Description

Improved brushes

technical field

The present invention relates to an improved brush.

Background technique

To date, different types of brushes are known which differ in shape, size and type of material of which they are composed, which vary depending on the field of application and the desired final aesthetic result.

In general, all brushes have a grip body that is especially adapted to be held and held in the hand by the user.

The gripping body, generally elongated, includes a distal end with a suitable opening that accommodates an applicator body adapted to remove the product and apply it to the work surface.

"Product" in this context refers to any material, such as powders, creams and liquids, that is applied, painted on and applied with a brush in cosmetics, art, food and industry.

Similarly, "working surface" refers to any surface suitable for being applied and/or covered by the aforementioned products, for example, a portion of human skin, an article of manufacture, a building surface, food, etc.

Specifically, the brushing body includes a tuft of bristles, a part of which is inserted into the opening so as to be surrounded by the end of the gripping body, and fixed on the end of the gripping body by glue or other fixing substances and methods.

The part of the bristle protruding from the opening, depending on the shape of the opening itself and the insertion technique, provides different configurations of the brushing body according to the type of brush.

In addition to the shape, the hardness of the brush body is also different, determined by the type, length and diameter of the bristles, and varies according to the characteristics of the product to be used and the desired aesthetic effect.

In the present case, a hard applicator is suitable for applying dense cream products, whereas a soft applicator is suitable for low density products such as powders, bronzing powders, and blushes.

However, heretofore known brushes have a uniformly stiff application body in which different types of bristles are mixed together to provide a uniform texture.

These known brushes have some disadvantages related to the different types of applications required; this means that whenever a different aesthetic effect is desired, the type of brush has to be changed.

For example, in the case of a creamy product, it is necessary to apply with a brush with a strong and elastic applicator body, and to obtain the shading effect subsequently, another brush with a softer applicator body is required.

Therefore, in order to obtain different aesthetic effects, it is necessary to use multiple brushes, making the application and application of the product quite complicated.

Therefore, there is a need to apply operations to known products that simplify and speed up without giving up a satisfactory end result.

Contents of the invention

The main object of the present invention is to provide a brush with applicator bodies of parts of different hardness and texture, which enables the smearing and application operations of products in a fast and precise manner.

Another object of the present invention is to provide a brush that simplifies and speeds up the operation of smearing and applying products, thereby achieving different aesthetic effects by using a single brush.

Another object of the present invention is to provide a brush capable of overcoming the above-mentioned disadvantages of the prior art within the scope of a simple, rational, easy, effective use and affordable solution.

The above objects are achieved by an improved brush having the features of claim 1 .

Detailed ways

With particular reference to these figures, indicated generally with reference number 1 is an improved brush.

The brush 1 comprises a housing seat 3 of an applicator body 4 which in turn comprises first tufts of bristles 6 suitable for applying the product on the working surface.

The brush 1 comprises a gripping body 2 associated with a housing seat 3 .

In particular, the brush 1 comprises an enlarged end 5 of the ring nut type with an opening defining the housing seat 3 .

An enlarged end 5 , ie a ring nut, is associated with the gripping body 2 . In this respect it is worth noting in particular that the brush 1 can be used with a commercially available assembly, that is to say with a gripping body 2 associated with a ring nut 5, or in separate form, for example in the form of a kit, several of which The ring nuts 5 are connected to the gripping bodies 2 one at a time.

Alternatively, the grip body 2 comprises an opening defining the housing seat 3 . As shown, the gripping body 2 has an elongated shape which widens at the end 5 to define a frustum.

However, there are also alternative embodiments in which the gripping body 2 has a squat shape or configuration in order to improve ergonomics and the user's grip, and a different configuration of the enlarged end 5 cannot be excluded, e.g. cylindrical , oval or frustoconical, but with a wider attachment towards the grip body 2 and a narrower attachment towards the housing seat 3 .

With reference to the particular embodiment shown in the figures, the housing seat 3 has an approximately frusto-conical shape.

However, there are also other embodiments in which the housing seat 3 has a different shape, eg triangular, square or irregular.

The applicator body 4 has dimensions adapted to fit in the housing seat 3 and in turn comprises a first tuft of bristles 6 adapted to apply the product to the work surface.

