A polymeric aerosol dispenser that is recyclable. The recyclable polymeric aerosol dispenser including all polymeric components. These components being selectively either fixedly joined or separably joined based on the material composition of the component. Further, components may be selected for their density and, thus, their ability to float or sink during the recycling process. The recyclable polymeric aerosol dispenser is designed to minimize its impact on the PET recycling stream and to align with industry recyclability guidelines.

The present invention relates to a method for manufacturing a pressurizable cylindrical vessel for use in a pressure control system for maintaining a constant predetermined pressure in a fluid container configured to dispense when in use a fluid contained in said fluid container at said constant predetermined pressure, characterized in that the manufacturing is by injection moulding. The invention also relates to a method for assembling a pressurizable fluid container configured to dispense when in use a fluid contained in said container at a constant predetermined pressure. In addition, the invention relates to a pressurizable cylindrical vessel, a pressurizable unit, a pressure control system, a bottom plate and a dispenser; as well as their methods of manufacturing. In a final aspect the invention relates to uses of said parts in a bag-on-valve type packaging or metal can type packaging.

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.

An aerosol dispenser, an outer container for an aerosol dispenser, and a preform for an outer container. The aerosol dispenser, outer container, and preform each have a neck including a crimp ring. The crimp ring may be configured to receive a valve cup, which is clinched thereto. The crimp ring includes one or more vents. The vents may be used to control overpressurization within the dispenser. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue overpressurization. The vents allow propellant and/or product to be released therethrough in the event of overpressurization.

A container, a nebulizer and a use of an indicator device are described, where the container comprises an indicator device fixedly mounted on the bottom of the container, the container is arranged within the nebulizer and the container can be detached by grabbing the indicator device.

An aerosol dispenser, an outer container for an aerosol dispenser, and a preform for an outer container. The aerosol dispenser, outer container, and preform each have a neck including a crimp ring. The crimp ring may be configured to receive a valve cup, which is clinched thereto. The crimp ring includes one or more vents. The vents may be used to control overpressurization within the dispenser. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue overpressurization. The vents allow propellant and/or product to be released therethrough in the event of overpressurization.

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.

An aerosol dispenser, an outer container for an aerosol dispenser and a preform for an outer container. The aerosol dispenser, outer container and preform each have a neck, which in turn has a crimp ring, to receive a valve cup clinched thereto. The crimp ring has slots which act as vents therethrough. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue internal pressurization. The vents to relieve propellant and product therethrough in the event of overpressurization.

An aerosol dispenser, an outer container for an aerosol dispenser and a preform for an outer container. The aerosol dispenser, outer container and preform each have a neck, which in turn has a crimp ring, to receive a valve cup clinched thereto and a lower neck potion upon which the crimp ring is mounted. The lower neck portion extends between the bottom of the crimp ring and a shoulder which transitions into the sidewalls. The crimp ring preferably has a greater axial length than the lower neck portion. This geometry allows flexibility in the thickness throughout the thickness of the entire neck. The geometry advantageously minimizes distortion of the neck in the event of overpressurization.

The present disclosure relates to an aerosol container made of plastic, the container having a neck, the opening of which is closeable in a pressure-tight manner by a valve unit that can be actuated by a pushbutton, the container being Tillable with a liquid or gaseous propellant and a liquid to be sprayed. The aerosol container can be an injection cast preform with an elongated tubular preform body. The preform body is closed by a dome-shaped convex preform base, beyond which an integrally formed stand region projects in an axial direction. The preform body adjoins the opening of the neck at the opposite axial longitudinal ends of the preform body.
