The specific embodiment

Common metal beverage can 1 is illustrated among Fig. 1, and is typically formed by cylinder body part with integrally formed main body 2 and lid closure 3." constriction " afterwards but the base portion 2 of the jar before loam cake is being installed be illustrated among Fig. 2 separately.Such base portion can and be squeezed by drawing and is pulled through the journey manufacturing.

In beverage can according to the present invention, can use the conventional body shown in Fig. 2.In addition, deformable bag 4 is inserted in the main body.Bag like this is illustrated among Fig. 3, is in expansion or expanded configuration.For example, bag is made by metallic paper or silver-plated plastics, and when being in expanded configuration, has meet bottom shape basic and is cylindrical shape.Bag 4 has bottom and circular open in the top.As shown in Figure 3, depression 5 is arranged on the outside face of bag.Fig. 4 illustrates depression 5 possible hexagonal structure (depression can by than more closely separating shown in the figure).Depression can integrally form with bag material, perhaps can use the form of little spacer element to be fixed or adheres on bag surface.The possible material of separation pig is the sort of (referring to the following further details) that is called as aerogel.

At production period, coated with adhesives 6 around the border circular areas of " neck " of can body 2.A spot of adhesives 6 also is placed on the inside face of bottom.This is shown in Figure 5.Under deflated state, bag 4 is inserted in the can body 2.Use pressurized air that bag 4 is expanded then.(alternately, bag can be constructed by the mode with its self-expanding.) this exerts pressure to bag 4, and it is contacted with the inwall of can body.Even pressure makes the zone between the depression also contact the bottom.In adhesive coated regions, between bag 4 and can body 2, form sealing then.Can strengthen sealing by exerting pressure and/or heat around neck region.Reduce air pressure then, bag is slightly lax as a result, forms vacuum in the space between bag and can body.Yet because the pressure of the partial vacuum that produces in the space between bag and can body, bag 4 still keeps cylindrical shape.Depression 5 guarantees that such space exists, and bag 4 and can body not each other large tracts of land contact.

Fig. 6 illustrates the bag 7 that can use in alternative production process.Not in adiabatic space, to form vacuum, but valve 8 is provided in bag, allow bag to be inserted in the can body, to seal and to deflate like this by valve by expanding bag.This makes and is pulled outwardly bag, so that the inwall of depression contact can body.The space that part is found time keeps getting off.

In another alternative production process, can between bag and bottom, form partial vacuum by deposition oxygen removing bead or powder (getter MAT'L) in intermediate space.This can be iron powder filler (being included in the pouch).This can have widely in manufacturing is used for the partial vacuum of drinking container of contents of thermally insulated container uses.

The known liquid container of from cold storage plant, removing, only be stored in insulation can or for example other special design of polystyrene storage tank device protect their contents not to be subjected in the device of external heat environmental concerns, could keep their lower temperature.Use container as described here, liquid container can be stored in the cold storage plant, remove and when keeping its low temperature, in that the time is used (just drinking up for beverage) contents after a while.Therefore further, this container can be constructed to the size identical with existing container, does not need to redesign the outward appearance of container or the coalignment of automatic vending machine for example.

Except that these advantages, this container can also be manufactured to and seem basic identical with the common metal beverage can.This will reduce the customer to introducing the resistance of new product.Another advantage is that the sensation of this container will be similar to conventional vessel, and will be the person that passs the drink as mentioned above more can be good than the taste and the sensation of plastics, pleasant metal sensation on tongue and the lip.Also advantage is metal outer and plastics inner combination will provide eco-friendly jar that can reuse.

Be suitable for forming the thermal insulating material 101 of drinking container (perhaps really be suitable for realizing packing container for example, be provided for some other adiabatic function of the adiabatic layer etc. of clothes) shown in Fig. 7.This material comprises the ground floor 102 that forms with PET (polyethylene terephthalate) film 103, has about 0.5mm or littler gross thickness.First side of film 103 is coated with PVdC coating 104, and second side is coated with aluminium lamination 105 simultaneously, for example adopts evaporating deposition technique.The essentially identical second layer 106 of structure is relative with ground floor 102, and double-ply aluminium coated side is all inside.For keep between two-layer predetermined interval, spacer element 107 arrays be attached in these layers one deck or two-layer on.It is spherical that the shape of element 107 is generally, and the diameter with 1mm level.These elements are for example to have material space than about 90% or better have very highly porous material and form.A kind of suitable material is the sort of aerogel that is known as, for example by Cabot Corporation (Cabot Corporation) with trade mark Nanogel ^TMFollowing supply the sort of.Carefully select the sphere gap of element arrays and diameter recently keeps material under usage condition integraty (vide infra).The gross thickness of material arrives the 1.5mm level 1.

