Description

本発明は、中栓からオーバーキャップに移行する移行栓を備える抜栓キャップに関し、とくに、中栓にオーバーキャップをセットする際に、移行栓の脱落を防止可能な抜栓キャップに関するものである。 The present invention relates to a plug-out cap provided with a transition plug that shifts from the inner plug to the overcap, and more particularly to a plug-removal cap that can prevent the transition plug from falling off when the overcap is set on the inner plug.

従来、ドレッシングや調味料などを収容する食品容器には、開封時まで容器内を密封状態にしておくために、容器口部に装着された中栓に、弱化部により画成された除去壁部を形成した隔壁を設け、除去壁部に設けられたプルリングを引き上げて除去壁部を引きちぎって注出口を開栓する抜栓キャップが広く用いられている。 Conventionally, for food containers that store dressings and seasonings, in order to keep the inside of the container in a sealed state until opening, the inner plug attached to the container mouth is covered with a removal wall defined by a weakened part. A plug-out cap is widely used in which a partition wall is provided and a pull ring provided on the removal wall portion is pulled up to tear off the removal wall portion to open a spout.

しかしながら、プルリングを引き上げて弱化部を破断するには比較的大きな力が必要であり、指先の力が弱い子供やお年寄りには開封が困難なことがあるため、プルリングによる開栓ではなく、オーバーキャップの螺合部の回転動作によって開栓することができる抜栓キャップが従来から知られている(例えば、特許文献1参照)。 However, it requires a relatively large force to pull up the pull ring and break the weakened part, and it may be difficult for children and the elderly with weak fingertips to open it. A cap that can be opened by rotating the screwed portion of the cap has been conventionally known (see, for example, Patent Document 1).

特開2015-163525号公報JP-A-2015-163525

上記特許文献1記載の抜栓キャップは、中栓の注出筒内周面に薄肉弱化部を介して連結された栓体と、キャップの切断筒部との間に、キャップを螺脱させるときのみ係合するラチェット機構を構成する第1歯部と第2歯部が配設されているから、プルリングを用いずに開栓することができるとともに、難しい操作をすることなく、通常の開蓋操作と同様にキャップをねじの解放方向に回動するだけで簡単に開栓することができる。
しかしながら、上記特許文献1記載の抜栓キャップは、内容物を充填した容器本体の口部に中栓を装着した後、中栓にオーバーキャップをセットして締め込む際に、栓体の薄肉弱化部が破断したり、薄肉弱化部が破断して移行栓が容器本体内に落下するおそれがあり、移行栓が容器本体内に落下した場合に確認することが困難であった。
The unplugging cap described in Patent Document 1 is only used when the cap is screwed off between the plug body connected to the inner peripheral surface of the dispensing cylinder of the inner plug via the thinning weakening portion and the cutting cylinder portion of the cap. Since the first and second teeth constituting the engaging ratchet mechanism are arranged, the cap can be opened without using a pull ring, and the normal lid opening operation can be performed without any difficult operation. Similarly, the cap can be easily opened by simply rotating the cap in the release direction of the screw.
However, the unplugging cap described in Patent Document 1 is a thinned portion of the plug body when the inner plug is attached to the mouth of the container body filled with the contents and then the overcap is set on the inner plug and tightened. There is a risk that the transition plug may break or the thin-walled weakened portion may break and the transition plug may fall into the container body, and it is difficult to confirm when the transition plug falls into the container body.

