The panels can be made from a supple magnetic natural or synthetic elastomer such as rubber, plastic or silicone, or they can contain rigid magnetic elements e.g. of ferrite joined by strips of a supple material lying parallel to the container's axis.

Description

-1- The present invention relates to a receptacle for brushes and

  possibly thinner, combined in a way

  removable or integral with a box of product to be applied.

  Most boxes of product to apply (paint type) do not have a reservoir to hold the brush and when you stop painting momentarily, it is customary to place it on its top in unstable equilibrium with

possible paint grout.

  They also do not have a diluent tank to soak the brush (es) to prevent them

  dry during a prolonged stopping of painting.

  They also do not have a separate anti-drip rim from the upper edge, when the brush drips off, causing paint stains on the closing edge of the

  the box which when drying prevents the lid from closing properly.

  There are two patents (n 2693885 and n WO93 / 02871) concerning a brush holder dealing with these problems.

  Despite everything, it has the following drawbacks: 20 - it is necessary to remove the cover and leave the box open to hang it on its upper edge. - the location of this in the upper position of the box, with a brush inside can cause

  overturning of the assembly when the box is small and almost empty.

  - during a prolonged stop of the application, it is necessary to close the box with its cover to avoid

  the product does not dry out or deteriorate. This raises the question of how to store it if you want to leave the brush to soak inside with thinner.

  The proposed receptacle solves these problems. This is of a shape adapted to contain standing indifferently at least one brush of rectangular shape

  (flat) or circular (round) and possibly thinner. It is produced in two fixing methods.

  - With a removable and independent fixing of the closure system of the product box and intended to be applied to the outer wall of metal boxes of ferrous type40 of existing products, having rounded or straight shapes, -2- of any size, by by means of magnetic fasteners associated with a rubber support or

flexible synthetic.

  - With an integral and independent fixing of the closure system, of a box which can be held by one hand and intended to receive in limited quantity the product to

  apply from larger packaging.

  More generally, the invention relates to a device intended to hold in position at least one brush of flat or round shape on a box of product to be applied, of the type consisting of a receptacle having at least one flared recess of depth corresponding substantially to the maximum height of the bristles including the crimping ring and possibly containing at its bottom thinner, and means

  holding on the container or box.

  The brush receptacle consisting of a tray comprising a flat bottom, a flat rear face, a front face and two rounded and flared side faces. Its front face is provided over its entire length with an upper edge projecting towards the inside to form a drainer and which has in its middle part a concave zone intended to hold the base of the handle of a round brush in position, and the rest of the compartment being conformable to receive a flat brush thus making it possible to group in the same volume two

recesses.

  According to other particularities: The container further comprises internally at its front face and symmetrically to the axis of the concavity of the border two vertical ribs going towards the bottom; the base of these is extended by two straight ribs of fine thickness perpendicular to the bottom and arranged in a V on it. The container has a flat strip arranged on the upper edge

  from the back and tilted inward.

  The container has on the rear part of its rear face a vertically centered shoulder of thickness corresponding substantially to the width of the upper rear strip and its

  rear face has a concave face over its entire height.

  The means for holding the container consist of a flexible magnetic support composed of a set of magnetic rubber or ferrite strips, arranged vertically with respect to the container, separated from each other by a small space and supported on one side a thin and flexible sheet, for example rubber or synthetic material. Ensemble5 being fixed by the opposite face of the thin sheet, vertically in the middle, on the concave rear face of the shoulder of the tray thus defining a fixed central magnetic zone and on either side thereof two others flexible magnetic lateral zones from the two lines of articulation of the support, to be removably attached to the external faces of rounded or straight shape of containers or cans of soft iron of product to be applied, and

  which can thus be positioned at the bottom of these or these

  ci so that the bottom of the tank is in contact with their support plane. According to the other embodiment, the holding means are fastening means integral with a box intended to receive a limited quantity of the product to be applied and to be held by one hand.20 Said box and its cover are cylindrical and watertight, for example made of metal or plastic. It has inside its upper part a drip rim executed by crimping or molding or coming from an interior metal cover with easy finger opening that is on The fixing of the cover is screwed by hand like a bayonet (twist-off) or screw. The bin is glued or

  welded vertically to the outside along and below it so that the outside face of its bottom is in contact with the support plane of the box. 30 A description of the embodiment of: RECEPTACLE WITH REMOVABLE FIXING

  will be made with reference to the accompanying drawings. Figure 1 is a front view of the receptacle and partial section of its bottom with example of attachment to a wall35 straight box (4). Figure 2 is a top view of the receptacle with example of attachment to a rounded wall of a circular box (3). Figure 3 is a sectional view AA of the receptacle with example of attachment to a rounded wall of a circular box (3) .40 Referring to Figures 1,2, and 3, the receptacle is made of two parts and comprises: -a brush tray (1) - a magnetic support (2) The brush tray (1) is made of plastic or derivatives, rigid with walls (la), (lb), (lc), (li), (lj), define with a bottom (ld) a compartment (le) of depth corresponding substantially to the maximum length of the bristles including the crimping ring of a flat or round brush and

  possibly containing thinner.

  The two types of brushes are supported by their bristles on the two ribs (11), and the bottom (ld) .The base of the flat brush fits in the space between (lc), (lb), (lj) and that of the round brush in the concave space of the border (li)

and from the back (lc).

  This bin has a rounded envelope on its front face (la), and its two sides (lb), a flat rear face (lc) and a flat bottom (ld). Its vertical shape is conical and its opening flared (lp), inclined forming an angle x with respect to the horizontal

  to facilitate the introduction and removal of the brush.

