特開２０１０−７６８３９号公報JP-A-2010-76839

しかしながら、前記従来の吐出容器では、吐出容器を持つ手の体温及び外気温等により、内容器内の温度が変動し、内容器の内圧が変動する恐れがあった。この場合、例えば、内容器の内圧が上昇していると、内容物を吐出するときに、内容器内の圧力により内容物が吐出孔から意図せずに噴出する恐れがある。 However, in the conventional discharge container, the temperature inside the inner container may fluctuate due to the body temperature of the hand holding the discharge container, the outside air temperature, and the like, and the internal pressure of the inner container may fluctuate. In this case, for example, if the internal pressure of the inner container is rising, when the contents are discharged, the contents may be unintentionally ejected from the discharge hole due to the pressure inside the inner container.

本発明は、このような問題点に鑑みてなされたものであって、内容器内の温度の変動を抑えることができる吐出容器を提供することを目的とする。 The present invention has been made in view of such problems, and an object of the present invention is to provide a discharge container capable of suppressing fluctuations in temperature inside the inner container.

上記課題を解決するために、この発明は以下の手段を提案している。
本発明の吐出容器は、内容物が収容される容器本体と、前記容器本体内に連通する吐出孔が形成された吐出栓と、を備える吐出容器であって、前記容器本体は、前記内容物が収容される内容器と、前記内容器が内部に収容されるとともに可撓性に富む外容器と、を有し、前記内容器の胴部には、前記外容器の内周面との間に密封空間を画成する断熱凹部が形成され、前記外容器には、前記断熱凹部に流体を供給する流体導入孔が形成され、前記外容器には、前記流体導入孔を閉塞する閉塞部材が外嵌されていることを特徴としている。 In order to solve the above problems, the present invention proposes the following means.
The discharge container of the present invention is a discharge container including a container body in which the contents are housed and a discharge plug having a discharge hole formed in the container body, and the container body is the contents. It has an inner container in which the inner container is housed and an outer container in which the inner container is housed and is highly flexible, and the body of the inner container is between the inner peripheral surface of the outer container. A heat insulating recess that defines a sealed space is formed in the outer container, a fluid introduction hole for supplying fluid to the heat insulating recess is formed in the outer container, and a closing member for closing the fluid introduction hole is formed in the outer container. It is characterized by being externally fitted.

この場合、内容器の胴部の外周面と外容器の内周面との間に密封空間が配設されているので、この密封空間が吐出容器の外部と内容器内との間の断熱層として機能することとなり、例えば、吐出容器の外部から伝達される体温及び外気温等により、内容器内の温度が変動するのを抑制することができる。これにより、内容物を吐出する際に、内容物が吐出孔から意図せず噴出するのを抑えること等ができる。 In this case, since a sealing space is provided between the outer peripheral surface of the body of the inner container and the inner peripheral surface of the outer container, this sealing space is a heat insulating layer between the outside of the discharge container and the inside of the inner container. For example, it is possible to suppress fluctuations in the temperature inside the inner container due to the body temperature and the outside air temperature transmitted from the outside of the discharge container. As a result, when the contents are discharged, it is possible to prevent the contents from being unintentionally ejected from the discharge holes.

また、上記の吐出容器において、前記流体導入孔及び前記断熱凹部それぞれの容器軸周りに沿う周方向の位置が、互いに同等であってもよい。
この場合、流体導入孔から内容器の外周面と外容器の内周面との間に供給された流体を、周方向に迂回させずに短い移動距離で断熱凹部に至らせることができる。 Further, in the above discharge container, the positions of the fluid introduction hole and the heat insulating recess in the circumferential direction along the container axis may be the same as each other.
In this case, the fluid supplied from the fluid introduction hole between the outer peripheral surface of the inner container and the inner peripheral surface of the outer container can reach the heat insulating recess in a short moving distance without diverting in the circumferential direction.

