Description

  The present invention belongs to a food container.

  Individuals and homes often purchase large bottles of carbonated drinks in multiple doses until they are consumed. Therefore, the bottle lid is frequently opened, which causes gas deaeration in the beverage. Often, all of the gas has already been degassed even though there is still a lot of beverage left in the bottle, greatly affecting the quality of the carbonated beverage. The invention according to Patent Document 1 solves this problem, but the structure is very complicated, the production cost is high, and it is difficult to spread in the market.

US Pat. No. 5,909,824

  Because the market for large bottles of carbonated beverages is huge, it is necessary to provide the market with inexpensive and high quality parts to prevent large bottles of carbonated beverages from being degassed in multiple drinking. The two-way valve provided with a safety mechanism for separating the carbonated beverage of the present invention from a large bottle into a container is such a part.

  The idea of the present invention is to connect a large bottle of carbonated beverage bottle and a small container with a two-way valve, open the two-way valve, pour carbonated beverage into the container, then close the two-way valve, and turn the two-way valve into a large bottle of carbonated beverage By leaving the bottle and removing the container in which the beverage is separated, the gas of the carbonated beverage in the large bottle is maintained until the end. Test results with the inventive sample proved that this idea was feasible.

  During the test, it was found that the bottle seal ring could be blown out at high speed by pressure gas. It is important to add a safety mechanism to the two-way valve to prevent the bottle seal ring from being blown out by pressure gas because the bottle seal ring is very dangerous if it accidentally hits the eyes of a drinker.

A two-way valve with a safety mechanism for separating carbonated beverages from large bottles into containers,
A valve body, a valve core, a handle, and a bottle seal ring,
The valve body has an inlet having a female thread that matches the male thread of the large bottle, and an outlet having a female thread that matches the male thread of the container,
The bottom of the female screw at the outlet of the valve body and the bottom of the female screw at the inlet each have a safety mechanism that prevents the bottle seal ring from being blown out by pressure gas.

  The safety mechanism is an axial ring-shaped groove that is recessed in the axial direction at the bottom of the female thread at the inlet of the valve body and the bottom of the female thread at the outlet, and one surface of the axial ring-shaped groove is formed by the axial ring-shaped groove. It is a female thread extending to the bottom, the other surface of the axial ring-shaped groove is a groove wall, the depth of the axial ring-shaped groove is larger than the thickness of the bottle seal ring, and the width of the axial ring-shaped groove is It is larger than the width of the male screw of the large bottle.

  The safety mechanism is a radial ring-shaped groove that is recessed in the radial direction at the root of the female screw at the inlet of the valve body and the female screw at the outlet.

  The axis of the outlet of the valve body and the axis of the inlet are perpendicular or obtuse.

  The two-way valve provided with the safety mechanism is a ball valve.

It is a schematic diagram of the two-way valve provided with the safety mechanism for dividing the carbonated beverage of this invention into a container from a large bottle. The inlet connects to a large bottle of carbonated beverage and the outlet connects to a carbonated beverage container. It is a schematic diagram which shows the safety mechanism for preventing that a bottle seal ring is blown off by pressure gas. It is a schematic diagram which shows the other safety mechanism which prevents that a bottle seal ring is blown off by pressure gas.

  As shown in FIG. 1, the safety two-way valve 3 for dividing the carbonated beverage of the large bottle 1 into the container 2 includes a valve body 4, a valve core 5, a handle 6, and bottle seal rings 7 and 8. .

  The valve body 4 has an inlet 9, an outlet 10, a valve chamber 11, and a passage that connects the inlet 9, the outlet 10, and the valve chamber 11 to each other. The valve core 12 of the valve core 5 is in the valve chamber 11 and is rotatable in the valve chamber 11. The valve core 5 has a valve core hole 13 and a valve core rod 14. The valve stem 14 extends to the outside of the valve body 4 and a handle 6 is attached. A seal ring 15 is provided between the valve stem 14 and the valve body 4. The inlet 9 and the outlet 10 have an internal thread 16 and an internal thread 17, respectively. The inlet female thread 16 matches the large beverage bottle male thread 18 and the outlet female thread 17 matches the small bottle male thread 19.

