Description

timing label

The new model relates to a timing label, in particular to a timing label for judging time by means of the diffusion of reagents.

Generally speaking, at present, during the entire process of transporting certain items (such as food or medicine) to storage or sales locations after production, it is necessary to keep the ambient temperature of the items below a predetermined temperature to ensure the quality of the items.

At present, an identification label has been developed on the market, which can help personnel to determine whether the item is kept under a specific temperature environment during the process of handling and refrigerated transportation. However, not all items cannot be used once they are in an environment of inappropriate temperature. Some items can still be used if the time in an environment of inappropriate temperature is within the allowable range. Therefore, the quality of the items can still be ensured by immediate detection and disposal by personnel. However, at present, the identification tag can only determine whether the item is kept under a specific temperature environment throughout the whole process, and cannot determine the time when the item is in an environment with an inappropriate temperature, so that the personnel still cannot judge whether the item is still a good product.

The present invention provides a timing label, which can help a person to identify the time when an item is in an environment with an inappropriate temperature.

A timing label disclosed in an embodiment of the present invention includes a base layer, a reagent layer, a separation layer, a diffusion layer and a surface layer. The reagent layer is arranged on the base layer, and the reagent layer includes a reagent, and the reagent can be phase-changed between solid state and liquid state. The spacer layer is at least partially removably disposed on the base layer and covers the reagent layer. The diffusion layer is located on the side of the separation layer away from the base layer, and at least part of the separation layer is located between the diffusion layer and the reagent layer. The surface layer covers the diffusion layer and the separation layer. After at least a portion of the spacer layer is removed, the diffusion layer absorbs the reagent that has changed from solid state to liquid state to allow the reagent to diffuse through the diffusion layer.

According to the timing label disclosed in the above-mentioned embodiment, after at least part of the separation layer is removed, when the reagent changes from solid state to liquid state due to the increase of the ambient temperature, the reagent can be absorbed by the diffusion layer and diffused in the diffusion layer, so Personnel can know the time when the item measured by the timing label is at an improper ambient temperature through the length of the diffusion of the reagent in the diffusion layer. for good.

The separation layer 30 includes a fixing portion 31 and an operating portion 32 . The operating portion 32 is removably connected to the fixing portion 31 through, for example, a one-point disconnection 33 . One surface of the fixing portion 31 is fixed on the surface of the base film 11 facing away from the release film 13 , for example, by means of adhesion, and the operation portion 32 covers the reagent layer 20 , so that the reagent layer 20 is located between the operation portion 32 and the base film 11 . and the operating portion 32 protrudes from an edge 14 of the overall base layer 10 .

The diffusion layer 40 is located on the side of the separation layer 30 away from the base layer 10 , and at least part of the separation layer 30 is located between the diffusion layer 40 and the reagent layer 20 . The surface layer 50 covers the fixed part 31 of the diffusion layer 40 and the spacer layer 30 and part of the operation part 32 . The detailed structures of the diffusion layer 40 and the surface layer 50 and the stacking relationship among the surface layer 50 , the diffusion layer 40 and the separation layer 30 will be described in detail below.

Specifically, the surface layer 50 includes a light-transmitting film 51 and an ink layer 52 . The light-transmitting film 51 is, for example, a plastic film, and its material is, for example, polypropylene (PP), polyethylene (PE), and polyethylene terephthalate (PET). The ink layer 52 is provided on the light-transmitting film 51 by, for example, printing. The ink layer 52 has two hollow parts 521 and 522 separated from each other.

The diffusion layer 40 includes porous absorbing materials, resins and other substances (such as titanium dioxide, barium oxide, toner, etc.), wherein the porous absorbing materials are, for example, diatomaceous earth, kaolin, cellulose, silica, zeolite sand, white mud sand and other substances. The diffusion layer 40 is disposed on the ink layer 52 by, for example, printing, and has a portion stacked on the surface of the ink layer 52 opposite to the light-transmitting film 51 and a portion located in the two hollow parts 521 and 522 of the ink layer 52, so that the two hollow parts are hollowed out. The portions 521 and 522 expose different portions of the diffusion layer 40, respectively. The diffusion layer 40 has a first end portion 41 , a second end portion 42 and a middle portion 43 , the first end portion 41 is opposite to the second end portion 42 , and the middle portion 43 is located at the first end portion 41 and the second end portion 43 between sections 42. The hollow portion 521 exposes a portion of the first end portion 41 of the diffusion layer 40 , and the hollow portion 522 exposes a portion of the middle portion 43 and a portion of the second end portion 42 of the diffusion layer 40 , but not limited thereto. In other embodiments, the hollow portion 521 may expose the entire first end portion 41 , and the hollow portion 522 may expose the entire second end portion 42 . In addition, the ink layer 52 is not limited to have two hollow parts 521 and 522 . In other embodiments, the ink layer may have only one hollow portion, and the hollow portion exposes the entire diffusion layer.

