Description
本考案は、使い切った内容物を補充可能な包装用容器に使用される中栓、及び当該中栓を備えた包装容器に関する。 The present invention relates to an inner stopper used for a packaging container capable of replenishing a used content, and a packaging container provided with the inner stopper.
液体化粧品や液体調味料等を内部に収容する包装容器には、内容物を使い切った際に中栓を取り外して内容物を補充することができるものがある（特許文献１、特許文献２参照）。 Some packaging containers containing liquid cosmetics, liquid seasonings, and the like can remove the inner plug and replenish the contents when the contents are used up (see Patent Documents 1 and 2). .
このような包装容器の中栓は、包装容器の口部と螺合係合しているため着脱が容易である一方、中栓は包装容器の口部外側を覆うように係合されているため、内容物を補充しやすいように包装容器の口部内径を大きくしようとすると、中栓の外径はそれより更に大きくなってしまい、包装容器全体のバランスが悪くなる。これに対し、包装容器全体のバランスを考慮して中栓の外径を大きくなり過ぎないように調整すると、包装容器の口部内径が小さくなってしまい、内容物の補充作業がやりづらくなる問題が生じてしまう。 The inner plug of such a packaging container is easy to attach and detach because it is screwed into the mouth of the packaging container, while the inner plug is engaged to cover the outside of the opening of the packaging container. If the inner diameter of the mouth of the packaging container is increased so that the contents can be easily replenished, the outer diameter of the inner plug becomes larger than that, and the balance of the entire packaging container is deteriorated. On the other hand, if the inner diameter of the inner plug is adjusted so as not to be too large in consideration of the balance of the entire packaging container, the inner diameter of the mouth of the packaging container becomes small, and it becomes difficult to refill the contents. Will occur.
また、使用者が中栓を取り外す際には中栓の外周を摘まんでネジ係合を緩める必要があるが、特許文献１、特許文献２に記載の従来技術は、中栓と外キャップがネジ係合しているため、使用者の指は中栓のネジ山が回転方向に当たるために滑りやすく、更に、包装容器の口部外側にネジが現れるため見た目が悪い（外観が悪い）とともに、内容物を抽出した際に誤って内容物が流れ出た場合、液体がネジに付着してネジの凹部に入り込み、拭き取り清掃を必要とし、面倒であると言う問題があった。 Further, when the user removes the inner plug, it is necessary to pinch the outer periphery of the inner plug and loosen the screw engagement. However, in the conventional techniques described in Patent Documents 1 and 2, the inner plug and the outer cap are screwed. Because of the engagement, the user's finger is slippery because the screw thread of the inner stopper hits in the rotation direction, and furthermore, a screw appears on the outside of the mouth of the packaging container, so that the appearance is poor (poor appearance) and the content is also poor. If the contents erroneously flow out when the material is extracted, there is a problem that the liquid adheres to the screw and enters the recess of the screw, necessitating wiping and cleaning, which is troublesome.
本考案は、包装容器本体に対して中栓の着脱が容易で、内容物の補充がし易く、また包装容器の口部外側にネジ構造が現れないため見た目がすっきりと美しくなるとともに、内容物がこぼれ出た際の容器の拭き取り清掃が容易となる中栓、及び当該中栓を備えた包装容器を提供することを目的とする。 The present invention makes it easy to attach and detach the inner stopper to and from the packaging container body, to easily replenish the contents, and to make the appearance clear and beautiful because the screw structure does not appear outside the mouth of the packaging container. An object of the present invention is to provide an inner plug that facilitates wiping and cleaning of a container when spilled out, and a packaging container provided with the inner plug.
上記目的を達成するため、本願の第一の考案は、円筒形の口部を有する包装容器本体に対し、当該口部の内周面に形成した雌ネジ又は雄ネジを介して係脱可能な中栓であって、前記中栓は、天面部に内容物を排出するための排出孔を有する筒状体であり、下部外周に、前記包装容器本体の雌ネジ又は雄ネジと係合する雄ネジ又は雌ネジを有し、上部外周に、外キャップを係合するための係合手段が設けられている、ことを特徴とする。 In order to achieve the above object, a first invention of the present application is that the container can be disengaged from a packaging container body having a cylindrical mouth via a female screw or a male screw formed on an inner peripheral surface of the mouth. An inner plug, wherein the inner plug is a cylindrical body having a discharge hole for discharging the contents to a top surface portion, and a male screw engaging with a female screw or a male screw of the packaging container body on a lower outer periphery. It has a screw or a female screw, and an engaging means for engaging the outer cap is provided on the upper outer periphery.
