Description

本発明は、有底筒状とされた容器本体の口部に、この容器本体の内部と連通可能な注出口を有するキャップが設けられたキャップ付き容器に関するものである。   The present invention relates to a container with a cap provided with a cap having a spout that can communicate with the inside of the container body at the mouth of the container body having a bottomed cylindrical shape.

この種のキャップ付き容器に設けられるキャップとして、例えば下記特許文献１に示されるような、容器本体の口部に取り付けられた内栓と、この内栓に着脱可能に設けられ、かつ前記注出口を有するキャップ本体とを備えた構成が知られている。そして、このキャップ付き容器においては、需要者に、キャップ本体が内栓から取り外されたことがあるか否かを示すために、キャップ全体、若しくはキャップ付き容器全体に樹脂フィルムを被覆して販売されることがある。
特開平１１−１３０１２３号公報 As a cap provided in this type of cap-equipped container, for example, as shown in Patent Document 1 below, an inner stopper attached to the mouth of the container main body, a detachably provided inner stopper, and the spout The structure provided with the cap main body which has this is known. And in this container with a cap, in order to indicate to the consumer whether or not the cap body has been removed from the inner stopper, the entire cap or the entire container with the cap is covered with a resin film and sold. Sometimes.
JP-A-11-130123

しかしながら、このように樹脂フィルムで被覆するとキャップ付き容器の製造コストを増大させるおそれがあった。   However, such a coating with a resin film may increase the manufacturing cost of a container with a cap.

本発明は、このような事情を考慮してなされたもので、製造コストの増大を抑えつつ、キャップ本体が内栓から取り外されたことがあるか否かを需要者に示すことができるキャップ付き容器を提供することを目的とする。   The present invention has been made in consideration of such circumstances, and with a cap that can indicate to the consumer whether or not the cap body has been removed from the inner plug while suppressing an increase in manufacturing cost. The purpose is to provide a container.

上記課題を解決して、このような目的を達成するために、本発明のキャップ付き容器は、 有底筒状とされた容器本体の口部に、この容器本体の内部と連通可能な注出口を有するキャップが設けられ、このキャップは、前記口部に取り付けられた内栓と、この内栓に着脱可能に設けられ、かつ前記注出口を有するキャップ本体とを備えたキャップ付き容器であって、前記内栓は、前記口部の内周面に嵌合する第１筒部と、この第１筒部よりも大径とされ、かつ前記口部の外周面に支持される第２筒部とを備え、前記キャップ本体の周壁部に係合し、かつ前記第２筒部の外周面に連結片を介して連結されたリング部材が備えられ、前記連結片は、前記周壁部に前記リング部材を係合した状態で、前記キャップ本体を前記内栓に対して前記容器本体の中心軸線方向上方に移動させたときに作用する引張力で破断可能とされていることを特徴とする。
この発明によれば、キャップ本体を内栓に対して上方に移動させると、その周壁部に係合された前記リング部材も上方に移動させられる。一方、前記連結片は、容器本体の口部に取り付けられた内栓の前記第２筒部の外周面に連結されているので、前述したリング部材の上方に向けた移動により引張され、キャップ本体が内栓から取り外される過程で破断することになる。
したがって、連結片が破断されてキャップ本体が一度でも内栓から取り外されると、その後に、このキャップ本体を再度内栓に取り付けたとしても、少なくともリング部材は前記中心軸線回りに回転自在となるので、キャップ本体が内栓から取り外されたことがあるか否かを需要者に示すことができる。しかも、樹脂フィルムを用いないので、このキャップ付き容器の製造コストの増大を抑えることもできる。 In order to solve the above problems and achieve such an object, a container with a cap according to the present invention has a spout that can communicate with the inside of the container body at the mouth of the container body that has a bottomed cylindrical shape. A cap having an inner plug attached to the mouth portion and a cap body detachably provided on the inner plug and having the spout. The inner plug has a first cylinder part fitted to the inner peripheral surface of the mouth part, and a second cylinder part having a larger diameter than the first cylinder part and supported by the outer peripheral surface of the mouth part. A ring member that engages with a peripheral wall portion of the cap body and is connected to an outer peripheral surface of the second cylindrical portion via a connecting piece, and the connecting piece is connected to the peripheral wall portion of the ring. In a state where the members are engaged, the cap main body is connected to the inner plug with respect to the inner cap. It can be ruptured by a tensile force acting when it is moved upward in the central axis direction.
According to this invention, when the cap main body is moved upward with respect to the inner plug, the ring member engaged with the peripheral wall portion is also moved upward. On the other hand, since the connecting piece is connected to the outer peripheral surface of the second cylindrical portion of the inner plug attached to the mouth portion of the container main body, it is pulled by the upward movement of the ring member described above, and the cap main body Will break in the process of being removed from the inner plug.
Therefore, when the connecting piece is broken and the cap body is once removed from the inner plug, even if the cap body is attached to the inner plug again, at least the ring member can rotate around the central axis. It is possible to indicate to the consumer whether or not the cap body has been removed from the inner plug. And since the resin film is not used, the increase in the manufacturing cost of this container with a cap can also be suppressed.

