Description

Handheld manual is distributed agate fat container and material therefor thereof

Technical field

The present invention relates to a kind of handheld manual and distribute agate fat container and a kind of method of distributing agate fat, particularly its material therefor.

Background technology

Agate fat is a kind of material that is used to build with Repairing ﹠ Maintenance, particularly can use it in auto trade and fill up depression and scratch etc.

Agate fat is a kind of soft putty-like material, has very heavy body and stickness.Recording its rate of shear (rotating speed) with the Haake fluid meter is 7.22 seconds ^-1, general, its viscosity number is the 3500-1500 pool under 10 ℃, its viscosity number is the 1500-650 pool under 30 ℃.Usually, agate fat is distributed on the flat surface, here with scraper it is mixed with the hardener that quite lacks predetermined ratio, to start a kind of chemical reaction, this reaction makes compound in predetermined firm time internal fixation or sclerosis.

Loose compound should be easy to launch, so that for example be coated on the automobile, but in case after being used for repairing, has only used automatic homogenizing compound in homogenizing automatically in using, and is just no longer mobile.The compound of this curing should form a kind of hard and smooth finished product.To conscientiously select firm time, so as the work-hours of useful length and do not wish to average out between the long firm time.In order to reach above-mentioned standard, when selecting the chemical constitution of agate fat, need rich experience and especially conscientiously.Because agate fat has very high viscosity usually and produces strong chemical gas by the solvent that is wherein adopted.For above-mentioned reasons, the storage of agate fat and distribution not a duck soup, especially owing to contain styrene in this agate fat, its packing is very difficult.

Traditionally, use for commerce, agate fat is stored in the dispense container that comprises metal tube, fills from Guan Yiduan, and the distributing nozzle of a convergence is arranged at the other end.Make an end cap force to slip in this pipe with an isolated plant or rifle then, so that agate fat can be extruded from distributing nozzle.Adopt similarly device distributes hardener from a tubule.

Usually, for the less non-commercial use of agate fat consumption, do not use metal tube, because the cost of relative agate fat itself, the cost of metal tube is too high.Should be pointed out that this cost partly comes from the cost of metal tube itself, part comes from fills relevant with transportation with the storage of the blank pipe before cost of agate fat.Therefore, as the substitute of metal tube, adopt little tubular to listen (tin can) with lever cover.By knife being inserted the distribution of carrying out agate fat in the agate fat, and it is being taken out the back with mixing from the hardener in the pipe.Yet this is really not satisfactory, because the agate fat that is contained in listening is done easily, the user can contact chemical gas more, and the situation that extender paste pollutes also can take place.In addition, when filling tin can, agate fat may absorb air, produces bubble in final compound, and this impairs the bright and clean of curing mixture, and tin can and filling cost thereof are also quite high.And, also can be subjected to the pollution of the dust etc. of operation field.

The size of above-mentioned tubular tin can is also bigger, also is to be used for commercial object.The metal tin can of above-mentioned sheet tin type is used always, because it can seal by solvent, the particularly gas that styrene produced in the agate fat.This tin can still is a kind of container that keeps its integraty, and in other words, long-time placement can not leaked, and can not break if fall once in a while on the ground in busy workshop yet.The difficulty of the agate fat that spills in view of the harmful character and the cleaning of its strong chemical gas, above-mentioned back becomes a kind of significant consideration on the one hand.And therefore the inside face that the cmpd in the agate fat can this tin can of very fast corrosion, can stipulate quite long guaranteeing the quality storage period.

Someone proposes to use the container that is made of plastics.The container that use is made of plastics can more effectively reduce agate fat is delivered to cost required in end user's hand.In addition, the cost of this container itself also is significantly less than the cost of metal tin can, and the production of this container, transportation and filling cost also significantly are lower than existing container.

