Description

Method for manufacturing container of multi-stage lamination type and its structure {omitted}

The present invention relates to a container manufacturing method and a structure of a multi-stage stackable form, the prior art is US Patent 4,714,164 and 4,761,156.

Conventional cup-shaped containers have a monotonous closure in terms of function or design, such as treating the upper part with a thin plate or treating a lid-like finish separately.

In addition, as a more advanced, different finishes were induced, such as highlighting the design by overlapping the separate finishing portion on the upper portion of the container, but this has the disadvantage of causing waste pollution as excess packaging.

In order to overcome the above disadvantages, generally known carton packs are used a lot. As a disadvantage of this, in order to apply the carton packs, a separate carton pack molding apparatus must be provided at the corresponding workplace, and this is applied in a small workplace. It was difficult to do.

Of course, if you go to the carton pack factory to form the bottom of the carton pack and transfer to the workplace, there is no problem, but in this case there is a waste of excessive logistics costs.

The carton pack is folded and transported to the top and bottom of the unmolded body, the logistics cost is reduced, but when forming a portion of the carton pack as described above, the carton pack turns into a three-dimensional shape to occupy a large volume Because.

The above reason is that the carton pack cannot be structurally laminated in multiple stages.

In order to solve the above disadvantages, the above-mentioned US patents 4,714,164 and 4,761,156 have been proposed.

The above-described US patent is to enable a multi-stage lamination to achieve a pleasant overcoming of the above disadvantages.

However, as a problem, in order to prevent the occurrence of vacuuming between containers during stacking, a problem arises in that a vacuuming step must be prevented.
