Description

Technical Field

[0001] This utility model relates to a sealing element, and more particularly to a sealing bottle cap and packaging bottle. Background Technology

[0002] Currently, using an inner stopper to enhance the seal at the bottle opening is common in bottle cap sealing. This method is simple in structure and easy to mold. However, the inner stopper seal requires an interference fit between the inner stopper and the inner wall of the bottle opening, resulting in significant friction when opening and tightening the cap. Users will notice a difference in the amount of force required, especially when the contents are carbonated beverages, where even greater force is needed to open. Therefore, there is an urgent need for a bottle cap that can both ensure a tight seal at the bottle opening and allow for easier opening and closing. Utility Model Content

[0003] The purpose of this utility model is to provide a sealing cap and packaging bottle to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A sealing bottle cap includes: a cap body with a bottom opening and an inner connecting structure inside the cap body; and a sealing plug including a connecting section, a deformable section, an outer support section, and a sealing section coaxially connected from the inside to the outside, wherein the connecting section is connected to the top side of the cap body, the sealing section is located at the top of the outer support section, and the deformable section, in its natural state, can move the sealing section away from the top side of the cap body and reduce the outer diameter of the outer support section; when the sealing section moves upward, it can cause the deformable section to elastically deform and increase the outer diameter of the outer support section.

[0006] This technical solution has at least the following beneficial effects: In use, the packaging bottle to be sealed is aligned with the cap, so that the bottle opening is inserted into the cap body through the bottom opening. At this time, the outer support section enters the packaging bottle from the bottle opening, causing the top of the bottle to abut against the sealing section, pushing the sealing section upwards to the top side of the cap body. As the sealing section moves upwards, it causes the deformation section to elastically deform, increasing the outer diameter of the outer support section until it abuts and presses tightly against the inner side of the bottle opening, thus sealing the bottle opening tightly. By utilizing the internal connecting structure inside the cap body to connect with the pre-set structure on the packaging bottle, the packaging bottle and cap body can be sealed together. The caps are fixed together. When it is necessary to remove the cap from the bottle, the bottle is moved downward relative to the cap. At this time, the deformed section elastically recovers, which can drive the sealing section away from the top side of the cap. This reduces the outer diameter of the outer support section so that it moves away from the inside of the bottle opening, releasing the seal on the bottle opening. It also separates the inner connecting structure inside the cap from the pre-set structure of the bottle. Thus, when opening and closing the cap, the outer diameter of the outer support section can be increased to ensure the seal with the bottle opening, and the outer diameter of the outer support section can be reduced to reduce the friction force when it leaves the bottle opening. This makes the operation easier and better balances the sealing performance and ease of operation when using the cap.

[0007] As a further improvement to the above technical solution, the deformable segment is inclined downward in a direction away from the connecting segment in its natural state.

[0008] As a further improvement to the above technical solution, the outer side of the outer support section is provided with a guide surface, a pressing surface and a transition surface from bottom to top. The guide surface is inclined upward in the direction away from the connecting section, the pressing surface is vertically upward, the pressing surface is directly opposite the end position of the deformable section connected to the outer support section, and the transition surface is inclined upward in the direction close to the connecting section.

[0009] As a further improvement to the above technical solution, a connecting post is connected to the top side of the inner body of the cover, and the connecting segment is sleeved on the outside of the connecting post.

[0010] As a further improvement to the above technical solution, an annular groove is provided on the outer side of the top of the connecting column, and an annular protrusion is provided on the connecting section corresponding to the position of the annular groove, with the annular protrusion fitting into the annular groove.

[0011] As a further improvement to the above technical solution, the connecting column is a hollow structure.

[0012] As a further improvement to the above technical solution, the outer side of the blocking section is provided with a downwardly protruding annular rim.

[0013] As a further improvement to the above technical solution, the internal connection structure includes an internal thread formed on the inner side of the cover body.

[0014] As a further improvement to the above technical solution, the present invention also includes a safety ring, wherein the top side of the safety ring is connected to the bottom side of the cover body by a connecting piece and a plurality of easily broken ribs.

[0015] A packaging bottle includes a bottle body and the aforementioned sealing cap. The bottle body has an external connecting structure located on the outside of its opening that mates with the internal connecting structure. The top of the bottle body presses the sealing section against the top side of the cap body, and the external supporting section abuts against the inside of the bottle opening of the bottle body.

[0016] This technical solution has at least the following beneficial effects: When connecting the bottle body with the aforementioned sealing cap, the bottle mouth is inserted into the cap body through the lower opening on the bottom side. At this time, the outer support section enters the bottle body from the bottle mouth, and the top of the bottle body abuts against the sealing section. The sealing section is pushed upward to the top side of the cap body. At this time, the outer diameter of the outer support section can be increased so that the outer support section can be pressed tightly against the inside of the bottle mouth to ensure the sealing performance with the bottle mouth. When the bottle mouth is removed from the cap body, the outer diameter of the outer support section can be reduced so that the outer support section is removed from the inside of the bottle mouth, reducing the friction force encountered when removing the bottle mouth. This makes the operation more labor-saving and better balances the sealing performance and ease of operation when using the sealing cap.

