DISPOSABLE INSTANT MIX ALL CONTAINER
Abstract
A container comprising a sealed outer envelope containing a
powered substance, a sealed inner envelope disposed within the
first sealed envelope and containing a liquid, a combination
piercing means and nozzle integral with the second envelope for:
(1) piercing the second envelope to permit the liquid to escape
therefrom and to mix with the powder; (2) piercing the second
envelope, and (3) serving as a nozzle for dispensing the resultant
mixture from the container.

Claims
I claim:
1. A container comprising a sealed outer envelope containing a
powdered substance,
a sealed inner envelope disposed within the sealed outer envelope
and containing a liquid;
unitary means for:
a. piercing the inner envelope to permit the liquid to escape
therefrom and to mix with the powder;
b. for piercing the outer envelope; and
c. for serving as a nozzle for dispensing the resultant mixture
from the container;
the unitary means being a combination piercing tool and nozzle
formed integrally with the inner envelope,
and being disposed within the inner envelope during the container
nonuse condition,
and being disposed outwardly of the inner and outer envelopes
during the container use condition; and
the inner and outer envelopes being formed from a soft pliable
plastic material.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
Compartmented or plural packages containing different materials
which, when mixed, form still another material.
2. Description of the Prior Art
The prior art teaches means for intermingling or mixing the
contents of one compartment or container with those of another.
However, I am unaware of a plural compartmented container wherein
the means for affording communication between compartments also
serves as the nozzle for dispensing the resulting mixture.
SUMMARY OF THE INVENTION
A primary object of the invention is to provide an inexpensive,
disposable package which contains all of the necessary ingredients,
in the correct proportions, for mixing such as cement or patching
plaster, and having means for permitting not only the ready mixture
of the ingredients but also easy dispensing thereof.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is an elevational view of a container embodying the novel
features of the invention;
FIG. 2 is a longitudinal cross-sectional view taken through the
container of FIG. 1; and
FIG. 3 is a view similar to FIG. 2 showing the container in its
ready-to-dispense phase.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The container includes an outer sealed envelope 10 preferably
formed of a soft, pliable plastic sheet material, such for example,
as polyethylene, vinyl or acetate and containing a powdered
material 12, which may be such as pour rock powder, plaster of
paris, or the like.
Disposed within the outer envelope is an inner sealed envelope 14
formed from like material and containing a liquid 16 which may be
water or any other substance required to mix with powdered material
12.
The two envelopes preferably contain the exact proportions of
powder and liquid to produce a desired amount of mix, whatever it
may be.
Envelope 14 may be secured to envelope 10 or the two envelopes may
be separated one from the other.
Envelope 14 is provided with an integral piercing tool 18 which may
be formed from plastic or metal and which extends inwardly into the
interior of the envelope as shown.
The piercing tool comprises a head 20 fixed to envelope 14, and a
hollow shank 22 which terminates at its inner end at a sharp point
or apex 24. A thin membrane 25 is stretched across the head to
preclude entry of the powdered material 12 into the shank 22.
When the container is grasped by the hands and pressure of the
fingers applied to head 20 of the piercing tool, the point thereof
pierces the wall of envelope 14 as shown at 26 in FIG. 2, thereby
permitting liquid 16 to escape from envelope 14 and to mix with
powdered material 12 of outer envelope 10 to provide mixture 28 of
FIG. 3.
After the mixture has been kneaded to the desired uniform
consistency, the point of the piercing tool is then forced through
the wall of outer envelope 10 and pressure is applied to head 20 so
that the shank 22 slides outwardly to a position exteriorly of the
outer envelope as shown in FIG. 3.
Point or apex 24 is now snipped off to provide a spout 30 through
which mixture 28 may be dispensed by squeezing the outer envelope,
the membrane 25 first having been ruptured with a pin, small nail
or the like.
