Description

Technical Field

[0001] This utility model belongs to the technical field of container sealing equipment, specifically relating to a sealing structure and a bottle. Background Technology

[0002] Bottles are frequently used containers in daily life, often for holding liquids. Because liquids are fluid, a seal between the bottle body and the cap is often necessary. Currently, there are two main sealing methods on the market: One is the end-face sealing method, where a sealing gasket is placed on the inner end face of the cap. When the bottle and cap are tightened, the end face of the bottle opening presses against the sealing gasket, causing it to deform and thus achieving a seal. However, because this method involves tightening while rotating, friction occurs directly between the bottle opening and the sealing gasket, which can easily damage the gasket with repeated use, leading to seal failure. The second method is the radial sealing method, where a sealing ring is fitted on the side of the bottle. As the cap is tightened, the sealing ring is compressed and deformed, achieving a seal. However, because the sealing ring constantly rubs against the inner side of the cap during tightening, it is difficult to tighten or loosen, and repeated use can easily damage the sealing ring, leading to seal failure. Utility Model Content

[0003] In view of this, in order to solve the problems in the prior art, the first objective of this utility model is to propose a sealing structure. The technical problem to be solved is: how to prevent the sealing ring from wearing out and improve the service life of the sealing ring.

[0004] This utility model solves the above problems through the following technical means:

[0005] A sealing structure is installed on a bottle, the bottle including a bottle body and a bottle cap, the bottle cap being threadedly connected to the outer surface of the bottle opening of the bottle body;

[0006] The sealing structure includes:

[0007] A sealing ring, wherein a sealing part is protruding on the outer side of the sealing ring, and a slot is provided between the sealing ring and the sealing part, and the upper end of the bottle mouth is inserted into the slot;

[0008] A sealing ring is fitted onto the upper end of the bottle opening, and the outer diameter of the sealing ring is smaller than the outer diameter of the sealing part.

[0009] The outer diameter of the sealing ring in this sealing structure is smaller than the outer diameter of the sealing part. When the bottle cap is closed on the bottle mouth, the inner side of the bottle cap is in direct contact with the outer side of the sealing part, but not with the outer side of the sealing ring. When the bottle cap is tightened to the bottle body, the bottle cap will not squeeze the sealing ring. The sealing part plays a good protective role for the sealing ring, effectively preventing wear on the sealing ring and greatly improving the service life of the sealing ring.

[0010] In one of the sealing structures described above, the upper end of the bottle opening is provided with a plug-in portion, which is inserted into the slot, and the sealing ring is fitted onto the plug-in portion.

[0011] In one of the sealing structures described above, the insertion part has a first inclined surface, and the slot has a second inclined surface. The first inclined surface and the second inclined surface cooperate to allow the insertion part to be inserted into the slot.

[0012] In one of the sealing structures described above, the connection between the bottle mouth and the insertion part has a stepped portion, the sealing ring is located between the sealing part and the stepped portion, and the outer diameter of the sealing ring is smaller than the outer diameter of the sealing part and the stepped portion.

[0013] In the aforementioned sealing structure, the connection between the sealing ring and the insertion portion and the stepped portion is an interference fit.

[0014] In one of the sealing structures described above, a limiting part is provided on the inner side of the insertion part, and a protrusion is provided on the outer side of the sealing ring. The protrusion cooperates with the limiting part to limit the sealing ring by the bottle mouth.

[0015] In one of the sealing structures described above, a plurality of guide blocks are provided on the sealing part, and the plurality of guide blocks are evenly arranged on the outer side surface of the sealing part.

[0016] In one of the sealing structures described above, the sealing ring is an O-ring rubber seal.

[0017] The second objective of this utility model is to provide a bottle comprising:

[0018] Bottle body;

[0019] A bottle cap, which is threadedly connected to the bottle body;

[0020] The aforementioned sealing structure is installed on the bottle opening of the bottle body.

[0021] In one of the aforementioned bottle types, the outer surface of the bottle opening is provided with an external thread, and the inner surface of the bottle cap is provided with an internal thread. The external thread and the internal thread cooperate to achieve a threaded connection between the bottle opening and the bottle cap.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] The sealing structure of this utility model, by having an outer diameter of the sealing ring smaller than the outer diameter of the sealing part, avoids the bottle cap squeezing the sealing ring. The sealing part plays a good protective role for the sealing ring, effectively preventing wear on the sealing ring and greatly improving the service life of the sealing ring.

[0024] The bottle of this utility model, through the above-mentioned sealing structure, provides good protection for the sealing ring, prevents wear on the sealing ring, improves the service life of the sealing ring, and thus ensures the sealing performance and service life of the bottle.