US-A-4 795 062 has disclosed a kind of big bag-like container, and it is roughly square material piece and is formed by two-layer, is welded together around it, forms the seam edge of four linearities.Then a spray nozzle device is bonded on one of them sheet material, and with this sheet surface valve nozzles device, up to use.This container is simpler than above-mentioned metal tube, and but, this container is difficult to open.In addition, in use this nozzle may become very dirty, because the viscosity of agate fat and stickness are very high, and nozzle also can come off from described sheet surface sometimes.Moreover, owing to must use the particular allocation device, must buy distribution device in order to use this container.This makes this container not be suitable for non-commercial purpose especially.

Also there is other problem in the agate fat container that plastics are made.Particularly, found that selected plastics can not provide the shielding of appropriateness, to limit the severe corrosive chemical gas of agate fat suitably.Find that also the seam that formed by plastics can not the pre-anti-leak of appropriateness, and weaken as time passes, thereby increase the weight of this problem.In addition, if this container that is made of plastics falls on the ground, catastrophic damage can take place in its seam.As time passes, the danger that this problem occurs increased, thereby is difficult to stipulate a sufficiently long storage period, as 2 years.Have found that back one problem may come from plastics by solvent for use dissolving in the agate fat, cause the pollution of agate fat, softening container is out of shape to produce, and weaken its seam and wooden partition; Also may come from the sclerosis that described solvent has caused container seam and wooden partition, make this container occur leaking and fragility.At last, the use of plastics makes people to pack with the transparent material that can see agate fat.But, have found that plastics can feculence.

Embodiment

Referring to Fig. 1 and 2, it is to be made by two transparent plastics that a kind of handheld manual is distributed agate fat container 1, and seam around it 7 is welded together it.This container is made with a distribution openings limit 4 and a filled end 3, and the two is parallel to each other.This container is roughly microscler, and it extends to its maximum width at of being indicated by numbering 6 from distribution openings, assembles to filled end then.The widest part 6 is positioned to count from distribution openings limit 4 along 2/5 ' S of elongated shaft linear distance with from filled end 3 counts about 3/5 ' S along the elongated shaft linear distance.

Like this, formed roughly as numbering two trapezoidal portions shown in 11 and 12 difference.Near the volume of the part 11 on distribution openings limit less than volume near the part 12 of filled end.

As shown in the figure, seam 7 forms leg-of-mutton fin 2 extending laterally near place, distribution openings limit.Each fin 2 is provided with 3 breach 5.To understand the purposes of these breach by following explanation.

Described container is made like this: two plastics are cut into the shape that needs, and the seam along all limits except that filled end 3 is welded together it then.In this container, fill agate fat then, seal filled end again, form a kind of leak free container.Be understandable that, can local make unfilled container, and be transported to another place and fill at one.

In order to use the container of this embodiment, cut seam 7 along distribution openings limit 3, to expose agate fat.Can form the outlet of a preset width like this.3 set breach 5 are the outlets that are used to indicate different in width, and then realize the control to agate fat dispensing rate.Fin 2 also forms a rigid element at place, distribution openings limit, thereby has improved the stability of this outlet.

In order to distribute agate fat, described container is held in the hand, make its widest part 6 fall into palm.Then volume 12 places are exerted pressure, to extrude agate fat.Because the shape of this container, this outlet are convenient to operation, thereby can carry out distribution clean, easy and cleaning.In addition, need not special-purpose distribution device or special-purpose cutter.And the weight of volume 12 is greater than the weight of volume 11, so the weight of filling containers is positioned at more near the health place on the whole, thereby improved the control to the outlet at 4 places, distribution openings limit.

In this case,, the length of this container is made 260mm for common hand length, but can be between 200-300mm.

In this case,, the widest part 6 of this container is made 140mm for common palm span, but can be between 100-200mm.

The width of filled end 3 is 30mm, and the common width of distribution openings and fin 2 is 60mm.

The handheld manual of second kind of embodiment of the present invention is distributed agate fat container as shown in Figure 3.Container 31 preferably is made up of plastic sheet, is preferably transparent or semitransparent.This container be made for two trapezoidal, one of them is bigger, two trapezoidal is bonded together along its long base, forms one between the filled end 33 of this container and the intermediate point 36 between the distribution openings 34.Therefore, along the width of the intermediate point 36 of this container axial length greater than filled end 33 and exit end 34.This intermediate point 36 is positioned at from exit end 34 to be counted 2/5 ' S of its axial length and counts 3/5 ' S of its axial length from filled end 33.The narrowest place by this shape forms exit end 34.