音出し部材46は、頂壁40の下面から垂設された剛直な棒状の基部57と、基部57の下端面から垂設され、周方向の厚さが弾性変形可能な薄肉に形成される振動片58とからなっている。
音出し部材46は、オーバーキャップCの締め込み終了直前に振動片58の先端が中栓Bの音出し突部23に当接し、振動片58を湾曲変形させながら締め込みが進み、締め込み終了と同時に振動片58が音出し突部23を乗り越え、復元しようとすることにより、振動し、音が発生されるように設定される。
本実施例では、基部57は、同心円状の120°間隔で3個所に分かれて配設されているが、基部57は、リング状に連続したものであっても構わない。
The sound producing member 46 is hung from a rigid rod-shaped base 57 suspended from the lower surface of the top wall 40 and from the lower end surface of the base 57, and is formed into a thin wall having an elastically deformable thickness in the circumferential direction. It consists of 58 pieces.
Immediately before the end of tightening of the overcap C, the tip of the vibrating piece 58 of the sound emitting member 46 comes into contact with the sound emitting protrusion 23 of the inner plug B, and the tightening proceeds while the vibrating piece 58 is curved and deformed, and the tightening is completed. At the same time, the vibrating piece 58 is set to vibrate and generate sound by overcoming the sound output protrusion 23 and trying to restore it.
In the present embodiment, the base portion 57 is arranged in three places at 120 ° intervals concentrically, but the base portion 57 may be continuous in a ring shape.

中足部44は筒状であり、閉蓋されたときに注出筒11の外側に来るように設けられている。また、中足部44の長さは、中栓Bのねじ周壁8の高さより大きくすることが好ましい。
オーバーキャップCを中栓Bに螺合させる際に、中足部44によって注出筒11が案内されて、位置合わせが容易となるとともに、位置合わせがうまくいかない限り、ねじ筒部45の雌ねじ55がねじ周壁8の雄ねじ20に到達しないため、螺合することができず、無理な螺合を防止することができる。
The midfoot portion 44 has a tubular shape and is provided so as to come to the outside of the dispensing cylinder 11 when the lid is closed. Further, the length of the midfoot portion 44 is preferably larger than the height of the screw peripheral wall 8 of the inner plug B.
When the overcap C is screwed into the inner plug B, the dispensing cylinder 11 is guided by the midfoot portion 44 to facilitate the alignment, and unless the alignment is successful, the female screw 55 of the screw cylinder portion 45 is used. Since it does not reach the male screw 20 of the screw peripheral wall 8, it cannot be screwed, and it is possible to prevent unreasonable screwing.

次に、本実施例の使用態様と作用効果について説明する。
まず、本実施例の抜栓キャップを容器本体Aに装着するには、内容物を充填した容器本体Aの口部1に中栓Bを打栓した後、中栓BにオーバーキャップCをセットして締め込む工程を経る必要があるが、オーバーキャップCを中栓Bにセットする際に、移行栓13の薄肉弱化部12が破断したり、薄肉弱化部12が破断して移行栓13が容器本体A内に落下するおそれがある。
そこで、薄肉弱化部12が破断したり、移行栓13が容器本体A内に落下するのを防止するために、中栓Bの下方には、図3に示すように、2個の係合片18が内側に向けて斜め下方に延びて成型されている。
Next, the usage mode and the action and effect of this example will be described.
First, in order to attach the unplugging cap of this embodiment to the container body A, the inner plug B is tapped into the mouth 1 of the container body A filled with the contents, and then the overcap C is set in the inner plug B. However, when the overcap C is set in the inner plug B, the thin-walled weakened portion 12 of the transition plug 13 is broken, or the thin-walled weakened portion 12 is broken and the transition plug 13 is a container. There is a risk of falling into the main body A.
Therefore, in order to prevent the thinning weakening portion 12 from breaking or the transition plug 13 from falling into the container body A, two engaging pieces are placed below the inner plug B as shown in FIG. 18 is molded so as to extend diagonally downward toward the inside.

