Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, and particularly relates to a water-retaining sealing cover, a pickling jar and a method for self-adaptive flexible sealing and protection of a pickling jar. Background Art

[0002] During the fermentation process of pickled vegetables or salted vegetables, strict oxygen avoidance is required, because the entry of oxygen will cause the growth of aerobic bacteria and deteriorate the flavor of pickled vegetables. When pickled vegetables ferment, gas is generated. The design of the pickling jar needs to meet the requirement of oxygen avoidance, but usually it cannot be designed to be strictly airtight to facilitate the discharge of the gas generated during fermentation. Usually, the pickling jar is designed to have a V-shaped rim at the mouth of the jar. Water is placed in the V-shaped rim groove, and the lower edge of the lid of the pickling jar is immersed in the water to achieve the purpose of oxygen avoidance and exhaust through water sealing. Part of the water in this V-shaped rim groove is exposed to the air, and the water is easy to volatilize. If not well managed, when the water volatilizes completely, oxygen enters the jar, and it is also easy to breed mosquitoes and mildew due to the water, which is not conducive to food hygiene and not convenient for daily management.

[0003] Therefore, the existing pickling jars have the following deficiencies due to the use of water sealing along the rim: 1. It is inconvenient to clean the water along the rim, and the water along the rim that is not cleaned for a long time is prone to breeding maggots; 2. After the water along the rim dries up, air enters the jar, causing the food in the jar to rot and deteriorate, and generating harmful substances such as nitrite. The commonly used local method at present is to clean the rim thoroughly and replace it with clean water every time after taking out the vegetables, and then cover the upper part of the whole pickling jar with a plastic bag. The advantages are as follows: 1. Dust from the outside cannot fall into the inside, which is beneficial to the cleanliness of the water along the rim; 2. The volatilization of the water along the rim is reduced, thus prolonging the time for the water to dry up. Although this local method prolongs the replacement and drying time of the water along the rim and effectively protects the cleanliness and hygiene of the water along the rim, since the plastic bag covered cannot achieve strict sealing, there are still the following problems: 1. Bacteria, microorganisms, etc. are still easy to enter the water along the rim through the gap between the plastic bag and the jar and breed and grow; 2. The time for the water along the rim to prolong drying is limited; 3. Dust and sundries from the outside are still easy to enter the water along the rim and pollute the water along the rim; 4. If an opaque bag is used, it is necessary to uncover the bag every time to observe the drying situation of the water along the rim; 5. Since the bag is separately covered on the pickling jar, when opening the lid to take out the vegetables, it is necessary to first remove the plastic bag, and then uncover the lid of the jar to take out the vegetables. After taking out the vegetables, it is also necessary to first cover the lid of the jar separately, and then put on the plastic bag. The whole process is rather cumbersome. Moreover, since the lid of the jar is airtight in the plastic bag for a long time, the entire surface of the lid is covered with water vapor or water mist and is particularly slippery, and the lid is prone to slipping and being damaged during the process of opening and closing the lid, especially for the lids of some larger sizes.

[0004] In view of this, there is a need in the market for a water-retaining sealing cover for the rim of a pickling jar with better sealing effect, easy exhaust, easy observation of the water level of the water along the rim, more effective prolongation of the drying time of the water along the rim, and more simple, convenient, reliable lid-opening operation of the pickling jar. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to achieve the sealing of the water in the rim of the pickle jar.

[0006] The technical solution of the present invention to solve the above technical problem is as follows: A water-retaining sealing cover for a pickle jar with adaptive flexible sealing protection, the sealing cover includes an upper sealing body of the sealing cover, a main body of the sealing cover, a lower sealing body of the sealing cover and an air overflow observation component. The annular upper sealing body of the sealing cover, the annular main body of the sealing cover and the annular lower sealing body of the sealing cover are fixedly connected in sequence from top to bottom. Both the upper sealing body of the sealing cover and the lower sealing body of the sealing cover are made of elastic materials. The lower end of the lower sealing body of the sealing cover extends obliquely upward towards the inside thereof and forms a lower sealing part. The air overflow observation component is fixed on the main body of the sealing cover.

