FIG. 6 is a cross- FIG. 7 is a process diagram of vacuum packaging using the vacuum packaging machine according to the first embodiment of the present invention. FIG.

First, in the case where the plastic bag 40 is sealed or heat-sealed without vacuuming the inside of the plastic bag 40, the procedure shown in FIG. 5 is performed.

The cover portion 20 is opened and the pressing portion 35 is rotated upward to open the upper portion of the heater 11 as shown in FIG. 5 (a).

In this state, the plastic bag (40) can be freely arranged on the upper portion of the heater (11).

Then, as shown in FIG. 5 (b), the pushing portion 35 is rotated downward so that the other end of the pushing portion 35 is inserted into the attaching / detaching groove 34 of the second support block 33.

Until this time, power is not applied to the heater 11.

The lower surface of the pressing portion 35 may directly press the plastic bag 40 when the pressing portion 35 is rotated downward. In this case, 35 and the heater 11 are spaced apart from each other by the spring 15 so that the plastic bag 40 is not yet pressed.

Then, as shown in FIG. 5 (c), the user pushes down the pushing portion 35 in the downward direction.

The pressing portion 35 is lowered while the spring 15 is compressed and the plastic bag 40 positioned at the lower portion of the pressing portion 35 is pressed between the pressing portion 35 and the heater 11 .

When the pressure is automatically applied to the heater 11 simultaneously with the descent of the pressure member 30 or after the descent of the pressure member 30 by the user's operation, The plastic bag 40 is thermally fused by the heater 11 because the plastic bag 40 is pressed against the heater 11 while being pressed by the unit 35. [

In the absence of the spring 15, the pressing member 30 is lowered by gravity and presses the plastic bag 40.

At this time, the opening portion of the plastic bag 40 may be open or wrinkled by food or the like inside. The pushing portion 35 presses the opening of the plastic bag 40 in the downward direction in which the heater 11 is disposed The opening of the plastic bag 40 is opened without being folded.

When the thermal sealing of the plastic bag 40 is completed, the user places the pressing portion 35 thereon.

Then, the pressing portion 35 is raised by the resilient restoring force of the spring 15 that has been compressed.

At this time, power is not applied to the heater 11 any more.

Thereafter, the pushing portion (35) is rotated upward to take out the thermally fused plastic bag (40).

In the absence of the spring 15, the pushing portion 35 is rotated upward to take out the thermally fused plastic bag 40.

As described above, according to the present invention, since the plastic bag 40 can be thermally fused by the pressing member 30 which is raised and lowered independently from the cover member 20 in the state that the cover member 20 is opened, 6, the plastic bag 40 may be divided into a plurality of sections and thermally fused to the plastic bag 40, as shown in FIG. 6, by freely positioning the plastic bag 40 in a state where the member 20 is opened. Can be accurately determined.

On the other hand, when the inside of the plastic bag 40 is to be vacuum-sealed and thermally fused, the procedure shown in Fig. 7 is performed.

At this time, the opening of the plastic bag 40 is positioned inside the chamber 12.

Thereafter, as shown in Fig. 7 (b), only the pressing portion 35 is rotated while the cover member 20 remains, and the other end of the pressing portion 35 is coupled to the second supporting table 33 .

This state is the same as that shown in Fig. 5 (b).

As a result, the plastic bag 40, in which the opening portion is opened by internal food or the like, is in a state in which the pressing portion 35 is deployed almost in an expanded state because it is pressing the opening portion of the plastic bag 40, The opening of the plastic bag 40 is stably disposed inside the chamber 12 by the frictional force between the plastic bag 40 and the plastic bag 40.

Thereafter, as shown in Fig. 7 (c), the cover member 20 is rotated downward to be closed.

At this time, the front of the cover member 20 is positioned above the pressing member 30.

7 (d), when the user presses the cover member 20 in this state, the pressing member 30 also descends due to the falling of the cover member 20. As shown in FIG.

At this time, the chamber 12 is sealed and the plastic bag 40 is pressed between the pressing portion 35 and the heater 11.

When the vacuum pump 16 operates in this state, the air inside the plastic bag 40 is discharged to the outside through the chamber 12 and the vacuum pump 16, and it is judged that the inside of the plastic bag 40 is evacuated The power is applied to the heater 11 and the opening of the plastic bag 40 is thermally fused and sealed.

The operation of the vacuum pump 16 and the heat sealing of the plastic bag 40 can be accomplished by using a known technique, and a detailed description thereof will be omitted.

As described above, in the present invention, since the pressing member 30, which is formed separately from the cover member 20, is a constituent element, the cover member 20 is opened and the plastic envelope 40 The user can easily heat-seal the plastic bag 40 while viewing the position of the plastic bag 40 directly.

Further, since the pressing member 30 stably presses the plastic bag 40 while the opening of the plastic bag 40 is disposed in the chamber 12, the plastic bag 40 flows, Can be prevented from being detached from the chamber (12).

Therefore, it is not necessary to form the length of the plastic bag unnecessarily long in order to arrange the opening portion of the plastic bag deeply in the chamber as in the prior art, because the thermal sealing of the opening of the plastic bag and the vacuum packaging can be accurately and easily performed without fail Waste of expensive plastic bags for vacuum packaging can be reduced.
