DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(28) Flow Tube hereinafter refers to a flexible tube structure used as a cartridge and as a pathway which holds a near constant cross section flow area, with the inner diameter of at least one end of the tube having approximately the inner diameter of a pneumatic inflation valve.

(29) Sealant Slime sealing agent hereinafter refers to a group of tire sealants that are defined as Sealant Slime or Sealant Slime sealing agents interchangeably. This sealants group has the ability to provide a durable and long-lasting solution for preventing and repairing punctures and are considered to provide a permanent repair as the repair tends to last until the end of the life span of an inflatable tire. These sealants are publicly known by a number of names, one of the more widely accepted generic names go by the name Slime, which comes from a product line and brand name Slime?. Manufacturers normally intend the use of these sealing agents as preventative means that are to be inserted into pneumatic tires and inner tubes prior to getting a flat. This is due to an inability to insert these sealants into pneumatic tires through the inflation valve core securely without danger of clogging of the valve core or injection apparatus and the process requiring labor and know-how for removing and installing the inflation valve core. This group of sealing agents, once installed in the tire, form a protective layer inside the tire. When a puncture occurs, the internal pressure of the inflated tire instantly pushes the sealant into the cavity of the puncture. Fibers and other solid particles such as micro mica platelets accumulate and create a mechanical plug. In many cases manufacturers combine the mechanical plugging materials together with polymers such as latex that bond the particles together in the mechanical plug and bond plug to the tire rubber in the cavity. The mechanical plug tends to form through the full depth of the cavity, which delivers a very durable fix, one which outperforms traditional repair methods. There are three common denominators unifying sealing slime sealants: 1. They are manufactured to cure multiple flats as they occur in a pneumatic tire. 2. These sealants are designed to go under local change of the sealant composition or structure when interacting with the hole in a pressurized tire. 3. Under current days injection technology they cannot pass securely through a valve core. In other words, they require valve core removal to be inserted. Various Sealant Slime sealing agents are manufactured using eco-friendly and biodegradable components. The combination of these together with the patent under consideration provides an ideal solution to the problem discussed.

(30) Sealing foam hereinafter refers to expanding foam that can be found in aerosol canister tire repair solutions. These sealing agents generally polymerize immediately upon injection immediately after leaving the holding canister. They have very low fiber and solid particles content and have low viscosity. This group of sealants is commonly used for emergency car tire repairs, and to some limited extent has been adopted in the cycling field.

(31) Hermetic Connector hereinafter refers to connectors that are gas tight when connected to a valve stem. These Hermetic connectors establish a safe, gas-tight seal, allowing fluid communication between two volumes, such as between a tire to be inflated and a source of pressured air. Use of such connectors prevents leaking that occurs in other common methods of sealant transfer.

(32) One-shot hereinafter refers to a single injection mold process. This also includes multi-layer injection molding technology.

(33) Charge hereinafter refers to the action of delivering materials, either compressed air or sealant agent, into the inflatable tire.

(34) The term Setting up refers herein to supplying sufficient gas pressure and gas flow rates required for adhering tubeless tire walls to the sidewalls of a tire rim.

(35) The term approximately refers to 30% to 250% of the described amount.

(36) The present invention allows for a portable device for transferring puncture-sealing liquids and more specifically Sealant Slime sealing agents into pneumatic objects such as bicycle tires, capable of successively inflating the inflatable tire and providing it with self-sealing properties that are capable of creating permanent seals and that are highly durable. In the case of repairing flat in pneumatic tires allowing the tire to seal instantly or after one or more rotations of the wheel. Furthermore, the device described in this document produces the most efficient means known today in permanently fixing flats in pneumatic tires. The invention provides a method for insertion of sealing slime sealing agents into pneumatic tires without the necessity for removing the valve core from the valve stem. This reduces the number of steps needed to complete a repair of a puncture in pneumatic tires. Furthermore, the steps needed are simpler and require much less technical skill than ever before in preventing punctures or permanently repairing existing ones.

(37) The device and its embodiment are designed to be as foolproof as possible, by being either constructed in a way that will only permit for a certain way of connection, or by being constructed in a way that will make connection order and direction of device irrelevant.

(38) The device and method in this document allow for dual function, one of Sealant Slime insertion and the second of inflating the pneumatic tire with sufficient gas pressure for use. The device achieves its technological ability by combining components from the following: Flow Tube, hermetic valve connector, unique one-way valves, seals, and existing liquid sealant agents from the sealant slime sealing agents group.

(39) All devices in the invention comprise of at least a Flow Tube, and at least one hermetic valve connector. These components will be described in detail in the following descriptions of the different embodiments.

(40) By applying air pressure (or any type of gas or mechanical pressure) through the end of the Flow Tube, which is not connected to the tire, Sealant Slime sealing agent, which is stored in the Flow Tube, will flow into the pneumatic tire via the tire valve stem. If desired the tire can then be further inflated. This is largely possible, due to the novel ability of this invention, to insert securely Sealant Slime sealing agents through the pneumatic tire valve stem while valve core is still in place further allowing gas pressure to accumulate in tire, and not escape the moment the device is disconnected from the valve stem.

(41) The device is normally fitted with hermetic connectors at either end, but in some instances valve connectors will be fitted only on one side. The Sealant Slime can be propelled, and the pneumatic tire inflated by gas, such as carbon dioxide, nitrogen, or compressed air from hand-pumps, electrical-pumps, canisters, and other unique sources such as donor car tires or gas-compressed bottles of soft drinks fitted with a dedicated valves and pressure release mechanisms for safety.

(42) The Flow Tube with the carefully designed hermetic valve connectors provides a near constant cross section flow area, with no abrupt changes in diameter, or treacherous pathways throughout the whole insertion path of the Sealant Slime. This design has a dual purpose. The first, to eliminate risk of premature polymerization of the sealant slime sealing agents in the injection apparatus. This is crucial with sealant slime sealing agents that are based on latex and other similar polymers, as they utilize friction and shear to elevate the energy within the sealant beyond a critical energy level that triggers immediate polymerization of the polymers in the sealant. Providing a near constant cross section with no obstacles for the flow of the sealant slime and no abrupt changes in diameter dramatically aids with maintaining laminar flow, lowers the shear and friction forces acting between the layers of the sealant. The second purpose of keeping a near constant cross section throughout the whole insertion path is to aid with alignment of fiber and other solid particles with the direction of the flow. Doing this allows long fibers that may in some cases be longer than the orifices that construct the inflation valve core to pass securely without clogging of the valve core or the injection apparatus.

(43) In addition to these two key contributions, which are relevant for the large majority of sealing slime sealing agents technologies found in the market today, some manufactures produce sealant slime sealing agents that rely on separation between the polymers and the suspension in order to solidify the polymers. With these type of sealant slime sealing agents keeping the near constant flow area cross-section and avoiding sharp edges will reduce to a minimum the occurrence of separation of polymers from the suspension in the flow path, thus preventing the premature polymerization that may clog the injection apparatus or the inflation valve core.

(44) If, due to various technical reasons, such as a requirement of large holding capacity of Sealant Slime in the device (e.g. one suitable for a car tire) it will not always be practical or preferable to hold a near constant cross section flow area throughout the entire flow-path, the Flow Tube diameter can change gradually in order to achieve the same desired effect and as long as there is a sufficiently long flow path with a near constant cross section to induce fiber alignment.

(45) In one embodiment, the device is shaped as a long tube-like structure containing a sealing agent such as Sealant Slime, with various terminating connectors and shapes as will be described below. Some embodiments, the tube-like, may be coiled into a spiral hose with at least two openings, one at either end of the tube. Multiple openings at each end are also possible, and will provide a more versatile insertion and gas source connection possibilities.

(46) Once connections are established on each end of the Flow Tube, a hermetically sealed configuration is established. Once the configuration is established, a propelling force from the pressure source will transfer Sealing Slime sealing agent into the tire through the inflation valve, while the valve-core is still in place.

(47) The flexible Flow Tube of the present invention can be partially or totally transparent. This enables the user to monitor the status of the sealant inside the tube.

(48) One possible operational downside of the prior art can happen when operating a similar device with a mechanical pump. During the back-strike action of the pump, if the tire valve pin is pressed open, a pathway and presence of backpressure can force unwanted sealant into the pump components. In one embodiment of the present invention, the valve on the Hermetic Connector is constructed with a shortened or missing valve pin thus not permitting the opening of the non returnable valve from said pump mechanism, hence avoiding said operational downside.

