Definitions

  • the present invention is directed to a dispenser suitable for oral care compositions such a toothpaste.
  • Many commercial toothpaste packages have: a flexible tube body (to contain the toothpaste before dispensing) ; and a functionally attached dispenser having a cylindrical nozzle.
  • the nozzle is in fluid communication with the contents of the tube body.
  • a dose of toothpaste is extruded through the cylindrical nozzle of the dispenser and dispensed onto a tooth brush head.
  • the nozzle diameter/geometry is critical for defining a user’s experience in dispensing a desired tooth paste volume out from the package. Based on unpublished consumer testing, dosage is an important factor for an overall tooth brushing experience.
  • Too large a dosage may waste toothpaste (making the user feel as value is being lost) as well as may frustrate the user given the efforts associated with getting get rid of extra toothpaste (e.g., additional rinsing) .
  • Too large a dosage may waste toothpaste (making the user feel as value is being lost) as well as may frustrate the user given the efforts associated with getting get rid of extra toothpaste (e.g., additional rinsing) .
  • a dosage may not provide enough cleaning benefit to teeth or freshening benefit to the oral cavity.
  • Further complicating matters is the diversity of tooth brushes available to users. From example, some classic manual toothbrush brushes may have relatively large heads while smaller heads may be associated with some power brushes and specialty tooth brushes (e.g., children or gum sensitivity) .
  • the present invention attempts to address one or more of these needs by providing a dispenser, suitable for dispensing oral care composition, with a nozzle having a broadening nozzle opening that generally increases the dosing amount (using the same force in an otherwise classic dispenser) .
  • a dispenser for an oral care product comprising a base which is functionally attachable to a container containing an oral care composition (e.g., flexible tube) .
  • the dispenser further comprises a nozzle, which extends from the base.
  • the dispenser has a proximal opening at the interface of the nozzle and the base and an opposing distal opening.
  • a longitudinal axis intersects a centroid of a cross section of the proximal opening and a centroid of a cross section of the distal opening.
  • the distal opening has a cross-sectional area larger than the cross-sectional area of the proximal opening.
  • the nozzle is capable of being in fluid communication with the functionally attached container containing the oral care composition.
  • An example of such a container is a flexible tube.
  • An example of an oral care composition is a paste, preferably a toothpaste.
  • dispenser is a dispensing a dose of oral care composition that is wider than some classic dispensed doses thereby increasing the surface area to facilitate better dispersion or the oral care composition when administered in an oral cavity.
  • This is particularly advantageous with relatively high viscous oral care compositions, such as pastes, which may not disperse as readily as comparatively less viscous compositions.
  • One advantage of the dispenser herein is to minimize changes to existing products to minimize costs and capital investment, yet improve the user experience.
  • FIG. 1 is a front, cross section view, of a dispenser
  • FIG. 2 is a perspective view of the dispenser of FIG 1.
  • the terms “comprise” , “comprising” , “include” , “including” are meant to be non-limiting, i.e., other steps and other ingredients which do not affect the end of result can be added. Accordingly, the terms “consisting essentially of” and “consisting of” are embodied in the term “comprising” . As used herein, “consisting essentially of” means that the devices, apparatuses, methods, components, and/or compositions may include additional ingredients, but only if the additional ingredients do not materially alter the basic and novel characteristics of the claimed devices, apparatuses, methods, components, and/or compositions.
  • oral care composition is means a composition, which in the ordinary course of usage, is not intentionally swallowed for purposes of systemic administration of particular therapeutic agents but is rather retained in the oral cavity for a time sufficient to contact dental surfaces (i.e., tooth) and/or oral tissues for treatment.
  • the oral care product may be in various compositional forms including toothpaste, dentifrice, tooth gel, subgingival gel, denture cleaning composition, denture adhesive, or the like.
  • a preferred oral care composition is a paste composition, preferably a toothpaste composition.
  • oral care product means packaging containing one or more doses, preferably a plurality of doses, of oral care composition.
  • a dispenser is part of the packaging that contains the oral care composition.
  • a dispenser (1) for an oral care product comprises a base (9) .
  • the base (9) is functionally attachable to a container containing an oral care composition (not shown) .
  • the container is preferably a tube, preferably a flexible tube, more preferably a flexible toothpaste tube that is squeezable by a user to extrude the contained oral care composition from the subject tube through the functionally attached dispenser (1) .
  • the base (9) may have threading, preferably internal facing threading (11) , for functionally attaching the container (wherein the container has complimentary threading, preferably complimentary outward facing threading (not shown) ) .
  • the dispenser (1) further comprises a nozzle (13) .
  • the nozzle (13) extends from the base (9 (along a longitudinal axis (15) ) .
  • the nozzle (13) is in fluid communication with the functionally attached container.
  • the nozzle (13) extending from the base (9) has a proximal opening (19) at the interface of the nozzle (13) and the base (9) .
  • a distal opening (17) opposes the proximal opening (19) .
