Definitions

  • This invention relates to a fluid and air dispensing apparatus.
  • Figure 1 illustrates a tire sealant and air dispenser apparatus with a sealing mechanism
  • Figure 2 illustrates further details of the sealant dispensing assembly of the apparatus shown in Figure 1 ;
  • FIG 3 illustrates further details of an embodiment of the sealant dispensing assembly of the apparatus shown in Figure 2;
  • Figure 4 illustrates further details of a second embodiment of the sealant dispensing assembly of the apparatus shown in Figure 2.
  • the apparatus and method is particularly applicable to the injection of tire sealant through a tire valve stem into a tire of a vehicle and it is in this context that the apparatus will be described. It will be appreciated, however, that the apparatus and method has greater utility since it can be more generally used to dispense a fluid and air from a fluid container and can be used with other articles in which it is desirable to be able to seal and/or re-inflate the articles.
  • the apparatus and method also may be used for any application where a fluid might be dispensed using pressurized air as an energy source.
  • similar applications for the apparatus includes paint and coating systems, measured fluid injection devices, oiling devices, and others.
  • the apparatus and method provides a simple method and mechanism of sealing a container of sealant fluid.
  • the mechanism uses balls, such as rubber balls, pressed into injection molded tubes that seals the container of sealant fluid and prevents back pressure of the item being repaired and inflated from forcing the sealant fluid and air back into the sealant container.
  • the mechanism is simple and reliable and the rubber balls are available as a commodity item from various worldwide suppliers.
  • the injection molded tubes are simply inlets and outlets normally formed into a tire sealant dispensing cap. In operation, when compressed air is applied to the inlet, the balls are moved from a seating position in the tubes and the sealant and air is then injected into the tire with no restriction.
  • Figure 1 illustrates a tire sealant and air dispenser apparatus 12 with a sealing mechanism for repairing and inflating a item 10, such as a tire.
  • the apparatus 12 may include a compressor 11 that has a hose 12 that is connected to an air inlet 13 of a sealant dispensing assembly 14.
  • the compressor may be powered by a power source such as through a power cord that couples to a cigarette lighter of an automobile as shown in Figure 1.
  • the sealant dispensing assembly 14 may have an air and sealant outlet 15 that is coupled to the item being repaired and inflated using the apparatus.
  • the compressor (when powered) pushes compressed air through the hose 12 and the compressed air enters into the sealant dispensing assembly 14 and then the air with the sealant fluid (from inside of the sealant dispensing assembly 14) is pushed into the item being repaired and inflated using the apparatus.
  • the compressor serves the purpose of inflating the item being repaired and inflated and pushing the sealant fluid within the sealant dispensing assembly 14 into the item being repaired and inflated using the apparatus.
  • the apparatus shown in Figure 1 has a sealing mechanism (described in more detail below) that seals the sealant dispensing assembly so that sealant fluid does not leak out of the sealant dispensing assembly during storage, can prevent air with sealant from entering the compressor and prevents the pressure within the item being repaired and inflated using the apparatus from forcing the sealant fluid and air back into the sealant dispensing assembly.
  • a sealing mechanism described in more detail below
  • FIG 2 illustrates further details of the sealant dispensing assembly 14 of the apparatus shown in Figure 1.
  • the sealant dispensing assembly 14 may include a sealant container 20 that contains a sealant fluid used to repair the item being repaired and inflated using the apparatus.
  • the sealant fluid may be a ethylene glycol based sealant fluid or a glycerin based sealant fluid.
  • the sealant dispensing assembly may also dispense any liquid sealant including propylene glycol based or sealants based on other antifreeze agents.
  • the assembly 14 has the air and sealant outlet 15, such as a hose with the appropriate connector to couple to a tire, and the air inlet 13 into which the compressed air is introduced into the sealant container.
  • the assembly 14 may further include a cap 26 that incorporates the ball seals and inlets/outlets (described in more detail below in Figures 3 and 4) and provides a resting surface on which the sealant dispensing assembly 14 can rest when the apparatus is being used to repair and inflate the tire.
  • Figure 3 illustrates further details of an embodiment of the sealant dispensing assembly of the apparatus shown in Figure 2.
  • the sealant container 20 may be removably coupled to the cap 26 by a connecting mechanism 30 which may be a threaded mechanism wherein the sealant container 20 has a set of threads that can be screwed into the threads of the connecting mechanism.
  • the cap 26 may include an air inlet 13 connected to a passageway that is coupled to an inlet seal 32 that may be a ball seal 33 wherein the ball may be a rubber ball.
  • an inlet seal 32 that may be a ball seal 33 wherein the ball may be a rubber ball.
  • the ball 33 When compressed air is not entering the air inlet 24, the ball 33 is pressed into a tube/against the end of the tube so that the sealant fluid cannot leak out of the sealant container.
  • the ball is frictionally fit into the end of the tube.
  • the inlet seal may have a seat 34 wherein the ball can optionally rest against the seat so that the sealant fluid cannot leak out of the sealant container.
  • the ball 33 When the compressed air is being injected into the air inlet, the ball 33 move upwards (as shown by the arrow) being expelled from the tube (that may be an injection molded tube) away from a sealing position into the sealant container 20 due to the air pressure and permits the compressed air to enter into the sealant container 20. Alternatively, the ball 33 may be captured in the tube so that the ball does not enter into the sealant container 20. In both embodiments, the sealant and air outlet 15 is constructed to prevent the ball 33 from exiting the sealant container.
  • a ball 36 of the outlet seal (that may be a rubber ball) can rest against a tube end and or be frictionally fit in the tube (when the outlet seal does not have a seat) or against a seat 37 so that the sealant fluid does not leak out the sealing container.
  • the ball When the mixture of the compressed air and sealant fluid is being injected into the tire, the ball is expelled from the tube (that may be an injection molded tube) or seat by the air pressure that allows the mixture of the air and sealant fluid into the tire to repair and inflate the tire.
  • the outlet 15 has a cutout portion 39 that permits the compressed air and fluid to flow past the ball 36 when the ball has been expelled from the tube or seal by the compressed air (the dispensing position).
  • the ball 36 of the outlet seal 35 may be captured in the tube in one embodiment or captured in the outlet 15 in the other embodiment.
  • the outlet seal 35 also can prevent the air pressure in the tire from forcing air and/or sealant fluid back into the sealant container since the ball 36 will be forced back into the tube, against the end of the tube /against the seat 37 due to the tire pressure. It is noted that the inlet and outlet seals 32, 35 are relatively simple and can be made of readily available materials.
  • Figure 4 illustrates further details of a second embodiment of the sealant dispensing assembly 14 of the apparatus shown in Figure 2.
  • the cap 26 has the connecting mechanism 30, the inlet seal 32 and the outlet seal 35.
  • the inlet seal 32 is a valve core seal 42 that prevents sealant fluid from leaking out during storage and prevents the sealant fluid from fouling the compressed air source.
  • the outlet seal 35 has the ball 36 and seat 37 (along with the tube in which the ball is captured).
  • both the inlet and outlet seals 32, 35 are adjacent each other in a neck portion 40 of the cap 26.
  • an outlet cap 38 may be placed over the air and sealant outlet and help to further seal the sealant dispensing assembly 14.
  • the outlet has the cut-out portion 39 that permits the compressed air and fluid to move past the ball 36.
  • the outlet cap 38 may be threaded and screw onto the air and sealant outlet.