また、上記の吐出容器において、前記断熱凹部は、前記内容器の胴部に、容器軸周りに沿う周方向に間隔をあけて複数形成され、前記内容器の胴部において、前記周方向で互いに隣り合う前記断熱凹部同士の間に位置して、前記外容器の内周面を支持する複数の支持部のうち、１つの前記支持部が前記外容器の内周面に固着され、残りの前記支持部は前記外容器の内周面に剥離可能に当接してもよい。
この場合、流体導入孔から流体を、内容器の外周面と外容器の内周面との間に供給すると、この流体が複数の断熱凹部のうちの１つに限らず、この断熱凹部に周方向で隣り合う他の断熱凹部にも、前記残りの支持部と外容器の内周面との間を通過して流入する。したがって、例えば外容器に複数の流体導入孔を形成し、これらの流体導入孔から複数の断熱凹部に各別に流体を供給する操作を採用する必要がなく、この吐出容器を容易に製造することができる。 Further, in the discharge container, a plurality of the heat insulating recesses are formed in the body of the inner container at intervals in the circumferential direction along the circumference of the container axis, and in the body of the inner container, each other in the circumferential direction. Of the plurality of support portions that are located between the adjacent heat insulating recesses and support the inner peripheral surface of the outer container, one said support portion is fixed to the inner peripheral surface of the outer container, and the remaining said. The support portion may be detachably contacted with the inner peripheral surface of the outer container.
In this case, when the fluid is supplied from the fluid introduction hole between the outer peripheral surface of the inner container and the inner peripheral surface of the outer container, the fluid is not limited to one of the plurality of heat insulating recesses, but is peripheral to the heat insulating recess. It also flows into other heat insulating recesses adjacent to each other in the direction, passing between the remaining support portion and the inner peripheral surface of the outer container. Therefore, for example, it is not necessary to form a plurality of fluid introduction holes in the outer container and separately supply the fluid from these fluid introduction holes to the plurality of heat insulating recesses, and this discharge container can be easily manufactured. it can.

また、上記の吐出容器において、前記容器本体は、胴部と、前記胴部より小径の口部と、を有するとともに、これらの胴部及び口部が容器軸方向に連設されてなり、前記流体導入孔は、前記外容器の口部に形成され、前記断熱凹部は、前記内容器の胴部における容器軸方向の全長にわたって形成され、前記内容器の胴部を容器軸方向に沿う前記口部側に向けて開口してもよい。
この場合、流体導入孔から内容器の外周面と外容器の内周面との間を胴部側に向けて流れる流体を、断熱凹部内に、その容器軸方向に沿う口部側に向けて開口する開口部を通して流入させることが可能になり、流体を断熱凹部内に容易に供給することができる。 Further, in the above-mentioned discharge container, the container body has a body portion and a mouth portion having a diameter smaller than that of the body portion, and these body portions and mouth portions are continuously provided in the container axial direction. The fluid introduction hole is formed in the mouth portion of the outer container, the heat insulating recess is formed over the entire length of the body portion of the inner container in the container axial direction, and the body portion of the inner container is formed in the mouth portion along the container axial direction. It may be opened toward the portion side.
In this case, the fluid flowing from the fluid introduction hole between the outer peripheral surface of the inner container and the inner peripheral surface of the outer container toward the body is directed into the heat insulating recess toward the mouth side along the axial direction of the container. It is possible to flow through the opening, and the fluid can be easily supplied into the heat insulating recess.

また、上記の吐出容器において、前記容器本体は、胴部と、前記胴部より小径の口部と、を有するとともに、これらの胴部及び口部が容器軸方向に連設されてなり、前記流体導入孔は、前記外容器の口部に形成され、前記容器本体の口部には、キャップが着脱自在に螺着される雄ねじ部が形成され、この雄ねじ部の容器軸周りに螺線状に延びるねじ山に、前記ねじ山の、容器軸周りに周回する周方向の延在を分断する間欠部が形成され、前記流体導入孔及び前記間欠部それぞれの前記周方向の位置が、互いに同等であってもよい。
この場合、流体導入孔から内容器の外周面と外容器の内周面との間を胴部側に向けて流れる流体が、雄ねじ部に到達したときに、間欠部を容器軸方向に通過させることが可能になり、雄ねじ部のねじ山によって流体の流動が阻害されてしまうのを抑制することができる。 Further, in the above-mentioned discharge container, the container body has a body portion and a mouth portion having a diameter smaller than that of the body portion, and these body portions and mouth portions are continuously provided in the container axial direction. The fluid introduction hole is formed in the mouth of the outer container, and a male screw portion to which the cap is detachably screwed is formed in the mouth of the container body, and a thread shape is formed around the container shaft of the male screw portion. An intermittent portion of the screw thread extending in the circumferential direction is formed on the thread extending to the above, and the positions of the fluid introduction hole and the intermittent portion in the circumferential direction are equivalent to each other. It may be.
In this case, when the fluid flowing from the fluid introduction hole between the outer peripheral surface of the inner container and the inner peripheral surface of the outer container toward the body side reaches the male threaded portion, the intermittent portion is passed in the container axial direction. This makes it possible to prevent the flow of the fluid from being obstructed by the thread of the male threaded portion.

