Description

MULTI-CHANNEL INSERT DEVICE, PARTICULARLY FOR CAPSULE OR DOSAGE, OR OTHER SIMILAR ARTICLES FOR LIQUID DISPENSER, ASSOCIATED METHOD AND MACHINE

The present invention relates to the field of dispensing liquid, in particular liquid food such as hot drinks. The invention finds particular application in machines for dispensing coffee, tea or hot chocolate, or other drinks.

In this type of machine, a carrier liquid, in particular hot water, is conveyed under pressure through a food substrate generally in powder and / or in fragments, which may include coffee, tea, chocolate or another food substrate. , or a mixture of at least two of these substrates.

The carrier liquid under pressure makes it possible to carry out a pressurized extraction of the substrate, which makes it possible to optimize the extraction of the aromas, for example for coffee or any other food product.

The carrier liquid thus conveyed solubilizes or extracts elements from the substrate in order to be able to distribute downstream a composition comprising said elements mixed with the carrier liquid.

In this area, to improve the quality of the liquid dispensed, it is necessary to have a constant calibration of the carrier liquid and of the substrate. To this end, the machines of the prior art provide calibrated injection systems of carrier liquid.

Some machines also provide receptacles where the substrate is measured and preferably packed, then placed on an external receptacle support opposite a column for distributing the carrier liquid.

Other machines called "pod" or "capsule", uses the substrate in capsules, pod or pod or pad, which is disposed on a suitable receptacle in the column of distribution of the carrier liquid. By "pod" is meant a substantially flexible system comprising, in the prior art, an upper filter, a lower filter containing substrate. We can speak in this present pod, "pod" or "pad" to designate this type of pod. By “capsule” is meant a structure similar to that of a pod in a substantially rigid receptacle hermetically closed by a cover.

The pod is permeable to the liquid and to the dispensed composition, so that the carrier liquid passes through the pod, before dispensing the composition downstream thereof. In the case of the capsule, it is generally permeabilized by the machine in use, in particular by drilling, before the passage of the carrier liquid.

In these types of machines, a significant pressure of carrier liquid must be applied to counteract the obstacles to the flow, in particular the substrate and the pores of the capsule or of the pod, of the receptacle or of the support as the case may be; and vigorously dissolve the entire substrate. This results in turbulent flows of carrier liquid going in all directions, and associated significant aroma and energy expenditure.

In addition, the efficiency of the machines can be improved by limiting the losses of liquid composition at the periphery of the capsule or of the external receptacle support.

A first objective of the present invention is to propose a means making it possible to increase the extraction pressure and / or solubilization while limiting the pressure applied in the liquid distributors and while maintaining good distribution efficiency.

A second objective is to limit the turbulent flow of carrier liquid in use, in order to optimize the extraction and / or solubilization of the aromas from the substrate, for example coffee or other food products such as tea, chocolate, cocoa. ...

A third objective is to improve the efficiency of solubilization of more substrate, in particular at the periphery of the capsule, of the pod, or of the receptacle.

A fourth objective is to distribute the substrate as well as possible (for example coffee, tea or other food products) inside the capsule, the pod or the receptacle.

To achieve these objectives, the invention provides an insert device for dispensing a liquid composition, in particular of liquid food, the insert device being configured to be disposed on a support permeable to the liquid composition and substantially impermeable. to a substrate, in particular a food-type substrate.

According to a first aspect, the insert device comprises a plurality of adjacent channels that are substantially parallel to each other, said channels being substantially sealed laterally, and configured to contain said substrate.

In particular, the channels are sealed from each other.

In addition, the channels can be substantially flexible and / or rigid, and preferably have a thickness sufficient to withstand the internal pressure inside the channels.

The channels can be integral with each other or movable individually.

In addition, the insert device is arranged so that a carrier liquid can pass through the channels of the insert device upstream, to dissolve and / or extract elements of the substrate by forming said liquid composition to be distributed downstream. support.

