ABD/OR.IIfli'OSIOII

The  present  invention  relates  to  a  can  for  beverages,  i.e.  a  container  of a

material  suitable  for  food  use  within which •the  beverages  are  sealed  for

preservation and large scale dishi.bution to the final consumer, which, besides

performing said preservation and large scale distribution function for the foods

contained  therein,  enables  sn  extracted  and/ or  iDfused  bevemge  to . be

10    produced at the moment of use by the said can, the thus formed beverage collecting within a cavity in the interior of the can, to be consumed directly

from iL

lt. bas been  statistically. shown, ..that.ooffee .. is .. cme  of the  most  consumed

bevemges in  the world,  a  coffee beverage being that beverage formed  wben

15    ground coffee transfers to hot water the soluble and aromatic substanCes contained therein, both by the effect of extraction when the water heated to a tempeno.ture close to its boiling point is passed through the ground coffee, and by infusion when a certain quantit;y of ground coffee is left for some minutes in
water at 'ltemperature close to its boiling point

20    In public premises such as hotels, cafeterias, refreshment rooms (for example in offices and stations), this beverage is commonly produced by equipment of considerable size, known as 11coffee machines• whi~ require the presence of an

operator.

In private houses this beverage is commODiy prepared using equipment !mown

25    as •coffee pots•, compoSed of relative partsi when required, the consumer fills the appropriate parts with tap water and coffee powder, then assembles the parts, places the combination on a source of heat, awaits the formation of the coffee beverage and pours it into cups, finally separating the pieces of the

combination  and  cleaning them to enable another  beverage  to  be  prepared.

30    Numerous small coffee machine are also available for household use, these reproducing on a small scale the coffee machines of public premises.

For many years the need has been felt by the consumer to be able to obtain the beverage when required, even if he has no coffee pot or large or small coffee

machine available; this happens mostly when the consumer is far from home,

35    for  example  while  travelling,  when  pmctising  sports,  or  when  far  from inhabited centres.

In attempting to satisfy this requirement, powders instantaneously soluble in water have been marketed, such as that known by the trademark "Nescafe•, however the beverage obtained thereby does not satisfy the palate of the consumer to the same extent as that produced by extraction or infusion. In any event, this II!alwohift solution doe not solve the problem of overcoming the
IBck of water, a situation which can occur in particular when the consumer is far from inhabited centres (for example during excursions or in a boat), or even
more  so in countries in which  water is  not ~ available or its  drinking

10    quality is uncertain.

In an attempt to overcome this drawbacl<, cans containing an already prepared coffee beverage have been marketed for same years, the final consumer hea:t:i:ng thexn wben required. However it is well known that the coffee taste alters considerably as a result of subsequent heating after the cooling which the

!S beverage has undergone on preparation, this being shown by the poor distribution Wbich such cans have encountered commercially..
An object of the present invention is therefore to satisfy the aforesaid requirements while at the same time obviating the aforedescr:ibed drawbacke. Another object of the present invention, of primary importance (and of evident

20    usefulness) even if expressed subsequent to the first stated object, is to achieve a mass distribution (similiir to that currently achieved for Coca Cola®) which enables any person wherever located, provided a heat source is available, to enjoy the invigorating and refreshing properties of a true coffee beverage produced at that moment, wbile at the same time preserving those elements

25    necessBJY for preparing the beverage untp. the moment of their use.

A further object is to provide a can which, besides enabling a true coffee beverage to be produced at the m.oment of need, can be .arranged to also produce other beverages obtainable from various substances by extractiOn
and/ or infiltration.