In this embodiment, the ink layer 52 also has a plurality of marks 523 . These marks 523 are, for example, numerals 2 and 4, respectively. The two numbers represent the time for the reagent 22 to diffuse to the position corresponding to the two numbers in the diffusion layer 40 , and the unit of time is, for example, hours. These marks 523 correspond to different positions of the hollow portion 522 respectively, and are separated from the hollow portion 521 by different distances. The purpose of these marks 523 will be described in detail later.

The fixing portion 31 of the separation layer 30 is disposed on the ink layer 52 on the surface opposite to the base film 11 , for example, by means of adhesion, so that the fixing portion 31 is fixed between the base film 11 and the second end portion 42 and the middle portion 43 of the diffusion layer 40 . , and part of the operating portion 32 is located between the first end portion 41 of the diffusion layer 40 and the reagent layer 20 , and the operating portion 32 protrudes from an edge 53 of the overall surface layer 50 .

In this embodiment, the timing tag 1 can measure the time of the article at an inappropriate ambient temperature. Please refer to FIG. 5 . FIG. 5 is a schematic top view of the separation layer of FIG. 4 after the operation portion is removed. First of all, the first end of the diffusion layer 40 can be removed by applying force to the operation part 32 of the separation layer 30 by fingers, so that the operation part 32 is separated from the fixing part 31 (as shown in FIG. 2 ) along the point-breaking line 33 and removed. The portion 41 comes into contact with the reagent layer 20 .

Next, please refer to FIG. 6 . FIG. 6 is a schematic top view of FIG. 5 showing the diffusion of the reagent in the diffusion layer. When the ambient temperature of the article increases to an inappropriate temperature, the reagent 22 in the reagent layer 20 will change from a solid state to a liquid state, so that the reagent 22 is absorbed by the first end 41 of the diffusion layer 40 , and the reagent 22 is absorbed by the diffusion layer 40 start to spread. Since the reagent 22 has dyes, the personnel can easily see the diffusion of the reagent 22 in the diffusion layer 40 from the appearance of the timing label 1 . For example, as shown in FIG. 6 , if a person observes that the reagent 22 has diffused to the position corresponding to the number 2 when the reagent 22 has been diffused in the diffusion layer 40 , it means that the article is at an inappropriate ambient temperature for about 2 Hours. In this way, the personnel can know the time when the item is at an inappropriate ambient temperature, which can be used as a basis for judging whether the item is still a good product.

In the present embodiment, the diffusion rate of the reagent 22 in the diffusion layer 40 can be adjusted according to requirements, and the adjustment method can be, for example, by adjusting the contents of various substances in the diffusion layer 40, as shown in the following table. diffusion layer Porous Absorbent Material resin other substances Diffusion time (cm/hour) Recipe 1 80 20 0 13.5 Recipe 2 70 20 10 10 Recipe 3 60 20 20 9 Recipe 4 50 20 30 4.6 Recipe 5 40 20 40 0.9 Recipe 6 20 20 60 0.1 Other substances: titanium dioxide, barium oxide, metal oxides and toners, etc.

As can be seen from the above table, the higher the content of porous absorbing material in the diffusion layer 40 and the lower the content of resin and other substances, the faster the diffusion rate of the reagent 22 in the diffusion layer 40 . Conversely, the smaller the content of the porous absorbing material in the diffusion layer 40 and the higher the content of resin and other substances, the slower the diffusion speed of the reagent 22 in the diffusion layer 40 . That is to say, the diffusion rate of the reagent 22 in the diffusion layer 40 is positively correlated with the content of the porous absorbing material in the diffusion layer 40, and is negatively correlated with the content of the resin and other substances.

