Abstract

Systems and methods for a flexible container for transport and storage of a working material are described herein. The material can be a viscous or liquid material when dispensed. The flexible container can be configured to move between a first shape and a second shape. The first shape can allow for efficient transport of the flexible container while the second shape can allow for the flexible container to couple to a dispenser. In certain examples, the flexible container can be cooled for transport and heated for dispensing.

First claim

What is claimed is:

1. A flexible container comprising:
a substantially planar container body comprising a first side and a second side, wherein the container body is configured to rest in a first position and a second position, wherein the container body in the first position is in a substantially planar shape, and wherein the container body in the second position is in a substantially tubular shape;
a thermal element disposed in the container body;
a port disposed at the first side of the container body and substantially centered across a width of the container body such that the port is configured to receive a nozzle; and
a check valve disposed within the port and configured to allow material to flow into the container body and prevent the material from flowing out of the container body,
wherein:
the port and check valve are flush with the first side to allow planar stacking of the container body in the first position, and
the thermal element is configured to be operated when the container body is in contact with another container body.

2. A method for processing a material, the method comprising:
disposing the flexible container of claim 1 between at least two substantially parallel surfaces;
coupling the port of the flexible container to a material fill mechanism;
providing the material into the flexible container with the material fill mechanism; and
freezing the material within the flexible container.

3. The method of claim 2 , further comprising:
thawing the material;
rolling the flexible container into the substantially tubular shape; and
coupling the flexible container to a dispenser.

4. The method of claim 3 , wherein the flexible container is configured to fully roll into the substantially tubular shape upon receiving a first force.

5. The method of claim 3 , wherein the coupling the flexible container to the dispenser comprises puncturing the flexible container with the dispenser.

6. The method of claim 3 , wherein the coupling the flexible container to the dispenser comprises receiving the nozzle of the dispenser with the check valve of the flexible container.

7. The method of claim 3 , further comprising:
flowing the material into the dispenser; and
extruding the material onto a first surface with the dispenser.

8. The method of claim 3 , wherein the freezing the material and the thawing the material are through operation of the thermal element within the flexible container, wherein method further comprises operating the thermal element when the flexible container is in contact with another flexible container.

9. The method of claim 3 , wherein the dispenser is a 3M 600A or Semco 250-A applicator gun.

10. The method of claim 2 , wherein the material is an aerospace fluid.

11. The method of claim 2 , further comprising:
coupling the first side comprising a first flexible portion and the second side comprising a second flexible portion to form the flexible container.

12. The flexible container of claim 1 , wherein the material is an aerospace fluid.

13. The flexible container of claim 12 , wherein the first side is tensioned when the container body is in the first position.

14. The flexible container of claim 1 , wherein the port is configured to couple to an inlet of a dispenser.

15. The flexible container of claim 14 , wherein the dispenser is a 3M 600A or Semco 250-A applicator gun.

16. The flexible container of claim 1 , wherein the thermal element is operated in response to conduction between the container bodies due to the contact.

17. A flexible container comprising:
a substantially planar container body comprising a first side and a second side, wherein the container body is configured to rest in a first position and a second position, wherein the container body in the first position is in a substantially planar shape, and wherein the container body in the second position is in a substantially tubular shape;
a port disposed on the container body and configured to receive a nozzle;
a check valve disposed within the port and configured to allow material to flow into the container body and prevent the material from flowing out of the container body, wherein the port and check valve are flush with the container body to allow planar stacking of the container body in the first position;
a thermal element disposed in the container body, wherein the thermal element is configured to be operated when the container body is in contact with another container body; and
a controller configured to control a temperature of the thermal element, disposed on the thermal element.

18. The flexible container of claim 17 , wherein the thermal element is operated in response to conduction between the container bodies due to the contact.

19. The flexible container of claim 17 , wherein the first side comprises an outer layer and an inner layer, and wherein the thermal element is disposed between the outer layer and the inner layer.

20. The flexible container of claim 19 , wherein a thermal conductivity of the inner layer is greater than a thermal conductivity of the outer layer.
