  • FIG. 4 is a bottom view illustrating a first valve of a vacuum valve type airtight container according to the present invention.
  • FIG. 5 is a view illustrating a structure of a second valve of a vacuum valve according to the present invention.
  • the airtight container 1 comprises a container body 2 made by injecting a plastic material, a container lid 3 and a vacuum valve 4 which is made of a silicon rubber material.
  • the container lid 3 is air-tightly engaged at the container body 2 with the packing 5 being disposed between them.
  • the vacuum valve 4 comprises a first valve 6 and a second valve 7 .
  • the first valve 6 comprises a cylindrical part 8 , and a valve circular plate 9 integrally provided at an upper side of the cylindrical part 8 and being formed in a large circular plate shape.
  • a flange plate 10 is provided at a lower side of the cylindrical part 8 for preventing an escape of the same.
  • the cylindrical part 8 of the first valve 6 is inserted into a first valve engaging hole 11 formed at the container lid 3 and is movable in up and down directions. While contracting or expanding, the silicon rubber flange plate 10 flexibly passes through a first valve engaging hole 11 having a diameter smaller than the silicon rubber flange plate 10 , so that it is not escaped from the first valve engaging hole 1 unless a certain external force is applied thereto.
  • a first air flow slit groove 12 with a narrow width is formed on the cylindrical part 8 and the flange plate 10 in an up and down direction.
  • the valve circular plate 9 closely contacts with a surface of the container lid 3 , all air communication is disconnected between the inner and outer sides of the container.
  • the valve circular plate 9 moves up and is spaced apart from the surface of the container lid 3 , the first air flow slit groove 12 is exposed to the outside, and the inner and outer sides of the container communicate with each other along the groove 12 , so that air communicates.
  • a handle 13 is protruded from one side of the valve circular plate 9 for the use when the vacuum state is removed.
  • the handle 13 has an inclination gradually rising up in an outward direction and spacially gets loose all the time from the surface of the container lid 3 .
  • a second valve engaging hole 14 is formed at a center of the first valve 6 and passes through the same in an up and down direction.
  • a diameter contraction part 16 (an intermediate portion of the hole is narrower than the upper and lower sides of the same) having a step surface 15 is formed at an intermediate portion of the second valve engaging hole 14 and operates as a valve seat.
  • the second valve 7 is inserted via the second valve engaging hole 14 .
  • the second valve 7 is made of a silicon rubber having a good elastic and adhering property and comprises a valve shaft rod 17 passing through the diameter contraction part 16 , a valve head 18 which is formed at an upper side of the valve shaft rod 17 and contacts with the step surface 15 which forms the valve seat, and an escape prevention head 19 which is formed at a lower side of the valve shaft rod 17 .
  • the escape prevention head 19 passes through the inner diameter of the diameter contraction part 16 and is exposed through the expanded hole, the lower step surface 20 catches the same. In this case, it is impossible to allow the escape prevention head to escape from the hole without a certain external force.
  • the valve shaft rod 17 is longer than the up and down height of the diameter contraction part 16 protruded into an inner side of the hole, so that the second valve 7 can move up and down.
  • At least one second air flow slit groove 21 having a narrow width is formed at the diameter contraction part 16 in an up and down direction.
  • the second air flow slit groove 21 is not covered even when the escape prevention head 19 of the lower side is closely contacted with the lower step surface 20 , so that it is exposed via its up and down sides all the time.
  • the packing 5 is closely contacted with the inner wall surface 22 for thereby sealing the gap of the contact surfaces.
  • the first valve 6 of the vacuum valve 4 is pressed, and the valve circular plate 9 is closely contacted with the surface of the container lid 3 , and the connection part 24 of the vacuum pump 23 is connected with the upper hole 14 a of the second valve engaging hole 14 .
  • the second valve 7 moves up by means of a suction force, and the valve head 18 is spaced apart from the step surface 15 which corresponds to the valve seat.
  • the air of the interior of the container is sucked via the second air flow slit groove 21 , the upper hole 14 a , the connection part 24 and the vacuum pump 23 , so that the air is removed from the interior of the container, and the interior of the same becomes vacuum.
  • connection part 24 when the connection part 24 is separated, the second valve 7 is sucked by means of a vacuum pressure of the interior of the container and is closely contacted with the valve seat 15 , so that an air communication is disconnected. So, the air is substantially removed from the interior of the container, so that the food can be stored for a long time period.
  • the first valve 6 When the container lid 3 is opened, the first valve 6 is lifted in an upward direction while holding the handle 13 of the first valve 6 .
  • the first valve 6 is moved up.
  • the valve circular plate 9 When the valve circular plate 9 is spaced apart from the surface of the container lid 3 , it contacts with the first valve engaging hole 11 of the container lid 3 at the upper side of the first air flow slit groove 12 or is exposed toward an upper side. So, the inner and outer sides of the container communicate with each other via the first air flow slit groove 12 .
  • the air is inputted into the interior of the container via the first air flow slit groove 12 communicating with the outside having a relatively higher atmospheric pressure as compared to the interior of the container, so that the vacuum state is removed. As the suction force of the container lid 3 is removed, the container lid 3 can be easily uncovered from the container body 2 .
  • the second valve is provided at the center of the first valve so that the air is removed from the interior of the container for generating a vacuum state in the interior of the container with the assistance of the vacuum pump.
  • a vacuum valve is provided in a double structure. So, it is possible to make the vacuum pump compact-sized. The suction force of the air is enhanced, and the life span of the connection part can be extended.