[0007] The beneficial effects of the present invention are: The sealing cover is installed outside the jar lid. The main body of the sealing cover provides a supporting effect for the whole sealing cover by its own stiffness and strength to maintain the overall shape of the sealing cover and provide a space between the sealing cover and the jar lid. The upper sealing body of the sealing cover is used for sealing with the jar lid, and the lower sealing body of the sealing cover abuts against the rim of the jar for sealing. When the jar lid is covered, the upper sealing body of the sealing cover and the lower sealing body of the sealing cover are elastically deformed under the action of the gravity of the jar lid and their own elastic forces to achieve adaptive flexible sealing. The gas generated by fermentation can overflow through the air overflow observation component, and at the same time, the air overflow observation component can also be used to observe the water volume in the rim of the jar. For the sealing cover of the present invention, the sealing effect of the water in the rim of the jar is better, the exhaust is easy to carry out, it is easy to observe the water level in the rim of the jar, it can more effectively extend the drying time of the water in the rim of the jar, and the operation of opening the jar lid is more simple, convenient and reliable.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Further, the sealing cover further includes a handle, and the handle is fixedly connected to the upper side wall of the upper sealing body of the sealing cover.

[0010] The beneficial effect of adopting the above further solution is: Through the handle, it is convenient to lift or pick up the sealing cover.

[0011] Further, the number of the handles is at least two and is an even number, and at least two handles are evenly distributed along the circumferential direction on the side wall of the upper sealing body of the sealing cover.

[0012] The beneficial effect of adopting the above further solution is: The upper end of the upper sealing body of the sealing cover can be symmetrically stretched open through the handles, so as to facilitate the disassembly and assembly of the upper sealing body of the sealing cover and the jar lid.

[0013] Furthermore, the gas overflow observation assembly includes a gas overflow observation cover and a gas overflow observation hole opened on the side wall of the sealing cover body, the gas overflow observation cover is made of elastic material, one end of the gas overflow observation cover is fixedly connected to the side wall of the sealing cover body, and the other end covers the gas overflow observation hole under the action of elastic force; the gas overflow observation assembly is a group, or the gas overflow observation assembly is at least two groups, and at least two groups of gas overflow observation assemblies are evenly distributed along the circumferential direction of the side wall of the sealing cover body.

[0014] The beneficial effect of adopting the above further scheme is that the other end of the gas overflow observation cover can be manually lifted up to observe the amount of water in the jar edge through the gas overflow observation hole. When the gas generated by fermentation is large in the natural state, the elastic force of the gas overflow observation cover can be overcome, the gas overflow observation cover can be lifted up, and the gas overflows from the gas overflow observation hole.

[0015] Furthermore, the other end of the gas overflow observation cover has a gas overflow sealing protrusion, and the gas overflow sealing protrusion abuts against the gas overflow observation hole and seals the gas overflow observation hole.

[0016] The beneficial effect of adopting the above further solution is that the sealing effect of the overflow observation hole is better.

[0017] Furthermore, the rigidity of the upper sealing body of the sealing cover is greater than the rigidity of the lower sealing body of the sealing cover.

