FIELD OF INVENTION
The present invention relates to covers for beverage cans, and to
a method for providing such covers to beverage cans.
The beverage cans, may be of the type having a tear-off lug closing
off a dispensing opening.
BACKGROUND TO INVENTION
Beverage cans often are stored or transported in surroundings which
are not hygienic. The result is that a beverage can may reach the end user in a
condition, which is not only unattractive but is also unhygienic.
It is an object of the invention to suggest ways and means for assisting
in overcoming this problem and, if required, providing additionally or alternatively
a promotional advantage.
SUMMARY OF INVENTION
According to the invention, a cover for a dispensing opening of a
beverage can is characterized by including a disc and an attachment area associated
with the disc for attaching the disc removably to a beverage can for closing off
the dispensing opening of the beverage can.
The disc may have an annular ring joined thereto for attachment to
a beverage can.
The cover may form part of a lid of a beverage can to be applied to
a beverage can after filling of the beverage can.
The cover may be provided with promotional material.
The promotional material may be constituted by a separate member
located adjacent the disc.
Also according to the invention, there is provided a cover for a beverage
can, which beverage can has a cylindrical housing and a lid part at one end of
the cylindrical housing, the cover being characterized by including a disc constituted
by a disc part and a circumferential collar formed integrally therewith, the collar
being adapted to fit tightly against an end of the cylindrical housing of a beverage
can so that the disc part covers the lid part of the beverage can.
The cover may be provided with a tongue for removal from a beverage
can to which the cover is fitted.
Further according to the invention, there is provided a cover for
a beverage can, which beverage can has a cylindrical housing and a lid part at
one end of the cylindrical housing and a raised rim circumferentially surrounding
the lid part, the cover being characterized by including a disc constituted by
a disc part, the disc part being adapted to be fitted over the lid part of a beverage
can between the circumferential raised rim of the beverage can so that the disc
part covers the lid part of the beverage can.
Yet further according to the invention, a method of covering a dispensing
opening in a lid of a beverage can includes the steps of attaching a cover as
set out above to a beverage can for closing off the dispensing opening of the beverage
can, the method being characterized by suitably placing the cover over such a dispensing
opening; and of joining the cover removably to the beverage can.
The method may further include the step of providing a separate member
between the cover and the lid of a beverage can. The separate member may include
any promotional or other information.
The disc may be made of thin and flexible material, for instance of
suitable sheet metal foil, a plastics foil or a foil made of any other suitable
The disc also may be of a laminated construction comprising at least
two sheets, foils or layers laminated together.
Alternatively, or in addition, the disc may have an annular ring joined
thereto for attachment to a beverage can.
In case of a disc made of plastics material, it may be applied to
a beverage can by heat, glue, laser welding or melting, or merely by frictional
In case of a disc made of metal it may be applied to a beverage can
by mechanical crimping, welding, glueing or merely by frictional fitting.
In the case of a disc made of glass it may be applied to a beverage
can by glueing.
The material of the disc may be bio-degradable to render it environmentally
friendly. It also may be made of edible material and may be tasteless and have
The material of the disc may be such to render the cover illuminous.
The cover may be used for sterilising, protection, decorative, promotion
or for any other purposes.
The cover may form part of a lid of a beverage can to be applied to
a beverage can after filling so as to close the can.
The cover may be applied to a beverage can before filling thereof
or after filling thereof, and, in the latter case, before or after applying a pasteurising
or sterilisation process to the beverage can.
The beverage can may be of round circular shape, and may be made of
suitable sheet metal, for instance tin alloy. The beverage may be a carbonated
beverage. It may be an alcoholic or non-alcoholic drink.
The beverage can can have opposite closed ends, in one end a tear-off
lug being provided for uncovering a dispensing opening.
The cover may function as a trigger for opening the dispensing part
of a can. It may replace the existing trigger of a beverage can or can act as a
lever mechanism for opening a can. It may also be attached to an existing trigger
of a can in order to be partly or wholly used to open a can. It may also be used
as any other mechanism for opening of a can.
