Definitions

  • the invention relates to an applicator device for applying at least one application agent to fibrous materials.
  • the problem addressed by the invention is particularly that of providing an applicator device which offers easy handling and effective protection against any unintentional discharge of the application agent.
  • This problem is solved according to the invention by the features of claim 1 and of the independent claims. Additional embodiments are specified in the dependent claims.
  • an applicator device for applying at least one application agent to fibrous materials comprising a housing unit which encloses at least one depot volume for storing the at least one application agent and at least one application volume connected to the depot volume.
  • Dividing a total volume into the depot volume and the application volume allows an application device to be provided by means of which particularly a liquid application agent can be applied safely to fibrous materials.
  • the division allows the application volume to be advantageously embodied as small, thereby particularly decreasing the position dependency of a supply to application sites where the application agent is to be applied to the materials.
  • a “depot volume” is particularly understood in this context as a volume enclosed by the housing unit, which is provided for accommodating and storing the application agent.
  • An “application volume” is particularly understood as a volume that borders at least one application site, preferably at least two application sites. The application volume is preferably situated downstream of the depot volume in terms of flow, and is designed to hold the application agent immediately prior to application to the fibrous materials, especially hair.
  • An “application volume” particularly is not understood as a channel, i.e., an open space, which has a specified flow direction and is provided for conducting the application agent from a depot volume to an application site. “Provided” is particularly understood to mean specially equipped and/or designed.
  • an “application agent” is particularly understood to mean a liquid, paste-like or powdered medium which is provided for application to hair, particularly a hair dye, hair treatment agent, hair gloss, dispersion, body modifying agent, and/or pharmaceutical hair treatment agent.
  • the application agent can be embodied as a single-component agent or as a multicomponent agent.
  • a “single-component agent” is understood as an agent that is stored ready for use in the application agent container.
  • a “multicomponent agent” is understood particularly as an agent that comprises two separately stored components, which are designed to be mixed together for application.
  • the size of the application volume is smaller than the size of the depot volume.
  • a particularly safe filling of the application volume can thereby be realized.
  • the application volume is no more than half as large as the depot volume.
  • the applicator device prefferably has a pump unit, which is provided to at least support a filling of the application volume with the at least one application agent.
  • a particularly advantageous filling of the application volume can thereby be achieved.
  • the pump unit is preferably provided for inducing the application agent to a turbulent flow inside the depot volume, as a result of which, for one thing, an advantageous thorough mixing of the application agent can be achieved, particularly when the application agent is embodied as a multicomponent agent, and for another, with the turbulent flow, a pumping effect for filling the application volume can be easily achieved.
  • the pump element of the pump unit is preferably embodied as spherical. However, other pump units are also conceivable in principle.
  • the pump element to be movably connected to the housing unit, for example, in the form of a pendulum, which is designed for suspension inside the depot volume.
  • the pump unit it is conceivable for the pump unit to be provided merely for exciting the housing unit to oscillation or vibration.
  • a “pump unit” is understood as a unit that is provided for exciting turbulence, a laminar flow and/or a change in pressure in the application agent.
  • the pump unit preferably comprises at least one pump element arranged in the depot volume and/or the application volume, which is provided for achieving a pumping effect.
  • a flow can advantageously be easily generated in the depot volume, with which the application agent can advantageously be thoroughly mixed, and can advantageously be conducted from the depot volume into the application volume.
  • a pump element is particularly understood to be an element that is movable relative to the housing unit and is provided for exciting the application agent to a flow, for example, a pendulum, an impeller, or some other element.
  • the pump element can be provided for guided motion, for example, a pump element that is mounted so as to rotate around a rotational axis, or for free motion.
  • the pump element is arranged freely movable in the depot volume that is enclosed by the housing unit.
  • the pump unit can be particularly simple in design, particularly allowing a simple, manual pump unit to be realized.
  • “Freely movable in the depot volume” is particularly understood in this context to mean that the pump element is not fastened to the housing unit that encloses the depot volume. Movement of the pump element is preferably limited to the depot volume.
  • the at least one pump element is advantageously spherical. This allows a particularly simple pump element to be realized.
  • the applicator device has a mixing unit, which comprises a least one mixing element inserted into the depot volume and/or the application volume, and provided for thoroughly mixing the application agent.
  • a mixing unit which comprises a least one mixing element inserted into the depot volume and/or the application volume, and provided for thoroughly mixing the application agent.
  • the pump unit and the mixing unit are preferably embodied as at least partially integral.
  • the number of components can thereby be advantageously reduced.
  • the pump element and the mixing element are embodied as integral.
  • the mixing unit it is additionally or alternatively conceivable for the mixing unit to have a mixing element that is arranged in the application volume.
  • the applicator device has a divider unit, which is provided for at least partially uncoupling the application volume in terms of flow from the depot volume.
  • Uncoupling in terms of flow is particularly understood in this context to mean that an exchange of volume between the application volume and the depot volume is at least partially prevented.
