hinge portion 13 as a rotation center, and the slide locking member 15 Always bias in the locking direction. For this reason, the ring-shaped elastic member is arranged in a tensioned rectangle in plan view, its one side 62A is hung on the front lower part of the hinge portion 13, and the other side 62B is provided on the rear end 15E of the slide locking member 15 The intermediate portion 62C is hung around the rear side of the hinge portion 13 and is hung around the hinge portion 13.

次に上記構成について、その作用を説明する。蓋体14が閉じた係止状態において、通気弁34は第一のバネ部材39の弾性力により上側方向に向かい付勢された状態で保持され、弁棒36下部に取り付けられた止水部材41により通気孔25が閉塞されて気密状態に保たれている。   Next, the effect | action is demonstrated about the said structure. In the locked state in which the lid 14 is closed, the vent valve 34 is held in a state of being biased upward by the elastic force of the first spring member 39, and the water stop member 41 attached to the lower portion of the valve stem 36. As a result, the vent hole 25 is closed and kept airtight.

一方、閉蓋状態において、通気孔25に対応して栓体本体７の中央やや後ろ側に設けられた係止解除ボタン16を下方に向かい押圧していくと、係止状態が解除される前に、下側に向かって延びる係止解除ボタン16の棒状突起部54により通気弁34が押され、止水部材41が通気弁34と連動して下がることで、通気孔25が開状態となり、容器本体２内の内圧が通気孔25を通って蓋体14の大気と連通する隙間より開放される。   On the other hand, when the lock release button 16 provided in the center of the plug body 7 slightly behind the plug body 7 in the closed state is pressed downward, the lock state is released. In addition, the vent valve 34 is pushed by the rod-like protrusion 54 of the unlocking button 16 extending downward, and the water stop member 41 is lowered in conjunction with the vent valve 34, so that the vent hole 25 is opened, The internal pressure in the container body 2 is released from a gap communicating with the atmosphere of the lid body 14 through the vent hole 25.

そして、係止解除ボタン16を押圧すると、図２に示すように棒状突起部54を介して天部35通気弁34が下方に押圧され、この結果第一のバネ部材39、第二のバネ部材61の弾性力に抗して通気弁34が下降して弁座33より直ちに離れ開弁する。この開弁により、図３に示すように内容器５の内側と大気とは、弁座33と通気弁34との隙間、弁座33と弁棒36との隙間、通気孔25と天部35との隙間、蓋体14の大気と連通する隙間とを介して空気連通路Ａにより連通状態となる。   When the lock release button 16 is pressed, the top 35 vent valve 34 is pressed downward via the rod-shaped protrusion 54 as shown in FIG. 2, and as a result, the first spring member 39 and the second spring member The ventilation valve 34 descends against the elastic force of 61 and immediately leaves the valve seat 33 and opens. By opening the valve, as shown in FIG. 3, the inner side of the inner container 5 and the atmosphere are the gap between the valve seat 33 and the vent valve 34, the gap between the valve seat 33 and the valve stem 36, the vent hole 25 and the top portion 35. The air communication path A establishes a communication state through the gap between the air passage A and the gap of the lid body 14 communicating with the atmosphere.

この第２のバネ部材61がなくても係止解除ボタン16はリング状弾性部材62がスライド係止部材15を付勢している力の分力により、上側の位置になるように付勢されている。 Even if the second spring member 61 is not provided, the lock release button 16 is urged to the upper position by the component force of the force that the ring-shaped elastic member 62 urges the slide lock member 15. ing.

