Description

本発明は、開口部が大きな広口容器本体とそれに使用するキャップとからなる密封容器に関する。   The present invention relates to a sealed container including a wide-mouth container main body having a large opening and a cap used for the main body.

湿気を嫌う煎餅やビスケット、海苔、昆布などの食品や、各種の錠剤などの薬剤については、密封性の高い容器に入れて、容器と共に販売する方法が採られる。
この、内容物と共に提供される容器は、従来、開口部と胴部とからなるボトル形態の容器本体に対して、開口部に嵌めるキャップとの嵌合において、密封性を高めることが必要である。
特に、包装袋のような、内容物を一度に開封して使いきるのではなく、必要に応じて度々内容物を取り出すには、使用する都度開封し、取り出し後、密封性が高いキャップを閉めることができるボトルが必要で、再封鎖後にも、高い密封性を有する容器にすることによって、内容物の劣化を防止することで対応していた。
このような、密封性が高い容器にするには、容器本体の開口部先端に当接するキャップの嵌合当接部近傍に、軟質のパッキンや押圧変形可能なシールなどを貼る方法が一般的である。 For foods such as rice crackers, biscuits, seaweed, kelp, etc. that dislike moisture, and drugs such as various tablets, a method of selling them in containers with high sealing properties is adopted.
Conventionally, the container provided together with the contents needs to improve the sealing performance in the fitting with the cap fitted into the opening with respect to the bottle-shaped container main body composed of the opening and the trunk. .
In particular, instead of opening and using the contents at once, such as a packaging bag, in order to take out the contents as often as necessary, open it every time you use it, and then close the cap with high sealing performance after taking it out. A bottle that can be used is necessary, and even after re-sealing, the container has a high sealing property to prevent deterioration of the contents.
In order to make a container having such a high sealing property, a method of sticking a soft packing or a seal that can be deformed by pressure in the vicinity of the fitting contact portion of the cap that contacts the tip of the opening of the container body is generally used. is there.

この為、パッキンが外れたりしないように、キャップにパッキン等を粘着剤やホットメルト接着剤で固定したりする工程が必要になり、単一素材ではなくなると共に、高価になってしまう問題があった。   For this reason, there is a problem that the process of fixing the packing or the like to the cap with an adhesive or a hot melt adhesive is necessary so that the packing does not come off, and it becomes a single material and becomes expensive. .

以上の問題に対し、特許文献１ではキャップ天面内側に、板状のパッキンを嵌入し、パッキンの周縁部下面に、容器注出口先端当接する当接面を設けている。このパッキンの周縁ではキャップと嵌合する嵌合部を設けて、キャップ開封時にも、パッキンがキャップに残る仕組みを提案している。   With respect to the above problem, in Patent Document 1, a plate-shaped packing is fitted inside the top surface of the cap, and a contact surface that contacts the tip of the container outlet is provided on the lower surface of the peripheral edge of the packing. A mechanism has been proposed in which a fitting portion that fits with the cap is provided at the periphery of the packing so that the packing remains on the cap even when the cap is opened.

