Abstract

PROBLEM TO BE SOLVED: To provide a beverage can capable of opening a drinking port without embedding a cut surface of a lid into beverage. SOLUTION: This beverage can has a lid member in which a rivet hole 3 at a knob segment 6 of a ring-like knob piece having two rivet holes and a knob part is fixed by a rivet 1 at a releasing part enclosed by a cut line 5, and further another rivet hole 4 is fixed to an outer side of the releasing part by a rivet 2. With this arrangement, when the knob piece is pulled up for releasing the lid, the releasing piece forming a port is cut, the lid is pulled up together with the knob piece, resulting in that a drinking port is formed while the releasing piece at the releasing port is not immersed in the contained liquid and further the releasing piece can be turned around one rib and this is no hindrance when the contained liquid is drunk.

Description of the Related Art When drinking a conventional beverage can, the handle attached to the upper surface of the can is raised, the cut surface of the lid is pushed into the can, and the drinking spout is opened. In other words, it was necessary to drink with a part of the lid immersed in the beverage in the can. These beverage cans are produced in factories and pass through the distribution stage to consumers, during which they can be touched by human hands, and may be stained by hand, invisible dirt, dust in stocks, germs and the like. Since the upper surface of the can and the area around the attaching portion of the knob piece cannot be wiped due to the structure, attached dirt, dust, germs and the like have to be drunk with the beverage, which is extremely unsanitary and unpleasant.

The rivet hole on the knob side of the ring-shaped knob piece having two rivet holes and the knob section is riveted to the open section surrounded by the cut line, and the other is attached to the outer side of the open section. The problem can be solved by making the rivet hole a lid that is riveted. In other words, when the knob portion of the knob piece is lifted upward, the cut open portion is integrated with the knob piece and the rivet, so that it is lifted up and cut along the cutting line.
After cutting, it can be turned left or right around the fulcrum fastened by the other rivet, so turning it to either side will not be an obstacle for drinking.

Using a mold, a thin plate made of aluminum or steel is used at the outer periphery of the beverage can and has a circular recess (8) into which the cylinder of the can body can be inserted and fitted. The elliptical half-cut line (5) is formed, and a projection (1) serving as a rivet is provided inside the ellipse, and a projection (2) is provided on an extension of the projection (1) and the center of the lid outside the ellipse. Make a molded body.

The two holes of this knob piece are fitted into the two projections of the lid. At this time, the knobs are fitted so that the knobs come to the drinking side. Squash the head of the protrusion. The lid thus obtained can be fitted to and joined to a separately made body to form the beverage can of the present invention.

害にはならない。[0007] The shape of the opening portion serving as a drinking mouth formed by the score line suitable for the present invention may be a conventionally used shape. The rivet position may be easier to open in the open portion if it is located as far as possible outside the open portion. The other position is preferably located at the center or on the opposite side of the rivet position of the mouth from the center. On the other hand, the knob portion of the knob piece is one that is positioned at the tip of the rivet hole shown in FIG. 2A or that is attached to one or both sides of the hole shown in B. In A, since the knob portion protrudes outside the can, it is preferable to turn it back at the fold line (7) during manufacturing. In the case of B, the opening portion is cut along the cut line by raising the knob portion and then pulling up in use, so that the spout is opened. If you turn the rivet held on the lid after opening to the left and right around the fulcrum, it will not be an obstacle to drinking.

る。When the knob is lifted upward, the opening is cut along the half-cut line and lifted at the same time, so that the spout opens without sinking into the drinking water inside, and there is no hygiene problem. In addition, since it can be turned left and right after being lifted to open the drinking spout, the opening does not hinder the drinking of the beverage. Furthermore, since the opened opening is connected to the beverage can main body, there is an effect that it is discarded and does not become garbage.