ここで、前記内栓、連結片およびリング部材は、前記キャップ本体を形成する材質よりも破断強度の低い材質で一体的に形成されてもよい。
この場合、内栓、連結片およびリング部材が、キャップ本体を形成する材質よりも破断強度の低い材質で一体的に形成されているので、前記周壁部にリング部材を係合した状態で、キャップ本体を内栓に対して上方に移動させたときに、前記連結片を容易に破断することが可能になる。また、内栓、連結片およびリング部材が一体的に形成されているので、これらを容易に形成することが可能になり、キャップ付き容器の製造コストの増大を確実に抑えることができる。 Here, the inner plug, the connecting piece, and the ring member may be integrally formed of a material having a lower breaking strength than a material forming the cap body.
In this case, since the inner plug, the connecting piece and the ring member are integrally formed of a material having a lower breaking strength than the material forming the cap body, the cap is engaged with the ring member engaged with the peripheral wall portion. When the main body is moved upward with respect to the inner plug, the connecting piece can be easily broken. Moreover, since the inner plug, the connecting piece, and the ring member are integrally formed, they can be easily formed, and an increase in the manufacturing cost of the capped container can be reliably suppressed.

また、前記リング部材には、その周方向に間隔をあけて複数の切込みが形成されてもよい。
この場合、前述のようにキャップ本体を上方に移動させたときに、前記連結片だけでなく、リング部材をも破断させることが可能になり、キャップ本体が内栓から取り外されたことがあるか否かを需要者に一層明確に示すことができる。さらに、未開封のキャップ付き容器を開封する際にリング部材が破断されるので、このように一旦開封した後は、このリング部材をキャップ本体から容易に取り除くことが可能になり、リング部材を設けたことによりキャップ付き容器の使い勝手や見映えが悪くなるのを防ぐことができる。 In addition, a plurality of cuts may be formed in the ring member at intervals in the circumferential direction.
In this case, when the cap main body is moved upward as described above, not only the connecting piece but also the ring member can be broken, and has the cap main body been removed from the inner plug? It can be shown more clearly to consumers. Further, since the ring member is broken when the unopened container with the cap is opened, the ring member can be easily removed from the cap body once opened in this way, and the ring member is provided. As a result, it is possible to prevent the convenience and appearance of the container with a cap from being deteriorated.

この発明に係るキャップ付き容器によれば、製造コストの増大を抑えつつ、キャップ本体が内栓から取り外されたことがあるか否かを需要者に示すことができる。   According to the cap-equipped container according to the present invention, it is possible to indicate to the consumer whether or not the cap body has been removed from the inner plug while suppressing an increase in manufacturing cost.

The peripheral surface is formed so as to continuously extend over the entire circumference. Furthermore, the upper end opening edge of the mouth portion 12 and the second cylindrical portion 18 are in contact with each other in a liquid-tight state. Further, the first and second cylindrical portions 17 and 18 are fixed to the mouth portion 12.

