DETAILED DESCRIPTION

[0024] In order to help those skilled in the art to accurately understand the subject matter claimed in the present application, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0025] FIG. 1 is a schematic diagram of an embodiment of the sealant bottle according to the present application. For clear illustration, the bottle is drawn to be transparent so that its internal structure can be seen. The sealant bottle comprises a bottle body 1, which defines the inside of the bottle and provides an internal space 12 for storage of the sealant. The bottle body 1 has at least an inlet 16 and an outlet 18. As shown in the figure, the inlet 16 and the outlet 18 are respectively ports protruding outward from the top of the bottle, which can be connected with other objects such as tubes. The inlet 16 is used for passage of the gas, so it is a gas inlet. The gas inlet 16 is communicated with the internal space 12 at the inside of the bottle body, so that the gas can enter the internal space 12 through the gas inlet 16.

[0026] The bottle body 1 further has a pipe 22 inside it, which is used to receive the sealant. The pipe 22 defines a sealant delivery path and is communicated with the outlet 18, so that the sealant can be delivered to the outlet 18. Therefore, the outlet is a sealant outlet. The shape of the pipe 22 determines the sealant delivery path. As shown in the figure, the pipe 22 can be bent, and its beginning end is positioned against the wall 36 of the internal space 12. The beginning end of the pipe 22 is close to the bottom 34 of the bottle body 1, and is roughly between the bottom 34 of the bottle body 1 and the wall 36 of the internal space 12. The sealant can enter the pipe 22 from the bottom 34 of the bottle body 1. Specifically, it enters the pipe through the beginning end of the pipe 22. In the embodiment shown in the figure, a sealant receiver 24 is arranged at the beginning end of the pipe 22 to help more sealant to enter the pipe 22. The sealant receiver 24 can be a one-way valve, which only allows the sealant to enter the pipe 22 from the internal space 12, but does not allow reverse flow. The sealant receiver 24 can also be a positioning device to assist the beginning end of the pipe to position against the wall 36 of the internal space 12. These configurations help the sealant to enter the pipe 22. In addition, the shape of the sealant receiving part 24 is not limited to the form shown in the figure.

[0027] Further, the pipe 22 is provided with a gas lead-in part 26, which is on the sealant delivery path. The gas from the internal space 12 enters the pipe 22 through the gas lead-in part 26 and mixes with the sealant on the sealant delivery path.

[0028] Here, “on the sealant delivery path” can also be along the sealant delivery path. During the delivery of the sealant, the gas permeates, mixes with the sealant and flows to the outlet.

[0029] The arrangement of the gas lead-in part 26 provides the possibility of premixing the sealant. The gas is pumped into the bottle body 1, and a certain pressure is accumulated in the internal space 12, so that the air is pressed into the pipe 22 through the gas lead-in part 26. This manner of providing gas in an active manner not only increases the amount of air involved in mixing, but also omits additional pneumatic devices. In the embodiment shown in FIGS. 2-3, the double-line arrows represent the path of the gas, and the solid arrows represent the path of the sealant. When the sealant reaches the injection port of the tire, a second mixing will occur.

[0030] Referring again to FIG. 1, the bottle body 1 comprises a container 13 and a cover 14, which are connected in a sealed manner. The gas inlet 16 and the sealant outlet 18 are arranged on and integrated with the cover 14. The pipe 22 comprises at least one section inside the container 13 and another section inside the cover 14. The section of the pipe 22 inside the container 13 can be a pipe made of flexible material, such as a hose, so that the pipe 22 can be bent, while the another section is integrated with the cover 14. The gas lead-in part can be arranged on the hose as shown in FIG. 2, or on the cover as shown in FIG. 3. Although the gas lead-in part is not shown in the figures, it can be understood because of the flow of gas as shown. In these embodiments, the outer side of the pipe 22 can contact with gas to facilitate gas entry. The sealant can occupy at least part of the internal space 12. In general, the height of the gas lead-in part 26 in the bottle body 1 can be greater than the initial liquid level of the sealant, thus allowing only gas to enter the gas lead-in part 26, thereby achieving a better premixing effect.

