Description

Technical field

[0001] The present invention relates to a container for a tire puncture repair kit and in particular to a container for a tire puncture repair kit which improves storage capability on board and is able to prevent damage during storage. State of the art

[0002] For several years now, when a tire on a vehicle is punctured, tire repair fluid has been injected into the tire through the valve to temporarily repair the puncture. A tire puncture repair kit is used as a device that enables such a temporary repair. Using a tire puncture repair kit eliminates the need to carry a spare tire, thus saving resources and reducing vehicle weight. Another advantage is that the space freed up by a spare tire in the vehicle can be used for other purposes.

[0003] A well-known tire repair kit includes, for example, a so-called pump-type tire repair kit, which injects tire repair fluid contained in a reservoir into a tire using compressed air supplied by an air compressor or similar device (see, for example, JP 2013-220622 A). The reservoir used in such a pump-type tire repair kit typically includes a reservoir housing with a receiving section for the tire repair fluid, an opening section, and a cap mounted on the opening section of the reservoir housing. Furthermore, in some cases, a hose for connecting the reservoir (cap) to a compressor is pre-attached.

[0004] In the case of a tire repair kit of this type, where the inner tube is pre-attached, one end of the tube is detached. This makes storage on board difficult, and there is a risk that any load exerted on the tube itself or on the connecting section of the tube to the cap will cause damage. In particular, research has been conducted in recent years to reduce the length of the inner tube in order to further reduce the weight and cost of the tire repair kit. However, reducing the tube length makes it difficult to store the tube by routing it along the outer circumference of the container, and the effects of this become more pronounced with increasing load. Therefore, a countermeasure has been requested.

[0005] EP 2 497 629 A1 discloses a breakdown repair kit in which a bottle unit is arranged. The breakdown repair kit comprises a compressor device and a bottle unit in which a cap is attached to an opening of a bottle container holding a puncture sealant. The cap includes an opening to which a hose is connected. The hose can be wound around the cap.

[0006] JP 2007 - 144 876 A discloses a container for sealing fluid with a cap that includes a storage compartment for winding and storing a supply hose around a small tower section. The supply hose is wound and housed in the storage compartment, with one end connected to the sealant outlet.

[0007] US 2009 / 0 107 578 A1 discloses a tire sealing device comprising a container assembly with a container having a cap. The cap includes an outlet opening for connecting a hose. The outlet hose is held in a coiled configuration by tension. The hose has a kink that seals the hose.

[0008] DE 103 36 959 A1 discloses a device for filling a pneumatic tire with a sealant from a sealant container, which has a coupling device for connecting the container to a receiving device. The receiving device has a nozzle and a pipe connected thereto. Brief description of the invention: Technical problem

[0009] One object of the present invention is to provide a container for a tire puncture repair kit, in particular a container for a tire puncture repair kit that improves storage on board and is able to prevent damage during storage. Solution to the problem

[0010] To fulfill the aforementioned objective, a container for a tire puncture repair kit was created, which has the features of independent claim 1. An advantageous embodiment is described in dependent claim 2. Advantageous effects of the invention

[0011] In one embodiment of the present invention, the engagement section is provided in the closure as described above. Thus, even if the hose is pre-connected to the container (closure), the hose can be engaged by causing it to extend along the circumference of the closure when not in use. This improves storability and, moreover, because the ends of the hose are not detached, prevents damage to the hose during storage.

[0012] In one embodiment, the hose can be connected to the connection section on one side of an outlet channel for dispensing the tire puncture repair fluid to the outside of the container in the receiving section, and can have a length of 50 mm to 150 mm. Even from this perspective, since the engagement section is provided as described above, the hose can be brought into engagement by causing it to extend along the circumference of the closure when not in use. In particular, even if the hose is of a short length, as described above, the engagement section is present on the outer surface of the closure, and thus the hose reliably reaches the engagement section and can be brought into engagement appropriately.As a result, the storage capacity of the container can be improved, and furthermore, since the ends of the hose are not detached, damage to the hose during storage can be suppressed.

