Description
本発明は容器に関する。 The present invention relates to a container.
容器に高密閉性を付与するために口部開口を閉塞する為にアルミシール等のシール材を貼着することが行われているが、これらはその為の設備を必要とし、また、余分な貼着工程を必要とするため改善が望まれている。これに伴って、シール材の貼着を必要とせずに高密閉性を現出する容器蓋が提案されている（例えば、特許文献１参照）。 In order to close the opening of the mouth in order to give the container a high sealing property, a sealing material such as an aluminum seal is applied. Improvement is desired because it requires a sticking process. In connection with this, the container lid which reveals high airtightness without requiring sticking of a sealing material is proposed (for example, refer to patent documents 1).
上記容器蓋は、蓋体本体と該本体へ被蓋する外蓋とからなり、蓋体本体は平板状の天板部と、蓋体本体を容器口部へ強固に嵌合固定する円筒状の側壁部とを有し、蓋体本体の天板部には内部に空隙を有する筒状体を形成し、該筒状体の胴部に薄肉部を設けて該筒状体を中間位置にて折損することにより筒状体上方部分を折損除去可能とし、又、外蓋の天板部裏面には係止突起を設け、以て折損除去した筒状体上方部分を係止突起により筒状体上蓋を下方とする様に外蓋天板部裏面に取り付け得る構造としている。
上記容器蓋を用いた容器では、開封に当たり筒状体を手等で折損した後逆さまにして外蓋天板部裏面に取り付けるという操作上の面倒があり、その際収納物が飛散する等の虞れもある。本発明はスパウトの筒口を閉塞する閉塞板を一体に形成し、特殊構成のラチェット機構を採用してキャップの螺脱の際に閉塞板を切り放して開口することができ、しかもキャップの螺着時にはラチェットの各歯が容易に乗り越えることができるとともに、キャップ螺脱時には少なくともラチェットの一方の歯群が硬化して各歯の歯合を外れ難いものとしてより確実な開封を行える容器を提案する。 In the container using the container lid described above, there is an operational trouble that the cylindrical body is broken by hand when opening the container, and then turned upside down and attached to the back surface of the outer lid top plate part. There is also. The present invention integrally forms a closing plate for closing the tube port of the spout, adopts a ratchet mechanism with a special configuration, can be opened by cutting the closing plate when the cap is screwed, and when the cap is screwed A container is proposed in which each tooth of the ratchet can easily get over, and at least one tooth group of the ratchet is hardened when the cap is unscrewed so that it is difficult to disengage each tooth.
第１の手段として、容器体Ａと、該容器体の口部２に筒状の本体部B1にキャップB3を螺着したスパウトＢとを設け、前記スパウトは、周縁部を薄肉破断部８を介して連結した閉塞板９により前記本体部の筒口７を閉塞するとともに、前記閉塞板と前記キャップとの間にラチェット機構を設け、該ラチェット機構は、前記閉塞板上の第１歯群ａと、前記キャップ内に嵌着固定するとともに、前記キャップの螺着時に前記第１歯群ａと非係合で螺脱時に係合する第２歯群ｂとから構成し、前記キャップ螺着後の加熱処理により前記第１歯群ａ，前記第２歯群ｂのうち、少なくとも一方の歯群が加熱による結晶化によって硬化する如く構成した。 As a first means, a container body A and a spout B in which a cap B 3 is screwed to a cylindrical main body B 1 are provided at the mouth portion 2 of the container body. The cylinder port 7 of the main body is closed by a closing plate 9 connected via 8 and a ratchet mechanism is provided between the closing plate and the cap, and the ratchet mechanism includes a first tooth group on the closing plate. a, and a second tooth group b that is engaged and fixed in the cap and is engaged with the first tooth group a when the cap is screwed and disengaged. By the subsequent heat treatment, at least one tooth group out of the first tooth group a and the second tooth group b was hardened by crystallization by heating.
第２の手段として、前記第１の手段に於いて、前記第２歯群ｂを構成する歯部材B4を結晶性樹脂により形成し、該結晶性樹脂の結晶化開始温度以上の温度で前記加熱処理を行うことにより前記第２歯群ｂが硬化する如く構成した。 As a second means, in the first means, the tooth member B 4 constituting the second tooth group b is formed of a crystalline resin, and the temperature is equal to or higher than the crystallization start temperature of the crystalline resin. The second tooth group b was configured to be cured by heat treatment.
