Abstract: A noise blocking band earplug has a band (12) with outer portions (44, 46) that are bent to prevent the ear-engaging pods (20, 22) from touching the ground, whether placed right-side-up or upside-down on the ground. When the middle region (32) of the band rests on a horizontal surface (64), a band inner end part (70) extends at an upward incline (C) with its outer end forming a second bend (80) so the outer end part (72) extends at a downward incline (D), with the second bend preventing the pods from touching the ground when the earplug is laid upside-down. At the second bend (80), the largely vertical height (J) of the band is increased and its outer surface (102) is made convex to provide pods for more readily pressing the pods against the outside of the ear canals.

Abstract: An elongated earplug of slow recovery material has one end portion (14) for use in large ear canals to effectively block noise therein and an opposite end portion (16) for use in small diameter ear canals to block noise while maintaining a moderate comfort level for the wearer. The opposite end portions of the earplug are of different colors, to enable a person picking up the earplug to quickly determine which end to place in the ear as well as to identify the earplug as a dual type. The larger end is preferably of a lighter color such as yellow, then the darker end which is of a darker color such as medium to dark green or orange, to emphasize the largeness of the large end and the smallness of the small end. One dual earplug has a small end portion which is tapered along most of its length, at an included tapered angle (B) of about 15.degree.

Abstract: An earplug is described, which includes an elastic earplug body (12) and a metal part (14) mounted to the body to form an earplug that can be detected by a metal detector. The metal part (14) is in the form of a band that is clamped around the body. Where the body includes a narrow stem (24) and at least one flange (34) extending from a position (56) on the body and at a radially outward and rearward incline therefrom, the band can be attached to a location (62) lying a small distance rearward of the position where the flange emerges from the stem, so the band is hidden and is prevented from directly engaging a person's ear canal.

Abstract: A combination of earmuff and eyeglass assemblies (12, 14) are provided, that facilitate adjustment of the position of the eyeglass (40) on the wearer and the raising and lowering of the eyeglass, in a construction that avoids interference with movement of the earmuffs (20, 22) against each other. The eyeglass assembly includes a pair of temple bar devices (46, 48) that each comprises two pivotally connected bars (50, 52), with the first bar having a rear end (56) pivotally mounted on a top portion (134) of an earmuff shell (24), and with the second bar pivotally connected about horizontal and vertical axes (74, 81) to one side of the eyeglass. A ball-and-socket coupling (80) is mounted on the top portion of each earmuff shell, with each socket (102) having a vertical slot portion (110) that allows the temple bar devices to be pivoted up and down, and with each socket having a horizontal slot portion (112) that allows the earmuffs to move together.

Abstract: A container is described which can hold multiple small articles such as earplugs, and which can be inserted into a dispenser where the contents can be readily released. The container includes a box (30, FIG. 3) whose bottom wall includes a pair of flaps (50, 52) having inner ends (54, 56) pivotally connected to the bottoms of opposite side walls, and having outer portions (64, 66) that lie adjacent to each other. A release device (34) holds the outer portions of the flaps together to prevent them from pivoting down until the release device is pulled out, when the flaps pivot down and the articles fall out. The outer portion of each flap includes an upstanding tab (76, 78, FIG. 5) with a horizontal slot (82), and the release device includes a cardboard plate which is received in the slot.

Abstract: An apparatus is described which can receive a large number of earplugs from a box and dispense one or two of them at a time to a worker. The apparatus includes a wheel (22, FIG. 1) which is rotatable on a frame (12) and which has holes (24) that move in a circular path and that can each receive a single earplug (16). As each hole moves over a dispense passage 18, the earplug in the hole can fall out, and be dispensed. A barrier (42, FIG. 2) lying above the wheel, prevents an earplug from falling into a hole that lies at the passage. The barrier covers only one side (52) of the path (32) of the holes, to allow a deformed earplug to move along the other, uncovered side (54) of the path. The wheel has a narrow slot (80) extending from each hole to the periphery, so a tool can be projected through a frame opening (84) and through the slot to dislodge an earplug stuck in a wheel hole.