JO    The aforespecified objects are attained according to the present invention by a

beverage can, i.e. a container of the type commonly used for the preservation

and large scale distribution of foods and intended to be disposed of after use,

said can comprising a side wall, a base and a lid, and allowing access to the

foods contained in the can by removing or perforating the lid,

35    characterised in that: immediately below the lid there d. a first chamber not initially containing beverages ready for use, but intended to receive the final bevOrage, said first chamber being separated by a sealed ballle from a second chamber which already contains, when the can is supplied to the user, a suitable quantity of drinkable liquid;

said sealed ballle presenting a housing constructed to sealedly receive the non-permeable portion of a filtering device consisting of an envelope enclosing a suitable quantity of a substance able to produce a beverage by extraction and/or infusion and provided with a tube intended to dip into the second
10    chamber containing the liquid; means being provided to enable the user to dispose the filtering device in the utilization condition in which communication is established between the two chambers via the filtering device such that, when the can is subjected to the action  of  a  heat  source  by  the  user,  the  liquid  contained  in  the  second

IS    chamber, on attaining a temperature close to boiling point, is tranaferred into the first chamber by passing through the substance contained in the filtering

device, to give rise to the formation of the beverage.

The filtering device is preferably already contained in the first chamber, even if not located in i1B position nf utilization, it then being brought into the

20    utilization position by the user.

Different types of beverages formable by extraction or infusion can be obtained in the same. manner using various substances such as ground coffee and

barley, tea, cocoa; said substances can be ground to a more or less fine degree

which can vary from very line powders to pieces of chopped leaves and can be

25    mixed with other foods, for example powdered milk, sugar; hereinafter the term "beverage• will always be used for the final liquid product and •substance• for that contained in the filtering device and able to give rise to the beverage. In the same manner the drinkable liquid will most commonly be water, but can

be replaced by or enriched with other liquids such as milk, to give rise to the

30    formation of beverages other than coffee, such as cappuccino; the final liquid product will in all cases be known as the "beverage".

According  to  one  embodiment  of the  present invention,  the  first  chamber,

intended to receive the final beverage, forms one piece with the hollow chamber

containing the liquid.

35    1\ccording to  a  variant of the invention,  the first  chamber for  collecting the beverage and the second Chamber clmtaining the liqtrld form one piece with each other and with a sealed bafile which separates them.

According to another variant of the invention, the first collection chamber is bounded by a container of roughly cup shape with its mouth facing upwards and having a shape and dimensions such as to be able to be inserted within

the side wall of the can to form, between said container and said side wall, an

interspace within which wben the can is supplied to the user there is already interposed a determined quantit;y of liqtrld; the container and the side wall of the can having at least one perlmeln!l region in contact and being sealedly

LO joined together at least in this region. It should be noted that in the described exmnple those walls of the cup-shsped contalner acljacent to the interspace act
•    aa a separation baftle, the inter>opllee forming the second chamber.

According to  one  embodiment of the invention,  the  can  is  provided  with  a

filtering device to be inserted into a housing disposed for this purpose on the

13    separation baftle, said housing being initially closed by an impermeable membrane. Said filtering device can be sealedly inserted by the \' - into the housing auch aa to break the membrane and hence be in its working condition. The filtering device consists of an envelope Which is closed or is closable in the manner of a capsule intended to retain the substance, one end of said envelope

20    being provided with a tube intended to dip into the interior of the second chamber containing the liquid, the other end of said envelope p,..,..,ting at leaat one filtering region, i.e. permeable only to liquids so that the liqwd, having passed through the ground substance, can emerge into the first chamber acting as the collection chamber; at least one portion of the non-

23    permeable region of the filtering device is shaped to insertingly mate with the housing disposed on said separation baftle, and vice versa.

If necessary, the stsbilit;y and the seal of the filtering device at the perimeter of the housing in which said device has been inserted can be ensured by suitable

gaskets.

30    Conveniently, when the can is supplied to the user, the filtering device is already contained in the fli'st collection chamber_ so that the user, having removed or perforated the lid, has access to said filtering device and can

operate on it to move it into its final working position. Alternatively, the filtering device could be not already located in the can, but instead accompany

35    it, for example in a package containing a can with a filtering device next to it.
 


s

Conveniently the filtering device already contains a detemrined quantity of substance when the can is supplied 1D the user. Alternatively, said quantity of substance could be not contained in the !i1tering coffee but instead could accompany it (for example Suitably packaged within the collection chamber), in which case the filtering device must be openable to enable the user to insert said substance into it. In particular the substance can be packaged within a permeable envelope (for example a sachet of filter paper) insertable into the filtering device.

