Multiple chamber container with mistake proof administration system
View Patent ↗The present disclosure provides a multiple chamber container that includes a container body sealed around a peripheral edge and having an outlet. The container also includes a first peel seal having a projecting portion and a second peel seal that isolates the outlet. The second peel seal may also include a projecting portion. The first and second peel seals may be configured to define a symmetrical chamber. The chamber may include an axis of symmetry extending between the first and second projecting portions. The chamber geometry of the container ensures a correct sequential opening of the first and second peel seals.
1. A multiple chamber container comprising:
a container body sealed around a peripheral edge and having an outlet attached to a bottom peripheral edge;
a first peel seal defining chambers in the container, the first peel seal having a first projecting portion and an outer edge, at least a portion of the outer edge having a serrated portion; and
a second peel seal isolating the outlet from the chambers, the second peel seal having a second projecting portion, wherein the first projecting portion projects toward the second projecting portion and the second projecting portion projects toward the first projecting portion substantially symmetrically about an axis of symmetry A that is substantially parallel to at least one of the first peel seal and the bottom peripheral edge.
2. The container of claim 1 wherein the first peel seal has a first peel force and the second peel seal has a second peel force, and wherein the first peel force is less than the second peel force.
3. The container of claim 2 wherein the difference between the first and second peel forces is from about 0.1 N/15 mm to about 15.0 N/15 mm.
4. The container of claim 1 wherein the first peel seal has a peel force from about 10.0 N/15 mm to about 29.0 N/15 mm.
5. The container of claim 1 wherein the second peel seal has a peel force from about 13.0 N/15 mm to about 35.0 N/15 mm.
6. The container of claim 1 wherein the first peel seal has a first activation energy and the second peel seal has a second activation energy, the second activation energy greater than or equal to the first activation energy.
7. The container of claim 6 wherein the second activation energy is from about 1 to about 5 times greater than the first activation energy.
8. The container of claim 6 wherein the second activation energy is from about 1.25 to about 2 times greater than the first activation energy.
9. The container of claim 6 wherein the first activation energy is from about 0.10 Joules to about 0.20 Joules.
10. The container of claim 6 wherein the second activation energy is from about 0.25 Joules to about 0.50 Joules.
11. The container of claim 1 wherein the first projecting portion has a shape selected from the group consisting of arcuate, polygonal, pointed, jagged, triangular, and combinations thereof.
12. The container of claim 1 wherein the second projecting portion has a shape selected from the group consisting of arcuate, polygonal, pointed, jagged, triangular, and combinations thereof.
13. The container of claim 1 wherein the first projecting portion, the second projecting portion, and the outlet are in a substantially linear relation with respect to each other.
14. The container of claim 1 wherein the second peel seal further comprises an outer edge, at least a portion of the outer edge having a serrated portion.
15. The container of claim 1 wherein the second peel seal has opposing ends and the container has a plurality of edges, each end in contact with the same container edge.
16. The container of claim 1 wherein the second peel seal defines an outlet chamber.
17. The container of claim 1 wherein the outlet further comprises an inlet end in communication with the container interior and the second peel seal covers the inlet end.
18. A multiple chamber container comprising:
a container body sealed around a peripheral edge and having an outlet attached to a bottom peripheral edge;
a first peel seal having a projecting portion and an outer edge, at least a portion of the outer edge having a serrated portion;
a second peel seal isolating the outlet, the second peel seal having a second projecting portion, wherein the first projecting portion projects toward the second projecting portion and the second projecting portion projects toward the first projecting portion substantially symmetrically about an axis of symmetry A that is substantially parallel to at least one of the first peel seal and the bottom peripheral edge; and
the first and second peel seals defining a substantially symmetrical chamber.
19. The container of claim 18 wherein the chamber further comprises an axis of symmetry substantially perpendicular to a line extending through the outlet.
20. The container of claim 18 wherein the first projecting portion and the second projecting portion define respective first and second seal contact angles in the chamber, the seal contact angles being substantially similar in size.
21. The container of claim 20 wherein the seal contact angles are less than or equal to about 30°.
22. The container of claim 18 wherein the first peel seal has an activation force less than an activation force of the second peel seal.
23. A method for opening a container having a peelable seal comprising:
providing a container body sealed around a peripheral edge and having: 1) an outlet attached to a bottom peripheral edge, 2) a first peel seal having a projecting portion and an outer edge, at least a portion of the outer edge having a serrated portion, and 3) a second peel seal isolating the outlet, the second peel seal having a second projecting portion, wherein the first projecting portion projects toward the second projecting portion and the second projecting portion projects toward the first projecting portion substantially symmetrically about an axis of symmetry A that is substantially parallel to at least one of the first peel seal and the bottom peripheral edge, and the first and second peel seals defining a symmetrical chamber;
activating the first peel seal; and
activating the second peel seal.
24. The method of claim 23 wherein the first peel seal activation and the second peel seal activation occur in a predetermined sequence.
25. The method of claim 23 wherein the second peel seal activation occurs only after the first peel seal activation.
26. The method of claim 23 further comprising initiating the activating of the first peel seal at the first projecting portion.
27. The method of claim 23 further comprising initiating the activating of the second peel seal at the second projecting portion.
28. The method of claim 23 wherein the first peel seal defines two chambers, each chamber containing a respective component, the method further comprising admixing the components before the further activating.
29. The method of claim 28 further comprising dispensing the admixed components from the outlet.
