Example

The method S100 of double-wrapping a plastic container and a metal cover according to an embodiment of the present invention includes arranging a container flange PF of the plastic container P and an upper surface of the plastic container P as shown in FIG. 1 (a), the end of the cover flange MF is bent downward and the flange MF of the cover flange MF of the metal cover M is folded downward to the inside of the bottom surface of the container flange PF (S20). ≪ / RTI >

At this time, the inside of the portion of the cover flange MF bent to the inside of the bottom surface of the container flange PF, that is, the inside of the arc-shaped bent portion is filled with the sealing material S.

Thereafter, as shown in FIGS. 1 (b) to 1 (d), the cover flange MF and the container flange PF are pressed together to form a cover flange PF, (MF) are fixed to the inside of the container flange (PF) so as to be fixed and sealed with each other.

That is, in the case of the present invention, the cover M made of a metal is used for the container P made of plastic, and the flanges formed at one end are fixed to each other by fixing them.

According to the present invention, since the container is made of a plastic material, it is possible to prevent corruption and corrosion of the contents and oxidation phenomenon of the container.

In addition, since the container is made of a plastic material as described above, the manufacturing cost can be reduced, and odor can be prevented from being generated through the odor generated in the metal can. Thus, according to the present invention, Can be solved.

In step 20, the end of the cover flange MF is bent downward and disposed inside the bottom surface of the container flange PF (see FIG. 1A). To this end, the operator manually folds the cover flange MF MF may be downwardly bent, or may be bent using a separate tool.

The sealing material S is a sealing member that seals the space between the cover flange MF and the container flange PF after the cover flange MF and the container flange PF are wound as shown. Any material that can be used is of course within the scope of the present invention.

Also, various methods and configurations can be used to perform the twenty-first step (S30), which is a double-wrapping step of simultaneously pressing the cover flange MF and the container flange PF. However, as shown in FIGS. 1 and 2 It is also possible to use the first and second rollers 110 and 120 for pressing and pressing the cover flange MF and the container flange PF together.

That is, when the first rollers 110 are disposed on one side of the cover flange MF and the container flange PF as shown in the drawing, In the direction of the container flange (PF).

The cover flange MF and the container flange PF are bent according to the contact shape with the first rollers 110 by the first rollers 110 as described with reference to FIG.

The cover flange MF and the second cover roller 120 disposed on the other side of the container flange PF after the first cover roller 110 is first wound by the first cover roller 110, The cover flange MF and the container flange PF may be secondarily wound in a manner such that the folding shape of the cover flange MF and the container flange PF depends on the contact form with the second rollers 120 as described above.

On the other hand, as described above, the cover flange MF and the container flange PF are bent by the first rollers 110 and the second rollers 120, It is also possible to carry out the tenth step S10 of supporting the plastic container P and the metal cover M as shown in Fig.

In this case, the tenth step S10 may be performed before or after the step S20.

The tenth step S10 is a step 110 of arranging the plastic container P on the lift 140 capable of vertically moving and rotating and then placing the metal cover M on the plastic container P S110).

As described above, in the present invention, the cover flange MF and the container flange PF are wound together by the first and second rollers 110 and 120, P to rotate the metal cover M.

To this end, the plastic container P is disposed on the lift 140, which is vertically transportable and rotatable, and the metal cover M is disposed on the plastic container P as described above.

After the step 110 is performed, the chuck unit 130, which is disposed on the metal cover M and is vertically movable and rotatable, is lowered while the lift 140 is lifted, P) and the metal cover (M) to each other.

That is, after the plastic container P and the metal cover M are disposed on the lift 140 in the step 110 (S110), the chuck unit 130 is lowered so that the plastic container P and the metal cover M M).

The plastic container P and the metal cover M are rotated by the lift 140 so that the chuck unit 130 is rotated as well. The chuck unit 130 is also installed so as to ascend and descend so that the chuck unit 130 is firmly fixed to each other.

After performing the above-described tenth step (S10) and then performing the 20th step (S20), or after performing the 20th step (S20), the 10th step (S10) (S30).

In operation S30, the chuck unit 130 for fixing the cover flange MF and the container flange PF, and the step S310 for rotating the lift 140 may be performed have. That is, it is preferable to rotate the plastic container P and the metal cover M so that the chuck unit 130 and the lift 140 can be lowered and lifted, respectively, as described above, And rotates the chuck unit 130 and the lift 140 in a state where the plastic container P and the metal cover M are fixed.

In operation S320, the cover flange MF and the container flange PF are firstly wound in accordance with the shape in which the cover flange PF is brought into contact with the first rollers 110 (S320) do.

For this, in step S320, the first cover roller 110 is disposed on one side of the cover flange MF and the container flange PF to rotate the first cover roller 110 in the rotated state between the cover flange MF and the container flange PF) by a predetermined distance.

That is, since both the plastic container P and the metal cover M are rotated, the cover flange MF and the container flange PF are also rotated. At this time, the first cover roller 110 is rotated and pressed to the cover flange MF and the container flange PF side.

At this time, the shape of the cover flange MF and the container flange PF is dependent on the shape of the first rollers 110 to be contacted as described above, It is natural to follow the distance.

The first cover roller 110 is separated from the cover flange MF and the container flange PF after the cover flange MF and the container flange PF are firstly wound by the above-described Step 320 (S320) (Step S330).

Then, in operation S340, the cover flange MF and the container flange PF are secondary-wound according to the shape in which the cover flange MF and the container flange PF are in contact with the second rollers 110, respectively.

In operation S340, the second cover roller 120 is disposed on the other side of the cover flange MF and the container flange PF and is in a rotated state, similar to step S320. So that the cover flange MF and the container flange PF side are pressurized by a certain distance to be secondarily wound.

An apparatus 100 for winding the cover flange MF and the container flange PF by the method of the present invention and for carrying out the above-described winding method described above with reference to Figs. 3 to 5 will now be described.