The first tufts of bristles 6 define the shape of the applicator body 4, which, as shown, can have different shapes depending on the application.

For example, FIG. 1 shows a first embodiment of a brush 1 in which the applicator body 4 has an approximately hemispherical cap-like shape.

In contrast, FIG. 2 shows a second embodiment of the brush 1 in which the applicator body 4 has a convex configuration.

In detail, the first bristle tufts 6 are suitable for applying, brushing and spreading products on the work surface.

With regard to the cosmetic industry in particular, the term "user" refers to the person who intends to apply the cosmetic product, not necessarily the same person who uses the brush 1 .

For example, the brush 1 of the present invention can be used to apply, brush and apply powder, blush and other types of skin care products on a part of a person's skin.

Alternatively, the brushes of the present invention can be used in the food industry, for example for applying, brushing and applying sauces to food.

Likewise, this brush can be used to apply, brush and apply paint to walls. However, other uses cannot be excluded for those mentioned above.

According to the invention, the applicator body 4 comprises at least one element 7a of predetermined hardness suitable for applying the product to the working surface and defining at least one portion 7 of different texture with respect to the first tuft of bristles 6 .

Preferably, the element 7a of predetermined stiffness comprises at least a second tuft of bristles 7b defining a portion 7 of different texture.

In the context of this description, "an element with a predetermined hardness" refers to a one-piece element that fits within the first bristle bundle 6 and is intended to define inside the applicator body 4 a different hardness specific to the first bristle bundle 6 . The portion 7 of the texture, and the second bristle tuft 7b having a smaller size than the first bristle tuft 6 and having a different hardness relative to the first bristle tuft 6, correspondingly define Part 7 with a different texture.

This means that the term "hardness" should be understood with reference to the overall texture and compactness of the applicator body 4 .

In other words, the applicator body 4 has a resistance against the elastic deformability uniformly distributed inside it, and during use of the brush 1 there is an element 7a or a second bristle bundle 7b with a predetermined hardness, allowing to have the applicator body 4 A specific portion which has a defined different texture relative to the first tuft 6 of bristles.

Advantageously, the texture of the aforementioned portion is defined by an element 7 a of predetermined hardness or by a second bristle tuft 7 b , which may be larger or smaller than the first bristle tuft 6 .

In particular, the presence of elements 7a or of second bristle tufts 7b with a predetermined hardness allows application of the product in a sharp and neat manner, while at the same time adjusting the final aesthetic effect by using a single brush 1 .

Advantageously, the first bristle tufts 6 are made of a first type of material and the element 7a of predetermined hardness is made of a second type of material different from the first type.

At the same time, in the case where the portion 7 with a different texture is defined by the second bristle bundle 7b, the first bristle bundle 6 is made of a first type of material and the second bristle bundle itself is made of a second type of material different from the first type of material. material.

The first bristle tufts 6 are made of a material of animal and/or vegetable and/or synthetic origin.

For example, the first bristle tufts 6 may be made of natural hair traditionally used in the manufacture of brushes, such as mink, horsehair, goat, pig, squirrel vair, etc. as non-limiting examples.

Alternatively, the first bristle tufts 6 may be made of synthetic material, such as non-limiting examples: polyamide, polybutylene terephthalate, polyolefin, polyester, composite material, silicone, etc.

Advantageously, the element 7a having a predetermined hardness is made of a polymer material.

The aforementioned polymer material is selected from polybutene, terephthalate, silicone, polyurethane, polyolefin, polyamide, composite material, biopolymer, elastomer and copolymers thereof.

Similarly, the second bristle tuft 7b is made of a polymer material selected from the above materials.

Therefore, an alternative embodiment cannot be excluded in which the first bristle tuft 6 is made of a first type of material and the element 7a with a predetermined hardness is made of a second type of material identical to the first type of material; this means, for example, The possibility cannot be ruled out that both the first bristle tuft 6 and the element 7a having a predetermined hardness are made of a polymer material.

In this case, the different texture of the first bristle tuft 6 and the element 7a with predetermined hardness is determined by the thickness of the latter; this means that, compared with the conventional mean diameter of the bristle tuft 6, although The material of 6 and the element 7a of predetermined hardness are the same, but the thickness and size of the element 7a of predetermined hardness ensure that a bristle with a different texture and density (i.e. smaller or larger) relative to the first bristle tuft 6 is defined. part.

