Description

本発明は、容器の開蓋装置に係り、詳しくはペットボトル等の開口部を閉塞するねじ蓋を開くための開蓋装置に関する。   The present invention relates to a container opening device, and more particularly to a lid opening device for opening a screw lid that closes an opening of a plastic bottle or the like.

ねじ蓋によって開口部が閉塞された飲料用容器（ペットボトル等）では、一般的に使用者は、一方の手で容器本体を把持し、他方の手でねじ蓋を回転させ、ねじ蓋を容器本体から取り去る。すなわち、使用者は両手を使って飲料用容器のねじ蓋を開く。未開封の飲料用容器にはねじ蓋にタンパーエビデントバンドを備えたものがあり、ねじ蓋を容器本体から取り去るには、比較的大きな力を必要とする。そのため、片手で容器本体を把持し、親指でキャップを回転させる等して、片手で飲料用容器のねじ蓋を取り去ることは難しい。   In a beverage container (such as a plastic bottle) whose opening is closed by a screw lid, the user generally holds the container body with one hand, rotates the screw lid with the other hand, Remove from the body. That is, the user uses both hands to open the screw lid of the beverage container. Some unopened beverage containers are provided with a tamper evidence band on the screw lid, and a relatively large force is required to remove the screw lid from the container body. For this reason, it is difficult to remove the screw lid of the beverage container with one hand by holding the container body with one hand and rotating the cap with the thumb.

ねじ蓋を備えた容器の開蓋装置としては、壁等に固定された固定アームと、固定アームの一端に揺動自在に支持された揺動アームと備え、固定アームと揺動アームとの間にねじ蓋を挟持するようにしたものがある（例えば、特許文献１）。   A container opening device provided with a screw lid includes a fixed arm fixed to a wall or the like, and a swing arm supported swingably at one end of the fixed arm, between the fixed arm and the swing arm. There is one in which a screw lid is clamped (for example, Patent Document 1).

The base portion 61L, the cylindrical portion clamping portion 63L, and the top contact portion 64L are formed to be thicker than the elastic portion 68L, and the relative positional relationship among the base portion 61L, the cylindrical portion clamping portion 63L, and the top contact portion 64L changes. It has a predetermined rigidity so that it does not. On the other hand, the elastic portion 68L is formed to a thickness that allows elastic deformation.

左側回動部材２２Ｌおよび右側回動部材２２Ｒは、嵌め込みによってハウジング２１に組み付けられる。最初に、左側回動部材２２Ｌの弾性部６８Ｌがハウジング２１の底板２４と相対するように配置し、左側回動部材２２Ｌの２つの軸部６２Ｌをガイド溝４１，４６に遊嵌させる。この状態から、左側回動部材２２Ｌを底板２４側に押し込むと、軸部６２Ｌおよび側板２６，２８が撓み、２つの軸部６２Ｌがそれぞれ第１支持孔３６および第３支持孔４４に嵌合する。これにより、左側回動部材２２Ｌは、軸部６２Ｌの中心を回転中心としてハウジング２１に回動自在に支持される。同様に、右側回動部材２２Ｒは、軸部６２Ｒが第２支持孔３７および第４支持孔４５に嵌合し、軸部６２Ｒの中心を回転中心としてハウジング２１に回動自在に支持される。   The left turning member 22L and the right turning member 22R are assembled to the housing 21 by fitting. First, the elastic portion 68L of the left rotation member 22L is disposed so as to face the bottom plate 24 of the housing 21, and the two shaft portions 62L of the left rotation member 22L are loosely fitted in the guide grooves 41 and 46. When the left rotation member 22L is pushed into the bottom plate 24 from this state, the shaft portion 62L and the side plates 26 and 28 are bent, and the two shaft portions 62L are fitted into the first support hole 36 and the third support hole 44, respectively. . Thereby, the left rotation member 22L is rotatably supported by the housing 21 with the center of the shaft portion 62L as the rotation center. Similarly, the shaft portion 62R is fitted in the second support hole 37 and the fourth support hole 45, and the right rotation member 22R is rotatably supported by the housing 21 with the center of the shaft portion 62R as the rotation center.

左側回動部材２２Ｌおよび右側回動部材２２Ｒの回転方向は、左右の筒部挟持部６３Ｌ，６３Ｒが底板２４に近接する向きの回転方向を第１の回転方向とし、その逆方向、すなわち左側筒部挟持部６３Ｌが側板２５に近接し、右側筒部挟持部６３Ｒが側板２７に近接する向きの回転方向を第２の回転方向とする。   Regarding the rotation direction of the left rotation member 22L and the right rotation member 22R, the rotation direction in which the left and right tube portion clamping portions 63L and 63R are close to the bottom plate 24 is the first rotation direction, and the opposite direction, that is, the left tube A rotation direction in which the portion clamping portion 63L is close to the side plate 25 and the right cylinder portion clamping portion 63R is close to the side plate 27 is defined as a second rotation direction.

