When core is covered by two polymer sheets, the bottom surface of bottom sheet covering core, extension (if present) with And at least a portion of the thickness of the width of core, and at least the one of the thickness of the top surface of top-sheet covering core and width Part, is forming the small overlapping of the first sheet material and the second sheet material, if desired around width.First sheet material and the second sheet material Overlapping at least a portion (for example, at least a portion close to the lap of the edge of one or more sheet material) can be by Seal feature is strongly sealed together, for example, by using band, sealant (sealing solvent), sealingization Compound or machinery and/or heat seal, and such as ultrasonic sealing device can be included.Band, sealing fluid, sealed compound Or machinery and/or heat seal, and such as ultrasonic sealing device can be included and be used to assist the overlapping of the first and second sheet materials Partial edge seal, can also assist in and seal the remainder of the first and second sheet materials to core and assist first and the The remainder of two sheet materials seals against each other.

The edge of sheet material or film can be the outer rim of sheet material or film, or the edge of the folding when some flangings occur.

In general, polymer core can be steeped by such as polystyrene foam, polyurethane foam, vinyl foam, acrylic acid The foamed material of foam or phenol foam is made.Foam of polymers usually can be closed-cell foam (closed cell foam). The closed-cell foam can also provide certain surface roughness, thus contribute to its be adhered to feature and/or polymer film or Sheet material.The density of foam can change, and the bearing capacity of bearing structure is usually not significantly affected.But, it is generally accepted that The density of increase polymer core (or foam) can influence the intensity of the bearing structure obtained, i.e. the density of core is got over Height, the intensity of bearing structure are higher.Therefore, using the foam of higher density, the polymer core of relatively small thickness can be obtained, So as to cause, in the case where having substantially no effect on the bearing capacity of bearing structure of acquisition, to make the thickness of width segments smaller.Hold Load structure, which can include, can not also include extension.In some cases, the shorter bearing structure of shape is advantageously possible for transporting It is defeated be also limited except the weight external space cargo when, be so favourable.

Using the low-density core of the individual features coordinated with impression and together, can also realize with improving load-carrying properties Relatively small thickness or compared with little profile bearing structure.The bearing structure, which can include, can not also include extension.Cause This, this feature can improve the performance compared with low-density core, without using higher density to the shorter bearing structure of shape Core.

Polymer sheet or film can be made of any filmogen that can assign core material intensity, core material for example, Including but not limited to high impact polystyrene；For example, polypropylene, low density polyethylene (LDPE), high density polyethylene (HDPE), polyethylene and poly- The polyolefin of butylene etc；Makrolon；Acrylonitrile-butadiene-styrene (ABS)；Polyacrylonitrile；Polyphenylene oxide；There is high-impact polyphenyl The polyphenylene oxide alloy of ethene (HIPS)；The polyester of such as PET (polyethylene terephthalate), APET and PETG etc；It is unleaded Polyvinyl chloride；Copolyester/makrolon；Or the copolymer of any of above polymer；Or composite HIPS structure.

In general, cover layer or sheet material can not have an impact the gross thickness of bearing structure.However, polymer film or The intensity of person's sheet material is higher, then cover sheets or film can be thinner, and without sacrificing the overall strength of bearing structure.This feature It can be made of polymers mentioned above, as described above.For by either sheet material is essentially identical or similar poly- with cover layer Feature made of compound, from using different polymer phase ratios, adhesion or bonding between feature and cover layer can be more preferable, Regardless of whether this feature is applied before or after using polymer sheet or film cover aggregation thing core.

In general, the edge of bearing structure may include the polymer core by polymer sheet or film covering, as described above. In some embodiments, supplementary features can intermittently or consecutively appear in some perimeters.This feature can usually change The intensity at kind or increase bearing structure edge, so that during use or the abrasion during reusing or destroy minimizes.

In general, feature can include extention, to improve this intensity and can increase the weight of bearing structure sometimes Amount.For example, this feature may include edge protector, as described below.Edge protector can reside in core or polymer sheet On.When being present on core, either film can be combined or bonded with or without edge protector polymer sheet.If side Edge watch box is not combined or bonded with one or more polymer sheet, then the outer rim of sheet material can be glued by seal feature Close edge protector.If edge protector is combined or bonded with one or more polymer sheet, the outer rim of the sheet material Edge protector can also be adhered to by seal feature.

