Definitions
- the present invention relates to a tool for eyelash extension. It also relates to a method for extending eyelashes.
- Eyelash extension is used for enhancing the length of a person's natural eyelashes.
- Extension elements such as artificial eyelashes, are normally mounted to the eyelashes to be extended one by one, using an adhesive to attach them individually.
- an extension element is dipped in the adhesive and then directly attached to one of the eyelashes to be extended.
- adhesives There are different types of adhesives available, and a commonly used type is cyanoacrylate. Cyanoacrylate may cause skin irritation or have other hazardous effects for both the person performing the eyelash extension, and for the person whose eyelashes are being extended.
- Another drawback of dipping the extension element in the adhesive, which is typically in its melted form, and then attaching the extension element directly is that it is difficult to control the amount of adhesive applied to the element.
- the present invention is based on the realisation that if the extension elements are prepared by providing the adhesive and allowing it to bond to the extension element, the amount of adhesive may be more easily controlled. By providing a tool comprising a heating element, the adhesive attached to the extension element may then be melted just before attaching the extension element to the eyelash to be extended.
- a tool for eyelash extension comprises a handle portion to be held by one hand, and a first leg portion and a second leg portion for separating at least one eyelash from adjacent eyelashes.
- the two leg portions extend from the handle portion and are held apart by spring action.
- the tool further comprises a heating portion for melting an adhesive attached to an extension element, said heating portion being attached to said handle portion.
- the handle portion may be made in one piece, or it may comprise a plurality of parts. According to at least one exemplary embodiment, the handle portion may comprise a first and a second handle part connected to each other in one end, like a tweezer.
- the handle portion may suitably be made from a metallic and/or a plastic material.
- the first leg portion and the second leg portion may suitably also be made from a metallic and/or a plastic material.
- the two leg portions and the handle portion may be made in one piece, or they may be made from separate parts which are attached to each other.
- the two leg portions being held apart by spring action is meant that when no external force is applied to the two leg portions, they are held at a certain distance from each other, and when a force is applied to both or one of the leg portions urging them to approach each other or be brought further apart, the spring action works to return the leg portions to their original position. This is advantageous from an ergonomic perspective for the person performing the eyelash extension, since no force has to be applied to keep the eyelash to be extended out of contact from the adjacent eyelashes once it has separated from them.
- the heating portion being attached to said handle portion is meant that the heating portion is arranged on or inside said handle portion.
- the heating portion may be integrated into the handle portion, and in other embodiments the heating portion may be external of the handle portion.
- the heating portion comprises at least one resistor, preferably two resistors, for creating the heat.
- the heating portion may further comprise additional resistors e.g. for regulating the temperature and as disconnectors.
- a separate source of energy may be needed to heat the heating portion, such as e.g. a battery or a cable for connecting the tool to a source of electricity.
- the two leg portions are pointed.
- the two leg portions have a narrowing shape. This makes it easier to separate at least one eyelash from the adjacent eyelashes.
- the tool has a length of 8 - 20 cm, and/or the handle portion has a length of 6 - 18 cm, and/or the first leg portion and the second leg portion have a length of 1 - 4 cm.
- the dimensions are suitably adapted such that the tool may be held by one hand.
- the first leg portion and the second leg portion are held apart 0.3 - 2 cm by said spring action. This distance is suitable for separating the adjacent eyelashes from the eyelash to be extended enough, such that the extension element or the adhesive is not in contact with any of the other eyelashes while mounting it.
- the heating portion is configured to be heated to a temperature of 80 - 150°C, preferably 110 - 130°C. These temperature intervals are advantageous since the heating portion is to be used to melt the adhesive attached to the extension element, and adhesives which are suitable for eyelash extension typically have a melting point covered by these intervals.
- the two leg portions are inclined in relation to said handle portion.
- the two leg portions extend at an angle from said handle portion.
- the transition between the handle portion and the two leg portions may be curved. Having leg portions inclined in relation to the handle portion is advantageous since it enables the person performing the eyelash extension to have a more ergonomic work position than if the two leg portions would not be inclined.