[0013] According to the present invention, a flange section with a flat, plate-like shape and an outer diameter larger than the outer diameter of other sections of the closure is provided in an upper surface of the closure, and the engagement section is arranged in a surface on the container housing side of the flange section. The flange section and the engagement section are provided as described above, and thus, during storage, the hose is stored in a recessed section formed by the flange section, a closure-side surface, and the container housing, thereby improving the storage capacity of the container as a whole. Furthermore, in this case, the hose is stored in the recessed section and protected by the flange section and the container housing, thus effectively preventing damage to the hose.Furthermore, the outer diameter of the closure increases, thus making it easier to mount the closure onto the container housing.

[0014] The flange section, when viewed from one side of the upper surface of the closure, has a fan-like shape, and the connecting section and the flange section are separated by a gap of 15 mm to 30 mm. Because the flange section has a fan-like shape, as described above, it projects into the vicinity of both ends of the connecting section, and this projecting section can more effectively protect the connecting section. Meanwhile, the appropriate gap between the connecting section and the flange section is ensured, and thus good manufacturability can be adequately maintained when connecting the hose to the connecting section.

[0015] In one embodiment of the present invention, the closure preferably includes a valve insert pressure section, and the valve insert pressure section has a shape capable of entering a tube with an inner diameter of 5 mm over a distance of 0.5 mm or more. The valve insert pressure section is provided as described above, and thus, if excessive air is injected into a tire during puncture repair work, air can be released by pressing a distal end of a valve insert with the valve insert pressure section.

[0016] Configurations of embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] As in Fig. 1 and Fig. As illustrated in Figure 2, a container of a tire puncture repair kit 1 (hereinafter referred to as "container 1") according to one embodiment of the present invention includes a container housing 10, a closure 20, and a hose 30. In one embodiment of the present invention, as described below, the container 1 of such a type, in which at least one hose 30 is pre-mounted on the closure 20, is provided with an engagement section 40 in an outer surface of the closure 20, and the engagement section 40 engages the hose 30 in an unused state by causing the hose to extend over a circumference of the closure. Thus, the internal structures of the container housing 10 and the closure 20 are not particularly restricted, and a structure generally used as a tire puncture repair kit (container 1) can be employed.

[0018] It should be noted that one embodiment of the present invention can be suitably incorporated into a tire repair kit (container 1) of such a type that the length of the hose 30 is fixed to, for example, 50 mm to 150 mm to reduce weight, and that the container housing 10 and the closure 20 are used in a suspended position from a tire valve via the hose 30. That is to say, in the tire repair kit (container 1) of this type, the hose 30 is short, and thus, unlike a long hose, the hose 30 cannot be held and stored by a method in which, for example, the hose is caused to extend along and wrap around the container housing 10 or the circumference of the closure 20. The hose can be stored compactly by engaging it via the engagement section 40 described below.

[0019] As in the Fig. 1 and Fig. As illustrated in Figure 2, the container housing 10 includes a receiving section 11, which has a cylindrical shape and receives tire puncture repair fluid (hereinafter referred to as "repair fluid"), including, for example, rubber latex, and an opening section 12, which has a cylindrical shape and is located on an upper section side of the receiving section 11 when the container housing 10 is upright, and which dispenses the repair fluid during use. When the container 10 is upright, a bottom surface of the receiving section 11 is located on a side opposite the opening section 12. Although omitted in the drawings, preferably an outer circumferential surface of the opening section 12 includes threads that engage with a screw described below on the side of the closure 20.The receiving section 11 and the opening section 12 are manufactured in one piece from, for example, a synthetic resin such as polypropylene and polyethylene. It should be noted that the opening section 12 can be welded more tightly with, for example, a coating (not illustrated) before the closure 20 described below is fitted, in order to prevent deterioration of the repair fluid in the container and leakage of the repair fluid from the opening section 12.

[0020] As in the Fig. 1, Fig. 2 to Fig. As illustrated in Figure 3, the closure 20 includes a cover section 21, which closes the opening section 12, and a mounting section 22, which has a cylindrical shape and can be mounted on the opening section 12. As described above, if the outer circumferential surface of the opening section 12 is threaded, an inner circumferential surface of the mounting section 22 can also be threaded, engaging with a screw on the side of the opening section 12, thus providing threaded engagement with the container housing 10 (opening section 12) and the closure 20 (mounting section 22). The cover section 21 and the mounting section 22 are manufactured in one piece from, for example, a synthetic resin such as polypropylene and polyethylene.The lid section 21 is provided with an inlet channel 23 for introducing compressed air from the outside of the container and an outlet channel 24 for dispensing the tire puncture repair fluid into the container as holes penetrating the lid section 21. At one end on the outside of the container, a connection section 25 is provided for connecting the hose 30. In the illustrated example, the connection section 25 projects radially outside the closure 20, and the connection section 25 on the side of the outlet channel 24 is inserted into the hose 30. Additionally, a flange section 26 is formed at a position on an upper surface of the closure 20 (lid section 21), projecting radially outside with respect to the mounting section 22.In the illustrated example, the engagement section 40 is provided in a lower surface of the flange section 26 (surface on the side of the container housing 10).

