以下、図示の実施形態に基づき本発明を詳説する。
本発明に係る携帯用飲料ボトルは、図１に示すように、有底筒状のボトル本体１と、ボトル本体１に施蓋状に取着されると共に飲料吐出用の口部21を上方突出状に有する蓋部材２と、蓋部材２に水平状軸心Ｌ３廻りに揺動自在に枢着されると共に蓋部材２の口部21を密封するためのシール部材31を有するキャップ部材３と、蓋部材２に水平状の枢支軸心Ｌ６廻りにシーソー状揺動可能に設けられキャップ部材３を係止して閉状態に保持するためのロック部材６と、蓋部材２に水平状の枢着軸心Ｌ７廻りに揺動可能に設けられ閉状態のキャップ部材３に係合してロック部材６の操作面60を保護する（包囲して目隠しする）ロックカバー部材７と、を備えている。 Hereinafter, the present invention will be described in detail based on illustrated embodiments.
As shown in FIG. 1, a portable beverage bottle according to the present invention is attached to a bottle body 1 having a bottomed cylindrical shape and a lid shape on the bottle body 1 and protrudes upward from a mouth 21 for discharging a beverage. A lid member 2 having a shape, a cap member 3 pivotally attached to the lid member 2 around a horizontal axis L3 and having a seal member 31 for sealing the mouth 21 of the lid member 2; A locking member 6 is provided on the lid member 2 so as to be swingable in a seesaw-like manner around a horizontal pivot axis L6, and locks the cap member 3 so as to be held in a closed state. And a lock cover member 7 which is provided so as to be swingable around the axis L7 and engages with the cap member 3 in the closed state to protect (enclose and cover) the operation surface 60 of the lock member 6. .

そして、ロック部材６にてキャップ部材３が閉状態に保持され、かつ、ロックカバー部材７がキャップ部材３に係合してロック部材６を保護した図１の誤操作防止状態から、図２に示すように、ロックカバー部材７の上部が（使用者によって）前下方へ揺動されると、ロック部材６の操作面60が露出してロック部材６の操作が可能な誤操作防止解除状態となる。 Then, the lock member 6 holds the cap member 3 in the closed state, and the lock cover member 7 engages with the cap member 3 to protect the lock member 6, as shown in FIG. 2. As described above, when the upper portion of the lock cover member 7 is swung forward and downward (by the user), the operation surface 60 of the lock member 6 is exposed, and an erroneous operation prevention release state in which the lock member 6 can be operated is set.

図２の誤操作防止解除状態は、ロック部材６にてキャップ部材３が閉状態に保持されたキャップ閉ロック状態でもある。そして、誤操作防止解除状態から、図３に示すように、ロック部材６の操作面60が（使用者によって）後方へ押圧操作されると、ロック部材６とキャップ部材３との係止が解除されキャップ部材３が水平状軸心Ｌ３廻りに開閉揺動可能なキャップ開閉自在状態（閉ロック解除状態）となる。 2 is a cap closed lock state in which the cap member 3 is held in the closed state by the lock member 6. Then, when the operation surface 60 of the lock member 6 is pressed backward (by the user) from the erroneous operation prevention release state, as shown in FIG. 3, the lock member 6 and the cap member 3 are unlocked. The cap member 3 is in a cap openable / closable state (closed unlocking state) that can be opened and closed around the horizontal axis L3.

さらに、図１乃至図４に示すように、蓋部材２とキャップ部材３との枢着部４近傍において、キャップ部材３に開揺動方向の弾発付勢力を付与するためのシリコン製のブロック状のゴム部材50を、蓋部材２に埋設状に設けている。 Further, as shown in FIGS. 1 to 4, in the vicinity of the pivot portion 4 between the lid member 2 and the cap member 3, a silicon block for applying an elastic urging force in the open swinging direction to the cap member 3. A rubber member 50 is embedded in the lid member 2.

