[0002] At present, containers, for example, in a cup, usually use silica gel as a sealing ring, which is single in type and cannot meet the development needs of products.
[0003] The existing thermoplastic elastomer material ring, similar to a rubber ring, although has elasticity and flexibility, but its strength is relatively high, and it is not easy to deform when sealing the container, which is prone to water leakage and cannot be used as a sealing ring for a container. CONTENT OF THE UTILITY MODEL
[0004] Therefore, the purpose of the present application is to provide a sealing ring and a container to solve the problem that the existing elastic material ring cannot be used as a sealing ring for a container.

[0007] In some embodiments, the elastic matrix layer comprises a first matrix layer and a second matrix layer, and a plurality of the inorganic particles are distributed in the first matrix layer.
[0008] In these embodiments, by embedding inorganic particles only in the first matrix layer and not embedding inorganic particles in the second matrix layer, the strength of the sealing ring can be considered on the basis of ensuring the sealing performance.
[0009] In other embodiments, the elastic matrix layer comprises a first matrix layer and a second matrix layer, and the number of the inorganic particles is reduced in the direction from the first matrix layer to the second matrix layer.
[0010] In these embodiments, the inorganic particles dispersed in the elastic matrix layer are gradiently distributed, which can also consider the strength of the sealing ring on the basis of ensuring the sealing performance.

[0013] In some embodiments, the elastic base layer is annular, and the number of inorganic particles in the elastic base layer is 200 million to 2 billion.
[0014] In these embodiments, the distribution of inorganic particles in the elastic base layer can better provide a deformation space when the sealing ring deforms, so as to increase the deformation ability of the sealing ring.
[0015] In some embodiments, the Shore A hardness of the first base layer is 40°-80°, the first base layer has good elasticity and can deform to a certain extent when subjected to pressure, thereby being able to seal the small gap between the cup body and the cup cover, improve the sealing effect, and have good wear resistance, thereby being able to guarantee the service life of the sealing ring.

[0017] In some embodiments, the thickness of the first base layer is 20 microns to 100 microns, and the thickness of the first base layer 11 affects the sealing performance and strength of the sealing ring. If the thickness is too thin, the buffering distance is not enough when sealing, which can easily lead to poor sealing effect. If the thickness is too thick, the buffering distance is too abundant when sealing, which can easily affect the overall strength of the sealing ring.

[0022] In some embodiments, part of the inorganic molecular sieve particles are exposed on the surface of the elastic matrix layer, can adsorb odor, and are beneficial to cleaning, so as to ensure the odor resistance performance of the sealing ring.
[0023] In some embodiments, the inorganic molecular sieve particles include one of sodium-based molecular sieve, potassium-based molecular sieve and calcium-based molecular sieve. These molecular sieve materials have excellent adsorption performance and are easy to clean, which can further improve the odor resistance performance of the sealing ring during use.

