Description

Identification tag

Technical Field

The present invention relates to an identification tag, and more particularly to an identification tag attached to goods.

Background

Generally, in the whole process from the production completion to the transportation or storage sale site (such as supermarket) of the specific goods (such as food), the temperature of the goods needs to be kept below the predetermined temperature to prevent the goods from deteriorating.

In order to avoid the circulation of bad articles, which are not kept at a specific temperature all the time, to the market, an identification mechanism has been developed in the market, which fills an identification agent in a label on the article. In the case of frozen articles, the identifier in the label may freeze to damage the label; if the temperature is higher than the set temperature during the transportation, the refrigerator transportation, or the like, the identifier melts and leaks from the label damaged portion. Therefore, the quality control personnel can judge whether the articles are kept below a specific temperature in the whole process of carrying, refrigerator transportation and the like by the amount of the identification agent.

However, the design of the conventional label cannot ensure that the position of the label damaged by the identifier after freezing is easy for the identifier to flow out, so that the identifier is still maintained in a certain amount even if the article is at a temperature higher than a specific temperature, and a quality manager mistakenly thinks that the article meets the temperature requirement in the whole process through the unreduced identifier.

Disclosure of Invention

The invention provides an identification label, which solves the problem that the prior label design can not ensure that the position of the label damaged by an identifier after being frozen is easy to allow the identifier to flow out.

An identification tag according to an embodiment of the present invention is configured to be attached to a cargo, and includes a tag body and an identifier. The label body is used for being arranged on goods. The tag body is provided with an accommodating space, the accommodating space is provided with a first part and a second part which are connected, and the maximum depth of the first part is greater than that of the second part. The identification agent is stored in the accommodating space and can change between two different states. When the identification agent is changed from one state to the other state, the volume of the identification agent is increased, so that the label body is provided with at least one fracture opening communicated with the containing space. The rupture port is located in the first portion.

In another embodiment of the present invention, an identification tag for being mounted on goods includes a tag body and an identification agent. The label body is used for being arranged on goods. The tag body is provided with an accommodating space, and the accommodating space is provided with a first part, a second part and a plurality of corners. The first portion is connected with the second portion, the corners are respectively located on the first portion and the second portion, and the number of the corners located on the first portion is smaller than that of the corners located on the second portion. The identification agent is stored in the accommodating space and can change between two different states. When the identification agent is changed from one state to the other state, the volume of the identification agent is increased, so that the label body is provided with at least one fracture opening communicated with the containing space. The rupture port is located in the first portion.

Another embodiment of the present invention discloses an identification tag for being mounted on goods, which includes a tag body and an identifier. The label body is used for being arranged on goods. The tag body is provided with an accommodating space and a plurality of protruding structures, the accommodating space is provided with a first part and a second part, the first part is connected with the second part, and the protruding structures are located on the second part. The identification agent is stored in the accommodating space and can change between two different states. When the identification agent is changed from one state to the other state, the volume of the identification agent is increased, so that the label body is provided with at least one fracture opening communicated with the containing space. The rupture port is located in the first portion.

According to the identification tag disclosed in the above embodiment, by the maximum depth of the first portion of the accommodating space being greater than the maximum depth of the second portion, the number of the corners of the accommodating space located in the first portion being less than the number of the corners located in the second portion, or the protruding structures being located in the second portion of the accommodating space, when the identification tag is at the second temperature less than the freezing point of the identification agent, the identification agent is frozen from the second portion of the accommodating space first, and then is frozen toward the first portion of the accommodating space of the tag body, so that the stress generated by the frozen expansion of the identification agent is finally concentrated in the first portion of the accommodating space, and a crack is generated in the first portion of the accommodating space. Therefore, if the goods provided with the identification label is at the first temperature higher than the freezing point of the identification agent, the identification agent melted into the liquid can be ensured to flow out from the fracture opening by gravity, so that the quality control personnel can judge the bad goods.

Detailed Description

Next, referring to fig. 1 and fig. 2, fig. 1 is a schematic perspective view of an identification tag according to a first embodiment of the present invention. Fig. 2 is a schematic cross-sectional view of the identification tag of fig. 1.

