Description

Vacuum generating device for vacuum packing bag

The present invention relates to a vacuum generating device for a vacuum packaging bag for use in a vacuum packaging bag that can be conveniently stored in a variety of foods and foods can be stored in a vacuum state that can maintain freshness.

In general, a vacuum packaging bag (also called a "zippered bag") is used as a means for storing various foods or foods in a vacuum.

Briefly describing the structure of the vacuum packaging bag, the opening and closing to open the opening of the storage space is composed of a packaging bag main body having a storage space with one side, and a female / male zipper openly It is composed of a zipper, the apparatus for forming the storage space of the packaging bag body in a vacuum atmosphere is a packaging bag vacuum device.

In particular, the vacuum device is mainly for pumping (pumping) to form the inside of the bag body in a vacuum atmosphere, provided with a passage opened and closed by a check valve (check valve) is provided on one side of the bag body And a pumping port which is detachably connected to one end of the connecting port and generates a suction force by pumping (forward / backward) of the piston to vacuum the storage space through the passage.

In addition, the check valve has a structure of opening or blocking the passage by an operation of moving to one side or the other side in the connection port by a pin type.

That is, the check valve, for example, when a suction force is generated by the pimping of the pumping port, the passage moves to one side by a suction force acting inside the connection port (backward), and when the suction force is released, the check valve acts on the storage space. The opening and closing operation is performed in a manner of moving (advancing) to the other side by the vacuum pressure to block the passage again.

It is very important to operate the pumping port and the connecting port so that the vacuum pressure is not released when the inside of the vacuum packaging bag is formed in the vacuum atmosphere using the vacuum device.

However, in the vacuum apparatus having the above-described structure, the following problems may occur when the storage space of the bag main body is formed in a vacuum atmosphere by using the pumping port and the connection port.

For example, a slight time difference occurs when the check valve of the connection port automatically shuts off the passage by the vacuum pressure acting on the storage space while the passage is open, so that the vacuum pressure of the storage space passes through the passage. Can be easily released (lossed).

In particular, since this phenomenon occurs mostly in the step of separating the pumping port from the connection port in a state where the storage space is formed in a vacuum atmosphere, a vacuum degree capable of preventing the deterioration of various foods or foods in response to the storage space is formed. Difficult to do

Such problems are because, for example, it is not provided with means for forcibly shutting off the check valve when disconnecting the pumping port from the connecting port or in conjunction with a pumping operation (forward / backward of the piston). .

In addition, since the vacuum apparatus does not have a means for maintaining the seal of the passage in the state in which the check valve is shut off, the vacuum pressure of the storage space may be gradually released through the passage, so that the vacuum degree is uniform for a long time. Hard to maintain

And, the vacuum device, for example, when pumping the meat (fresh meat) containing the water contained in the interior of the packaging bag body while the water is discharged through the connection port is introduced into the pump or splashed to the outside unsanitary Can be in the state.
