Description

Package for preparing a beverage, method of manufacture and method of use

Technical Field

The present invention relates to a capsule comprising a hollow body made of plant material designed to receive an infusible product also made of plant material. The invention also relates to a method for manufacturing the packaging body and a using method thereof.

The field of the invention relates to a capsule for a beverage preparation machine, in particular a percolator-type machine for preparing coffee, such as Nespresso, Keurig (registered trademark) or other types.

Background

Conventionally, the packaging used in known machines is made of aluminium or plastic, which is unsatisfactory from an environmental point of view.

Some manufacturers are highlighting the ecological argument for selling packages made of oxidatively degradable plastics whose decomposition is accelerated by exposure to heat, light or under the effect of mechanical stress. When disposed of outdoors, such as in landfills, these plastics take between two and five years to break down into small pieces, after which the natural breakdown of these small pieces is very slow. Under these conditions, these plastics cannot be classified as biodegradable. In addition, these plastics are not compostable because the debris denatures the compost to the point where it cannot be used. Finally, these plastics are not recyclable via traditional methods, since the additives that promote their decomposition also affect the mechanical and chemical properties of the recycled product.

Furthermore, existing machines and packages are mainly designed specifically for coffee, and not for preparing products such as tea or herbal teas waiting for brewing. The machine has specific settings (temperature, pressure, water flow rate, perforation mechanism, duration of the machine cycle, etc.) while the package has a specific configuration suitable for the machine and for preparing coffee. In practice, however, the optimal preparation conditions for the product to be brewed are different from the conditions for preparing coffee. Therefore, when the capsule designed for coffee is filled with the product to be brewed and then used in a coffee machine, the result is unsatisfactory from the point of view of taste and for maintaining the full characteristics of the plant.

Under these circumstances, manufacturers have developed machines and packaging specifically designed for tea. However, for users who already own a Nespresso or other type of coffee machine, this requires them to acquire a new machine for tea. Furthermore, most of the packages for tea are made of the same material as the packages for coffee and therefore have the same drawbacks.

EP2,573,008 describes a package comprising a hollow body made of a first plant material and an infusible product made of a second plant material. The body has an opening that is sealed by the lid to contain the infusible product. The capsule is ecological and of simple construction, but is not suitable for use in machines originally designed for preparing coffee.

Disclosure of Invention

The aim of the present invention is to propose an ecological capsule suitable for preparing a product to be brewed in a machine originally designed to prepare coffee, in particular a machine for preparing coffee via percolation (corresponding to the water passing through the capsule under high pressure), such as a Nespresso or other type of machine.

To this end, the invention relates to a capsule comprising a hollow body made of a first plant material and designed to receive an infusible product made of a second plant material, said body having an opening sealed by a lid to contain the infusible product, characterized in that said capsule has at least one breakable projection projecting from said body opposite said opening and breakable by a machine intended to infuse said infusible product.

Thus, the capsule according to the invention enables to optimize the quantity and flow rate of water required for brewing the infusible product, thus obtaining satisfactory aroma intensity and flavor with reduced brewing time, while maintaining the full characteristics of the plant. The percolator machine then becomes a multifunctional machine which allows the preparation of coffee, but also other types of beverages, depending on the nature of the infusible product. Furthermore, the package has a biodegradable and compostable container and contents, making it environmentally friendly.

Furthermore, instead of food applications, the package may be used for pharmaceutical applications. Finally, although the package is usually used for preparing hot beverages, it can also be used for preparing cold beverages.

According to other advantageous features of the invention considered alone or in combination:

-the or each breakable protuberance is bordered by at least one locally weakened inner section portion (edged).

The or each breakable projection is bordered by three locally weakened inner section portions.

The or each locally weakened inner section is bordered on one side by a first portion belonging to the breakable projection and on the other side by a second portion belonging to the top of the body.

The or each locally weakened inner section has a radial width that decreases towards an area of zero or almost zero thickness.