In the present embodiment, the identification tag 1a is used to be attached to goods. The goods are, for example, foodstuffs which are to be preserved, for example, by freezing or refrigeration. The identification tag 1a includes a tag body 10a and an identifier 20 a. In addition, in this embodiment or other embodiments, the identification tag 1a may further include an identification member 30 a.

The label body 10a includes a substrate 11a and a film 12a, and the film 12a is disposed on the substrate 11a by bonding or hot pressing. The tag body 10a is disposed on the goods. The label body 10a can be disposed on the goods through the base material 11a or the film 12 a. The membrane 12a and the substrate 11a together form an accommodating space 14 a. The shape of the accommodating space 14a is, for example, but not limited to, similar to a rectangle. The accommodating space 14a is divided into a first portion 141a and a second portion 142a connected to each other via a reference surface S1. As shown in fig. 2, a portion of the accommodating space 14a located below the reference plane S1 is a first portion 141a, and a portion of the accommodating space 14a located above the reference plane S1 is a second portion 142 a.

The maximum depth of the first portion 141a of the accommodating space 14a is greater than the maximum depth of the second portion 142 a. The first portion 141a of the accommodating space 14a having the maximum depth is located on a side of the first portion 141a away from the second portion 142a, and the second portion 142a of the accommodating space 14a having the maximum depth is located at a junction of the first portion 141a and the second portion 142 a. In fact, the depth of the accommodating space 14a increases from the side of the second portion 142a away from the first portion 141a toward the first portion 141 a. As shown in fig. 2, the minimum depth D1 of the accommodating space 14a is greater than 0, but not limited thereto. In other embodiments, the minimum depth of the accommodating space may be equal to 0.

The identifier 30a is, for example, a letter printed layer which displays a slogan in which the goods have a flaw, such as a goods abnormality. The identification piece 30a is disposed in the accommodating space 14a of the tag body 10 a. In detail, the identifier 30a is disposed at the bottom of the accommodating space 14a and is located on a surface of the substrate 10a facing the accommodating space 14 a.

The identifier 20a is stored in the housing space 14a of the tag body 10 a. The identifier 20a includes, for example, water and a dye, and the dye is mixed in the water, so that the identifier 20a has a color. In the present embodiment, the base material 11a and the film 12a of the label body 10a are transparent, for example, so that the identifier 20a in the accommodating space 14a of the label body 10a can be seen by naked eyes. In this case, the identifier 20a shields the identifier 30 a. In addition, the identifier 20a may vary between a liquid state and a solid state, and the freezing point of the identifier 20a is, for example, 0 degree celsius.

As shown in fig. 2, when the identification tag 1a is at a first temperature greater than the freezing point of the identification agent 20a, the identification agent 20a is in a liquid state and is filled in the accommodating space 14a of the tag body 10 a.

In the present embodiment, the tag body 10a has a to-be-destroyed region G1, and the to-be-destroyed region G1 is located at the bottom of the tag body 10 a. In detail, the intended breakage region G1 is located on a side of the first portion 141a away from the second portion 142 a. The to-be-destroyed region G1 is where the identifier 20a expands to destroy the tag body 10a at a second temperature below the freezing point of the identifier 20 a.

Next, referring to fig. 3, fig. 3 is a schematic cross-sectional view of the identification tag at the second temperature in fig. 2. The goods are maintained at a second temperature below the freezing point of the identifier 20a prior to storage or shipment to the point of sale, whether by handling or shipment. That is, the freezing point of the identifier 20a is the temperature required to preserve the cargo. When the identification tag 1a is attached to the goods and the two are frozen (stored) together in the environment of the second temperature, the depth of the accommodating space 14a is gradually increased from the side of the second portion 142a away from the first portion 141a toward the first portion 141a, so that the identifier 20a can be frozen first in the second portion 142a of the accommodating space 14a and then gradually frozen toward the first portion 141a of the accommodating space 14 a. Since the volume of the frozen solid identifier 20a increases, the stress applied to the tag body 10a by the process of freezing the identifier 20a toward the first portion 141a of the accommodating space 14a is finally concentrated in the region to be destroyed G1, and the tag body 10a is ruptured, so that the region to be destroyed G1 of the tag body 10a forms at least one rupture opening 15a in the first portion 141a of the accommodating space 14 a. At this time, since the identifier 20a is solidified into a solid, the identifier 20a does not leak from the fracture 15 a. The size of the rupture 15a shown in the drawings is merely an example and is not intended to limit the present invention.

