  As shown in FIG. 5, this type of apparatus is provided with a pressure-resistant bottle a containing a puncture sealing agent, a high-pressure air intake b1 through which high-pressure air is introduced, and a sealant outlet b2 through which the puncture sealing agent is taken out. An air supply hose c1 of a compressor c, which is a high-pressure air source, is connected to the high-pressure air intake b1 and includes one end of an air valve of the tire T at the sealant outlet b2. The other end of the feeding hose e connected to is connected.

  The high pressure air from the compressor c is fed into the pressure resistant bottle a from the high pressure air intake port b1, thereby taking out the puncture sealing agent from the pressure resistant bottle a, and passing through the sealant outlet port b2 and the feeding hose e to the tire T. To be sent to. The tires are also pumped up by supplying high-pressure air.

  Further, since this type of device is used in an inverted state in which the bottom of the pressure bottle a is facing upward, a leg portion b3 is integrally formed at the lower end of the sealing agent take-out unit b.

  However, the leg b3 needs to be formed with a large diameter in order to stably hold the pressure bottle a in an inverted state. Therefore, when connecting the hoses c1 and e to the high-pressure air inlet b1 and the sealant outlet b2 at the puncture repair site, there is a problem that the leg b3 becomes an obstacle and impairs the connection workability. When the high-pressure air intake b1 and the sealant take-out port b2 are formed so as to largely protrude from the leg b3, foreign matter may enter the high-pressure air intake b1 and the sealant take-out port b2 during storage, or an external force May cause damage. Moreover, the storage property of the feeding hose e at the time of storage is poor, and there arises a problem that the storage property of the apparatus is impaired.

  Therefore, the present invention enables stable holding in an inverted state, while preventing foreign matter from entering and breaking into the high-pressure air intake and the sealant outlet, and facilitating the connection work of each hose. An object of the present invention is to provide a tire puncture sealing agent feeding device that can accommodate a feeding hose for convenience and improve the storability of the device.

In order to achieve the above object, the invention of claim 1 of the present application is a pressure-resistant bottle that can store a puncture sealing agent, a high-pressure air intake that can be attached to the pressure-resistant bottle and into which high-pressure air is introduced, and a seal that takes out the puncture sealing agent.

  In the present invention, as described above, the lid base member that holds the pressure bottle in an inverted state is detachably formed. Therefore, it is possible to easily connect the hose to the high-pressure air intake port and the sealant outlet port by removing the lid base member while allowing the lid base member to have a large diameter and enabling stable holding in an inverted state. Can do. Further, since it is not necessary to project the high-pressure air intake port and the sealing agent extraction port from the lid base member, it is possible to prevent foreign matter from entering or breaking into the high-pressure air intake port or the sealing agent extraction port.

  In addition, the small tower portion of the sealant take-out unit has a smaller diameter than the pressure bottle and the lid base member, thereby forming a storage space in which a supply hose is wound around and stored. Moreover, the lid base member has an annular leg portion projecting from one surface of the disc-shaped base portion and having a flat end surface. Therefore, during storage, the lid member is mounted inward so that its mounting surface faces the pressure bottle, so that the circumference of the feeding hose wound around the storage space can be held by the annular leg portion. It becomes possible to suppress the rewinding of the hose. That is, the feeding hose can be accommodated conveniently without being compact, and the storability of the apparatus can be improved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view illustrating a case where the puncture sealing agent feeding device of the present invention is used for emergency repair of punctures, and FIG. 2 is a cross-sectional view showing an enlarged main part thereof.

  As shown in FIG. 1, the puncture sealing agent feeding device 1 (hereinafter referred to as device 1) includes a pressure-resistant bottle 2 that can accommodate the puncture sealing agent A, a sealing agent take-out unit 3 that can be attached to the pressure-resistant bottle 2, A feed hose 4 that feeds the puncture sealing agent A in the pressure-resistant bottle 2 to the tire T and a lid base member 10 that is detachably attached to the tip of the small tower portion 8 of the sealant take-out unit 3 are provided.

  The pressure-resistant bottle 2 is a bottle-shaped pressure-resistant container having a pressure resistance of preferably 800 kPa or more, and a mouth for taking out the sealing agent is opened at the tip of the neck 2A.