キャップ本体１６は、天板部２０と、天板部２０の裏面に垂設されて、前記第１筒部１７の内周面に嵌合された嵌合筒部２１と、天板部２０の裏面に垂設されて、嵌合筒部２１よりも大径で、かつ内周面に、前記第１筒部１７の雄ねじ部１７ａと螺合する雌ねじ部２２ａが形成された螺合筒部２２と、天板部２０の外周縁から垂設された周壁部２３とを備えている。そして、天板部２０において、第１筒部１７の内側と対向する部分に形成された貫通孔が前記注出口１３とされている。なお、周壁部２３の前記中心軸線Ｏ方向の下端部内周面は、第２筒部１８の前記中心軸線Ｏ方向の下端部外周面と容器本体１１の径方向で対向している。   The cap body 16 includes a top plate portion 20, a fitting tube portion 21 that is suspended from the back surface of the top plate portion 20 and is fitted to the inner peripheral surface of the first tube portion 17, and the top plate portion 20. A threaded tube portion 22 that is provided on the back surface and has a diameter larger than that of the fitting tube portion 21 and an inner peripheral surface formed with a female thread portion 22a that is threadedly engaged with the male thread portion 17a of the first tube portion 17. And a peripheral wall portion 23 that is suspended from the outer peripheral edge of the top plate portion 20. And in the top plate part 20, the through-hole formed in the part facing the inner side of the 1st cylinder part 17 is made into the said spout 13. The inner peripheral surface of the lower end portion of the peripheral wall portion 23 in the direction of the central axis O faces the outer peripheral surface of the lower end portion of the second tube portion 18 in the direction of the central axis O in the radial direction of the container body 11.

さらに、図示の例では、天板部２０の表面において注出口１３と同軸上に、注出筒部２４が立設されており、容器本体１１の内部から第１筒部１７の内側を通って注出口１３に到達した内容物は、この注出筒部２４の内側を通って外部に注出されるようになっている。そして、天板部２０には、注出筒部２４を含むその表面全体を開閉するように、ヒンジ部２０ａ回りに回動可能に支持された蓋部２６が設けられている。なお、蓋部２６の内面には栓２６ａが立設されており、この蓋２６を閉じたときに、栓２６ａが注出筒部２４の内周面に嵌められるようになっている。   Furthermore, in the example shown in the figure, a pouring tube portion 24 is erected on the surface of the top plate portion 20 coaxially with the pouring port 13 and passes from the inside of the container body 11 to the inside of the first tube portion 17. The contents that have reached the spout 13 are poured out through the inside of the pipe barrel 24. And the top part 20 is provided with the cover part 26 supported so that rotation around the hinge part 20a was possible so that the whole surface including the extraction | pouring cylinder part 24 could be opened and closed. A plug 26 a is erected on the inner surface of the lid portion 26, and when the lid 26 is closed, the plug 26 a is fitted on the inner peripheral surface of the dispensing cylinder portion 24.

そして、本実施形態では、キャップ本体１６の周壁部２３に係合し、かつ第２筒部１８の外周面に連結片２７を介して連結されたリング部材２８が備えられている。図示の例では、リング部材２８はその全周にわたって連続的に延在している。また、連結片２７は、リング部材２８の前記中心軸線Ｏ方向の下端部内周面と、第２筒部１８の前記中心軸線Ｏ方向の下端部外周面とを、周壁部２３の下端開口縁を跨いで連結し、前記中心軸線Ｏ回りに間隔をあけて複数設けられている。また、リング部材２８の前記中心軸線Ｏ方向の上端部内周面にその全周にわたって連続的に延在した第３係合凸部２８ａが突設され、周壁部２３の前記中心軸線Ｏ方向の下端部外周面にその全周にわたって連続的に延在した係合凹部２３ａが形成されている。   In the present embodiment, a ring member 28 that is engaged with the peripheral wall portion 23 of the cap body 16 and is connected to the outer peripheral surface of the second cylindrical portion 18 via a connecting piece 27 is provided. In the illustrated example, the ring member 28 extends continuously over the entire circumference. Further, the connecting piece 27 connects the inner peripheral surface of the lower end portion of the ring member 28 in the direction of the central axis O and the outer peripheral surface of the lower end portion of the second cylindrical portion 18 in the direction of the central axis O, and the lower end opening edge of the peripheral wall portion 23. A plurality are connected across the central axis O with a space therebetween. Further, a third engagement convex portion 28a that continuously extends over the entire circumference of the inner circumferential surface of the upper end portion of the ring member 28 in the central axis O direction protrudes, and the lower end of the peripheral wall portion 23 in the central axis O direction. An engaging recess 23a extending continuously over the entire circumference is formed on the outer peripheral surface of the part.

