## CPC

- B65D 81/22: in moist conditions or immersed in liquids
- B65D: CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR FITTINGS THEREFOR; PACKAGING ELEMENTS; PACKAGES

## Abstract

Aspects of the invention are directed to a container comprising a tub, a basket, and a lid. The tub is adapted to hold a liquid and comprises a bottom and a tub sidewall having an upper rim defining an opening in the tub. The basket is disposed on the bottom of the tub and comprises a base and a basket sidewall. The base defines a perimeter, and the basket sidewall runs along at least a portion of this perimeter. The lid contacts the upper rim and comprises a filler piece. The filler piece occupies a volume inside the tub between the base and a plane defined by the upper rim. The container is adapted to hold a sensitive film stack without damage or degradation to the film stack. The container is further adapted to facilitate the easy transfer of the film stack to a new substrate.

## Claims

### Claim 1

A container comprising:
(a) a tub, the tub adapted to hold a liquid and comprising a bottom and a tub sidewall having an upper rim defining an opening in the tub;
(b) a basket, the basket disposed on the bottom and comprising:
(i) a base, the base defining a perimeter; and
(ii) a basket sidewall, the basket sidewall running along at least a portion of the perimeter; and
(c) a lid, the lid contacting the upper rim and comprising a filler piece, the filler piece occupying a volume inside the tub between the base and a plane defined by the upper rim.

### Claim 2 (depends on 1)

The container of claim 1, wherein the base comprises a fabric.

### Claim 3 (depends on 1)

The container of claim 1, wherein the lid covers the opening in the tub.

### Claim 4 (depends on 1)

The container of claim 1, wherein the filler piece defines a lower surface, the lower surface disposed inside the tub and facing the bottom.

### Claim 5 (depends on 4)

The container of claim 4, wherein the lower surface defines a beveled edge.

### Claim 6 (depends on 1)

The container of claim 1, wherein the basket sidewall runs along only a portion of the perimeter.

### Claim 7 (depends on 1)

The container of claim 1, where the base describes four edges and the basket sidewall runs along only three of the four edges.

### Claim 8 (depends on 1)

The container of claim 1, wherein the basket sidewall defines an aperture therein.

### Claim 9 (depends on 1)

The container of claim 1, wherein the basket is adapted such that it can be suspended in the tub from the tub sidewall.

### Claim 10 (depends on 1)

The container of claim 1, wherein the basket further comprises a tab, the tab adapted to be positioned such that it extends outwardly from the basket sidewall.

### Claim 11 (depends on 1)

The container of claim 1, wherein the container encloses a film stack, the film stack disposed between the base and the filler piece.

### Claim 12 (depends on 11)

The container of claim 11, wherein the film stack comprises a nanomaterial.

### Claim 13 (depends on 12)

The container of claim 12, wherein the nanomaterial comprises graphene.

### Claim 14 (depends on 12)

The container of claim 12, wherein the nanomaterial is at least partially covered by a polymer coating.

### Claim 15 (depends on 14)

The container of claim 14, wherein the polymer coating is operative to be stripped by acetone.

### Claim 16 (depends on 14)

The container of claim 14, wherein the polymer coating comprises poly(methyl methacrylate).

### Claim 17 (depends on 11)

The container of claim 11, wherein the film stack floats when placed in the liquid.

### Claim 18 (depends on 11)

The container of claim 11, further comprising a cover sheet, the cover sheet disposed between the film stack and the filler piece.

### Claim 19 (depends on 18)

The container of claim 18, wherein the cover sheet comprises a fabric.

### Claim 20 (depends on 11)

The container of claim 11, wherein the film stack is substantially held immobile against the base.