[0043] In addition, in the description of the examples, when it is considered that a detailed description of the related components or functions known to be understood will cause ambiguity in the interpretation of the present application, such a detailed description will be omitted.
[0044] The embodiments of the present application will be described below with reference to Figures 1 to 5 to introduce the sealing ring provided by the embodiments of the present application.
[0045] According to the embodiments of the first aspect of the present application, a sealing ring for a container is provided, wherein, as shown in Figures 1 to 4 the sealing ring 10 comprises an elastic matrix layer, and a plurality of inorganic particles 111 are distributed in the elastic matrix layer, and the inorganic particles 111 are used to provide a deformation space of the elastic matrix layer when deformed, so as to increase the deformation ability of the elastic matrix layer.
[0046] According to the sealing ring provided in the embodiment of this utility model, inorganic particles 111 are distributed in the elastic matrix layer. The inorganic particles 111 are used to provide deformation space for the elastic matrix layer during deformation, thereby increasing the deformation capacity of the elastic matrix layer and thus enabling it to function as a sealing ring for a container, thereby improving the sealing performance of the container.
[0047] In existing technologies, silicone is typically used as a sealing ring. Silicone itself is porous and has a strong adsorption capacity, easily adsorbing and retaining odor molecules from beverages. After the beverage is soaked, the odor of the beverage will remain inside the container.
[0048] According to the sealing ring provided in the embodiment of this utility model, the elastic matrix layer is a thermoplastic elastic matrix layer, specifically a thermoplastic polyurethane elastomer matrix or a styrene thermoplastic elastomer matrix. These matrices themselves are not easily chemically bonded or adsorb odor molecules, thereby ensuring that the sealing ring has good odor-proof performance.
[0049] Furthermore, according to this application, a plurality of inorganic particles 111 are distributed in the elastic matrix layer. These inorganic particles 111 provide deformation space for the elastic matrix layer during deformation, thereby increasing its deformation capacity. Here, the deformation space is an aggregate of the deformation gaps provided by each of the inorganic particles 111. This means that there are gaps between the inorganic particles 111 or between the particles and the matrix layer within the elastic matrix layer, allowing the matrix layer to deform under external force. Taking the total volume of the elastic matrix layer as 100%, the total volume of the deformation space is no greater than 15% of the total volume of the elastic matrix layer. As an example, the total volume of the elastic matrix layer is S1, and the total volume of the deformation space is S2, where S2 is no greater than 15% of S1. Specifically, when the elastic matrix layer is compressed, it can deform by means of the gaps between itself and the inorganic particles 111. Here, the inorganic particles form a porous structure within the elastic matrix layer. To ensure that the sealing ring does not bind to odor molecules during deformation, these porous portions are composed of inorganic particles, thus guaranteeing the container's odor-proof performance to a certain extent. This is because inorganic particles themselves do not easily adsorb or bind odor molecules; therefore, even if the sealing ring comes into contact with the container and deforms, these pores will not become channels for odor molecules to penetrate.
[0050] In this application, the shape of the sealing ring is not limited; the shape of the sealing ring itself can be set according to the connection between the cup body and the cup lid. For example, the shape of the sealing ring can be set to a "U"-shaped structure or an "I"-shaped structure, etc. All of these shapes can be set to provide a corresponding sealing structure according to the specific structure between the cup lid and the cup body.
[0051] According to the present application, the inorganic particles affect the strength of the sealing ring. In order to reduce the influence on the strength of the sealing ring, avoid affecting the combination of the sealing ring and the container due to excessive deformation, and avoid the problems of weak combination or easy displacement, etc. The distribution of the inorganic particles can be controlled.
[0052] In some embodiments, the elastic matrix layer includes a first matrix layer 11 and a second matrix layer 12, and a plurality of inorganic particles 111 are distributed in the first matrix layer 11.
[0053] In these embodiments, by embedding inorganic particles only in the first matrix layer, and not embedding inorganic particles in the second matrix layer 12, the strength of the sealing ring can be considered on the basis of ensuring the sealing performance.
[0054] In other embodiments, the elastic matrix layer includes a first matrix layer 11 and a second matrix layer 12, and the number of inorganic particles 111 decreases from the first matrix layer 11 to the second matrix layer 12. That is, the inorganic particles are distributed in a decreasing trend along the thickness direction of the elastic matrix layer. It can be understood that the inorganic particles gradually change from one side to the other side in the elastic matrix layer of the sealing ring.
[0055] In these embodiments, the inorganic particles 111 dispersed in the elastic matrix layer are distributed in a gradient, which can also consider the strength of the sealing ring on the basis of ensuring the sealing performance.
[0056] According to the present application, the elastic matrix layer is annular, the number of inorganic particles 111 in the elastic matrix layer is 200 million to 2 billion, and the number of inorganic particles 111 in the elastic matrix layer per square centimeter on the surface of the elastic matrix layer is 100,000 to 2 million.
[0057] In these embodiments, the distribution of the inorganic particles 111 in the elastic matrix layer can better provide a deformation space when the sealing ring deforms, thereby increasing the deformation ability of the sealing ring.
[0058] Taking the example of a plurality of inorganic particles 111 distributed in the first matrix layer 11, the manufacturing method of the elastic matrix layer according to the present application is specifically described to make the technical solution of the present application more complete.
[0059] In this application, the first matrix layer 11 and the second matrix layer 12 can be obtained independently and then connected using existing connection methods. Specifically, a mixture of elastic material and inorganic particles can be extruded to form the first matrix layer 11 containing inorganic particles 111, and the elastic material can be extruded to form the second matrix layer 12. The two layers are then bonded together to obtain the elastic matrix layer. It should be noted that although this application distinguishes between the first matrix layer 11 and the second matrix layer 12 and describes a separately formed elastic matrix layer, this does not mean that the elastic matrix layer of this application cannot be integrally formed. In some embodiments, the first matrix layer 11 and the second matrix layer 12 can be integrally formed.
