Description of the Invention: [Technical Field of the Invention] The present invention relates to a sealing sticker for attaching to a can end of a can container to achieve a closed function. [Prior Art] Tank containers are usually used to hold processed foods, especially dried products, and in order to ensure good airtightness of the cans of such containers, in the past, aluminoplatin was used by means of hot melt. Fit and close; however, this method needs to be carried out with large size and precision, and aluminum-platinum is not suitable for printing. Therefore, there is a modified design such as the sealing sticker 5 shown in Fig. 4, which is a sticker as shown in Fig. 5. One of the surfaces is coated with an adhesive layer 5 i, and a release paper 52 is attached to the adhesive layer 5 1 in a manner that the sticker is attached to the release paper and then the sticker is cut into a similar shape. The crepe sheet 50 is placed on the inner bottom surface of the can lid to be attached to the can, and the release paper is cut to be similar to the sheet 502 under the can size of the can to be attached, so that the adhesive is peeled off when the upper sheet 501 is peeled off. A relatively small lower sheet 502 is attached to the layer, and the adhesive layer 51 of the upper sheet is only annularly exposed on the edge thereof. The sealed sticker of this design is used without any other equipment, but by hand. The way is placed on the inner bottom surface of the can lid 6 1 as shown in Fig. 6, and the can lid is combined to the can In the case of the mouth of the child 6, the adhesive layer of the sticker is adhered to the end surface of the can of the secondary can. However, the mouth is occasionally cut off due to the occasional cutting of the release paper, and the use is exceptional/ In addition, when peeling off a piece of sealing sticker from the sticker, if the lower sheet is not completely cut, only the upper sheet will be peeled off, which is not suitable for sealing the can. 1274016 In view of these problems, it is indeed necessary to improve them and present the present invention. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide a sealing sticker mainly designed as a single piece, which can avoid the problem of cutting and tearing, and can be peeled off at the same time without peeling off the sealing paper when peeling off the sealing sticker. . In order to achieve the above object, the present invention provides a sealing sticker which is formed into a predetermined shape and defines two opposite upper surfaces and a lower surface, and an adhesive layer is completely evenly distributed on the lower surface, and the surface of the adhesive layer is not A printed layer is completely covered, and a distance is maintained along the edge of the printed layer from the edge of the sealing sticker to form an annular adhesive layer within the spacing. The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments of the invention. The present invention may be different in some steps, or in the arrangement of steps, but the selected embodiments are described in detail in the present specification and are shown in the accompanying drawings. [Embodiment] Referring to Figures 1 and 2, the structure shown in the drawings is the structure of the embodiment selected for the present invention. This is for illustrative purposes only, and is not limited by such structure in the patent application. The area and shape of the sealing sticker 1 depends on the inner bottom edge of the can lid which is matched with the can to be attached, and defines two opposite upper surface surfaces i and a lower surface 12, which are completely evenly distributed on the lower surface. Adhesive layer i 3, another 1274016 The surface of the adhesive layer is not completely covered with an area and shape depending on the edge of the can to be attached and the edge of the sealing sticker 10 to maintain the layer. The printed layer 14, the towel, the inner edge of the printed layer, and the spacing between the sides of the printing layer, the shape of the gap is formed into a small %-shaped adhesive lower surface 12, and the lower surface of the sheet is completely evenly distributed. The foregoing sealing sticker has a sheet 1 as compared with (a). The sheeting method is as follows. Referring to Fig. 3, there are two opposite upper surfaces 11 and an adhesive layer 1 continuously printed with a plurality of gauges 4. The adhesive layer and the printed layer on the lower surface (b) the printed layer of the predetermined area and shape of the adhesive layer 13 of the sheet 1 (c) is attached to the sheet by a release film 2 (d) The cutting blade 3 is cut into a predetermined shape by a predetermined distance around the respective printing layers to form a predetermined shape of the sealing sticker 10 and the annular adhesive layer is retained. i. The sealing sticker obtained by the above invention can be used to directly cover the printing layer. Adhesive layer, so only the annular adhesive layer on the periphery of the printed layer has adhesiveness, so that the inner side of the can lid can be directly put into the hand by hand, and when the can lid is combined to the can end of the can, the sealing sticker The adhesive layer is adhered to the end face of the can of the secondary can. The invention is characterized in that, when the strip is peeled off from the sheet, the peeling film is separated from the peeling film below, and becomes a single-layer design sticker, and the printing layer can replace the conventional lower sheet, so the cutting and sealing sticker is relatively free. The problem of being cut by the cutter, and if the cutting is not complete, it can be torn open.