In these embodiments, bearing structure can be strengthened with some edge protectors.When the cargo being loaded in structure Article compacting is kept by cargo, such as helps to fix with bandage, tie-down (tiedowns), cable, rope and/or other articles During cargo, particularly in transport, it may be necessary to which edge protector, minimum is reduced to by movement.In use, close to carrying knot The root edge of the width of structure root edge and part substantially usually are exposed to whole power of such as bandage.In one embodiment, watch box Can compartment of terrain appear in precalculated position in bearing structure, reinforcer may be needed there.Bandage also can be identical at these Precalculated position use, to help fixed cargo, so that movement is reduced to minimum.In another embodiment, edge protects Body can continuously occur in the periphery of structure.In another embodiment, edge protector can continuously or intermittently occur In bottom and apical margin.According to an embodiment, edge protector can have l-shaped cross section, and can be intermittently or consecutively The periphery of the part at least a portion and width segments of the bottom of core is appeared in, to wrap up bottom at outer rim The part in face is to wind the edge and extend in a manner of covering the part in the width segments of bottom surface.According to another Embodiment, edge protector can have the cross section of the approximately C-shaped of right angle edge, and can intermittently or consecutively appear in core The periphery of a part for the bottom of body, width segments and top, with the part at the close outer rim of cladding bottom surface to wind The edge simultaneously extends in a manner of cover width part and close to a part for the top surface of width segments.According to another embodiment party Formula, edge protector occur in pairs, and each have the cross section of generally L-shaped, and can be spaced or continuously occur in core Bottom, width segments and top a part around, with a parcel of a centering close to the bottom surface of outer rim a part with Wind at least a portion of a part for the edge and the width segments close to bottom side；And one centering another extension to cover The mode of a part for a part and the top surface for closing on width segments in the width segments of the close top surface of lid.

In one embodiment, edge protector can be present on core before core is covered with polymer sheet.One Aspect, core can be retracted, to accommodate one or more watch boxes, so that one or more watch boxes are flushed with the remaining part of core, so Sheet material can cover the core with one or more watch boxes, just as watch box is not present.On the other hand, core can be retracted but deficiency To accommodate the whole thickness of one or more watch boxes, so after being covered with sheet material, there is place and might have slight protuberance in watch box. Slight protuberance as indicator or how positioning holding device.In another embodiment, watch box can be in core by one Or added after multiple polymer sheet coverings, and can flush or stretch out slight grand to be formed with the remainder of bearing structure Rise.

When watch box with polymer sheet cover core before be added when, core can be retracted (as described above), and with gather It may be not easy to distinguish watch box after compound sheet material covering core.In the example similar with these, some guide features may alternatively appear in In bearing structure, preferably to position holding feature, such as the bandage fixed for cargo.Guide features may include mark, light Micro- protuberance, projection or ridge, preferably to limit bandage position.

Watch box can by any polymer or metal material or they be bonded, can be easy molding or casting Into desired shape and be rigid (substantially rigid) or with sufficient intensity edge.In one embodiment, When watch box is occurring before core is covered with one or more polymer sheets, watch box can be by identical with sheet material or with similar The material of adhesive property is made, and sheet material and/or core are bonded under the tack temperature of sheet material to core to help watch box.So And as described above, watch box can still be adhered to the outer rim of sheet material using seal feature made of other materials.At another In embodiment, when being added to bearing structure after watch box is bonded to core in one or more sheet materials, watch box, which can be used, appoints What material.

To help watch box being maintained on core before bonding or in adhesion process, it is possible to use cohesive material (such as it is viscous Mixture or two-sided tape).The example of adhesive may include contact adhesive, such as hot melt pressure sensitive adhesive or non-melt pressure sensitive Adhesive.The example of two-sided tape may include double-sided pressure-sensitive adhesive adhesive tape, for example, two-sided melt pressure sensitive adhesive tape or two-sided Non- melt pressure sensitive adhesive tape.The thickness of adhesive or adhesive tape can be very thin so that it does not form the thickness of edge protector substantially Degree.In some embodiments, adhesive or adhesive tape can melt substantially in adhesion process.

After watch box appears in adhesion process, in order to firmly fix edge protector, construction adhesive, example can be used As used in those in foregoing or following edge seal (edge sealing), so that edge protector is in the process of tying up In and will not fall off after tying up or mobile cargo to be fixed.