また、上記の吐出容器において、前記吐出栓は、前記吐出孔に出没可能に挿通された塗布体を備えてもよい。
この場合、吐出孔を下方に向けた状態で、塗布体を被塗布部に押し当てて吐出孔内に塗布体を没入させると、吐出孔から内容物が吐出され被塗布部に内容物を塗布することができる。 Further, in the above-mentioned discharge container, the discharge plug may include a coating body that is inserted into the discharge hole so as to appear and disappear.
In this case, when the coated body is pressed against the portion to be coated to immerse the coated body in the discharge hole with the discharge hole facing downward, the content is discharged from the discharge hole and the content is coated on the portion to be coated. can do.

次に、以上のように構成された吐出容器１の製造方法について、断熱凹部２３と外容器１３の内周面との間に密封空間Ｓを画成する工程に重点をおいて説明する。
図３に示す容器本体１１は、例えば押出ブロー成形後に、各断熱凹部２３と外容器１３の内周面との間に密封空間Ｓが画成される前の状態である。流体導入孔１９を、公知のパンチ処理等により形成する。
流体導入孔１９から、内容器１２の外周面と外容器１３の内周面との間に流体を供給する。この流体は、外容器１３を膨張変形させつつ流体導入孔１９から下側に向けて流れ、まず雄ねじ部２１に到達したときに、対応間欠部２１ｂＡを下側に向けて通過する。そして、対応間欠部２１ｂＡを通過した流体は、対応断熱凹部２３Ａの上端開口部２３ａを通して対応断熱凹部２３Ａ内に供給される。 Next, the manufacturing method of the discharge container 1 configured as described above will be described with an emphasis on the step of defining the sealed space S between the heat insulating recess 23 and the inner peripheral surface of the outer container 13.
The container body 11 shown in FIG. 3 is, for example, in a state after extrusion blow molding and before a sealing space S is defined between each heat insulating recess 23 and the inner peripheral surface of the outer container 13. The fluid introduction hole 19 is formed by a known punching process or the like.
A fluid is supplied from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13. This fluid flows downward from the fluid introduction hole 19 while expanding and deforming the outer container 13, and when it first reaches the male screw portion 21, it passes through the corresponding intermittent portion 21bA downward. Then, the fluid that has passed through the corresponding intermittent portion 21bA is supplied into the corresponding heat insulating recess 23A through the upper end opening 23a of the corresponding heat insulating recess 23A.

対応断熱凹部２３Ａ内に供給された流体は、図４に示すように、対応断熱凹部２３Ａに周方向で隣り合う他の断熱凹部２３Ｂにも、他の支持部２４Ｂと外容器１３の内周面との間を通過して流入する。図示の例では、対応断熱凹部２３Ａに周方向の一方で隣り合う固着支持部２４Ａは外容器１３の内周面と固着されている。このため、対応断熱凹部２３Ａ内に供給された流体は、対応断熱凹部２３Ａに周方向の他方で隣り合う他の支持部２４Ｂと外容器１３の内周面との間を通過して、他の断熱凹部２３Ｂ内に流入する。
こうして各断熱凹部２３内に流体を供給して密封空間Ｓを画成した後で、外容器１３に閉塞部材５１を外嵌して、流体導入孔１９を閉塞する。
ここで、密封空間Ｓを画成した後、外容器１３の口部１５に閉塞部材５１を外嵌する前に外容器１３が復元変形することで、各断熱凹部２３内の流体が流体導入孔１９から排出されるのを抑制することができる。 As shown in FIG. 4, the fluid supplied into the corresponding heat insulating recess 23A also includes the other supporting portion 24B and the inner peripheral surface of the outer container 13 in the other heat insulating recess 23B adjacent to the corresponding heat insulating recess 23A in the circumferential direction. It passes between and flows in. In the illustrated example, the fixing support portion 24A adjacent to the corresponding heat insulating recess 23A in the circumferential direction is fixed to the inner peripheral surface of the outer container 13. Therefore, the fluid supplied into the corresponding heat insulating recess 23A passes between the other supporting portion 24B adjacent to the corresponding heat insulating recess 23A on the other side in the circumferential direction and the inner peripheral surface of the outer container 13, and other It flows into the heat insulating recess 23B.
After the fluid is supplied into each of the heat insulating recesses 23 to define the sealed space S, the closing member 51 is fitted into the outer container 13 to close the fluid introduction hole 19.
Here, after the sealed space S is defined, the outer container 13 is restored and deformed before the closing member 51 is externally fitted to the mouth portion 15 of the outer container 13, so that the fluid in each heat insulating recess 23 becomes a fluid introduction hole. It is possible to suppress the discharge from 19.

