[0002] In daily life, we often encounter situations where bottles or cans, once opened, are difficult to reseal. This necessitates that these products be used as soon as possible after opening to prevent spoilage. To address this, existing technologies, such as the Chinese utility model patent with patent number ZL201420495368.5, disclose a reusable sealing cap for aluminum cans. This cap includes a cap body with a first annular groove on the inner wall of the cap body that mates with the flange at the top of the can. A rubber gasket is located on the top inner wall of the cap body, corresponding to the can opening, to seal the can opening. A second annular groove is located on the outer wall of the rubber gasket, circumferentially aligned with the edge of the can opening. This reusable cap prevents spoilage of the remaining beverage or contamination from dust after the can is opened, thus avoiding waste. It also prevents spills and staining of clothing.

[0003] However, the aforementioned sealing caps still suffer from low utilization and poor ease of use. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] As mentioned in the background section, the sealing cap is only suitable for one size of aluminum can. Currently, even for a 330ml can of cola, there are two types: a regular short can and a tall, narrow can, each with a different neck size. In addition, there are other neck sizes for aluminum cans. To meet the secondary sealing needs of cans with different neck sizes, a corresponding number of sealing caps are required. Furthermore, besides aluminum cans, glass bottles for wine or beer are also difficult to seal after opening, so in addition to the sealing caps mentioned above, sealing plugs are also needed. However, the frequency of secondary sealing for bottles and cans is not high for ordinary users. If multiple sealing caps and plugs are provided, the overall utilization rate will inevitably be low, and choosing the appropriate sealing cap from among several options will also affect the convenience of use. Example 1

[0027] Therefore, such as Figure 1 As shown, this embodiment provides a multifunctional sealing bottle cap, including a main cap body 1, sealing rings 2, and a sealing plug 3, all integrally molded and made of food-grade silicone material. The main cap body 1 is a circular planar structure with a first side 101 and a second side 102 facing away from each other. Two concentric sealing rings 2 are provided on the first side 101. The two sealing rings 2 have different diameters and a gap between them to prevent the elasticity of one sealing ring from being affected by the other. The sealing plug 3 is located at the center of the first side 101. Due to the large difference in diameter, there is a large distance between the sealing plug 3 and the sealing rings 2, so they do not affect each other radially. To prevent the sealing plug 3 from pressing against the top surface of the can during use, affecting the fit depth between the sealing rings 2 and the bottle opening, the height of the sealing plug 3 needs to be less than or equal to the height of any sealing ring 2 in the sealing plug height direction. Therefore, the height of the sealing plug 3 is low, which can meet short-term temporary sealing needs. Of course, the sealing plug 3 can also be placed on the second side 102, and its height increased, such as... Figure 2 As shown, this is to meet the sealing requirements for a longer period of time.

[0028] Therefore, in this embodiment, two diameter sealing rings 2 and sealing plugs 3 are systematically integrated onto the same main cap body 1. When there is a need for secondary sealing of bottles and jars, a specific part of this sealing cap can be selected for the sealing operation. Thus, this sealing cap can meet the sealing needs of various bottles and jars, improving its utilization rate; it also avoids the need to choose from multiple sealing caps, improving convenience during use. Of course, according to actual needs, sealing rings of more diameter specifications can be set on the main cap body.

[0029] In addition, existing technologies generally achieve sealing by placing a sealing ring around the outer edge of the bottle opening. To improve the sealing effect, this embodiment provides an annular sealing groove 21 at the end of the sealing ring 2 facing away from the main cap 1. During use, the bottle opening is inserted into the annular sealing groove 21 to achieve a seal, thus doubling the sealing length and significantly improving the sealing effect. To improve the smoothness of insertion into the annular sealing groove 21, a first chamfer structure 211 is provided at the opening of the annular sealing groove 21. Furthermore, to prevent the sealing ring 2 from falling off the bottle opening, an annular limiting groove 212 is provided on the outer side wall of the annular sealing groove 21. Since the upper end of a can typically uses an outward-flaring process, a flange structure is formed on the outer edge of the can opening. The annular limiting groove 212, in conjunction with the flange structure, effectively limits the sealing ring in the height direction.

[0030] To facilitate the insertion of the sealing plug into the bottle opening, the end of the sealing plug 3 facing away from the main cap 1 is provided with a second chamfer structure 31. Example 2

[0031] like Figure 3 As shown, this embodiment considers the possibility of accidental loss of the screw cap on a plastic bottle. A spare screw cap 4 is integrated on the second side 102 of the main cap body 1 to address the sealing requirements in such cases. The screw cap 4 is specifically positioned at the center of the second side 102 to ensure the balance of the entire cap on the plastic bottle and prevent the bottle from tipping over. Therefore, the sealing plug 3 needs to be positioned at the center of the first side 101, i.e., opposite to the screw cap 4. In this way, the sealing plug 3 also provides an effective force application point for the operation of the screw cap 4, allowing the screw cap 4 to be tightened and loosened by rotating the sealing plug 3. Of course, the rotation of the sealing plug 3 can also be used as a pre-tightening operation of the screw cap 4. Finally, the screw cap 4 can be tightened by pressing down on the main cap body 1, with force applied through the main cap body 1 to ensure the tightness and to avoid excessive stress on the connection between the sealing plug 3 and the main cap body 1, which could affect its service life.

[0032] Since the threaded cap 4 is generally made of plastic, which is different from the silicone material of the main cap, it cannot be integrally molded with the main cap 1. The two can be connected by adhesive bonding. In order to improve the stability of the adhesive bonding, an installation sleeve 11 is provided on the second side 102. The installation sleeve 11 is integrally molded with the main cap 1, and the threaded cap 4 is glued inside the installation sleeve 11. In this way, the bottom and side surfaces of the threaded cap 4 are connected to the main cap 1, resulting in higher stability. Example 3

[0033] As mentioned in Example 1, to meet more sealing requirements, seals with more diameter specifications can be provided. However, the sealing ring has a certain width in the radial direction, so if some sealing rings with similar diameters are placed on the same side, they will interfere with each other. Therefore, as... Figure 4As shown, in this embodiment, sealing rings 2 with similar diameters are respectively disposed on the first side 101 and the second side 102 to avoid mutual interference. For example, if there are four sizes of sealing rings: 43mm, 48mm, 53mm, and 58mm, then two sealing rings of 48mm and 58mm can be disposed on the first side 101, while two sealing rings of 43mm and 53mm can be disposed on the second side 102.

[0034] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model. Furthermore, the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
