Description

Technical Field

[0001] This utility model relates to the field of sealing bottle technology, and in particular to a sealing bottle. Background Technology

[0002] In daily life, vacuum-sealed bottles (wide-mouth bottles, airtight jars, and storage containers) are widely used for storing food, medicine, electronic components, and other items that require air isolation for long-term preservation or to prevent moisture and oxidation. After vacuuming, the caps or seals of these bottles are held firmly together by the external atmospheric pressure, creating a negative pressure inside the bottle that causes the caps to be firmly "sucked" to the bottle body. Users, especially those with less strength or the elderly, often need to exert tremendous force to unscrew or pry open the caps, making the operation very strenuous and resulting in a poor user experience. During the process of forcibly opening the cap under immense pressure, excessive torque or prying force can easily damage the threaded structure of the cap due to excessive stress, or cause the entire cap or seal to warp, deform, or even crack due to uneven stress, rendering the cap or seal unable to seal properly even when closed onto the bottle. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a sealed bottle. The sealed bottle achieves the sealing of the bottle body and the bottle cap through the cooperation of the sealing plug body and the sealing step. At the same time, squeezing the sealing step can realize the gap conduction, thereby balancing the bottle body with the external air pressure and making it convenient to turn the bottle cap.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A sealed bottle includes: a bottle body and a bottle cap connected to the bottle body. The bottle cap has a first through hole, and an elastic sealing plug is disposed at the first through hole. The sealing plug includes a sealing plug body connected to the first through hole. A gap is formed between the sealing plug body and the wall of the first through hole. A sealing step is disposed at the top of the sealing plug body. The sealing step is located on the outside of the bottle cap. When a negative pressure is applied inside the bottle cap, the sealing step can seal the gap to form a sealing structure.

[0006] The sealing plug body is also provided with an indicator protruding to the top of the sealing plug body, and the indicator retracts into the sealing plug body when the bottle cap and the bottle body are under negative pressure.

[0007] The sealing plug body has a channel, the indicator is disposed on the wall of the channel, and part of the indicator extends from the channel to the top opening of the sealing plug body.

[0008] The indicator includes a connecting ring that can be connected to the wall of the channel. The connecting ring is provided with an arc-shaped connecting part, and an upwardly protruding indicator post is provided in the middle of the connecting part.

[0009] The sealing plug body is provided with a protruding ring at the top opening of the channel, and the protruding ring is provided with a second through hole for the indicator post to extend out.

[0010] The sealing plug body includes a sealing ring arranged in an annular shape, the sealing ring having the channel, the top of the sealing ring having the sealing step, and the bottom of the sealing ring having a stop portion that can prevent the sealing ring from disengaging from the first through hole, the stop portion being located inside the bottle cap.

[0011] The sealing step and the stop are spaced apart to form a space that allows the sealing ring to move up and down relative to the bottle cap.

[0012] The sealing plug is a one-piece molded structure.

[0013] The bottle cap is provided with a first sealing ring that can seal the bottle opening.

[0014] The bottle cap includes a cover plate that can seal the bottle opening, and an outer cover that can be connected to the bottle and press the cover plate tightly. The sealing plug is connected to the cover plate. The cover plate is provided with a second sealing ring. The outer cover is provided with a third through hole. The outer cover is also provided with a pressing ring that protrudes downward and presses against the cover plate.

[0015] Compared with existing technologies, this utility model has the following advantages:

[0016] 1. When using this utility model, the item is placed into the bottle, and then the bottle cap is placed on the bottle. The vacuum component is aligned with the first through hole on the bottle cap to create a vacuum in the bottle. The air inside the bottle is gradually extracted through the gap between the sealing plug body and the wall of the first through hole. After the vacuum is completed, a negative pressure is formed inside the bottle, which causes the sealing plug body to move downward. The sealing steps on the sealing plug body form a responsive sealing structure. When a negative pressure is generated inside the bottle, under the action of atmospheric pressure, the sealing steps will move downward and automatically press and seal the gap between the sealing steps and the inner wall of the first through hole, thus sealing the bottle cap and ensuring timely sealing.

[0017] 2. Moreover, when it is necessary to release the negative pressure, pull up the sealing step, causing the sealing step to move upward and separate from the gap, thereby allowing the gap to conduct the bottle body and the outside. At this time, the bottle body can release the negative pressure. After the negative pressure is released, the bottle cap can be easily unscrewed. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to embodiments:

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] Example 1:

[0032] like Figures 1 to 8As shown, a sealed bottle includes: a bottle body 1 and a bottle cap 2 connected to the bottle body 1. The bottle cap 2 is provided with a first through hole 21. An elastic sealing plug 3 is provided at the first through hole 21. The sealing plug 3 includes a sealing plug body 31 connected to the first through hole 21. A gap 400 is formed between the sealing plug body 31 and the hole wall of the first through hole 21. A sealing step 311 is provided on the top of the sealing plug body 31. The sealing step 311 is located on the outside of the bottle cap 2. When the inside of the bottle cap 2 is under negative pressure, the sealing step 311 can block the gap 400 to form a sealing structure.

[0033] In use, the item is placed into the bottle body 1, and then the bottle cap 2 is placed on the bottle body 1. The vacuum component is aligned with the first through hole 21 on the bottle cap 2 to create a vacuum in the bottle body 1. The air inside the bottle body 1 is gradually extracted through the gap 400 between the sealing plug body 31 and the wall of the first through hole 21. After the vacuum is completed, a negative pressure is formed inside the bottle body 1, causing the sealing plug body 31 to move downward. The sealing step 311 on the sealing plug body 31 forms a responsive sealing structure. When air is produced inside the bottle body 1... When negative pressure is generated, under atmospheric pressure, the sealing step 311 will move downward and automatically press and seal the gap 400 between it and the inner wall of the first through hole 21, sealing the bottle cap 2 and ensuring timely sealing. Moreover, when it is necessary to release the negative pressure, the sealing step 311 is pulled up, causing the sealing step 311 to move upward and separate from the gap 400, thereby allowing the gap 400 to conduct the bottle body 1 to the outside. At this time, the bottle body 1 can release the negative pressure. After the negative pressure is released, the bottle cap 2 can be easily unscrewed.