[0018] The beneficial effect of adopting the above further scheme is: when the altar cover is covered, as the altar cover falls to the edge of the altar due to its own weight, the sealing cover will be pressed downward due to the fixed relative position of the upper sealing body of the sealing cover and the altar cover, so that the lower sealing body of the sealing cover tightly fits around the periphery of the entire altar edge to achieve the overall sealing of the altar edge. Since the upper sealing body of the sealing cover and the lower sealing body of the sealing cover are both elastic and flexible bodies, and the rigidity of the upper sealing body of the sealing cover is greater than the rigidity of the lower sealing body of the sealing cover in the selection of materials, that is, when subjected to the same force, the deformation of the upper sealing body of the sealing cover is less than the deformation of the lower sealing body of the sealing cover. Therefore, in the process of sealing with the altar cover descending, the lower sealing body of the sealing cover first deforms and opens to give way and hugs the altar edge. When the deformation of the lower sealing body of the sealing cover is so large that the force required for its further deformation is greater than the force required for the deformation of the upper sealing body of the sealing cover, the upper sealing body of the sealing cover begins to deform and give way until the altar cover completely sinks and falls to the bottom of the altar edge, thereby achieving the complete sealing of the entire altar cover and the sealing protection of the water on the altar edge. The seal protection of the present invention is adaptive and truly flexible.

[0019] The present invention also provides a pickle jar, which comprises the water-retaining and sealing cover for the pickle jar with self-adaptive flexible sealing protection, a jar body and a jar lid. The jar body has a jar mouth and a jar rim located outside the jar mouth. The jar lid is buckled inside the jar rim. The sealing cover is sleeved outside the jar lid in a sealed manner, and the lower sealing part of the lower sealing body of the sealing cover abuts against and seals the top surface of the jar rim. The jar lid has a jar lid positioning part, and the upper end of the upper sealing body of the sealing cover is detachably connected to the jar lid positioning part. The height difference between the jar lid positioning part and the top surface of the jar rim is less than the height of the sealing cover.

[0020] For the pickle jar of the present invention, by adopting the sealing cover, the sealing effect of the water in the jar rim is better, exhausting air is easier, it is easy to observe the water level of the water in the jar rim, the drying time of the water in the jar rim can be effectively prolonged, and the operation of opening the jar lid is more simple, convenient and reliable.

[0021] Further, the upper end of the jar lid extends radially outward to form the jar lid positioning part, and the upper end of the upper sealing body of the sealing cover abuts against the bottom surface of the jar lid positioning part.

[0022] Alternatively, the upper side wall of the jar lid has an annular groove, the annular groove forms the jar lid positioning part, the inner side of the upper end of the upper sealing body of the sealing cover has an annular protrusion, and the annular protrusion is clamped with the annular groove.

[0023] The present invention also provides a method for sealing a pickle jar, which is realized by adopting the pickle jar and comprises the following steps:

[0024] Step 1: Covering. Sleeving the sealing cover outside the jar lid, stretching the upper end of the upper sealing body of the sealing cover until its diameter is larger than the upper end of the jar lid, and moving the sealing cover downward so that the upper end of the upper sealing body of the sealing cover is hermetically connected to the jar lid positioning part;

[0025] Step 2: Installing the cover. Covering the jar lid inside the jar rim, the lower sealing part of the lower sealing body of the sealing cover abuts against the top surface of the jar rim. Under the action of the elastic force and the gravity of the jar lid, the lower sealing part moves downward, and the lower sealing part is flexibly deformed and closely fits the jar rim.

[0026] For the method for sealing the pickle jar of the present invention, under the action of the gravity of the jar lid and the elastic force of the sealing cover, self-adaptive flexible sealing is realized, the sealing performance is good, and the jar lid is convenient to take and place.

[0033] The principles and features of the present invention will be described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0034] As Figures 1-3 shown, this embodiment provides a water-retaining sealing cover for a pickled vegetable jar with adaptive flexible sealing protection. The sealing cover includes an upper sealing body 1 of the sealing cover, a main body 2 of the sealing cover, a lower sealing body 3 of the sealing cover, and an air overflow observation assembly. The annular upper sealing body 1 of the sealing cover, the annular main body 2 of the sealing cover, and the annular lower sealing body 3 of the sealing cover are fixedly connected in sequence from top to bottom. Both the upper sealing body 1 of the sealing cover and the lower sealing body 3 of the sealing cover are made of elastic materials. The lower end of the lower sealing body 3 of the sealing cover extends obliquely upward towards the inside thereof and forms a lower sealing portion. The air overflow observation assembly is fixed on the main body 2 of the sealing cover.