このため、中栓Bを容器本体Aの口部1に打栓する前に、図6に示すように、各係合片18を移行栓13側に向けて折り曲げる必要があり、係合片18の折り曲げは、例えば、加熱手段を有する治具等を用いて、係合片18を折り曲げた状態に保つようにすればよい。
なお、係合片18は、同肉厚であるが、基端部18aを薄肉等にしてもよい。
次に、中栓Bを内容物を充填した容器本体Aに打栓するには、口部1に中栓Bの嵌合筒部4を当てがい、上壁7を上から押さえると、口部1が嵌合筒部4に嵌合して外筒5を外側にわずかに押し広げ、係止縮径部26が口部1の係止突条2に係合可能になる。
Therefore, before the inner plug B is plugged into the mouth portion 1 of the container body A, it is necessary to bend each engaging piece 18 toward the transition plug 13 side as shown in FIG. 6, and the engaging piece 18 needs to be bent. For bending, for example, a jig or the like having a heating means may be used to keep the engaging piece 18 in a bent state.
Although the engaging piece 18 has the same wall thickness, the base end portion 18a may have a thin wall or the like.
Next, in order to plug the inner plug B into the container body A filled with the contents, the fitting cylinder portion 4 of the inner plug B is applied to the mouth portion 1, and the upper wall 7 is pressed from above to form the mouth portion. 1 fits into the fitting cylinder portion 4, and the outer cylinder 5 is slightly expanded outward, so that the locking reduced diameter portion 26 can engage with the locking ridge 2 of the mouth portion 1.

次に、オーバーキャップCを中栓Bに螺合するには、音出し部材46の内側に比較的長い中足部44が設けてあるため、音出し部材46の振動片58が、注出筒11に入り込むのをブロックするとともに、中足部44によって注出筒11が案内され、オーバーキャップCの位置合わせが容易になり、中栓Bの移行栓13と、オーバーキャップCの係着部42および密封筒43との係合が確実に行われる必要がある。
位置合わせが決まって、オーバーキャップCのねじ筒部45の雌ねじ55を中栓Bのねじ周壁8の雄ねじ20に螺合して締め込む際には、オーバーキャップCが回転し、オーバーキャップCの密封筒43の係合腕51は中栓Bの移行栓13の係合突起16の非係合面16bに乗り上げ、係合突起16を乗り越えて、オーバーキャップCの回転を許容する。
この際に、移行栓13は、薄肉弱化部12の周辺を係合片18(受け部)で支えられているために、移行栓13に下方向の力が作用しても薄肉弱化部12が不用意に破断することを防止できる。
Next, in order to screw the overcap C into the inner plug B, since the relatively long midfoot portion 44 is provided inside the sound output member 46, the vibrating piece 58 of the sound output member 46 is a pouring cylinder. In addition to blocking entry into 11, the midfoot portion 44 guides the dispenser cylinder 11, facilitating the alignment of the overcap C, and the transition plug 13 of the inner plug B and the engagement portion 42 of the overcap C. And it is necessary that the engagement with the sealing cylinder 43 is surely performed.
When the alignment is determined and the female screw 55 of the screw cylinder portion 45 of the overcap C is screwed into the male screw 20 of the screw peripheral wall 8 of the inner plug B and tightened, the overcap C rotates and the overcap C The engaging arm 51 of the sealing cylinder 43 rides on the non-engaging surface 16b of the engaging protrusion 16 of the transition plug 13 of the inner plug B, gets over the engaging protrusion 16, and allows the overcap C to rotate.
At this time, since the transition plug 13 is supported by the engaging piece 18 (receiving portion) around the thin-walled weakening portion 12, even if a downward force acts on the transition plug 13, the thin-walled weakening portion 12 is supported. It is possible to prevent accidental breakage.