さらに、本実施形態では、リング部材２８には、図１に示されるように、その周方向に間隔をあけて複数の切込み２８ｂが形成されている。なお、図示の例では、切込み２８ｂは、前記中心軸線Ｏ方向の下方に向けて開口して形成されている。また、この切込み２８ｂは、リング部材２８の径方向に貫通して形成されている。さらに、連結片２７は、リング部材２８の内周面において、その周方向で隣合う切込み２８ｂ同士の間の中央部に設けられている。また、内栓１５、連結片２７およびリング部材２８は、キャップ本体１６を形成する材質よりも破断強度の低い材質で一体的に形成されている。   Furthermore, in this embodiment, as shown in FIG. 1, the ring member 28 is formed with a plurality of cuts 28b at intervals in the circumferential direction. In the illustrated example, the cut 28b is formed to open downward in the direction of the central axis O. Further, the cut 28b is formed so as to penetrate in the radial direction of the ring member 28. Furthermore, the connection piece 27 is provided in the center part between the notches 28b adjacent in the circumferential direction on the inner peripheral surface of the ring member 28. The inner plug 15, the connecting piece 27, and the ring member 28 are integrally formed of a material having a lower breaking strength than the material forming the cap body 16.

そして、以上のように構成されたキャップ付き容器１０では、未開封の状態でキャップ本体１６を前記中心軸線Ｏ回りに回動させ前記雄ねじ部１７ａに沿わせつつ前記中心軸線Ｏ方向の上方に移動させると、周壁部２３に係合されたリング部材２８も上方に移動させられることになるが、内栓１５はこの移動に追従せず口部１２に取り付けられた状態に維持される。したがって、このようにキャップ本体１６を内栓１５に対して上方に移動させると、リング部材２８と内栓１５とを連結する連結片２７には引張力が作用し、この引張力によって連結片２７が破断するようになっている。
一方、リング部材２８には、前述したキャップ本体１６の上方に向けた移動によって、切込み２８ｂの前記中心軸線Ｏ方向の切込み量が進展するような力が作用し、このリング部材２８が周方向で分割されるようになっている。 And in the container 10 with a cap comprised as mentioned above, the cap main body 16 is rotated around the said central axis O in the unopened state, and it moves to the said central axis O direction upward along the said external thread part 17a. As a result, the ring member 28 engaged with the peripheral wall portion 23 is also moved upward, but the inner plug 15 does not follow this movement and is kept attached to the mouth portion 12. Therefore, when the cap body 16 is moved upward with respect to the inner plug 15 in this way, a tensile force acts on the connecting piece 27 that connects the ring member 28 and the inner plug 15, and the connecting piece 27 is caused by this tensile force. Is designed to break.
On the other hand, a force is applied to the ring member 28 so that the cut amount of the cut 28b in the direction of the central axis O is developed by the upward movement of the cap body 16 described above. It is designed to be divided.

このように連結片２７を破断してキャップ本体１６を内栓１５から取り外し、第１筒部１７の内側を外部に開放した後に、プルリング１９ｂを前記中心軸線Ｏ方向の上方に引き上げてスコア１９ｃを破断させることにより、平板部１９ａを開口させて、第１筒部１７の内側と容器本体１１の内部とを連通させる。そして、キャップ本体１６を再度第１筒部１７に螺着した後、容器本体１１内の内容物を使用する際、蓋部２６を開いて注出筒部２４を開口させ、この内容物を、第１筒部１７の内側および注出口１３をこの順に通過させて注出筒部２４から外部に注出するようになっている。   In this way, after breaking the connecting piece 27 and removing the cap body 16 from the inner plug 15 and opening the inside of the first tube portion 17 to the outside, the pull ring 19b is pulled upward in the direction of the central axis O to obtain a score 19c. By breaking, the flat plate portion 19a is opened, and the inside of the first tube portion 17 and the inside of the container body 11 are communicated. Then, after screwing the cap body 16 to the first cylinder part 17 again, when using the contents in the container body 11, the lid part 26 is opened to open the dispensing cylinder part 24. The inside of the 1st cylinder part 17 and the spout 13 are passed in this order, and it pours out from the extraction cylinder part 24 outside.

