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.

Mold for forming a hearing protective device

A hearing device including a foam, a foam insertable portion, a component, and a foam handle portion, and a method of forming the same. The component is nestable with and bondable with the foam such that the component is at least partially within the foam insertable portion and the foam handle portion. The hearing protective device includes earplugs attached to a flexible cord, under-the-chin element, or headband. A method of making a hearing protective device including disposing a component into a mold, introducing a foam or foamable mixture into the mold, causing the foam to rise such that the component is nested within and bonded with the foam.

Eyewear

Safety eyewear is presented which is provided with particulate sealing around the inside periphery of the lens/lenses and having temples that provide adjustment of the eyewear to a pantoscopic angle. The eyewear is provided with an adjustable strap assembly for better fit to the wearer's head. The eyewear lens/frame includes a plurality of projections that define various pantoscopic angles. The temple end piece includes a set of recesses that engage the projections formed on the lens/frame which temple end piece is rotated relative to the lens/frame to set the pantoscopic angle. The adjustable strap assembly further adjust the fit of the eyewear and can be unbuckled for snaplocked attachment of the eyewear directly to other safety equipment such as noise suppression ear muffs, communication head phones, breathing masks and the like.

Earplug

Safety eyewear is presented which is provided with particulate and liquid sealing around a frame containing lens/lenses and having temples that provide adjustment of the eyewear to a pantoscopic angle. The eyewear is provided with an adjustable strap assembly for better fit to the wearer's head. The eyewear lens/frame includes a plurality of projections that define various pantoscopic angles. The temple end piece includes a set of recesses that engage the projections formed on the lens/frame which temple end piece is rotated relative to the lens/frame to set the pantoscopic angle. The adjustable strap assembly further adjust the fit of the eyewear and can be unbuckled for snaplocked attachment of the eyewear directly to other safety equipment such as noise suppression ear muffs, communication head phones, breathing masks and the like. A plurality of ventilation channels is disposed on the frame to provide indirect ventilation. The frame includes a skirt which is designed to prevent unwanted foreign matter, including liquids, from entering underneath the eyewear and making contact with the eyes of a user.

Piano lenses and associated eyewear incorporating parabolic and hyperbolic arcs are provided which are particularly useful in safety and recreational applications.

The present invention provides an earmuff device comprising an earmuff cup having at least a window portion which is formed of an optical material which transmits light rays in such a way that the human eye can see through the material to a degree that an earplug or other object inserted within the ear is visually perceivable to the human eye. In other words, the earmuff cup is formed of a transparent material or a translucent material so long as the earplug inserted within the wearer's ear is visually perceivable through the translucent portion of the earmuff cup. Because the earmuff cup is formed of a material that permits an individual, such as a supervisor or hearing conservationist, to perceive whether an earplug is inserted within the wearer's ear, the earmuff device of the present invention is particularly well suited for use in a dual hearing protection environment in which the previous method of compliance monitoring was time consuming and difficult.

Hearing protective devices having glow-in-the-dark properties are presented in the present invention. In an exemplary embodiment, the hearing protective device comprises a semi-aural device, an earplug, or an earmuff device. In all embodiments, a glow-in-the-dark material is incorporated into at least a part of the hearing protective device so that the glow-in-the-dark material continues to emit light for an extended period of time in a dark environment after the material has been excited by irradiation. Preferred and exemplary glow-in-the-dark materials comprise phosphorescent materials. The glow-in-the-dark materials may be disposed on a surface of the hearing protective part or dispersed throughout the material which forms this part.