さらにオーバーキャップCが下降することにより、オーバーキャップCの係着部42の第2係合突部50が中栓Bの移行栓13の第1係合突部17を乗り越えて、筒状壁14の内周面に嵌合するようになる。
同時に、ねじ筒部45の下部のくさび状凹部56が中栓Bの上壁7のストッパー24に嵌合するようになり、さらに、雄ねじ20と雌ねじ55の締結が進んでいくと、くさび状凹部56の第2当接面56aがストッパー24の第1当接面24aに当接して両ねじの締結が完了する。
Further, as the overcap C is lowered, the second engaging protrusion 50 of the engaging portion 42 of the overcap C gets over the first engaging protrusion 17 of the transition plug 13 of the inner plug B, and the tubular wall 14 It comes to fit on the inner peripheral surface of.
At the same time, the wedge-shaped recess 56 at the bottom of the screw cylinder portion 45 comes to fit into the stopper 24 of the upper wall 7 of the inner plug B, and further, as the male screw 20 and the female screw 55 are fastened, the wedge-shaped recess 56 is further advanced. The second contact surface 56a of 56 abuts on the first contact surface 24a of the stopper 24, and the fastening of both screws is completed.

両ねじの締結が完了する前には、図7(a)、図8(a)に示すように、オーバーキャップCの回転および下降により、オーバーキャップCのそれぞれの音出し部材46の振動片58先端が、中栓Bの天壁9のそれぞれの音出し突部23に当接し、さらに回転が進むと、図8(b)に示すように、振動片58が湾曲変形しながら進み、最後は、図1(b)、図7(b)に示すように、振動片58の先端が音出し突部23を乗り越える。
振動片58の先端が音出し突部23を乗り越えると、湾曲変形した振動片58が復元しようとし、振動し、音が発せられる。
この音により、本発明の利用者は、感覚的にキャップの閉蓋終了を知ることができる。
Before the fastening of both screws is completed, as shown in FIGS. 7 (a) and 8 (a), the vibration pieces 58 of the respective sound producing members 46 of the overcap C are caused by the rotation and lowering of the overcap C. When the tip abuts on each sound output protrusion 23 of the top wall 9 of the inner plug B and the rotation progresses further, as shown in FIG. 8B, the vibrating piece 58 advances while being curved and deformed, and finally. , As shown in FIGS. 1 (b) and 7 (b), the tip of the vibrating piece 58 gets over the sound output protrusion 23.
When the tip of the vibrating piece 58 gets over the sound emitting protrusion 23, the curved and deformed vibrating piece 58 tries to be restored, vibrates, and a sound is emitted.
From this sound, the user of the present invention can intuitively know the end of closing the cap.

次に、本実施例の抜栓キャップが装着された容器を使用するには、オーバーキャップCを中栓Bに対して螺脱方向に回転させる。
回転が進むと、図8(c)に示すように、オーバーキャップCの音出し部材46の振動片58先端が、中栓Bの天壁9の音出し突部23に当接し、さらに回転が進むと、振動片58が湾曲変形しながら進み、振動片58の先端が音出し突部23を乗り越え、湾曲変形した振動片58が復元して振動し、音が発せられる。
Next, in order to use the container to which the unplugging cap of this embodiment is attached, the overcap C is rotated with respect to the inner plug B in the screwing direction.
As the rotation progresses, as shown in FIG. 8C, the tip of the vibrating piece 58 of the sound emitting member 46 of the overcap C comes into contact with the sound emitting protrusion 23 of the top wall 9 of the inner plug B, and further rotation occurs. As the vibration piece 58 advances, the vibration piece 58 advances while being curved and deformed, the tip of the vibration piece 58 gets over the sound output protrusion 23, and the curved and deformed vibration piece 58 is restored and vibrates, and a sound is emitted.