第３の手段として、前記第２の手段に於いて、前記結晶性樹脂としてポリエチレンテレフタレートを採用する。 As a third means, polyethylene terephthalate is adopted as the crystalline resin in the second means.
第４の手段として、前記第１の手段又は第２の手段又は第３の手段に於いて、前記加熱処理として加熱殺菌処理を採用する。 As a fourth means, a heat sterilization treatment is adopted as the heat treatment in the first means, the second means or the third means.
本発明の容器は、螺着後の加熱処理によりラチェット機構を構成する第１歯群ａ，第２歯群ｂのうち、少なくとも一方が加熱による結晶化によって硬化する如く構成したので、第２歯群ｂを硬化する如く構成した場合、キャップB3の螺着時には硬化前の柔らかい状態の第２歯群ｂがもともと螺着時非係合形態の第１歯群ａを容易に乗り越えてキャップB3を装着することができ、また、螺脱に際しては第２歯群ｂが硬化しているため第２歯群ｂが第１歯群ａを乗り越えて空回りする等の不都合を生じる虞れを確実に防止し、その結果、薄肉破断部８の破断を確実に行える。また、従前通り収納物の殺菌処理等を筒口からの収納物の漏れ等を心配することなく円滑に行えるものであり、キャップB3を螺脱するという操作のなかで閉塞板９を破断して筒口７を開口するという開封を行えるものであり、取り扱い操作が極めて便利となる。 Since the container of the present invention is configured such that at least one of the first tooth group a and the second tooth group b constituting the ratchet mechanism by heat treatment after screwing is cured by crystallization by heating, the second tooth When the group b is configured to be hardened, when the cap B 3 is screwed, the second tooth group b in a soft state before being hardened easily gets over the first tooth group a which is not engaged at the time of screwing. 3 and the second tooth group b is hardened during screwing, so that there is a possibility that the second tooth group b will run over the first tooth group a and cause inconvenience. As a result, the thin broken portion 8 can be reliably broken. It is intended performed smoothly without concern for leakage or the like of the housing of the snout sterilized etc. as before storage was ruptured the closing plate 9 among the operation of the cap B 3 to unscrewed The tube opening 7 can be opened, and the handling operation is extremely convenient.
第２歯群ｂを構成する部材を結晶性樹脂により形成し、該結晶性樹脂の結晶化開始温度以上の温度で前記加熱処理を行うことにより前記第２歯群ｂが硬化する如く構成した場合には、樹脂の弾力性により螺着時の第１，第２の各歯群の相互乗り越えが極めて容易であり、しかも、螺着後の加熱処理により第２歯群が硬化されるので各第１，第２歯群のより確実な歯合を得られる。第２歯群の硬化は、螺着後の加熱処理により樹脂の結晶化度が上昇することにより硬化される。結晶性樹脂のうちでもポリエチレンテレフタレートが上記要求を充分満足できるため好ましく使用される。 When the member constituting the second tooth group b is formed of a crystalline resin and the heat treatment is performed at a temperature equal to or higher than the crystallization start temperature of the crystalline resin so that the second tooth group b is cured. In addition, the elasticity of the resin makes it extremely easy for the first and second tooth groups to cross over each other at the time of screwing, and the second tooth group is hardened by the heat treatment after screwing, so A more reliable engagement of the first and second tooth groups can be obtained. The second tooth group is cured by increasing the crystallinity of the resin by heat treatment after screwing. Among the crystalline resins, polyethylene terephthalate is preferably used because it can sufficiently satisfy the above requirements.
また、加熱処理として加熱殺菌処理を採用することにより加熱殺菌と第２歯群ｂの硬化とを同時に行えて作業効率を向上できる。 Further, by adopting a heat sterilization treatment as the heat treatment, the heat sterilization and the hardening of the second tooth group b can be performed at the same time, and the working efficiency can be improved.
以下、本発明の実施例の形態を図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図１から図５は本発明容器の一例を示し、該容器１は、容器体Ａと、スパウトＢとを備えている。 1 to 5 show an example of the container of the present invention, and the container 1 includes a container body A and a spout B.
