DETAILED DESCRIPTION OF THE INVENTION

[0022] The present invention relates to a single-layer cartridge, and a process for producing a plastic single-layer container included in the cartridge. The single-layer cartridge comprises a plastic single-layer container, a seal and a nozzle-shaped cap or stopper, wherein the single-layer cartridge can be connected to a soft mist inhalation device or inhalation atomizer. The single-layer cartridge may be further fitted into and/or protected by a metallic or aluminum canister.

[0023] FIG. 1 shows a complete view of the single-layer cartridge comprising the single-layer plastic container and a nozzle shape cap or a stopper. FIG. 2 shows a cross section in the direction of the single-layer plastic container center axis 10, wherein the container wall based on single layer 1 has space 2 for a pharmaceutical formulation solution inside the container. The single-layer cartridge has a cap or stopper lock key 5 projections disposed on the end of the container neck 7 where the single-layer plastic container opening inlet space of cap or stopper 3 nozzle and sealing surface 4 are located. The single-layer plastic container has a transfer bed 8 in between the container neck and slant surface 9 of the container. The transfer bed provides support for the nozzle shaped cap or stopper snap action.

[0024] FIG. 3 and FIG. 4 show the nozzle-shaped cap or stopper, wherein the dispensing or soft mist inhalation device or draw-off connection portion has already penetrated the sealing foil on the top side of the top portion 18 and the outlet part 21 of the cap.

[0025] The inlet sealing slant provides cannula-free moment space 22, the free moment space 22 penetrates into the neck space insertion connection portion 6 which is sealed with silicon material 20 and is joined to the container sealing surface 4 on its cap or stopper. The stopper is held at its top side by a flanged over portion of the upper end of the stiff casing. The cartridge can be sealed by the stopper with the tight sealing disc 24 which closes to the open end of the capillary tube insertion portion.

[0026] FIG. 5 and FIG. 6 show a sealing disc 24, which is disposed between the upper edge of the container and inlet/outlet space 25 on silicon type material disc inside of the cap or stopper of the cartridge. Disposed between the upper edge sealing surface 4 of the container and the underside of the stopper is the sealing disc 24 having cap locking tab 15. The cap or stopper is held at its top side by a flanged over portion of the upper end of the stiff casing. The cartridge can be sealed by a nozzle-shaped cap or stopper with the tight sealing disc 24 which closes the open end of the capillary tube insertion portion. The cartridge comprises a capillary tube inside a cannula. The capillary breaks the seal of the cap outlet 20 and goes inside the space of container 2.

[0027] FIG. 7 shows a complete view of a compressed container with the negative pressure effect on the container wall after usage of medicine. When the capillary tube is inserted inside the cartridge, it breaks the seal of the cap or stopper and goes into the cannula while breaking the cap outlet seal 20, and the capillary tube enters inside the container space 2. With the usage of medicine, the container wall 1 is compressed because of the negative pressure. Because the pressure inside the container is lower than the surrounding pressure, this mechanism increases the vacuum inside the container. The compressed negative pressure effect can clearly be seen on the container wall.

[0028] The single-layer cartridge according to the current invention can be used with a soft mist inhalation device as shown in FIG. 3 and FIG. 4 of US20190030268 inhalation atomizer comprising a blocking function and a counter. The typical inhalable device can be carried anywhere by the patient, since it has a cylindrical shape and a handy size of less than about 8 cm to about 18 cm long, and about 2.5 cm to about 5 cm wide. The nebulizer sprays a defined volume of the pharmaceutical formulation solution out through small nozzles at high pressures, so as to produce an inhalable aerosol.

[0029] The typical inhalation atomizer comprising the block function and the counter described above for spraying a medicament fluid is depicted in FIG. 8. The inhalation atomizer comprising the block function and the counter described above is preferably a portable inhaler that requires no propellant gas.
