記袋の外側に推進剤が置かれる。(Prior Art) Due to current environmental and economic reasons, there has been a strong demand to avoid using carbonized sulfur as an aerosol propellant. Therefore, it is desirable to produce an aerosol container that is formed by dividing a chamber in which the product to be sprayed is contained and a chamber in which the propellant gas is contained. In this type of container, the product to be distributed is stored in a bag made of plastic film, said bag being sealed against the container body, and a propellant placed on the outside of said bag.

開口周縁部を、缶胴の蓋の周縁部と缶胴の開口周
縁部の嵌合部分に挟み込んで袋を固定し、所要の
エーロゾル容器を構成したものが知られている。 For example, as described in Patent Application Publication No. 52-146383, the opening periphery of a bag disposed inside the can body is connected to the periphery of the lid of the can body and the opening periphery of the can body. It is known that the bag is fixed by being inserted between the joints to form the required aerosol container.

た。 When the opening periphery of the bag is held between the fitting part of the lid periphery and the opening periphery of the can body, elastic It is necessary to install a seal ring with a suitable seal between the fitting parts. However, even if such a seal ring is provided, if the fitting portion between the lid and the can body is only fitted in the circumferential direction, the degree of connection between the peripheral edges of the lid and the can body will be low;
There was a problem with the propellant gas being less tightly sealed.
そこで、缶胴の開口周縁部と蓋の周縁部とを二
重に巻締める構造とし、この二重に巻締める部分
に、袋の開口周縁部を同時に巻込むことにより、
シール効果の向上を図るこころみがなされた。 Therefore, by creating a structure in which the opening periphery of the can body and the lid are double wrapped, and by simultaneously wrapping the opening periphery of the bag into this double wrapping,
Efforts were made to improve the sealing effect.

れた。(Problems to be Solved) However, in order to form a suitable leak-proof double seam portion as described above, it is necessary to apply high pressure to the seam portion during the seaming process. As a result, it has been discovered that there is a tendency for the peripheral edge of the bag simultaneously rolled up within the seaming section to be cut.

る。 The present invention has been made in consideration of the above points, and is intended to prevent the open end of the product receiving bag that is rolled up at the same time from being cut within the seaming part when forming the seaming part (joint part). The purpose of the present invention is to provide an aerosol container with excellent sealing performance.

障壁（シール部材）として作用する。(Function) In the present invention, at the upper end flange of the container body,
A sealant is applied to form a seal-forming layer, such as cement or other suitable elastomer;
A film bag is then inserted into the container body. The upper end opening forming portion of the bag extends beyond the main body flange and is folded back along the outer surface of the main body. By doing this, when performing the seaming work, the applied sealant alleviates the force exerted on the bag, reduces the tendency of the bag to break, and allows the applied sealant to pass through the seaming part from the propellant chamber. Acts as a positive barrier (seal member) to prevent propellant leakage into the atmosphere.
（実施例）
以下、添付図面に従つて本発明の実施例を説明
する。(Example) Examples of the present invention will be described below with reference to the accompanying drawings.
第１図に於て、符号１０は通常の構造のエーロ

器本体１０は本体壁１１を有し、本体壁１１は下
方閉鎖端（図示なし）及び上方開口を有し、上記
開口は上端接合フランジ１２により形成される。 In FIG. 1, reference numeral 10 designates a container body used in an aerosol type container of conventional construction, the container body 10 having a body wall 11 having a lower closed end (not shown) and an upper closed end. It has an opening, said opening being formed by the upper end joining flange 12.

The opening forming part 14 of the bag 13 is sealed to the flange 1 with a normal sealant 18.
2, the sealant 18 may be in the form of cement or other suitable elastomer.

が固く緊締される。 After the bag 13 is inserted into the container body 10 and adhered with the sealant 18, the end plate 20 of a normal shape is attached to the container body 10 by a double seam portion (joint portion) 21.
can be attached in the usual way. In the normal method of double seaming, the flange 12 is attached to the end plate 2.
The double seam part 21 is folded into the hook part (curl part) formed by the peripheral part of the end plate as shown in FIG. Tightening roll (not shown)
By compressing the five metal layers in the seaming part 21 in the radial direction between
is tightened tightly.

緩和する働きをする。 As shown in FIG. 2, the sealant in the double seam portion 21 is located within the radially compressed portion of the seam portion, and therefore, during the tightening, the sealant in the double seam portion 21 It functions to alleviate the frictional force (rubbing force, that is, the force that caused damage to the bag in the past) exerted on the opening forming portion of the bag 13 from two adjacent metal layers.
袋１３の端部１７は巻締め部全体中を通過する
から、袋１３の材料は巻締め部２１内のシールを
形成することを助ける。勿論、シール剤１８は、
その通常のシール機能をも果す。 Because the end 17 of the bag 13 passes through the entire seam, the material of the bag 13 helps form a seal within the seam 21. Of course, the sealant 18 is
It also performs its normal sealing function.
さて第３図は、本発明による容器構造の少し変

る。 FIG. 3 now shows a slightly modified form of the container construction according to the invention, in which the sealant is applied to the flange 12 of the container body 10, as described above, instead of being applied to the flange 12 of the container body 10. It is applied to the inner surface of the body wall portion 16 in the joint formation 15. Similar to the previous example,
Extending along the joint forming portion 15 , the end portion 17 of the opening forming portion 14 extends beyond the peripheral edge of the flange 12 and is then bent back to follow the outer surface of the main body 10 .
この容器本体には、前例に就て述べたと同様に

形成され、よつて、袋は、何らかの破損が生じて
もシール剤１８によりシールされる。 The end plate 20 is attached to this container body in the same manner as described in the previous example to form a double seam part, but in the previous example, the sealant 18
is located between the two outer layers of the seam portion 21, whereas in this example between the two inner layers of the seam portion, i.e. between the portion 16 of the body wall and the chuck wall 22. The main seal between the bag 13 and the container body 10 is thus formed within the inner part of the double seam 21, so that the bag remains sealed by the sealant 18 even if any damage occurs. be done.
上記二例の何れに於ても、袋１３は散布される

ルされる。 In both of the above two examples, the bag 13 is configured to retain therein the product to be sprayed and to prevent propellant gas from penetrating through the walls of the bag 13 and into the product. It has barrier properties that can be prevented. At the same time, the propellant chamber located outside the bag 13 within the container wall is sealed to prevent propellant gases from escaping into the atmosphere.
シール剤は通常の方法により最少の労力を以つ
て容器本体に施与され得、また、何らの追加材料
も必要とされないから、袋と容器本体との間の確
実なシールを得る為に追加の費用を要することは
殆どまたは全くない。 Since the sealant can be applied to the container body by conventional methods with minimal effort and no additional materials are required, no additional material is required to obtain a positive seal between the bag and the container body. There is little or no cost involved.
