INSULATED CONTAINER PACK
Abstract
A hand-carriable, insulated container pack for holding the
temperature of food or drink containers for several hours without
the use of either a hot or cold agent. Specifically, the container
is a Styrofoam block having six independent thermal chambers which
seat six upwardly open cups. These cups hold a twelve-ounce beer
(beverage) or food can, or a standard throwaway glass beer bottle.
The lid is likewise a block of Styrofoam with cavities matching the
thermal chambers in the lower block and a rope bail is the means
for holding the lid to the base when it is carried.

Claims
We claim:
1. A food and/or beverage pack for holding food or drink containers
comprising a block of low thermal conductivity material, said block
having a plurality of cavities therein, said cavities being
upwardly-open through the upper surface of said block and being
adapted to seat cups therein, cups for holding said containers made
of low thermal conductivity material seated upwardly-open in each
said cavity, the height of said cups being such that a cup holding
a container may be picked up with the container in the cup and the
container will continue to be insulated from the hand and the
atmosphere, said cups constructed for seating and exposing
containers so that human lips may engage their rims without
engaging the cups, and a lid having downwardly directed cavities
matching those in said block and being directed through the bottom
of the underside of said lid, said lid cavities being capable of
receiving the tops of said containers and cups and having shoulders
seatable on the rims of said cups when said cups are seated in the
matching block cavities, said underside surface of said lid seating
essentially flush on the upper surface of said block so that said
matching block and lid cavities form independent thermal
cavities.
2. An insulated container pack comprising:
a. a base formed of a material of low thermal conductivity,
b. a plurality of upwardly opening cavities in said base extending
downwardly into said base from an upper surface thereof,
c. a lid formed of a material of low thermal conductivity,
d. said lid having a lower surface abutting said upper surface of
said base,
e. a plurality of downwardly directed cavities formed in said lid
in registration with said cavities in said base,
f. a plurality of upwardly opening cups formed of a material of low
thermal conductivity,
g. said cups having a height greater than the depth of the base
cavities,
h. said cups having an outside diameter slightly less than and
being received in said base cavities,
i. said cups extending from said base cavities into opposed lid
cavities and forming independent thermal cavities of each opposed
pair of base and lid cavities,
j. said outer diameter of said cups being approximately equal to
but slightly less than the inner diameter of said lid cavities
thereby forming a thermal barrier between opposing portions of the
outer surfaces of said cups and the inner surfaces of said lid
cavities, and
k. upper portions of said lid cavities extending upwardly beyond
upper rims of said cups and accommodating upper ends of containers
seated in said cups and projecting above said upper rims
thereof.
3. The pack of claim 2 further comprising:
a. aligned pairs of holes through said lid and said base, and
b. a rope bail extending through said holes to facilitate carrying
of said pack.
4. The pack of claim 2 further comprising:
a. interfitting, peripheral flange and shoulder means formed on
said lid and said base to minimize air leakage into and out of said
pack.
5. The pack of claim 2 wherein the material of low
thermal-conductivity is Styrofoam.
Description
BRIEF SUMMARY OF INVENTION
The invention resides in a block of low thermal-conductive material
having six independent thermal chambers within which are cups made
of like material each of which holds a standard twelve-ounce can or
bottle with a rope bail for carrying such a container pack. The
ingredients within the cups can be kept hot or cold simultaneously.
This invention is not to be limited to twelve-ounce cans/bottles
but also applies to any capacity thermal chamber which for example
could maintain the temperature of hot baked beans and cold potato
salad simultaneously for picnic purposes.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a perspective view of the pack with one unopened beer can
in the pack and one opened beer can in a cup that has been removed
from the pack;
FIG. 2 is a front elevational view with portions of the lid and
base broken away;
FIG. 3 shows the two ends of the rope bail being held by one hand;
and
FIG. 4 shows the pack with the rope bail slung over the
shoulder.
DESCRIPTION OF THE INVENTION
Referring to the drawings, the numeral 10 identifies a block of
insulating material, in this case, Styrofoam, but need not
necessarily be so. In the block are six upwardly open cavities such
as 12, the diameter of which is slightly greater than the outside
diameter of the cups such as 14. These cups have an integral bottom
and are likewise made of Styrofoam but need not necessarily be so.
The inside diameter of the cups is slightly in excess of the
greatest outside diameter of the standard twelve-ounce throwaway
beer bottle. The depth of the cup is sufficiently less than the
height of the same so that one may drink directly from an open can
as 18 without the lips or the chin engaging the cup.
A lid made of insulating material such as Styrofoam has a
peripheral flange 22 which seats snugly on the shoulder 24 of the
base so that a minimum leakage of air between the wall 26 and the
shoulder 24 and flange 22 occurs. The surface 28 on the underside
of the lid seats flush on the surface 30 of the upper side of the
base. Six upwardly directed cavities such as 32 are mounted in the
lid and each possesses one step 34 which seats on the upper rim 36
of a cup. By the cups extending from the base into the lid, the six
independent thermal cavities are formed. At the top level of the
can, there is a truncated cone 38 which accommodates the throwaway
beer bottle which is slightly taller than the can.
A pair of holes 40 vertically through the base are in alignment
with a pair of similar holes 42 through the lid, see FIG. 3. The
external opening of all of the holes is slightly chamferred as at
44 so as to facilitate the bending of a rope bail 46. The rope bail
is a simple 6 foot length of rope. The ends 48 and 50 are either
knotted or held together by any suitable fastening 52. Between the
base and the lid, there are no hinges.
FIG. 3 illustrates the hand carry where a single hand holds two
loops of the rope which is substantially centered in the bottom of
the base. FIG. 4 illustrates the shoulder carry where one loop 54
of the rope bail 46 is over the man's shoulder while the other loop
56 lies in a transverse channel 58 in the bottom of the base, see
FIG. 2.
The advantages of the applicants' pack are several. Firstly, the
provision of six independent thermal chambers to hold insulating
cups has the effect of improving the practicability of inserting a
warm can or bottle in a base along with a cold can or bottle. A
fisherman likes to have a can of hot boullion, as well as a can of
cold beer. Another advantage is that the pack, due to its unique
design, does not require the use of a cooling or heating media to
maintain the desired temperature. Thus, the cost and inconvenience
of such products as ice are avoided. Another advantage is that the
separate cups do not drain the heat or cold from fingers and hands
into the can or bottle when picked up as they will continue to
insulate the beverage from the atmosphere while outside the pack. A
fisherman may spend considerable time emptying a can/bottle which
he removes several times from the pack and returns to the pack
which he closes. The important warming or cooling factor would be
the fingers and the atmosphere, and the cup protects against both
as well as protects the hands from either hot or cold. Another
advantage of the cup is the fact that the depth of the cup is less
than the height of the can or bottle, so that one may apply his
lips to the edge of the can or bottle without encountering the cup.
As for the rope bail, it has a dual purpose. If one has a free
hand, the hand carry of FIG. 3 may be used. However, if one does
not have a free hand, the pack may be slung over the shoulder as in
FIG. 4, and all that is needed is some steadying force while
walking with it.
