Detailed Description Of The Invention

1. spreader structure

Fig. 1 shows the preferred embodiment of spreader 10 of the present invention.Spreader 10 comprises plane basically material piece 20, and this material piece has the interior zone 23 that first side 21 and second side, 22, the first and second sides define material 20.First side 21 comprises at least one hole 30, and preferably includes a plurality of holes 30 that form transmission district 31.Transmit district 31 and not only comprise hole 30, and comprise the interstitial air space 32 between the adjacent holes 30.Described in detail as follows, think interstitial air space 32 existence and be configured in the distribution performance of spreader 10 and the aspect of performance of the material that is assigned with plays important effect.In the embodiment depicted in fig. 1, spreader 10 also comprises and optional cover 40, and it can be fixed to first side 21 dividually, so as on the hole 30 and around cooperate first surface hermetically and blind hole 30 and stoping distributes or the pollution articles for use prematurely before the use of expection.Lid can cooperate first surface around the periphery in each hole 30 or the periphery in transmission district 31.Optional cover 40 and can comprise having on it and illustrate or the label of other suitable landmarks.

Second side 22 does not preferably have the hole and is preferably plane basically, although it is for some application scenarios, wish to have some surface structures in the zone under transmitting district 31 at least (as the kick of the position consistency of a series of and holder 50), correctly directed to help the user.First surface also preferably includes optional grasping part 24, does not have an edge placement of hole and preferred contiguous spreader on it basically.For some spreader structures, wish to comprise that transmitting second of district away from first transmits the district, it is positioned at the first surface of spreader or any one position on the second surface.

Know as Fig. 2 to illustrate that the interior zone 23 that each hole 30 extends internally and enters material piece 20 from first surface 21 forms corresponding holder 50 to hold a kind of material 60 before use.The suitable substance that uses with spreader of the present invention will be discussed in more detail below.Can in different holes and/or holder, adopt various materials, thereby make them before spreader, keep separating and in use mix.The respective performances of this reaction between the composition and active component before hope prevents to use reduces or is useful especially when consuming.In addition, wish to have the hole/holder of one or more skies, with in the product that distributes, add air and/or play receive holder work in order to remove unnecessary product from target surface.

Fig. 2 also illustrates the geometrical relationship between hole 30, holder 20, interstitial air space 32 and the material piece 20.It can be the periphery that arbitrary shape and big or small hole respectively have the border that is positioned at first surface 21 planes and limiting hole.Comprise in material piece under the situation of network that the average size of mesh opening of boring ratio material is much bigger.Interstitial air space 32 is defined as first surface 21 parts between the adjacent holes periphery.Holder is positioned at the inside in hole and comprises the space of material piece inside.The same with the hole, when forming material piece by network, holder is more much bigger than the average size of mesh opening of material.Holder can have identical or different shape with hole 30 on the direction that is parallel to first surface 21.The gross thickness of material piece is T, and it is defined as and is being substantially perpendicular to the opposite first 21 measured on the direction of first surface and the average distance between the second surface 22.On each surface is under coplanar situation, and thickness T is perpendicular to two surfaces, and under the situation with non-planar shaped surface, the plane on corresponding surface is defined as the mean place by the representative plane of topographical surface.

Different with general porous mass impregnated material, use one or more different holders that the function of batching of better control is provided for spreader of the present invention.No matter be to have in the preferred prestrain configuration of spreader of product when making and sell or spreader is independent of product and makes and by the consumer material is added under the situation on the spreader, the geometry of holder and volume can design according to the needs to termination capacity and transfer rate.

In given spreader, transmit the district and comprise a plurality of holes with different size and/or shape, be regular pattern or irregular pattern, holder needn't be filled to identical level or have identical capacity.The intersection of Kong Zaiyu first surface can have any required cross sectional shape, as avette, oval, hexagon etc., but circular cross sectional shape of the present invention.