左右の回動部材２２Ｌ，２２Ｒがハウジング２１に支持された状態で、左右の弾性部６８Ｌ，６８Ｒは、その先端が***部５１，５２に当接し、弾性変形させられる。そのため、左右の回動部材２２Ｌ，２２Ｒは、弾性部６８Ｌ，６８Ｒの復元力を受けて、それぞれ第２の回転方向に付勢されている。これにより、左側回動部材２２Ｌは、基部６１Ｌの突部７１Ｌが側板２５に当接し、右側回動部材２２Ｒは、基部６１Ｒの突部７１Ｒが側板２７に当接した状態となる。また、左右の回動部材２２Ｌ，２２Ｒは、基部６１Ｌ，６１Ｒの前後端面の突部７２Ｌ，７２Ｒを介して側板２６，２８と摺接している。   In a state where the left and right rotating members 22L and 22R are supported by the housing 21, the distal ends of the left and right elastic portions 68L and 68R abut against the raised portions 51 and 52 and are elastically deformed. Therefore, the left and right rotating members 22L and 22R are biased in the second rotational direction by receiving the restoring force of the elastic portions 68L and 68R, respectively. Thereby, the left rotation member 22L is in a state in which the protrusion 71L of the base 61L contacts the side plate 25, and the right rotation member 22R is in the state where the protrusion 71R of the base 61R contacts the side plate 27. Further, the left and right rotating members 22L and 22R are in sliding contact with the side plates 26 and 28 via the protrusions 72L and 72R on the front and rear end surfaces of the base portions 61L and 61R.

以上のようにハウジング２１、左側回動部材２２Ｌ、右側回動部材２２Ｒを組み合わせることによって、図１に示す開蓋装置２０が構成される。この状態で、左側回動部材２２Ｌの筒部挟持部６３Ｌの先端面６６Ｌと、右側回動部材２２Ｒの筒部挟持部６３Ｒの先端面６６Ｒと、側板２６と、側板２８とによって、ねじ蓋１２が挿通可能な開口７５が画成される。初期状態では、左右の弾性部６８Ｌ，６８Ｒに付勢力によって、左右の筒部挟持部６３Ｌ，６３Ｒが互いに最も離間し、開口７５が最も開かれた状態となっている。   As described above, the lid opening device 20 shown in FIG. 1 is configured by combining the housing 21, the left rotation member 22L, and the right rotation member 22R. In this state, the screw lid 12 is formed by the distal end surface 66L of the cylindrical portion clamping portion 63L of the left rotation member 22L, the distal end surface 66R of the cylindrical portion clamping portion 63R of the right rotation member 22R, the side plate 26, and the side plate 28. An opening 75 through which can be inserted is defined. In the initial state, the left and right tube portion clamping portions 63L and 63R are separated from each other by the biasing force of the left and right elastic portions 68L and 68R, and the opening 75 is most opened.

次に、第１実施形態に係る開蓋装置２０の使用方法および使用時の作動態様について説明する。開蓋装置２０は、使用者に対して静止した状態を維持することができる壁や天井に取り付けられる。本実施形態では、開蓋装置２０を自動車のダッシュボード８０に取り付けた例について説明する。なお、開蓋装置２０は、自動車のルーフライニングやドアライニング、サイドライニング、飲料水の自動販売機の本体壁面、戸棚の壁面等に取り付けてもよい。   Next, the usage method of the lid opening apparatus 20 which concerns on 1st Embodiment, and the operation | movement aspect at the time of use are demonstrated. The lid opening device 20 is attached to a wall or ceiling that can maintain a stationary state with respect to the user. This embodiment demonstrates the example which attached the lid opening apparatus 20 to the dashboard 80 of the motor vehicle. The lid opening device 20 may be attached to a roof lining, door lining, side lining of an automobile, a main body wall surface of a drinking water vending machine, a wall surface of a cupboard, or the like.

