Description

本願発明は、例えば液体調味料や食用油等の液体を包装する容器（瓶、ボトル）に使用する合成樹脂製の蓋装置に関するものである。   The present invention relates to a synthetic resin lid device used for containers (bottles, bottles) for packaging liquids such as liquid seasonings and edible oils.

この種の蓋装置は、容器の口部に強制嵌合によって取付け（嵌着）される本体と、この本体を上方から塞ぐキャップとを備えており、本体とキャップとが別体になっていてキャップがねじ蓋方式になっているものと、キャップがヒンジを介して本体に一体に繋がっているタイプとがあり、ヒンジキャップ方式の蓋装置では、キャップのうち軸心を挟んでヒンジと反対側の自由端部に、開き操作に際して指を掛ける摘まみ片を突設している。   This type of lid device includes a main body that is attached (fitted) to the mouth of the container by forced fitting, and a cap that closes the main body from above, and the main body and the cap are separated. There are caps with screw caps and caps that are integrally connected to the main body via hinges. In hinge cap caps, on the opposite side of the cap from the hinge with the shaft centered At the free end of the knob, a knob piece for projecting a finger in the opening operation is provided.

そして、ヒンジキャップ方式の蓋装置において、流通段階で不正開封された場合にその事実を視認できる手段、或いは、幼児が開けて事故が発生することを防止する手段を講じることが提案されている。その例として特許文献１では、キャップのうち摘まみ片の付け根箇所に下向き鉤状の突片を設ける一方、本体のうち軸心を挟んでヒンジと反対側に位置した部位に、弾性変形によって前記突片が嵌入する帯片を形成している。この特許文献１では、キャップを開くと帯片又は突片が破断する。   In the hinge cap type lid device, it has been proposed to take a means for visually confirming the fact that it is illegally opened in the distribution stage, or a means for preventing an accident from occurring when an infant opens. As an example, in Patent Document 1, a downward hook-like protrusion is provided at the base of the knob piece of the cap, while the portion of the main body located on the opposite side of the hinge across the shaft center is elastically deformed. A strip into which the projecting piece is inserted is formed. In Patent Document 1, when the cap is opened, the strip or the projecting piece is broken.

また、特許文献２では、本体のうち軸心を挟んでヒンジと反対側の部位に、閉じた状態でのキャップの摘まみ片を囲う上向き開口の壁体を形成し、この壁体に、弾性変形によってキャップの摘まみ片が入り込むフランジを形成した構成が記載されている。この特許文献２では、壁体に設けた帯片を切り裂くとフランジも一緒に引き千切られて、キャップを開けることができる。
実公平２−２１４０６号公報 特公平４−３６９４６号公報 Moreover, in patent document 2, the wall body of the upward opening which encloses the knob | pick piece of the cap in the closed state is formed in the part on the opposite side to the hinge across the axis of the main body, and the wall body is elastic. A configuration is described in which a flange into which the tab of the cap enters is formed by deformation. In Patent Document 2, when the strip provided on the wall body is torn, the flange is also torn together and the cap can be opened.
Japanese Utility Model Publication No. 2-21406 Japanese Patent Publication No. 4-36946

特許文献１の構成は構造は簡単であるが、突片及び帯片は摘まみ片で隠れているため、不正開封されてもその事実を簡単に発見しにくいという問題があった。また、摘まみ片に指を掛けて開封するに際して突片と帯片との係合が抵抗として作用するが、突片と帯片との存在が分かりにくいことから、開封に異常に力が掛かることに対して消費者に不快感を与える虞もあった。   Although the structure of Patent Document 1 has a simple structure, there is a problem in that it is difficult to easily find the fact even if the tamper pieces are tampered with because the protruding pieces and the strips are hidden by the knobs. In addition, the engagement between the projecting piece and the strip acts as a resistance when opening the pick piece with a finger, but since the existence of the projecting piece and the strip is difficult to understand, an abnormal force is applied to the opening. On the other hand, there is a possibility that the consumer is uncomfortable.

