Description

Cold chain broken chain detection label

Technical Field

The utility model belongs to the technical field of cold chain labels, and particularly relates to a cold chain breakage detection label.

Background

The cold chain has the function of controlling the temperature of perishable products, ensuring the safety of use of the perishable products, ensuring that the products still have good quality when purchased by consumers, and if the temperature is not controlled accurately enough, a series of products can be reduced in quality, and the products can have structural changes, color changes, damage in collision and extrusion and microorganism propagation. Every link of the cold chain, from the time the product is picked up until it is sold, requires strict control of the temperature, and every link in the chain may be prone to errors causing the cold chain to break, either on the dock of the warehouse, during transportation, during storage, or in a retail supermarket. If one link breaks, it affects the end consumer's needs. The existing cold chain temperature monitoring technology can only measure the temperature of part of links, the temperature of the product in the process of handover cannot be monitored, if the product is deteriorated due to overhigh temperature in the process of handover, the product is not easy to be perceived by people, and the final quality of the product is further affected. Although electronic tracking tags are available, professional equipment is required for identification, and the cost of the tracking tags is too high to be suitable for popularization and use.

The Chinese patent publication No. CN203772447U discloses a color-changing detection label for a cold chain, wherein a color-changing material is wrapped by a transparent film and then is adhered to a self-adhesive layer together with a porous material with capillary phenomenon, a compression switch is arranged between the color-changing material and the porous material, the self-adhesive layer is food-grade self-adhesive, and the surface of the self-adhesive layer is provided with indication scales. The color-changing detection label for the cold chain is mainly used for tracking whether the environment temperature of the cold chain product has an overtemperature problem and how much time the temperature exceeds.

Said utility model can monitor the temperature change in the course of connection, but the porous material can not be completely removed after absorbing the color-changing material, so that it can not be repeatedly used, and can result in resource waste.

As shown in fig. 1-3, a cold chain breakage detection label comprises an outer box 1 and an inner box 4, wherein the inner box 4 is arranged in the outer box 1, and the outer box 1 and the inner box 4 are in transition fit, so that the inner box 4 can be prevented from rolling in the outer box 1, and the PH test paper 2 is prevented from being separated from a through hole 6;

the top and the bottom of the inner box 4 are provided with a plurality of pointed bulges 5 which are inwards arranged in the box, and the bulges 5 can be arranged at intervals or can be closely arranged without gaps; the top and the bottom of the inner box 4 are provided with a plurality of through holes 6 (the through holes 6 can be arranged at the bottom, and the through holes 6 are arranged at the top and the bottom, so that the device can still be normally used when being overturned, if the through holes 6 are arranged at the bottom only, the bottom is required to be ensured to be downward when the device is used), the through holes 6 are used for communicating the inner part and the outer part of the inner box 4, and the through holes 6 can be directly arranged on the bulges 5 or can be arranged at intervals between the bulges 5, so long as the inner part and the outer part of the inner box 4 can be communicated;

a solution bag 7 is clamped between the top of the inner box 4 and the tail end of the bulge 5 at the bottom, and the solution bag 7 adopts a plastic film bag so as to be pierced by the bulge 5, so that the solution in the inner box flows out; the solution bag 7 is filled with acidic or alkaline salt solution, and a small amount of hydrochloric acid or NaOH can be mixed with NaCl solution; the freezing points of NaCl solutions with different concentrations are different, solutions with different concentrations can be sampled according to the needs, and different label working temperatures are set (see table 1 for details and salt water performance table);

the top of the outer box 1 is provided with an opening and a first sealing cover 3, the side wall of the inner box 4 is provided with an opening and a second sealing cover, and the two sealing covers and the corresponding openings can be in threaded sealing connection or other sealing connection modes; so that the PH test paper 2 and the solution bag 7 can be taken out and replaced as required;

the outer box 1 is made of transparent materials, so that the color change of the PH test paper can be conveniently observed from the outside; the inner box 4 can be made of transparent materials, so that the condition of the solution bag 7 in the inner box can be observed conveniently, and the inner box can be made of opaque materials; the top and bottom of the inner case 4 are made of deformable materials such as plastics, so that when the upper and lower ends of the inner case 4 are pressed, the top and bottom thereof are recessed into the case so that the protrusions 5 pierce the solution bag 7;

the PH test paper 2 is arranged between the bottoms of the outer box 1 and the inner box 4 (if the top of the inner box 4 is also provided with the through hole 6, then the PH test paper 2 is also arranged between the top of the outer box 1 and the top of the inner box 4), the PH test paper 2 faces the through hole 6, so that the solution in the solution bag 7 can be directly contacted with the PH test paper 2 to change color when flowing out, the flowing out solution is prevented from being too few, the PH test paper 2 and the through hole 6 have a certain distance, and the solution cannot be contacted with the PH test paper 2.

The working principle of the novel cold chain breakage detection label is as follows:

before use, a proper solution is packaged in a solution bag 7 (the concentration of the solution is selected according to the use temperature), and then the solution is frozen to enable the internal solution to be in a solid state (the use temperature is required to be lower than the melting point of the solution); then the solution bag 7 is put into the inner box 4, so that the solution bag 7 is clamped at the tail ends of the bulges 5 at the top and the bottom, the second sealing cover is covered, and then the upper end and the lower end of the inner box 4 are extruded, so that the bulges 5 pierce the solution bag 7; then placing the PH test paper 2 at the bottom of the outer box 1, then placing the inner box 4 into the outer box 1 (taking care that the bottom through hole of the inner box 4 is opposite to the PH test paper 2), placing the PH test paper 2 at the top of the inner box 4, also making the PH test paper 2 opposite to the through hole at the top of the inner box 4, and finally covering the first sealing cover 3; the whole device and the object to be measured are placed together, and the bottom of the outer box 1 is required to be kept or the bottom is required to be downward;

when the ambient temperature is kept below the melting point of the solution, the solution solids in the solution bag 7 cannot melt, and the solution solids cannot contact the PH test paper 2 due to the barrier of the inner box 4; when the ambient temperature is higher than the melting point of the solution, the solution is melted, and the solution flows out of the through hole 6 to be in contact with the PH test paper 2 due to the action of gravity, so that the PH test paper 2 is discolored, and whether the temperature is higher than the preset temperature in the handover process can be intuitively judged through the color of the PH test paper 2; if the condition of overhigh temperature (exceeding the preset temperature) does not occur in the handover process, the solution cannot be melted, the PH test paper 2 cannot be discolored, the whole device can be directly reused, and if the condition of overhigh temperature occurs, the PH test paper 2 and the solution bag 7 need to be replaced again for reuse.