さらに、本願の第二の考案は、円筒形の口部を有する包装容器本体と、当該口部の内周面に形成した雌ネジ又は雄ネジを介して前記包装容器本体に係脱可能な中栓と、前記中栓に係脱可能な円筒形の外キャップと、を備えた包装用容器であって、前記中栓は、上記第一の考案に係る中栓であり、前記外キャップは、内周面に前記中栓の前記係合手段と係合する他方係合手段を有し、かつ天面の内側に前記中栓の前記排出孔を密封する栓部を有する、ことを特徴とする。 Further, a second invention of the present application is a packaging container main body having a cylindrical mouth portion, and a package container main body having a cylindrical opening, which can be disengaged from the packaging container main body via a female screw or a male screw formed on an inner peripheral surface of the mouth portion. A container for packaging comprising a stopper and a cylindrical outer cap detachable from the inner stopper, wherein the inner stopper is the inner stopper according to the first invention, and the outer cap is An inner peripheral surface has other engaging means for engaging with the engaging means of the inner plug, and a plug portion for sealing the discharge hole of the inner plug is provided inside the top surface. .
本考案によれば、包装容器本体の口部内面側にネジ構造を設けることで、口部外側に中栓とのネジを有する従来構造と比べて、美しくすっきりとした口部を構成することができ、かつ包装容器の口部内径を広くすることで、内容物の補充を容易に行うことができる。 According to the present invention, by providing the screw structure on the inner surface side of the mouth of the packaging container body, compared with the conventional structure having the screw with the inner plug on the outside of the mouth, it is possible to configure a beautiful and clean mouth. The contents can be easily refilled by increasing the inner diameter of the mouth of the packaging container.
また、本考案によれば、包装容器本体の口部に中栓を係合させた状態であっても、口部の外周面にネジ構造の凹凸が無いため、内容物が口部の外周面に流れ出たとしても、拭き取り清掃を容易に行うことができる。 Further, according to the present invention, even when the inner plug is engaged with the mouth of the packaging container main body, there is no unevenness of the screw structure on the outer periphery of the mouth, so that the content is the outer periphery of the mouth. Wiping and cleaning can be performed easily.
以下、本願考案の実施形態につき、図面を参照しながら詳細に説明する。
図１は、包装容器本体１、外キャップ２、中栓３によって構成される包装容器の全体外観図、及び断面図である。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall external view and a cross-sectional view of a packaging container constituted by a packaging container body 1, an outer cap 2, and an inner plug 3.
図示のごとく、包装容器本体１はその上部に円筒形の口部１１を有し、当該口部１１の内周面には雌ネジが形成されており、当該雌ネジを介して中栓３が包装容器本体１に対して係脱可能に係合されており、また中栓３には外キャップ３が係脱可能に係合している。 As shown in the figure, the packaging container body 1 has a cylindrical mouth 11 at an upper part thereof, and a female screw is formed on the inner peripheral surface of the mouth 11, and the inner plug 3 is inserted through the female screw. The outer cap 3 is removably engaged with the inner body 3 of the packaging container body 1.
図２は、外キャップ２の側面図、断面図、底面図を示す図であり、外キャップ２の天面の内側中央には、中栓３の排出孔（後述）を封鎖して密封する栓部２３が突出形成されている。また、外キャップ２の内周面２１には、中栓３に形成される係合凸部（後述）に係合する雌ネジ２２が形成されている。 FIG. 2 is a view showing a side view, a cross-sectional view, and a bottom view of the outer cap 2. At the center inside the top surface of the outer cap 2, a stopper for closing and sealing a discharge hole (described later) of the inner stopper 3. The part 23 is formed so as to protrude. A female screw 22 is formed on the inner peripheral surface 21 of the outer cap 2 so as to engage with an engaging projection (described later) formed on the inner plug 3.
さらに、外キャップ２の内周面の下部には、中栓に形成する位置決め凸部（後述）を弾性的に乗り越える乗越リブ２４が設けられており、さらに乗越リブ２４の側方には、上記位置決め凸部と当接して外キャップ３の回転位置を規制するためのストッパー２５が設けられている。 Further, a riding-over rib 24 is provided below the inner peripheral surface of the outer cap 2 to resiliently ride over a positioning projection (described later) formed on the inner plug. A stopper 25 is provided for abutting the positioning projection to regulate the rotational position of the outer cap 3.