以上の吐出容器１は、内容器１２の胴部１６の外周面と外容器１３の内周面との間に密封空間Ｓが、吐出容器１の外部と内容器１２内との間の断熱層として機能する。
吐出容器１を使用するときには、例えば使用者は、吐出孔３７ａを下方に向けた状態で吐出容器１の胴部１６を手で持ち、塗布体３３を被塗布部に押し当てる。付勢部材４４の付勢力に抗して、吐出孔３７ａ内に塗布体３３の先端部３９を没入させると、吐出孔３７ａから内容物が吐出され被塗布部に塗布される。このとき、密封空間Ｓが断熱層となるため、吐出容器１の外部から伝達される体温及び外気温等により内容器１２内の温度が変動するのを抑制することができる。 In the above discharge container 1, a sealing space S is provided between the outer peripheral surface of the body 16 of the inner container 12 and the inner peripheral surface of the outer container 13, and a heat insulating layer between the outside of the discharge container 1 and the inside of the inner container 12. Functions as.
When using the discharge container 1, for example, the user holds the body portion 16 of the discharge container 1 by hand with the discharge hole 37a facing downward, and presses the coated body 33 against the coated portion. When the tip 39 of the coating body 33 is immersed in the discharge hole 37a against the urging force of the urging member 44, the contents are discharged from the discharge hole 37a and applied to the coated portion. At this time, since the sealed space S serves as a heat insulating layer, it is possible to suppress fluctuations in the temperature inside the inner container 12 due to the body temperature and the outside air temperature transmitted from the outside of the discharge container 1.

以上説明したように、本実施形態の吐出容器１によれば、内容器１２の胴部１６の外周面と外容器１３の内周面との間に密封空間Ｓが配設されているので、この密封空間Ｓが吐出容器１の外部と内容器１２内との間の断熱層として機能する。したがって、例えば、吐出容器１の外部から伝達される体温及び外気温等により、内容器１２内の温度が変動するのを抑制することができる。これにより、例えば被塗布部に内容物を塗布する際に、内容物が吐出孔３７ａから意図せず噴出したり、容器本体１１の胴部１６の外径が変化したりするのを抑えること等ができる。 As described above, according to the discharge container 1 of the present embodiment, the sealing space S is arranged between the outer peripheral surface of the body portion 16 of the inner container 12 and the inner peripheral surface of the outer container 13. The sealed space S functions as a heat insulating layer between the outside of the discharge container 1 and the inside of the inner container 12. Therefore, for example, it is possible to suppress fluctuations in the temperature inside the inner container 12 due to the body temperature and the outside air temperature transmitted from the outside of the discharge container 1. As a result, for example, when the content is applied to the portion to be coated, it is possible to prevent the content from being unintentionally ejected from the discharge hole 37a or the outer diameter of the body portion 16 of the container body 11 from changing. Can be done.

