Description
The present invention relates to a kind of heat-insulated container and a kind of insulation cover, for example Dewar bottle, freeze box, ice chest, heat insulation cup incubation canteen.The present invention be more particularly directed to a kind of thermally insulated synthetic resin container and a kind of thermally insulated synthetic resin lid, in a double-walled container or a wall container, have a thermal insulation layer, fill gas in a kind of heat-barrier material in layer with a kind of low-thermal conductivity.
The application is based on the flat 10-53978 of Japanese patent application No. No., and its content is drawn at this and is reference.
So far, as the heat-insulated container of height insulation capacity, known a kind of vacuum heat-insulation canister, this container have the outer container that an inner pressurd vessel and is made by metal (being generally stainless steel), air in the space between inner pressurd vessel and the outer container is evacuated, to obtain a vacuum heat-insulating layer.The thermal insulation layer of a kind of heat insulating metal container like this is very thin, has outstanding durability, and obtains superior heat-proof quality.
Also known a kind of thermally insulated synthetic resin container (below be called a kind of heat-barrier material heat-insulated container), wherein between an inner pressurd vessel of a synthetic resin double-walled container and an outer container, fill moulding bodies with a kind of organic foam body or a kind of rigidity urethane foam or polystyrene foam etc., or the heat-barrier material of organic foam such as a kind of pearlite.Such heat-barrier material heat-insulated container is used for, for example Dewar bottle or incubation canteen, freeze box or the like cheaply.
Having thermally insulated synthetic resin container in light weight, as to be easy to molding, low manufacture cost and other advantages is developed gradually.In these thermally insulated synthetic resin containers, a kind of heat-insulated container (hereinafter referred to as gas heat insulation type heat-insulated container) is arranged, fill the gas with the conduction of a kind of low-heat in the space between the interior outer container of a double-walled synthetic resin container, this gas is at least a kind of in xenon, krypton and the argon.
When making general heat insulating metal container, absorb intrametallic gas in order to remove, need carry out high-temperature heat treatment.Therefore the manufacturing process complicated problems occurred, for example in the vacuum seal step, therefore, manufactured very time-consuming.And, because this structure has a vacuum heat-insulating layer between inner pressurd vessel and outer container, therefore, prevent that as one radiant heat from passing the radiation measure that the vacuum heat-insulating layer between the interior outer container transmits, and must form the layer of metal paper tinsel or the coat of metal in the outer statement of inner pressurd vessel.This makes the cost of this container further increase.
And, can not carry out heating using microwave with micro-wave oven with heat insulating metal containers such as Dewar bottles.Because under the situation that a kind of beverage in container has cooled down, content must be transformed in another container, reheat with a heater then, this heater for example is a kind of light stove and accessory, and this is unsafty often in practice.
And then, under the situation of the heat-barrier material heat-insulated container of making by a kind of synthetic resin, owing to charge into the heat conductivity height of the heat-barrier material in it, in practice, in order to obtain enough heat-proof qualities, the thickness of thermal insulation layer (distance between the outer surface of inner pressurd vessel and the inner surface of outer container) must be very big.And if heat-barrier material does not charge into the narrow of thermal insulation layer, then this performance can be very not satisfactory.Therefore, in order to improve the operating efficiency that heat-barrier material charges into process, then need a thick thermal insulation layer again.As a result, the thickness of such heat-insulated container be the heat insulating metal container 5-10 doubly.Therefore, dischargeable capacity is more very poor than (internal capacity is with respect to the ratio of external container size), and it is very little to make internal capacity compare with outward appearance, and this is unsafty in practice.
And then, under a kind of situation of the gas heat insulation type heat-insulated container of making by synthetic resin, owing to will not charge into thermal insulation layer by heat-barrier material, therefore no longer need between the width of interior outer container, form the gap, so just make heat-insulated container have a big dischargeable capacity ratio.Yet, the same with the heat insulating metal container, in order to prevent to pass the transfer of radiant heat of thermal insulation layer, at least one outer surface of the inner pressurd vessel of this heat-insulated container, must form a coat of metal or a metal foil layer.Therefore, exist the problem that manufacturing cost increases.