以上説明したように本実施形態に係るキャップ付き容器１０によれば、キャップ本体１６が一度でも内栓１５から取り外されると、連結片２７が破断されることになるので、その後に、このキャップ本体１６を再度内栓１５に取り付けたとしても、少なくともリング部材２８を前記中心軸線Ｏ回りに回転自在とすることが可能になり、キャップ本体１６が内栓１５から取り外されたことがあるか否かを需要者に示すことができる。しかも、樹脂フィルムを用いないので、このキャップ付き容器１０の製造コストの増大を抑えることもできる。   As described above, according to the cap-equipped container 10 according to the present embodiment, when the cap body 16 is once removed from the inner plug 15, the connecting piece 27 is broken. Even if 16 is attached to the inner plug 15 again, at least the ring member 28 can be rotated around the central axis O, and whether the cap body 16 has been removed from the inner plug 15 or not. Can be shown to the consumer. And since the resin film is not used, the increase in the manufacturing cost of this container 10 with a cap can also be suppressed.

また、本実施形態では、内栓１５、連結片２７およびリング部材２８が、キャップ本体１６を形成する材質よりも破断強度の低い材質で一体的に形成されているので、周壁部２３にリング部材２８を係合した状態で、キャップ本体１６を内栓１５に対して上方に移動させたときに、連結片２７を容易に破断することが可能になる。しかも、内栓１５、連結片２７およびリング部材２８が一体的に形成されているので、これら１５、２７、２８を容易に形成することが可能になり、キャップ付き容器１０の製造コストの増大を確実に抑えることができる。   In the present embodiment, the inner plug 15, the connecting piece 27, and the ring member 28 are integrally formed of a material having a breaking strength lower than that of the material forming the cap body 16. When the cap body 16 is moved upward with respect to the inner plug 15 in a state where the 28 is engaged, the connecting piece 27 can be easily broken. In addition, since the inner plug 15, the connecting piece 27, and the ring member 28 are integrally formed, the 15, 27, and 28 can be easily formed, and the manufacturing cost of the capped container 10 is increased. It can be surely suppressed.

さらに、本実施形態では、リング部材２８に、その周方向に間隔をあけて複数の切込み２８ｂが形成されているので、前述のようにキャップ本体１６を上方に移動させたときに、連結片２７だけでなく、リング部材２８をも破断させることが可能になり、キャップ本体１６が内栓１５から取り外されたことがあるか否かを需要者に一層明確に示すことができる。
さらに、未開封のキャップ付き容器１０を開封する際にリング部材２８が破断されるので、このように一旦開封した後は、このリング部材２８をキャップ本体１６から容易に取り除くことが可能になり、リング部材２８を設けたことによりキャップ付き容器１０の使い勝手や見映えが悪くなるのを防ぐことができる。 Furthermore, in this embodiment, since the ring member 28 is formed with a plurality of cuts 28b at intervals in the circumferential direction, when the cap body 16 is moved upward as described above, the connecting piece 27 In addition, the ring member 28 can be broken, and it is possible to more clearly indicate to the consumer whether or not the cap body 16 has been removed from the inner plug 15.
Further, since the ring member 28 is broken when the unopened cap-equipped container 10 is opened, the ring member 28 can be easily removed from the cap body 16 after being opened in this manner. By providing the ring member 28, it is possible to prevent the usability and appearance of the capped container 10 from being deteriorated.

なお、本発明の技術的範囲は前記実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば、前記実施形態では、未開封状態からキャップ本体１６を取り外したときに、連結片２７およびリング部材２８の双方を破断させたが、連結片２７のみを破断させるようにしてもよい。
また、前記実施形態では、キャップ本体１６と内栓１５とを螺合させたが、例えば着脱可能にアンダーカット嵌合させてもよい。 The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, when the cap body 16 is removed from the unopened state, both the connecting piece 27 and the ring member 28 are broken, but only the connecting piece 27 may be broken.
Moreover, in the said embodiment, although the cap main body 16 and the inner stopper 15 were screwed together, you may carry out undercut fitting, for example so that attachment or detachment is possible.