The degree of depth that holder 50 extends internally from first surface is t.Therefore, because holder forms in material piece 20 as the space, compare with formation holder in thin embossed material (as polymer film), material is the thicker material on about 0.063-0.250 inch rank at least.Material piece 20 is made first surface 21 and the corresponding to material of irregular target surface form by (conformable) that can fully comply with, and for along with first surface through the application in the dynamic environment of on-plane surface and irregular surface, but material piece preferably elasticity comply with.The material that spreader adopted also can be out of shape in the direction of thickness T, and to the target surface supply and the transmission material 60 that are used to be coated with and distribute.Material piece 20 distortion has by this way reduced the volume of holder 50 in deformed region effectively, thereby material is outwards extruded by hole 30 and contacts with target surface from holder.

Compression in the present invention narration is defined as because of applying external force (or otherwise), and scantling T reduces, and makes first surface and second surface draw closer together and inside dimension between the two becomes littler.This and translation or the rotation and to reduce the distressed structure of other form of effective thickness of material different mutually of the surface of wherein material or structure.This thickness more suitably is to be called " paper thickness (caliper) " rather than " thickness (thickness) ", because " the paper thickness " of this material will be greater than " thickness " of the material of making it in definition.This example of structure is three-dimensional embossed film, and it has a plurality of pit or ribs that form therein.Film has preset thickness at first or takes dimensions, but after the distortion that exceeds material plane, the paper thickness of film is owing to the size of rib or pit increases.This material can stand reducing of size in perpendicular to the plane of material plane, but just carries out by means of the distortion of surface that exceeds the plane or structure or destruction.In structure and material of the present invention, paper thickness is identical size with thickness basically, and this is because near the surface planarity deviation the transmission district is very little.Therefore, owing to the influence lower compression of material self in external force, first surface and second surface do not rotate or twist the geometry of material piece towards moving each other.

Do not wish to be bound by any theory, use the thicker plane basically material that holder forms therein and do not use the thin material that forms non-planar structure, the spreader that makes applied force be sent to target surface more equably and carry out more uniform dispensed materials is provided.This point because for most of situations, wishes that final product distribution do not react the pattern of applied force being to apply under the situation of (for example finger that separates by one or several) particularly importantly more dispersedly when the power that apply.For example,, wish on target surface, to form roughly material coating uniformly if a people grasps the spreader pad as shown in Figure 3, rather than four product traces of corresponding four finger positions.

Another key property of spreader of the present invention is that material slips over target surface and do not roll or become the ability of distortion.This also helps to guarantee uniform species distribution on target surface.Therefore, the selection of suitable spreader material not only will be considered shearing and other characteristic of material, but also will consider the coefficient of friction of material and target surface.

Material piece 20 can be in essence by a homogenous material sheet constitute all-in-one-piece, perhaps can comprise two-layer or multilayer material, in addition, hope forms the hole and the holder of complete penetrable material sheet in layer of material, subsequently another of similar or different compositions is stacked in layer by layer on the second surface of first material piece in case the sealing holder to the inner.

For given product, can optimize the design of spreader and make the possibility of too early distribution minimum and make the expectation of required product transmit maximization.Prevent that the method that required product distributes too early from being the long-pending maximization of reservoir surface that makes product adhesion.Product has the compatibility to the spreader surface usually, and therefore, product has the trend that remains in the holder.Yet the long-pending increase of reservoir surface also can reduce the consumer and finally expect the product volume that transmits.Tendency and the corresponding tendency that transmits product of being expected by the consumer that product is remained in the holder are inversely proportional to, but need not to be linear proportional.Do not wish to be bound by any theory, think that along with the long-pending increase of reservoir surface, then the possibility of disperseing too early reduces, and correspondingly (but needing not to be linearly) reduces the product that expectation transmits pro rata for the holder of the constant volume and the degree of depth.This theory is discussed with reference to aspect ratio (aspect ratio), and aspect ratio is that the ratio by [surface area of holder]/[surface area of the cylindrical stored device of the same volume and the degree of depth] defines and calculates.It is believed that then the possibility of disperseing too early reduces along with aspect ratio increases, and correspondingly (but needing not to be linearly) reduces the product that expectation transmits pro rata.When given product is determined to optimize the spreader design, can use this recently more different in length and breadth design.Adopted above-mentioned optimization method for the embodiment shown in Fig. 6,7 and 8, and found: in the use of described product, the spreader of aspect ratio between about 1 to 5 is proved to be gratifying.