図３は、中栓３の断面図及び底面図である。中栓３は、全体として筒状体であり、その天面部に内容物を排出するための排出孔３３を有し、下部外周には包装容器本体１の雌ネジと係合する雄ネジが形成され、また上部外周には外キャップを係合するための係合凸部３２（係合手段）が設けられている。 FIG. 3 is a sectional view and a bottom view of the inner plug 3. The inner stopper 3 is a cylindrical body as a whole, has a discharge hole 33 for discharging the contents on the top surface thereof, and a male screw which engages with the female screw of the packaging container body 1 is formed on the outer periphery of the lower part. The upper outer periphery is provided with an engaging projection 32 (engaging means) for engaging the outer cap.
中栓３の上部外周と下部外周との間（境目）には、筒状体の径方向外側に突出する環状リブ３６が形成されており、図１に示すとおり、当該環状リブ３６の下面は包装容器本体１の口部１１の先端に当接して封鎖し、当該環状リブ３６の上面は外キャップ２の下端に当接するようになっている。 An annular rib 36 projecting radially outward of the cylindrical body is formed between the upper outer periphery and the lower outer periphery (boundary) of the inner plug 3, and as shown in FIG. The top surface of the annular rib 36 is in contact with the lower end of the outer cap 2 by abutting on the tip of the mouth 11 of the packaging container body 1 to close the mouth.
また、環状リブ３６の上面には、外キャップ２をネジ込んだ際の位置決め凸部３４が形成されている。 On the upper surface of the annular rib 36, a positioning projection 34 when the outer cap 2 is screwed is formed.
さらに中栓３の内周面には、縦方向に２本の縦リブ３５が形成されており、当該縦リブ３５によって中栓３の剛性が向上すると共に、中栓３に外キャップ２を係合させる際に、冶具等で縦リブ３５を保持すれば外キャップ２と中栓３とを容易かつしっかりと固定することができる。なお、縦リブ３５は少なくとも１本あれば良く、その数、形成する位置は特に限定されない。 Further, two vertical ribs 35 are formed on the inner peripheral surface of the inner plug 3 in the vertical direction, and the rigidity of the inner plug 3 is improved by the vertical ribs 35, and the outer cap 2 is engaged with the inner plug 3. At the time of joining, if the vertical ribs 35 are held by a jig or the like, the outer cap 2 and the inner plug 3 can be easily and firmly fixed. Note that at least one vertical rib 35 may be used, and the number and position of the vertical rib 35 are not particularly limited.
上記実施形態において、中栓３の下部外周には、包装容器本体１の口部に形成された雌ネジに対して係合するように雄ネジを形成する例を示したが、包装容器本体１の口部に雄ネジを形成し、当該雄ネジに対して雌ネジで係合するようにしても良い。 In the above-described embodiment, an example is shown in which a male screw is formed on the outer periphery of the lower portion of the inner plug 3 so as to engage with a female screw formed at the mouth of the packaging container body 1. A male screw may be formed at the mouth of the connector and the female screw may be engaged with the male screw.
上記のとおり、包装容器本体１と中栓３は、互いに雄ネジと雌ネジの関係で強固にネジ係合する一方、外キャップ２と中栓３は、雌ネジと凸部の関係で係合するため、包装容器本体１と中栓３とのネジ係合力は、中栓３と外キャップ２との係合力よりも強く設定することができ、外キャップ２を回して外す際に、中栓３が供回りして包装容器本体１から外れてしまうことを防止することができる。 As described above, the packaging container body 1 and the inner plug 3 are tightly engaged with each other in a relationship of a male screw and a female screw, while the outer cap 2 and the inner plug 3 are engaged in a relationship of a female screw and a projection. Therefore, the screw engaging force between the packaging container body 1 and the inner cap 3 can be set to be stronger than the engaging force between the inner cap 3 and the outer cap 2. 3 can be prevented from rotating and coming off the packaging container body 1.
さらに、包装容器本体１と中栓３とのネジ方向と、中栓３と外キャップ２とのネジ方向を逆にすれば、外キャップ２を回して外す際に、中栓３が供回りして包装容器本体１から外れてしまうことを確実に防止することができる。 Further, if the screw direction between the packaging container body 1 and the inner cap 3 and the screw direction between the inner cap 3 and the outer cap 2 are reversed, the inner cap 3 rotates when the outer cap 2 is turned off. Thus, it is possible to reliably prevent the package container 1 from coming off the packaging container body 1.