[0021] The hose 30 is pre-assembled on the connecting section 25 of the closure 20 and connects the container 1 to a compressor or a tire. In the illustrated example, as described above, the hose 30, as part of the container 1, is only pre-assembled on the connecting section 25 on the side of the outlet channel 24. The material of the hose 30 is not particularly limited. With regard to pressure resistance, which can withstand the pressure of compressed air supplied from a compressor, suitable flexibility, which allows for easy handling when repairing punctures, and the suppression of degradation caused by long-term storage on board, synthetic rubber such as EPDM is preferably used. In the illustrated example, when the puncture repair kit is used, a detached end of the hose 30 is connected to a tire valve.It should be noted that in the illustrated example, a hose (not illustrated) is additionally connected to the connection section 25 on the side of the inlet channel 23 when the tire repair kit is used. The hose (not illustrated) then connects a compressor (not illustrated) and the container 1 (inlet channel 23).

[0022] In the illustrated example, the container 1 encloses a hose H internally, and the hose H encloses one end connected to the closure 20 and the other end extending to a lower section of the container housing 10. The hose H allows the discharge channel 24 to extend substantially to the bottom of the receiving section 11 to reliably dispense the tire puncture repair fluid. The structure of the hose H is not particularly limited in one embodiment of the present invention, and thus a detailed description of the hose H is omitted.

[0023] The shape of the engagement section 40 is not particularly restricted as long as the hose 30 can be engaged. For example, in the illustrated example, an engagement section including a pair of projections spaced at such a distance that the hose can be positioned between them is used. In this case, as shown in Fig. Figure 4 illustrates how the hose 30 is positioned between the projections, allowing it to engage. Furthermore, when the tire repair kit is used, the hose 30 is pulled out of a space between the projections and can be easily removed. In such an engagement section 40, the distance between the projections is preferably set to 70% to 80% of the outer diameter of the hose 30. That is, if the distance between the projections is set to be slightly smaller than the outer diameter of the hose 30, the hose 30, positioned between the projections, deforms appropriately and engages in this state. Thus, the hose 30 can be reliably engaged.

[0024] With regard to durability and the like, the engagement section 40 is preferably cast integrally with the closure 20. However, the engagement section 40 can be attached to the closure 20 as a separate component. In a case where the engagement section 40 is attached subsequently, an advantage is that the engagement section 40 can optionally be attached to the closure 20, which has an existing general structure.

[0025] As in the example that is in the Fig. 1, Fig. 2, Fig. 3 to Fig. As illustrated in Figure 4, the engagement section 40, as described above, is located on the lower surface of the flange section 26. The flange section 26 is a section having a flat, plate-like shape and projects radially outward from the upper surface of the closure 20 (lid section 21), with an outer diameter larger than the outer diameter of other sections of the closure 20, as described above. Thus, the side surface of the closure 20 (in particular, the mounting section 22) is recessed with respect to the flange section 26 and a side surface of the container housing 10, and the hose can be stored in the recessed section. As a result, the storage capacity of the container 1 as a whole can be improved.It should be noted that in a case where the flange section 26 is provided, the maximum diameter of the closure 20 increases, and thus the torque generated when the closure 20 engages in threaded engagement with the container housing 10 can be increased, and the assembly of the closure 20 can be facilitated. It can also be, as in . Fig. Figure 5 illustrates an embodiment not according to the invention, in which the engagement section 40 described above, which is formed from the pair of projections, is also provided in the side surface of the closure 20, which has a column-like shape and an existing structure, without providing the flange section 26.

