Existing sealing caps on glass bottles and jars are usually made of glass, which is relatively heavy. Furthermore, glass sealing caps are generally secured with steel ring clips. A sealing groove is provided at the mouth of the glass bottle or jar to install the clipping steel ring. However, clip-on sealing caps are difficult to fasten and open, and when the clips are tight, they can easily spring back when opening or fastening. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lightweight sealing cover that is easy to open and close.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sealing cap, including a cap body, at least two buckles, and a mounting protrusion ring. Each buckle is fixedly disposed at intervals on the side of the cap body, and each buckle protrudes towards the side near the bottle opening. The buckles are made of elastic material, and a locking block is protruding on the inner side of the buckle. The locking block is locked in the sealing groove of the bottle opening. The mounting protrusion ring is disposed on the side of the cap body near the bottle opening, and a sealing mounting part is formed between the mounting protrusion ring and the side of the cap body. The bottle opening is sealed and locked in the sealing mounting part. At least one air inlet is opened on the mounting protrusion ring, and the air inlet is disposed corresponding to the buckle.
[0005] Preferably, a sealing ring is fixedly provided inside the sealing mounting part.
[0006] Preferably, the outer diameter of the end of the mounting ring closest to the cover body is larger than the outer diameter of the other end of the mounting ring, and a plurality of fixing ribs are provided at intervals at the other end of the mounting ring, the outer diameter of the plurality of fixing ribs being the same as the outer diameter of the end of the mounting ring.
[0007] Preferably, the buckle is inclined, with one end of the buckle integrally formed with the cover body and the other end of the buckle inclined outward from the cover body.
[0008] Preferably, a ring of overlapping protrusions is provided on the side of the cap body away from the bottle opening.
[0009] Preferably, a stacking groove is recessed in the middle of the side of the cap body away from the bottle opening.
[0010] Preferably, the cover body, buckle, and mounting ring are all integrally formed and made of PP material.
[0011] Preferably, the end of the card block furthest from the cover body is provided with an arc-shaped surface.
[0012] Preferably, the mounting ring has an inclined angle at its edge near the air inlet, and the inclined angle is located at the other end where the mounting ring connects to the cover body, with the height at the edge of the mounting ring being the minimum.
[0013] Preferably, two buckles are fixedly provided on the cover body, and the two buckles are symmetrically arranged along the radial direction of the cover body. Two air inlets are also correspondingly provided on the mounting protrusion ring.
[0014] Compared with existing technologies, the above technical solution has the following beneficial effects:
[0015] 1. This utility model has a buckle fixedly connected to the cap body, and a locking block is provided on the inner side of the buckle. The locking block is locked in the sealing groove at the original bottle mouth, forming a sealing installation part between the mounting protrusion ring and the side of the cap body. The bottle mouth or can mouth is sealed in the sealing installation part to ensure the sealing performance of the cap. In addition, an air inlet is provided on the mounting protrusion ring at the corresponding position of the buckle. When the user opens the buckle, air can enter the bottle or can through the air inlet at the first time, making subsequent bottle opening more convenient and effortless.
[0016] 2. Install a sealing ring inside the sealing installation part to increase the sealing reliability, and set up an air inlet to facilitate the user to replace the sealing ring.
[0017] 3. Because the molds need to be polished during the production of bottles or cans, there will be a certain error in the inner diameter of the bottle or can opening in each batch. Therefore, the sealing cap needs to have a certain degree of tolerance while ensuring a seal. Thus, the outer diameter of the end of the mounting ring closest to the cap body is set to be larger than the outer diameter of the other end. Several fixing ribs are set at intervals on the other end of the mounting ring. The outer diameter of the outer circle of the fixing ribs is the same as the outer diameter of the mounting ring. This setting allows the fixing ribs to be fixedly clamped to the inner wall of the bottle or can opening. At the same time, the positions without fixing ribs can be slightly adjusted, so that the sealing cap has a certain degree of tolerance and can better adapt to the bottle.
[0018] 4. The upper end of the sealing cap is provided with a stacking protrusion and a stacking groove. The stacking protrusion and the stacking groove are both set to correspond to the bottom of the bottle, so as to facilitate the connection with the bottom protrusion (foot ring) of the bottle or can. When the bottle or can with the sealing cap is stacked up and down, it is more stable and less likely to tip over.
[0019] 5. The buckle is made of elastic material. The sealing cover can be opened and closed by directly prying it open from the end of the buckle outward or pressing it inward. The end of the buckle away from the cover body is set as an arc-shaped surface to facilitate the buckle to be locked in the sealing groove.
[0020] 6. The mounting ring has an inclined angle at the edge near the air inlet, so that the mounting ring has no obvious sharp edges, which facilitates the fastening of the sealing cap to the bottle or can.
[0021] 7. The main body of the cover, the buckle, and the mounting ring are all integrally molded and made of PP material, making the sealing cover lighter and easier to use. Attached Figure Description

[0030] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-7 The present invention will be further described below.