  Coming with the envelope, the following elements are assembled: -A front upper border (li) with two cheeks (lj), of the same thickness as the envelope and projecting towards the inside of the tank to form a drip tray and presenting in its middle part a concave zone intended to hold the round brush. This border is supported by its two cheeks (lj) on the upper part of the two ribs (lh). The inner edges of this border (li), (lj), and of the two ribs (lh) serve as a scraper to drain the brush when it is

remove with a rotary motion.

  -Two vertical ribs (lh) arranged inside the front face (la) and symmetrically to the axis of the concavity of the border (li) and going towards the bottom (ld) ending in: - Two thin straight internal ribs (ll) arranged in V on the bottom (ld) penetrating into the

  brushes to avoid slipping.

  -A flat strip (lk) of the same thickness as the envelope placed on the upper edge of the flat rear face (lc),

  of width equal to the depth of the shoulder (1f) and 40 inclined towards the inside of the tank.

  -5- This facilitates the flow of the product inside the tank during the introduction of the brush and protects against

  possible grout between box and tray.

  -A shoulder (lf) centered vertically on the back of the rear face (lc) of thickness corresponding substantially to the width of the strip (lk) and having on its rear part a concave face (lg) over its entire height. has a radius of curvature corresponding substantially to that of cylindrical cans of current existing products and is

  intended for fixing the flexible magnetic support (2).

  A flexible magnetic support (2) with a surface substantially equivalent to that of the flat rear face (lc) constituting the holding means is composed of: - a set of magnetic rubber strips or ferrites (2f) arranged vertically with respect to the tray separated between them by a small space (2i) and supported on one side: - of a thin and flexible sheet of rubber or synthetic (2a) The whole being fixed by gluing, welding, riveting or other means by the opposite side of the sheet (2a), vertically in the middle on the concave rear face (lg) of the shoulder (if) of the container, thus defining a fixed central magnetic zone (2g) and two flexible lateral magnetic zones (2b) distributed also on either side of these from the two articulation lines (2k) of the support (2). The central area (2g) represents an area corresponding to that of about three rows of strips. These follow the shape of the concave face (lg) and have a surface that perfectly matches the rounded shape of the wall of the circular boxes of common products (3). For straight-shaped boxes (4), the distance (2m) of the central strip from the wall represents a negligible loss of attractive force35 compared to that of all of the strips. flexible lateral zones (2b) can approach or move away from one another by the spacing (2i) while being articulated freely by means of the flexible sheet (2a) to thus marry perfectly the

  different diameters of round or straight boxes.

  The articulation provided to the strips allows those -

  ci an optimum orientation of their magnetic lines of force to the wall of the box to obtain a maximum attractive force.5 The manufacture of this flexible magnetic support (2) could be obtained in another way; for example by using only a magnetic rubber band and practicing by machining (by milling cutters or laser) blind grooves at regular intervals for the spacings (2i) taking care to leave a thin rubber backdrop thus replacing Another flexible method of manufacturing the support could consist of an overall magnetic rubber molding representing strips (2f) and the flexible sheet (2a). One could also consider using, moreover, round section ferrites. According to a second embodiment of magnetic attachment, the flexible magnetic support (2) could be eliminated by limiting itself to a central attachment (2g). The rigid shoulder (lf) could be replaced or supplemented by a semi-rigid attached support and receive ferrites making it possible to be slightly mobile capable of presenting optimal positions of magnetization to the rounded or straight wall of the boxes. ensure good fixing and avoid pivoting of the tank during a force exerted on the side thereof, especially sensitive on a straight wall, this requires specially powerful ferrites taking into account the very limited contact surface limited to the area central (2g). This embodiment remains possible, however, but is not the preferred solution of the invention. More generally, the manufacture of a flexible magnetic support as described above with its variants may find other applications, such as fixing decorative objects, flowerpots, or other, on straight and specially rounded metal surfaces of ferrous type such as bicycle frame, lectern or hospital bed frame, barrels, gas cylinder for camping etc. -7- According to a second embodiment, a

  DESCRIPTION OF THE RECEPTACLE WITH SOLIDARITY FIXING

  will be carried out with reference to FIG. 4.

  The receptacle adopted for this method of attachment consists of the plastic container (1) without flexible magnetic support (2). The tray (1) is fixed integrally to a box which can be held by one hand and intended to receive a quantity

  limited product to apply (7g).

  The cylindrical box (7), and its cover (7a) are sealed and can be made of metal or plastic. The upper part of the box has an internal drip edge (7b) set back from the upper edge, resulting from a crimping or molding or coming from an interior metal cover with easy finger opening (7c) which has The cover (7a) is made of metal and screwed by hand, bayonet type (twist-off) plasticized inside or screwed with

seal.

  The tray is glued or welded along the outside of the box to receive the brush (es) (7d) (7e) and the thinner (7f) .This rests on its concave vertical face (lg) of its shoulder (if) and is positioned vertically at the bottom of the box (7) so that the outside face of its bottom (ld) is in contact with the support plane (5) of the box (7) to ensure good stability

of the box-tray-brush assembly.

  In other variant embodiments, the type of box used may be of different shapes (oval, square,

  rectangular or multiple-sided) with a penny-type cover, covering, fitting or tilting in plastic or metal without departing from the invention.

  The box with its associated tray can be used for the applications of: paint, varnish, lacquers, glues, waxes, wood treatment products, wood and metal strippers, sealer, anti-rust, grease, etc ... And by extension35 in cases where you want to use a product in limited quantity requiring a brush with possibly thinner
