Field of the Invention: The present invention is a dual structure can, in detail, which is devised to enable the user to easily blend and consume blended liquor.

Description of the Prior Art : The present invention is a dual structure can devised to manufacture blended liquor. In detail, a detachable mini-container is attached inside the beer can, which is sealed up containing a second liquor or beverage. Therefore, the user is able to make and consume blended liquor easily using this dual structure can when willing to mix and drink two different beverages.

Generally, blended liquor is made by pouring and mixing two or more different liquor or beverage in turn in a container.

Blended liquor is regarded as a common way of drinking amongst The habitual drinkers, and the want for blended liquor has been continuous for a long time. However, since more than two beverages are needed when blending liquors and it is considerably difficult to match the adequate ratio, difficulties reside in creating blended liquor with the best ratio.

Especially, as for the widely spread beer can, an additional container is needed in order to make a blended liquor, not mentioning a second beverage, and since it is difficult

to obtain an additional container at general situations and the second beverage must be purchased by bottles, the situation is likely to turn out to be wasting too much beverages than necessary.

In accordance to the background mentioned above, the present invention is devised to solve the problems revealed. It is to provide a dual structure can which enables manufacturing blended liquor easily at any time or place, with the detachable mini- container sealed up containing a second beverage, attached to the inner side of the beer can.

Another aim of the invention is to provide a dual structure can which is capable of storing the best amount of the second beverage according to the amount of the beer in the main container and enables the user to manufacture blended liquor at the best ratio.

SUMMARY OF THE INVENTION In order to accomplish the aims mentioned above, the dual structure can devised to manufacture blended liquor is provided, which comprises: said cylindrical main container accompanied by a lid sealing the upper opening of the container, and said mini- container which is attached to the bottom side of the main lid and placed inside of the main container. The first aperture is formed on the said main lid, and a second aperture is formed on the upper face of the said mini-container, where a detachable opening assembly is equipped so that it can seal the first and second aperture at the same time.

In this case, the said opening assembly comprises; the pressure assembly which

is divided into two sections; the handle section where the user may insert a finger to apply pressure, and the pressure section by which direct pressure is inflicted to the first sealing assembly, and the said first sealing assembly which is placed below the said pressure assembly with the shape and thickness corresponding to that of the first aperture on the main lid and therefore constituting its seal, which also has a flap for the first opening when consuming the beer only, and the second sealing assembly which is placed below the said first sealing assembly with the shape and thickness corresponding to that of the second aperture on the mini-container and therefore constituting its seal, and the rivet assembly which integrates the pressure assembly, first sealing assembly and second sealing assembly into a single unit and which also functions as a fulcrum of the said pressure assembly.

In accordance with one aspect, on opening the flap of the first sealing assembly, in order to limit the folding angle of the flap, the upper edge of the mini-container mentioned above is inclined to form a slant.

As shown in Fig. 1 or Fig. 2b, the dual structure can of the present invention comprises: a mini-container (40) attached to the inner side of the lid (20) which is placed inside the cylindrical main container (30), the opening assembly (50) which is attached from the said lid (20) to the upper part of the mini-container (40).

Fig. 3a is the magnified perspective view of the opening assembly of the dual structure can of this invention, and Fig. 3b the perspective view of Fig. 3a from the bottom, and Fig. 4 is the cross-sectional view of the dual structure can according to the execution example of this invention.

As described in Fig. 3a or Fig. 4, the first aperture (23) is formed on the said main lid (20), and the second aperture (43) is formed on the upper face of the mini- container (40), where the detachable opening assembly (50) is equipped so that it can seal the first aperture (23) on the lid (20) and second aperture (43) on the mini-container (40) at the same time.

The said first aperture (23) is to be used when consuming beer or other beverages in the main container, and the said second aperture (43) is to be used when a second beverage is to be discharged into the main container (30).

In this case, the said opening assembly (50) is an apparatus to open the beer can when drinking the beer only, or the blended liquor of beer mixed with a second beverage, which is integrated into a single unit by the rivet assembly (52), and is composed of the pressure assembly (53), the first sealing assembly (55), and the second sealing assembly (57).

The said pressure assembly (53) is mounted on the very top of the opening

assembly (50), which is composed of the handle section (53a), where the user may insert a finger to add pressure, and the pressure section (53b), which inflicts direct force.

Meanwhile, the said pressure assembly (53) will use the rivet assembly (52) to accomplish its task.

The first sealing assembly (55) is on the lower part of the pressure assembly (53) and seals the first aperture (23) of the said main lid (20). Therefore, the first sealing assembly (55) has the same shape and thickness of that of the said first aperture (23), where a flap (56) is arranged on one side which is used on the first opening when consuming only the beer.

Furthermore, the second sealing assembly (57) is attached below the said first sealing assembly (55) which seals the second aperture (43) on the mini-container (40).

Likewise, the second sealing assembly (57) has the same shape and thickness of that of the second aperture (43).

And when the flap (56) of the first sealing assembly (55) is opened, the folding angle of the flap is limited since a certain edge of the upper part of the said mini- container is inclined to form a slant in order to block the flap on contact.

On the contact line where the opening assembly (50) and the first aperture meets, a first perforated line (21) is formed for easy opening, and likewise on the contact line where the opening assembly (50) and the second aperture meets, a second perforated line (41) is formed for easy opening.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a specific description of the operation of the dual structure can for manufacturing blended liquor according to this invention will follow.

As described in Fig. 5, in the case of executing the first opening in order to drink only the beer and not the blended liquor, the handle section (53a) of the opening assembly (50) should be raised upwards, and the pressure section (53b) will push the flap (56) due to lever action on the first sealing assembly (55). Then, the flap (56) will open tracing a certain length of the first aperture (21) and be pushed into the main container (30), where the folding will stop when it meets the slant (45) of the mini- container (40). Thereby, the first aperture (23) is partially open and the dual structure can is ready to discharge only the beer.

Meanwhile, on making and consuming blended liquor, the second opening is executed by pulling the handle section (53a) backwards from the first opening status, where the pulling force will transmit to the rivet assembly (52), and go on to the first sealing assembly (55), further going on to the second sealing assembly (57), and finally fully opening the first sealing assembly (55) and the second sealing assembly (57), thereby being separated completely. When the second sealing assembly (57) is detached from the said mini-container (40), the mini-container (40) will submerge to the bottom of the main container (30) losing every support, and then the contents of the mini-container (40) will flow into the main container through the second aperture (43), thereby blending with beer.

Therefore, the blended liquor of beer and the second beverage can be consumed through the fully open first aperture (23).

INDUSTRIAL APPLICABILITY As mentioned above, the present invention which is the dual structure can has a merit that it enables manufacturing a blended liquor easily at any time or place, with the detachable mini-container sealed containing second beverage, which is attached to the inner side of the beer can, and that it is capable of storing the best amount of the second beverage according to the amount of the beer and therefore enable the user to manufacture blended liquor with the best ratio.

Meanwhile, since the examples of execution described above are that of the most proper ways of usage, it is obvious they are not limited to these examples and one who has the knowledge of this area can try to transform and remake this invention diversely within the range and aspect of this invention stated in"What is claimed is"following below.
