Definitions
- the present invention relates to a vacuum food container, more particularly to a vacuum food container which discharges gas formed during ripening or cooking process of the food stored in a vacuum state in the vacuum food container, while preventing discharging of the food contents .
- a vacuum food container has been used widely for long-time safe-keeping and quality maintainance of food. Described below is a conventional food container for storing foods such as fermented food or instant food.
- FIG. 1 is a cross-sectional view of a conventional vacuum food container.
- food 13 can be stored inside of a food container 10.
- a mouth at the upper portion of a food container 10, and a ring-shape protrusion 11 is formed around the mouth.
- a lid 20 of the food container 10 maintains the sealing state and is affixed to the food container 10 using ring-shape protrusion 11.
- FIG. 2 is an enlarged cross-sectional view of a conventional vacuum food container showing a combination state of ring-shape protrusion 11 and lid 20 as shown in FIG. 1.
- a ring-shape protrusion 11 having projection and depression portions around the mouth of the food container 10.
- a hooked jaw 21 which can be hooked at ring-shape protrusion 11 around circumference of the lid 20.
- a gasket 25 made of a material such as thermoplastic material or rubber.
- lid 20 The assembly process of lid 20 is operated by the vertical force to the upper surface of the lid 20. Then a part of compressed hooked jaw 21 is recovered, and ring- shape protrusion 11 is adhered closely to the hooked jaw 21. At that time, gasket 25 is adhered closely to the upper portion of ring-shape protrusion 11, and inside of the food container 10 is sealed up. Thereafter, the vacuum state of the food container 10 is maintained.
- the inner pressure is maintained at a lower state than the outer pressure because the inside of the container is a vacuum. Since lid 20 is adhered closely to the food container 10, it prohibits overflowing of the contents.
- a vacuum food container having gas discharging means so that the container discharges gas formed during ripening or cooking process only and prevents discharging the contents .
- the above object of the present invention can be achieved by providing a vacuum food container comprising a container having a ring-shape protrusion formed around a mouth; a lid having a hooked jaw to cover the food container; an elastic body having a ring shape inside the lid to adhere closely to the upper portion of the ring-shape protrusion; and discharging means formed in the lid for discharging gas generated from the food.
- the cross-section of the elastic body comprises a gasket having a downward slope in a radial direction.
- the discharging means includes a gas circulation groove formed around the elastic body and at least one incision groove formed by incising the section of the hooked jaw. At thi ⁇ time, it is possible that the incision groove is formed plurally at equal distance ⁇ along the hooked jaw.
- the vacuum food container maintains the vacuum state because the gasket is adhered closely to the upper portion of the ring- shape protrusion. If gas is generated, inner pressure rises, which makes a gap between the gasket and the ring- shape protrusion. The gas which is discharged at the gap is discharged outside through gas circulation groove and incision groove which exists at hooked jaw.
- FIG. 1 is a cross-sectional view of a conventional vacuum food container
- FIG. 2 is a cross-sectional enlargement view of a conventional vacuum food container as shown in FIG. 1 showing a combination state of ring-shape protrusion and lid;
- FIG. 3 is a cross-sectional view of a vacuum food container according to one embodiment of the present invention
- FIG. 4 is an enlarged cross-sectional view of a vacuum food container showing a combination state of ring- shape protrusion and lid and a flow of gas shown in FIG. 3;
- FIG. 5 is a partial cross-sectional view of a vacuum food container showing a lid shown in FIG. 3;
- FIG. 6 is an enlarged cros ⁇ - ⁇ ectional view of a vacuum food container ⁇ howing a gasket area ⁇ hown in FIG. 5;
- FIG. 7 is a bottom view of a vacuum food container showing a lid shown in FIG. 3;
- FIG. 8 is an enlarged cross-sectional view of a vacuum food container showing incision groove area shown in FIG. 7.
- FIG. 3 is a cross-sectional view of a vacuum food container according to one embodiment of the present invention. According to FIG. 3, food 41 is contained inside of the food container 40 and the mouth located at the upper portion of the food container 40 is assembled with lid 30.
