Description

【0001】
【産業上の利用分野】
本発明は二重エヤゾール装置の製造法に関する。さらに詳しくは、内袋やピストンなどの隔壁に洩れがないことを確認しながら内容物を充填することができる二重エヤゾール装置の製造法に関する。
【0002】
【従来の技術】
従来、アルミ箔や積層フィルムなどからなる内袋を耐圧容器の開口部に取りつけて容器内を区切り、内袋内に噴射させるべき原液を入れると共に、容器と内袋との間に加圧剤(噴射剤、プロペラント)を充填した二重エヤゾール装置が用いられている。このような二重エヤゾール装置は、原液とそれを押し出すための加圧剤、たとえばLPGなどの液化ガス、あるいは炭酸ガスや窒素ガスなどの圧縮ガスとを分離して別々の部屋に充填する必要がある場合、たとえば両者を混ぜると反応する場合や、原液が食品である場合などに用いられる。また内袋に代えて、容器内を摺動するピストンによって区切ったものも知られている。
【0003】
上記内袋やピストンは、原液と加圧剤とを仕切る隔壁であるので、そのシール性能が重要であり、とくにピンホールやひび割れなどの穴あきがあれば液化ガスや圧縮ガスが原液に混入することになる。このようなピンホールやひび割れなどを防ぐ方法は各種提案されているが、いずれも完全なものではない。そのためたとえば1個ずつ水に漬けるなどにより検品し、洩れがないものだけを用いて組み立てるようにしている。しかしそのような1個ずつの検査はきわめて煩雑であり、しかもピストンと容器との摺動面における洩れなど、組み立て後に初めて生ずる洩れは発見できない。
【0004】
なお従来の二重エヤゾール装置の通常の組み立て方法は、▲1▼まず内袋を容器に仮着し、あるいはピストンを挿入したうえで、内袋内またはピストン上部の原液室に原液を充填し、▲2▼容器口部に原液用バルブを取りつけ(同時に内袋を固定し)、▲3▼加圧剤充填バルブから加圧剤を充填する、といった方法がとられている。なお内袋を原液用バルブで固定する前に、内袋と容器の隙間から高圧で加圧剤を充填するいわゆるアンダーカップ充填も行われている。
【0005】
【発明が解決しようとする課題】
本発明は従来の内袋やピストンなどの隔壁を1個ずつあらかじめ検査する工程を省き、二重エヤゾール製品の生産工程の合理化を企ることを技術課題とするものである。
【0006】
【課題を解決するための手段】
本発明の二重エヤゾール装置の製造方法は、(a)耐圧性の容器に圧力伝達可能な隔壁および原液用バルブを取りつけ、(b)加圧剤充填バルブから加圧剤を充填し、(c)前記原液用バルブを開放して原液室を空にし、(d)ついで原液室を塞いでその内圧を測定し、(e)原液室の内圧が所定圧より低いことにより隔壁の洩れがないことを確認したうえで、原液用バルブから原液を充填することを特徴としている。
【0007】
上記製造方法において、前記圧力伝達可能な隔壁は可逆的に膨縮変形する内袋とすることができ、その場合は、内袋を原液用バルブと共に容器の開口部から挿入して固定する。また前記圧力伝達可能な隔壁は、容器内で移動自在のピストンとすることができ、その場合は、ピストンを容器の底部開口から挿入した後に、底部開口を底板により閉じる。
【0008】
【作用】
噴射剤を噴射剤室に充填すると、その圧力を受けて隔壁が変形ないし移動し、原液室が収縮する。その状態で原液用バルブを開放すると、原液室の内圧が大気圧まで下がる。ついで原液用バルブを圧力計で塞ぐと、隔壁にピンホールやひび割れなどの欠陥がある場合には、原液室に加圧剤が進入してきて、ある程度の内圧を生ずることになる。したがってその状態で内圧を測定し、その内圧が所定の圧力より低い場合は欠陥がないことが確認でき、所定の圧力より高い場合は洩れがあることがわかる。
【0009】
【実施例】
