AI Technical Summary
[0016] This application allows for the mixing of sealant and gas within the sealant bottle. The mixing of sealant and gas occurs through a gas inlet. It has been found that this pre-emptive and proactive mixing significantly increases the volume of the sealant compared to mixing at the tire or otherwise. For example, mixing sealant with surrounding air at the tire can increase its volume by 30-40%. Furthermore, mixing by shaking the sealant bottle or by introducing air into the sealant through the bottle's internal channels can increase its volume by less than 10%. This application, however, can increase the volume by more than 100%. Therefore, the sealant bottle of this application ensures that the sealant has already formed a foamy form and is present in considerable quantity when it reaches the tire's injection port (typically the valve core). This, in turn, reduces the amount of sealant used and improves tire repair efficiency.

Abstract
Description
[0001] This application is a divisional application of Chinese patent application filed on July 9, 2020, with application number 202010656035.6 and invention title "Sealing Agent Bottle". Technical Field
[0002] This application relates to the field of automotive maintenance tools, and more specifically to a sealant bottle. Background Technology
[0003] During vehicle operation, tires may experience abnormal conditions, such as low pressure or punctures. In such cases, a spare tire is typically used to replace the low-pressure or damaged tire, or a tire repair and inflation service is used.
[0004] There is now a type of pneumatic tire used on vehicles. When a tire is punctured, it does not need to be replaced; instead, a sealant is injected into the tire to repair the puncture.
[0005] Sealant is a polymer compound, normally liquid, and stored in a sealant bottle. During the tire repair process described above, air is first pumped into the sealant bottle, causing the sealant to be pumped out and then into the tire. As the sealant enters the tire, it collides with and mixes with the surrounding air, increasing in volume and forming a foam. This foamed sealant then enters the tire, reaching the puncture site and covering the inner tire wall to form a sealing film. Ideally, less sealant should be used to repair the tire.
[0006] JP4666613B2 discloses a sealant injection device, including a reservoir for storing sealant and a mixing section outside the reservoir. Air enters the reservoir and the mixing section through two branch pipes, respectively. The air entering the reservoir forces the sealant into the mixing section, where it mixes with the air entering directly into the mixing section. The mixed sealant is then output to the tire and injected into the tire via the tire valve core. A valve is provided at the beginning of the branching of the two pipes to distribute the airflow to each branch pipe. For this purpose, the injection device according to JP4666613B2 is also provided with a controller for manual or automatic control. Summary of the Invention
[0007] One aspect of this application relates to a sealant bottle comprising a bottle body defining an internal space for storing sealant, and having: a gas inlet in fluid communication with the internal space to allow gas to enter the internal space; a conduit for receiving sealant, at least a portion of the conduit being disposed in the internal space; and a sealant outlet communicating with the conduit; wherein the conduit defines a sealant delivery path leading to the sealant outlet, the conduit further comprising a gas inlet on the sealant delivery path, the gas inlet being configured such that gas enters from the internal space via the gas inlet into the conduit to mix with the sealant on the sealant delivery path.
[0008] In one embodiment of a sealant bottle, the bottle body includes a container and a cap that is sealed to the container, and the gas inlet is disposed on a portion of the conduit located inside the container and / or on another portion of the conduit located on the cap.
[0009] In one embodiment of a sealant bottle, the gas inlet includes at least one aperture disposed on the conduit communicating between the internal space and the interior of the conduit.
[0010] In one embodiment of a sealant bottle, the conduit has a sealant passage section, the at least one orifice has a gas passage section, and the ratio of the area of the sealant passage section to the sum of the areas of the gas passage sections of the at least one orifice is in the range of 8-89.
[0011] In one embodiment of a sealant bottle, the ratio of the area of the sealant through the cross section to the sum of the areas of the gas through the at least one orifice is in the range of 32-89.
[0012] In one embodiment of a sealant bottle, when the at least one orifice includes a single orifice, the single orifice is arranged on one circumferential side of the conduit; when the at least one orifice includes two orifices, the two orifices are respectively arranged on opposite circumferential sides of the conduit; and when the at least one orifice includes more orifices, the more orifices are arranged around the conduit.
[0013] In one embodiment of a sealant bottle, the gas inlet and the sealant outlet are arranged on the cap, or the gas inlet is arranged on the container and the sealant outlet is arranged on the cap.
[0014] In one embodiment of a sealant bottle, the portion of the conduit within the container is a tube made of a flexible material, and the tube has a sealant receiving portion at the bottom of the bottle body to allow sealant to enter the tube from the bottom.
[0015] In one embodiment of a sealant bottle, a throat tube is also included outside the bottle body, the throat tube being connected to the sealant outlet.