The region is located at the connection of the first part and the second part.

-the or each breakable projection has four outer facets (facets).

The package has several breakable bumps regularly spaced around a central axis and collectively covering an angular area of at least 240 degrees around the central axis.

The breakable projections together cover an angular area of at least 280 degrees around the central axis, for example an angular area of 320 degrees around the central axis.

The number of breakable bumps is four.

Adjacent breakable bulges are connected together by a locally weakened intermediate section.

The package has a single annular breakable projection centered on the central axis.

The body has an internal annular reinforcement at the base of the at least one breakable projection.

The package has reinforcing ribs arranged in the body.

The reinforcing rib extends between a first circle at the edge of the at least one breakable projection and a second circle located away from the opening.

-each reinforcing rib has a thickness that increases overall from the first circle towards the second circle.

The cover is made of a third plant material, preferably food grade paper.

The packaging body has an outer collar formed radially on the body in the vicinity of the opening and constituting, on the one hand, a support for attaching the lid and, on the other hand, a seat for sealing when the packaging body is positioned in the machine.

-the infusible product comprises at least one component selected from tea, herbal tea, plants, phytotherapeutic drugs, flavourings, vegetables, fruits, natural spices, essential oils or a mixture of several of these components.

In the case of pharmaceutical applications, the infusible product also comprises at least one pharmaceutically active substance mixed with at least one of the above-mentioned ingredients.

The subject of the invention is also a method for manufacturing a package as described above. The method is characterized in that it comprises the following successive steps:

a) the body is manufactured according to the following successive steps:

a1) cutting all or most of the aerial parts of the plant into pieces;

a2) grinding or shearing the pieces until particles having an average size between 0.01mm and 10mm are obtained;

a3) adjusting the water content of the particles until an overall hydration rate of between 10% and 35% is reached; and

a4) shaping plant material to form the body;

b) the product to be infused is manufactured according to the following successive steps:

b1) arranging dry or fresh plant material in contact with a solvent such as water;

b2) extracting an active ingredient from a plant material;

b3) drying the plant material that has undergone extraction in the presence of the proportions obtained at the end of this extraction, so as to allow the active ingredient to be immobilized on the plant material and obtain the product to be infused;

c) filling the body with the product to be brewed;

d) the opening is sealed by a lid.

The subject of the invention is also a method for using a package as described above. The method is characterized in that it comprises an operation of punching at least one breakable projection by a machine intended to brew an infusible product.

Detailed Description

In fig. 1 to 9, a capsule 1 according to the invention is shown, comprising a hollow body 2 intended to receive an infusible product 3. For simplicity, the product 3 is not shown, but its position within the body 2 is indicated by the dashed arrows in fig. 1, 2, 4 and 5.

In the case of food applications, the infusible product 3 comprises at least one ingredient selected from tea, herbal tea, plants, phytotherapeutic drugs, flavourings, vegetables, fruits, natural aromas, essential oils or a mixture of several of these ingredients. In other words, each of the above-mentioned ingredients can be used alone or mixed with the others to obtain the product 3.

In the case of pharmaceutical applications, the infusible product 3 comprises a solid excipient, preferably an ingredient of the type described above, and at least one pharmaceutically active substance mixed with the solid excipient.

The package 1 also has breakable projections 6, reinforcing ribs 7, an outer collar 8 and an inner collar 9. The projections 6 are breakable by a machine intended to brew the product 3, in particular a machine of the Nespresso type.

The package 1 has a central axis X1 which extends in its height direction and forms a rotational axis for the body 2. In the example from the figures, the package 1 has a height equal to 28.35mm between the opening 4 and the collar 8 on the one hand and the vertex of the body 2 on the other hand. In this case, the package 1 has dimensions suitable for its use in a Nespresso-type machine.

Alternatively, the capsule 1 can be provided in different shapes and sizes, adapted to be used in another type of machine, in particular a percolating pot machine, for example of the Keurig or other type.

