DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressible sealing bag for a compressible material provided with a closure at an opening.
In a compressible sealing bag of a compressible material in which at least two male and female strip fasteners for sealing opposed to the inner surfaces on both sides of the periphery of the opening are arranged side by side, the male and female strip fasteners are easily and securely engaged and opened. The present invention relates to a compression-sealed bag of a compressible material provided with a closure having an advantage that a part can be sealed.

[0002]

2. Description of the Related Art Conventionally, in order to seal the openings of various types of sealing bags, male and female strip fasteners for sealing, which are opposed to the inner surfaces on both sides of the edges of the openings, have been used to attach male bands. The enlarged head of the strip fastener was partially press-fitted into the groove of the female fastener with a fingertip, and was tightened with the fingertip over the entire length of the strip fastener.

[0003]

However, the above-mentioned engaging operation by the fingertip is considerably difficult, and the part which is once engaged is likely to come off or an incomplete engaging state is likely to occur. Is more likely to occur as the length of the fastener is longer,
In particular, in the case of a double fastener in which two opposite male and female strip fasteners are arranged side by side, there is a problem that the engaging operation is more difficult, and incompletely engaging parts are likely to occur frequently.

[0004] The problem is that the sealing bag is provided with a check valve on the periphery other than the opening to release the fluid such as air in the compression sealing bag main body to reduce the bulk. In the case of a compression-sealed bag of a compressible material, a particularly serious problem is caused. For example, if the incompletely engaged portion is even one place, when the fluid inside the bag body is discharged from the check valve to the outside by pressurizing the compression-sealed bag body, the detached portion spreads widely and outside air flows in. However, there is a problem that the complicated sealing work must be repeatedly performed many times to immediately lose the reduced sealing effect of the package. There is a problem that the outside air flows into the bag body at a time, and the reduced sealing effect of the package is lost in the same manner as described above.

The present invention has been developed with the object of solving the above-mentioned problems, and comprises at least two male and female strip fasteners arranged side by side with a predetermined spacing therebetween. Provided is a compression-sealed bag for a compressible material having a check valve and having an opening closure which has an advantage that the male and female strip fasteners can be easily and securely engaged. The purpose is to:
