Abstract

The present invention relates to a method for checking freshness of milk using a pH sheet, with which consumers can drink milk by confirming the freshness of milk with eyes, thereby solving a problem that freshness cannot be confirmed so far. A milk pack comprises: a paperboard made of an outer-natural pulp made as a natural pulp paperboard to prevent milk spillage; an inner-nontoxic polyethylene made of non-toxic polyethylene for storing milk; and an inlet with the pH sheet on an existing material so that freshness can be visually confirmed. Therefore, the present invention enables the consumers to drink milk by confirming the freshness of the milk with eyes, thereby solving the problem that the freshness cannot be confirmed so far.

Description

ph시험지를 이용한 우유의 신선도 확인 방법{Milk fresh of the way to use the exam paper ph}[0001] The present invention relates to a method for checking the freshness of milk using a pH test paper,

본 발명은 ph시험지를 이용한 우유의 신선도 확인 방법에 관한 것으로서,The present invention relates to a method for checking the freshness of milk using a pH test paper,

더욱 상세하게는 우유팩에 있어서,More particularly, in a milk pack,

우유의 유출을 막을 수 있게 천연펄프 판지로 구성한 외부-천연펄프로 만든 판지, 우유를 보관 할 수 있게 무독성 폴리에틸렌으로 구성한 내부-무독성 폴리에틸렌, 신선도를 눈으로 확인 할 수 있게 기존의 재질위에 ph시험지를 부착한 입구로 구성 하여서,Inner - non-toxic polyethylene made of non-toxic polyethylene to store milk, cardboard made of natural pulp made of natural pulp paper to prevent the leakage of milk, pH test paper on the existing material to visually check freshness With the attached inlet,

우유의 신선도를 눈으로 확인함으로써 안심하고 먹을 수 있게하도록 함을 목적으로 한 것이다.It is aimed at making sure that milk can be eaten safely by checking the freshness of the milk with eyes.

일반적으로 우유팩은 우유를 보관하는 것이다.Milk packs generally store milk.

상기한 바와 같이 우유팩은 외부-천연펄프로 만든 판지, 내부- 무독성 폴리에틸렌으로 구성된 것이다.As described above, the milk pack is composed of a cardboard made of outer-natural pulp, and an inner-non-toxic polyethylene.

이상과 같은 우유팩은 우유의 변질을 막기 위해 보관하는 것이다.These milk packs are stored to prevent the deterioration of milk.

그러나 상기한 바와 같은 종래의 우유팩은 신선도 확인이 가능하지 않은 문제점이 있었다.However, the conventional milk pack as described above has a problem that freshness can not be confirmed.

대한민국 등록 제20-0447636호Korea Registered No. 20-0447636

이에 본 발명은 종래의 우유팩이 신선도 확인이 가능하지 않은 문제점을 해결하기 위한 것이다.Accordingly, the present invention is intended to solve the problem that the conventional milk pack can not confirm freshness.

즉, 본 발명은 우유의 유출을 막을 수 있게 천연펄프 판지로 구성한 외부-천연펄프로 만든 판지, 우유를 보관 할 수 있게 무독성 폴리에틸렌으로 구성한 내부-무독성 폴리에틸렌, 신선도를 눈으로 확인 할 수 있게 기존의 재질위에 ph시험지를 부착한 입구로 구성한 것이다.That is, the present invention relates to an outer-natural pulp paper made of a natural pulp paper so as to prevent the leakage of milk, an inner-non-toxic polyethylene made of non-toxic polyethylene capable of storing milk, It consists of an inlet with a pH test paper on the material.

따라서 본 발명은 우유의 유출을 막을 수 있게 천연펄프 판지로 구성한 외부-천연펄프로 만든 판지, 우유를 보관 할 수 있게 무독성 폴리에틸렌으로 구성한 내부-무독성 폴리에틸렌, 신선도를 눈으로 확인 할 수 있게 기존의 재질위에 ph시험지를 부착한 입구로 구성 함으로써, 우유의 신선도를 눈으로 확인함으로써 안심하고 먹을 수 있게하도록 한 효과를 갖는 것이다.Accordingly, the present invention relates to a cardboard made of an outer-natural pulp made of a natural pulp paper so as to prevent the leakage of milk, an inner-non-toxic polyethylene made of non-toxic polyethylene capable of storing milk, And an inlet with a pH test paper on it, thereby making it possible to reliably eat the milk by checking the freshness of the milk with eyes.
