容器材質が弾性限度内であれば歪と応力とは比
例した関係にあることから、一定の内圧を加えた
場合の各部分の容器縦方向の歪分布を測定するこ
とにより、容器に生じている応力を把握すること
が出来る。本考案者等が、従来のエアゾール容器
について歪分布を測定したところ、第５図に示す
ように側壁と底壁の接合部、特に側壁の下部内側
に大きな応力が生じており、その他の部分にはあ
まり応力が発生していないことが分かつた。 If the container material is within its elastic limits, strain and stress are in a proportional relationship. Therefore, by measuring the strain distribution in the vertical direction of each part of the container when a certain internal pressure is applied, it is possible to determine the amount of strain occurring in the container. Stress can be understood. When the present inventors measured the strain distribution of a conventional aerosol container, as shown in Figure 5, a large stress was generated at the joint between the side wall and the bottom wall, especially on the inside of the lower part of the side wall, and in other parts. It was found that not much stress was generated.
そこで、前記のようにエアゾール容器を構成す

エアゾール容器を得ることが出来、応力の小さい
部分の肉厚を削減して材料の使用量を節減するこ
とが出来たのである。 Therefore, by configuring the aerosol container as described above, it is possible to obtain an aerosol container that has sufficient strength to withstand stress, and the amount of material used can be reduced by reducing the wall thickness of the portion where stress is small. It was possible.
（考案の効果）
この考案によれば、内圧によつて生じる応力が
大きい側壁と底壁との接合部分、特に側壁下部の
肉厚を増大させて、内圧に充分に耐えることの出
来る強度を有したエアゾール容器を得ることがで

能となるので、容器全体としては材料の使用量が
節減され、コストの低下を図ることが出来る。(Effects of the invention) According to this invention, the thickness of the joint between the side wall and the bottom wall, where the stress caused by internal pressure is large, especially the lower part of the side wall, is increased to provide strength that can sufficiently withstand internal pressure. Since it is possible to obtain an aerosol container with a high temperature and reduce the wall thickness other than the joint portion, the amount of material used for the container as a whole can be reduced, and costs can be reduced.