つぎに図面を参照しながら本発明の二重エヤゾール装置の製造法の実施例を説明する。図1は本発明の製造法の一実施例を示す工程図、図2および図3はそれぞれ図1の製造法により得られる二重エヤゾール装置の一例を示す一部切り欠き斜視図および断面図、図4は本発明にかかわるチューブの一実施例を示す要部断面図、図5は本発明の製造法の他の実施例を示す工程図、図6は図5の製造法により得られる二重エヤゾール装置の一例を示す断面図である。
【0010】
図1は内袋を隔壁として用いる二重エヤゾール装置の製造工程の概略を示しており、左よりバルブ・隔壁取りつけ工程S1、加圧剤充填工程S2、原液室開放・内圧測定工程S3、S4、原液充填工程S5の順に進められる。前記バルブ・内袋取りつけ工程S1は図2に示すように、耐圧容器1の上端開口部2から、バルブ3と内袋4とが一体になったものを挿入し、開口部2にバルブ3のマウンティングカップ3aをクリンプすることにより、両者を容器1に固定する工程である。容器1は耐圧性のアルミニウム缶、ブリキ缶、ガラスびんなどの従来公知のものである。またバルブ3はその中心に挿入したステムを押したり傾けたりすることにより、内外を連通させうる公知のものである。内袋4はアルミ箔と合成樹脂フィルムとの積層シートなどを2枚重ねて周囲を接着ないし熱融着したものであり、バルブ3の下端のチューブ5を挟んで密閉した袋状に構成されている。そしてそのチューブ5を介してバルブ3と内袋4とは一体にされており、内袋4は図2に示すように縦方向に細長く折りたたんだ状態で開口部2から挿入され、容器1の内部ではいくらか拡がる。
【0011】
容器1の底板6には、従来公知の加圧剤充填バルブ7が設けられている。加圧剤充填バルブ7は、たとえば原液用のバルブ3のバルブマウンティングカップ3aの底部に形成した貫通孔と、その下側面に密接されるガスケットとから構成することもできる。バルブ3および内袋4を容器1に挿入して固定した後、原液を入れずに、まず前記加圧剤充填バルブ7から、液化ガスあるいは圧縮ガスなどの加圧剤Pが充填される(工程S2)。なお図1では液化ガスの場合を示しており、その液化ガスPは液相P1と気相P2とに分かれて、気相P2の部分が内袋4を周囲から圧縮することになる。
【0012】
ついで工程S3、S4に示すように、バルブ3に開放と閉鎖を選択できる切り換えバルブ8ないし栓を介して圧力計PGを取りつける。なお圧力計PGは圧力センサなどであってもよい。そしてまず切り換えバルブ8を開放側に切り換えた状態で原液用バルブ3のステムを押し、内袋4内をノズル9を通じて0気と連通させ、加圧剤P2の圧力により内袋4を空にする(工程S3)。さらにその状態で切り換えバルブ8を切り換えてノズル9を閉じ、内袋4の内圧を圧力計PGで測定する(工程S4)。
【0013】
このとき内袋4にピンホールやひび割れがないのであれば、内袋4内は圧力O(大気圧)のままであるが、ピンホールなどがあれば加圧剤P2内袋4内に入つてくるので、0.1 〜5kg/cm G程度の圧力が生ずる。したがって上記圧力が検出されたときは原液を充填することなく、内袋4を交換する部署などに戻し、圧力が検出されないときは、原液Mを加圧下に充填する工程S4に移行させる。そしてその工程S5で原液Mを充填することにより、さらに図3に示すようなステム13や押しボタン11などを取りつけることにより、二重エヤゾール装置Aが完成する。なお図4に示すように、前記原液用バルブ3の下端のチューブ5を内袋4の下端近辺まで延設しておき、そのチューブ5の側壁に貫通孔5aを形成したり、多孔性材料によりチューブ5を形成しておくと、内袋4が加圧剤の圧力で密着状態になっても通気路が確保され、圧力差を明敏に検出することができる。そのためピンホールなどの有無を正確に検出しうる。
【0014】
上記のごとく本発明の製造法においては、加圧剤P2、原液Mの順に充填していき、その途中で加圧剤P2の圧力により内袋4のピンホールなどの有無を検出するので、あらかじめ内袋4を1個ずつ検査しておく必要がなく、しかも0.1 〜5kg/cm Gという大きい圧力差で検出することができる。上記工程S1〜S5は通常の充填工程のごとくインデックステーブル式のターンテーブルで送りながら充填する従来の充填装置により順に行なっていくことができる。しかし他の装置たとえばロータリ式を用いて行なうこともできる。
