Description

Technical Field

[0001] The utility model relates to the technical field of vacuum devices, and more particularly to a Mason jar sealing device. Background Art

[0002] A Mason jar is a glass jar with excellent sealing properties. To effectively block the ingress of air and moisture and preserve the freshness of the food inside, a suitable Mason jar sealing device is usually used to completely extract the air from the jar, thereby extending the storage life of the food inside the jar. Mason jars are generally available in two calibers: standard and wide. Current Mason jar sealing devices are generally only suitable for Mason jars of one caliber. Multiple Mason jar sealing devices are required to meet the vacuuming needs of Mason jars of different calibers.

[0003] To address this issue, existing Chinese patent publication number CN216375472U discloses a Mason jar vacuum adapter. The adapter includes an adapter body with a partition disposed in the middle. The partition serves to separate the adapter body into a first housing and a second housing. The first housing has a first housing-shaped inner cavity, and the second housing has a second housing-shaped inner cavity. The openings of the first and second housings have different diameters. The partition is provided with a through hole connecting the first and second housings. The partition has an annular protrusion formed on either side of the first and second housings, corresponding to the through hole. The through hole interfaces with the exhaust pipe of a vacuum pumping device to facilitate vacuum extraction, and the annular protrusion acts as a seal. This type of Mason jar vacuum adapter has a body separated by a partition into a first housing and a second housing. The openings of the first and second housings have different diameters, allowing it to accommodate Mason jars with different mouth diameters.

[0004] However, in actual operation, the vacuum sealing of the Mason jar may fail. In this case, the position of the bottle cap needs to be readjusted or replaced with a new one. When vacuuming the Mason jar using a vacuum adapter similar to the above-mentioned Mason jar, the bottle cap used to seal the Mason jar will be directly stuck on the adapter body (i.e., the first cover-shaped inner cavity or the second cover-shaped inner cavity), making it difficult to pour out. The bottle cap needs to be pried out with the help of a tool. However, due to the size limitation of the bottle cap, it is still difficult to pry it out even with the help of a tool, and it may even be easy to injure the operator accidentally.

[0024] Example 1

[0025] like Figures 1 to 3 The first embodiment of the Mason jar sealing device of the present invention is shown. Figure 1 、 Figure 2 As shown, the Mason jar sealing device includes a main unit 1 and an adapter assembly 2. A partition plate 11 is provided in the main unit 1. One side of the partition plate 11 is a receiving chamber 12, and the other side is a sleeve 13. A vacuum pump 121 is provided in the receiving chamber 12. A through hole 111 is provided on the partition plate 11, and the through hole 111 is connected to the exhaust pipe (not shown) of the vacuum pump 121. Partition plate 11 is provided with a concentrically arranged outer bone 112 and inner bone 113 on one side of the sleeve 13, and the through hole 111 is located within the range enclosed by the inner bone 113. Figure 2As shown, the adapter assembly 2 includes a straight cylindrical bracket 21, both ends of which can be inserted and fixed in the sleeve 13. The two ends of the bracket 21 are respectively provided with a first opening 211 and a second opening 212. An annular partition 22 is also provided in the bracket 21. The first opening 211 and the second opening 212 are respectively located on both sides of the annular partition 22 and can both be installed at the bottle mouth of the Mason jar. In order to ensure the sealing of the adapter assembly 2 after being connected to the host 1, a first sealing structure is provided on the first opening 211, and a second sealing structure is provided on the second opening 212. When the first opening 211 is inserted into the sleeve 13, the first sealing structure surrounds the outer bone 112, and the second sealing structure fits with the outer thread of the bottle mouth of the Mason jar. At this time, the space above the bottle mouth is a closed sealed space. After turning on the vacuum pump 121, the gas in the Mason jar is extracted from the gaps around the bottle cap and is extracted by the vacuum pump 121 through the sealed space above the bottle mouth; similarly, when the second opening 212 is inserted into the sleeve 13, the second sealing structure surrounds the inner bone 113, and the first sealing structure fits with the outer thread of the bottle mouth of the Mason jar. At this time, the space above the bottle mouth is a closed sealed space. After turning on the vacuum pump 121, the gas in the Mason jar is extracted from the gaps around the bottle cap and is extracted by the vacuum pump 121 through the sealed space above the bottle mouth. Mason jars typically come in two sizes: large and small. The openings at either end of the cylindrical support 21 of the adapter assembly 2 accommodate the mouths of Mason jars of different calibers. Therefore, the Mason jar sealing device of this embodiment can seal and vacuum-evacuate Mason jars of varying calibers. Specifically, the sealing structures at both ends of the adapter assembly 2 of the present Mason jar sealing device not only seal the mouth of the Mason jar during vacuuming, but also form a sealed space with the sleeve 13 within the main body 1, thereby creating a pressure differential between the inside and outside of the jar to seal the Mason jar.

