KR20010079016A - Food and Beverage CAN with Micro / Flexion-Rim : MFR CAN - Google Patents

Abstract

PURPOSE: A food and beverage can containing micro dimple rim is provided to reduce volume of a wasted can by compressing the can and to improve recycling of the wasted can by conveniently collecting and containing the wasted can. CONSTITUTION: A metal can trunk(1) is produced by repeatedly processing a metal compression roller on a thin metal sheet. A rim is formed on the metal can trunk by using the metal compression roller forming a micro flexion rim. A flange(6) is installed on an upper portion of the metal can trunk to suture. Then, the upper portion of the metal can trunk is sealed by a metal can lid after filling contents into the metal can. The food and beverage can having containing micro dimple rim reinforcing structure of a container. The food and beverage can is firm against inner/outer pressures after sealing the contents. The can easily reduces volume by conveniently pressurizing emptied can. Moreover, the can is improves efficiency of recycling of the wasted can by easily collecting and containing the waste can.

Description

Food and Beverage CAN with Micro / Flexion-Rim: MFR CAN}

The manufacture of conventional food and beverage cans is generally as in (Fig. 4) and (Fig. 5),

-Metal sheet is made into a cylinder to form a metal CAN trunk (1).

-Form a flange (6) on top of the metal CAN trunk (1).

-Fill the contents of the metal can.

Seal the metal can using a metal lid (5) on the flange on the metal can body.

In other words, in the form and structure, only the structure capable of withstanding the force received from the inside and outside of the food and beverage can to protect the contents.

In the prior art, in the manufacture and use of metal cans (Metal CAN) as a container for food and beverage, it is possible to simply hold the contents. Thus, it can only withstand the pressure exerted from inside / outside the metal can.

In other words, storage / treatment of the empty cans (Emptied CAN) as waste cans after using the contents was not considered very much.

However, with the increase of empty cans (waste cans) due to the increased use of metal cans, there is a problem of collection / storage to collect and operate them for recycling. In other words, the volume of garbage occupied by the empty can (waste can) itself is too large. Therefore, inconvenience in collecting / storing waste cans (empty cans) is impaired, and macroscopically lowers recycling of metal cans themselves.

The present invention solves the above problems, and proposes a food and beverage can that can more effectively increase the use of steel and aluminum cans (CAN), which are particularly highly recyclable.

6A to 6E are flowcharts for each process according to an exemplary embodiment of the present invention.

The present invention adds some processes to the food and beverage can manufacturing materials of the prior art and finally (FIG. 1A) / (FIG. 1B) / (FIG. 1C), (FIG. 2A) / (FIG. 2B) / (FIG. 2C) and (FIG. 3a) / (Fig. 3b) / (Fig. 3c) respectively,

Micro Dimple-Rim (2)

Micro Jut-Rim (3)

Micro Indented-Rim (4)

Metal CAN Trunk (1)

Metal CAN Lid (5)

-Flange (6).

In addition, in the case of the food and beverage can of the present invention, as an example of the manufacturing process, as shown in Figs. 6A to 6E,

-Metal can trunk (1) is made by repeating the metal compression roller process on a thin metal sheet. ------ (Figure 6a)

-Using the metal compression roller (Roller) in which the Micro Flexion-Rim is formed to form the Rim (7) required for the metal can body (1). ------ (Figure 6b)

-Form a flange (6) for closure on top of the metal can body (1).

------ (Figure 6c)

-Put the contents (8) in a metal can. ------ (Fig 6d)

-Seal the upper part of the metal can body (1) with a metal CAN lid (5). ------ (Fig. 5e)

The present invention compared to conventional food and beverage cans,

First, by reinforcing the structure of the container,

-It is more robust to the pressure from inside and outside after filling and sealing the contents.

Second, it is easy to press the empty can (Pressure),

-The volume of waste cans can be minimized.

Third, it is easy to collect / store waste cans,

-Can improve the recycling rate of waste cans.

Claims (4)