  Next, as shown in FIG. 2, the sealing agent take-out unit 3 is a small-diameter tower having a high-pressure air inlet 20 through which high-pressure air is introduced and a sealing agent take-out port 25 through which the puncture sealing agent A is taken. 8 and a large-diameter head 9 connected to one end side (the upper end side in FIG. 2) of the small tower portion 8 through a step.

  An attachment recess 13 is formed at the tip of the head 9 to insert and fix the neck 2A of the pressure bottle 2. The mounting recess 13 has an inner screw for screwing the neck 2A of the pressure bottle 2 on its inner wall surface, and a packing material is disposed between the bottom surface of the mounting recess 13 and the neck 2A. The Further, in the present embodiment, the mounting recess 13 has, for example, a cylindrical boss portion 15 that rises from the bottom surface and reaches the neck portion 2A of the pressure-resistant bottle 2, and an annular wall portion 7 that surrounds the periphery of the boss portion 15. Is protruding. The annular wall 7 is elastically fitted with a cap 6 that prevents the puncture sealing agent A in the pressure-resistant bottle 2 from flowing out during storage or the like.

  The sealing agent take-out unit 3 includes a first flow path 17 extending from the high-pressure air intake 20 and reaching the inside of the pressure bottle 2, and the first flow path 17 is formed inside the pressure bottle 2. Only the second flow path 18 extending from the inside of the pressure-resistant bottle 2 to the sealant outlet 25 is formed.

  The high-pressure air inlet 20 and the sealant outlet 25 are opened at the tips of nipple-like hose joints protruding from the side surfaces of the small tower portion 8. A compressor air supply hose 5a, which is a high-pressure air source 5, is detachably attached to the high-pressure air intake port 20, and one end of the feeding hose 4 is detachably attached to the sealant outlet 25. . In this example, the high-pressure air inlet 20 and the sealing agent outlet 25 are formed with a 90 ° phase difference.

  Next, in this example, the first flow path 17 includes the horizontal flow path portion 17A extending linearly from the high pressure air intake port 20 and the conduction port 16 intersecting the horizontal flow path portion 17A. It is formed from a vertical flow path portion 17B extending on the bottom surface of the recess 13 and extending to the air inlet 24 that opens between the boss portion 15 and the annular wall portion 7. The other end of the horizontal flow path portion 17A is formed as an openable / closable portion 22 that can be opened and closed by a lid. The opening / closing part 22 is normally closed. In this closed state, the device 1 can inject a puncture sealing agent and high-pressure air into the tire. The second flow path 18 extends downward from an outlet 27 that opens at the tip of the boss 15, and the other end is connected to the sealant outlet 25. As described above, the first and second flow paths 17 and 18 can communicate with each other only inside the pressure-resistant bottle 2 by opening the air inlet 24 and the outlet 29 in the pressure-resistant bottle 2.

  Next, the lid base member 10 is detachably attached by being screwed to the tip of the small tower portion 8. Specifically, in this example, as shown in FIG. 2, a small-height locking portion 30 is provided at the tip of the small tower portion 8 with an external screw provided on the outer periphery. The lid base member 10 includes a disk-like base portion 32 having an engaging portion 31 that is a screw hole screwed into the locking portion 30. An annular leg 33 extending in a ring shape along the periphery of the base 32 protrudes on one surface of the base 32. The end surface of the annular leg 33 forms a flat placing surface 33S. Therefore, as shown in FIGS. 1 and 2, the device 1 can be held in an inverted state in which the bottom of the pressure-resistant bottle 2 faces upward by attaching the lid base member 10 with the placing surface 33 </ b> S facing outward. In this inverted state, the puncture sealant and high-pressure air are injected.

  Here, the lid base member 10 has an outer diameter Da (shown in FIG. 1) larger than the outer diameter Db (Da ≧ Db) of the pressure bottle 2 in order to stably hold the inverted state. It is preferable to set to. In order to prevent foreign matter from entering the high pressure air inlet 20 and the sealing agent outlet 25 and damage due to external force, the tip of the high pressure air inlet 20 and the tip of the sealing agent outlet 25 are provided with the pressure resistance. The outer peripheral surface of the bottle 2 and the outer peripheral surface of the lid base member 10 are preferably positioned radially inward. Even in such a case, since the lid base member 10 is detachable, removing the lid base member 10 obstructs the connection work of the hoses 5a and 4 to the high-pressure air intake 20 and the sealant outlet 25. However, connection work can be easily performed with good workability.