[0036] Currently, there are two main sealing methods on the market: One is end-face sealing, where a sealing gasket is placed on the inner end face of the cap. When the bottle and cap are tightened, the end face of the bottle opening presses against the sealing gasket, causing it to deform and thus achieving a seal. However, because this is a rotating and tightening method, friction occurs directly between the bottle opening and the sealing gasket, leading to damage after repeated use and sealing failure. The second method is radial sealing, where a sealing ring is fitted on the side of the bottle. As the cap is tightened, the sealing ring is compressed and deformed, achieving a seal. However, because the sealing ring constantly rubs against the inner side of the cap during tightening, it is difficult to tighten or untighten, and repeated use can damage the sealing ring, leading to sealing failure. Therefore, this invention provides a sealing structure and bottle to prevent wear on the sealing ring, improve its lifespan, and ensure the bottle's sealing effect.

[0037] Example 1:

[0038] like Figure 2-6As shown, this sealing structure is installed on a bottle, which includes a bottle body 1 and a bottle cap 2. The bottle cap 2 is threadedly connected to the outer side of the bottle mouth 11 of the bottle body 1. The sealing structure includes a sealing ring 3 and a sealing ring 4. A sealing part 31 is protruding on the outer side of the sealing ring 3. A slot 32 is provided between the sealing ring 3 and the sealing part 31. The upper end of the bottle mouth 11 is inserted into the slot 32. The sealing ring 4 is sleeved on the upper end of the bottle mouth 11. The outer diameter of the sealing ring 4 is smaller than the outer diameter of the sealing part 31.

[0039] In this embodiment, a sealing part 31 protrudes from the outer side of the sealing ring 3, and a slot 32 is provided between the sealing ring 3 and the sealing part 31. The upper end of the bottle mouth 11 is inserted into the slot 32, that is, the sealing ring 3 is installed to the upper end of the bottle mouth 11, thereby fixing the sealing ring 3 to the bottle mouth 11. The sealing ring 4 is sleeved on the upper end of the bottle mouth 11. It can be understood that when the bottle cap 2 is threadedly connected to the bottle mouth 11, that is, when the bottle cap 2 is closed on the bottle mouth 11, the sealing ring 4 provides a good seal for the connection between the bottle cap 2 and the bottle mouth 11, preventing the liquid in the bottle body 1 from overflowing from the connection between the bottle cap 2 and the bottle mouth 11. It should be noted that... The outer diameter of the sealing ring 4 refers to the maximum diameter of the sealing ring 4, and the outer diameter of the sealing part 31 refers to the maximum diameter of the sealing part 31. Since the outer diameter of the sealing ring 4 is smaller than the outer diameter of the sealing part 31, that is, the outermost edge of the sealing part 31 is outside the outermost edge of the sealing ring 4, when the bottle cap 2 is closed on the bottle mouth 11, the inner side of the bottle cap 2 is in direct contact with the outer side of the sealing part 31, but cannot be in direct contact with the outer side of the sealing ring 4. In other words, when the bottle cap 2 is tightened with the bottle body 1, the bottle cap 2 will not squeeze the sealing ring 4. The sealing part 31 plays a good protective role for the sealing ring 4, effectively preventing wear on the sealing ring 4 and greatly improving the service life of the sealing ring 4.

[0040] As can be seen, by making the outer diameter of the sealing ring 4 smaller than the outer diameter of the sealing part 31, the bottle cap 2 is prevented from squeezing the sealing ring 4. The sealing part 31 plays a good protective role for the sealing ring 4, effectively preventing wear on the sealing ring 4 and greatly improving the service life of the sealing ring 4.

[0041] like Figure 3 and 4 As shown, the upper end of the bottle mouth 11 is provided with a plug part 12, which is inserted into the slot 32, and the sealing ring 4 is sleeved on the plug part 12.

[0042] In this embodiment, the upper end of the bottle mouth 11 is provided with a plug part 12. The plug part 12 is inserted into the slot 32 to realize the installation and fixation between the sealing ring 3 and the bottle body 1. When the bottle cap 2 is tightened with the bottle body 1, the sealing part 31 plays a good protective role for the sealing ring 4, preventing wear on the sealing ring 4. The sealing ring 4 is fitted onto the plug part 12, realizing the sealing effect between the bottle mouth 11 and the bottle cap 2, effectively preventing liquid from overflowing from the gap between the bottle mouth 11 and the bottle cap 2.

[0043] like Figure 4 As shown, the plug-in portion 12 has a first inclined surface 121, and the slot 32 has a second inclined surface 321. The first inclined surface 121 and the second inclined surface 321 cooperate to allow the plug-in portion 12 to be inserted into the slot 32.

[0044] In this embodiment, the plug-in part 12 has a first inclined surface 121, and the slot 32 has a second inclined surface 321. The first inclined surface 121 and the second inclined surface 321 cooperate. When the plug-in part 12 is inserted into the slot 32, the first inclined surface 121 of the plug-in part 12 fits against the second inclined surface 321 of the slot 32, and the plug-in part 12 is inserted into the slot 32 along the second inclined surface 321 so that the plug-in part 12 can be smoothly inserted into the slot 32.

