Description

開閉自在容器Openable / closable container
　本発明は、例えば取出口を有する本体と、本体に対して開閉自在な開閉蓋とを有する開閉自在容器に関する。 The present invention relates to an openable / closable container having, for example, a main body having an outlet and an open / close lid that can be opened and closed with respect to the main body.
　例えばウェットティッシュを内部に収納する開閉自在容器は、ウェットティッシュ等を収納するとともにウェットティッシュ等の取出口を有する容器本体と、取出口を開閉自在に密閉する開閉蓋とを備えている。 For example, an openable / closable container for storing a wet tissue includes a container body that stores a wet tissue and the like and has an outlet for the wet tissue, and an open / close lid that seals the outlet for opening and closing.
　使用に際しては、容器本体の取出口に対して開閉蓋が開かれ、容器本体の取出口からウェットティッシュ等が一枚ずつ取出される。 In use, the opening / closing lid is opened with respect to the outlet of the container body, and wet tissues and the like are taken out one by one from the outlet of the container body.
特開２００３－１７０９５０号公報JP 2003-170950 A
　上述のように、従来の開閉自在容器は容器本体と、この容器本体に対して揺動自在に取付けられた開閉蓋とを備えており、使用に際しては開閉蓋を揺動させ、容器本体の取出口からウェットティッシュ等を取出している。 As described above, a conventional openable / closable container includes a container main body and an open / close lid that is swingably attached to the container main body. In use, the open / close lid is swung to remove the container main body. Wet tissue etc. is taken out from the exit.
　ところで、例えば特開２００３－１７０９５０号公報にも示されているように、容器本体と開閉蓋との間には、開閉蓋を開方向に付勢する付勢手段が設けられている。また容器本体の正面側には、開閉蓋を開くための押しボタンが設けられており、押しボタンを操作した際、付勢手段によって開閉蓋が開かれるようになっている。 Incidentally, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2003-170950, an urging means for urging the opening / closing lid in the opening direction is provided between the container body and the opening / closing lid. In addition, a push button for opening the opening / closing lid is provided on the front side of the container body, and when the push button is operated, the opening / closing lid is opened by the urging means.

　さらに背側段部２５のうち開閉蓋２３のスプリング体３４に対応する位置に、スロープ部（制動部）４３が設けられている。スロープ部４３は、開閉蓋２３を開位置から閉位置にもっていく際、スプリング体３４が当接しながら摺動するものである。 Furthermore, a slope portion (braking portion) 43 is provided at a position corresponding to the spring body 34 of the opening / closing lid 23 in the back side step portion 25. The slope 43 slides while the spring body 34 abuts when the opening / closing lid 23 is moved from the open position to the closed position.
　次に図１２乃至図１４により、スロープ部（制動部）４３の構成について説明する。図１２は、開閉蓋２３が全閉位置にあるときの、開閉自在容器１０の部分断面図（揺動軸Ｘ－Ｘに垂直な断面図）であり、図１３は、開閉蓋２３が全開位置にあるときの、開閉自在容器１０の部分断面図（揺動軸Ｘ－Ｘに垂直な断面図）である。また図１４は、スプリング体３４がスロープ部４３に沿って移動する状態を示す図（揺動軸Ｘ－Ｘに垂直な断面図）である。 Next, the configuration of the slope portion (braking portion) 43 will be described with reference to FIGS. FIG. 12 is a partial cross-sectional view (cross-sectional view perpendicular to the swing axis XX) of the openable / closable container 10 when the open / close lid 23 is in the fully closed position, and FIG. FIG. 6 is a partial cross-sectional view (cross-sectional view perpendicular to the swing axis XX) of the openable / closable container 10 when in the position shown in FIG. FIG. 14 is a view showing a state in which the spring body 34 moves along the slope portion 43 (cross-sectional view perpendicular to the swing axis XX).
　図１２および図１３に示すように、スロープ部４３は、側面方向から見て容器本体１１内方（図１２および図１３の左方向）に向けて湾曲した弧状の内面４３ａを有するリブからなっている。また、スロープ部４３は、その内面４３ａと揺動軸Ｘ－Ｘとの間の距離が、開閉蓋２３が閉のときの状態から開のときの状態に向けて、徐々に狭まるように構成されている。 As shown in FIGS. 12 and 13, the slope portion 43 is composed of a rib having an arc-shaped inner surface 43 a that is curved toward the inside of the container body 11 (leftward in FIGS. 12 and 13) when viewed from the side. Yes. Further, the slope portion 43 is configured such that the distance between the inner surface 43a and the swing axis XX gradually narrows from the state when the opening / closing lid 23 is closed to the state when it is opened. ing.
　すなわち図１４に示すように、スロープ部４３の下端部４３ｂと揺動軸Ｘ－Ｘとの間の距離をｄ1とする。また、開閉蓋２３が全開状態（図１３参照）となった際にスプリング体３４が当接するスロープ部４３の位置を符号４３ｃ（以下、全開点４３ｃともいう）で示す。また当該全開点４３ｃと揺動軸Ｘ－Ｘとの間の距離をｄ2とする。 That is, as shown in FIG. 14, the distance between the lower end portion 43b and the rocking shaft X-X of the slope portion 43 and the d 1. The position of the slope portion 43 with which the spring body 34 abuts when the open / close lid 23 is in the fully open state (see FIG. 13) is indicated by reference numeral 43c (hereinafter also referred to as a fully open point 43c). Also the distance between the fully opened point 43c and the swing axis X-X and d 2.
