Abstract

The invention relates to a one-piece foam construct reversibly assembled by at least one binder, as well as the methods of making and assembling said one-piece foam construct. The construct is meant for use as a cleaning implement.

Claims (36)

1. A foam construct for use as a cleaning implement comprising:

A foam strip having at least a left portion and a right portion;

A middle portion disposed between said left portion and said right portion;

At least one cut on at least one of said left portion and said right portion;

a first binder and a second binder, wherein said second binder holds the foam strip in a rolled state and said first binder comprises a handle;

wherein said first binder has a first thickness and further comprises at least one stopper section having a second thickness, wherein said second thickness is thicker than said first thickness;

wherein said middle portion is secured in a compressed state;

wherein said first binder passes through a center of said middle portion such that the stopper section is on one side of the construct and the handle is on the other side of the construct, wherein the stopper prevents the first binder from pulling through the foam construct when it is in the rolled state; and

wherein said foam construct further comprises at least one additive, wherein said at least one additive is an antibacterial agent.

2. The foam construct for use as a cleaning implement of claim 1 , wherein said foam construct further comprises at least a second additive.

3. The foam construct for use as a cleaning implement of claim 2 , wherein said at least second additive is chosen from the group consisting of: soaps, detergents, skin care agents, hydrocolloid absorptive agents, medicaments, proteins, enzymes, nucleic acids, vitamins, hemostatic agents, antibacterial agents, antifungal agents, surfactants, pH buffers, rubber particles, disinfecting and sterilizing agents, thermal phase change particles, and combinations thereof.

4. The foam construct for use as a cleaning implement of claim 2 , wherein said foam construct further comprises at least one component.

5. The foam construct for use as a cleaning implement of claim 4 , wherein said at least one component is chosen from the group consisting of:

dispersants, surfactants, foaming and blowing agents, superabsorbent polymers, polymer initiators, dyes, cross-linking agents, catalysts, and polymer-chain size modifiers.

6. The foam construct for use as a cleaning implement of claim 1 , wherein said at least one cut is a plurality of cuts applied to both said left portion and said right portion.

7. The foam construct for use as a cleaning implement of claim 1 , wherein said second binder is reversibly applied.

8. The foam construct for use as a cleaning implement of claim 1 , wherein said first and second binders are selected from the group consisting of: ties, adhesives, and fasteners.

9. The foam construct for use as a cleaning implement of claim 1 , wherein when the foam strip is in a rolled state and the middle portion is in a compressed state, a density gradient is formed by a dense core and a less dense outer shell comprising projections of the left portion and the right portion of the foam strip.

10. A method of making a foam construct for use as a cleaning implement comprising the steps of:

Providing a foam strip having a left portion, a right portion, and a middle portion disposed between said left portion and said right portion;

Providing at least one cut in at least one of said left portion and said right portion;

Providing a first binder that passes through a center of said middle portion such that a stopper section of the first binder is on one side of the foam construct and a handle section of the first binder is on the other side of the foam construct;

Compressing said foam strip such that it encloses the first binder;

Securing said foam strip on said middle portion in a compressed state such that the stopper section is prevented from being pulled through the foam construct by the handle section;

Adding at least one component, wherein said component is a superabsorbent polymer capable of absorbing at least 15 times its own weight in aqueous fluid; and

Adding a blowing agent.

11. The method of making a foam construct for use as a cleaning implement of claim 10 , wherein the step of providing a the foam strip further comprises the step of:

admixing a prepolymer, water, and an additive.

12. The method of claim 11 , wherein said admixed additive is chosen from the group consisting of: soaps, detergents, skin care agents, hydrocolloid absorptive agents, medicaments, proteins, enzymes, nucleic acids, vitamins, hemostatic agents, antifungal agents, pH buffers, rubber particles, disinfecting and sterilizing agents, thermal phase change particles, and combinations thereof.

13. The method of making a foam construct for use as a cleaning implement of claim 10 , wherein the step of compressing the foam strip further comprises the step of:

Rolling said foam strip.

14. The method of making a foam construct for use as a cleaning implement of claim 10 , wherein the step of securing said foam strip in a compressed state comprises the step of:

Applying a second binder to said foam strip on said middle portion.

15. The method of claim 10 , further comprising the step of adding at least a second component.

16. The method of claim 15 , further comprising the step of adding at least a second component selected from the group consisting of:

dispersants, surfactants, foaming and blowing agents, superabsorbent polymers, polymer initiators, dyes, cross-linking agents, catalysts, and polymer-chain size modifiers.
