In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise stated.

[0036] Embodiment 1

[0037] Referring to Figure 1 , Figure 7 , Figure 8 , the present application provides a sealing ring for sealing between a cover and a containing body; the sealing ring 1 is arranged on a fixed part in the cover 2, and the fixed part is used to fix the sealing ring 1 in the cover to cooperate with the containing body for sealing, wherein the fixed part can be an inner ring rib 21 arranged in the middle of the cover 2, and the sealing ring 1 is sleeved on the periphery of the inner ring rib 21 and tightly cooperates with the inner ring rib 21.

[0038] The sealing ring 1 includes a cladding part 11 and a sealing part connected thereto, wherein:

[0039] As shown in Figure 7 and Figure 8 , the cladding part 11 abuts against the bottom end of the fixed part and cooperates with the fixed part to form a horizontal sealing structure; the sealing part is used to form a vertical sealing structure with the inner wall of the containing body 3 when the cover 2 is fixed on the containing body 3.

[0040] After the sealing ring 1 is fixed on the fixed part in the cover 2, as shown in Figure 8 , the cladding part 11 abuts against the horizontal sealing structure formed by the fixed part, which can prevent the contents of the containing body 3 from entering the gap between the inner wall of the fixed part and the sealing ring 1 and the gap between the inner wall of the fixed part and the cover 2, thereby preventing leakage, especially when the containing body with the fixed cover is inverted, due to the sealing effect of the cladding part 11, the contents are difficult to enter the gap between the sealing ring 1 and the fixed part, thereby preventing leakage; at the same time, the sealing part is in interference fit with the inner wall of the containing body, which prevents the contents from leaking along the inner wall of the containing body 3 and prevents external gas and liquid from entering; the cladding part 11 and the sealing part of the sealing ring 1 can form a double-sealing structure from the horizontal direction and the vertical direction, respectively, which can provide multiple protection for the objects in the containing body and has good sealing effect.

[0041] As a more preferred embodiment of the present embodiment, the end of the sealing ring 1 close to the accommodating body 3 extends to the radial inner side of the sealing ring 1 to form a covering part 11, and the end of the sealing ring 1 cooperating with the inner wall of the accommodating body 3 extends to the radial outer side of the sealing ring 1 to form a sealing part.

[0042] In addition to cooperating with the fixed part in the cover 2 to form a horizontal sealing structure, the covering part 11 can prevent the sealing ring 1 from being displaced when abutting the bottom end of the fixed part when the accommodating body 3 is buckled or covered on the cover 2, thereby playing a better positioning role.

[0043] As a more preferred embodiment of the present embodiment, as shown in Figure 1 , Figure 2 , the sealing part is an annular sealing strip 12 arranged on the outer periphery of the ring body of the sealing ring 1.

[0044] The sealing ring 1 is tightly fitted in the cover 2, and by utilizing the characteristics that the elastic material can be elastically deformed under stress, the annular sealing strip 12 is arranged on the ring of the sealing ring 1 and is in interference fit with the inner wall of the accommodating body 3, and the annular sealing strip 12 is elastically deformed when being pressed against the inner wall to play a role of rapid sealing.

[0045] Among them, the contact part of the annular sealing strip 12 with the inner wall of the accommodating body 3 is relatively thin, and is more prone to elastic deformation during interference fit with the inner wall to enhance the sealing effect.

[0046] The sealing ring 1 is designed according to the shape of the tank body, and in order to ensure the strength of the annular sealing strip, the inner side of the sealing ring 1 is not deformed when the accommodating body 3 is loaded, and preferably, the thickness of the inner side rubber position connected with the annular sealing strip 12 is 3-3.5mm, as shown in Figure 4 , the covering part 11 and the annular sealing strip 12 can be arranged on the same end of the sealing ring 1, at this time the thickness of the covering part 11 can be used to enhance the strength of the annular sealing strip 12. It should be understood that the above-mentioned sealing part can also not be arranged at the end of the sealing ring 1, but when the cover 2 is buckled, the horizontal height of the lowest part of the annular sealing strip 12 should not be higher than the height of the upper edge of the accommodating body 3.