【0015】
前記図1〜2の実施例では、内袋4をバルブ3に一体に取りつけているが、図3に示すように、内袋4の上端開口部を容器1の開口部2のビード2a上に、バルブ3のマウンティングカップ3aと一体にクリンプするようにしてもよい。このものにおいても、初めに加圧剤充填バルブ7から加圧剤を入れ、ついで内袋4内を空にし、さらにその内圧を測定し、最後に内袋4に原液をPを充填する工程は同じである。なお図3の12は押しボタン11に設けたノズル、13はステム、14はステム復帰用のバネ、15はステムおよびバネ14を収容し、マウティングカップにとりつけられるバルブハウジングである。
【0016】
図5は隔壁として耐圧性の容器1の内部を縦方向にスライド移動自在のピストン21を有する二重エヤゾール装置の製造法を示している。この製造法はバルブ3およびピストン(隔壁)21を取りつける工程S1、加圧剤Pを充填する工程S2、原液室を開放するS3、内圧を測定する工程S4および原液Mを充填する工程S5を有し、原液室開放工程S3と内圧測定工程S4とが別個にされている以外は実質的に図1の製造法と同じである。なおピストン21は容器1の下部から挿入するので、底板6はその後に取りつける(工程S1)。またバルブ3の取りつけとピストン21の挿入はいずれを先にしても同じである。加圧剤充填工程S2においては、加圧剤P2は底板6に設けた加圧剤充填バルブ7から充填するが、そのときピストン21が原液室22内の空気を圧縮しながら上昇し、釣り合った位置で停止しする(工程S2の想像線参照)。そしてバルブ3のステム23を操作して原液室22を開放することにより、原液室22内の空気が放出され、大気圧と同じ圧力になる(工程S3)。さらにバルブ3のステム23に圧力計PGを取りつけてステム23の開口を塞ぐと共に、内圧を測定する(工程S4)。そのときピストン21にひび割れがあったり、ピストン21と容器1の摺動部に隙間があったりすると、原液室22内に加圧剤が洩れて侵入してくる。そのため原液室22の内圧を圧力計PGで測定することにより、洩れの有無を検出することができる(工程S4)。洩れがないことが確認できたときは、バルブ3から原液室22内に加圧下に原液Mを充填すればよい(工程S5)。
【0017】
上記製造法においても、加圧剤と原液の順序が従来の方法と逆である。そしてそれらの充填工程の途中でピストン21のひび割れなどを容易にかつ正確に検出することができ、えられた二重エヤゾール装置の品質を確認することができる。
【0018】
図6は図5の製造法で製造された二重エヤゾール装置であり、図5の最終工程S5の後に、ステム23にノズル12を有する押しボタン11を取りつけたものである。ピストン21はそれぞれ上端および下端で原液用バルブ3および加圧剤充填バルブ7と干渉しない形状にされ、さらに原液Mや加圧剤Pに侵されないように三重ないし二重の層構造されている。
【0019】
【発明の効果】
二重エヤゾール装置の隔壁のピンホールやひび割れによる洩れを、加圧剤および原液の充填の途中で容易に、かつ正確にチェックすることができる。

[Industrial applications]
The present invention relates to a method for manufacturing a dual-eazole device. More specifically, the present invention relates to a method for manufacturing a double aerosol apparatus capable of filling contents while confirming that there is no leakage in a partition such as an inner bag or a piston.