According  to  one  embodiment  of the  invention,  the means  for  putting  the

10    substance contained in the filtering device into communication at the moment of use with the interior of the mass of liquid contained in the second chamber
comprise:

a tube forming part of the illtering device, one end of the tube being free;

a region of the sealed separati011 ballle piereeablo by the free end of the tube

IS    by the intervention of the user;

and means for prcwiding the outward seal between the second chamber already containing the liquid and ihe tube when the can is in its utilization condition.

According  1D  a  fwther variant of the :invention,  the means for  putting the

20    substance contained in the filtering device into communication at the moment of use with the interior of the mass of liquid contained in the second chamber comprise:

a  housing  disposed  on  the  sealed  separation  ba11le  end consisting  of a

circumsCribed region which can be opened by the user by lifting a  tab or by

2.1    piercing, such as to create a through hole between the second chamber already oontaining the liquid aod the 6rst chamber intended 1D contain the final beVeTBge, within which bole the filtering device can be receivedj

and ineans for• providing the outward seal between the second chamber already containing the liquid and that portion of the tiltermg device which has

30    been placed in the hole by the user.

The invention will be more easily understood from the ensuing description of two embodiments thereof given by way of ex8Illple. In this description,
reference is made to the accompanying drawings, in which:

Figure 1 is a vertical axial section through a frrst embodiment of the can of the

35    invention, this can being in the condition in which it is supplied to the user;
 



Figure 2 is a section sintilar to thf.t of figure I, but with the can in its utilimtion condition achi"""d by the intezvention of the user;
Figure 3 is a partial section through a variant of the can of Figures 1 and 2, in the condition corresponding to that of Figure I;

Figure 4 shows the same variant as Figure 3, but in the condition corresponding to Figure 2;

Figure 5 shows a detail of anotller variant of the can of Figures I and 2; and

Figure 6 shows a detail of another variant.

As can be seen in Figures 1 aod 2, the can 10 -indicated specifically by 1 OA in

10 the condition of Figure I and by JOB in the condition of Figure 2 - comprises an outer container 12 of cup shape and an inner container 14 also rougbly of cup shape, the inner contsiner 14 being inserted concentrically into the outer container 12. In the illustrated example, the two cups 12 and 14 are of a suitable material (for example aluminium or plastic) to enable the relative
ll upper edges to be turned over and clinched or welded together in conventional manner (as shown schematically in said figures), to obtain a seal between the two. Consequently a sealed interulediate chamber 16 is obtained, already containing a quaotity of liquid (for example water). The inner container 14, the walls of which also act in this case as the separation bafile, laterally and

20 lowerly bounds an upperly open chamber 38 to act as the chamber for receiving the beverage produced in the can 10. As can be seen in Figure 1, an upperly open coaxial duct 20 extends downwards from the base of the inner container 14 and is closed lowerly by a sealing membrane (for example a sheet of aluminium of the type which closes the mouth of certain toothpaste tubes).

ll    As can be seen from Figure 1, a tube 22 of a suitable material, for example plastic, and forming part of a filtering device indicated overall by 24, is partially inserted by slight forcing into the duct 20. The tube 22 bas ao outer diameter such that to insert the tube 22 into the duct 20 a force has to be

exerted  which  besides  serving  to  retain  the  tube  22  in the  duct  20  (the

30    condition shown in Figure 1), also• provides the required seal between the tube

22 and the duct 20. Consequently, by forcing the tube 22 of Figure I downwards into the duct 20, the user obta:ins the situation shown in Figure 2 in which the lower end (preferably shaped as a flute mouthpiece, as in said figures) of the tube 22 has pierced the sealing membrane 34 which closes the

35    lower end of the duct 20.  in addition to the tube 22, the filtering device 24
 



also comprises a hollow part shaped 1.s a capsule 26 (substantially spherical in the specific example) ~dy containing a determined quantity of substance 28

