Problems solved by technology

[0005] The above scheme judges whether the milk has deteriorated by detecting the change of milk pH, but this method is not accurate, because in many cases the total number of bacterial colonies or coliforms has exceeded the standard, but the pH does not change significantly, and the pH changes when the mold reproduces Also very small, this way of detecting pH is obviously unreasonable
And every time you judge whether the Year of the Ox has deteriorated, you need to use a test paper to dip milk for comparison, which is troublesome

Embodiment 1

[0035] Such as figure 1 As shown, a milk box includes a box body 1 and a straw 2 bonded to the side of the box body 1 , and the box body 1 is provided with a suction hole for the insertion of the straw 2 .

[0036] Such as figure 2 As shown, in order to be able to intuitively and accurately judge whether the milk in the box body 1 has deteriorated, the box body 1 is provided with a deterioration indicating mechanism, which includes three discoloration zones 3, and the three discoloration zones 3 are located in a rectangular parallelepiped In the transparent box 5 of shape, transparent box 5 is positioned at the opening that offers on box body 1, and the peripheral side of transparent box 5 is integrally sealed with box body 1, and transparent box 5 is made of aluminum foil towards the side of box body 1 inside. The three discoloration zones 3 are sequentially filled with irreversible temperature-changing inks with temperature ranges of 5-25°C, 5-30°C, and 5-35°C.

Embodiment 2

[0042] Such as image 3 As shown, a milk box is different from Embodiment 1 in that the transparent box 5 is disc-shaped, the discoloration zone 3 is located in the transparent box 5, and the color comparison card 4 is also ring-shaped and surrounds the transparent box 5. week side. Correspondingly, the color comparison card 4 is provided with six different color bars, which correspond to the color changes of the three irreversible temperature-changing inks, so that the observer can accurately and quickly determine whether the milk has deteriorated and the degree of deterioration.

Abstract

The invention discloses a milk carton, and relates to the technical field of milk packing. The milk carton comprises a carton body and a straw glued to the side surface of the carton body, a metamorphic indication mechanism is arranged on the carton body, the metamorphic indication mechanism comprises at least three or more color change intervals, the non-reversible-temperature-changing ink with the different temperature intervals are filled into the at least three of color change intervals, and a color control card is printed on the side, located on each color change interval, of the carton body. By arranging the non-reversible-temperature-changing ink and the color control cards, the result of whether the milk is deteriorated can be intuitively and accurately obtained.

Description

technical field [0001] The invention relates to the technical field of milk packaging, more specifically, it relates to a milk box. Background technique [0002] There are a lot of cartoned milk in the market. Cartoned milk is generally made of cartons. There is a straw inlet on the top side of the carton. The carton is filled with milk. There is a straw plastic bag pasted on the outside of the carton, and the straw is built into the straw plastic bag. Inside, when you need to drink milk, tear off the plastic bag of the straw, take out the straw and insert it into the carton through the inlet of the straw for sucking. [0003] The storage condition of boxed milk is normal temperature storage, that is, 5-25°C, and the shelf life is generally 6 months. The temperature condition of 5-25°C can be guaranteed during the milk production process and transportation process, but the milk is sold in supermarkets , are placed directly in the external environment. In some areas, the su...
