Summary of the invention
An object of the present invention is to provide a kind of package that is used for fireworks that addresses this problem.In order to reach this purpose, packages in accordance with the invention is a feature with the described structure of claim 1.
By making package be provided with opening at least partly, emergent flame can spread in the package fast, and lights the fireworks that are stored in wherein.Therefore, described package purpose does not also lie in ground as well as possible and/or covers fireworks as far as possible longways, but with noted earlier opposite, light fireworks as quickly as possible, avoiding uncertain, potential blast situation, and can stop over the fire extinguishing operation necessarily.Importantly realize lighting fireworks here with the controollable secured fashion.Realize this purpose according to the present invention as getting off, promptly described package surrounds fireworks in all sides, and is made by heat proof material, even make at high temperature that like this this package also has enough intensity that the fireworks that react are kept together.The pressure wave that produces in blast process can be overflowed from described package via described opening, thereby makes the pressure in the package steady, and can not make unnecessarily bearing load of package.In addition, described opening helps to reduce the weight of package, and this is especially favourable when described package is used as transport package and is used.
With regard to heat proof material, can use metal, especially corrosion-resistant steel.This material can at high temperature keep its intensity.Yet the other materials of dipping or coating fire-proofing chemical is also eligible alternatively, the plastic refractory that comes out for example newly developed.The particularly important is, the expection high temperature that produces during the employed material going fire is wanted down to keep enough intensity.An advantage of plastics is its relatively light and processing easily.
In a preferred embodiment, packages in accordance with the invention is a feature with the described structure of claim 3.
Described package is preferably made by three-dimensional frame, is coated with the relatively thin cope that is provided with opening on this frame.This cope can keep together the fireworks of burning, and the power of following simultaneously can be delivered on the relatively harder frame, and this frame is preferably designed to a rigidity, reticulation basket structure, and by various piece for example casket shape part institute formed.In this way, on the one hand package can realize that enough intensity resists the power that the fireworks explosion time discharges, and it is also very light on the other hand.
Cope for example can be gauze or perforated sheet metal.The advantage of net is that the cost of price aspect has advantage and very light, and as described, when this package was used as the transportation purpose, net especially had advantage.Therefore on the contrary, perforated sheet metal is bigger than the rigidity and the intensity of net, and when being more suitable for need the fireworks that relative power is bigger keeping together.Certainly, frame also can be respectively by different material manufacture with cope.
The opening of cope can have Any shape.When using perforated sheet metal, perforation preferably has the shape of rounding, and is especially oval or circular.In this way, can avoid the local peaking's pressure in the material, this local peaking's pressure for example occurs near the angle point of rectangular aperture.Opening can for example be arranged in the material by punching simply.
In further elaboration, packages in accordance with the invention is a feature with the described structure of claim 7.
Described opening has such size, and is on the one hand sufficiently big so that flame can be promptly saturating in package and make the pressure in the package steady, sufficiently little on the other hand, so that the fireworks of burning part can keep together.
In further elaboration, packages in accordance with the invention is a feature with the described structure of claim 8.
As the occupied surface of the opening of an all surfaces part, should not select too greatly on the one hand, because will greatly weakening, this will finish the package that makes the task that fireworks partly keep together.On the other hand, this part is preferably big as much as possible, can obtain unlimited relatively light package like this, and the possibility that it has well and environment exchanges especially has good flame, pressure wave exchange possibility.Applicant's experiment shows, if having whole tank surface about 10%~25% between perforated surface, so just obtain good balance in the above between the demand of contradiction.Yet these values should not be regarded as determinate.They depend on other factors the fireworks kind that will pack except described package and the material (thickness, intensity) of the making described package.
In a preferred embodiment, packages in accordance with the invention is a feature with the described structure of claim 9.
In package, can for example change the shape and/or the size of described opening according to the relative position of opening in package.For example, the part of the package of maximum, force is in use born in expectation, relatively little opening can be set, so that can weaken these parts necessarily; Perhaps in use be difficult to the part that enters, for example the bottom surface of package can be provided with relatively large opening on the contrary, so that promote the release of pressure and the circulation of flame, and thus relatively poor accesibility is remedied.
Described casing preferably is provided with shank, and surface or the casing that is positioned at below it just can be left in the bottom surface so in use, and therefore is easy to make propagation of flame.This makes can light soon at the fireworks of bottom, and the authorized pressure ripple is overflowed via the bottom surface.
In a preferred embodiment, package can be provided with the suitable interval thing, and this spacer can guarantee that described casing has a suitable distance apart between wall or another casing, so that always can enter all sides of described package well.
In a particularly preferred embodiment, described casing is provided with a lid, and at off position, this lid is contained in the upstanding sidewall of described casing suitably.Like this, describedly be stamped the rigidity that helps improve described casing, because the edge bearing of described lid is on upstanding wall and prevent that their from tilting or warpage.