[0060] In some embodiments, the first substrate layer and the second substrate layer are connected by mortise and tenon joints, that is, one of the bonding surfaces has multiple protrusions and the other of the bonding surface has multiple grooves, and the protrusions are inserted into the corresponding grooves to enhance the bonding performance.
[0061] like Figure 5 As shown, the first substrate layer 11 has multiple protrusions on its mating surface, and the second substrate layer 12 has multiple grooves on its mating surface. The multiple protrusions are inserted into the corresponding grooves, so that the first substrate layer 11 and the second substrate layer 12 are mortised and tenoned together.
[0062] In these embodiments, the first substrate layer 11 and the second substrate layer 12 are mortised and tenoned together, and the two have good bonding performance, thereby ensuring the overall performance of the elastic substrate layer as a sealing ring.
[0063] According to this application, the thickness of the first substrate layer 11 affects the sealing performance and strength of the sealing ring. If the thickness is too thin, the buffer distance during sealing will be insufficient, which may lead to poor sealing performance; if the thickness is too thick, the buffer distance during sealing will be too ample, which may affect the overall strength of the sealing ring. In an exemplary embodiment, the thickness of the first substrate layer 11 is 20 micrometers to 100 micrometers.
[0064] In some embodiments, the Shore A hardness of the first substrate layer 11 is 40°-80°. The first substrate layer has good elasticity and can deform to a certain extent when subjected to pressure, thereby sealing the tiny gap between the cup body and the cup lid, improving the sealing effect, and has good wear resistance, which can ensure the service life of the sealing ring.
[0065] According to the application, the second base layer 12 mainly plays a supporting and reinforcing role to further guarantee the strength of the overall sealing ring, so as to avoid affecting the combination of the sealing ring and the container due to excessive deformation, and to avoid problems such as weak combination or easy displacement. As an example, the thickness of the second base layer 12 is 100 microns-300 microns, so that the strength can be guaranteed while avoiding material waste and installation difficulties caused by excessive thickness.
[0066] In some embodiments, the Shore A hardness of the second base layer 12 is 10°-100°, which can adapt to different application scenarios and sealing requirements.
[0067] In some embodiments, the inorganic particles 111 are inorganic molecular sieve particles with a porous structure inside.
[0068] In these embodiments, the inorganic particles added to the elastic base layer are inorganic molecular sieve particles with a porous structure inside. On the one hand, these particles can provide more deformation space to guarantee the sealing performance of the sealing ring. On the other hand, the inorganic molecular sieve particles with a porous structure are inorganic and do not contain groups that can combine with odor molecules, so they are not easy to combine with odor molecules by chemical combination. Moreover, even if they have adsorbed odor, they can be quickly and conveniently cleaned and eliminated by sunlight, washing, heating, etc., so as not to affect the odor resistance of the sealing ring.
[0069] In some embodiments, part of the inorganic molecular sieve particles are exposed on the surface of the elastic base layer to inhibit odor. Specifically, the exposed inorganic molecular sieve particles can adsorb odor and facilitate cleaning, so as to guarantee the odor resistance of the sealing ring.
[0070] In some embodiments, the inorganic molecular sieve particles include one of a sodium-based molecular sieve, a potassium-based molecular sieve, and a calcium-based molecular sieve. Here, one of the sodium-based molecular sieve, the potassium-based molecular sieve, and the calcium-based molecular sieve means that the inorganic molecular sieve particles can be independently selected from the sodium-based molecular sieve, the potassium-based molecular sieve, or the calcium-based molecular sieve. These molecular sieve materials have excellent adsorption performance and are easy to clean, which can further improve the odor resistance of the sealing ring during use. Moreover, the types of molecular sieves that can be used are diversified, and multiple types of sealing rings can be manufactured to adapt to more diversified sealing requirements.
[0071] In some embodiments, the particle size of the inorganic molecular sieve particles is 2 microns-5 microns, so that the inorganic particles can be uniformly dispersed in the elastic base layer while not significantly affecting the elasticity and strength of the sealing ring.
[0072] In some embodiments, the pore size of the inorganic molecular sieve particles is In this way, specific size odor molecules can be effectively adsorbed, while avoiding the adsorption of other beneficial substances to cause adverse effects.
[0073] According to the second aspect of the present application, a container is provided, wherein the container comprises a container body 20 and a container cover 30 arranged at the mouth of the container body 20, and the container cover 30 is provided with the sealing ring.
[0074] Specifically, the container is a cup or a kettle, and the sealing ring is arranged in a sealing ring accommodating groove of the container cover 30 or on the outer side surface of an inner plug of the container cover 30.
[0075] Hereinafter, the cup will be taken as an example for specific description.
[0076] In the case where the sealing ring is arranged on the outer side surface of the inner plug of the cup cover, referring to Figure 1 and Figure 2 , the sealing ring comprises a first base layer 11 and a second base layer 12, and the second base layer 12 is connected to the radial inner side of the first base layer 11. When the sealing ring is arranged on the outer side surface of the inner plug of the cup cover, the second base layer 12 is in contact with the outer side of the inner plug, the radial outer side surface of the first base layer 11 is in contact with the cup body, and under the action of external force, the sealing ring is sealed between the cup cover and the cup body.
[0077] Referring to Figure 3 and Figure 4 , the sealing ring comprises a first base layer 11 and a second base layer 12, and the second base layer 12 is connected to the first base layer 11. In the case where the sealing ring is arranged in the accommodating groove of the cup cover, the second base layer 12 is in contact with the bottom surface of the accommodating groove, the lower surface of the first base layer 11 is in contact with the cup body, and under the action of external force, the sealing ring is sealed between the cup cover and the cup body.
[0078] Although the embodiments of the present application have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. However, it should be understood that these modifications and variations will still fall within the spirit and scope of the embodiments of the present application as defined by the claims.