また係止解除ボタン16が押圧されると傾斜部60が傾斜受け部57に接触し、さらに係止解除ボタン16が継続して押圧されると傾斜受け部57、ひいてはスライド係止部材15を前進せしめる。これにより開弁当初より遅れて栓体本体７の係止受部43からスライド係止部材15の係止部56が外れて係止解除となる。係止部56と係止受部43との係止状態が解除されると、蓋体14はＳ字形状に折り曲がっていた飲み口部11が起立する復元力によって持ち上げられて、ヒンジ部13を中心として回動し開蓋する。尚、スライド係止部材15の係止部56が係止受部43から外れる係止解除時と同時に、係止解除ボタン16に対して押圧をやめた場合であっても、係止部56が係止受部43に乗り上げることや飲み口部11が上方に付勢していることにより、スライド係止部材15が係止受部43に再び係止されることもなく開蓋状態となる
。 When the lock release button 16 is pressed, the inclined portion 60 comes into contact with the inclined receiving portion 57, and when the lock release button 16 is continuously pressed, the inclined receiving portion 57 and eventually the slide lock member 15 are advanced. Let me. Accordingly, the locking portion 56 of the slide locking member 15 is released from the locking receiving portion 43 of the plug body 7 with a delay from the beginning of the valve opening, and the locking is released. When the locking state between the locking portion 56 and the locking receiving portion 43 is released, the lid body 14 is lifted by the restoring force of the drinking mouth portion 11 that has been bent into an S shape, and the hinge portion 13 Rotate around and open the lid. Even when the locking portion 56 of the slide locking member 15 is released from the locking receiving portion 43 and at the same time when the locking release button 16 is stopped, the locking portion 56 is engaged. By climbing on the stopper portion 43 and the drinking mouth portion 11 being biased upward, the slide locking member 15 is not locked to the locking receiving portion 43 again, and the lid is opened.

開蓋状態となった後、使用者が係止解除ボタン16から手を離すことにより、係止解除ボタン16が、第二のバネ部材61により弾性復帰して上側に向かい付勢された状態に戻る。また、これに応動して通気弁34が第一のバネ部材39により弾性復帰して、止水部材41により通気孔25が再び閉状態に戻る。こうしたことで、例え使用者が内容液を飲むために吸引した後に液流路31内に空気と内容液が残されていた場合であっても、容器本体２内の内容液が置換されて飛散することが防止される。   After the lid is opened, the user releases the lock release button 16 so that the lock release button 16 is elastically restored by the second spring member 61 and biased upward. Return. In response to this, the vent valve 34 is elastically restored by the first spring member 39, and the vent hole 25 is returned to the closed state by the water stop member 41 again. As a result, even if the user sucks in order to drink the content liquid and the air and the content liquid remain in the liquid flow path 31, the content liquid in the container body 2 is replaced and scattered. Is prevented.

そして、使用後は、開蓋状態の蓋体14を前側に回動し、下側に向けて押圧することで、係止部56が栓体本体７の係止受部43を乗り越えて再び蓋体14を閉蓋状態に係止する。 Then, after use, it rotates the lid 14 of the open lid state to the front, by pressing toward the bottom, again engaging portion 56 gets over the lock receiving portion 43 of the plug body 7 Lid The body 14 is locked in the closed state.

The urging of the locking member 15 in the locking direction can be performed only with the elastic member.

以下に他の実施例について説明する。尚、前記実施例１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 the said Example 1, and the detailed description is abbreviate | omitted.

図７は実施例２を示しており、通気弁34の弁棒36の上部に、実施例１の天部35にかえて円板63をムリ嵌めして固定したものであり、円板63の周縁には、通気孔25の周面とわずかな隙間を有する円筒部64が下向きに設けられている。また、実施例１の止水部材41に代えて通気弁34にはＯリング状の止水部材65が設けられている。   FIG. 7 shows a second embodiment, in which a disk 63 is fixedly fitted to the upper portion of the valve rod 36 of the vent valve 34 in place of the top 35 of the first embodiment. A cylindrical portion 64 having a slight gap with the peripheral surface of the vent hole 25 is provided downward on the periphery. Further, in place of the water stop member 41 of the first embodiment, the vent valve 34 is provided with an O-ring water stop member 65.

