手数を要する。PRIOR TECHNOLOGY Cans with an opening part are often used for cans filled with beverages in order to open the can without the need for tools such as a can opener. Usually, it is torn off to one side via a tear-off piece that is superimposed and fixed on one end. In this case, if the unsealing part is formed to be considerably wider than the tear-off piece, the tear-off piece will peel off from its attached part before the stamped strip is torn off because a large force is required to peel it off. There is a risk. For this reason, for items that require opening over a wide area over the entire surface of the top plate, such as general canned food, the opening section is formed in a spiral shape and is torn off sequentially using a tear-off piece fixed to one end. is used. However, since this product is opened in a long and narrow strip, it is time-consuming to open the package, and leaving the cut piece on the top plate becomes a hindrance to removing the contents. Many of the packages are cut off, and it takes a lot of effort to dispose of the scattered pieces.

できるようにしたものである。Means to Solve the Problems This invention solves the drawbacks of the conventional product by allowing the entire surface of the top plate to be opened wide and the contents to be taken out while leaving the opening part connected to the peel-off piece on the top plate. This is how it was done.

The peripheral edge is integrally connected to the side plate 8 by seaming. On the top surface of this top plate 1, there is a line passing through the center of the top plate (X-
Indicated by X. ) is the front-rear direction (the left side of Figure 1 is the front, the right side is the rear), and symmetrically about this line, with the front and rear ends located between the top plate periphery and the top plate center, and the arrow A raised surface 2 of the shape, an engraved strip 3 that surrounds the top plate 1 with a part of the rear edge remaining near the periphery of the top plate, and a raised surface 2 that also surrounds the center of the top plate and has both tips. Each U-shaped stamping strip 4 is provided,
Further, the peel-off piece 5 is superimposed on the top plate 1, and its tip is crimped with a stud 6 at the center of the top plate, and the peel-off piece 5 is superposed on the top plate 1.
At the rear end of this tear-off piece 5, there is a ring-shaped handle portion 7.
form. As shown in the sectional view of FIG. 3, the specific structure of the stud 6 is such that the center portion of the top plate 1 is projected, a peel-off piece 5 is fitted into it, and the stud 6 is formed by caulking.

は全開される。Function This device has the above-mentioned structure. To open the package, first press the raised surface 2 with your fingertips, and the surface 2 will have a raised edge. Therefore, a portion 3' of the stamped strip 3 near the tip of the surface 2 is broken, resulting in the state shown in FIG. 2A. Next, the tear-off piece 5 is pulled upward via the handle 7 to break the U-shaped stamped strip 4 as shown in FIG. 2B. Subsequently, when the tear-off piece 5 is pulled backward (to the right in FIG. 1), the partially broken portion 3' of the stamped strip 3 is expanded, and the stamped strip 3 is broken over its entire length. The unsealing section is fully opened as shown in Figure 2C.

めて容易としたものである。 As described above, this device sequentially arranges the symmetrical embossed strips 3, the raised surface 2, the embossed shapes 4, and the tear-off pieces 5 on the same line, and the raised surface 2
After making a cut in the stamped strip 3 along the circumference of the top plate 1 in advance by rolling down the U-shaped stamped strip 4, the U-shaped stamped strip 4 is broken through the tear-off piece 5, and the rising point by the tear-off piece 5 is cut as much as possible. By moving it forward, the lifting force is effectively utilized, and the remaining part of the stamped strip 3 can be broken extremely easily.