　この場合、スロープ部４３の内面４３ａと揺動軸Ｘ－Ｘとの間の距離は、下端部４３ｂから全開点４３ｃにかけて徐々に狭まっている。すなわち、下端部４３ｂと全開点４３ｃとの間の位置４３ｄと、揺動軸Ｘ－Ｘとの間の距離をｄ3とした場合、ｄ1＞ｄ3＞ｄ2の関係が成り立っている。 In this case, the distance between the inner surface 43a of the slope portion 43 and the swing axis XX gradually decreases from the lower end portion 43b to the full open point 43c. That is, the position 43d between the lower end portion 43b and the fully opened point 43c, and the distance between the oscillation axis X-X and a d 3, d 1> d 3 > relationship d 2 is established.
　なお、スロープ部４３は、全開点４３ｃの直前までスプリング体３４が内面４３ａに当接しないような形状としてもよい。このような形状とすることにより、開閉蓋２３を閉から開とする際、開閉蓋２３が全開位置（全開点４３ｃ）に移動している途中で停止することを防止することができる。 In addition, the slope part 43 is good also as a shape where the spring body 34 does not contact | abut to the inner surface 43a until just before the full open point 43c. By adopting such a shape, when the opening / closing lid 23 is opened from the closed state, it is possible to prevent the opening / closing lid 23 from stopping during the movement to the fully opened position (fully opened point 43c).
　あるいは、図１５に示すように、スロープ部４３の内面４３ａを円弧状に形成してもよい。 Alternatively, as shown in FIG. 15, the inner surface 43a of the slope portion 43 may be formed in an arc shape.
　なお取出口２４（マウス部）の形状は、図１に示すものに限られず、例えば図１８に示すように、第１上板２７ａに設けられた凹部９４内において、取出口２４の周囲にフラップ３９が設けられていてもよい。 The shape of the outlet 24 (mouse portion) is not limited to that shown in FIG. 1. For example, as shown in FIG. 18, a flap is formed around the outlet 24 in a recess 94 provided in the first upper plate 27 a. 39 may be provided.
　次にこのような構成からなる本実施の形態の作用について説明する。 Next, the operation of the present embodiment having such a configuration will be described.
　ウェットティッシュ４１を使用する際、まずユーザーが操作ボタン５５の天板部６５を押圧する。これにより、係止片３２と爪部６６との係合が解除される。この場合、板ゴム５０の復元力により、開閉蓋２３が開となる。 When using the wet tissue 41, the user first presses the top plate portion 65 of the operation button 55. As a result, the engagement between the locking piece 32 and the claw portion 66 is released. In this case, the opening / closing lid 23 is opened by the restoring force of the rubber plate 50.
　すなわち、開閉蓋２３は、板ゴム５０に付勢され、揺動軸Ｘ－Ｘを中心に開方向（図１２の時計回り方向）に回動する。 That is, the opening / closing lid 23 is urged by the rubber plate 50 and rotates in the opening direction (clockwise direction in FIG. 12) about the swing axis XX.
　この間、スプリング体３４とスロープ部４３との作用は以下のようになる。まず図１２に示す全閉状態において、スプリング体３４は、容器本体１１の背側段部２５およびスロープ部４３から離れた位置にある。 During this time, the action of the spring body 34 and the slope portion 43 is as follows. First, in the fully closed state shown in FIG. 12, the spring body 34 is located away from the back side step portion 25 and the slope portion 43 of the container body 11.
　次に、開閉蓋２３が板ゴム５０の復元力により開方向に回動すると、これに伴ってスプリング体３４もスロープ部４３側に移動し、スプリング体３４がスロープ部４３の内面４３ａに当接する（図１４参照）。 Next, when the opening / closing lid 23 is rotated in the opening direction by the restoring force of the rubber plate 50, the spring body 34 is also moved to the slope portion 43 side, and the spring body 34 comes into contact with the inner surface 43a of the slope portion 43. (See FIG. 14).
　続いて開閉蓋２３が更に回動することにより、スプリング体３４は、スロープ部４３の内面４３ａに沿って全開点４３ｃに向けて上昇する。 Subsequently, when the opening / closing lid 23 further rotates, the spring body 34 rises toward the fully open point 43 c along the inner surface 43 a of the slope portion 43.
　この場合、上述したように、スロープ部４３の内面４３ａと揺動軸Ｘ－Ｘとの間の距離は、下端部４３ｂから全開点４３ｃにかけて徐々に狭まっている。したがって、スプリング体３４は、スロープ部４３に沿って上昇するにしたがって徐々に圧縮されていく（図１４参照）。このようにスプリング体３４が圧縮されることにより、板ゴム５０の付勢力に抗して、開閉蓋２３の回動速度が抑えられる。 In this case, as described above, the distance between the inner surface 43a of the slope portion 43 and the swing axis XX gradually decreases from the lower end portion 43b to the full open point 43c. Accordingly, the spring body 34 is gradually compressed as it rises along the slope portion 43 (see FIG. 14). By compressing the spring body 34 in this manner, the rotation speed of the opening / closing lid 23 is suppressed against the urging force of the rubber plate 50.
　その後、開閉蓋２３が全開位置に達すると、開閉蓋２３の基端縁部２３ｄがストッパ３０に係止して開閉蓋２３が停止する（図１３参照）。 Thereafter, when the opening / closing lid 23 reaches the fully open position, the base end edge 23d of the opening / closing lid 23 is locked to the stopper 30 and the opening / closing lid 23 stops (see FIG. 13).