[0016] This application allows for the mixing of sealant and gas within the sealant bottle. The mixing of sealant and gas occurs through a gas inlet. It has been found that this pre-emptive and proactive mixing significantly increases the volume of the sealant compared to mixing at the tire or otherwise. For example, mixing sealant with surrounding air at the tire can increase its volume by 30-40%. Furthermore, mixing by shaking the sealant bottle or by introducing air into the sealant through the bottle's internal channels can increase its volume by less than 10%. This application, however, can increase the volume by more than 100%. Therefore, the sealant bottle of this application ensures that the sealant has already formed a foamy form and is present in considerable quantity when it reaches the tire's injection port (typically the valve core). This, in turn, reduces the amount of sealant used and improves tire repair efficiency.
[0017] This application features a simple and reliable structure. After the gas is pumped into the sealant bottle, the high-pressure gas inside the bottle can both push the sealant into the pipeline and enter the pipeline through the gas inlet to mix with the sealant during the transportation process. Because the mixing occurs within the pipeline, there is no need for additional pneumatic devices inside the sealant bottle, no need for a separate mixing component, and no need for a separate pressure control component. Therefore, this application has the advantages of low cost and ease of manufacture.

However, it should be understood that the drawings are designed for illustrative purposes only and are not intended to limit the scope of this application, as reference should be made to the appended claims. It should also be understood that the drawings are intended only to conceptually illustrate the structures and processes described herein, and are not necessarily drawn to scale unless otherwise indicated.

Wherein: Figure 1 This is a schematic diagram of one embodiment of the sealant bottle involved in this application; Figure 2 This is a schematic diagram of the sealant bottle involved in this application after the container has been removed; Figure 3 This is a schematic diagram of one embodiment of the cap of the sealant bottle involved in this application; Figure 4 This is a cross-sectional view showing the opening of the sealant bottle involved in this application; Figure 5 This is a cross-sectional view showing the inlet of the sealant bottle involved in this application. Detailed Implementation
[0020] To help those skilled in the art to accurately understand the subject matter claimed in this application, the specific embodiments of this application are described in detail below with reference to the accompanying drawings.
[0021] Figure 1 This is a schematic diagram of one embodiment of the sealant bottle involved in this application. For clarity, the bottle is shown transparently, revealing its internal structure. The sealant bottle includes a bottle body 1 that defines the interior of the bottle and provides an internal space 12 for storing the sealant. The bottle body 1 has at least an inlet 16 and an outlet 18. As shown, the inlet 16 and outlet 18 are respectively ports projecting outward from the top of the bottle, which can be connected to other objects such as pipes. The inlet 16 is for the passage of gas and is therefore a gas inlet. The gas inlet 16 communicates with the internal space 12 inside the bottle body, thereby allowing gas to enter the internal space 12 via the gas inlet 16.
[0022] The bottle body 1 also has a conduit 22 inside. The conduit 22 is used to receive sealant. The conduit 22 defines a sealant delivery path and communicates with an outlet 18, whereby the sealant can be delivered. Therefore, the outlet is the sealant outlet. The shape of the conduit 22 determines the sealant delivery path. As shown, the conduit 22 can be curved and its initial end is positioned against the wall 36 of the internal space 12. The initial end of the conduit 22 is close to the bottom 24 of the bottle body 1, approximately between the bottom 34 of the bottle body 1 and the wall 36 of the internal space 12. The sealant can enter the conduit 22 from the bottom 34 of the bottle body 1. Specifically, it enters the conduit via its initial end. In the embodiment shown, a sealant receiving section 24 is provided at the initial end of the conduit 22 to facilitate more sealant entering the conduit 22. The sealant receiving section 24 can be a one-way valve, allowing the sealant to enter the conduit 22 only from the internal space 12 and not flow in the reverse direction. The sealant receiving section 24 can also be a positioning device to assist in positioning the beginning of the pipe against the wall 36 of the internal space 12. These arrangements all facilitate the entry of sealant into the pipe 22. Furthermore, the shape of the sealant receiving section 24 is not limited to the form shown in the figures.
[0023] Furthermore, a gas inlet 26 is provided on the pipe 22, which is located on the sealant delivery path. Gas from the internal space 12 enters the pipe 22 via the gas inlet 26 and mixes with the sealant on the sealant delivery path.
[0024] Here, "on the sealant delivery path" can also mean along the sealant delivery path. During the sealant delivery process, gas seeps in, mixes with the sealant, and flows towards the outlet.
[0025] The gas inlet 26 provides the possibility of premixing the sealant. Gas is pumped into the bottle body 1, and pressure builds up in the internal space 12, thus forcing air into the pipe 22 via the gas inlet 26. This active gas supply method increases the amount of air involved in mixing while eliminating the need for additional pneumatic mechanisms. Figure 2-3 In the illustrated embodiment, double-lined arrows represent the path of the gas. Solid-lined arrows represent the path of the sealant. A second mixing occurs when the sealant reaches the tire's injection port.