流体導入孔１９及び対応断熱凹部２３Ａそれぞれの周方向の位置が、互いに同等である。このため、流体導入孔１９から内容器１２の外周面と外容器１３の内周面との間に供給された空気を、周方向に迂回させずに短い移動距離で対応断熱凹部２３Ａに至らせることができる。
複数の支持部２４のうち、固着支持部２４Ａが外容器１３の内周面に固着され、残りの他の支持部２４Ｂは外容器１３の内周面に剥離可能に当接している。流体導入孔１９から流体を、内容器１２の外周面と外容器１３の内周面との間に供給すると、この流体が複数の断熱凹部２３のうちの１つの対応断熱凹部２３Ａに限らず、この対応断熱凹部２３Ａに周方向で隣り合う他の断熱凹部２３Ｂにも、他の支持部２４Ｂと外容器１３の内周面との間を通過して流入する。したがって、例えば外容器１３に複数の流体導入孔１９を形成し、これらの流体導入孔１９から複数の断熱凹部２３に各別に流体を供給する操作を採用する必要がなく、この吐出容器１を容易に製造することができる。 The positions of the fluid introduction hole 19 and the corresponding heat insulating recess 23A in the circumferential direction are the same as each other. Therefore, the air supplied from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13 is brought to the corresponding heat insulating recess 23A in a short moving distance without diverting in the circumferential direction. be able to.
Of the plurality of support portions 24, the fixed support portion 24A is fixed to the inner peripheral surface of the outer container 13, and the remaining other support portions 24B are in detachable contact with the inner peripheral surface of the outer container 13. When a fluid is supplied from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13, this fluid is not limited to the corresponding heat insulating recess 23A of one of the plurality of heat insulating recesses 23. It also flows into the other heat insulating recess 23B adjacent to the corresponding heat insulating recess 23A in the circumferential direction by passing between the other support portion 24B and the inner peripheral surface of the outer container 13. Therefore, for example, it is not necessary to form a plurality of fluid introduction holes 19 in the outer container 13 and separately supply the fluid from these fluid introduction holes 19 to the plurality of heat insulating recesses 23, and the discharge container 1 can be easily operated. Can be manufactured in.

対応断熱凹部２３Ａは、容器軸Ｏ方向に沿う口部１５側に向けて開口している。これにより、流体導入孔１９から内容器１２の外周面と外容器１３の内周面との間を胴部１６側に向けて流れる流体を、対応断熱凹部２３Ａ内に上端開口部２３ａを通して流入させることが可能になり、流体を対応断熱凹部２３Ａ内に容易に供給することができる。
流体導入孔１９、及び雄ねじ部２１の対応間欠部２１ｂＡそれぞれの周方向の位置が、互いに同等である。したがって、流体導入孔１９から内容器１２の外周面と外容器１３の内周面との間を胴部１６側に向けて流れる流体が、雄ねじ部２１に到達したときに、対応間欠部２１ｂＡを容器軸Ｏ方向に通過させることが可能になる。雄ねじ部２１のねじ山２１ａによって流体の流動が阻害されてしまうのを、抑制することができる。 The corresponding heat insulating recess 23A is open toward the mouth portion 15 side along the container axis O direction. As a result, the fluid flowing from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13 toward the body portion 16 side flows into the corresponding heat insulating recess 23A through the upper end opening 23a. This makes it possible to easily supply the fluid into the corresponding heat insulating recess 23A.
The positions of the fluid introduction hole 19 and the corresponding intermittent portion 21bA of the male screw portion 21 in the circumferential direction are the same as each other. Therefore, when the fluid flowing from the fluid introduction hole 19 toward the body portion 16 side between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13 reaches the male thread portion 21, the corresponding intermittent portion 21bA is provided. It becomes possible to pass in the container axis O direction. It is possible to prevent the flow of the fluid from being obstructed by the thread 21a of the male thread portion 21.

吐出栓３１が、塗布体３３を備える。このため、吐出孔３７ａを下方に向けた状態で、塗布体３３を被塗布部に押し当てて吐出孔３７ａ内に塗布体３３を没入させると、吐出孔３７ａから内容物が吐出され被塗布部に内容物を塗布することができる。 The discharge plug 31 includes a coating body 33. Therefore, when the coating body 33 is pressed against the coated portion to immerse the coating body 33 in the discharge hole 37a with the discharge hole 37a facing downward, the contents are discharged from the discharge hole 37a and the coated portion is coated. The contents can be applied to.