- a surface of the heating portion is U-shaped or V-shaped.
- the heating portion comprises at least two walls facing each other.
- the two walls facing each other is meant that the surface of each wall which is intended to be heated has a respective surface normal, and the two respective surface normals intersect each other. This also enables having a more uniform distribution of heat, which enhances the melting of the adhesive.
- the heating portion comprises a user protection cover made of a plastic material. This is advantageous to prevent the user from burning while using the tool.
- a method for extending eyelashes using a tool according to the first aspect of the present invention comprises the steps of:
- adhesive include compositions that may act as bonding between the eyelash and the extension element, e.g. hot melts and waxes.
- the method according to the second aspect of the present invention is a general method which may be performed using other tools than a tool according to the first aspect of the present invention.
- the extension element may be any element suitable for attaching to an eyelash.
- the extension element will be an artificial eyelash, but other types of extension elements are also conceivable, such as for example feathers or other decorations.
- the adhesive is an adhesive composition which may be heated such that it melts.
- the adhesive composition may comprise a plurality of different components.
- the adhesive may be provided on the extension element for example by dipping a portion of the extension element in the adhesive while it is in its melted form. The adhesive is then allowed to solidify e.g. while it cools, whereafter a desired amount of adhesive is attached to the extension element. Preferably only a portion of the extension element is covered with the adhesive, but in some embodiments the whole extension element may be covered.
- separating at least one eyelash to be extended from adjacent eyelashes is meant that the eyelash to be extended should not be in contact with the adjacent eyelashes. This is to avoid adhering the extension element to the adjacent eyelashes when mounting it to the eyelash to be extended.
- the step of heating the adhesive attached to the extension element using said heating portion, such that said adhesive melts, is suitably performed by gripping the extension element using a tool, such as a tweezer, and holding the extension element against or above the heating portion.
- the temperature of the heating portion is suitably adapted to the melting point of the adhesive, to enable melting of the adhesive.
- the extension element When mounting the extension element to one of the eyelashes which has been separated out, the extension element is suitably still gripped with tool such as a tweezer. Once the step of fastening the extension element by solidifying of said adhesive has been performed, the extension element may be released from the tweezer. Due to the solidifying which results in a bonding of the adhesive, the extension element will then stay attached to the eyelash to be extended.
- tool such as a tweezer.
- the extension element comprises at least one artificial eyelash.
- the extension element may comprise a strand or a bundle of artificial eyelashes.
- the artificial eyelashes may suitably be made of a synthetic material, or they may be made of hair.
- Other types of extension elements are also conceivable, such as feathers or other decorations of different materials and shapes.
- the adhesive is a composition selected from a group comprising: hot melts, low temperature melting hotmelts waxes such as microcrystalline waxes and combinations thereof.
- hot melts including low temperature melting hotmelts (such as ethylene vinyl acetate polymer) and micro crystalline waxes the bond to the lash is established upon solidification.
- Low temperature melting hotmelts and waxes are advantageous as they melt to liquid form at temperatures which is safe to use close to the human eye.
- said composition also comprises:
- Using one or more pigments in the composition may be beneficial to reduce the visibility of the adhesive, such that the extension looks more natural.

Description
- The present invention relates to a tool for eyelash extension. It also relates to a method for extending eyelashes.
- Eyelash extension is used for enhancing the length of a person's natural eyelashes. Extension elements, such as artificial eyelashes, are normally mounted to the eyelashes to be extended one by one, using an adhesive to attach them individually. Conventionally, an extension element is dipped in the adhesive and then directly attached to one of the eyelashes to be extended. There are different types of adhesives available, and a commonly used type is cyanoacrylate. Cyanoacrylate may cause skin irritation or have other hazardous effects for both the person performing the eyelash extension, and for the person whose eyelashes are being extended. Another drawback of dipping the extension element in the adhesive, which is typically in its melted form, and then attaching the extension element directly is that it is difficult to control the amount of adhesive applied to the element.