他方、特許文献２では帯片は摘まみ片の外側に露出しているため不正開封されるとその事実を即座に視認でき、また、帯片を引き裂くとキャップは簡単に開くことができるため、消費者に不快感を与えることもないと言える。しかし、構造が複雑であるため製造用金型の加工コストが嵩むという問題や、帯片を引き裂いた後に壁体が本体に残ったままであるため、開封後にキャップの摘まみ片に指をかけにくい（すなわち開けにくい）という問題があった。   On the other hand, in Patent Document 2, since the strip is exposed to the outside of the pick piece, the fact can be immediately recognized when tampered, and the cap can be easily opened by tearing the strip. It can be said that there is no discomfort to consumers. However, since the structure is complicated, the processing cost of the manufacturing mold is increased, and the wall remains on the main body after tearing the strip, so it is difficult to put fingers on the tab of the cap after opening. (I.e. difficult to open).

本願発明は、このような実情に鑑みなされたもので、不正開封発覚機能を有する蓋装置において、より改良されたものを提供することを課題とするのものである。   This invention is made | formed in view of such a situation, and makes it a subject to provide the improved thing in the lid | cover apparatus which has an unauthorized opening detection function.

本願発明は、容器の口部に強制嵌合で取付けられる本体と、屈曲自在なヒンジを介して前記本体に一体に設けたキャップとを備えており、前記本体には、注出口とプルオープン式の閉鎖板とを設けている一方、前記キャップのうち軸心を挟んでヒンジと反対側の自由端部に摘まみ片を突設しており、前記キャップを開けると前記注出口が露出し、前記キャップを閉じるとその下面が前記本体に形成された段部に重なるようになっている液体容器用の合成樹脂製の蓋装置であって、前記本体のうち軸心を挟んでヒンジと反対側の部位に、閉じた状態でのキャップの摘まみ片を上方及び左右両側から囲うと共に本体から除去又は引き起こし可能な係止部を、当該係止部の弾性変形によって前記摘まみ片が嵌まり込むように形成しており、更に、前記係止部は、前記本体の外周面から外向きにはみ出た水平部と、前記水平部の外縁から立ち上がった壁部とを備えており、前記水平部は前記段部と同じ高さになっていると共に、前記水平部が千切り可能なブリッジ部を介して前記本体に繋がっており、更に、前記壁部に、前記キャップの摘まみ片が嵌まり係合する窓穴を、前記水平部まで広がるように形成している。 The present invention includes a main body that is attached to the mouth of the container by forced fitting, and a cap that is provided integrally with the main body via a bendable hinge. The main body includes a spout and a pull-open type. The closure plate is provided, and a pinch piece is projected from the free end on the opposite side of the hinge across the axis of the cap, and the spout is exposed when the cap is opened , A lid device made of synthetic resin for a liquid container whose lower surface overlaps with a step portion formed on the main body when the cap is closed, the side of the main body opposite to the hinge across the axis In the part of the cap, the tab of the cap in the closed state is enclosed from above and from the left and right sides, and the locking portion that can be removed or caused from the main body is fitted into the tab by elastic deformation of the locking portion. In addition, the front The locking portion includes a horizontal portion protruding outward from the outer peripheral surface of said body comprises a wall portion which rises from an outer edge of the horizontal portion, the horizontal portion is the same height as the step portion In addition, the horizontal portion is connected to the main body through a bridge portion that can be shredded, and further, a window hole that engages and engages with a knob piece of the cap on the wall portion extends to the horizontal portion. It is formed as follows.