The body 2 has an opening 4 sealed by a lid 5 for containing the product 3. Again for the sake of simplicity, only the cover 5 is shown on fig. 5. The opening 4 has a circular shape, while the cover 5 has a disc shape centered on the axis X1. The diameter of the cap 5 is larger than the diameter of the opening 4 so that the cap 5 can be secured to the collar 8.

The body 2 is generally dome-shaped, closed at its apex and open near the opening 4. From the opening 4 to the apex, the body 2 has a first inclined portion 21, a second inclined portion 22 inclined more than the portion 21, a hemispherical portion 23, and a hollow 24 formed at the apex. In the example from the figure, relative to the axis X1, the portion 21 is inclined at an angle of 2 degrees, while the portion 22 is inclined at an angle of 9 degrees. The hollow 24 corresponds to the point of injection of the material of the body 2 during its manufacture. The hollow 24 has a concave profile on the outside of the body 2 and a convex profile on the inside of the body 2.

The body 2 also has an inner reinforcement 25 having an annular shape centred on the axis X1. The reinforcement 25 is located in the portion 23 of the body 2, at the base of the projection 6. The reinforcement 25 constitutes a frame to prevent deformation of the body 2 when a machine receiving the package 1 applies force to punch the bump 6.

The body 2 has a generally constant thickness e2 equal to 0.6mm, with the exception of the reinforcement 25, where the thickness e2 is greater. Further, the thickness of the package body 1 is locally increased or decreased at the bump 6. Further, the thickness of the package 1 increases in the vicinity of the rib 7 and the ring 9.

In the case of food applications, the packaging 1 is entirely plant-based, i.e. the container (body 2 and lid 5) and the contents (product 3) are entirely made of readily biodegradable plant material. In the case of pharmaceutical applications, the content (product 3) may comprise at least one pharmaceutically active substance added to tea, herbal tea, plants, phytotherapeutic drugs, flavorings, vegetables, fruits, natural fragrances, essential oils.

Thus, the package 1 is recyclable, biodegradable and compostable. The package 1 provides an ecological alternative to contaminated aluminum or plastic boxes.

Furthermore, the body 2 and the lid 5 are adapted to be in contact with the food and constitute a barrier to gases, allowing the capsule 1 to contain and protect the product 3 before brewing in the machine.

The body 2 is made of a plant-based material, for example based on corn starch, produced from cereal plants. Preferably, the body 2 is made of composite material VEGEMAT (registered trademark) of biological origin according to the teachings of document FR 2,783,740. The body 2 is therefore compostable according to the standard EN 13432 described below.

In a first step, the aerial parts of the plant, or a large part of these aerial parts, are cut into pieces. In a second step, the chips are ground or sheared until particles having an average size between 0.01mm and 10mm are obtained. In a third step, the water content of the particles is adjusted until an overall hydration rate of between 10% and 35% is reached. In a fourth step, the plant material is shaped to obtain a body 2.

Other advantageous features of the VEGEMAT material and its method of manufacture are described in detail in the above-mentioned documents.

The product 3 to be infused is prepared from plant extracts grown according to organic or integrated agricultural practices. Preferably, product 3 is prepared according to the HTVE ("high tech of plant extracts", registered trademark) process, according to the teachings from document EP2,080,436.

In the first step, similar to the steeping step, plant material (dry or fresh, such as tea leaves or mixtures for herbal teas, plants, phytotherapeutic drugs, flavorings, vegetables, fruits) is placed in contact with a solvent. In the case of food applications, the solvent is preferably water. Alternatively, in the context of the preparation of other products (e.g. for pharmaceutical applications), the aqueous solvent may be replaced by an aqueous organic or purely organic solvent. In particular, the solvent may be a hydro-alcoholic solvent, such as 50/50 (vol) water/alcohol mixture, especially 50/50v/v water in ethanol. Non-limiting examples of organic solvents that can be used are ethanol, methanol, acetone, or mixtures thereof.

