Earplug
First Claim
1. An earplug, comprising:
- a tip for use in forward and lateral sealing, which is formed to define a rearward recessed cavity; and
a stem, including;
a user graspable elongate portion configured with a stiffness in a first direction that is greater than a stiffness in a second direction, which is transverse to the first direction, anda member, disposed at a forward end of the elongate portion and configured to be insertable into the cavity, wherein the member includes a surface to be adhered to an interior facing surface of the cavity and on which a channel is defined to allow for outflow from the cavity, and the member is formed with a shape to complement that of the cavity to axially and circumferentially align the tip and the stem.

22. A method of assembling an earplug, the method comprising:
-
forming a tip for use in forward and lateral sealing; boring a cavity into the tip from a rear face thereof; forming a stem with a biaxial stiffness including an elongate portion, and a member, disposed at a forward end of the elongate portion and configured to be insertable into the cavity; defining a channel along a surface of the member; aligning the member with the cavity; and adhering the surface of the member to an interior facing surface of the cavity with outflow from the cavity being urged along the channel.