スパウトＢは、本体部B1と、パイプB2と、キャップB3と、ラチェット形成用の歯部材B4とを備えている。本体部B1は前記容器体Ａの口部２に外周を溶着固定する筒状をなし、合成樹脂等によりパイプB2と一体に形成される。また、本体部B1の外周下部には口部２の密な溶着を可能ならしめるために、凹凸面とした帯状の融着外面ｆを設けており、融着外面ｆ上方には一対のフランジ３，４を突設し、その更に上方外周に突条５及び螺条６を順次周設している。尚、上記融着外面ｆはこの形状に限定されず、例えば、平面視紡錘形状をなす帯状融着面であっても、平面視楕円状をなす帯状融着面であっても、左右一対の板状突起の両側面であっても良い。また、本体部B1の上端の筒口７を、周縁部を薄肉破断部８を介して連結した閉塞板９により閉塞している。この閉塞板９は中央部を隆起した形態をなし、本体部B1内の筒口７の上端から一定距離離れた下方位置に薄肉破断部８を介して周縁部を連結している。 Spout B includes a main body B 1, a pipe B 2, is provided with a cap B 3, and a tooth member B 4 for the ratchet formation. The main body B 1 has a cylindrical shape in which the outer periphery is welded and fixed to the mouth 2 of the container body A, and is formed integrally with the pipe B 2 by synthetic resin or the like. In addition, a belt-like fusion outer surface f which is an uneven surface is provided at the lower outer periphery of the main body B 1 so that the mouth portion 2 can be closely welded, and a pair of flanges is provided above the fusion outer surface f. Projections 3 and 4 are provided, and a protrusion 5 and a screw 6 are sequentially provided on the upper outer periphery. The fusion outer surface f is not limited to this shape. For example, the fusion outer surface f may be a belt-like fusion surface having a spindle shape in plan view or a belt-like fusion surface having an elliptical shape in plan view. It may be both side surfaces of the plate-like protrusion. Further, the cylindrical port 7 at the upper end of the main body B 1 is closed by a closing plate 9 having a peripheral edge connected through a thin broken portion 8. The closing plate 9 has a form in which the central portion is raised, and a peripheral portion is connected to a lower position separated from the upper end of the tube port 7 in the main body B 1 by a certain distance through a thin broken portion 8.
パイプB2は、前記本体部B1と内部を連通して容器体Ａ内に垂設したもので、容器体Ａ内の収納物を円滑に且つ効率良く吸引するために作用し、また、可撓性を備えた容器体Ａの保形にも寄与する。図示例では、本体部B1の下端開口と連通して上端を一体に連結し、容器体Ａ内下部に下端を垂下させた管状をなしている。また、パイプB2には窓孔10を穿設している。この窓孔10の数，位置，大きさ等は適宜選択できる。 The pipe B 2 communicates with the main body B 1 and is suspended in the container body A. The pipe B 2 acts to suck the contents in the container body A smoothly and efficiently. This also contributes to the shape retention of the container A having flexibility. In the illustrated example, integrally connected to the upper end in communication with the lower end opening of the main body B 1, it has a tubular shape that has suspended the lower end to the lower container body A. Also bored a window opening 10 in the pipe B 2. The number, position, size, etc. of the window holes 10 can be selected as appropriate.
キャップB3も合成樹脂により形成され、本体部B1外周に螺着している。図示例では、周壁20上端縁より頂壁21を延設した下端開口の有頂筒状をなし、周壁20内周に周設した螺条22を前記本体部B1の螺条６に螺合する如く構成している。また、本体部B1とキャップ周壁20との間に、キャップの螺着時に密接するシール機能を付与している。このシール機能は密接した部分の上下を気密，液密に区画する。具体的には本体部B1の外周上端部に対応するキャップ周壁20内周面を密に嵌合させている。 Also the cap B 3 is formed of synthetic resin, it is screwed to the main body B 1 circumference. In the example shown in the figure, the top wall 21 is extended from the upper end edge of the peripheral wall 20 and has a top-bottomed cylindrical shape. A screw 22 provided around the inner periphery of the peripheral wall 20 is screwed to the screw 6 of the main body B 1. It is configured as shown. In addition, a sealing function is provided between the main body B 1 and the cap peripheral wall 20 so as to be in close contact when the cap is screwed. This sealing function partitions the top and bottom of the close part in an airtight and liquid tight manner. Specifically it is tightly fitted the cap wall 20 inner peripheral surface corresponding to the outer peripheral upper end portion of the main body portion B 1.
