Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum-sealed lid module and a vacuum-

The present invention relates to a vacuum enclosed lid module. And more particularly to a vacuum hermetic lid module capable of preventing deformation of the packing member and enhancing a sealing force in a process of vacuuming the interior of the container body by using a vacuum pump after coupling the container lid on the container body, And to a vacuum sealed container having such a vacuum enclosure.

In general, a vacuum container accommodates predetermined foods and closes them, so that they can be safely stored in a vacuum for a longer period of time.

The air inside the container is discharged to the outside by using a vacuum device integrally connected to the body of the vacuum container or a vacuum pump separately provided from the container. Accordingly, the interior of the container is maintained in a vacuum state or a low pressure state, so that the food or the like contained in the container is prevented from being easily decayed by the oxidizing action of the air.

There is a vacuum evacuation apparatus of Korean Registration No. 10-1144500 (2012.05.02) in relation to a vacuum pump so as to discharge and seal the inside air.

Generally, a hermetically sealed container is an article used for storing food or the like in a vacuum state, and is provided with a container having a shape of square, circular, rectangular or the like and a lid which is openably and closably fastened to the container.

Conventional airtight container is a structure that simply encloses food in a storage container and closes only the lid to seal the food in the container. As a result, the food in the container is easily corroded by the propagation of bacteria and can not be stored for a long time. However, since the container is not completely vacuumed or the container is opened frequently, the entrance of the wavy air into the container causes the bacteria to easily breed There is a problem that the content of side dishes, condiments and the like is easily oxidized and corroded and is not stored for a long period of time.

Conventional containers for food preservation are all in a sealed state, but in reality, they can not pass water just like Gore-Tex, and the air is finely exchanged with the outside while being convectively operated. Therefore, The outside air can not penetrate into the container through the packing member. This is because, even if the packing member and the container are in close contact with each other, the ambient air and the inside of the container depend solely on the packing member, so that there is a limitation in preventing penetration of the outside air when the packing member is deteriorated or defective.

As a conventional literature related to a vacuum sealed container, reference can be made to registered patents 10-1246244, 10-1291091, and 10-1301367. The above documents disclose a technique in which a sealing member or a packing member is applied in order to enhance the hermeticity when a lid is coupled onto a container.

Particularly, it can be seen that the packing disclosed in the 10-1246244 is formed in a multi-stage state in which a plurality of blades are spaced apart from each other. Under this structure, when the vacuum pressure is formed, There is a problem in that the shape of the packing is eventually destroyed, the defect is succeeded, the deformation between the wings is easily generated and the vacuum is difficult to maintain, and the cost for the packing is considerably increased due to the complexity of the mold.

The vacuum hermetic lid module according to the present invention improves the shape of a packing member coupled to a lid of a container, thereby joining the container lid on the container body and vacuuming the inside of the container body by using a vacuum pump, The sealing force can be enhanced while preventing deformation.

The present invention reinforces the shape of the packing member in such a way that it abuts against strong pressure to prevent it from being easily turned over. On the other hand, the conventional art has a problem in that a round process is performed so that the ship is inverted and the packing is inverted easily when the vacuum pressure is applied.

The present invention stably positions a vacuum-sealed lid module such as a frying pan, a pot casserole, etc. with a handle.

That is, in the conventional art, when the vacuum pressure is increased, the problem that the lower part of the supporting ring of the packing member and the mounting wall of the vacuum lid are widened and overturned overturns over time is solved.

The conventional technique overcomes the problem that the lid is not positioned at the center of the container while two or more wings constituting the packing member are overlapped and the unevenness of the engagement portion is generated and the vacuum duration time is shortened in the end.

In addition,

In addition, the present invention stably accommodates the packing member on the packing seat formed through the support and protection guides constituting the container lid, thereby maintaining the overall sealing performance of the vacuum sealed container even when repeated opening and closing operations are performed .

Further, the present invention improves the vacuum sealing force and reduces the manufacturing cost through the process of manufacturing the packing member in a simple shape.
