Description

Spout pouch made from eco-friendly materials

[0001] The present invention relates to a spout pouch, and more particularly, to a spout pouch using an eco-friendly material.

[0002] Spout pouches are more flexible and economical than plastic bottles (tubs) or glass bottles, and can be manufactured in various shapes. As such, they are one of the fastest-growing packaging forms used as convenient disposable containers for health foods, supplements, and beverages, and their market share is steadily increasing.

[0003] However, the typical spout pouch consists of a vinyl airtight container, a plastic straw, and a plastic lid, which makes it difficult to recycle plastic and vinyl, and there are serious problems of environmental pollution caused by the use of plastic.

[0004] In addition, spout pouches have health issues because they use injection plastic material as a direct contact point without any other alternatives, even though the contents are food.

[0005] The present invention is intended to solve the above problems, and aims to provide a spout pouch in which the materials of the sealed container and the stopper are formed from eco-friendly materials, thereby minimizing the use of plastic.

[0006] The purpose of the present invention is not limited to the purpose mentioned above, and other purposes not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0007] In order to achieve the above-described purpose, a spout pouch using an eco-friendly material according to a preferred embodiment of the present invention is characterized by including a sealed container having an internal space formed therein and an inner surface coated with a material harmless to the human body, an injection port provided on one side of the sealed container for injecting or discharging contents into the internal space of the sealed container, and a stopper inserted into the injection port, the insertion portion of which is formed in a shape corresponding to the shape of the inner side of the injection port.

[0008] In addition, the airtight container is characterized by being made of eco-friendly paper materials including kraft paper and tieback.

[0009] In addition, the material coated on the inner surface of the sealed container is characterized by being at least one material among paraffin, thin aluminum film, low density polyethylene (LDPE), cast polypropylene, polylactic acid, and polybutylene succinate, which are harmless to the human body.

[0010] Additionally, the stopper is characterized by being made of wood or cork.

[0011] The present invention can have the effect of reducing environmental pollution by reducing the use of vinyl and plastic materials by more than 90% by forming the material of the airtight container from paper and forming the stopper from wood or cork.

[0026] Referring to FIGS. 1 and 2, a spout pouch (1) using an eco-friendly material according to the present invention can reduce environmental pollution by reducing the use of vinyl and plastic materials by more than 90% by forming a sealed container (100) and a stopper (300) using eco-friendly materials. In addition, a spout pouch (1) using an eco-friendly material can include a sealed container (100), an injection port (200), and a stopper (300).

[0027] The sealed container (100) may have an internal space formed by joining the periphery, and may be provided with an injection port (200) on one side. The material of the sealed container (100) may be an environmentally friendly paper including kraft paper, Tyvek, etc., and the inner surface may be coated with one or more materials harmless to the human body including paraffin, a thin aluminum film, low density polyethylene (LDPE), cast polypropylene, polylactic acid, and polybutylene succinate. Accordingly, the contents of food, beverage, etc. inside the sealed container (100) can be prevented from being absorbed into the sealed container (100), and the strength of the sealed container (100) can be improved.

[0028] An injection port (200) may be provided on one side of a sealed container (100) and may inject or discharge contents into or from the internal space of the sealed container (100). The injection port (200) may be inserted into a stopper (300), thereby preventing contents stored in the internal space of the sealed container (100) from being discharged. At this time, the injection port (200) may be formed in a shape corresponding to the shape of the insertion portion (310) of the stopper (300), and in one embodiment, a screw thread may be formed on the inside.

[0029] The stopper (300) can be inserted into the injection port (200) and can prevent the contents stored in the internal space of the sealed container (100) from being discharged. The material of the stopper (300) can be formed of wood or cork, and can be coated with paraffin or a thin aluminum film that is harmless to the human body and coated on the inside of the sealed container (100) to prevent contamination of the contents stored inside the sealed container (100). At this time, the entire stopper (300) can be coated, or only the insertion portion (310) inserted into the injection port (200) can be coated.

[0030] The plug (300) can be formed in a shape corresponding to the shape of the inside of the injection port (200), and in one embodiment, a screw-shaped groove can be formed.

[0031] Here, the shape of the inside of the injection port (200) and the plug (300) insertion port (310) is shown in the drawing of the present invention as having a screw thread shape applied, but is not limited thereto, and may be replaced by any means that can prevent the contents stored in the internal space of the sealed container (100) from being discharged by blocking the injection port (200) using the plug (300), such as a method of forming it into a cylindrical shape and then fixing the plug (300) using a paper sticker, or a method of inserting it in a force-fit shape.

[0032]

[0033] According to the above configuration, a spout pouch (1) using an eco-friendly material can have the effect of reducing environmental pollution by reducing the use of vinyl and plastic materials by more than 90% by forming the material of the sealed container (100) with paper and forming the stopper (300) with wood or cork, and can provide a container that is harmless to the human body.

[0034]

[0035] The present invention is not limited to the specific preferred embodiments described above, and anyone with ordinary skill in the art to which the invention pertains can make various modifications without departing from the gist of the present invention claimed in the claims, and such modifications are within the scope of the claims.
