Description

[Detailed explanation of the idea] The present invention relates to an in-bottle gas release mechanism.

Gas is naturally generated from the contents inside the bottle, and this generated gas becomes under abnormally high pressure, which tends to cause accidents such as the bottle itself bursting or the stopper popping out.

In view of this, the present invention aims to prevent the bottle from bursting, the stopper from popping out, etc. by automatically releasing the gas generated inside the bottle to the outside of the bottle.

Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments.

Figure 1 is a central vertical sectional view, Figure 2 is A-A in Figure 1.
The A-line sectional view and FIG. 3 are explanatory views of the operation in a state where the bottle is overturned.

In the figure, 1 is a bottle spout, and 2 is an inner stopper that fits into the bottle spout 1. Further, the inner plug 2 has a gas venting hole 3 of a required diameter in the center of the top wall 2', and the periphery of the hole 3 is bulged upward.

Reference numeral 5 denotes a valve part whose lower surface comes into close contact with the upper surface of the bulging part 4 when the cap is screwed onto the bottle opening 1, and whose upper end is in a recessed part 15 bored into the inner surface of the top wall of the cap, which will be described later. It is embedded. Further, the valve part 5 has a recessed part 6 of a required diameter and depth in the center of its upper surface, and the gas in the recessed part 6 is directed to the inner surface of the vertical wall of the cap described later and to the valve part. A through hole 7 for discharging water into the gap between the gas and the gas 5 is bored. Furthermore, the valve portion 5
An inverted conical (mortar-shaped) valve chamber 8 whose diameter becomes smaller toward the bottom is provided in the center of the valve chamber 8, and the lower opening of the valve chamber 8 communicates with the through hole 3, and the upper opening thereof It is closed by a thin plate 10 having a gas venting hole 9 in the center. Furthermore, a required number of vertical protrusions 11 are provided on the inclined surface of the valve chamber 8, and a stepped portion 11' having a predetermined height is formed at the upper end of the protrusions 11. The height of the stepped portion 11' is set to be slightly larger than the thickness of the valve plate described later.

12 is a valve plate placed on the stepped portion 11' of the protrusion 11; when the bottle is standing, there is a slight gap between the top surface of the bottle and the bottom surface of the thin plate 10; Being able to move.

Reference numeral 13 denotes a sphere housed in the valve chamber 8 so as to be freely movable. Reference numeral 14 denotes a cap that is screwed onto the bottle mouth 1, and a recess 15 into which the upper end of the valve portion 5 is inserted is bored in the inner surface of the top wall 14'.

Next, the mode of operation of the present invention will be explained.

When the contents are put into the bottle through the mouth 1, the inner stopper 2 is inserted, and the cap 14 is screwed on, the state shown in FIG. 1 is obtained. When gas is generated in this state, the generated gas rises and flows into the valve chamber 8 of the valve portion 5 through the through hole 3 of the inner stopper 2. In this case, since the sphere 13 is suspended from the inclined surface of the valve chamber 8 by the ridges 11, the gas flowing from the through hole 3 passes between the ridges 11 and 11. It flows upward into the valve chamber 8. The gas that has reached the upper part of the valve chamber 8 passes through the valve plate 1
2 and the thin plate 10, and further flows into the concave portion 6 through the through hole 9. Further, it flows from the through hole 7 into the gap between the vertical wall inner surface of the cap 14 and the valve part 5,
Finally, it is released into the atmosphere.

Furthermore, when the bottle falls, the valve plate 12 is pressed by the rolling of the sphere 13, as shown in FIG.
comes into close contact with the thin plate 10 and closes the through hole 9 provided therein. Therefore, the outflow of stored materials is prevented.

Furthermore, the same effect occurs when the bottle is shaken while standing.

To explain this point concretely, if the bottle shakes greatly while standing, the mouth of the bottle will shake greatly from side to side.
At this time, the sphere 13 slides up and down the inclined surface of the valve chamber 8 along the protrusion 11. When this sphere 13 moves up the slope, it presses the valve plate 12 and closes the through hole 9. Although this closure is instantaneous, it has the effect of reliably reducing the leakage of contents inside the bottle.

Since the present invention has the above-described structure and function, it is possible to automatically release the gas naturally generated inside the bottle to the outside of the bottle, thereby preventing the bottle from bursting or the stopper from popping out due to gas pressure. be able to. Furthermore, even if the bottle falls over, there is no risk of the contained contents leaking outside. In addition, it has the effect of reliably reducing the leakage of the contents when the bottle shakes greatly while standing, and is thus highly effective in practical use.