[0035] The sealing cover is installed outside the jar cover 8. The main body 2 of the sealing cover provides a supporting effect for the whole sealing cover by its own stiffness and strength to maintain the overall shape of the sealing cover and provide a space between the sealing cover and the jar cover 8. The upper sealing body 1 of the sealing cover is used to seal with the jar cover 8, and the lower sealing body 3 of the sealing cover abuts against the jar rim 9 for sealing. When the jar cover 8 is covered, the upper sealing body 1 of the sealing cover and the lower sealing body 3 of the sealing cover are elastically deformed under the action of the gravity of the jar cover 8 and their own elastic forces to achieve adaptive flexible sealing. The gas generated by fermentation can overflow through the air overflow observation assembly. At the same time, the air overflow observation assembly can also be used to observe the water level in the jar rim. For the sealing cover of the present invention, the sealing effect of the water in the jar rim is better, the exhaust is easier, it is easy to observe the water level in the jar rim, the drying time of the water in the jar rim can be effectively extended, and the operation of opening the jar cover is more simple, convenient and reliable.

[0036] Specifically, the material of the sealing body 1 on the sealing cover is a composite of one or more materials among rubber or plastic elastomers. After it is manufactured by methods such as separate injection molding, compression molding, machining, or other methods, it can be installed and fixed to the upper end of the sealing cover main body 2 by means of welding or screw fastening, etc., so as to be tightly connected with the sealing cover main body 2 to form a whole; it can also be integrally and tightly connected with the sealing cover main body 2 by means of one-shot insert injection molding, multi-component injection molding, or secondary (multiple) injection molding.

[0037] Specifically, the material of the sealing cover main body 2 has the stiffness and strength that meet the use requirements. Its material can be a composite of one or more materials among plastics, metals, or ceramics. The sealing cover main body 2 has good stiffness and strength during the installation and use process and will not undergo excessive deformation, especially bending. After the sealing cover main body 2 is manufactured by methods such as separate injection molding, compression molding, machining, or other methods, it can be tightly connected with the sealing body 1 on the sealing cover, the lower sealing body 3 on the sealing cover, and the air overflow observation component to form a whole by means of welding or screw fastening, etc.; it can also be integrally and tightly connected with the sealing body 1 on the sealing cover, the lower sealing body 3 on the sealing cover, and the air overflow observation component by means of multi-component injection molding or insert injection molding.

[0038] Specifically, the material of the lower sealing body 3 on the sealing cover is a composite of one or more materials among rubber or plastic elastomers. After it is manufactured by methods such as separate injection molding, compression molding, machining, or other methods, it can be installed and fixed to the lower end of the sealing cover main body 2 by means of welding or screw fastening, etc., and be tightly connected with the sealing cover main body 2 to form a whole; it can also be integrally and tightly connected with the sealing cover main body 2 by means of multi-component injection molding, secondary (multiple) injection molding, or insert injection molding.

[0039] On the basis of the above scheme, the sealing cover further includes a handle 4, and the handle 4 is fixedly connected to the upper side wall of the sealing body 1 on the sealing cover.

[0040] Through the handle 4, it is convenient to lift or pick up and place the sealing cover.

[0041] On the basis of the above scheme, there are at least two handles 4, and the number is even. At least two handles 4 are evenly distributed along the circumferential direction on the side wall of the sealing body 1 on the sealing cover.

[0042] The upper end of the sealing body 1 on the sealing cover can be symmetrically stretched open by the handle 4, facilitating the disassembly and assembly of the sealing body 1 on the sealing cover and the jar lid 8. Specifically, during installation, the symmetrically arranged handles 4 on both sides are stretched forcefully to expand the upper end of the sealing body 1 on the sealing cover outward until it is larger than the top end of the jar lid 8, and then it is moved downward to hoop the sealing body 1 on the sealing cover onto the positioning part of the jar lid. When opening the jar lid 8, just lift the symmetrically arranged handles 4 on both sides to lift the entire jar lid 8, realizing the operations of opening and closing the lid.