As previously mentioned, material preferably of the present invention not only is compressible on thickness direction, and is adaptable (conformable) on in-plane, so that adapt to the landform on all types of target surface in the use.Equally preferably, suitable material piece also be have elastic, preferably on its compressibility and crooked compliance on.Resilience is consistent with its usual meaning, as defined among Webster ' the sNinth New Collegiate Dictionary, is " deformable body is returned to the ability of its size and dimension after the distortion that is caused by compression stress particularly ".The resilience of material makes it attempt to be returned to that it is not out of shape, preferred planar shaped state and initial thickness basically after compression stress or bending force remove, thus make its can be consistent with all types of target surface and maintenance be used for dispensable materials suitably with contacting of target surface.

Preferred material property and preferred material of the present invention (Volara 2EO 1/8 " the crosslinked foam of polymers of PE/EVA polyethylene/vinyl vinyl acetate co-polymer (12%VA) pore; Can be from Voltek; 100Shepard Street; Lawrence, MA01843 buys) performance shown in the following table: performance Volara2EO 1/8 " preferable range test method thickness (inch) 0.125 0.063-0.250 ASMD-3575 density (pound/cubic feet) 2 nominal 2-6 ASMD-3575 tensile stress psi (MD), 55 minimum 40-200 ASMD-3575 elongation at break % (MD), 140 minimum 100-350 ASMD-3575 resistance to tearing pounds/inch (MD) 7 minimum 4.5-30 ASMD-3575 compression stress psi@25% deflection 2.5 minimum 1.5-15 ASMD-3575@50% deflection 9 minimum 4-25 ASMD-3575 compressions (%) 30 maximum 0-50 ASMD-3575

Although Volara 2EO is preferred, can use other Volara level and other foamed material (as open celled foam, non-crosslinked foam, have the foam of various size of mesh opening), other resin, 100% polyethylene, polystyrene, polypropylene, rubber, urethanes, other ethylene copolymer, propylene copolymer and other have the synthetic material of analog material performance.Notice that use for some, harder or softer material is preferred.

In the embodiment shown in Fig. 1 and 2, holder has the sidewall of the first surface of the material piece of being substantially perpendicular to.Yet, to be sent to the formula for a product of the material of target surface for some, be desirable to provide the angle of holder sidewall wherein and be not 90 ° holder and hole geometry, for example funnel shaped hole/holder geometry that tapering is arranged, wherein along with the increase of the inside distance of distance first surface, holder narrows down; Or " incision " hole geometry, wherein along with the increase of the inside distance of distance first surface, holder broadens.According to the manufacture method of selecting and the material that is adopted and the character of material piece, holder can be formed with general plane shape bottom (away from the hole and be positioned at the part of material piece inside), or fillet can be cut in the bottom of holder.

In addition, preferably when material piece comprises porous material, holder comprises that some prevent that material from moving to the appropriate device in the matrix of material piece.The method for optimizing that prevents this migration is the foamed material that adopts closed pore.It maybe can be that some other gives reservoir wall impermeable device that yet this device also comprises impervious coating, as hot melt porous materials film in the process of hole and holder formation with formation " epidermis " (skin).Second side 21 that layer in addition or polymer coating (as PET, nylon etc.) can be used in reservoir wall, spreader or other are wished on the zone of restrictive substance penetrable material.Can adjust the concrete combination that any such processing or method adapt to material and spreader material.Use for some, the inner surface of also wishing holder and hole has topographical surface to a certain degree, to help fixedly material.Wish to have some such as projection, boss, internal structure such as ring helps keep material on every side.Can adopt various holder configurations, and the global shape of the shape of limiting holes or spreader not, can adjust these configurations as required and be convenient to keeping and/or distributing of material.