- It is an object of the present invention to alleviate at least some of the mentioned drawbacks of the prior art and to provide an improved tool and a method for extending eyelashes. This and other objects, which will become apparent in the following, are accomplished by a tool and a method as defined in the accompanying independent claims.
- The term exemplary should in this application be understood as serving as an example, instance or illustration.
- The present invention is based on the realisation that if the extension elements are prepared by providing the adhesive and allowing it to bond to the extension element, the amount of adhesive may be more easily controlled. By providing a tool comprising a heating element, the adhesive attached to the extension element may then be melted just before attaching the extension element to the eyelash to be extended.
- According to a first aspect of the present invention, a tool for eyelash extension is provided. The tool comprises a handle portion to be held by one hand, and a first leg portion and a second leg portion for separating at least one eyelash from adjacent eyelashes. The two leg portions extend from the handle portion and are held apart by spring action. The tool further comprises a heating portion for melting an adhesive attached to an extension element, said heating portion being attached to said handle portion.
- The handle portion may be made in one piece, or it may comprise a plurality of parts. According to at least one exemplary embodiment, the handle portion may comprise a first and a second handle part connected to each other in one end, like a tweezer. The handle portion may suitably be made from a metallic and/or a plastic material.
- The first leg portion and the second leg portion may suitably also be made from a metallic and/or a plastic material. According to at least one embodiment the two leg portions and the handle portion may be made in one piece, or they may be made from separate parts which are attached to each other. By the two leg portions being held apart by spring action is meant that when no external force is applied to the two leg portions, they are held at a certain distance from each other, and when a force is applied to both or one of the leg portions urging them to approach each other or be brought further apart, the spring action works to return the leg portions to their original position. This is advantageous from an ergonomic perspective for the person performing the eyelash extension, since no force has to be applied to keep the eyelash to be extended out of contact from the adjacent eyelashes once it has separated from them.
- By the heating portion being attached to said handle portion is meant that the heating portion is arranged on or inside said handle portion. In some embodiments the heating portion may be integrated into the handle portion, and in other embodiments the heating portion may be external of the handle portion. The heating portion comprises at least one resistor, preferably two resistors, for creating the heat. The heating portion may further comprise additional resistors e.g. for regulating the temperature and as disconnectors. A separate source of energy may be needed to heat the heating portion, such as e.g. a battery or a cable for connecting the tool to a source of electricity.
- According to an exemplary embodiment of the present invention, the two leg portions are pointed. In other words, the two leg portions have a narrowing shape. This makes it easier to separate at least one eyelash from the adjacent eyelashes.
- According to an exemplary embodiment of the present invention, the tool has a length of 8 - 20 cm, and/or the handle portion has a length of 6 - 18 cm, and/or the first leg portion and the second leg portion have a length of 1 - 4 cm. The dimensions are suitably adapted such that the tool may be held by one hand.
- According to an exemplary embodiment of the present invention, the first leg portion and the second leg portion are held apart 0.3 - 2 cm by said spring action. This distance is suitable for separating the adjacent eyelashes from the eyelash to be extended enough, such that the extension element or the adhesive is not in contact with any of the other eyelashes while mounting it.
- According to an exemplary embodiment of the present invention, the heating portion is configured to be heated to a temperature of 80 - 150°C, preferably 110 - 130°C. These temperature intervals are advantageous since the heating portion is to be used to melt the adhesive attached to the extension element, and adhesives which are suitable for eyelash extension typically have a melting point covered by these intervals.
- According to an exemplary embodiment of the present invention, the two leg portions are inclined in relation to said handle portion. In other words, the two leg portions extend at an angle from said handle portion. The transition between the handle portion and the two leg portions may be curved. Having leg portions inclined in relation to the handle portion is advantageous since it enables the person performing the eyelash extension to have a more ergonomic work position than if the two leg portions would not be inclined.
- According to an exemplary embodiment of the present invention, a surface of the heating portion is U-shaped or V-shaped. An advantage of this is that it enables having a more uniform distribution of heat, which will enhance melting of the adhesive.