なお、本実施形態では、図５に示す吐出容器２のように、雄ねじ部５６が、容器本体１１の口部１５でなく、閉塞部材５１の外周面に形成されてもよい。この場合、雄ねじ部５６に間欠部は形成されなくてもよい。
図６に示す吐出容器３のように、複数の支持部２４の全てが外容器１３の内周面に固着される固着支持部２４Ａであってもよい。図示の例では、内容器１２の胴部１６に４つの固着支持部２４Ａが形成されている。
この場合、吐出容器３の製造時に、周方向で隣り合う断熱凹部２３間の固着支持部２４Ａを通過して流体が流入しない。このため、外容器１３には、各断熱凹部２３に対応して複数の流体導入孔１９を各別に形成する。このように、吐出容器が有する、外容器１３の内周面に固着される固着支持部２４Ａの数は、特に限定されない。 In the present embodiment, as in the discharge container 2 shown in FIG. 5, the male screw portion 56 may be formed on the outer peripheral surface of the closing member 51 instead of the mouth portion 15 of the container body 11. In this case, the male screw portion 56 does not have to have an intermittent portion.
As in the discharge container 3 shown in FIG. 6, all of the plurality of support portions 24 may be fixed support portions 24A fixed to the inner peripheral surface of the outer container 13. In the illustrated example, four fixing support portions 24A are formed on the body portion 16 of the inner container 12.
In this case, when the discharge container 3 is manufactured, the fluid does not flow in through the fixing support portion 24A between the heat insulating recesses 23 adjacent to each other in the circumferential direction. Therefore, a plurality of fluid introduction holes 19 are separately formed in the outer container 13 corresponding to the heat insulating recesses 23. As described above, the number of the fixing support portions 24A fixed to the inner peripheral surface of the outer container 13 of the discharge container is not particularly limited.

流体導入孔１９及び断熱凹部２３それぞれの周方向の位置がずれていてもよい。流体導入孔１９及び間欠部２１ｂそれぞれの周方向の位置がずれていてもよい。断熱凹部２３に上端開口部２３ａは形成されなくてもよい。これらのように構成しても、吐出容器に密封空間Ｓを画成する断熱凹部２３が形成されていることで、内容器１２内の温度の変動を抑えることができるからである。
流体導入孔１９は、外容器１３の口部１５に形成されているとした。しかし、流体導入孔１９が形成される外容器１３の部位はこれに限定されず、流体導入孔１９は外容器１３の胴部１６及び底部１７に形成されてもよい。 The positions of the fluid introduction hole 19 and the heat insulating recess 23 in the circumferential direction may be deviated from each other. The positions of the fluid introduction hole 19 and the intermittent portion 21b in the circumferential direction may be deviated. The upper end opening 23a may not be formed in the heat insulating recess 23. Even with these configurations, the temperature fluctuation inside the inner container 12 can be suppressed by forming the heat insulating recess 23 that defines the sealed space S in the discharge container.
It is assumed that the fluid introduction hole 19 is formed in the mouth portion 15 of the outer container 13. However, the portion of the outer container 13 in which the fluid introduction hole 19 is formed is not limited to this, and the fluid introduction hole 19 may be formed in the body portion 16 and the bottom portion 17 of the outer container 13.

雄ねじ部２１のねじ山２１ａに形成される間欠部２１ｂの数は１つでもよいし、ねじ山２１ａに間欠部２１ｂが形成されなくてもよい。容器本体１１とキャップ６１とが螺着により接続されず、例えばアンダーカット嵌合等により接続されてもよい。
実施形態では流体は空気であるとしたが、流体はこれに限定されず、ヘリウムガス等の気体でもよいし、水等の流体でもよい。
内容物は、粉状、粒状、錠剤状等の固体のものや、液体のものであってもよい。内容物として、揮発性の高い液体を用いることも可能である。
吐出栓３１として、塗布体３３を有しない構成を採用してもよい。 The number of intermittent portions 21b formed on the thread 21a of the male thread portion 21 may be one, or the intermittent portion 21b may not be formed on the thread 21a. The container body 11 and the cap 61 may not be connected by screwing, but may be connected by, for example, undercut fitting.
In the embodiment, the fluid is air, but the fluid is not limited to this, and may be a gas such as helium gas or a fluid such as water.
The content may be a solid such as powder, granular or tablet, or a liquid. It is also possible to use a highly volatile liquid as the content.
As the discharge plug 31, a configuration that does not have the coating body 33 may be adopted.
