## Abstract

An ice bag is described having a bladder formed with an opening, a threaded receiver coupled to the bladder at the opening, a threaded cap having a first portion formed of a rigid material and a second portion formed of an overmold material, the second portion providing a seal between the receiver and cap with the cap threaded into the receiver.

## Claims

### Claim 1

An ice bag comprising;
a bladder formed with an opening;
a threaded receiver coupled to said bladder at said opening;
a threaded cap having a first portion formed of a rigid material and a second portion formed of an overmold material, said second portion providing a seal between said receiver and cap with said cap threaded into said receiver.

### Claim 2 (depends on 1)

An ice bag as recited in claim 1 wherein said receiver has a first portion formed of a rigid material and a second portion formed of an overmold material, said second portion providing a seal between said receiver and bladder with said bladder coupled to said receiver.

### Claim 3 (depends on 1)

An ice bag as recited in claim 1 wherein said first portion of said cap comprises a hollow cylindrical portion and a flange and wherein said overmold material overlays a surface of said flange.

### Claim 4 (depends on 3)

An ice bag as recited in claim 3 wherein said flange surface is formed with a recess to increase bond strength between said overmold material and said flange.

### Claim 5 (depends on 3)

An ice bag as recited in claim 3 wherein said flange extends to lip formed with a plurality of cutouts and said overmold material overlays a surface of said lip and establishes a plurality of grips for said cap within said cutouts.

### Claim 6 (depends on 1)

An ice bag as recited in claim 1 wherein said overmold material is a thermoplastic elastomer.

### Claim 7 (depends on 1)

An ice bag as recited in claim 1 wherein said rigid material is a plastic.

### Claim 8

An ice bag comprising;
a first threaded component and a second component, said first component having a first portion formed of a rigid material and a second portion formed of an elastomer fixedly attached to said first portion to provide a seal between said first and second components when said first and second components are coupled together.

### Claim 9 (depends on 8)

An ice bag as recited in claim 8 wherein said first threaded component is a receiver and said second component is a bladder.

### Claim 10 (depends on 8)

An ice bag as recited in claim 8 wherein said first threaded component is a receiver and said second component is a cap.

### Claim 11 (depends on 8)

An ice bag as recited in claim 8 wherein said first threaded component is a cap and said second component is a receiver.

### Claim 12 (depends on 8)

An ice bag as recited in claim 8 wherein said elastomer is fixedly attached to said first portion using an adhesive.

### Claim 13 (depends on 8)

An ice bag as recited in claim 8 wherein said elastomer is an overmold material.

### Claim 14 (depends on 8)

An ice bag as recited in claim 8 wherein said second component has a first portion formed of a rigid material and a second portion formed of a elastomer fixedly attached to said first portion of said second component to provide a seal between said second component and a third component when said second and third components are coupled together.

### Claim 15

A method for producing an ice bag comprising the steps of;
providing a bladder formed with an opening;
molding a first threaded component formed of a rigid material and a second component formed of a rigid material; and
overlying a thermoplastic elastomer material on a portion of said first threaded component in an overmolding process to produce a seal.

### Claim 16 (depends on 15)

The method as recited in claim 15 wherein said overmolding process is a multi-shot injection molding process.

### Claim 17 (depends on 15)

The method as recited in claim 15 wherein said overmolding process is an insert molding processes.

### Claim 18 (depends on 15)

The method as recited in claim 15 wherein said first threaded component is a cap.

### Claim 19 (depends on 15)

The method as recited in claim 15 wherein said first threaded component is a receiver.

### Claim 20 (depends on 19)

The method as recited in claim 19 wherein said step of overlying a thermoplastic elastomer material overlays a thermoplastic elastomer material on a receiver flange to produce a seal between said receiver and a cap.
