Container and method of forming a container
An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The second outer wall can include a second end configured to support the container on a surface. The second outer wall can include a dimple, and the dimple can include a circular base and an inner portion converging to an hole extending into the second outer wall. The hole can be sealed by a resin, and the circular base can be covered by disc formed of the material. Alternatively, a cap can cover the dimple, and a weld can connect the cap to the second outer wall. The container can also include a sealed vacuum cavity forming an insulated double-wall structure between the first inner wall and the second outer wall.
1. An insulating container comprising:
a first inner wall having a first end having an opening extending into an internal reservoir for receiving contents;
a second outer wall forming an outer shell of the container, the second outer wall comprising a bottom portion and a dimple located in the bottom portion, the dimple having a circular base and an inner portion converging to a hole extending into the second outer wall, the dimple resembling a dome shape, a cone, or a frustoconical shape, the hole being sealed; and
a sealed vacuum cavity forming an insulated double wall structure between the first inner wall and the second outer wall; and
a disc covering the circular base, wherein the disc is flush with a bottom surface of the bottom portion;
wherein the hole of the dimple is sealed by a resin; wherein the resin further seals the disc to the second outer wall.
2. The insulating container of claim 1 wherein the bottom portion defines a center and the dimple is located at the center.
3. The insulating container of claim 1 wherein the bottom portion defines a center and the dimple is located offset from the center.
4. The insulating container of claim 1 further comprising a cap covering the dimple and a weld connecting the cap to the second outer wall, wherein the weld is not visually apparent to a user.
5. The insulating container of claim 4 wherein the cap receives a weight for damping sound when the container is placed on a surface.
6. The insulating container of claim 4 wherein the second outer wall includes a vertical wall section which is configured to receive the bottom portion and the cap.
7. The insulating container of claim 4 wherein the second outer wall has a first thickness and the cap has a second thickness and wherein the second thickness is greater than the first thickness to dampen sound when the insulating container is placed onto a surface.
8. The insulating container of claim 1 wherein the first inner wall and the second outer wall are one of titanium or stainless steel.
9. A method of forming a container comprising:
forming a first inner wall with a first end having an opening extending into an internal reservoir for receiving contents;
forming a second outer wall into an outer shell for the container, the second outer wall comprising a bottom portion and a dimple, forming the dimple in the bottom portion of the second outer wall and forming the dimple with a circular base and an inner portion converging to an hole extending through the second outer wall, the dimple resembling a dome shape, a cone, or a frustoconical shape;
sealing the hole with a resin to form a sealed vacuum cavity as an insulated double wall structure between the first inner wall and the second outer wall;
covering the circular base with a disc; and
sealing the circular base to the second outer wall with the resin sealing the hole, wherein the disc is flush with a bottom surface of the bottom portion.
10. The method of claim 9 wherein the bottom portion defines a center and locating the dimple at the center.
11. The method of claim 9 wherein the bottom portion defines a center and locating the dimple offset from the center.
12. The method of claim 9 further comprising providing a cap to cover the dimple, welding the cap to the second outer wall to form a weld, and polishing the weld, such that the weld is not visually apparent to a user.
13. The method of claim 12 further comprising providing the second outer wall with a vertical wall section and securing the bottom portion and the cap to the vertical wall section.
14. The method of claim 12 further comprising providing the cap with a weight for damping sound when the container is placed on a surface.
15. The method of claim 9 further comprising forming the first inner wall and the second outer wall are one of titanium or stainless steel.
