Description

DESCRIPTION
FILTER-BAG FOR INFUSION PRODUCTS AND METHOD FOR
MAKING FILTER-BAG
Technical field
This invention relates to a filter-bag for infusion products and a method for making the filter-bag.
More specifically, the invention relates to a filter-bag for liquid infusion products, in particular hot liquids (such as, for example tea or chamomile), in powder, granules or leaves.
Background art
There are currently two different types of filter-bag on the market: the so- called "traditional" filter-bag, which, in effect, has a substantially flat final configuration, and the filter-bags with different three-dimensional shapes, such as, for example, tetrahedral or spherical (when the filter-bag is obtained by thermoforming process).
The first type of filter-bags is obtained starting from one or more pieces of filter material which are suitably folded and joined to make one or more chambers, each containing a dose of product intended for infusion in liquid (water).
The filter-bag thus formed may be combined with a string which is joined at one end to the filter-bag and at the other end to a tag, used to handle the filter-bag during infusion.
This type of filter-bag is, advantageously, extremely practical because it is relatively easy to make in current machines and it also quick and easy to package.
On the contrary, their shape (substantially flat) makes filter-bags of this kind unsuitable for containing infusion products of different, coarse-sized kinds, such as granules and leaves, which need a different containment chamber, that is to say, a larger chamber with more space for infusion to allow the passage of a larger amount of liquid and thus to obtain a better quality infusion.
The three-dimensional configuration makes these filter-bags not only attractive but also functional because they are easy to handle for infusion and have a large chamber where the product can come into contact with the liquid.
However, neither of the types of filter-bags described can, currently, satisfy all the needs which the current market lines and the specifications of the end user require.
More specifically, for many international markets one of the requirements is that of being able to use a base product (for example, tea or camomile) combined, preferably only during infusion, with a flavoured product.
The current filter-bags are not designed and/or structured in such a way as to combine two separate products in a single filter-bag (except by means of a mixture of products prepared before packaging).
In addition, the filter-bags obtained by the thermoforming process do not allow a clear vision of the product contained therein (due to the intrinsic features of the structure of the material subjected to the thermoforming which make it, at the end of its process, substantially opaque) thereby possibly lowering the appearance quality of the filter-bag.
Disclosure of the invention
The aim of this invention is to provide a filter-bag for infusion products which is able to overcome the drawbacks described.
A further aim of this invention is to provide a filter-bag which is able to give a direct vision of the product(s) contained and with a very attractive appearance.
A further aim of this invention is to provide a filter-bag which is able to contain several infusion products in a reduced space whilst maintaining the qualitative integrity of each individual product until the infusion.
A further aim is to provide a method for making the filter-bag for liquid infusion products.
These aims are fully achieved by the filter-bag for infusion products and by the method for forming the filter-bag according to this invention and as characterised in the appended claims.
More specifically, the filter-bag for liquid infusion products according to the invention comprises a thermoformed body with filtration properties having an inner volume defined by a bottom, a mouth, or opening, delimited on the perimeter by an upper flat edge and a connecting wall between the bottom and the upper edge.
Also according to the invention, the wall is provided with at least one rib extending from the bottom towards the upper edge in such a way as to define at least two chambers for containing corresponding infusion products separate from each other and included in the internal volume of the thermoformed body.
Also according to the invention, the filter-bag comprises a flat piece of non- thermoformable filter material, having transparency characteristics, and associated with the upper edge of the thermoformed body for covering the opening and separating the chambers obtained in this way.
Advantageously, the non-thermoformable filter material, for providing transparency characteristics, is of the "woven" or "non-woven" type.
Also, advantageously, the non-thermoformable filter material, for providing transparency characteristics, has air permeability values (UNI EN ISO 9237) greater than 1000 cm3/cm2»s.
Preferably, the non-thermoformable filter material has air permeability values between 1000 and 10000 cm3/cm2»s, more preferably between
3000 and 7000 cm3/cm2»s.
Thanks to a filter-bag structured in this way, it is possible to achieve particularly satisfactory results both for infusing the product (thanks to the three-dimensional volume of the thermoformed body) and with regards to the attractive appearance.