Fig. 3 shows the schematic diagram of spreader 10 of the present invention, and this spreader is used for applying material to target surface.As shown in Figure 3, spreader 10 is grasped by user's hand 80, normally presses the spreader between thumb and the palm, near the second surface 22 the finger contact hole 30, and thumb contact grasping part 24.The user contacts the transmission district of spreader 10 with target surface 90 subsequently, target surface can have any topographical surface and can be the plane or nonplanar, the user is applied to the power that has normal force vector component F on the F direction at least, and this direction is approximately perpendicular to target surface 90.Apply the tangential force or the force vector component (preferably applying simultaneously) that act on the direction D with normal force F, roughly the coating of uniform material 60 is applied on the target surface with mobile spreader on target face 90, preferably the zone that is consistent with transmission district 31 and travel distance basically.Normal force and tangential force merge and limit planar shaped with first surface into about the 0 total force vector to about 90 ° of angles.This mode that applies is distributed material during the distribution of this method, rather than extrudes after distribution usually or distribute material.

Dynamically applying in the process as shown in Figure 3, to apply situation different with " static state " that do not have the relative translation campaign, it is believed that the relation between the gap is a factor of wanting emphasis to consider when design is applicable to the spreader geometry of concrete material between hole (adopting a plurality of holes) and hole.Each hole have by the part of material piece first surface around periphery.Because material piece (its first surface at least) is general plane shape preferably, thus each hole by around the general plane shape rings of material on contact target surface, hole around, rings of material provides " being rubbed into " (" rub-in ") surperficial with dispensable materials on target surface.Be flowable or when using, become to flow the time that at material this rings of material forms washer-shaped surface, help by advancing product outwards to flow and dividing lively stock equably from the hole.Alternatively be, if necessary, can be applied between the hole with a certain amount of superficial makings (as microtexture) and/or the hole near the part of first surface on, to help distribution function and/or to help to be coated with the aesthetics of function at aspects such as dermal sensations.

Spreader of the present invention shown in Fig. 1-3 has corresponding a plurality of holes and a plurality of holder, and preferably the ratio of hole and holder is 1: 1.Yet the combination of other hole and holder also is fine, such as a plurality of holders being provided for each hole or being supplied to a plurality of holes by single holder.Figure 4 and 5 show a kind of alternative embodiment.The spreader 110 of Figure 4 and 5 has the material piece 120 of the material piece 20 that is similar to Fig. 1-3, but different with spreader 10 is, spreader 110 has from first surface 121 and begins to extend internally inside 123 by material piece until a plurality of holes 130 of second side 122, thereby the path that is not stopped fully that runs through material piece 120 is provided.In this embodiment, the thickness T of material piece equals apart from t (for clarity sake omitting).Hole 130 forms to transmit distinguishes 131, and transmit the district and separated by interstitial air space 132, and preferred but optional by removable lid 140 coverings, explanation or other suitable mark are arranged on the lid 140.Spreader 110 also comprises backing sheet 170, the backing sheet combines with material piece 120 on periphery by heat seal 125 or other suitable Sealing Technology, backing sheet 170 is with sealing 125, material piece 120 and cover 140 and form at least one, and is preferably only holder 150 that holds product 160 therein.

Another kind of distortion be included in to similar embodiment shown in Figure 1 in only use a bigger holder, but comprise a plurality of " islands " of giving prominence to from the bottom surface of holder, be rubbed into the surface so that the surface contact that is similar to the interstitial air space network that forms between a plurality of dispersion hole shown in Figure 1 to be provided.

