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: An aerosol dispenser. The aerosol dispenser is made from materials which can go into a single recycling stream having a single class of materials, as defined by the Society of the Plastics Industry, and particularly may exclusively comprise Class 1 materials with no flammable product/propellant present.

Abstract: A method of warming food dispensable from an aerosol dispenser. The aerosol dispenser is made from materials which can go into a single recycling stream having a single class of materials, as defined by the Society of the Plastics Industry, and particularly may exclusively comprise Class 1 materials suitable for eating in a microwave oven. Consumer products, such as food, contained in the aerosol dispenser may be heated in a microwave oven prior to dispensing. Upon dispensing, food retains residual heat, and is suitable for eating or further cooking. Other heated products in the aerosol dispenser may be comfortably applied to the skin, used as air freshener, used for cleaning, etc. The aerosol dispenser may have indicia indicating the aerosol dispenser is suitable for microwave heating. The aerosol dispenser can have indicia indicating the aerosol dispenser is suitable for heating in a microwave oven. The indicia may be thermochromic, indiciating when a desired temperature has been reached.

Abstract: A plural preform assembly having nested preforms. The preforms are held together by an interference fit. The interference fit is provided by the friction between the preforms which occurs when the inner preform is inserted into the outer preform. At least one preform may have ribs extending radially towards the other preform. The ribs provided concentricity and interference to hold the preforms together during subsequent operations. The preforms may later be blow molded to provide a bag in bottle or similar container.

Abstract: An aerosol dispenser having a valve cup. The valve cup has an internal interlock, for attachment of a valve assembly thereto. A seal is disposed below the interlock. This arrangement provides the benefit that components of the dispenser may be inserted past the interlock, and still seal product therein under pressure. The interlock may comprise threads or a bayonet fitting. The valve cup may be injection molded as a preform.

Abstract: An aerosol container having an open neck at the top and a closed end bottom longitudinally spaced therefrom. The container has a valve cup and bag. The valve cup and bag are integral. The valve cup is attachable to the neck in sealing relationship. This arrangement provides for propellant to be disposed intermediate the container and bag. Product can be disposed in the bag for selective dispensing by a user actuated valve.

Abstract: An apparatus and process for molding workpieces usable for consumer products. The workpieces may be injection molded with a cavity formed by a core pin and have an undercut, such as internal threads, in the cavity. The apparatus has a drive system with a stripper plate mounted for alternatingly forward and retracting axial movement. The stripper plate is axially driven and drives a stripper sleeve barrel cam and a core pin base barrel cam, each having respective cam followers. The respective motions of the cam followers are superimposed on a stripper sleeve insert, which drives a core pin sleeve. The core pin sleeve is subjected to responsive three dimensional motion, allowing an internally threaded workpiece to be unscrewed from the core pin sleeve. The system does not require separate drives for the core pin sleeve, a single stripper plate drive being sufficient and further allows each mold cavity/core pin combination in a mold half to be unique.

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: A method of forming a preform, which is configured to be subjected to a subsequent forming process, the method comprising: providing a mold with a plurality of mold cavities, wherein the mold is made of a material having a thermal conductivity between about 52 watts per meter Kelvin and about 385 watts per meter Kelvin.

Abstract: A system for forming a plastic article, the system comprising a preform injection molding apparatus, comprising a mold, a plastic melt injection system, a sensor, and a controller, wherein: the first mold portion is made of a material having a thermal conductivity between about 52 watts per meter kelvin and about 385 watts per meter kelvin; the controller is configured to control the injection element to maintain the molten thermoplastic material at a substantially constant melt pressure, during filling of the mold cavities, wherein the substantially constant melt pressure is between about 2.76 megapascals (400 psi) and about 68.95 megapascals (10,000 psi); and the preform injection molding apparatus is designed to have a useful life of between one million and ten million injection molding cycles.

Abstract: A process for pressurizing a container assembly includes engaging the outer container around a neck of the outer container at a location between a shoulder of the outer container and a mouth of the outer container with a neck clamp device. The neck clamp device is used to support the outer container as the outer container moves from one location to a different location. An at least partial seal is formed about the neck of the outer container by engaging the neck clamp device with an outer bell member of a crimper-pressurized fluid fill head.
