Description
The present invention relates to the jar of two carrying liquids or charge of flowable solids or the container of sealing chamber, be used as such as soft drink or beer can.
Existing soft drink or beer can comprise a cylindrical sheetmetal tank body substantially, have a discoid sheetmetal cover that closely is fixed in its top edge.The sheet metal technology process that this existing tank body adopts the skilled person in present technique field to know is made with callable aluminium or sheet steel.
Existing soft drink or beer can only can a kind of liquid of splendid attire.But the past had proposed to improve this tank body by the interior jar that wraps into second kind of liquid of a splendid attire.
Authorize the example that the US Patent of Hitzler is described a this multichamber vessel the 4th, 919, No. 295.Hitzler has adopted cylindrical outer jar of a kind of oldfashioned.And the tank body that uses at present is to adopt smooth necking down technology to form a tapered shaped can neck at the opening part that is positioned at cylindrical blank top.The intensity of this new-type necking down technology is beneficial to saving in material, the intensity that strengthens anti-vertical stacking unstability and the space that reduces to store in a warehouse etc.
The interior jar of Hitzler comprises that one abuts against the semicircle uniform cross section tank body on half inwall of cylindrical outer jar.The cover of Hitzler partly is made up of two semicircle sheets that link together at its straight line.The vertical linear edge of jar in two straight lines are connected in its base, thus a center-line joint that traverses the top surface of the circular cover that connects into formed.
The shortcoming of the described multichamber vessel of Hitzler is: its two-piece type cover parts are relatively complicated and in fact be difficult to make.Cover is made up of two parts, and they must link together at the centerline and the interior jar of cover.In most cases, the liquid of splendid attire in this tank body is under the pressure, and therefore, the sealing reliability between tank body and its extraneous air is of crucial importance.Especially true when each of container is indoor at the numerous food splendid attire.
Another shortcoming of the multichamber vessel of Hitzler is that the liquid capacity outside the volume ratio of jar interior liquid can be contained in being contained in the remainder of jar is few.Because cover is along its center linear sealing, the liquid capacity of splendid attire in half-cylindrical jar because of interior jar wall thickness be less than outside half of jar internal capacity.
Shortcoming that can not the splendid attire same capability is: the marketable value that has limited multichamber vessel.For example, three multichamber vessels can be used to replace volumetric standards jars such as six.And the interior liquid of container mixes as certain purposes to wait capacity if desired, such as epoxy resin and epoxy settable compound are mixed, just can not adopt the unequal multicell jar of this each chamber volume.
Multichamber vessel can be used as a kind of sales aid and waits capacity ground to sell two kinds of products of a company.Such as, a tame beer company may wish a kind of lager and a kind of brown stout together are contained in the multichamber vessel as a kind of sales promotion instrument.Can not wait capacity to sell and to increase Consideration and trade mark demand in the production at two of multichamber vessel indoor liquid products.Its result has reduced the attractive force that originally can be used as a kind of multichamber vessel of marketing tool.
Therefore need to produce a kind of multichamber vessel that can not only simply easily make and can between a plurality of chambers and extraneous air, reach positiver sealing with minimum parts.
Also need to produce the multichamber vessel that a kind of volume of wherein each compartment all equates.
For guaranteeing that any multichamber vessel is accepted by market, adopt newfangled outer jar profile to have actual essentiality.Outer jar should adopt existing machine to be shaped in large quantity and print, and the improvement that any requirement changes received manufacture method all may cause the coml failure.Therefore, the volume that needs to make a kind of wherein each compartment all equates, and its outer jar of multichamber vessel with up-to-date universal standard profile.
The present invention is in order to overcome above-mentioned the deficiencies in the prior art, proposed to make a kind of method of a kind of novelty of multichamber vessel, and it comprises: one outside its open top end periphery has the hollow of a top edge jar; One has in the hollow on a top margin edge jar along its open top end periphery, and interior jar is placed in outer jar, stacked with the adjacent portions phase-splitting of the first on its top margin edge and top edge; The second portion on top margin edge traverses outer jar described open top end; One cover, it seals outer jar and interior jar of both described open top ends, thereby in interior jar, form one first sealing chamber, and in outer jar of interior jar of outside, form one second sealing chamber, cover has a circumferential slot and horizontal interest that a downward turnup forms and the inside groove under shed that is communicated in described circumferential slot along its outer peripheral edges, the circumferential slot of cover clamps superimposed the first on the top margin edge of outer jar top edge and interior jar hermetically, inside groove then clamps the second portion on top margin edge hermetically, and the second portion on inside groove and described top margin edge forms a superimposed seam that is folded on the cover end face.
