Abstract
A method of storing a product that contains a volatile component within a fluid storage reservoir formed with enclosing walls having a permeability that permits limited passage of the volatile component from the storage reservoir to the atmosphere, preferably with the method increasing the shelf life of the product stored, and a fluid storage reservoir with a first container containing the fluid product to be dispensed including the volatile component and a second container containing a sacrifice material including the same volatile component with an intermediate transfer wall shared by both the first container and the second container for transfer of the volatile component between the first container and the second container. The product preferably is a surface cleaner or a hand sanitizer including 30 to 95% ethanol.

A method of storing a product containing an initial concentration of a volatile component to increase shelf life of the product, the method comprising:
- storing the product in an enclosed first container defining an enclosed first interior within a first enclosing wall member having an inner surface of the first enclosing wall member open into the first interior and an opposed outer surface of the first enclosing wall member,
- providing a transfer segment of the first enclosing wall member over which the outer surface is in contact with a sacrifice material containing the volatile component in an initial concentration in the sacrifice material, the transfer segment having a first permeability that permits passage of the volatile component to the first interior of the first container through the first enclosing wall member from the outer surface to the inner surface,
- providing an escape segment of the first enclosing wall member over which the outer surface is in contact with atmosphere with the inner surface in contact with the product in the first interior of the first container, the escape segment having a second permeability that permits passage of the volatile component from the first interior of the first container through the first enclosing wall member of the first container from the inner surface to the outer surface.
A method of storing a product containing an initial concentration of a volatile component to increase shelf life of the product, the method comprising:
- storing the product in an enclosed first container defining an enclosed first interior within a first enclosing wall member having an inner surface of the first enclosing wall member open into the first interior and an opposed outer surface of the first enclosing wall member,
- providing a second container defining an enclosed second interior within a second enclosing wall member having an inner surface and an opposed outer surface,
- providing a sacrifice material in the second interior of the second container in contact with the inner surface of the second enclosing wall member, the sacrifice material containing the volatile component in an initial concentration,
- providing a transfer segment of the first enclosing wall member -to define at least in part the second interior of the second container such that the outer surface of the first enclosing wall member over the transfer segment is in contact with the sacrifice material in the second interior of the second container and the inner surface of the first enclosing wall member over the transfer segment is in contact with the product in the first interior of the first container
- the transfer segment having a first permeability that permits passage of the volatile component from the second interior of the second container to the first interior of the first container through the first enclosing wall member from the outer surface of the first enclosing wall member to the inner surface of the first enclosing wall member,
- providing an escape segment selected from the group consisting of:
- (a) a first escape portion of the first enclosing wall member of the first container with over which the inner surface of the first enclosing wall member is in contact with the product and the outer surface the first enclosing wall member is in contact with the atmosphere,. with the first escape portion of the first enclosing wall member of the first container having a second permeability that permits passage of the volatile component through the first enclosing wall member of the first container from the first interior of the first container to the atmosphere, and
- (b) a second escape portion of the second enclosing wall member of the second container over which the inner surface of the second enclosing wall member is in contact with the product and the outer surface of the second enclosing wall member is in contact with the atmosphere, the second escape portion of the second enclosing wall member of the second container having a third permeability that permits passage of the volatile component through the second enclosing wall member of the second container from the second interior of the second container to the atmosphere.
