ている。In this aerosol can, when the overcap 7 is attached to the intermediate member 6, as shown in Fig. 3 (showing the positional relationship between the cap 7 and the intermediate member 6 at the III-III portion in Fig. 2), In the portion, the step portion 6d of the intermediate member 6 is in contact with the step portion 7b of the overcap 7 (positioned below the locking piece 7a), but in the remaining portion, the step portion 6d of FIG. IV
(Showing the positional relationship between the overcap 7 and the intermediate member 6 at a location), the cutout portion 7c is provided to facilitate the attachment / detachment of the overcap. It is an open passage and is in communication with the outside.

ャップの内外は連通する構成になっている。The structure of the overcap of the aerosol can is not limited to the above-mentioned ones, but there are various structures, but in order to allow the overcap to be easily attached and detached, a partial locking structure and an overcap are required. Since the cutout portion 7c is provided with a structure such as the deformable portion or a loose locking structure is provided, the inside and outside of the overcap are all communicated with each other.
（考案が解決しようとする問題点） 上記エアゾール缶においては、缶胴に所定量の内容
品、例えば濃縮コーヒーを充填した後、マウンティング
カップを固着し、次にその注出筒から所定量の炭酸ガス
を注入し、缶内圧が適正であることを確かめたあと、中
間部材とオーバーキャップをぶせる。(Problems to be solved by the invention) In the above-mentioned aerosol can, after the can body is filled with a predetermined amount of contents, for example, concentrated coffee, the mounting cup is fixed, and then a predetermined amount of carbonic acid is discharged from the pouring cylinder. After injecting gas and confirming that the internal pressure of the can is proper, cover the intermediate member and the overcap.
ところが、量産されたこれらのエアゾール缶のなかに
は、消費者の最初の注出時に内容品を注出できないもの
があり、又、一旦使用後に、後日、再び注出しようとし
て注出筒を押し下げても注出できないものがある。However, some of these mass-produced aerosol cans do not allow the contents to be poured out at the time of the consumer's first pouring, and even if the pouring barrel is pushed down after being used, the pouring barrel is pushed down again at a later date. Some things cannot be poured out.
本考案は、このような欠陥のないエアゾール缶の提供
を目的とする。The present invention aims to provide an aerosol can without such defects.
上述した注出不能は、これまでのエアゾール缶の構

又はバルブの液通路に内容品、例えば濃縮コーヒー液の
固形分が付着して該通路を閉塞するためであり、これ
は、次のような実験から充分肯認されるところである。It is considered that the above-mentioned inability to pour is caused by the structure of the conventional aerosol can, that is, the inside and outside of the overcap communicate with each other. That is, the contents, for example, the solid content of the concentrated coffee liquid adheres to the liquid passage of the pouring cylinder or the valve to block the passage, which is sufficiently confirmed by the following experiment.
前記従来の構成をもつエアゾール缶10缶に市販の濃縮

た。10 aerosol cans having the above-mentioned conventional structure were filled with commercially available concentrated coffee liquid (solid content: 23% by weight), and the can internal pressure was 1 kg /
Carbon dioxide gas was injected to reach cm 2 , and the concentrated coffee liquid was slightly discharged from the injection cylinder 4, and the intermediate member 6 and the overcap 7 were attached to the extraction cylinder 4 with the concentrated coffee liquid remaining.

した。These 10 cans are divided into 2 groups of 5 cans each, leaving the group A as it is, seal the lower peripheral edge of the overcap 7 attached to the aerosol can of the Otsu group with gum tape, and then apply clay on it to overcap The internal / external communication structure of the.
これら両群の缶を、夫々温度55℃、湿度24％の恒温室
に２日間放置し、その後オーバーキャップを取り外し、
注出筒を押し下げ、濃縮コーヒー液が注出可能か否かを
調べた。Each of these cans was left in a temperature-controlled room at a temperature of 55 ° C and a humidity of 24% for 2 days, and then the overcap was removed.
The dispenser was pushed down and it was examined whether the concentrated coffee liquid could be dispensed.
乙群のエアゾール缶は５缶共注出できた。しかし、従
来構成の甲群では、１缶はどうにか注出出来たが、残り
４缶は全く不備であった。We were able to pour out 5 aerosol cans of group B. However, with the conventional group A, although one can was managed to be poured out, the remaining four were completely defective.

た。Can diameter 50 mm, can height 15 formed by drawing and ironing
A 0 mm bottomed can body 1 was filled with a predetermined amount of a concentrated coffee liquid having a solid content of 23% by weight, and a mounting cup 3 having a spout cylinder 4 and a valve mechanism 5 was fixed to an open end of the can body by a conventional method. After injecting a predetermined amount of carbon dioxide gas from the pouring cylinder 4, the concentrated coffee liquid is sprayed from the pouring cylinder to increase the internal pressure of the can to 4 to 5 Kg / cm.
2. The (intermediate member (pour-out cylinder actuating member)) 11 was attached to this, and the overcap 12 was attached to the intermediate member 11.
このオーバーキャップ12と中間部材11が、従来のオー
バーキャップ７、中間部材６（第２図）と相異する点は
次の通りである。The overcap 12 and the intermediate member 11 are different from the conventional overcap 7 and the intermediate member 6 (FIG. 2) in the following points.
中間部材11の上部円筒壁11bにねじ部11aを設けたこ

環状に突出片12bを設け気密保持構成としたことであ
る。The upper cylindrical wall 11b of the intermediate member 11 is provided with a threaded portion 11a, the inner peripheral surface of the overcap 12 is provided with a threaded portion 12a to be screwed with the threaded portion 11a of the intermediate member 11, and the overcap is further provided. Among them, a step portion (corresponding to 6d in FIG. 3) facing the step portion 11c extending diametrically outward from the lower end of the upper cylindrical wall 11b of the intermediate member 11 (corresponding to 7b in FIG. 3). That is, the protruding piece 12b is provided in an annular shape to have an airtight holding structure.
この中間部材11にオーバーキャップ12をかぶせ、ねじ

プ内外は遮断される。When the intermediate member 11 is covered with the overcap 12 and the screw portions 11a and 12a are screwed together, the protruding portion 12b of the overcap is pressed against the step portion 11c, and the overcap 12
Is locked to the intermediate member 11 in an airtight state, and the inside and outside of the overcap are shut off.
このように構成されたエアゾール缶を量産し、その中
から任意100缶を取出し、オーバーキャップを外し注出
筒を押し下げて注出筒内に濃縮コーヒー液を残留させ再
びオーバーキャップをかぶせ、室内に30日間放置した。Mass-produce aerosol cans configured in this way, take out any 100 cans from them, remove the overcap, push down the pouring cylinder, leave the concentrated coffee liquid in the pouring cylinder, cover it again with the overcap, and put it inside the room. I left it for 30 days.
比較例として、第２図に示す従来構成のオーバーキャ
ップを用いたものを100缶製造し、同様に室内に放置し
た。As a comparative example, 100 cans were manufactured using the conventional overcap shown in FIG. 2 and left in the room in the same manner.
上記放置後、濃縮コーヒー液の注出を行ったところ、
本実施例の100缶は、そのすべてが容易に注出できた
が、比較例では100缶のうち88缶のみが一応注出できた
に止まった。After the above standing, when the concentrated coffee liquid was poured out,
All of the 100 cans of this example could be easily poured out, but in the comparative example, only 88 out of 100 could be poured out.
なお上述の実施例では、中間部材11の段部11cに対向