図１と図２及び図４（ａ）に示すように、ロック部材６によって閉状態に保持されているキャップ部材３の下端面部３ｂによって、ゴム部材50は押圧され（圧縮弾性変形させられ）、開揺動方向の弾発付勢力（弾性的復元力）を蓄えるように構成している。
つまり、図３及び図４（ｃ）に示すように、ゴム部材50は、キャップ部材３による押圧が解除された状態（キャップ開状態）で、ゴム部材50の上部50ａが蓋上面２ａから上方へ突出するように埋設状に設けている。つまり、本発明では「埋設状」とは、全高の５０％以上が有底小孔部25に挿入保持されている状態を言う。 As shown in FIGS. 1, 2, and 4 (a), the rubber member 50 is pressed (compressed and elastically deformed) by the lower end surface portion 3 b of the cap member 3 held in the closed state by the lock member 6. It is configured to store an elastic urging force (elastic restoring force) in the open swing direction.
That is, as shown in FIG. 3 and FIG. 4C, the rubber member 50 is in a state where the pressing by the cap member 3 is released (cap open state), and the upper portion 50a of the rubber member 50 is moved upward from the lid upper surface 2a. It is provided in a buried shape so as to protrude. That is, in the present invention, the “embedded shape” means a state in which 50% or more of the total height is inserted and held in the bottomed small hole portion 25.

ゴム部材50は、水平状軸心Ｌ３よりも前方（キャップ開閉先端側）で、蓋上面２ａに凹設した有底小孔部25に挿入され保持（固着）されている。
キャップ閉状態でゴム部材50の上部50ａが水平状軸心Ｌ３よりも前方かつ上方位置でキャップ部材３に弾発付勢力を付与している。 The rubber member 50 is inserted and held (fixed) in a bottomed small hole portion 25 recessed in the lid upper surface 2a, in front of the horizontal axis L3 (cap opening / closing tip side).
When the cap is closed, the upper portion 50a of the rubber member 50 applies a resilient biasing force to the cap member 3 at a position in front of and above the horizontal axis L3.

ゴム部材50は、図２の誤操作防止解除状態（キャップ閉ロック状態）から、ロック部材６の操作面60が押圧される閉ロック解除操作が行われると、図４（ａ）、図４（ｂ）、図４（ｃ）に順次示すように、ゴム部材50（主として上部50ａ）が弾性的復元力を発揮し、キャップ部材３を開揺動方向へ弾発付勢する。キャップ部材３は、ゴム部材50から受けた弾発付勢により図３に示すように、開状態となる。 When the rubber member 50 is closed and unlocked by pressing the operation surface 60 of the lock member 6 from the erroneous operation prevention release state (cap closed lock state) shown in FIG. 2, the rubber member 50 shown in FIGS. 4 (c), the rubber member 50 (mainly the upper portion 50a) exerts an elastic restoring force, and elastically biases the cap member 3 in the open swinging direction. The cap member 3 is in an open state as shown in FIG.

図４（ａ）に二点鎖線で示すように、キャップ部材３から押圧されていない（押圧前の）ゴム部材50の上部（突出部）50ａの前後幅寸法をＷとすると、キャップ部材３による押圧前後範囲Ｓは、ゴム部材50の上部後端（突出部後端）50ｃからＷの６０％以上９０％以下とするのが好ましい。６０％未満であると、弾発付勢力が弱く、９０％を超えると、使用者がキャップ部材３を閉操作するのが困難になると共に、ゴム部材50や、ロック部材６とキャップ部材３との係止部に負荷がかかり耐久性が低下する虞がある。
また、キャップ部材３によってゴム部材50の上部前端近傍を押圧しない（９０％を超えない）ことで、図４（ａ）（ｂ）に示すようにキャップ部材３で押圧すると、ゴム部材50の上部前端が膨出するように（前上方へ逃げるように）弾性変形し、キャップ部材３を斜め上後方へ揺動させる弾発付勢力を蓄えることができて、キャップ部材３をスムーズに開揺動させることが可能となる。 As shown by a two-dot chain line in FIG. 4A, when the front-rear width dimension of the upper portion (projecting portion) 50a of the rubber member 50 that is not pressed from the cap member 3 (before pressing) is W, the cap member 3 The range S before and after pressing is preferably 60% to 90% of W from the upper rear end (protruding portion rear end) 50c of the rubber member 50. If it is less than 60%, the elastic biasing force is weak, and if it exceeds 90%, it becomes difficult for the user to close the cap member 3, and the rubber member 50, the lock member 6 and the cap member 3 There is a risk that the load will be applied to the locking portion of this and the durability will be reduced.
In addition, when the cap member 3 does not press the vicinity of the upper front end of the rubber member 50 (does not exceed 90%), when the cap member 3 is pressed as shown in FIGS. Elastically deforms so that the front end swells (escapes upward and upward), and can store the elastic urging force that swings the cap member 3 obliquely upward and rearward. It becomes possible to make it.