[0027] Reference Figure 1 , Figure 2 and Figure 3A sealing bottle cap includes a cap body 100 and a sealing plug. The cap body 100 has an internal cavity and a lower opening on its bottom side, which communicates with the internal cavity. An internal connecting structure 110 is provided on the inner side of the cap body 100. The sealing plug includes a connecting section 210, a deformable section 220, an outer support section 230, and a sealing section 240, which are coaxially connected from the inside to the outside. Specifically, the deformable section 220 is arranged around the outside of the connecting section 210, the outer support section 230 is arranged around the outside of the deformable section 220, and the sealing section 240 is arranged around the outside of the outer support section 230. The connecting section 210 is connected to the inner top side of the cap body 100. The sealing section 240 is located at the top of the outer support section 230. In its natural state, the deformable section 220 can drive the sealing section 240 away from the inner top side of the cover 100 and reduce the outer diameter of the outer support section 230. When the sealing section 240 moves upward, it can drive the deformable section 220 to elastically deform and increase the outer diameter of the outer support section 230. Naturally, the deformable section 220 and the outer support section 230 are made of elastic material to achieve elastic deformation. For example, the deformable section 220 and the outer support section 230 can be made of rubber. In practical applications, the connecting section 210, the deformable section 220, the outer support section 230 and the sealing section 240 are integrally formed structures.

[0028] As described above, in use, the packaging bottle to be sealed is aligned with the cap 100, so that the bottle opening is inserted into the cap 100 through the lower opening on the bottom side. At this time, the outer support section 230 enters the packaging bottle from the bottle opening, and the top of the packaging bottle abuts against the sealing section 240, pushing the sealing section 240 upward to the top side inside the cap 100. When the sealing section 240 moves upward, it can drive the deformation section 220 to elastically deform, so that the outer diameter of the outer support section 230 increases to abut against the inner side of the bottle opening, tightly sealing the bottle opening. By using the inner connecting structure 110 on the inner side of the cap 100 to connect with the preset structure on the packaging bottle, the mutual sealing of the packaging bottle and the cap 100 can be achieved. When the cap 100 needs to be removed from the bottle, the bottle is moved downward relative to the cap 100. At this time, the deformable section 220 elastically recovers, which can drive the sealing section 240 away from the inner top side of the cap 100. This causes the outer diameter of the outer support section 230 to shrink so that it leaves the inner side of the bottle opening, releasing the seal on the bottle opening. It also causes the inner connecting structure 110 on the inner side of the cap 100 to separate from the preset structure of the bottle. Thus, when the cap 100 is opened and closed, the outer diameter of the outer support section 230 can be increased to ensure the seal with the bottle opening, and the outer diameter of the outer support section 230 can be reduced to reduce the frictional force encountered when leaving the bottle opening. This makes the operation more effortless and better balances the sealing performance and ease of operation when using the cap.

[0029] The deformable section 220 is mainly used to drive the sealing section 240 downward away from the inner top side of the cover 100 in its natural state, and to push the outer support section 230 outward when the sealing section 240 moves upward. It has various structural forms. In this embodiment, the deformable section 220 is inclined downward in its natural state, away from the connecting section 210. When the deformable section 220 is in its natural state, due to its inclined setting, it does not exert an outward force on the outer support section 230. When the sealing section 240 moves upward, it drives the connecting section 210 to deform from an inclined state to a horizontal state. At this time, the outer diameter of the connecting section 210 gradually increases, applying a gradually outward force to the outer support section 230, causing the outer support section 230 to expand, thereby increasing its outer diameter.

[0030] The outer surface of the outer support section 230 can be a vertical plane. In order to improve the sealing effect of the outer support section 230 on the inner side of the bottle mouth, in this embodiment, the outer side of the outer support section 230 is provided with a guide surface 231, a pressing surface 232 and a transition surface 233 from bottom to top. The guide surface 231 is inclined upward in the direction away from the connecting section 210. The pressing surface 232 is vertically upward and is directly opposite the end position of the deformable section 220 connected to the outer support section 230. The transition surface 233 is inclined upward in the direction close to the connecting section 210. Since the guide surface 231 is inclined upward along the direction away from the connecting section 210, the guide surface 231 forms a cylindrical structure that is larger at the top and smaller at the bottom. This allows the guide surface 231 to be easily inserted into the bottle mouth, and increases the thickness of the outer support section 230 at the position corresponding to the pressing surface 232. When the deformation section 220 pushes it outward, the entire pressing surface 232 can press against the inside of the bottle mouth, playing the main role of pressing and sealing the bottle mouth. The transition surface 233 forms a cylindrical structure that gradually narrows upward, reducing the thickness of the outer support section 230 above the pressing surface 232.