(49) Referring now to FIG. 4, showing a small volume flow tube having one valve (hidden) and two hermetic connectors (1 and 2) for road-bikes, which require a small quantity of sealant slime.

(50) Referring now to FIG. 5, showing a cross section of FIG. 4. The cross section reveals the valve 3 in addition to hermetic connectors 1, 2.

(51) Referring now to FIG. 6, showing a close up of one embodiment of the present invention, a cross section of the hermetic connector 6000 is disclosed. 611 is a male, check valve stem connector, that can be connected to hand pumps, electrical pumps and other standard sources of gas pressure. 612 is a spring that provides pressure and ensures a close (shut) state of two opposing check valves: 610 and 613. Valve 613 is in shut position, and has a uniquely designed depressing pin 615, which is structured especially to simultaneously press and open a pneumatic tire valve core depressing pin for about 2-3 mm (ideally to depress to the maximum of the allowed travel) and to open the injection device internal valve 613 simultaneously. In this figure, the upper valve 610 is in an open position. As previously described, valve 610 pin needs to be shortened, or as in this case, the pin is completely missing. This design of valve 610 is made in order to eliminate cases of fluid backflow from the device into a pump or other gas pressure source. This missing pin will allow valve 610 to be opened only in situations where high gas pressure is introduced through the male valve stem connector 611. The advantage of having a shorten or missing pin is that a depressing pin, which is normally present in pumps and other gas pressure source connectors, won't be able to mechanically open the valve 610, thus preventing entering of sealing material from tube 601, into the pumping devices. On the bottom side, there is a female valve connector composed of thread 614 and a rotating head 616.

(52) Referring now to FIG. 7, a schematic exploded view of the Hermetic connector 6000, showing all of its different parts. 601 is the tube-like part in which the Slime Sealant material is kept. 700 is a connector having a hose, where 601 is inserted. 704 tightens the connection between 601 and 700, preventing them to separate. 702 is the main body of the connector, and is inserted through 701 and 700. 701 helps holding handle 616, which includes thread 614. Between thread 614 and main body 702 there is a sealing ring 703, which ensures proper sealing. Inside the main body 702 there are the valve mechanisms, which comprise the male valve, stem connector 611, on which closer 705 is screwed. Adjacent to 611 is the previously described, missing-pinned valve 610. The body containing 610 is 707. 707 has a hole on which 706 can enter. Inserted around 706 there is the previously mentioned spring 612 that provides pressure and ensures a close (shut) state of two valves: 610 and 613. Also shown is valve 613 which is responsible for preventing the exit of the sealing material until the Hermetic connector is properly connected to the small volume flow tube (FIGS. 3 and 4). Finally, pin 615 is shown. 615 is a uniquely designed depressing pin, structured in length (between 2-3 mm) to simultaneously press and open a pneumatic tire valve pin, and to open the device valve 613 simultaneously. Once the Hermetic connector is assembled, connector 700 is capable of freely rotating on its axis. This feature provides the present invention with a degree of mobility that eases on the flow of sealant, preventing internal turbulence that might cause early polymerization.

(53) Referring now to FIG. 8 showing a coiled flow tube 601, having on one end 601a a hermetic connector 6000a and on a second end 601b a second hermetic connector 6000b, before linking it from one side to a hand pump 801 and to the other a bicycle tire 802, in a disconnected position. It is evident in details A and B that valves 610 and 613 are in a closed position, preventing the sealant contained in the device from escaping to the environment prematurely.

(54) Referring now to FIG. 9 showing a coiled flow tube device connected from one side to a hand pump 801 and from the other to a bicycle tire 802 through a valve 1, in a connected position, while the pump 801 is in a backstroke position. It is evident in details A and B that pin-less valve 610 in the male side 611 of the hermetic connector is kept in shut position due to the spring 612 until high pressure is introduced through the male valve connector 811 from the pump 801 or any other source of gas pressure. The female valve connector is connected to bicycle valve 617. Due to the uniquely designed pin 615 the valve core 3 is pressed open, simultaneously with the device valve 613.