したがって、操作部58を押圧すると止水部材65が弁座33に密着した閉弁状態から、円筒部64が通気孔25の周面に案内されながら下降することで開弁することができ、このような実施例においても実施例１と同様な作用効果を奏することができる。   Therefore, when the operation portion 58 is pressed, the cylindrical member 64 can be opened from the closed state in which the water stop member 65 is in close contact with the valve seat 33 while being guided by the peripheral surface of the vent hole 25. In such an embodiment, the same operational effects as those of the first embodiment can be obtained.

さらに飲料を吸い中身が減圧になった時には、バネ部材39が変形することで、開弁することができ、連続吸引が可能となっている。   Furthermore, when the content of sucking the beverage is reduced, the spring member 39 is deformed, so that the valve can be opened and continuous suction is possible.

図８および９は実施例３を示しており、通気弁34に装着される止水部材66はその上部を取付溝40に嵌着すると共に、弁座33の下面42に密着する部位は、上下逆の断面傘形状、すなわち裁頭円錐形状の弁膜部67によって形成されており、この止水部材66はシリコンゴム、エラストマー樹脂等弾性変形する材料によって形成されており、その周縁が下面42に密着する逆止弁形状となっている。   FIGS. 8 and 9 show the third embodiment. The water stop member 66 attached to the vent valve 34 has its upper part fitted into the mounting groove 40, and the portion that is in close contact with the lower surface 42 of the valve seat 33 is vertically It is formed by a valve section 67 having an inverted cross-sectional umbrella shape, that is, a truncated cone shape, and this water stop member 66 is formed of an elastically deformable material such as silicon rubber or elastomer resin, and its peripheral edge is in close contact with the lower surface 42. It has a check valve shape.

したがって、操作部58を押圧すると止水部材68が下面42に密着した閉弁状態から、下降することで開弁することができる。そして、閉弁時に内容器が減圧状態になると弁膜部67が下側に吸引されて下面42より離れ、この結果内容器５の内側と大気とは、弁膜部67と下面42との隙間、弁座33と通気弁34との隙間、弁座33と弁棒36との隙間、通気孔25と円筒部64との隙間、蓋体14の大気と連通する隙間とを介して連通状態となる。   Therefore, when the operation portion 58 is pressed, the valve can be opened by descending from the closed state where the water stop member 68 is in close contact with the lower surface 42. When the inner container is in a decompressed state when the valve is closed, the valve membrane portion 67 is sucked downward and separated from the lower surface 42. As a result, the inner side of the inner vessel 5 and the atmosphere are the gap between the valve membrane portion 67 and the lower surface 42, the valve A communication state is established through a gap between the seat 33 and the vent valve 34, a gap between the valve seat 33 and the valve stem 36, a gap between the vent hole 25 and the cylindrical portion 64, and a gap communicating with the atmosphere of the lid body 14.

このような実施例においては、実施例１の作用効果の他に、止水部材66が内容器内の減圧時に一点鎖線で示すように弾性変形することで、操作部58を押圧しなくとも、内容器内の減圧状態を自動的に解消することができる。   In such an embodiment, in addition to the operational effects of the first embodiment, the water stop member 66 is elastically deformed as indicated by the alternate long and short dash line when the inner container is decompressed, so that the operation portion 58 is not pressed. The reduced pressure state in the inner container can be automatically eliminated.

図１０〜１２は実施例４を示しており、通気孔25に設けられる通気弁34は、通気孔25を閉塞するシリコンゴム、エラストマー樹脂等の弾性材料からなる断面ハット形状の弁膜部68の中央にスリット部（切れ目）69が放射状に設けられている。そして、棒状突起部54が弁膜部68の中央に間隔をおいて対向している。尚、実施例では通気弁34（弁膜部68）を飲み口部11や閉塞部材９と一体的に設けている。またスリット部69は十字状の他に＊状や一字状など、種々の形状で設けることができる。   FIGS. 10 to 12 show the fourth embodiment. The vent valve 34 provided in the vent hole 25 is the center of a valve membrane portion 68 having a hat-shaped cross section made of an elastic material such as silicon rubber or elastomer resin that closes the vent hole 25. Slit portions (cuts) 69 are provided radially. Further, the rod-like protrusions 54 are opposed to the center of the valve membrane part 68 with an interval. In the embodiment, the ventilation valve 34 (valve membrane portion 68) is provided integrally with the drinking mouth portion 11 and the closing member 9. In addition to the cross shape, the slit portion 69 can be provided in various shapes such as a * shape and a single character shape.