[0026] At the same time, due to the setting of the annular partition 22 in the straight cylindrical bracket 21 of the adapter assembly 2, when the bottle cap of the Mason jar is stuck in the adapter assembly 2 due to improper operation, it can be directly removed by hand from the bottle cap on the opposite side of the annular partition 22 without the aid of any tools, which is convenient and safe to use.

[0027] In order to ensure that the bottle mouth that is accidentally stuck in the adapter component 2 can be easily removed, Figure 2 and Figure 3 As shown, the size of the annular opening 221 in the middle of the annular partition 22 is slightly smaller than the size of the bottle cap used to seal the mouth of the Mason jar. In actual use, since the sealed space above the bottle cap can be connected to the vacuum pump 121 through the through hole 111 on the partition plate 11, the provision of the annular opening 221 will neither affect the extraction of gas from the Mason jar nor hinder the removal of the bottle cap that is accidentally stuck.

[0028] like Figure 2 and Figure 3As shown, a plurality of ribs 222 are evenly spaced on both sides of the annular partition 22. The ribs 222 are arranged in a divergent pattern from the center of the annular opening 221. In practice, when the annular partition 22 is closed over the mouth of the Mason jar, the ribs 222 act as a support and abut against the bottle cap, facilitating the extraction of gas from the bottle and creating a pressure differential with the sealed space above the bottle cap, thereby sealing the Mason jar.

[0029] Example 2

[0030] like Figures 1 to 4 The second embodiment of the Mason jar sealing device of the present invention is shown. Figure 4 As shown, the annular partition 22 of this embodiment is provided with a first support member 223 on one side of the first opening 211. The first sealing structure includes a first sealing ring 213, which is fixed to the first support member 223 and abuts against the inner wall of the first opening 211. When the first opening 211 is inserted into the sleeve 13, the first sealing ring 213 surrounds the peripheral bone 112. The partition plate 11, the peripheral bone 112, the first sealing ring 213, the first support member 223, and the annular partition 22 collectively form a first cavity 23, which is communicated with the annular opening 221. At this time, the second sealing structure abuts against the external thread of the Mason jar's mouth. In other words, this Mason jar sealing device is suitable for sealing Mason jars with small diameters. When the vacuum pump 121 is activated, the gas in the bottle overflows from around the bottle cap, passes through the top of the bottle cap, enters the first cavity 23 through the annular opening 221 of the annular partition 22, and is then pumped out by the vacuum pump 121 through the through hole 111 in the partition plate 11. It is understood that in order to achieve a better sealing effect, the first sealing ring 213 can be configured as a sealing ring with a groove.