Advantageously, the insert device makes it possible to standardize the substrate container and to distribute the substrate in each of the channels and convey the carrier liquid therein. The channels serve as guides orienting the carrier liquid and limiting the turbulent flows. In use, less carrier liquid pressure can be applied since the effective extraction pressure in the channels is significantly increased. In addition, the liquid composition obtained has more elements, including in particular the aromas coming from the substrate in the case of coffee, tea, chocolate or cocoa for example.

This results in a significant improvement in the efficiency of the corresponding dispenser, for a given quantity of substrate.

Preferably, the substrate is sandwiched downstream by a woven and / or nonwoven filter and upstream by a woven and / or nonwoven filter. The assembly is made integral with the insert device by the use for example of a resin thus making it possible to obtain a combined assembly.

Another object of the invention relates to a pod for substrate, in particular a food-type substrate, for dispensing a liquid composition, the pod comprising an insert device according to the invention covered by an upper filter upstream of the insert device and a lower filter downstream of the insert device.

In particular, the lower filter paper and / or the upper filter paper are sealed, in particular welded, to the insert device.

The invention further relates to a capsule comprising a pod according to the invention disposed on an internal capsule support and hermetically closing the pod.

Advantageously, an insert capsule or pod is both effective through the channels of the insert device; fast and practical in that it is not necessary to handle the substrate; and stiffened by the presence of the insert device.

Preferably, the cap and / or the internal capsule support comprise a rigid and / or flexible perforable material, in particular aluminum, or a plastic polymer, a biodegradable polymer, a ferrous material, a non-ferrous metallic material, a resin-based material, paper, cardboard preferably with a layer of polyethylene and / or polylactic, a bio-based agro-material or a combination of at least two of these materials.

In particular, the cover is waterproof and perforable.

The invention relates to liquid dispensers 1, in particular of liquid food such as hot drinks, more particularly coffee machines, tea or hot chocolate, or other drink.

The invention relates more particularly to the establishment of substrate 2 of liquid dispenser 1, in particular in professional, semiprofessional machines or in capsule or pod machines or pod or pad or others.

In this type of machine (1), a substrate 2 in particular of the food type is placed on a support 3 permeable to liquids so that a carrier liquid 4 can be sent at high pressure to dissolve and / or extract elements of the substrate 2 to form the liquid composition 5 to be dispensed.

We can also speak of "carrier fluid" instead of "carrier liquid" especially for a mixture of at least one liquid and at least one gas such as hot water combined with steam.

The support may include a substrate receptacle 3a or a capsule receptacle or a pod receptacle 3b. The liquid composition 5 must then pass through the support 3 to be dispensed. The support 3 of the dispenser 1 is therefore permeable to liquids, and substantially impermeable to the substrate 2.

In these two types of machine, a high pressure of carrier liquid 4 must be applied to counteract the obstacles to the flow, in particular the fragments of substrate, the filters of a pod 7 in the case of a pod machine and in in addition to a capsule 7a in the case of a capsule machine, and vigorously solubilize the substrate 2 in its entirety. This results in turbulent flows of carrier liquid going in all directions, and associated expenditure of aromas and energy.

In addition, the efficiency of the machines can be improved by limiting the losses of liquid composition at the periphery of the capsule or of the substrate receptacle 6.

A first aspect of the invention relates to an insert device 8 configured to be placed in a dispenser column 1 of liquid composition 5, directly or indirectly on said support 3. The insert device 8 comprises a plurality of flexible channels 9 and / or adjacent rigid substantially parallel to each other. The channels 9 are substantially sealed laterally from each other, having a thickness sufficient to withstand the internal pressure inside the channels 9, so that the liquid does not flow laterally to the channels 9. In addition, the channels 9 are configured to contain said substrate 2. In use, the substrate 2 is in the channels 9, substrate 2 which is sandwiched downstream by a woven and / or nonwoven filter 11a and upstream by a woven filter and / or nonwoven 12a, made integral with the insert device 8 by the use for example of a resin thus making it possible to obtain a combined assembly.

The woven and / or nonwoven filters 11a and placed downstream and 12a placed upstream of the insert device 8 can also be made integral with the insert device 8 by welding, bonding or any other means, for example heat treatment or ultrasonic welding and the assembly is arranged upstream of the support 3.

