The present invention relates to a method for manufacturing a beverage can opener, and more particularly, to a beverage can opener manufacturing method that anyone can easily open a beverage can by removing the beverage can opener at the same time when the sticker attached to the beverage can lid is removed. will be.

In general, there is a beverage can made of a metal material among the beverage containers used to distribute and market various beverages such as carbonated beverages, ionic beverages and alcoholic beverages stored therein.

Beverage cans made of metal are largely classified into aluminum cans and steel cans according to their materials, and steel cans have a plating layer for preventing rust.

Beverage cans are widely used in terms of design, light-blocking properties, storage stability and transportability due to metallic luster, impact resistance, excellent manufacturability, and above all, recycling.

In general, the beverage can is formed in a cylindrical shape and has a opener and a lid on the upper surface.

Thus, by opening the lid using the opener, the user can drink the beverage stored inside the beverage can.

However, the general beverage cans are difficult in shape at the time of manufacture and in order to use the opener, the manufacturing cost is greatly increased and manufacturing productivity is reduced.

In addition, the user needs more than a certain amount of force in order to use the opener, weak children, the elderly and women may experience great inconvenience in use.

In addition, since the force is applied when opening the lid, the beverage can is shaken and the beverage is discharged to the outside to contaminate the surroundings, there is a problem that the opener penetrates into the drinking water inside the opener when a large force is applied to the opener.

In order to solve this problem, a beverage can opener as shown in FIG. 1 has been invented.

Referring to the drawings, the opening is formed on the upper lid 14 of the beverage can 10 and is coupled to be easily cut by external pressurization while closing the beverage outlet 14a through which the beverage is discharged. And an opening lid 14b to be provided, and a sticker 15 'attached to the upper lid 14 so as to completely cover the opening lid 14b and having a larger area than the opening lid 14b.

The opening lid 14b is formed with a thin thickness portion, a perforated line, or the like formed on the outer circumference so as to be easily cut even at a relatively small external pressure.

Of course, a portion of the outer periphery of the opening lid 14b is not formed by a thin thickness or a perforation line, so that it is open to be flipped when it is pressed and opened, and can be held in the open state and suspended from the upper lid 14.

However, there have been the following problems in manufacturing by the conventional method as described above.

When a tear line is formed with a press except for a part of the outer periphery of a thin aluminum plate so that the tear cover can be easily cut even at a relatively small external pressure, the opening lid 14b is opened and closed along the tear line to the aluminum plate by the pressure of the press. Or when the pressure of the press is weak, the tear line is not properly formed, and the user has a considerable difficulty in opening and closing the opening lid 14b.

Accordingly, there is a problem that the loss caused by the difficulty of manufacturing and increase the defective rate in manufacturing the opening lid 14b of the beverage can.

The present invention has been made in order to solve the above problems, it is possible to omit the bark, a large profit in the manufacturing cost and production productivity, while the wrong piece of metal generated when the opening is separated in the wrong opening It is an object of the present invention to provide a method for forming a beverage can outlet, which can be prevented from penetrating into the interior.

Drinking water cans outlet forming method of the present invention for achieving the above object, the step of coupling the plate to the fixed protrusion to form the upper surface of the beverage cans; Lowering the pressing rod of the upper press so that a blowout part is formed in a portion of the upper surface of the plate; Pressing the lower blade of the upper press to form a recess recessed around the outlet; Elevating the lower press to the upper portion of the ejection portion protruding downward; And discharging the plate to the outside from the fixed protrusion. It includes.

Preferably, bonding the silver foil on the lower surface of the plate closely coupled; And

Bonding polyethylene resin to the upper surface of the sheet to which silver foil is adhered; To

It includes more.

Also preferably, the fixed protrusion is seated on the plate; An upper press provided at an upper portion of the fixed protrusion and having a lowering operation, and having a pressurizing rod inside and a pressurizing blade outside; And a lower press provided below the fixed protrusion to raise the ejection part of the plate with a flat cross section. It may be made of.

Also preferably, it may be provided with a lid formed using the beverage can outlet device.

According to the present invention, since the use of the barnacle, the manufacturing cost of the beverage can can be significantly reduced, and the effect of preventing the loss by greatly improving the production productivity without a defective rate and difficulty of manufacturing can be achieved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
