Description

THERMOFUSIBLE BINDER POWDER RESERVOIR COMPRISING A TENDENT FLEXIBLE GRID

FIELD OF THE INVENTION

The invention relates to a device for producing a deposit of hot melt binder powder.

The invention more particularly relates to a device for depositing a heat-fusible binder powder in a simple manner and in controlled quantities, on a horizontal surface, for example a textile surface deposited on a table, which surface will then be covered by another rigid material or flexible, for example another textile or a cardboard, the two materials to be thus assembled by these heat sealing techniques.

STATE OF THE ART

The use of hot melt powder for gluing or joining two surfaces, such as for example a textile substrate on another textile substrate, is well known. The melting of the hot-melt powder is effected by external thermal input, and the sizing of a substrate on another substrate, and obtained by pressure during the melting of the hot-melt material and possible maintenance of the contact pressure between the two surfaces. to assemble, during the cooling phase.

Other techniques are also available to assemble two textiles. Thus the use of a thin binder hot melt film made from the same materials as the powder mentioned above is also possible. The hot melt film is then positioned between the two substrates to be assembled. The materials constituting the powder or the hot-melt film are polymers whose primary characteristic is to develop, in the molten state, sufficient bonding forces on the substrates considered, while having the capacity to withstand the environmental conditions likely to be encountered in the implementation and use, for example textiles, that is to say, to keep washing, and therefore to exhibit resistance to hydrolysis and a minimum of temperature, as well as to present a good resistance to the usual solvents used in the dry cleaning of these same, for example textiles.

In addition, the textiles to be assembled must preserve, once assembled, a certain flexibility, also called "hand", and not appear as "cardboard". The hot-melt powder is thus preferred to the hot-melt film, insofar as the amount deposited can be easily adapted, whereas for the binder hot-melt film, it will be necessary to choose films of different thicknesses and possibly perforated or notched films also to to preserve a certain degree of breathability for the fabrics thus assembled, this problem of loss of breathability not being posed in the case of a deposit of hot-melt powder.

The constituent materials of these hot-melt powders or hot-melt films are in general polar polymers, such as acrylic acid ethylenes, maleic anhydride • ethers, ethylene vinyl acetates, and preferentially for reasons of heat resistance, polyamides and co-polyamides. and polyesters and co-polyesters.

For industrial applications, heat input can be via heated rollers, infrared booms, or any other technique. The pressure medium is General in- one nip roller system, or ^mobile carpet bringing the necessary pressure during the cooling phase.

For mainstream applications, a dressmaker's iron will act both as a means of heat input and as a means of pressure.

If the powder deposition systems are perfectly controlled in the case of industrial applications, for example in the case of vibratory support systems distributing, over the entire surface to be treated, the hot-melt powder, with control of amplitudes and vibratory frequencies, there is no equivalent system and therefore simple devices, especially intended for the general public.

Sizing systems by hot melt material for the general public mainly rely on binding hot melt films, but has the drawbacks previously explained. In addition, it is necessary to cut these hot melt films to the desired dimensions, which is complicated. Finally, this practice naturally leads to losses for a supply, the binder-hot melt film, which is generally expensive.

Devices for dispensing products in powders, for example sugar, salt, condiments, are somehow dusting devices, which do not require to provide such uniformity of deposit.

Such products are generally distributed by perforated grids, coming to fit on their container, without worry of true regular distribution of this powder on a surface. In particular the regularity of distribution is not critical, and hence neither the density of apertures per unit area nor the size of the distribution aperture are decisive factors.

Devices for dispensing powdered food products or other such as sugar, salts, condiments, are described in the state of the art.

A first document (US 2,717,723) is intended to improve the pellet distributor architecture and more particularly, the distribution grid.

This improved pellet dispenser is designed to be incorporable and adaptable to existing dispensing devices of such products. The improved dispenser comprises a granule container, a closing cap, female type, provided with an internal thread cooperating with an external thread of the wall of the container and the distribution grid. This distribution grid is a woven wire mesh, having the convex shape of an inverted cone, provided at its end with an outer flat annular flange, bearing on the edge of the open end of the container on which this mesh is fixed. For the realization of the inverted cone-shaped curved distribution grid, the use of wire having a rough surface state is recommended, this surface state being able to promote the destructuring of the agglomerates formed in the storage container.

Another document (US Pat. No. 2,549,977) describes a device for closing a container filled with powder. This device comprises:

• a cover of elastic material (rubber) in the shape of a hollow dome, constituting a chamber filled of air that can be compressed. This chamber behaves like a pump blowing air into the container by pressing on the dome and

• a tubular outlet duct of the _. fluidized powder by blown air.

