That is, the yield of the lid label 100 when the package 10 is manufactured can be improved. Specifically, when manufacturing the packaging body 10 including the lid label 100 of the present embodiment, the number of the lid labels 100 used is reduced with respect to the number of the packaging body 10 produced, and the yield is 90% or more. be able to.

  Next, experimental results serving as examples for demonstrating the effects of the embodiment of the present invention described above will be described. In this example, an evaluation experiment for confirming the sealing property at the time of use by using the lid label of the wet sheet packaging according to the embodiment of the present invention was performed. In addition, this invention is not limited to a present Example.

  As an example, a thick label (thickness: 200 μm), which is a lid label for a wet sheet packaging body according to an embodiment of the present invention, was prepared. In addition, as Comparative Example 1 to be compared with such an Example, an outer frame non-label having a conventional thickness (100 μm) of the same shape as the thick label of the Example is prepared. A label with an outer frame of Japanese Unexamined Patent Publication No. 63-152577 having a conventional thickness (100 μm) of the same shape as the thick label of the example was prepared. And the volatility at the time of use in each label was confirmed.

Specifically, the evaluation method according to the following procedure was performed.
Forty sheets (wet tissue) were packed with a package made of a composite sheet structure in which the bag body was bonded with aluminum foil and a synthetic resin sheet. A sample of a wet sheet packaging in which each label of Example 2 was pasted as a lid label was prepared.
The process of closing the label every time one sample sheet of each wet sheet packaging is extracted is repeated 10 times (10 sheets), 20 times (20 sheets), and 30 times (30 sheets). It was.
After the above extraction process, the weight of the sample product immediately after that and the weight of the sample product after standing for 4 days at room temperature are measured, and the loss on drying (weight loss) is measured from the difference between these weights. ((Loss on drying / product weight after extraction) × 100) was calculated.
In this evaluation test, the above steps 2) and 3) were each performed three times, and measured, calculated three times, and the calculated product weight after sampling, the product weight after standing for 4 days, the weight loss, and the drying weight loss rate. The average value was obtained.

Table 1 shows a summary of the verification results of volatility during use according to the above-described evaluation method for each label according to the example, comparative example 1, and comparative example 2 described above.

  From Table 1, the thick label of the example which is the label for the lid of the wet sheet packaging according to the embodiment of the present invention is repeatedly used as compared with the other labels of Comparative Example 1 and Comparative Example 2. It was found that the loss on drying rate was small. In particular, as the number of extracted sheets increases to 20 and 30, the thick label which is the lid label according to the example has a drastic improvement in the weight loss on drying compared to the labels of Comparative Example 1 and Comparative Example 2. I understood. That is, the thick label of the present embodiment is attached without any gap when the thick label is attached to the bag body 12 again in order to close the outlet 14, so that the label of the thick label is different from those of other comparative examples. It was proved that the hermeticity of the package 10 can be secured even when the attachment and detachment is repeated.

  Although one embodiment and each example of the present invention have been described in detail as described above, it will be understood by those skilled in the art that many modifications that do not substantially depart from the novel matters and effects of the present invention are possible. It will be easy to understand. Therefore, all such modifications are included in the scope of the present invention.

  For example, a term described with a different term having a broader meaning or the same meaning at least once in the specification or the drawings can be replaced with the different term in any part of the specification or the drawings. Further, the configurations and operations of the wet sheet packaging body and the lid label are not limited to those described in the embodiment and the examples of the present invention, and various modifications can be made.