Although the thermal insulating material shown in Fig. 7 only comprises single layer of spacer elements 107, alternative material structure can use element to be positioned at the multilayer of top of each other.Can use suitable bonding that spacer element is combined, prevent that them from moving around between plastic flagstone 102,106.In another embodiment, the space between the plastic flagstone can be full of with the aerogel powder that for example forms by crushing aerogel ball substantially.It will be understood to those of skill in the art that the material 101 shown in Fig. 7 can use any one formation in the multiple manufacturing process.As shown in Figure 8, cut out first and second layer 102,106 a kind of the comprising in these processes from single preforming material elongation plate.Ground floor in these layers 102 is transmitted along the belt conveyor below the hollowing 109 of rotation 108 then.Drum has been filled the spacer element 107 that applies with adhesives.Drum 109 is covered with the regular array (Fig. 8 only shows the minority hole for purpose of explanation) in the hole 110 that only is a bit larger tham spacer element 107.Except that the slit that passes the drum bottom, the protective device (not shown) is parallel to bulging axle and surrounds drum 109.This prevents that spacer element is by directly falling through the hole in the drum the hole above the slit except that those.Along with the rotation of drum 109, spacer element 107 is fallen on the surface that layer 102 aluminium applies by hole 110 and slit.The viscosity of adhesives prevents element 107 roll-away positions.The second layer 106 contacts its surface with the element coated of ground floor 102 by the cylinder (not shown) then.The material that forms is transmitted by warm air dryer (not shown) then now, and consequently dry adhesive under the situation of not damaging material is fixed on the separation pig two-layer.

In case be produced, just found time substantially in the space between the layer 102,106 of thermal insulating material.This can finish at the edge of leakproofing material by the space of finding time simultaneously by the part and the part of cutting that material are cut into suitable shape.This process can also comprise for example centre portion of leakproofing material, so that material is divided into the part of the isolation of rule.These parts can have 1cm ²Area.This structure has increased the integraty of material, thus the leakage in part will be not can the whole cutting plate of appreciable impact heat-insulating property.

Other method of making this material is:

1) use is similar to aforesaid drum, and coated layer is transmitted on the top of drum.Inside to the drum on the surface with regular array of being dug out the hole applies negative pressure, and the diameter in this hole is slightly smaller than the diameter of spacer element.Element is drawn onto in the hole by the negative pressure from sucker, is coated with adhesives on the surface that expose their outsides.Through the place above the drum, outstanding element adheres to drum and goes up and removed from the hole at plastic layer.The rotative speed of drum and the transmission speed of plastic layer, the size of the hole array in drum determines element to be placed to the lip-deep interval of plastic layer.

2) adhesive spots is printed on the surface of plastic layer with coated spacer element.This layer transmitted the dish that adheres to the element on the adhesive spots then.Before on the ground floor that second plastic layer is placed on element coated, second plastic layer can be in its whole surface coating with adhesives.

3) to be similar to the mode of using in photoprinter or the laser printer, can be charge pattern " printing " to going on the coated layer.Before the surface that is applied to layer, spacer element is coated with adhesives and be recharged.Element will trend towards only adhering on the charging zone.Can strengthen this process by layer transmission on tray of elements, so that separation pig is attracted on the charging zone upwards.

4) spread on the plate with a side of adhesives coating plastic plate, and spacer element.Then second plate is placed on above the spacer element.

Drinking container 114 is illustrated among Fig. 9, and it is formed by three major parts.In these parts first is the basic cylindrical metal outer container 115 (for example with formation such as aluminium, steel) that is, has an end and the open other end by integrally formed base seal.Container 114 is basic identical with the base portion of conventional beverage jar.Such can body and their manufacturing technology (for example drawing and crowded drawing) are known.Here only difference of Zhu Yiing is the shape of the bottom 116 of outer container 115.The bottom of conventional can main body is for being resisted the recessed cheese of the internal pressure that is produced by soda by setting.Because the use of the deformable plastic (waiting to illustrate) that inserts, the bottom of outer container can be flat substantially, allows the inner space of drinking container to be maximized.

