Description

A visual preservation box for meat freshness

technical field

The utility model relates to the technical field of fresh-keeping boxes, in particular to a visual fresh-keeping box for meat freshness.

Background technique

With the process of social urbanization, more and more consumers choose to go to the supermarket to buy boxed chilled meat. Boxed chilled meat can effectively prolong the shelf life of fresh meat and prevent the growth of bacteria and other problems, and is safer than fresh meat that is directly exposed for sale. The freshness of fresh meat is directly related to the nutritional value of the meat. The longer the fresh meat is stored, its nutritional content will have a significant downward trend, and it may even breed bacteria and corruption, resulting in potential food safety hazards. Under normal circumstances, merchants and consumers can directly judge the freshness of meat through color, smell and touch, and then judge whether fresh meat is fresh and whether it can be sold and purchased. However, due to the sealed packaging of boxed fresh meat, it is impossible to directly judge whether the meat is fresh by smell and touch. As a result, many consumers have scruples about the purchase of boxed fresh meat for the above-mentioned reasons when they buy boxed fresh meat in supermarkets.

Therefore, it is of great significance to design a fresh-keeping box that can visually display the freshness of meat, which can effectively improve people's purchasing tendency for boxed chilled meat. It can also store fresh meat very well to prevent fresh meat from spoiling.

Utility model content

The purpose of the utility model is to improve and innovate the shortcomings and problems existing in the background technology, and to provide a visual fresh-keeping box for meat freshness.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a meat freshness visual fresh-keeping box, including a fresh-keeping box, a fixing frame is installed on the inner wall of the fresh-keeping box, a detection test paper is placed in the fixing frame, and the side wall of the fixing frame is installed. A number of strip grooves are opened, and a first groove is opened on the side wall of the fresh-keeping box located at the fixing frame. A mounting plate is installed in the first groove, and the mounting plate is a transparent plastic plate. A through groove communicated inside the fixing frame, a ring of sealing strips is arranged on the inner side of the mounting plate, and a second groove corresponding to the sealing strip is opened on the first groove.

A further solution is that handles are installed on both sides of the outer surface of the mounting plate, inserting rods are fixedly connected at the four corners of the inner side of the mounting plate, annular bumps are installed on the outer surface of the inserting rod, and four corners of the first groove are provided with inserting rods. A straight groove corresponding to the rod, the straight groove includes a first inner wall and a second inner wall, the first inner wall is in clearance fit with the annular projection, and the second inner wall is in interference fit with the annular projection.

A further solution is that the straight groove further includes a third inner wall, the third inner wall is a variable diameter section arranged between the first inner wall and the second inner wall, and the diameter of the third inner wall is from the diameter close to the first inner wall. from one end to the end close to the second inner wall gradually narrows.

A further solution is that the detection test paper is a lead acetate alkaline test paper, and the lead acetate alkaline test paper is stuck on the bottom wall of the fixed frame by double-sided adhesive.

Compared with the prior art, the beneficial effects of the present utility model are: (1) the fresh-keeping box has the same functions of refrigerating and fresh-keeping meat as the general fresh-keeping box, and a fixed frame for accommodating the detection test paper is also designed, which can be observed through observation. The color change of the test paper can judge the freshness of the meat;

(2) The test paper matching the fresh-keeping box is fixed in the fixed frame, which can test the freshness of the meat and completely isolate the contact with the fresh meat, effectively ensuring the safety of the fresh meat;

(3) Squeeze the mounting plate forcefully. When the annular bump passes through the first inner wall and the third inner wall in turn and enters the second inner wall, the sealing strip will be squeezed at the same time, so that the sealing strip and the second groove are tightly fitted , the sealing strip has a good sealing effect, effectively avoiding the air circulation between the fixed frame and the external environment.

Detailed ways

The present utility model will be further described in detail below in conjunction with accompanying drawings 1-5.

A visual fresh-keeping box for meat freshness, comprising a fresh-keeping box 1, a fixed frame 6 is installed on both sides of the inner wall of the fresh-keeping box 1, and a detection test paper is arranged in the fixed frame 6, and the detection test paper is lead acetate alkaline test paper, acetic acid After the lead alkaline test paper reacts with hydrogen sulfide gas, lead sulfide is formed, which makes the color of the test paper black. The side wall of the fixing frame 6 is provided with a plurality of strip-shaped grooves 7 , and the strip-shaped grooves 7 make the interior of the fresh-keeping box 1 communicate with the interior of the fixing frame 6 . The side wall of the fresh-keeping box 1 located at the fixing frame 6 is provided with a first groove 12, and a mounting plate 2 is installed in the first groove 12. The mounting plate 2 is a transparent plastic plate, and the middle of the first groove 12 is provided with a The interior of the fixing frame 6 communicates with the through groove 8 , the inner side of the mounting plate 2 is provided with a ring of sealing strips 4 , and the first groove 12 is provided with a second groove 9 corresponding to the sealing strip 4 .

In this embodiment, handles 3 are installed on both sides of the outer surface of the mounting plate 2 , and the handles 3 are easily disassembled from the side wall of the fresh-keeping box 1 by holding the handles 3 . The four corners of the inner side of the mounting plate 2 are fixedly connected with the insertion rod 5, the outer surface of the insertion rod 5 is provided with an annular bump 11, and the four corners of the first groove 12 are provided with straight grooves 10 corresponding to the insertion rod 5. The groove 10 includes a first inner wall 13, a second inner wall 14 and a third inner wall 15, the third inner wall 15 is a variable diameter section arranged between the first inner wall 13 and the second inner wall 14, and the diameter of the third inner wall 15 is from The end close to the first inner wall 13 gradually narrows to the end close to the second inner wall 14 .