　この際、図１３に示すように、スプリング体３４の実際の形状（実線で示す）は、仮想線で示す本来のスプリング体の形状（符号３４Ｘ）と比べて圧縮されている。このようにスプリング体３４がスロープ部４３に対して復元力を加えることにより、開閉蓋２３の回転速度を抑え、開閉蓋２３を全開位置で緩やかに停止させることができる。 At this time, as shown in FIG. 13, the actual shape (indicated by a solid line) of the spring body 34 is compressed as compared with the original shape of the spring body (reference numeral 34X) indicated by an imaginary line. Thus, the spring body 34 applies a restoring force to the slope portion 43, so that the rotational speed of the open / close lid 23 can be suppressed and the open / close lid 23 can be gently stopped at the fully open position.
　次に容器本体１１の取出口２４からウェットティッシュ４１を指で摘んで上方へ引っ張り出し、使用する。 Next, the wet tissue 41 is picked with a finger from the outlet 24 of the container body 11 and pulled upward to use.
　以上のように本実施の形態によれば、開閉蓋２３が全開となる前に、開閉蓋２３のスプリング体３４が、容器本体１１のスロープ部（制動部）４３の内面４３ａに沿って徐々に圧縮される。これにより開閉蓋２３を少しずつ減速させることができ、全開位置で緩やかに停止させることができる。したがって、開閉蓋２３がストッパ３０に当接した後、開閉蓋２３を振動させずに直ちに静止させることができる。 As described above, according to the present embodiment, before the opening / closing lid 23 is fully opened, the spring body 34 of the opening / closing lid 23 gradually moves along the inner surface 43a of the slope portion (braking portion) 43 of the container body 11. Compressed. Thereby, the opening / closing lid 23 can be decelerated little by little, and can be gently stopped at the fully opened position. Therefore, after the opening / closing lid 23 comes into contact with the stopper 30, the opening / closing lid 23 can be immediately stopped without vibrating.
　また本実施の形態によれば、開閉蓋２３を全開位置で緩やかに停止させるための機構が簡単である。すなわち、スプリング体３４は、開閉蓋２３と一体成形することができ、スロープ部４３は、容器本体１１と一体成形することができるので、このような機構を低コストで容易に実現することができる。 Further, according to the present embodiment, the mechanism for gently stopping the open / close lid 23 at the fully open position is simple. That is, since the spring body 34 can be integrally formed with the open / close lid 23 and the slope portion 43 can be integrally formed with the container body 11, such a mechanism can be easily realized at low cost. .

　このようにＣ字状部材４５の外周４５ｃに突起４８ａ－４８ｃが設けられていることにより、開閉蓋２３を開閉動作させる際に、Ｃ字状部材４５が筒状体４７内でがたつくことを防止することができ、開閉蓋２３を安定して開閉することができる。 As described above, the protrusions 48a to 48c are provided on the outer periphery 45c of the C-shaped member 45, thereby preventing the C-shaped member 45 from rattling in the cylindrical body 47 when the opening / closing lid 23 is opened / closed. The opening / closing lid 23 can be opened and closed stably.
　他方、図１９および図２１に示すように、容器本体１１側にはＣ字状部材４５外周を取り囲む筒状体（制動部）４７が設けられている。筒状体４７は、揺動軸Ｘ－Ｘに平行に延びるとともに、内部に開閉蓋２３のＣ字状部材４５が挿着されるようになっている。また筒状体４７は、上述した突起４８ａ－４８ｃが当接する内面４７ｃを有している。 On the other hand, as shown in FIGS. 19 and 21, a cylindrical body (braking part) 47 surrounding the outer periphery of the C-shaped member 45 is provided on the container body 11 side. The cylindrical body 47 extends in parallel with the swing axis XX, and the C-shaped member 45 of the opening / closing lid 23 is inserted therein. The cylindrical body 47 has an inner surface 47c with which the above-described protrusions 48a-48c abut.
　図２２に示すように、筒状体４７は、揺動軸Ｘ－Ｘを中心として均一な半径Ｒ1を有する等径部４７ａと、揺動軸Ｘ－Ｘを中心として半径がＲ1からＲ2（＜Ｒ1）まで徐々に縮小する縮径部４７ｂとからなっている。すなわちこの縮径部４７ｂにおいては、内面４７ｃと揺動軸Ｘ－Ｘとの間の距離が、開閉蓋２３が閉のときの状態から、開のときの状態に向けて、徐々に狭まるようになっている。 As shown in FIG. 22, the cylindrical body 47 has an equal-diameter portion 47a having a uniform radius R 1 around the swing axis XX, and a radius from R 1 to R around the swing axis XX. 2 (<R 1 ), and a reduced diameter portion 47b that gradually decreases. That is, in the reduced diameter portion 47b, the distance between the inner surface 47c and the swing axis XX is gradually reduced from the state when the opening / closing lid 23 is closed to the state when the opening / closing lid 23 is opened. It has become.
　本実施の形態において、揺動軸Ｘ－Ｘを中心とした場合の等径部４７ａの角度は約２６０°であり、縮径部４７ｂの角度は約１００°であるが、これに限定されるものではない。 In the present embodiment, the angle of the equal-diameter portion 47a around the swing axis XX is about 260 °, and the angle of the reduced-diameter portion 47b is about 100 °, but is not limited thereto. It is not a thing.
　次にこのような構成からなる本実施の形態の作用について説明する。 Next, the operation of the present embodiment having such a configuration will be described.
　まずユーザーが操作ボタン５５を押圧することにより、係止片３２と爪部６６との係合が解除される（図１参照）。この場合、板ゴム５０の復元力により、開閉蓋２３が開となる。 First, when the user presses the operation button 55, the engagement between the locking piece 32 and the claw portion 66 is released (see FIG. 1). In this case, the opening / closing lid 23 is opened by the restoring force of the rubber plate 50.
