Below with reference to a kind of beverage can explanation the present invention from heating or cooling.Yet the cover of the present invention that the following describes separates when requiring packing first and second materials to make that they begin, and in the situation of mixing in use afterwards, general purposes is arranged.In general, first and second materials are the materials that are easy to chemical reaction.

Beverage can shown in Fig. 1 can be the beverage can 10 of metallo-or plastics, and it has the outer wall 12 of an end by a substantially cylindrical of top member 14 osed tops.As illustrating in WO96/29255, the bottom parts 16 of jar is recessed to be limited to long exocoels 20 that extend in the outer wall 12.The outer wall 12, top and the

bottom parts

14 and 16 that should be understood that jar limit an inner chamber 22, the beverage of packing into therein together.Can see, exocoel 20 extends in inner chamber 22, and the wall by bottom parts 16 between them separates.

The structure of jar 10 shown in Figure 1 is arranged to and the conventional identical size and dimension of beverage can.This means that this jar can canned and processing on existing canned line.

Utilize jars 10 exocoel 20 a kind of first reaction material of packing into.At jar is during from heating tank, and chamber 20 usefulness quick limes (calcium oxide) are filled.The chamber 20 of quick lime pack into by cover of the present invention 30 sealings.To the jar that heats certainly, this cover 30 will be adorned water.

During material in requiring heating tank 10, jar is inverted and is stood on its top part 14, make the bottom that can touch cover 30.Push a button on the end of bottom as described below, thereby open, make that covering 30 water flows on the quick lime in the reagent chamber 20, causes exothermal reaction at the hydroecium 42 of cover in 30.The steam that produces can by the periphery of cover 30 on the wall in chamber 20 or the hole that on the two, forms or groove (not shown) around cover 30, flow out.The user remains on the position of putting upside down with jar, comes out completely up to steam.In this stage, material is heated to the temperature of a satisfaction in jar.

Fig. 2 illustrates cover 30.In illustrated embodiment, cover is by plastic moulding, and comprises a bottom parts 32 and a lid 34.Bottom parts 32 comprises an almost circular bottom, and the latter has the outer peripheral edges 36 of an annular.This edge limits the groove 38 of an annular, and the latter makes cover 30 can be stuck on the bottom of jar 10.Periphery wall of holding up 40 limits the chamber 42 of a substantially cylindrical of dress water at the radially inner side of outer peripheral edges 36.A round opening of the free end delimit chamber 42 of wall 40 wherein holds lid 34.In the heart, the end 32, have a upright plunger 44 in it.In illustrated embodiment, this plunger 44 has the top of an opening, is used to hold a chuck 46 of lid 34.

Plunger 44 is fixed at the end of center of the button 50 that is limited in the end 32 by circular groove 48.Can see, at state shown in Figure 2, button 50 is protruding, and in circular groove 48 footpaths inwardly.

The chuck 46 of lid 34 comprises the projection 46 of downward extension, and it snaps onto in the top of plunger 44 after chamber 42 is by dress water.Can see, lid 34 also has a upright edge 56 (Fig. 3), and when lid 34 force fits put in place, edge 56 was contained in the opening that is limited by upright wall 40.Lid 34 also is that in edge 56 footpaths inwardly its shape makes any pressure that produces in chamber 42 can push edge 56 and contacts more closely with the inside face of the opening of chamber 42.If necessary, can on the outside of edge 56, form the rib (not shown) of circumferential extension, make their contact the inside face of the opening of chamber 42.Have found that such circumferential ribs prevents capillarity, therefore anti-sealing leaks from chamber 42.

Have found that, when lid 34 has a good force fit in the opening of chamber 42, the leakage of water from cover do not take place in common transportation with when moving.Therefore, when cover 30 was stuck on as shown in Figure 1 the jar 10, it played quick lime is remained in the chamber 20, and water is stayed in the chamber 42, but the effect that separates with quick lime reliably.