[0034] like Figures 2 to 3 As shown, the sealing plug body 31 is also provided with an indicator part 32 protruding to the top of the sealing plug body 31. When there is a negative pressure inside the bottle cap 2 and the bottle body 1, the indicator part 32 retracts into the sealing plug body 31. When there is a negative pressure inside the bottle cap 2 and the bottle body 1, the indicator part 32 retracts into the sealing plug body 31, allowing the user to easily observe the state inside the bottle cap 2 and the bottle body 1. Once the negative pressure inside the bottle cap 2 and the bottle body 1 decreases or disappears due to air leakage or other reasons, the indicator part 32 returns to the state of protruding outside the top of the sealing plug body 31, thereby realizing real-time monitoring of the vacuum state inside the bottle cap 2 and the bottle body 1, and promptly prompting the user to perform re-vacuuming or check the airtightness.

[0035] like Figures 2 to 3 As shown, a channel 312 is provided inside the sealing plug body 31, and the indicator part 32 is disposed on the wall of the channel 312, with a portion of the indicator part 32 extending from the channel 312 to the top opening of the sealing plug body 31. The channel 312 provides guidance and space for the extension or retraction of the indicator part 32, making the overall structure more compact.

[0036] like Figure 3 As shown, the indicator part 32 includes a connecting ring 321 that can be connected to the wall of the channel 312. The connecting ring 321 is provided with an arc-shaped connecting part 322, and an upwardly protruding indicator post 323 is provided in the middle of the connecting part 322. The arc-shaped connecting part 322 allows the indicator post 323 to protrude beyond the top opening of the sealing plug body 31. Moreover, when the bottle body 1 is under negative pressure, the connecting ring 321 and part of the connecting part 322 elastically deform, causing the indicator post 323 to retract into the channel 312.

[0037] like Figure 3 , Figure 5 and Figure 6 As shown, the sealing plug body 31 has a protruding ring 313 at the top opening of the channel 312, protruding into the channel 312. The protruding ring 313 has a second through hole 3131 for the indicator post 323 to extend out. The second through hole 3131 can position and guide the indicator post 323.

[0038] like Figure 3 , Figure 5 and Figure 6 As shown, the sealing plug body 31 includes a ring-shaped sealing ring 314 with a channel 312. The top of the sealing ring 314 has a sealing step 311, and the bottom of the sealing ring 314 has a stop 315 to prevent it from detaching from the first through hole 21. The stop 315 is located inside the bottle cap 2. The sealing step 311 on the outer side of the bottle cap 2 and the stop 315 on the inner side of the bottle cap 2 together form a bidirectional limiting structure, firmly locking the sealing ring 314 in the first through hole 21 of the bottle cap 2, preventing accidental detachment or displacement of the sealing ring 314, and ensuring stability during use. During installation, the stop 315 can elastically deform and pass through the first through hole 21, and then recover its deformation after passing through, achieving quick snap-fit ​​fixation, making assembly simpler and more efficient.

[0039] like Figure 3 , Figure 5 and Figure 6 As shown, the sealing step 311 and the stop portion 315 are spaced apart to form a movable space 600 that allows the sealing ring 314 to move up and down relative to the bottle cap 2. The movable space 600 allows the sealing ring 314 to float up and down relative to the bottle cap 2 to a limited extent, which can accommodate bottle caps 2 of different thicknesses and has a wider range of applications.

[0040] like Figure 5 and Figure 6 As shown, the sealing plug 3 and the indicator part 32 are integrally formed, which is convenient for processing.

[0041] like Figure 2 As shown, the bottle cap 2 is provided with a first sealing ring 7 that can seal the opening of the bottle body 1. The first sealing ring 7 acts as a sealing element, directly acting on the opening of the bottle body 1 to ensure the airtightness between the bottle cap 2 and the bottle body 1.

[0042] Example 2: As Figures 7 to 11 As shown, the difference between Embodiment 2 and Embodiment 1 is that the bottle cap 2 includes a cover plate 22 that can seal the opening of the bottle body 1, and an outer cap 23 that can be connected to the bottle body 1 and press the cover plate 22 tightly. The sealing plug 3 is connected to the cover plate 22. The bottle cap 2 adopts a split design, which makes it easy to unscrew the outer cap 23 from the bottle body 1. When it is necessary to remove the cover plate 22, pull up the sealing plug body 31 to allow air to enter the bottle body 1 through the gap 400, so that the pressure inside and outside the bottle body 1 is equal, and then the cover plate 22 can be easily removed. Moreover, in actual assembly, the sealing plug 3 and other components can be assembled onto the cover plate 22 first to form a complete component. During final assembly, simply place the component at the bottle mouth and then screw on the outer cap 23 to press it tight, which is very convenient to use.

[0043] like Figure 10 As shown, the cover plate 22 is provided with a second sealing ring 8, the outer cover 23 is provided with a third through hole 231, and the outer cover 23 is also provided with a downward protruding pressing ring 232 that presses against the cover plate 22. The second sealing ring 8 improves the airtightness between the cover plate 22 and the bottle body 1, and the third through hole 231 can position the air extraction device for easy air extraction. When the knob of the outer cover 23 is in the correct position, the pressing ring 232 can stably press against the cover plate 22, thus improving the airtightness between the cover plate 22 and the bottle body 1.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