しかしながら、剛性を要求されるキャップと、弾性を要求されるパッキンは、素材的に変更せざるを得ず、やはり、廃棄する場合に単一素材ではなくなり、分別が必要となる。さらに、広口の容器にする場合、口元をそのままブローピンで成形しようとすると、ブロー比が小さくなり過ぎて、安定した生産ができない。
この場合、図２で示すように、容器口先に、雫状の袋１４を成形する。ロータリーブロー成形では常に図２のような袋１４を加えた形状の金型に挟み、袋１４部分にブローピン３１を刺して圧縮空気等をブローする。
同じように、ダイレクト（レシプロ）ブロー成形でも、図４で示すように、広口のボトルでは、同じような袋１４を加えた形状にして成形し、後加工で袋１４を削除する必要がある。
この袋と開口部との間は、カッター３２によって後加工で切断する。しかし、後加工であるが故に、開口部上端面の仕上げ精度を高く維持することができない。この為、単に単体のキャップを製造する精度を上げようとしても、密封性は向上しにくく、密封性を高く保つには、より弾性のある発泡ポリエチレンや両面にポリプロピレンを貼った厚いパッキンを必要とする問題があった。 However, caps that require rigidity and packings that require elasticity must be changed in terms of materials, and again, when discarded, they are not a single material and need to be separated. Furthermore, in the case of making a wide-mouthed container, if the mouth is tried to be molded with a blow pin as it is, the blow ratio becomes too small and stable production cannot be performed.
In this case, as shown in FIG. 2, a bag-like bag 14 is formed at the container mouth. In the rotary blow molding, the bag 14 is always sandwiched between molds as shown in FIG. 2, and the blow pin 31 is inserted into the bag 14 to blow compressed air or the like.
Similarly, in direct (reciprocating) blow molding, as shown in FIG. 4, it is necessary to form a wide-bottle bottle into a shape with a similar bag 14 added, and to delete the bag 14 in post-processing.
The bag and the opening are cut by post-processing by the cutter 32. However, because of post-processing, the finishing accuracy of the upper end surface of the opening cannot be maintained high. For this reason, even when trying to increase the accuracy of manufacturing a single cap, the sealing performance is difficult to improve. To keep the sealing performance high, more elastic foamed polyethylene and thick packing with polypropylene on both sides are required. There was a problem to do.

実用新案登録第２５６５５６９号公報Utility Model Registration No. 265569

そこで、口元にパッキンを使用しなくても、防湿性の高い密封容器を提供することが本発明の課題である。   Therefore, it is an object of the present invention to provide a highly moisture-proof sealed container without using a packing at the mouth.

本発明の密封容器は、容器本体とキャップとからなり、
容器本体は、下方に胴部、上方に開口部、胴部上端から開口部先端にかけてキャップ嵌合部を有し、
キャップ嵌合部は、外周下方に凸状に形成された係止リングを有し、
キャップはキャップ嵌合部を覆うキャップ筒状部と、
キャップ筒状部上端から内側に張り出した天板と、
天板内側で上記キャップ筒状部に平行なインナーリングと、を有する容器であって、
キャップ筒状部下方内面全周が凹部で形成され前記係止リングと係止可能な係止嵌合部を有し、
上記係止嵌合部上方において、キャップ筒状部内面とインナーリング外面とが、それぞれ、少なくとも１箇所ずつ、全周状に当接可能な当接嵌合部を有することを特徴とする密封容器である。 The sealed container of the present invention comprises a container body and a cap,
The container main body has a trunk part at the bottom, an opening part at the top, and a cap fitting part from the top of the trunk part to the top of the opening part,
The cap fitting portion has a locking ring formed in a convex shape on the outer periphery lower side,
The cap is a cap cylindrical part that covers the cap fitting part, and
A top plate projecting inward from the upper end of the cap cylindrical portion;
An inner ring parallel to the cap cylindrical portion on the inner side of the top plate,
The cap cylindrical part lower inner circumference is formed with a recess and has a locking fitting part that can be locked with the locking ring,
A sealed container having an abutting fitting portion capable of abutting at least one location on each of the inner surface of the cap cylindrical portion and the outer surface of the inner ring above the locking fitting portion. It is.

本発明の密封容器は、パッキンを用いず、キャップと容器本体の形状によって高い密封性を確保することができる。
容器本体の開口部先端に当接して密封性を得るのではなく、開口部先端から下方のキャップ嵌合部の側面と、キャップ筒状部内側とインナーリング外側の間で当接、あるいは嵌合して、密封する。このことによって、容器本体の開口部上端仕上げ精度を高くしなくても、高い密封性が維持可能であると共に、パッキンやホットメルト材などの異種材料を用いる必要もなく、価格を低く抑えることができる。 The sealed container of the present invention can ensure high sealing performance by using the cap and the shape of the container body without using packing.
Rather than abutting against the opening end of the container body to obtain a sealing property, the side surface of the cap fitting part below the opening end, and the inner side of the cap cylindrical part and the outer side of the inner ring are brought into contact or fitted. And seal. This makes it possible to maintain high sealing performance without increasing the accuracy of the upper end finish of the opening of the container body, and to keep the price low without using dissimilar materials such as packing and hot melt materials. it can.