Second major part of drinking container is an endogenous pyrogen 117.This is formed on the plastics embolus that is inserted in the manufacturing process in the outer container 115.The general shape of endogenous pyrogen 117 and outer container basic identical has an open end and by the other end of base seal.Endogenous pyrogen 117 is used the material manufacture with reference to Fig. 7 explanation, and its shape meets the shape of outer container 115 substantially.The inside face of the outside face contact outer container of endogenous pyrogen.Endogenous pyrogen by or near the open end of endogenous pyrogen, around its whole circumference, be fixed on the outer container.

Be generally the circular crown cap with downward outer rim 118, also basic for having the conventional structure of the easy-to-draw ring-like opening mechanism that is formed on the there, be placed on the open end of outer container 115 and be fixed to the there and come closed container.Lid 118 is typically used adhesives to exert pressure around the outer rim of lid simultaneously, promptly is called the process of " constriction " in the industry, fixes.Usually carry out the step of fixed cap after with required beverage filling containers.As fruit beverage is pressurization, and fixing step also must be carried out under pressure so.Preferably, endogenous pyrogen 117 extends to and covers 118 tops that are sealed to the loca of outer container 115.

Should be appreciated that outer container 105 inserts in the outer container 102 and reduced the inner space that can be used for drinks.Yet compared with the recessed cheese bottom of conventional can, this influence can be alleviated by the flat bottom of container.

When container only is filled liquid to the level at the top that is not higher than endogenous pyrogen 117, the thermal insulation of the contents of drinking container will be actv..Therefore when being cooled, the air in the gap will provide the adiabatic layer between contents and the lid in the above, reduce otherwise the heat transfer rate of conduction in may the zone of faster heating.

In a kind of modification to illustrated present embodiment, thermal insulating material can comprise for example continuous substantially bottom plate or the layer of the high aerated materials of aerogel.Plate can be applied on one or both sides by metal level and the plastic layer with for example aluminium.A kind of particularly advantageous manufacture method is in a vacuum with plastics or washing bottom plate, and in this process, the space between the bottom plate is evacuated.The coating of back seals this vacuum.In a kind of process of modification, bottom plate is at first coated with plastic layer.This plate laser beam perforation then, then plate by under vacuum coated with metal.The space in the bottom plate that helps to find time, hole.

Figure 10 and 11 illustrates the another embodiment of insulated beverage container 201, comprises by for example aluminium or stainless metal cylindrical outer wall 202.Container 201 further comprises second cylindrical wall, 203, the second cylindrical walls 203 typically by making with outer wall 202 identical materials, and is arranged in the inwall by coaxial, so that has little space between two walls 202,203.Inwall 203 can have the rib 204 of spiral extension on its outer surface, so that the inside face of rib contact outer wall 202, thus the intensity of interval between the maintenance wall and increase container.Alternately, can be in manufacturing process the plastics stripper loop be inserted into and keeps between the inner and outer wall at interval.

The top of container and bottom are respectively by top end and bottom end 205,206 sealings to make with sidewall 202,203 identical materials.For example via drawing with squeeze and to be pulled through journey, one or two that bottom end 205 can be in cylindrical side wall 202,203 integrally forms.After beverage was full of container, top end 206 typically was added on the side.Top wall and sidewall all are single-wall structures.

In the process of structure and assembling container, between outer wall 202 and inwall 203, form partial vacuum.Vacuum will be the contents 208 and external environment condition thermal insulation of container.Outer wall 202 and inwall 203 converge at the top 205 of container, form the sealing around the whole upper limb of two walls in the intersection, to keep vacuum.Vacuum is extended around the whole side of container the thermal insulation of container.

The top end 205 of container 201 is equipped with conventional easy-to-draw ring-like opening mechanism, this machine enough use the pull-tab parts and form between the wall of container on every side easily unload sealing, sealing for example forms by pushing wall with the formation instrument of unitor shape.In fact, entire top end 205 can be conventional structure.

