Abstract
Extending into the open end of a cylindrical container is the stem of an earplug inserter that has an enlarged portion outside of the container forming a shoulder spaced from the open end of the container. Enclosing the stem between it and the encircling side wall of the container is a thin sound-attenuating mat of fibers, the marginal portion of which extends out of the container and flares outwardly across the inserter shoulder. This mat forms an earplug that is removable with the inserter from the container to permit insertion of the earplug in an ear by means of the inserter, which is then withdrawn from the plug. The earplug is made by placing a flat fibrous mat against the open end of the container and then pushing it into the container by means of the inserter stem.

An earplug package comprising a cylindrical container open at at least one end, an earplug inserter having a stem extending axially into said open end of the container and spaced from the side wall of the container, the inserter having an enlarged portion outside of the container forming a shoulder extending laterally away from said stem and spaced from said open end of the container, and a thin sound-attenuating mat of fibers enclosing said stem and disposed between it and the encircling side wall of the container with the free end of said stem pressed against the central portion of the mat, the marginal portion of said mat extending out of the container and flaring outwardly across said shoulder, the mat forming an earplug removable with said inserter from the container to permit insertion of the earplug in an ear by means of the inserter.
The method of making an earplug package, comprising centering a thin fibrous mat over the open end of a cylindrical container, pressing the stem of an earplug inserter against the center of the mat and inserting the stem axially into the container to push the mat into it and cause the mat to enclose the stem, stopping insertion of the inserter into the container while the marginal portion of the mat remains outside of the container in a flared-out position between a shoulder on said inserter and the adjacent end of the container, whereby the mat forms an earplug that can be removed with the inserter from the container to permit insertion of the earplug in an ear by means of the inserter.