Alternatively or in combination, it is possible to provide a filter insert device (not shown) having blind channels the end of which is pierced or pierceable so that the holes form a filtering means. In this variant, a woven or nonwoven filter would not be necessary on the drilled side.

In addition, the insert device 8 is arranged so that a carrier liquid 4 can pass through said channels 9 upstream, to dissolve and / or extract elements of the substrate 2 by forming said liquid composition 5 to be distributed downstream. of the support 3. The liquid composition can then flow into the rest of the dispenser, in particular from the coffee or tea or chocolate or cocoa or milk powder machine.

Advantageously, the insert device 8 makes it possible to standardize the substrate container so as to always have the same amount of substrate 2 dissolved by a constant flow of carrier liquid 4. In addition, the insert device 8 makes it possible to distribute the substrate 2 in each of the channels 9 separately. In addition, it allows the carrier liquid 4 to be conveyed separately in each of the channels 9. The channels 9 serve as guides orienting the carrier liquid 4 and limiting the turbulent flows.

In use, less carrier liquid pressure 4 can be applied. Indeed, the effective extraction pressure in the channels 9 is significantly increased by forcing the pressurized liquid of the carrier liquid 4 to pass through the channels 9. In addition, the liquid composition obtained has more elements, including in particular the aromas derived of the substrate in the case of coffee, tea or chocolate for example, in comparison with a dispenser 1 without insert device 8.

This results in a significant improvement in the efficiency of the corresponding distributor 1, for a given quantity of substrate 2.

According to a variant, the insert device 8 comprises as many channels as necessary to occupy a surface corresponding substantially to the support 3, in particular the cross section of the receptacle or of the capsule 7 and having an internal volume defined by a bottom as well as a flat edge 10 on the perimeter to delimit the opening of the channels 9, preferably more than two channels 9. In particular, the device comprises more than four channels 9, more particularly five to 200 channels 9 as illustrated in the figures. Advantageously, occupying the entire section of the support 3 and the liquid distribution column makes it possible to take advantage of the channels over the entire said section.

The channels 9 have a preferred thickness of between 50 μm and 4 mm, see more. Within these ranges, the tests have given satisfactory results in terms of flavor and pressure used.

According to a variant, the channels 9 have a polygonal section, in particular a hexagonal section. Advantageously, a polygonal section makes it possible to distribute several adjacent channels while avoiding having many dead volumes between the channels 9. A polygonal section, in particular a hexagonal section makes it possible to stiffen the entire structure

A shape having a polygonal section of more than 4 sides, such as a hexagonal section, makes it possible to improve the laminar appearance of the carrier liquid. In addition, the hexagonal shape gives an aesthetic appearance in the form of a honeycomb to the insert device 8.

One can also envisage cylindrical channels which are easier to manufacture, which reduces production costs.

One can also consider channels of cylindrical and / or polygonal shape.

According to a variant, the insert device 8 comprises a plastic polymer material, a biodegradable polymer, made of ferrous and / or non-ferrous material, resin-based material, food rubber, paper and / or cardboard with a layer of polyethylene and / or polylactic, the latter is certified compostable, in bio-based agromaterial from cereal and / or forestry industries.

Advantageously, a thermoplastic material is easy to implement and assemble at low cost. The channels can be manufactured by thermoforming, stamping, extrusion, thermoplastic injection or 3D printing.

Alternatively or in combination, the insert device 8 can comprise a ferrous and non-ferrous material or another metallic material, for example aluminum.

According to a variant, the insert device comprises a peripheral rim 10, preferably on the upstream side. The rim 10 improves the maneuverability of the insert device 8 in the manufacture or its use. The rim 10 also allows the insert device 8 to be easily positioned on its support or in the capsule 7a. The upstream flange 10 further facilitates the hermetic closure on the sides of the insert device 8 in certain variants. The rim 10 plays a sealing role in order to force the carrier liquid 4 to pass only through the channels 9 to exit into carrier liquid 5.

The flange 10 may be one end of the channels, making it possible to assemble them together to join them.