This closure device is separated from the powder of the container by a gas fabric membrane allowing the passage of air from the dome into the container. This pressurized air passes through the stored powder and drives it mechanically towards the outside of the container through the tubular outlet duct.

This gas fabric is made of a woven fabric of multi-stranded son twisted together, having a rather rough surface condition, which is caused simultaneously by the ends of. fibers used to form the wire and also by the torsion effect given to the strands to assemble them in a single thread.

Another document (US 3,469,748) describes a closure device for a container-dispenser of powdery products, the closure device consisting of:

• a monocomponent distributor of flexible polymer material formed of a multiperforated circular plate for the distribution of powdery products and a ring-shaped perimetric seal, integral with the plate, whose section is an inverted U, allowing the overlap from the edge of the open end of the container shell.

• An outer cap made of a rigid material having a shape adapted to the unibody distributor so that the plug, once in place, is in contact with the upper part of the inverted U-section perimeter seal, all by fitting in the internal free space of said diametral ^• perimeter seal.

Thus, the dispensing function of the powdery products is provided by the dispenser which is a perforated circular panel whose perforations in limited number, leads to a low perforation density and cause a distribution of the powdery products, according to distribution lines separated from each other. other and equal in number to the number of the perforations, when the dispenser-container is in translation movement, or as separate conical heap ^'from each other when the movement of the dispenser only involves shaking it in a reciprocating movement, and -ve vertical.

Thus, a first way of developing a device for dispensing powdery materials should be to use a simple perforated plate, inspired by the principle ¹ of a salt cellar. However, the distribution performance results are not conclusive. Indeed, the density expressed in gram of a hot melt powder binder per m ² of substrate, and obtained after the flow of the hot-melt powder in this type of salt-type device does not comply with the need, that is, that is, to have a small continuous powder thickness on the surface to be coated, to have uniformity of deposit and to have the maximum surface covered without void areas. Because too much hot melt powder causes risks of loss of "hand-textile" for the textile thus glued, which is manifested by a cardboardy touch of the glued textile zone.

SUMMARY OF THE INVENTION Therefore, there is a need for the creation of a device for producing a controlled and regular deposit of hot melt binder powder, easily usable:

• by the general public, for example by a seamstress trying to assemble two textiles one on the other, or more specifically, by a person trying to make a hem on a garment in the simplest and safest possible way, or to position a piece on a piece of clothing,

And / or by the textile industry for industrial assemblies of textile parts when the dispensing device is mounted on a vibratory device in a production line, for example.

Therefore, the device according to the invention for producing a binder hot melt powder deposit for assembling two substrates, comprises a container, a stopper, a powder dispensing means and is characterized in that the dispensing means powder contains:

a homogeneous distribution grid, flat, flexible, deformed and stretched by tension between the container and an adapter flange and made from continuous and flexible single-strand yarns by the weaving technique and - an adapter flange provided with a means for fixing said grid on said container.

DETAILED DESCRIPTION OF THE INVENTION

It is indeed to offer a device containing the hot melt powder as would any lost packaging, while providing the user with a means of controlled distribution of the powder to meet the requirement of use is that of applying a quantity of powdered ^hot melt very precise and regularly distributed over the entire surface to be treated.

The device for dispensing a hot-melt powder according to the invention will be better understood thanks to the numerical description of illustrative and non-limiting figures.

Figure 1 shows the assembly of the device (1) being mounted, according to one embodiment.

FIG. 2 represents, in an exploded view, according to FIG. 1, the adaptation flange (3) to the container (2), equipped with a tamper-evident cap (6) and its screw-cap (7). .

Figure 3 shows the assembly of the device (1) being mounted, according to another embodiment.

FIG. 4 represents the bending curve under stress of the homogeneous distribution grid after assembly, according to the invention.

According to FIGS. 1 and 2, the container (2) with a device for applying a thermofusible powder is designed in such a way that it allows the use of an adapter flange (3) acting as a functional intermediate piece .

This adapter flange (3) consists of a cylindrical part, provided at its base with a fixing means on the open end of the cylindrical container, a wide open bottom whose opening diameter can reach the internal diameter. of said collar, obscured by a lid tamper-proof tamper (6). Once the seal is torn off, the opening of the bottom is released to allow the passage of the hot melt binder powder. through the homogeneous distribution grid (9).

The tamper evident seal (6) is torn during the first opening. This cover is incorporated in this adapter flange and is an integral part of the adapter flange. A system of thinning of the circumference of this inviolability indicator (6) makes it possible to separate it easily when traction is exerted by the user pulling on the gripping ring (10) also fixed on this opening control cover and also an integral part of this operculum and the adapter collar.