本発明の密封容器で、そのキャップを嵌合した状態を示す斜視図と、キャップの上蓋を開口した状態を示す斜視図である。It is the perspective view which shows the state which fitted the cap with the sealed container of this invention, and the perspective view which shows the state which opened the upper cover of the cap. 広口の容器本体を、ロータリーブロー成形する形態を示す縦断面図である。It is a longitudinal cross-sectional view which shows the form which carries out rotary blow molding of the container main body of a wide mouth. 本発明の密封容器で、その容器本体にキャップを嵌合した状態を示す口元近傍の縦断面図で、上蓋を閉じた状態の断面図と、キャップの上蓋を開口した状態を示す断面図である。In the sealed container of this invention, it is the longitudinal cross-sectional view of the mouth vicinity which shows the state which fitted the cap with the container main body, sectional drawing of the state which closed the upper cover, and sectional drawing which shows the state which opened the upper cover of the cap . 広口の容器本体を、ダイレクトブロー成形する形態を示す縦断面図である。It is a longitudinal cross-sectional view which shows the form which carries out the direct blow molding of the container body of a wide mouth.

以下、本発明の密封容器について、図を用いて詳細に説明する。
図１は、本発明の密封容器で、図１−１がキャップを容器本体に嵌合した状態を示す斜視図。図１−２が容器本体に嵌合したキャップの上蓋を開口した状態を示す斜視図である。この図で示すように、広口の容器は、開口部の径に対する胴部の径の比であるブロー比が１．５倍未満になりやすい。
このような広口容器は、そのままの形状でダイレクトブロー成形すると、パリソンが非常に太くなる。このことは、押出パリソンをブロー金型で挟んだ時に、ブローピンを打ち込むまでの間、金型にパリソンを保持し続けることが出来ない。
さらに、ブローによって拡張される体積が少なく、容器の胴部が厚肉のまま金型に密着して圧接せざるを得ない為、容易に冷却され難く、表面がダレたり、部分的に冷却ムラが発生しやすいなど、成形は不安定である。 Hereinafter, the sealed container of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a sealed container according to the present invention, in which FIG. FIG. 1-2 is a perspective view showing a state in which an upper lid of a cap fitted to a container body is opened. As shown in this figure, the wide-mouthed container tends to have a blow ratio that is a ratio of the diameter of the body to the diameter of the opening less than 1.5 times.
When such a wide-mouthed container is directly blow-molded as it is, the parison becomes very thick. This means that when the extruded parison is sandwiched between blow molds, the parison cannot be held in the mold until the blow pin is driven.
Furthermore, since the volume expanded by blowing is small and the body of the container is thick, it must be in close contact with the mold and pressed against it. Molding is unstable, such as being prone to occur.

この為、図２や図４で示すように、袋１４を開口部１２１の先に形成し、後で袋１４をカッターで切り取る必要がある。
この為、容器本体の加工自体は変更できないので、開口部上端面の仕上げ精度を高く維持することができない点から、開口部上端面に当接するパッキンではなく、その側面側に当接する密封方法を採った。 For this reason, as shown in FIGS. 2 and 4, it is necessary to form the bag 14 at the tip of the opening 121 and cut the bag 14 later with a cutter.
For this reason, since the processing itself of the container main body cannot be changed, a sealing method that abuts on the side surface, not the packing that abuts on the upper end surface of the opening, can be used because the finishing accuracy of the upper end surface of the opening cannot be maintained high. I took it.