Abstract: A band earplug apparatus is described, of the type which includes a pair of earplug devices (20, 22) lying on the ends of a band (12) that fits halfway about a person's head, which avoids soiling of the earplug devices when the band is laid on a dirty surface. The band is designed so its middle portion (24) rests stably on a horizontal surface (5), and with the end portions then extending at an incline (A) away from the horizontal surface to hold the ends (14, 16) of the band and the earplug devices (20, 22) thereon spaced from the horizontal surface.

Abstract: A container is described which can hold multiple small articles such as earplugs, and which can be inserted into a dispenser where the contents can be readily released. The container includes a box (30, FIG. 3 ) whose bottom wall includes a pair of flaps (50, 52) having inner ends (54, 56) pivotally connected to the bottoms of opposite side walls, and having outer portions (64, 66) that lie adjacent to each other. A release device (34) holds the outer portions of the flaps together to prevent them from pivoting down until the release device is pulled out, when the flaps pivot down and the articles fall out. The outer portion of each flap includes an upstanding tab (76, 78, FIG. 5 ) with a horizontal slot (82), and the release device includes a cardboard plate which is received in the slot.

Abstract: An apparatus is described which can receive a large number of earplugs from a box and dispense one or two of them at a time to a worker, which avoids touching of the earplugs by any other person. The apparatus includes a wheel (22, FIG. 1 ) which is rotatable on a frame (12) and which has holes (24) that are each capable of holding a single earplug (26). As the wheel turns, earplugs fall into the holes. As each hole moves to a dispense location (30), the earplug in the hole can fall out of the hole along a dispense passage (16). A barrier (42) lying above the wheel, prevents an earplug from falling into a hole that lies at the dispense location, and sweeps away any second earplug which lies partially within a hole approaching the dispense location. A large number of earplugs are contained in a box (80) which is installed in an open top (82) of the dispenser.

Abstract: Earplug assemblies are provided for mounting at the ends of a resilient band, which readily deform to tightly seal to the walls of the ear that surround the entrance to the ear canal. Each assembly includes a shell having a closed forward end that presses against the ear and an open rear end that receives an armature mounted on the band. The shell has a front end tapered at a large angle such as 90.degree., while the armature has a forward portion tapered at a small angle such as 20.degree., to leave an air gap between the forward portions of the shell and armature. With the forward tip of the armature pressing against the center of the shell front, outer portions of the shell front can deflect rearwardly and radially inwardly into the air gap.

Abstract: An earplug of the slow recovery type is described, which has open cells for expelling gas to the outside during compression, but which resists the entry of water through the outside and the soiling of the outside by dirt. The earplug includes a body formed of pressure-molded slow recovery resilient foam material forming multiple gas-filled shells. The plug body has a surface region forming a skin wherein the average cell cross-sectional area is less than half that of cells at the center of the body, and is less than one-tenth millimeter, the surface region being primarily continuous.

Abstract: A container is described, of a type which includes a resilient cover whose rearward portion is heat sealed to the flange of a container bottom or body and whose front can be bent up to gain access to the recess in the body. The cover is cut from a previously rolled sheet which is arched, and the convex side of the sheet faces upwardly so the front of the container cover tends to stay closed. The cover is heat sealed to opposite side flanges at locations lying forward of the rear of the recess by at least 25% of the length of the recess, to thereby more firmly keep the cover closed. The front of the cover and body are formed with aligned holes forward of the recess, so the container can be stored on a rod without the contents spilling out.

Abstract: An ear noise protector apparatus is described, which provides a high level of noise protection, can be worn comfortably, and is economical to use. The apparatus includes a resilient head band with ear protector holders at either end, and a pair of ear protectors that are detachably mounted to the holders. Each ear protector includes a cap of slow recovery resilient deformable material, with a tapered central projection that can be received in the end of an ear canal, and an outer dish-shaped portion that can fit against the ear walls that surround the opening to the ear canal. The head band supplies sufficient force to maintain the cap in a deformed state wherein it conforms to the ear portion that surrounds the ear canal, to form a good seal therewith after being pressed firmly in place.