したがって、通気弁34が上面に膜状の弁膜部68と、該弁膜部68に切込み形成されるスリット部69とを設け、栓体本体７の通気孔25内に取付固定される。そして、係止解除ボタン16の棒状突起部54がスリット部69を押圧することにより、スリット部69が下側に向かい押し広げられて開弁作動する。   Therefore, the vent valve 34 is provided with a membrane-like valve membrane portion 68 on the upper surface and a slit portion 69 cut and formed in the valve membrane portion 68, and is attached and fixed in the vent hole 25 of the plug body 7. Then, when the rod-like protrusion 54 of the locking release button 16 presses the slit portion 69, the slit portion 69 is pushed downward and opened.

以上のように、本実施例では、実施例１の作用効果の他に、係止解除ボタン16が、通気弁34（弁膜部68）の一部を押圧して、飲料用容器本体２の内圧を通気孔25を通して大気圧へ開放することで、弁膜部68を弾性変形させ、内圧を開放することができる。また、内容物の吸引による減圧時等による減圧、加圧条件となった場合は、弾性部材の変形により一点鎖線で示すように大気圧へ開放することができる。さらに、部品点数を減らした構成でも、飲料用容器本体２の内圧を通気孔25を通して大気圧へ開放することができる。 As described above, in the present embodiment, in addition to the operational effects of the first embodiment, the lock release button 16 presses a part of the vent valve 34 (valve film portion 68), and the internal pressure of the beverage container body 2 is increased. Is released to atmospheric pressure through the vent hole 25 , the valve membrane portion 68 can be elastically deformed and the internal pressure can be released. In addition, when the pressure is reduced or increased due to the suction of the contents, the pressure can be released to the atmospheric pressure as indicated by the one-dot chain line by the deformation of the elastic member. Furthermore, the internal pressure of the beverage container body 2 can be released to the atmospheric pressure through the vent hole 25 even with a configuration in which the number of parts is reduced.

図１３および１４は実施例５を示しており、本実施例では、底部51における通気孔25の前側に取付孔70を形成し、該取付孔70内に弾性部材より成る通気弁34を装着している。通気弁34は取付孔70に装着する弁棒71と、この弁棒71の下端に設けられて底部51の下面に密着可能な上下逆の断面傘形状の弁膜部72とを設けたものであり、通気弁34の下部開口は、取付孔70と弁膜部72の周縁が密着する底部51の下面の部位との間に配置されている。すなわち、通気弁34の下部開口の下方は弁膜部72に覆われて気密状態となっている。   13 and 14 show a fifth embodiment. In this embodiment, a mounting hole 70 is formed in front of the vent hole 25 in the bottom 51, and a vent valve 34 made of an elastic member is mounted in the mounting hole 70. ing. The vent valve 34 is provided with a valve stem 71 to be mounted in the mounting hole 70, and a valve membrane portion 72 having an upside down cross-sectional umbrella shape that is provided at the lower end of the valve stem 71 and can be in close contact with the lower surface of the bottom 51. The lower opening of the vent valve 34 is disposed between the attachment hole 70 and the lower surface portion of the bottom 51 where the peripheral edge of the valve membrane portion 72 is in close contact. That is, the lower part of the lower opening of the vent valve 34 is covered with the valve membrane portion 72 and is airtight.

そして、係止解除ボタン16の棒状突起部54からさらに下方へ先細となって延長した延長部73を通気孔25に対向するように該通気孔25の上方に配置している。尚、延長部73は通気孔25に貫通したとき、通気孔25と延長部73との間には僅かな隙間が形成されるようになっ
ている。 Then, an extension 73 that tapers and extends further downward from the rod-shaped protrusion 54 of the lock release button 16 is disposed above the vent 25 so as to face the vent 25. Note that, when the extension portion 73 penetrates the vent hole 25, a slight gap is formed between the vent hole 25 and the extension portion 73.