図３は、本発明の密封容器で、その容器本体１にキャップ２を嵌合した状態を示す口元近傍の縦断面図である。
図３−１は上蓋を閉じた状態の断面図で、図３−２はその部分拡大図、図３−３はキャップの上蓋を開口した状態を示す断面図である。
本発明の密封容器は、容器本体１とキャップ２からなり、パッキンは使用しない。 FIG. 3 is a longitudinal sectional view of the vicinity of the mouth showing a state where the cap 2 is fitted to the container body 1 in the sealed container of the present invention.
FIG. 3A is a cross-sectional view showing a state in which the upper lid is closed, FIG. 3B is a partially enlarged view thereof, and FIG. 3C is a cross-sectional view showing a state in which the upper cover of the cap is opened.
The sealed container of the present invention comprises a container body 1 and a cap 2, and no packing is used.

容器本体１は、下方に胴部１１、上方に開口部１２１を有し、胴部上端から開口部先端にかけてキャップ嵌合部１２を有している。
容器本体１のキャップ嵌合部１２は、下方外周に凸状に形成された係止リング１２２と、係止リング１２２より上方外周に凸状に形成された外シールリング１２３と、内側の内周に凸状に形成された内シールリング１２４との少なくとも３つの凸状に形成されたリングを有している。 The container main body 1 has the trunk | drum 11 in the downward direction, the opening part 121 in the upper part, and has the cap fitting part 12 from the trunk | drum upper end to the opening part front-end | tip.
The cap fitting portion 12 of the container body 1 includes a locking ring 122 that is convex on the lower outer periphery, an outer seal ring 123 that is convex on the outer periphery above the locking ring 122, and an inner inner periphery. And an inner seal ring 124 formed in a convex shape and at least three rings formed in a convex shape.

また、キャップ２は、容器本体１の開口部１２１とキャップ嵌合部１２外周を覆うキャップ筒状部２１を有し、キャップ筒状部上端から内側に天板２２を有している。
天板２２内側に、キャップ筒状部２１に平行してキャップ嵌合部１２内側に挿嵌可能なインナーリング２３を有している。
また、キャップ筒状部２１下方内面全周に、キャップ嵌合部１２と係止可能な並行した帯状の凹部２１１１と凸部２１１２とからなる係止嵌合部２１１を有している。 Moreover, the cap 2 has the cap cylindrical part 21 which covers the opening part 121 and the cap fitting part 12 outer periphery of the container main body 1, and has the top plate 22 inside from the cap cylindrical part upper end.
On the inner side of the top plate 22, an inner ring 23 that can be inserted into the cap fitting portion 12 is provided in parallel with the cap cylindrical portion 21.
In addition, a locking fitting portion 211 including a parallel belt-like concave portion 2111 and a convex portion 2112 that can be locked with the cap fitting portion 12 is provided on the entire inner periphery of the lower side of the cap cylindrical portion 21.

容器本体１にキャップ２を嵌合させると、容器本体１のキャップ嵌合部１２が、キャップ筒状部２１とインナーリング２３との隙間に挿嵌する。
この時、キャップ筒状部２１の上方内面２１３に対し外シールリング１２３が当接し、
インナーリング２３外面に内シールリング１２４が当接する。
さらに、深く挿嵌すると、係止リング１２２が係止嵌合部２１１の帯状に形成された凸部２１１２を乗り越える。そして、帯状に形成された凹部２１１１に係止リング１２２が挿嵌する。 When the cap 2 is fitted to the container main body 1, the cap fitting portion 12 of the container main body 1 is inserted into the gap between the cap cylindrical portion 21 and the inner ring 23.
At this time, the outer seal ring 123 comes into contact with the upper inner surface 213 of the cap tubular portion 21,
The inner seal ring 124 contacts the outer surface of the inner ring 23.
Furthermore, when it is inserted deeply, the locking ring 122 gets over the convex portion 2112 formed in the band shape of the locking fitting portion 211. Then, the locking ring 122 is inserted into the recess 2111 formed in a band shape.

