DISPOSABLE INSTANT MIX ALL CONTAINER BACKGROUND OF THE INVENTION SUMMARY or 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. 1
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is an elevational view of a container embodying the I novel features of the invention;
HO. 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 I preferably formed ofasoft, 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. I
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. 7
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 l4 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 H6. 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.
l. Acontainer 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 noule 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.