Similarly, where the portion 7 with a different texture is defined by the second tuft 7b, the first tuft 6 is made of a first type of material and the second tuft itself is made of a second tuft of the same material as the first type. type material.

In this case, the different textures of the first bristle tufts 6 and the second bristle tufts 7 b are determined by the greater density of the second bristle tufts 7 b relative to the first bristle tufts 6 .

Optionally, the different textures of the first bristle tufts 6 and the second bristle tufts 7b are determined by the wider resistance portion of the second bristle 7b than the resistance portion of the first bristle 6 . This means that, compared to the smaller mean diameter of the first bristles 6, although the material from which the first bristle tufts 6 and the second bristle tufts 7b are composed is the same, relative to the smaller or larger mean diameters of the second bristles 7b, The latter ensures that portions 7 of different texture (ie smaller or larger) with respect to the first tufts of bristles 6 are defined.

However, other embodiments are not excluded in which the first bristle tuft 6 and the element 7a of predetermined hardness or the second bristle tuft 7b can be made of materials of animal and/or vegetable and/or synthetic origin; analogously to what has been described above, In this case, the thickness and size of the element 7a with a predetermined hardness or the resistive portion and density of the second bristle tuft 7b also ensures that a portion 7 with a different texture is defined, i.e. larger or thicker with respect to the first bristle tuft 6. Small.

Referring specifically to FIGS. 1 , 2 , 3 , 4 and 5 , the applicator body 4 includes only one element 7 a of predetermined hardness fitted in the first bristle bundle 6 .

The element 7 a with a predetermined hardness can have different positions within the applicator body 4 .

For example, it can be arranged transversely on the first bristle tuft 6 ( FIGS. 1 and 2 ) or it can be arranged centrally with respect to the first bristle tuft 6 ( FIGS. 3 , 4 and 5 ).

Meanwhile, the member 7a having a predetermined hardness may have different shapes, thicknesses and lengths according to user's needs.

For example, the element 7 a of predetermined hardness may have the same length as the first bristle tuft 6 ; alternatively, the element 7 a of predetermined hardness may be shorter or longer than the first bristle tuft 6 .

Similarly, shape and thickness vary according to the particular type of material used or the particular field of application.

As shown in FIGS. 1 , 2 , 3 , 4 , an element 7 a of predetermined hardness has an approximate shape of a sheet and is associated with the housing seat 3 at one end.

Alternatively, FIG. 5 shows a fifth embodiment of a single element 7 a of predetermined hardness, having a cylindrical configuration arranged in the center of the applicator body 4 .

However, alternative solutions cannot be ruled out, in which the elements 7a with a predetermined stiffness have different shapes (triangle, star, rhombus, etc.) and are not necessarily laminar or cylindrical.

Optionally, Fig. 6, 7, 8 and 9 show other embodiments, wherein the applicator body 4 comprises a plurality of elements 7a with a predetermined hardness, and a plurality of elements 7a with a predetermined hardness are at least partially assembled in the housing seat 3 in.

Expediently, at least one of the elements 7a having a predetermined hardness is arranged centrally in the applicator body 4 .

In this regard, FIG. 6 shows a sixth embodiment in which the applicator body 4 comprises a plurality of elements 7a of predetermined hardness which are aligned and centrally aligned with the first tuft of bristles 6. Arrange it.

However, alternative embodiments in which at least one element 7 a of predetermined hardness is arranged transversely to the applicator body 4 cannot be excluded.

Advantageously, the elements 7a of predetermined hardness define a plurality of portions 7 having a different texture with respect to the first bristle tufts 6; this means that different elements 7a of predetermined hardness can be grouped and arranged next to each other to define groups , the grouping can be arranged at different positions inside the applicator body 4 .

For example, FIG. 7 shows a seventh embodiment in which elements 7a of predetermined stiffness are arranged adjacent to each other to define portions 7 of different texture, i.e. larger or smaller centrally placed with respect to the first bristle tuft 6. part. Alternatively, FIG. 8 shows an eighth embodiment, in which elements 7 a of predetermined hardness are arranged next to each other to form two groupings arranged transversely to the applicator body 4 .