このようにして、キャップ筒状部２１上方内面２１３と容器本体のキャップ嵌合部１２、インナーリング２３外面と容器本体のキャップ嵌合部１２、および、凹部２１１１と係止リング１２２が、それぞれ、１箇所ずつ、全周状に当接し、合わせて側面方向の３箇所において、全周で当接するので、確実に密封することができる。   In this way, the upper inner surface 213 of the cap tubular portion 21 and the cap fitting portion 12 of the container body, the outer surface of the inner ring 23 and the cap fitting portion 12 of the container body, and the recess 2111 and the locking ring 122 are respectively Since the contact is made around the entire circumference one by one, and the entire contact is made at three places in the side surface direction, it can be surely sealed.

本発明の密封容器に使用する容器本体は、通常、押し出したポリエチレン樹脂などのパリソンをブロー成形し、開口部を切断して開口して製造することができる。特にロータリーブロー成形機で製造できるが、レシプロタイプのダイレクトブロー成形機でも製造可能である。
開口部は、キャップに挿嵌するために、ブロー成形した後に、仕上げた容器を使用することが出来るが、小口径の容器本体であっても使用可能である。
もちろん、ポリアミドなどを積層した多層押し出しパリソンを使用し、多層容器にしてもかまわない。
さらに、内シールリングの位置を調整すれば、口元を射出成形したインジェクションブロー成形、延伸ブロー成形、液体反応性樹脂を使用した浸漬成形法（ディッピング法）による容器本体であっても使用できる。
成形材料は、ポリエチレン、ポリプロピレン、エチレン・プロピレン共重合体、エチレン・酢酸ビニル共重合体、アクリロニトリル、ブタジエンなどを共重合させたスチレン、ポリエチレンテレフタレート、ポリフェニレンサイファイド、ポリカーボネート、なども使用できる。 The container main body used for the sealed container of the present invention can be usually produced by blow molding a parison such as an extruded polyethylene resin and cutting and opening the opening. In particular, it can be manufactured by a rotary blow molding machine, but can also be manufactured by a reciprocating type direct blow molding machine.
In order to insert the opening into the cap, a finished container can be used after blow molding, but even a small-diameter container body can be used.
Of course, it is also possible to use a multilayer extruded parison in which polyamide or the like is laminated to form a multilayer container.
Furthermore, if the position of the inner seal ring is adjusted, the container body can be used even by injection blow molding, stretch blow molding with a mouth injection molded, or immersion molding (dipping method) using a liquid reactive resin.
As the molding material, polyethylene, polypropylene, ethylene / propylene copolymer, ethylene / vinyl acetate copolymer, styrene copolymerized with acrylonitrile, butadiene, etc., polyethylene terephthalate, polyphenylene sulfide, polycarbonate, and the like can also be used.

本発明の密封容器に使用するキャップは、汎用の射出成形機によって製造することができる。
また、本発明の密封容器は打栓式のキャップになるので、図１に示すような、キャップ嵌合部の横断面が円形である必要は無く、長円形状、あるいは４隅に曲線を有する多角形形状であっても、横断面形状が全周で外側に凸状の形状であれば、どのような形状であっても対応できる。
ただ、横断面が円形でない場合、開栓しにくくなるので、側壁であるキャップ筒状部の肉厚を薄くするか、直鎖状低密度ポリエチレンなどのような柔軟性のある素材で成形したキャップにすることが好ましい。 The cap used for the sealed container of the present invention can be manufactured by a general-purpose injection molding machine.
Further, since the sealed container of the present invention is a cap-type cap, the cross section of the cap fitting portion does not need to be circular as shown in FIG. 1, and has an oval shape or curves at four corners. Even if it is a polygonal shape, any shape can be used as long as the cross-sectional shape is a convex shape on the entire circumference.
However, when the cross section is not circular, it is difficult to open the cap, so the cap cylindrical part that is the side wall is made thin, or the cap is made of a flexible material such as linear low-density polyethylene. It is preferable to make it.