The adaptation flange (3) is fixed on the container (2), by any fastening means (5) and preferably by a press fitting such as clipping.

The container (2) may be a container of any shape, for example a tube. It can be obtained by any technique, such as, for example, injection or deep drawing. It can be metal, or plastic, depending on the manufacturing technologies considered.

There are indeed standard containers of aerosol metal tube type, having turned edges (11). This type of container is a preferred embodiment, insofar as these containers can be of different sizes and therefore of different capacities, while keeping the same dimensions in opening diameter, and height and diameter of the metal overturning serving as a means of attachment to any type of functional closure. The adapter flange (3) has on its outer cylindrical surface a screw thread (4) for receiving a screw closure cap (7).

The adapter flange (3) is made by injection. The injected plastic material is preferably a polyolefin, but may also be any type of injectable thermoplastic material, having stiffness characteristics, a certain elasticity and a certain ductility, however, allowing easy tearing of the opening indicator (6).

The use of a dispensing means of the hot-melt powder (8) acting as a distributor of the powder in order to be able to deposit it in a uniform and controlled manner on the surface to be treated constitutes the essential of the functionality provided. .

According to the invention, the powder distribution means is in the form of a homogeneous woven grid (9) which is flexible and flat.

This distribution grid (9) used as the main means for performing the homogeneous distribution of the hot melt powder on the substrate to be treated, is indeed particularly important.

The use of a flexible, flat, flexible grid (9) as a means of dispersion and homogeneous distribution of a hot-melt powder, when the container containing it is subjected to vibratory movements, or even when a simple pressure flow of a solid in the form of free flowing powder ready to be ^λ s flow is exerted on the gate appears as an advantageous way. This homogeneous distribution grid (9) is very particular insofar as it has a precise mesh opening, compatible with the particle size distribution, retained for the hot-melt powder. Depending on the type of hot melt powder selected, particularly in terms of particle size and particle size distribution, the configuration of the homogeneous distribution grid is adapted.

The homogeneous distribution grid has a mesh opening before mounting on the container preferably between 50 microns and 250 microns. The value set for the mesh opening is chosen according to the particle size distribution selected for the hot melt powder, in particular for the fraction of the powder having the highest sizes.

Various types of hot melt powders are available, whose particle size distribution curve varies between 0 and 500 microns. Some binding hot-melt powders have particle sizes ranging between 0 and 170 microns for some and between 80 and 500 microns for others, and this, depending on the types of uses that can be made, types of collages and assemblies to be made on substrates which are also specific and which determine the choice of the particle size of the powder. The fines obviously pass through the meshes, but the purpose is not to sieve the hot melt powder, but to operate its homogeneous distribution on the surface to be treated.

This homogeneous distribution grid (9) is also specific insofar as it is made of continuous woven single-strand yarns, making it possible to obtain very high perforation densities and very small perforation intervals. The the

percentage of vacuum for the grid, before mounting, may vary for example between 40% and 60% of the total area.

This homogeneous distribution grid (9) is also specific insofar as the threads constituting it have a non-rough surface state and therefore have very particular properties of sliding with respect to the powder, making it possible to excellent flow of the powder through this grid, in a regular and continuous distribution density, and that it is stretched like a drum skin. This sliding property, which is particularly desired for the continuous single-strand yarns constituting the grid according to the invention, goes against the rough surface sought for yarns constituting the grids of the state of the art, the surface of the yarns which are found on many continuous metal wires or on continuous stranded son assembled by twisting or on stranded or single-stranded son made from textile fibers resulting from carding and stretching of the carded fiber web according to the techniques applied to natural fibers and whose inter-fiber cohesion is obtained at least partly by twisting

In addition, an important factor of performance of the good distribution of the powder by the distribution grid also lies in the fact that the thickness of this grid is small, compared with the size of the particles of ^• hot melt powder, thus allowing to reduce the effects of friction, independently of the coefficients of friction mentioned above, which would restrict the ability of the hot-melt powder to flow through the grid.

The fact that it is son of substantially circular or elliptical section and not other types of section also plays a role. role in obtaining a good flow for the powder, insofar as there is guidance of the substantially spherical particles of hot melt powder, for their passage through the gate (9), which would not be the case for other types of sections which do not present this ^the guide area.

The yarn is effectively a mono-filament, continuous which is a continuous mono-strand, rather than a thread made of discontinuous or continuous multi-strand assembled and twisted.

