## Abstract

A sorbent container includes a permeable plastic container, a permeable membrane, and a sorbent. The permeable plastic container includes a sidewall and an endwall, the sidewall defining an opening opposite the endwall. The permeable membrane is fused to the sidewall to cover the opening. A fused junction is formed between the sidewall and the permeable membrane. The sorbent is disposed within the plastic container.

## Claims

### Claim 1

A sorbent canister comprising:
a permeable plastic container comprising a sidewall and an endwall, the sidewall defining an opening opposite the endwall;
a permeable membrane fused to the sidewall to cover the opening;
a fused junction between the permeable membrane and the sidewall; and
a sorbent within the plastic container.

### Claim 2 (depends on 1)

The sorbent canister of claim 1, wherein the permeable plastic container is injection-molded.

### Claim 3 (depends on 1)

The sorbent canister of claim 1, wherein the endwall is transparent.

### Claim 4 (depends on 3)

The sorbent canister of claim 3, wherein the sidewall is opaque.

### Claim 5 (depends on 1)

The sorbent canister of claim 1, wherein the endwall is thinner than the sidewall.

### Claim 6 (depends on 1)

The sorbent canister of claim 1, further comprising a beveled surface formed at the fused junction.

### Claim 7 (depends on 1)

The sorbent canister of claim 1, further comprising one or more ribs extending to the sidewall.

### Claim 8 (depends on 1)

The sorbent canister of claim 1, wherein the sorbent is a granular sorbent.

### Claim 9 (depends on 1)

The sorbent canister of claim 1, wherein the sorbent is a liquid sorbent.

### Claim 10 (depends on 1)

The sorbent canister of claim 1, wherein the container has a first permeability and the permeable membrane has a second permeability, different from the first permeability.

### Claim 11 (depends on 1)

The sorbent canister of claim 1, wherein the sorbent is one of a cream and a gel.

### Claim 12

A method of forming a sorbent capsule comprising:
providing a permeable plastic container comprising a sidewall and an endwall, the sidewall defining an opening opposite the endwall;
filling a portion of the permeable plastic container with a sorbent through the opening;
providing a permeable membrane; and
fusing the permeable membrane to the sidewall to cover the opening and retain the sorbent in the container.

### Claim 13 (depends on 12)

The method of claim 12, wherein the fusing step creates a fused junction and further comprising beveling the fused junction.

### Claim 14 (depends on 12)

The method of claim 12, wherein the endwall has a first thickness and the sidewall has a second thickness, different from the first thickness.

### Claim 15 (depends on 12)

The method of claim 12, wherein the container has a first permeability and the permeability membrane has a second permeability different from the first permeability.

### Claim 16 (depends on 12)

The method of claim 12, wherein the endwall of the container has a first thickness and the sidewall of the container has a second thickness different from the first thickness.

### Claim 17 (depends on 12)

The method of claim 12, wherein the endwall of the container is transparent.

### Claim 18 (depends on 12)

The method of claim 12, wherein the sorbent is a granular sorbent.

### Claim 19 (depends on 12)

The method of claim 12, wherein the sorbent is a liquid sorbent.

### Claim 20 (depends on 12)

The method of claim 12, wherein the sorbent is one of a cream and a gel.