And then heat-insulated container is to be produced by the heat-barrier material of being made by a kind of organic foam material 5 that is provided with between outer container 2 and inner pressurd vessel 3, so need not to place a radiation proof metal level (coat of metal or metal forming) on the outer surface of inner pressurd vessel 3.Therefore, can be with the low cost manufacturing.And heat-insulating property is identical with the common gas-insulated type heat-insulated container of being made by synthetic resin and have a radiation proof metal level.And then, because this structure has been saved metal level, so this heat-insulated container 1 can heat its content with micro-wave oven easily.
Form a therefrom outstanding cylindrical handle 25 from the middle body of last cover piece 23.Form a recessed portion 30, one bore portions 28 in the central authorities of handle 25 and penetrate this recessed portion 30, so that be communicated with a thermal insulation layer that fills with heat-barrier material 24.And, in recessed portion 30, also inserting one by the sealing plate made from the same synthetic material of cover piece 29, this plate is adhered to the outer surface of recessed portion 30 airtightly with a kind of adhesive or analog.Like this, sealing plate 29 just covers bore portion 28 airtightly.
Heat-barrier material 5 identical materials in heat-barrier material 24 usefulness and the heat-insulated container 1 also form with identical with it manufacture method, and this heat-barrier material is made by a kind of organic foam material with lattice structure of connection.And a kind of low heat conductivity gas body remains in the lattice of connection of heat-barrier material 24.
Utilize the step identical can be easy to and accurately make insulation cover 21 with the manufacture method of heat-insulated container 1.
Owing to fill the low heat conductivity gas body that is selected from xenon, krypton and argon with at least a in the space on insulation cover 21 between cover piece 23 and the following cover piece 22, to form thermal insulation layer 24, so it has than the much better than outstanding heat-insulating property of being made by synthetic resin of common heat-insulating material heat-insulated container.
And then because this insulation cover 21 need not providing radiation-resistant metal level on the surface of the cover piece of thermal insulation layer, the integral body of insulation cover can be made by a kind of synthetic resin, thereby can carry out heating using microwave by enough micro-wave ovens.
As shown in Figure 1, this heat insulation synthetic resin lid 21 is used with above-mentioned synthetic resin container 1, can provide the dining table vessel of low-cost and outstanding heat-insulating property, thereby the use micro-wave oven can carry out heating using microwave.
Fig. 2 illustrates one second embodiment of heat-insulated container of the present invention.
In this heat-insulated container 31, the insulator 35 of one double-walled construction is set between two walls of an inner pressurd vessel 33 and an outer container 32, this double-walled construction is formed with an outer wall spare 38 and an inwall spare 39 of the heat-barrier material 34 of planting therebetween, thereby constitutes the alms bowl of a wall structure.The heat-barrier material 34 that is arranged in the space (thermal insulation layer) between inwall spare 39 and the outer wall spare 38 is made by a kind of organic foam material, and the lattice of heat-barrier material 34 is connected to each other to the lattice of connection (also being referred to as open lattice foam or porous foam).For this material, can select the polyurethane, polyethylene, polyester or the analog that in common insulating materials heat-insulated container, are used as a kind of organic foam material for use.For manufacturing process, can adopt with first embodiment in be used for the identical a kind of method of method of heat-barrier material 5.And then, keep at least a low heat conductivity gas body that is selected from xenon, krypton and argon in the inside of the lattice of the connection of heat-barrier material 34.
The core that one groove, 42, one bore portions 40 penetrate this groove 42 is formed on the bottom at the outer surface of outer wall spare 38, so as be communicated with at the thermal insulation layer 43 that fills with heat-barrier material 34 between outer wall spare 38 and the inwall spare 39.And then, will insert grooves 42 by the sealing plate 41 that the synthetic resin material identical with outer wall spare 38 made, and be adhered to the outer surface of groove 42 by a kind of adhesive or analog airtightly.Like this, sealing plate 41 just covers bore portion 40 airtightly.