[0047] In order to further enhance the strength of the annular sealing strip 12, as shown in Figure 1 and Figure 4 , the thickness of the annular sealing strip 12 gradually decreases from the inside to the outside along the radial direction of the sealing ring 1.

[0048] The side of the annular sealing strip 12 away from the ring body of the sealing ring 1 is relatively thin and is prone to elastic deformation when cooperating with the inner wall of the accommodating body 3 to play a better sealing effect, and the side of the annular sealing strip 12 close to the ring body of the sealing ring 1 is relatively thick to enhance the strength of the annular sealing strip 12 and prevent the inner side of the annular sealing strip 12 from being deformed when cooperating with the accommodating body 3 for sealing.

[0049] As a more preferred embodiment of the present application, referring to Figure 1 , Figure 2 and Figure 3 , Figure 4 , the annular sealing strip 12 is arranged in multiple rows along the axial direction of the sealing ring 1. Multiple rows refer to two or more rows, and the multiple rows of annular sealing strips 12 can further ensure the sealing effect by interference fit with the inner wall of the accommodating body 3.

[0050] As a more preferred embodiment of the present application, referring to Figure 1 , Figure 3 , Figure 4 , the covering portion 11 is an annular abutting table extending to the radially inner side of the sealing ring 1, and the upper surface of the annular abutting table abuts against the fixing portion.

[0051] During assembly, the end of the sealing ring 1 away from the covering portion 11 is first fitted into the inner ring rib 21 in the cover body 2, and after the upper surface of the annular abutting table abuts against the bottom end of the inner ring rib 21, the sealing ring 1 is fixed; the abutting table and the annular sealing strip 12 are integrally formed with the ring body of the sealing ring 1.

[0052] Preferably, in order to ensure that the sealing ring 1 has good elasticity, the sealing ring 1 is made of rubber or silicone. For example, the sealing ring 1 is made of food-grade TPE soft rubber material.

[0053] As a more preferred embodiment of the present application, referring to Figure 1 , Figure 3 and Figure 4 , the inner ring side of the sealing ring 1 is provided with a protruding portion that interferes with the fixing portion in the cover body 2.

[0054] The function of the protruding portion is to interfere with the inner ring rib 21 in the cover body 2 while facilitating the assembly of the sealing ring 1. The protruding portion and the sealing ring 1 can be integrally formed by a mold during manufacturing.

[0055] As an optional embodiment, referring to Figure 1 and Figure 4 , the protruding portion is a ring-shaped boss 13 arranged in multiple rows along the axial direction of the sealing ring 1, and each ring-shaped boss 13 is composed of segments arranged in multiple rows along the circumferential direction.

[0056] In the present embodiment, four circular bosses 13 are designed on the inner side of the sealing ring 1, each segment is spaced apart, the height is about 0.3mm-0.5mm, the width is about 3.5mm, and there are three rings. The segmented boss 13 structure is easier to assemble into the periphery of the inner ring rib 21. The bosses 13 are uniformly distributed on the inner side of the sealing ring 1 and tightly interfere with the cover body 2, so that the sealing ring 1 is not easy to fall off during the opening or buckling process of the cover body 2.

[0057] In order to enhance the strength of the entire sealing ring 1 and prevent the sealing ring 1 from deforming and affecting the sealing effect when it is sleeved on the inner ring rib 21, as a better implementation of this embodiment, refer to Figure 1 、 Figure 2 and Figure 4 As shown, the end of the sealing ring 1 is provided with a ring-shaped reinforcing eave 14 that matches the inner wall of the cover body 2.

[0058] Reference Figure 7 and Figure 8 As shown, the extension length of the reinforcing eaves 14 can be equal to or slightly less than the distance from the sealing ring 1 to the inner ring rib 21 of the cover body 2. The provision of the reinforcing eaves 14 can further prevent the sealing ring 1 from being deformed during assembly.

[0059] In this embodiment, two reinforcing eaves 14 are provided on the upper and lower parts of the sealing ring 1 to enhance the strength of the sealing ring 1 .