In a second step (which may be subsequent to or simultaneous with the first step), the active ingredient is extracted from the plant material (preferably by heating and under reduced pressure).

In a third step, the plant material subjected to extraction is dried in the presence of the proportions obtained at the end of the extraction, so as to allow the active ingredient to be immobilized on the plant material.

By using this method, the aroma intensity of the brew and the overall characteristics of the plant are maintained. In addition, the brewing time is reduced. The infusion of the product 3 is therefore compatible with the short cycle of the percolator machine for preparing coffee from the capsule.

Further variants and advantageous features of the method are described in detail in the above-mentioned document.

According to European Union regulations 1935/2004, directives 80/590/EEC and 89/109/EEC, and Title 21CFR Ch.I § 176.170 and 176.180 of the U.S. food and drug Act, lid 5 is made of filter paper, preferably micro-perforated food grade filter paper. The lid 5 has an optimum strength and permeability to allow a constant flow rate of water to circulate throughout the brew cycle of the product 3 in the machine.

In a preferred embodiment, the lid 5 is made of micro-perforated food grade filter paper having a thickness of about 0.2mm, 52g/m²And 58g/m²A surface density of between 4.5% and 6.5%, a dry tensile strength MD of between 1kN/m and 1.5kN/m and a dry tensile strength CD of between 0.8kN/m and 1.2kN/m, a wet tensile strength MD of between 0.3kN/m and 0.4kN/m, and an elongation at break of between 6% and 7%.

In practice, the packaging 1 is therefore compostable as a whole, according to the standard EN 13432, which is reflected by four main requirements: biodegradability (90% biodegradation in six months), decomposition (total residue greater than 2mm in length must be less than 10% of the initial mass after fragmentation into compost over three months), synthesis (must take into account the maximum levels of volatile solids defined and heavy metals), ecotoxicity (the quality of the compost must not be modified and the residue must not be toxic to the environment).

By complying with this standard, the package 1 according to the invention is distinguished from existing packages which are less environmentally friendly. In particular, the package 1 is distinguished from packages which have been proposed for marketing purposes as biodegradable and compostable, but which do not meet this standard.

Furthermore, as described in detail below, the package 1 has specific structural features that optimize its use in a machine.

The projection 6 is formed as a projection on the top of the body 2, more precisely on the portion 23 opposite the opening 4. The projections 6 are designed to be broken by a machine adapted to receive the capsule 1 and to brew the product 3, in the case traditionally used for preparing coffee. The projection 6 is thus considered to be breakable, breakable or breakable.

In the example of the figures, the package 1 has four protrusions 6 regularly spaced from the hollow 24 around a central axis X1. Alternatively, the package 1 may have a different number of bumps 6, and these may have a different shape and/or have a different size than described below.

On the outside of the capsule 1, each projection 6 has four

facets

61, 62, 63 and 64, namely a lateral facet 61 oriented towards the outside with respect to the axis X1, an upper facet 62 oriented away from the opening 4, and two

radial facets

63 and 64 having a smaller dimension on the edges. The edges between the facets 61-64 may be more or less rounded. Each bump 6 therefore has a certain volume, which allows it to be broken, rather than perforated, as in other known packages.

Inside the capsule 1, each projection 6 is bordered by four

rectilinear sections

65, 66, 67 and 68, comprising three locally weakened

sections

66, 67 and 68, obtained by locally reducing the thickness of the body 2. The section 65 is located on the reinforcement 25 of the body 2.

Sections

65 and 66 are curved, while

sections

67 and 68 are straight. The sections 65-68 are arranged opposite the facets 61-64, respectively.

For a single protrusion 6, about axis X1,

facets

63 and 64 are separated by an angle α e (alpha e) of 62 degrees, while

segments

67 and 68 are separated by an angle α i (alpha i) of 70 degrees, thus, the four protrusions 6 collectively cover an angular area equal to 280 degrees about axis X1, although protrusions 6 have a number of different shapes and/or sizes, the angular area covered is preferably between 260 and 340 degrees.

