Dispensing Tubs with Elastomer Inserted Lids and Bases

Abstract

An over-molded elastomer insert on the bottom surface of a plastic tub. The elastomer material has a higher friction coefficient than the usual plastic material used to make the tub. The elastomer pad is integrated to the surface of the tub which is in contact with the table top or flat surface on which it is placed. The bottom surface presents some areas filled by material with a higher coefficient of friction, they are less prone to sliding. An over-molded elastomer insert on the top surface of a plastic tub's lid or lid. The elastomer parts are integrated to the surface of the tub which is in contact with the bottom of another tub sitting on top of it when stacked. The top surface presents some areas filled by material with a higher coefficient of friction, this helps to improve the stability of tubs stacked one over the other.