When making this heat-insulated container 31, outer container 32 forms by injection moulding or blowing with inwall spare 39 with inner pressurd vessel 33 and outer wall spare 38.To be clipped between outer wall spare 38 and the inwall spare 39 by the heat-barrier material 34 that a kind of organic foam material with lattice structure of connection is made then, and adopt welding methods such as Vibration Welding or rotating welding that outer wall marginal portion 36 and inner wall edge part 37 are connected as one.As a result, double-walled insulator 35 is made by thermal insulation layer 43, and this thermal insulation layer comprises the heat-barrier material 34 that is arranged between two walls that the outer wall spare 38 made by synthetic resin and inwall spare 39 constitute.At this moment, on bore portion 8, form the groove that aligns.If for example shown in Fig. 5 or 6, groove 11 or 12 is radial or lattice-like, then can bigger efficient vacuumize and inflate.
Then a vavuum pump is connected in the bore portion 40 of the core of the bottom that penetrates insulator 35, and the thermal insulation layer 43 between outer wall spare 38 and the inwall spare 39 is vacuumized, thereby eliminate any foamed gas (or air) that remains in the heat-barrier material 34.Because lattice belongs to connectivity structure, so, by bore portion 40 is vacuumized, can be arranged on the heat-barrier material 34 in the thermal insulation layer 43 lattice in addition thin vacuumize.After vacuumizing, a kind of low heat conductivity gas body is introduced thermal insulation layer 43, be roughly atmospheric pressure up to pressure, therefore, low heat conductivity gas can replace heat-barrier material 34 lattice in addition thin, and keep within it.
After with gas displacement, a kind of adhesive is coated on the outer surface of groove 42, a sealing plate for preparing separately 41 is inserted grooves 42, and be connected with it airtightly.As a result, made insulator 35 has the thermal insulation layer 43 that comprises material 34, and heat-barrier material 34 has the lattice structure of connection, keeps a kind of low heat conductivity gas body in the lattice, and thermal insulation layer 43 is formed between the outer wall spare of being made by synthetic resin 38 and inwall spare 39.
After this, insulator 35 is interposed between outer container 32 and the inner pressurd vessel 33, and uses a kind of Vibration Welding or the such welding method of rotating welding that one an outer container marginal portion 36 and an inner pressurd vessel marginal portion 37 are connected as one.As a result, made heat-insulated container 31 has and is arranged on the outer container 32 made by synthetic resin and the insulator 35 between the inner pressurd vessel 33.
Because inwall spare 39 and outer wall spare 38 are made by a kind of synthetic resin with outstanding gas barrier properties, so the low heat conductivity air seal can be remained on therebetween.And, since inner pressurd vessel 33 and outer container 32 employed be a kind of chemical-resistant synthetic resin that has, what can not take place in use that cleaning agent and analog cause breaks.
And then, because made heat-insulated container 33 has the heat-barrier material 34 that charges into thermal insulation layer 43, so on the outer surface of inwall spare 39 or inner pressurd vessel 33, need not to place a radiation-resistant metal level (coat of metal or metal forming).Therefore, low cost of manufacture.
And heat-insulating property can be with common by a kind of synthetic resin manufacturing and to be provided with the gas heat insulation type heat-insulated container of a radiation proof metal level identical.And then, by strong insulator 35 is set, can improve the mechanical strength of container between outer container 32 and inner pressurd vessel 33.And, because this structure has been saved metal level, so container 31 can carry out heating using microwave with a micro-wave oven to content very expediently.
Fig. 3 illustrates according to one the 3rd embodiment of a heat-insulated container of the present invention and another embodiment of an insulation cover, and it is the example of heat insulation dining table vessel, and it comprises that a heat-insulated container 61 and covers the insulation cover 51 of a upper opening of heat-insulated container 61.
Heat-insulated container 61 is a double-walled alms bowl, and it comprises an outer container 62 and an inner pressurd vessel 63.One heat-barrier material 64 is arranged between outer container 62 and the inner pressurd vessel 63, forms a thermal insulation layer 65.
Heat-barrier material 64 adopts a kind of low heat transfer gas to make, and as foamed gas, it comprised at least a in xenon, krypton and the argon when this gas was shaped.The lattice that constitutes heat-barrier material 64 has lattice structure independent of each other (sealing crystal lattice type foaming structure), is used to make the low heat transfer gas of gas foaming to be sealed in the lattice, so just obtains excellent heat insulation property.As the method for making heat-barrier material 64, the method that for example can adopt Japanese patent application to describe among the flat 7-258446 of publication number No. first it is desirable to, and makes heat-barrier material 64 form a container shapes, and can be located between outer container 62 and inner pressurd vessel 63.