[0026] Back Figure 1 The bottle body 1 includes a container 13 and a cap 14, which are sealed together. A gas inlet 16 and a sealant outlet 18 are provided and integrated into the cap 14. A conduit 22 includes at least a portion within the container 13 and another portion on the cap 14. The portion of the conduit 22 within the container 13 may be a tube made of a flexible material, such as a hose, allowing it to bend, while the other portion is integrated with the cap 14. The gas inlet may be, for example, a... Figure 2 The setting shown is on the hose, or it can be as follows: Figure 3 The arrangement shown is on the cap. Although the gas inlets are not shown in the figure, they can be understood through the flow of gas. In these places, the outside of the pipe 22 can contact the gas to facilitate gas entry. The sealant can occupy at least part of the internal space 12. Generally, the height of the gas inlet 26 within the bottle body 1 can be greater than the initial liquid level of the sealant, thus allowing only gas to enter the gas inlet 26 and achieving a better premixing effect.
[0027] Furthermore, the gas inlet 26 includes at least one aperture that communicates between the interior space 12 and the interior of the pipe 22. It can be a single aperture or... Figure 2-3 The two holes shown (as shown) Figure 2-3 As shown (although not explicitly shown, the arrows indicating gas flow suggest there are two orifices), when there is one orifice, it is arranged on one circumferential side of the pipe. When there are two orifices, they are arranged on opposite circumferential sides of pipe 22. It should be understood that there can also be more or fewer orifices arranged around pipe 22. When there are multiple orifices, they can be arranged symmetrically or asymmetrically. An asymmetrical arrangement can guide the gas into pipe 22 in a balanced manner, since the sealant bottle is often placed at an angle during use.
[0028] The orifice has a gas passage cross-section, as shown in the orifice size. The pipe 22 has a sealant passage cross-section, as shown in the cross-section of the pipe 22. The orifice size can be set such that the ratio of the area of the sealant passage cross-section to the total area of the gas passage cross-section is in the range of 8-89, preferably in the range of 32-89. Table 1 shows multiple sets of experimental data, with two orifices. The gas passage cross-section of the orifice depends on the orifice diameter, which varies from 0 to 2 mm. When the orifice size is 0, it can be considered that no gas inlet is provided on the pipe 22. Even if the dimensions of the pipe 22 remain constant along its entire length, with a diameter of 4 mm, the area of its sealant passage cross-section is 12.57 mm². 2 As can be seen, when the ratio of the area of the sealant passage cross-section to the total area of the gas passage cross-section is between 8 and 89, the volume of the mixed sealant increases compared to the unmixed sealant. Particularly when the area ratio is within the range of 32-89, the mixed volume can more than double. This indicates the generation of a large amount of sealant foam for tire repair. It can also be seen that excessively large pore sizes affect the amount of sealant foam generated.

[0029] Table 1 Figure 4 and Figure 5 This is a cross-sectional view of the inner side of the cap 14 of the sealant bottle. It can be seen that... Figure 4 In the illustrated embodiment, conduit 22 is located at the center of cap 14 and communicates with sealant outlet 18. Conduit 22 runs along the longitudinal axis of the cap. l The sealant outlet 18 is positioned transversely to the longitudinal axis. l The solid arrows indicate the flow of sealant from the pipe to the sealant outlet, which is also the sealant delivery path. Figure 5 In the illustrated embodiment, the gas inlet 16 extends inward to the center of the bias cap 14 (as shown by the longitudinal axis in the figure). l A distance is provided to connect with the interior space 12, which surrounds the pipe 22 located at the center of the cover 14. Double-lined arrows indicate the path of the air. Figure 5 An embodiment is shown in which the gas inlet 16 is integrated with the cover. The gas inlet 16 can also be integrated with the container 13, such as being located on the top of the container 13, thereby communicating with the internal space 12.
[0030] In use, the gas inlet 16 of the sealant bottle is connected to an air compressor via a pipe. The sealant outlet 18 of the sealant bottle is connected to a hose (not shown). Figure 1The positioning part 32 for fixing the throat is shown. The throat is connected to the valve core of the tire. The air compressor pumps air into the sealant bottle, at which time the sealant bottle is under high pressure. The air compresses the sealant in the sealant bottle and forces it into the pipe 22. At the same time, the air can enter the pipe 22 through the gas inlet 26 and mix with the sealant in the pipe 22 to form sealant foam.
[0031] Although specific embodiments of this application have been shown and described in detail to illustrate the principles of this application, it should be understood that this application may be implemented in other ways without departing from such principles.
