  • Patent number: 11124596
    Abstract: The invention provides a unique thermoset viscoelastomeric reaction product and a container combination comprised of the supportive base equipped with a thermoset viscoelastomer reaction product possessing unexpectedly superior adhesive and cohesive efficacy rendering it especially useful as an adhesive insert in a container combination. The thermoset insert bonds to any suitable supportive structure. The unique viscoelastomeric reaction product inserts adhesively immobilize items placed thereupon and adhesively or permanently bonds to most conventional containers. The tenacious cohesive and adhesive features of the insert allows for inverted stowage of stowed items. Due to the confining adhesive and cohesive attributes of the insert, structural supports of a flexible or solid base without a conventional confining structure provide a unique container combination for the stowed items.

  • Patent number: 11046482
    Abstract: A lighting apparatus is provided including at least one light adhered to a releasably adhesive viscoelastic polymer component. The light may be disposed upon, or at least partially disposed within, the viscoelastic polymer. The viscoelastic polymer component has a unique adhesiveness and cohesiveness, which allows the lighting apparatus to be releasably adhered to a variety of objects. Upon release of the lighting apparatus from an object, the viscoelastic polymer component leaves substantially no residue remaining on the object. The lighting apparatus can then be re-adhered to the object with substantially the same degree of adhesiveness as when originally adhered. In addition, a variety of articles can be adhered to the lighting apparatus, as desired.