　この際、開閉蓋２３は板ゴム５０に付勢され、揺動軸Ｘ－Ｘを中心に開方向（図２３（ａ）（ｂ）の反時計回り方向）に回動する。なお、図２３（ａ）は、全閉状態における、Ｃ字状部材４５と筒状体４７との関係を示す図であり、図２３（ｂ）は、全開状態における、Ｃ字状部材４５と筒状体４７との関係を示す図である。 At this time, the opening / closing lid 23 is urged by the rubber plate 50 and rotates in the opening direction (counterclockwise in FIGS. 23A and 23B) about the swing axis XX. FIG. 23A is a diagram showing a relationship between the C-shaped member 45 and the cylindrical body 47 in the fully closed state, and FIG. 23B is a diagram showing the relationship between the C-shaped member 45 in the fully opened state. It is a figure which shows the relationship with the cylindrical body 47. FIG.
　この間、Ｃ字状部材４５と筒状体４７との作用は以下のようになる。まず図２３（ａ）に示す全閉状態において、Ｃ字状部材４５の弾性部４５ｂは、撓んでいない状態にある。 During this time, the operation of the C-shaped member 45 and the cylindrical body 47 is as follows. First, in the fully closed state shown in FIG. 23A, the elastic portion 45b of the C-shaped member 45 is not bent.
　次に、開閉蓋２３が板ゴム５０の復元力により開方向に回動すると、これに伴ってＣ字状部材４５も筒状体４７内で開方向（図２３（ａ）に矢印で示す方向）に回動し、Ｃ字状部材４５の外周４５ｃに設けられた各突起４８ａ－４８ｃが筒状体４７の内面４７ｃに沿って摺動する。 Next, when the opening / closing lid 23 is rotated in the opening direction by the restoring force of the rubber plate 50, the C-shaped member 45 is also moved in the opening direction in the cylindrical body 47 (the direction indicated by the arrow in FIG. 23A). ) And the protrusions 48 a to 48 c provided on the outer periphery 45 c of the C-shaped member 45 slide along the inner surface 47 c of the cylindrical body 47.
　続いて開閉蓋２３が更に回動することにより、Ｃ字状部材４５の弾性部４５ｂに設けられた突起４８ａが縮径部４７ｂに達する。更に弾性部４５ｂの突起４８ａは、縮径部４７ｂに沿って筒状体４７の内面４７ｃを摺動する。 Subsequently, when the opening / closing lid 23 further rotates, the protrusion 48a provided on the elastic portion 45b of the C-shaped member 45 reaches the reduced diameter portion 47b. Further, the protrusion 48a of the elastic portion 45b slides on the inner surface 47c of the cylindrical body 47 along the reduced diameter portion 47b.
　この場合、上述したように、筒状体４７の縮径部４７ｂにおいて、内面４７ｃと揺動軸Ｘ－Ｘとの間の距離は、開閉蓋２３が閉のときの状態から開のときの状態に向けて、徐々に狭まっている。したがって、Ｃ字状部材４５の弾性部４５ｂは、弾性部４５ｂ上の突起４８ａが縮径部４７ｂの内面４７ｃに沿って移動するにしたがって、徐々に内方に撓んでいく（図２３（ｂ）参照）。このようにＣ字状部材４５が撓むことにより、板ゴム５０の付勢力に抗して、開閉蓋２３の回動速度が抑えられる。 In this case, as described above, in the reduced diameter portion 47b of the cylindrical body 47, the distance between the inner surface 47c and the swing axis XX is the state when the open / close lid 23 is opened from the closed state. It is gradually narrowing towards. Therefore, the elastic portion 45b of the C-shaped member 45 is gradually bent inward as the protrusion 48a on the elastic portion 45b moves along the inner surface 47c of the reduced diameter portion 47b (FIG. 23B). reference). As the C-shaped member 45 is bent in this manner, the rotation speed of the opening / closing lid 23 is suppressed against the urging force of the rubber plate 50.
　その後、開閉蓋２３が全開位置に達すると、開閉蓋２３の基端縁部２３ｄがストッパ３０に当接して開閉蓋２３が停止する。 Thereafter, when the opening / closing lid 23 reaches the fully open position, the base end edge 23d of the opening / closing lid 23 comes into contact with the stopper 30 and the opening / closing lid 23 stops.
　この際、図２３（ｂ）に示すように、弾性部４５ｂの実際の形状（実線で示す）は、仮想線で示す本来の弾性部４５ｂの形状と比べて撓んでいる。このようにＣ字状部材４５の弾性部４５ｂが筒状体４７に対して復元力を加えることにより、開閉蓋２３の回転速度を抑え、開閉蓋２３を全開位置で緩やかに停止させることができる。 At this time, as shown in FIG. 23B, the actual shape (shown by a solid line) of the elastic portion 45b is bent as compared with the original shape of the elastic portion 45b shown by a virtual line. Thus, the elastic part 45b of the C-shaped member 45 applies a restoring force to the cylindrical body 47, so that the rotation speed of the opening / closing lid 23 can be suppressed and the opening / closing lid 23 can be gently stopped at the fully opened position. .
　次に容器本体１１の取出口２４からウェットティッシュ４１を指で摘んで上方へ引っ張り出し、使用する。 Next, the wet tissue 41 is picked with a finger from the outlet 24 of the container body 11 and pulled upward to use.