[0031] The connecting segment 210 can be fixed to the inner top side of the cover 100 by means of plugging or bonding. In this embodiment, a connecting post 120 is connected to the inner top side of the cover 100, and the connecting segment 210 is sleeved on the outside of the connecting post 120. When connecting the sealing plug to the cover 100, it is only necessary to sleeve the connecting segment 210 on the outside of the connecting post 120, thus enabling the sealing plug to be quickly installed and connected to the cover 100.

[0032] When the connecting segment 210 is fitted onto the outside of the connecting post 120, the friction between the two can be used to fix the connecting segment 210. To further improve the stability of the connection and positioning of the connecting segment 210 and the connecting post 120, in this embodiment, an annular groove is provided on the outer top of the connecting post 120, and an annular protrusion 211 is provided on the connecting segment 210 corresponding to the position of the annular groove. The annular protrusion 211 is fitted into the annular groove. When the connecting segment 210 is fitted onto the outside of the connecting post 120, the annular protrusion 211 of the connecting segment 210 can be expanded outward to increase the internal space, and then fitted onto the outer bottom of the connecting post 120. When the annular protrusion 211 moves to the annular groove, the annular protrusion 211 elastically recovers and fits into the annular groove. In this way, the fit and positioning of the annular protrusion 211 and the annular groove can effectively prevent the connecting segment 210 from falling off the outside of the connecting post 120, making the sealing plug more firmly connected inside the cover 100.

[0033] To better control the weight of the cover 100, in this embodiment, the connecting post 120 is a hollow structure. The hollow connecting post 120 can reduce the overall weight of the cover 100, thereby better controlling the overall cost.

[0034] When the bottle neck abuts against the sealing section 240, the tight fit of the sealing section 240 against the bottle neck seals the bottle neck. To further improve the sealing effect, in this embodiment, a downwardly protruding annular rim 241 is provided on the outer side of the sealing section 240. At this time, an area for sealing the bottle neck is formed between the annular rim 241 and the outer support section 230. When the bottle neck is inserted into this area, the outer support section 230 abuts against the inner side of the bottle neck, and the annular rim 241 abuts against the outer side of the bottle neck, pressing against the bottle neck in multiple directions, thus greatly improving the sealing effect at the bottle neck.

[0035] The inner connecting structure 110 is mainly used to connect and fix the cap 100 to the packaging bottle. It has various structural forms. For example, the inner connecting structure 110 includes a slot formed inside the cap 100. In this case, the packaging bottle has a buckle. After the packaging bottle and the cap 100 are aligned, the buckle and the slot connect to each other, thereby fixing the packaging bottle and the cap 100 together. In this embodiment, the inner connecting structure 110 includes an internal thread formed inside the cap 100. The outer side of the packaging bottle has an external thread. The mutual engagement of the internal and external threads allows for a gradual locking connection between the cap 100 and the packaging bottle, resulting in a stable connection structure.

[0036] This utility model also includes a safety ring 300. The top side of the safety ring 300 is connected to the bottom side of the cap 100 by a connecting piece 310 and multiple easy-break ribs 320. In practical applications, multiple easy-break ribs 320 are arranged around the cap 100. The safety ring 300 is used to connect to the outside of the bottle opening. In use, rotating the cap 100 causes the multiple easy-break ribs 320 between the cap 100 and the safety ring 300 to break, thus allowing the cap 100 to be opened from the bottle opening. At this time, the connecting piece 310 connects between the cap 100 and the safety ring 300 to prevent the cap 100 from completely separating from the safety ring 300.

[0037] In practical applications, in order to facilitate the rotation of the cover 100, multiple friction textures can be set on the outer side of the cover 100, thereby increasing the friction applied to the outer side of the cover 100 and improving the ease of operation.

[0038] A packaging bottle includes a bottle body and the aforementioned sealing cap. The bottle body has an external connecting structure located on the outside of its bottle opening that is connected to the internal connecting structure 110. The top of the bottle body presses the sealing section 240 against the inner top side of the cap 100, and the external support section 230 abuts against the inner side of the bottle opening of the bottle body.

[0039] When connecting the bottle body to the sealing cap described above, insert the bottle mouth into the cap body 100 through the lower opening on the bottom side of the cap body 100. At this time, the outer support section 230 enters the bottle body from the bottle mouth, and the top of the bottle body abuts against the sealing section 240. Push the sealing section 240 upward to the top side inside the cap body 100. At this time, the outer diameter of the outer support section 230 can be increased so that the outer support section 230 presses tightly against the inside of the bottle mouth to ensure the sealing performance with the bottle mouth. When the bottle mouth is removed from the cap body 100, the outer diameter of the outer support section 230 can be reduced so that the outer support section 230 leaves the inside of the bottle mouth, reducing the friction force encountered when removing the bottle mouth, thereby making the operation more effortless and better balancing the sealing performance and ease of operation when using the sealing cap.
