Abstract:
An oral care implement having movable and fixed tooth cleaning elements. The oral care implement may include a handle and a head coupled to the handle. The head may include a base that is coupled to the handle and a resilient bridge coupled to the base. The resilient bridge may be flexible between a normal state in which a portion of the resilient bridge is spaced from the base by a gap and a flexed state in which a portion of the resilient bridge is moved toward the base. Tooth cleaning elements may be coupled to the resilient bridge. Furthermore, the resilient bridge may include one or more apertures through which tooth cleaning elements that are fixed to the base may extend.
Abstract:
An oral care implement having a handle, a head, and at least one movable cleaning element coupled to the head. The movable cleaning element may be used as an interdental cleaner. The movable cleaning element may be positioned within a loop formed by fixed cleaning elements on the head. The movable cleaning element may be coupled to an actuator that moves the movable cleaning element between a first position wherein a distal tip of the movable cleaning element is spaced a first distance from a front surface of the head and a second position wherein the distal tip of the movable cleaning element is spaced a second distance from the front surface of the head, the second distance being greater than the first distance. The movable cleaning element may maintain the first and second positions until subsequent actuation of the actuator.
Abstract:
An oral care implement having tooth cleaning elements and an elastomeric soft tissue cleanser. In one aspect, the oral care implement has a handle and a head (110) coupled to the handle, an elastomeric soft tissue cleanser having a plurality of protuberances (152) extending from a rear surface of the head (110), and a plurality of tooth cleaning elements (115) extending from a front surface of the head. The protuberances (152) of the elastomeric soft tissue cleanser collectively define a convex longitudinal side profile and comprise at least one convex transverse top profile. The plurality of tooth cleaning elements (115) collectively define a concave longitudinal side profile and comprise at least one concave transverse top profile.
Abstract:
An oral care implement that includes a conical tuft of bristles. In one embodiment, the invention is an oral care implement that includes a handle and a head coupled to the handle, the head having a front surface. A plurality of tooth cleaning elements extend from the front surface of the head. The plurality of tooth cleaning elements include a conical tuft that has a bristle wall having an inner surface defining a cavity, the cavity having a transverse cross-sectional area that increases with distance from the front surface of the head. Furthermore, in some embodiments the bristle wall terminates in an annular top surface that is inclined relative to the front surface of the head. In some embodiments, the head includes more than one of the conical tufts, such as two of the conical tufts or four of the conical tufts.
Abstract:
An oral care implement that includes a head having tooth cleaning elements including at least one conical tuft of bristles. The conical tuft of bristles defines a cavity that has a transverse cross-sectional area that increases with distance from the head. The tooth cleaning elements may also include one or more arcuate cleaning elements that at least partially surround the conical tuft. The tooth cleaning elements may also include multi-height bristle tufts along lateral sides of the head. Furthermore, the head may have two conical tufts such that one of the conical tufts is oriented at a smaller acute angle relative to the head than the other conical tuft and/or one of the conical tufts is taller than the other conical tuft.
Abstract:
Disclosed is an oral care implement, comprising: a body comprising a handle and a head, the body having a cavity, and the head having at least one oral care element extending therefrom; a movable wall in the cavity that divides the cavity into first and second reservoirs, the first reservoir for storing an oral care fluid; a fluid outlet through which the oral care fluid is dispensable to an exterior of the oral care implement; a passageway fluidly connecting the first reservoir with the fluid outlet; a control valve movable between a first position and a second position for preventing and permitting fluid flow from the first reservoir, respectively; a first opening fluidly connecting the second reservoir with the exterior of the oral care implement; and a first check valve for permitting and restricting air flow into and out of the second reservoir from the exterior.
Abstract:
Disclosed is an oral care implement, comprising: a body comprising a handle, a head having at least one oral care element extending therefrom, and at least one fluid outlet; a reservoir in the body and for storing an oral care fluid; and a pump in the body for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises an umbrella check valve circumferentially surrounding a duckbill check valve. Also disclosed is a method of manufacturing an oral care implement, comprising: providing a body comprising a base having first and second holes extending therethrough; and fitting to the body a unitary component comprising first and second valves at a position at which the first valve blocks the first hole and the second valve blocks the second hole, wherein the first valve comprises an umbrella check valve that circumferentially surrounds the second valve.
Abstract:
Toothbrushes comprising components with light transmitting and structural characteristics provide enhanced visual and other sensory effects. The components in combination are generally chemically compatible and function to provide areas of varying visibility of features and optionally varying scent release.
Abstract:
A toothbrush includes a handle and a head mounted to the handle. The head may generally include a membrane attached to it and configured for attachment to a cleaning element. The membrane may be generally dome shaped and may be resiliently flexible when a brushing force is applied. A plurality of cleaning elements is mounted to the membrane. The cleaning elements may be attached using anchor free tufting. In addition, the cleaning elements may be sufficiently spaced so as to allow separation of the melted portion of the cleaning elements. In another arrangement, the head may also include walls or dams positioned between the cleaning elements. The walls prevent the melted portion of the cleaning elements from merging with the melted portion of another cleaning element. This isolation of the molten nylon allows the cleaning elements to move independently of each other.
Abstract:
An oral care implement is provided having a handle and a head with tooth cleaning elements extending from fixed pods. Additional tooth cleaning elements extend from one or more central pods suspended between the fixed pods via a bridge. The bridge may be formed from an elastomer and permit the one or more central pods to move from an initial position toward the head during use. The central pods, the bridge and outer portions of the fixed pods may be formed as a unitary structure. When a single central pod is employed, a flexible section may be disposed in the middle of the central pod so that cleaning elements extending from either end of the central pod can move toward one another during use.
