This disclosure relates generally to noise protection devices for human ears often referred to as ear plugs.
Noise protection devices for insertion into the ear canal, more commonly referred to as ear buds or ear plugs, are utilized in a variety of applications. In each application, the ear plug is designed to protect the inner anatomical components of the ear from potentially damaging conditions which the ear may be exposed to. This may be accomplished by inserting a portion of the ear bud into the ear canal thereby blocking a portion of the canal from the potentially damaging environmental condition. Swimmers, for instance, may wear ear buds in order to prevent water from forcefully entering the ear canal thereby causing water-related damage. Similarly, individuals operating in loud environments may wear ear plugs in order to protect the ear from exposure damage due to high-noise levels.
No two ears are alike, however. The size, shape and general dimension varies from individual to individual. An ear bud which cannot securely fit within a portion of the ear canal may fail, either by slipping off or out of the ear, or otherwise not adequately protecting the ear from the potentially damaging environmental condition.
The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of every embodiment disclosed herein. It is intended to neither identify key or critical elements of the various embodiments nor delineate the scope of the disclosure. Its sole purpose is to present some concepts of the disclosure, in accordance with the various embodiments disclosed herein, in a simplified form as a prelude to the more detailed description that is presented later.
In one embodiment of the disclosure, an ear protection system may include an ear plug for insertion into at least a portion of a user's ear, the ear plug including an elastic component which may be heated to a compressible state and an inelastic component which remains in a substantially rigid state as the elastic component is heated to a compressible state, The ear protection system may further include a storage container including a display section having a case dimensioned to hold the ear plug, and a seal with at least a portion of the seal removable so as to expose the ear plug held in the case, and a lid fittable over the seal.
In another embodiment of the disclosure, an ear plug may include an elastic component including a chamber portion having an outer end and an opposed inner end, and a projection portion having a proximate end beginning at or adjacent to the chamber portion and a distal end opposed to the proximate end, the projection portion including a plurality of indentations, and an inelastic component including an internal portion, at least a part of the internal portion is substantially surrounded by the chamber portion of the elastic component, the internal portion and the chamber portion substantially co-axial. The ear plug may be heated to an elevated temperature, the elastic component achieving a compressionable state at the elevated temperature and the inelastic component maintaining a substantially rigid state at the elevated temperature.

With reference to
In one embodiment, elastic chamber 22 may be substantially cylindrical and may include an outer end 22A and an inner end 22B. In addition to chamber portion 22, elastic component 20 may further include a projecting portion 24 which may project away from chamber portion 22. As shown in the illustrated embodiment, projecting portion 24 may be formed into a crescent or semi-circular shape having a first or distal projection end 24A and a second or proximate projection end 24B. Projecting portion 24 may also include a plurality of cavities or indentations 26. Each of the indentations 26 may have a shallow enough depth to permit the existence of indentations on both sides of projecting portion 24, however embodiments where indentations 26 are provided on only the front or rear side are also contemplated within the disclosure. Furthermore, distal end 24A of projecting portion 24 may have a narrower width than the base end 24B of projecting portion 24 proximate to chamber 22, and in one embodiment the distal end 24A of projection portion 24 may come to a point. This change in thickness from proximate end 24B to distal end 24A may constitute a tapering of projecting portion 24.
Ear plug 10 may also include an insertion portion 34 defined between a first or distal insertion end 34B and second or proximate insertion end 34A. The proximate insertion end 34A may be defined adjacent to inner end 22B of chamber portion 22. For the embodiments of
In the various embodiments of ear plug 10, plastic component 30 may be manufactured from EVA (Ethylene-vinyl acetate), polyester material, such as polycaprolactone resin, compounded under heat. Such a compounding made in a double shear compounder or a similar mechanism, and the polyester resin may be combined with calcium carbonate and or glass bubbles as well as coloring agents or pigments. This resulting polyester based compound may be next formed into pellets for molding as part of the manufacturing process. The resulting compound may be mixed with additional polyester material as a master batch or can alternatively be used directly in molding depending on the desired color or cooling concentrations. The mixed compound may then be fed into an injection molding machine with variable parameters. Example parameters associated with the injection molding machine may include a barrel temperature of 120-220° F., a pressure of approximately 1500 psi at 50% speed, and a charging pressure of approximately 1000 psi. The material may then be injected into a material mold having superior heat conducting properties as the injected material. The plastic component may be thereby formed into a chamber held portion 32 and a chamber projection portion 34, or formed into an insertion member 60 with an internal portion 62 and cap 64. As one example of manufacturing, embodiments featuring a projecting portion 34 may begin with initially shaping projection portion 34 into a cone having a wider base end 34A than an insertion end 34B, so as to accommodate insertion in the user's ear canal. Once cooled, the formed plastic component 30 may then be prepared for its combination with elastic component 20, as further described herein.
Elastic component 20 may be formed from an elastic material including a thermoplastic elastomer, such pololefin blend, elastomeric alloys, syternic block copolymers, or other known or to be developed thermoplastic elastomers, and potentially as well as silicone, rubber or other elastic material. This elastic material may be injected over or around the formed plastic component 30, namely around chamber portion 32 or internal portion 62, depending on the embodiment.
Additional embodiments of ear plug 10 may include electronic noise canceling transistors molded into plug 10. Additives may also be included in the manufacture of either formable component 20 or plastic component 30 in order to adjust material characteristics of the components. For instance, micro glass and hollow glass spheres, also referred to as glass bubbles, may be added to increase the noise reduction rating of plug 10. In one embodiment, the glass bubbles may be in the approximately 17 micron range with a crush strength at or near 28,000 psi. Such an additive may assist in the molding process, the noise reduction range, or both. Furthermore, while elastic component 20 has an elevated temperature, as may be performed by a user as described herein, the user may cut or otherwise remove excess material inhibiting a tight or comfortable formation to the user's outer ear.
Lid 120, which may have an outer perimeter 122 substantially corresponding with the display outer perimeter 114. Lid outer perimeter 122 may then snap fit over display outer perimeter 114, or in another embodiment display outer perimeter 114 may snap fit over lid outer perimeter 122. Lid 120 may be removed, for instance, by grasping a handle 124 protruding from a portion of lid 120. In the illustrated embodiment, handle 124 protrudes from an area proximate to outer perimeter 122. A design surface 126 may also be provided so as to display a logo, symbol, text, or other design on a top surface of lid 120.
A display case 118 may be secured to the display side surface 112B. Case 118 may be sized and dimensioned to hold an embodiment of ear plug 10 between display case 118 and display side surface 112B. Case 118 may also be constructed of a substantially transparent material so that a stored ear plug 10 may be viewable from outside container 100. In order to access a stored ear plug 10, a tab 116 may be provided on lid side surface 112A. Tab 116 may be lifted in order to puncture a seal between outer perimeter 114 and surfaces 112A/112B thereby permitting a user to pull away a portion of the material and access ear plug 10 stored within display case 118.
