Abstract

A container comprises the double layer of side walls, a container cover and a base plate. The container is in a shape of a hollow assembly which comprises the rectangular base plate. The cover portion and the base plate are connected into a whole, the cover portion extends out of the base plate, and the double layer of side walls are folded along thinning lines and welded on the corner edges to form the container. The space which is formed by the base plate of the container, the double layer of side walls and the container cover is filled with gas. The base plate is provided with a draining device. The production of the thinning lines includes that one side of the hollow assembly, which forms the inner side of the container, is provided with V-shaped grooves and the edges which protrude towards the inner space are formed after folding.

Description

A kind of container

Technical field

The present invention relates to container, in particular for the container with all fresh goods of transportation.

Background technology

The container of the fresh and alive goods and materials such as existing fish transport shellfish is generally used for example foamed plastic manufacture of polystyrene and so on.But this class structure of container poor performance, deposits or carries often and damage, and result is by cargo damage, so that may cause economic loss.

In order to discharge liquid, on the limit of foam plastics container bottom, establish through hole.These holes can not solve such as the problem of environmental pollution in warehouse and cargo hold.As for air transport, goods will be packed with water-proof container, and the material of high-hydroscopicity energy must be set up in bottom.This extra packing increases cost of transportation, because transportation volume reduces (because volume increases) and must pack with foam plastics container overline.In addition, the eyelet of foam plastics container reduces heat insulation capacity.

Summary of the invention

The object of the invention is to, propose a kind of container that transports fresh goods, can address the above problem, and have good heat-insulating property and structural behaviour, productive costs is low, can reduce cost of transportation etc.

The invention provides a kind of container, comprise double side walls, jar and base plate, container shapes is hollow assembly, comprise a rectangular base plate, cover portion and base plate are linked to be integral body and are overhanging from base plate, by sidewall is welded and makes container forming along attenuate line folding and on the edge of angle, the base plate of container, aerification in the space that sidewall and cover surround, base plate is provided with pumping equipment, being made as in a side of hollow module composition container inner wall of attenuate line, makes V-shaped groove, becomes the outstanding rib in inside space after folding.

The present invention also comprises a kind of method of producing hollow assembly, and the thermoplastic material manufacture of hollow assembly is produced with blow moulding, comprising: a) by an annular nozzle, push, form flexible pipe;

B) by pressurized air, press at once the size inflation of final products;

C) then by the flexible pipe pressurization of inflation, for example, between two rollers, be pressed into flat hollow object;

D) be finally transported between two moulds, form the correct shape of hollow assembly, reach after net shape excision around the excess stock at hollow assembly edge.

The specific embodiment

In the present invention, container has hollow double side walls, and roof and base structure wherein have inner side wall plate 17,18, and 19 and outside wallboard 20,21,22, as Figure 1-3.High density polyethylene (HDPE) or similar thermoplastic material manufacture for container.Distance piece 23 isolation for inner and outer plates form when hollow assembly 2 is manufactured.Separator strengthens the bus structure of container, increases its impregnability and mechanical strength.The quantity of distance piece depends on the material of use and cuts lotus.

Tank top plate 19 is provided with drainage channel.As Figure 1-4, drainage channel extending longitudinally.But drainage channel equally can be laterally or star formula stretch, groove all leads to the center of container.And, in the nearly center of groove 24 bottoms, be provided with drain gutter 25.The watery blood that frozen water bottom flowing to and wet cargo ooze out is passed groove 24 and carries, and enters the space 9 of the double bottom of container through drain gutter 25.In addition, between the space of bottom and sidewall spaces 8, having form is hole 26 the two is connected, and when the canting of goods container, the draining in bottom space 9 can flow to the lowest part of sidewall spaces 8.Above-mentioned arrangement pollution abatement problem to greatest extent, prevents draining contact goods.

A kind of anti fouling composition can be added or Injection Space 9 in addition, to reduce and even finally to prevent the breeding of bacterium in exudation.

On the upside of cover, arrange protruding head 29, on bottom side, bottom, arrange depression 30.Protruding head 29 is inserted depression 30, and the goods container on upper strata can be firmly connected with other similar goods containers.In the present invention, every end of container also separately has depression to can be used as handle.

Referring to Fig. 4 and 5, it is basis that the shape of container be take out of the void heart assembly 2.Hollow assembly 2 has rectangular base 3, forms container bottom; Sidepiece 4 and cover portion 6, be connected with bottom 3, from bottom, stretches out, and respectively stretches out one in the outer rim of bottom.In Fig. 4, cover and hollow assembly 2 integrated connections.But, also cover and assembly can be made respectively.

The moulding of container is that sidepiece is upwards rolled over along the line 5 of attenuate, then by welding each sidepiece is connected on the edge of angle.The formation of attenuate line, is in the inboard side of the hollow assembly of container, and V-shaped groove 28 is set, and after folding,, after container forming, becomes the fin 27 that stretches into space 8,9.

Container forming equipment can conveniently be established and be placed on place to use.Thereby can greatly reduce the cost of transportation of packing, because packing can be done to heart assembly transportation out of the void, and not make the container traffic after bulky use,

Fig. 6 shows the main method of producing hollow assembly.Production facilities has an extrusion molding apparatus 32, pressurized air supply line 33, pressure roller 14 and groove tool 15,16.The plastics slurry of manufacturing hollow assembly is pushed by extrusion equipment 32.By the flexible pipe of making 11, use at once the pressurized air of passing through from nozzle and pipe 33 to expand, expand size 12 to.By the flexible pipe 12 of inflation, further in 14 conveyings of roller, part is pressed into flat " flexible pipe " 13.Then flat flexible pipe 13 is transported to pressurization between mould 15,16, obtains the net shape of hollow assembly 2. Mould 15,16 is established cooling, the equipment such as welding and cutting.

In the forming process of hollow assembly 2, the upper lower wall of flat flexible pipe 13, owing to there being interior pressure, leans against respectively on the shaping wall of the upper and lower forming section 15 of mould and 16.By the bead welding around hollow assembly 2, excise outwardly directed material simultaneously.
