An apparatus and method for a cap for dispensing sealant from a pressurized bottle, to a tire stem valve, includes a cap body, a hose positioned within the cap body where the hose is configured to wrap around at least one storage groove inside a circumference of the cap. The at least one storage groove is helical and the cap also includes a diameter of the cap body where the diameter includes a length of the hose wrapped around the at least one storage groove.

An interface ring which is the interface between a container and an applicator comprising a circular socket with a plurality of laterally extending protrusions, a cylindrical thread being arranged above the socket, a central cylindrical opening extending through the interface ring in the centre of the thread and the socket wherein the thread presents a plurality of interruptions extending axially from the socket to the upper end of the thread, the interruptions dividing the thread into thread portions. It is an object of the present invention to provide an optimized interface ring. In order to achieve this object, the interface ring comprises deformable vertical ribs laterally extending mostly parallel to the radial axis of the interface ring wherein the deformable ribs deform when the interface ring is mounted on the outer rim of the cup of a valve or by other means on to the container. An interface ring with an increased grip of the interface ring on the valve. Therefore, much higher turning and buckling forces can be reached.

A device is described for facilitating the preparation of therapeutic foam e.g. for the treatment of varicose veins. A pressurised vial contains a sclerosant liquid, e.g., polidocanol solution, and a sterile gas which is readily absorbed by the body, e.g., carbon dioxide, oxygen or a mixture of these gases. The vial is provided either with a specialised stopper/seal into which a syringe nozzle may be inserted or alternatively a septum seal which may be penetrated by a hypodermic needle. The quantities of gas and liquid and the pressure in the vial are pre-set so that, on connection of a syringe to the vial, a predetermined volume of both gas and liquid is transferred to the syringe, with the intention that the syringe is then used to make a foam by known means. The use of the vial ensures that the ratio of gas to liquid in the foam is standardised, and also provides a convenient way of packaging the gas and liquid and of filling the syringe in a sterile manner.

A one-way valve (10) comprises: a valve housing (100) having a first end portion, a second end portion, a valve housing channel (110), and a stopper projection (108) provided within the valve housing channel (110); a valve body (200) having a first end portion, a second end portion, and a valve body channel (202) in fluid communication with the valve housing channel (110), the second end portion of the valve body (200) being snap-fit to the first end portion of the valve housing (100); and a sealing plug (300) slidably disposed within the valve body channel (202), wherein an inner diameter of the valve housing channel (110) is greater than an inner diameter of the valve body channel (202) and an outer diameter of the sealing plug (300), and a distance between the stopper projection (108) and the second end portion of the valve body (200) is greater than a longitudinal length of the sealing plug (300). A tire repair glue bottle (1) having a one-way valve comprises: a bottle body (20) containing glue; an air intake device (40) attached to the bottle body (20); a bottle lid (50) attached to the bottle body (20); a glue tube (30) provided within the bottle body (20) and having one end connected to the bottle lid (50); and an one-way valve (10), wherein the second end portion of the valve housing (100) of the one-way valve (10) is connected to the other end of the glue tube (30).

A nozzle assembly provides an adapter configured for insertion into a pressurized container, wherein a nozzle has been removed from the pressurized container. A tubing has a first end connected to the adapter and a second end. A discharge nozzle is releasably connected to the second end of the tubing.

A foam transfer or dispensing device is described which dispenses foam from a source of foam, typically a pressurised canister, and which enables efficient purging or air and an initial volume of foam from the device to ensure foam sterility and quality when a syringe is filled from the device. The device comprises a foam inlet arranged for communication with a source of foam, a foam pathway in fluid communication with the foam inlet and comprising a foam outlet, arranged for engagement by a syringe nozzle; and a waste outlet in fluid communication with the foam pathway. The foam pathway comprises a tubular projection arranged to extend through the foam outlet and into a syringe nozzle when a syringe is connected to the foam outlet, which improves the efficiency of the purging process and prevents pooling of air or foam. The device further comprises a means for restricting displacement of material through the waste outlet, so that the user can control the volume of foam that is wasted.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

Embodiments of the present invention provide foam skin care product (e.g., soap) dispensers and corresponding compositions. An example foam skin care product dispenser includes a reservoir that holds, under pressure, a skin care product composition, including one or more propellants. During a dispense, a dispense valve is opened to release some of the skin care product composition from the reservoir into a dispensing (e.g., flow) path. Once released, the skin care product composition at least partially foams to form foamed skin care product (e.g., foamed soap).

A device to allow for the continuous spraying of pressurized liquid from an aerosol spray can at any angle required, and in locations that can only be accessed through an openings through which an aerosol spray can does not fit, all while automatically preventing backflow of the pressurized liquid through the device.
