The present invention includes processes and resulting structures for producing moisture absorbing desiccant entrained polymers. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. To achieve certain results in the hardened end product, such as rigidity and durability, the polymer normally acts as a moisture barrier in a solidified state, both before and after melting. A desiccating agent is blended into the polymer so that the desiccating agent is distributed within the polymer. A channeling agent is also blended into the polymer so that it is distributed within the polymer. Together, the polymer, desiccating agent and channeling agent create a blended mixture. The mixture is solidified so that the channeling agent forms passages in the mixture through which moisture is communicable to desiccating agent that is entrained within the mixture. The solidified mixture may be used to form plug type inserts and liners for closed containers, or it may be used for producing laminated sheeting employed as package wrap. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE PRESENT INVENTION As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms.
The figures are not necessarily to scale, some features may be exaggerated to show details of particular components.
Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.
Certain terminology will be used in the following description for convenience and reference only and should not be considered limiting.
For example, the words "rightwardly", "leftwardly", "upwardly" and "downwardly" refer to directions in the drawings to which reference is made.
The words "inwardly" and "outwardly" refer to directions toward and away from, respectively, the geometric center of the structure being referred to.
This terminology includes these words, specifically mentioned derivatives thereof, and words of similar import.
Furthermore, elements may be recited as being "coupled"; this terminology's use anticipates elements being connected together in such a way that there may be other components interstitially located between the specified elements, and that the elements may be connected in fixed or movable relation, one to the other.
Still further, some structural relationships or orientations may be designated with the word "substantially".
In those cases, it is meant that the relationship or orientation is as described, with allowances for variations that do not effect the operation or cooperation of the so described component or components.
Referring to FIG.
1 of the accompanying drawings, an insert constructed from a desiccant entrained polymer 20 is illustrated.
For purposes of this disclosure of the present invention, the words "entrain" and "contain" have been used interchangeably when referring to the inclusion of a desiccating agent 30 in a polymer 25 matrix
