The present invention provides means and methods for delivering a predetermined volume of a substance, within at least one body cavity of a subject, comprising a predefined volume for containing the predetermined volume of the at least one substance; a delivery end for placement in proximity to the body cavity; the delivery end comprises at least one orifice of diameter D [mm]; a valve mechanically connectable to the container, characterized by at least two configurations: (i) an ACTIVE CONFIGURATION in which the valve enables delivery of predetermined volume V.sub.sub [ml] of the substance; and, (ii) an INACTIVE CONFIGURATION, in which the valve prevents delivery of the predetermined volume V.sub.sub [ml] of the substance from the container to the body cavity; and a fluid tight chamber configured to contain predetermined volume V.sub.gas [ml] of pressurized gas at a predetermined pressure, P.sub.gas [barg].

The present invention provides a device for delivering a predetermined volume of a substance, within at least one body cavity of a subject, comprising a predefined volume for containing the predetermined volume of the at least one substance; a delivery end for placement in proximity to the body cavity; the delivery end comprises at least one orifice of diameter D [mm]; a valve mechanically connectable to the container, characterized by at least two configurations: (i) an active configuration in which the valve enables delivery of predetermined amount M.sub.sub of the substance; and, (ii) an inactive configuration, in which the valve prevents delivery of the predetermined amount M.sub.sub of the substance from the container to the body cavity; and a fluid tight chamber configured to contain predetermined volume V.sub.gas of pressurized gas at a predetermined pressure, P.sub.gas.

The present invention provides methods and a BFS/FFS system for delivering either one or more substances within at least one body cavity, characterized by a vial comprising V.sub.sub [ml] of said substances; said vail selected from a pierceable container, a blow-fill-seal and a form-fill-seal, having fluid inlet and a fluid discharging outlet of diameter D [mm], configured for placement in proximity to said body cavity; said fluid inlet configured by means of size and shape to interface in a sealable manner a puncturing member, configured to, upon coupling to said fluid inlet, piercing the same, thereby providing said substances in a fluid communication, via a valve, with a chamber configured to accept pressurized fluid at volume V.sub.PF [ml] and pressure P.sub.PF [barg]; said valve is commutable from an CLOSE to an OPEN CONFIGURATION within a short period of time, <500 milliseconds (dT); at said OPEN CONFIGURATION, said pressurized fluid flows from said chamber, via said fluid inlet, entrains said substances by one of the followings: (i) one portion m.sup.V.sub.PF/n, n=portion (%, v/v), m=1, (ii) a plurality of portions, m.sup.V.sub.PF/n, m2, or (iii) the whole V.sub.PF, n,m=1 erupts via said fluid discharging outlet to within said body cavity.

Pumps and dispensers having dosage control and various methods for actuating a pump or piston allow users to deliver a product from a container to be used by the user.

An extensible pesticide applicator is provided enabling application of both liquid and powdered insecticides to distal, out-of-reach areas. An extensible pole has a distal and a proximal end for manual wielding whereby a pair of nozzles is deployable proximal an out-of-reach habitat. Pressurization of ambient atmosphere into the extensible pole is enabled by a pump member and timed release of the pressurized ambient atmosphere to forcibly eject powdered and alternately liquid pesticide from the distal end is enabled by manual action effected to depress a trigger member. Direct application of pesticide is thereby enabled to distal and out-of-reach habitat without a user coming into proximity with the habitat or the pesticide released.

A liquid sprayer powered by an inflatable standup paddle board (iSUP), comprising: a container; a sprayer hose; and an air hose. The container is configured to hold a liquid, the sprayer hose comprises a spray nozzle and is configured to pass the liquid from the container through the spray nozzle. The air hose may be configured to connect to the container and to an iSUP. The air hose may comprise a flow regulator and one-way check valve. The flow regulator is configured to start, stop, increase, and decrease a flow of air from the iSUP into the container. The one-way check valve substantially prevents the liquid from entering the iSUP. The container may accept the flow of air from the iSUP when connected to the iSUP, such that the container is pressurized. When the container is pressurized, the spray nozzle passes the liquid out of the liquid sprayer.

A spray device comprises a diaphragm pump, a spray gun and a hose. The diaphragm pump comprises an air outlet to supply air flow, a casing and a pump assembly disposed in the casing. The spray gun comprises a housing and a Venturi tube arranged entirely inside the housing. The housing has an air inlet to receive the air flow supplied from the diaphragm pump and guide the air flow into the Venturi tube. The spray gun comprises a paint receptacle that receives and holds therein a paint material that is supplied into the spray gun and atomized to form paint droplets and entrain the air flow received from the diaphragm pump to allow the paint droplets to be sprayed onto a workpiece. The hose has two ends respectively coupled to the air outlet of the diaphragm pump and the air inlet of the spray gun.

An applicator for applying fibers to a surface is described herein. The applicator includes a body having a first end and a second end. The first end has a first opening configured to couple to a container housing the fibers and to receive the fibers from the container. The second end has a second opening for dispensing the fibers from the body. The applicator also includes an air flow generating member for creating an air current for propelling the fibers through the second opening as the fibres pass along a pathway between the first opening and the second opening. The fibers are directed along the pathway from the first opening towards the second opening and into the air current by gravity.

An atomizer is provided. When the atomizer provided by the invention is used, a fan blows air to a water outlet tube, part of the airflow in the water outlet tube passes through a pressurizing tube to enter a water tank to gradually increase the air pressure in the water tank, and liquid in the water tank is pressed into a water inlet tube under high pressure, flows into a guide tube along the water inlet tube and is sprayed out of the guide tube in a direction away from the fan; after flowing out of the guide tube, the liquid is blown out by the airflow blown from the fan into the water outlet tube on the periphery of the guide tube; and the fan is used for blowing air to the water outlet tube and increasing the pressure in the water tank.

The present disclosure provides devices for delivery of powder formulations and methods of manufacture and use of such devices.
