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 container has a monotonous closure in terms of function or design, such as treating the upper portion with a thin plate or a lid-shaped 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 is changed to a three-dimensional shape to occupy a large volume Because.

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

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, there has been a problem that the steps of preventing the evacuation have occurred in order to prevent the formation of the evacuation shape between the containers at the time of lamination.

In addition, the laminated pottery bar was made as a feeder, and when necessary, a closed end that needs to be attached to a separate stopper occurred.

In addition, the laminated container has a disadvantage in that the water is permeated to the portion where the feed is connected to the portion where the feed is connected, thereby degrading the quality of the product.

In addition, the stacked container is a non-product, and when the lid is formed in the container, there is a waste end to remove the lid when recycling.

In addition, the feeder container is not environmentally friendly due to the coating of synthetic resin for waterproofing.

An object of the present invention is to produce a laminated container into a single molded body by an injection molding method.

In addition, the injection molding method of the present invention is to provide a container excellent in hermetic sealing other parts other than the upper portion is another object.

In addition, the injection molding method of the present invention is another object to add the convenience of opening by integrating a stopper to the container as needed.

In addition, the injection molding method of the present invention has another object of providing a technique in which the vacuum bar is integrally formed and the container is separated very well.

In addition, the injection molding method of the present invention is another bar to provide a container that can be identified by the naked eye, the transparent material is possible.

In addition, the container produced by the injection molding method of the present invention is another object to provide an advantage that can be refilled.

In addition, the container produced by the injection molding method of the present invention is to provide a container that can be applied to various types of beverages, such as juice, when the material is heat-resistant.