When the machine receiving the packages 1 exerts a punching force on their upper partial surface 62, the projections 6 (at least one of the four) yield near the locally weakened

sections

66, 67 and 68 and are slightly pressed towards the inside of the body 2 by pivoting about the section 65. A space is thus formed between each of the rupture projections 6 and the rest of the body 2, which allows water to penetrate under pressure into the capsule 1 in order to brew the product 3. The water circulates rapidly in the packaging 1 and is instantaneously loaded with the most active ingredient from the product 3.

In practice, in percolator machines, the quantity of water and the flow rate required for brewing the product 3 are different compared to the preparation of coffee. The projection 6 equipping the capsule 1 according to the invention makes it possible to obtain satisfactory results, i.e. satisfactory aroma intensity and flavour, in a reduced brewing time, while maintaining the characteristics of the plant.

FIG. 7 shows a partially weakened straight section 66; however, the following description applies equally to

sections

67 and 68. The segment 66 is bordered on the one hand by a portion 661 belonging to the bump 6 and on the other hand by a portion 662 belonging to the vertex of the capsule 1, between the bump 6 and the hollow 24. The section 66 has a tapered profile, the width of which (defined radially, in a plane including the axis X1) decreases from the inside towards the outside of the capsule 1, thus forming a local thinning of the body 2. The width of section 66 decreases up to a region 660 at the junction of

portions

661 and 662. Within the scope of the invention, body 2 of package 1 is manufactured so that region 660 has a thickness of zero or almost zero, thereby causing

portions

661 and 662 to separate, breaking through bumps 6.

The reinforcing ribs 7 are arranged within the body 2 to give the package 1 mechanical strength that is well suited to the desired application. Tests have shown that when the package 1 is not ribbed or the body 2 is made with a small thickness, there is a risk of deformation or breakage of the body 2 under the action of the machine, which disturbs the preparation of the product 3.

In the example of the figures, the package 1 has twelve ribs 7 regularly spaced around the central axis X1 and the hollows 24. Alternatively, the package 1 may have a different number of ribs 7, for example six, eight or eighteen, and these may have a different shape and/or have different dimensions than those described below.

Each rib 7 has two

longitudinal ends

71 and 72, two concave

inner surfaces

73 and 74 oriented facing axis X1, and two flat lateral surfaces 75 and 76 radial to axis X1, surface 73 extends almost over the entire length of rib 7, while surface 74 is formed only at lower end 72, between

surfaces

75 and 76, rib 7 extends around axis X1 along an angle β 7 equal to 4 degrees.

Along their longitudinal direction, the ribs 7 extend in a middle zone Z2 of the body 2 between two imaginary circles C4 and C6, the middle zone Z2 extending partly through the portion 22 and partly through the portion 23 of the body 2, parallel to the axis X1, the ribs 7 have a length L7 corresponding to the gap between the two circles C4 and C6, the circle C6 is located on the edge of the projection 6 along the reinforcement 25 and the section 65, the circle C4 is located at a distance from the opening 4, i.e. parallel to the axis X1, at a predetermined distance d7 from the opening 4.

In the example of the figures, the length L7 is about 13.1mm, while the distance d7 is about 11.1mm, in other words the ratio of the length L7 to the distance d7 is about 1.18, although the ribs 7 have different shapes and/or dimensions, this ratio is preferably between 1 and 1.4.

The ribs 7 have a thickness e7 that increases overall from their end 71 towards their end 72, i.e. from the circle C6 towards the circle C4. The thickness e7 decreases only near the surface 74. The rib 7 has a thickness e7 of almost zero in the vicinity of the reinforcing members 25 over the circle C6, and is about 1mm over the circle C4.