[0031] like Figure 1As shown, a sealing cap of this utility model includes a cap body 1, at least two buckles 4, and a mounting protrusion 2. In this embodiment, the sealing cap 11 is fastened to a glass bottle 12. Each buckle 4 is fixedly arranged at intervals on the side of the cap body 1, and each buckle 4 protrudes towards the side near the bottle opening. The buckles 4 are made of elastic material, and a locking block 5 protrudes from the inner side of the buckle 4. The glass bottle 12, which originally used a steel ring buckle, has a sealing groove 13 at the bottle opening for placing the steel ring. In this embodiment, there is no need to change the specifications of the glass bottle 13. The locking block 5 is locked in the sealing groove 13 at the bottle opening for installation. A raised ring 2 is provided on the side of the cap body 1 near the bottle mouth, forming a sealing mounting part 6 between the mounting raised ring 2 and the side of the cap body 1. The bottle mouth seal is locked in the sealing mounting part 6. To further increase the sealing reliability, a sealing ring is fixedly provided in the sealing mounting part 6. The sealing ring is pressed against the end of the bottle mouth. At least one air inlet 7 is provided on the mounting raised ring 2. The air inlet 7 is provided corresponding to the buckle 4. When the user opens the buckle 4, air can enter the bottle through the air inlet 7 at the first time, making it more convenient and effortless to open the bottle later. The air inlet 7 also makes it convenient for the user to replace the sealing ring.
[0032] like Figure 2 As shown, during the production of glass bottles 12, the mold needs to be polished after each batch of glass bottles 12 is produced. Although the wear from polishing is very low, there will still be a certain error in the inner diameter of the bottle mouth of each batch of glass bottles 12. Therefore, the sealing cap 11 needs to have a certain degree of tolerance while ensuring a seal. In this embodiment, the outer diameter of the end of the mounting ring 2 near the cap body 1 is larger than the outer diameter of the other end of the mounting ring 2. Several fixing ribs 3 are provided at intervals at the other end of the mounting ring 2. The outer diameter of the outer circle of the fixing ribs 3 is the same as the outer diameter of the end of the mounting ring 2. When the sealing cap 11 is fastened, the fixing ribs 3 are fixedly clamped on the inner wall of the bottle mouth, and the position without fixing ribs 3 forms a tolerance groove 8. There is a certain gap between the tolerance groove 8 and the inner wall of the bottle mouth. The tolerance groove 8 can be used to make a small adjustment. Therefore, the sealing cap 11 can have a certain degree of tolerance and better adapt to the glass bottle 12.
[0033] like Figures 3-5As shown, in this embodiment, two buckles 4 are fixedly provided on the cover body 1. The two buckles 4 are symmetrically arranged radially along the cover body 1. Two air inlets 7 are also correspondingly provided on the mounting ring 2, and the two air inlets 7 are respectively provided for the two buckles 4. In order to facilitate the fastening or opening of the sealing cover 11, the buckles 4 are inclined, and one end of the buckle 4 is integrally set with the cover body 1. The other end of the buckle 4 is inclined to the outside of the cover body 1. At the same time, the end of the locking block 5 away from the cover body 1 is set with an arc-shaped surface. When opening or fastening the sealing cover 11, the user operates by operating the lower end of the buckle 4 to open it outward or press it inward to complete the opening and closing of the sealing cover 11. The lower end of the locking block 4 is arc-shaped, which makes it easier and smoother to fasten the locking block 4 into the sealing groove 13 or to remove the locking block 4 from the sealing groove 13.
[0034] The mounting ring 2 has an inclined angle at its edge near the air inlet 7. The inclined angle is located at the other end where the mounting ring 2 connects to the cap body 1. The height of the mounting ring 2 is the smallest at its edge. The inclined angle makes the mounting ring 2 free of sharp edges, which facilitates the fastening of the sealing cap 11 and the glass bottle 12.
[0035] In this embodiment, the cap body 1, the buckle 4, and the mounting ring 2 are all integrally formed and made of PP material, making the sealing cap 11 lighter and more elastic, and the overall weight of the glass bottle 12 lighter, making it easier to use. A stacking protrusion 9 is provided on the side of the cap body 1 away from the bottle opening, and a stacking groove 10 is provided in the middle of the side of the cap body 1 away from the bottle opening. The stacking protrusion 9 and the stacking groove 10 are both provided corresponding to the bottom of the bottle, which facilitates the connection with the protrusion (ring foot) on the bottom surface of the bottle. When the glass bottle 12 with the sealing cap 11 is stacked, it is more stable and less likely to tip over.
[0036] like Figures 6-7 Two rings of buckle protrusions 14 are provided at the mouth of the glass bottle 12, forming a sealing groove 13 between the two buckle protrusions 14. The sealing groove 13 was originally used to place the steel ring. In this utility model, the sealing groove 13 is utilized. When the sealing cap 11 is fastened, the bottle mouth is locked in the sealing installation part 6, and then the two buckles 4 are fastened inward, so that the locking block 5 is opened in the sealing groove 13. This fixes the sealing cap 11 to the cooperation between the sealing installation part 6 and the sealing ring, ensuring the sealing reliability of the glass bottle 12. When the sealing cap 11 is opened, the buckles 4 are pried outward, so that the locking block 5 is dislodged from the sealing groove 13. At the same time, outside air enters into the glass bottle 12 through the air inlet 7, balancing the air pressure inside the glass bottle 12 with the outside air, making the sealing cap 11 easier to open.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