さらに、キャップ本体１６の周壁部２３とリング部材２８とを係合する構成として、前記実施形態では、周壁部２３の前記中心軸線Ｏ方向の下端部外周面にその全周にわたって連続的に延在した係合凹部２３ａを形成したが、これに代えて、例えば、係合凹部２３ａを周方向に断続的に延在させるようにしてもよいし、あるいは、周壁部２３の前記下端部外周面にその全周にわたって連続的に延在した係合凸部を形成してもよいし、さらに、図３および図４に示されるように、係合凸部２９を周方向に断続的に延在させてもよい。   Furthermore, as a configuration in which the peripheral wall portion 23 of the cap body 16 and the ring member 28 are engaged, in the above-described embodiment, the peripheral wall portion 23 continuously extends over the entire circumference on the outer peripheral surface of the lower end portion in the central axis O direction. However, instead of this, for example, the engagement recess 23a may be intermittently extended in the circumferential direction, or alternatively, on the outer peripheral surface of the lower end portion of the peripheral wall portion 23. Engaging convex portions that continuously extend over the entire circumference may be formed, and furthermore, as shown in FIGS. 3 and 4, the engaging convex portions 29 are intermittently extended in the circumferential direction. May be.

また、前記実施形態では、第２筒部１８の内周面に第２係合凸部１８ａを形成するとともに、口部１２の外周面に第１係合凸部１２ａを形成したが、これらの第２係合凸部１８ａおよび第１係合凸部１２ａは形成しないで、第２筒部１８の内周面と口部１２の外周面とをこれらの間に液密性を持たせて嵌合するようにしてもよい。さらに、前記実施形態に代えて、周壁部２３の内周面とリング部材２８の外周面とを係合した状態で、キャップ本体１６を内栓１５に対して上方に移動させて、連結片２７を破断させるようにしてもよい。さらにまた、リング部材２８に切込み２８ｂは形成しなくてもよい。また、内栓１５、連結片２７、およびリング部材２８は、キャップ本体１６を形成する材質よりも破断強度の低い材質で必ずしも形成する必要はない。さらに、前記実施形態では、リング部材２８として、キャップ付き容器１０を開封する前ではその全周にわたって連続的に延在し、開封したときに周方向に分割される構成を示したが、これに代えて、例えば、キャップ付き容器１０を開封する前から、図１に示されるようにその周方向における一部が分割された構成を採用してもよい。   Moreover, in the said embodiment, while forming the 2nd engagement convex part 18a in the internal peripheral surface of the 2nd cylinder part 18, and forming the 1st engagement convex part 12a in the outer peripheral surface of the opening part 12, The second engaging convex portion 18a and the first engaging convex portion 12a are not formed, and the inner peripheral surface of the second cylindrical portion 18 and the outer peripheral surface of the mouth portion 12 are fitted with liquid-tightness therebetween. You may make it match. Further, instead of the above embodiment, the cap body 16 is moved upward with respect to the inner plug 15 in a state where the inner peripheral surface of the peripheral wall portion 23 and the outer peripheral surface of the ring member 28 are engaged, and the connecting piece 27 May be broken. Furthermore, the notch 28b may not be formed in the ring member 28. Further, the inner plug 15, the connecting piece 27, and the ring member 28 are not necessarily formed of a material having a breaking strength lower than that of the material forming the cap body 16. Furthermore, in the said embodiment, before opening the container 10 with a cap as the ring member 28, it extended continuously over the perimeter, and when opened, the structure divided | segmented into the circumferential direction was shown. Instead, for example, a configuration in which a part in the circumferential direction is divided as shown in FIG. 1 before opening the capped container 10 may be adopted.

製造コストの増大を抑えつつ、キャップ本体が内栓から取り外されたことがあるか否かを需要者に示すことができる。   It is possible to indicate to the consumer whether or not the cap body has been removed from the inner plug while suppressing an increase in manufacturing cost.