  A safety mechanism 20 for preventing the bottle seal ring from being blown out by pressure gas is provided at the bottom of the female screw at the outlet and the bottom of the female screw at the inlet. The outlet safety mechanism and the inlet safety mechanism have the same structure.

  The axis of the inlet 9 of the valve body and the axis of the outlet 10 are orthogonal to each other or form an obtuse angle.

  As shown in FIG. 2, the safety mechanism 20 is an axial ring-shaped groove 21 that is recessed in the axial direction into the bottom surfaces of the internal threads 16 and 17 of the inlet and outlet of the valve body. One surface of the axial ring-shaped groove 21 is an internal thread 16, 17 extending to the bottom 23 of the axial ring-shaped groove 21, and the other surface of the axial ring-shaped groove 21 is a groove wall 22. The depth H of the axial ring-shaped groove 21 is greater than the thickness Hm of the bottle seal rings 7, 8 and the width G of the axial ring-shaped groove 21 is greater than the width T of the male thread of the bottle.

  The axial ring-shaped groove 21 has bottle seal rings 7, 8 which are made of elastic plastic. The width Gm of the bottle seal rings 7 and 8 and the width G of the axial ring-shaped groove 21 fit tightly. The outer diameter Pm of the seal rings 7 and 8 is equal to the inner diameter P of the female threads 16 and 17, and the inner diameter Dm of the seal rings 7 and 8 is larger than the outer diameter D of the groove wall 22 of the axial ring-shaped groove 21.

  The cross section of the axial ring-shaped groove 21 is rectangular, and the cross sections of the bottle seal rings 7 and 8 are also rectangular. Alternatively, the cross section of the axial ring-shaped groove 21 may be rectangular, and the cross sections of the bottle seal rings 7 and 8 may be circular.

  Since the depth H of the axial ring-shaped groove 21 is greater than the thickness Hm of the bottle seal rings 7, 8, the pressure of the released gas cannot blow off the bottle seal rings 7, 8, and therefore the bottle seal ring 7 and 8 are guaranteed not to be blown out.

  As shown in FIG. 3, the guarantee mechanism 25 has a different structure. The guarantee mechanism 25 is a radial ring-shaped groove 26 that is recessed in the radial direction at the root portion between the female screw at the outlet of the valve body and the female screw at the inlet. The bottle seal ring 28 is made of an elastic plastic, and its thickness is smaller than the width of the radial ring-shaped groove 26, its outer diameter is larger than the inner diameter of the female screw, and its inner diameter is smaller than the inner diameter of the bottle. Since the bottle seal ring is fitted in the radial ring-shaped groove 26, the pressure gas does not blow off the bottle seal ring 28.

  The valve outlet and inlet female threads 16, 17 are manufactured in accordance with beverage bottle specifications of the International Society Beverage Technologists. For carbonated beverage bottles of 2 liters or less, the male thread standard is the PCO standard 28 mm neck finish, and the male thread dimensions are the same.

  The method of use of the present invention is to open a large bottle of carbonated beverage, tighten the inlet of the safety two-way valve to the bottle mouth of the carbonated beverage bottle, tighten the outlet of the safety two-way valve to the container, and open the safety two-way valve. The carbonated beverage is poured from the large bottle into the container, then the safety two-way valve is closed, the safety two-way valve is left on the carbonated beverage large bottle, the container containing the beverage is removed, and the operation of dividing the container into the container is completed. The closed safety two-way valve seals the large bottle of carbonated beverage, so that the beverage gas in the large bottle is maintained until it is consumed, and has a high pressure.

  This application claims priority from US Provisional Application No. 6,188,341, filed Oct. 5, 2013, which is hereby incorporated by reference.