本願発明において、ブリッジ部をひき千切ることで係止部を本体から除去するか引き起こすかしてキャップの摘まみ片と係止部との係合状態を解除しないとキャップを開けることはできず、この機能は特許文献１，２と同様である。そして、本願発明では、キャップの摘まみ片が係止部で囲われていることから、不正開封があるとその事実を即座に視認することができる。 In the present invention, it is impossible to open the cap unless the engagement state between the cap tab and the engaging portion is released by removing or causing the engaging portion by removing the bridge portion from the main body. This function is the same as in Patent Documents 1 and 2. And in this invention, since the knob | pick piece of a cap is enclosed by the latching | locking part, if there exists unauthorized opening, the fact can be visually recognized immediately.

また、係止部を除去したり引き起こしたりすることによってキャップの摘まみ片はその全体が露出するため、簡単に開封することができる。また、特許文献２のような囲い壁は不要であるため構造も簡単であり、このため金型の加工コストが嵩むこともない。   Moreover, since the whole picking piece of the cap is exposed by removing or causing the locking portion, it can be easily opened. Moreover, since the enclosure wall like patent document 2 is unnecessary, a structure is also simple and, therefore, the processing cost of a metal mold | die does not increase.

次に、本願発明の実施形態を図面に基づいて説明する。   Next, an embodiment of the present invention will be described with reference to the drawings.

(1).第１実施形態（図１〜図４）
図１〜図４では第１実施形態を示している。図１はキャップを開いた状態での平面図、図２のうち（Ａ）は図１の縦断正面図、（Ｂ）は図１の IIB-IIB視断面図、図３はキャップを開いた状態での一部破断斜視図、図４はキャップを閉じた状態での縦断正面図である。 (1). First embodiment (FIGS. 1 to 4)
1 to 4 show the first embodiment. 1 is a plan view with a cap open, FIG. 2A is a longitudinal front view of FIG. 1, FIG. 1B is a cross-sectional view taken along IIB-IIB in FIG. 1, and FIG. FIG. 4 is a partially cutaway perspective view in FIG. 4, which is a longitudinal front view with the cap closed.

蓋装置は本体１とキャップ２とからなっており、両者は１本のセンターヒンジ３及び２本のサイドヒンジ４を介して一体に繋がっている。本体１は、容器の口部５に外側から嵌まる外筒６と、容器の口部５に内側から嵌まる内筒７と、内筒７の上端と一体に連続した注出口８と、注出口８の下端を封止する閉鎖板９とを備えている。容器の口部５の外面には環状係合溝５ａが形成されている一方、本体１の外筒６には、環状係合溝５ａと嵌合する環状突起６ａが形成されている。 The lid device includes a main body 1 and a cap 2, and both are integrally connected through one center hinge 3 and two side hinges 4. The main body 1 includes an outer cylinder 6 that fits into the mouth part 5 of the container from the outside, an inner cylinder 7 that fits into the mouth part 5 of the container from the inside, a spout 8 that is integrated with the upper end of the inner cylinder 7, And a closing plate 9 that seals the lower end of the outlet 8. While the outer surface of the mouth portion 5 of the container is formed with an annular engagement groove 5a, the outer cylinder 6 of the main body 1, an annular projection 6a to be fitted to the annular engaging groove 5a is formed.

外筒６と内筒７との上端は段部１０を介して一体に連続しており、段部１０には、注出口８を囲うリング部１１を形成している。注出口８はヒンジ３，４に近い半分程の部分が低くなるように段違いになっている。閉鎖板９にはループ状のスコアー（薄肉部）１２が形成されており、スコアー１２で囲われた部分の端部にプルリング（プルタブ）１３を一体に設けている。いうまでもないが、プリリング１３を引っ張ってスコアー１２の箇所を引き千切ることにより、内容物を注ぎ出すことができる。 The upper ends of the outer cylinder 6 and the inner cylinder 7 are integrally continuous through a step portion 10 , and a ring portion 11 that surrounds the spout 8 is formed in the step portion 10. The spout 8 is stepped so that a half portion near the hinges 3 and 4 is lowered. A loop-like score (thin wall portion) 12 is formed on the closing plate 9, and a pull ring (pull tab) 13 is integrally provided at the end of the portion surrounded by the score 12. Needless to say, the content can be poured out by pulling the pre-ring 13 and tearing off the portion of the score 12.