　以上のように本実施の形態によれば、開閉蓋２３が全開となる前に、開閉蓋２３のＣ字状部材４５の弾性部４５ｂが、容器本体１１の筒状体４７の内面４７ｃに沿って移動しながら徐々に内方に撓む。これにより開閉蓋２３を少しずつ減速させることができ、全開位置で緩やかに停止させることができる。したがって、開閉蓋２３がストッパ３０に当接した後、開閉蓋２３が振動せず直ちに静止させることができる。 As described above, according to the present embodiment, before the opening / closing lid 23 is fully opened, the elastic portion 45b of the C-shaped member 45 of the opening / closing lid 23 is along the inner surface 47c of the cylindrical body 47 of the container body 11. Gradually inward while moving. Thereby, the opening / closing lid 23 can be decelerated little by little, and can be gently stopped at the fully opened position. Therefore, after the opening / closing lid 23 comes into contact with the stopper 30, the opening / closing lid 23 can be immediately stopped without vibrating.
　また本実施の形態によれば、開閉蓋２３を全開位置で緩やかに停止させるための機構が簡単である。すなわち、Ｃ字状部材４５は、開閉蓋２３と一体成形することができ、筒状体４７は、容器本体１１と一体成形することができるので、このような機構を低コストで容易に実現することができる。 Further, according to the present embodiment, the mechanism for gently stopping the open / close lid 23 at the fully open position is simple. That is, since the C-shaped member 45 can be integrally formed with the opening / closing lid 23 and the cylindrical body 47 can be integrally formed with the container body 11, such a mechanism can be easily realized at low cost. be able to.
　なお本実施の形態において、各筒状体４７は、容器本体１１の背側段部２５の側面から内側に向けて突出している。しかしながら、これに限らず、筒状体４７は、背側段部２５の側面内に形成された筒状の凹部からなっていてもよい。 In the present embodiment, each cylindrical body 47 protrudes inward from the side surface of the back side step portion 25 of the container body 11. However, the present invention is not limited thereto, and the cylindrical body 47 may be formed of a cylindrical recess formed in the side surface of the back side step portion 25.
　なお本実施の形態において、Ｃ字状部材４５および筒状体４７は、開閉蓋２３の両側部２３ｂ側に設けられているが、これに限らず、Ｃ字状部材４５および筒状体４７を一方の側部２３ｂ側のみに設けても良い。 In the present embodiment, the C-shaped member 45 and the cylindrical body 47 are provided on the both side portions 23b side of the opening / closing lid 23. However, the C-shaped member 45 and the cylindrical body 47 are not limited thereto. You may provide only in the one side part 23b side.
　第３の実施の形態
　以下、図面を参照して本発明の第３の実施の形態について説明する。図２４および図２５は本発明の第３の実施の形態を示す図である。図２４および図２５に示す第３の実施の形態は、スプリング体および制動部の構成が異なるものであり、他の構成は上述した第１の実施の形態と略同一である。図２４および図２５において、図１乃至図１８に示す第１の実施の形態と同一部分には同一の符号を付して詳細な説明は省略する。 Third Embodiment Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. 24 and 25 are views showing a third embodiment of the present invention. The third embodiment shown in FIGS. 24 and 25 is different in the structure of the spring body and the braking portion, and the other structure is substantially the same as the first embodiment described above. 24 and 25, the same parts as those of the first embodiment shown in FIGS. 1 to 18 are denoted by the same reference numerals, and detailed description thereof is omitted.
　図２４に示すように、開閉自在容器１０は、容器本体１１と、容器本体１１に揺動軸Ｘ－Ｘを中心に揺動自在に設けられた開閉蓋２３と、容器本体１１と開閉蓋２３との間に設けられた板ゴム（弾性部材）５０とを備えている。容器本体１１および開閉蓋２３の基本的な構成は、上述した図１乃至図５に示すものと略同様であり、ここでは説明を省略する。 As shown in FIG. 24, the openable / closable container 10 includes a container main body 11, an open / close lid 23 provided on the container main body 11 so as to be swingable about a swing axis XX, and the container main body 11 and the open / close lid 23. And a rubber plate (elastic member) 50 provided between the two. The basic configurations of the container body 11 and the opening / closing lid 23 are substantially the same as those shown in FIGS. 1 to 5 described above, and a description thereof is omitted here.
　図２４および図２５に示すように、開閉蓋２３の基端２３ａ側の両端に、それぞれ縦方向（揺動軸Ｘ－Ｘに対して垂直な方向）に延びる一対のスリット５２ａ、５２ｂが形成されている。また各一対のスリット５２ａ、５２ｂ間に、それぞれ舌片からなるスプリング体５３（以下舌片５３ともいう）が形成されている。すなわち各舌片５３は、開閉蓋２３の基端２３ａ側の両端にそれぞれ形成されている。 As shown in FIGS. 24 and 25, a pair of slits 52a and 52b extending in the vertical direction (direction perpendicular to the swing axis XX) are formed at both ends of the open / close lid 23 on the base end 23a side. ing. In addition, a spring body 53 (hereinafter also referred to as a tongue piece 53) formed of a tongue piece is formed between each pair of slits 52a and 52b. That is, the tongue pieces 53 are respectively formed at both ends of the open / close lid 23 on the base end 23a side.
