Self-sealing valve and fluid fillable article including such a valve

Claim 2

A valve for use in a fluid fillable article, the valve comprising: (a) first and second planar members positioned to have their surfaces in contact, the surfaces having a major bonded portion and an minor unbonded portion of elongated shape therebetween; (b) a first opening through the first member for communicating between the unbonded portion and the outside of a fluid fillable article; and (c) a second opening for communicating between the inside of a fluid fillable article and the unbonded portion, the second opening being offset from the position of the first opening; the first and second openings and the unbonded portion defining a normally open channel suitable for receiving an elongated filling means and at least the second member having sufficient flexibility to close the channel responsive to pressure from within a fluid fillable article which contains the valve.

Claim 3

The valve of claim 1 wherein the second opening is positioned along the edge of the valve.

Claim 4

The valve of claim 1 wherein the second opening is in the second member.

Claim 5

The valve of claim 1 wherein the members are formed from a material comprising a silicone rubber and wherein bonded portions are bonded by heat curing.

Claim 6

The valve of claim 1 wherein the unbonded portion has a non-linear shape.

Claim 7

The valve of claim 1 wherein the first member is bonded to a planar valve support, the valve support having an opening positioned to coincide with the opening in the first member.

Claim 8

The valve of claim 6 wherein at least the first member and the valve support are formed from a material comprising a silicone rubber and wherein bonding is by heat curing.

Claim 9

The valve of claim 6 wherein the valve support is bonded to a fluid fillable article so as to close an aperture therein and to position the valve on the inside of the article.

Claim 10

The valve of claim 8 wherein at least the valve support and the fluid article are formed from a material comprising a silicone rubber and wherein bonding is by heat curing.

Claim 11

The valve of claim 8 wherein the fluid fillable article is a mammary prosthesis.

Claim 12

The valve of claim 1 wherein the first planar member is bonded to a fluid fillable article so as to close an aperture therein and to position the valve on the inside of the inflatable article.

Claim 13

The valve of claim 11 wherein bonding between the first planar member and the fluid fillable article is by an adhesive.

Claim 14

The valve of claim 11 wherein the inflatable article is a mammary prosthesis.

Claim 15

A self-sealing fluid fillable article comprising a fluid fillable member and a valve, the valve comprising: (a) first and second planar flexible members positioned to have their surfaces in contact, the surfaces having a major bonded portion and an minor unbonded portion of extended shape therebetween; (b) a first opening through the first member for communicating between the unbonded portion and the outside of the fluid fillable article; and (c) a second opening for communicating between the inside of the fluid fillable article and the unbonded portion, the second opening being offset from the position of the first opening, the first and second openings and the unbonded portion defining a normally open channel for receiving an elongated filling means; at least the second member having sufficient flexibility to close the channel responsive to pressure from within the fluid fillable article.

Claim 16

A self-sealing fluid fillable article comprising a fluid fillable member and a valve, the valve comprising: (a) first and second planar flexible members positioned to have their surfaces in contact, the surfaces having a major bonded portion and an minor unbonded portion of extended shape therebetween; (b) a first opening through the first member for communicating between the unbonded portion and the outside of the fluid fillable article; and (c) a second opening for communicating between the inside of the fluid fillable article and the unbonded portion, the second opening being offset from the position of the first opening, the first and second openings and the unbonded portion defining a normally open channel for receiving an elongated filling means; at least the second member having sufficient flexibility to close the channel responsive to pressure from within the fluid fillable article.

Claim 17

The self-sealing fluid fillable article of claim 14 wherein at least the first planar member and the fluid fillable member are formed from a material comprising a silicone rubber.

Claim 18

The self-sealing fluid fillable article of claim 14 further including a planar valve support member bonded on one side to the first planar member and on the other side to the fluid fillable member, the valve support member having an opening positioned to coincide with the opening in the first member.

Claim 19

The self-sealing fluid fillable article of claim 14 wherein the fluid fillable member is a mammary prosthesis.