[0060] In order to prevent the sealing ring 1 from being unable to be installed due to the negative pressure formed by the reinforcement eaves 14 and the inner wall of the cover body 2 when the sealing ring 1 is sleeved on the outer periphery of the inner ring rib 21, Figure 1 As shown, a glue reducing groove 16 is provided on the outer peripheral edge of the reinforcing eave 14 .

[0061] In order to facilitate the installation of the sealing ring 1, a trapezoidal rubber reduction groove 16 is opened on the outer side of the sealing ring 1 and the matching part of the cover 2, which is about 5mm long and about 0.6mm-0.8mm wide, with an interval of 14mm and a surrounding design (such as Figure 1 and Figure 5 As shown), it is possible to prevent vacuum from being installed. Those skilled in the art can adjust the size and shape of the above-mentioned glue reduction groove 16 according to actual conditions, and are not limited thereto.

[0062] As a more preferred implementation of this embodiment, in order to further enhance the strength of the sealing ring 1 , reinforcing ribs 15 are provided on the outer periphery of the ring body of the sealing ring 1 at intervals, and the reinforcing ribs 15 are connected between the upper and lower reinforcing ridges 14 .

[0063] The thickness of the reinforcing ribs 15 is about 0.7 mm, and they can be evenly distributed on the outer periphery of the sealing ring 1 at intervals of 14 mm. Figure 1 and Figure 5 As shown, it is convenient for the mold slider to be formed, but it is not limited to the above dimensions.

[0064] The vertically arranged reinforcing eaves 14 and the laterally extending reinforcing ribs 15 can enhance the strength of the sealing ring 1 in different directions, so that the annular sealing strip 12 can be easily elastically deformed while ensuring the structural strength of the entire sealing ring 1.

[0065] The shape of the sealing ring 1 is determined according to the shape of the cover 2 and the container 3. Figures 1-8The sealing ring 1 in the figure is oval, and in addition, the sealing ring 1 can also be circular, triangular, rectangular, square, or prismatic.

[0066] Embodiment 2

[0067] The embodiment provides a storage device, which comprises a cover 2, a containing body 3, and the sealing ring 1.

[0068] The storage device can be a storage tank, a storage bottle, or a storage cylinder, and the containing body 3 can be a tank body, a bottle body, or a cylinder body.

[0069] Referring to Figures 5-8 The storage device provided in the embodiment is a storage tank, and the containing body 3 is a tank body in the embodiment. The tank body is oval, and the sealing ring 1 is also oval. According to different shapes of the storage tank, the sealing ring 1 can be designed to be circular, triangular, rectangular, square, or prismatic, and has the same use function and effect. Different shapes can present different visual effects. Customers can choose different styles according to preferences, so that the multiple selection requirements of customers are met.

[0070] The storage tank comprises the cover 2, the sealing ring 1, a spoon 4, and a tank body, wherein the spoon 4 can be fixed between the inner ring ribs 21; and the function requirement of the product is met by using the least number of products.

[0071] The product is simple to assemble. The annular sealing strip 12 of the sealing ring 1 can be designed to be two or more according to the actual assembly condition of the product, and is in interference fit with the inner wall of the tank body. The tank body extrudes the annular sealing strip 12, so that the annular sealing strip 12 is elastically deformed to a certain degree, and the rapid sealing effect is achieved. The content in the tank body is prevented from leaking from the inner wall of the tank body. On the other hand, the annular abutting table on the sealing ring 1 is used as the covering part 11 to be attached to the end surface of the cover 2, so that the sealing structure in the horizontal direction is formed.

[0072] The annular sealing strip 12 and the covering part 11 can play a double sealing role, and solve the problem that the cover and the tank body cannot be sealed or the sealing performance is poor. The above-mentioned storage tank is placed upside down for several hours, and no water is overflowed, so that the sealing effect is good. The storage tank is especially suitable for being used on a storage device with high sealing performance requirement, such as food sealing.

[0073] The storage tank provided in the embodiment is widely used in every family life, is convenient to use, has good sealing performance, and has good use value and sales space.

[0074] In the description of the present specification, specific features, structures, or characteristics can be combined in any one or more embodiments or examples in a suitable manner.