[0043] Specifically, preferably two or four handles 4 are symmetrically and evenly distributed around the upper end of the sealing body 1 on the sealing cover. Their manufacturing method can be that after being separately injection-molded, compression-molded, machined by mechanical processing or other methods, they are installed and fixed around the upper end of the sealing body 1 on the sealing cover by means of welding, screw fastening, etc. When using this method, the material of the handle 4 can be various materials such as plastic, rubber, metal or ceramic that meet the usage requirements in terms of strength; it can also be that the handle 4 and the sealing body 1 on the sealing cover are injection-molded into an integral body using one-component or multi-component injection molding. When using this method, the material of the handle 4 can be polymer materials such as plastic and rubber. If the material of the handle 4 is the same as that of the sealing body on the sealing cover, one-component one-time injection molding can be used, or two-component injection molding or secondary injection molding can also be used. If the material of the handle 4 is different from that of the sealing body 1 on the sealing cover, two-component injection molding or secondary injection molding is used.

[0044] Based on the above solution, the air overflow observation component includes an air overflow observation cover 5 and an air overflow observation hole 6 opened on the side wall of the sealing cover main body 2. The air overflow observation cover 5 is made of elastic material. One end of the air overflow observation cover 5 is fixedly connected to the side wall of the sealing cover main body 2, and the other end covers the air overflow observation hole 6 under the action of elastic force; the air overflow observation component is a group; or the air overflow observation component is at least two groups, and at least two groups of the air overflow observation components are evenly distributed along the circumferential direction on the side wall of the sealing cover main body 2.

[0045] Manually lift the other end of the air overflow observation cover 5, and the water volume in the jar rim 9 can be observed through the air overflow observation hole 6; after observation, release the hand, and the air overflow observation cover 5 automatically resets under its own elastic force and covers and seals the air overflow observation hole 6. In the natural placement state, when there is more gas generated by fermentation, it can overcome the elastic force of the air overflow observation cover 5 and push up the air overflow observation cover 5, and the gas overflows from the air overflow observation hole 6.

[0046] Specifically, the material of the air overflow observation cover 5 is a composite of one or more materials of rubber or plastic elastomer. After it is manufactured by methods such as single injection molding, compression molding, machining, or other methods, it can be installed and fixed on the sealing cover main body 2 by means of welding or screw fastening; it can also be formed into an integral part with the sealing cover main body 2 by methods such as multi-component injection molding, secondary (multiple) injection molding, insert injection molding, or pressing.

[0047] Specifically, gases are generated during the fermentation of pickles in the altar, and these gases overflow into the sealing cover through the water in the altar edge. When the pressure of the gases generated during the fermentation of pickles in the altar makes the air pressure inside the sealing cover greater than the air pressure outside the sealing cover, and the pressure exerted on the air overflow observation cover 5 is greater than its elastic force, the gases inside the sealing cover can push open the air overflow observation cover 5 and overflow from the air overflow hole 6; when the gases inside the sealing cover overflow, and the air pressure inside the sealing cover drops to be equal to or lower than the air pressure outside the sealing cover, the air overflow observation cover 5 uses its elastic force to press on the air overflow hole 6 to achieve sealing, so that the inside of the sealing cover is always in a sealed state (no external gases or sundries enter), which well prevents microorganisms, bacteria, dust, etc. outside the cover from entering the water in the altar edge inside the sealing cover, thus preventing the growth or pollution of the water in the altar edge and keeping the water in the altar edge clean. At the same time, it also well prevents the volatilization and loss of the water in the altar edge inside the sealing cover, greatly extending the time when the water in the altar edge dries up. The above process does not require manual intervention, reducing the workload.

[0048] On the basis of the above solution, the other end of the air overflow observation cover 5 has an air overflow sealing convex part, and the air overflow sealing convex part abuts against the air overflow hole 6 and seals the air overflow hole 6.

