BACKGROUND INFORMATION1. Technical Field
Aspects of the present invention generally relate to packaged products, and more particularly relate to packaged products that include a personal care medium and a non-flammable volatile agent stored within an aerosol container.
2. Background Information
It is known to provide a packaged product that includes a personal care medium (e.g., a sunscreen medium, a tanning medium, a shaving aid medium, etc.) and a volatile agent stored within an aerosol container. The volatile agent may be included in the packaged product as a component of a propellant that aids in dispensing the personal care medium from the aerosol container. The volatile agent may additionally or alternatively be included in the packaged product to admix with the personal care medium to form an admixture having certain characteristics. The volatile agent typically is flammable. The use of a flammable volatile agent in a packaged product may be problematic for one or more reasons. For example, a packaged product that includes a flammable volatile agent stored within an aerosol container may be subject to government regulations that limit the size of the aerosol container, or that limit the types of materials that the aerosol container may be made of. It would be desirable to provide a packaged product that includes a personal care medium and a non-flammable volatile agent stored within an aerosol container, which packaged product achieves the same or similar results as a packaged product that includes a personal care medium and a flammable volatile agent stored within an aerosol container. Aspects of the present invention are directed to these and other problems.
SUMMARYAccording to an aspect of the present invention, a packaged product is provided that includes a personal care medium, a propellant, and an aerosol container. The personal care medium and the propellant are stored within the aerosol container. At least one of the personal care medium and the propellant includes a non-flammable volatile agent that includes at least one organofluorine compound.
According to another aspect of the present invention, a packaged product is provided that includes an aerosol container, a personal care medium, and a propellant. The aerosol container has at least a first reservoir and a second reservoir. The first reservoir and the second reservoir are fluidly separated by a barrier. The personal care medium is stored within the first reservoir of the aerosol container. The propellant is stored within the second reservoir of the aerosol container. The personal care medium includes a first non-flammable volatile agent that includes at least one organofluorine compound. The propellant includes a second non-flammable volatile agent that includes at least one organofluorine compound.
These and other features and advantages of the present invention will become apparent in light of the drawings and detailed description of the present invention provided below.
Referring now to the drawings, the present disclosure describes several embodiments of a packaged product. In each embodiment, the packaged product includes at least an aerosol container, a personal care medium, and a propellant.
Referring to
During manufacture of the packaged product 10, the personal care medium 16 is introduced into the top reservoir 34 of the container 12 at a pressure that may range, for example, from approximately one hundred eight (108) kPa (i.e., approximately one (1) psig) to approximately one hundred seventy (170) kPa (i.e., approximately ten (10) psig). Thereafter, the propellant 14 is introduced into the bottom reservoir 32 of the container 12 at a pressure that may range, for example, from approximately three hundred eight (308) kPa (i.e., approximately thirty (30) psig) to approximately four hundred forty-six (446) kPa (i.e., approximately fifty (50) psig). The valve 28 is in the closed position when the propellant 14 is introduced into the bottom reservoir 32 of the container 12. As a result, an imbalance in the forces on opposing sides 40, 42 of the piston 36 may cause the piston 36 to move along the axis 38 of the container 12 until an equilibrium state is reached; i.e., until forces on opposing sides 40, 42 of the piston 36 are equal to one another. During use of the packaged product 10, the user may selectively open the valve 28 (e.g., by depressing the nozzle 30) to dispense the personal care medium 16. When the valve 28 is opened, an imbalance in the forces on opposing sides 40, 42 of the piston 36 causes the piston 36 to move in a direction towards the top end portion 22 of the container 12, thereby dispensing the personal care medium 16 through the nozzle 30, until an equilibrium state is again reached. Each time the user selectively reopens the valve 28, the piston 36 moves further towards the top end portion 22 of the container 12, until the piston 36 encounters a mechanical stop, or until the pressure within the bottom reservoir 32 of the container 12 substantially equals atmospheric pressure.
In the embodiment illustrated in
The non-flammable volatile agent included in the propellant 14 includes one or more organofluorine compounds. The one or more organofluorine compounds may include: one or more trifluoropropene compounds; one or more tetrafluoropropene compounds; and/or one or more pentafluoropropane compounds. An example of an acceptable trifluoropropene compound is trans-1-chloro-3,3,3-trifluoropropene. Examples of acceptable tetrafluoropropene compounds include: 2,3,3,3-tetrafluoropropene; and 1,3,3,3-tetrafluoropropene. Examples of acceptable pentafluoropropane compounds include: 1,3-dichloro-1,1,2,2,3-pentafluoropropane; 1,1,1,2,2-pentafluoropropane; and 1,1,1,3,3-pentafluoropropane. The non-flammable volatile agent may additionally include nitrogen, carbon dioxide, and/or other acceptable materials. The non-flammable volatile agent embodiment may be selected so that the propellant 14 has one or more desired characteristics. For example, it may be desirable to provide a propellant 14 having a certain total pressure at a given temperature. In one embodiment, a propellant 14 having a total pressure of approximately two hundred thirty-two (232) kPa (i.e., approximately nineteen (19) psig) at approximately twenty-one degrees Celsius (21° C.) (i.e., approximately seventy degrees Fahrenheit (70° F.)) may be achieved using a non-flammable volatile agent that includes one and three-tenths (1.3) moles of a pentafluoropropane compound and seven-tenths (0.7) of a mole of a tetrafluoropropene compound. As the proportion of pentafluoropropane to tetrafluoropropene is increased, the total pressure of the propellant 14 at a given temperature generally will decrease.
