## Abstract

An easily openable metal can largely openable in the arranged state of two sheet metal-made cans in series. A means such as a projection for opening the drinking mouth of another can is formed at the lower part of a can body, and a break line and a means for guiding the means such as the projection are formed at the upper part thereof.

## Claims

### Claim 1

An improved liquid storage unit (1) with a large opening capability includes a container formed of a cylindrical body closed by a lid plate (4) at its top and a bottom plate (2) at its bottom-comprising:
a break away section (4a) defined by a break line (8) formed in said lid plate (4) and a socket means (3X, 5, 6) formed above said lid plate; and
wedge means (3a, 3b) formed as part of said bottom plate (2) operable to be received in said socket means and operable to separate said break away section (4a) from said lid plate along said break line (8) by applying pressure on said break line (8) when engaged in said socket means and rotated relative thereto whereby a second improved storage container can be used to open said storage container by placing its wedge means in said socket means and twisting said second container relative to said improved liquid container.

### Claim 2 (depends on 1)

The improved liquid storage container defined in claim 1 wherein the break line (8) is disposed in a circular configuration in the lid plate (4).

### Claim 3 (depends on 1)

The improved liquid storage container defined in claim 1 wherein the length of the break line (8) is from ½ to ⅗th of the length of the periphery of the lid plate (4).

### Claim 4 (depends on 1)

The improved liquid storage container defined in claim 1 wherein the length of the break line (8) traverses approximately 180 degrees of the diameter of the lid plate with its ends intersecting the ends of a fold line (18 or 4c) and said lid plate (4) includes a pull-tab means (10) centrally mounted on said lid plate and operable to fold the break away section (4a) into the container after said break line (8) has been separated from said lid plate when said pull tab is lifted relative to said lid plate.