The design of another kind of drinking container 301 is illustrated in Figure 12 and 13, and it is formed by three major parts.In these parts first is the basic cylindrical metal outer container 302 (for example with formation such as aluminium, steel) that is, has an end and the open other end with integrally formed base seal, and this can be basic identical with the base portion of conventional beverage jar.Such can body and their manufacturing technology (for example drawing and crowded drawing) are known.Here only difference of Zhu Yiing is the shape of the bottom 303 of outer container 302.The bottom of conventional can main body is for being resisted the recessed cheese of the internal pressure that is produced by soda by setting.Because the use of the plastics (waiting to illustrate) that insert, the bottom of outer container can be flat substantially, allows the inner space of drinking container to be maximized.

Second major part of drinking container is an endogenous pyrogen 305.This is formed on the plastics embolus (for example polypropylene, PTFE etc.) that is inserted into outer container 302 in the manufacturing process.The general shape and the outer container of endogenous pyrogen 305 are basic identical, have an open end and by the other end of base seal.Yet shown in Figure 12 and 13, endogenous pyrogen is a double-walled, has wall 306,307, and except that around the opening on two walls are sealed together, wall 306,307 is separated out 1-2mm.Space 304 can be by being kept by the separation pig of suitable setting.In the manufacturing process of endogenous pyrogen, extract vacuum out in the space between two walls 306,307.Manufacturing process typically is for example molding process of hollow injection molded process.One side of endogenous pyrogen or many sides can for example be come metallizing with aluminium, with the heat reflectivity of increase wall, and increase the gas impermeability, and the obstacle to getter action (vide infra) is provided.

Endogenous pyrogen 305 is inserted in the outer container, the size that both had makes and form compression or interference fit between the two, prevent the finite space (behind filling containers, vide infra) that relative motion between these two parts provides the fluid in space internally to enter.Tangible gap among the figure between the container 302,305 only is used for illustration purpose.Container under this state typically be provided for selected beverage be filled into container (to or near the top of endogenous pyrogen 305) " bottle filling machine ".If essential, this step is carried out under pressure.Be generally the circular crown cap with downward outer rim 308, be placed on the open end of outer container 302 also substantially, and be fixed to the there and come closed container for having the conventional structure of the easy-to-draw ring-like opening mechanism that is formed on the there.Lid 308 is exerted pressure by the outer rim that is typically used adhesives to center on lid simultaneously and is fixed.As fruit beverage is pressurization, and the step of fixed cap also must be carried out under pressure so.

Preferably, endogenous pyrogen 305 extends to and covers 308 tops of point that are sealed to the place of outer container 302.Because this offers the thermal insulation of the contents of container with maximization, so it is favourable.This is with shown in Figure 14, and wherein outer container is marked as " A ", and the inwall that the outer wall of endogenous pyrogen is marked as " B " and endogenous pyrogen is marked as " C ".Yet if see from the viewpoint of making and to need, endogenous pyrogen 305 can stop under " constriction " junction so.This embodiment is illustrated among Figure 15.

Endogenous pyrogen 305 forms with rigidity or semi-rigid plastic material.So, it has increased the intensity of drinking container significantly.The wall of supposing outer container 302 no longer must the identical internal pressure of opposing, and it is thinner that the significant advantage of this feature is that they can be done than conventional beverage jar.Suppose that the cost of plastic inner container is significantly less than the cost of outer container, this will cause the saving of manufacturer's cost.In addition, because plastics are light more a lot of than metal, the total weight of new Vessel Design can be less than the weight of common metal jar.

Should be appreciated that outer container 305 inserts in the outer container 302 and reduced the inner space that can be used for drinks.Yet compared with the recessed cheese bottom of conventional can, this influence can be alleviated by the flat bottom of container.

As shown in figure 13, can be coaxially form groove 309 along the length direction of each wall of endogenous pyrogen 305.Air can be along its passage that flows when this groove was provided at endogenous pyrogen 305 and is pushed in the outer container, thereby made insertion process easier, and avoided because the pressure accumulated damage that causes.