As long as providing required reinforcing to edge, watch box can have any thickness.Some materials have higher than other materials Rigidity, therefore relatively thin watch box can have enough rigidity.Those more flexible, thicker components may be needed to provide enough firm Degree or intensity, to sustain the power of any cargo securing device of such as bandage etc.

Edge protector can be located at any position in bearing structure, include the position where this feature.In an implementation In mode, this feature and watch box can core and polymer sheet either film combination or using polymer sheet or It is additional before film covering core.In another embodiment, this feature and watch box can in core and polymer sheet or Person's film combination is either using additional after polymer sheet or film covering core., can be in core in further embodiment Body and polymer sheet either film combination or using additional this feature before polymer sheet or film covering core, and Watch box can be added after which., can be in core and polymer sheet or film combination in another embodiment again Either using additional this feature after polymer sheet or film covering core, and watch box can be added before it.

Edge protector can be manufactured by moulding or casting.In one embodiment, edge protector can be made in batches Make, be then cut into certain size.In another embodiment, edge protector can be separately manufactured as one or more Size.

In general, the intensity for improving the weight of carrying and improving edge at the same time is desired.The present invention includes can be with Include the feature of roughening edge (such as jagged edges, such as jagged edge) part.The roughening edge can be with polymerizeing Thing core is integral.This is different from edge protector recited above, and the edge protector is not integral with polymer core, but It is attached to polymer core.

Roughening marginal portion can reside on core, and can be combined with one or more polymer sheets Retain shape afterwards.In general, the roughening marginal portion can be formed on core during core is formed, Huo Zheke To be introduced after core is made.

In one embodiment, roughening marginal portion can reside in the width segments of connection top side and bottom side At least on root edge.In another embodiment, roughening marginal portion can reside in appointing along the width segments f of core Meaning position.As described above, roughening marginal portion can continuously or discontinuously be deposited along the width segments of connection top side and bottom side .Although material existing for the core with roughening marginal portion is less, due to being roughened edge of the edge from core Some indented regions are provided, the edge of obtained core surprisingly relatively surrounding there can be the core of planar edge more By force.

The jagged edges part of the tooth with random length and shape, such as sawtooth can be included by being roughened marginal portion Shape structure division or similar structures.In one embodiment, the end of tooth can be substantially smooth.In another implementation In mode, the end of tooth can be somewhat prominent.The length of each tooth can be substantially the thickness of border width, or base It is a half thickness of border width in sheet, or the length of each tooth can be between above-mentioned half length and whole length Random length.In addition, as described above, roughening marginal portion will not be than not being roughened marginal portion further from the side of core It is prominent.

Certain length can be extended along the edge of core by being roughened marginal portion, be not roughened therebetween or edge part Divide and interrupt.In one embodiment, roughening marginal portion can exist along two parallel sides of core.At another In embodiment, roughening marginal portion can exist along all sides of core.In the presence of the side along core, this is coarse Changing marginal portion can continuously or discontinuously exist along the side.

As described above, no matter with or without edge protector or roughening edge, above-mentioned side can be used in bearing structure Edge seal.

As described above, in the case of with or without this feature or watch box, core polymerize with one or more Combination between thing sheet material can be realized by heating and pressurizeing.In some embodiments, core and thermoplastic sheets or The part that intermembranous bonding and polymer sheet or intermembranous bonding generally comprise the core for closing on its surface polymerize with closing on The part of thing sheet surface fully bonds, or a polymer sheet on its neighbouring surface part with closing on its surface The part of second polymer sheet material fully bonds, so that the trial of two components of any separation will not generally cause the complete of component It is fully separating, but may result in some cohesion failures adjacent to border face.Usually occur for manufacturing this adhesion process At relatively high temperature, such as, it is sufficient to soften the temperature of polymeric material.The temperature, which additionally depends on, produces one or more The type for the polymer that sheet material uses.

When polymer core is covered by a polymer sheet, the edge of polymer sheet is by heating with pressurized adhesion extremely The surface of core.When core is covered and overlapped with the edge of two films by two polymer films, the edge of a sheet material can lead to Heating and pressurized adhesion are crossed to the surface of the second sheet material.Although sheet material is bonded to core completely or glues sheet material by adhesion process Sheet material is bonded to, but due to the flaw in for example bonding, by the perfect bonding of edge so that no adhesive or cohesion failure are appeared in and connect It is difficult on interface.In addition, can usually occur more such failures at edge, this is also attributable to repeat to grasp edge.