キャップ２は閉じた状態で本体２の段部１０に重なるように筒部と天板とを備えており、天板には注出口８に内側から嵌合する中足１４を設けている。また、キャップ２のうち軸心を挟んでヒンジ３，４と反対側に位置した自由端部には摘まみ片１５を突設している。摘まみ片１５の下面には指の引っ掛かりを良くするためのリブ１５ａを形成している。   The cap 2 is provided with a cylindrical portion and a top plate so as to overlap the stepped portion 10 of the main body 2 in a closed state, and the top plate is provided with a middle leg 14 that fits into the spout 8 from the inside. Further, a knob 15 is projected from a free end portion of the cap 2 that is located on the opposite side of the hinges 3 and 4 across the axis. A rib 15a is formed on the lower surface of the knob 15 for improving finger catching.

そして、本体１のうち軸心を挟んだヒンジ３，４と反対側の端部には、キャップ２の摘まみ片１５が嵌まり込む係止部１８を形成している。係止部１８は、本体１の外周面から外向きにはみ出る水平部１９と、水平部１９の外縁から立ち上がった壁部２０とを備えている。水平部１９は本体２の段部１０と同じ高さであり、この水平部１９には、キャップ２の摘まみ片１５と重なる窓穴２１が空いており、窓穴２１を挟んだ両側が、千切り可能なブリッジ部（弱化部）２２を介して本体１に繋がっている。壁部２０は、キャップ２の摘まみ片１５が嵌まるように門形に形成されている。すなわち、窓穴２１は壁部２０まで広がっている。 A locking portion 18 into which the knob piece 15 of the cap 2 is fitted is formed at the end of the main body 1 on the opposite side to the hinges 3 and 4 sandwiching the axis. The locking portion 18 includes a horizontal portion 19 that protrudes outward from the outer peripheral surface of the main body 1 and a wall portion 20 that rises from the outer edge of the horizontal portion 19. The horizontal portion 19 has the same height as the step portion 10 of the main body 2, and the horizontal portion 19 has a window hole 21 that overlaps with the knob piece 15 of the cap 2, and both sides sandwiching the window hole 21 are It is connected to the main body 1 via a bridge portion (weakening portion) 22 that can be shredded. The wall portion 20 is formed in a gate shape so that the knob 15 of the cap 2 is fitted. That is, the window hole 21 extends to the wall portion 20.

蓋装置１はキャップ２を開いた状態で成形（製造）される。そして、キャップ２を閉じると、図４に示すように、摘まみ片１５が係止部１８の弾性に抗して壁部２０の窓穴２１に嵌まり込み、すると、係止部１８を引き千切らない限りキャップ２を開けることはできない。このため、不正開封があればその事実を即座に視認できる。   The lid device 1 is molded (manufactured) with the cap 2 open. When the cap 2 is closed, as shown in FIG. 4, the knob 15 fits into the window hole 21 of the wall portion 20 against the elasticity of the locking portion 18, and then the locking portion 18 is pulled. The cap 2 cannot be opened unless it is broken. For this reason, if there is unauthorized opening, the fact can be immediately recognized.

そして、係止部１８の全体を除去するものであるため、係止部１８を除去した後は摘まみ片１５の全体が露出しており、このため、キャップ２を開けるに際しては摘まみ片１５に指をしっかりと掛けることができて、キャップ２の開き操作を容易に行うことができる。また、係止部１８は単純な形態であるため、構造が簡単で成形も容易である。   And since the whole latching | locking part 18 is removed, after removing the latching | locking part 18, the whole knob | pick piece 15 is exposed, Therefore, when opening the cap 2, the knob | pick piece 15 is exposed. A finger can be firmly placed on the cap 2 and the opening operation of the cap 2 can be easily performed. Moreover, since the latching | locking part 18 is a simple form, a structure is simple and shaping | molding is easy.

