An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

The present application discloses a sealant container and a tire repair and inflation device using the sealant container. The sealant container comprises: a container body having an internal space for storing sealant and a container mouth with an inner wall; and a core component installed onto the container mouth and extending toward the internal space after installation. The core component has an outer end, an inner end, and a first channel between the outer end and the inner end inside the core component for passage of gas, wherein the outer end is provided with an interface, and the inner end is provided with at least one openable outlet to communicate with the internal space when the outlet is opened; and wherein the inner wall further defines a second channel for passage of sealant. The sealant container has a simplified structure and good sealing performance.

Apparatus for introducing air and/or sealant into a tire includes a container for the sealant having an inlet and an outlet, wherein the outlet is connectable to the inlet end of a hose whose outlet end is connectable to the tire to be filled and includes a pressure generation means which can be selectively connected to the inlet of the container or to the inlet end of a hose whose outlet end can be connected to the tire to be filled. The same hose is provided for the connection between pressure generation means and the tire to be filled, on the one hand, and between the outlet of the container and the tire to be filled, on the other hand, with respective couplings being provided at the pressure generation means, the inlet of the container, and the outlet of the container and at the inlet end of the hose which selectively enable the inlet end of the hose to be connected directly to the pressure generation means or the inlet of the container to be connected to the pressure generation means and the inlet end of the hose to be connected to the outlet of the container.

A portable compressor for a tire repair kit comprises an adaptor mobile or removable from a force transmitting use position, the adaptor having an upper edge projecting with respect to an outer side wall of the compressor and defining a seat for a container of sealing fluid, the upper edge being spaced in use from a surface on which the compressor rests; and being configured to define a side support by means of a force transmission to the compressor to oppose an excessive inclination of the container of sealing fluid during the injection of sealing fluid by means of pressurized air.

A device and method for storing tire repair material in or around the wheel barrel of a tire. Also, a device and a method for repairing a compromised tire using tire repair material stored in or around the wheel barrel of a tire. In some embodiments, the means for storing the tire repair material in or around the wheel barrel may comprise non-interconnected bays. Device embodiments may also comprise a tire repair material applying means (for example, means utilizing some form of propulsion and/or spraying). Thus, in some embodiments, the tire repair material may be applied to a compromised section of the inside surface of the tire, originating from the direction of the wheel barrel. In some embodiments, the device may also comprise a means for detecting a compromised tire and the punctured section thereof, as well as a means for signaling commencement of application of the tire repair material.

A cap unit for puncture repair comprises a check valve 6 for preventing a backflow of a puncture repair liquid supplied from a bottle container 2. The check valve 6 is disposed in a first flow path 3 used for taking compressed air from a compressor 8 into a bottle container 2. The check valve is formed by a ball valve 21 disposed in a valve housing zone Y which is located in a vertical passage part 15 of the first flow path 3 and between an upper opening 3U and a valve seat portion 20. The ball valve 21 is formed by a rubber-like elastic body having a specific gravity of 1.1 or more, and a rebound resilience of 15% or less.

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.

A method for repairing composite components includes installing a plug within a feature defined by a composite component, with the plug being formed from one or more neutral materials. Furthermore, the method includes infiltrating the composite component with an infiltrant to densify a repair region of the composite component, with the plug blocking a flow of the infiltrant into the feature. Moreover, after infiltrating the composite component, the method includes removing the plug from the feature.

A pneumatic valve adaptor includes a fast-releasable gas source connector, which includes a top source piece and a rotatable joint, the and at least one valve coupler. The top source piece is connected to a top end of the rotatable joint for receiving and feeding gas supplied from a gas source into the rotatable joint. The rotatable joint has a lower edge in which at least one first engagement section is formed. The valve coupler is provided, at a lateral external surface and a lower end, with at least a second engagement section and a valve connection section. The second engagement section is engageable with or disengage able from the first engagement section through rotation of the rotatable joint. The valve connection section is connectable to a pneumatic valve of an inflatable object for supplying and feeding the gas from the gas source into the inflatable object for inflation.

Provided is a puncture repair kit container that includes a container body including a holding portion that holds puncture repair liquid and an opening portion provided in one end of the holding portion, a cap mounted on the opening portion, a hose connected to a connecting portion provided in the cap, and an engaging portion that is provided in an outer surface of the cap and that engages the hose in an unused state by causing the hose to extend along a periphery of the cap.