The structure of the filter-bag according to this invention makes it possible to obtain, advantageously, in a single component, the presence of two different infusion products (for example a main product and a flavouring product) separate from each other until the liquid infusion of the filter-bag. The presence of the non-thermoformable transparent piece for closing the thermoformed body allows a clear and immediate vision of the type of products contained.
Preferably, the separating rib extends towards the upper edge to form at least one further inner wall in such a way as to interrupt the continuity of the bottom.
In light of this, the rib has an extension, calculated starting from the bottom, such as to allow at its upper end to come into contact with the piece of transparent filter material for closing the opening.
This characteristic ensures a complete separation of the inner chambers as well as an increase in the mechanical shape seal of the filter-bag.

Also according to the invention, the filter-bag 100 comprises a flat piece 8 of non-thermoformable filter material, having transparency characteristics, and associated with the upper edge 3 of the body 1 for covering the opening and separating the chambers 6, 7 obtained in this way. Advantageously, the filter material is of the "woven" type.
Alternatively, the filter material is of the "non-woven" type.
The non-thermoformable filter material having transparency characteristics makes it possible to see the product contained inside the bag.
It should be noted that, preferably, the above-mentioned two infusion products P1 and P2 may be, respectively, a so-called basic product (tea or chamomile) and a flavouring product (for example, fruit and/or plant-based flavours).
Preferably, the rib 5 extends towards the upper edge 3 to form at least one further inner wall 5a in such a way as to interrupt the continuity of the bottom 2 (see Figures 1 to 17).
In other words, the rib 5 extends from the base 2 and modifies the extension of the wall 4 generating one or more walls inside the original volume of the body 1 , thus separating both the bottom 2 and the wall 4.
Preferably, the rib 5 has an extension, calculated starting from the bottom
2, such as to allow its upper end 9 to come into contact with the piece 8 of transparent filter material for closing the opening.
In light of this, the rib 5 has its upper end 9 substantially coplanar with the upper edge 3 of the body 1.
In a first embodiment of the filter-bag 100 (Figures 1 to 6), the upper edge 3 is circular in shape and the rib 5 is configured to obtain a diametric separation of the body 1 in such a way as to define two chambers 6 and 7 of similar volume through the formation of a bottom 2 with a twin lobed shape.
In light of this, the rib 5 has a rectilinear extension of its upper end 9 in such a way as to form two separate parallel inner walls starting from the bottom 2 and projecting towards the upper edge 3.
It should be noted that to obtain this shape, the rib 5 consists of two walls spaced from each other by a distance D (see Figure 3) which is then the width of the upper end 9 of the rib 5.
In a second solution of the filter-bag 100, illustrated in Figures 7 to 12, the upper edge 3 is circular in shape and the rib 5 has an undulating extension of its upper end 9 in such a way as to define two separate walls with an undulating extension parallel to each other starting from the bottom 2 and projecting towards the upper edge 3.
It should be noted that the extension of the rib 5 is in the shape of an "S" and allows the two chambers 6 and 7 to have a substantially identical volume.
In light of this, the bottom 2 and the wall 4 are interrupted by the two walls with an undulating extension which define an S-shaped channel along the bottom 2 and up to the upper edge 3 thus defining a corresponding inner wall of each chamber 6 and 7.
It should be noted that the rib 5 comprises the two undulating walls spaced from each other by a constant mutual distance which is the width of the upper end 9 of the rib 5.
Preferably, the rib 5 has its upper end 9 coplanar with the upper edge 3 and connected at the edge 3 in at least two points which are opposite each other on the circumference formed by the edge 3 to define a further upper auxiliary edge.
This configuration makes it possible to increase both the seal between the two chambers 6 and 7, and the mechanical seal of the thermoformed body 1 .
In a third solution of the filter-bag 100 (Figures 13 to 17), the upper edge 3 has a circular shape and the rib 5 is configured with an annular extension inside the perimeter of the upper edge 3 to obtain a circular separation of the inner volume of the body 1 and in such a way as to define two separate chambers 6, 7 of different volumes.
In light of this, the rib 5 is ring-shaped and concentric relative to the upper edge in such a way as to define two chambers 6, 7 with annular extension.
Preferably, the two chambers 6, 7 are obtained with one inside the other and concentric with each other.
