Detailed Description The following description focuses on embodiments of the present invention applicable to aerosol containers.

In an embodiment according to Fig. 1 a schematic view of an aerosol container 10 according to an embodiment is shown. The container has main body 12, a closed bottom end 14 and a closed upper end 16. While the bottom end 14 is formed integrally with the main body 12, the upper end 16 is closed by means of an aerosol valve 100.

The container may be of cylindrical shape. The upper end 16 is provided with a circumferential groove 18, as will be described further in accordance with Fig. 5. The valve 100 is arranged inside the container 10, and the valve 100 has an actuator 20 that is provided outside the container 10, connecting to a valve stem extending through the open upper end 16. The valve 100 is opened by applying a downward force on the actuator 20. When the actuator 20 is pressed downwards towards the container 10, the valve 100 is opened and gas is allowed to escape from the container 10 through a dip tube 130 inside the container 10.

The valve 100 comprises a stabilizer 120 as is shown with reference to Fig. 2 and 3. The stabilizer 120 is formed as a body 160 and is equipped with a through hole 10 15 20 25 30 170 for allowing the valve stem 150 to extend through the stabilizer 120. The body 160 of the stabilizer 120 forms a valve housing that acts as a cover for the aerosol valve 100 in the same sense as prior art valve cups. Hence, the valve stem 150 extends through the valve housing 160via the hole 170. The valve stem 150 is connected to an actuator and is extending inside the valve housing. When the valve stem 150 is subject to a pressing force in a direction downwards, i.e. towards the valve housing, an interior channel inside the valve 100 is ?uidly connected with the interior of the cylinder such that the content of the cylinder is allowed to be discharged through the interior channel of the valve stem 150.

The periphery of the stabilizer 120 is provided with a plurality of resilient members 140 that extends outwards in a radial direction. In one embodiment the periphery of the stabilizer 120 is provided with 12 members 140. It should be understood by a person skilled in the art that the number of members 140 could vary depending on design parameters.

Each resilient member 140 forms a spring, such that it will always strive to retum to its idle shape and form. If the resilient members 140 are urged radially inwards, i.e. when the stabilizer 120 is mounted in an aerosol container, they will press outwards to rest against the inner surface of the container 100.

The springs 140 may be provided as plastic ?anges, extending outwards. The interface where the ?anges are connected to the body 160 thus forms a hinge. ln the shown embodiment the stabilizer is circular. ln other embodiments, the stabilizer 120 may be of triangular shape, in the shape of a square or in any other form.

With further reference to Fig. 4, an embodiment of the stabilizer is partly shown. ln an embodiment, as shown in Fig. 5, the stabilizer is partly shown when attached to the aerosol container 10. The inside wall of the upper end 16 of the main body 12 is provided with a circumferential groove 18. When mounted the circumferential groove 18 is snapped together with the stabilizer 120, to provide a secure and rigid attachment. The springs 140 of the stabilizer thus snaps into the groove, providing a fixated position of the aerosol valve relative the container. A 10 15 20 25 30 circumferentíal portion of the body 160 Will be press-fitted in the container such that a sealing is achieved.

A method 200 for providing an aerosol container Will now be described With reference to Fig. 6. In a first step 210, a metal blank is extruded into a hollow body. In a particular embodiment, the hollow body has a main body 12, a closed bottom end 14 and an open upper end 16. The upper end is provided With a circumferentíal groove 18. ln a subsequent step 220, a valve 100 is arranged Within the Walls of the upper end 16. The valve has a valve body, and a projecting actuator 20 or valve stem 150 that opens the valve 100 When it is depressed. The valve 100 is arranged such that the actuator 20 is facing the opening of the upper end 16. The valve further comprises a stabilizer 120, Where the periphery of the stabilizer 120 is provided With a plurality of resilient members 140 that extends in a radial direction. ln a next step 230, the open upper end 16 is sealed against the valve body such that the upper end 16 is closed. The plurality of resilient members 140 of the stabilizer 120 snaps together With the circumferentíal groove 18 of the hollow body 12 of the container, thus creating a secure and robust position fixation. The circumferentíal groove 18 and the resilient members 140 keeps the stabilizer 120 in a perfect position such that a circumferentíal portion of the body 160 seals against the inner Wall of the container 10 and prevents the parts from sliding relative each other. Thus, the When using the stabilizer 120 for an aerosol valve 100 the need of a mounting cup, valve cup or sealing gaskets is gone.

A method 300 for filling an aerosol container Will now be described With reference to Fig. 7.

In a first step 310, all the substance except the propellant is added to the hollow body 12 of the container 10. The substance is usually in the form of a liquid or foam, such as insecticides, deodorants, hair spray and paints. ln a subsequent step 320, the open upper 16 end is sealed against the valve body such that the upper end 16 is closed as described in the method according to Fig. 6.

In a next step 330, the propellant is injected under pressure through the valve 100. The propellant may be in the form of a liquified gas, or a compressed gas. The propellant may for example be mixtures of volatile hydrocarbons, typically propane and n-butane.

Although the present invention has been described above With reference to specific embodiments, it is not intended to be limited to the specific form set forth herein. Rather, the invention is limited only by the accompanying claims and, other embodiments than the specific above are equally possible Within the scope of these appended claims.