Aforesaid container will have and need take a long time to come contents are cooled to temperature required latent defect.This problem can be by being stored in container 401 in the electric refrigerator, is placed on the radiating block 402 to overcome.For example this piece can be an aluminum.Typically, the shape of container bottom will be recessed, and as shown in figure 16, and the bottom is a single wall.By on the upper surface of radiating block, forming the protruding projection 403 of complementary shape, be provided for forming the mode that good heat " is connected " with container bottom.Because the bottom is a single wall, contents will tend to be cooled off relatively apace.

Provide in the heat-insulating container in the space that those uses are found time, can be provided for being opened and internal pressure when being released, allow liquid to enter mode in the space of finding time between the double-walled at jar.For example, can provide valve in madial wall, this valve drops to guiding fluid when being lower than set pressure at internal pressure.Alternately, thus can be provided in pressure decay to being lower than the mode that set pressure following time breaks and allow liquid to enter the space.An advantage of this scheme is to enter liquid in the space with rapid cool metal outer container, allows the drink person to feel the liquid containing thing of feeling nice and cool.From drink person's viewpoint, this may want.

In improvement to above-mentioned thermally insulated container, can provide visual detector in the side of container, the measurement indication of temperature of the contents of container is provided, for example thermal excitation (thermochromism) material is applied at least one zone of wall of container.This is illustrated among Figure 10 with mark 209.Temperature indicator can be used for example material manufacture of liquid crystal, and wherein liquid crystal material layer is applied on the outer wall of container.Visual indication can be red in the temperature of contents in time more than 20 degrees centigrade, and can be blue in the temperature of contents in time below 12 degrees centigrade.These temperature values will change according to the temperature required scope of the contents of container.Temperature indicator provides the quantitative measurment of temperature, rather than must rely on the estimation of sense of touch qualitatively.

Can temperature indicator be designed to be synthesized at contents when the first threshold temperature is above, red speech, for example " temperature " and at contents when the second lower threshold temperature is following, blue " cold ".Alternately, indicating device can be temperature scale, to be similar to the mode of heat indicator, has the mark of indication contents temperature on scale.Indicating device can be integrated in the identification of the manufacturer or other similar design on the container outer wall.

Should be appreciated that the outer wall of container does not contact with the contents direct heat, correspondingly, temperature indicator is designed to have time delay, and this time delay calculates according to the known thermal property of the contents of container.After being removed from cold storage plant, because the vacuum insulation of contents, the outer wall of container will reach the temperature of surrounding environment with the speed faster than contents.The specific heat capacity that temperature indicator is designed to the contents of the heat transfer characteristic of temperature, container based on container outer wall and container produces the temperature measurement result of the contents of container.For example, indicating device can be indicated ambient temperature with about 8 hours delay of the contents of representing cooling tank (or heating contents after the cooling) institute's spended time.This indicating device has solved the known indicating device intrinsic problem of explanation among the GB 2334092 for example like this.

The known liquid container of from cold storage plant, removing, only be stored in insulation can or for example other special design of polystyrene storage tank device protect their contents not to be subjected in the device of external heat environmental concerns, could keep their lower temperature.Use is according to container of the present invention, and liquid container can be stored in the cold storage plant, remove, and when keeping its low temperature, in that the time is used (just drinking up) contents for beverage after a while.Therefore further, this container can be constructed to the size identical with existing container, does not need to redesign the outward appearance of container or the coalignment of automatic vending machine for example.

Except that these advantages, this container can also be manufactured to and seem basic identical with the common metal beverage can.This will reduce the customer to introducing the resistance of new product.Another advantage is that the sensation of this container will be similar to conventional vessel, and will be the person that passs the drink as mentioned above more can be good than the taste and the sensation of plastics, pleasant metal sensation on tongue and the lip.

It is a kind of under the independent heat-insulating situation of needs not that container according to the present invention provides, and liquid remained on for a long time the facilitated method of low temperature.In addition, the combination of metal outer and plastics inner will provide eco-friendly jar that can reuse.

It should be appreciated by those skilled in the art that in the case without departing from the scope of the present invention, can make various modifications the foregoing description.In one modification, in outer container, provide gap or hole, so that can see endogenous pyrogen by gap or hole.This may want for for example allowing the user to see the structure of jar and/or visual interesting advertisement being provided.In another is revised, can replace the metal outer container with glass or duroplasts or cardboard packaging.Container can be doleiform, rather than jar shape.