(55) Referring now to FIG. 10 showing a coiled flow tube 601 device linking to a hand pump 801 from one side and to a bicycle tire 802 on the other side, through valve 617. The pump 801 is in a work stroke position introducing air pressure into the device and tire tube. It is evident in details A and B that the shortened pin with valve 610 is depressed into open position in the male side of the hermetic connector due to positive air pressure being propelled from the pump 801. The bicycle valve stem 1 is connected to female valve connector on the device and as a result the valve core 3 is pressed open and valve 613 in the device is forced open. At this point the pump, the device, and the pneumatic tire tube are in full fluid communication propelling sealant into the pneumatic tire.

(56) Referring now to FIG. 11 showing a bicycle frame 1101 fitted with a coiled flow tube 601 that has self-clamping properties.

(57) Referring now to FIG. 12 showing a close-up of coiled flow tube 601 on bike frame 1101 with flow tube hermetic connectors 6000a, 6000b.

(58) Referring now to FIG. 13 showing a close-up of a coiled flow tube 601 fastened by connecting the flow tube hermetic connectors 6000a, 6000b one to another making a secure connection of the device to the bicycle frame 1101, providing ease and security of transportation.

(59) Referring now to FIG. 14 showing a flow tube 601 used as described previously for setting up a tubeless bicycle tire receiving the needed air pressure and airflow rate needed from a spare car tire.

(60) Referring now to FIG. 15 showing a coiled flow tube 601 with an alternative source of pressured air 1501. A soft drink bottle fitted with a Schrader valve and a pressure limiter 1502 filled with gas pressure. In the present figure, the device 601 and compressed air bottle 1501 are positioned one next to the other. This comes to show the versatility of application and pressured air sources allowing for simple, eco-friendly, refillable, easy-to-use tire repair and inflation solutions.

(61) Referring now to FIG. 16 showing another use for the invention, the device 601 can be used to repair any inflatable object that needs sealing, repairing and inflation. In this example, the soccer ball 1601 can be repaired by connecting inflation pin 1602 to invention 801. Invention 601 can be attached to a regular ball foot-inflator 1603 in order to provide the necessary pressured-air.

(62) Referring now to FIG. 17 showing car 1701 in which the spare tire 1702 is used as an air pressure source, fixing a car flat tire 1703 through a coiled flow tube 601.

(63) Referring now to FIG. 18 showing another embodiment of the present invention. The tube containing the sealant is a long flexible tube 1801 (not coiled). In this case, since the tire 1802 requires a large amount of sealant, the long sealant-containing tube 1801 is more suitable. In addition, showing is a vehicle compressor 1803 that can be connected to a power source in the car 1804, like a lighter socket.

(64) Referring now to FIG. 19 showing a close-up of the long flexible tube 1801.

(65) Referring now to FIG. 20 showing a close-up of the long flexible tube 1801, fastened by connecting the flow tube hermetic connectors one to another making a secure connection of the device, providing ease and security of transportation.

(66) Referring now to FIG. 21 showing a detailed view of a gradual Flow Tube. A hermetic connector with a near constant cross section 3104 coupled to an air-tight flow tube 3103 that is coupled to a funnel unit 3102 that links to a sealant slime canister 3101 that has a pneumatic connector 3105 for air pressure.

(67) Referring now to FIG. 22 showing the gradual Flow Tube device 2101 in a bicycle workshop; set up to fill several bicycles 2201. The air source for this Flow Tube device is an air compressor 2202.

(68) Referring now to FIG. 23 showing a Flow Tube 601 connected to a bicycle tire 802, utilizing a high-pressure CO.sub.2 cartridge 2301 as the pressured air source. This is done by linking a pressure limiter 2302 between the CO.sub.2 cartridge 2301 and the Flow Tube 601. The pressure limiter 2302 has a tight passageway that may be 0.1-0.5 mm in diameter depending on the latex reactivity and length of the tight passageway. This produces sufficient pressure drop that prevents thermal and high pressure shocks from acting on the sealant, and by that prevents premature polymerization of the latex sealant.