In this embodiment, the ink layer 52 of the surface layer 50 is provided with the marking 523, which is not intended to limit the present invention. In other embodiments, the ink layer on the surface layer may not have markings, and the personnel can measure the length of the reagent to change the color of the diffusion layer with a ruler, and divide the length by the known diffusion speed of the reagent in the diffusion layer to know that the article is in an inappropriate condition. time at ambient temperature.

In addition, the arrangement that the reagent 22 contains a dye is not intended to limit the present invention. In other embodiments, the reagents may not contain dyes, and a person may know that the article is in an inappropriate condition by measuring the length of the reagent-wetted diffusion layer and dividing the length by the known diffusion rate of the reagent through the diffusion layer. time at ambient temperature.

On the other hand, only the operation part 32 of the separation layer 30 is removable is not intended to limit the present invention. In other embodiments, the spacer layer may be provided with an entire layer removable. Furthermore, the arrangement that the separation layer 30 includes both the fixing portion 31 and the operating portion 32 is not intended to limit the present invention. In other embodiments, the spacer layer may have no fixing portion.

In addition to adjusting the content of the substance in the diffusion layer 40 to adjust the diffusion speed of the reagent 22 in the diffusion layer 40, the diffusion speed of the reagent 22 in the diffusion layer 40 can also be adjusted by other methods. In detail, please refer to FIG. 7 , which is a schematic plan view of the diffusion layer disclosed according to the second embodiment of the present invention.

In this embodiment, the diffusion layer 40a also has a plurality of hydrophobic patterns 44a. These hydrophobic patterns 44a are made of, for example, polyvinyl fluoride or the like. The hydrophobic patterns 44a are located at the first end portion 41a and extend toward the second end portion 42a, and the widths of the respective hydrophobic patterns 44a gradually decrease toward the second end portion 42a. Therefore, the hydrophobic patterns 44a can help the reagent to diffuse from the first end portion 41a to the second end portion 42a in a concentrated manner, thereby effectively increasing the diffusion speed of the reagent in the diffusion layer 40a.

On the other hand, the diffusion speed of the reagent in the diffusion layer 40a can be adjusted by increasing or decreasing the number of the hydrophobic patterns 44a. In detail, the larger the number of the hydrophobic patterns 44a, the faster the diffusion rate of the reagent in the diffusion layer 40a. Conversely, the smaller the number of the hydrophobic patterns 44a, the less the increase of these hydrophobic patterns 44a to the diffusion rate of the reagent in the diffusion layer 40a.

Next, please refer to FIG. 8 , which is a schematic plan view of the diffusion layer disclosed according to the third embodiment of the present invention.

In this embodiment, the width W2 of the middle portion 43b and the second end portion 42b of the diffusion layer 40b is smaller than the width W1 of the first end portion 41b except that the first end portion 41b of the diffusion layer 40b has the hydrophobic pattern 44b. In this way, the reagent can be concentratedly diffused from the first end portion 41b to the second end portion 42b, and the diffusion speed of the reagent in the diffusion layer 40b can be effectively increased.

However, in other embodiments, the width of the middle portion and the second end portion of the diffusion layer can be adjusted to be larger than the width of the first end portion, so as to slow down the diffusion rate of the reagent in the diffusion layer. It can be seen that the width of the diffusion layer is negatively correlated with the diffusion rate of the reagent in the diffusion layer.

On the other hand, the provision of the hydrophobic pattern 44b on the first end portion 41b is not intended to limit the present invention. In other embodiments, the first end may not have a hydrophobic pattern.

According to the timing label disclosed in the above-mentioned embodiment, after at least part of the separation layer is removed, when the reagent changes from solid state to liquid state due to the increase of the ambient temperature, the reagent can be absorbed by the diffusion layer and diffused in the diffusion layer, so Personnel can know the time when the item measured by the timing label is at an improper ambient temperature through the length of the diffusion of the reagent in the diffusion layer. for good.

Although the present invention is disclosed by the above-mentioned preferred embodiments, it is not intended to limit the present invention. Anyone who is familiar with the similar arts can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of patent protection for a new model shall be determined by the scope of the patent application attached to this specification.