(for example ground coffee). The substance 28, which can also be in the form of granules or powder, cannot descend into the tube 22 because at its upper mouth, communicating. with the interior of the spherical wsll 26, there is provided a liquid-permeable bafile, indicated in Figure 1 by 30 (for example formed from IDter paper or a auitable mesh). As can be seen in Figure 1, the spherical part 26 of the IDtering device 24 presents a series of perforations 32 in its upper part so that the capsule is provided with a permeable region

10    through which the final b""""'&" can emerge.

When the can 10 is supplied to the user (i.e. when he purchases it), the filtering device 24 is in the condition lOA of Figure 1, as stated.

It should be noted that the can 10 could remain in the condition lOA of Figure 1 even during use if the sealing bafile 34 is formed of a substance able to

IS dissolve following hesfu,g. In that case the intetvention of the user is limited to the operation of subjecting the can lOA to the action of a source of heat. The same would apply if the sealing bafile consisted of a membrane pierceable by the effect of the pressure incresse created within the second chamber containing the liquid 38 when the can is subjected to the action of a heat

20    source; this membrane would evidently have a resistance to pressure less than that of the wsll 16 of the chamber 38 and of the separation bafile 14, and also less than that of the release pressure of the safet;y valve with which the can is provided (and which will be descn'bed hereinafter). Again in this case the intervention of the user is limited to the operation of subjecting the can lOA to
25    the action of a heat source.

The can lOA is conveniently provided with a removable lid 40; the edge of this lid can be turned over and joined by clinching or welding to the edges of the two containers 12 and 14, the lid being for example provided with a known
ring (not shown) for tearing off tlie lid.  Alternatively, the can could be provided

30    with a common cover (for example of plastic) 42 applicable by pressure to the upper edge of the can 10. The can could also be provided with a further cover positioned !for example for hygienic reasons) above one of those already

described.

AB  will  be  apparent from  the  aforegoing description,  the  can is of extreme

35    simplicity and very low cost (especislly if constructed  of aluminium  and/ or
 



plastic).  This is important given that~ as will be imniediately apparent, the can

cannot be reused in practice, so that it is of disposable type, to be thrown away

after use.

It  should  be  noted  that  the  tenn  •can"  is  commonly  used  to  define  food

containers constructed of materials other than the tinplate formally used for

the  originally  named  "tin cans", . provided  that  they  are  suitable  for  food

preservation, for example aluminium or plastic, hence in the present invention

the can construction material is to be understood in the widest sense.  For the

same  reason  the .. teJm. ~can~. also  -indicates. containers .of. not. exclusively

10    cylindrical shape (for example parallelepiped).

Although apparent from the aforegoing description, a short description will now be given of the use of the can 10 for greater clarity.

As stated, the user purchases the can  10 in the condition  lOA of Figure  1.

When  he  decides  to  use  it  to  obtain  the  relative  beverage,  the  user  after

IS    removing any cover bas merely to force the filtering device 24 inwards with the fingers so that the tube 22, wbicb bas not yet been completely inserted into the duct 20, enters it as far as possible. The result is that the flute mouthed tip of the tube 22 pierces the seOting ba111e 34, until it arrives in proximity to the base of the outer container 12 (the can being now in the condition lOB of

20    Figure 2) so that the tube 22 dips into the mass of liquid (for example water) contained in the second chamber 16. The filtering device 24 is advantageously constructed of a plastic material suitable for contact with foods but sulliciently rigid to enable the tube 22 to be forced into the duct 20, the forcing also ensuring the necesaary seal between the tube 22 and the inner wall of the duct

2.l    20.

