JPH08411U - Improvement of drinking mouth of aluminum beverage can - Google Patents

Abstract

(57) [Summary] [Purpose] The mouth of an aluminum beverage can of juice or beer is uncomfortable when you try to drink it because the joint between the top lid and the container is protruding outside. Round the mouth to make the liquid easier to drink. [Structure] Remove the joint between the top lid and the container and add a rounded shape. The one in which the bottom of the can and the container are integrally molded has been around in the market, but by applying this, the upper lid and the container are integrally molded. By rounding the rim of the can at that time, the taste when drinking is improved. You can enjoy the subtle taste of the contents without dust collecting on the top lid.

Description

[Detailed description of the device] The joint between the upper lid and the container at the mouth of the aluminum beverage can protrudes upward, so there is some resistance when drinking. If you lower the joint a little and make the edges round as shown in the upper lid 4 in the figure, the taste will be softer when you drink. It also eliminates the fact that dust that has been left outside for a long time has stuck between the edges, making it difficult to wash even after washing with water. As the mouth feels better, the drinking water in the drink will be more delicious and you can enjoy the mellow taste. Fig. 1 shows the joint between the top lid and the container. The upper right circle is an enlargement of it.

 Fig. 2 is a diagram in which the mouthpiece on the top lid is cut to the edge and lengthened. If you leave the notch at the end, the metal fitting will be stuck in the upper lid and will not separate when pulled.

 Figure 3 shows a hook-shaped joint 1 to increase tensile strength. An enlarged view is in the upper right circle.

 Figure 4 is a design that presses the can upside down. A height adjusting device 12 is installed between the conventional press outside machine 11 and the press inside machine 10 to function as a stopper.

 Fig. 5 shows the case where the drinking spout is attached to the bottom of the aluminum can with the lid joined at one place. In this method, the plate thickness of the aluminum container is the same as the lid, or the container outer shape is thick only at the bottom. It is an application that rounds the drinking mouth, but you can also use the outer shape with the bottom part flat and the joint part 1 in Figure 1 removed.

 Fig. 6 shows that when making a mouthpiece on a curved surface such as the bottom, the cutting blade 15 is pressed to match the curved surface.

 FIG. 7 is a press drawing when a round mouth-contacting surface is attached to the drinking mouth of the upper lid 4. When the convex portion of the molding die 19 pushes up the aluminum lid 4, a press along the shape 18 of the curved surface of the lid attached to the die concave portion 17 can be performed. The recessed part of 19 is provided to allow the bending of the joint to escape when pressing.

 Fig. 8 is a plan view of Fig. 7 lid press. The finish of the press surface is better when the lid 3 is removed from the lid.

 We have devised an aluminum beverage can as an example, but if the edge of the top lid is rounded, it will feel better and can also be used for general containers such as cans. Also, if you make a hole in the rounded edge, it will be easier for water to come out by tilting the can a little, and it can be used in such areas because it drains well.

Claims (1)

[Scope of utility model registration request] The joints of the upper lid at the mouth of aluminum beverage cans are eliminated to soften the mouth feel, and the notch of the beverage can that is difficult to drink is fixed by extending the notch of the mouth to the full edge.