さらに、本発明の密封容器に使用するキャップは、係止リング１２２や係止嵌合部２１１の形状によっては、容器本体から外し難くなるので、通常の内容物を取り出すには、図３のように、キャップの天板にキャップ開口孔２４を設け、キャップ筒状部の上端外側端部に、ヒンジ２６を介して開閉可能な上蓋２５を有するキャップが好ましい。
この上蓋２５には、開閉し易いように、ヒンジ反対側に係止部２７と、開口用鍔２８と、キャップ開口孔に挿嵌可能な上蓋インナーリング２９と、を設けると良い。 Furthermore, since the cap used for the sealed container of the present invention is difficult to remove from the container body depending on the shape of the locking ring 122 and the locking fitting portion 211, as shown in FIG. Further, a cap having a cap opening hole 24 in the top plate of the cap, and an upper lid 25 that can be opened and closed via a hinge 26 at the upper end outer end of the cap cylindrical portion is preferable.
The upper lid 25 is preferably provided with a locking portion 27, an opening hook 28, and an upper lid inner ring 29 that can be inserted into the cap opening hole on the opposite side of the hinge so as to be easily opened and closed.

キャップに使用される成形材料は、高密度ポリエチレン、直鎖状低密度ポリエチレン、ポリプロピレン、エチレン・プロピレン共重合体、エチレン・酢酸ビニル共重合体、アクリロニトリル・ブタジエン・スチレン共重合体、アクリロニトリル・スチレン共重合体、ブタジエン・スチレン共重合体、アクリロニトリル、ポリメチルペンテン、ポリオキシメチレンなどが使用できる。特にヒンジを介して回動可能な上蓋を有するキャップにするにはポリプロピレンやエチレン・プロピレン共重合体が好ましい。   Molding materials used for the cap are high density polyethylene, linear low density polyethylene, polypropylene, ethylene / propylene copolymer, ethylene / vinyl acetate copolymer, acrylonitrile / butadiene / styrene copolymer, acrylonitrile / styrene copolymer. Polymers, butadiene / styrene copolymers, acrylonitrile, polymethylpentene, polyoxymethylene and the like can be used. In particular, polypropylene or an ethylene / propylene copolymer is preferable for a cap having an upper lid that can be rotated via a hinge.

本発明の密封容器は、以上のようなもので、キャップ嵌合部とキャップとの間の全周囲３箇所で当接するので、パッキンを用いないにもかかわらず、キャップと容器本体の形状によって高い密封性を確保することができる。
しかも、容器本体の開口部先端に当接して密封性を得るのではなく、開口部先端から下方のキャップ嵌合部の側面と、キャップ筒状部内側とインナーリング外側の間で当接、あるいは嵌合して、密封する。このことによって、容器本体の開口部上端仕上げ精度が高くなくても、高い密封性が維持可能である。それと共に、パッキンやホットメルト材などの異種材料を用いる必要もないので、単一素材となり、低価格で量産性も高いなど、本発明のメリットは大きい。 The sealed container of the present invention is as described above, and abuts at three places around the entire circumference between the cap fitting portion and the cap, so that the height is high depending on the shape of the cap and the container main body even though no packing is used. Sealability can be secured.
Moreover, it does not contact the opening tip of the container body to obtain a sealing property, but abuts between the side surface of the cap fitting portion below the opening tip and the inside of the cap cylindrical portion and the outside of the inner ring, or Mate and seal. Thereby, even if the upper end finishing accuracy of the container main body is not high, high sealing performance can be maintained. At the same time, since there is no need to use different materials such as packing and hot melt material, the advantages of the present invention are great, such as a single material, low price and high mass productivity.