With the-• can in-the condition• lOB •R need- only-be subjected• to-the- action-of a  •

heat source (for example by placing it on a flame or in a microwave oven). Wltil

the liquid 18 contained in the chamber 16 boils, so that this liquid rises along

the  tube  22,  passes  through the mass of substance 28   contained  in the

30    capsule 26, to leave in the form of a beverage from the perforations 32, and be finally collected in the inner container 14 which, as stated, acts as a collection chamber for the beverage; at this Point the user can also drink the beverage directly from the can, as happens with other beverages (for example beer) commonly distributed in cans. When the beverage has been drunk or used,

35    the can is disposed of.
 



It should also be noted that the can91fi can also be sold without the filtering device bein& located in the position of Figure 1, it simply lying in the inner container 14 if sufliciently large. In that case a closure, for example a cover of the aforedescribed cypes, prevents the accidental escape of the filterin& device

from the can upper ap~re while at the same time preserving its aroma.  As

an alternative to the aforedescribed covers, but for the same covering purpose,

the can could be wrapped in a packaging wrappin&, for example in a sheet of beat-shrinkable plastic). It should be noted thai the filterin& device can also be disposed on the outside of any cover. If the filterin& device 24 is not already

10    disposed in the position of Figure 1, breakage of the separation baffle 34 can take place in a pierceable region 34, which can be pierced by other means instead of the lower end of the tube 22, and in particular by a plastic stick or pin with which the can may be provided. Another variant is that shown in

Figure  5,  in  which  the  duct  220  extends  slightly  shove  (portion  220A)  a

15    separation baffle 214, on the upper mouth of the portion 220A there bein& applied a sealing membrane 234 which can be torn off by the user on utilization, this operation bein& facilitated by a grippin& tab 235.

Accordin&  to  a  particularzy  simple  variant  (Figure  6)  of the  invention,  the

bousin& for the tube 22 and the pierceable region of the separation baffle are

20    obtained simply by centrally providing in the separation baffle 314 a thin circular ar.:a 334 which is easily pierced by the tube 22 or by other means.
Accordin& to a further variant of the can of the invention (shown partially in Figures 3 and 4, but for the rest similar to that of Figures 1 and 2), the larger diameter upper part of the tube 122 is externally threaded, this thread bein&

25    arranged to engage a female thread provided in the inner wall of the duct 120. In Figure 3 the filtering device 124 (which in this case is of ovoidal shape) is in the condition (that in which the can is supplied to the user) in which only a

part of the  threaded portion of the tube  122 is  screwed  (preferably  slightly

forced) into the duct 120.

30    When the user wishes to use this can, he merely screws the tube 122 completely into the duct 120, with the result that the lower flute mouthpiece-shaped end of the tube 122 pierces the sealing membrane 134, to achieve the condition shown in Figure 4, in which the lower end of the tube 122 dips into the liquid contained in the second chamber (not shown). This embodiment is
35    appropriate both if the filterin& device is formed of a suitable plastic materisl,
 



so that by appropriately choosing thtl'lumensions and material of the tube 122 the seal can also be obtained between the tube 122 and the duct 120, and if a suitable metal (such as aluminium) is used or a plastic material which does not enable ssid.seal.to.be.obtamed.. Howeoer.in-this.latter.case.a seal-gasket ouch as that indicated by 14() in Figures 3 and 4 must be used to provide the
seal

1t should be noted .that if in addition to the filtering device 24 or 124 the two containers 12 and 14 are also constructed of an appropriate plastic suitable
for contact with food, the can will not be suitable for placing on a flame or an

10    electric hotplate, but can be used by hlsertion into a microwave oven.

F:ina1J,y it should be noted that the can of the invention, and particularly the second chamber already containing the liquid, can be conveniently provided
••with-a-ssfety•Yalve.- This latter can be conveoiently positiot~ed-lo-ven!•into •the••••• first chamber acting as the collection chamber. In this manner external
IS projections are avoided so that the can does not differ externally in its shape and appearance from a normal commercially available food can and can be treated and haDdled as such.

With regard to the substance to be used in the can of the invention to obtain the relative beverage, in addition to chopped or powdered substances,

20    substances of gelatinous form (including in capsules) can be used, provided they are suitable for producing the required beverage when located in the filtering device.
