JP2001356691A - Preservation state check label of thermosensitive recording paper - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a preservation state check label of thermosensitive recording paper which is capable of more surely announcing whether the thermosensitive recording paper is usable or not. SOLUTION: This label consists of a substrate which is formed with a tacky adhesive layer, a thermosensitive layer 5 which is laminated on the surface of the substrate on the side opposite to the side formed with the tacky adhesive layer and a display part 6 which is formed on this thermosensitive layer. The thermosensitive layer is held at a first display color below a quality guarantee threshold temperature and is so formed as to be held at a second display color different from the first display color when the label is exposed to the temperature above the quality guarantee threshold temperature. The printing color in the display part is made the same as the first display color and is made identifiable from the second display color. The display part is so formed that its printing 7 of the display part appears in relief when the thermosensitive recording paper is exposed to the temperature above the quality guarantee threshold temperature.

2. Description of the Related Art In general, for example, thermal recording paper such as thermal paper, thermal label, or thermal ribbon used in a thermal printer or the like, performs recording by utilizing discoloration or coloring action by heat. . By the way, in such a heat-sensitive recording paper, if the recording paper is exposed to a high temperature exceeding the quality assurance limit temperature in an unused state, the entire recording paper is discolored or deteriorated, and good color development cannot be obtained. Etc., it may be in an unusable state.

Therefore, conventionally, a heat-sensitive label that changes color when the temperature exceeds a set temperature is pasted on a package of the heat-sensitive recording paper, and the heat-sensitive recording paper can be used by confirming whether or not the heat-sensitive label has changed color. Attempts have been made to announce whether the state is unusable or unusable. As a specific example, it is conceivable to make the heat-sensitive label white when in a usable state, and to make the heat-sensitive label black when it is exposed to a high temperature, thereby notifying the use of the heat-sensitive label. Can be

[0004]

However, even in such a conventional countermeasure, the following problems to be improved remain. That is, since the heat-sensitive label is changed to black, for example, to notify an unusable state, some users do not know the meaning of the color of the heat-sensitive label or do not know whether the heat-sensitive label has changed color. However, there is a problem that the user may accidentally use it.

The present invention has been made in view of such a conventional problem, and provides a label for confirming a storage state of a thermal recording paper which can more reliably notify the user of the use of the thermal recording paper. The purpose is to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an external perspective view of a wrapped thermosensitive recording paper to which the present embodiment is applied, and the thermosensitive recording paper (illustration is omitted in the illustrated example because it is covered by a wrapping body 1 described later). Is wound in a roll shape, the surface of which is wrapped by a wrapping body 1, and the storage state confirmation labels 2 according to the present embodiment are attached to both ends of the thermosensitive recording paper of the wrapping body 1. The package 1 is sealed so as to wrap the thermal recording paper.

The storage state confirmation label 2 according to the present embodiment is attached to the thermosensitive recording paper package 2,
This is to indicate whether or not the thermosensitive recording paper has been exposed to a temperature exceeding the quality assurance limit temperature. As shown in FIG. 3, a sheet-like substrate on which an adhesive layer 3 is formed is provided. 4, a heat-sensitive layer 5 laminated on the surface of the substrate 4 opposite to the side on which the pressure-sensitive adhesive layer 3 is formed, and a display section 6 formed on the surface of the heat-sensitive layer 5. Layer 5
The first display color A is maintained at the temperature below the quality assurance limit temperature, and the second display color B changed from the first display color A when exposed to the temperature above the quality assurance limit temperature. The printing color C on the display unit 6 is the same as the first display color A, and
The second display color B is distinguishable from the second display color B. When the thermosensitive recording paper is exposed to a temperature equal to or higher than the quality assurance limit temperature, the printing on the display unit 6 is raised.

More specifically, the first display color A of the thermosensitive layer 5 below the quality assurance limit temperature is set to, for example, "blue" and is exposed to a temperature above the quality assurance limit temperature. Is set to "red", and the print color C of the display unit 6 is set to "blue".

Therefore, when the temperature is kept below the quality assurance limit temperature, the printing color C of the display section 6 of the storage state confirmation label 2 = the first display color A of the thermosensitive layer 5 = blue, and the display section 6 Is mixed with the color of the heat-sensitive layer 5,
As shown in FIG. 2, the display on the display unit 6 is deleted.

When the thermosensitive recording paper is exposed to a temperature higher than the quality assurance limit temperature, the second display color B of the thermosensitive layer 5 becomes red, but the printing color C of the display section 6 is blue. Therefore, as shown in FIG. 4, the print 7 of the display unit 6 floats on the heat-sensitive layer 5. Here, by making the print 7 a direct warning text such as "The storage temperature has exceeded the storage limit temperature, do not use it", the user can understand the warning without making a mistake, and Incorrect use of the recording paper is prevented.

On the other hand, the information described above and below the display unit 6 in FIGS. 2 and 4 is a general display such as a display indicating the size of the thermal recording paper or a display urging the user to pay attention to the storage temperature.

Next, regarding another embodiment of the present invention,
This will be described with reference to FIGS. In the following description, portions common to the above-described embodiment will be simplified by using the same reference numerals. In the storage state confirmation label 10 according to the present embodiment, the display unit 6 shown in the embodiment is divided into a first display unit 11 and a second display unit 12, and the first display unit 11 is the same color as the first display color A of the thermosensitive layer 5 and is a color that can be distinguished from the second display color B. Print color D
The second display color B of the heat-sensitive layer 5 is the same color as the second display color B and is distinguishable from the first display color A.

With such a configuration, when the thermal recording paper is not exposed to a temperature equal to or higher than the quality assurance limit temperature, as shown in FIG. When the print 13 of the first display unit 11 is hidden and is exposed to a temperature equal to or higher than the quality assurance limit temperature, as shown in FIG. The print 13 on the display unit 11 emerges, and the second display unit 1
2 is erased. This is because when the first display color in the heating layer 5 is “blue” and the second display color B is “red”, the print 13 on the first display section 11 is “blue”.
Then, the print 14 of the second display unit 12 is set to “red”.

Therefore, in the present embodiment, the print 13 on the first display unit 11 is set to “super limit temperature / unusable”, and the print 14 on the second display unit 12 is set to “good storage / By setting “usable”, it is possible to selectively notify the user of the availability in a document.

The shapes, dimensions, and the like of each component shown in each of the above-mentioned samurai history forms are examples, and can be variously changed based on design requirements and the like. For example, the first display color A and the second display color B of the thermosensitive layer 5 can be set arbitrarily. In this case, the print colors C and D on the display unit 6 are also
What is necessary is just to change according to each display color of the heat-sensitive layer 5.

[0017]

As described above, according to the label for confirming the storage state of the thermosensitive recording paper according to the present invention, a warning message can be displayed on the surface of the label due to the discoloration of the thermosensitive layer provided on the label. The user can be notified of the state of the thermal recording paper by text. Therefore, erroneous use by the user can be reliably prevented.