The hole of spreader of the present invention can be by sealing with using the lid/label diverse ways as lid 40/140 before use.For example, spreader can be with face-to-face or back-to-backly concern sealing-in or be adhered on another, makes the hole of a next spreader of surface sealing of a spreader.Other possible orientation comprises that transmitting the district does not line up but cover face-to-face orientation on the other parts of first surface, in the face of carrying on the back orientation etc., paired this material can be encapsulated in the barrier film (sheet metal, the polymer of plating etc.) to form packing easily.

Spreader of the present invention comprises the transmission system of the packing with shearing force connecting gear.Other example of this transmission system is known in the art, and generally includes and have subsidiary shearing force connecting gear packing or container of (as the cap of perforation or the surface of perforation).The shearing force connecting gear makes the material of transmission be subjected to shearing force, offsets material and builds up and/or keep the trend of bigger or thicker deposition and spread apart on target surface.When rheological characteristic and other products characteristic change under the shearing force influence (becoming easier as material under shearing flows), shearing force to apply with combining of material transport process be particular importance.To the rheological properties of material be made further discussion below.

An embodiment of the antiperspirant composition that the application describes is the anti-sweat cream that selected rheological profile figure is arranged.Rheological profile figure is defined as in this application for antiperspirant cream composition, the δ stress (dynes per centimeter of selected product ²) and static yield stress (dynes per centimeter ²) value combination.The assay method of two key propertys of this of rheological profile figure will be discussed in more detail below.Unless otherwise indicated, the mensuration of rheology method is to carry out under 27 ℃, the condition of 15% relative humidity.1. assay method: δ stress and static yield stress

In order to measure the δ stress and the static yield stress of antiperspirant cream composition, with rheology dynamic stress flow graph (available from Rheometrics Inc., Piscatawany, New Jersey, U.S.A) analyzing said composition also uses Rhios software 4.2.2 (also available from Rheometrics Inc., Piscatawany, New Jersey U.S.A) carries out Collection and analysis to data.The structure of flow graph is the parallel discs pattern with the taking over a business an of 25mm (available from RheometricsInc., Piscatawany, New Jersey, U.S.A, part number is LS-PELT-IP25).Temperature control is set to 37 ℃.Default test model with " Stress Sweep:steady sweep " is analyzed anti-sweat cream.The primary stress of flow graph setting is 1.0 dynes per centimeter ², final stress is 63930 dynes per centimeter ², stress increment is 100 dynes per centimeter ², the maximum time of each data point was 5 seconds.

The used term " static yield stress " of the application refers to the analytical method of describing according to the application and must be applied on the antiperspirant cream composition so that the minimum stress (dynes per centimeter of taking over a business to move about 4.2 microradians of rheology dynamic stress flow graph ²) amount.In other words, static yield stress is illustrated in the point that flow graph in the stress scans analysis of product can be measured product viscosity at first.

The used term " δ stress " of the application is that the dynamic yield stress by composition deducts static yield stress and definite.Dynamic yield stress is to measure viscosity to begin the point of decline fast.This can be 100 dynes per centimeter by the increment between stress value ²In time, found last stress value and measures at an easy rate.In other words, the δ stress of composition is represented to be applied to makes composition liquefy substantially on the composition, exceed the stress increment of the static yield stress of composition.

