Abstract

A container for storing at least two substances separately, for subsequent mixing, comprises two storage chambers. Both substances are maintained separately through means of an intervening seal that in one embodiment includes molded threads on its inner walls, a breakable bottom, and a seal rim portion. Activation occurs when the first chamber is screwed downward toward the second chamber. A second embodiment includes the same seal, but with no threads and simply a press activation system within a bellows sleeve. The first chamber may include various cap means through which the mixed substances may be poured out, including screw, spouted, snap-fitted, and plug-types. The seals of both embodiments may be reconfigured into two parts to adapt to a modified second chamber to accomplish the same results. The container may be enclosed in tamper-evident film that includes a perforated pull strip. Both embodiments can be adapted for beverage, medical, cosmetic, chemical, and many other container applications.

Claims

1. A container having at least two separate storage chambers for storing at least two substances separately, for subsequent mixing, comprising:

(a) a first container portion forming a first chamber that may enclose a first substance;

said first chamber further comprising an open end and a seal mating portion, on its outer periphery, proximate to said open end;

said first chamber'"'"'s open end further having a seal breaking element;

(b) a second container portion forming a second chamber that may enclose a second substance;

said second chamber further comprising an open end and a seal mating portion at said open end;

(c) a seal situated between the said open end and seal mating portion of first said chamber and situated between the said open end and seal mating portion of second said chamber whereby said seal simultaneously seals said first and said second substances from one another, structurally co-joining said first and second chambers as a single said container with said first and second substances in an unmixed state;

(d) said seal further comprising a breakable seal bottom which is broken as said first and second chambers are linearly moved with respect to each other, thereby enabling said seal breaking element to move down upon and break open said seal bottom, allowing said first and second substances to mix together as said first and said second seal mating portions meet;

said container thenceforth maintaining said mixed substances in the sealed, said container, until releasing said mixed substances.

2. The container as recited in claim #1 whereby said seal further comprises an annular cavity having an annular seal rim portion, and inner walls further having internal threads thereon;

said container'"'"'s said first open end'"'"'s said outer periphery of said first chamber further comprises external threads that rotatably mate with said seal'"'"'s threads, enabling the said first and second chambers to move together linearly when the said first and said second chambers are rotated with respect one another, thus enabling said seal breaking element to break open said seal bottom.

3. The container as recited in claim #1 wherein the said seal braking element further comprises a lower extremity, whereby at least one cutting edge is formed on said first chamber'"'"'s open end.

4. The container as recited in claim #2 wherein both the said seal'"'"'s and the said first chamber'"'"'s threads are multiple-lead threads, enabling a long linear travel distance of said seal breaking element through a minimal said rotation requirement of said first and second chambers with respect to one another.

5. The container as recited in claim #1 wherein said first chamber comprises a second open end located opposite the end of said first chamber'"'"'s first opening;
