A hearing protection device is provided including a sound attenuating element and a stem extending from the sound attenuating element, wherein the stem comprises multiple curved segments.

Hearing protector with curved segments

An earplug is provided and includes a tip for use in forward and lateral sealing, which is formed to define a rearward recessed cavity, and a stem. The stem includes 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, and a member, disposed at a forward end of the elongate portion and configured to be insertable into the cavity, the member including 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 being formed with a shape to complement that of the cavity to axially and circumferentially align the tip and the stem.

Earplug

The invention provides a stem for an earplug and an earplug incorporating the stem where the stem includes an attachment portion configured to receive and retain a sound attenuating element, the attachment portion extending substantially along an attachment axis, and a handle portion extending from the attachment portion substantially along a handle axis, where at least part of the handle axis is non-collinear with respect to the attachment axis.

Offset stem for earplug and earplug formed therewith

A multi-flanged earplug is provided, comprising a stem, a rounded flange positioned at a first end of the stem, and at least a second flange positioned between the first end portion of the stem and an opposing second end portion of the stem. In one embodiment, at least a portion of the first flange has a shape that is generally is generally convex with respect to the tip of the first end portion of the stem, while at least a portion of the second flange has a shape that is generally concave with respect to the tip of the first end portion of the stem. In another embodiment, an outer circumference portion of the second flange has an increased thickness relative to an inner, annular portion of the second flange. In another embodiment, an outer circumference portion of the second flange is provided with a protruding ridge.

Earplug stem

A hearing protection device is provided including a stem, a protrusion formed on the stem, an articulation point formed on the stem, and a sound attenuating element including a cavity, where the protrusion is disposed in locking engagement within the cavity to releasably attach the stem to the sound attenuating element, and where the stem is configured to at least partially articulate about the articulation point.

Earplug with articulating stem and locking features

A mold for forming a foam earplug including a lower mold portion including a lower cavity; and an upper mold portion including an upper cavity and a means for venting a gas during a rising of the foam, wherein the lower and upper mold portions are engageable so as to communicably engage the lower and upper cavities.
