Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can of beverage and an end plate of the can.

[0002]

2. Description of the Related Art A convenient opening structure for canned beverages is to open a drinking mouth by pulling a knob attached to an end plate to peel off a part of the end plate (pull tab). Any one of the ones in which a knob is raised and a part of the end plate is pushed into the can to open a drinking mouth by the principle of the lever (Stein tab) is practically used.

According to the above two open-can structures, the upper lip and the lower lip touch the end plate from the upper end of the can when drinking directly from the can. For canned beverages taken out from the vending machine, dust accumulated at the outlet of the vending machine adheres to the canned beverages, and when storing and transporting the cans and filling the canned beverages into the vending machine,
The operator's hand directly touches the can. Canned drinks sold over the counter,
Others' hands directly touch the cans during display and sale.

As described above, another person's hand directly touches,
It is unsanitary for lips to come into direct contact with dusty cans. Also, conventional canned drinks cannot be closed once the cans are opened, so the leftover drinks will be discarded.
There was a waste.

Further, the canned beverage is contained in the full capacity of the can, and can be spilled from the drinking mouth by tilting the can a little.
Therefore, even if the opened can is set in the can holder of the automobile, the vibration of the automobile may spill the beverage and stain the surrounding area.

According to the present invention, a drinking port with a cap is provided so that it can be depressed and projected from the surface of the end plate. When the worker touches the can, such as when filling canned drinks into the vending machine, the drinking mouth is not touched by the hand, and the drinking mouth is recessed from the end surface of the can, so it is put into the vending machine. The mouth will not be a hindrance when you do this. At the time of drinking, you can pull out the mouthpiece from the end plate, remove the cap of the mouthpiece, and drink from the mouthpiece.
Therefore, it is hygienic and can be stored with a cap even if it is left over. Further, since the capacity of the can is increased by pulling out the drinking mouth, the can can be largely tilted until the beverage spills, and a can and an end plate of the can which can solve the problem of the spill of the beverage are disclosed. .

[0007]

The end plate (2) of a can of the present invention is a thin metal plate or a plate made of synthetic resin, in which a recessed portion (3) which is closed stepwise and is narrowed is formed, and the recessed portion (3) is formed. At the bottom of (3),
A cylindrical drinking port (4) is projected upward at a height that can be accommodated in the recessed portion, and a cap (5) is detachably attached to the drinking port (4). Further, the can of the present invention has the above end plate on one end surface.
It is the implementation of (2).

[0008]

[Action and effect] The canned beverage has its mouth (4) housed in the recessed portion (3) of the end plate (2) and has no protrusions to the outside. It can be handled just like a conventional can. Further, as described above, the cap (5) is attached to the drinking mouth (4) so that the drinking mouth (4) is touched by another person's hand,
It is extremely hygienic without dust. Drinking mouth
The withdrawal of (4) increases the volume of the can, and even if the can is tilted a little, the drink does not reach the drinking mouth (4), so the drinking mouth (4)
It is possible to prevent the drink from being tilted and the clothes to be soiled until it sticks to the. Even if the can is set in the can holder of the automobile, the beverage will not fall.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, after filling a cylindrical can body (1) with a bottom with a beverage, the opening of the can body (1) is curled with a circular end plate (2). It is airtightly closed.
The can body (1) and the end plate (2) are made of aluminum or steel thin plate.

A recess (3) is formed in the center of the end plate (2) by pressing, and the recess (3) is gradually narrowed from the opening edge to the bottom, and the bottom has a recess. A cylindrical spout (4) is provided so as to project upward at a height that can be accommodated in the section. Dent
The peripheral walls (31) and (31) in (1) and (1) have a circular closed curve, and the bottom side has a taper with a reduced diameter. By pulling the drinking mouth (4) in the projecting direction, the recessed portion (3) extends in a bellows type and symmetrically jumps outward as shown in FIG.

An external screw is formed on the drinking port (4), and the cap is
(5) is detachably screwed. A knob (6) is fixed to the upper surface of the cap (5) by a rivet (7). The knob (6) is formed in an elliptical shape extending to both sides,
Holes (62) (62) for fingers are provided on both ends of the ellipse.

Between the rivet (7) and the holes (62) (62), perpendicular to the longitudinal direction of the knob (6), there is a narrow groove (61) (6) for bending.
1) is formed by press molding. Above knob
(6) is housed in a space lower than the upper edge of the end plate (2) and the winding edge (21) of the can body (1).

However, in the canned beverage, the mouthpiece (4) is an end plate.
There is no protrusion to the outside that fits inside the recessed part (3) of (2), so there is no hindrance to sales at vending machines. When drinking,
Both ends of the knob (6) are bent upward from the bent narrow groove (61) (61), and the fingers are hooked in the holes (62) (62) and pulled.

The recessed portion (3) of the end plate (2) which is gradually recessed,
It extends in a bellows manner and projects in a conical diameter, with the drinking spout (4) located at the upper end of the conical shape. Peripheral wall (31) with one step and one step of the recess (3)
Since the bottom side has a taper with a reduced diameter, the drinking spout (4) can be pulled out by a relatively small pulling force.

Remove the cap (5) from the spout (4) and drink. Since the volume of the can increases due to the withdrawal of the drinking spout (4), the beverage will not spill even if the can is tilted a little. Therefore, even if the can is set in the can holder of the car, the beverage does not spill. It is possible to prevent the beverage from spilling due to the inclination of the can and soiling the clothes immediately after the can is opened and before it sticks to the mouth (4).

Since the mouth (4) is not touched by other people's hands and dust is not attached, it is extremely hygienic. If the drink cannot be completely consumed, it can be stored without spilling by attaching the cap (5) again. Also, when the cap (5) is pushed in, the recessed portion (3) is deformed again and is depressed into an inverted conical shape, so that it can be accommodated in the narrow space of the refrigerator.

In carrying out the present invention, the end plate (2) is not limited to metal, and synthetic resin can be used. Also, the knob (6)
The purpose of this is to make it easy to pull out the drinking spout (4) through the cap (5), but the knob (6) can be omitted by applying an appropriate slip prevention to the cap (5). Cap (5)
Is not limited to the spiral connection and can be freely changed as long as it engages with the detaching function with respect to the drinking mouth (4).

FIG. 4 is a plan view of another embodiment, and FIG. 5 is a cross-sectional view of the embodiment with the drinking spout (4) pulled out. 2 of FIG.
Recessed part (3) formed on the end plate (2) as shown by the dotted line
The opening edge is gradually narrowed to the bottom side, but the circular step portion of one step and one step is gradually eccentric in the radial direction, and the width of the step portion of one step and one step is eccentric. It is gradually narrowing. When the drinking mouth (4) of the canned beverage is pulled out obliquely in the eccentric direction,
As shown by the solid line in FIG. 5, the drinking spout (4) inclines and projects in the eccentric direction of the step portion, making it easier to drink.