The fact that it is preferentially synthetic yarns, which can be subjected to tension once formed into a grid by weaving, is also important, because the grid thus stretched, both in the weft and in the warp direction, as can be the string of a racket, causes, for this grid, a certain ability to vibrate when subjected to vibrations resulting from sprinkling movements, also favoring the absence of caking of the hot melt powder and thus its- excellent flow at through the homogeneous distribution grid.

Finally, it is important, to obtain a good distribution, to have the largest distribution area possible with respect to the opening of the container.

This tension of the homogeneous distribution grid (9) is realized during the engagement of the adapter flange on the open upper part (11) of the container body (2), having received the charge of hot-melt powder.

This type of embodiment appears to be preferential because the manufacture of the hot-melt powder dispensing container-distributor incorporating such a distributor in the form of an integrated grid (9) becomes very easily industrializable for productions in large series. It is sufficient to position each of the parts, body of the container (2) filled with hot melt powder, homogeneous distribution grid washer (9), adapter flange (3) equipped with its screw cap (7) pre-mounted on the adaptation flange (3), then exerting a downward pressure force to definitively clip the assembly by performing this predefined tension of the flexible homogeneous distribution grid (9) -

The grid is preferably assembled between the container (2) and the adapter flange (3) by simply forcibly clipping between the male part of the neck (11) of the container (2) and the female part (12) of the flange. adaptation (3) by force fitting, the grid being stretched at a multiplicity of centripetal radiating forces, in this assembly operation. This tension results from the elasticity of the grid and the geometry of the clipping.

The grid (9) is flexible so that it can be deformed and stretched when it is assembled between the container (2) and the adapter flange (3). The radial tension exerted on the flexible grid (9) is uniform, so that each powder distribution device (1) thus produced is expected to have the same behavior with regard to its distributive capacity of the hot-melt powder.

The single-stranded continuous wires used for the production of the homogeneous distribution grid may be chosen from smooth-surfaced flexible metal continuous filaments, carbon fiber-based continuous filaments, and continuous filaments made from polymers. and / or thermoplastic synthetic copolymers belonging in particular to the group consisting of polyamides, polyesters, polyvinyl alcohols, polyolefins, polyurethanes, polystyrenes, polycarbonates, which may or may not be charged.

The homogeneous distribution grid (9) is manufactured from continuous monofilament yarns above diameter of between 50 and 150 microns: it is performed by any known weaving technique.

The homogeneous distribution grid (9) is preferably made from single-stranded yarns of polyamide and polyester. These continuous synthetic yarns are obtained by conventional techniques making it possible to manufacture by extrusion monofilaments which are capable of being subsequently stretched, thermally stabilized or thermally shrunk.

Continuous natural threads such as silk could possibly be used to make such a grid, but with fewer formulation options. ^"Indeed, a synthetic material can be easily made, either in the mass or on the surface to present a coefficient of friction as low as possible.

It is also worth mentioning that the production of a rigid grid, for example made of rigid metal wires, comprising a large quantity of holes per cm ² is expensive and that, moreover, the good properties of friction and sliding of the hot-melt powder on such a rigid grid would be insufficient in contrast to those observed on a flexible grid made from woven mono-son, preferentially synthetic mono-son of very small diameter, thus allowing the excellent dispersion, homogeneous distribution and flow of the powder thermofusible to spread evenly over the surface to be treated. Optionally a removable flexible foam cylinder of the polyurethane type, for example, conceals the opening (13) of the adapter flange (3) once the seal of the opening indicator (6) has been detached, in order to prevent the hot melt powder out of the container when stored in the inverted position. According to FIG. 3, which represents the assembly of the device (1) according to a second embodiment, the container (22) with a hot-melt powder application device is capable of receiving an adapter flange (23) acting as a part functional intermediate, by simple forced adjustment between the cylindrical inner wall of the container (25) and the cylindrical outer wall (26) of the adapter flange (23).

This adapter flange (23) is composed of a cylindrical part having the capacity to fit forcibly into the open end of the cylindrical container, over a minimum of height, an upper base (29) abutting on the open end of the container, and a wide open bottom whose opening diameter can reach the internal diameter of said collar. The adapter flange (23) has this cylindrical opening (24) which will allow the passage of the binder heat-fusible powder through the homogeneous distribution grid (9).

The adapter collar (23) is fixed to the container (22) by any fastening means (25) and preferably by a force-fitting fitting.

The adapter collar (23) may optionally have on its outer cylindrical surface (26) a plurality of fine grooves along a generatrix or peripherals intended to facilitate the attachment of this adapter collar, inside the container (22). by imprisoning the grid of homogeneous distribution (9) between the outer surface (26) of the adapter flange (23) and the inner cylindrical surface (25) of the container (22).