The presence of the ribs 7 prevents the body 2 from breaking when the machine receiving the capsule 1 exerts a punching force on the projections 6. Thus, in the best case for the infusion product 3, the water is able to penetrate under pressure into the capsule 1.

An outer collar 8 is formed radially on the body 2 in the vicinity of the opening 4. The collar 8 has a flat lower surface 81 constituting an attachment support for the lid 5 in order to seal the opening 4 after filling the body 2 with the product 3. The collar 8 has an upper surface 82 without projections 83, which constitutes a seat for sealing the capsule 1 positioned in the machine. The projection 83 has an annular shape centred on the axis X1 and is intended to be pressed against a machine part. Before, during and after the stamping of the projections 6, during the brewing of the product 3 in the machine, a seal is ensured.

The annular ring 9 is formed inside the body 2, more precisely in its portion 22 between the opening 4 and the rib 7. The ring 9 has an annular shape centred on the axis X1. The collar 9 is a small plastic undercut for retention during ejection of the body 2 from its mould.

Furthermore, the package may be shaped differently from that in fig. 1 to 9 without departing from the scope of the invention.

Furthermore, the manufacturing method and the use method of the package 1 may be different from the above examples without departing from the scope of the present invention, especially in the case of pharmaceutical applications.

Further embodiments of the package 1 according to the invention are shown in fig. 10 to 17. Their constituent elements are equivalent to those in the first embodiment described above, and have the same reference numerals for the sake of simplicity.

Fig. 10 to 14 show a package 1 in which the projection 6 and the locally weakened section differ from the first embodiment.

Fig. 10 shows a projection 6 that is wider than in the first embodiment.

Fig. 11 shows a section 66 formed by a rounded corner between

portions

661 and 662, in the hollow of which a zone 660 of zero or almost zero thickness is located. The profile defined by the inner surface of portion 661 and the outer surface of portion 662 is curvilinear. The profile defined by the outer surface of portion 661 and the inner surface of portion 662 is a sinusoidal line.

Fig. 12 shows a section 66 with a circular profile, formed by a concave cut inside the body 2. Region 660 is located at the hollow of the cut-out. The profile defined by the inner surfaces of

portions

661 and 662 in one aspect and their outer surfaces in another aspect is a curve.

Fig. 13 shows a section 66 formed by a fillet between

portions

661 and 662, in the hollow of which an area 660 is located, and the protuberance 6 stops abruptly in the vicinity of the facet 62. The profile defined by the outer surface of portion 661 and the inner surface of portion 662 is a straight line.

Fig. 14 shows the sections 66 on both sides of the

portions

661 and 662, respectively, formed by two concave cuts on the inside and outside of the body 2. The region 660 is located between the two incisions. The profile defined by the inner surfaces of

portions

Fig. 15 shows a package 1 in which, for a single bump 6, the

segments

67 and 68 are separated by an angle α i of 80 degrees defined around X1, the bumps 6 therefore together cover an angular area equal to 320 degrees around the axis X1, since this angular area is wider than in the first embodiment, the risk of the punch of the machine coming to rest on the space between two bumps 6 is reduced, in other words, the breaking of the bump 6 is facilitated.

Fig. 16 shows a package 1 in which a locally weakened inner intermediate section 69 is formed between the

sections

67 and 68 of two adjacent projections 6, in continuation of the section 65. Thus, the piercing of the projection 6 is facilitated.

Fig. 17 shows a package 1 having a single breakable bump 6 centered on a central axis. In other words, the breakable projection covers an angular area of 360 degrees around the axis X1. The single segment 65 and the single segment 66 having a circular shape extend around the axis X1. According to a possible variant, the section 65 may be a locally weakened circular line similar to the section 66. Such a package 1 is very suitable for certain types of machines.

Furthermore, technical features of the plurality of embodiments mentioned in the above description may be combined with each other in whole or in part. Thus, the package 1 can be adjusted in terms of cost, functionality and performance.