図３に一点鎖線で示すように、係止部１８の壁部２０を左右両側又は片側に張り出すことにより、切除するに際して摘まみ易くことも可能である。また、図４に一点鎖線で示すように、窓穴２１は係止部１８の壁部２０に開口した状態に形成せずに、壁部２０で摘まみ片１５の先端面を覆う形態となすことも可能である。更に、係止部１８の水平部１９には必ずしも窓穴２１を形成する必要はない。更に、図４に二点鎖線で示すように、水平部１９から下方に延びる縦リブ２３を形成することも可能である。 As shown by a chain line in FIG. 3, by protruding wall portion 20 of the locking portion 18 on the left and right sides or one side, it is also possible easily try knob when excised. Further, as shown by a one-dot chain line in FIG. 4, the window hole 21 is not formed in the state of opening in the wall portion 20 of the locking portion 18, and the wall portion 20 covers the tip end surface of the knob piece 15. It is also possible. Further, it is not always necessary to form the window hole 21 in the horizontal portion 19 of the locking portion 18. Furthermore, as indicated by a two-dot chain line in FIG. 4, it is possible to form vertical ribs 23 extending downward from the horizontal portion 19.

(2).容器からの取り外し対策
本実施形態では、本体１の段差部１０のうちヒンジ３，４に寄った略半分程度の範囲の箇所には、外筒６よりも外側に位置した上向きの長溝２４が形成されており、長溝２４を挟んで外側に位置したアウターリング２５にヒンジ３，４が一体成形されている。アウターリング２５を設けた部分では外筒６はその肉厚が他の部分に比べて薄くなっている。 (2) Measures for removing from the container In the present embodiment, the portion of the stepped portion 10 of the main body 1 that is approximately half of the stepped portion 10 close to the hinges 3, 4 has an upward facing position located outside the outer cylinder 6. A long groove 24 is formed, and hinges 3 and 4 are integrally formed on an outer ring 25 located on the outer side of the long groove 24. In the portion where the outer ring 25 is provided, the outer cylinder 6 is thinner than the other portions.

また、アウターリング２５はヒンジ３，４の箇所では下端の連結部２６を介して外筒６と一体に繋がっており、連結部２６の左右両側の部位では外筒６とは繋がっていない。そして、アウターリング２５のうち連結部２６の左右両端に位置した部位に縦長スコアー２７を形成している。   Further, the outer ring 25 is integrally connected to the outer cylinder 6 via the lower end connecting portion 26 at the hinges 3 and 4, and is not connected to the outer cylinder 6 at the left and right side portions of the connecting portion 26. And the longitudinally long score 27 is formed in the site | part located in the right-and-left both ends of the connection part 26 among the outer rings 25. FIG.

容器に包装された内容物を消費し切った後、キャップ２を手で掴んでいったん下向きに引っ張るとアウターリング１５は縦長スコアー２７の箇所で破断する。次に、キャップ２を上向きに引っ張ることにより、内外の筒６，７と容器の口部５との係合を解除して、本体１を容器の口部５から取外すことができる。このため、容器と蓋装置との分別を簡単に行える。   After the contents packed in the container are completely consumed, the outer ring 15 is broken at the position of the longitudinal score 27 when the cap 2 is grasped by hand and pulled downward once. Next, by pulling the cap 2 upward, the engagement between the inner and outer cylinders 6 and 7 and the mouth portion 5 of the container can be released, and the main body 1 can be detached from the mouth portion 5 of the container. For this reason, the container and the lid device can be easily separated.