[0002]
[Prior art]
Conventionally, an inner bag made of aluminum foil or a laminated film is attached to the opening of the pressure-resistant container to divide the container, and the undiluted solution to be sprayed is put into the inner bag, and a pressurizing agent ( Propellants) are used. In such a double aerosol apparatus, it is necessary to separate a stock solution and a pressurizing agent for extruding the stock solution, such as a liquefied gas such as LPG, or a compressed gas such as carbon dioxide gas or nitrogen gas, and fill them in separate rooms. In some cases, for example, they are used when they react when mixed together, or when the stock solution is food. Further, instead of the inner bag, there is also known a device separated by a piston sliding in the container.
[0003]
The inner bag or piston is a partition that separates the undiluted solution and the pressurizing agent, so its sealing performance is important. In particular, if there is a hole such as a pinhole or crack, the liquefied gas or compressed gas is mixed into the undiluted solution. Will be. Various methods for preventing such pinholes and cracks have been proposed, but none of them is perfect. For this reason, for example, the products are inspected by immersing them one by one in water, and assembled using only those which do not leak. However, such an individual inspection is very complicated, and leaks that occur only after assembly, such as leaks on the sliding surface between the piston and the container, cannot be found.
[0004]
The usual method of assembling the conventional double-eazor device is as follows: (1) First, the inner bag is temporarily attached to the container, or after inserting the piston, the undiluted solution is filled in the inner bag or the stock solution chamber above the piston. (2) A stock solution valve is attached to the container mouth (and the inner bag is fixed at the same time), and (3) A pressurizing agent is filled from a pressurizing agent filling valve. Before the inner bag is fixed with the undiluted solution valve, a so-called under-cup filling, in which a pressurizing agent is filled at a high pressure from a gap between the inner bag and the container, is also performed.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to eliminate the conventional step of inspecting a partition such as an inner bag or a piston one by one in advance, and to rationalize a production process of a double-eazole product.
[0006]
[Means for Solving the Problems]
The method for producing a dual-eazole device according to the present invention comprises the steps of (a) mounting a partition capable of transmitting pressure and a stock solution valve to a pressure-resistant container, (b) filling a pressurizing agent from a pressurizing agent filling valve, and (c) ) The liquid solution valve is opened to empty the liquid solution chamber, (d) the liquid solution chamber is closed and its internal pressure is measured. (E) The internal pressure of the liquid solution chamber is lower than a predetermined pressure, and there is no leakage of the partition walls. And then filling the stock solution from a stock solution valve.
[0007]
In the above-mentioned manufacturing method, the partition wall capable of transmitting pressure may be an inner bag that reversibly expands and contracts. In this case, the inner bag is inserted and fixed from the opening of the container together with the stock solution valve. Further, the partition wall capable of transmitting pressure can be a piston movable in the container. In this case, after the piston is inserted from the bottom opening of the container, the bottom opening is closed by the bottom plate.
[0008]
[Action]
When the propellant is filled in the propellant chamber, the partition wall is deformed or moved under the pressure, and the stock solution chamber contracts. When the stock solution valve is opened in that state, the internal pressure of the stock solution chamber falls to atmospheric pressure. Then, when the stock solution valve is closed with a pressure gauge, if there is a defect such as a pinhole or a crack in the partition wall, the pressurizing agent enters the stock solution chamber to generate a certain internal pressure. Therefore, the internal pressure is measured in that state, and if the internal pressure is lower than the predetermined pressure, it can be confirmed that there is no defect. If the internal pressure is higher than the predetermined pressure, it can be seen that there is leakage.
[0009]
【Example】
Next, an embodiment of a method for manufacturing a double aerosol apparatus of the present invention will be described with reference to the drawings. FIG. 1 is a process diagram showing one embodiment of the production method of the present invention, FIGS. 2 and 3 are partially cutaway perspective views and cross-sectional views each showing an example of a double eazole device obtained by the production method of FIG. FIG. 4 is a sectional view of a main part showing an embodiment of a tube according to the present invention, FIG. 5 is a process diagram showing another embodiment of the manufacturing method of the present invention, and FIG. 6 is a double view obtained by the manufacturing method of FIG. It is sectional drawing which shows an example of an eazor apparatus.