However, the elements 7 a having a predetermined hardness may be separated from each other within the applicator body 4 ; this means that the latter may appear dispersedly inside the applicator body 4 . In fact, FIG. 9 shows a ninth embodiment in which the applicator body 4 has a plurality of elements 7 a of predetermined hardness having different positions inside the first bristle tuft 6 .

In this embodiment, each element 7a having a predetermined hardness has a circular cross-section; however, alternative embodiments in which each element 7a having a predetermined hardness has a square, triangular, diamond-shaped cross-section, etc. cannot be excluded.

Meanwhile, Figures 10-18 show an alternative embodiment in which the portion 7 with a different texture is defined by a second bristle tuft 7b. Referring to FIGS. 10 , 11 , 12 and 13 , the applicator body 4 comprises only one portion 7 with a different texture, which is defined by a second tuft of bristles 7 b mounted inside the first tuft of bristles 6 .

Similar to the element 7 a having a predetermined hardness, the second bristle bundle 7 b can also have a different position within the application body 4 .

For example, it can be arranged transversely on the first bristle tuft 6 ( FIGS. 10 , 11 and 12 ) or it can be arranged centrally with respect to the first bristle tuft 6 ( FIGS. 14 , 15 and 16 ).

Preferably, the second bristle tuft 7b may have the same length as the first bristle tuft 6 ; alternatively, the second bristle tuft 7b may be shorter or longer than the first bristle tuft 6 .

However, the discussion regarding the shape and thickness of the element 7a having a predetermined hardness is completely analogous to the discussion regarding the corresponding shape and thickness of the second bristle tuft 7b.

Figures 10-13 show an embodiment in which the second bristle tufts 7b have an approximate laminar shape and each second bristle tuft 7b is associated with the housing seat 3 at one end.

Alternatively, FIGS. 13 and 14 show an alternative embodiment in which the second bristle tuft 7 b has a cylindrical shape and is arranged centrally on the applicator body 4 .

Finally, Figures 15-18 show a plurality of second bristle tufts 7b dispersed within the applicator body 4, eg (Figure 15), arranged laterally to the first bristle tufts 6 (Figure 17), or spaced apart from each other ( FIG. 18 ) is arranged in the center of the first bristle bundle 6 ( FIG. 16 ).

Before describing in detail the operation of the present invention and its specific structural aspects, it should be noted that the element 7a, or alternatively the second bristle bundle 7b, with a predetermined hardness, Portions of different textures and densities of the bundle 6 are repeatable within the application body 4 and can be placed in one or more precise and predetermined positions.

Adding to this the differently textured portion 7 achieved by the second bristle bundle 7 b makes it possible to obtain quite different effects than those described in patent documents FR 663 618 and FR 2 996 738 .

In particular, the technical effect associated with the presence of portions 7 with different textures allows a corresponding variation in the aesthetic effect obtainable on the work surface.

Furthermore, the invention allows optimizing the supply of materials constituting the portion 7 with a different texture, especially when the latter is made of the same material as the first tuft of bristles 6 .

The operation of the present invention is as follows.

By holding the gripping body 2, holding the brush 1 close to the product to be used, the first tuft of bristles 6 is placed in contact with the product to be used, so that the desired amount of product can be picked up.

The latter is then applied to the work surface and, if an even application of the product is desired, can be applied, spread and spread with the first bristle tufts 6 by pressing the brush 1 strongly on the work surface and manipulating (shade) the product.

If the product is required to be applied in a neat and clean manner, or to be strongly marked on the work surface in order to obtain a specific aesthetic effect, it is possible to use a differently textured portion 7 of the applicator body 4, which consists of elements with a predetermined hardness. 7a or is defined by a plurality of second bristle tufts 7b by pressing and handling on the working surface.

It has actually been determined that the described invention achieves its intended ends.

It is highlighted by the fact that a specific method of providing at least one element with a predetermined hardness or at least a second bristle bundle allows correspondingly variable aesthetic effects to be obtained on the working surface by using a single brush.

Furthermore, providing a differently textured portion made of the same material within the priming body may allow optimization of the supply of construction material.
