Abstract: An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

Abstract: A valve for an aerosol dispenser. The valve has a housing as a chassis for other components of the valve. The housing perimetrically joins the valve to an outer container for the aerosol dispenser. The housing has a hole with a moving valve stem to selectively dispense product, upon actuation. The housing, or portions thereof, may be crystallized, to provide strength and dimensional stability, to reduce leakage.

Abstract: A multi-piece valve stem. The multi-piece valve stem allows for interchangeability of component parts, without requiring several stems to fit related valves, as are commonly used for aerosol dispensers. The multi-piece valve stem also provides for assembly of valve stems having a larger head, and thus more seal area, than can occur with a single piece valve stem, as is conventionally used. Smaller stem bore diameters are also possible with a multi-piece valve stem.

Abstract: An aerosol container for an aerosol dispenser. The aerosol container has an outer container. The outer container has a closed end bottom and a longitudinally opposed threaded open neck. The open neck has one or more pawls or ratchets disposed near the neck. The pawls or ratchets allow a complementary valve to be threaded onto the neck. The valve has complementary ratchets or pawls. The ratchet and pawl combination co-acts to impede or even prevent reverse rotation and subsequent removal of the valve. The outer container may be made from a preform having the ratchets and/or pawls integrally molded as part of the injection molding process. A valve having a housing may have ratchets and or pawls integrally molded as part of the injection molding process.

Abstract: A preform suitable for blow molding into for an outer container usable for a pressurized aerosol dispenser. The preform has a longitudinal axis and a closed end bottom, an open neck. The neck has threads for accepting a valve having complementary threads. At least one pawl or ratchet is operatively juxtaposed with the periphery of the preform. The at least one pawl or ratchet allows onward rotation of the complementary valve in an onward direction, and prevents detachment of the valve in a reverse rotation direction. Any such preform can be blow molded into a corresponding outer container, and any such outer container can be blow molded from a corresponding preform.

Abstract: An outer container for an aerosol dispenser. The outer container has a closed end bottom and a longitudinally opposed open, open neck. A complementary valve can be received in the neck. A cap overlays the valve and engages the outer container, valve, or both, to prevent removal of the valve. The cap may have threads, ratchets/pawls, splines, spikes, bayonet fitting or combination thereof to engage the valve or outer container.

Abstract: A threaded valve for an aerosol container. The threaded valve comprises a housing, a moving assembly disposed in the housing, threads suitable for threadable onward attachment onto a complementary neck of an outer container for an aerosol dispenser and a plurality of pawls and/or ratchets disposed on and extending from the housing. The pawls and/or ratchets allow onward rotation of the valve onto the complementary neck and impeding rotational detachment of the valve in a reverse direction.

Abstract: An aerosol dispenser having a valve for dispensing product through a valve stem. The valve stem is protected by a sheath, to reduce breakage. The sheath extends equal to or above the height of the valve stem, to absorb axially compressive loads and side impact loads. The sheath can occur in the aerosol dispenser, an aerosol container, an outer container, a preform and/or in the valve. The aerosol dispenser can include bags, pistons and dip tubes.

Abstract: A method of making an aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The method has the steps of sealing the valve to the product delivery device and outer container at respective annular welds or other bonds joining the valve to the product delivery and to the outer container. The welds, or other bonds may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes. Suitable welds include spin welds.

Abstract: A pressurized container usable for a pressurizable contain, such as an aerosol dispenser, an aerosol dispenser made therewith and preform therefor. The preform/container/dispenser has a neck at the top. The neck has upper and lower portions. The lower portion transitions into a shoulder, which flares outwardly. The shoulder, in turn, transitions into a sidewall. The lower neck portion/shoulder and/or upper part of the sidewall are cystallized. The invention also comprises a preform for making such a pressurizable container and an aerosol dispenser made therewith.

Abstract: The present invention relates to improvements in prevention of discoloration of thermoplastic starch materials and their blends with other thermoplastic materials.

Abstract: Disclosed herein are degradable sachets useful for enclosing a consumer product, such as, for example, shampoo, conditioner, soap, toothpaste, bar soap, and detergent. The sachets of the invention have a moisture vapor transmission rate (MVTR) of less than about ten grams per square meter per day (g/m2/day) at 37° C. and 90% relative humidity (RH), and can disintegrate into pieces sufficiently small to pass through a one millimeter sieve, within two years after first and continuous exposure to water and microorganisms.
