It is noted that, in the drawings, the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The air bag 100 of the present invention includes the air bag 120 and the air bag 120. The air bag 120 is wound around the air bag 120 and sucks air in the bag 130 to compress and seal the air bag 120, (101), blowing the case (110) by inserting the inner filling body (101) into the blow mold (E), and blowing the plastic bag inside the blow molded case 130 to form an air hole so that the air cell sheet 120 is inflated inside the case 110 and sealing the inside of the case 110 by blocking the through hole 111 of the case 110 .

The case 110 has various shapes such as a spherical shape, a cylindrical shape, and a square shape for forming a space portion therein. As a result, the air cell sheet 120 is filled in the space portion of the present invention, so that the air cell sheet 120 acts as a sphere.

The air cell sheet 120 is made of a thermoplastic elastomer material made of PP or PE. The upper sheet and the lower sheet are sealed by a known means and a method, A plurality of air cells 120a into which air is injected are formed and protruded toward one side or both sides. At this time, the air cell sheet may have an air cell sheet having various structures such as a size and a number suitable for the purpose of use.

When the air cell sheet 120 is used as an inner filling material of the present invention unit 100, the air cell sheet 120 is laminated or rolled up and filled in the space. At this time, the air cell sheet 120 must be filled to the extent that the space can be filled.

This is for the purpose of achieving the maximum buoyancy and functioning properly as a buoy, but it is not enough to simply stack the air cell sheet 120 in the space or to roll it in.

Accordingly, the present invention is configured such that the air cell sheet 120 is curled and the air bag 120 is accommodated in the plastic bag 130 to suck air in the plastic bag 130 to fill the space. At this time, the suction of the air is performed by inserting the vacuum suction pipe A into the inlet of the plastic bag 130 and sucking the air inside the plastic bag 130 by a vacuum suction device (not shown) And then the inlet of the plastic bag 130 is bundled with a binding strap B to be sealed. As a result, the air cell sheet 120 is reduced in size and kept in a reduced state.

It is also possible to wrap the inner filling body 101 in the reduced state by the plastic bag protecting sheet 140 and insert the inner filling body 101 into the blow mold E. This is because the plastic bag 130 constituting the inner filling body 101 is blow- This is to prevent melting of the hand (C) at high temperature. That is, when the parison bag C is cooled after the blow molding and is melted in the high temperature of the parison C before the shape of the parison bag C is maintained, the plastic bag 130 is blown, This is because sudden expansion causes difficulty in proper blow molding.

Therefore, it is a matter of course that the material of the plastic bag protective sheet 140 should be such that the material does not dissolve in the high temperature of the parison C. [ Of course, it is natural that the present invention can use a plastic bag 130 that does not dissolve in the high temperature of the parison C, As the plastic bag protective sheet 140, a thin synthetic resin plate is preferable, and the plastic bag is resilient, and the adhesive tape 141 is attached so as to prevent the plastic bag protective sheet 140 having elasticity from spreading in an undesired state .

At this time, the adhesive tape 141 is sufficient to release the vacuum state of the plastic bag 130 by piercing the plastic bag 130 so that the airgel sheet 120 is adhered to the inflation pressure when it expands.

The inner filling body 101 is inserted into the traction line D at the middle portion of the parison C so as to be located at the middle portion of the parison C when the inner filling body 101 is inserted into the blow mold E. [ It is preferable to hang it so that it does not move.

When the case 110 is blow-molded, a hole is formed in the plastic bag 130 to release the vacuum state so that the air cell sheet 120 can be inflated. At this time, a method of puncturing the plastic bag 130 The plastic bag 130 may be naturally formed in the parison C so that air holes may be formed in the parison C or the operator may forcibly insert the air hole 111 formed in the case 110, An air hole may be formed in the plastic bag 130 by inserting the anchor G through the through-

When a hole is formed in the plastic bag 130, the air cell sheet 120, which has been significantly smaller than the size of the plastic bag 130, is inflated to fill the inside of the case 110, that is, the space. When the internal filling body 101 is reduced to a size 20 to 30% smaller than the normal size and then expanded to the original size within the space of the case 110, the air cell sheet is inserted into the case 110 It is possible to prevent the present invention part 100 from being crushed by an external impact and to have a good buoyancy.

Lastly, the through hole 111 of the case 110 is plugged or melted with the stopper 150 to seal the inside of the case 110, thereby completing the entire process for manufacturing the mouthpiece 100 of the present invention.

Although the present invention having been described above has been described with reference to a limited number of embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications may be made without departing from the spirit and scope of the present invention by those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