[0049] By setting the air overflow sealing convex part, the sealing effect of the air overflow hole 6 is better.

[0050] Preferably, the air overflow hole 6 is a circular hole, and the air overflow sealing convex part is a hemispherical convex, which has good adaptability and sealing performance with the circular hole. The hemispherical convex of the air overflow sealing convex part is correspondingly located at the air overflow hole 6. During use, the hemispherical convex uses the elasticity of the air overflow observation cover 5 to just seal the air overflow hole 6 on the air overflow observation cover 5, thus realizing real-time air overflow and flexible sealing during use.

[0051] On the basis of the above solution, the stiffness of the sealing body 1 on the sealing cover is greater than the stiffness of the lower sealing body 3 of the sealing cover.

[0052] When the altar cover 8 is covered, as the altar cover 8 descends due to its own weight onto the altar edge 9, since the relative positions of the sealing body 1 on the sealing cover and the altar cover 8 are fixed, the sealing cover will be pressed downward, so that the lower sealing body 3 of the sealing cover tightly fits around and clamps the entire periphery of the altar edge 9 to achieve the overall sealing of the altar edge 9. Since both the upper sealing body 1 on the sealing cover and the lower sealing body 3 of the sealing cover are elastic and flexible bodies, and the stiffness of the upper sealing body 1 on the sealing cover is greater than that of the lower sealing body 3 of the sealing cover in terms of material selection, that is to say, when subjected to the same acting force, the deformation amount of the upper sealing body 1 on the sealing cover is smaller than that of the lower sealing body 3 of the sealing cover. Therefore, during the process of the altar cover 8 descending and being sealed, first, the lower sealing body 3 of the sealing cover deforms and opens to make way and then clamps and fits the altar edge 9. When the deformation amount of the lower sealing body 3 of the sealing cover is so large that the acting force required for its further deformation is greater than the acting force required for the deformation of the upper sealing body 1 on the sealing cover, the upper sealing body 1 on the sealing cover begins to deform and make way until the altar cover 8 completely sinks to the bottom of the altar edge 9, thus achieving the complete sealing of the entire altar cover 8 and the sealing protection of the altar edge water. The sealing protection of the present invention is self-adaptive and truly flexible.

[0053] As Figure 4 shown, this embodiment also provides a pickled vegetable altar, including the pickled vegetable altar water-retaining sealing cover with the above-mentioned self-adaptive flexible sealing protection, and further including an altar body 7 and an altar cover 8. The altar body 7 has an altar mouth and an altar edge 9 located outside the altar mouth. The altar cover 8 is buckled inside the altar edge 9. The sealing cover is hermetically sleeved outside the altar cover 8, and the lower sealing part of the lower sealing body 3 of the sealing cover abuts and seals against the top surface of the altar edge 9. The altar cover 8 has an altar cover positioning part, and the upper end of the upper sealing body 1 of the sealing cover is detachably connected to the altar cover positioning part. The height difference between the altar cover positioning part and the top surface of the altar edge 9 is less than the height of the sealing cover.

[0054] The pickled vegetable altar of the present invention adopts the above-mentioned sealing cover, with better sealing effect of the altar edge water, easier exhaust, easier observation of the water level of the altar edge water, more effective extension of the dry time of the altar edge water, and more simple, convenient and reliable opening operation of the altar cover.

[0055] The sealing cover is merely an additional accessory and can be applied to any existing pickled vegetable altar without the need to improve the structure of the pickled vegetable altar itself or purchase a new pickled vegetable altar.