図４に示すように、ダッシュボード８０には、開蓋装置２０のフランジ部３１，３２の貫通孔３３，３４に対応する位置に２つの貫通孔８１が形成されている。貫通孔３３および貫通孔８１と、貫通孔３４および貫通孔８１とには、それぞれボルト９１が挿通され、ボルト９１にはナット９２が螺着される。これらのボルト９１およびナット９２によって、開蓋装置２０はダッシュボード８０に締結される。なお、ボルト９１およびナット９２に代えて、締結クリップやリベット等で開蓋装置２０とダッシュボード８０との締結を行ってもよい。   As shown in FIG. 4, two through holes 81 are formed in the dashboard 80 at positions corresponding to the through holes 33 and 34 of the flange portions 31 and 32 of the lid opening device 20. Bolts 91 are respectively inserted into the through holes 33 and 81, and the through holes 34 and 81, and nuts 92 are screwed into the bolts 91. The lid opening device 20 is fastened to the dashboard 80 by these bolts 91 and nuts 92. Instead of the bolt 91 and the nut 92, the lid opening device 20 and the dashboard 80 may be fastened with fastening clips, rivets, or the like.

図４に示すように、最初に、使用者は、ねじ蓋１２が開口部１３に螺着された容器本体１１を把持し、ねじ蓋１２を頂部１８側から開蓋装置２０の開口７５を通して底板２４側へと挿入する。ねじ蓋１２の開蓋装置２０に対する挿入が進むと、ねじ蓋１２の頂部１８が左右の頂部当接部６４Ｌ，６４Ｒの先端部に当接する。この状態から、ねじ蓋１２を底板２４側へと更に挿入すると、左右の回動部材２２Ｌ，２２Ｒが、それぞれ弾性部６８Ｌ，６８Ｒの付勢力に抗して、弾性部６８Ｌ，６８Ｒを撓ませつつ、第１の回転方向に回動される。   As shown in FIG. 4, first, the user grasps the container body 11 in which the screw lid 12 is screwed into the opening 13, and the screw lid 12 is passed through the opening 75 of the lid opening device 20 from the top 18 side. Insert to 24 side. When the insertion of the screw lid 12 into the lid opening device 20 proceeds, the top portion 18 of the screw lid 12 comes into contact with the tip portions of the left and right top contact portions 64L and 64R. When the screw cover 12 is further inserted into the bottom plate 24 from this state, the left and right rotating members 22L and 22R are deflecting the elastic portions 68L and 68R against the urging forces of the elastic portions 68L and 68R, respectively. And rotated in the first rotation direction.

図５に示すように、左右の回動部材２２Ｌ，２２Ｒが第１の回転方向に回動すると、左右の筒部挟持部６３Ｌ，６３Ｒ間の距離が短くなり、その先端面６６Ｌ，６６Ｒがねじ蓋１２の筒部１７の外周面に当接する。このとき、各先端面６６Ｌ，６６Ｒに形成された突条６７Ｌ，６７Ｒがねじ蓋１２の縦溝１９に噛み合う。ねじ蓋１２が底板２４に近接し、頂部１８が頂部当接部６４Ｌ，６４Ｒを底板２４側に変位させるほど、回動部材２２Ｌ，２２Ｒを第１の回転方向に回動させる力が大きくなり、左右の筒部挟持部６３Ｌ，６３Ｒが筒部１７を挟み込む力が大きくなる。ここで、図４および図５に示すように、軸部６２Ｌ（６２Ｒ）の中心と頂部当接部６４Ｌ（６４Ｒ）の頂部１８が当接する部分との間の直線距離が、軸部６２Ｌ（６２Ｒ）の中心と筒部挟持部６３Ｌ（６３Ｒ）の筒部１７と当接する部分との間の直線距離よりも長いため、てこの原理によって左右の筒部挟持部６３Ｌ，６３Ｒに加わる挟持力が高められている。この場合、軸部６２Ｌ（６２Ｒ）は支点、頂部当接部６４Ｌ（６４Ｒ）の頂部１８が当接する部分は力点、筒部挟持部６３Ｌ（６３Ｒ）の筒部１７と当接する部分は作用点となる。ねじ蓋１２の開蓋装置２０に対する挿入は、頂部１８が挿入規制片５３，５４に当接した時点で完了する。   As shown in FIG. 5, when the left and right turning members 22L and 22R are turned in the first rotation direction, the distance between the left and right tube portion clamping portions 63L and 63R is shortened, and the tip surfaces 66L and 66R are screwed. It contacts the outer peripheral surface of the cylindrical portion 17 of the lid 12. At this time, the protrusions 67L and 67R formed on the respective end faces 66L and 66R mesh with the vertical groove 19 of the screw lid 12. As the screw lid 12 approaches the bottom plate 24 and the top portion 18 displaces the top contact portions 64L and 64R toward the bottom plate 24, the force for rotating the rotating members 22L and 22R in the first rotation direction increases. The force with which the left and right tube portion holding portions 63L and 63R pinch the tube portion 17 is increased. Here, as shown in FIGS. 4 and 5, the linear distance between the center of the shaft portion 62L (62R) and the portion where the top portion 18 of the top contact portion 64L (64R) contacts is the shaft portion 62L (62R). ) And the linear distance between the cylindrical portion clamping portion 63L (63R) and the portion of the cylindrical portion clamping portion 63L (63R) in contact with the cylindrical portion 17, the clamping force applied to the left and right cylindrical portion clamping portions 63L and 63R is increased by the lever principle. It has been. In this case, the shaft portion 62L (62R) is a fulcrum, the portion where the apex portion 18 of the apex abutment portion 64L (64R) abuts is the power point, and the portion abutting the tube portion 17 of the tube portion clamping portion 63L (63R) is the action point. Become. Insertion of the screw lid 12 into the lid opening device 20 is completed when the top 18 comes into contact with the insertion restricting pieces 53 and 54.