さらに回転すると、オーバーキャップCの密封筒43の内周面から延びる係合腕51が回動して、その先端係合部53の第2係合面52が中栓Bの移行栓13の係合突起16の第1係合面16aに当接するようになり、オーバーキャップCの回転力がラチェット機構を介して移行栓13に加わるようになる。
係合腕51の先端係合部53は、腕部54より厚肉に形成されているので、第2係合面52は第1係合面16aに広い面積でしっかり当接係合するとともに回転力に負けない強度を有する。
Further rotation, the engaging arm 51 extending from the inner peripheral surface of the sealing cylinder 43 of the overcap C rotates, and the second engaging surface 52 of the tip engaging portion 53 engages with the transition plug 13 of the inner plug B. It comes into contact with the first engaging surface 16a of the joint projection 16, and the rotational force of the overcap C is applied to the transition plug 13 via the ratchet mechanism.
Since the tip engaging portion 53 of the engaging arm 51 is formed to be thicker than the arm portion 54, the second engaging surface 52 firmly abuts and engages with the first engaging surface 16a over a wide area and rotates. Has strength that is not defeated by force.

このとき、係着部42の第2係合突部50が筒状壁14の内周面に緊密に嵌合しているので、筒状壁14を内側から補強してオーバーキャップCの回転力がラチェット機構を介して移行栓13に伝わりやすくなっているとともに、ねじの回転に伴って移行栓13を上方に引き上げる力を発生させる。
オーバーキャップCの回転が進むと、移行栓13に加わる回転力と引き上げ力により、ついには薄肉弱化部12が破断して注出筒11内に注出口が開栓され、注出筒部10から分離された移行栓13は、筒状壁14に係合する係着部42によって引き上げられてオーバーキャップCとともに上昇していく。
At this time, since the second engaging protrusion 50 of the engaging portion 42 is tightly fitted to the inner peripheral surface of the tubular wall 14, the tubular wall 14 is reinforced from the inside and the rotational force of the overcap C is applied. Is easily transmitted to the transition plug 13 via the ratchet mechanism, and a force is generated to pull the transition plug 13 upward as the screw rotates.
As the rotation of the overcap C progresses, the thinning weakening portion 12 finally breaks due to the rotational force and the pulling force applied to the transition plug 13, and the spout is opened in the pouring cylinder 11 from the pouring cylinder portion 10. The separated transition plug 13 is pulled up by the engagement portion 42 engaged with the tubular wall 14 and rises together with the overcap C.

さらに、雌ねじ55が雄ねじ20から螺脱して、図9に示すように、オーバーキャップCを中栓Bから離脱させれば、オーバーキャップCとともに移行栓13が除去された注出筒部10の開口から容器内の内容物を注出することができる。 Further, when the female screw 55 is screwed out from the male screw 20 and the overcap C is separated from the inner plug B as shown in FIG. 9, the opening of the dispensing cylinder portion 10 from which the transition plug 13 is removed together with the overcap C. The contents in the container can be poured out from.

内容物を注出した後、再度オーバーキャップCを中栓Bに螺合する際には、中足部44によって中栓Bに対するオーバーキャップCの位置合わせが容易であり、螺合が終了した場合には、オーバーキャップCの密封筒43の外周が注出筒11内周に密着して容器内を密封することができる。 When the overcap C is screwed into the inner plug B again after the contents are poured out, it is easy to align the overcap C with respect to the inner plug B by the midfoot portion 44, and the screwing is completed. The outer circumference of the sealing cylinder 43 of the overcap C is in close contact with the inner circumference of the dispensing cylinder 11 to seal the inside of the container.

また、両ねじの締結が完了する際には、再度、音出し部材46の振動片58先端が、音出し突部23に当接して振動し、音が発せられるので、本発明の利用者は、感覚的にオーバーキャップCの閉蓋終了を知ることができる。
本発明の利用者は、オーバーキャップCの閉蓋終了を感覚的に知ることができるので、オーバーキャップCを中栓Bに対して、無理に回転しすぎて、螺合が強くなりすぎ、開蓋に苦労することを防止できる。
Further, when the fastening of both screws is completed, the tip of the vibrating piece 58 of the sound producing member 46 abuts on the sound producing protrusion 23 and vibrates again, so that the user of the present invention emits a sound. , It is possible to intuitively know the end of closing the overcap C.
Since the user of the present invention can intuitively know the end of closing the overcap C, the overcap C is forcibly rotated with respect to the inner plug B, the screwing becomes too strong, and the overcap C is opened. It is possible to prevent the lid from being troubled.