Be packaged in mensuration its rheologic behavio(u)r in back in the spreader of the present invention at antiperspirant cream composition.From spreader, shift out a part of composition carefully and make product be subjected to minimum shearing force, particularly can not make it to curl or be reassembled into the shape of this part when being different from it and from composition, shifting out.Carefully this part is lain on the chassis of flow graph, in put procedure, make the shearing force minimum that is applied on this part.The area of this part of placing is equally big to guarantee that two dishes have correct contacting in process of the test with the area of taking over a business at least.Make then towards the chassis to descend, place about 2mm place, top, chassis, so its anomaly is placed on the about 1mm of product section on the chassis.Speed with minimum further descends towards the chassis, places about 1.000 (± 0.002) mm place, chassis top, this moment product is placed on the chassis gently and take over a business between also contact with the two.Lightly the dish of two parallel placements outside and excessive product are on every side scraped off with scraper, carefully make the product that places between two dishes be subjected to minimum or be not subjected to shearing force from scraper.Use liquid-carrier to make the solvent neonychium on the flow graph saturated corresponding to the test products type.The solvent neonychium is dropped on two parallel discs to prevent to place in the analytic process solvent loss of the test products between two dishes.Can carry out rheology analysis and measure dynamic stress, static yield stress and δ stress this moment.

According to said method outturn sample is carried out rheology test and assessment.Stress (the dynes per centimeter that the data that above-mentioned analysis is obtained apply with respect to linearity as the logarithm of viscosity (handkerchief second) ²) mapping.Instrument measuring is exactly static yield stress (that is: instrument shows the minimum stress of non-zero viscosity) to the initial point of viscosity.Dynamic yield stress is that the viscosity of measuring begins the point of decline fast.This can be 100 dynes per centimeter by the increment between stress value ²In time, found last stress value and measures at an easy rate.Deduct static yield stress with dynamic yield stress then and determine δ stress.

The static yield stress value of antiperspirant cream composition is about 4000 dynes per centimeter at least ², more preferably be about 8000 dynes per centimeter at least ², even more preferably be about 40000 dynes per centimeter at least ²The maximum static yield stress value of said composition is preferably less than about 120000 dynes per centimeter ², be more preferably less than about 63000 dynes per centimeter ²

The δ stress value of antiperspirant cream composition is about 300 dynes per centimeter ²To about 8000 dynes per centimeter ², preferably about 1000 dynes per centimeter ²To about 6000 dynes per centimeter ², be more preferably about 1000 dynes per centimeter ²To about 5000 dynes per centimeter ²δ stress can cause in the shearing force transport process solvent dehydration to shrink less than minimum of a value, but can cause product to distribute inequality on skin greater than above-mentioned maximum when this value, reduces its distributivity at the crinosity position of skin particularly on skin.Therefore, the described δ stress value of the application can produce minimum or do not have solvent dehydration to shrink and can be on skin uniform spreading, particularly pass the crinosity position of skin or smooth paste product that can fine distribution thereon.

Other material

Though above-mentioned discussion concentrates on and proves and can be fit on predetermined substance such as antiperspirant composition that spreader of the present invention uses, but should be understood that: principle of the present invention can think can be used in other spreader/material in conjunction with last, spreader wherein is designed to adapt to the characteristic of material and the character of applied environment.For example, it is believed that other composition such as sun-screening agent, the cooking product such as fat, oily and cooked, wax such as footwear buffing compound (shoe polishes) etc., and other material can be fit to use with spreader of the present invention.

According to the present invention and the material that is used in combination of deformable material have the certain physical performance and enable to distribute and be applied on the target surface from the shielded position of three-dimensional structure.Being distributed in like this can be part in nature, or substantially completely or all completely.

In order to promote such distribution, think that important Substance Properties comprises that material is with the relative compatibility of target surface and material and deformable material and by the apparent viscosity or the flowability of three-dimensional structure activation back material.Think that now material preferably should be greater than the degree of adhesion of itself and deformable material and/or greater than the degree of adhesion of itself and the other parts of material own with the degree of adhesion of target surface.In other words, the compatibility of material and target surface is greater than its compatibility with and/or deformable material sheet own.

