Description

  The present invention relates to a cap device, and more particularly to a cap device that forms a vacuum inside a bottle.

  Currently, bottles used to fill liquids (for example, alcoholic beverages, juices, carbonated water, oil) in daily life are usually sealed with a cork stopper, metal cap, plastic cap or the like before opening. However, after opening, the liquid inside the bottle comes into contact with the gas and is therefore susceptible to degeneration or growth of bacteria. For this reason, how to maintain the sealing of the bottle so as not to change the quality of the liquid contained in the bottle is a problem that should always be solved.

  Chinese utility model CN202414395U discloses an integrated vacuum cap including a plug body, an intake handle that reciprocates in response to the plug body, and a spring. When the intake handle receives pressure and moves toward the plug body, the air in the cavity disposed in the intake handle and the plug body is discharged. When the intake handle is not under pressure, the spring provides resilience and springs back with the intake handle up. The space of the cavity arranged in the intake handle and the stopper body is increased, and the unidirectional valve located below the vacuum cap is opened to suck the gas in the bottle into the cavity. Then, after pushing several times, the gas in the bottle is constantly extracted and approaches a vacuum.

  However, the cap device described above is too bulky and does not meet the consumer's appearance preferences of the consumer in today's society. On the other hand, when the air is sucked into the vacuum, it is operated manually, which greatly reduces the convenience and practicality of use. Further, when it is desired to remove the liquid in the bottle, the cap device needs to be completely removed from the opening of the bottle, so that a large amount of air enters the inside of the bottle, thereby accelerating the deterioration of the liquid.

The difference between the cap device 1 ′ and the cap device 1 is that the cap device 1 ′ further includes a vacuum holding component 20 installed on the upper lid 10. Specifically, the vacuum holding component 20 includes a rod 22 and two or more hermetic rings (eg: first hermetic ring 24 and second hermetic ring 26). The rod 22 is installed in the perforation 1033 of the bottom 1031 of the concave groove 103 and is installed in the passage 104 of the upper lid 10 in a movable manner. The first hermetic ring 24 and the second hermetic ring 26 are installed between the outer surface of the rod 22, the inner wall surface of the passage 104, and the inner wall surface of the passage 104. The first hermetic ring 24 and the second hermetic ring 26 are spaced from each other. In some embodiments, the spacing between the first hermetic ring 24 and the second hermetic ring 26 is greater than the width of the side tube portion 146 of the vacuum generator 14.

  When a vacuum is formed on the bottle 2 (FIG. 1) using the cap device 1 ', the vacuum holding component 20 is disposed at the first position (FIG. 4). At this time, the first and second hermetic rings 24 and 26 are separated from the tubular member 18 as compared with the side tube portion 146. The gas is sucked out of the passage 104 by the side tube portion 146. After the vacuum in the bottle 2 is established, the vacuum holding component 20 moves to the second position (FIG. 5). At this time, the rod 22 contacts the tubular member 18 and the side tube portion 146 is disposed between the first and second hermetic rings 24 and 26, and the side tube portion 146 includes the first and second airtight rings. The airtight rings 24 and 26 are received and sealed. Since the passage 104 receives and seals the first and second hermetic rings 24, 26, no external gas can enter the bottle 2 by the passage 104 or the tubular member 18, so that the bottle 2 is in a vacuum state. The time to maintain is extended.

  FIG. 6 shows a cross-sectional view of a cap device 1 'according to some embodiments of the present invention. The difference between the cap device 1 ″ and the cap device 1 is that the sealing material 19 of the cap device 1 is replaced by a sealing material 30 and the cap device 1 ″ further includes an air valve 5. The sealing material 30 has a ring-like structure and is disposed on the outer surface adjacent to the end of the tubular member 18. The air valve 5 is disposed at the opening of the bottle 2 and selectively allows fluid to communicate with the inside and outside of the bottle 2.

Next, in the same manner as the operation method of the cap device 1, the air in the bottle 2 is sucked by the air valve 5 to establish a vacuum inside the bottle 2. Next, the tubular member 18 is separated from the exhaust port of the air valve 5, and the air valve 5 is installed alone on the opening of the bottle 2. At this time, the air valve 5 is disposed in a closed state, and the bottle 2 receives and seals the air valve. When it is desired to take out the liquid in the bottle 2, the liquid in the bottle 2 can be taken out by opening the air valve 5 first and removing the air valve 5 from the opening of the bottle 2. Compared to the cap device 1, the cap device 1 ″ can achieve the purpose of sealing the bottle 2 only by holding the air valve 5 on the bottle 2. Therefore, the cap device 1 ″ is more preferable. Has convenience of use.

  The cap device of the present invention achieves the purpose of sealing the bottle 2 by fluid drive, and is more convenient and easier to use than a conventional cap device driven by a manual method. Moreover, the cap apparatus of this invention can maintain the vacuum degree of a bottle effectively, and can reduce possibility that the liquid inside a bottle will change in quality.