[0045] like Figure 4 As shown, the connection between the bottle mouth 11 and the insertion part 12 has a stepped part 13, and the sealing ring 4 is located between the sealing part 31 and the stepped part 13. The outer diameter of the sealing ring 4 is smaller than the outer diameter of the sealing part 31 and the stepped part 13.

[0046] In this embodiment, the connection between the bottle mouth 11 and the insertion part 12 has a stepped part 13. Specifically, the connection between the bottle mouth 11 and the first inclined surface 121 forms a stepped part 13. A receiving space 34 is formed between the stepped part 13 and the bottom of the sealing part 31. The sealing ring 4 is fitted onto the insertion part 12, and the sealing ring 4 is located in the receiving space 34 between the sealing part 31 and the stepped part 13. It can be understood that the outer diameter of the sealing part 31 is the same as the outer diameter of the stepped part 13. At this time, the outer diameter of the sealing ring 4 is smaller than the outer diameter of the sealing part 31 and the stepped part 13. When the insertion part 12 is inserted into the slot 32, the sealing part 31 and the stepped part 13 play a good protective role for the sealing ring 4, effectively preventing wear on the sealing ring 4.

[0047] like Figure 3 and 4 As shown, the connection between the sealing ring 4 and the insertion part 12 and the stepped part 13 is an interference fit.

[0048] In this embodiment, the sealing ring 4 is fitted onto the insertion part 12. As an example, the sealing ring 4 is an O-ring rubber sealing ring with good elasticity. The sealing ring 4 presses against the first inclined surface 121 and the stepped part 13 of the insertion part 12 so that the connection between the sealing ring 4 and the insertion part 12 and the stepped part 13 is interference fit. The upper end of the sealing ring 4 abuts against the lower end of the sealing part 31 to ensure the sealing effect between the bottle mouth 11 and the bottle cap 2 and prevent the body from overflowing from the gap between the bottle mouth 11 and the bottle cap 2.

[0049] As shown in Figures 3 and 4, a limiting part 122 is provided on the inner side of the insertion part 12, and a protrusion 33 is provided on the outer side of the sealing ring 3. The protrusion 33 cooperates with the limiting part 122 to limit the sealing ring 3 by the bottle mouth 11.

[0050] In this embodiment, a limiting part 122 is provided on the inner side of the insertion part 12. The limiting part 122 is a step formed between the inner side of the insertion part 12 and the inner side of the bottle mouth 11. It can be understood that the insertion part 12 is inserted into the slot 32 formed between the sealing ring 3 and the sealing part 31. That is, the sealing ring 3 is located on the inner side of the insertion part 12, and the sealing part 31 is located on the outer side of the insertion part 12. A protrusion 33 is provided on the outer side of the sealing ring 3. The protrusion 33 and the limiting part 122 can cooperate to limit the sealing ring 3 by the bottle mouth 11, effectively preventing the sealing ring 3 from falling off.

[0051] like Figure 5 and 6 As shown, the sealing part 31 is provided with a plurality of guide blocks 311, and the plurality of guide blocks 311 are evenly arranged on the outer side surface of the sealing part 31.

[0052] In this embodiment, a plurality of guide blocks 311 are evenly arranged on the outer side of the sealing part 31. When the bottle cap 2 is screwed into the bottle mouth 11, the inner side of the bottle cap 2 enters the bottle mouth 11 along the guide blocks 311, so that the bottle cap 2 can be screwed into the bottle mouth 11.

[0053] Example 2:

[0054] like Figure 1-3 As shown, this embodiment proposes a bottle, including a bottle body 1, a bottle cap 2, and the sealing structure described in Embodiment 1. The bottle cap 2 is threadedly connected to the bottle body 1; the sealing structure is installed on the bottle mouth 11 of the bottle body 1.

[0055] In this embodiment, using the sealing structure of Embodiment 1, the outer diameter of the sealing ring 4 is smaller than the outer diameter of the sealing part 31. When the bottle cap 2 is placed on the bottle mouth 11, the inner side of the bottle cap 2 directly contacts the outer side of the sealing part 31, but cannot directly contact the outer side of the sealing ring 4. When the bottle cap 2 is screwed onto the bottle body 1, the bottle cap 2 will not squeeze the sealing ring 4. The sealing part 31 plays a good protective role for the sealing ring 4, effectively preventing wear on the sealing ring 4, greatly improving the service life of the sealing ring 4, and thus ensuring the sealing of the bottle and the service life of the bottle.

[0056] like Figure 2 and 4 As shown, the outer side of the bottle mouth 11 is provided with an external thread 111, and the inner side of the bottle cap 2 is provided with an internal thread 21. The external thread 111 and the internal thread 21 are engaged to achieve a threaded connection between the bottle mouth 11 and the bottle cap 2.

[0057] In this embodiment, the outer side of the bottle mouth 11 is provided with an external thread 111, and the inner side of the bottle cap 2 is provided with an internal thread 21. The external thread 111 and the internal thread 21 cooperate to facilitate the screwing of the bottle cap 2 onto the bottle mouth 11.

[0058] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