- FIG. 4 is an enlarged cros ⁇ -sectional view of a vacuum food container showing a combination ⁇ tate of ring- shape protrusion 43 and lid 30 and a flow of gas shown in FIG. 3.
- the solid line represents the position of lid 30 in a tightly sealed state
- the dotted line represents the position of lid 30 in a gas discharging ⁇ tate in FIG. 4.
- This ring-shape protrusion 43 can be adhered closely to the hooked jaw 31 which i ⁇ protruded in ⁇ ide from ⁇ ide wall 37 of lid 30.
- Hooked jaw 31 is formed uniformly around the circumference direction of the side wall 37.
- the incision groove 35 which is incised along the cross-section of hooked jaw 31 is formed at the same distance.
- a ring-type gasket 39 is put between upper portion of ring-shape protrusion 43 and inside of lid 30.
- the gasket 39 is assembled to lid 30.
- a cross-section of gasket 39 shows a trapezoid type having a downward slope in a radial direction.
- Gasket 39 is made of a material such as thermoplastic material, rubber, etc.
- the gas circulation groove 38 is formed sinkingly between gasket 39 and hooked jaw 31.
- the gas circulation groove 38 is a ring shape around the circumference of lid 30, and sinks towards the upper portion of lid 30.
- Fig. 5 is a partial cros ⁇ - ⁇ ectional view of a vacuum food container showing a lid shown in FIG. 3. According to FIG. 5, the height of lid 30 is relatively lower than the height of food container 40, and incision groove 35 is located at hooked jaw 31 at same distance.
- the constitution of lid 30 is the same as indicated in the explanation of FIG. 4.
- FIG. 7 is a bottom view of a vacuum food container showing a lid 30 shown in FIG. 3. According to FIG. 7, the lid 30 is formed in a circular shape. The gasket 39 is formed uniformly at the edge area of lid 30.
- FIG. 8 is an enlarged cross-sectional view of a vacuum food container showing incision groove area shown in FIG. 7.
- the side wall 37 is formed at the edge of lid 30, and the hooked jaw 31 protrudes from side wall 37 towards the inside of lid 30 at the inside of side wall 37.
- the incision grooves 35 are arranged at 60 degrees from center of lid 30.
- the gasket 31 is fixed at the hooked jaw 31.
- the food 41 is stored in the food container 40, after which the inside of the food container 40 i ⁇ made into a vacuum state.
- the lid 30 As shown in FIG. 4, as the inner pressure of food container 40 becomes higher, the lid 30 is lifted. The position of lid 30 is indicated with a dotted line. The inner pressure pushes up the lid 30, thus the portion of gasket 39 is recovered by elasticity. Then, the gas leak ⁇ through gap between ga ⁇ ket 39 and ring-shape protrusion 43. The leaked gas is discharged outside through gas circulation groove 38 and incision groove 35. If the gas circulation groove 38 does not exist for the microwave oven cooking, the lid 30 is sprung up and the food container 40 is opened or is exploded by gas expansion. Therefore, the gas circulation groove 38 absorb ⁇ the shock of gas expansion. When the pre ⁇ sure is lowered as the gas i ⁇ leaked, the gasket 39 adheres closely to upper portion of ring- shape protrusion 43 again by elasticity of hooked jaw 31.
- Fermented foods such as soybean pastes, thick soypastes mixed with red peppers, or pickled sea foods or instant foods can be packed within a vacuum state and circulated in a vacuum food container according to the present invention.
- the lid can be made of heat-resisting pla ⁇ tic, while the container can be made of glass. Therefore, the vacuum food container is helpful to recycle resources and to protect environment. Moreover, the packing cost can be reduced since the structure is simple.
- the vacuum food container according to the present invention can maintain the sealed ⁇ tate and di ⁇ charge the ga ⁇ with appropriate pre ⁇ ure, even though the gas was generated inside according to the ripening or cooking of food. Therefore, discharging of the contents due to high pres ⁇ ure will be prevented. Accordingly, benefit ⁇ include the smooth ripening of food, convenience and high quality of goods .
