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 vertical wall section, a bottom portion, and a dimple, the dimple having a circular base and an inner portion converging to a hole extending into the second outer wall, the hole being sealed;
a sealed vacuum cavity forming an insulated double wall structure between the first inner wall and the second outer wall; and
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;
wherein the vertical wall section defines an inner wall for receiving the bottom portion and comprises a bottom-most surface, wherein the weld is formed between the cap and the bottom-most surface.
2. The insulating container of claim 1 wherein the cap supports the container on a surface.
3. The insulating container of claim 1 wherein the cap receives a weight for damping sound when the container is placed on a surface.
4. The insulating container of claim 1 wherein the dimple is located in the bottom portion and wherein the hole of the dimple is sealed by a resin.
5. The insulating container of claim 4 wherein the bottom portion defines a center and the dimple is located at the center.
6. The insulating container of claim 1 wherein the dimple resembles a dome shape.
7. The insulating container of claim 1 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, the second outer wall, and the cap 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 vertical wall section, a bottom portion, and a dimple, forming the dimple in the second outer wall and forming the dimple with a circular base and an inner portion converging to a hole extending through the second outer wall;
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, wherein the vertical wall section comprises an inner wall and a bottom-most surface; and
providing a cap to cover the dimple, welding the cap to the bottom-most surface of the vertical wall section to form a weld, and polishing the weld, such that the weld is not visually apparent to a user.
10. The method of claim 9 further comprising configuring the cap to support the container on a surface.
11. The method of claim 9 further comprising locating the dimple on the bottom portion.
12. The method of claim 11 wherein the bottom portion defines a center and locating the dimple at the center.
13. The method of claim 9 further comprising providing the cap with a weight for damping sound when the container is placed on a surface.
14. The method of claim 9 further comprising forming the dimple into a dome shape.
15. The method of claim 9 further comprising forming the first inner wall, the second outer wall, and the cap of one of titanium or stainless steel.
16. The method of claim 9 further comprising forming the weld below the sealed vacuum cavity.