本実施例では、開蓋時や閉蓋時に、音を発するように、オーバーキャップCの音出し部材46と、中栓Bの天壁9の音出し突部23とを設けているが、これらは、省いても構わない。
さらに、オーバーキャップCの中足部44も省くことができる。
In this embodiment, the sound output member 46 of the overcap C and the sound output protrusion 23 of the top wall 9 of the inner plug B are provided so as to generate a sound when the lid is opened or closed. May be omitted.
Further, the midfoot portion 44 of the overcap C can also be omitted.

本実施例の抜栓キャップは、使用済みの容器を廃棄する際に、簡単な操作で容器本体Aから中栓Bを分離することにより、分別して廃棄することができる。
まず、図2および図4に示す縦切断部30付近の引っ掛け部31に手指を掛けて把持部29を手前に引っ張ると、縦切断部30が破断し、把持部29が外方に展開する。
把持凹凸部32を指で把持しながら、さらに把持部29を引っ張ると、貫通スリット28の終端部28bから周方向切断部34の端部34aへと破断が進んでいく。
When disposing of the used container, the unplugging cap of this embodiment can be separated and disposed of by separating the inner plug B from the container main body A by a simple operation.
First, when the grip portion 29 is pulled toward the hook portion 31 near the vertical cut portion 30 shown in FIGS. 2 and 4, the vertical cut portion 30 is broken and the grip portion 29 expands outward.
When the gripping portion 29 is further pulled while gripping the gripping uneven portion 32 with a finger, the break progresses from the terminal portion 28b of the through slit 28 to the end portion 34a of the circumferential cutting portion 34.

周方向切断部34が端部34bまで破断したところで、周方向切断部34の破断は、停止する。そこで、把持部29を引き上げると、周方向切断部34が破断された範囲内では、係止縮径部26の係止突条2への係合が解除され、係止縮径部26による口部1への拘束が解除されるので、把持部29の引き上げに伴って、破断しないで残った厚肉連結部35を介して中栓Bを容器本体Aから離脱させ分別廃棄することができる。 When the circumferential cutting portion 34 breaks to the end portion 34b, the breaking of the circumferential cutting portion 34 stops. Therefore, when the grip portion 29 is pulled up, the engagement of the locking reduced diameter portion 26 with the locking ridge 2 is released within the range where the circumferential cutting portion 34 is broken, and the mouth of the locking reduced diameter portion 26 is released. Since the restraint on the portion 1 is released, the inner plug B can be separated from the container body A via the thick-walled connecting portion 35 remaining without breaking as the grip portion 29 is pulled up, and can be separated and discarded.

本実施例では、オーバーキャップCが螺合するための回転角度を少なくするために雄ねじ20および雌ねじ55を3条ねじとしているが、別に回転の範囲を気にしないものであれば、3条ねじではなく、単数および複数の条数のねじとしてもよい。 In this embodiment, the male screw 20 and the female screw 55 are set as three-threaded screws in order to reduce the rotation angle for the overcap C to be screwed. However, if the range of rotation is not a concern, the three-threaded screw Instead, it may be a single screw or a screw having a plurality of threads.

本発明の抜栓キャップは、注出筒部の薄肉弱化部の下方に受け部を設けることによって、中栓にオーバーキャップをセットする際に、薄肉弱化部が破断したり、移行栓が容器本体内に落下するのを防止することができるので、子供やお年寄りでも安心して利用できる容器として好適である。 In the unplugging cap of the present invention, by providing a receiving portion below the thin-walled weakened portion of the dispensing cylinder portion, when the overcap is set on the inner plug, the thin-walled weakened portion is broken or the transition plug is inside the container body. Since it can be prevented from falling into the container, it is suitable as a container that can be safely used by children and the elderly.