　また図２５に示すように、開閉蓋２３の基端２３ａ側の両側部２３ｂに、それぞれ外側に向けて突出する円柱突起２６が設けられている。他方、容器本体１１の背側段部２５の両側面には、各円柱突起２６に対応する円形の挿入孔２９が形成されている。開閉蓋２３の各円柱突起２６を容器本体１１の各挿入孔２９に挿着することにより、開閉蓋２３が容器本体１１に対して揺動軸Ｘ－Ｘを中心に揺動自在に連結される。 As shown in FIG. 25, cylindrical protrusions 26 are provided on both side portions 23b on the base end 23a side of the opening / closing lid 23 so as to protrude outward. On the other hand, circular insertion holes 29 corresponding to the respective cylindrical protrusions 26 are formed on both side surfaces of the back side step portion 25 of the container body 11. By inserting each cylindrical projection 26 of the opening / closing lid 23 into each insertion hole 29 of the container body 11, the opening / closing lid 23 is connected to the container body 11 so as to be swingable about the swing axis XX. .
　また図２４および図２５には示していないが、背側段部２５にストッパ３０が設けられている。このストッパ３０は、開閉蓋２３が全開状態となった際、開閉蓋２３を所定位置に停止させるためのものである。 Although not shown in FIGS. 24 and 25, a stopper 30 is provided on the back side step portion 25. The stopper 30 is for stopping the opening / closing lid 23 at a predetermined position when the opening / closing lid 23 is fully opened.
　さらに、図２５に示すように、背側段部２５のうち少なくとも開閉蓋２３の舌片５３に対応する位置にスロープ部（制動部）５４が設けられている。このスロープ部５４は、開閉蓋２３を開位置から閉位置にもっていく際、舌片５３が当接して摺動するものである。 Further, as shown in FIG. 25, a slope portion (braking portion) 54 is provided at a position corresponding to at least the tongue piece 53 of the opening / closing lid 23 in the back side step portion 25. The slope portion 54 is a portion on which the tongue piece 53 comes into contact and slides when the opening / closing lid 23 is moved from the open position to the closed position.
　このスロープ部５４は、側面方向から見て、内方に向けて湾曲した弧状の内面５４ａを有している。また、スロープ部５４は、その内面５４ａと揺動軸Ｘ－Ｘとの間の距離が、開閉蓋２３が閉のときの状態から開のときの状態に向けて、徐々に狭まるように構成されている。 The slope portion 54 has an arc-shaped inner surface 54a that is curved inward as viewed from the side. Further, the slope portion 54 is configured such that the distance between the inner surface 54a and the swing axis XX gradually narrows from the closed state to the open state. ing.
　なお図２５は、開閉自在容器１０を正面側から見るとともに部分的に断面で示した斜視図であり、便宜上、開閉蓋２３を容器本体１１から取り外して示している。 FIG. 25 is a perspective view of the openable / closable container 10 as seen from the front side and partially shown in cross section. For convenience, the open / close lid 23 is removed from the container body 11.
　次にこのような構成からなる本実施の形態の作用について説明する。 Next, the operation of the present embodiment having such a configuration will be described.
　まずユーザーが操作ボタン５５を押圧することにより、係止片３２と爪部６６との係合が解除される（図１参照）。この場合、板ゴム５０の復元力により、開閉蓋２３が開となる。 First, when the user presses the operation button 55, the engagement between the locking piece 32 and the claw portion 66 is released (see FIG. 1). In this case, the opening / closing lid 23 is opened by the restoring force of the rubber plate 50.
　この際、開閉蓋２３は板ゴム５０に付勢され、揺動軸Ｘ－Ｘを中心に開方向（図２５に矢印で示す時計回り方向）に回動する。 At this time, the opening / closing lid 23 is urged by the rubber plate 50 and rotates in the opening direction (clockwise direction indicated by an arrow in FIG. 25) about the swing axis XX.
　この間、舌片５３とスロープ部５４との作用は以下のようになる。まず開閉蓋２３を全閉とした状態において、舌片５３は、容器本体１１の背側段部２５およびスロープ部５４から離れた位置にある。 During this time, the action of the tongue piece 53 and the slope portion 54 is as follows. First, in a state where the open / close lid 23 is fully closed, the tongue piece 53 is located away from the back side step portion 25 and the slope portion 54 of the container body 11.
　次に、開閉蓋２３が板ゴム５０の復元力により開方向に回動すると、これに伴って舌片５３もスロープ部５４側に移動し、舌片５３がスロープ部５４の内面５４ａに当接する。 Next, when the opening / closing lid 23 is rotated in the opening direction by the restoring force of the rubber plate 50, the tongue piece 53 is also moved to the slope portion 54 side, and the tongue piece 53 comes into contact with the inner surface 54a of the slope portion 54. .
　続いて開閉蓋２３が更に回動することにより、舌片５３は、スロープ部５４の内面５４ａに沿って全開点５４ｃに向けて上昇する。 Subsequently, when the opening / closing lid 23 further rotates, the tongue piece 53 ascends toward the full open point 54 c along the inner surface 54 a of the slope portion 54.
　この場合、スロープ部５４の内面５４ａと揺動軸Ｘ－Ｘとの間の距離は、下端部５４ｂから全開点５４ｃにかけて徐々に狭まっている。したがって、舌片５３は、スロープ部５４に沿って上昇するにしたがって徐々に撓んでいく。このように舌片５３が撓むことにより、板ゴム５０の付勢力に抗して、開閉蓋２３の回動速度が抑えられる。 In this case, the distance between the inner surface 54a of the slope portion 54 and the swing axis XX gradually decreases from the lower end portion 54b to the full open point 54c. Therefore, the tongue piece 53 is gradually bent as it rises along the slope portion 54. By bending the tongue piece 53 in this way, the rotational speed of the opening / closing lid 23 is suppressed against the urging force of the rubber plate 50.