[0031] Still further, the gas lead-in part 26 comprises at least one eyelet, which communicates with and between the internal space 12 and the interior of the pipe 22. There can be one eyelet, or there can be two eyelets as shown in FIGS. 2-3 (seen from FIGS. 2-3, although not shown, it can be seen that there are two eyelets according to the arrows indicating gas flow). When there is one eyelet, it is arranged on one circumferential side of the pipe. When there are two eyelets, they are respectively arranged on opposite circumferential sides of the pipe 22. It should be appreciated that there can also be more eyelets arranged around the pipe 22. When there are multiple eyelets, they can be arranged symmetrically or asymmetrically. The asymmetric arrangement can lead the gas into the pipe 22 in a balanced manner, because the sealant bottle is often inclined during use.

[0032] The eyelet has a gas-passage section, i.e., the size of the eyelet. The pipe 22 has a sealant-passage section, i.e., the cross section of the pipe 22. The size of the eyelet can be configured such that the ratio of the area of the sealant-passage section to the sum of the area of the gas-passage section is in the range of 8-89, preferably in the range of 32-89. Table 1 shows a plurality of sets of experimental data, where two eyelets are arranged. The gas-passage section of the eyelet depends on the diameter of the eyelet, which varies from 0 to 2 mm. When the size of the eyelet is 0, it can be considered that there is no gas lead-in part on the pipe 22. The size of the pipe 22 is unchanged along its entire length, with a diameter of 4 mm and an area of sealant-passage section of 12.57 mm.sup.2. It can be seen that when the ratio of the area of the sealant-passage section to the sum of the areas of the gas-passage sections is in the range of 8-89, the volume of the sealant after mixing will increase compared with the volume of the sealant before mixing. In particular, when the ratio of the above areas is in the range of 32-89, the volume of the sealant after mixing can increase to more than twice. This indicates that a large amount of sealant foam for tire repair is generated. It can also be seen that when the size of the eyelet is too large, the amount of sealant foam generated will be affected.

[0033] FIGS. 4-5 are the inside sectional views of the cover 14 of the sealant bottle. It can be seen that in the embodiment shown in FIG. 4, the pipe 22 is arranged in the center of the cover 14 and communicated with the sealant outlet 18. The pipe 22 is arranged along the longitudinal axis/of the cover, and the sealant outlet 18 is transverse to the longitudinal axis 1. The solid arrows show the flow of the sealant from the pipe to the sealant outlet, which is also the sealant delivery path. In the embodiment shown in FIG. 5, the gas inlet 16 extends inward to offset from the center of the cover 14 (the longitudinal axis 1 as shown in the figure) for a certain distance, thus communicating with the internal space 12. The internal space 12 surrounds the pipe 22 located in the center of the cover 14. The double-line arrows show the path of air. FIG. 5 shows an embodiment where the gas inlet 16 is integrated with the cover. The gas inlet 16 can also be integrated with the container 13, such as being arranged on the top of the container 13, so as to be communicated with the internal space 12.

[0034] When in use, the gas inlet 16 of the sealant bottle is connected to the air compressor through a tube. The sealant outlet 18 of the sealant bottle is connected with a feeding tube not shown. FIG. 1 shows a positioning part 32 for fixing the feeding tube. The feeding tube is connected to the valve core of the tire. The air compressor injects air into the sealant bottle, so at this time, there is a great pressure in the sealant bottle. The air compresses the sealant in the sealant bottle to force it to enter the pipe 22. At the same time, the air can enter the pipe 22 through the gas lead-in part 26, and mix with the sealant in the pipe 22 to form the sealant foam.

[0035] Although the specific embodiments of the present application have been illustrated and described in detail to explain the principle of the present application, it should be understood, however, that the present application can be implemented in other ways without departing from the principle.