Forming bigger trapezoidal apparent surface is sealed along side face seam 37 and 37A.Forming less trapezoidal apparent surface is sealed along side face seam 38 and 38A.

After the filling, be sealed along the two opposite surfaces of filled end seam 39 with filled end.Be sealed along the two opposite surfaces of end joint 40 exit end 34.Be provided with a spray nozzle device 41 at exit end, this nozzle forms the shape that is roughly T shape by bottom 42 and upstanding portion 43.The bottom 42 of device 41 is sealed in 40 li of end joints.Be provided with a central outlets passage 46 on base 42, this passage extends to discharge nozzle 44 along upstanding portion 43 axis by this part from container 31 inside.On upstanding portion 43 outside faces, be useful on to admit and cover 45 screw thread.Can on lid 45, connect a securing device or clamping band, with fixing on the throne lid 45.The outside face of base 42 comprises the band that is used to help adhesive joints 40.Described bottom is positioned at along the middle part of seam 40, but only extends along the part seam.

Adopt described second kind of embodiment, have all discharging advantages of first kind of embodiment, but different be that this container is by a lid sealing.Therefore, second kind of embodiment is applicable to the sticking inadequately fluent material that is not enough to rest in the container, but the tendency of outflow is arranged, but use spray nozzle device can easily seal this container, make it still can be used for more tacky agate fat, but need wideer outlet nozzle and exit passageway in this case.By adopting spray nozzle device 41, can seal this container, rather than inherent viscosity of institute's package material remains on material wherein in the dependence container.

The production of container of the present invention is simple, inexpensive, therefore, can produce the container more more convenient than existing agate fat container, that cost is lower.The shape of this container helps it is held in the hand cosily manually controls the wherein distribution of agate fat.Along with extruding of agate fat, its center of gravity still remains on the wideest part place of container, then still keep this container to be arranged in palm, thus can during distribution continue it is operated easily.The shape of this container makes can be added in bigger trapezoidal portions equably with pressure, and this part is molded as the shape of hand-held container.The light pressure that applies herein can be extruded agate fat.

And because this container is complete leak free, agate fat wherein can keep relatively not having air, so the final hardening product after coating can have good degree of finish.In addition, because the shape of container can control it better,, avoid the formation of bubble thus when agate fat is extruded with smoothly, extrude equably with agate fat.Can be reduced in the possibility that occurs pin hole in the product of final sclerosis like this.Therefore, the degree of finish that can be improved.In addition, by the instrument of simple change production container, can obtain container remarkable alerting ability dimensionally.Particularly, this container can be made the suitable dimension that can hold for the accurate amount of the required agate of one-shot usage fat.In this case, this container is promptly discardable after using once, to avoid owing to the waste of longer-term storage material.

And, although transparent thermoplastic sheets is illustrated, also can use the sheet material of other form.Should be pointed out that and to use material transparent, because adopt transparent material that agate fat is degraded because being subjected to ultraviolet irradiation.In addition, described sheet material can be individual layer, bilayer or trilaminate material.Should be appreciated that and remove fin 2 and mandatory sign 5 resembling in Fig. 3.

In another aspect of this invention, container shown in the accompanying drawing also can be made by the laminated plastics sheet material.This stratiform sheet material has a selected layer that is used to intercept the chemical constitution of agate fat, it can with the bonding or sealing of another such layer, also have an outer cover, this outer cover provides the structural strength of container separately or with the layer of mentioning the described first time.

In one embodiment, layered sheet material is a kind of flexible sheet material, and it has been made into a polyethylene inner layer, an outer layer of polyethene and has had an ethylene-vinyl alcohol copolymer interlayer to be clipped between the two.More than 3 layers all make sheet.