[0026] Preferably, the outer diameter of the flange section 26 is equivalent to the outer diameter of the receiving section 11 of the container housing 10. According to the invention, the outer diameter of the flange section 26 is 80% to 110% of the outer diameter of the receiving section 11 of the container housing 10. The size of the flange section 26 is determined as described above, and thus the storage capacity of the container 1 as a whole can be improved. With regard to the storage capacity of the container 1 as a whole, it is more preferably the outer diameter of the flange section 26 that is smaller than the outer diameter of the receiving section 11 of the container housing 10.

[0027] The shape of the flange section 26 (the shape when viewed from the side of the upper surface of the closure 20) is not particularly restricted, and, for example, a rectangular shape with rounded corners, as in Fig. Figure 6 illustrates how it can be used. In this example, the engagement section 40 (indicated by the dashed line in the figure) is provided in a section that projects outwards from the body part of the closure 20. As shown in Fig. As illustrated in Figure 3, a pair of fan-like shapes are preferably arranged in an axially symmetrical manner with respect to the opposite pair of connecting sections 25. In other words, a circular shape from which the surroundings of the connecting section 25 are cut out is preferred. According to such a shape, in comparison to the rectangular shape with rounded corners of Fig. 6. The section projecting outwards towards the side of the connecting section 25 protects the connecting section 25 itself and a section of the hose 30 connected to the connecting section 25. Since the flange section 26 is installed with such a fan-like shape, the separation distance between the connecting section and the flange section is 15 mm to 30 mm. A suitable separation distance between the connecting section 25 and the flange section 26 is ensured as described above, and thus good workability can be sufficiently maintained at the time of connecting the hose 30 to the connecting section 25.It should be noted that “fan-like shape” refers to a shape obtained by connecting a pair of concentric arcs with radial lines, and also includes a shape where sections connecting the arcs are not linear, as on the side of the outflow channel 24 of the flange section 26 of . Fig. 7. On a side to which the hose 30 is pre-connected, no work is carried out to connect the hose 30 except at the time of manufacture. Thus, in the flange section 26 of Fig. 7 an edge section of the flange section 26 along the direction of travel of the connecting section 25 to improve the protective performance.

[0028] According to the structure described above, the hose 30 can be engaged, and the storage capacity of the container 1 can be improved. Furthermore, valve insert pressure sections 41 can be provided in the closure 20 as an additional element. That is to say, in recent years, a function capable of releasing air when excessive air is injected into a tire has, in some cases, been omitted from a tire repair kit from a compressor main body to further reduce its weight. Therefore, a structure capable of releasing air by pressing a distal end of a valve insert is preferably added to the closure 20 to ensure good performance of a tire repair kit.In particular, the valve insert pressure sections 41 are preferably provided, each having a shape capable of entering a pipe with an inner diameter of 5 mm over a distance of 0.5 mm or more to 1.5 mm or less. Fig. 8A to 8C are the valve insert pressure sections 41, each having the shape described above, provided as projections extending from the outer surface of the closure 20. In particular, in Fig. 8A the valve insert pressure sections 41 are provided in corner sections of the flange section 26. In Fig. 8B the valve insert pressure sections 41 are provided in arc sections of the flange section 26. In Fig. In 8C, the valve insert pressure sections 41 are provided in an upper surface of the flange section 26. It should be noted that even if the valve insert pressure sections 41 are provided in the upper surface of the flange section 26, as in Fig. Figure 8C illustrates that the valve insert pressure sections 41 are small projections sufficient to press the distal end of the valve insert as described above, and thus the storage capacity of the container 1 as a whole is not affected. Furthermore, in Fig.9. The diameter of the lower surface of the flange section 26 is larger than the diameter of the upper surface of the flange section 26, and an edge of the upper surface and an edge of the lower surface of the flange section 26 are coupled to a side surface having an arc cross-section. Thus, a section of the flange section 26, enclosed by the dashed line in the figure (the section where the linear line section connecting the concentric circle and the outer arc section in the fan-shaped flange section 26 are coupled), is pointed at an acute angle. The pointed section has a shape capable of entering the 5 mm inner diameter tube over a distance of 0.5 mm or more, and thus this section functions as the valve insert pressure section 41.In both the case where the valve insert pressure sections 41 are provided as projections and the case where the flange section 26 itself functions as the valve insert pressure sections 41, the distal ends of the valve insert pressure sections 41 preferably each have a surface for easy pressing of the distal end of the valve insert.