The cover may be used as a cover for opened cans in order to stop
spilling and running down of opened beverages.
The cover itself may act as a drinking straw and/or any mouthpiece
for drinking purposes. The mouthpiece may always be visual or only when the cover
is removed from a beverage can. The cover may also be used (for instance torn,
bent, folded) in any way to act as a mouthpiece for drinking purposes.
The cover may be used to attach any items, such as a drinking straw,
a mouthpiece for drinking, a gift, money, a puzzle, chemicals (such as headache
and other pills, medicinal items), a game, a tobacco item, a toy, seeds, safety
material, or any other useful item. These items may be attached underneath, onto
or on top of the body (or between layers).
The cover may be provided with promotional or advertising material,
either on or below the cover itself or as a separate item. A separate member may
be located between the disc and a beverage can to which it is fitted.
Promotional material may be made from any material such as biodegradable
material. The promotional material may be impregnated beforehand for moisture absorption
or sterilizing purposes.

is opened or removed from a beverage can.
The promotional material may be aimed at promoting or advertising
any sport event in any way.
The promotional material may be aimed at promoting or advertising
any project (for instance polio, aids prevention) in any way, for example a condom
may be placed between the can and the lid of a container.
The promotional material may be fixed in any way to the existing trigger
mechanism of a can, that is below, through or on top of the trigger mechanism.
The cover may have any two or three dimensional shape for promotional
The cover may be adapted to release any smell or odour as it is opened.
The smell may be for promotional purposes or may give an indication of the quality
or type of the beverage or any other purpose.
The cover may be layered and may contain any chemicals or combination
of chemicals aimed at cooling or heating the beverage drink or beverage can in
any way. An example is a chemical of which the temperature lowers as it is crushed,
such as used for sport injuries. In this case the cover may be attached to the
bottom of a beverage can or to the top of a beverage can.
The cover or promotional item may be of any colour or combination
of colours. The cover or promotional item may also be transparent or translucent.
The material may also change colours or images under certain circumstances, for
example when it is pressed, rubbed, dropped, or exposed to heat or cold.
The cover material and promotional item can also be used to indicate
the temperature of a beverage in a beverage can. This may be by displaying a colour
or by giving any other visual or perceivable indication.
The cover material or promotional item may also give an indication
of the quality of the beverage in a beverage can. The indication can be visual
or any other means perceivable by humans, such as smelling, feeling, seeing a
colour or any other display.
The cover and promotional item may reflect the age of the beverage.
The cover may reflect the fact that the cover has or has not been
opened or removed before so as to indicate tampering. This is to stop tampering
with promotional items.
The cover may be made of multi-layer material that may be or may not
be fixed to one another. The promotional items may be placed between the layers
of material, or below the layers or on top of the layers of material.
The cover may be impregnated before or after being applied to a beverage
can in order to ensure a sterilized attachment.
The cover may be gas permeable so as to allow breathing.
The cover may screw onto the top or bottom of a beverage can.
The promotional material may be slid onto a beverage can before the
cover is fitted to the can.
The promotional material may be printed or stamped on a beverage can
underneath the cover material.
The cover may be fitted with a tongue or lug for easy opening or partly
or fully removing the cover or for uncovering the promotional material. The tongue
or lug may form part of the cover or may be a separate part which is fixed to a
In some uses the cover should not be easily removable. According to
one suggestion, the cover must be destroyed if it is removed.
A removal strip may be located between the cover and the lid of a
beverage can. The removable strip may extend over one edge of a rim of a beverage
can or over opposite edges of a rim to provide one or two gripping parts for lifting
the cover off a beverage can to which it is fitted. The strip may be made of a
flexible material, for example a thread, a string, a thin rope, a flat strip, a
wire or be of any other suitable form.
Although in the specification reference is made to a "beverage can"
this expression also includes a can containing any other goods, such as foodstuffs.
