Description

Vacuum packing bag

The present invention can store a variety of foods and foods in a vacuum state that can maintain the freshness, and more particularly relates to a vacuum packaging bag to obtain improved operation convenience and vacuum degree.

In general, a vacuum packaging bag (also called a "zippered bag") is mainly used for storing various foods or foods, and in particular, it can be stored in a vacuum state and thus has an advantage of maintaining freshness for a long time.

Briefly describing the structure of the vacuum packaging bag, a packaging bag body having a storage space, and a female / male zipper, and is configured on the packaging bag body side to open or block one side of the storage space. It is formed to include an opening and closing zipper.

In addition, a valve corresponding to the accommodation space is attached to one side of the packaging bag main body, and the valve has a structure of a conventional check valve (or one-way valve) type.

That is, when the pump is pumped in a state in which the pump is connected to the outside of the bag, the valve opens a passage so that the air in the storage space is forced out by the suction input, and blocks the passage when the pumping stops.

In particular, it is important for these vacuum packaging bags to form the storage space of the packaging body main body quickly and simply by a simple operation using a pump.

However, the above vacuum packaging bags may cause various problems when the storage space of the packaging body is formed in a vacuum state.

That is, by simply pumping in a state in which the pump is connected to the valve side, it is difficult to quickly make the storage space of the packaging bag main body into a vacuum state.

For example, when forcibly discharging the air in the storage space by pumping of the pump, the front and rear surfaces of the main body of the packaging bag around the valve stick to the surface contact state by suction force, so that the space around the valve is blocked in the storage space. Symptoms (bottlenecks) may occur.

In such a state, it is difficult to quickly form the entire storage space in a vacuum state, and even if the pump is continuously pumped, the remaining portion of the storage space cannot be formed in a vacuum state.

Furthermore, when the front and rear of the packaging bag body are stuck together as described above, when the valve surroundings are blocked, the vacuum is released, and then pumping is performed again from the beginning, and the operation is cumbersome and takes excessive time.

Therefore, the conventional vacuum packaging bag is difficult to quickly form the inside of the packaging bag body in a vacuum state, and satisfactory operation convenience cannot be expected.

In order to remedy this problem, for example, the front and back of the packaging bag body is embossed in a conventional manner to form a plurality of projections to face the storage space and the gaps are secured by these projections. Is being presented.

However, the method of embossing the thin wrapping paper of the front and back of the packaging bag body as described above may cause another problem.

For example, the thin wrapping paper surfaces on the front and back sides of the packaging bag body may have a markedly reduced durability by embossing.

Therefore, the wrapping paper of the packaging bag main body may be easily damaged due to the pressure or external contact and friction acting when the storage space is formed in a vacuum, which may be a factor that degrades the merchandise.

In addition, the projections embossed by pressing the soft wrapping paper cannot expect satisfactory bearing capacity in response to external contact or pressure, so that a smooth gap is secured between the front and back of the packaging bag body when the storage space is formed in a vacuum state. Difficult to do