  • a flow of the application agent in the depot volume particularly a turbulent flow, is transferred no more than partially to the application agent in the application volume.
  • the device is especially easy to handle particularly if the divider unit is provided for at least partially preventing the application agent from flowing back from the application volume into the depot volume.
  • the application agent held in the application volume can be prevented from flowing back into the depot volume, thereby at least largely ensuring adequate filling of the application volume.
  • the divider unit preferably comprises rigid separator elements, which particularly preferably form a labyrinthine structure.
  • the divider unit it is also conceivable for the divider unit to be embodied as a valve unit, for example, in the form of a leaf valve, which acts as a flow-check valve.
  • the housing unit is further advantageous for the housing unit to be substantially dimensionally stable, in order to prevent a partial vacuum of the application agent at least during use. It can thereby be prevented that too much application agent is discharged during handling as a result of a partial vacuum, thereby allowing the hair to be wetted uniformly while simultaneously preventing application agent from being applied to the scalp.
  • Preventing is particularly understood in this context to mean that with normal handling of the applicator device, i.e., when the housing unit is grasped by a user, the housing unit is at least dimensionally stable enough that application agent is prevented from escaping through the application gaps.
  • the housing unit is preferably at least partially rigid. “Rigid” is particularly understood in this context to mean that a force exerted on the housing unit for the purpose of reducing the application volume or depot volume enclosed by the housing unit by at least 10 percent will result in the destruction of the housing unit.
  • an applicator device for applying at least one application agent to fibrous materials, particularly an applicator device for applying an application agent to hair, with a separation unit having at least two separator elements, which form at least one application gap which is designed to receive hair for application of the application agent, and with at least one application volume that is at least partially enclosed by at least one of the separator elements.
  • a separation unit having at least two separator elements, which form at least one application gap which is designed to receive hair for application of the application agent, and with at least one application volume that is at least partially enclosed by at least one of the separator elements.
  • An “application gap arranged between two separator elements” is particularly understood as an open space between two adjacent separator elements, spaced from one another.
  • An “application volume” is particularly understood as a volume for accommodating and storing the application agent.
  • a “separator element” is particularly understood in this context as an element of the separation unit that is provided for introducing the hair placed in the separation unit into the at least one application gap or guiding it past the application gap.
  • “An application volume that is at least partially enclosed by at least one of the separator elements” is particularly understood to mean that the internal contour of at least one of the separator elements forms a wall for the application volume.
  • the separator elements preferably partially span the application volume, whereby the hairs, when placed in the application gap, penetrate into the application volume in which the application agent is stored and become wetted.
  • the application volume is preferably at least one milliliter in size.
  • the application volume is particularly preferably designed to at least partially accommodate hair that is introduced into the at least one application gap. In this manner, hair can be passed through the application agent stored in the application volume, allowing the hair to be particularly easily provided with application agent.
  • the application gap preferably has a constant gap width in at least one partial area along its main direction of extension.
  • part of the at least one application gap has a gap width that varies along at least one direction.
  • An opening width in the region of a tip line can preferably be larger than the gap width, wherein the gap width can also decrease starting from the tip line and extending in the direction of a base line.
  • the at least one application gap can also have a conical, angled, or wedge-shaped structure.
  • the application volume and the at least one application gap preferably merge with one another in at least one partial region.
  • a particularly advantageous embodiment for applying the application agent to hair can thereby be achieved. “Merging” is particularly understood in this context to mean that at least part of the volume enclosed by the separator elements can be assigned both to the application gap and to the application volume.
  • the applicator device comprises a depot volume which is connected to the application volume.
  • a particularly advantageous quantity of the application agent can be introduced into the applicator device, wherein a particularly reliable supply of the application gap with the application agent can be achieved, while at the same time, application agent can be prevented from unintentionally escaping.
  • the applicator device has a porous material, which is introduced at least partially into the at least one application volume.
  • a porous material is particularly understood in this context as a material that forms cavities designed for conducting the application agent, particularly a sintered material, a sponge material, or a wicking material, for example, a fibrous material.
  • an applicator device for applying at least one application agent to fibrous materials comprising a separation unit which has a comb-like structure with at least two separator elements and at least one application gap arranged between the separator elements, and comprising a housing unit which encloses at least one depot volume in which the application agent is held, and comprising at least one application site, which is arranged in the area of the at least one application gap, wherein the width of the application gap, at least in the area of the application site, is smaller than a barrier width.
  • a continuous, unintentional escape of application agent can thereby be prevented, as a result of which the applicator device is particularly easy to operate and can especially be intended for private use.
  • a “barrier width” is particularly understood in this context as a maximum width that a gap having a constant gap width can have without the application agent escaping through the gap when a pressure corresponding to a liquid column of 5 centimeters of the application agent is applied.
  • the barrier width is therefore dependent particularly on properties of the application agent, for example, an adhesive force, cohesive force, frictional forces, capillary forces, and/or a flow resistance.
  • the width of the at least one application gap is therefore adapted to the application agent being used.
  • the application gap can have different gap widths based upon the application agent that is used.