The present invention also provides a kind of manufacturing method of the multichamber vessel of can, and it comprises:
First kind of liquid poured into along the open top end periphery to be had in the hollow on a top margin edge jar, roughly irritates to the liquid level that is lower than described top margin edge, and this top margin is along being made up of along part first and second top margins;
With the described interior jar open top end of cover sealing, thereby in interior jar, form one first sealing chamber, cover along its outer peripheral edges have circumferential slot that a downward turnup forms and one across and be communicated in the described circumferential slot inside groove that Open Side Down, the inside groove of cover embeds for the second portion on top margin edge, and at least a portion of circumferential slot is for first's embedding on top margin edge;
Closely the second portion of inside groove with the top margin edge is clamped to;
Put down on the end face of cover the second portion on inside groove and top margin edge is folded, thereby form a superimposed seam, its two ends and described circumferential slot tandem;
Second kind of liquid is partly poured into the outer jar of a hollow, and this outer jar has a top edge along its open top end periphery;

Fig. 1 shows the general layout that the multi cavity container of jar 2 in outer jar 1 and one hollow of a kind of sky is arranged of the present invention.One disc cover 3 is sealing both tops of outer jar 1 and interior jar 2, thereby forms first and second sealing chambers 4 and 5.As shown in Figure 2, first sealing chamber 4 is to be formed in interior jar 2, and second sealing chamber 5 is in the outer jar 1 of jar 2 outsides in being formed at.
As shown in Figure 1, cover 3 preferably one have one it is divided into the disk of the superimposed seam 10 of two semi-circular portions symmetrically.Each semi-circular portions has its independently tin opener 6, and it can adopt jar form of opening of any existing drinking container.
The part sectional view of Fig. 8 and the birds-eye view of Fig. 9 show the features of novelty of cover 3 and the hermetically-sealed construction of first, second sealing chamber.Outer jar 1 is hollow, and along its initial openings top periphery one top edge 7 is arranged.
Fig. 8 and Fig. 9 show the final structure shape of cover 3, and Fig. 3 to Fig. 7 shows the progressively forming process of periphery crimping 21 and central superimposed seam 10.
As shown in Figure 8, outer jar 1 has a top edge 7 along its initial openings top periphery.Interior jars 2 of hollow has a top margin along 8 along its initial openings top periphery.As shown in Figure 3, cover 3 circumferential slot 12 that has a downward turnup to form along the outer peripheral edges of its disc cover.Cover 3 also has an inside groove 13 under shed, and it crosses and communicates with circumferential slot 12.
Obviously, the can of two chambers of this container and the manufacture method of this container link together inseparably, and the method that is used to make a multichamber vessel of the present invention is described below.
As shown in Figure 3, interior jars 2 of hollow has a top margin along 8 along its open top end periphery, this top margin along 8 have one substantially the firsts 20 and of semicircular in shape be roughly straight second portion 9.Show that as Figure 13 is detailed second portion 9 is than the one section size S in 20 ends of first.As shown in Figure 3, top margin is initial along 8 upper end to form one to the antelabium 22 that turns up, and its width is approximately S.Antelabium 22 is used to guide cover 3 when cover 3 is installed, and when this jar is made fully, is folded into outer peripheral edges crimping 21.
First kind of liquid 23 can of interior jar of 2 usefulness of hollow are roughly to being lower than the liquid level of top margin along 8.
Then, cover interior jar 2 open top end with cover 3, as shown in Figure 3.Thereby, form one first sealing chamber 4 in the jar 2 in cover 3 makes.The circumferential slot 12 that cover 3 has a downward turnup to form along its outer peripheral edges 24, cover 3 also has an inside groove 13 under shed, supplies the straight second portion 9 on interior jar 2 top margin edge to embed wherein.Shown in this embodiment in, the first 20 on top margin edge roughly is inserted into half of circumferential slot 12.On the composition surface of cover 3, be coated with leakproofing material to improve antiseep.