Described lid preferably is locked on the casing by closing device.This has prevented that fireworks from overflowing in casing between explosion period, for example prevent also that fireworks drop out from casing when the fireworks side is placed or is placed upside down.These closing devices could manually or automatically enter latched position to this closing device of decision design when described lid correctly is placed on the casing so that have only.Further, the decision design closing device will not be so that will produce a tangible optical signal when they are in latched position or can not enter latched position.
In principle, described package can be an Any shape.For example, package can be cylindrical.For a given volume, cylindrical shape has especially favourable rigidity and intensity.Yet described package preferably is the square shape basically.Such shape can be piled up compactly.In addition, the square shape of package can be well be complementary with the shape of fireworks to be packaged, and these fireworks normally are sorted in the less rectangle consumer packages, so just can as far as possible farthest fill package.The outside dimension of package is preferably adjusted to for example size of cargo-type container or European shelf of standard conveying arrangement so that one or more package can be placed on such conveying arrangement or within.Like this, just can effectively utilize existing transportation and storage space, and help reducing traffic cost.
Space requirement when making emptying state minimizes, and packages in accordance with the invention also can be collapsible or the detouchable design, structure as claimed in claim 19.This makes package be in flat basically shape before use and/or after using, and making needs less space in the storage of package and/or (returning) transportation.
The invention further relates to a kind of method of distributing fireworks to the retailer from the storage storehouse, it is a feature with measure according to claim 24.
In this method, package is as transport package and memory storage.This provides the advantage in the logistics, and promptly fireworks only need be in Central Storage packing once, does not after this need to shift or repack delivering to the retailer place, but can send together with package.Packaging blanks can send back to Central Storage simply to utilize again, preferably makes it be in folded state, so that the space of using minimizes.
In addition, described package provides following advantage, and the fireworks that promptly are stored in wherein can be specified lower fireworks grade, and this fireworks grade does not correspondingly require to have too strict safety requirements.Like this, retailer and cargo transport merchant's existing storehouse and conveying arrangement need or do not need to adjust hardly, just satisfy the requirement of safety rule.
Further dependent claims will be described the purposes advantage and the embodiment of packages in accordance with the invention and method.
The specific embodiment
Fig. 1 has shown the package 1 that is used to store and transport fireworks according to the present invention, and this package (but not exclusively) especially is used for storing and transportation consumption fireworks; In this package, if flame, fireworks can be lighted in rapid and safe mode.In this manual, this speech of consumption fireworks is meant the relative lighter fireworks of being sold the customer by the retailer, and is arranged in less relatively consumer packages, and these packages hold selected fireworks display fireworks and/or firecrackers usually.This is opposite with professional fireworks, and these specialty fireworks have power more greatly and more.
Packages in accordance with the invention 1 comprises the casing 2 that has lid 3.In Fig. 1 and Fig. 2, omitted lid 3 in order to know, still, lid 3 will be described in more detail with reference to figure 4.Described casing 2 comprises a cage shape frame 5, and the wall of this frame and the end all are coated with perforated sheet metal 6.Frame 5 and sheet material 6 are made by heat proof material, such as metal, and corrosion-resistant steel especially.Yet frame 5 also can or apply suitable fire-proofing chemical and makes by dipping on for example timber or the plastics.Only importantly, employed material will have enough resistance to heats, keeps intensity down with the high temperature during the going fire, thereby the fireworks of blast can be kept together.
Frame 5 is made of casket shape part 7,8 upright and accumbency, and they interconnect near the end to form three-dimensional rectangular frame.This framework is further strengthened by centre portion 9, and centre portion 9 is arranged on upright and accumbency part 7,8 between, be similar to grid or stay, and offer the rigidity and the intensity of frame 5 necessity, prevent its inclination.Depend on the material of making these parts 7,8,9, these parts can by for example the welding, bonding, the riveted joint or known to similar method of attachment interconnect.
Perforated sheet metal 6 comprises a perforation plate 10 and four perforation side plates 12, in Fig. 1, in order to show following frame 5, has removed a part of side plate.The purpose of perforation is to make flame as quickly as possible thoroughly in package, and the pressure wave that allows the fireworks blast the be produced package of can overflowing.
Plate 10,12 can be connected on the frame 5 by the interconnection technique identical with technology mentioned above.In the embodiment shown, plate 10,12 is connected to the inside of frame 5, makes that cover is pressed to frame 5 when the pressure in described casing 2 between the fireworks explosion period increases.