  In addition, as shown in FIG. 3, the main part of the apparatus 1 in the storage state is such that the outer diameter Dc of the small tower portion 8 is the outer diameter Db of the pressure-resistant bottle 2 and the outer diameter of the lid base member 10. Accordingly, a storage space H for winding and storing the feeding hose 4 around the small tower portion 8 can be formed. The feeding hose 4 is preferably wound and housed with one end attached to the sealant outlet 25 from the viewpoint of reducing the number of connection work steps and stowability. The air supply hose 5a is usually fixed at one end to a compressor that is a high-pressure air source 5, and therefore can be stored on the high-pressure air source side, and does not need to be wound around and stored in the storage space H. However, the air supply hose 5a can also be stored in the storage space H as required.

  In this storage state, the lid base member 10 is attached inward so that the placing surface 33S faces the pressure bottle 2. At this time, the annular leg 33 can hold the periphery of the feeding hose 4 wound around the storage space H, and thus can function as a rewinding prevention means 34 that suppresses the rewinding of the feeding hose 4. . In order to prevent rewinding, it can be achieved by pressing the winding end 4e of the feeding hose 4. That is, the annular leg portion 33 does not need to cover the storage space H around the entire length of the small tower portion 8, and the protruding height h of the annular leg portion 33 is 0 of the diameter d of the feeding hose 4. .5 times or more is sufficient. The upper limit of the protrusion height h is not particularly limited, but is preferably 1.0 times or less of the diameter d from the viewpoint of stability in an inverted state.

  Moreover, in the apparatus 1 of this embodiment, the sealant take-out unit 3 is stored on the vehicle with the pressure bottle 2 attached. Therefore, it is necessary to prevent the puncture sealing agent A in the pressure-resistant bottle 2 from flowing into the first and second flow paths 17 and 18 during on-vehicle storage. For this purpose, the cap 6 is fitted on the annular wall 7 and the air inlet 24 and the outlet 27 are covered and hermetically closed. In this example, a protruding plug body 6A that closes the outlet 27 is provided on the bottom surface 6S of the cap 6 to further improve the airtightness.

Next, the usage method of the apparatus 1 at the time of puncture repair is demonstrated with FIG.
First, as shown in (A), the apparatus 1 is stored on-board with the pressure-resistant bottle 2 attached to the sealant take-out unit 3. At this time, the supply hose 4 is wound around the small tower portion 8 and stored in the storage space H. The feed hose 4 is restrained from being unwound by the annular leg 33 of the lid base member 10 attached inward.

  At the puncture repair site, as shown in (B), the lid base member 10 is once removed from the small tower portion 8 and the air supply hose 5a of the high-pressure air source 5 is connected to the high-pressure air intake port 20 and the supply hose. 4 is rewound from the small tower 8. In this example, the feed hose 4 is stored on-board with one end of the supply hose 4 connected to the sealant outlet 25, but if not connected, it is connected at this time.

  Thereafter, as shown in (C), the lid base member 10 is attached again to the small tower portion 8 so that the annular leg portion 33 faces outward. The other end of the feeding hose 4 is connected to a tire air valve, and an electric plug of the high-pressure air source 5 is connected to a power source (a vehicle cigar socket or the like). Thereafter, as shown in (D), the apparatus 1 is inverted upside down, and the high pressure air source 5 is started in this inverted state.

  Here, when the high-pressure air source 5 is started, the cap 6 is first filled with high-pressure air. Then, the cap 6 is lifted by the increase of the internal pressure, and is automatically removed from the annular wall portion 7. As a result, the high-pressure air flows into the pressure-resistant bottle 2, and the puncture sealing agent A in the pressure-resistant bottle 2 passes through the outlet 27, the second flow path 18, the sealant outlet 25, and the supply hose 4 to the tire. Sent to T. Further, after the supply of the puncture sealing agent A, the high-pressure air continues to flow, and the tire T is automatically pumped up.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