With the same usually, first kind of liquid 23 contains cmpd, and it can the generation carbon dioxide make the liquid carbonization after after a while.This chemical reaction carries out in a period of time lentamente.Therefore, when at first being filled for interior jar 2, first kind of liquid 23 can not produce tangible pressure to cover 3.After the leak free multichamber vessel was made fully, the liquid 23,26 that carbonization process is proceeded in described chamber 4,5 was pressurizeed fully.
In the time of on covered by can when cover 3 interior jar 2, use such as rolling wheel etc. inside groove 13 and the top margin second portion 9 along 8 is closely clamped.
As shown in Figure 4 and Figure 5, next step is straight second portion 9 folded the putting down on the end face 11 of cover 3 with inside groove 13 and top margin edge, thereby forms a superimposed seam 10, its two ends 25 and circumferential slot 12 tandem mutually.In an illustrated embodiment, superimposed seam 10 is once folded putting down on the end face 11 of cover 3.Obviously, if desired, superimposed seam 10 can carry out twice superimposed.Superimposed seam 10 is divided equally the end face 11 of cover 3 symmetrically, and this mainly is for visual effect.Cover 3 is one to be divided into the disk of two semi-circular portions by superimposed seam 10 substantially.As shown in Figure 4 and Figure 5, for beautifying visual effect, make the split of cover 3 and outer jar 1 show online X-X place, therefore, the superimposed seam 10 that is in final folded mean place is a line of centers with line X-X.
Next procedure in the Fabrication procedure is outer jar 1 with second kind of liquid 26 partly can hollow.Along its open top end periphery one top edge 7 is arranged for outer jar 1.As shown in Figure 6, top edge 7 has a upwards outer tapered lip 27 of opening, and it is used for guiding cover 3.
Then, insert in outer jar 1 interior jars 2, jars 2 lower submerged and makes that the liquid level of first kind of liquid 23 and second kind of liquid 26 is preferably roughly the same as shown in Figure 6 when interior jar 2 last location in the name in second kind of liquid 26.Top margin is stacked with the adjacent portions phase-splitting of top edge 7 along 8 first 20, shown in the right part of Fig. 6.Shown in the middle part of Fig. 6, jar 1 open top end outside the second portion 9 of top margin along 8 traverses.
Therefore, as shown in Figure 6, cover 3 has sealed outer jar 1 and interior jar 2 both open top end, thereby forms one first sealing chamber 4 in interior jar 2, and forms one second sealing chamber 5 in outer jar 1 of interior jar of 2 outsides.The circumferential slot 12 that the downward turnup of cover 3 forms is positioned at outer peripheral edges 24 places of cover 3, is used for embedding whole top edge 7 of outer jar 1, the semicircle superimposed part 20 of jars 2 top margin along 8 in also being used for embedding.The inside groove 13 under shed of cover 3 traverses and communicates with circumferential slot 12 so that cover 3 can be buckled in jars 2 and outer jar 1 both open top end on.
After cover 3 location, as shown in Figure 6, outer jar 1 open top end is just sealed by cover 3, therefore, forms second sealing chamber 5 that second kind of liquid 26 is housed in outer jar 1 of interior jar of 2 outsides.Carburizing reagent to take place with the roughly the same mode of above-mentioned first kind of liquid in second kind of liquid 26 in a period of time.
The next procedure of manufacturing process is that the circumferential slot of cover 3 is closely clamped outer jar 1 top edge 7 and interior jar of 2 top margin superimposed the first 20 along 8.Fig. 6 to Fig. 7 shows the situation of going forward one by one of seal process, and Fig. 8 shows the final position.
Comparison diagram 6 and Fig. 7 as seen, the step that closely tightens up circumferential slot 12 preferably includes turnover circumferential slot 12 twice.At first, resemble as shown in Figure 7 with circumferential slot inwards backfin to encase top edge 7 and top margin superimposed the first 20 along 8.With the same usually, be applied to the sealing surfaces of circumferential slot 12 with chemical sealant or liquid rubber.
