Device for protecting and preserving a substance in a container
View Patent ↗Disclosed is a device for protecting and preserving a substance in a container. The device may include a plurality of overlapping sectors capable of rotating about a pivot point such that the device has a substantially disc shape when fully expanded and a substantially pie shape when partially expanded; and a lip defining an outer diameter of the device when fully expanded. The outer diameter of the device is equal to or greater than an inner diameter of the inner surface of the container.
1. A device for protecting and preserving a substance in a container, said device comprising:
at least three non-planar overlapping sectors capable of rotating about a pivot point such that the device has a substantially disc shape when fully expanded and a substantially pie shape when partially expanded;
wherein said at least three non-planar overlapping sectors provide substantially no gaps or holes through the fully expanded device; and
a lip defining an outer diameter of the device when fully expanded;
wherein each of the at least three non-planar overlapping sectors comprises a sector base connected by a flexible arcuate or annular sidewall to the lip,
wherein the device is configured to fit within an associated container to create a substantially airtight seal.
2. The device of claim 1 , comprising three non-planar overlapping sectors.
3. The device of claim 1 , wherein an out diameter of the device is configured to be equal to an inner diameter of an inner surface of the associated container.
4. The device of claim 1 , wherein an outer diameter of the device is configured to be greater than an inner diameter of an inner surface of the associated container.
5. The device of claim 1 , wherein the arcuate sidewall curves upward to the lip.
6. The device of claim 1 , wherein the arcuate sidewall curves outward toward the lip.
7. The device of claim 1 , wherein the sector base is recessed below the arcuate sidewall.
8. The device of claim 1 , wherein the at least three non-planar overlapping sectors interact with one another so as to provide a substantially retentive abutment between adjacent overlapping sectors.
9. The device of claim 1 , further comprising at least one finger grip.
10. The device of claim 1 , further comprising a detent, a latching tab, and a finger grip, each of the detent, the latching tab, and the finger grip being on at least one, two, or three of the at least three overlapping sectors.
11. The device of claim 1 , further comprising a finger grip on at least one of the at least three overlapping sectors.
12. The device of claim 1 , further comprising a step-down portion on at least one of the at least three overlapping sectors.
13. The device of claim 1 , wherein each of the at least three overlapping sectors comprises a leading edge and a trailing edge, and said leading edge includes a ridge, said trailing edge includes a rotation stop, and the trailing edge includes a ridge.
14. A device for protecting and preserving a substance in a container, said device comprising:
(a) a plurality of overlapping sectors capable of rotating about a pivot point such that the device has a substantially disc shape when fully expanded and a substantially pie shape when partially expanded;
wherein at least one, two, or three of the plurality of overlapping sectors further comprises a detent, a latching tab, and a finger grip; and
(b) a lip defining an outer diameter of the device when fully expanded;
wherein the device is configured to fit within an associated container to create a substantially airtight seal.
