Description

[0001] The present invention relates to a development material unit, a temperature time table including the same, and a method of activating the temperature time indicator,

Foods and pharmaceuticals that require refrigeration and refrigeration are in need of proper management due to the advancement of the refrigeration and refrigeration industry. In particular, foods such as dairy products, fish and fruits that require thorough temperature control in the distribution process are distributed from producers to consumers It should always be kept fresh throughout the process. In addition, medicines should be maintained and maintained at an appropriate storage temperature.

However, the consumer in the final consumption stage can only determine by visual observation whether the food is in an appropriate refrigeration and freezing state at the purchasing stage, and determines whether the food has been stored at the proper temperature during the whole distribution process There is a problem in that it can not be done. Furthermore, managers who specialize in the management of refrigerated and frozen food distribution often can not readily determine whether the food has been distributed in a safe cold and frozen state.

Therefore, although a number of methods and apparatuses have been disclosed for determining the state of refrigeration and refrigeration during the distribution process for such food, such conventional methods and apparatuses accurately determine whether a safe refrigeration and freezing state is maintained during the whole distribution process It can not be done.

On the other hand, in order to overcome these limitations, a precise temperature time indicator (such as a time temperature indicator) (a device or label attached to the product that indicates the accumulated time-temperature record of the product) And various types of TTI have been developed and used.

However, these products have a large product size because the development material runs longitudinally on the development medium layer, and when used, it is necessary to remove the barrier layer between the development medium layer and development material layer. In addition, automation for mass production is difficult. In addition, when the developing material is exposed without being sealed, it should be cooled at a temperature below the melting point for about 1 to 2 hours before use. If the developing material is inadvertently exposed to room temperature, the developing material is melted, do. In particular, such a strip type has a disadvantage that the development rate is slowed as the developing material moves away from the starting point in one direction, and the mechanical error range for confirming the critical temperature exposure time becomes large.

In order to solve such a problem, the present inventor has filed an application for registration of the invention with the registration number 10-1123956 (name of the invention: critical temperature indicator and its manufacturing method, from the first time the frozen or refrigerated food is manufactured to the time when it is finally used A critical temperature indicator capable of mass production that can display a red warning when the storage temperature profile is monitored over time and improperly stored).

The present inventor of the present invention has been able to display the warning of red when the storage temperature of the frozen or chilled food is inadequate according to the profile of the storage temperature from the moment of the first manufacture until the last use, Since the transparent sheet and the upper sheet are precisely positioned due to the cutouts and the display windows on the material sheet, printing of a separate eye mark (assembly mark) is not required for each sheet, so that the process can be shortened and the process error can be reduced The effect is obvious.

However, the conventional critical temperature indicator is problematic in that (i) gelatin or the like surrounding the developing substance (for example, fatty acid ester) is made circular or elliptical, In case of attaching to the wrapping paper of the product when the thickness of the temperature timetable becomes thick (for example, the thickness is 5 mm to 6 mm), there is a problem that the temperature timetable period is detached during handling or transportation, and (iii) It is necessary to blow out the developing material, which also causes a problem of lowering the cost and production efficiency by adding a process to start the operation.

In order to solve the problems of the conventional critical temperature indicator, the present inventor has found that, by including a lid part made of hard plastic and ruptured when a pressure of a predetermined pressure or more is applied, Can be performed, and also has a development material unit which can be manufactured so as to have a thin thickness, thereby reducing the possibility of desorption during transportation and handling, a temperature time table including the same, and a method of activating the temperature time indicator.

The developing material accommodating portion 110 is made of hard plastic and has an empty space to accommodate a developing material 120 described later.

At this time, OPP, PET, OPS, PC and acrylic film may be used as the material of the development material accommodating portion 110, and semi-rigid plastic materials may also be used if necessary.

The developing material 120 is accommodated in the developing material accommodating portion 110 and is melted when the developing material unit 100 according to the present invention is applied at the time of the temperature time table or reaches a predetermined temperature or is out of a certain temperature range And is diffused on the developing medium medium 210 to be described later to make the developing medium medium medium 210 transparent.

The kind of the developing material 120 is not limited as long as the developing material can be melted according to the temperature and diffused on the developing medium member 210. In this case, fatty acid esters or paraffins are preferred as developing agents, and other types of developing agents can be used in various ways depending on the type and characteristics of the contents to be used in the temperature time schedule.