なお、外キャップ２と中栓３は、ネジ式による係合ではなく、外キャップの内側面と中栓３の外側面とによる圧入式であっても良い。圧入式にした場合、中栓３の共回りをより防止することができる。 Note that the outer cap 2 and the inner plug 3 may be of a press-fit type using the inner surface of the outer cap and the outer surface of the inner plug 3 instead of the screw type engagement. In the case of the press-fit type, the co-rotation of the inner plug 3 can be further prevented.
図４〜１０は、中栓３の構造に係る実施形態１〜７を示す図である。
図４は実施形態１の構造を示したものであり、断面円形の係合凸部３２が、互いに１８０度反対方向に２カ所設けられ、位置決め凸部３４が１カ所だけ設けられている。また雄ネジ３１の一部には膨出部３７が形成されており、包装容器本体１の口部１１の内面に形成された雌ネジと強固にネジ係合できるようになっている。さらに、雄ネジ３１の上方位置には、包装容器本体１の口部１１の内周面と密着する環状凸部３８が設けられている。この構成によれば、包装容器本体１に対する中栓の密封性を更に向上させることが出来る。なお、膨出部３７は、容器本体１の口部１１の内面に形成された雌ネジに形成しても良く、また雄ネジ及び雌ネジの両方に形成しても良い。
4 to 10 are diagrams showing Embodiments 1 to 7 relating to the structure of the inner plug 3.
FIG. 4 shows the structure of the first embodiment, in which two engaging projections 32 having a circular cross section are provided in two directions 180 degrees opposite to each other, and only one positioning projection 34 is provided. A bulging portion 37 is formed in a part of the male screw 31 so that the male screw 31 can be securely engaged with a female screw formed on the inner surface of the mouth 11 of the packaging container body 1. Further, an annular convex portion 38 is provided at a position above the male screw 31 so as to be in close contact with the inner peripheral surface of the mouth portion 11 of the packaging container body 1. According to this configuration, the sealing property of the inner plug with respect to the packaging container body 1 can be further improved. The bulging portion 37 may be formed in a female screw formed on the inner surface of the mouth portion 11 of the container body 1, or may be formed in both a male screw and a female screw.
図５は実施形態２の構造を示す図であり、実施形態１との相違は、図示するように断面円形の係合凸部３２が、互いに９０度の間隔を持って４カ所設けられ、位置決め凸部３４が互いに１８０度反対方向に２カ所設けられている点である。この構成によれば、中栓３に対する外キャップ２の係合がより容易になるとともに、外キャップ２の位置決めも確実にすることができる。 FIG. 5 is a view showing the structure of the second embodiment. The difference from the first embodiment is that, as shown in the figure, four engaging projections 32 having a circular cross section are provided at intervals of 90 degrees from each other. The point is that two convex portions 34 are provided in directions opposite to each other by 180 degrees. According to this configuration, the engagement of the outer cap 2 with the inner plug 3 becomes easier, and the positioning of the outer cap 2 can be ensured.
図６は実施形態３の構造を示す図であり、実施形態１との相違は、図示するように係合凸部３２の断面形状が楕円形であり、外キャップ２の雌ネジの傾斜に沿って斜めになっている点である。この構成によれば中栓３に対する外キャップ２の係合がより容易になる。 FIG. 6 is a view showing the structure of the third embodiment.

図７は実施形態４の構造を示す図であり、実施形態３との相違は、図示するように係合凸部３２の断面形状が４つの頂点が円弧状になった平行四辺形であり、外キャップ２の雌ネジの傾斜に沿って斜めに形成されている点である。この構成によれば中栓３に対する外キャップ２の係合がより容易になるとともに、係合凸部３２の強度を高め、外部応力によって容易に破損してしまうことを防止することができる。 FIG. 7 is a view showing the structure of the fourth embodiment. The difference from the third embodiment is that the cross-sectional shape of the engaging projection 32 is a parallelogram in which four vertexes are arc-shaped, as shown in FIG. This is a point formed obliquely along the inclination of the female screw of the outer cap 2. According to this configuration, the engagement of the outer cap 2 with the inner plug 3 becomes easier, and the strength of the engagement projection 32 can be increased to prevent the inner projection 3 from being easily damaged by external stress.
図８は実施形態５の構造を示す図であり、実施形態１との相違は、図示するように断面円形の係合凸部３２が、互いに１２０度の間隔を持って３カ所に設けられており、そのうち２カ所の係合凸部３２には、ネジ方向の傾斜面が形成されている点である。この構成によれば、中栓３に対する外キャップ２の係合がより容易になる。 FIG. 8 is a view showing the structure of the fifth embodiment. The difference from the first embodiment is that, as shown in the figure, engagement protrusions 32 each having a circular cross section are provided at three places with an interval of 120 degrees from each other. One of the points is that two of the engaging projections 32 are formed with inclined surfaces in the screw direction. According to this configuration, the engagement of the outer cap 2 with the inner plug 3 becomes easier.