The sheet material of one volume, 3 layer materials is being folded by machine so that its internal layer is relative.This machine is cut into all shapes as shown in Figure 1 with sheet material, heats around seam 7 then.In this case, heat makes polyethylene inner layer be bonded together, and constitutes an agate fat container by it with the broken line along distribution openings limit 4.Fill by 3 pairs of these containers of filled end then, along its edge heating,, thereby seal this container again so that polyethylene inner layer is bonded together along this edge.This machine is well known in the art, because of rather than component part of the present invention.Should be appreciated that and to adopt microwave or alternate manner to realize described sealing/bonding.

Selecting polyethylene is because it can not dissolved as styrene by the solvent in the agate fat as internal layer.Therefore, this layer can not soften or harden.In fact, this solvent is also more stable relatively for polypropylene, therefore, can not cause the chemical reaction of chemical damage with the generation of agate fat.And, can carry out good sealing and bonding between polyethylene and the polyethylene, form leak-tight seal seam 7 thus.But, polyethylene can be by solvent and the gas permeation in the agate fat, therefore, and can not be used as container itself.After through a large amount of tests, ethylene-vinyl alcohol copolymer as interlayer, can be intercepted chemical gas in the agate fat because found it, guaranteeing sealing to this container, and not can with this generation of gas reaction.Selecting polyethylene to make skin is because it has fabulous structural strength, so can guarantee the integraty of container.And, can feculence through polyethylene after the long-term use or ethylene-vinyl alcohol copolymer, therefore can prolong its storage period, and the buyer that the container of agate fat is housed can see product wherein and whether rottenly check.But, should be pointed out that the existing opaque material of preferred use, go bad because of ultraviolet irradiation to prevent agate fat.

Have found that, when above-mentioned elastic sheet material is used to make container shown in Figure 3, in spray nozzle device 41, the heat seal problem can occur.The appearance of this problem is because a large amount of heat of bonding needs between formation spray nozzle device and the internal layer.As a result, can damage skin, make near the position reduction of this device, if this container falls can make on the ground it to break.Therefore, preferably use heat proof material as skin in this occasion.Have found that the nylon skin is suitable especially, can solve above-mentioned reduction problem.

In another kind of embodiment, layered sheet material is harder sheet material, and it has been made into a polypropylene internal layer, an outer layer of polypropylene and has had an ethylene-vinyl alcohol copolymer to be clipped between the two.More than three layers be made into sheet material.

The sheet forming that with the accurate vacuum forming machine of a station symbol with thickness is 850 μ m is in a mould, and shape is made a container with the end that is substantially rectangle, and it has upright wall, forms the upper opening that is roughly rectangle, to make tubbiness.The top edge of this wall has a lip limit of extending along its upper opening on every side.Fill this container with agate fat then, and will or be combined in a similar manner on the described lip limit with the lid heat bonding made from described wall same material.Then, when openable container, this lid is torn.An interchangeable lid that material is identical also can be set.

Found that this container can stop the solvent in the agate fat to leak by its bottom, wall or lid.In addition, have found that the effect that its bottom and wall can overcome because of solvent in the agate fat takes place recessed or crooked.And behind contact bottom and wall, agate fat is still unaffected basically.Therefore, can realize the storage period that agate fat is long generally.In addition, this material has bigger structural strength, and as time passes, this intensity remarkable change can not take place, even fall on the ground, the integraty of this container can not break impaired yet, and the shape of long-term use container can be out of shape yet.

The shape that is appreciated that described container is essentially tubbiness, but also can select other wide-mouth shape for use.The application of vacuum forming is favourable, because it is a kind of quick production technology, and can produce different shape.

Find that in experiment with the container that above-mentioned plastics are made, use still can keep its integraty later in several years (to reduce check by weight) with regard to agate fat leaks, and kept good surface appearance.

Although be appreciated that polyethylene inner layer is illustrated, this one deck can save.Can be although illustrated with polyethylene as internal layer and skin, this internal layer and/or skin also can be polypropylene.

Should be appreciated that of the present invention a kind of application form that described embodiment just provides for explanation.In fact, the present invention can have multiple multi-form, and to those skilled in the art, its embodiment is conspicuous.
