## Abstract

A containment system with a vented insert for a fitment is disclosed. The vented insert includes generally a conduit having an inner and opposite outer end with a valve in the conduit movable to a closed position by liquid. The outer end of the conduit includes a liquid impermeable membrane.

## Claims

### Claim 1

A vented insert for a liquid pouch fitment, comprising:
a conduit having an inner and opposite outer end;
a valve in the conduit movable to a closed position by liquid; and
a liquid impermeable membrane at the outer end of the conduit.

### Claim 2 (depends on 1)

The vented insert of claim 1 further comprising a generally tapered body having an inner and opposite outer end, the generally tapered body housing the conduit.

### Claim 3 (depends on 2)

The vented insert of claim 2 further comprising one or more barbs extending outward from the tapered body between the inner and outer ends.

### Claim 4 (depends on 1)

The vented insert of claim 1 wherein the valve includes a chamber in the conduit with an opening in communication with the outer end selectively closed by a float.

### Claim 5 (depends on 4)

The vented insert of claim 4 wherein the valve includes a closed position wherein the float is positioned in covering relation over the opening in the conduit when the chamber fills with liquid.

### Claim 6 (depends on 4)

The vented insert of claim 4 wherein the valve includes an open position wherein the float is positioned generally between the opening and the inner end.

### Claim 7 (depends on 1)

The vented insert of claim 1 further comprising a body having an outer end housing the outer end of the conduit and an elongated portion extending from the outer end to an inner end housing the inner end of the conduit.

### Claim 8 (depends on 7)

The vented insert of claim 7 wherein the elongated portion includes a protuberated portion adapted to prevent removal of the insert from the fitment.

### Claim 9 (depends on 1)

The vented insert of claim 1 wherein the liquid impermeable membrane is positioned in the outer end of the housing.

### Claim 10

A vented insert for a liquid pouch fitment, comprising:
a generally tapered body having an inner and opposite outer end;
a conduit through the body generally between the inner and outer ends;
a valve in the conduit between the inner and outer ends, the valve movable between open and closed positions by liquid entering the conduit; and
a liquid impermeable membrane at the outer end of the conduit.

### Claim 11 (depends on 10)

The vented insert of claim 10 in combination with a liquid pouch fitment.

### Claim 12 (depends on 10)

The vented insert of claim 10 wherein the liquid impermeable membrane comprises expanded polytetrafluoroethylene (ePTFE).

### Claim 13 (depends on 10)

The vented insert of claim 10 wherein the tapered body includes a protuberated portion generally at the inner end.

### Claim 14 (depends on 10)

The vented insert of claim 10 wherein the valve has closed position wherein a buoyant member is moved into blocking engagement with the conduit by liquid passing through the inner end.

### Claim 15 (depends on 10)

The vented insert of claim 10 wherein the valve has an open position wherein a buoyant member is separated from blocking engagement with the conduit.

### Claim 16

A product containment system comprising:
a container configured to hold a liquid product;
a fitment coupled to the container;
a vented insert in the fitment having a conduit with an inner and opposite outer end;
a valve in the conduit movable to a closed position by liquid entering the conduit; and
a liquid impermeable membrane at the outer end of the conduit.

### Claim 17 (depends on 16)

The product containment system of claim 16 wherein the liquid impermeable membrane is outside the container.

### Claim 18 (depends on 16)

The product containment system of claim 16 wherein the fitment includes a body having a body passage into the container.

### Claim 19 (depends on 18)

The product containment system of claim 18 wherein the vented insert includes a protuberated portion generally near the inner end in locking engagement with the body passage.

### Claim 20 (depends on 16)

The product containment system of claim 16 wherein the valve is inside the container.

### Claim 21 (depends on 16)

The product containment system of claim 16 wherein a buoyant member in the valve has a closed position in response to liquid entering the conduit.

### Claim 22 (depends on 16)

The product containment system of claim 16 wherein a buoyant member in the valve has an open position in response to liquid being absent from the conduit.