The adapter flange (23) is made by injection. The injected plastic material constituting the adapter flange is preferably a polyolefin, but may also be any type of injectable thermoplastic material, having rigidity characteristics, a certain elasticity allowing the press fit on the container (22).

The grid (9) is flexible so that it can be deformed and tensioned when assembled between the container (22) and the adapter flange (23). The voltage of the homogeneous distribution grid is substantially the same as in the previously described configuration.

The homogeneous distribution grid (9) is of the same type as that described in the previous embodiment.

The container (22) may be a container of any shape, for example a tube. It can be obtained by any technique, such as, for example, injection, extrusion or deep drawing. It can be metal or plastic, depending on the manufacturing technologies considered. It may also be more or less flexible, flat-bottomed or pinch-welded in the case of a flexible tube, and may be opaque or transparent.

The device (1) has a plug (27) closing said device. This plug can be of any type, for example be flexible because made from elastomers and it is then obtained by the injection techniques. He settles on the outer surface of the container (1), and its elasticity and surface adhesion allows it to be held on the container body.

Optionally a removable flexible foam cylinder of the polyurethane type for example occludes the opening (24) of the adapter flange (23) to avoid. the hot melt powder out of the container when stored in the inverted position.

The device (1) is used for deposition and sprinkling of hot-melt binder powder for assembling two flexible or rigid surfaces for the general public.

The container equipped with its hot-melt powder dispensing device is a lost packaging, which is thrown once the hot-melt powder consumed. Advantageously, it is quite possible to spread all the hot-melt powder present in the storage container, without having to leave even a small amount at the bottom of the container.

The hot-melt powder dispensing device associated with and secured to the storage container can also be used industrially. It is then mounted on a vibratory device, and is then advantageously considered as easily exchangeable cartridge, containing a hot melt powder adapted to a specific task, in the case of industrial equipment.

It is indeed easier to change a cartridge, rather than clean the entire machine containing such hot melt powders. The dimensions of the dispensing device and the dimensions of the container are then greater than for a consumer product that must be easy to handle with one hand.

EXAMPLE

Such a device according to FIG. 1, intended to produce a deposition of hot-melt binder powder, is manufactured, according to the invention, from a 100 micron mesh opening grid before assembly. The wires constituting the grid are 100 micron diameter polyamide yarns which create, once woven, a grid with a percentage of vacuum of 53%, always before assembly. Such a grid is available; for example, at the company Tripette and Renaud, 20 avenue Marcellin Berthelot ZI Val de Seine, 92396 Villeneuve la Garenne, France, under the number 03-280 / 53.

The value of the voltage of the homogeneous distribution grid was measured by means of a pressure test of a semicylindrical end finger with a diameter of 8 mm exerting a deformation centered in the middle of the grid. once assembled, the latter bending at its central point.

Figure 4 shows the corresponding curve establishing the relationship between penetration ^• of the finger expressed by the arrow of the grid in mm for a load applied to the pressure finger, expressed in grams. A load of 500 grams applied to the finger in contact with the homogeneous distribution grid tensioned, 20 mm in diameter, is associated with a displacement of 2 mm of the same grid, with respect to the initial position of single contact of the finger on said grid, for which the load is then zero. These results are perfectly reproducible. If the load is removed, the grid returns to its initial position, characteristic of an elastic behavior, without hysteresis. A this measurement makes it possible to check, in a way, the correct voltage of the homogeneous distribution grid. A minimum voltage can then be specified. This minimum voltage makes it possible, in addition, to ensure that the meshes of said homogeneous distribution grid have the expected opening given the geometry of assembly and the constituent materials of said grid.

The deposit of 20 grams per m ² of a hot-melt powder of 80 to 100 microns in size, of particles, is easily obtained by simple manual vibration of horizontal amplitude of 1 cm and for a regular horizontal translation of 5 cm per second.

The hot-melt powder is a co-polyamide powder, manufactured by the company ATOFINA, 4/8 cours Michelet, 92800 Puteaux, France and sold under the reference Platamid® HX 2544 PA. By variation of the conditions of application, in particular the speed of translation it is possible to modulate the deposit to pass on lower deposits of 15 grams per m ² . Conversely, a reduction of this speed allows easily to increase and drop 35 grams per m ^2.

The reproducibility of the deposit is satisfactory, with the operator's actions effectively controlled. The weight variable deposited is essentially that of the horizontal speed of displacement. The device can cover a band surface of 25 mm to 30 mm for each pass. It is advantageously used to fix a piece of fabric on a set to facilitate then its final assembly by sewing.
