Beverage brewer

1. A beverage brewer for brewing material placed between upper and lower filter membrane surfaces comprising:

a showerhead forming a boundary for a pod chamber;

a pod carrier forming a boundary for said pod chamber; and

a main carrier mounting said showerhead having a contact surface to urge said filter membrane surfaces toward said pod carrier to crimp said filter membrane surfaces together along a periphery thereof,

wherein said main carrier contact surface is serrated.

2. A beverage brewer as described in claim 1 further including a seal connected with one of said showerhead and said pod carrier for sealing said pod chamber between said showerhead and said pod carrier.

3. A beverage brewer as described in claim 2 wherein said seal is surrounded by said main carrier contact surface.

4. A beverage brewer as described in claim 2 wherein said seal extends radially outwardly.

5. A beverage brewer as described in claim 2 wherein said seal extends radially inwardly.

6. A beverage brewer as described in claim 1 wherein said seal is connected with said showerhead.

7. A beverage brewer as described in claim 1 wherein said pod carrier has a serrated surface.

8. A beverage brewer as described in claim 1 wherein said showerhead is compliantly mounted with respect to said main carrier.

9. A beverage brewer having the capacity to brew a beverage from a free-form brewing material captured between upper and lower filter membrane surfaces, said beverage brewer comprising:

a showerhead forming a boundary for a pod chamber;

a pod carrier forming a boundary for said pod chamber;

a seal connected with one of said showerhead and said pod carrier for sealing said pod chamber between said shower head and said pod carrier; and

a main carrier mounting said showerhead and having a contact surface for urging said upper and lower filter membrane surfaces toward said pod carrier and thereby joining said filter membrane surfaces together outboard of said seal,

wherein at least one of said main carrier and said pod chamber is serrated and said filter membrane surfaces are crimped together by said main carrier contact surface.

10. A beverage brewer as described in claim 9 wherein adhesive bonding joins said filter membrane surfaces together.

11. A beverage brewer as described in claim 9 wherein said filter membrane surfaces are joined by heat bonding.

12. A beverage brewer as described in claim 9 wherein said seal is connected with said showerhead.

13. A beverage brewer as described in claim 9 wherein said main carrier contact surface is serrated.

14. A beverage brewer as described in claim 8 wherein said pod carrier has a serrated surface for contacting said filter membranes opposite said main carrier contact surface.

15. A beverage brewer as described in claim 9 wherein said showerhead is compliantly mounted with respect to said first body.