図５に示すように、ゴム部材50（有底小孔部25）は、平面視で円弧状であって、キャップ部材３の外周壁部35に対応するように配設している。
つまり、ゴム部材50を押圧するキャップ部材３の下端面部３ｂは、主として、キャップ部材３の後方側（枢着部４近傍）の外周壁部35の下面部であり、僅かではあるが、外周壁部35から後方突出状の枢着用膨出部34の下面部を含む。
このように構成することで、蓋部材２（蓋上面２ａ側や口部21の周囲）やキャップ部材３を、シンプルで美観に優れたものとすることができる。 As shown in FIG. 5, the rubber member 50 (the bottomed small hole portion 25) has an arc shape in plan view, and is disposed so as to correspond to the outer peripheral wall portion 35 of the cap member 3.
That is, the lower end surface portion 3b of the cap member 3 that presses the rubber member 50 is mainly the lower surface portion of the outer peripheral wall portion 35 on the rear side (near the pivoting portion 4) of the cap member 3, and a slight amount of the outer peripheral wall portion. It includes a lower surface portion of the pivoted bulging portion 34 that protrudes backward from the portion 35.
By comprising in this way, the cover member 2 (the cover upper surface 2a side and the periphery of the mouth part 21) and the cap member 3 can be made simple and excellent in aesthetics.

また、図３に示すように、ゴム部材50によって開状態になったキャップ部材３が、（使用者にて）さらに開揺動方向へ揺動されると、枢着部４近傍においてキャップ部材３の下端面部３ｂに設けた凹状の第１係止部38（図４参照）に、枢着部４近傍において蓋部材２に設けた凸状の第２係止部28（図４参照）が嵌合して、キャップ部材３を開状態に保持するキャップ開ロック状態（図示省略）となる。飲料をコップ等に注ぐ際や口部21から直接的に飲料を飲む際に、ボトル本体１を傾けてもキャップ部材３の開状態が保持され至便である。キャップ開閉揺動方向へ所定の操作力が付与されることで、第１係止部38と第２係止部28及びその近傍部位が弾性変形して係脱自在となる。
つまり、キャップ部材３を、キャップ閉ロック状態と、キャップ開閉自在状態と、キャップ開ロック状態と、に切換え可能に構成している。 As shown in FIG. 3, when the cap member 3 opened by the rubber member 50 is further swung in the open swinging direction (by the user), the cap member 3 near the pivoting portion 4. A convex second locking portion 28 (see FIG. 4) provided on the lid member 2 in the vicinity of the pivoting portion 4 is fitted into the concave first locking portion 38 (see FIG. 4) provided on the lower end surface portion 3b of the base plate. Accordingly, a cap open lock state (not shown) that holds the cap member 3 in the open state is obtained. When the beverage is poured into a cup or the like or when the beverage is directly drink from the mouth portion 21, the cap member 3 is kept open even if the bottle body 1 is tilted. When a predetermined operating force is applied in the cap opening / closing swinging direction, the first locking portion 38, the second locking portion 28, and the vicinity thereof are elastically deformed to be freely engaged and disengaged.
That is, the cap member 3 is configured to be switchable between a cap closed locked state, a cap openable / closable state, and a cap open locked state.