　その後、開閉蓋２３が全開位置に達すると、開閉蓋２３の基端縁部２３ｄが図示しないストッパ３０に係止して開閉蓋２３が停止する。この際、舌片５３はスロープ部５４により撓まされた状態にある。このように舌片５３がスロープ部５４に対して復元力を加えることにより、開閉蓋２３の回転速度を抑え、開閉蓋２３を全開位置で緩やかに停止させることができる。 Thereafter, when the opening / closing lid 23 reaches the fully open position, the base end edge 23d of the opening / closing lid 23 is locked to a stopper 30 (not shown), and the opening / closing lid 23 stops. At this time, the tongue piece 53 is bent by the slope portion 54. Thus, when the tongue piece 53 applies a restoring force to the slope portion 54, the rotation speed of the opening / closing lid 23 can be suppressed, and the opening / closing lid 23 can be gently stopped at the fully opened position.
　次に容器本体１１の取出口２４からウェットティッシュ４１を指で摘んで上方へ引っ張り出し、使用する。 Next, the wet tissue 41 is picked with a finger from the outlet 24 of the container body 11 and pulled upward to use.
　以上のように本実施の形態によれば、開閉蓋２３が全開となる前に、開閉蓋２３の舌片５３が、容器本体１１のスロープ部（制動部）５４の内面５４ａに沿って徐々に撓む。これにより開閉蓋２３を少しずつ減速させることができ、全開位置で緩やかに停止させることができる。したがって、開閉蓋２３がストッパ３０に係止した後、開閉蓋２３を振動させずに直ちに静止させることができる。 As described above, according to the present embodiment, before the opening / closing lid 23 is fully opened, the tongue piece 53 of the opening / closing lid 23 gradually moves along the inner surface 54a of the slope portion (braking portion) 54 of the container body 11. Bend. Thereby, the opening / closing lid 23 can be decelerated little by little, and can be gently stopped at the fully opened position. Therefore, after the opening / closing lid 23 is locked to the stopper 30, the opening / closing lid 23 can be immediately stopped without vibrating.
　また本実施の形態によれば、開閉蓋２３を全開位置で緩やかに停止させるための機構が簡単である。すなわち、舌片５３は、開閉蓋２３と一体成形することができ、スロープ部５４は、容器本体１１と一体成形することができるので、このような機構を低コストで容易に実現することができる。 Further, according to the present embodiment, the mechanism for gently stopping the open / close lid 23 at the fully open position is simple. That is, since the tongue piece 53 can be integrally formed with the opening / closing lid 23 and the slope portion 54 can be integrally formed with the container body 11, such a mechanism can be easily realized at low cost. .
　なお上述した本実施の形態において、舌片５３は開閉蓋２３の両側に設けられているが、これに限らず、舌片５３を開閉蓋２３の一箇所にのみ設けても良い。 In the above-described embodiment, the tongue pieces 53 are provided on both sides of the opening / closing lid 23. However, the present invention is not limited to this, and the tongue pieces 53 may be provided only at one location of the opening / closing lid 23.
　第４の実施の形態
　以下、図面を参照して本発明の第４の実施の形態について説明する。図２６および図２７は本発明の第４の実施の形態を示す図である。図２６および図２７に示す第４の実施の形態は、スプリング体およびストッパ部の構成が異なるものであり、他の構成は上述した第１の実施の形態と略同一である。図２６および図２７において、図１乃至図１８に示す第１の実施の形態と同一部分には同一の符号を付して詳細な説明は省略する。 Fourth Embodiment Hereinafter, a fourth embodiment of the present invention will be described with reference to the drawings. 26 and 27 are diagrams showing a fourth embodiment of the present invention. The fourth embodiment shown in FIGS. 26 and 27 is different in the configuration of the spring body and the stopper portion, and the other configurations are substantially the same as those of the first embodiment described above. 26 and 27, the same parts as those of the first embodiment shown in FIGS. 1 to 18 are denoted by the same reference numerals, and detailed description thereof is omitted.
　図２６に示すように、開閉自在容器１０は、容器本体１１と、容器本体１１に揺動軸Ｘ－Ｘを中心に揺動自在に設けられた開閉蓋２３と、容器本体１１と開閉蓋２３との間に設けられた板ゴム（弾性部材）５０とを備えている。容器本体１１および開閉蓋２３の基本的な構成は、上述した図１乃至図５に示すものと同様であり、ここでは説明を省略する。 As shown in FIG. 26, the openable / closable container 10 includes a container body 11, an opening / closing lid 23 provided on the container body 11 so as to be swingable about a swing axis XX, and the container body 11 and the opening / closing lid 23. And a rubber plate (elastic member) 50 provided between the two. The basic configuration of the container body 11 and the opening / closing lid 23 is the same as that shown in FIGS.
　図２６および図２７に示すように、開閉蓋２３の基端２３ａ側の両端に、それぞれＬ字形状のスリット６１が形成されている。またＬ字形状のスリット６１に沿って、横方向（揺動軸Ｘ－Ｘに平行な方向）に延びる側片からなるスプリング体６２（以下側片６２ともいう）が形成されている。すなわち各側片６２は、それぞれ開閉蓋２３の基端縁部２３ｄに沿って水平に延び、開閉蓋２３の両側部２３ｂ側に向けて突出するとともに、弾力性（バネ性）を有している。 As shown in FIGS. 26 and 27, L-shaped slits 61 are formed at both ends of the open / close lid 23 on the base end 23a side. A spring body 62 (hereinafter also referred to as a side piece 62) is formed along the L-shaped slit 61. The spring body 62 is a side piece extending in the lateral direction (direction parallel to the swing axis XX). That is, each side piece 62 extends horizontally along the base end edge 23d of the open / close lid 23, protrudes toward the both side portions 23b of the open / close lid 23, and has elasticity (springiness). .