To the process of going forward one by one shown in Figure 8, circumferential slot 12 has been turned down once again with the top edge 7 that is encased by it and top margin superimposed the first 20 along 8, has formed periphery crimping 21 at Fig. 7.
The final condition of the intermediary of the cover 3 in the comparison diagram 5 and cover 3 shown in Figure 9, as can be seen, the next step that will carry out is the two ends 25 of the superimposed seam 10 of repoussage, and the inside face 27 that makes superimposed seam 10 and periphery crimping 21 is in the same place with rectangular bight tandem roughly.Levelling process can carry out with the pressing mold that clamps surface outside the periphery crimping 21.
Top margin is pressed from both sides to fold in circumferential slot 12 and inside groove 13 along 8 provides further failure-free sealing for the liquid that is contained in first sealing chamber 4.
Features of novelty of the present invention is that first Room 4 and second Room 5 have identical substantially volume.Thereby improved the possibility of the business development of multichamber vessel.
The detailed structure of jar 2 in Figure 10 to Figure 13 shows.Interior jar 2 conventional approachs that at first adopt person skilled in the art to know are made for a cylindrical tank.Be initially the cylindrical tank that one first outside radius is represented with size r for interior jar 2.In jars 2 can adopt at first the method known altogether with the aluminium of recyclable utilization or steel become a cylinder-shaped top opening jar.Then, the final shaping at interior jar 2 tops can be by carrying out repoussage to cylindrical blank and deburring is finished in shaping dies.
In jars 2 an outer bottom 15 is arranged, interior canned go into outer jar 1 in the time, as shown in Figure 2, the inner bottom surface 16 of jar 1 outside this outer bottom is resisted against.Also comprise for outer jar 1 being roughly columniform cover, its second inside radius R is greater than the first outside radius r of interior jar 2.
In jars 2 top margin be configured as substantially a semicircle along 8, its outside radius equals second radius R.In jars 2 top a transitional surface 17 is arranged being roughly between the cylindrical part 18 that semi-round top margin is first radius r along 8 and one bottom radius, transitional surface 17 comprises an acclivitous plane surface 19, and this plane surface ends at the straight flat second portion 9 of top margin along 8.In an illustrated embodiment, because final superimposed crimping is different with the height of central superimposed seam 10, second portion 9 need be made for and be lower than top margin along size S of 8 remainders.
In an illustrated embodiment, outer jar be shaped as conventional shape in soft drink or the beer can industry, it is one columniform jar substantially, its bottom radius is greater than second radius R, and has a level and smooth conical neck 23 that bottom and top edge 7 are coupled together.
For guaranteeing that the superimposed partial sum top edge 7 of top margin along 8 engages with close relation, the inside radius of top edge 7 and top margin all are substantially equal to second radius R along 8 outside radius.
Equally, because of interior jar 2 is to be made for the cylindrical tank that an outside radius is r at first, the best relation between one first radius r and second radius R is arranged in the optimum dimension of jar 2 in determining obviously.Because the shaping at the top of semicircular in shape is preferably undertaken by bending and interior jar 2 material is too extended substantially.Therefore, top margin should be approximately equal to the girth of bottom 18 along 8 girth.
Consult Figure 14, the best relation between first and second radiuses can be described below with mathematical way:
The top perimeter of interior jar 2 bottom circumference≤interior jar 2
2πr≤πθR/180+2R·Sin（θ/2）
r≤R（θ/360+Sin（θ/2）/π）
168 °≤θ≤179 ° wherein
So, 0.78317R≤r≤0.81524R
Obviously, be line of centers if superimposed seam 10 is axis X-X with cover, θ will be always less than 180 ° so.If do not need a kind of like this FINAL APPEARANCE, perhaps, do not equate that θ can select other scope so if require the volume of first Room 4 and second Room 5.
Though the several optimum examples that can be applicable to soft drink or beer can of the present invention has been described and illustrated to the disclosure,, should be appreciated that the present invention is not limited to these certain embodiments.But, the present invention includes all on function and structure with described herein and graphic certain embodiments and feature class with whole embodiment.