図１及び図２に於て、キャップ部材３は、外周壁部35の前方側に、ロック部材６と係合するためのロック用のキャップ爪部33と、キャップ爪部33よりも上方位置でロックカバー部材７が係合するための凸状の第１係合部37と、を有している。
蓋部材２は、周壁部26の前方側に、ロック部材６の上部（ロック爪部63）が、キャップ部材３との所定の係止位置（ロック位置）を超えて後方へ揺動するのを阻止するストッパー部27を有している。 1 and 2, the cap member 3 has a locking claw portion 33 for engaging with the locking member 6 on the front side of the outer peripheral wall portion 35, and a position above the cap claw portion 33. And a convex first engaging portion 37 for engaging the lock cover member 7.
In the lid member 2, the upper portion (lock claw portion 63) of the lock member 6 swings backward beyond a predetermined locking position (lock position) with the cap member 3 on the front side of the peripheral wall portion 26. A stopper portion 27 for blocking is provided.

ロック部材６は、樹脂成型品であって、上部（枢支軸心Ｌ６よりも上方位置）に、キャップ部材３のキャップ爪部33と係合するためのロック爪部63と、上記所定の係止位置でストッパー部27に当接する当り部（面）68と、を有している。
さらに、ロック部材６は、下部（枢支軸心Ｌ６よりも下方位置）を縦断面レの字状に形成している。そして、下部の前面（表て面）を操作面60とし、下部のレの字状の後方折曲げ（折り返し）部位を、上記係止位置にロック爪部63を弾発付勢するための弾性片部69としている。 The lock member 6 is a resin molded product, and has a lock claw portion 63 for engaging with the cap claw portion 33 of the cap member 3 at the upper portion (above the pivot axis L6), and the predetermined engagement. And a contact portion (surface) 68 that contacts the stopper portion 27 at the stop position.
Furthermore, the lock member 6 has a lower portion (a position below the pivot axis L6) formed in a letter shape in a longitudinal section. The lower front surface (representing surface) is the operation surface 60, and the lower letter-shaped rearwardly folded (folded) portion is elastic for elastically biasing the lock claw 63 to the above-mentioned locking position. One part 69 is provided.

弾性片部69は、蓋部材２の周壁部26の前方側に常時当接して、ロック部材６の下部を前方へ常時弾発付勢している。
つまり、図３に示すように、ロック部材６は、操作面60が押圧操作されると、弾性片部69が蓋部材２の周壁部26に押圧されレの字がさらに折れ曲がるように弾性変形する。そして、押圧操作力が解除されると、図６に示すように、弾性片部69の弾発付勢力（弾性的復元力）によって、当り部68がストッパー部27に当接し、ロック爪部63が所定の係止位置に配設される（押圧操作前の位置に戻る）。 The elastic piece portion 69 is always in contact with the front side of the peripheral wall portion 26 of the lid member 2 and constantly elastically biases the lower portion of the lock member 6 forward.
That is, as shown in FIG. 3, when the operation surface 60 is pressed, the lock member 6 is elastically deformed so that the elastic piece 69 is pressed against the peripheral wall portion 26 of the lid member 2 and the letter C is further bent. . When the pressing operation force is released, as shown in FIG. 6, the contact portion 68 comes into contact with the stopper portion 27 by the elastic urging force (elastic restoring force) of the elastic piece portion 69, and the lock claw portion 63. Is disposed at a predetermined locking position (returns to the position before the pressing operation).

そして、使用者が、ゴム部材50に抗してキャップ部材３を閉揺動させると、ロック爪部63の上面側に後方下傾状に形成した摺接面に、キャップ爪部33の下面側に前方上傾状に形成したガイド面が摺接し、ロック爪部63が（弾性片部69に抗して）前方へ揺動するように逃げて、キャップ爪部33がロック爪部63を乗り越える。
その後、弾性片部69の弾性的復元力によってロック爪部63が係止位置に戻って、図２に示すように、キャップ爪部33と係合する。 When the user closes and swings the cap member 3 against the rubber member 50, the lower surface side of the cap claw portion 33 is formed on the slidable contact surface formed on the upper surface side of the lock claw portion 63 in a downwardly inclined manner. The guide surface formed in an upwardly inclined manner comes into sliding contact with the lock claw portion 63 so that the lock claw portion 63 swings forward (against the elastic piece portion 69), and the cap claw portion 33 gets over the lock claw portion 63. .
Thereafter, the lock claw 63 returns to the locking position by the elastic restoring force of the elastic piece 69 and engages with the cap claw 33 as shown in FIG.

