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 combined lid/valve device including a lid, for a pressurised product dispensing container, and a valve mechanism, in which the lid is provided with a so-called upper face and a so-called lower face, in which the lower face of the lid includes a base provided with a skirt for receiving the neck of a pocket containing the product to be dispensed, the base forming a housing for the valve mechanism consisting of a dispensing tube and a sealing gasket, the sealing gasket mounted on the dispensing tube snap-fitting into a through-hole between the upper face and lower face of the lid and allowing an outlet end of the dispensing tube to project beyond the upper face of the lid.

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 device for dispensing pressurized air and/or tire sealant from a pressurized can. The device comprising a cap body, a depressor button with a lock clip, and a hose positioned within the cap body attached to the pressurized can. The lock clip locks the depressor button in the compressed position for ease during use, while a shield element keeps the depressor button in the non-compressed position for safety during non-use. The hose provides an extension to attach to a tire stem valve, while being stored and attached to the cap body of the device.

Vessel having sterile contents containing in predetermined proportions (i) a foamable liquid and (ii) a gas or gas mixture other than air. The contents are at a pressure above atmospheric pressure. The vessel has an outlet which is adapted to cooperate with a syringe nozzle and which has associated with it a breakable seal or a valve.

An aerosol product diffuser assembly comprises: a diffuser block (1) comprising an annular casing (2) inside which a cam actuator (3) is mounted axially mobile, a control lever (10) provided with a planar body (12) making it possible to control the diffusion of the aerosol liquid said cam actuator (3) comprising: (i) an axially mobile cam follower plate (4); (ii) an aerosol bottle nozzle housing (5), arranged on the cam follower plate (4); (iii) a duct (6a) connected to the nozzle housing and enabling the liquid to diffuse to a discharge point of the aerosol liquid, the control lever (10) being pivotably mounted on the annular casing (2), and the cam actuator (3) being able to be pushed axially towards the aerosol bottle by at least one pivoting cam (15).

A wrist mounted toy is described wherein a pressurized canister containing a string foam compound, or other pressurizable liquid with mid to low viscosity, is attached to a vessel containing a check valve. A geared-trigger mechanism allows for the user to expel the fluid at a pressure and rate dependent on the pressure he or she places on the lever. Additionally, the actions of removing and replacing the air and fluid canisters provide the user with a more interactive experience compared to a simple load and shoot toy. Many variations can be adapted to the toy to allow for a wide range of uses. The toy allows the user to enjoy a device which resembles the Marvel character's shooter more closely and discharge the fluid to quite a distance.

A puncture repair kit includes a container configured to house puncture repair liquid; a hose configured to be connected to the container and carry the puncture repair liquid into a tire; a compressor configured to supply compressed air for supplying under pressure the puncture repair liquid in the container through the hose; and an assistor configured to correct a tilt of the container when the container is connected to a tire valve via the hose and pendent from the tire valve.

An article includes an adapter having a flow channel extending through it, where the adapter includes a base, a neck, a bendable segment attached to the base and neck and positioned between the base and neck, and a plunger attached to the neck or bendable segment and extending within the flow channel in the bendable segment.

An apparatus for dispensing pressurized air and/or tire sealant from a pressurized can. The apparatus comprising a nozzle and a locking element for the nozzle and/or a cap including a free length of hose that is positioned within the cap. The locking element locks the nozzle in the non-dispensing position for safety during non-use or in a dispensing position for ease of use. The hose provides an extension for the nozzle for hard to reach places, and stores fully wound within the cap, such as along the inner circumference of the cap.
