Interdental device and container

Claim 2

A dental device comprising, a container and a stem, the container being adapted for holding a liquid therein and having a fixed opening enabling inserting the stem therethrough while holding the liquid therein, the stem having a front end segment of small cross-sectional dimensions and a rear end, of larger cross-sectional dimensions, and the front end segment decreasing in dimension in forward direction in each of mutually transverse directions, and being flexible in each of said transverse directions, the front end segment including a relatively sharp pick component at its front end, and the front end segment including a brush component rearwardly of the pick component.

Claim 3

A dental device according to claim 1 wherein, the front end segment is relatively flat, having a width dimension and a thickness dimension.

Claim 4

A dental device according to claim 2 wherein, the stem is of molded material, the brush component including bristles made up of extruded filaments, of uniform diameter extending through and molded in the material of the stem.

Claim 5

A dental device according to claim 3 wherein, the bristles extend in the width direction of the front end segment.

Claim 6

A dental device according to claim 3 wherein, the filaments are positioned side-by-side in direction axially of the stem, without spaces between next adjacent filaments in that direction.

Claim 7

A dental device according to claim 5 wherein, the filaments extend through the stem on both sides of the stem, and the filaments are of sufficiently small number in direction transverse to the blade as to present a generally flat shape of the brush component as viewed axially of the stem.

Claim 8

A dental device comprising, a container including an outer casing and an insert, a stem, the outer casing having an open top end and a closed bottom end, and having an upper large portion and a small lower portion joined together adjacent the middle of the outer casing by a conical portion, the casing being adapted to hold a liquid therein, the insert being of lesser transverse dimension than the outer casing, and being open at both its upper and lower ends, the insert being positioned in the outer casing with the upper ends of the insert and outer casing sealed together, and the insert terminating downwardly adjacent the middle of the outer casing, whereby communication is established between the lower portion of the casing and the upper portion thereof surrounding the insert, and the stem is positioned in the container extending through the insert and into the small lower portion of the casing, and the various elements being so positioned and dimensioned that when the container is positioned either in vertically reversed position or lying on a level surface, independently of the presence of the stem in the container, liquid therein when extending up to a predetermined level below the juncture of the casing portions will rise only to a position below the open inner end of the insert, whereby to prevent flow of the liquid out of the container.

Claim 9

A dental device comprising, a container including an outer casing and an insert, a stem, the outer casing having an open top end and a closed bottom end, and having an upper large portion and a small lower portion joined together adjacent the middle of the outer casing by a conical portion, the casing being adapted to hold a liquid therein, the insert being of lesser transverse dimension than the outer casing, and being open at both its upper and lower ends, the insert being positioned in the outer casing with the upper ends of the insert and outer casing sealed together, and the insert terminating downwardly adjacent the middle of the outer casing, whereby communication is established between the lower portion of the casing and the upper portion thereof surrounding the insert, and the stem is positioned in the container extending through the insert and into the small lower portion of the casing, and the various elements being so positioned and dimensioned that when the container is positioned either in vertically reversed position or lying on a level surface, independently of the presence of the stem in the container, liquid therein when extending up to a predetermined level below the juncture of the casing portions will rise only to a position below the open inner end of the insert, whereby to prevent flow of the liquid out of the container.