[0010]
FIG. 1 shows the outline of the manufacturing process of a double eazole device using an inner bag as a partition, from the left, a valve / partition mounting process S1, a pressurizing agent filling process S2, a stock solution chamber opening / inner pressure measuring process S3, S4, The process proceeds to the stock solution filling step S5. In the valve / inner bag mounting step S1, as shown in FIG. 2, an integrated valve 3 and inner bag 4 are inserted from the upper end opening 2 of the pressure-resistant container 1, and the valve 3 is inserted into the opening 2. In this step, the mounting cup 3a is fixed to the container 1 by crimping. The container 1 is a conventionally known one such as a pressure-resistant aluminum can, a tin can, and a glass bottle. The valve 3 is a known valve that can communicate between the inside and the outside by pushing or tilting a stem inserted into the center thereof. The inner bag 4 is formed by laminating two laminated sheets of aluminum foil and a synthetic resin film, etc., and bonding or heat-sealing the periphery thereof. The inner bag 4 is formed in a closed bag shape with the tube 5 at the lower end of the valve 3 interposed therebetween. I have. The valve 3 and the inner bag 4 are integrated via the tube 5, and the inner bag 4 is inserted through the opening 2 in a state of being elongated in the longitudinal direction as shown in FIG. Now it expands somewhat.
[0011]
The bottom plate 6 of the container 1 is provided with a conventionally known pressurizing agent filling valve 7. The pressurized agent filling valve 7 may be composed of, for example, a through hole formed at the bottom of the valve mounting cup 3a of the valve 3 for the undiluted solution, and a gasket closely contacting the lower surface thereof. After inserting the valve 3 and the inner bag 4 into the container 1 and fixing them, the pressurizing agent filling valve 7 first fills the pressurizing agent P such as a liquefied gas or a compressed gas without putting the undiluted solution (step). S2). FIG. 1 shows a case of a liquefied gas, and the liquefied gas P is divided into a liquid phase P1 and a gas phase P2, and the gas phase P2 compresses the inner bag 4 from the surroundings.
[0012]
Then, as shown in steps S3 and S4, a pressure gauge PG is attached to the valve 3 via a switching valve 8 or a stopper which can select between opening and closing. Note that the pressure gauge PG may be a pressure sensor or the like. Then, with the switching valve 8 switched to the open side, the stem of the stock solution valve 3 is pushed to communicate the inside of the inner bag 4 with zero air through the nozzle 9, and the inner bag 4 is emptied by the pressure of the pressurizing agent P2. (Step S3). Further, in this state, the switching valve 8 is switched to close the nozzle 9, and the internal pressure of the inner bag 4 is measured by the pressure gauge PG (step S4).
[0013]
At this time, if there is no pinhole or crack in the inner bag 4, the pressure in the inner bag 4 remains at O (atmospheric pressure). Therefore, a pressure of about 0.1 to 5 kg / cm 2 G is generated. Therefore, when the above-mentioned pressure is detected, it returns to the department which exchanges the inner bag 4 without filling with the stock solution, and when no pressure is detected, it shifts to the step S4 of filling the stock solution M under pressure. Then, by filling the stock solution M in the step S5 and further attaching the stem 13 and the push button 11 as shown in FIG. 3, the double aerosol apparatus A is completed. As shown in FIG. 4, a tube 5 at the lower end of the undiluted liquid valve 3 is extended to near the lower end of the inner bag 4, and a through hole 5a is formed in a side wall of the tube 5, or a porous material is used. By forming the tube 5, even if the inner bag 4 comes into close contact with the pressure of the pressurizing agent, a ventilation path is secured, and the pressure difference can be detected clearly. Therefore, the presence or absence of a pinhole or the like can be accurately detected.
