Description

[Detailed description of the device] This device is used to prevent and detect unloading of pharmaceuticals, precision parts, cosmetics, etc., to prevent the replacement of defective and inferior products, and to seal sealed documents, important documents, and confidential documents. and other improvements in seals used for sealing various contents that require prevention of unauthorized tampering.

Among conventional sealing stickers, those made of paper are easily torn, and when attached to a product, are easily torn by vibrations or shocks during transportation, rendering them useless, while those made of synthetic resin are generally Although it did not break during transportation, it was difficult to break and handle when opened.

This idea was developed to eliminate the above-mentioned drawbacks of the conventional seals, and when attached to a product, it does not easily tear due to vibrations or shocks during transportation, and it can be opened easily with one's fingers. The goal is to provide an ideal seal that can be broken.

An embodiment of this invention will be described below with reference to the drawings. In the figure, 1 is a sealing base material made of a synthetic plastic film such as polyester or a semi-synthetic plastic film such as cellulose acetate. This sealing base material 1 has a slightly horizontally elongated rectangular shape, but its size and shape are It goes without saying that there are no particular limitations on the size and shape of the material, and that any size and shape can be selected depending on the purpose. Reference numeral 2 denotes a central discarded portion of the seal base material 1, and numeral 3 denotes a large number of notches arranged in opposition on both sides of the discarded portion 2. The valley portions 3a of the notches 3 are all rounded. The shape and size of this notch 3 and the valley part 3a
Although the size of the radius is not particularly determined, it may be approximately the shape of the notch 3 as shown in the drawings, or the size of the notch 3 and the radius. Although not shown in the drawings, an adhesive layer is provided on the back surface of the sealing base material 1 so that it can be pasted.

In the above embodiment, the notch 3 is attached to the sealing base material 1.
Although a large number of discarding parts 2 are arranged facing each other on both sides, there is no need to make them face each other, and there is no need to arrange such a large number of them. At least one notch 3 may be provided on one side of the discarded portion 2 of the seal base material 1.

This idea is as described above, so even if vibrations, shocks, etc. tear the center part of the product when it is pasted, the seal base material is strong because it is made of synthetic or semi-synthetic plastic film. It will not tear, and since the notch part has a rounded trough, it will not be easily torn from this part, thus preventing accidents such as the seal being torn during transportation and rendering it useless. Not only is it safe, but it is also very convenient and easy to handle, as the notch allows you to easily tear it with your fingers when opening it.

[Brief explanation of drawings]

The drawing is a plan view showing an embodiment of this invention. In the figure, 1 is a seal base material, 2 is a discarded portion, 3 is a notch, and 3a is a trough.
