The invention relates to a vacuum-sealed container, and more particularly to a vacuum-sealed container which can contain food in the sealed state with simple and convenient structure.
BACKGROUND ARTGenerally, foods such as vegetables, meats and fishes are oxidized and spoiled by contacting microorganism, oxygen or other harmful materials. Specifically, breeding speed of microorganism in fermented foods is so high that the foods could excessively ferment and, as a result, taste of the foods cannot be properly maintained. In order to prevent the foods from deteriorating or decaying and delay fermentation of foods, the foods should be kept from contacting outer airs. For this purpose, sealing containers are suggested in which container cover has packing ring on the periphery of it to be engaged with container body airtightly. Even though the conventional sealing container can prevent outer air from flowing into the container, it cannot prevent the foods from decaying or excessively fermenting due to inner air. To solve this problem, other type of sealing container is suggested which includes a valve on the container cover and it can be vacuumed by a separated pumping device, but it is cumbersome as the separated pumping device is required in addition to the container body and the container cover, and it can be lost if it is not carefully kept. And, to make the container vacuum, the pump device should be placed to be aligned with the valve of the container cover and handle it in this state, which may not be easily performed.

The container body 10 is formed as a case with an opening on the upper part of it and has locking projections 11 to detachably clamp the container cover 20. The container cover 20 can be engaged on the upper of the container body 10 and has a recess 21 on the upper surface of it to accommodate the handle 30 and an intake hole 24 in which the intake valve 60 is plugged. As shown in
The handle 30 includes a pair of rotating cylinders 31 having first ends rotatably coupled to the respective hinge portions 22 of the container 10, a pair of elevating bars 36 rotatably coupled to the rotating cylinders 31, and a connecting bar 37 connecting the elevating bars 36 to be gripped by user. The pair of elevating bars 36 and the connecting bar 37 may form of U shape. The rotating cylinder 31 comprises a horizontal portion 31a engaged with each hinge portion 22 of the container cover 20 at the first end and a vertical portion 31b extending upward from the second end of the horizontal portion 31a and engaged with the elevating bar 36 to form of L shape. As shown in
Meanwhile, as shown in
The first check valve 40 opens/closes the inlet 32 of the rotating cylinder 31 to exhaust air in the container body 36 through the channels 34,34 of the handle 30, but it prevents the air in the channels 34,35 from flowing into the container body 10. The first check valve 40 is provided on the hole 23 of the hinge portion 22 of the container cover 20, or on the inlet 32 of the rotating cylinder 31 of the handle 30.
The second check valve 50 opens/closes the channel 38 according to the up-down movement of the elevating bar 36 and it is made of ring-shaped rubber member and it is inserted between the upper disc 36a and the lower disc 36b. The second check valve 50 is attached on the inner wall of the rotating cylinder 31 to partition the channel of the rotating cylinder 31 into an upper channel 34 and a lower channel 35. As shown in
The intake valve 60 is plugged on the intake hole 24 of the container cover 20 and it can release a vacuum state inside the container boy 10 sealed by the container cover 20 to make it easy to open the container cover 20 from the container body 10. The intake valve 60 is preferably opened by pulling or pushing operation.
Hereinafter, the method to form vacuum state in the container is explained. As shown in
As shown in
As the above mentioned operation is repeated, the air inside the container body 10 exhausts to the outside of the container, and the inner space of the container 10 becomes vacuum, so that the decaying or fermenting of the foods inside the container 10 will be retarded, and the foods can be kept fresh for long time.
Meanwhile, a first check valve 40 is attached on the inlet 32 of the rotating cylinder 31 of the handle 30.
