COMPOSITION CONTAINER WITH A BRACKET INTERFACING PROTRUSION

1 . A composition container comprising:

a reservoir to contain a composition;

a protrusion extending from a surface of the reservoir to interface with a retaining bracket, wherein the protrusion comprises:

a number of vertical ribs extending from a surface of the protrusion; and

a number of horizontal rings extending from the surface of the protrusion.

2 . The composition container of claim 1 , wherein the composition is a foaming fluid.

3 . The composition container of claim 1 , wherein the number of vertical ribs and the number of horizontal rings engage with internal threading on the retaining bracket.

4 . The composition container of claim 1 , wherein the number of horizontal rings are positioned a distance away from the surface of the reservoir greater than a length of threading of the retaining bracket.

5 . The composition container of claim 4 , wherein the number of horizontal rings, when below the threading of the retaining bracket, allow the composition container to rotate within the retaining bracket.

6 . The composition container of claim 1 , wherein the protrusion is hollow.

7 . The composition container of claim 1 , wherein the container is an asymmetrical container.

8 . The composition container of claim 1 , wherein the protrusion is formed of a softer material than the retaining bracket.

9 . The composition container of claim 1 , wherein the protrusion is cylindrical.

10 . A composition containing system comprising:

a reservoir to contain a composition;

a bracket interface to retain the reservoir in a threaded retaining bracket, wherein the bracket interface comprises at least one horizontal ring and multiple vertical ribs to frictionally couple the reservoir to the threaded retaining bracket.

11 . The system of claim 10 , wherein the bracket interface is disposed on a protrusion extending below the reservoir.

12 . The system of claim 11 , wherein the multiple vertical ribs are radially disposed around the protrusion.

13 . The system of claim 10 , wherein the bracket interface facilitates a friction fit of the reservoir into the threaded retaining bracket.

14 . The system of claim 10 , wherein the bracket interface engages the threaded retaining bracket when a torsional force is applied.

15 . A composition container comprising:

a reservoir to contain a composition;

a dispensing device to dispense the composition from the reservoir onto an application surface; and

a protrusion extending from a surface of the reservoir to interface with, and retain the container to, a retaining bracket, wherein the protrusion comprises a number of radially-disposed vertical ribs extending from a surface of the protrusion and a number of circumferential rings extending from the surface of the protrusion to engage with threads of a threaded retaining bracket to secure the composition container to the threaded retaining bracket.

16 . The composition container of claim 15 , wherein the protrusion is deformable against threads of the threaded retaining bracket.

17 . The composition container of claim 15 , wherein the number of horizontal rings are positioned a distance away from the surface of the reservoir greater than the length of threading of the threaded retaining bracket.

18 . The composition container of claim 17 , wherein the number of horizontal rings, when below the threading of the retaining bracket, allow the composition container to rotate within the retaining bracket.

19 . The composition container of claim 15 , wherein the protrusion is hollow and is in fluid communication with the reservoir.

20 . The composition container of claim 15 , wherein the protrusion extends from a surface of the reservoir opposite the dispensing device.