- According to an exemplary embodiment of the present invention, the heating portion comprises at least two walls facing each other. By the two walls facing each other is meant that the surface of each wall which is intended to be heated has a respective surface normal, and the two respective surface normals intersect each other. This also enables having a more uniform distribution of heat, which enhances the melting of the adhesive.
- According to an exemplary embodiment of the present invention, the heating portion comprises a user protection cover made of a plastic material. This is advantageous to prevent the user from burning while using the tool.
- According to a second aspect of the present invention, a method for extending eyelashes using a tool according to the first aspect of the present invention is provided. The method comprises the steps of:
- providing an extension element provided with an adhesive,
- separating at least one eyelash to be extended from adjacent eyelashes using the first and the second leg portions of said tool
- heating the adhesive attached to the extension element using said heating portion, such that said adhesive melts,
- mounting the extension element to one of the eyelashes which has been separated out by holding the extension element against the eyelash to be extended,
- fastening the extension element to the eyelash by adhering and solidification of said adhesive.
- In relation to this invention the term adhesive include compositions that may act as bonding between the eyelash and the extension element, e.g. hot melts and waxes.
- The method according to the second aspect of the present invention is a general method which may be performed using other tools than a tool according to the first aspect of the present invention.
- The extension element may be any element suitable for attaching to an eyelash. Typically, the extension element will be an artificial eyelash, but other types of extension elements are also conceivable, such as for example feathers or other decorations.
- The adhesive is an adhesive composition which may be heated such that it melts. The adhesive composition may comprise a plurality of different components. The adhesive may be provided on the extension element for example by dipping a portion of the extension element in the adhesive while it is in its melted form. The adhesive is then allowed to solidify e.g. while it cools, whereafter a desired amount of adhesive is attached to the extension element. Preferably only a portion of the extension element is covered with the adhesive, but in some embodiments the whole extension element may be covered.
- By separating at least one eyelash to be extended from adjacent eyelashes is meant that the eyelash to be extended should not be in contact with the adjacent eyelashes. This is to avoid adhering the extension element to the adjacent eyelashes when mounting it to the eyelash to be extended.
- The step of heating the adhesive attached to the extension element using said heating portion, such that said adhesive melts, is suitably performed by gripping the extension element using a tool, such as a tweezer, and holding the extension element against or above the heating portion. The temperature of the heating portion is suitably adapted to the melting point of the adhesive, to enable melting of the adhesive.
- When mounting the extension element to one of the eyelashes which has been separated out, the extension element is suitably still gripped with tool such as a tweezer. Once the step of fastening the extension element by solidifying of said adhesive has been performed, the extension element may be released from the tweezer. Due to the solidifying which results in a bonding of the adhesive, the extension element will then stay attached to the eyelash to be extended.
- According to an exemplary embodiment of the second aspect of the present invention, the extension element comprises at least one artificial eyelash. In some exemplary embodiments, the extension element may comprise a strand or a bundle of artificial eyelashes. The artificial eyelashes may suitably be made of a synthetic material, or they may be made of hair. Other types of extension elements are also conceivable, such as feathers or other decorations of different materials and shapes.
- According to an exemplary embodiment of the second aspect of the present invention, the adhesive is a composition selected from a group comprising: hot melts, low temperature melting hotmelts waxes such as microcrystalline waxes and combinations thereof. For hot melts including low temperature melting hotmelts (such as ethylene vinyl acetate polymer) and micro crystalline waxes the bond to the lash is established upon solidification. Low temperature melting hotmelts and waxes are advantageous as they melt to liquid form at temperatures which is safe to use close to the human eye.
- According to an exemplary embodiment of the second aspect of the present invention, said composition also comprises:
- a) one or more pigments, wherein preferably said one or more pigments is carbon black.
- Using one or more pigments in the composition may be beneficial to reduce the visibility of the adhesive, such that the extension looks more natural.
- These and other features and advantages of the present invention will in the following be further clarified with reference to the appended drawings showing different embodiments of the present invention.
