Description

Strawless Packaging Container and Its Eco-friendly Designed Detachable Structure of Carton Package and Copolymer Film

The present invention relates to a paper pack, and it is possible to suck in the liquid fluid as the contents through an ejection port made by removing the fold located on the upper part of a rectangular parallelepiped paper container in a form that omits a plastic straw, and it is a component of an existing carton, an external paper packaging material and an internal low density A technology that facilitates detachment between interior and exterior materials by pulling a paper string connected to the hinge portion added in the present invention to the bonding form of polyethylene (LDPE) or a copolymer sterilized packaging material similar to that It relates to applied cartons.

The commonly used sterile paper container in the form of a rectangular parallelepiped is 'Packing container and a laminate for its manufacture' (European extinction patent EP.0011348.B1, US extinction patent 04267957) and ' Packing containers with pouring spout' (European expiry patent EP.0018694.B1 US expiry patent 04301927), a plastic penetrating a small silver foil circle located on the surface of the carton packaging material to secure the convenience of ingestion. By intubating a straw, it was possible to create an ejection port that could easily consume the drink inside.

However, disposable plastic straws do not decompose in their natural state and are of little recycling value, so they are thrown away as general waste. It is a serious threat to the ecology as it is eventually ingested again by humans, the final predator, in the state of microplastics, as well as to wildlife, such as being caught in the nose of sea turtles.

Accordingly, the Ministry of Environment of the Republic of Korea announced the results of the “Circular Usability Evaluation ('18~'19) for Yogurt, Cup Coffee, and Sterile Packs, etc.” It is recommended to be attached, and regulations on straws are being strengthened in countries around the world.

To this end, an evasive technology came out in the form of covering the exterior with a protruding stopper instead of a straw, but due to the characteristics of the market for small paper containers of around 180-220ml, which is the target of the present invention, there are about 16-24 paper containers in one paper carton pallet. It has not been commercialized due to the limitation that it must have a rectangular shape of uniform size because it must be densely packed and distributed in large quantities.

For example, a famous coffee brand tried to supply straws with biodegradable materials such as paper straws after the relevant administrative notice, but the function was lost due to deformation or condensation or direct contact generated during the inhalation of liquid beverages (especially in the case of cold drinks in summer). There is a problem of loss, so after trial and error, the trend is to introduce a 'strawless storage container' so that the contents can be ingested through the lid of the lid.

In addition, current cartons have a separate label for 'paper pack', which is neither 'paper' nor 'plastic' or 'vinyl', even when separate collection for recycling. are speculating From the point of view of the resource recycling company that collects this, the manual sorting of paper and polyethylene film again caused an increase in recycling costs and a decrease in the quality of recycled materials.

In the present invention, in order to solve the above problems, the method of separating the front and back surfaces of the exterior material and separating the front and back surfaces of the exterior material is a method in which the contents can be easily drunk without the straw in the conventional paper pack. In order to remove the .U triangular gimbap or sandwich film packaging, the red band in the middle was rotated one turn to remove it, and then both sides were pulled to remove the packaging material from the storage container.

The present invention is to improve the conventional carton by adding a function to enable the intake of the internal fluid in the rectangular carton itself to omit the straw, and to make a cut surface so that the paper on the outer surface of the carton and the copolymer in the inner can be easily disassembled.

In the present invention, when the specific edge 11 of the rectangular parallelepiped paper container 2 is bent, the ejection port 14 can be cut by pulling it downward without a cutting tool such as scissors, so that the built-in lead ( 32), you can directly put the drink inside the carton to your mouth and eat it without a straw.

In addition, the remaining hinge portion 13 of the paper container after feeding is performed by applying a force upward, and the paper string 21 connected to the entire exterior material is removed from the container body in the order of top, rear, bottom, and front, and the paper container exterior is placed on the seat surface ( 22) and the right side (23), allowing separation from the interior material (3).

By omitting the attached straw, it is possible to keep the convenience of eating processed beverages in containers such as milk as before, without making a separate plastic by-product, and to store the contents in a sterile state for a long time, which is the original purpose of the packaging container.

It has the effect of facilitating the recycling process by making it easy to separate the outer carton pack part of the carton pack and the inner low-density polyethylene or the sterile packaging part made of a copolymer material with similar characteristics.

It has the potential to be used as a beverage storage container such as milk cartons, soymilk packs, or pack soju with uniform dimensions and capacity. The fact that it is compatible with the existing paper carton pallet standard as it is because it maintains the shape of a quadrilateral unlike the invention of a new external appearance or covered with a protruding stopper increases the industrial applicability of the scalability of the present invention. At the same time, it opens the possibility of replacing a polyethylene pouch-type container such as a coffee bag with a paper container (refer to FIG. 4) in that it can easily make an ejection port without tools, which is a difference from similar patents.

However, as the carton production line and manufacturing process have been partially changed, additional capital input from the producer is required, but based on the time of filing, the deterrence against the use of plastics is enacted in consideration of the recommendations made through consecutive government notices or the seriousness of environmental pollution. Considering the possibility of legal and economic sanctions, the utility of omitting straws and easy recycling is expected to reach the break-even point (BEP) of individual producers and to reduce social costs in terms of utility.

It is expected that it will be possible to contribute to the dissemination of eco-friendly sterilized paper containers and to solve the environmental pollution problem by implementing the technology through the prompt technology disclosure of the present invention and the transfer of technology to manufacturers and distributors capable of the production process.