The invention also relates to a pod 7 or a capsule 7a of substrate, for dispenser 1 of a liquid composition, in particular a pod 7 or capsule 7a of coffee, tea, chocolate or another food product or a mixture at least two of these products. It is more generally a food-type substrate.

The pod 7 includes an insert device 8 as described above. The pod 7 comprises, or is used, with at least one means for retaining the substrate. The retention means comprises, or is preferably at least one filter detailed below.

In particular, the pod 7 comprises an upper filter 11a covering the insert device upstream thereof, and a lower filter 12a downstream thereof.

In particular, the pod comprises downstream a woven and / or nonwoven filter 11a and upstream a woven and / or nonwoven filter 12a, made integral with the insert device 8 by the use for example of a resin thus allowing to get a combined set.

The woven and / or nonwoven filter 11a and placed downstream and that 12a placed upstream of the insert device 8 can also be made integral with the insert device 8 by welding, bonding or any other means, for example heat treatment. or ultrasonic welding. The assembly contains the substrate 2.

The woven and / or nonwoven filter papers 11a and 12a are configured to contain said substrate 2, substrate 2 which is sandwiched downstream by a woven and / or nonwoven filter 11a and upstream by a woven and / or nonwoven filter woven 12a, made integral with the insert device 8 by the use for example of a resin or by welding, gluing or any other means, for example heat treatment or ultrasonic welding, thus making it possible to obtain a combined assembly.

This type of capsule is used in some pod machines. The pod can be that illustrated in FIGS. 1A to 2 and 4A to 4C. Advantageously, the insert device 8 makes it possible to significantly increase the mechanical rigidity of the capsule 7.

The invention further relates to a capsule 7a comprising an insert device preferably included in a structure similar to the pod 7 described above. In particular, the capsule comprises said filters.

More particularly, the capsule 7a comprises a flexible, waterproof and perforable cover 11 covering said insert device 8, which is disposed on an internal support 12 forming part of the capsule. In other words, the capsule 7a, comprising an internal support 2 and a cover 11, contains the insert device 8 and the substrate 2.

The known elements of tea or coffee capsules or machine supports and receptacles known in themselves, can be used in the context of the invention.

The insert device 8 is preferably secured to the cover 11 by sealing, heat treatment, ultrasonic welding, mechanical welding or by bonding.

Advantageously, this operation limits the transverse flows of carrier liquid at the level of the cover.

Alternatively or preferably in combination, the insert device 8 is secured to the internal support 12 of the capsule by sealing, heat treatment, ultrasonic welding, mechanical welding or by bonding. Advantageously, this operation limits the transverse flows of carrier liquid at the level of the internal support 12 of the capsule.

In a second step, the insert device 8 is placed in the internal support 12 of the capsule.

Then, in a third step, the rim 10 of the insert device 8 is secured to the rim of the support 12 by heat treatment, bonding, welding or any other means. Advantageously, this operation forces the carrier liquid to pass only through the substrate 2 at the level of the internal support 12 of the capsule.

In a fourth step, the channels 9 are filled with the substrate 2.

Then in a fifth step, the woven and / or nonwoven filter 11 is joined together with the upper part of the channels 9 as well as the rim 10 of the insert device 8 by hot treatment, gluing, welding or any other means.

Then, in a sixth step, the cover 11 is secured to the upper part of the channels 9 as well as the rim 10 of the insert device 8 with the woven and / or nonwoven filter 11a by heat treatment, bonding, welding or all other way.

According to a variant, the cover 11 and / or the internal capsule support 12 comprise a flexible and / or rigid and / or flexible material which is impermeable and perforable and / or already perforated, in particular aluminum or made of a plastic polymer material, biodegradable polymer, ferrous and / or non-ferrous material, resin-based material, food rubber, biosourced agro-material from cereal and / or forestry sectors, the latter is certified compostable. We can also consider using kraft paper.

This type of capsule is used in some other rigid capsule machines. The capsule can be that illustrated in FIGS. 3A to 3B and 5 to 6. Advantageously, the insert device 8 makes it possible to significantly increase the mechanical rigidity of the center of the capsule 7a.