図２に於て、ロック爪部63とキャップ爪部33とが係止したロック状態（キャップ閉ロック状態）で、キャップ部材３のシール部材31が、口部21に密着して（シールして）、飲料の漏れを防止する。 In FIG. 2, the seal member 31 of the cap member 3 is in close contact (sealed) with the mouth portion 21 in the locked state where the lock claw portion 63 and the cap claw portion 33 are locked (cap closed lock state). ) To prevent beverage leakage.

さらに、図２及び図７のキャップ閉ロック状態（誤操作防止解除状態）において、キャップ部材３の下端面部３ｂが蓋部材２の蓋上面２ａに当接している。より具体的には、キャップ部材３の外周壁部35の下端面や、外周壁部35から前方突出状に設けられキャップ爪部33の左右両側を保護する左右一対の前方突出壁部39，39の下端面等が、蓋上面２ａに当接している。 2 and 7, the lower end surface portion 3b of the cap member 3 is in contact with the lid upper surface 2a of the lid member 2 in the cap closed lock state (incorrect operation prevention release state). More specifically, a pair of left and right front projecting wall portions 39, 39 that are provided in a forward projecting shape from the lower end surface of the outer peripheral wall portion 35 of the cap member 3 and protect the both left and right sides of the cap claw portion 33. Is in contact with the lid upper surface 2a.

つまり、キャップ閉ロック状態において、キャップ部材３は閉揺動方向の揺動が蓋部材２の蓋上面２ａ（後述の蓋本体20の上壁部23）によって阻止され、開揺動方向の揺動がロック部材６によって阻止され、開閉どちらにも揺動不可能となる。したがって、キャップ部材３のガタ付きがなく、また、シール部材31が所定の密着力をもって安定的に、口部21を施蓋状に密閉（シール）し、飲料漏れを確実に防止する。 That is, in the cap closed lock state, the cap member 3 is prevented from swinging in the closing swing direction by the lid upper surface 2a of the lid member 2 (upper wall portion 23 of the lid body 20 described later), and swinging in the open swing direction. Is blocked by the lock member 6 and cannot be swung in both the open and closed states. Therefore, there is no backlash of the cap member 3, and the sealing member 31 stably seals (seals) the mouth portion 21 in a lid shape with a predetermined adhesion force, thereby reliably preventing beverage leakage.

次に、ロックカバー部材７は、横断面コの字状の樹脂成型品であって、先端部にキャップ部材３と係合するための凸状の第２係合部73を有し、基端部がロック部材６よりも下方位置で蓋部材２に枢着している。 Next, the lock cover member 7 is a resin molded product having a U-shaped cross section, and has a convex second engaging portion 73 for engaging with the cap member 3 at the distal end, The part is pivotally attached to the lid member 2 at a position below the lock member 6.

図２及び図７のキャップ閉ロック状態（誤操作防止解除状態）から、ロックカバー部材７の先端部を上方へ揺動させると、キャップ部材３の第１係合部37及びロックカバー部材７の第２係合部73が相互に弾性変形して第２係合部73が第１係合部37を乗り越えて、図１及び図８に示すように、ロックカバー部材７がキャップ部材３によって起立状に係止される。ロックカバー部材７によって、ロック部材６が包囲され（操作面60が保護され）、ロック部材６の誤操作が防止される誤操作防止状態となる。 When the tip of the lock cover member 7 is swung upward from the cap closed lock state (incorrect operation prevention release state) of FIGS. 2 and 7, the first engagement portion 37 of the cap member 3 and the lock cover member 7 The two engaging portions 73 are elastically deformed with each other, the second engaging portion 73 gets over the first engaging portion 37, and the lock cover member 7 is raised by the cap member 3 as shown in FIGS.