[0031] Example 3

[0032] like Figures 1 to 4 The third embodiment of the Mason jar sealing device of the present invention is shown. Figure 5As shown, the annular partition 22 of this embodiment is provided with a second support member 224 on one side of the second opening 212. A mounting groove 225 is formed between the second support member 224 and the inner wall of the bracket 21. The second sealing structure includes a pressure-maintaining member 214 and a second sealing ring 215. The pressure-maintaining member 214 is disposed within the mounting groove 225 and abuts against the inner wall of the second opening 212. The second sealing ring 215 is fixed to the inner wall of the pressure-maintaining member 214. When the second opening 212 is inserted into the sleeve 13, the second sealing ring 215 surrounds the inner peripheral rib 113. The partition plate 11, the inner peripheral rib 113, the second sealing ring 215, the second support member 224, and the annular partition 22 collectively form a second cavity 24, which is connected to the annular opening 221. At this time, the first sealing structure abuts against the external thread of the Mason jar's mouth. In other words, this Mason jar sealing device is suitable for sealing Mason jars of large diameters. Different from the second embodiment, when sealing the mouth of a large-diameter Mason jar, the second opening 212 of the bracket 21 needs to maintain the stability and sealing of the entire straight cylindrical bracket 21 when it is connected to the sleeve 13, so a pressure-maintaining member 214 is required to fix the second sealing ring 215.

[0033] like Figure 6 As shown, the pressure-maintaining member 214 includes a housing 216 and a step 217 disposed on the inner side of the housing 216. The second sealing ring 215 is provided with a groove 218, and a sealing strip 219 extends outward from the bottom of the groove 218. The second sealing ring 215 is disposed on the step 217. One side of the groove 218 is in contact with the inner side of the housing 216, and the other side surrounds the inner peripheral frame 113. The sealing strip is in contact with the inner side of the step 217 and then embedded in the mounting groove 225. When the vacuum pump 121 is activated, the gas in the bottle overflows from around the bottle cap, passes through the top of the bottle cap, and enters the second cavity 24 through the annular opening 221 of the annular partition 22. The gas is then drawn out by the vacuum pump 121 through the through hole 111 in the partition plate 11.

[0034] In the above embodiment, for the convenience of practical use, the axial length of the straight cylindrical bracket 21 is greater than the depth of the insertion into the sleeve 13, so that the user is more convenient when holding the adapter component 2, and it is also easier to install and fix. In addition, there are many ways to connect the adapter component 2 to the host 1. In the embodiment of the utility model, the two are fixed by a socket-type clamping method. Specifically, Figure 1 and Figure 3 As shown, a guide stopper 131 is provided on the inner wall of the sleeve 13, and a mounting rail 251 is provided on the outer wall of the bracket 21. The bracket 21 is fixedly inserted into the sleeve 13 through the cooperation between the mounting rail 251 and the guide stopper 131. At the same time, since the two ends of the adapter assembly 2 are respectively adapted to Mason jars of different diameters, the mounting rails 251 on the outer wall of the bracket 21 should be arranged in a centrally symmetrical manner, that is, as shown in FIG. Figure 3As shown, the mounting rail 251 is provided with an entrance 252 on the outer wall at both ends of the bracket 21, and a bend 253 is provided in the middle of the mounting rail 251. When the bracket 21 is inserted into the sleeve 13, the guide limiter 131 slides along the entrance and rotates to the bend 253 to be fixed.

[0035] The Mason jar sealing device of the present invention is provided with an adapter assembly 2, which includes a straight cylindrical bracket 21 with both ends of which can be plugged and fixed on the sleeve 13 of the main body 1, and an annular partition 22 is provided in the bracket 21. Openings are respectively provided at both ends of the bracket 21, and the openings are arranged on both sides of the annular partition 22. The openings at both ends are provided with sealing structures, which can be sealed with the sleeve 13. Since both ends of the adapter assembly 2 can be installed at the bottle mouth of the Mason jar, and the part connected with the main body 1 can form a sealed space, it is possible to seal and vacuum Mason jars of different calibers; at the same time, due to the setting of the annular partition 22 in the straight cylindrical bracket 21 of the adapter assembly 2, when the bottle cap of the Mason jar is stuck in the adapter assembly 2 due to improper operation, it can be directly removed by hand from the bottle cap on the opposite side of the annular partition 22 without the aid of any tools, and it is convenient and safe to use.

[0036] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