Either feature and sheet material or film can utilize sufficiently high heat or sufficiently high heat for this feature and core Bonded with pressure, to obtain basic overall bearing structure.The downside of bearing structure with eigen is substantially smooth , there is minimum protrusion, as previously described.

When polymer core is covered by a polymer sheet or film, appointing for film can be repaired after adhesion process What unbonded part.When core is covered with two polymer films and the edge of two films is overlapped, can be repaired and removed Any unbonded part of two films.However, general finishing processing may and be not efficient enough, to cut the unbonded of requirement completely Part.The some parts of unbonded edge are retained in bearing structure.For example, for two polymer to be bonded at edge Film, the marginal portion of non-good bond can be trimmed to as far as possible close to cementing line, but may not necessarily without excessive cost or consideration Enough by all unbonded trimmed aways.Core is bonded to for a film, unbonded trimmed away is equally difficult.This Outside, it is such as above-mentioned although good bonding between core and polymer film or between two polymer films, for example, it may be difficult to bond completely Edge, may be due to for example repeating to grasp appointing for adhesive or adhesion caused by edge at interface so as to need not trim Some flaws or cohesion failure in how destroying and/or bonding also usually occur more in edge.

There is the embodiment for folding edge for polymer film or sheet material, folding part is edge, although and may not have Trimmed, some flaws still occur in edge bonding is folded.

When one or more face is bonded together, one or more face is more smooth or more flat, more can be with Less defect forms more intact bonding.In the case where being not intended to be limited by theory, thus it is speculated that although make core and/or One or more face of person's polymer sheet is smooth as homogeneously as possible, but this of core and/or polymer sheet one A or multiple faces still can be uneven, and therefore, there may be defect in bonding, unless taking costliness or special The step of, so that one or more face is smooth.After completing manufacture core and/or sheet material, make the easy of smooth surface Mode can be heated to surface to be up to enough the temperature for making melt surface so that melted material can flow, with covering Make this and/or multiple faces are uneven or rough defect.So the processing of high-temperature may unnecessarily be broken Bad core and/or sheet material.

When in the core for leaving edge, either there are this defect or uneven on one or more surface of sheet material When, moisture, dust and/or from the product that previous cargo is left and on moisture, dust or the product left from previous cargo The bacterium of growth can not possibly gather because these surfaces exposed to moisture, dust and/or the product left from previous cargo with And in moisture, dust or the bacterium grown from the product that previous cargo is left.However, any such defect of edge is more It may attract moisture, dust and/or leave product from previous cargo, by moisture, dust or the bacterium for leaving product production With moisture, dust and/or leave product and bacterium may be easier to gather in perimeter, and be once retained on product Become more difficult to once remove totally, because accumulation is more or less hiding.This may result in contamination of products or at least hands over Fork pollution, and if the structure is reused be used for different from previous cargo cargo (such as different food species, Such as poultry, fresh vegetables, fresh fruit) or even same type product, carrying out strong purification also can cause load-bearing surface to weigh Multiple use or reuse are dangerous.The new bearer structure for even not covering or not storing suitably before use can easily get dirty Dye or infection.Therefore, these hidden areas eliminate pollution or experience pollutant be to cargo it is important, such as food and medicine, The product of electronic product or any contaminated exposed surface of meeting.

In an illustrative embodiments, sealing fluid can be used.Core is capped and is bonded by one or more sheet materials Afterwards, which can be used for the overlapping edge of the border face between core and sheet material or multiple sheet materials.Sealing fluid can be any incites somebody to action Polymeric material (or the multiple polymeric materials) softening in the border face between sheet material and core or multiple sheet materials is dissolved into To a certain degree to promote each component in the liquid of edge good bond.It is expected in a controlled manner or dosage distributes and application Sealing fluid so that the waste of overflow or drippage or liquid minimizes or minimizes the excessive dissolving of material on border face, for example, By using injector type distributor or other metering devices.Whatsoever distributor, the front tip of distributor, such as Hole, has small cross section, such as has just been enough in liquid to be allocated.Sealing fluid can be active at room temperature.Pass through Outer rim to one or more sheet material or the core to carry out this sealing apply the liquid, can also be glued by sheet material Before closing core or another sheet material, sealing fluid is applied.