(3).他の実施形態（図５）
図５では第２実施形態を示している。この第２実施形態は第１実施形態の変形例であり、係止部１８の壁部２０をブロック状に形成して、キャップ２の外周面と対向した面を、下端に行くに従ってキャップ２に近づくような傾斜面に形成している。このように形成すると、キャップ２の封止状態をより確実ならしめることができる。 (3). Other embodiment ( Fig. 5 )
FIG. 5 shows a second embodiment. Second Embodiment This is a modification of the first embodiment, the cap 2 according to form wall portion 20 of the locking portion 18 in a block shape, an outer peripheral surface opposite to the surface of the cap 2, go to the lower end It is formed in the inclined surface which approaches. If formed in this way, the sealed state of the cap 2 can be made more reliable.

図６では参考例を示している。（Ａ）は正面図、（Ｂ）は（Ａ）のＢ−Ｂ視断面図、（Ｃ）は（Ａ）のＣ−Ｃ視断面図である。この参考例では、係止部１８は、本体１の外周面に重なるような状態で配置されており、かつ、キャップ２の摘まみ片１５が嵌まる下向き開口の切り開き溝２８を有して門形（下向き開口コ字状）に形成されている。また、人が上端に指を掛け得るように、切り開き溝２８の上方に長く延びている。 FIG. 6 shows a reference example . (A) is a front view, (B) is a sectional view taken along line BB of (A), and (C) is a sectional view taken along line CC of (A). In this reference example , the locking portion 18 is arranged so as to overlap the outer peripheral surface of the main body 1, and has a downward opening slit 28 into which the knob 15 of the cap 2 is fitted. It is formed in a shape (downward opening U shape). Moreover, it extends long above the slit groove 28 so that a person can put a finger on the upper end.

更に、切り開き溝２８を挟んで両側に位置した部分は、その下端は屈曲可能なヒンジ部２９を介して本体１に繋がっており、また、上部は引き千切り可能なブリッジ部３０を介して本体１に繋がっている。そして、本体１の外周面のうち係止部１８の下方には、係止部１８を下方に引き起こした状態に保持する左右一対の保持片３１を形成している。保持片３１は平面視で鉤状に形成されている。   Further, the portions located on both sides of the slit groove 28 are connected to the main body 1 via a bendable hinge portion 29 at the lower end, and the upper portion is connected to the main body 1 via a bridge portion 30 that can be shredded. It is connected to. A pair of left and right holding pieces 31 is formed below the locking portion 18 on the outer peripheral surface of the main body 1 to hold the locking portion 18 in a state of being raised downward. The holding piece 31 is formed in a bowl shape in plan view.

この参考例では、係止部１８の上端に指を掛けて、ヒンジ部２９を支点にして係止部１８を下向きに回動させると、ブリッジ部３０が千切れてキャップ２を開けることができる。そして、係止部１８は保持片３１により、本体１に取り付いた状態のままに保持される。 In this reference example , when the finger is put on the upper end of the locking portion 18 and the locking portion 18 is turned downward with the hinge portion 29 as a fulcrum, the bridge portion 30 is broken and the cap 2 can be opened. . And the latching | locking part 18 is hold | maintained with the holding piece 31 in the state attached to the main body 1. FIG.

保持片３１を設けずに係止部１８を本体１から除去することも可能であるが、本参考例のように封止解除後も本体１に取り付いたままにしておくと、係止部１８もリサイクルできる利点がある。なお、キャップ２を閉じるときにブリッジ部３０が千切れないように、キャップ２を閉じるに際しては係止部１８のうちブリッジ部３０の箇所を外から押さえておくのが好ましい。 Although it is possible to remove the locking portion 18 from the main body 1 without providing the holding piece 31, if the locking portion 18 remains attached to the main body 1 even after the seal is released as in this reference example , Also has the advantage of being recyclable. In order to prevent the bridge portion 30 from being broken when the cap 2 is closed, it is preferable that the position of the bridge portion 30 in the locking portion 18 is pressed from the outside when the cap 2 is closed.