When requiring the heating certainly of jar 10, as described above it is put upside down.Press press button 50.The button 50 that is provided with acts on have the center when being pressed above, and button moves to a recessed substantially dome position from its original outstanding dome position.Preferably, button is stable in its two states.The mobile plunger 44 that makes of button 50 moves towards the direction that lid 34 is released the opening of chamber 42.In general, the positive opening of pushing the lid 34 that causes chamber 42 of expectation button 50, thus water flows in the quick lime in chamber 20 apace, and beginning is from the reaction of heating.But, because jars 10 put upside down, so if the pressure of lid does not take place and open fully that also it doesn't matter.At this, as long as lid has some to open, will begin 42 outflow water from the chamber, lid is opened more completely.

The center of lid 34 needn't be fixed on the plunger 44, though this forms a reliable and firm especially structure really.Therefore, plunger can be simply near lid in the off position of Fig. 2.

If embodiment as shown is such, lid 34 remains on bolt on plunger 44, and then the material in the chamber 42 is constrained to periphery 42 outflows from the chamber around lid 34.This makes graphic jar only be fit to and the material adapted that flows, as liquid, powder and other fluid.

Illustrate with graphic jar and can on the interstitial wire of routine, fill, and material wherein can be accepted the processing of any requirement from heating.Then, with jar putting upside down of each complete filling, suitable adding quick lime in exocoel is stuck on the cover of having filled water then.In general, preferably on jar 10, clamp cover 30 simply,, also cover 30 stickups or sealing can be put in place if wish.

Open when beginning reaction with heating tank will covering 30 subsequently, water can 20 be urged out from the chamber towards the edge 36 of cover.Even in this stage,, generally do not require the passage that provides water to leak out though require to have the passage of discharged air and steam.Therefore, fuse, packing ring or semi permeable film (not shown) can be contained in the groove 38 of annular, or are positioned at around the wall 40 of cover 30.In addition and/or alternatively, cover 30 also can be to closely cooperate on jar, and the micro-groove (not shown) can be in circular groove 38 and/or surrounding wall 40.If micro-groove is the magnitude of 6-10 mil, then they make air and steam to discharge, but do not allow water to overflow.

Fig. 4 illustrates another embodiment of cover 30.In the embodiment of Fig. 4, the parts of the cover similar or identical with the parts of Fig. 2 and 3 cover are with identical symbolic representation.

The cover 30 of Fig. 4 is set, makes air and steam discharge by the center.This can be the substituting or replenishing of discharging of above-mentioned periphery.Therefore, in the embodiment of Fig. 4, deflation hole 60 passes the chuck 46 of lid 34.Plunger 44 is a hollow, thus limit one from exocoel 20 to jar the passage of 10 air outside and steam.Preferably, this passage is equipped with filter material 62, anti-sealing outflow when allowing air and discharge of steam.Filter material 62 prevents that also water and other trowel used for plastering things in the atmosphere from entering exocoel 20.

Should be understood that the time because reducing of the volume in cover 30 subsequently normally requires air and discharge of steam by press button 50.Then, must exhaust thereby be heated the result of the chemical reaction that expands as air.Usually being discharged the back at air and steam will continue as the heating of reaction result.

Cover is preferably by the plastics manufacturing.Plastics are preferably opaque at present, make that the water in the cover 30 is invisible.

The outside face of suggestion cover and/or jar 10 is by material manufacture with oxidation tint characteristic or coating.Like this, cause jar from heating if handle cover at any time, then can be by for example obviously observing at the color change of the part of the color change of cover part and/or jars 10.

In one embodiment, the fusing point of the plastics of the lid 34 of cover 30 is enough low, so that the heat that the exothermal reaction of water and quick lime is sent makes its fusing.By this measure, the lime of aquation/expansion can easily be contained in the exocoel 20 of expansion.

Should be understood that in the application's scope and can make modification explanation and illustrated embodiment.