ねじ蓋１２の開蓋装置２０に対する挿入が完了した状態で、ねじ蓋１２は左右の筒部挟持部６３Ｌ，６３Ｒに挟持され、開蓋装置２０に固定された状態となる。使用者は、この状態で、容器本体１１を容器本体１１（開口部１３）の軸線回りであって、雄ねじ部１４と雌ねじ部１６の螺合を解除させる方向に回転させると、容器本体１１とねじ蓋１２とが相対回転し、雄ねじ部１４と雌ねじ部１６との螺合を緩めることができる。   In a state where the insertion of the screw lid 12 into the lid opening device 20 is completed, the screw lid 12 is sandwiched between the left and right tube portion clamping portions 63L and 63R and is fixed to the lid opening device 20. In this state, when the user rotates the container main body 11 around the axis of the container main body 11 (opening 13) and releases the screwing of the male screw part 14 and the female screw part 16, the container main body 11 The screw lid 12 rotates relative to each other, and the screwing between the male screw portion 14 and the female screw portion 16 can be loosened.

使用者が、容器本体１１を把持し、開口部１３に緩く螺合したねじ蓋１２を開蓋装置２０から引き出すと、頂部１８による頂部当接部６４Ｌ，６４Ｒに加わる力が消失し、左右の回動部材２２Ｌ，２２Ｒは弾性部６８Ｌ，６８Ｒに付勢されて初期状態に復帰する（図４に示す状態）。   When the user grips the container body 11 and pulls the screw lid 12 loosely screwed into the opening 13 from the opening device 20, the force applied to the top contact portions 64L and 64R by the top 18 disappears, and the left and right The rotating members 22L and 22R are urged by the elastic portions 68L and 68R to return to the initial state (the state shown in FIG. 4).

第１実施形態に係る開蓋装置２０によれば、使用者は片手で容器本体１１に螺着されたねじ蓋１２の螺合を緩めることができる。容器本体１１に対するねじ蓋１２の螺合が緩められると、使用者は比較的容易にねじ蓋１２を容器本体１１から片手で取り去ることができる。例えば、手のひらと、中指、薬指、小指で容器本体１１を把持し、親指でねじ蓋１２を回転させ、親指と人差し指とでねじ蓋１２を開口部１３から取り去ることができる。   According to the lid opening device 20 according to the first embodiment, the user can loosen the screw lid 12 screwed to the container body 11 with one hand. When the screw lid 12 is loosened from the container body 11, the user can remove the screw lid 12 from the container body 11 with one hand relatively easily. For example, the container body 11 can be grasped with the palm, middle finger, ring finger, and little finger, the screw lid 12 can be rotated with the thumb, and the screw lid 12 can be removed from the opening 13 with the thumb and forefinger.

使用者が、自らの両手を用いて容器本体１１に螺着されたねじ蓋１２を緩めようとする際には、ねじ蓋１２を把持するために比較的な大きな力が必要となる。開蓋装置２０は、ねじ蓋１２を保持することによって、使用者によるねじ蓋１２の把持を省くため、使用者は開蓋操作が容易になる。また、使用者は、ねじ蓋１２をハウジング２１の受容孔２９（開口７５）に挿入するだけで、ねじ蓋１２を開蓋装置２０に保持させることができ、開蓋操作が容易である。   When the user tries to loosen the screw lid 12 screwed to the container body 11 with his / her hands, a relatively large force is required to grip the screw lid 12. Since the lid opening device 20 holds the screw lid 12, the user does not need to hold the screw lid 12, so that the user can easily perform the lid opening operation. Moreover, the user can hold the screw lid 12 on the lid opening device 20 simply by inserting the screw lid 12 into the receiving hole 29 (opening 75) of the housing 21, and the lid opening operation is easy.