図９は実施形態６の構造を示す図であり、実施形態１との相違は、図示するように互いに１８０度反対方向に設けられている断面円形の係合凸部３２が、それぞれ上下２段に設けられており、合計４カ所に係合凸部３２が形成されている点である。この構成によれば、中栓３に対する外キャップ２の係合がより容易になるとともに、外キャップ２のガタつきをより抑えることができる。 FIG. 9 is a view showing the structure of the sixth embodiment. The difference from the first embodiment is that engagement protrusions 32 having circular cross sections provided in directions opposite to each other by 180 degrees as shown in FIG.

図１０は実施形態７の構造を示す図であり、実施形態１との相違は、図示するように環状凸部３８が雄ネジ３１の上方位置及び下方位置の２カ所に形成されている点である。この構成によれば、包装容器本体１の口部１１の内周面との密封性を更に向上させることができる。 FIG. 10 is a view showing the structure of the seventh embodiment. The difference from the first embodiment is that, as shown in the drawing, an annular convex portion 38 is formed at two positions, an upper position and a lower position of the male screw 31. is there. According to this configuration, the sealing performance with the inner peripheral surface of the mouth 11 of the packaging container body 1 can be further improved.
上記各実施形態で説明したように、係合凸部３２の形状及び設置個所数、位置決め凸部３４の設置個所数、環状凸部３８の設置個所数は、それぞれ適宜に選択・設計することができ、特に限定されない。 As described in the above embodiments, the shape and the number of installation locations of the engagement projections 32, the number of installation locations of the positioning projections 34, and the number of installation locations of the annular projections 38 can be appropriately selected and designed. Yes, it is not particularly limited.
以上、本考案に係る包装容器によれば、包装容器本体１から中栓３を取り外し、または包装容器本体１に中栓３を取り付ける際、従来構造では中栓外周に形成されたネジを指で摘んで回転させる必要があるため、ネジ山と回転方向が同じ方向となり、思うように中栓３を回転させることができなかったが、本考案の中栓３は、包装容器本体１の口部から突出した位置にある係合凸部、及び／又は位置決め凸部に指をひっかけることによって、容易に回転させることができる。 As described above, according to the packaging container according to the present invention, when removing the inner plug 3 from the packaging container main body 1 or attaching the inner plug 3 to the packaging container main body 1, the screw formed on the outer periphery of the inner plug in the conventional structure is finger-operated. Since it was necessary to pinch and rotate, the screw thread and the rotation direction were the same direction, and the inner plug 3 could not be rotated as desired. By hooking a finger on the engaging protrusion and / or the positioning protrusion located at a position protruding from the, it can be easily rotated.
また、中栓の係合凸部と外キャップの雌ネジとの係合による場合、中栓３から外キャップ２を取り外す際、従来のネジによる係合に比べて、係合凸部と雌ネジとの接触面積が小さい分摩擦抵抗が小さく、外キャップの取り外しが容易で、かつ中栓の供回りを防止することができる。 In the case where the outer cap 2 is detached from the inner plug 3 in the case where the engagement protrusion of the inner plug is engaged with the female screw of the outer cap, the engagement protrusion and the female screw are compared with the conventional screw engagement. The frictional resistance is small due to the small contact area with the outer cap, the outer cap can be easily removed, and the rotation of the inner plug can be prevented.
また中栓３と外キャップ２を係合した状態で、中栓３と外キャップ２が相互に回動しないように中栓３及び外キャップ２に位置決め構造が設けられているため、先に中栓３と外キャップ２を係合した状態のものを作成しておき、包装容器本体１へ内容物を充填後、中栓３と外キャップ２との係合品を包装容器本体１に装着するだけで包装容器の密封が完了でき、作業工程の削減に貢献できる。 Also, since the inner plug 3 and the outer cap 2 are provided with a positioning structure so that the inner plug 3 and the outer cap 2 do not rotate with each other in a state where the inner plug 3 and the outer cap 2 are engaged, A product in which the stopper 3 and the outer cap 2 are engaged is prepared, and after filling the contents into the packaging container main body 1, the engaged product of the inner plug 3 and the outer cap 2 is attached to the packaging container main body 1. This alone can complete the sealing of the packaging container, which can contribute to the reduction of work processes.