Plate 10,12 is different mutually on thickness and perforation structure.Like this, base plate 10 has circular perforations 14, and side plate 12 is provided with oval perforation 15.In addition, base plate perforation 14 has than another 15 bigger sizes of boring a hole.Therefore like this,, guarantee that flame still can penetrate into via the side in the package 1,, and guarantee that further the pressure wave that forms can overflow via the bottom side between explosion period in the also blast apace of fireworks of bottom although the accesibility of bottom surface is relatively poor.
In order further to improve the accesibility of bottom side, package 1 preferably is provided with shank 16, and so in use base plate 10 just can leave the surface.Further, the sidewall of package 1 can be provided with the suitable interval device, and for example rib or projection make these sidewalls not interrupted like this, and wherein these sidewall sections that are provided with opening are not interrupted at least.
For example, this escapement also can be by being realized by special-shaped sheet material manufacturing base plate and/or side plate 10,12.As shown in Figure 3, base plate 10 is provided with the corrugation profile of box-shaped among the figure, and its ditch 30 is towards the outside, and its ridge 32 is towards inside.Because this profile has been arranged, air can be passed to the outside of package 1 along bottom surface 10 by the groove between the ditch 30 31, and air can be passed to the inside of package 1 along the fireworks V that is placed on the bottom surface by the groove between the ridge 32 33.Opening 14 on the base plate 10 has guaranteed that good connection is arranged between the inside and outside, makes the pressure held stationary, and allows flame to spread to inside from the outside fast, and vice versa.The additional advantage that described special-shaped sheet material provides is that it has increased the integral rigidity of package 1.
Ridge 32 and ditch 30 preferably have the incomplementarity shape, make that like this its profile is just in time interlocking not, always leaves certain clearance between the two but make when the package of two ends with identical appearance or wall is disposed opposite to each other.
The size of selection perforation 14,15 and they are the occupied surface of a plate surface part as a whole, make on the one hand perforation 14,15 want enough greatly so that flame easily by and make the pressure in the package steady, perforation is enough little on the other hand, so that hold the fireworks part of blast in interior.Should be noted that at this, the maximum of the perforation 14 in base plate 10 allows size not have the maximum of the perforation 15 on package 1 other parts to allow size important, because the fireworks part and/or the spark that leave via the bottom surface can not spread farly, and therefore can not cause dangerous to the those present.
Shown in for example, circular perforations 14 has the diameter of about 22mm, and approximate 20% base plate 10 integral surfaces that account for of perforated surface.Oval perforation 15 has the width of about 4mm, the about length of 11mm, and 15 the common surface of boring a hole account for side plate 12 integral surface about 15%.
Further, the sheet material that base plate 10 usefulness are thicker than side plate 12 is made.This can remedy the influence that weakens of relatively large perforation 14, makes base plate 10 generally speaking have at least the intensity identical with side plate 12.Preferably, select the thickness of base plate 10 to make base plate 10 even have bigger a little intensity, because in use base plate 10 will generally bear heavier load than side plate 12, this is that the fireworks weight that is placed on the base plate 10 causes.For example, base plate 10 can be made with the thick steel plate of 2mm, and the thick steel plate of side plate 12 usefulness 1mm is made.
Above-mentioned numerical value should only be used as an example, because of rather than restrictive.These numerical value (quantity of thickness of slab, material type, shape, size, perforation and position) can be different on each package, and this depends on the kind and the quantity of fireworks (fireworks display fireworks, firecrackers) therein to be packaged.Often preferably mutually adjust different numerical value, so that package obtains enough intensity so that fireworks are kept together on the one hand, and preferably light as much as possible on the other hand, this transportation function with the package expection is relevant.
The advantage that rectangular shape provided of package 1 is that it makes that package is firm and can closely stack.Preferably select the outside dimension of package 1, make one or more packages can be placed on suitably on European shelf, freight container or the similar standard conveying arrangement or within.
Fig. 2 has shown the optional embodiment of packages in accordance with the invention, have identical reference number with the corresponding part of the package among Fig. 1, and label has increased by 100.Casing 102 shown in Figure 2 comprises the cylindrical frame 105 of annular section 108, and this annular section 108 connects by upstanding portion 107 parallel to each other and that separate at interval.In inside, frame 105 is laid by gauze shape material 106 and is formed.Clearly, select this Web materials 106, can not allow the fireworks part therefrom pass through so that its grid is enough little.This Web materials is poorer than the intensity of employed sheet material among Fig. 1, still, its very light in weight, and cost is relatively low.This makes this package be particularly suitable for lesser amt and relative lighter fireworks.
Fig. 4 is an exploded drawings, has shown a lid 3 that is fit to be used for casing 2 shown in closed Fig. 1, and described casing has only shown top in Fig. 4.Shown in lid 3 comprise cover plate 22 and at least two supporting members 24 that are essentially rectangle.