本発明では、閉塞板９とキャップB3内との間に、キャップB3の螺脱方向の回動を防止するラチェット機構を設けている。従って、キャップB3を螺着する際は容易にその操作を行えるのに対し、螺脱時には閉塞板９がキャップB3と一体に螺脱方向に回動しようとし、その結果、薄肉破断部８が破断して前記筒口７が開口する如く構成している。 In the present invention, a ratchet mechanism for preventing the cap B 3 from rotating in the screwing direction is provided between the closing plate 9 and the cap B 3 . Accordingly, when the cap B 3 is screwed, the operation can be easily performed, but at the time of screwing, the closing plate 9 tries to rotate integrally with the cap B 3 in the screwing direction. Is configured such that the tube opening 7 is opened.
ラチェット機構は、上記閉塞板９上の第１歯群ａと、前記キャップB3内に嵌着固定するとともに、前記キャップの螺着時に前記第１歯群ａと非係合で螺脱時に係合する第２歯群ｂとから構成している。図示例では、上記閉塞板９上に突設した円柱状凸部11の外周に周設した第１歯群ａと、キャップB3の周壁20上部内周に嵌着固定した固定筒30内面より内方へ突設した第２歯群ｂとで構成しており、従って、第１歯群ａは本体部B1と一体に形成され、第２歯群ｂは固定筒30と一体のラチェット形成用の歯部材B4として本体部B1及びキャップB3とは別体に形成されている。また、第１歯群ａは所定方向に傾いた三角板状の単位歯12を所定数前記円柱状凸部11外周に連設して構成しており、第２歯群ｂは、所定方向に傾いた突片状の単位歯31を周方向所定間隔をあけて所定数突設して構成している。 The ratchet mechanism is fitted and fixed in the first tooth group a on the closing plate 9 and the cap B 3 , and is engaged with the first tooth group a when the cap is screwed and is not engaged. And a second tooth group b. In the illustrated example, from a first tooth group a provided around the outer periphery of the columnar convex portion 11 projecting on the closing plate 9 and an inner surface of the fixed cylinder 30 fitted and fixed to the upper inner periphery of the peripheral wall 20 of the cap B 3. constitutes at the second teeth b which projects inwardly, thus, the first teeth a is formed integrally with the main body B 1, the second teeth b ratchet formation integral with the fixed barrel 30 The tooth member B 4 is formed separately from the main body B 1 and the cap B 3 . The first tooth group a is configured by connecting a predetermined number of triangular plate-shaped unit teeth 12 inclined in a predetermined direction to the outer periphery of the cylindrical convex portion 11, and the second tooth group b is inclined in a predetermined direction. The protruding piece-shaped unit teeth 31 are configured to protrude in a predetermined number with a predetermined interval in the circumferential direction.
固定筒30のキャップB3への嵌着固定は種々の形態を採用できるが、本例では、キャップ周壁20の内周上端部に周方向多数突設した縦突条23間に固定筒30の外周に周方向複数縦設した縦突条32を嵌着することにより充分な係合強度を得られる。キャップ側の縦突条23は所定間隔をあけて多数縦設しているのに対し、固定筒30側の縦突条32の数は少なく形成されており、また、両縦突条はそれぞれ等間隔に形成されている。 Various forms can be adopted for fixing and fixing the fixed cylinder 30 to the cap B 3 , but in this example, the fixed cylinder 30 is fixed between the vertical ridges 23 projecting in the circumferential direction on the inner peripheral upper end of the cap peripheral wall 20. Sufficient engagement strength can be obtained by fitting a plurality of longitudinal ridges 32 provided in the circumferential direction on the outer periphery. Whereas a large number of the vertical ridges 23 on the cap side are vertically arranged at a predetermined interval, the number of the vertical ridges 32 on the fixed cylinder 30 side is small, and both the vertical ridges are equal to each other. It is formed at intervals.
本発明ではキャップ螺着後の加熱処理により前記第２歯群ｂが硬化する如く構成している。この様な構成により、キャップ螺着時には第２歯群ｂが柔らかい状態であるため第１歯群ａを容易に乗り越えてキャップB3を螺着することができる。一方、螺脱する際には第２歯群ｂは硬化しているため、第１歯群ａとしっかり歯合し、確実に薄肉破断部８を切断して開封することができる如く構成している。 In the present invention, the second tooth group b is hardened by the heat treatment after the cap is screwed. With such a configuration, since the second tooth group b is in a soft state when the cap is screwed, the cap B 3 can be screwed easily over the first tooth group a. On the other hand, since the second tooth group b is hardened when the screw is unscrewed, the second tooth group b is firmly engaged with the first tooth group a so that the thin fracture portion 8 can be surely cut and opened. Yes.