Material itself can have viscosity and flowability that it can be discharged from its position of being protected in the material piece or need improve viscosity discharging and disperse.The improvement of viscosity can be by selecting and can obtaining in response to the material that selected active mode changes viscosity.For example, for mechanical activation such as extruding force, may need and preferably use to be referred to as " shear thinning " (pseudoplastic behavior) material usually.This examples of substances comprises polymer solution, the wood stain of many gels and pastel such as dentrifice and body cream, coating, gelling etc.Other material only reach or greater than a certain threshold value shearing force (yield stress) after could be as the shear thinning material.Such material is referred to as the Bingharn plastic material usually, and a general example with material of this performance is a kind of condiment that is known as catsup.

Think that but the bonding of ectocrine confrontation target surface or some factors of affine performance comprise: static or electric charge; Utilize the chemical bond of hydrogen bond, covalent bond, ionic bond, part ion key (part two polar attractions), Van der Waals force, penetration etc.; Capillary pressure (suction); Absorption; Absorb; Vacuum/suction etc.Other important factor comprises the wetability of material on target surface, and this reflects with the contact angle of material on target surface.

In order to promote distribution or the dispersion of material on target surface, particularly be retained in the trend on the fixed position on the deformable material in order to offset material with the given location method of salary distribution, the present invention preferably uses and can adjust so that the material of wetability to be arranged on target surface.Other help material the factor of disperseing on the target surface or distribute comprise use have the material of shear thinning performance and remove from target surface after activation but with deformable material before the mechanical distribution effect that produced of user's the side direction mechanical movement of composite material sheet.Such side direction mechanical movement also can produce with the additional interaction of material such as shear thinning material and can produce extra benefit as bubbling, produce foam, shampooing/rubbing action etc.

When part deposition or the material that disperses were coated onto the target surface that did not have deposited material originally subsequently and partly go up, successful dispersion had just taken place.When material piece was removed from target surface, at least some materials remained fixed on the target surface, preferably in basic mode uniformly.

As mentioned above, can select many different materials to be used for principle of the present invention.In order to reach illustrative purposes, representational material comprises cleaning agent such as soap and washing agent, emollient such as washing lotion, and medicament such as ointment, anti-inflammatory ointment etc., vigorous and graceful care product comprises anti-perspirant, deodorant, cosmetics, spices etc.Other multiple use of this class material piece comprises the spreader that following products is used, described product comprises: automatically and product such as lubricant, colouring agent, protective agent such as oil and the wax of family expenses, binding agent, anticorrisive agent etc., and purposes in the field of food such as flavouring (wasabi, catsup etc.).

Also can use multiple material, these materials not only can not contact easily but also originally be to isolate (on same of material piece, or on the relative face) each other, and they mix mutually in activation or distribution subsequently and/or dispersion process.Such design for can advantageously interact (as: being divided into diffusing epoxies, catalytic reaction etc.) with each other and/or and target surface between provide the material of additional function particularly useful.Also wishing provides dispensed materials progressive or order by the geometry of adjustment spreader or the performance of material, so just can be in the initial back passing by the time of smearing, the progressive distribution that increase pressure etc. adds.3. preparation method

The mode of the material of available any geometry that is applicable to expection and expection and related material is produced spreader of the present invention.For example, for the preferred top hinged foamed material of the present invention, the structure of Fig. 1 can be made like this: form the required degree of depth with the hot padding method with a heated mold and form many holes and holder, then material is injected holder or material is full of spreader and scrapes off unnecessary material.Transmitting in the district labelled or strip of paper used for sealing and fixing then by heating or with mull technique.Then spreader is die-cut into final shape, die-cut step also can be finished when forming holder or other any suitable design procedure.For such process, it is flowable material to be become by heating or other method if desired.

In the embodiment that single holder is arranged as shown in Figure 4, can prepare coating surface similarly, available heating or other method make the combination of backing sheet periphery, and material can be from single raw material source or can be injected holder from a plurality of raw material source if desired.

Though have illustrated and described the specific embodiment of the present invention, it is conspicuous carrying out many changes and improvements under condit without departing from the spirit and scope of the present invention to those skilled in the art.All these improvement all should cover in the scope of appending claims the present invention for required protection.