[0014]
As described above, in the production method of the present invention, the pressurizing agent P2 and the stock solution M are filled in this order, and the presence or absence of a pinhole or the like in the inner bag 4 is detected by the pressure of the pressurizing agent P2 during the filling. It is not necessary to inspect the inner bags 4 one by one, and detection can be performed with a large pressure difference of 0.1 to 5 kg / cm 2 G. The above steps S1 to S5 can be sequentially performed by a conventional filling apparatus which performs filling while feeding by an index table type turntable as in a normal filling step. However, it can also be carried out using other devices, for example a rotary type.
[0015]
In the embodiment shown in FIGS. 1 and 2, the inner bag 4 is integrally attached to the valve 3, but the upper end opening of the inner bag 4 is placed on the bead 2a of the opening 2 of the container 1 as shown in FIG. Alternatively, it may be crimped integrally with the mounting cup 3a of the valve 3. Also in this case, first, the pressurizing agent is charged from the pressurizing agent filling valve 7, then the inner bag 4 is emptied, the inner pressure is measured, and finally, the inner bag 4 is filled with the stock solution P. Is the same. In FIG. 3, reference numeral 12 denotes a nozzle provided on the push button 11, reference numeral 13 denotes a stem, reference numeral 14 denotes a spring for returning the stem, reference numeral 15 denotes a valve housing which accommodates the stem and the spring 14, and is attached to the mounting cup.
[0016]
FIG. 5 shows a method of manufacturing a double azole system having a piston 21 slidable vertically in the pressure-resistant container 1 as a partition. This manufacturing method has a step S1 for mounting the valve 3 and the piston (partition wall) 21, a step S2 for filling the pressurizing agent P, a step S3 for opening the stock solution chamber, a step S4 for measuring the internal pressure, and a step S5 for filling the stock solution M. The process is substantially the same as the manufacturing method of FIG. 1 except that the stock solution chamber opening step S3 and the internal pressure measuring step S4 are separated. In addition, since the piston 21 is inserted from the lower part of the container 1, the bottom plate 6 is attached thereafter (step S1). The attachment of the valve 3 and the insertion of the piston 21 are the same in any case. In the pressurizing agent filling step S2, the pressurizing agent P2 is filled from the pressurizing agent filling valve 7 provided on the bottom plate 6, and at this time, the piston 21 rises while compressing the air in the stock solution chamber 22, and is balanced. Stop at the position (see the imaginary line in step S2). Then, by operating the stem 23 of the valve 3 to open the stock solution chamber 22, the air in the stock solution chamber 22 is released, and the pressure becomes equal to the atmospheric pressure (step S3). Further, a pressure gauge PG is attached to the stem 23 of the valve 3 to close the opening of the stem 23 and measure the internal pressure (step S4). At this time, if the piston 21 has cracks or if there is a gap between the piston 21 and the sliding portion between the container 1, the pressurizing agent leaks into the stock solution chamber 22 and enters. Therefore, the presence or absence of leakage can be detected by measuring the internal pressure of the stock solution chamber 22 with the pressure gauge PG (step S4). When it is confirmed that there is no leakage, the stock solution M may be filled under pressure from the valve 3 into the stock solution chamber 22 (step S5).
[0017]
Also in the above-mentioned production method, the order of the pressurizing agent and the stock solution is reverse to the conventional method. Cracks and the like of the piston 21 can be easily and accurately detected in the course of the filling process, and the quality of the obtained double-eazor device can be confirmed.
[0018]
FIG. 6 shows a double azole system manufactured by the manufacturing method shown in FIG. 5, in which the push button 11 having the nozzle 12 is attached to the stem 23 after the final step S5 shown in FIG. The upper and lower ends of the piston 21 do not interfere with the stock solution valve 3 and the pressurizing agent filling valve 7, respectively, and have a triple or double layer structure so as not to be affected by the stock solution M or the pressurizing agent P.
[0019]
【The invention's effect】
Leakage due to pinholes or cracks in the partition wall of the double-eazor device can be easily and accurately checked during the filling of the pressurizing agent and the stock solution.
