INSULATING CONTAINER COVER
Abstract
An insulating container cover to encompass a pop top beverage
can to keep the contents of the can cool after removal from the
refrigerator. The insulating cover is formed of flexible styrofoam
plastic and has the same general cylindrical shape as the container
it is to cover. The cover has an opening formed in the upper
portion of its side wall and its top wall to give access to the
drink opening in the beverage container so that the insulating
cover can be left on the container while drinking the beverage
therefrom. The cover is open at the bottom to permit it to be
slipped easily over the beverage container and has a series of
inwardly extending bosses for engaging under the bottom edge of the
beverage container to secure the cover to the container. After the
container has been emptied the cover is slipped off for reuse and
the container is discarded in the usual fashion.

Description
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to the provision of a stay cool
container by covering it with an insulating jacket.
Summary of the Invention
The present invention relates to a generally cylindrical cover
having an open bottom and a closed top. The top and the upper edge
of the side wall have an opening formed therein to permit access to
the drink opening of a container positioned within the cover. A
plurality of bosses are formed on the inner face of the side wall
adjacent the open bottom thereof to engage under the lower edge of
the beverage container to detachably secure the beverage container
within the cover.
The primary object of the invention is to provide an insulating
cover for beverage receptacles which can be easily removed and
reused.
Other objects and advantages will become apparent in the following
specification when considered in the light of the attached
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an exploded perspective view of the invention;
FIG. 2 is an enlarged vertical sectional view, taken along the line
2--2 of FIG. 1, looking in the direction of the arrows; and
FIG. 3 is a bottom plan view of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in detail, wherein like reference
characters indicate like parts throughout the several figures, the
reference numeral 10 indicates generally, an insulating beverage
container cover constructed in accordance with the invention.
The cover 10 is intended for use with generally cylindrical
beverage containers 11 of the type having a circular bottom 12 and
a circular top 13. The beverage container 11 is of the type having
a pop top 14 to form an opening to permit the user to drink the
beverage therethrough.
The cover 10 includes a generally cylindrical side wall 15 having a
generally circular top wall 16 integrally formed thereon.
An arch shaped access opening 17 is formed in the top wall 16 by a
pair of intersecting curved edges 18, 19. The opening 17 connects
with an opening 20 formed in the upper top edge of the side wall
15.
A plurality of bosses 21 are integrally formed on the inner face of
the cylindrical side wall 15 spaced upwardly from but adjacent to
the lower edge 22 of the side wall 15.
The cover 10 may be made of any flexible insulating material and I
have found styrofoam plastic to be particularly advantageous.
In the use and operation of the invention the container 11 is
removed from its cooler such as a refrigerator and the cover 10 is
pressed downwardly thereover until the bottom edge 12 of the
container 11 is slightly above the bosses 21 so that the container
11 is held in the cover 10 to prevent its accidental dislodgment
therefrom. When it is desired to drink the beverage from the
container 11 the pop top 14 is opened and the container 11 is
positioned so that the opening therein is aligned with the opening
17 in the top wall 16 to permit the user of the invention to drink
the contents of the container 11 while keeping the insulating cover
10 in place thereon.
After the container 11 has been emptied the cover 10 is forceably
slid off of the container 11 and may be reused on another container
as desired.
Having thus described the preferred embodiment of the invention it
should be understood that numerous structural modifications and
adaptations may be resorted to without departing from the spirit of
the invention.