[0056] Compared with the solution where the sealing cover is threadedly connected to the rim of the altar and a sealing ring is provided at the position where the two are in contact, simply setting the sealing ring, the sealing effect entirely depends on the pressing force generated by the depth of the thread fit. In the process of removing or placing the altar cover 8 in this solution, one only needs to directly lift the sealing cover to remove the altar cover 8 or place the altar cover 8 into the rim 9 of the altar. The altar cover 8 can be well sealed by its own weight sinking. This process can be completed without much human participation and has good self - adaptability and flexibility. However, for the threaded connection solution, the altar cover needs to be tightened on the rim through threaded connection to achieve the sealing of the altar cover and the sealing of the water on the rim. When removing the altar cover, the threaded fit between them also needs to be loosened before the altar cover can be removed. The operations of these processes are more complex and do not have the self - adaptability, flexibility, and convenience of this solution.

[0057] For the altar cover positioning part, in one implementation, the upper end of the altar cover 8 extends radially outward to form the altar cover positioning part, and the upper end of the sealing body 1 on the sealing cover abuts against the bottom surface of the altar cover positioning part.

[0058] For the altar cover positioning part, in another implementation, the upper side wall of the altar cover 8 has an annular groove, and the annular groove forms the altar cover positioning part. The inner side of the upper end of the sealing body 1 on the sealing cover has an annular protrusion, and the annular protrusion is engaged with the annular groove.

[0059] This embodiment also provides a method for sealing a pickled vegetable altar, which is implemented by using the pickled vegetable altar and includes the following steps:

[0060] Step 1: Covering. The sealing cover is sleeved outside the altar cover 8, and the upper end of the sealing body 1 on the sealing cover is stretched until its diameter is greater than the upper end of the altar cover 8, and then the sealing cover is moved downward so that the upper end of the sealing body 1 on the sealing cover is hermetically connected to the altar cover positioning part.

[0061] Step 2: Installing the cover. The altar cover 8 is placed inside the rim 9 of the altar. The lower sealing part of the lower sealing body 3 of the sealing cover abuts against the top surface of the rim 9. Under the action of the elastic force and the gravity of the altar cover 8, the lower sealing part moves downward, and the lower sealing part deforms flexibly and closely fits the rim 9.

[0062] The method for sealing the pickled vegetable altar of the present invention realizes self - adaptive flexible sealing under the action of the gravity of the altar cover 8 and the elastic force of the sealing cover, has good sealing performance, and is convenient for removing and placing the altar cover 8.

[0063] On the basis of the above solution, the stiffness of the upper seal body 1 of the sealing cover is greater than that of the lower seal body 3 of the sealing cover. The specific content of the second step is as follows: Cover the jar lid 8 in the jar rim 9. The lower sealing part first abuts against the top surface of the jar rim 9. Under the action of the elastic force and the gravity of the jar lid 8, the lower sealing part moves downward. The lower sealing part deforms flexibly and closely fits the jar rim 9. The upper seal body 1 of the sealing cover deforms flexibly until the jar lid 8 completely sinks and is located at the bottom of the jar rim 9.

[0064] The pickling jar sealing method of the present invention has self - adaptability and true flexibility, and is easy to operate.

[0065] Specifically, when using the pickling jar, before step one, it also includes: putting pickles into the jar body 7, adding water to the jar rim 9, and covering the jar lid 8.

[0066] When using the pickling jar, when it is necessary to open the jar lid 8 to take vegetables, just lift the symmetric handles 4 by hand to lift the sealing cover. The jar lid is lifted together with the sealing cover under the hoop - holding action of the upper end of the upper seal body 1 of the sealing cover, and then the jar lid 8 can be opened. Due to the rigid supporting action of the sealing cover main body 2, after the jar lid 8 is opened, it can be directly placed on the ground, and the lower end of the sealing cover main body 2 contacts the ground, avoiding the jar lid 8 directly contacting the ground and bringing in dust, bacteria, etc. into the water in the jar rim. After taking the vegetables, just lift the symmetric handles 4 by hand to lift the sealing cover. The jar lid 8 is lifted together with the sealing cover under the hoop - holding action of the upper end of the upper seal body 1 of the sealing cover, and then it is put into the jar rim 9, that is, the covering and sealing of the jar lid are completed.