この様に構成するためには、例えば第２歯群ｂを構成する部材であるラチェット形成用の歯部材B4を結晶性樹脂により形成し、該結晶性樹脂の結晶化開始温度以上の温度で前記加熱処理を行う。この場合加熱処理温度は融点未満の範囲で行う。結晶化開始温度は成形時の樹脂が固化する環境例えば冷却速度によって変化するが示差操作式熱量計による熱量分析等を行うことにより知ることができる。結晶性樹脂として、種々の熱可塑性樹脂が採用できるが、ポリエチレンテレフタレートが螺着時には適度の柔軟性を現出し、加熱処理後に確実な歯合を発揮する硬度を現出することができるため特に好ましい。加熱処理は公知の種々の形態を採用できるが、通常の加熱殺菌処理形態を採用することにより、加熱殺菌処理と第２歯群ｂの硬化とを同時に行えるため好ましく、１００〜１５０℃の範囲で行うことが好ましい。一例として、ポリエチレンテレフタレートを使用し、レトルト条件（１２０℃，３０分間）で加熱殺菌を行うことにより、加熱殺菌処理と第２歯群ｂの硬化を同時に行うことができる。 In order to configure in this way, for example, a ratchet forming tooth member B 4 which is a member constituting the second tooth group b is formed of a crystalline resin, and at a temperature equal to or higher than the crystallization start temperature of the crystalline resin. The heat treatment is performed. In this case, the heat treatment temperature is within a range below the melting point. The crystallization start temperature varies depending on the environment in which the resin at the time of molding solidifies, for example, the cooling rate, but can be known by performing calorimetric analysis using a differential operation calorimeter. Various thermoplastic resins can be used as the crystalline resin, but polyethylene terephthalate is particularly preferable because it exhibits moderate flexibility when screwed and can exhibit hardness that exhibits a reliable engagement after heat treatment. . Various known forms can be adopted for the heat treatment, but by adopting a normal heat sterilization treatment form, heat sterilization treatment and hardening of the second tooth group b can be performed at the same time, preferably in the range of 100 to 150 ° C. Preferably it is done. As an example, heat sterilization treatment and curing of the second tooth group b can be performed simultaneously by using polyethylene terephthalate and performing heat sterilization under retort conditions (120 ° C., 30 minutes).
尚、本発明に於いて第２歯群ｂを構成する部材であるラチェット形成用の歯部材B4以外のスパウトＢを構成する部材、即ち、本体部B1、キャップB3は結晶性樹脂で形成しても、非晶性樹脂で形成しても良い。図示例では、本体部B1及びキャップB3ともにポリプロピレンを採用している。この他高密度ポリエチレン等も好ましく使用できる。 In the present invention, members constituting the spout B other than the ratchet forming tooth member B 4 which is a member constituting the second tooth group b in the present invention, that is, the main body B 1 and the cap B 3 are made of crystalline resin. Alternatively, it may be formed of an amorphous resin. In the illustrated example, the main body B 1 and the cap B 3 are both made of polypropylene. In addition, high density polyethylene and the like can also be preferably used.
また、キャップ周壁20の内面所定位置に突周設したシール突条24を、キャップB3を螺着させた際に本体部B1の外周上端部に圧接させてシール機能を付与している。従ってこの場合には、その部分に於いてシール突条24の突出幅だけ両者に隙間が存在する。尚、シール機能を付与する具体的構成としてはこれに限られず、キャップB3内周面と本体部B1外周面とを面接触させて圧接しても良いが、後述する拡開手段を設ける場合には上記隙間がある方が拡開手段がより機能し易い。 Also, the sealing protrusion 24 which is circular projection set on the inner surface a predetermined position of the cap wall 20, is imparted a sealing function by pressing the outer peripheral upper end portion of the main body portion B 1 when the cap B 3 is screwed. Therefore, in this case, there is a gap in both portions by the protruding width of the seal protrusion 24 at that portion. The specific configuration for providing the sealing function is not limited to this, and the inner peripheral surface of the cap B 3 and the outer peripheral surface of the main body B 1 may be brought into pressure contact with each other, but an expanding means described later is provided. In some cases, the expanding means is more likely to function if there is a gap.