　図２７に示すように、開閉蓋２３の基端２３ａ側の両側部２３ｂに、それぞれ外側に向けて突出する円柱突起２６が設けられている。他方、容器本体１１の背側段部２５の両側面には、各円柱突起２６に対応する円形の挿入孔２９が形成されている。開閉蓋２３の各円柱突起２６を容器本体１１の各挿入孔２９に挿着することにより、開閉蓋２３が容器本体１１に対して揺動軸Ｘ－Ｘを中心に揺動自在に連結される。 As shown in FIG. 27, cylindrical protrusions 26 are provided on both side portions 23b on the base end 23a side of the opening / closing lid 23 so as to protrude outward. On the other hand, circular insertion holes 29 corresponding to the respective cylindrical protrusions 26 are formed on both side surfaces of the back side step portion 25 of the container body 11. By inserting each cylindrical projection 26 of the opening / closing lid 23 into each insertion hole 29 of the container body 11, the opening / closing lid 23 is connected to the container body 11 so as to be swingable about the swing axis XX. .
　また図２７に示すように、容器本体１１の背側段部２５上であって、各側片６２に対応する位置に、それぞれ断面逆Ｌ字形状を有するストッパ部６３が設けられている。このストッパ部６３は、開閉蓋２３が全開状態となった際、側片６２が弾性的に当接することにより開閉蓋２３の開きを停止させるためのものである。 Further, as shown in FIG. 27, stopper portions 63 each having an inverted L-shaped cross section are provided on the back side step portion 25 of the container body 11 and at positions corresponding to the side pieces 62. The stopper portion 63 is for stopping the opening of the opening / closing lid 23 by the elastic contact of the side piece 62 when the opening / closing lid 23 is fully opened.
　次にこのような構成からなる本実施の形態の作用について説明する。 Next, the operation of the present embodiment having such a configuration will be described.
　まずユーザーが操作ボタン５５を押圧することにより、係止片３２と爪部６６との係合が解除される（図１参照）。この場合、板ゴム５０の復元力により、開閉蓋２３が開となる。 First, when the user presses the operation button 55, the engagement between the locking piece 32 and the claw portion 66 is released (see FIG. 1). In this case, the opening / closing lid 23 is opened by the restoring force of the rubber plate 50.
　この際、開閉蓋２３は板ゴム５０に付勢され、揺動軸Ｘ－Ｘを中心に開方向（図２７に矢印で示す方向）に回動する。 At this time, the opening / closing lid 23 is urged by the rubber plate 50 and rotates in the opening direction (the direction indicated by the arrow in FIG. 27) about the swing axis XX.
　その後、開閉蓋２３が全開位置に達すると、開閉蓋２３の側片６２がストッパ部６３に当接して開閉蓋２３が停止する。この場合、側片６２がバネ性を有しているため、側片６２がストッパ部６３に弾性的に当接する。 Thereafter, when the opening / closing lid 23 reaches the fully opened position, the side piece 62 of the opening / closing lid 23 comes into contact with the stopper portion 63 and the opening / closing lid 23 stops. In this case, since the side piece 62 has a spring property, the side piece 62 elastically contacts the stopper portion 63.
　このように側片６２がストッパ部６３に対して弾性的に当接することにより、側片６２はショックアブソーバーとしての役割を果たす。これにより、開閉蓋２３を全開位置で緩やかに停止させることができる。 Thus, the side piece 62 plays a role as a shock absorber by elastically abutting the side piece 62 against the stopper portion 63. Thereby, the open / close lid 23 can be gently stopped at the fully opened position.
　次に容器本体１１の取出口２４からウェットティッシュ４１を指で摘んで上方へ引っ張り出し、使用する。 Next, the wet tissue 41 is picked with a finger from the outlet 24 of the container body 11 and pulled upward to use.
　以上のように本実施の形態によれば、スプリング体（側片）６２がストッパ部６３に対して弾性的に当接して開閉蓋２３が衝突する衝撃を吸収する。これにより、開閉蓋２３を全開位置で緩やかに停止させることができる。したがって、開閉蓋２３がストッパ部６３に係止した後、開閉蓋２３を振動させずに直ちに静止させることができる。 As described above, according to the present embodiment, the spring body (side piece) 62 elastically abuts against the stopper portion 63 to absorb the impact of collision of the opening / closing lid 23. Thereby, the open / close lid 23 can be gently stopped at the fully opened position. Therefore, after the opening / closing lid 23 is locked to the stopper portion 63, the opening / closing lid 23 can be immediately stopped without vibrating.
　また本実施の形態によれば、開閉蓋２３を全開位置で緩やかに停止させるための機構が簡単である。すなわち、側片６２は、開閉蓋２３と一体成形することができ、ストッパ部６３は、容器本体１１と一体成形することができるので、このような機構を低コストで容易に実現することができる。 Further, according to the present embodiment, the mechanism for gently stopping the open / close lid 23 at the fully open position is simple. That is, the side piece 62 can be integrally formed with the opening / closing lid 23, and the stopper portion 63 can be integrally formed with the container body 11. Therefore, such a mechanism can be easily realized at low cost. .
　なお上述した本実施の形態において、側片６２およびストッパ部６３は開閉蓋２３の両側に設けられているが、これに限らず、側片６２およびストッパ部６３を開閉蓋２３の一側のみに設けても良い。 In the above-described embodiment, the side piece 62 and the stopper portion 63 are provided on both sides of the opening / closing lid 23. However, the present invention is not limited thereto, and the side piece 62 and the stopper portion 63 are provided only on one side of the opening / closing lid 23. It may be provided.
