Abstract

An earplug dispenser ( 10 ) includes a container ( 12 ), a cover ( 14 ), and a rotatable member ( 16 ). The container ( 12 ) is adapted to hold a quantity of earplugs ( 18 ) to be dispensed, and has a downwardly opening mouth ( 20 ). The cover ( 14 ) is attached to the container ( 12 ) to close the downwardly opening mouth ( 20 ). The rotatable member ( 16 ) is carried in the cover ( 14 ) for rotation about a vertical axis ( 22 ). The cover ( 14 ) has a base ( 24 ), a dispensing port ( 26 ) extending through the base ( 24 ), and a facing cylindrical surface ( 28 A) extending up from the base ( 24 ) and centered on the vertical axis ( 22 ). The rotatable member ( 16 ) has a plurality of conduits ( 29 ) extending vertically through the rotatable member ( 16 ), with each conduit ( 29 ) adapted to receive an earplug ( 18 ) from the container ( 12 ) and align one at a time with the dispensing port ( 26 ) to allow an earplug ( 18 ) carried in the conduit ( 29 ) to be dispensed downwardly through the dispensing port ( 26 ). The rotatable member ( 16 ) has an outer peripheral surface 34 at least partially surrounded by the cylindrical surface ( 28 A) and accessible through an aperture ( 30 ) formed in the cover ( 14 ) for manual rotation of the rotatable member ( 16 ). The peripheral and cylindrical surfaces ( 34,28 A) are sized relative to each other to prevent earplugs 18 from jamming therebetween during rotation of the rotatable member ( 16 ).

Claims (30)

1. An earplug dispenser comprising:

a container adapted to hold a quantity of earplugs to be dispensed, the container having a downwardly opening mouth;

a cover attached to the container to close the downwardly opening mouth, the cover having:

a base,

a dispensing port extending through the base, and

an inwardly facing surface extending up from the base, at least part of the inwardly facing surface being a cylindrical surface underlying the container and centered on a vertical axis, the inwardly facing surface having an aperture formed therethrough to an exterior of the cover;

a rotatable member carried in the cover for rotation about the vertical axis, the rotatable member having a plurality of conduits extending vertically through the rotatable member, each conduit adapted to receive an earplug from the container, the conduits arranged in an annular array about the vertical axis to align one at a time with the dispensing port to allow an earplug carried in the conduit to be dispensed downwardly through the dispensing port, the rotatable member having an outer peripheral surface surrounded by said inwardly facing surface of the cover and accessible through said aperture in the cover for manual rotation of the rotatable member, the peripheral and cylindrical surfaces sized relative to each other to prevent earplugs from jamming between said surfaces;

wherein:

the rotatable member further comprises an upwardly facing annular surface; and

the cover is a two-piece construction, with one of the pieces defining the inwardly facing surface, and the other piece defining a downwardly facing surface overlying part of the rotatable member.

2. An earplug dispenser comprising:

a container adapted to hold a quantity of earplugs to be dispensed, the container having a downwardly opening mouth;

a cover attached to the container to close the downwardly opening mouth, the cover having:

a base,

a dispensing port extending through the base, and

an inwardly facing surface extending up from the base, at least part of the inwardly facing surface being a cylindrical surface underlying the container and centered on a vertical axis, the inwardly facing surface having an aperture formed therethrough to an exterior of the cover;

a rotatable member carried in the cover for rotation about the vertical axis, the rotatable member having a plurality of conduits extending vertically through the rotatable member, each conduit adapted to receive an earplug from the container, the conduits arranged in an annular array about the vertical axis to align one at a time with the dispensing port to allow an earplug carried in the conduit to be dispensed downwardly through the dispensing port, the rotatable member having an outer peripheral surface surrounded by said inwardly facing surface of the cover and accessible through said aperture in the cover for manual rotation of the rotatable member, the peripheral and cylindrical surfaces sized relative to each other to prevent earplugs from jamming between said surfaces; and

wherein another part of the inwardly facing surface does not underlie the container; and

the cover includes a surface that overlies the another part of the inwardly facing surface and part of the rotatable member.

3. The earplug dispenser of claim 2 wherein:

the cover further comprises a cylindrical bearing surface extending from the base and centered on the vertical axis; and

the rotatable member comprises a cylindrical journal surface engaged with the cylindrical bearing surface to guide the rotatable member for rotation about the vertical axis.

4. The earplug dispenser of claim 3 wherein the cylindrical bearing surface is defined by an annular slot in the base.

5. The earplug dispenser of claim 2 wherein the cover further comprises an outwardly facing cylindrical surface opposite the inwardly facing surface, and the aperture defines a circumferentially extending window in the outwardly facing cylindrical surface to expose the peripheral surface of the rotatable member.

6. The earplug dispenser of claim 2 wherein the rotatable member is supported on said base.

7. The earplug dispenser of claim 2 wherein the dispensing port comprises a circular opening in the base.

8. The earplug dispenser of claim 2 wherein the dispensing port comprises a cylindrical wall extending downward from the base.

9. The earplug dispenser of claim 2 wherein the conduits have a cylindrical shape.

10. The earplug dispenser of claim 2 wherein the outer peripheral surface has a cylindrical shape that is interrupted by an array of angularly spaced indents.

11. The earplug dispenser of claim 2 further comprising a fastener extending along the vertical axis and engaged with the rotatable member in the base to limit upward movement of the rotatable member relative to the base.