(69) Referring now to FIG. 24 showing another embodiment of the present invention. Two points of view of a toothpaste shaped Flow Tube (2400 and 2401). Presented in Detail D is a unique design of a hermetic valve connector 2403, which, an important feature of the embodiment, is the fact that it is constructed as a one-piece injection. This gives the advantages of lowering manufacturing costs by using less materials, no moving parts for clamping, nor does this embodiment require a seal as a secure and sealed connection is achieved between the plastic threads 2404 and a pneumatic tire valve (not shown). Toothpaste flow tube 2400 is presented as a front view. 2401 is a side viewcross section A-A of the toothpaste Flow Tube 2400. Detail D gives a viewpoint of the one-piece hermetic valve connector 2403, which achieves a secure seal through its tight threads and with no moving parts. This embodiment is a one-time use tube. Once sealing is needed, the top part is cut along the imaginary line X-X. In another embodiment, this top part is configured as an easy opening mechanism.

(70) Referring now to FIG. 25, showing gradual Flow Tube toothpaste tube shaped 2402, with one closed sealed end 2501 and having a hermetic connector 2502, and an optional mechanical squeezer 2503 for ease of application. This embodiment is ideal for packaging of sealants, especially Sealant Slime. This embodiment provides ease of application with no spillage via the hermetic connector 2502. This embodiment will also provide a direct and simple means for application of Sealant Slime into pneumatic tires without the need to remove the valve core. This embodiment, as the others, will provide the dose needed for the tire, eliminating the user from having the need to make rough calculation about the amount of sealant needed, or making estimations about the amount of sealant that has entered the tire.

(71) FIG. 26 shows the toothpaste flow tube 2402 before connection to bicycle wheel valve 2601.

(72) Referring now to FIG. 27, showing another embodiment of the present invention. The flow tube 2700 containing the sealant is wider than the rest of the flow tubes shown in other embodiments in this document. This wider Flow tube can be used when applying sealants that are thinner than Sealant Slime or which are less prone to premature polymerization when passing through the valve mechanism, such as recent sealant technology developed. The wide flow tube may offer a better option for large sealant quantities as it will shorten the overall length of the Flow Tube, and possibly provide a more compact device. This utilizes two hermetic connectors and two one-way valves, which produce a concealed cavity for the sealant to be easily transported. This embodiment provides the pneumatic tire user a portable, efficient, cheap, lightweight sealant transfer and tire inflation solution.

(73) It is within provision of the device to use a one-way valve within connectors at one or both ends of the flow-tube that is designed to mate with Presta and Schrader, Dunlop or any other type valve.

(74) It is provision of the device that the invention can be configured in such a way that it will function correctly as long as the pressure received is from a source containing more than (>) 24 psi. This is important in cases the source of the pressured air is the spare tire of the car.

(75) The foregoing description and illustrations of the embodiments of the invention have been presented for the purpose& of illustration. It is not intended to be exhaustive or to limit the invention to the above description in any form, but rather to the contrary, the figures and embodiments come to show the diversity of the invention and it's different possible embodiments.

(76) It is provision of the device that the tube can have a straight or coiled configuration. The coiled configuration provides a better way to store the device, as shown previously in FIGS. 12 and 13. In either configuration, the total container area of the sealant enabled by the length of the tube together with the internal area created by the diameter of the tube is always enough for the specific item that needs to be fixed. It is logical that less sealant is needed in order to fix a bicycle wheel than a car tire. In each case, a specific combination of length of the tube and diameter of the tube will be calculated upon required volume of sealant slime, external constraints, and fiber content of the sealant slime.

(77) It is provision of the device that the uniquely designed depressing pin 615 which is structured in length (between 2.2-3.5 mm) is configured to press and open a pneumatic tire valve pin more than any regular inflator. The further opening of said valve pin enables better linear flow of the sealant, avoiding early polymerization and causing the valve to be stuck. The principal design will aim at achieving the maximum opening of the valve possible.

(78) Most of the embodiments of this invention are made of reusable, lightweight, replaceable, recyclable, refillable, serviceable components which will guarantee long-lasting products, cost-efficiency, and will provide the all-round eco-friendly solution that bicycle riders and other pneumatic tire users around the world are yearning for. In most embodiments, there is no need to throw away the device after a single use, just refill the device repeatedly for a safe sealant insertion.

(79) This invention comes as a direct opposition to the planned obsolete approach, which has badly infected all of our industries and as a result has taken a great toll on our environment. No need for wasteful pressurized cans, or tire repairs that only last for a few hours of use.