そして、係止解除ボタンが下側へ向かい押圧されると、延長部73が通気孔25を上方から下方に向けて貫通し、その下端が弁膜部72を押圧し、弁膜部72の周縁が底部51より離れて開弁状態となる。このため、内容器５と大気間は弁膜部72の周縁が底部51より離れた隙間、通気孔25、蓋体14の大気と連通する隙間を介して連通状態となる。また、弁膜部72は逆止弁状であるので、内容器５の内部が内容物の吸引によって負圧になると、弁膜部72の周縁が底部51より離れて自動的に減圧状態を解消することができる。   When the unlocking button is pressed downward, the extension 73 penetrates the vent hole 25 from above to below, the lower end presses the valve membrane 72, and the periphery of the valve membrane 72 is the bottom. The valve is opened away from 51. For this reason, the inner container 5 and the atmosphere are in communication with each other through a gap in which the periphery of the valve membrane 72 is separated from the bottom 51, a gap communicating with the atmosphere in the vent hole 25, and the lid body 14. Further, since the valve membrane portion 72 has a check valve shape, when the inside of the inner container 5 becomes negative pressure due to the suction of the contents, the peripheral edge of the valve membrane portion 72 is separated from the bottom portion 51 to automatically eliminate the reduced pressure state. Can do.

このような実施例においても、実施例１と同様な作用効果の他に、係止解除ボタン16によって通気弁34（弁膜部72）の一部を押圧し、大気圧へ開放できる。また、内容物の吸引などの減圧時には通気弁34が弾性変形するため、自動的に減圧状態を解除できる。   In such an embodiment, in addition to the same effects as those of the first embodiment, a part of the vent valve 34 (valve membrane portion 72) can be pressed by the locking release button 16 to be released to the atmospheric pressure. Further, since the vent valve 34 is elastically deformed at the time of decompression such as suction of contents, the decompressed state can be automatically released.

図１５に示した実施例６は平面視で緊張状態の矩形に配置したリング状弾性部材62を示したもので、その一側をヒンジ部13の前側下部に掛け渡し、他側62Ｂをスライド係止部材
15の後端15Ｅに設けたフック部に掛け渡し、さらにその中間部62Ｃをヒンジ部13の後ろ側に掛け回すようにしている。そして、係止解除ボタン16に設けられる棒状突起部54は一側62Ａ、他側62Ｂ、左右一対の中間部62Ｃに囲まれた域に配置されている。 Example 6 shown in FIG. 15 shows a ring-shaped elastic member 62 arranged in a tensioned rectangular shape in plan view, one side of which is spanned to the lower front side of the hinge portion 13, and the other side 62B is connected to the slide. Stop member
15 is hung on the hook portion provided at the rear end 15E, and the intermediate portion 62C is hung around the rear side of the hinge portion 13. The rod-shaped protrusion 54 provided on the lock release button 16 is disposed in a region surrounded by one side 62A, the other side 62B, and a pair of left and right intermediate portions 62C.

このように、スライド係止部材15を閉状態に維持させるためにバネではなく、リング状弾性部材62を使用することで、係止解除ボタン16はリング状弾性部材62の内側に配置させることができ、小スペース化が可能となる。この結果、蓋体14内のスペースを有効活用できる。特にリング状弾性部材62の内側に係止解除ボタン16側を配置することで、蓋体14の内部のスペースを有効活用することができる。   Thus, the lock release button 16 can be disposed inside the ring-shaped elastic member 62 by using the ring-shaped elastic member 62 instead of the spring to maintain the slide locking member 15 in the closed state. It is possible to reduce the space. As a result, the space in the lid 14 can be effectively utilized. In particular, by arranging the locking release button 16 side inside the ring-shaped elastic member 62, the space inside the lid 14 can be effectively utilized.