Next, referring to fig. 4, fig. 4 is a schematic cross-sectional view of the identification tag of fig. 3 once at an improper temperature. If the goods to which the identification label 1a is attached is in an environment having a temperature higher than the freezing point of the identification agent 20a during transportation or transportation, the identification agent 20a in the identification label 1a melts into a liquid, and leaks out of the rupture 15a by gravity, thereby exposing the identification member 30 a. In this way, after the identifier 20a is leaked, the keeper can confirm that the goods is at an inappropriate temperature (e.g., the first temperature) by showing the back of the identifier tag 1a, the change in the amount of the identifier 20a, and/or the appearance of the identifier 30a through the appearance of the identifier tag, so that it is possible to prevent the defective goods that are not kept below the freezing point of the identifier 20a all the way from being distributed to the market.

In addition, the depth of the accommodating space 14a is not limited to increase from the side of the second portion 142a away from the first portion 141a toward the first portion 141 a. For example, referring to fig. 5, fig. 5 is a schematic cross-sectional view of an identification tag according to a second embodiment of the disclosure.

In the embodiments described above, the freezing point of the identifier is not limited to 0 degrees celsius. In other embodiments, the freezing point of the identifier can be adjusted depending on the temperature required to preserve the cargo. For example, if the temperature required for storing the goods is lower or higher, such as less than or greater than 0 ℃, the identifier may further comprise salt, vinegar, methanol, ethanol, ethylene glycol, glycerol, and the like, so as to increase or decrease the freezing point of the identifier.

In the embodiments, the region to be damaged is not limited to be located at the bottom of the tag body. In other embodiments, the area to be damaged may be located at any position of the membrane adjacent to the edge of the first portion of the accommodating space of the tag body, and the fracture opening formed by the identifier which is solidified to damage the tag body may also be located at any position of the edge of the first portion of the accommodating space.

According to the identification tag disclosed in the above embodiment, by the maximum depth of the first portion of the accommodating space being greater than the maximum depth of the second portion, the number of the corners of the accommodating space located in the first portion being less than the number of the corners located in the second portion, or the protruding structures being located in the second portion of the accommodating space, when the identification tag is at the second temperature less than the freezing point of the identification agent, the identification agent is frozen from the second portion of the accommodating space first, and then the identification agent is frozen toward the first portion of the accommodating space of the tag body, so that the stress generated by the frozen expansion of the identification agent is finally concentrated in the first portion of the accommodating space, and a crack is generated in the first portion of the accommodating space. Therefore, if the goods provided with the identification label is at the first temperature higher than the freezing point of the identification agent, the identification agent melted into the liquid can be ensured to flow out from the fracture opening by gravity, so that the quality control personnel can judge the bad goods.

It should be noted that the present invention does not limit the kind of the identifier; in other embodiments, the identifier may comprise carbon dioxide, and the identifier undergoes a phase change between a solid and a gas. Specifically, when the identifier stored in the tag body is at 1 atmosphere and the temperature is lower than-78.5 ℃, the identifier is in a solid state; when the identifier stored in the tag body is at 1 atmosphere and the temperature is higher than-78.5 degrees centigrade, the identifier changes from solid to gas, and the volume of the identifier increases to cause the tag body to generate a crack. Thus, the identification tag may be used with products that require storage at temperatures below-78.5 degrees celsius. Thus, a worker can intuitively determine that the product is not stored at the desired temperature by identifying the appearance of the label (e.g., the presence of a rupture).

On the other hand, in the present invention, the rupture port on the label body may be generated by a phase change between liquid and gas of the identifier. For example, the identifier may be nitrogen. When the identifier stored in the label body is at 1 atmospheric pressure and the temperature is lower than-196 ℃, the identifier is in a liquid state; when the identifier stored in the tag body is at 1 atmosphere and a temperature higher than-196 degrees celsius, the identifier changes from a liquid state to a gas state, and the increase in volume of the identifier causes a rupture in the tag body. Thus, the identification tag may be used with products that need to be stored at temperatures below-196 ℃.
