Abstract

The invention provides a unique system for providing partition dividers in stowing units (e.g. shelving, trays, and containers). This is accomplished by providing a stowing unit with an adhesive viscoelastomeric thermoset polymer which adhesively restrains a free-standing divider adapted to be removed and repositioned at any desired positon to fit a user's stowing needs. The adhesive polymer is also cohesive and releases both the divider and any stowed items in contact with the polymer via the application of a counteracting removal force sufficient to overcome the adhesive attraction of the polymer. Accordingly, dividers fixedly attached to conventional sectionalized containers are suitably replaced herein by the repositionable divider combination.

Claims (41)

1. A sectionalized containment combination comprising a support member, an adhesive and cohesive viscoelastomeric thermoset polymer disposed upon the support member, and a divider member adhesively disposed upon the polymer, wherein the divider member can be repositioned to adjust the sectionalized containment combination to a desired configuration for stowage use.

2. The sectionalized containment combination of claim 1 , wherein the divider member is a free-standing divider member.

3. The sectionalized containment combination of claim 1 , further comprising releasability properties such that the divider member can be removed upon application of a sufficient removal force without detachment of the polymer from the support member.

4. The sectionalized containment combination of claim 1 , wherein the polymer is derived from a thermosetting reaction media comprising:

a) about 2 wt % to about 10 wt % diisocyanate prepolymer;

b) about 35 wt % to about 75 wt % polyols; and

c) about 10 wt % to about 60 wt % plasticizer;

wherein the polyols comprise about 1 wt % to about 65 wt % straight chain diol by weight of the reaction media and about 3 wt % to about 50 wt % crosslinking polyol by weight of the reaction media; and

wherein the plasticizer comprises about 10 wt % to less than 50 wt % epoxidized triglyceride plasticizer by weight of the reaction media and 0 wt % to about 40 wt % ester plasticizer by weight of the reaction media.

5. The sectionalized containment combination of claim 4 , wherein the plasticizer comprises about 10 wt % to less than 45 wt % epoxidized triglyceride plasticizer by weight of the reaction media.

6. The sectionalized containment combination of claim 4 , wherein the diisocyanate prepolymer is selected from the group consisting of aromatic diisocyanates and aliphatic diisocyanates.

7. The sectionalized containment combination of claim 4 , wherein the crosslinking polyol comprises triol.

8. The sectionalized containment combination of claim 4 , further comprising a straight chain diol to crosslinking polyol weight ratio of about 1:3 to about 3:1.

9. The sectionalized containment combination of claim 4 , wherein the ester plasticizer comprises a molecular weight of less than about 750.

10. The sectionalized containment combination of claim 1 , wherein the polymer comprises an adhesiveness of about 100 gf/cm 2 to about 2,500 gf/cm 2 .

11. The sectionalized containment combination of claim 1 , wherein the support member comprises a substantially flat structure substantially free from any other confining structure.

12. The sectionalized containment combination of claim 1 , wherein an item disposed upon the sectionalized containment combination is substantially prevented from movement thereupon.

13. The sectionalized containment combination of claim 1 , further comprising cleansability and reusability properties, wherein a contaminant adhered to the polymer can be removed therefrom via washing with water, and wherein an adhesiveness of the polymer substantially returns to its original state upon fully drying.

14. The sectionalized containment combination of claim 1 , further comprising antimicrobial properties.

15. A method of providing a sectionalized containment combination for segregating items and stabilizing the items against movement comprising:

a) providing a support member;

b) disposing an adhesive and cohesive viscoelastomeric thermoset polymer upon a surface of the support member; and

c) adhesively engaging a repositionable divider member onto the polymer at a desired partitioning position.

16. The method of claim 15 wherein the polymer is prefabricated prior to disposing the polymer upon the support member.

17. The method of claim 15 wherein the polymer has been cured in situ upon the support member.

18. The method of claim 15 wherein the polymer is derived from a thermosetting reaction media comprising:

a) about 2 wt % to about 10 wt % diisocyanate prepolymer;

b) about 35 wt % to about 75 wt % polyols; and

c) about 10 wt % to about 60 wt % plasticizer;

wherein the polyols comprise about 1 wt % to about 65 wt % straight chain diol by weight of the reaction media and about 3 wt % to about 50 wt % crosslinking polyol by weight of the reaction media; and

wherein the plasticizer comprises about 10 wt % to less than 50 wt % epoxidized triglyceride plasticizer by weight of the reaction media and 0 wt % to about 40 wt % ester plasticizer by weight of the reaction media.

19. A method for adjusting a sectionalized containment combination for segregating items comprising:

a) providing a sectionalized containment combination comprising a support member, an adhesive and cohesive viscoelastomeric thermoset polymer and a free-standing divider member, wherein the polymer is disposed upon a surface of the support member, and wherein the divider member is disposed upon the polymer;

b) removing the divider member from the sectionalized containment combination by exerting a sufficient removal force to counteract an adhesiveness of the polymer; and

c) disposing the divider member onto the polymer in a different configuration position.

20. The method of claim 19 wherein the polymer is derived from a thermosetting reaction media comprising:

a) about 2 wt % to about 10 wt % diisocyanate prepolymer;

b) about 35 wt % to about 75 wt % polyols; and

c) about 10 wt % to about 60 wt % plasticizer;

wherein the polyols comprise about 1 wt % to about 65 wt % straight chain diol by weight of the reaction media and about 3 wt % to about 50 wt % crosslinking polyol by weight of the reaction media; and

wherein the plasticizer comprises about 10 wt % to less than 50 wt % epoxidized triglyceride plasticizer by weight of the reaction media and 0 wt % to about 40 wt % ester plasticizer by weight of the reaction media.
