Abstract: A pressurized container A for under-cup charging which comprises a container main body 1 equipped with a bead portion 6 at a periphery of an opening at its upper end, a mounting cup 18 having a curved flange 18d which engages with the bead portion 6, a flexible inner bag which is interposed between the container main body 1 and the mounting cup 18. The inner bag 2 is equipped with a neck portion which abuts tightly against an outer peripheral surface of a rising wall of the mounting cup with predetermined fitting strength and a flange portion 11 which is disposed at the upper end of the neck portion and clamped between the curved flange and the bead portion. The flange portion 11 exhibits a sealing function when pressed to the inner surface of the curved flange 18d with a charging pressure at the time of under-cup charging and also when clamped between the curved flange 18d and the bead portion 6 after assembly.

Abstract: A pressurized container (A) for charging an undercup comprising a container main body (1) equipped with a bead portion (6) around an upper end open periphery thereof, a mounting cup (18) having a curve flange (18d) engaged with the bead portion (6) and an inner bag (2) having flexibility and interposed between the container main body (1) and the mounting cup (18), wherein the inner bag (2) includes a neck portion (10) in close contact with the outer peripheral surface of a rising wall of the mounting cup with a predetermined fitting strength and a flange portion (11) disposed at the upper edge of the neck portion and clamped between the curve flange and the bead portion, and the flange portion (11) exhibits a sealing action when pushed to the inner surface of the curve flange (18d) by a charging pressure at the time of charging of the undercup and a sealing action when it is clamped between the curve flange (18d) and the bead portion (6) after assembly.

Abstract: A degassing tool or a part thereof is attached to a degassed aerosol container such that a stem of the aerosol container is maintained in a pressed condition, and it is indicated on an outer surface of the degassing tool or the part thereof that degassing has been completed. Everybody can identify that the aerosol container is in a degassed condition even though degassing has been performed without forming any holes on the aerosol container itself.

Abstract: An aerosol product comprising a double-chamber container separated by a movable partition capable of dividing contents therewith, one spatial portion thereof being loaded with contents to be discharged and the other spatial portion being loaded with compressed gas for pressurizing. The compressed gas is a mixed compressed gas of at least two types of mixed gas, at least a part of the partition presents permeability of the compressed gas, and the mixed compressed gas selectively permeates the partition to be dissolved in the contents to be ready for discharge.

Abstract: A fixed-amount spray type aerosol container in which stem rubber is pressed against a mounting cap by a spring provided below the stem connected to a nozzle, and a tank is fixed between a guide bush that fixes the stem rubber and a housing, the container including a valve with a shape stabilizer installed between the guide bush and the tank. The container is nearly free from entry of external air and can spray the contents at a nearly constant amount until the contents nearly run out.

Abstract: A lid mounting structure for a pressure vessel for preventing a lid member 2 crimped to a curled portion 6 of an opening 5 of a vessel body 1 from being blown away by an abnormal rise of the internal pressure. A cut-away portion 8 or a through hole is formed in an outside wall of the curled portion 6, thereby locally reducing the elastic deformation resisting strength of the curled portion 6 with respect to expansion of the inside diameter of the opening to a level lower than that of the elastic deformation resisting strength of the lid member 2 in the inward radial direction.

Abstract: A measuring apparatus for determining dimensional data for use in designing a coupler which is manufactured to be fitted between the free ends of already assembled pipes in a pipe system is disclosed. A first joint on which a first arm is slidably supported is pivotally connected to one end of a rod adapted for gauging the distance between the points of bend in the coupler to be manufactured. A first joint on which a second arm is slidably supported is itself slidably mounted on the rod for movement therealong. With this arrangement, measurement of the angle defined by relative rotation of the rod about its axis to the arms is limited to one point, that is, at either of the joints. In addition, this apparatus permits easy installation on the site of measurement. The relative movement between the rod and the second arm and that between each arm and its associated attachment plate for engaging to the respective free end, are automatically measured by an electrical detection device.
