ABSTRACT:
The present invention provides a method of producing a protective device that is adapted for use with a container in order to inhibit ingress of unwanted materials through a handhold opening in a wall of the container. The method includes a first step of advancing a first strip of material in a longitudinal direction from an upstream location to a downstream location. As this first strip of material is advanced, it is longitudinally scored after which a second strip of material is secured to the first strip of material such that the second strip is sealed around a discrete consecutive portion of the scoring. Thereafter, an adhesive material is applied to a side surface of the first strip opposite the second strip. The joined first and second strips are then cut into individual units with portions of the first and second strips in each unit being sealed completely around the periphery thereof. The method can include further steps of applying a deadening material to the adhesive material on the side surface of the first strip opposite the second strip. Moreover, the step of scoring the first strip may be accomplished by continuously scoring the first strip as it is advanced in the downstream direction. This step of scoring may also be accomplished by scoring the first strip with a plurality of parallel, spaced-apart longitudinally extending score lines. The step of securing the second strip to the first strip may be accomplished by fusing the first and second strips together.