It should be noted that the rib 5 is formed around the centre of the bottom 2 and in such a way as to create a chamber 7 with a reduced volume surrounded by the other chamber 6 with a volume greater than the chamber 7. In this case, the rib 5 has a upper end 9 coplanar with the upper edge 3 but independent and without points of contact with the upper edge 3.
This invention also provides a method for making a filter-bag 100 for liquid infusion products of the type described above.
The method comprises the following steps:
- preparing a continuous strip S1 of thermoformable filter material (Figure 18);
- preparing a die 10 comprising a head 1 1 provided with a cavity 12 forming a volume for a body 1 of the filter-bag to be formed; the cavity 12 has a bottom 13, a mouth delimited on the perimeter by an upper flat edge 14 and at least one connecting wall 15 between the bottom 13 and the upper edge 14; the head 1 1 of the die 10 is equipped with at least one rib 16 extending from the bottom 13 towards the upper edge 14 in such a way as to define at least two chambers 17 and 18 which are separate from each other and included in the inner volume of the head 1 1 (Figure 18);
- preparing a punch 19 comprising a head 20 shaped to match the cavity 12 of the head 1 1 of the die 10 (Figure 18);
- positioning a portion of the continuous strip S1 of filter material between the die 10 and the punch 19 (Figure 18);
- hot plastic deforming of the portion of strip S1 of filter material by moving towards each other the corresponding heads 1 1 and 20 of the die 10 and of the punch 19 so as to obtain a body 1 having an inner volume defined by a bottom 2, a mouth delimited on the perimeter by an upper flat edge 3, at least one connecting wall 4 between the bottom 2 and the upper edge 3; the wall 4 being provided with at least one rib 5 extending from the bottom 2 towards the upper edge 3 in such a way as to define at least two chambers 6 and 7 for containing corresponding infusion products P1 , P2 separate from each other and included in the internal volume of the body 1 (Figures 19 to 22);
- dosing a first infusion product P1 in a first chamber (6 or 7) of the at least two chambers formed (Figure 23); - dosing a second infusion product in a second chamber (7, 6) still empty of the at least two chambers formed (Figure 23);
- preparing a flat piece 8 of non-thermoformable material (Figure 24);
- joining the piece of non-thermoformable material 8 on the edge 3 of the thermoformed body 1 to close the opening, in such a way as to form a filter-bag 100 (Figure 24).
Preferably, the flat piece 8 of non-thermoformable material has transparency characteristics (that is, it allows to an observer to look through the piece).
Advantageously, method according to the previous claim, wherein the step of preparing a flat piece of 8 of non-thermoformable filter material with transparency characteristics comprises preparing a flat piece 8 of non- thermoformable filter material with air permeability greater than 1000 cm3/cm2»s, preferably between 1000 and 10000 cm3/cm2»s, more preferably between 3000 and 7000 cm3/cm2»s.
The above-described formation methods, although illustrated for forming a filter-bag 100 of the type shown in Figures 1 to 6 (first embodiment illustrated), are applicable for the other types of filter-bag 100.
The only variant of a structural type relates to the die and the punch which will be configured according to the shape of the corresponding filter-bag 100.
Preferably, the step of hot plastic deforming the portion of strip S1 of filter material is carried out by (that is, it comprises a step of) heating the head 20 of the punch 19.
Alternatively, the step of hot plastic deforming the portion of strip S1 of filter material is carried out by preheating the strip S1 of filter material and using the head 20 of the punch 19 not heated.
Preferably, after the step of hot deforming the portion of strip S1 , there is a step of cutting of the thermoformed body 1 .
This cutting step is achieved, preferably, by moving cutting means positioned between the die 10 and the punch 19 (not illustrated). Preferably, the step of dosing the individual infusion products P1 and P2 may be performed simultaneously with independent dosers 21 and 22 (a doser for each product).
Alternatively, the dosing step is carried out in separate and successive phases, again with independent dosers 21 and 22 (a doser for each product).
Preferably, the piece 8 of filter material is associated, hot, on the upper edge 3 of the body 1.
Preferably, the piece 8 of filter material is unwound from a reel 23 of strip S2 of filter material and positioned on the edge 3 of the body 1 .
In light of this, a head 24 having a heated edge 25 and cutting means 26 carry out the association on the edge 3 of the body 1 and a relative cut of the strip S2 to define the closing strip 8.
